\nIn this first ever show on Hacker Public Radio, StankDawg and Enigma introduce HPR.\n

\n

\nThe story of Hacker Public Radio begins where Radio FreeK America leaves off. StankDawg was a busy with Binary Revolution Radio and so the idea lay dormant for some time. Then droops, another podcaster (Infonomicon) who was inspired by RFA got together with dosman to start TWaTech Today with a Techie, a pun on Twit. About a year in Enigma took over operations from portrello.\n

\n

\nContinuing on from Today with a Techie, HPR will air anything that is Of interest to hackers. Think, hacking, phone preaking, politics, survival, caffeine, linux, movie reviews, game reviews, etc. There is no restriction on the length but the shows will have the intro and outro added, which was kindly donated by slick0. Additionally there is the option to have miniseries where the hosts can have running topics to cover an issue in more detail. A mini series can also be open to so that multiple people can contribute to one topic.\n

\n

\nAbove all HPR is a Community Network.\n

Today deepgeek talks about Customization being the lost reason in switching from windows to Linux. He points out that the PC stands for Personal Computer. To many on windows this means they can change the desktop wallpaper.

\n

He believes that by explaining the ability to Customise the working environment is the power of Linux. You can customise the services running, whether you wish to use a command line interface, a basic Window Manager, or a Lightweight or Full Featured Desktop Environment

\n

Finally he ends with a tribute to Seymour Cray

\nhttps://en.wikipedia.org/wiki/Asus_Eee_PC\n

\n
\nThe Asus Eee PC is a netbook computer line from ASUSTeK Computer Incorporated, and a part of the Asus Eee product family. At the time of its introduction in late 2007, it was noted for its combination of a lightweight, Linux-based operating system, solid-state drive (SSD), and relatively low cost. Newer models added the options of Microsoft Windows operating system, rotating media hard disk drives (HDD) and initially retailed for up to 500 euro.
\nThe first Eee PC was a milestone in the personal computer business, launching the netbook category of small, low cost laptops in the West (in Japan, subnotebooks had long been a staple in computing). According to Asus, the name Eee derives from \"the three Es\", an abbreviation of its advertising slogan for the device: \"Easy to learn, Easy to work, Easy to play\".
\nIn January 2013, Asus officially ended production of their Eee PC series due to declining sales as a result of consumers favoring tablets and Ultrabooks over netbooks. However they subsequently restarted the line with the release of the 1015 series.\n
\n

\nThey also review backtrack:
\nhttps://en.wikipedia.org/wiki/BackTrack\n

\n
\nBackTrack was a Linux distribution, superseded by Kali Linux, that focused on security based on the Ubuntu Linux distribution aimed at digital forensics and penetration testing use. In March 2013, the Offensive Security team rebuilt BackTrack around the Debian distribution and released it under the name Kali Linux.\n

RDBMS - Relational Database Management System

\n\n

Relational Model: when there are relationships between items of\ndata such as products, customers and orders

\n\n

A database contains two-dimensional tables which are similar in\nconcept to spreadsheets. Each table contains columns and rows like\na spreadsheet, but these are called fields and records in\ndatabase terminology

\n\n

Data is stored in tables but is broken down into the most efficient form\nsuch that there is no duplication. This process is called\nnormalisation.

\n\n

Fields have data types associated with them, such as numeric fields for\nstoring numbers or text fields for storing text.

\n\n

Tables have keys to simplify searching. Primary keys are\nused to make records in a table unique.

Review Question:

\n

Try answering the follow review question by leaving a comment or answering it in your head. If you want you can even write it down on paper.

\n

Write an algorithm for your morning routine. From the time the alarm clock rings until you leave the house for work or school.

\n

If you're like me and do not have a job try writing an algorithm on how to write a resume.

HPR Circuit Bending

\n\n\n\n

Circuit bending is the creative, DIY (Do It Yourself) short-circuiting of electronic devices such as low voltage, battery-powered guitar effects, children's toys and small digital synthesizers to create new musical instruments and sound generators. Emphasizing spontaneity and randomness, the techniques of circuit bending have been commonly associated with noise music, though many more conventional contemporary musicians and musical groups have been known to experiment with \"bent\" instruments. Circuit benders remove the rear panel and connect circuits on a trial and error basis. More experienced benders use a soldering iron and add other components such as potentiometers, resistors or capacitors, which creates an even broader range of sounds.

\"Hacker\" :n

\n
    \n
  1. A programmer who breaks into computer systems in order to steal or change or destroy information as a form of cyber-terrorism [syn: cyber-terrorist, cyberpunk]
    2. \n
  2. A programmer for whom computing is its own reward; may enjoy the challenge of breaking into other computers but does no harm; \"true hackers subscribe to a code of ethics and look down upon crackers\"
    3. \n
  3. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary.
    4. \n
  4. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming.
    5. \n
  5. A person capable of appreciating hack value.
    6. \n
  6. A person who is good at programming quickly.
    7. \n
  7. An expert at a particular program, or one who frequently does work using it or on it; as in `a Unix hacker'. (Definitions 1 through 5 are correlated, and people who fit them congregate.)
    8. \n
  8. An expert or enthusiast of any kind. One might be an astronomy hacker, for example.
    9. \n
  9. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations.
    10. \n
  10. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence `password hacker', `network hacker'. The correct term for this sense is cracker.
    11. \n

Locations\n\nMenu files (requires root to edit)\n

    \n
  • /usr/shar/applications
    • \n
\n\nIcon files\n
    \n
  • /usr/share/pixmaps
    • \n
  • /usr/share/icons/foo
    • \n
\n\n

Edit files in plain text editor like GEdit

\n\nEllements pointed out in episode (there are plenty more, they vary per app, & distro)\n
    \n
  • Name : the name it will display on the menu (may need to change Name[foo] to reflect your language)
    • \n
  • Language : speaks for itself
    • \n
  • Comment : the rollover text
    • \n
  • Exec : the command it will execute when clicked
    • \n
  • Icon : the path to the icon shown in the menu
    • \n
  • OnlyShowIn : useful when trying to find why an application may not be showing the menu
    • \n\n
  • Terminal : runs the command in a terminal
    • \n\n
  • Categories : (I think) this is the submenu groups where it'll appear on the menu
    • \n
\n

Changes sometimes take a little while to update, restarting X or rebooting will force it to re-read that folder and apply the changes.

\nXCFE Tip\n
    \n
  • Right click to edit menu. Click on something like a separator, move it up, then down to it's original place. Save.

This presentation will describe these patterns, and provide an overview of the Open Source software available to implement them. About Dan: Dan Hanks has been involved with Linux System administration since 1998, when he worked for EagleNet Online, a small ISP in Provo, which, in a sense, was the birthplace of PLUG. After EagleNet he worked as a systems and database administrator for Nothsky/About.com/Primedia/United Online and is currently a system administrator for Omniture. He has varied interests, ranging from computers and technology to astronomy, geology, music, art, and family history research. He holds a Bachelor's degree in Computer Science from BYU, and is the father of 4 adventuresome children. He (occasionally) blogs at https://brainshed.com, and tweets as @danhanks.","hostid":100,"series":0,"explicit":1,"license":"CC-BY-NC-SA","tags":"physical infrastructure,data center","version":0,"downloads":1949,"valid":1}, {"id":367,"date":"2009-05-28","title":"Screw you Hacker","duration":406,"summary":"A song by Chad from the Linux Basement","notes":"another song by Chad from the linux basement","hostid":101,"series":22,"explicit":1,"license":"CC-BY-NC-SA","tags":"songs,hacker,buffer overflow","version":0,"downloads":1700,"valid":1}, {"id":368,"date":"2009-05-29","title":"GPS with gpsbabel, gpicsync and Google Earth","duration":4349,"summary":"Utah Open Source Conference - GPS","notes":"Marc Christensen presents on Geo Tagging pictures and overlaying GPS Data aligned with photos on Google Map and Google Earth","hostid":100,"series":0,"explicit":1,"license":"CC-BY-NC-SA","tags":"GPS,gpx file,gpsbabel,gpicsync,file conversion","version":0,"downloads":1514,"valid":1}, {"id":369,"date":"2009-05-29","title":"UCLUG May Meeting","duration":6175,"summary":"Carolina Linux User Group Meeting - GnuCash","notes":"Upstate Carolina Linux User Group","hostid":77,"series":0,"explicit":1,"license":"CC-BY-NC-SA","tags":"finance,GnuCash,online banking,SELF,ffmpeg,Android","version":0,"downloads":1563,"valid":1}, {"id":370,"date":"2009-06-01","title":"How I Found Linux 004","duration":1755,"summary":"Monsterb introduces audio clips sent in by Linux users","notes":"How I Found Linux 004

For decades it has been good enough for most people. However, it is starting to show its age. In the highest security settings, a more fine grained control system is needed. In the past, this meant using expensive, complicated, special purpose versions of Unix: trusted systems. (Trusted Solaris, Trusted AIX, Trusted HP-UX) SELinux, created by the NSA, is the most mature and complete response to the need for Trusted Linux systems. Unfortunately, because of the difficulty creating and maintaining trusted systems, their success has been limited. This is no longer acceptable. Today, even desktop systems and cell phones need high quality security. Imagine being able to sandbox your Web browser and e-mail client. The traditional Unix model makes this difficult and only partially possible. SELinux, on the other hand, makes fine grained security available to everyone. When it first appeared, SELinux was hard to learn and mysterious to troubleshoot. As a result, many people fear it. However, SELinux and the tools to manage it have come a long way. It's time to lay fear aside. Stuart will teach what SELinux is, why it is great, basic troubleshooting and maintenance.","hostid":100,"series":0,"explicit":1,"license":"CC-BY-NC-SA","tags":"SELinux,NSA","version":0,"downloads":1571,"valid":1}, {"id":372,"date":"2009-06-03","title":"All Songs Considered 8: Gnu Day","duration":280,"summary":"A song by Chad from Linux Basement","notes":"Another Song by Chad from the linuxbasement","hostid":101,"series":22,"explicit":1,"license":"CC-BY-NC-SA","tags":"Songs,GNU Linux","version":0,"downloads":2066,"valid":1}, {"id":373,"date":"2009-06-04","title":"Qemu","duration":1289,"summary":"Klaatu discussed the Qemu emulator","notes":"

\n

Some Common STOP codes: Bug Check 0xA: IRQL_NOT_LESS_OR_EQUAL

The \nIRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x0000000A. This indicates that \nMicrosoft Windows or a kernel-mode driver accessed paged memory at \nDISPATCH_LEVEL or above.

The following parameters are displayed on \nthe blue screen. Parameter Description 1 Memory referenced 2 IRQL at time of \nreference 3 0: Read 1: Write 4 Address which referenced memory Cause This bug \ncheck is issued if paged memory (or invalid memory) is accessed when the IRQL is \ntoo high. The error that generates this bug check usually occurs after the \ninstallation of a faulty device driver, system service, or BIOS. If you \nencounter bug check 0xA while upgrading to a later version of Windows, this \nerror might be caused by a device driver, a system service, a virus scanner, or \na backup tool that is incompatible with the new version.\nIf a kernel debugger is available, obtain a stack trace.\n

\n
\n

To resolve an error caused by a faulty device driver, system service, or BIOS
1. Restart your \ncomputer.
2. Press F8 at the character-based menu that displays the operating \nsystem choices.
3. Select the Last Known Good Configuration option from the \nWindows Advanced Options menu. This option is most effective when only one \ndriver or service is added at a time.

To resolve an error caused by an \nincompatible device driver, system service, virus scanner, or backup tool
1. \nCheck the System Log in Event Viewer for error messages that might identify the \ndevice or driver that caused the error.
2. Try disabling memory caching of the \nBIOS.
3. Run the hardware diagnostics supplied by the system manufacturer, \nespecially the memory scanner. For details on these procedures, see the owner's \nmanual for your computer.
4. Make sure the latest Service Pack is installed.
5. \nIf your system has small computer system interface (SCSI) adapters, contact the \nadapter manufacturer to obtain updated Windows drivers. Try disabling sync \nnegotiation in the SCSI BIOS, checking the cabling and the SCSI IDs of each \ndevice, and confirming proper termination.
6. For integrated device electronics \n(IDE) devices, define the onboard IDE port as Primary only. Also, check each IDE \ndevice for the proper master/subordinate/stand-alone setting. Try removing all \nIDE devices except for hard disks. If the message appears during an installation \nof Windows, make sure that the computer and all installed peripherals are listed \nin the Microsoft Windows Marketplace Tested Products List.

  • some recent CPython changes,
    • \n
  • the new PyPy 1.2 release,
    • \n
  • crypto support and Debian packaging for IronPython,
    • \n
  • the PyWeek game programming contest,

  • upcoming conference plans,
    • \n
  • and upcoming podcast plans.
    • \n
\n","hostid":121,"series":38,"explicit":1,"license":"CC-BY-NC-SA","tags":"News,CPython,IronPython,PyWeek","version":0,"downloads":1569,"valid":1}, {"id":546,"date":"2010-06-03","title":"Shot of Hack - Changing the time offset of a series of photos","duration":399,"summary":"Ken discusses how to modify image metadata from the command line using exiv2","notes":"The problem: You have a series of photos where the time is offset from the correct time but is still correct in relation to each other.

\n

Here are a few of the times that I have needed to do this: - Changing the battery on my camera switched to a default date. - I wanted to synchronize the time on my camera to a GPS track so the photos matched the timestamped coordinates. - At a family event where images from different cameras were added together.

\n

You can do edit the timestamp using a GUI and many photo manipulation applications like the GIMP support metadata editing. For example on KDE:

\n
gwenview -> plugins -> images -> metadata -> edit EXIF
\n

The problem is that this gets tiresome after a few images, and anyway the times are correct in relation to each other - I just need to add or subtract a time correction to them en masse.

\n

The answer: exiv2 - Image metadata manipulation tool. It is a program to read and write Exif, IPTC and XMP image metadata and image comments.

\n
user@pc:~$ exiv2 *.jpg\nFile name       : test.jpg\nFile size       : 323818 Bytes\nMIME type       : image/jpeg\nImage size      : 1280 x 960\nCamera make     : FUJIFILM\nCamera model    : MX-1200\nImage timestamp : 2008:12:07 15:12:59\nImage number    :\nExposure time   : 1/64 s\nAperture        : F4.5\nExposure bias   : 0 EV\nFlash           : Fired\nFlash bias      :\nFocal length    : 5.8 mm\nSubject distance:\nISO speed       : 160\nExposure mode   : Auto\nMetering mode   : Multi-segment\nMacro mode      :\nImage quality   :\nExif Resolution : 1280 x 960\nWhite balance   :\nThumbnail       : image/jpeg, 5950 Bytes\nCopyright       :\nExif comment    :
\n

The trick is to pick a image where you can that figure out what the time was and work out the time offset. In my case I needed to adjust the date forward by six months and four days while changing the time back by seven hours. I used the command exiv2 -O 6 -D 4 -a -7 *.jpg

\n
-a time\n    Time adjustment in the format [-]HH[:MM[:SS]].\n    This option is only used with the 'adjust' action. Examples:\n        1 adds one hour,\n        1:01 adds one hour and one minute,\n        -0:00:30 subtracts 30 seconds.\n-Y yrs\n    Time adjustment by a positive or negative number of years, for the 'adjust' action.\n-O mon\n    Time adjustment by a positive or negative number of months, for the 'adjust' action.\n-D day\n    Time adjustment by a positive or negative number of days, for the 'adjust' action.
\n

When we run this we can see that the timestamp has now changed.

\n
user@pc:~$ exiv2 *.jpg | grep timestamp\nImage timestamp : 2009:06:11 08:12:59
\n

That's it. Remember this is the end of the conversation - to give feedback you can either record a show for the HPR network and email it to admin@hackerpublicradio.org or write it on a post-it note and attach it to the windscreen of Dave Yates's car as he's recording his next show.

Setup

\n

Sets up a real email address eg real@example.com and another one for spam eg: spam@example.com

\n

Per Company emails

\n

A rule is set so that any messages that is not destined for a real/configured email address goes to spam@example.com.

\n

Give companies unique email addresses on your domain, and set up a rule to redirect that to the real address if the domain that is sending is the same as the prefix.

\n

For example hackerpublicradio.org@example.org coming from admin@hackerpublicradio.org would be sent to real@example.com. While hackerpublicradio.org@example.org coming from spammer@spammer.org would be sent to spam@example.com.

\n

Throwaway emails

\n

someword.x.user@spamgourmet.com where someword is a word you have never used before, x (optional) is the number of email messages you want to receive at this address (up to 20, and the number 3 will be used if you leave it out), and user is your username.

For My hacker Public Radio spot.
Recently, I had a chance to review about 30 years of my investing and savings.
Being a live long member of the save 10% club and having been debt free for a number years I thought I needed a review.

\n

Having been in the military I had picked almost all the wrong kinds of things to invest in in the pre-internet era that one could think of.
A few years ago when Ron Paul was running for President.
I stumbled upon his web site.
Having shared many views with Mr. Paul and him being a small town doctor from Texas.  I was very interested in what he invested in.
I read that he had about 50% of his assets in hard assets like Gold Coins and the rest T bills.
Of course he was debt free and owned his home and land out right as well. 

\n

I use Etrade and I am slowy moving the mistakes of the Army.
Its just hard to get in touch with folks that deal with paper.

\n

The reason I like Etrade so much is that they show the total loss or gain each investment right away.  No guessing you can see it.
You also pay as you go with them and it is very clear what you have to pay in total fee’s.

\n

I like the treasury direct site as well.

\n

But what really interested me.
Is what is coming.  And this is the Hacker part of that really says wow.
I have been a user of pay pal for a long time.
I have a German and American account with them and find its a great way to move dollars to euros with out a lot of over the top fees.
Most people do not think about having two types of money but I assure you the dollar is not worth very much today vs. the Euro.
Which is great for American Jobs. 
Being a Pay Pal user I a saw this Microplace site they have.
I used my pay pal ID and it worked.
There was no tricks or anything. 
You make a small loan to women in south texas or coco farms in the islands and they really pay you back.
I have done it for a few years and it made feel a lot better about sharing my money and getting a fair return.

\n

I also look into owning a share of Windmill or truck or locomotive but the incoming costs are pretty high.  About 15K to starting in Germany to own a share of ship or locomotive.  I like this because its a set investment a train that works in the Hamburg harbor and its there you can go and see it on your web cam and see it work.  It pays back your entire principle over the 30 years of its life and it pays a share of the profit for that year.  I have not found very many American investments like that.  But have heard that some Oil trusts can do that.  Can I have a web cam of it working would be a qualifying point for me. 

\n

Well enjoy and thank about it.
Keep it simple if you do save and watch fee’s.
The younger you start the easier it is.
And do not borrow money with credit cards or by car with credit or buy home unless you put 20% down.
Would be the only other advice.
I read book one time about wealthy barber and another about a guy who saved three years living expenses.
I used much from both. 
The one that really changed my life was when I had the living expenses worked out.
It changed how I felt about my Boss and what I would be willing do a lot. 
The spirit to take chance also came from that.

\n

In any case I am off enjoy and be safe.

Many people only think about it from the fans perspective, without realizing the different steps it's taken to get to them. ThistleWeb talks about the current copyright cartel thinking in how it affects musicians. The same people who claim to speak on behalf of artists, lobby to enshrine laws supposedly for the artists. He talks through the process of starting a band and how often these laws crop up forcing the next generation of musicians to spend a LOT of money to stay legal, or be criminalized. Staying legal means coughing up to maintain the status quo.

\n

He ends with a brief comparison of how things can work under a Creative Commons license.

\n

He forgot to mention the parallels with the Musicians Guild in Discworld by Terry Pratchett, who send the assassins in to deal with people who think they can play music without being paid members of the Guild.

    Intro: Most of us grow into our computer knowledge gradually, starting because of an innate curiosity, figuring things out through trial and error, desiring to accomplish certain tasks, or just possessing a genetic predisposition to geekiness.  But what would it be like as a non-geek to come from a non-technical background and be thrown into “the deep end of the pool,” challenging yourself to learn as much as you could from scratch, and to learn it all as quickly as you could?  In Curbuntu’s first interview with “Baylee Juran,” a career public-school teacher (and self-described technological “dinosaur”), Baylee shares what motivated her to lay aside a comfortable, if frustrating, teaching paradigm in the hope of evolving into a 21st-Century instructor.  (Note: No cockatiels were harmed in the recording of this interview.)

    \nWput is a command-line ftp-client that looks like wget but instead of downloading, uploads files or whole directories to remote ftp-servers.\n

    \n

    Main Features

    \n
      \n
    • wget-like interface
      • \n
    • TLS-encryption
      • \n
    • resuming
      • \n
    • speed-limit
      • \n
    • time-stamping (compares local and remote dates)
      • \n\n
    • proxy-support (socks5, http)
      • \n
    • i18n
      • \n
    • windows-compatibility
      • \n
    \n\n

    Wput is a free utility that is able to upload files to a\nftp-server.

    \n\n

    Wput is non−interactive and background-capable. It\ncan upload files or whole directories and is meant to be a\nrobust client even for unstable connections and will\ntherefore retry to upload a file, if the connection\nbroke.

    \n\n

    Wput supports resuming, so it automatically continues\nuploading from the point where the previous upload stopped,\nmeaning that you can kill Wput anytime and it will (if the\nremote ftp−server supports this, being most likely the\ncase) finish the partial uploaded file.

    \n\n

    Wput supports connections through proxies, allowing you\nto use it in an environment that can access the internet\nonly via a proxy or to provide anonymity by hiding your\nip−address to the server. For SOCKSv5−proxies\nWput supports also listening mode, allowing you to use\nport-mode ftp through a proxy (useful if the remote ftp is\nbehind a firewall or a gateway).

    \n\n

    Wput supports timestamping, so it will (in the ideal case\nand if timestamping is enabled) only upload files, that are\nnewer than the remote-file.

    \n\n

    The upload-rate of Wput can be restricted, so that Wput\nwon’t eat all available bandwidth.

    Syndicates Shows

    \n\n

    \nI'm running into some difficulties with how best to address syndicated shows and I'd appreciate your feedback.\n

    \n

    \nThe background is that I'm trying to specify scheduling rules (https://hackerpublicradio.org/calendar.php) trying to been fair to everyone but also with a view to automating the task. I've taken the view that shows produced for HPR will get priority in the schedule before syndicated shows. This brings up the question of what is a syndicated shows.\n

    \n

    \nIf a show is posted to a RSS feed before been posted to HPR then it would be considered to be a syndicated show. However we have had resubmission of a series that was on a podcast that faded so probably no one heard them. Are theses shows now syndicated or do I schedule them as HPR shows ?\n

    \n

    \nWe have also had submissions from a host that posts to the HPR FTP server and their own feed at the same time. Because of the delay in HPR scheduling they come out later than their own RSS feed. So are these also now syndicated ?\n

    \n

    \nAfter hearing 635 Dismal Science:: Cloudy Predictions I was reminded that the speech Freedom In the Cloud: Software Freedom, Privacy, and Security for Web 2.0 and Cloud Computing by A Speech given by Eben Moglen at a meeting of the Internet Society's New York branch on Feb 5, 2010 would be ideal for HPR. Then Fifty OneFifty emailed to say \"I noticed there hadn't been any recordings from LUG meetings in a while. I thought you might want to ask for submissions where meetings or talks (from various fests) are already recorded.\" With the scheduling rules as they are at the moment, the syndicated don't ever get played.\n

    \n

    \n

    \nOn the other side I've had comments that the \"Flood Gates\" had been opened on the HPR feed.\n

    \n

    \nSo thinking about it I was thinking of reserving Tuesday and Thursday for syndicated shows, LUG talks, Speeches and the like.\n\nFeedback to the mailing list https://hackerpublicradio.org/maillist\n

    Thoughts.

    \n
  • The router restarts itself when you flash the firmware, which is nice.
    • \n
  • If you change the IP of the router you may have to disconnect and reconnect the network through linux to force it to update the new IP address. Don’t forget like I did!
    \n
    • \n
  • To set up a Wii via Wi-Fi you need to set the router up as ‘Ad-Hoc’ else it doesn’t seem to show in the Wii menu.
    • \n
  • I had problems with my previous router being 192.168.1.1 and the DSL being 192.168.0.1 making me hard reset and set the details back up. Might be unrelated to this, however changing the IP to 192.168.10.1 for the router and keeping 192.168.0.1 for the DSL resolved this problem.
    • \n
  • It was pretty damn simple! At least a lot simple and faster then installing windows!
    • \n
  • Total time isn’t too long, but I’d recommend having a second router on hand (if you can) to keep internet access in case things go hairy!

    Kurt Vonnegut

    \nborn after WWI, died in 2007. Served in WW2\nwrote Slaughterhouse-five the year Neil Armstrong landed on the moon.\npostmodernism (started after WW2), and I guess continues today, since Thomas Pynchon is still alive.\n

    \n

    \nIn short, postmodernist literature takes everything with a large grain of salt, and the stories are often a commentary on the story itself. (like a recursive function) (e.g.: \"That was I. That was me. That was the author of this book.\")\n

    \n

    Slaughterhouse-five

    \n

    \n\n
      \n
    • About an emaciated, fatalistic, and ill-trained soldier named Billy Pilgrim in WW2, who is once compared to a broken kite.\n
    • The narrative is nonlinear, but it follows some of Billy's experiences in Germany, and then getting caught and shipped to Dresden for community work, where they stay in an old meat-packing house called \"Schlachtof-funf\"\n
    • When Dresden is bombed, most are killed, but the American soldiers survived and experienced the total destruction of the city\n
    • Billy then returns to the US, where he becomes and optometrist, and marries an undesirable obese woman, whose father has a lot of money, and they have children.\n
    • He suffers head injuries in a plane crash (of which he is the only survivor) and starts thinking he has made a connection with the alien people of Tralfamadore, with whom he has traveled in time and has seen all that will happen in the future.\n
    • He starts giving radio talks and speeches about the nature of time and flying saucers, and he dies shot at one of these events in Chicago.\n
    \n

    Quotes:

    \n

    \nAll this happened, more or less. The war parts, anyway, are pretty much true. One guy I knew really was shot in Dresden for taking a teapot that wasn't his.\n

    \nAs an Earthling, I had to believe whatever clocks said -- and calendars.\n

    \nAll this responsibility at such an early age made her a bitchy flibbertigibbet.\n

    \nThe gun made a ripping sound like the opening of the zipper on the fly of God Almighty\n

    \n\"There's more to life than what you read in books,\" said Weary.\n

    \nLike so many Americans, she was trying to construct a life that made sense from things she found in gift shops.\n

    \nOne scout hung his head, let spit fall from his lips. The other did the same. They studied the intinitesimal effects of spit on snow and history.\n

    \nNow they were dying in the snow, feeling nothing, turning the snow to the color of raspberry sorbet.\n

    \nRosewater told a psychiatrist: \"I think you guys are going to have to come up with a lot of wonderful new lies, or people just aren't going to want to go on living.\"\n

    \nSo they were trying to re-invent themselves and their universe. Science fiction was a big help.\n

    \n\"That's the attractive thing about war,\" said Rosewater. \"Absolutely everybody gets a little something.\"\n

    \n\"I'm afraid I don't read as much as I ought to.\" said Maggie.
    \n\"We're all afraid of something,\" Trout replied. \"I'm afraid of cancer and rats and Doverman pinschers\"\n

    \nAnd then Russians came on motorcycles, and they arrested everybody but the horses.\n

    \nSo it goes. (appears 106 times in the novel)\n

    \nThere used to be a dog named Spot, but he died. So it goes.
    \nThe champagne was dead. So it goes.
    \nThe water was dead. So it goes. Air was trying to get out of that dead water. Bubbles were clinging to the walls of the glass, too weak to climb out.\n

    Erlang:

    \n

    based on a one day training session with Kevin Smith @kevsmith\ndesigned by Ericsson in 1986 to support big fault-tolerant applications, released open source in 1998. Stands for Ericsson Language.\n

    \n\n

    multicore

    \n
      \n
    • main feature: great support for concurrency (doing multiple things at the same time)\n
        \n
      • Though I'm not an expert, languages such as Java and Python struggle to efficiently use machines that have tens or hundreds of cores.\n
      • Erlang has these lightweight processes with minimal overhead, allowing the rapid creation of hundreds of thousands of these processes. These processes have no shared state. They know nothing about each other. They communicate through asynchronous message passing. each process has a mailbox, which it checks to see if it has the message it wants, and then deletes it after it's consumed. Very much how we would ideally check our own email inboxes.\n
      \n
    • to start one of these you just call spawn(Fun), which returns a pid (process ID)\n
    \n\n

    functional

    \n
      \n
    • Immutable variables\n
        \n
      • assignment only\n
      \n
    • functions are first class citizens, that can be used like any other data, like an integer.\n
    • this basically replaces the need for objects in OO languages\n

      \n
    \n

    proven

    \n
      \n
    • CouchDB, Membase, Riak, RabbitMQ\n
    \n

    \n

    Similarities:

    \n

    \n

    \nAll this happened, more or less.\nspawn(Module, Function, Args) -> pid\n

    \n

    \nPack a lot of meaning in a few lines: He said that everything there was to know about life was in The Brothers Karamazov, by Feodor Dostoevsky. \"But that isn't enough anymore.\"\n

    \n
    \n1> A = [1,2,3,4,5].\n\n[1,2,3,4,5]\n\n2> [X || X <- A, X rem 2 == 0].\n\n[2, 4]\n
    \n

    \nimmutable variables - Billy Pilgrim - we find out more about him (and in the process ourselves). This consistency allows us to depend on the narrator more, as we depend on an erlang program more that state will not change in the middle.\n

    \n

    \nfunctional - jumping in history, future, and dreams, which can all live on their own and can be used independent of one another.\n

    \n

    \n\"He is in a constant stage fright, he says, because he never knows what part of his life he's going to have to act in next.\"\nthat's like Inboxes and message passing in Erlang.\n

    \n

    \nSo it goes. The ending of an Erlang line could be , ; or .\n

    \nHistory . . .
    \nMy start in 1982 with a BBC Micro Computer.\nOn using a 1977 business machine by Real Time Computer Systems, Crewe, UK.\nGary Kildall's CP/M operating system with four, linked, 7 floppy disk drives.\nMoving to the PC about 1988 and becoming a Microsoft operating system user.\nUsing the PC for educational material and for musical arrangements.\nThe main pieces of software used for the music Sibelius and Band-In-A-Box.\nSome web designing using Macromedia Dreamweaver.\n

    \n

    \nTowards Linux . . .
    \nAwareness of Linux about 2000 first 'proper' distro SuSE; (six CDs to install!)\nPoor press for Linux in the past and not much better now.\nModern distros offer close to the full solution for the average user.\nRetailers still telling customers that Linux is difficult and should be avoided.\nMy trials of most of the available distros and awareness of Wine as a solution to using Windows-based software.\nSome limited success with early copies of Sibelius, Band-In-A-Box and Dreamweaver.\nDiscovery of Ubuntu 6.06 and the installation on my Desktops and Laptops.\nMaintainance of a Laptop as a dual-boot machine with Windows XP.\nLinux used for all my work; only very rarely using the Windows partition.\nBrief trial of Virtualbox initially, with not too much success.\nCurrently, Ubuntu 10.10 on all machines and the 'ditching' the dual-boot.\nLook at Virtualbox again, thanks to the recent Hacker Public Radio Podcast by arfab (hpr-0618) on installing XP in Virtualbox. (Thanks arfab.)\nVirtualbox on all my machines now running my 'essential' Windows software.\n

    \n

    \nPracticing . . .
    \nNeed for regular practise using a variety of techniques (improvisation, scales, etc,).\nGood use of Band-In-A-Box as a practice aid.\nMost backing tracks in the form of a simple piano, bass and drums rhythm section.\nGood aid to meet the needs of students at various stages of ability.\nBacking tracks tailored to support each musical instrument in a musical ensemble.\n

    \n

    \nWhere Are We Now . . .
    \nAwareness of current developments in support of the musical requirement.\nStill can't say to my colleagues - Yes, Linux is now the complete solution.\n

    \nIn episode 5X18 of the Bad Apples podcast, Klaatu challenged me to create my own podcast \nexplaining my Python version of his bash script. His bash script created a list of\nfiles that matched a file name pattern, then read the first line from each of those files\nand wrote that to an output file. My Python program does exactly the same thing, but in Python.
    \nHere is the body of that program with the comments stripped out:

    \n
    \n#!/usr/bin/python\nimport glob\noutfile = open(\"toc.output\", \"w\")\nfor filename in glob.glob(\"*.txt\"):\n    outfile.write(open(filename).readline())\n
    \n

    \nThe above text can be used to follow along with the audio of the podcast. Here is the English explanation \nversion of the above program:
    \n

      \n
    • Tell the system the rest of the text in the file should interpreted by Python
      • \n
    • Import the glob module, which is one of the library modules that comes with Python
      • \n
    • Create a new file object called \"toc.output\" that we can write to
      • \n
    • Iterate over the list of files that match the pattern \"*.txt\" created by the glob function, and assign each matching file in turn to the filename variable
      • \n
    • Open each filename, read the first line from the file and write it to our previously opened output file.
      • \n
    \n\nIt's not shown above, but each matching filename that we open is closed at the end of the looping construct. \nIn addtion, the output file is also closed at the end of the programs execution.\n
    \nHopefully you enjoyed the podcast!\n

    Scheduling Rules update

    \n

    Shows will be released based on the following rules that gives content produced for HPR priority, while avoiding having any one host/series repeated in a week. Hosts are encouraged to release their shows on other feeds after uploading them to HPR.

    \n

    \n

      \n
    1. Time critical
      \n Where the host has requested a show to be posted at a particular time or that the show contains newsworthy information.
      2. \n
    2. Scheduled Slots
      \n Where a host has been assigned a regular day to release a show.
      3. \n
    3. New Hosts
      \n In order to encourage new hosts we will prioritize shows submitted from new hosts so they can experience the excitment of podcasting.
      4. \n
    4. HPR Content on a First in First Out basis.
      5. \n
    \n

    \n

    Syndicated shows will be released on their own scheduled slot following the same rules as above.

    \n\n

    HPR Stickers

    \n

    \n\n

    \n

    \nHot off the press !
    \nThe HPR stickers have been distributed to our Global distribution network in North America, Europe and Australia.
    \nFor anyone else on this who wants them, now is the time to ask; before they all get handed out at the first couple of Linux fests. They're free as in beer btw.
    \nWe're also sending stickers out to the other podcasters who promoted HPR in the past.\n

    \n\n

    Audio Book Club

    \n

    \nSeveral of the HPR contributors in the IRC channel have formed the beginning of an audio-book club. We'll be doing reviews which include spoilers, so I was wondering if you could announce our first audio-book title in case anyone wanted to listen to it before we spoiled it on them. We're hoping this will become a(n ir)regular show for HPR, but we'll see how the first one goes. All audio-books that we review will be free (as in beer) and easily available, so the barrier to entry for the listeners and participants will just be the time involved in listening to the audio. The first audio book is a short one. It runs about 3.5 hours total, and I can tell you it is a very good book which will appeal to both science fiction fans and political critics alike. \n

    \n

    \nThe book is Badge Of Infamy by Lester Del Rey and read by Steven Wilson. It is available from podiobooks.com. The direct url is\nhttps://www.podiobooks.com/title/badge-of-infamy.\n

    \n

    \nFrom podiobooks.com: \"Daniel Feldman was a doctor once. He made the mistake of saving a friend's life in violation of Medical Lobby rules. Now, he's a pariah, shunned by all, forbidden to touch another patient. But things are more loose on Mars. There, Doc Feldman is welcomed by the colonists, even as he's hunted by the authorities. But, when he discovers a Martian plague may soon wipe out humanity on two planets, the authorities begin hunting him for a different reason altogether.\"\n

    \n

    \nWe'll be announcing the next book at the end of our first show.\n

    \n\n\n

    Site improvements

    \n
      \n
    • Each hosts have their own folder ie: hackerpublicradio.org/droops/\n
    • Vimeo Group https://vimeo.com/channels/hpr\n
    • Site redesign more up-to-date looking.\n
    • All comments and posts need a rel=nofollow tag on links.\n
    • All the RSS feed needs to be put in the address bar\n
    • Each episode title link should link to the individual show page\n
    • A separate link/graphic should play the audio, maybe have a built in player and a download link.\n
    • Each episode should have a unique url with the shows title in it, ie hackerpublicradio.org/geocaching_with_droops/ \n
    • We need more of a call to action about recording a show, its kinda hidden.\n
    • The total comment viewer needs to link to the episode page, so that people can see all of the comments about the episode.\n
    • A way to upload our episodes and automate everything.\n
    • We also need the ability for the hosts to add episodes of hpr and other shows to a \"Select\" RSS feed. This way, when we find something super cool that someone else recorded, we can share it with the community.\n
    \n\n

    News from the Admin Channel

    \n

    HPR is been blocked by some companies because they can filter the find the word hacker - money well spent. During the spam fest, HPR got listed on sites as a source of malware. I've been contacting the sites but each blames the next one for the listing and the trail runs cold.\n

    \n

    I registered Hobby Public Radio but cPanel doesn't seem to have a way to have HackerPublicRadio and HobbyPublicRadio served from the same directory.

    \n

    \nQuestion: Off the shelf or Self Build ?\n

      \n
    • Can we make a HPR site using standard Wordpress plugins ?\n
        \n
      • User account management\n
      • Podcast plugins\n
      • Released according to a schedule \n
      \n
    • email from the server is broken through cPanel and this is delaying up automation \n
    • Any PHP programmers want to help\n
    • Proposal to make droops, finux, klaatu admins\n
    • Still no update on the Ice Cast server\n

    What web resources (instructional sites, podcasts, video tutorials) and dead-tree resources have you found helpful in learning Linux, programming, and F/LOSS software?  In the tradition of our standard contributor podcasts (like “How I Got Started with Linux” or “My First Computer”), Curbuntu proposes an ongoing category in which we share these learning resources with each other.

I was contacted by Karen from the Free as in Freedom oggcast (https://www.faif.us/) to tell me that klaatu had been arrested by the department of immigration while urban camping in some corporate head quarters in Cupertino. She wasn't allowed to say much apart from that the department of homeland security is now involved as well and have confiscated his laptop and are holding him at an undisclosed location.

    After his outspoken criticism of accessibility in Ubuntu, Jonathan Nadeau has become the standard bearer for accessibility on the FLOSS desktop. In his interview with the KDE spokesperson Aaron Seigo, Jonathan didn't ask any questions about accessibility. I was expecting to hear what accessibility improvements are in the pipeline for KDE.\n

    \n

    When I contacted Jonathan about it he immediately replied saying that they did talk about accessibility. He didn't add it as the show was running too long and that he might release it as a separate podcast. I floated the idea of releasing it on HPR and he was kind enough to mail me the segment.\n

    \nAfter years of using Unix, Mac, and Windows I finally converted my two Windows computers to Linux for real.
    \nThe journey into Linux started with not being successful at writing a startup script for Linux. A few years later I discovered some Linux love when writing a driver that would make the keyboard LED lights blink the morse code of the letters being typed. A year ago I did a few virtual Linux installations (archLinux, Debian) in VirtualBox to test out some Cloud Computing stuff. \nBefore Christmas 2010, I was considering contributing to the KDE project and installed Kubuntu as well as Ubuntu.
    \nThis year, because I am going to the LinuxFest NorthWest (and I am going to have a table there for HackerPublicRadio) I had to install Linux on my old Windows Laptop. I also converted my Samsung Q1 Ultra Tablet computer from WindowsXP to Ubuntu.
    \nBoth conversions were successful, but a few problems had to be solved for which https://answers.launchpad.net/ubuntu is a great place to go and find or get answers.\n

Originally name S.H.I.T.cast (Student Hacker Information Technology podcast), it was aimed at a lower level of audience and was more about having fun then getting anything technical across.\nThere are two hosts to the podcast, Matthew Hughes and Thomas Mackenzie.\nMatthew Hughes is an Ethical Hacking student at a British University and is the leader developer of SecurityBSD.co.uk. He is known on the podcast for his random facts and amazing shoot downs towards Tom.\nThomas Mackenzie is a student studying the same course at the same University as Matt. He is the co-developer of upsploit.com and works part-time from randomstorm.com. \n

    \nMy thanks to Pokey and ClaudioM for their kind comments on my first show. \n

    \n

    \nRecording . . .
    \nHow I record the show and use Linux in support of my jazz activities and work-flow.
    \nSet up and Gear:
    \nMain microphone - Behringer USB Condenser Microphone C-1U with boom mike stand and 'pop' screen.
    \nSennheiser e815S with a Tascam US-100 Audio Interface or Zoom H4n Recorder.
    \nAudio Capture:
    \nBehringer USB mike straight into Audacity on an EeePC.
    \n(Klaatu's config file is at https://www.thebadapples.info/eastereggs/audacity.cfg.zip)\n

    \n

    \nProcessing . . .
    \nLaptops Asus EeePC 1005HA and a Sony Vaio VGN-BX297.
    \nAll recordings saved as WAV or FLAC files initially.
    \nSpoken part of the show is scripted and each segment recorded separately.
    \nAssembly of segments and audio in Audacity, with adjustments, fades and overlaps, etc.
    \nExported and mixed down into composite, sterio, MP3 file.
    \n

    \n

    \nMusic Production . . .
    \nMusic writing, arranging and composing: Band-In-A-Box 2009 and Sibelius 5 as there is no suitable Linux equivalents.
    \nUsing Virtualbox with Windows XP.
    \nBand-In-A-Box use of sampled sounds for the backing voices.
    \n

    \n

    \nUse of Band-In-A-Box and Sibelius. I just wish there was the equivalent software the Linux to do this kind of thing I would move there 'in a flash' if I could find some.\n

    \n

    \nOther Activities . . .
    \nProblem with keeping files up to date when using multiple machines.
    \nUse of 'Dropbox' is my solution.
    \nFolders moved from 'Dropbox' to large 1TB external drive when projects are complete.
    \n

    \n

    \nNext time . . .
    \nLinux software in the production of websites and other uses.
    \n

    \n

    \nMy website and Blog . . .\nAt 'www.tonydenton.com' and I am on Twitter as 'tonydenton.'
    \nMy Identica name is 'Bariman' and I am on IRC, also as 'Bariman.'

    Concerns:
    \n 1) package burn out - will it get to the point where only either large distros or commercial distros have large repos due to the effort involved?
    \n 2) I've lost track of the number of times i've heard from people 'our distro doesn't have enough manpower to package ...'
    \n wouldn't it be helpful to not have to use our limited manpower in building redundant packages?
    \n 3) in 10 (or less) years when non-technical people take over at Redhat/Ubuntu/other large distro, will they use the package system as a club to beat the other distros with? I'm not sure how, but where money is involved, you can feel assured it _will_ happen.
    \n 4) current state of packaging systems in linux is like sound systems were 10 yrs ago.
    \n remember esd vs arts vs vs ...? each desktop environment had its own system. sound in linux was painful and a complete joke. it still has a ways to go but it's _SO_ much better now that it was. does anyone want to go back to that?
    \n pulseaudio isn't perfect but it's so much better than what we had before. and it's ONE system!
    \n can you image if printing and authentication were like the packaging systems? image if everyone had their own printing system instead of CUPs? imagine if there was no pam.d?
    \n 5) I believe packaging systems are NOT about choice. the exact opposite. it's about vendor lockin and NIH.
    \n (we'll do it OUR way because we can do it better or the 'proper' way. "so-and-so does blah, which is
    \n completely stupid")
    \n choice is being able to write a script in php,perl,python,bash,csh,... on the SAME system.
    \n that's choice
    \n because I can CHOOSE. If I have a debian box I can't choose to use RPM or ebuilds, same for those other systems.
    \n of the systems I've used: deb, rpm, rpm5, portage, (and tarballs if you count linuxfromscratch)
    \n and the managers I've used: yum, urpmi, smart, kpackagekit, synaptic, apt-get, emerge
    \n each system has little features the others don't. but there is nothing that one system has that couldn't be added to the others.

    \n

    Taking place AUGUST 13 & 14, FARNHAM MALTINGS, UK

    \n

    \nOggCamp 11 is a two-day unconference where technology enthusiasts come\ntogether to exchange knowledge on a wide range of topics from Linux\nand open source software to building home automation systems. Now in\nits third year, the event is steadily growing and attracting\ninteresting speakers from all over the UK, the rest of Europe and even\nthe US. Since OggCamp is an unconference, speaking schedules are set\non the first day and everyone is free to propose a talk themselves.\nYou are of course free to come along and just listen to other people's\ntalks but we strongly encourage everyone to take part and talk on\nsomething they are passionate about in technology. OggCamp was first\norganised by the combined forces of the Linux Outlaws and the Ubuntu UK Podcast as a filler\nevent after the last\nLugRadio Live was decided to be a one-day only event.\n

    Tunnelling over DNS inquires
    \nFinux gave a number of talks (most recently at BSides London) about how you can use DNS tunnelling to bypass some of the usual protocols to access online systems that would not let you access them without being subscribed.

    What is Slackermedia?

    \n

    Slackermedia is documentation providing the information a user will need to create a full multimedia studio from a Slackware base install. Inspired by Linux-From-Scratch, it is intended to be a \"distro from text\"; a do-it-yourself Linux studio beginning with installing Slackware and ending with what we will call \"Slackermedia\" with all the custom-compiled and configuration of only the best in multimedia content creation tools that Linux offers and the user requires to achieve their artistic goals.

    \n \n

    Slackermedia is not a distribution, and merely builds upon Slackware proper. Slackermedia is not a laundry list of multimedia apps that are half-finished, it is not a blueprint for how to make your distribution contain lots of multimedia apps you'll never use, it is not a series of brainless install scripts. It is a series of tutorials on what a user will need to understand, and how they can go about installing or compiling or configuring important tools like jackd, software synths, soundfonts, gimp brushes, fonts, individual apps, backends like ffmpeg and mencoder, and much more.

    \n \n

    NOTE: Slackermedia is currently optimized for Slackware 13.1. A 13.37 version with the 2.6.38.4 kernel is in progress.

    CCHits.net is a site promoting and featuring Creative Commons licensed music and the podcasts that play them. The site was designed with more than just this in mind. Here are some of the highlights

    \n
      \n
    • \n

      Encourage and Discover Great Music

      \n

      There's a lot of great Creative Commons Licensed Music out there, and not enough people know just what you can get hold of! To help ease the burdon of this issue, there are three things that we do:

      \n
        \n
      • By linking directly to artist's home sites rather than to our own holding pages for artists, we ensure that the artists get maximum exposure for their own material, without having to update our site when their own information changes!
        • \n
      • By linking to the source of the individual track, gives listeners a greater awareness of music sources, which hopefully should increase the exposure for sites who promote and list Creative Commons licensed music.
        • \n
      • By linking to podcasts which play Creative Commons licensed music, we give listeners the opportunity to find other shows that play the music they like - ultimately giving listeners a greater fountain of great music to select from, and hopefully giving them the opportunity to discover new artists and genres to add to their personal list of favourites.
        • \n
      \n
      • \n
    • \n

      Support Communities

      \n

      An attendor at various social groups, the original author of the code which drives cchits.net was unable to provide consistent, suitable background music for events he was involved in organising or just attending. This site was originally designed to find tracks which are generally acceptable for public play, and are available under a suitable license for public performance (which Creative Commons music should be!) By asking all submitters of music to identify the license under which the tracks are made available, as well as selecting whether tracks may not be suitable for work or family listening, it should be possible (once the code is in-place) to request from the site a suitable selection of music for playback at venues such as hackspaces, youth centres, or even just hold music for a business. Note that this site is not being created to build a re-licensing business, but instead to promote awareness of great music - there are other, better sites, that can advise and assist in the selection of Creative Commons music which are suitable for your business endeavour, but if you just want something for backing music for an hour or a whole day, this site might be (eventually!) just the thing for you.

      \n
      • \n

      Create Podcasts and Improve Coding Techniques

      \n

      At the time of writing, cchits.net is the work of one person. For several months, Jon \"The Nice Guy\" Spriggs had been considering starting a podcast, however, he's not exactly known for finishing projects! By making a system which is automated enough to create a daily podcast, a weekly podcast and a monthly podcast, playing music that he likes to hear, he thought it might encourage him to stick to it - especially when there are other amazing goals (see above) which come out as a side benefit. He normally has described himself as a writer of \"bad PHP code\", and each project he starts improves the techniques he has learned.

      \n

      In this instance, CCHits.net has introduced Jon to the concept of writing an API that works, a system of remote execution of code, the generation of synthesized speech and the generation of an audio track, entirely in code! Never being shy of criticism from the community, especially where code is concerned, the code has all been released under a license which encourages reuse and requires the code is re-released under the same license.

      \n
      • \n
    \n\n

    If you already podcast, and you play Creative Commons Licesed Music on a regular basis, you might be interested in using the API on this site to track the music that people who listen to your show have expressed an interest in. Contact show@cchits.net to find out more

If approved all shows after\nthat time will be by default CC-BY-SA unless indicated in the show\nnotes. Further, I would then contact everyone that has hosted so far\nasking if we can relisence their show(s) as CC-BY-SA.\n\nThis is entirely up to the community so please use the mail list you\nvoice your opinion. Even a one liner is fine.\n\nKen.\n

    With Customs in various countries acting as Copyright Cops, using any excuse to rifle through your personal and private data not only for threats, but copyright infringement. Wouldn't it be great to have invisible ink? You can get your private data through Customs, under the scrutiny of the Copyright Cops while also being a fully cooperative model citizen.

    \n

    ThistleWeb discusses three ways to do this with the drawbacks of each.

    \n
      \n
    • Using a Cloud service of some sort to store your data on as you travel, where you upload then download after going through Customs.
      • \n
    • Using a decoy user account on your regular installed distro
      • \n
    • Using a decoy distro as a dual boot

    \n

    Harry Potter got the Marauders Map in book three, which transforms to blank parchment with a tap of the wand the words \"mischief managed\" so nobody knows it's a dynamic map of Hogwarts and it's inhabitants. Now your laptop or netbook can have the same invisible ink qualities.

    PhreakNIC is Nashville's annual hacker con. Anyone is welcome to attend. We create an environment where people who are interested in the more underground elements of technology can meet, exchange ideas and hopefully teach/learn. The primary focus is on computers and computer security, but we also cover other topics, such as radio (ham, pirate & low-power/community), SETI work, robotics, high-power rocketry, satellites, phones and phreaking, cryptography, etc. PhreakNIC is organized annually by Nashville 2600 a non-profit organization.

    \n\n

    Pre-Registration is available again through click and pledge at store.phreaknic.info. If you pre-register this year please use the \"Customize your con badge\" link in the menu to submit your visage/logo for your badge. This will be our fifteenth year and we hope you will make plans to join us.

    \n

    Tonight on GeekNights, we talk about Git: the fast version control system.

In the news, commodity face recognition, data mining, and data aggregation will do exactly what we expected and can, among other things, reveal your SSN. Adobe releases a preview of Edge.

    About the Ohio LinuxFest

    \n\n

    The Ohio LinuxFest is a grassroots conference for the GNU/Linux/Open Source Software/Free Software community that started in 2003 as a large inter-LUG meeting and has grown steadily since. It is a place for the community to gather and share information about Linux and Open Source Software.

    \n

    A large expo area adjacent to the conference rooms will feature exhibits from our sponsors as well as a large .org section from non-profit Open Source/Free Software projects.

    \n\n

    The Ohio LinuxFest welcomes people from all 50 states and international participants. We've had participants from Canada, England, Argentina, Brazil, and Australia in years past.

    Dexy is a tool for writing documents which relate to code.

You can think of Dexy as a very fancy 'make' tool with lots of document-related features and powerful filters. Dexy is open source, licensed under the MIT license.

    New Outro

    \n

    \n

    \nWe have moved providers some time ago and we need to include an advertisement for our sponsor (Lunar pages) in the outro. I have edited all the episodes that are currently in the queue to have the new outro but going forward I would appreciate it if you could switch to the new outro which can be found here https://hackerpublicradio.org/media/theme-music/outro-mono.mp3. All the versions including the original slick0 master flac, can be found at https://hackerpublicradio.org/media/theme-music/\n

    \n

    \nThe text for the outro is in the file hpr-outro-text.txt and I'd like to get a versions from every host and listener, with the idea of editing them together to have multiple versions with each line read by different people. Please submit those in high quality WAV or FLAC with spaces between each line to allow for easy editing.\n

    \n

    \nAfter recording a HPR news segment at my brother-in-law's studio he was inspired to record a intro and outro for HPR and he'd appreciate your feedback. Give the files starting in https://hackerpublicradio.org/media/theme-music/ rollercostermusic.com* a listen.\n

    \n

    \nIt would also help greatly if you could provide shownotes with your episode in html as otherwise I need to listen to your shows and make the shownotes for you which will result in a delay in your show getting posted. We are now also officially CC-BY-SA so if you are releasing your show in any other format you need to make note of that\nin your show and in the shownotes.\n

    Casting Call

    \nA while back 5150 proposed that we produce an audiobook using only HPR contributors as actors. Several people responded positively, and said they would like to participate. Well, we now have a script. It was originally written as a screenplay, so it needs a little work to make the visual bits work as audio only, but I don't think that will take too long. It's almost ready to go as is. 5150 and Integgroll have stepped up to help me make editorial and casting decisions and get other producer type stuff done.
    \n\n
    This is a casting call of sorts. We need some voice actors, but we'll also need some sound effects, and perhaps some music. I may ask people to create sound effects, and upload them to the freesound project, or just to find such sounds. I'm not sure what we'll need yet, but I'd like to know who's interested in helping out. I was considering asking the Open Source Musician's Podcast to consider doing a \"tune storm\" for some music, but I'd like to know if you guys think we should keep it all in house, or collaborate on that.
    \n\n
    The story is a SciFi/adventure that's also a lighthearted Free Software allegory, so it's a perfect fit for HPR. It will run between 50 and 80 minutes, I think, so it may be broken up into two or three episodes if it's too long for just one. I'm really not sure.
    \n\n
    The plan is to record with actors using mumble but also recording locally to get the best possible sound quality. I'll mix it all in audacity, unless someone else wants that job, or wants to do it with ardour or whatever.
    \n\n
    As is, there are 4 male roles, 3 female roles, and 6 androgynous roles. Most of the male and female roles could be swapped also to match our supply of actors. If we get more people than that, We'll add parts to make sure that everyone who's interested can participate. The protagonist and major role is female. She will have a majority of the speaking parts, thus the biggest time commitment of all the actors.
    \n\n
    If you're interested, please send me a voice sample so I can sort out the cast, or let me know what you're willing to do so I have some idea about that too. Please use my personal email address for this so that we don't clutter up the regular mailing list. pdailey03@gmail.com

    The Linux News Podcast

    \n

    \nHi fellow podcaster,
    \n
    \nI have just launched a new podcast. You know as well as I do it is hard to get the news out. I was wondering if you would please be so kind as to give it a listen. Any feedback would be appreciated. And if you like it, a mention in your podcast would be very kind. If you do, please email me so I can put a link on my website to your show.
    \n
    \nAlso if you ever need a guest on your show, please feel free to email me and let me know. If you want to know a little more about me please check out my website under About. You can also email me any questions you may have.
    \n
    \nSo what is my new podcast? The Linux News Podcast. The Linux News Podcast was designed to fill a much needed gap in audio shows covering exclusively Linux, Android, and Open Source news. The podcast aims to be relevant, accurate, fair, clear, timely, interesting and concise.
    \n
    \nThe podcast aims to be relevant by focusing on topic of interest to Linux users. I focus on such topics such as software freedom, Linux development, Open Source software, Android and mobile devises, security issues, and Linux distribution releases. Special attention is given to the top ten Linux distributions: Ubuntu, Linux Mint, Fedora, Debian, openSUSE, Arch, PCLinuxOS, Puppy Linux, Sabayon, and CentOS.
    \n
    \nThe podcast is less than 15 minutes long and is released every Tuesday and Friday evenings.
    \n\n
    \nThank you so much for your help in spreading the news.
    \n
    \nHere is the Official Press Release: https://www.prlog.org/11624836-new-linux-news-podcast.html
    \n\n\n\n\n
    \n
    \n

    \nSincerely,
    \n

    \nCheapskate Computing\n

    \n

    \nTranscriber's notes: This is probably 95%-97% accurate. I made sure to get most of the important parts, even slowing down the recording - but some stuff just did not come out clearly. We were in a very quiet room, but the Fuze's mic is not professional quality. Transcriptions marked with an asterisk * are my best guess / paraphrase. There aren't many.\n

    \n

    \nThe Carolina Free PC organization that Yancy mentions can be found here:\nhttps://sites.google.com/site/carolinafreepc/\n

    \n

    \nAudio notes: Volume normalization & removal of bias, and the noise of me pressing buttons on the Fuze was removed. There is no editing for content.\n

    \n

    \nBroam: So hi, I'm here with Yancy Smith, he was doing a...like a donation project he called the \"Scrapper Project\" here at SELF, I just wanted to ask him a couple questions about it.\n

    \n

    \nBroam: Hi Yancy.\n

    \n

    \nYancy: Hi. Um.\n

    \n

    \nBroam: So tell me about it.\n

    \n

    \nYancy: Well basically we take the time*, we take old computers from labs and computer stores, they give them to me; I recycle them to someone else. \n

    \n

    \nAnd a couple weeks ago I got clearance in talking Dave Yates, our president, said, \"can we do this here at our function\" here at SELF. and I sent out to all our club members and to most of my facebook friends, we didn't put on the general list, we just tryin' this out. We didn't have no donations this time, but some of us bought some stuff in, mainly me, brought some old stuff in, to get rid of because I don't have the room...and... it didn't turn out so well, but had a couple of bags to send with the Athens [?] team home, so they enjoyed that.\n

    \n

    \nBroam: That's cool. I have some other questions here... let's see here... um. so professional. So is this mostly you organizing this on your own, or?\n

    \n

    \nYancy: Yeah. But I'm working with the Carolina Free PC Foundation. I emailed them, they said they would be glad to take, and they emailed me back. Emailed Athens a week ago, but they didn't get my email in time, but they said next year, talk to such & such and they would know who to talk to. I'd be willing to open it to anyone.\n

    \n

    \nBroam: Okay. Is this the first year you've done this, or?\n

    \n

    \nYancy: Yeah, it's first time. It's an ad-hoc thing, our group - the club, Upstate Carolina Linux user group. ( www.uclug.org ), is a meritocracy, but I still asked for permission.\n

    \n

    \nBroam: Cool obviously crossing off a ton of questions here and who are you going to give the donated computers to? Other foundations, or?\n

    \n

    \nYancy: Mainly, um, if there had been some this year, there would have been a three-way split - who needs what parts. I found out that the Carolina [group] wanted the hard drives and certain memory sets and things, they would have gotten that. Free PCs they had certain amounts that wanted, and the rest I would have taken home or send on to someone else down the road.\n

    \n

    \nBroam: Ok. And uh, and did you look at any other projects - I know you contacted some people, but did you look at other, like, similar things that people have done on line, like, say Freegeek or Helios Initiative for anything like that, for ideas?\n

    \n

    \nYancy: Mainly it's between, um, I haven't heard of them too much; but like what I said I'm following the guidelines of the Carolina PC and some of the Athens stuff. I happen to know um, what we - I had contact with them last year and so if there's something they can use...\n

    \n

    \nBroam: Ok. You said something in the Facebook post you sent me about Linux being required by South Carolina state law. Could you explain that a little more?\n

    \n

    \nYancy: Well it's... that was a misstatement. What I was saying was that by State law requires you to send off the parts and metals stuff, not in the trash they send it off to a scrapyard - \n

    \n

    \nBroam: Oh, ok... yeah I...\n

    \n

    \nYancy: but the part about the Linux is I put Linux on there because it wipes the drive down completely and clearly because of the data retention laws, that's why\n

    \n

    \nBroam: aaaah, ok.\n

    \n

    \nYancy: see a lot of the stores, I go into a thift store, like a Goodwill or a church store, they don't really wipe down the systems they build. They don't have the [expertise]. They just wipe* a couple directories and think it's sanitized. That is a dangeorus thing to do.\n

    \n

    \nBroam: Yes, I know... (In retrospect, sounds kinda flippant, sorry. I meant to agree with him here. ed.)\n

    \n

    \nYancy: That and the license - any issues of rebuilding windows, I do that only when I have a holographic key. So it's just like even if I have a key I still put Linux on top of it, so if there's an issue with Windows, I can recover but also I still can introduce them to Linux, because games, software, photos...\n

    \n

    \nBroam: Everything is free, everything is legally transferrable.\n

    \n

    \nYancy: Yeah. Especially there's an application called Photo...photo wall or photoroom, it's sorta like Apple's album* for all your photos. It's the coolest thing.\n

    \n

    \nBroam: Cool! And I have one last question ...got any stuff for me?\n

    \n

    \nYancy: Um...\n

    \n

    \nBroam: *laughter*\n

    \n

    \nYancy: Not much left. Athens took off with all of my stuff.\n

    \n

    \nBroam: All right. Thanks a lot, Yancy. I appreciate your time.\n

    \n

    \n “Segmented downloading” is a way of getting your file by getting pieces of your file from different webservers, which mirror each other with identical content. If “bittorrent” comes to mind, then you’re following me. It is essentially using full-fledged webservers as if they were bittorrent seeds. But in order to understand why you would want to do this, you need to understand some things about old-school downloads and some things about bittorrent, before you can understand the “why,” then the “how,” of segmented downloading\n

    Who Are We

    \n

    \"The Open Society\" and the \"Tayside Linux User Group\" have long been establishing their names within the local Free and Open Source Community, as centres of support and advocacy for people from all walks of life. This September we will be showcasing some of the best that our local community has to offer.

    \n\n

    What is Software Freedom Day

    \n

    Software Freedom Day (SFD) is a worldwide celebration of Free and Open Source Software (FOSS). Our goal in this celebration is to educate the worldwide public about of the benefits of using high quality software in education, in government, at home and in business - in short, everywhere! The non-profit company Software Freedom International coordinates SFD at a global level, providing support, give-aways and a point of collaboration, but volunteer teams around the world organize the local SFD events to impact their own communities.

    \nJamey Sharp was placed on Ritalin, briefly, in fifth grade. His interests and activities have been varied ever since. Today his day job involves a computer test for attention deficit disorder, but his biggest projects have been the Portland State Aerospace Society, a student rocketry club at Portland State University; XCB, a new low-level binding to the X protocol, in the process of replacing Xlib; and Serialist, because his other projects didn’t leave him enough time to read his favorite webcomics without tool support.
    \nJamey’s interests span computer science fields including cryptography, combinatorial search, compilers, and computational complexity; systems-level programming, such as file format and network protocol implementations, Linux kernel development, and boot-loader hacking; computer architecture and its impact on software design; and functional programming, preferably in Haskell.
    \nThis interview focuses on Jamey's work on X.org, specifically the XCB project. The X protocol C-language Binding (XCB) is a replacement for Xlib featuring a small footprint, latency hiding, direct access to the protocol, improved threading support, and extensibility.

    Scheduling Shows

    \n
    \nHi Earthlings,\n\nAlong with the scheduling rules\nhttps://hackerpublicradio.org/calendar.php there is the line \"while\navoiding having any one host/series repeated in a week\". The idea was\nto allow for  someone uploading an entire series in one go and us\nhaving to schedule it. That has worked well so that the queue is full\nand that host still gets their series played fairly often, but ...\n\nAfter an event like OggCamp/ILF/OLF/SELF etc we tend to get a load of\nshows at once that are outside the traditional series concept. Some of\nthese have the \"feel of the fest\" and may go stale after a time.\n\nShould we schedule those according to the same rules meaning there\nwould be no more than one a week, or should we open the floodgates and\nhave a few weeks dedicated to post festival interviews ?\n\nDiscuss.\n

    The Flying Handbag

    \n\n

    Hello all, apologies for the lack of Weekly Rewind updates lately. Things have been crazy. I do have a rather special treat for you today instead. A podcast recorded at Barcamp Blackpool on October 15th 2011.

    \n

    Let me fill in a little background detail to this. I was in Blackpool catching up with my fellow podcaster Pete Cannon of Dick Turpin Roadshow fame. Our good friend Les Pounder of Blackpool LUG came over and asked \"are you two up for doing a podcast?\". Of course we were but had no idea what about or what the structure would be. We also didn't book a space on the barcamp schedule board. This was all very last minute. One of the talk areas at the barcamp was named The Flying Handbag after a well known Blackpool gay bar apparently. This caused much hilarity. We saw it was free and planned to record our discussion there. Upon our arrival another bloke was already there waiting to start his talk and he didn't look too impressed by our rag tag bunch.

    \n\n

    So off we wandered in search of another recording location and ended up sat on the stairs by the gents toilets in Blackpool Pleasure Beach Casino. You can hear what followed next. A rambling and fun conversation between 6 opinionated blokes, with some additional comedy value added by the really loud hand dryer noise coming from the toilets.

    \n

    Ladies and gentlemen we present.

    \nIcecast\nhttps://www.icecast.org/
    \nIcecast, the project, is a collection of programs and libraries for streaming audio over the Internet. This includes: \n

      \n
    • icecast, a program that streams audio data to listeners
      • \n
    • libshout, a library for communicating with Icecast servers
      • \n
    • IceS, a program that sends audio data to Icecast servers

    \nIDJC\nhttps://idjc.sourceforge.net/
    \n

    \n

    Internet DJ Console is a project started in March 2005 to provide a powerful yet\neasy to use source-client for individuals interested in streaming live radio shows over the\nInternet using Shoutcast or Icecast servers.

    \n

    Because of the large number of streaming applications that already existed but did little more\nthan stream a pair of audio channels or a fixed playlist, it was decided that IDJC would be the opposite\nand simulate audio hardware to cut down the expense of creating a home studio.

    \n\n

    In addition to providing a large number of show production features, this software has been written\nwith the aim of producing the best possible experience for the listeners and DJ alike. To that end features\nlike VoIP integration were conceived of from the very start resulting in the choice of Jack Audio Connection\nKit to base the audio.

    \n\n

    This has afforded IDJC audio processing capabilities that were they built in would be considered excessive. Enjoy\nintegration with powerful programs such as the well known Skype, Jack Rack (offering audio sound effects plugins),\nJamin (the powerful audio compressor/equalizer), and many more.

    \n\n

    Fortunately IDJCs power does not come at the expense of a well organized user interface, nor\nhave requests for features been permitted to diminish the application's intuitive feel yet throughout development\nthe main goals have always been that of stability and audio quality.

    The story in short

    \n\n

    At FSCONS 2010 (https://fscons.org/) I had the privilege to watch many interesting talks. Something that really peeked my interest where the talks of Knut Yrvin and Jeremiah Foster, two talented gentlemen who I was lucky to get a little private interview with as well. Their talks are available on Vimeo, and in this episode of Hacker Public Radio you get to hear my interviews, together with my interpretation of what has happened in the past to lead up to the creation of the operating system Tizen.

    Edgar Villchur

    \n

    \nFrom Wikipedia, the free encyclopedia (https://en.wikipedia.org/wiki/Edgar_Villchur)\n

    \n

    \nEdgar Marion Villchur (28 May 1917 - 17 October 2011) was an American inventor, educator, and writer widely known for his 1954 invention of the acoustic suspension loudspeaker which revolutionized the field of high-fidelity equipment. A speaker Villchur developed, the AR-3, is exhibited at the The Smithsonian Institutions Information Age Exhibit in Washington, DC.
    \nVillchur's speaker systems provided improved bass response while reducing the speaker's cabinet size. Acoustic Research, Inc. (AR), of which he was president from 1954 to 1967, manufactured high-fidelity loudspeakers, turntables, and other stereo components of his design, and demonstrated their quality through live vs. recorded concerts. The companys market share grew to 32 percent by 1966. After leaving AR, Villchur researched hearing aid technology, developing the multichannel compression hearing aid, which became the industry standard for hearing aids.\n

    Henry Kloss

    \n

    \nFrom Wikipedia, the free encyclopedia (https://en.wikipedia.org/wiki/Henry_Kloss)\n

    \n

    \nHenry Kloss (1929, Altoona, PA - January 31, 2002, Cambridge, MA) was a prominent American audio engineer and businessman who helped advance high fidelity loudspeaker and radio receiver technology beginning in the 1950s. Kloss (pronounced with a long o, like \"close\") was an undergraduate student in physics at Massachusetts Institute of Technology (class of 1953), but never received a degree. He was responsible for a number of innovations, including the acoustic suspension loudspeaker and the high fidelity cassette deck. In 2000, Kloss was one of the first inductees into the Consumer Electronics Association's Hall of Fame. He earned an Emmy Award for his development of a projection television system, the Advent Video Beam 1000.\n

    \n

    Acoustic Research

    \n

    \nFrom Wikipedia, the free encyclopedia (https://en.wikipedia.org/wiki/Acoustic_Research)\n

    \n

    \nAcoustic Research was a Cambridge, Massachusetts-based company that manufactured high-end audio equipment. The brand is now owned by Audiovox. Acoustic Research was well known for the AR-3 series of speaker systems, which used the 12-inch (305 mm) acoustic suspension woofer of the AR-1 with newly designed dome mid-range and high-frequency drivers, which were the first of their kind. AR's line of acoustic suspension speakers were extraordinary for their time, as they were the first loudspeakers with flat response, extended bass, wide dispersion, small size, and reasonable cost.\n

    Slackware

    \n

    From Wikipedia, the free encyclopedia

    \n

    \nSlackware is a free and open source Linux-based operating system. It was one of the earliest operating systems to be built on top of the Linux kernel and is the oldest currently being maintained. Slackware was created by Patrick Volkerding of Slackware Linux, Inc. in 1993. The current stable version is 13.37, released on April 27, 2011.
    \nSlackware aims for design stability and simplicity, and to be the most \"Unix-like\" Linux distribution, making as few modifications as possible to software packages from upstream and using plain text files and a small set of shell scripts for configuration and administration.\n

    The Golden Book of Chemistry Experiments

    \n

    \n\"a
    \nThe Golden Book of Chemistry Experiments was a children's chemistry book written in the 1960s by Robert Brent and illustrated by Harry Lazarus and published by Western Publishing in their Golden Books series. Many of the experiments contained in the book are now considered \"dangerous for unsupervised children\"[citation needed], and would not appear in a modern children's chemistry book[citation needed]. OCLC lists only 126 copies of this book in libraries worldwide.
    \nThe book was a source of inspiration to David Hahn, nicknamed \"the Radioactive Boy Scout\" by the media, who tried to collect a sample of every chemical element and also built a model nuclear reactor, which led to the involvement of the authorities.

    Interviews and a look at FSCONS 2011

    \n\n

    Today you will hear two interviews from FSCONS 2010. The audio is of \"conference quality\", that is, there are a lot of noice in the background. Not much to do about that, I am sorry. But it is two really great interviews, so well worth it!

    \n\n

    But as a start I have a look at what will take place during the coming FSCONS 2011, that will start 2011-11-11 and continue through the whole weekend. I read from the schedule, and mention some of the topics and presenters who will be there.

    Salve J. Nilsen - Kaizendo: Customizable schoolboks

    \n\n

    Imagine a schoolbook where the pupil and her teacher can choose the topic depth, clarity of text and homework difficulty as needed and necessary.

    \n\n

    Add alternatives for teachers (supporting different instructional methods, teaching styles), schools (variations in chapter content based on time constraints or policy) and parents (having a topic summary to read before helping with homework.) This is what we mean with customizable textbooks.

    \n\n\n\n\n

    Ole Tange - GNU Parallel

    \n\n

    GNU parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU parallel can then split the input and pipe it into commands in parallel.

    Trivial File Transfer Protocol

    \n

    From Wikipedia, the free encyclopedia

    \n

    https://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol

    \n\n

    \nTrivial File Transfer Protocol (TFTP) is a file transfer protocol known for its simplicity.[citation needed] It is generally used for automated transfer of configuration or boot files between machines in a local environment. Compared to FTP, TFTP is extremely limited, providing no authentication, and is rarely used interactively by a user.
    \n
    \nDue to its simple design, TFTP could be implemented using a very small amount of memory. It is therefore useful for booting computers such as routers which may not have any data storage devices. It is an element of the Preboot Execution Environment (PXE) network boot protocol, where it is implemented in the firmware BIOS of the host's network card.
    \n
    \nIt is also used to transfer small amounts of data between hosts on a network, such as IP phone firmware or operating system images when a remote X Window System terminal or any other thin client boots from a network host or server. The initial stages of some network based installation systems (such as Solaris Jumpstart, Red Hat Kickstart, Symantec Ghost and Windows NT's Remote Installation Services) use TFTP to load a basic kernel that performs the actual installation.
    \n
    \nTFTP was first defined in 1980 by IEN 133.[1] It is currently defined by RFC 1350. There have been some extensions to the TFTP protocol documented in later RFC's (see the section on Extensions, below). TFTP is based in part on the earlier protocol EFTP, which was part of the PUP protocol suite. TFTP support appeared first as part of 4.3 BSD.
    \n
    \nDue to the lack of security, it is dangerous to use it over the Internet. Thus, TFTP is generally only used on private, local networks.\n

    \n
    \nThe Freecycle Network (often abbreviated TFN or just known as Freecycle) is a non-profit organization registered in the state of Arizona, USA, and separately registered as a UK charity, that organizes a worldwide network of \"gifting\" groups, aiming to divert reusable goods from landfills. It provides a worldwide online registry, and coordinates the creation of local groups and forums for individuals and non-profits to offer and receive free items for reuse or recycling, promoting gift economics as a motivating cultural outlook. \"Changing the world one gift at a time\" is The Freecycle Network's official tagline.

    \nToday we're going back in time, to a classic audio drama performance by the Mercury Theater and was originally aired in Aug 29, 1938. It is an adaptation of the classic novel The Count of Monte Cristo, by Alexandre Dumas.

    \n

    \n

    Mercury Theatre

    \n

    \n\"Orson
    \nThe Mercury Theatre was a theatre company founded in New York City in 1937 by Orson Welles and John Houseman. After a string of live theatrical productions, in 1938 the Mercury Theatre progressed into their best-known period as The Mercury Theatre on the Air, a radio series that included one of the most notable and infamous radio broadcasts of all time, The War of the Worlds, broadcast on October 30, 1938. The Mercury Theatre on the Air produced live radio dramas in 1938-1940 and again briefly in 1946.\n

    \n

    The Count of Monte Cristo

    \n

    \nThe Count of Monte Cristo (French: Le Comte de Monte-Cristo) is an adventure novel by Alexandre Dumas. It is often considered to be, along with The Three Musketeers, Dumas's most popular work. He completed the work in 1844. Like many of his novels, it is expanded from the plot outlines suggested by his collaborating ghostwriter Auguste Maquet.

    \n

    \"photo

    \n

    \nThe story takes place in France, Italy, islands in the Mediterranean and the Levant during the historical events of 1815–1838 (from just before the Hundred Days through to the reign of Louis-Philippe of France). The historical setting is a fundamental element of the book. An adventure story primarily concerned with themes of hope, justice, vengeance, mercy and forgiveness, it tells of a man who is wrongfully imprisoned, escapes from jail, acquires a fortune and sets about getting revenge on the men who destroyed his life. However, his plans also have devastating consequences for the innocent as well as the guilty. The book is considered a literary classic today. According to Luc Sante, \"The Count of Monte Cristo has become a fixture of Western civilization's literature, as inescapable and immediately identifiable as Mickey Mouse, Noah's flood, and the story of Little Red Riding Hood.\"\n

    Apple Lisa

    \n

    \nFrom Wikipedia, the free encyclopedia
    \nhttps://en.wikipedia.org/wiki/Apple_Lisa
    \nThe Apple Lisa - also known as the Lisa - is a personal computer designed by Apple Computer, Inc. (now Apple, Inc.) during the early 1980s.
    \n\nDevelopment of the Lisa began in 1978 as a powerful personal computer with a graphical user interface (GUI) targeted toward business customers.
    \n\nIn 1982, Steve Jobs was forced out of the Lisa project, so he joined the Macintosh project instead. The Macintosh is not a direct descendant of Lisa, although there are obvious similarities between the systems and the final revision, the Lisa 2/10, was modified and sold as the Macintosh XL.
    \n\nThe Lisa was a more advanced system than the Macintosh of that time in many respects, such as its inclusion of protected memory, cooperative multitasking, a generally more sophisticated hard disk based operating system, a built-in screensaver, an advanced calculator with a paper tape and RPN, support for up to two megabytes (MB) of RAM, expansion slots, a numeric keypad, data corruption protection schemes such as block sparing, non-physical file names (with the ability to have multiple documents with the same name), and a larger higher-resolution display. It would be many years before many of those features were implemented on the Macintosh platform. Protected memory, for instance, did not arrive until the Mac OS X operating system was released in 2001. The Macintosh featured a faster 68000 processor (7.89 MHz) and sound. The complexity of the Lisa operating system and its programs taxed the 5 MHz Motorola 68000 microprocessor so that consumers said it felt sluggish, particularly when scrolling in documents.

    TRS-80

    \n

    \nFrom Wikipedia, the free encyclopedia\nhttps://en.wikipedia.org/wiki/TRS_80
    \nTRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December. The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation's leading position in what Byte Magazine called the \"1977 Trinity\" (Apple, Commodore and Tandy) had much to do with Tandy's retailing the computer through more than 3000 of its Radio Shack (Tandy in Europe) storefronts. Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its Floating Point BASIC programming language, an included monitor, and a starting price of $600. The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery. One major drawback of the original system was the massive RF interference it caused in surrounding electronics. This became a problem when it was determined to violate FCC regulations, leading to the Model I's phase out in favor of the new Model III.
    \nBy 1979, the TRS-80 had the largest available selection of software in the microcomputer market.
    \n....
    \nIn July 1980 Tandy released the Model III. The improvements of the Model III over the Model I included built-in lower case, a better keyboard, 1500-baud cassette interface, and a faster (2.03 MHz) Z-80 processor. With the introduction of the Model III, Model I production was discontinued as it did not comply with new FCC regulations as of 1 January 1981 regarding electromagnetic interference. The Model I radiated so much interference that while playing games an AM radio placed next to the computer could be used to provide sounds.
    \n\nThe Model III could run about 80% of Model I software, but used an incompatible disk format. Customers and developers complained of bugs in its BASIC and the TRSDOS operating system. The computer also came with the option of integrated disk drives. Since they took power from the same supply as the motherboard and screen, which was not upgraded for the disk drive models, it was common to see the screen image shrink noticeably during drive access.

    Commadore 128

    \n

    \nhttps://en.wikipedia.org/wiki/Commodore_128
    \nThe Commodore 128 (C128, CBM 128, C=128) home/personal computer was the last 8-bit machine commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling Commodore 64.\n
    \nThe C128 was a significantly expanded successor to the C64 and unlike the earlier Commodore Plus/4, nearly full compatibility with the C64 was retained, in both hardware and software. The new machine featured 128 KB of RAM, in two 64 KB banks and an 80-column RGBI video output (driven by the 8563 VDC chip with 16 KB dedicated video RAM), as well as a substantially redesigned case and keyboard. Also included was a Zilog Z80 CPU which allowed the C128 to run CP/M, as an alternate to the usual Commodore BASIC environment.\n
    \nThe primary hardware designer of the C128 was Bil Herd, who had worked on the Plus/4. Other hardware engineers were Dave Haynie and Frank Palaia, while the IC design work was done by Dave DiOrio. The main Commodore system software was developed by Fred Bowen and Terry Ryan, while the CP/M subsystem was developed by Von Ertwine\n

    Kernel News: Mat

    \n

    Time: 1:56
    Latest RC release is 3.2-rc5 released on Friday 12/9 at 6pm Eastern standard time.

    \n

    It has been slightly over a week since the last rc release. And rc5 is bigger in number of commits. Many of the commits are small, so it is possible that the *diff* will be smaller than both -rc2 and -rc4 were.

    \n

    A big part of this release is that Ingo is back, and had a backlog. That isn’t enough to explain it all. There were xfs and btrfs changes, along with network updates, and the usual 50% random driver updates.

    \n

    Greg KH announced the release of the 2.6.32.50, 3.0.13, and 3.1.5 stable kernels 12/9.

    \n

    The 2.6.32.50 kernel had 28 files changed, 164 insertions, and 54 deletions.
    The 3.0.13 kernel had 93 files changed, 659 insertions, and 201 deletions.
    The 3.1.5 kernel had 135 files changed, 1170 insertions, and 471 deletions.

    \n

    Kernel Quote of The Week:

    \n

    Hey Linus stop working on Subsurface, The Scuba Diving Log that doesn’t suck, during the week so you can get the latest RC out before 6pm eastern time so it is easier for me to do these updates. (insert appropriate smiley here)

    jQuery Tells The Real Story About Plugin Site, or Why You Should Have a Backup More Recent Than a Year Old

    \n

    The jQuery plugins site devolopers have finaly told the real story, in a blog posting. The plugins site went down about a week ago with just this message: “The plugins site is currently unavailable. We’ve been looking to provide a higher-quality, spam-free expierence at the plugins site for some time and we have decided to temporarily shutter the existing site. We will be providing more details on the new plugins site soon, so that plugin authors can hit the ground running with our new submission process.” What really happened was, in an attempt to clean up the spam using Drupal Views Bulk Operations, all of the plugins were deleted. And the only backup was a year old. The developers asked for forgiveness and some help in developing a completely new plugins site. The plugins site needed renovations for quite some time. Due to the spam issue and because of how plugins were manged through the CMS that was cluttered and awkward. They were planning on replacing the site when events caused an imdeiate need. When I say events I mean the accidental deletion and lack of backup was the impetus to move those plans into action. jQuery plugin developers should create a GitHub presence, even if they just mirror their existing source code management. The new site still being developed on github.com/jquery/plugins.jquery.com/ and there is currently no date for its launch.

    Download.com accused of wrapping nmap in a “trojan installer”

    \n

    Nmaps author says CBS Interactive and CNET’s Download.com are wrapping the open source application in a proprietary installer. In the past, they have never altered the application downloads they serve up, they have been changing that over the last six months. Gordon “Fyodor” Lyon, lays out his issues in a posting to the Nmap Hackers mailing list. He claims the installer does thing like install the ‘StartNow’ toolbar”, makes Bing the default search engine, and then sets the users home page to MSN. This is how a “trojan installer” functions. If the installer is seperated from the download and sent to VirusTotal it shows that ten of the 42 scanners, they run it against, identify it as a trojan or adware installer. Also the Nmap trademark is displayed next to offers to install software, as if the Nmap organization supports these products. As Nmap is not under the plain GPL but under an enhanced version that specifically prohibits aggregation into a proprietary executable installer.
    Download.com initially claimed its scheme is simple for developers to opt-out of. The opt out is not automatic though. Download.com says “all opt-out requests are carefully reviewed on a case by case basis.” Lyon is looking for a US copyright attorney and wants to get the word to the hundreds of users who use Download.com every week to download Nmap.
    CBS’s Download.com site has been called out for this type of behaviour before. In August, ExtremeTech claimed similar behaviour with the media player VLC. According to an FAQ from CBS this installer software was rolled out in July.
    After the fecal matter hit the fan on this Download.COM back pedaled in a big way. In a statement, Sean Murphy, the Vice President and General Manager of Download.com said, “The bundling of this software was a mistake on our part and we apologize to the user and developer communities for the unrest it caused.” Then adding that they had “reviewed all open source files in our catalog to ensure none are being bundled”.
    Lyon posted an update, stating that Microsoft had been in contact with him and claimed they “didn’t know they were sponsoring CNET to trojan open source software”. Microsoft also stated that they had stopped the practice, which seems odd since they said that they were unaware that it was happening. So now the Download.com installer changed to install the “Babylon toolbar” which did different search engine redirection. CNET then later removed that and is now installing its own “techtracker” tool for updating downloaded software. However they are also restoring the “Direct download link” which allows users to download files without having to download the “download manager”.
    Who knows if these changes will quell the controversey. The changes only affect open source software and the proprietary freeware and trial software on Download.com will still have the Download.com Installer packaging. A number of open source programs at Download.COM still had an installer wrapping them. There has been no general apology for bundling GPL software with closed source installers.

    Researchers at Google Have Proposed s Fix to The SSL Dilemma

    \n

    Google researchers Adam Langley and Ben Laurie have proposed a new method for ensuring the trustworthiness of the public key infrastructure (PKI) underpinning HTTPS. Thier idea is based on a public list of all certificates ever issued by certificate authorities. The two problems with how the current system works are. First, if an attacker can comprimise any of the more than 100 certificate authorities and aquire a certificate for a server such as amazon.com, end users would not be able to tell the fraudulant site from the real one. Second, the way the system currently works Amazon would not be able to detect the fraud either.
    Langley and Laurie believe that a public list would mitigate both problems. Whenever a website offered up a certificate, the browser would check the supplied certificate against one of these public lists. If the browser did not find the certificate on any of the lists, the site would be treated as untrusted. Companies would then be able to check these lists regularly, to locate any fraudulent certificates. Which means that even if a criminal was able to obtain a fake certificate, they could not use it efectively. Merkle signature trees would be used to maintain the integrity of the lists.
    The proposals might not be implemented and, if it is, noone knows over what sort of timescale. There are also other alternatives being proposed like Firefoxs’ extension Convergence being pursued by security expert Moxie Marlinspike.

    Android’s Revenge on Apple’s iPhone & iPad

    \n

    Could Apple be regretting its world-wide war on Android? A German court issued a preliminary injunction on Motorola’s behalf that prevents European sales of all Apple’s 3G-enabled devices. Android-power Motorola Mobility, soon to be a part of Google, used a patent to thwart the competition. Apple has been using design and software patents in order to attack Android world wide. So I don’t think this could have happened to a nicer company.

    \n

    Regretably the patent being used, Method for performing a countdown function during a mobile-originated transfer for a packet radio system, is an excellent example of brain dead software patents. Almost as bad as Apple trying to block anybody from creating a rectangular phone or tablet as it would infringe on thier “unique” design. Thing like this sadly are not unusual but equate to little more than Intelectual Property (IP) blackmail. Just check out U.S. Patent No. 6,359,898 and its European Union equivalent, EP1010336 (B1) ? 2003-03-19. They basicly describe performing a countdown over a 3G connection. You know lik, “Ten seconds to complete your download, three, two, one, download complete.” Oh, obviously an original idea indeed.

    \n

    So you say why is a countdown mechanism so essential that a court would rule that Apple would be in violation and unable to sell thier products in Europe. Well so does Apple which is why they have appealled using a Fair, Reasonable, and Non-Discriminatory (FRAND) defense. [Tony this is a link to a PDF that explains a frand defense please embed it https://www.ucl.ac.uk/laws/jevons/papers/colloquium_2007/jevons07_glader.pdf] This defenses core argument is that this feature is not an essential component to 3G mobile telephony. I and I also assume you all understand that, but the German court wasn’t going for it.

    \n

    So this will go on for a while in the court system with suit and counter suit. And in the end it will only delay the sale of Apple products in the EU. But another side effect is that no matter where you buy your smartphone it will cost you more because thes kinds of court battles do not come cheap. I have a suggestion to all of these patent mongers and trolls, knock it off and just compete in the market place instead of the court room.

    Get top-quality open source security tools in one distro

    \n

    If you could have just one toolkit for network security, which one would you choose? I mean the one toolkit that had all of the functionality you needed for securing, analyzing, monitoring, and validating your network. Would it be BackTrack, Deft, or Helix? Well I have used two of those and I have found a distro that I think kicks thier ass. After you have checked out Network Security Toolkit (NST), I believe that you will choose it also.

    \n

    This live DVD is based on Fedora. NST was designed to bring you easy access to the best Open Source Network Security Applications. It should run on most x86/x86_64 platforms. The intent of this distrobution is to provide network security administrators with a complete set of tools. Most of the tools in INSECURE.ORGs Top 100 Security Tools are in this kit. An advanced Web User Interface (WUI) is provided for system administration, navigation, automation, geolocation and configuration for many of the network and security applications in distribution.

    \n

    Here are some of the tools that come with NST:

    \n

    Aircrack NG: A wireless sniffer and WEP/WPA-PSK key cracker
    Airsnort: A wireless LAN (WLAN) tool that recovers encryption keys.

    \n

    Installing NST is as simple and easy as any other major Linux distribution out there today. After downloading the DVD image burn it out to disk, then pop it in and and boot up. You can choose to either boot into console or graphical mode, recommend the graphical mode even though it is GNOME 3. If your hardware will not support GNOME 3 you can opt to fall back on Classic GNOME. After bootup you will see the default live user enter the password nst2003 and let the desktop load. Once the desktop has fully loaded you can either take it for a test drive or jump right into the install. In order to install it you have to go to Applications > System Tools > Install NST To Hard Drive. If you have installed any Linux distribution before you will find no surprises here. When the installation is complete, or the live version is up and running, you can start experimenting with the tools. There are hundreds of available tools here to help you monitor, secure, analyze, and do practicly anything else on your network.

    Carrier IQ [...] has been hit with two class-action lawsuits from users worried about how the company’s software tracks their smartphone activity. Carrier IQ, of course, professes its innocence. But the company has also received some public support from security researchers who say Carrier IQ’s software is only tracking diagnostic information and likely is not violating user privacy.

    \n

    Dan Lynch

    \n

    \"MyHello and welcome, I'm Dan. A writer, musician, developer, broadcaster and hopeless geek from Liverpool in the UK. This site is the hub of everything I do online, or at least it's supposed to be but it still needs work. I'm committed to Free & Open Source Software and Creative Commons, I write and broadcast about both, mainly through the Linux Outlaws and Rathole Radio podcasts. You may also know me as a host of FLOSS Weekly on the TWIT Network.

    \n

    Rathole Radio is my music show where I play a wide selection of the best music on the net. I interview artists, tell silly stories, have live votes and even play songs myself. The music is very eclectic because I believe that all styles have good and bad within them. I want people to open their minds and not pigeon-hole everything. I only play one \"style\" of music, stuff I like.

    \n

    Linux Outlaws is a weekly show where I discuss the latest happenings in the Open Source technology world and with my German co-host and friend Fab. It's grown beyond anything we could have imagined. We get tens of thousands of downloads per show, it's taken me to different parts of the world and allowed me to meet and share time with many of my technology heroes. I'm very lucky. Below you will see the latest content from my blog and both these podcasts. You can also use the links on the menu to find more specialised information about my music and other things.

    \n

    I sing and play guitar in a band called 20lb Sounds. We recently launched our website with free music downloads and we hope to build up a community there. I'm calling it the 20lb Army, so sign up and join the fun :)

    \n

    \"\"I organised a large Free Software and Free Culture event in Liverpool called OggCamp10. Strange name I know but the site explains all that. It took place on 1st and 2nd of May 2010, we were joined by many great FOSS fans and developers from around the world. Not only that but on Friday April 30th 2010 I also ran a successful Rathole Radio gig with David Rovics and Attila The Stockbroker to kick the weekend off.

    \n

    I support the Open Rights Group and I'm very concerned about digital rights and political matters in the UK. I'm a proud member of both Liverpool LUG and Chester LUG and regularly attend meetings at both. Is this two timing or just a real commitment to FOSS? I'll let you decide ;)

    \n

    Thanks for visiting. Feel free to hang around a while and put your feet up.

    Easy Backup, Recovery & Bare Metal Restore

    \n

    \n\"How\n

    \n

    Redo Backup and Recovery is so simple that anyone can use it. It is the easiest, most complete disaster recovery solution available. It allows bare-metal restore. Bare metal restore means that even if your hard drive melts or gets completely erased by a virus, you can have a completely-functional system back up and running in as little as 10 minutes.

    \n\n

    All your documents and settings will be restored to the exact same state they were in when the last snapshot was taken. Redo Backup and Recovery is a live CD, so it does not matter if you use Windows or Linux. You can use the same tool to backup and restore every machine. And because it is open source released under the GPL, it is completely free for personal and commercial use.

    \n\n

    More Features, Less Complex

    \n

    Redo Backup has the most features coupled with the simplest, most user-friendly interface:

    \n
      \n
    • Easy graphical user interface boots from CD in less than a minute
      • \n
    • No installation needed; runs from a CD-ROM or a USB stick

    \nIn today's show Ken has a discussion with Alister Munroe about product lifecycle management at OggCamp 11

    \n\n

    Product lifecycle management

    \n

    From Wikipedia, the free encyclopedia

    \n

    A generic lifecycle of products

    \n

    \n\"PLM\"\nIn industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from its conception, through design and manufacture, to service and disposal. PLM integrates people, data, processes and business systems and provides a product information backbone for companies and their extended enterprise.\n

    \n

    \nProduct lifecycle management (PLM) should be distinguished from 'Product life cycle management (marketing)' (PLCM). PLM describes the engineering aspect of a product, from managing descriptions and properties of a product through its development and useful life; whereas, PLCM refers to the commercial management of life of a product in the business market with respect to costs and sales measures.\n

    \n

    \nProduct lifecycle management is one of the four cornerstones of a corporation's information technology structure. All companies need to manage communications and information with their customers (CRM-customer relationship management), their suppliers (SCM-supply chain management), their resources within the enterprise (ERP-enterprise resource planning) and their planning (SDLC-systems development life cycle). In addition, manufacturing engineering companies must also develop, describe, manage and communicate information about their products.\n

    \n

    \nOne form of PLM is called people-centric PLM. While traditional PLM tools have been deployed only on release or during the release phase, people-centric PLM targets the design phase.\nAs of 2009, ICT development (EU-funded PROMISE project 2004–2008) has allowed PLM to extend beyond traditional PLM and integrate sensor data and real time 'lifecycle event data' into PLM, as well as allowing this information to be made available to different players in the total lifecycle of an individual product (closing the information loop). This has resulted in the extension of PLM into closed-loop lifecycle management (CL2M).

    \n

    \nThis segment started with a discussion on accessibility. We are looking for a way to convert the audio to text so that deaf/hard of hearing people can enjoy our content. That lead to a discussion on Text to speech and that if you are uncomfortable or unable to record a show for HPR, then there are loads of people who will narrate a scrip for you.\n

    \n

    \nThe discussion turned to the question of how to pick topics for HPR and while the advice is to pick a topic that you're excited about you can always look at the Requested topics section of HPR at https://hackerpublicradio.org/contribute.php#requested_topics. If there is something that you would like to hear then mail the mailing list at hpr@hackerpublicradio.org (which you can join at https://hackerpublicradio.org/maillist ) or just email admin@hackerpublicradio.org and we'll add it to the Requested topic page.\n

    \n

    \nFor the record when we say topic we are not talking about the topic choclate bar.
    \nhttps://en.wikipedia.org/wiki/Topic_(chocolate_bar)\n

    \n

    \n\"Topic\n

    \n

    \nAfter discovering that HPR has a explicit tag in iTunes (https://www.apple.com/itunes/podcasts/specs.html#explicit) the conversation took a turn to how the topic of Adult content and that there are two sides to the story.
    \nhttps://hackerpublicradio.org/eps.php?id=0069 There's Pr0n on them there internets!
    \nhttps://hackerpublicradio.org/eps.php?id=0586 Miscellaneous Radio Theater 4096- The Internet is For Porn\n

    \n

    \nThis lead to the question of whither government censorship will force developments in how the Internet is used. This brought up mesh networks (we had a discussion in https://hackerpublicradio.org/eps.php?id=0069 with Juergen Schinker open wireless network) and how the Chaos Computer Club had a presentation on the Hackerspace Global Grid. From their FAQ \"We want to build a distributed network of ground stations to receive satellite communications. The first step is establishing a means of accurate synchronization for the distributed network. Next up are building various receiver modules (ADS-B, amateur satellites, etc) and data processing of received signals. A communication/control channel (read: sending data) is a future possibility but there are no fixed plans on how this could be implemented yet.\"\nhttps://shackspace.de/wiki/doku.php?id=project:hgg Hackerspace Global Grid. Sounds a bit like an open version of the Iridium satellite constellation\nhttps://en.wikipedia.org/wiki/Iridium_satellite_constellation Iridium satellite constellation
    \n

    \n

    \nAfter a discussion on Google+, the topic came on whither you needed to encode all 3 audio formats for HPR. The answer is no, not if you don't want to. If you do then you can download the script that Code Cruncher made from https://hackerpublicradio.org/incoming/processing/prep_audio.sh. That said it's enough to upload the show in almost any format and we'll convert it.\n

    \n

    \nTo round off the segment was a discussion of the https://theflatearthsociety.org/ who argue that \"The Flat Earth model is a belief that the Earth's shape is a plane or disk.\" (source wikipedia https://en.wikipedia.org/wiki/Flat_Earth_Theory.
    \n.... Which inevitably lead to the https://en.wikipedia.org/wiki/Turtles_all_the_way_down and of course that had to lead to https://www.terrypratchett.co.uk/ Terry Pratchett. At that point the Mumble server gave up and decided to go cry in a corner.\n

    \n

    \nThe discussion focused on how you can support free software and free culture with many paying more for \"Free\" software than they ever had for proprietary software. Many feel they pay what the can when they can.\n

    \n

    \nThe discussion move on to how artists can make a living.
    \nShould we draw the line between digital replication and physical replication as copyright infringement, although illegal, is not stealing. Not every download is a lost sale and the argument was made that in some cases \"piracy\" promotes the use of the software. There was much talk of the continual increase of the copyright terms.\n

    \n

    \nTime was then devoted to how artists could be compensated for their art and several examples were brought up of alternative means of generating revenue by cutting out the record labels and other middle men. \n

    \nHowdy folks, this is FiftyOneFifty.
    \nWhat you are about to hear is the result of me starting a mixdown recording in Mumble when Pokey said he was about ready to stop recording and go to bed. While it's all pretty tame, it's not entirely safe for work. I started recording sometime after midnight Central Time and the original file shows we talked for another two hours and fifteen minutes (deleting the pauses brings it down to about an hour and a half). At the end it's just me and Cobra2, proving that as in real life, I never know when it's time to gracefully leave a party :)
    \nAmong the other voices you will hear are Pokey, Delwin, JNeuster, Deltaray, DoorToDoorGeek, and I thought it was especially cool when the world wrapped around and Ken Fallon came back in after having gone to bed the night before. I didn't have the forethought to make note of all the handles active in the room, and the festivities of the evening did not enhance my recall, so I apologize to those I have overlooked. With the help of the community, I hope to get you proberly credited in the show notes, even if it is after the fact. \n

    \n

    \nI regret I wasn't able to participate or listen too in the entire thirteen hour scheduled recording, since I am speaking to the future I am sure I will be enjoying those missed hours even as you hear this. I want to add my voice in gratitude and congratulations to those who organized and participated in making this event a success.\n

    \nVote On SOPA Delayed Until Mid January At The Earliest
    \n
    \nThe SOPA (Stop Online Piracy Act) vote scheduled for 12/21/11 was postponed until January. A committee spokesperson said that they will not set a new vote date until they return from break in January. This means that the earliest that a scheduled vote could take place would be mid January. This is the second postponement of the committee vote on SOPA, which requires ISPs, Search Engines, and other content providers to alter DNS records and search results. Resulting in the censorship of foreign websites supposedly \"dedicated\" to providing copyright infringing material. The committee has already had two marathon sessions that ended abruptly after opponents expressed staunch apposition.

    \nNow you know who to boycott, but you also have to let them know why you are boycotting them.
    \n
    \nSeveral grassroots organizations along with a few tech companies are putting forth a strong effort against this legislation. They have had some effect as arguably the most egregious section has under gone a quick rewrite by Rep. Lamar Smith, Judiciary Committee chair and sponsor of this bill. The changes revealed on Monday 12/12/2011, make the definition of \"rogue websites\" more narrow. It also clarifies that the take down provisions only apply to foreign websites. There were also several changes intended to alleviate concerns that this legislation would interfere with the architecture of the Internet. Because as it it stands this bill would force American companies to break dns.
    \n
    \nThe NetCoalition which counts AOL, eBay, Facebook, foursquare, Google, IAC, Linkedin, Mozilla, OpnDNS, PayPal, Twitter, Wikipedia, Yahoo!, and the Zynga Game Netwrk as members is proposing a blackout day where all of these websites would go down and just show an anti-SOPA message to visitors when they come to these sites, claims Markham Erickson, who heads the NetCoalition trade association. If all of these sites went dark at the same time it would bring national commerce to a screeching halt. This action would also totally disrupt the lives of the majority of Americans hopefully alerting them to this serious issue and causing them to act.
    \n
    \nThere is still time to try and defeat this horrendous legislation and the people at \"DAILY KOS\" have made it incredibly easy. If you click on this link it will take you directly to a page the have set up that will walk you through sending your representative an email telling them to vote no on this steaming pile of fecal matter.

    \nGoDaddy Rescinds SOPA Support After Huge Boycott Initiative
    \nFull disclosure, I have a domain registered with GoDaddy they are just the registrar not the host.
    \n
    \nOn 12/22/2011 the fact that GoDaddy was actively supporting SOPA (Stop Online Piracy Act). The really egregious part was that not only did GoDaddy support SOPA they actually took such an active roll as righting parts of it. So a boycott was started on reddit, which took off like wildfire across the internet. One day later they announced that they were withdrawing their support for SOPA. It is however to late for many high profile domains. Wikimedia Foundation’s Jimmy Wales announced on Twitter that all Wikimedia’s domains will be moved off of GoDaddy. Cheezburger’s Ben Huh also pledged to move his 1000+ domains off of GoDaddy. Hundreds maybe even thousands more people across the internet joined them in leaving GoDaddy. YCombinator founder, Paul Graham issued a ban on all employees of any company on the official list of SOPA supporters from attending YC Demo Day. Here is what he had to say about the ban:
    \n
    \n\"Several of those companies [on the list] send people to Demo Day, and when I saw the list I thought: we should stop inviting them. So yes, we’ll remove anyone from those companies from the Demo Day invite list,\" He then went on to say this: \"If these companies are so clueless about technology that they think SOPA is a good idea, how could they be good investors?\"
    \nWarren Adelman, Go Daddy’s CEO, had this to say about them rescinding their support for SOPA:
    \n
    \n\"Fighting online piracy is of the utmost importance, which is why Go Daddy has been working to help craft revisions to this legislation - but we can clearly do better,\" He then went on to say this also: \"It’s very important that all Internet stakeholders work together on this. Getting it right is worth the wait. Go Daddy will support it when and if the Internet community supports it.\"
    \nThis is a huge win for the free and open internet. It shows that when you can manage to hit a company where it counts, in the bottom line, you really can make them change their position. When you read GoDaddy’s statement the weasilyness jumps right out at you. Which leads me to believe that they are just trying to take the heat off right now and will jump at supporting the next minor revision of SOPA.

    \nI am going to try and synopsize the information for you, however if you go to https://debian-handbook.info/ you can read the whole story ab out the book. The book is currently published in French under the title Cahier de l’admin Debian. It is the work of two Debian developers Raphaël Hertzog who maintains dpkg along with several other packages and Roland Mas who maintains argyll and a few other packages. They attempted to have several editors take on the English translation but none where willing to take the risk. The two then decided to do the translation themselves, and then self publish the work. In order to facilitate the translation they did a crowdfunding campaign which raised almost 15,000 EUR. They expect the translation to be done around April 2012. They however wanted to take this further and release the book under an open source licenses acceptable to Debian so that the book can be included in Debian as an installable package. Making it a simple apt-get away for anyone running Debian. They have set this goal at 25,000 EUR, you can make a donation to the \"liberation fund\" here , If you donate 10 EUR or more you are guaranteed a copy when it is ready. If they meet their goal of 25,000 EUR then everyone will be able to get a free copy. I made my donation already if I remember correctly it was about 13.74 USD. So i will get my copy but if we can push this over it would be a great thing. The last time I checked they were at about 65% of their goal.
    \n
    \nAnd now a little about the book. This book requires no prior knowledge of Debian. It will cover all of the topics that anyone needs to become an effective Debian administrator. From installation and update to compiling your own kernel and creating Debian packages from sources. Along with backup, migration and advanced topics like SELinux, automated installations, and virtualization. The first half of the book is for anyone who wants to run Debian. It will teach the basics like installing Debian with the Debian installer, finding documentation, basic troubleshooting, and problem solving. Then the second half of the book is server administrators. It will discuss things like securing the server, automating installations, using virtualization, and setting up common services like Apache, Postfix, OpenLDAP, SAMBA, NFS and many more. You can check out the complete table of contacts here
    \n
    \nThere is also a free sample chapter available \"The APT Tools.\" If you would like to check this out to ensure that the book is up to the quality that you expect then you can click here for a PDF of this great chapter. It covers all of the APT tools like apt-get, aptitude, and other associated tools
    \n
    \nNow to answer some of the questions you may have about this book:
    \nQ) Who is this book for?
    \nA) Anyone who’s interested by Debian. From a regular user, to the administrator of a small network, or that of a large corporation.
    \n
    \nQ) How long is it?
    \nA) The French paperback was about 450 pages.
    \n
    \nQ) What version of Debian does it cover?
    \nA) the current stable version \"Squeeze\"
    \n
    \nSo come people lets get out there and get your copy today and move the project that much closer to their goal of Open Sourcing this book.

    \n2011 The Year Of The Tech Giant Passing
    \n2011 has been a year in which we lost more tech giants than ever before, a total of fourteen. Lets start with arguably the best known on this list and end with the one I believe had the biggest impact:
    \n
    \nSteven Paul Jobs
    \nFebuary 1955 - October 2011
    \n
    \nJobs experimented with different pursuits before starting Apple Computers with Stephen Wozniak in the Jobs’ family garage. Steve Jobs vision in the consumer electronic market is un paralleled. Hence Apple’s many revolutionary products, such as the iPod, iPhone and iPad. Which are now seen as dictating the evolution of modern technology.
    \n
    \nRobert Morris
    \nThe Unix Encryption Guy
    \nJuly 1932 - June 2011
    \n
    \nAmong the Bell Labs researchers who worked on Unix with Thompson and Ritchie was Bob Morris, who developed Unix’s password system, math library, text-processing applications and crypt function. In 1986 Morris left to join the NSA, where he led the agency’s National Computer Security Center until 1994.
    \n
    \nJohn McCarthy
    \nOriginator Of AI
    \nSeptember 1927 - October 2011
    \n
    \nThe creator of the Lisp programming language and the \"father of artificial intelligence\" (he coined the term in 1956). In 1957 McCarthy started the first work on time-sharing on a computer. That original project led to Multics, which then led to Unix. In the early 1970s he predicted online shopping. This prediction led researcher Whitfield Diffie to create public-key cryptography used in the authentication of e-commerce documents.
    \n
    \nKen Olsen
    \nThe Digital Man
    \nFebruary 1926 - February 2011
    \n
    \nWhen he worked at MIT’s Lincoln Laboratory in the 50s took note of students queuing up to use an older model computer, called TX-0, even when a more modern and much faster mainframe was available. The big diffrence and the reason that the students lined up for the TX-0 was that the mainframe ran batch jobs and the TX-0 allowed for online interactivity. So in 1957 he and a colleague, Harlan Anderson, ran with that information and $70,000 in start up capital to start DEC (Digital Equipment Corp.) DEC went on to create PDP series of computers of which Ritchie and Thompson created Unix on a PDP-7.
    \n
    \nPaul Baran
    \nThe Packet Man
    \nApril 1926 - March 2011
    \n
    \nBaran while working as a researcher for the Rand Corp. in 1961came up the idea that messages can be broken down into smaller pieces, then sent to a destination even via multiple routes if necessary and then put back together when they arrive to ensure delivery. Arpanet adopted Packet switching as its means of communication, Arpanet then grew into the Internet, and eventually for local-area networks in the form of Ethernet.
    \n
    \nJean Bartik
    \nLast of the First Programmers
    \nDecember 1924 - March 2011
    \n
    \nShe was the last surviving member of the original programming team for the ENIAC. But that understates her work, she was the only female math graduate in her 1945 college, and she served as a lead programmer on the ENIAC project. Bartik also developed circuit logic and did design work under the direction of ENIAC’s hardware developer, J. Presper Eckert.
    \n
    \nJack Keil Wolf
    \nDisk Drivin’ Man
    \nFebruary 1926 - February 2011
    \n
    \nWolf did more than almost anyone else to use math to cram more data into magnetic drives, flash memory and electronic communications channels. In 1984, he moved to the new Center for Magnetic Recording Research at the University of California, San Diego. It was a good choice. Wolf and his students, dubbed the \"Wolf pack,\" cross-pollinated magnetic drive design with information theory, applying compression in increasingly creative ways, and spread Wolf’s ideas throughout the industry.
    \n
    \nJulius Blank
    \nCreator Of The Silicon In Silicon Valley
    \nJune 1925 - September 2011
    \n
    \nJulius Blank one of the \"Traitorous Eight\" engineers who founded Fairchild Semiconductor in 1957. He and his seven colleagues had acquired that unsavory nickname when they left Nobel Prize-winning physicist William Shockley just a year after being recruited to create a new kind of transistor at Shockley Labs. Before going to college, he had been trained as a machinist. Along with eventual venture capitalist Gene Kleiner, Blank built Fairchild’s machine shop, and created the manufacturing machinery that would produce the first silicon based transistors.
    \n
    \nRobert Galvin
    \nBreaker Of The AT&T Mobile Monopoly
    \nOctober 1922 - October 2011
    \n
    \nGalvin broke AT&T’s monopoly on mobile-phone service in the U.S. when he demonstrated a Motorola phone for president Reagan at the White House in 1981. Ronald Reagan then pushed the FCC to approve Motorola’s proposal for a competing cellular network. By the time Galvin retired as Motorola’s chairman in 1990, the company dominated the cellphone hardware business.
    \n
    \nGerald A. Lawson
    \nCreator Of The Video Game Cartridge
    \nDecember 1940 - April 2011
    \n
    \nJerry Lawson a 6-foot-6, more than 250 lbs. African-American, which was even more of an IT industry rarity in the 1970s than today. Lawson’s creation, the Fairchild Channel F, arrived in 1976, a year before Atari’s first home game system, and sparked an industry of third-party video games. Lawson discovered that the biggest challenge with plug-in cartridges was satisfying the FCC’s radio-frequency interference requirements. In a 2006 interview he describes the process:
    \n
    \n\"We had to put the whole motherboard in aluminum. We had a metal chute that went over the cartridge adapter to keep radiation in. Each time we made a cartridge, the FCC wanted to see it, and it had to be tested.\"
    \nIts biggest impact was on Lawson’s friends at Atari, who rushed their own cartridge-based home system into production. The rise of the video game had begun.
    \n
    \nGeorge Devol
    \nThe Man With The Robot Arm
    \nFebruary 1912 - August 2011
    \n
    \nGeorge Devol developed the first digitally programmable robot arm. He also invented a system for recording sound for movies in the 1930s, then switched to systems that used photoelectric cells to open and close doors and sort bar-coded packages. Devol turned his inventiveness to factory automation in the 1950s. The large programmable \"Unimate\" arm he developed used magnetic drum memory and discrete solid-state control components. It made its factory debut in 1961 on a General Motors assembly line in New Jersey, stacking freshly die-cast (and very hot) metal parts. Within 20 years, Devol’s Unimation was the biggest robotic-arm company in the world.
    \n
    \nLee Davenport
    \nAnti-Aircraft Innovator
    \nDecember 1915 - September 2011
    \n
    \nLee Davenport didn’t invent battlefield radar. He developed an anti-aircraft gun that combined radar with a computer to control anti-aircraft guns. At the Battle of the Bulge, the radar system was also used to spot German ground vehicles in the snowy terrain. In addition, the SCR-584 was used in 1944 to defend London against German buzz bombs. The SCR-584 crews were very effective in shooting down the buzz bombs.
    \n
    \nWilson Greatbatch
    \nHeartbeat of the Century
    \nSeptember 1919 - September 2011
    \n
    \nIn 1956 Wilson Greatbatch, an electrical-engineering professor at the University of Buffalo, made an electronic mistake that led to the invention of the pacemaker. He was building a heart rhythm monitor for the school’s Chronic Disease Research Institute when he attached a wrong-size resistor to a circuit, causing it to produce intermittent electrical pulses. Greatbatch realized that this might be used to regulate a damaged heart. Two years later, doctors at the Veterans Administration hospital in Buffalo demonstrated that a 2-cubic-in. implantable device built by Greatbatch could regulate a dog’s heart. In 1960 in Buffalo, 10 patients (including two children) received Greatbatch’s device, and its battery lasted two years or more. In 1972, Greatbatch was able to re-engineer the device with a new battery that worked for more than a decade.
    \n
    \nDennis M. Ritchie
    \nAn Originator of Unix, Inventor of C
    \nSeptember 1941 - October 2011
    \n
    \nDennis Ritchie is one of the authors of the Unix operating system, and designed the C programming language. And he promoted both, starting in the 1970s. You may ask how influential all of that work was? Well just look at the number of closed source Unix clones we have today, not to mention their Open Source brethren the BSDs. Along with Linux a Unix work alike. Not to mention C, which eight of the top ten programming languages descend from.
    \n
    \nRaspberry Pi, a Tiny But Powerful $25 PC -
    \nThe final Raspberry Pi will come in two flavors: A $25 version with 128MB of RAM and no network connection and a $35 one with Ethernet. Both versions will have USB and HDMI ports as well as analog video and audio outputs. It’s driven by a The 1080p video magic is driven by a 700MHz ARM processor, and the whole thing is powered by a 5-volt power supply.
    \nThe Year in Review: Desktop Linux Developments in 2011
    \nThe \"year in review\" pieces that proliferate old and new media alike around this time of year get tedious pretty fast. But because I’ve yet to see a good compilation of the major developments — and there were plenty of them — that affected desktop Linux in 2011

    Hello everyone its riddlebox, sorry its been so long since I have done a podcast.

    \n

    Today I am going to tell you about my kinda sorta home dvr that I have at the moment.

    \n

    No, this isn't another show talking about mythtv....even though the mythtv project is a good one...

    \n

    Our myth box at home died a while back and we lost three tuner cards which I hadn't realized how expensive the setup was getting to be needing all of the tuner cards and a back end server that could handle everything.

    \n

    So I looked at a debian server I have been using as my zoneminder server which just records two cameras when there is motion.\nI found a Java app called TED - or torrent episode downloader from www.Ted.nu.\nAs the name states it uses torrents to download the shows. With this application which you download and launch from the jar file..\nI had to use a --no-tray switch to get it to run.

    \n

    Once you open the jar file you are greeted with the app and a list of the popular shows.\nYou can tell it to start torrenting those shows and you can tell Ted the frequency of how often to look for new shows.\nYou can even tell it to get past shows.

    \n

    So I got Ted all configured the way I wanted, then I setup a guest SAMBA share on my downloads folder so my blue ray player can see the share, and now I just go to my blue ray player and see what shows are available to watch.\nSome shows may show up a couple days after they air but overall it works great.

    \nKernel Quote
    \n

    \n

    \n\"Here’s the different active kernel versions that I am maintaining at the moment:
    \n3.2.y – this will be maintained until 3.3 comes out
    \n3.1.y – there will be only one, maybe two, more releases of this tree
    \n3.0.y – this is the new \"longterm\" kernel release, it will be
    \nmaintained for 2 years at the minimum by me.
    \n2.6.32.y – this is the previous \"longterm\" kernel release. It is
    \napproaching it’s end-of-life, and I think I only have
    \nanother month or so doing releases of this. After I am
    \nfinished with it, it might be picked up by someone else, but
    \nI’m not going to promise anything.
    \nAll other longterm kernels are being maintained in various forms
    \n(usually quite sporadically, if at all), by other people, and I can not
    \nspeak for their lifetime at all, that is up to those individuals.\"
    \n– Greg Kroah-Hartman
    \nThere was also a bit of a dust up between Tim Gardner of Canonical and Greg Kroah-Hartman over maintenance of the 2.6.32 kernel once greg gives it up. It appears to have been started by a misunderstanding and a conclusion jump by Tim.

    \nMicrosoft Now Collects Extortion On Approximatley 70% Of All US Sales Of Androids
    \n

    \n

    \nLG is the latest victim to pay Microsoft’s extortion demands. They are the eleventh victim in this extortion scheme. A list of the other victims includes Samsung, HTC, and Acer. This leaves Motorola Mobility as the only major manufacturer to not sign an extortion agreement with Microsoft. I would wager that Microsoft has not even approached Motorola as Google now owns Motorola and those pockets are deep enough to scare off the Microsoft patent trolls. Microsoft now claims that they are collecting \"royalties\" on over 70% of all Android smart phones sold in the US. The terms of this latest agreement are unknown as Microsoft makes part of the agreement that the parties can not make public the patents covered by Microsoft’s claims. In other words a typical extortion agreement.

    \nThe MPAA Instigates A Dustup with Ars Technica
    \nOn 1/10 the MPAA (Motion Picture Associtation of America) said on it’s blog, \"… Ars Technica, a tech blog with a long history of challenging efforts to curb content theft,\". This entire claim by the MPAA appears to be Ars Technica opposing things in the past like the broadcast flag which would have allowed remote control of peoples home entertainment recording devices, along with their stand against DRM that prevents owners from ripping legal backup copies of their DVDs. Ars also has publicly opposed the horrendous SOPA legislation currently in front of Congress. It is obvious that the MPAA’s position is the wacky correlation of fighting for consumers’ rights is the equivalent of having no enforcement at all.
    \n

    \n

    \nNot that any representative of the MPAA would ever engage in outlandish statements to further their cause. Like this quote from Jack Valenti when he appeared before congress in 1982, \"I say to you that the VCR is to the American film producer and the American public as the Boston strangler is to the woman home alone.\"

    \nUnited States Migrates Spy Drone Control Panels From Windows To Linux
    \nLast September the ground control systems for the Reaper drones, which reside at the Creech Air Force Base in Nevada, became infected with a virus. When it happed the Air Force dismissed this intrusion as a nuisance that posed no real threat, it was however taken very seriously.
    \n

    \n

    \nStill the discovery of this virus on the Air Force’s systems was a huge embarrassment. This is what they had to say at the time:
    \n

    \n

    \n\"The malware in question is a credential stealer, not a key logger, found routinely on computer networks and is considered more of a nuisance than an operational threat. It is not designed to transmit data or video, nor is it designed to corrupt data, files or programs on the infected computer. Our tools and processes detect this type of malware as soon as it appears on the system, preventing further reach.\", they also went on to say, \"The ground system is separate from the flight control system Air Force pilots use to fly the aircraft remotely; the ability of the pilots to safely fly these aircraft remained secure throughout the incident,\"
    \nScreen shots of drone control computers posted by security researcher Mikko Hypponen show that some of the systems have been migrated from Microsoft Windows to Linux. In a statement Mikko Hypponen said,
    \n

    \n

    \n\"If I would need to select between Windows XP and a Linux based system while building a military system, I wouldn’t doubt a second which one I would take.\"
    \nOpen Source Surgery, a Robot called Raven takes Flight
    \n

    \n

    \nThe Raven 2 is a surgical robot with 7 degrees of freedom, compact electronics and two wing-like arms which end in tiny gripper claws designed to perform surgery on simulated patients. The robot’s software is compatible with Robot Operating System, an open source robotics coding platform.

    concr

    \n

    \nconcr is an encryption framework for use to partially encrypt configuration files, or any file for that matter. concr is for use in UNIX systems and consist of two parts, libconcr and confcrypt. libconcr is an API for reading partially encrypted files and generating keys. confcrypt is a user-application for encrypting files using keyfile database or manually specified keys.\n

    \n

    \nconcr leverages the own-by-root aspect of programs in UNIX systems and stores its decryption key inside of the application. Applications that use libconcr must be installed with execute-only permissions.\n

    \n

    \n\nWhen an application is linked with and makes use of concr it, when run for the first time, will generate a copy of itself containing a private rsa-key and output a public rsa-key. confcrypt is a user program that encrypts messages to be decrypted by second runs of the application. concr provides an api similar to that of libc for reading in files thus making it transparent to the application developer what is and is not encrypted in those files.\n

    Elfstedentocht

    \n

    \nFrom Wikipedia, the free encyclopedia\n

    \n

    \nThe Elfstedentocht (or, in West Frisian, Alvestêdetocht, sometimes in English : Eleven Cities Tour), at almost 200 km, is the world's largest speed skating competition and leisure skating tour, and is held in the province of Friesland, Netherlands only when the ice along the entire course is 15 cm thick.\n

    \n

    \nThe tour, almost 200 km in length, is conducted on frozen canals, rivers and lakes between the eleven historic Frisian cities: Leeuwarden, Sneek, IJlst, Sloten, Stavoren, Hindeloopen, Workum, Bolsward, Harlingen, Franeker, Dokkum then returning to Leeuwarden. The tour is not held every year, mostly because not every Dutch winter permits skating on natural ice. The last editions were in 1985, 1986 and 1997. Adding to that, the tour currently features about 15,000 amateur skaters taking part, putting high requirements on the quality of the ice. There is a stated regulatory requirement for the race to take place that the ice must be (and remain at) a minimum thickness of 15 centimetres along the entirety of the course. All skaters must be a member of the Association of the Eleven Frisian Cities. A starting permit is required. Further more, in each city the skater must collect a stamp, as well as a stamp from the three secret check points. The skater must finish before midnight.\n

    TGTM Newscast for 2012/02/08 DeepGeek

    \n

    We have had alot happen in the world since the last newscast, so\nlet's jump right in! We're also rich in audio interludes, so I will be\ninserting them almost between the non-tech news stories.\n

    \n

    Here is a news review:

    \n
      \n
    • Calls for Julian Assange to be tried as terrorist under NDAA-like law in 2010
      • \n
    • This story is important because there was a movement to have multiple political parties in Cuba. Cuba Keeps One Party, Sets Term Limits
      • \n
    • \n

      Let's start a segment of three stories regarding United States of America politics. First, a story about the struggle against the \"Electoral College\" system of voting, which is a key method this country uses to suppress anything besides to two dominant fascist (in the technical sense of being a marriage between corporations and government) parties. We will see how the state of Washington is fighting that system. After this, a story about the fight for decent medical care for the country within the state of California. Lastly, an editorial written by one of the co-chairs of the Socialist Party USA about Ron Paul.\n

      \n

      It should be noted that I am not yet \"endorsing\" the Socialist Party USA, merely covering their point of view which the corporate media ignores in order to keep them out of the minds of the people of the USA. That's the point of TGTM news, to report the stories they suppress. The Green Party USA is very interesting also.

      \n

      Jill Stein is fighting for candidacy for President with them, and she recently issued her own \"Peoples State of the Union (which I will link to in the \"other headlines\" section)\" right after Obama's State of the Union. While Obama's State Of The Union was very Ronald Regan, you know, with it's tough-guy statements about forcing other countries to respect us via Military Force and it's \"trickle down economics\" statements about boosting the economy by giving even more handouts to mega-corporations; Jill Stein's message was about \"the Green New Deal,\" about stimulating the economy with direct-to-locality stimulus. As matter of fact, she held a video chat direct to the people who got to ask her questions via chat room. Remembering that a union I regularly cover, the IWW, encourages it's members to work via worker co-operatives, I asked if co-ops would be locked out of the \"Green New Deal.\" Ms. Stein answered my question by stating that co-operatives were valid recipients of contracts, and that the point was that, historically, big corporations pocket too much for their owners, so she only wanted to lock out the Interstate and large corporations to aid small business units.

    Mr Gadgets calls in Apocalyptic year 2012 where he discusses Assembler, COBOL and Grace Hopper

    \n

    From: https://en.wikipedia.org/wiki/Grace_Hopper

    \n

    Rear Admiral Grace Murray Hopper (December 9, 1906 – January 1, 1992) was an American computer scientist and United States Navy officer. A pioneer in the field, she was one of the first programmers of the Harvard Mark I computer, and developed the first compiler for a computer programming language. She conceptualized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. She is credited with popularizing the term \"debugging\" for fixing computer glitches (motivated by an actual moth removed from the computer). Because of the breadth of her accomplishments and her naval rank, she is sometimes referred to as \"Amazing Grace.\" The U.S. Navy destroyer USS Hopper (DDG-70) was named for her, as was the Cray XE6 \"Hopper\" supercomputer at NERSC.

    \nFrom Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/Richard_Stallman\n

    \n

    \n\"Richard\nRichard Stallman, Free Software foundation\n\n

    \n

    \nRichard Matthew Stallman (born March 16, 1953), often shortened to rms, is an American software freedom activist and computer programmer. In September 1983, he launched the GNU Project to create a free Unix-like operating system, and he has been the project's lead architect and organizer. With the launch of the GNU Project, he initiated the free software movement; in October 1985 he founded the Free Software Foundation.
    \nStallman pioneered the concept of copyleft, and he is the main author of several copyleft licenses including the GNU General Public License, the most widely used free software license. Since the mid-1990s, Stallman has spent most of his time advocating for free software, as well as campaigning against software patents, digital rights management, and what he sees as excessive extension of copyright laws. Stallman has also developed a number of pieces of widely used software, including the original Emacs, the GNU Compiler Collection, the GNU Debugger, and various tools in the GNU coreutils. He co-founded the League for Programming Freedom in 1989.\n

    \n

    The Free Software Definition

    \n

    \nhttps://www.gnu.org/philosophy/free-sw.html
    \n
    \nA program is free software if the program's users have the four essential freedoms:\n

    \n
      \n
    • The freedom to run the program, for any purpose (freedom 0).
      • \n
    • The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
      • \n
    • The freedom to redistribute copies so you can help your neighbor (freedom 2).
      • \n
    • The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

    Free Software Foundation

    \n

    \nFrom Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/Free_Software_Foundation\n

    \n

    \n\"FSF\n

    \n

    \nThe Free Software Foundation (FSF) is a non-profit corporation founded by Richard Stallman on 4 October 1985 to support the free software movement, a copyleft-based movement which aims to promote the universal freedom to create, distribute and modify computer software. The FSF is incorporated in Massachusetts, USA.
    \nFrom its founding until the mid-1990s, FSF's funds were mostly used to employ software developers to write free software for the GNU Project. Since the mid-1990s, the FSF's employees and volunteers have mostly worked on legal and structural issues for the free software movement and the free software community.\nConsistent with its goals, only free software is used on FSF's computers.\n

    The other day I was copying a customer's files and settings from a old laptop to a new one. Much of this tedious task was handled automatically by Fab's Autobackup (https://fpnet.fr/, and 25% until Valentines Day BTW), but I was disappointed that his dozen WiFi access point profiles and passwords were not one among the settings that Fab's copied for me. For a family laptop, you usually just have to re-enter the password for just the home router, and maybe once again for your work wireless. If your are a tech for an enterprise, and the new mobile workstation needs to connect to multiple access points, you always wind up walking around the business or campus, connecting to each in SSID in turn and entering a different key. This time, the laptop would be used in multiple remote offices. The user would have been able to re-create those connections as he traveled to each office, but he asked me if it wouldn't be possible instead to transfer the profiles with the rest of his data.

    \n

    I had no doubt that I would be able to find a free tool to backup and restore wireless connections, but I have become wary of Windows utilities that can be found at the end of a Google search but have not been recommended by other techs or a trusted website. I was surprised to find my answer in some functions added to the DOS netsh, (or \"net shell\") command, starting with Windows Vista.

    \n

    Open a Windows command prompt on the laptop that already has the WiFi keys set up, ergo the old one, and type:

    \n
    netsh wlan show profiles
    \n

    then press return. This will give you a list of your existing wireless connection profiles by name (i.e. by SSID). Now you can pick a WiFi profile name and enter on the command line:

    \n
    netsh wlan export profile name=\"SSID_above_in_quotes\" folder=\"C:\\destination\"
    \n

    Quotes are required for the WiFi profile name, but not for the destination folder unless you use spaces in your Windows directory names. If you want to create export files for all your wireless connections, you may omit the \"name=\" part.

    \n
    netsh wlan export profile folder=<destination_path>
    \n

    Omitting \"file=\" of course creates export files in the current directory.

    \n

    The netsh wlan export profile command generates a .XML export file for each selected profile. Each export file contains an SSID, channel, encryption type and a hash of the encryption key to be transferred to the new laptop, except that it doesn't work, at least not for me and several others who posted articles to the web. On my first try, I was able to import everything but the encryption key, all the access points showed up in \"Manage Wireless Networks\", but I was prompted for a key when I tried to connect. I thought maybe this was Microsoft's attempt at security, but I could see a field for the hash in the .XML and when I went back to the article on netsh and it was clear I was supposed to get the keys too. A little more googlsearch revealed a second article on netsh that gave me an argument the first one omitted, adding key=clear at the very end of the netsh command causes the keys to be exported in clear text! Our command now looks like:

    \n
    netsh wlan export profile folder=<destination_path> key=clear
    \n

    Copy your .XML profile files to the new laptop (I am assuming via USB key). The filenames will be in the format:

    \n

    Wireless Network connection-<profile-name-same-as-SSID>.xml

    \n

    You understood me correctly, this DOS command generates file names with spaces in them. Copy the .XML files to the new system and import the profiles with:

    \n
    netsh add profile filename=\"<file name in quotes to account for spaces>.xml\"
    \n

    \nIt's not quite as odious as it looks because DOS now supports TAB completion, so you just have to type:

    \n

    netsh add profile filename=\"Wi and press <TAB>

    \n

    \nThe rest of the name of the first profile will be filled in, complete with the terminating quote. Press <ENTER> and you should get a message that wireless profile has been imported. To import the remaining profiles, just use <F3> or the up arrow and edit the last command. Since it was set to auto-connect, the laptop I was working on made a connection to the local access point the instant the corresponding profile was imported.

    \n

    Learning these new netsh functions may make configuring WiFi more convenient (I can maintain a library of wireless profiles for the organizations I service, or I could implement an encryption key update via a batch file). I can also see ominous security implications for networks where users aren't supposed to be privy to the connection keys and have access to pre-configured laptops, such as schools. One could whitelist the MAC addresses of only the organization's equipment, but there is always that visiting dignitary to whom you are expected to provide unfettered network access. Besides, anyone with access to the command line can use ipconfig to display the laptop's trusted MAC address, which can be cloned for access from the parking lot or from across the street. The only way I see to secure the connection from someone with physical access to a connected laptop is to install kiosk software that disables the command line.

    Installing Skype on 64-bit Fedora

    \n

    Last week I decided to install Skype as an alternative way to contact people with land lines. I haven't played with Skype since I had it on my Windows workstation, so I downloaded and installed the .rpm for Fedora 13+. All Skype has is a 32-bit package for Fedora, and sure enough, when I tried to launch Skype, the icon bounced around Compiz fashion, then the application item on the taskbar closed without doing anything. I looked for information in troubleshooting Skype from the logs, and an Arch wiki article told me I might have to create ~/.Skype/Logs, which I did. The application continued to crash without generating a log. I heard someone mention once in a call-in podcast that they'd had to perform additional steps to make 32-bit Skype work in 64 bit Fedora 15, and a Google search took me to the khAttAm blog (link below). I experienced some trepidation because the steps involve installing additional 32 bit libraries (if you heard me on the Hacker Public Radio New Years Eve shows, you might have heard me say I've experienced a bit of dependency hell over conflicts between 32 and 64 bit libraries) but the instructions in the article went flawlessly (I don't know if khattam.info represents one person or more than one, but you rock!).\nhttps://www.khattam.info/howto-install-skype-in-fedora-15-64-bit-2011-06-01.html

    \n

    First, as root run yum update

    \n

    Next, add the following line to /etc/rpm/macros (create it if it doesn't exist):

    \n
    %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}
    \n

    Finally, install these 32-bit libraries:

    \n
    \nyum install qt.i686 qt-x11.i686 libXv.i686 libXScrnSaver.i686\n
    \n

    After that, I was able to launch the application and log into my Skype account.

    \nHere's a flavour:
    \n\nThe tr, or translate (aka: transliterate) command, substitutes one more characters for another set of characters or it will delete a specified set of characters. The tr command takes input from standard in and writes to standard out. This simple example of the tr command translates some numbers into a word:

    \nI recently bought a roku XD box and I want to do a little review for you guys. First I would like to say that we have basic cable, and werent really looking to become \"cord cutters\". You can check out the roku site at www.roku.com.

    \n

    \n\"Roku\n

    \n

    \nFirst I bought it from Best buy for 79.99 I think it was 84 dollars with tax. First I cant believe how tiny this thing is! When you open the box, you have the device, a remote and some RCA AV Cables. The XD also only works with wireless internet. The one I bought does have a HDMI port on it. It works great and does Netflix and other services like Amazon and Hulu Plus. \n

    \n

    \nYou sign up for a roku account on the website and associate the roku box to that account. Which is close to what you do with most media type boxes nowadays like blueray players and stuff. The only difference is those devices only give you content from a couple places. The roku actually has channels, that you can add to your roku box. I have added many channels on it and I am watching lots of content from the web. With services like Popcorn flix, which shows you movies and during those movies there are some commercials. They arent really that bad its like 1 commercial when they show it. It is always the same commercial though. Which kinda gets annoying. \n

    \n

    \nI use Netflix, and Crackle on it was well. There are lots of news channels like NBC also I know that MLB and I think NHL have channels too. I was amazed at the selection of channels on the device. It would be nice if the roku site had a listing of all private channels. As it is hard to search the internet to find a list, then add the code on the roku site only to find out that the channel code doesn't work anymore. There really are so many channels that you can add it is hard to explain them all. \n

    \n

    \nMy wife and I both have android phones and we installed the roku remote control app which works great! As long as you are on the same wifi network as the roku you can control it. My wife is using the roku box for netflix and other services more than our blueray players because she likes the interface to netflix better. She says that just getting around the netflix channel is just so much easier! I even found a mythtv channel. All in all I am real happy with the Roku box and would recomend it to anyone to supplement their basic cable package. I think it really goes hand in hand with a basic cable or HD Antenna where you can get your network channels, but still get a lot of the extra content for free or a reasonable price.

    \n

    \nI will say that I would like to try Hulu Plus and see if I can slowly wean myself from Cable or HD Antenna. I really doubt it because of the way the cable companies are in the US. Right now since I get my internet from the cable company (Charter) if I get basic Digital television with it then I actually get the two of them for a cheaper price than if I just got the cable internet from them. I would like to end by saying that I know I have only mentioned a few of the channels that roku offers but there really are so many of them and they are scattered in many places that it is tough to know about them all. So if you want you can email me james.middendorff@gmail.com I am on google+ as well.

If a file is not specified or \"-\" is used, the cut command takes input from standard in. The cut command can be used to extract sections from a file or stream based upon a specific criteria. An example of this would be cutting specific fields from a csv (comma separated values) file. For instance, cut can be used to extract the name and email address from a csv file with the following content:\n\n

    Kernel Quote:
    \nThis was posted by Linus in response to Greg Kroah-Hartman publicly making fun of a kernel contributor for doing something massively stupid.

    \n

    “Publicly making fun of people is half the fun of open source programming.

    \n

    In fact, the real reason to eschew programming in closed environments is that you can’t embarrass people in public”

    \nUdev Source To Be Merged Into Systemd tree

    \n

    \tKay Sievers, lead developer for udev, announced on the Linux hotplug mailing list plans to merge the source code for udev into the systemd tree. When this happens systemd will continue forward using the udev version number, so it will jump from 45 to 184.

    \n

    \tAfter the merge it will still be possible to build it for non-systemd systems. He went on to say that builds of this nature will be supported for a long time to come. This is necessary so as not to break systems with initrds that lack systemd. Distributions that do not want to adopt systemd can build as they always have except they will need to use the systemd tar ball.

    \n

    \tThe decision to merge the two projects was based on the fact that init needs to be completely hotplug capable. Making udev’s device management and knowledge of device life cycles integral to systemd. This makes this merge a change in build scheme not a change in direction or interface. This leaves the libudev API untouched.

    \n

    \tSo what all of this boils down to after the brouhaha settles down is that in essence nothing really has changed.

    Google Glass, Jetpacks Must Be Just Around The Corner

    \n

    \tI have been a fan of science fiction since I could read. Well everyday reality seems to be catching up with the science fiction of my childhood. If you have not seen the video yet head on over to YouTube and check it out:
    \n
    \n These are the kinds of things we geeks have been saying are coming since we were children. They are so futuristic that I am still having a hard time believing that they are actually in testing.

    \n

    \tThe Internet rumor mill has been swirling around this for awhile now. Google calls it Project Glass and it is being developed at Google[X], Googles R&D laboratory. The announcement on Wednesday, 4/4 about field testing for Google Glass was released in a post on Google+ (https://plus.google.com/111626127367496192147/posts). It is however for Google employees only. The designs shown on Wednesday are just a selection they have more including one that can be incorporated into your existing eyewear.

    \n

    \tThe biggest questions raised by this announcement have already been answered. Those questions being, won’t these get in the way of reality, and, won’t these just separate us more from from real life, well according someone who has used these, in an interview with the NY Times, the answer is no:

    \n

    “They let technology get out of your way. If I want to take a picture I don’t have to reach into my pocket and take out my phone; I just press a button at the top of the glasses and that’s it.”

    \n

    \tThe glasses do have a unique look about them, and people will know you are wearing them right away. They will hopefully get smaller and be able to be integrated into a regular looking pair of glasses.

    \n

    \tI don’t care if these are impractical or don’t work I want a pair of these right now. This is the science fiction stuff I used to dream about when I was a kid. How far away are the personal jetpacks.

    ICANN Writes A How To For Governments To Seize Domains

    \n

    \tComing to you directly from the “Not Cool” department. It was pointed out to ICANN that it was providing a disservice by not speaking out against governments seizing domains. So what does ICANN do? They publish a white paper that is basicly a how to for governments to seize domains. They have also made public statements that they will work closer with governments to help them seize and censor domains. This unfortunate turn of events just further illustrates the uselessness of ICANN to protect the Internet. It instead shows how they are actively undermining the very principals of the Internet.

    IBM And Red Hat May Join OpenStack

    \n

    \tFrom the I made this up to sound important bag. GigaOm reports that IBM and Red Hat are joining OpenStack. Neither company nor OpenStack has confirmed this report. OpenStack was started about two years ago as joint effort between NASA and Rackspace. Since its inception it has grown immensely with over 150 companies and 2,000 developers. I do not know how much cache these two will bring to the party however as the list of companies already includes the likes of HP, Dell, Intel, AMD, and Cisco.

    \n

    \tOpenStack released the fifth version of its software this week code named Essex. They are having a Design Summit April 16-18 in San Francisco. This could be where new partners will be announced.

    KDE Tooltips— when is too much, too much? Well for me when it’s associated with KDE tool-tips
    \nDespite the fact that I am a big fan of KDE, there is one thing that annoys me every time I install a KDE-based distro—the numerous tool-tips and pop-ups that appear in an attempt to be helpful.

    \n

    Recently while searching for some KDE information, I found that someone else also had expressed similar sentiments and went on to list all of the tool-tips that he had disabled. His version of KDE was 4.5—but it had not changed too much for 4.8.1. Here are the various tooltips that I have deactivated.

    \n

    System Settings tool-tips: Are you bothered by KDE displaying the list of items for each configuration category within the System Setting area: Disable it thusly:.
    \n1. Open System Settings
    \n2. Select the Configure button
    \n3. Uncheck the “Show detailed tool-tips”
    \nIcon-only Task bar tool-tips: If you’re using the icon-only task bar, you will appreciate this information instructing how to suppress task bar pop-ups.
    \n1. Right-click on the task bar.
    \n2. Select Icon-only Task Manager Settings
    \n3. In the Appearance section, Select “Do Not Show” in the tool-tips drop-down and save.
    \nPanel balloon pop-ups: Do these balloons make you want to blow up? Selecting this option will suppress the pop-ups that appear when you hover over shortcuts and icons on the desktop.
    \n1. Open System Settings
    \n2. Select Workspace Appearance and Behavior
    \n3. Select Workspace Behavior
    \n4. Select Workspace
    \n5. In the Informational Tips widget, select the “Do not show” option.
    \n.
    \nTitle bar buttons (Maximize, Minimize, Close):
    \nOpen System Settings
    \nSelect Workspace Appearance
    \nSelect Window Decorations
    \nSelect the Configure Buttons button
    \nUncheck the “Show window button tool-tips” check box
    \nThis feature appears to be broken on my desktop—no tool-tips either way, plus my extra buttons with spacing are not appearing on the title bar. Perhaps my just downloaded and installed upgrade to 4.8.2 will fix this problem. ;)
    \nDolphin: Stopping the mother of all pop-up tooltips…This action prevents Dolphin from taking the content of the information panel (which can be set to appear on the right side) and repackaging it as a tool-tip..a very large tool-tip This may come in handy for some people, but for me it was over the top.
    \n1. Select the Settings menu
    \n2. Select the Configure Dolphin… option
    \n3. Select the General tab
    \n4. Uncheck the “Show tool-tips” check box.

    \n

    LibreOffice: The tool-tips that appear when you hover over the tool-bar will disappear.
    \n1. Select Tools, Options.
    \n2. Under General, uncheck the Tips box.

    \n\"Raspberry
    In today's show Klaas-Jan walks Ken throught the possibilities of the Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming. All for under $35.

    \n

    Connectors

    \n

    \n\"RCA
    \nComposite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. In contrast to component video (YPbPr) it contains all required video information, including colors in a single line-level signal. Like component video, composite-video cables do not carry audio and are often paired with audio cables (see RCA connector).\n

    \n

    \n\"A
    \nHDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting encrypted uncompressed digital data. HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio, auxiliary data, and implementations of the VESA EDID. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, high definition and 3D video signals; up to 8 channels of compressed or uncompressed digital audio; a Consumer Electronics Control (CEC) connection; and an Ethernet data connection.\n

    \n

    \nGeneral Purpose Input/Output (a.k.a. GPIO) is a generic pin on a chip whose behavior (including whether it is an input or output pin) can be controlled (programmed) through software.
    \nGPIO pins have no special purpose defined, and go unused by default. The idea is that sometimes the system integrator building a full system that uses the chip might find useful to have a handful of additional digital control lines, and having these available from the chip can save the hassle of having to arrange additional circuitry to provide them. For example, the Realtek ALC260 chips (audio codec) have 4 GPIO pins, which go unused by default. Some system integrators (Acer laptops) employing the ALC260 use the first GPIO (GPIO0) to turn on the amplifier used for the laptop's internal speakers and external headphone jack.\n

    \n

    \nA Universal Asynchronous Receiver/Transmitter, abbreviated UART is a type of \"asynchronous receiver/transmitter\", a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in conjunction with communication standards such as EIA, RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable and that the actual electric signaling levels and methods (such as differential signaling etc.) typically are handled by a special driver circuit external to the UART.
    \nA UART is usually an individual (or part of an) integrated circuit used for serial communications over a computer or peripheral device serial port. UARTs are now commonly included in microcontrollers. A dual UART, or DUART, combines two UARTs into a single chip. Many modern ICs now come with a UART that can also communicate synchronously; these devices are called USARTs (universal synchronous/asynchronous receiver/transmitter).\n

    \n

    \nI²C (\"i-squared cee\"; Inter-Integrated Circuit; generically referred to as \"two-wire interface\") is a multi-master serial single-ended computer bus invented by Philips that is used to attach low-speed peripherals to a motherboard, embedded system, cellphone, or other electronic device. Since the mid 1990s, several competitors (e.g., Siemens AG (later Infineon Technologies AG), NEC, Texas Instruments, STMicroelectronics (formerly SGS-Thomson), Motorola (later Freescale), Intersil, etc.) brought I²C products on the market, which are fully compatible with the NXP (formerly Philips's semiconductor division) I²C-system. As of October 10, 2006, no licensing fees are required to implement the I²C protocol. However, fees are still required to obtain I²C slave addresses allocated by NXP.
    \nSMBus, defined by Intel in 1995, is a subset of I²C that defines the protocols more strictly. One purpose of SMBus is to promote robustness and interoperability. Accordingly, modern I²C systems incorporate policies and rules from SMBus, sometimes supporting both I²C and SMBus with minimal re-configuration required.\n

    \n

    \n\"Serial
    The Serial Peripheral Interface Bus     or SPI (pronounced like \"S.P.I.\" or \"spy\") bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a \"four-wire\" serial bus, contrasting with three-, two-, and one-wire serial buses.\n

    You can't say we're not doing our public doody, we put the call out for the poor truck driver who lost his job due to them thieving bastards, the interwebs pirates. Then we note that it's the same old same old at Microsoft, with the EU staff being urged to refuse bribes in the form of Windows and Office licenses. Finally we note that despite Mozilla flying the flag for user privacy, why would any companies respect the \"do not track\" option?

    \n

    In our discussion this week, we focussed on the plight of Game; the video game specialist chain in the UK who went into administration this week, where they went wrong, and if it's inevitable and just a sign of the times.

    Fear not Dann has not decided to branch and do a plumbing show. Rather he sticks with the plan and brings us yet another excellent explanation of a common unix utility, namely wc

    \n\n

    \nhttps://www.linuxintheshell.com/2012/04/24/episode-005-wc/\n

    \n\n

    Ever want to know how many lines are in a file? How about how many words are in a file or even how many characters? Well then the “wc” command is just for you. The “wc” command, short for word count, is a very simple command that will print “new line, word and byte counts for file specified, and a total count for all files combined if more than one file is included.”

    \n

    Consider the following little ditty:

    \n

    the linux wc command
    \nfor those not in the know
    \nstands for word count and
    \ndoes a lot you should know

    \n

    It counts lines and words and bytes
    \nproducing output on site
    \nquickly giving you the numbers
    \nwithout any blunders

    \n

    Executing the following command:

    \n

    wc poem.txt

    \n

    Results in the following output:

    \n

    9 40 215 poem.txt

    \n

    To break it down:

    \n
      \n

      \nDeep geek will be taking some time off from recording Talk Geek to Me, to upgrade some of his technology. He should be back in June or July.\n

      \n

      \nDavid Whitman says that the HPR conference kit, such as it is, has arrived safely and in time for LFNW (https://linuxfestnorthwest.org/). He has built quite a display to go behind the table, and he'll probably draw quite a crowd. He's making good use of Ken's presentation slides too, and those will play on a loop at the table. LFNW is going on as we record this, so we hope to hear back from David this month.

      \nGoogle Drive Released, Not So Much For Linux

      \n

      The long rumored on line storage from Google has been announced as a reality. Unless of course you are running a Linux desktop. I don’t know but if it where me and my entire business was built on top of Linux that it might be the first client I produced. They have an Android client how difficult can it be.

      \n

      Every subscriber will get 5GB for free with the opportunity to upgrade to any of the following plans.

      \n

      Storage       Monthly Rate
      \n25 GB           $2.49
      \n100 GB         $4.99
      \n200 GB         $9.99

      \n

      You can access the service at dirve.google.com. Although it is currently not ready for me (insert picture). It will support over 30 file types that you will be able to open right in your browser. It will integrate with Google+, Gmail, and Google Docs. You can share files or folders with anyone, and control whether they will be able to view, edit or comment on your stuff. Extensive search capabilities including OCR for pictures and scanned documents. And my favorite feature document rollback for up to thirty days. Google Drive tracks all changes so that when you save a document, a new revision is saved. You can look back as far as 30 days.

      Slackware Alive And Well Despite Rumors

      \n

      When the main website for Slackware went down the rumor mill went into hyper-drive. These Discussions where hot and heavy on LinuxQuestions.org and DistroWatch. The discussions very quickly shifted from website problems to the long term viability of Slackware. This was compounded by Eric Hameleers, a top Slackware contributor, when he posted this early in the LinuxQuestions discussion “Old hardware, lack of funds…”. I am sure that it was not his intended effect but this was like throwing gasoline onto an already raging fire. The conversation quickly veered into the what can be done to save Slackware land.

      \n

      The fires where then fanned even higher when Caitlyn Martin, developer of Yarok Linux, made this statement on Distrowatch disparaging the long term viability of Slackware:

      \n

      “You remember that comment about my involvement in the development of a Slackware derivative? Forget it. We’re already discussing about delaying the release and rebasing off of something with a more secure future,”

      \n

      This successfully torqued off a large number of people in the discussions on both websites. She responded to these comments by maintaining her stance that she was only concerned about upstream stability. The positive to come out of Martin’s comments was that it prodded Hameleers into clarifying his comments:

      \n

      “The slackware.com server is down. This is a technical malfunction. It costs money to do something about that. Something will be done about that server, but if it takes a while, it is most likely caused by prioritizing and finances. Slackware was without its own web server for a long time in the past. And still active are ftp.slackware.com and connie.slackware.com, so what’s the big deal?

      \n

      This turning of the rumour mill is pretty much unfounded, and I see some of the same old people pouring oil on the fire as usual.

      \n

      There is no reason to doubt the availability, stability and long term viability of Slackware, the distribution. It has not been a one-man show for some time, the development effort is substantial and plainly visible in the ChangeLog, and there are no plans to switch to another development model or even ditch the distribution.”

      \n

      Hameleers went into greater detail about Slackwares finacial situation on LinuxQuestions:

      \n

      “It’s not that difficult: if everybody suddenly stops buying stuff from the Slackware store, then Slackware will not last another year in its present form–the Store sales are Pat’s income (and it feeds several other people too), but remember, the core team surrounding Pat do not get a penny of these revenues at all. Therefore, the rest of the team is not impacted in any way by Slackware sales figures and we will keep working with Pat on the distribution just like we have been doing for the past years. Look at the ChangeLog–sometimes there is a period of relative silence but that does not mean that no work is being done. Like last week, the updates can come in big gulps. Slackware will not die, its philosophy will not change, the team is dedicated and full of ideas.

      \n

      “If people start chickening out and cancel their subscriptions, then that is a pity. Thankfully, I see lots of other Slackware users who decided that this is a good point to make a donation or buy something at the Store (if their financial situation allows it). Thanks to all of you for ‘supporting the cause.’ And remember–if you can not financially support Slackware, then helping your fellow Slackware users in forums like this one is an invaluable form of support as well! Slackware will not die because of financial issues, it will die if all of its users leave.”

      \n

      As Hameleers points out a project like Slackware can never really go away as long as there is a strong community around it. Even if the project folds financially and Patrick did not transfer the copyrights on Slackware to the community it would continue under a different name. However for now there is absolutely no indication that any of that is either in the near or distant future.

      Hungarian Government Solidifies Commitment To ODF

      \n

      Last year the Hungarian government announced that from April 2012 forward all government documents needed to be produced in an internationally recognized open document standard. To further this commitment they are going to invest 370 million HUF (Hungarian Forint) which is approximately 1.7 million USD in applications that utilize the open document format (ODF). The two main beneficiaries of this investment will be the Department of Software Engineering at the University of Szeged and Multiráció, an open source development company.

      Multiráció developed an open office suite, originally based on OpenOffice.org, called EuroOffice. they are now going to produce a version for tablets and improve the collaborative functions within EuroOffice. Kázmér Koleszár, a developer at Multiráció, said that the development responsibilities would break out like this:

      \n

      “The University of Szeged will do the quality assurance and usability related research and tool development. Multiráció will develop the office application and work on several extensions.”

      \n

      All I have to say is good on you Hungary I wish that countries like mine would do more to push open formats. I have even considered suing entities like may state government for their continued use of proprietary formats on their websites.

      Less Than 25% Of OSS Used In Corporations Managed Correctly

      \n

      Sonatype released the results of a recent survey showing that 500 out of 2500 respondents said they were locked down to only use corporate approved components. Only 49% said that their companies had a policy in place. Then 63% indicated that their corporate standards where not enforced or that they did not have a policy.

      \n

      Sonatype also noted that the use of open source components is on the rise. Almost 80% of respondents said they used open source tools regularly. Around 50% have migrated to an open source development stack. Also over 65% claimed to contribute to open source projects.

      \n

      In their press release Sonatype said this about the use of open source:

      \n

      “Key to modern development practices is the use of open source components to build mission critical applications,”

      Red Hat, SUSE, And IBM Form Partnership While Canonical Stays On The Sidelines

      \n

      IBM’s new POWER server line will be available with either Red Hat or SUSE Linux but not Ubuntu. After more than a year in development IBM rolled out their new POWER server systems and solutions. These machines are Linux specific utilizing the POWER7 processor-based hardware. These machines are targeted at midrange to large range enterprises. they are designed for big data analisis and delivering open source infrastructure services. Canonical chose not not to offer their server product on these units. Coould that be due to a fear of having to actually support an enterprise class customer.

      \n

      This is how IBM envisions the use of this new server line:

      \n

      “The new PowerLinux Solutions and supporting systems are designed to provide customers with lower deployment time and costs, and greater performance, dependability and workload density than competitive x86 platforms at similar price points.”

      \n

      So where was Canonical in all of this? they had been working with IBM to deliver Ubuntu on IBM’s System p mini computer. That partnership however floundered into nothing.

      \n

      Here is how Mark Shuttleworth, Canonical’s founder, spun the announcement:

      \n

      “We don’t support POWER because, by mutual agreement with IBM, there’s little to no overlap between the POWER user base and Ubuntu. People are choosing Ubuntu for farms of commodity servers, and POWER has been adopted for highly-specialized mission-critical roles. If IBM ever wanted to reach either the cloud or bulk computing market with POWER, then I expect the stats above would be relevant for their choice of OS, because they reflect the real choices of those markets.”

      \n

      Hunh? I had a hard time following that statment but what I think it boils down to is this. IBM and Ubuntu agree that Ubuntu would be hard pressed to actually support a large enterprise customer. IBM, Red Hat, and SUSE still believe that their is a market out there for the big machine built on quality hardware. As opposed to large farms of x86 systems trying to do the job of a bigger machine.

      \n#da12bb #HPR
      \nIn todays show Ken talks to Chris Conder of the Broadband for Rural North (https://b4rn.org.uk/).
      \n\"A\n

      \n

      \nLocated in the very pretty but the rural Forest of Bowland in Lancashire in the UK, and tired of putting up with slow 'broadband' they decided to put together their own network. They tried shared wifi, 3 and 4G mobile networks, MMDS and Satellite yet all proved to be unreliable.\n

      \n

      So over tea and cake they came up with a plan.

      \n
        \n
      • A 240 Kilometer (150 mile) plan.
        • \n
      • A 1 gigabit (1000mb/sec) fiber optic connection plan.
        • \n
      • A let's give a connection to every one of the 1700 homes, farms, schools, churches and businesses, in the area plan
        • \n
      \n

      And while they were at it they designed it to be:

      \n
        \n
      • redundant with a dual homed backbone direct to the UK's Internet exchange
        • \n
      • upgradeable with ducts large enough to take multiple fibers
        • \n
      • laid through some of the most rugged, mountainous area of Lancashire to get to the people that need it most. (And let's be clear here, nothing to do with the fact that they will need to use dynamite to blast their way through the rocks.)
        • \n
      \n

      \nChris herself has lived in the Lune Valley for many years and is married to a farmer in Wray. She has been involved with the community in many roles over the years; for instance school governor and chair of Wray Endowed school during the eighties and early nineties and more recently supporter of a number of rural broadband projects. In 2002 she began campaigning for rural broadband and over the next few years helped establish a wireless network around Wray and a satellite network for rural farms. A founder member of Wray Com Com in 2003 (https://www.wraycomcom.org.uk/) and Wennet CIC in 2005 (https://www.wennetcic.co.uk). She is a pioneer of self installation fibre and a regular speaker at broadband events on the topic of rural broadband and DIY fibre build.
      \nShe is also a 'online animator' for high speed broadband for Europe. She posts on the blog (https://daa.ec.europa.eu/group/2/content\") and your feedback would be MORE than welcome.

      \n

      \n

      \nLarry the CrunchBang Guy is Larry Cafiero, 54, who runs Redwood Digital Research in Felton, California, which provides Free/Open Source Software solutions for the small business/home office environment. He has been an advocate for Free/Open Source Software (FOSS) since the fall of 2006. Toward the end of 2006, he had an epiphany or satori regarding the social, philosophical, political and economic benefits of using FOSS on his favored hardware, which at the time consisted of the Mac PowerPC platform (although he has warmed up to Intel machines as of late). He organized a project to promote GNU/Linux which turned out to be the Lindependence events in Felton, California, in 2008. Larry’s brush with fleeting fame came in 2006 as the Green Party’s candidate for Insurance Commissioner in California (270,218 votes, 3.2 percent). He has been using CrunchBang on a regular basis since July 2011.\n

      \nOn Linux For The Rest Of Us #74 - The Legistrative Session, one of our correspondents Mr. Gadgets, called in the following question. The segment begins at at 01:00:30 and in it he describes a conversation about the four freedoms where someone whose opinion he respected stated \"the four freedoms only cover programming. It is only the code that is covered in the four freedoms\".\n

      \n

      \nFor those of you who don't know The Free Software Definition boils down to the following rules:\n

      \n
        \n
      • Freedom 0: The freedom to run the program for any purpose.
        • \n
      • Freedom 1: The freedom to study how the program works, and change it to make it do what you wish.
        • \n
      • Freedom 2: The freedom to redistribute copies so you can help your neighbor.
        • \n
      • Freedom 3: The freedom to improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits.
        • \n
      \n

      \nIf you read the The Free Software Definition, then yes all the references are to \"software\" only....
      \n...that is of course until you get to the section Beyond Software, in the same document, which states:
      \n

      \n

      \n\nSoftware manuals must be free, for the same reasons that software must be free, and because the manuals are in effect part of the software.\n
      \nThe same arguments also make sense for other kinds of works of practical use - that is to say, works that embody useful knowledge, such as educational works and reference works. Wikipedia is the best-known example.\n
      \nAny kind of work can be free, and the definition of free software has been extended to a definition of free cultural works applicable to any kind of works.\n      \n

      \n

      \nSo in summary, as HPR is now released under a Creative Commons Attribution-ShareAlike 3.0 Unported lisence, any shows that provide useful knowledge, such as educational works and reference works are covered by the four freedoms.\n

      A short report from the HPR Table at LinuxFest Northwest

      \n

      \nFrom: David Whitman
      \n
      \nA friend from work got interested in going to the LinuxFest and helped at the table - Much thanks to Brad Coffey. We got set up on time and were well received. We had a great run on our swag and ran out of the HPR pin buttons by closing on the first day and handed out quite a few informational cards.The little business cards were really a hit also. Lots of good conversation and exposure for HPR. There was a constant stream of people coming by. I have four interviews on my various recording devices and should be able to get about four to six more from the sign up sheet that was available on the table. With a bit of planning and a more formal interview 'track' (using an appointment schedule and a designated room or area) I am sure a well staffed HPR table could easily get 20 interviews at this fest. Of course I will be interested in\nseeing if any of the many we talked to produces and post their own show. There was interest. I sensed that many of the speakers would have loved the extra exposure. HPR is probably becoming the embedded reporters of Linux Fests. The unofficial count of attendees that I heard was at \"over 800\". The table kit is ready to be shipped to the next venue. My intent is to put together a vertical layout canvas that can easily be shipped and set up as a backdrop and utilize a series of those 20 by 30 photo posters available at Costco Photo. This however will have to wait until after my annual spring fling of shutdown work that begins on May 5 and takes up to 3 weeks to complete. I'll post a G+pic of the backdrop we used at this fest. Best swag for me - a Tux 2012 bumper sticker from Pogo Linux. Look for a scan of this on G+ in the near future.\n
      \nThanks to the HPR community for the opportunity to represent the show. It was much fun.

      New Banner

      \n

      \nThere was a very kind offer by David Whitman to sponsor a tall free standing banner and the call was put out for a design. Here is the final outcome of the discussions.

      One Community supporting another

      \n

      \nBack in episode https://hackerpublicradio.org/eps/hpr0980/ Broadband for Rural North, I suggested that people could sponsor a meter of cable for their project to show your support. Well they have gone ahead and done it\nhttps://b4rn.org.uk/sponsor-a-metre. It's £5 for a meter or Special offer, 5 names for £20.\n
      \nI will also extend the donation deal from the holiday period, so that anyone who donates to this gets some HPR swag when it's available.\n

      \n\n

      Explicit Tag

      \n

      \nThere was a discussion on whither we should have a ban on swearing. We already have a iTunes explicit tag so assume that all shows may contain controversial material. Hosts are free to add a \"safe for work\" warning or any other warning they wish to the shows.
      \nWe may add an option in the upload forms to support this on a show by show basis.\n

      Episode 1000 and 1024

      \n

      \nA note from Fifty OneFifty
      \nThis is a list of all the TWaTech correspondents that I either I had no contact information for or the best e-mail I could find bounced back:
      \n\nAdam, Coder365, DarkShadow, Draven, kotrin, Lunarsphere, MrE, spaceout, ThoughtPhreaker, killersmurf, Dominic Uilano, livinded, J-Hood, skyre, kitche, plexi, Scedha, Will Jasen, phizone, operat0r, blackratchet, merk, and Dr^ZigMan\n
      \n
      \nI'd like you to mention the handles and maybe the community can help us make contact with them. I sent the invitations to the first year HPR correspondents today. One message bounced back, but I can contact that person by other means. I'd also like you to read the message below and consider posting it on the site.\n

      \n

      \nHacker Public Radio is inviting the participants in podcasts and organizations that proceeded HPR and led to it's creation to join a recorded panel discussion on HPR's origins and history. We are reaching out to TWATech, BinRev Radio, Radio Freak America, Podfert, the Infonomicon Computer Club, and contributors to the first twelve months of HPR. Our discussion will be recorded via the LinuxBasix.com Mumble server (mumble.openspeak.cc , Port: 64747) and be released as HPR episode 1024 (Stankdawg's idea). Episode 1024 should fall on 5 July, but we would like to shoot for recording the panel about two weeks before hand. In case of technical or other unforeseen problems on the primary recording date, a two week lead would give us time to regroup and make a second attempt. The date and time will be set to make it convenient for the greatest number of people who are willing to participate to join in. Connections over Skype and SIP phone via Asterisk are possible, but it would be simplest for everyone to try to use the open source Mumble client.\n
      \nIf you decide to join in (and we hope you will), please include the time zone of where you will be in mid June, especially if you are outside the continental United States. If there are dates, days of the week and/or times you would like me to avoid scheduling the panel (i.e., \"I will be gone June 19-21\", \"I could only do it on a weekend\", \"only after 8PM\", \"only before 10PM\") I would like to know that as well. You may contact the organizers at ep1k@HackerPublicRadio.org\n

Any shows in there would follow the\nregular scheduling rules\nhttps://hackerpublicradio.org/calendar.php#scheduling_rules.\n\nIt's a discussion - let your voice be heard\n\nKen.\n\nFrom: kevin granade\nDate: Mon, 30 Apr 2012 13:27:25 -0500\n\nI think this is a good idea, in fact, perhaps people could request a\npriority level?  Most show ideas I have could sit in the queue for a while,\nand I'd be happy to let more timely shows move ahead.\n\nFrom: lostnbronx\nDate: Mon, 30 Apr 2012 16:02:15 -0700\n\nI Think a certain day could easily be put aside as a day for topical\nor timely episodes.  It might be best, though, not to announce it as\nbeing such to the general listenership, so that if there's a dearth of\nnews-type shows one week, another type of ep can be dropped in without\nany need for a special announcement.\n\n\nFrom: Kevin O'Brien\nDate: Tue, 01 May 2012 16:03:11 -0400\n\nI'm going to try this again since I hit the wrong button last time and\nsent it Ken personally instead of to the list.\n\nJust for the sake of discussion it occurs to me that while DeepGeek is\non a hiatus for the moment, he had a weekly news spot every Friday. I\ndon't know if there is any understanding that he will come back and\nresume his spot, but if so, would this mean 2 days a week reserved for\nnewscasts? That might be a bit much.\n\nRegards,\n\n--\nKevin B.

Where else can so many people share\ntheir ideas.  The strength of HPR is anything and everything is\nacceptable content as long as it is of interest to hackers.  But as I\nlook back over the history of HPR, most attempts to add structure or a\nrigorous schedule just haven't worked.  The one exception is the\ncurrent policy of syndicated Thursdays.\n\nI have to agree with cobra2. If people want to do news shows, that's\ngreat.  But IMHO, unless it is really important (event announcements)\nit should take it's place in the queue with everybody else.  Shows\nlike /dev/random are awesome, but it's not because of the news they\ncover.  There awesome because the guests are hilarious.  The stories\njust give them something to talk about.  Even when their news is\nweeks old, they are still fun to listen to.\n\nSo, there's my two cents.  For what it's worth from a long time\nlistener who has never contributed a show.\n\nTodd\n\nFrom: Jason Dodd\nDate: Fri, 04 May 2012 03:56:46 -0400\n\nWhy reserve any day?  One of the things I like about hpr is I don't know\nwhat to expect.  The more I know what to expect I think the less I'll\nlike it.\n\nFrom: Kevin O'Brien\nDate: Fri, 04 May 2012 12:02:29 -0400\n\nI'm a great believer in moderation in most things. I look forward to\nmany of the scheduled shows, and the ones that may not appeal to me\nprobably appeal to lots of other folks. But I would favor not adding to\nthem because part of the charm of HPR is not knowing what to expect.\nAbout one time out of every 30-40 shows I will hit the \"Next\" button on\nmy MP3 player, which is not bad, really. But I would rather the\noccasional show that does not appeal to me than missing out on the gems.\n\nRegards,\n\n--\nKevin B. O'Brien\nzwilnik@zwilnik.com\n\"A damsel with a dulcimer in a vision once I saw.\"\n\nFrom: Cobra2\nDate: Fri, 04 May 2012 13:20:18 -0300\n\nI'm not in favor of dropping rule #2. Unless it is going to be used to\nsyndicate some sort of news show. News is not content it's just a\nfiller if there is nothing else left to talk about.\n\nI know the rules state of interest to hackers. But the history of HPR\nand TWAT has been mostly shows that dig deep into a piece of software\nor hardware or are a detailed how to. Shows that have a fairly long\nshelf life not something that can be outdated if a week or two passes\nby.\n-- cobra2\n\nFrom: Frank Bell\nDate: Fri, 4 May 2012 18:53:41 -0400\n\nI tend to agree with this.\n\nAlso, as someone who is very new here, I am concerned that, if many\nslots are filled up with scheduled shows, aspiring contributers miight\nbe dismayed to find that a show uploaded, say today, might not be\nposted until late June or July.   This can be a demotivator.\n\nAs an aside, I can count on both sets of fingers the number of shows\nI've hit \"Next\" on.  The variety of HPR is one of its main attractions\nfor me.  Usually, when I do hit \"Next,\" it's because the topic is so\ntechnical (say, a programming language) that I can't follow it.\n\nOnce or twice--no more than that--it has been because the premise of the\nshow was nonsensical--nevertheless, thanks to HPR, I got to hear and\nevaluate the premise, which, without the HPR's variety, I would not have\nhad the opportunity to do.\n\nFrom: Ken Fallon\nDate: Sat, 5 May 2012 09:14:08 +0200\n\nOK All,\n\nWhat I'm hearing is that the following shows will be dropped into the\nregular First come First Served Queue:\nTalk Geek To Me News.\nDev Random\n\nThe following show will be dropped from Syndicated Thursday.\nSunday Morning Linux Review.\n\nIs this correct ?\n\nKen.\n\nFrom: dg\nDate: Sat, 5 May 2012 07:09:38 -0400\n\nHi, Guys,\n\nJust wanted to say that whatever you decide is fine by me. The news\nshows I submit to HPR are actually \"one half\" of my regular show. That\nis to say, I do a special tech-only version of my full world+tech news\nshow for HPR.\n\nTherefore, in theory, a news-lover would be able to go to my website\nand subscribe via RSS and get my shows rather quickly, if they so\ndesired.\n\nHowever, I also need to point out two more things.  First, I agree with\nanother poster that a distinction needs to be made between a show that\nis about the guests, with current events thrown in as something for\nthem to comment upon; as opposed to my show which is purely about the\nstories (I do rarely make editorial comments, but I try to keep my\npersonal opinions to a minimum.)\n\nSecond, I disagree with yet another poster that what I offer should be\n\"filler\" and qualifies as something \"that can be found almost\nanywhere.\" The whole point of all the stories I cover is that a) they\nare not covered by the mainstream media and b) they are, nevertheless,\ntimely and important news. In regards to this opinion, I ask you to\nconsider whether or not it is widely held amongst the general\nlistnership, which to I understand is not entirely present on this list.\n\nThanks for considering,\n---\nDeepGeek\n\n\nFrom: Fifty OneFifty\nDate: Sat, 5 May 2012 12:51:29 -0500\n\nI our discussion of whether we want to keep syndicated shows, we should not\nlose sight of the fact that last year Ken was really scrambling to find\ncontent to keep HPR broadcasting on a daily basis.  While I think most of\nthe shows in syndication would understand, I hate to put Ken in the\nposition of saying, \"Thanks, but we don't need you any more\".  As for\nvariety, maybe we consider offering syndicated shows a limited run, 2 or 3\nshows, not in consecutive weeks, as an introduction to our listener base.\nAfterwards it would be incumbent on our listeners to add those shows to\ntheir queue if they like what they hear.  It will also be up to\ncontributors and listeners to look for new shows that we can invite for\ntemporary syndication, like pokey has with https://distributedpodcast.com.\n\nFiftyOneFifty\n\nFrom: David Whitman\nDate: Sat, 5 May 2012 11:14:31 -0700\n\nI posted this on Henry Patrick Riley (Goggle+)\n\nWhat about making a MEGA syndicated day and combining 2 or more shows\ntogether with intro music between and posting the run time when one show\nends and another begins? Rotate the order which show airs first.\n\nThe following is more comments not on G+:\n\nI want produce some 'casual' shows  that could go into an 'emergency' queue\nin case there are times when the regular queue get close to empty. Things I\nwant to share, but they are not time critical and I am willing to have HPR\nbank (such as How I found Linux, How to run a car in the Auto-X, A vacation\nto Moab, Utah, Troubleshooting an MR2 using a volt/ohm meter etc. My idea\nis that as soon as the emergency queue gets a month's worth of shows they\ncould be put out periodically into the regular queue. They could be tagged\nwith a 1-5 tech rating and the more techie ones used first.\n\nHow about having 2 parallel  tracks? or 3? HPR News, HPR Command Line, HPR\nProjects, a weekly show track just for news....\n\nAll good and fine - I have 3 shows that need editing to help contribute to\nthe problem.\n\nThanks to all the HPR community members and admins. I love the show.\n\ndavidWHITMAN\n\nFrom: Frank Bell\nDate: Sat, 5 May 2012 15:28:05 -0400\n\nOn Sat, 5 May 2012 12:51:29 -0500\nFifty OneFifty wrote:\n\n> I our discussion of whether we want to keep syndicated shows, we should not\n> lose sight of the fact that last year Ken was really scrambling to find\n> content to keep HPR broadcasting on a daily basis.\n\n(snip)\n\n>  As for\n> variety, maybe we consider offering syndicated shows a limited run, 2 or 3\n> shows, not in consecutive weeks, as an introduction to our listener base.\n\nI think these thoughts have a lot of merit.  I rather enjoy learning about\nnew shows through Syndicated Thursdays (I had not heard of the Sunday Morning\nLinux show until HPR introduced it to me).  Also, I must say I have heard\nsome syndicated shows that I do enjoy, but not enough to actually subscribe\nto, so I find the idea of maintaining variety appealing..\n\nMy concern is that, if there are too many dedicated days, the dedicated days\ncould turn into a regular line-up.\n\nJust my two cents.\n\nFrom: Patrick Dailey\nDate: Mon, 7 May 2012 23:17:11 -0400\n\nThis may be the \"healthiest\" discussion that I've ever seen on the HPR\nmailing list, and I love it. I want to thank each and every person\nsubscribed for keeping the conversation respectful, and on topic. Most\nmailing lists that I've seen could not have accomplished that.\n\nAs to the scheduling multi-lemma, I have a few thoughts that I would thank\nyou all in advance for considering:\n\nWe have the kind of crisis that we've always wanted, namely: we have too\nmany shows. This is an opportunity that I don't think we should squander.\nAt the same time we're trying to establish a scheduling policy that an\nunmanned system can obey. The goal, as I see it, is to create rules that\ncan deal with an abundance of shows without wasting them. Right now what we\nhave is a scheduling policy that worked very well with a lack of shows, and\nin fact it helped to replenish them. So I believe that we need either: one\nset of rules that can cope with either situation, or two sets of rules and\na way for a deterministic system to identify and transition between them.\nPlease chime in on this if you are good with policy.\n\nAs I see it, at least part of what we're dealing with is a resource\nmanagement problem. People create content for us, and sometimes they assume\nthat it has an expiration timeframe. Some content simply must be used\nbefore it's creator feels that it has expired, or we can expect that that\ncreator will seek other venues in which to publish their content. We need a\nway of distinguishing \"perishable\" content from \"non-perishable\" content.\nWe also need a way of putting a date on the perishable content. If you have\nexperience with user feedback systems, we could really use your help\n(especially) with this part.\n\nSince identifying potential problems without offering solutions is just\nbitching, I have a couple of suggestions.\n\nSyndicated Thursdays and \"timely content\"\nI for one, am grateful to the shows who have allowed us to fill holes in\nour que with their content. While the syndicated Thursday slot was\noriginally implemented out of necessity, I feel that it is an overall plus\nto continue the practice. We have developed friendly and mutually\nbeneficial relationships with other podcasts that I would be hesitant (to\nput it mildly) to sever, and there are other great podcasts that we don't\neven know about yet. I agree with Frank Bell in that I think the syndicated\nThursday feed is a great discovery tool, and I'd hate to loose it as such,\nbut I also see these shows as friends, and I want to make sure that we\ntreat them like it. I don't think it's in anyone's best interest for us to\nabandon that kind of relationship, or the content that has so generously\nbeen offered to us. If (and only if) there is a \"Timely news show\", I would\nlike to see it get the Thursday slot, but in order for the syndicated show\nto not be wasted, I would like to see that show bumped to Saturday.\n\nScheduled HPR exclusive shows and normal que shows\nI think if people commit to producing scheduled content before they record\nit, and live up to that commitment, that we should honor that commitment.\nPerhaps there needs to be some limit to the number of pre-schedulable slots\nper week and/or month that we make available, so that there is still room\nto play shows from our normal que, but we-as a group decided to ask people\nto produce content for us, and several people have stepped up and\ndelivered. Perhaps this is a situation where more than one show should be\nposted per day. I don't know.\n\nWhile it's easy for me to sit here and suggest these things, I don't think\nthat it's fair for any of us to vote for posting more than five shows per\nweek unless we are committing to posting more than the requested \"one show\nper year\" if the que ever gets low again.\n\nLastly, I believe that new hosts should continue to get the first\nunscheduled slot. This is critical to getting new people to contribute, and\nto return as hosts.\n\nIf I'm wrong, or out of line, or TLDR, or whatever... feel free to say so.\nI can take it.\n\npokey\n\nFrom: \"Frank Bell\"\nDate: Tue, 08 May 2012 13:21:53 -0400\n\nOn Mon, 07 May 2012 23:17:11 -0400, Patrick Dailey\nwrote an extremely thoughtful and useful post from the \"be careful what\nyou wish for\" department:\n\n\n> Syndicated Thursdays and \"timely content\"\n\n> loose it as such, but I also see these shows as friends, and I want to\n> make sure that we treat them like it.

I wasn't here when the goal of five\ndays a week was set, but I'm inclined to think that it was intended to be\na goal, not a limit.\n\nI would suggest, as an aside, that the scheduling rules could be displayed\nmore prominently.  Currently, they are at the bottom of the calendar.  I\nthink prospective or new (like me) hosts should have their attention drawn\nto them more forcefully, perhaps by giving them their own page linked from\nthe front page and linking to them from the calendar and from the\n\"Contribute\" page.  I also suggest changing the terminology from \"rules\"\nto \"guidelines\";  that's not just PR softening of a phrase, for they are\nguidelines as exceptions can be made.\n\nIt may also be useful to suggest that new hosts glance as the calendar to\nsee when their available slots.  I would also like to see a friendlier\ncalendar, meaning one that looks more like a wall calendar.  If you all\nwish, I would be happy to explore the WordPress plugins to see what I can\nfind.\n\nI support continuing the practice of bumping new hosts up in the queue.\nIt's a recognition of effort and a motivator.  Frankly, I found it a blast\n(if an intimidating one) to look at my podplayer and see my own name\nlooking back at me.\n\n> Perhaps there needs to be some limit to the number of pre-schedulable\n> slots per week and/or month that we make available, so\n\nThis might also be a good idea and it speaks to my concern of HPR's\nturning in to a line-up of  a few scheduled shows, rather than a platform\nthat's open to newbies like me.\n\nOn the other hand, many persons have responded to the need for shows that\nKen sounded last fall, not only with shows, but by airing promos on their\nown podcasts and websites, which leads to exposre which leads to shows (by\nthe way, I think this flowering of support is a tribute to HPR and to the\nplace it has amongst the community).\n\nThe flowering may yet wither and need to be watered anew.  In other words,\nonce the enthusiasm wears off, Ken might be having to appeal for shows\nagain.\n\nIn other words, I agree with some sort of limit and I lean towards a\nmonthly one, but have no idea what would be a reasonable one.  If I were\nto try to word that as a guideline, it might come out like \"the number of\nscheduled shows and the intervals between them that HPR can commit to is\naffected by the number of submissions\" and leave it at that--that allows\nwiggle-room for adjusting to the realities of now.\n\n> that there is still room to play shows from our normal que, but we-as a\n> group decided to ask people to produce content for us, and several\n> people have stepped up and delivered.

      \n A quickie episode by Windigo\n that covers a fix for the \"Sticky Keys\" bug in Minecraft on Linux.\n

      \n

      \n The \"Sticky Keys\" bug causes the Minecraft client to act as if a button\n hasn't been released when it has - which causes your character, Steve, to\n suffer some awful consequences as a result (depending on what situation\n you are in when the bug occurs).\n

      \n

      \n Upgrading the LWJGL libraries/drivers that\n come with Minecraft usually fixes this bug. To upgrade the drivers, do the\n following:\n

      \n
        \n
      • \n Download an updated version of the LWJGL libraries\n
          \n
        • \n LWJGL 2.8.0\n - Not the latest release, but worked great for me\n
          • \n
        \n
        • \n
      • \n Copy the following files from lwjgl-2.8.0/jar/ in the zip\n file you downloaded to /home/[youruser]/.minecraft/bin/,\n replacing the existing files there:\n
          \n
        • jinput.jar
          • \n
        • lwjgl.jar
          • \n
        • lwjgl_util.jar
          • \n
        \n
        • \n
      • \n Copy all of the files from lwjgl-2.8.0/natives/ in the\n zip file you downloaded to\n /home/[youruser]/.minecraft/bin/natives/, again replacing the\n existing files there\n
        • \n
      \n

      \n If you still encounter issues with the new versions of the libraries, try a\n newer or older version until you find one that works with your system. 2.8.0\n happens to work for my setup (Debian Stable w. Sun Java), but YMMV - your\n Minecraft may vary.\n

      \nRadio FreeK America was a Hacking and Phreaking related Internet Radio show primarily based out of Arizona and initially hosted by dual_parallel. The title is often abbreviated to RFA in text.\nThe first episode appeared on February 20 2002. It lasted forty five minutes and twelve seconds. The last episode aired on February 20 2004 and lasted two hours, forty two minutes, and twenty nine seconds. During these two years, Radio FreeK America had a total of ninety nine shows (including a lost episode #76, of which no file exists).\n

      History

      \n

      \ndual_parallel presented the idea for the show to two individuals at the [Phoenix 2600] meeting, Rax and Kondor in December of 2001 or January of 2002. \"dual\" (as he later came to be known as) recorded the first \"segment\" of Radio FreeK America (RFA) on 2/2/2002. The first show was \"broadcast\" via RantRadio on 2/20/2002. The first several episodes were co-hosted by Rax and Kondor.\n

      \n

      \nThroughout the series, other guests such as StankDawg (who would later go on to develop [Binary Revolution],) Meme, Zapperlink, bland_inquisitor, Bi0s, and W1nt3rmut3, as well as a few other notable guests from the Telecommunications Industry, who remained nameless, became common guests and co-hosts.\n

      \n

      \nThe show originally was recorded and encoded to mp3 format and released on the website every Wednesday. Around episode nine, streaming began offered by Rant Radio and went out every Tuesday at 19:00 EST.\n

      \n

      \nRadio FreeK America's website, [Old Skool Phreak], features a \"Phreak Photo Gallery\", \"Hacker Art Gallery\", text files, video files, and the download section for Radio FreeK America.\n

      \n

      \nThe radio show, through its success, inspired many other Internet Radio shows, such as Binary Revolution and Default Radio. Dual attributes the inspiration of the show to other hacker-oriented Internet Radio programs like In the Now, Hacker Mind, Off the Hook, and Rant Radio.\n

      \n

      \nRadio FreeK America had been the home to Project Walmart Freedom, a community effort to explore (in great detail) the inner phone system of Walmart stores, as well as codes, signals, procedures, and terminology usually only known to Walmart employees exclusively. Some information was known only to upper management as well.\n

      \n

      \nSoon after the last episode aired, the website went offline for a brief period of time. Oldskoolphreak.com had been replaced by a website featuring information on phreaking with PDA's. That site had been moved to PDAphreak.biz. (As of September 7 2005 PDAphreak.biz was no longer online.) Oldskoolphreak.com is still maintained by Natas, despite the lack of dual and lack of continuation of RFA.\n

      \n

      \nOn the last episode, dual gave his reasons for ending the radio show to start a new one called Hacker Public Radio. This never came to be though, and dual has made very few appearances since.\n

      \n\n

      Content

      \n

      \nThe theme of Radio FreeK America kept true to the hacking spirit: to learn and explore, as well as keeping knowledge free. The name Radio FreeK America was coined by Rax and has several layers of meaning. The term \"FreeK\" is spelled with a capital \"K\" to stand for knowledge, and the term was to be understood as \"keep knowledge free\", hence \"FreeK\" or \"Free Knowledge\". It was a common saying of Rax at the end of the show to say \"keep knowledge free.\" Radio FreeK America is also a play on Radio Free Europe, a broadcasting organization funded by the United States to promote democratic values in other nations. Radio FreeK America sought to inspire and present the values, concepts, and idea of the hacking/phreaking community.\n

      \n

      \nAlong with \"keep knowledge free\" was the tagline \"be the media,\" which was coined by Jello Biafra. Here, dual stresses the necessity of alternative media, and that having only a few sources of media is biased and not effective on covering information from all perspectives. Also, alternative media can be more tailored to suit its audience. With this, dual encouraged more people to start internet radio shows.\n

      \n

      \nThe show revolved around the hacking and phreaking scence extensively. Covering issues from wardriving and its off shoots, urban exploration, Linux, computer security, phreaking, freedom of speech, legal issues, some political issues, amateur radio, and anything that could be deemed relevant to the hacking culture abroad.
      \nDual, from the start, intended to make it a show about the listeners and about the community. The show carried a variety of topics that the hacker community would be interested in. The first episode started with dual playing a recording of a trashing session at a local telco Switch. The show also had a segment at irregular intervals called \"Phreak News\" where dual would play a 25¢ tone from a red box and speak about issues relevant to the phreaking community. \"Dual's Adventures\" was a segment just as irregular as Phreak News where dual would talk about opportunities dealing with technology that arose while he was in an urban setting, usually a store.\n

      \n

      \nUrban exploration was also a common part of Radio FreeK America, which often had dual playing his audio-recording adventures into various tunnels and basements. It was also common for dual to make several phone calls per episode to \"interesting\" numbers to see what could be learned. Calling card information was occasionally given out and posted on the site for the purpose of listeners to use for whatever they felt like. Listeners' email were read at the beginning of nearly episode as well, often with a thanks from dual, and a brief talk about the importance of community action, another driving force behind Radio FreeK America.\n

      \n

      \nRadio FreeK America initiated a fundraiser to send money to the Electronic Frontier Foundation, stressing the need to keep knowledge free and keep your right to freedom of speech.\n

      \nAn introduction to the Nix package manager and related projects:\n

      \n

      \nNix is a purely functional package manager. This means that it can ensure that an upgrade to one package cannot break others, that you can always roll back to previous version, that multiple versions of a package can coexist on the same system, and much more.
      \nNixpkgs is a large collection of packages that can be installed with the Nix package manager.
      \nNixOS is a Nix-based Linux distribution. Thanks to Nix, it supports atomic upgrades, rollbacks and multi-user package management, and it has a declarative approach to system configuration management that makes it easy to reproduce a configuration on another machine.
      \nHydra is a Nix-based continuous build system.
      \nDisnix is a Nix-based distributed service deployment system.

      \nToday we're going to play the audio from a Ted presentation\n

      \n

      \nFrom Wikipedia, the free encyclopedia
      \nTED (Technology, Education and Design) is a global set of conferences owned by the private non-profit Sapling Foundation, formed to disseminate \"ideas worth spreading.\"\n

      \n

      \nThe title of the talk is \"The 8 Billion Dollar iPod\" and the speaker is Rob Reid who is a humor author and the founder of the company that created the music subscription service Rhapsody.
      \nhttps://www.ted.com/talks/rob_reid_the_8_billion_ipod.html\n

      \n

      \nTodays HPR presentation is an enhanced podcast, where we describe any slides that are not explained in the narrative.
      \n

      \n

      \nThis would be a good time to remind you that Jonathan Nadeau is looking for donations for The Accessible Computing Foundation.
      \nThe Accessible Computing Foundation exists to design Free software to help bridge the gap between accessibility and technology. As a nonprofit we will hire developers to create Free accessible software and bring awareness to people's accessible needs around the world.

      About Rivendell with Rivendell

      \n\n

      \nIn this episode I talk about the Rivendell Radio Automation software whilst using the same software to play music and sound.\nThis show was recorded \"as live\" and unscripted. I need a bit more practise as I'd like to use a similar setup to do my own podcast show. Did a bit of normalising and amplifing as the levels weren't that great (another thing to practise)\n

      \n

      \nStuff I forgot to mention:\nTalking about multiple tracks in Carts, you can set each track to only play under certain conditions, such as time or day of the week.\nRDPanel is an appilcation which is a large version of the sound panel in RDAirplay, great to have on a second monitor.\nLogs are playlists which can be saved and loaded an can be generated just by playing music in Airplay or building them manually in RDLogedit or automatically with RDLogManager.\nRivendell can manage more than one radio station if needed and share the same DB.\n

      \nToday we are going to listen to episode 51 of the infonomicon (https://audio.textfiles.com/shows/infonomicon/ ) podcast. Droops had been a regular listener of RFA and emailed their show several times, started his own show Droops Radio which changed to infonomicon radio. \n

      \n

      \nInfonomicon Bumper Music plays until 1:35. Positive feedback about the Infonomicon TV. This is episode 51, which should be almost a year, except it's been more than a year. Podcast Incubator 2.0 is coming, and its code is going to be released under the GPL. Dosman and Droops have come up with the idea of doing a daily radio show: Talk with a Techie (TWAT). No fluff, no nothing, at least five minutes long. Infonomicon won't close because of this. Obfuscated is not a happy camper, but he is alive. 16 of 66 pages in a magazine Droops read was from one magazine. Bob Denver (Gilligan) passed away, and the boat from Gilligan's Island was named after a FCC chairman. AOL is about to be a sucker again, so screw them over. Cyber-looters are registering domains and taking money from hurricane donators: 2500 domains have been registered. Droops is not sure what the solution should be and asks for solutions. People trust Google, but Google can do evil: they're an advertising company. Google is buying dark fiber. Google has all sorts of broadband needs, so they'll likely go after all sorts of bandwidth to bring their services. Droops wishes that Google made blogs an option to not search. There's lots of companies searching nothing but blogs. This hasn't been the greatest show ever, but work is being done on the other shows. This is the shortest Infonomicon ever. Bumper Music plays from 15:42 onward.\n

      \nOne of the major advantages of Google Reader over application based clients is that no matter where you access it from your views are synchronized. Everything you read is marked a read everywhere and you don't have to worry about whither you check your feeds on a desktop PC or on your phone. It truly is the best example of a cloud application out there.\n

      \n

      \nExcept for the fact that I'm not happy with the idea of a complete stranger watching and recording every article I read, how long I read it for, and share that information around to other trusted partners. Remember when your parents/guardians caught you reading over their shoulder ? It wasn't acceptable then and it sure isn't now. Epically when I noticed that my search results changed dramatically after I started following certain feeds. It's just not right and here's why https://www.ted.com/talks/eli_pariser_beware_online_filter_bubbles.html\n

      Getting a list of my feeds

      \n

      \nGoogle should be credited with the fact that they make exporting very easy to do. Thanks to the work of the https://www.dataliberation.org/ team. Who's stated goal is \"Users should be able to control the data they store in any of Google's products. Our team's goal is to make it easier to move data in and out.\"
      \nFor Google Reader this amounts to:\n

      \n
      \nSettings -> Reader Settings -> Import/Export -> OPML\n
      \n

      \nOPML (Outline Processor Markup Language) is an XML format for outlines (defined as \"a tree, where each node contains a set of named attributes with string values\"). Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feeds between web feed aggregators.
      \nFrom Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/OPML\n

      \n\n

      \nThat's it. You now have a list of all your feeds we are still faced with the problem of reading/deleting items in one place and having them synchronized everywhere else ? The answer is actually quite obvious.\n

      \n

      imap - Internet Message Access Protocol

      \n

      \nFrom Wikipedia, the free encyclopedia
      \nhttps://en.wikipedia.org/wiki/Internet_Message_Access_Protocol
      \nInternet message access protocol (IMAP) is one of the two most prevalent Internet standard protocols for e-mail retrieval, the other being the Post Office Protocol (POP). Virtually all modern e-mail clients and mail servers support both protocols as a means of transferring e-mail messages from a server.      \n

      \n

      \nThe great news is that there are imap clients everywhere. Microsoft Outlook supports it. Thunderbird, Evolution, Kmail, Claws-Mail all support it. It's supported on Android, the iPhone, and on Windows Mobile. There are a multitude of web clients. The only problem now was to find a way to get the RSS feeds over to a imap message format. A quick duckduckgo search later lead me to ....\n

      \n

      Feed2Imap

      \n

      https://home.gna.org/feed2imap/
      \nFeed2Imap is an RSS/Atom feed aggregator. After Downloading feeds (over HTTP or HTTPS), it uploads them to a specified folder of an IMAP mail server or copies them to a local maildir. The user can then access the feeds using Mutt, Evolution, Mozilla Thunderbird or even a webmail.\n

      \n

      \nIt's in all the major repositories and I had it up and running in under ten minutes. It keeps it's settings in a hidden file .feed2imaprc in your home directory. The configuration is simple, four lines per feed.\n

      \n
      \nfeeds:\n - name: kenfallon.com\n   url: https://kenfallon.com/?feed=rss2\n   target: imap://RSSNewsAccount%40example.com:PasswordForRSSNewsAccount@imap.example.com/INBOX.Feeds.Tech_Blogs\n   include-images: true\n...\n
      \n

      \nThe name filed is what will be the feed name and url is the link to the rss feed. The target is the path on the imap account you want to put it to. I used a throw away email account on my own domain with some restrictions on the size so that if I forget to check it won't affect the rest of my mailboxes.
      \nThe line it's broken into several parts, first is imap:// followed by the imap account user name and password. If your login contains an @ character, replace it with %40. Next is the @ sign followed by your server hostname and then the path. I chose INBOX.Feeds and then a subfolder for every group I had in Google Reader. The only other option I set was to include the images.\n

      \n

      opml2feed

      \n

      \nI have quite a few feeds now and I did not want to be typing them in by hand. So I wrote a small perl script to convert the opml file into a .feed2imaprc format and it will hopefully get you most of the way. The code is available on https://gitorious.org/opml2feed ( thanks to Klaatu over at https://www.gnuworldorder.info/ where he covered using Git in the March 31, 2012: Episode 7x13.)\n

      \n

      \nNow setup the imap account on your mail client(s) and once you are happy run feed2imap and you should see the items beginning to appear. I set it to run every two hours at 14 minutes past the hour by adding the following line to my cron tab.\n

      \nTrisquel GNU/Linux is a 100% free operating system. It comes with a complete selection of programs that can be easily extended using a graphical installer. There are several editions available, including the \"mini\" edition for netbooks and old computers and the network based installer for custom and server installations.\n      \n

      \nThe du command provides a summary of disk usage for files and directories. The default behavior is to show the number of blocks used by the contents of a directory or directories the command is run on. Usage is calculated recursively for directories. When du encounters a directory it will recurse into subdirectories and show the disk utilization of the files and directories under that directory and then present a total for the topmost directory. This cascades down through each subdirectory where the subdirectory becomes the parent and each child directory is summarized and the parent then totalled.\n

      \nIn todays show, Ken tells of his struggle to get silent PC to work with his spare 17\" monitor. His attempts to get a \"VIA EPIA M9000 Mini ITX Motherboard\" failed miserably and so he has turned to a HP Compaq t5000 thin client. As can be seen in this post here and discussed here.\n

      \n

      \n\n

      \n

      \nThe OS installs fine from USB but you run into grub issues on reboot that require you to boot from USB disk to rectify and that runs into problems as the boot order get's confusing. To get around this I decided to install Debian via PXE boot or more commonly \"Pixie\" boot. A full description can be found on the debian wiki. Basically it involves setting up a DHCP server, a TFTP server and downloading a boot image.\n

      \n

      \nOnce you have everything configured is a standard Debian net install. The only gotya is entering the MAC address of your Client and making sure you know what is happening on your network with regard to DHCP. I set the internal sd drive as the boot partition, created a 500Mb swap on my 4G external disk and put the root as the rest. I set both the boot and the root partition to ext2 as I didn't want the added strain of journaling on the sd media.\n

      \n

      \nI ran into the Grub 2 ERROR 17 issue which meant that I had to do some reading on Grub2 and we're back to the bad old days of lilo where you need run commands or your config changes are ignored. Anyway another Pixie boot, this time into recovery mode long enough to type update-grub. A quick reboot and we're into a standard Debian base install.\n

      \n

      \nI took the steps to installing Debian multimedia by adding the magic deb https://www.debian-multimedia.org squeeze main non-free to my /etc/apt/sources.list and then doing\n

      \naptitude install debian-multimedia-keyring\n
      \nto get the keyring in order. After that it was a aptitude update and a aptitude safe-upgrade and that was it. I was free to install anything I wanted.\n

      Introducing Andy Piper on MQTT: MQ Telemetry Transport

      \n\n

      MQTT is a machine-to-machine (M2M)/\"Internet of Things\" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers

      \n

      \nLibre.fm
      \nFrom Wikipedia, the free encyclopedia\n

      \n\n

      \nLibre.fm is a music community website that aims to provide a Free Software replacement for last.fm. The website was founded in 2009 by Matt Lee. It is under active development.\n

      \n

      \nLibre.fm can optionally store a user's listening habits using information sent to the website's server from the user's audio player via scrobbling. In order to enable support for Libre.fm on existing audio players, the website implements the Last.fm Audioscrobbler API. In addition to collecting user uploaded listening data, the site offers streaming music using the Ogg container, from the sites Jamendo or The Internet Archive, via an HTML5 audio player, run directly in the user's browser.\n

      \n

      \nBy utilising the records of users' listening habits, the website aims to be able to recommend music to users by analysing their musical taste. However, this feature isn't fully developed yet. The site currently only offers basic suggestions if content a user has \"Loved\" (favorited), contains shared tags with content a user has not favorited yet. Registered users who have favorited tracks, will have that content appear in streaming web playlists, called \"Radio Stations\". It is not currently possible to build custom playlists.\n

      \n

      \nA goal of the project is to encourage artists to release tracks under a free license, and allow users to download or purchase these tracks. Only artists releasing music under free content licenses are promoted by the site. The website will also allow users to communicate among themselves, create groups of common interests and share information on musical events.\n

      \n

      \nThe main reasoning behind the foundation of Libre.fm was to provide a service similar to last.fm that respects the privacy of its users and their information. As such, Libre.fm does not log users' IP addresses, allows users to decide if their listening habits are to be made public or not, and does not claim ownership on users' data.\n

      \n

      \nLibre.fm is powered by the free software package GNU FM, created for the project.\n

      The tail command is used to print out the last 10 lines of a file to standard out. This command is a staple in a system administrator’s tool kit and especially handy when monitoring log files. The basic syntax is:

      \n

      tail some_file

      \n

      Which will output the last 10 lines of the file. You can alter the number of lines with the -n, or –lines=, flag:

      \n

      tail -n20 some_file
      \ntail –lines=20 some_file

      \n

      In some versions of tail you can get away with specifying the number of lines from the end with just a “-” and number:

      \n

      tail -30 some_file

      \n

      Instead of working backwards with the -n command you can specify a “+” and some number to start from that number and list the contents to the end:

      \n

      tail -n+30 some_file

      \n

      This will display the contents of some_file from line 30 to the end of the file.\n

      Ohio LinuxFest 2012 Registration is Open for Business

      \n

      \nA message from Kevin O'Brien
      \nWe are opening up Registration for the 2012 Ohio LinuxFest event, and we'd appreciate it if you could pass along this message through whichever social media you prefer. The Registration page is at https://ohiolinux.org/register\n

      AccessibleComputingFoundation fundraiser

      \n

      \nWe would like to announce the first fundraiser for the Accessible Computing Foundation!. It will be held on August 25 from 12pm EST until 12am EST August 26. This event will be streamed at The New Radiofor the entire event. It's going to be held over at Linux Basix, using their Mumble server. To find out the information for the Mumble server, please visit the Linuxbasixsite . We'll be able to have up to 30 people in the room at once, so come and join us in talking about accessibility and Free software.
      \n
      \nSo far, joining the event we will be having Jono Bacon from Ubuntu, and Zack the Debian project leader. If you'd like to speak with either of them, please come and join us on August 25. The goal for this fundraiser is to have 1000 people become members of the ACF at $2 a month. We have 3 other levels of membership options if anyone is interested. This would be a great help to the foundation and really get us off of the ground to start bridging the gap between accessibility and technology.
      \n
      \nThe reason we're focusing on the $2/month level is because it's only 50 cents a week and we think this is a goal most people could meet, even if living on a fixed income like so many people with disabilities. Since monthly membership is so low, we are really depending on MANY people to become members to make this difference. Granted $2 a month isn't much, but if we can get a large number of people thinking this way, it will add up quickly and help out the Accessible Computing Foundation in a great way. So please, join us on August 25 and help bring Accessible Freedom to people around the world!\n

      Hello world. Welcome to the Full Circle Podcast on Hacker Public Radio. This episode consists of an interview with journalist and author Becky Hogge.

      \n\n

      Her book, Barefoot into Cyberspace: Adventures in Search of Techno Utopia came out last year around the time of the extradition case surrounding Wikileaks founder Julian Assange. The book explores modern technology and society through activism and journalism, covering the hacker counter-culture, from Stallman and Lessig, the Chaos Club to WikiLeaks Julian Assange and Rop Gonggrijp.

      “I think most of what were fighting still today in the world is incompetence. Most of what we’re fighting is stupidity, and maybe a little bit of opportunism. There is also the ominous, control-seeking large corporate interests.”

      \n\n

      “We come in peace. We’re not called Chaos Computer Club because we cause chaos. If anything, a lot of our collective work has actually prevented chaos by pointing out that maybe we should lay some decent virtual foundations before we build any more virtual skyscrapers.”

      Be Very Afraid! In this mini-interview Simon gives a quick introduction to the Communications Data Bill, recently introduced to the UK Parliament, which proposes to establish a nation-wide database of all citizens' text and email communications, and explains the problems with the proposals, notably the lack of judicial oversight and the massive potential for mission creep.

      \n\n

      Transcript:

      \n\n

      doubi: We're here at OggCamp 2012 at John Moores University in Liverpool and I'm here with Simon Phipps who's going to be giving a talk tomorrow on behalf of the Open Rights Group. Simon, what will your talk be about?

      \n\n

      Simon Phipps: I'm going to be talking about the Communications Data Bill, which is a piece of legislation that's just about to go through Parliament, and has very worrying consequences for people's civil liberties on the internet.

      \n\n

      doubi: Right, \"Communications Data\" maybe doesn't sound like it's to do with people's civil liberties, so what's it all about?

      \n\n

      Simon: Well, this is a Bill that solves a problem for the security services in the UK, in particular the secret service that we have over here, and the police forces. They're very worried that they can't see what's going on inside your email, and inside your text messaging, and inside your other online communications.

      \n\n

      They have for a long time been trying to get a succession of governments to put into law rules that allow them to snoop on all of your communications. They tried to do it under [the previous Labour Party government], and it didn't quite work out because there was an outcry in civil society about it, and it's now happening under the Tories and Liberal Democrats. So this is not a partisan issue at all. This is an activity that is arising out of the Cheltenham data centre that is used by the intelligence services and arising out of the police forces, who are all very worried that they can't read your email.

      \n\n

      doubi: Now, I've heard a little bit about this and I've heard it pitched in terms of, \"This is the security services just trying to keep up with changing technology.\" What do you say to that, because people obviously people are using different forms of communication now; is there anything legitimate in the security services needing to \"keep up\" with that?

      \n\n

      Simon: I think it's legitimate for them to need to \"keep up\" but that is not a good excuse for them to do what they're doing here, because what they're doing is creating a right to ask every internet service provider to keep, for twelve months, all of your traffic on the internet, so they can analyse it off-line. That gives them plenty of time to crack SSH, to crack SSL keys, to crack any encryption that's going on.

      \n\n

      The big problem is that this right is being created fresh, it's being created without any right for you to know that it's happening, it's being created without any judicial oversight, so that the police can just decide to ask for your material to be created. It's also being created in such a way that should the police choose to they could create a central database of all this information that could then be casually searched.

      \n\n

      By \"casually searched\", I mean it could be searched, for example, by organisations enforcing family law disputes, organisations enforcing defaults on mortgage payments, organisations who are looking into whether you have renewed the MOT [annual road-worthiness test] on your car. All of those would be the sort of excuses to go dipping in on a fishing expedition on your personal data.

      \n\n

      So what's being proposed is not just keeping up to date with technology, it's going way, way, way beyond any scope for keeping up, and it's creating for the first time a database of citizen communications that can then in the future be fished-into arbitrarily, without notification, without recourse and without judicial oversight.

      \n\n

      doubi: It might sound to people like some of the examples you gave about the misuse of such a database are hypothetical or facetious, but already if people were to go to the Open Rights Group website, openrightsgroup.org there are on the wiki there are documented examples of how local councils, both individuals and in an official capacity, are already abusing some of these databases that are intended for much more serious purposes and are ostensibly there to save us from real threats [NB: This is inaccurate; please see footnote].

      \n\n

      Simon: When these things get started, they're always packed in guarantees that nobody will do anything bad with your data. The CDB is no different: all of the padding around it says, \"Trust us to create this database of communications, because look at all these protections we're putting around it to prevent abuse.\" Now what we know is that once you've created a resource, mission creep in the future will change the way that it's used.

      \n\n

      Take for example the congestion charge cameras in London. All around London now there are number-plate [license-plate] recognition cameras that were put there only to collect congestion charges. But as time has gone by, people have found other, extremely legitimate uses for them: to prevent terrorism, to enforce laws. And now they are part of a network that the police can routinely use to identify the location of any vehicle in central London. That wasn't what the cameras were put there for, and when they were set up we were told that wasn't going to happen.

      \n\n

      I look at the CDB and I believe it's exactly the same thing. The thing that's wrong with the Communications Data Bill is not the uses to which the authorities will put the data, it is creating the repository of data in the first place.

      \n\n

      doubi: Absolutely. And I think together with the lack of judicial oversight which you already mentioned, those are the really scary aspects about this. What can people do at this stage?

      \n\n

      Simon: Well, at the lowest level what people can do it join the Open Rights Group. The Open Rights Group is an organisation which is funded largely from the membership fees of its members. You can visit openrightsgroup.org and sign up, set up a standing order to pay is little as £5 a month, that will help to pay for professional researchers to understand all these highly complex laws, and then go and engage on your behalf, to make sure that the bad things don't happen.

      \n\n

      If you're more motivated than that, than just joining, you could get involved with a local chapter of the Open Rights Group. There are local chapters all over the UK, where you can meet with other like-minded people and take local action: ttalking with MPs, talking with local radio stations, talking with local newspapers, and making sure that the digital rights agenda of the individal citizen has as loud a voice as the media lobby is able to bring to corporate concerns.

      \n\n

      doubi: Sounds great. Simon, thank you very much; do you want to give your vital statistics, where to find you on the web?

      \n\n

      Simon: I do all sorts of things of the web. They are all locatable from my website webmink.com.

      \n\n

      doubi: Thank you very much, looking forward to your presentation tomorrow, and enjoy OggCamp!

      \n\n

      Simon: Thank you very much.

      \n\n

      \n

      NB: I was quite wrong about the ORG wiki. There isn't a page about concerted abuses of centralised data repositories as such; what there is the UK Privacy Debacles page, which lists (worryingly numerous) examples of companies and public bodies accidentally losing or releasing data. There's only one example of malicious abuse by an individual.

      \n\n

      However, these examples of organisational incompetence to deal with data in themselves give an independent reason why the data store proposed by the CDB is a bad idea. Secondly, the examples of misuse of investigative resources and powers has been well documented elsewhere ([1], [2]).

      \nI was leaving my hotel room after the end of OggCamp, thinking to myself I had enough interviews recorded and something made me go back and get my recorders. I'm glad I did as I bagged some fantastic interviews. \n

      \n

      \nThe first one was with Rebecca Newborough web mistress of the Lincoln LUG https://lincoln.lug.org.uk/ on how to start a LUG. The first step is to visit the UK Linux User Groups site at https://lug.org.uk/\n

      \n

      \nWe all went to the Leaf venue for food and conversation https://thisisleaf.co.uk/#/on-bold-street/, while there I interviewed a few gentlemen starting with Kris Findlay about changes at his LUG and his work at Krisilis IT Solutions www.krisilis.com

      \n\nThe Software Society https://www.thesoftwaresociety.org.uk\n

      \n

      \nThen we had a chat with Ian Closs over from Ireland. We discussed the local FLOSS scene, Mark Shuttleworth https://en.wikipedia.org/wiki/Mark_Shuttleworth who will be attending SkyCon https://skycon.skynet.ie/2012/ and Archeology.\n

      \n

      \nTo round it all off a long round up with Fabian A. Scherschel https://sixgun.org/fabsh/ who true to his word gave me an interview for HPR. Of course he is still on record to submit a show to HPR himself.\n

      \n

      \nYou might think that's the end of OggCamp but I still have shows from last year to post :)\n

The task area usually takes up three quarters of the top window. This display is not the only informative view that top has.

      At the conference FSCONS I have a talk with both Henrik (who has no previous experience of FSCONS) and Jonas (who organise the conference). Two very different perspectives and a few completing comments from me.

      \n\n

      Henrik

      \n\n

      Henrik mentioned the two All In IT Radio episodes \"Assembly Overclocked\" where he told us of his experiences from the demo party Assembly and \"Should Cars Get Smarter?\" where we talk about Qt, In Vehicle Infotainment and such. The later show was featured as episode 0854 on Syndicated Thursday on Hacker Public Radio. We also referenced Jeremiah Foster, Johan Thelin and Mathias Klang

      \n\n

      Jonas

      \n\n

      When Jonas mentions \"Henrik\", he does not mean the Henrik of All In IT Radio fame, but rather Henrik Sandklef who sits on the board of \"Föreningen fri kultur och programvara\".

      MariaDB

      \n

      From Wikipedia, the free encyclopedia\n

      \n

      \nMariaDB is a community-developed branch of the MySQL database, the impetus being the community maintenance of its free status under the GNU GPL, as opposed to any uncertainty of MySQL license status under its current ownership by Oracle. The contributors are required to share their copyright with Monty Program AB.\n

      \n

      \n\nThe intent also being to maintain high fidelity with MySQL, ensuring a \"drop-in\" replacement capability with library binary equivalency and exacting matching with MySQL APIs and commands. It includes the XtraDB storage engine as a replacement for InnoDB,[4] as well as a new storage engine, Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.\n

      \n

      \n\nIts lead developer is Michael \"Monty\" Widenius, the founder of MySQL and Monty Program AB. He had previously sold his company, MySQL AB, to Sun Microsystems for 1 billion USD.

      Useful Vim Plugins

      \n

      I started learning vi a long time ago when I first encountered Unix systems. In those days you could usually count on a system having vi (or at a pinch, when the system would only boot into single user mode, ed). Learning Emacs didn't seem like a good choice since it wasn't usually available on the systems I was administering.

      \n

      I don't remember when I changed to Vim, but for many years I have used it (actually gVim) as an IDE (Integrated Development Environment), particularly for writing Bash and Perl scripts.

      \n

      In these notes I have listed some of the plugins I use to enhance Vim and gVim's functionality. If you have never made enhancements to this editor, here's a site with a very good tutorial on how to install plugins https://www.installationwiki.com/Installing_Vim_Scripts.

      \n
      \n

      NERDTree

      \n \n

      This plugin provides a file browser within Vim/gVim. A particular directory is opened by typing :NERDTree somedir. A tree is displayed in a window which can be scrolled and traversed to find files to edit.

      \n

      \"\"

      \n

      In case you're interested, the colour theme I use in gVim is \"Murphy\".

      \n

      Type :h NERD_tree for the large and comprehensive help file.

      \n

      I prefer to use NERDTree in gVim and not in Vim. To achieve this I have the following in my ~/.vimrc

      \n  \" NERDTree settings (only in GUI mode)\n  if has(\"gui_running\")\n      let NERDTreeRoot = '~'\n      let NERDTreeIgnore = ['\\~$', '\\.swp$']\n      let NERDTreeShowHidden = 1\n      let NERDTreeShowBookmarks = 1\n      let NERDTreeChDirMode = 2\n  else\n      let loaded_nerd_tree = 1\n  endif\n
      \n

      Bash-support

      \n \n

      This one provides a Bash scripting IDE for Vim and gVim. I find it most usable in gVim where it offers a comprehensive set of menus which you can see in the example.

      \n

      From the Help text:

      \n  It is written to considerably speed up writing code in a consistent style.\n  This is done by inserting complete statements, comments, idioms, and code\n  snippets. Syntax checking, running a script, starting a debugger can be done\n  with a keystroke. There are many additional hints and options which can\n  improve speed and comfort when writing shell scripts.\n

      \"\"

      \n

      The plugin can be used from the menu or by typing short-cut sequences such as \\ct which inserts the current date and time at the cursor position. It's an amazingly detailed package that's well worth dedicating the time to learn if you often write Bash scripts.

      \n
      \n

      Perl-support

      \n \n

      This plugin provides a Perl scripting IDE for Vim and gVim. As with the Bash plugin from the same author I find it most useful from gVim where the menus can be used to perform a wide range of actions.

      \n

      Again, you can use it to insert statements, boilerplate text and comments, in a similar way to the Bash plugin. You can also get regular expression help, check, run and debug the script

      \n

      Two of the functions I find particularly useful are perltidy and perlcritic. Perltidy will reformat your Perl script, and Perlcritic will critique it according to the rules based on Damian Conway's book Perl Best Practices.

      \n

      \"\"

      \n

      Note the lower window showing the various problems detected by perlcritic.

      \n

      If you are a C or C++ programmer Fritz Mehner also provides a plugin for these languages here.

      \n
      \n

      manpageview

      \n \n

      This is a man page viewer for use within Vim. Use :Man topic or press K on a keyword. Can view perl, php and python help.

      \n

      This is a great way to view man pages, with the ability to search and cut and paste the contents.

      \n
      \n

      Surround

      \n \n

      The plugin provides mappings to easily delete, change and add \"surroundings\" such as quotes, braces and parentheses.

      \n

      The following extract from the Help text should make this clearer:

      \n  Consider the following examples.  An asterisk (*) is used to denote the cursor\n  position.\n  \n    Old text                  Command     New text\n    \"Hello *world!\"           ds\"         Hello world!\n    [123+4*56]/2              cs])        (123+456)/2\n    \"Look ma, I'm *HTML!\"     cs\"<q>      <q>Look ma, I'm HTML!</q>\n    if *x>3 {                 ysW(        if ( x>3 ) {\n    my $str = *whee!;         vlllls'     my $str = 'whee!';\n
      \n

      Fugitive

      \n \n

      A very powerful interface to git.

      \n

      \"\"

      \n

      The image shows the result of the :Gstatus command which is equivalent to typing git status on the command line.

      \n
      \n

      Taglist

      \n \n

      This plugin provides source code browsing by listing tags (functions, classes, structures, variables, etc.). The list is in a window in Vim or in a menu in gVim.

      \n

      The plugin makes us of the Exuberant Ctags utility to index tags in a source file. I believe that most Linux distributions ship with this utility, but if not it seems to be easily available in repositories.

      \n

      \"\"

      \n

      The image shows gVim with the tag list in a window. I find the menu in gVim more useful myself.

      Supertab

      \n \n

      Provides insert completion functionality using the Tab key.

      \n

      \"\"

      \n

      The example shows a Perl script where the choice being made from the list offered by Supertab is uptodate. Note also that manpageview is being used to view the manpage for the CPAN module.

      \n

      It has taken me a while to learn not to use the Tab key to enter TAB characters but to use CTRL-Tab instead. However, I have decided that the advantages of redefining the Tab key in this way outweigh the disadvantages. You might not agree!

      Recovery of an (en)crypted home directory in a 'buntu based system

      \n

      by 5150

      \n


      \n

      \n

      This is going to be the archetypal “How I Did It” episode because if fulfills the criterion of dealing with an issue most listeners will most likely never have to resolve, but might be invaluable to those few who some day encounter the same problem, how to recover an encrypted home folder on an Ubuntu system.

      \n

      I enabled home folder encryption on installation of a Linux Mint 8 system some years back and it never gave me trouble until the day that it did. Suddenly, my login would be accepted, but then I would come right back to GDM. Finally I dropped into a text console to try to recover the contents of my home folder, and instead found two files, Access-Your-Private-Data.desktop and README.txt . README.txt explained that I had arrived in my current predicament because my user login and password for some reason were no longer decrypting my home folder (Ubuntu home folder encryption is tied to your login, no additional password is required). Honestly, until I lost access to my files, I 'd forgotten that I'd opted for encryption. I found two\narticles that described similar methods of recovery. I'd tried that following their instructions and failed, probably because I was mixing and matching what seemed to be the easiest steps to implement from the two articles. When I took another look at the material weeks later, I discovered I missed a link in the comments that led me to an improved method added at Ubuntu 11.04 that saves several steps:\nhttps://blog.dustinkirkland.com/2011/04/introducing-ecryptfs-recover-private.html

      \n
        \n

      1. Boot to an Ubuntu distribution CD (11.04 or later)

        \n

      2. Create a mount point and mount the hard drive. Of course, if you configured you drive(s) with multiple data partitions (root, /home,\netc) you would have to mount each separately to recover all the contents of your drive, but you only have to worry about decrypting your home directory. If you use LVM, and your home directory spans several physical drives or logical partitions, I suspect things could get interesting.

        \n
          \n

        1. $sudo mkdir /media/myhd

          \n
            \n

          1. /media is owned by root, so modifying it requires elevation

            \n
          \n

        2. You need to confirm how your hardrive is registered with the OS. I just ran Disk Utility and confirmed that my hard drive was parked\nat /dev/sda, that meant that my single data partition would be at /dev/sda1

          \n

        3. $sudo mount /dev/sda1 /media/myhd

          \n

        4. Do a list on /media/myhd to confirm the drive is mounted

          \n
            \n

          1. $ls /media/myhd

            \n
          \n

        5. The new recovery command eliminates the need to re-create your old user

          \n
            \n

          1. $sudo ecryptfs-recover-private (yes, ecrypt not encrypt)

            \n

          2. You will have to wait a few minutes while the OS searches your hard drive for encrypted folders

            \n
              \n

            1. When a folder is found, you will see

              \n

              INFO:\nFound [/media/myhd/home/.ecryptfs/username/.Private].

              \n

              Try to recover this directory? [Y/n]

              \n
                \n

              • Respond “Y”

                \n
              \n

            2. You will be prompted for you old password

              \n

            3. You should see a message saying your data was mounted read only at

              \n

              /tmp/ecryptfs.{SomeStringOfCharacters}

              \n
                \n

              • I missed the mount point at first, I was look for my files in /media/myhd/home/myusername

                \n
              \n
            \n
          \n

        6. If you try to list the files in /tmp/ecryptfs.{SomeStringOfCharacters}, you will get a “Permission Denied” error. This because your old user owns these files, not your distribution CD login

          \n
            \n

          1. [You will probably want to copy “/tmp/ecryptfs.{SomeStringOfCharacters}” into your terminal buffer as you will need to reference it in commands. You can select if with your mouse in the “Success” message and copy it with <Ctrl><Alt>c, paste it later with <Ctrl><Alt>v

            \n

          2. I tried to take ownership of /tmp/ecryptfs.{SomeStringOfCharacters}, I should have thought that would have worked.

            \n
              \n

            1. From my command prompt, I can see my user name is “ubuntu”

              \n

            2. $ sudo chown -R ubuntu /tmp/ecryptfs.{SomeStringOfCharacters}

              \n
                \n

              • -R takes ownership of subdirectories recursively

                \n

              • It's a good time to get a cup of coffee

                \n
              \n
            \n
          \n

        7. Next, we need to copy the files in our home directory to another location, I used an external USB drive (it was automounted under /media when I plugged it in). If you had space on the original hard drive, I suppose you could create a new user and copy the files to the new home folder. I decided to take the opportunity to upgrade my distro. Some of the recovered files will wind up on my server and some on my newer laptop.

          \n
            \n

          1. One could run Ubuntu's default file manager as root by issuing “sudo nautilus &” from the command line (the “&” sends the\nprocess to the background so you can get your terminal prompt back)

            \n
              \n

            1. Before copying, be sure to enable “View Hidden Files” so the configuration files and directories in you home directory will be recovered as well. As I said, there are select configuration files and scripts in /etc I will want to grab as well.

              \n
            \n

          2. I had trouble with Nautilus stopping on a file it couldn't copy, so I used cp from the terminal so the process wouldn't stop every\ntime it needed additional input.

            \n
              \n

            1. $ cp -Rv /tmp/ecryptfs.{SomeStringOfCharacters} /media/USBDrive/Recovered

              \n
                \n

              • Of course the destination will depend on what you've named your USB drive and what folder (if any) you created to hold your recovered files

                \n

              • -Rv copies subdirectories recursively and verbosely, otherwise the drive activity light may be your only indication of progress. The cp command automatically copies hidden files as well.

                \n

              • Because of the file ownership difficulties, I could only copy the decrypted home folder in its entirety, \n

                \n
              \n
            \n

          3. I still had trouble with access do to to ownership once I detached the external drive and remounted it on my Fedora laptop, but I\ntook care of that with:

            \n
              \n

            1. $ su -c 'chown -R mylogin/media/USBDrive/Recovered'

              \n
            \n

      It took 14 months longer than intended to get this episode done! To make up \nfor it, I've unintentionally ended up with enough time of me talking to almost\nmake up a minimal-useful-sized episode every month while everyone's been \nwaiting.

      \n

      Today's episode of \"Thoughtkindness\" consists of:

      \n
        \n
      • Me begging for forgiveness for disappearing for a year.
        • \n
      • An update on \"bunnies\", my linux laptop from Ohava Computers
        • \n
      • Over an hour of my attempt to collect and explain why we need \nto make media on the internet more \"freetarded\"
        • \n
      \n

      After revealing what ticked me off and made me start on this episode, I \nlaunch into a short technical and historical talk about the handful of audio \nand video files that matter on the web today.

      \n

      (Opus, Ogg Vorbis, WebM, MP3, Flash Video, MP4, and a few others).

      \n

      Following this, I explain why I think the legally-free media formats are\nso important, and much more useful than most people seem to recognize, why\nI think we need to be paying more attention to audio than video, and what\nneeds to happen to make legally-free media ubiquitous.

      \n

      I conclude by once again begging for attention and foolishly publically\nannouncing that I want to try to develop some software and invite everyone\nto pester me for it as well as for future audio shows. Maybe I won't be \nallowed to procrastinate for another year before producing more this time.

      This is another one of my How I Did It\nPodcasts (or How I Done It if you rather) where my goal is to pass\nalong the things I learn as a common Linux user administering my home\ncomputers and network, and engaging in the types of software\ntinkering that appeals to our sort of enthusiast.

      \n


      \n

      \n

      I'd been thinking for a while about\nreplacing the small computer on my dinner table. I had been using an\nold HP TC1000, one of the original active stylus Windows tablets, of\ncourse now upgraded to Linux. With the snap in keyboard, it had a\nform factor similar to a netbook, with the advantage that all the\nvulnerable components were behind the LCD, up off the table and away\nfrom spills. It had served my purpose of staying connected to IRC\nduring mealtimes, and occasional streaming of live casts, but I\nwanted more. I wanted to be able to join into Mumble while preparing\nmeals, I wanted to be able to load any website I wanted without\nlockups, and I wanted to stream video content and watch DVDs.

      \n


      \n

      \n

      I was concerned that putting a laptop\non the table was an invitation to have any spilled beverage sucked\nright into the air intakes, and I never even considered a desktop\nsystem in the dining room until I saw a refurbished Dell Inspiron 745\non GearXS.com (I wouldn't normally plug a specific vendor, but now\nGearXS is putting Ubuntu on all it's used corporate castoff systems).\nThis Dell had the form factor that is ubiquitous in point-of-sale, a\nvertical skeleton frame with a micro system case on one side and a\n17” LCD on the other, placing all the electronics several inches\nabove the surface on which it is placed. I even found a turntable\nintended for small TVs that lets me smoothly rotate the monitor to\neither at my place on the table or back towards the kitchen where I\nam cooking. I already had a sealed membrane keyboard with an\nintegrated pointer and wireless-N USB dongle to complete the package.\nShipped, my “new” dual core 2.8Ghz Pentium D system with 80Gb\nhard drive and Intel graphics was under $150. [The turntable was $20\nand an upgrade from 1Gb to 4Gb of used DDR2 was $30, but both were\nworth it.] Since the box shipped with Ubuntu, I thought installing\nthe distro of my choice would be of no consequence, and that is where\nmy tale begins.

      \n


      \n

      \n

      I'm going to start my story towards the\nend, as it is the most important part. After the installation of four\nLinux distros in as many days (counting the Ubuntu 10.04 LTS the box\nshipped with, a partial installation of SolusOS 2r5, Fuduntu and\nfinally Lubuntu 12.04), I discovered I couldn't boot due to Grub\ncorruption (machine POSTed, but where I should have seen Grub, I got\na blank screen with a cursor in the upper left corner). \n

      \n


      \n

      \n

      A. I thought I would do a total disk\nwipe and start over, but DBAN from the UBCD for Windows said it\nwasn't able to write to the drive (never seen that before) \n

      \n

      B. Started downloading the latest\nRescaTux ISO. Meanwhile, I found an article that told me I could\nrepair Grub with a Ubuntu CD\nhttps://ubuntunigeria.wordpress.com/2010/09/02/how-to-restore-grub2-using-an-ubuntu-live-cd-or-thumb-drive/\n, so I tried booting from the Lubuntu 12.04 CD (using the boot device\nselector built into the hardware). Same black screen, preceded by a\nmessage that the boot device I had selected was not present. Same\nthing with the Fuduntu DVD that had worked the day before. With the\nexception of UBCD, I couldn't get a live CD to boot. \n

      \n

      C. Now having downloaded the RescaTux\nISO, and suspecting a problem with the optical drive, I used\nUnetbootin to make a RescaTux bootable thumb drive. RescaTux \n

      \n

      (\nhttps://download2.berlios.de/rescatux/rescatux_cdrom_usb_hybrid_i386_486-amd64_0.30b7_sg2d.iso\n) has a pre-boot menu that let's you choose between 32 and 64 bit\nimages, but that was as far as I got, nothing happened when I made my\nselection. \n

      \n

      D. At this point, I am suspecting a\nhardware failure that just happened to coincide with my last install.\nThis is a Ultra Small Form Factor Dell, the kind you see as point of\nsale or hospital systems, so there weren't many components I could\nswap out. I didn't have any DDR2 laying around, but I did test each\nof the two sticks the system came with separately with the same\nresults. I then reasoned a Grub error should go away if disabled the\nhard drive, so I physically disconnected the drive and disabled the\nSATA connector in the BIOS. I still couldn't boot to a live CD.\nDeciding there was a reason his machine was on the secondary market,\nI hooked everything back up and reset the BIOS settings to the\ndefaults, still no luck. \n

      \n

      E. As a Hail Mary the next day, I\nburned the RescaTux ISO to a CD and hooked up and external USB\noptical drive. This time, I booted to the Live CD, did the two step\ngrub repair, and when I unplugged the external drive, I was able to\nboot right into my Lubuntu install. Now booting to Live CDs from the\noriginal optical drive and from the thumb drive worked. RescaTux FTW.\n

      \n


      \n

      \n

      Now a little bit on how I got in this\nmess. As I said, the Dell shipped with 10.04, but I wanted something\nless pedestrian than Ubuntu (ironic I wound up there anyway). I tried\nHybride, but once again, like my trial on the P4 I mentioned on\nLinuxBasix, the Live CD booted, but the icons never appeared on the\ndesktop (I think it's a memory thing, the Dell only shipped with a\ngig, shared with the integrated video). After Hybride, I really\nwanted to be one of the cool kids and run SolusOS, but the install\nhung twice transferring boot/initrd.img-3.3.6-solusos. I casted\naround for a 64bit ISO I had on hand, and remembered I'd really\nwanted to give Fuduntu a try. Fuduntu is a rolling release fork of\nFedora, with a Gnome 2 desktop, except that the bottom bar is\nreplaced with a Mac style dock, replete with bouncy icons (cute at\nfirst,but I could tell right away they would get on my nerves).\nHowever, I found I liked the distro, despite the fact I found the\ndefault software choices a little light for a 900Mb download (Google\nOffice, Chromium, no Firefox, no Gimp). Worst of all, no Mumble in\nthe repos at all (really Fuduntu guys? While trying to install\nMumble, do you know how many reviews I found that can be summed up as\n"Fuduntu is great, but why is there no Mumble?").\nUnfortunately, I put Mumble on the back burner while I installed and\nconfigured my default set of comfort apps from the repos (Firefox,\nXChat, Gimp, VLC, LibreOffice, etc). [BTW, with the anticipated\narrival of a 2.4ghz headset, I hope to be able to use the new machine\nto join the LUG/podcast while preparing and dare I say eating\ndinner.] \n

      \n


      \n

      \n

      I visited the Mumble installation page\non SourceForge, and found they no longer linked to .deb files and\nfedora .rpms, as they assume you can install from your repositories.\nThinking someone must have found an easy solution, I hit Google. The\nbest answer I found was a page on the Fuduntu forums\n(https://www.fuduntu.org/forum/viewtopic.php?f=21&t=2237 ), that\nsuggested downloading the Mumble and a dozen prerequisite library\n.rpm's from a third party site called rpm.pbone.net. I visited\npbone.net, and found when I looked up each library, I got a dozen\ndifferent links to versions of the file. Then I saw a link that\nseemed to offer the promise of simplifying my task, if I subscribed\nto pbone.net, I could add their whole catalog as a repo. While\nresearching the legitimacy of pbone.net, I found them mentioned in\nthe same sentence as RPMFusion as an alternate repository for Fedora.\nI decided to install the RPMFusion repos as well, thinking I might\nfind some of the needed libraries in there. I registered with pbone,\nand discovered I would only have access to their repository for 14\ndays free, after which it would cost $3 a month (after all, hosting\nsuch a service must cost money). I figured the free trial would at\nleast get Mumble installed, and went through the set up. Among the\nquestions I had to answer were which Fedora version I was running (I\npicked 17, since Fuduntu is rolling) and 32 or 64 bit. pbone.net\ngenerated a custom .repo file to place in my /etc/yum.repos.d\ndirectory. At this time, I'd already set up RPMFusion. \n

      \n


      \n

      \n

      The fun started when I ran 'yum\nupdate'. I got "Error: Cannot find a valid baseurl for repo:\nrpmfusion-free". It turns out (\nhttps://optics.csufresno.edu/~kriehn/fedora/fedora_files/f10/howto/repositories.html\n) the location of the RPMFusion servers are usually commented out in\nthe .repo files, Fedora must know where they are, but I guess Fuduntu\ndoes not. I uncommented each of the baseurl statements (there are\nthree) in each of the RPMFusion .repo files (there are four files,\nfree, non-free, free-testing, and non-free testing). I then re-ran\n'yum update', this time I was told the paths for the RPMFusion\nbaseurl's didn't exist. I opened up the path in a browser and\nconfirmed it was indeed wrong. I pruned sub directories from the path\none by one until I found a truncated url that actually existed on the\nRPMFusion FTP server. I looked at the .repo files again and figured\nout the paths referenced included global environment variables the\nwere inconstant between Fedora and Fuduntu. For instance, $release in\nFedora would return a value like 15, 16, or 17, where in Fuduntu it\nresolves to 2012. I figured if I took the time, I could walk up and\ndown the FTP server and come up with literal paths to put in the\nRPMFusion .repo files, but instead I just moved the involved .repo\nfiles into another folder to be dealt with another day. \n

      \n


      \n

      \n

      I again launched 'yum update'. This\ntime had no errors, but I was getting an excessive amount of new\nfiles from my new pbone.net repo ('yum update' updates your sources\nand downloads changed files all in one operation). It's possible the\nrolling Fuduntu is closer Fedora 16, so when I told pbone.net I was\nrunning 17, all the files in the alternate repo were newer than what\ni had. In any case, I had no wish to be dependent of a repo I had to\nrent at $3 a month, so I canceled the operation, admitted defeat, and\nstarted downloading the 64bit version of Lubuntu. I know I said I\nwould rather have a more challenging distro, but because of it's\nlocation, this needs to be a just works PC, not a hack on it for half\na day box. I would have like to have given Mageia, Rosa, or PCLinuxOS\na shot, but too many packages from outside the repos (case in point,\nHulu Desktop) are only available in Debian and Fedora flavors. You\nknow the rest, I installed Lubuntu, borked my Grub, loop back to the\ntop of the page.

      \nThe split command is used to split up a file into smaller files. For example, if you need to transfer a 3GB file but are restricted in storage space of the transfer to 500 MB you can split the 3GB file up into about 7 smaller files each 500MB or less in size. Once the files are transferred restoring them is done using the cat command and directing the output of each file back into the master file:
      \n
      \nsplit -b500M some3GBfile\n      \n

      I recently discovered apt shell\n(aptsh), a psuedo shell which gives users of distributions which use\napt for package management quick access to the functionality of\napt-get. You should find aptsh in the repositories of Debian based\ndistros. Once installed, you can launch 'aptsh' as root from the\ncommand prompt (i.e. 'sudo aptsh').

      \n


      \n

      \n

      \nOne of the drawbacks of installing software from the terminal is that\nsometimes you don't know the exact name of the package you want to\ninstall. From the aptsh> prompt, 'ls' plus a search string will\nshow all the packages that have that string in their names. You can\ntype 'install' plus a partial package name and use TAB completion to\nfinish the instruction. The function of the 'update' and 'upgrade'\ncommands are self explanatory, unfortunately, you can't string them\ntogether on the same line like you can in bash:

      \n


      \n

      \n

      sudo apt-get update && sudo\napt-get -y safe-upgrade \n

      \n


      \n

      \n

      Instead, you use the backtick [ ` ] key\nto put aptsh into queue mode. In queue mode, you can enter commands\none by one to be launched in sequence at a later time. To bring your\nsystem up to date, you could run:

      \n


      \n

      \n

      aptsh> ` \n

      \n

      * aptsh> update \n

      \n

      * aptsh> upgrade \n

      \n

      * aptsh> ` \n

      \n

      aptsh> queue-commit-say yes \n

      \n


      \n

      \n

      Backtick toggles queue entry, and\nqueue-commit runs the queue. “queue-commit-say y” tells aptsh to\nanswer in the affirmative to any queries from the commands executed\nin the queue in much the same way “apt-get -y safe-upgrade”\nconfirms software updates without user interaction. Apt shell is\ncapable of other apt related tasks, but I think I've covered the most\nuseful ones.

      \n


      \n

      \n

      The trouble with running aptsh is that\nunless you start it in a terminal with the computer and leave it\nrunning all day (as opposed to opening it as a new shell within you\nterminal every time you want to update or install), despite the\nconvienience of package name search and TAB completion, it really\nwon't save you any keystrokes. With that in mind, I started looking\nfor ways to have the apt shell available at a keystroke (we will\nleave the wisdom of leaving a shell open with a subset of root\nprivileges for another day). I had guake installed, but rarely used\nit because I usually have multiple terminal tabs open since I am\nlogged into my server remotely. [Actually, I had forgotten guake\nsupports tabbed terminals quite well. You can open a new tab with\n<Shift><Ctrl>T and switch between terminal tabs by\n<Ctrl><PgUp> and <Ctrl><PgDn> or clicking\nbuttons that appear at the bottom of the guake window. I had how,\nforgotten this until doing further research on this story. Since\nthis revelation ruins my story, we will forget about tabbed terminal\nsupport in guake and not mention it again.]

      \n


      \n

      \n

      I am also going to assume everyone is\nfamiliar with guake. If not, suffice it to say guake is a terminal\nthat pops down in the top third of the screen when you hit a hotkey,\n<F12> being the default. It returns to the background when you\npress <F12> again or click the lower part of the desktop. It\nis patterned after the command shell in the game Quake that let you\ninput diagnostic and cheat codes, hence the name. Since I wasn't\nusing guake as a terminal anyway, I wanted to see if I could make it\nrun apt shell by default. I found you can access guake's graphical\nconfiguration manager by right clicking inside the open terminal and\nselecting preferences. \n

      \n


      \n

      \n

      On the first preferences tab, I found\n“command interpreter”, but since aptsh is only a pseudo shell, it\nisn't found in the dropdown list. However, one option was “screen”,\nwhich would give me a way to run multiple terminals that I thought\nguake lacked. Next, I had to look up how to configure screen. I\nfigured there must be a way to make screen run aptsh in one session\nby default, and I found it. In the show notes I've included my\n.screenrc file from my home folder, which I make with the help of\nthis article from the online Red Hat Magazine: \n

      \n

      \n

      The first two lines set up the screen\nstatus line, the first puts it at the bottom of the terminal, the\nsecond sets up the status line to display the hostname and date, and\nan indicator that highlights which screen windows you are looking at.\n The # Default screens section below sets up sessions screen opens by\ndefault. The first line opens up a regular terminal named “shell1”\nand assigns it to session zero. The second opens a window called\n“apt-shell” (this is how it's identified on the status line) and\nlaunches apt shell. The last two log me into my server (host name\naliasing made possible by configuring my homefolder/.ssh/config ,\nthanks Ken Fallon) and my laptop running Fedora respectively. I\nstill have to cycle through your screen windows and type in my\npasswords for sudo and ssh. The configuration could be set up to\nlaunch any bash command or script by default. The cited article\ndoesn't include any more configuration tips, but I'm certain there\nare ways to set up other options, such as split windows by default. \n

      \n


      \n

      \n

      Since I also run screen on my remote\nconnection to my server, I have to remember the command prefix is\n<Crtl>a,a. Ergo, if I want to move to the next window in the\nscreen session (running under guake) on the local PC, the command is\n<Ctrl>a, then n. To go to the next screen window in the screen\nsession on my server, running inside another screen session on my\nlocal PC, it's <Ctrl>a,a,n. \n

      \n


      \n

      \n

      So, that's how I learned to run apt\nshell inside screen inside guake. I can be contacted at\nFiftyOneFifty@linuxbasement.com\nor by using the contact form on TheBigRedSwitch.DrupalGardens.Com

      \nHoly cow! I just interviewed RMS! Check it out.\n

      \n

      \nI tried to conduct a friendly interview with Richard here. Every time I've heard him interviewed before, it's been pretty hostile, and I didn't want that. That doesn't mean that I only asked him softball questions, but I didn't get in his face about anything, and I gave him the time he needed to explain his answers fully. I hope I did a good job of making Mr. Stallman feel welcome at Hacker Public radio, and I hope the interview is as enjoyable to listen to as it was to record. His views on Free Software are pretty well known, so I tried to cover some things that I've never heard Richard's opinoins on as well. I KNOW... I missed some pretty obvious followup questions. I realized most of them while editing. I'm sorry. The good news is that RMS is pretty accessable, and you can probably get him to do a followup interview that we'll publish right here on hackerpublicradio.org . \n

      A few months ago I went on a longer trip, alone in my car. As many podcasters before me, I decided to record an episode. An episode I almost immediately forgot about. Fast forward to a couple of weeks ago, when I once again found the recording. It sounded quite bad, but after some sound wizardry I think it can pass for an HPR show. The content is where it's at, after all.

Please help to improve this article by introducing more precise citations. (March 2008)\nThe Apple Filing Protocol (AFP), formerly AppleTalk Filing Protocol, is a proprietary network protocol that offers file services for Mac OS X and original Mac OS. In Mac OS X, AFP is one of several file services supported including Server Message Block (SMB), Network File System (NFS), File Transfer Protocol (FTP), and WebDAV. AFP currently supports Unicode file names, POSIX and access control list permissions, resource forks, named extended attributes, and advanced file locking. In Mac OS 9 and earlier, AFP was the primary protocol for file services.

      \nThe kill command is used in the shell to terminate a process. Kill works by sending a signal to the process and typically this signal is either the SIGTERM or SIGKILL signal, but there are others that can be used. To properly use the kill command you need to know the Process ID, or PID, of the process you want to kill. Also be aware that some processes can spawn child processes of the same or similar name. For instance, if you have are running the Chromium browser you may find multiple instances of the chromium process running. Killing one of these processes may not terminate all the processes because typically all but the first process are children processes. Killing any or all of the children processes will not terminate the mother process. But terminated the mother process will typically kill the children processes.\n

      This Beginners' guide will show you how to add data to\nOpenStreetMap. Tutorials are available in many languages which you\ncan select from the table at the top of this page. \n

      \n

      You need a computer connected to the Internet and some time to\ngather information and then enter it. A GPS unit and connecting cable\nare purely optional, but will be required if you want to collect data\nthat way. Given the excellent aerial photography available in the\neditors these days a GPS is less important than in the early days of\nthe project. \n

      \n\n

      The data you add to OpenStreetMap improves the free world map for\neveryone, whether it's a small correction or thousands of roads added\nover time. Thank you for making OpenStreetMap just that bit better! \n

      \n

      There is a panel on the right of every page of the tutorial. The\npage you are on will be in bold text and you can move to any other\npage by clicking on the relevant page title. The bottom of each page\nhas 'next' and 'previous' links, as appropriate, to take you through\nthe tutorial page by page. \n

      Programming languages 2 - Getting started with Python

      \n\n\n\n\nPython is a very interesting language in the sense that it covers a\nvery wide range of use cases. \n
        \n
      1. It can be useful for simple scripting tasks, that is automating\n repetitive tasks that you usually do by hand.\n
        2. \n
      2. It can also be useful for text file processing, like parsing log\n files or specific formats like XML.\n
        3. \n
      3. You can use use it as a glue language, that is a mix of system\n calls to command-line programs, like in scripting, but also by\n calling foreing language libraries which provide Python bindings.\n
        4. \n
      4. You can use Python as a first language in a Computer Science\n curriculum, since it is simple to learn and supports different\n programming paradigms (Object Oriented, Procedural, Functional).\n
        5. \n
      5. You can it also as an extension language, since a Python\n interpreter can be embedded in C/C++ programs.\n
        6. \n
      6. Python being a very rich language with a very rich standard\n library, you can use it to build very complex applications. There\n are many ways of using it to build complex Graphical User\n Interfaces, since many graphical libraries provide Python bindings\n (https://www.diotavelli.net/PyQtWiki/PyQt4, GTK, etc.). Python also\n provides a default library for GUIs, which is called Tkinter and is\n based on Tcl/Tk.\n
        7. \n
      7. You can also use Python for web development, either by using the\n standard library utilities or by using one of the very popular web\n frameworks like Zope, Plone or Django.\n
        8. \n
      8. Finally, Python is also extensively used in scientific computing,\n since projects like SciPy, Numpy or Matplotlib provide a set of\n tools which allow Python to be as powerful as languages like Matlab\n or IDL with the advantage of being a full fledged language with a\n very rich standard library.\n
        9. \n
      \n\n\n

      2 Installation

      \n

      \nThere are 2 current versions of Python: version 2 and\nversion 3. Version 3 is not fully compatible with version 2, so if you\nare starting with Python, I think is is wise to go with version 3, but\nbe aware that most existing applications and Open Source projects use\nversion 2.\n

      \n

      \nIf you are using a GNU based system, chances are that Python is\nalready installed in you system. Otherwise, it will be available in\nyour distribution repositories. As far as I know, Python is also\navailable on the Mac via the terminal. On widows, you will have to\ndownload a Python distribution from https://python.org/download. On\nthis page you will also find links for downloading Python for Linux,\nMacOS, etc.\n

      \n

      \nIf you go to this site, you will notice that they mention alternative\nimplementations of Python. The implementation I will be talking about\nhere is the one done in C.\n

      \n

      \nTo install Python, you also can download the source code and compile\nit yourself.\n

      \n\n

      3 Syntax and semantics

      \n\n

      \nHave a look at this link\n

      \n

      \nPython is intended to be a highly readable language. It is designed to\nhave an uncluttered visual layout, frequently using English keywords\nwhere other languages use punctuation. Python requires less\nboilerplate than traditional manifestly typed structured languages\nsuch as C or Pascal, and has a smaller number of syntactic exceptions\nand special cases than either of these.\n

      \n

      \nThe simplicity of Python is demonstrated by its version of the classic\n\"Hello world\" program:\n

      \n

      \nprint(\"Hello world\")\n

      \n

      \nIndentation\n

      \n

      \nPython uses whitespace indentation, rather than curly braces or\nkeywords, to delimit blocks; a feature also termed the off-side\nrule. An increase in indentation comes after certain statements; a\ndecrease in indentation signifies the end of the current block.\n

      \n

      \nStatements and control flow\n

      \n

      \nPython's statements include (among others):\n

      \n

      \n The if statement, which conditionally executes a block of code,\n along with else and elif (a contraction of else-if).\n

      \n

      \n The for statement, which iterates over an iterable object,\n capturing each element to a local variable for use by the attached\n block.\n

      \n

      \n The while statement, which executes a block of code as long as its\n condition is true.\n

      \n

      \n The class statement, which executes a block of code and attaches\n its local namespace to a class, for use in object-oriented\n programming.\n

      \n

      \n The def statement, which defines a function or method.\n

      \n

      \n The import statement, which is used to import modules whose\n functions or variables can be used in the current program.\n

      \n

      \nEach statement has its own semantics: for example, the def statement\ndoes not execute its block immediately, unlike most other statements.\n

      \n

      \nExpressions\n

      \n

      \nPython expressions are similar to languages such as C and Java.\n

      \n

      \n In Python, == compares by value, in contrast to Java, where it\n compares by reference. (Value comparisons in Java use the equals()\n method.) Python's is operator may be used to compare object\n identities (comparison by reference). Comparisons may be chained,\n for example a <= b <= c.\n

      \n

      \n Python uses the words and, or, not for its boolean operators\n rather than the symbolic &&, ||, ! used in Java and C.\n

      \n

      \n Conditional expressions in Python are written as x if c else y\n (different in order of operands from the ?: operator common to\n many other languages).\n

      \n\n

      \nMethods\n

      \n

      \nMethods on objects are functions attached to the object's class; the\nsyntax instance.method(argument) is, for normal methods and functions,\nsyntactic sugar for Class.method(instance, argument). Python methods\nhave an explicit self parameter to access instance data, in contrast\nto the implicit self in some other object-oriented programming\nlanguages (for example, Java, C++ or Ruby).\n

      \n

      \nTyping\n

      \n

      \nPython uses duck typing and has typed objects but untyped variable\nnames. Type constraints are not checked at compile time; rather,\noperations on an object may fail, signifying that the given object is\nnot of a suitable type. Despite being dynamically typed, Python is\nstrongly typed, forbidding operations that are not well-defined (for\nexample, adding a number to a string) rather than silently attempting\nto make sense of them.\n

      \n

      \nPython allows programmers to define their own types using classes,\nwhich are most often used for object-oriented programming. New\ninstances of classes are constructed by calling the class (for\nexample, SpamClass() or EggsClass()), and the classes themselves are\ninstances of the metaclass type (itself an instance of itself),\nallowing metaprogramming and reflection.\n

      \n\n

      4 Interpreter

      \n\n

      The section 3 of the python tutorial (An informal introduction to Python) gives a very good overview of the use of the interactive interpreter.\n

      \n

      \nOf course, if you are going to write long programs, you will want to\nsave them to files which can then be passed to the interpreter for execution.\n

      \n\n

      5 Standard library

      \n\n

      Python has a very rich standard library, that is a set of modules\nwhich are part of the standard Python installation and which provide\nmany interesting functions which in many other languages are only\nprovided by 3rd party libraries :\n

Intro to Recreational Math","duration":1365,"summary":"Intro to Recreational Math Part Zero","notes":"
      \nHacker Public Radio: 206 203 5729\n\nThe N Days of Christmas? Intro to Recreational Math\nPart Zero: Calendar Counting\n\nFirst episode of HPR that contains a direct discussion of a math topic.\n - Episode 479 Ohio Linux Fest, Klaatu interviews DWick about math \n      software for Linux\n      \n - Episode 523 Using Petunia software to teach math\n\n\nInspired by a traditional song that is proof that some songs do not\n   need to be recorded by William Shatner to be annoying.\n - Repetitive and formulaic\n - Involves a lot of counting, and that's our focus here. \n \n \nWhat is the 12 Days of Christmas?\n - Starts on Christmas Day, runs through the day before the next Season\n - Hint: That's 'Epiphany', which starts January 6.\n - Counting calendar days comes hard, so we tend to use our fingers\n - Turns out that using our fingers is quite mathematical. Here's why.\n \nFinger Counting: How do I count Twelve Days?\n - Let's start easy, with the fingers on one hand. My hands have five.\n - To name the Five Days of New Years is easy: January 1-5 <done>\n \n - What about the Five Days of Christmas?\n        Physical way                   General way\n   * Christmas Day gets 1 (thumb)     Dec 25 is one day after Dec 24\n   * Dec 26 gets 2 (index)            26 - 24 = 2 days\n   * Dec 27 gets 3 (salute finger)    27 - 24 = 3 days\n   * Dec 28 gets 4 (ring)             28 - 24 = 4 days\n   * Dec 29 gets 5 (pinky)            29 - 24 = 5 days\n \n - Notice that counting 5 days, starting with Dec 25, is the same\n     as numbering the days after Dec 24 (Christmas Eve).\n   * In math, we call this \"1-1 correspondence with natural numbers\"\n   * Math can give you the same certainty as using your fingers.  \n   * But it handles larger problems, because you don't run out.\n \n - Example: I'm booked to speak on Day 4 of a 5-day conference\n   * Starts on the 25th of the month\n   * When do I have to show up?\n     - Wrong: Add 4 to first day (25), and arrive a day late.\n     - Correct: Add 4 to date of pre-registration cocktail party (24),\n          and arrive on time.\n      \n - OK. Back to Twelve Days of Christmas.  \n   * The labeling approach tells us that December can hold only the \n       first seven of the Twelve Days of Christmas, \n   * December 31 - December 24 gives me 7 days.\n \n \n Partitioning: Adding hands full of additional fingers as needed\n  - How do we handle the case where we go into the next month?\n  - Key insight: Running out of December days for the Twelve Days is \n       like running out of fingers on one hand when we count to 8.\n  - We are so good at counting on our fingers that we don't recognize \n       the act of partitioning the number 8 between our two hands.\n    *  Left hand gets 1, 2, 3, 4 and 5.\n    *  Right hand picks up 6, 7 and 8 by mapping them to fingers 1,2,3.\n\n  - To count even higher, we could:\n      1) keep borrowing other people's hands, or\n      2) track the number of times we reuse our two hands as we go\n    \n    * First method mirrors calendar math (\"Annexing\" hands, or months)\n    * Second is positional notation (\"base 10\" and all that)\n\n\nBack to the Twelve Days\n - I have Twelve Days: 1, 2, ... 12 to assign to dates, even though I \n     may only be interested in the first and last dates right now.\n   * Start: How many can I fit into December?\n   * December 31st is last. It gets assigned 31 - 24, or 7. \n   * By \"finger math\", that means I have mapped 7 of the Twelve Days\n   * That leaves 12 - 7, or 5 days into January.\n \n - Who can tell me which days are assigned in January? Anyone?\n   * That's right, Ken.  January 1, 2, 3, 4 and 5.\n   * So the Twelve Days of Christmas runs 25 December to 5 January \n\n\nQuestion: What if there were 72 Days of Christmas?  When would it end?\n - Note: Don't worry.  This is purely hypothetical.\n\n - Let's attack this with finger math, with partitioning and annexing\n   * December, as we have seen, accounts for 7 days: 25 through 31\n   * That leaves 72 - 7, or 65 days\n   * January easily picks up 31 days: 1 to 31, leaving 65 - 31 = 34 days\n   * February can handle either 28 days, or 29 on a leap year.\n   * This leaves us either 5 or 6 days into March\n\n - Final Answer: 72 Days of Christmas would run from Christmas until the\n     following March 5 (leap year), or March 6 (all other years).\n   * On Day 73, everyone would enter treatment for Christmas overdose.\n\nLet's check the answer: Day 72 would end ten weeks and 2 days after \n   the opening cocktail party (Monday). So Day 72 should be Wednesday.\n   * Next year is not a leap year, so last day is March 6.\n   * By the Doomsday perpetual calendar method, Feb 28 is Thursday.\n   \n   Doomsday method: https://en.wikipedia.org/wiki/Doomsday_rule\n   \n   * So March 7 is Thursday, and March 6 is Wednesday.\n   * It worked.\n \nWhy should I bother with Calendar Math?\n - I learn to look for ways to partition hard problems into easier ones.\n - I learn the same skills that I'll need to debug \"off-by-one\" errors\n     and other boundary violations, which kill you in C programs.\n - I will never miss a speaking engagement, as long as I count my \n     Conference Days from the cocktail party, not from the Keynote.\n\n\nNext episode: Part One\n  Counting partridges and gold rings with Pascal\n  - Warning: There will be two semi-magic formulas at the end.\n  - I'll show you an easy way to do running sums in a spreadsheet.\n  - You can skip the formulas, and I'll never know.\n  - Since this is HPR, not school.  We can look up the formulas.\n\n\nContact: Charles in NJ\nEmail: catintp@yahoo.com\n\nCharlie + Alpha + Tango + India + November + Tango + Papa.\n\n

      Indie and Creative Commons

      \n
        \n\t
      • Soundcloud - This is a music and audio sharing site, primarily.
        • \n\t
      • Free Music Archive - Lots of CC-licensed music.
        • \n\t
      • Jamendo - One of the premiere CC music sites.
        • \n\t
      • Bandcamp - I just learned about this site from my friend Craig Maloney, who does the Open Metal Cast. This site has Creative Commons music from bands who want to build a relationship with their fans and sell them music. Good artists like Amanda Palmer are here.

      e-Books

      \nWhen it comes to books, you really are at the mercy of the individual publishers. Most music labels have finally come to accept that no DRM is the best way to go, but must book publishers are still being dragged into the 21st century kicking and screaming. But there are some good places to find e-books that respect your freedom.\n
        \n\t
      • Project Gutenberg - This is the granddaddy of the DRM free book sites. Project Gutenberg makes available books that are in the Public Domain, i.e., where the copyright has run out. These are mainly older books, but a lot of classics are in here. They make books available in all of the major formats.
        • \n\t
      • Baen Books - This publisher specializes in the harder Science Fiction, but they really understand the new media landscape. They not only offer most of their books DRM-free and in multiple formats, but they also have the Baen Free Library, where they offer selected books free of charge. The hope is that with the first taste free, you will want to buy more. And it works. I went there to see what they had, discovered that they had the entire collected works of one of my favorite authors (James H. Schmitz) for sale, and bought the lot of them.
        • \n\t
      • Tor/Forge - A major publisher in the Science Fiction and Fantasy fields, they just moved to going DRM free a few months ago. They did this because other publishers had been successful in so doing.
        • \n\t
      • Angry Robot - Along with Baen, a pioneer in selling DRM-free books in the Science Fiction and Fantasy fields.
        • \n\t
      • Avon Romance - A major publisher of romance novels, they just announced that they are experimenting with DRM-free ebook sales.
        • \n\t
      • O'Reilly Media - The premiere publisher of technical books, they pretty get everything right. They sell e-books without DRM. When a new edition of a book you already bought comes out you can \"upgrade\" for a nominal fee (e.g. I upgraded my Kevin Purdy \"Android\" book for $1). And with older books that they think are no longer worth in print, they are removing the copyright and making them freely available.
        • \n\t
      • ManyBooks.net - This site has a lot of overlap with Project Gutenberg, but also has some newer works that have been made available, such as Charles Stross's Accelerando.
        • \n\t
      • Fictionwise - Although heavy on the Science Fiction and Fantasy, has a lot of offerings in other genres as well. Reasonably priced and DRM-free.
        • \n\t
      • Cory Doctorow - Cory was one of the first authors to make a point of offering all of his works not only DRM-free but free of charge in e-book formats from his Web site. But you know, when the book he co-authored with Charles Stross Rapture of the Nerds came out recently I went to the Google Play store and bought it.
        • \n\t
      • DriveThru Fiction - An interesting site that also has Comics and RPG games available.
        • \n\t
      • Apress - A publisher of technical books that also offers reduced-price e-books if you have already purchased the print title. This is something I'd like to see more of.
        • \n\t
      • Packt Publishing - Another technical book publisher with DRM-free books.
        • \n
      \n

      Audiobooks

      \nThis is where there is still a big disappointment. Audible, which is by any measure the clear leader here, insists on DRM on all of their books, which is why I refuse to get an account. Audible is now owned by Amazon, which sells music tracks as MP3 files without DRM, so there was hope when they bought Audible that we could get DRM-free audiobooks, but that was not the case. Fortunately, there are alternatives.\n
        \n\t
      • eMusic - This is the same site I mentioned above for DRM-free music tracks. They also offer a subscription plan for audiobooks, $10 a month gets you one book. Selection is not as good as Audible, but their list is growing all of the time and I have had no trouble finding books there that interest me. I recently listened to Walter Isaacson's biography of Albert Einstein through a book I bought here.
        • \n\t
      • Podiobooks - This site offers audiobooks in serialized form, much like podcasts offer you a file every week. Heavy on the Science Fiction and Fantasy at this point, but worth checking out. Scott Sigler and J.C. Hutchins are both available here, for instance.
        • \n\t
      • Scott Sigler - Scott used free content to get his name out, but still offers free audio versions on his web site even though he now has a publisher.
        • \n\t
      • Cory Doctorow - Cory in addition to offering free ebooks also offers audiobooks that are DRM-free on a \"name your own price\" basis. Among the readers on his books are Neil Gaiman, Wil Wheaton, Spider Robinson, and Leo Laporte. He even sells files and CDs in Ogg format if you prefer to get your files that way. Due seriously gets freedom, but if you know anything about Cory Doctorow you know that.

      Protocols 101 Wikipedia thinks it is long but not as\nlong as college courses but it covers the basic level stuff\nbut the article should open the rabbit hole a bit.\nhttps://en.wikipedia.org/wiki/Communications_protocol\n

      \nI am trying to write a script which will implement the scheduling rules for\nHPR. I spoke to Ken Fallon about this, and where it would fit in the overall\ndesign of the HPR system, when we met up at OggCamp 2012 in August, but we\ndidn't manage to resolve very much. So, recently Ken and I began a discussion\nover Mumble to try and make progress. A few minutes in we decided to record\nour discussion for posterity, and this is the result.\n

      \nI recently ran an educational event for a society concerned with Mysticism \nand as such, gave the first speech. I recorded it \"on the fly,\" so there \nare problems with the recording, and I had to cut a few comments that \nwere too soft to be picked up at all by my head-mounted microphone. \n\nWhat follows is the script I wrote for the first three-quarters of the \npresentation.\n\n==================================================================\n\nThe first thing to understand is that we are not really discussing the \ntraditional idea of forgiveness.  We are talking about a whole new \nballgame. This really is not your parents idea of forgiveness.  Let's \nhave an example of old-school forgiveness.\n\n\"Well, you really did it. This is a real, and a really bad, situation, \nand it happens to be your fault. But I'm going to forgive you for what \nyou did. You don't deserve this, but I'm just so much more perfect than you, \nI'm going to do this anyway. Because I have Jesus. By the way, you don't.\nAnd you will always be screwing up. You could stop screwing up, but \nyou wont. Because your not as great a person as I am. You could begin \nto agree with me about everything, but you won't. You could even \nbelieve every last thing I believe. But you won't. So, unlike me, \nthere is no hope of you going to heaven. I will, but you wont. And \nI might not look sad about this, but I really do feel sorry for you.\"\n\n

      \nA Contribution for HPR from Dude-man@dudmanovi.cz where he talks about a not so well known, but very well thought out and backed up by scientific research started in the 1930's by Weston A Price, who went on after traveling around the world to find healthy people and study what made them healthy to write a large book describing in a language understandable to the lay person what he discovered along with its significance in our own lives should we wish to maximize our health and that of our children and future generations. Of course the first question we should have is what does a healthy person look like, the shape and size, the condition of the teeth etc.\n

      \n

      \nDude-man does his best to share a little of what he's learnt over the last 10 years which he's been putting into practice with his wife, son (7), daughter (2) and their small homestead of Jersey dairy cows and other animals which help provide the staff of life to the whole family.\n

        • \n
        \n
      • Add/modify the following stanza to SSH server configuration:
        \nChallengeResponseAuthentication yes
        • \n
        \n
      • Create Google two factor profile for SSH user and answer the setup questions based off your preferences
        \n$ google-authenticator
        • \n
        \n
      • Restart SSH server
        \n$ service ssh restart (on CENTOS try $ service sshd restart)

      Wrap Up
      \n
        \n
      • In Debian based systems you can comment out the system wide common-auth by simply adding a # to the beginning of the @include common-auth.
        • \n
      • If you want to use google two auth with other applications simply add it to the appropriate /etc/pam.d/ file
        • \n
      • Other useful PAM modules include the Barada module: libpam-barada (OTP with Android Client), pam_winbind (Samba Active Directory authentication module), and many more.
        • \n
      • Make sure you have dual SSH connections and are sudo or su as a privileged user. Also make sure any files you configure today are backed up before you edit them.
        • \n
      • When setting up Two Factor Auth profiles, go into cleanup mode to ensure you don't use the QR code url where it can be later retrieved from your url history. Also make sure you cleanup your command line and clipboard history so that emergency scratch codes and secret keys can't be found by wondering eyes.

      Synopsis of the Problem

      \n\n

      \nYou may have heard me mention that I purchased a used rack server a couple years ago to help teach myself Linux server administration. It's an HP DL-380 G3 with dual single core Zeons and 12Gb of RAM. It came with two 75Gb SCSI drives in RAID1, dedicated to the OS. Since the seller wanted more for additional internal SCSI drives, and those old server drives are limited to 120Gb anyway, I plugged in a PCI-X SATA adapter and connected 750Gb drive externally and mounted it as /home. I moved over the 2Gb USB drive I had on my Chumby (as opposed to transferring the files) and it shows up as /media/usb0. I installed Ubuntu server 10.04 (recently updated to 12.04) because CentOS didn't support the RAID controller out of the box and I had frustrated the lack of support for up to date packages on Debian Lenny on the desktop.\n

      \n\n

      \nWith 75Gb dedicated to the OS and application packages, you can imaging\nmy surprise when after a update and upgrade, I had a report that my\n/boot was full. It was until I look at the output from fdisk that\nI remembered the Ubuntu installer created a separate partition for\n/boot. At the risk of oversimplifying the purpose of /boot, it is\nwhere your current and past kernel files are stored. Unless the\nsystem removes older kernels (most desktop systems seem to) the storage\nrequired for /boot will increase with every kernel upgrade.\n

      \n\n

      This is the output of df before culling the kernels

      \n\n

      The Solution I Found

      \n\n

      I ran across some articles that\nsuggested I could use 'uname -r' to identify my current running kernel\n(3.2.0-31, the -32 apparently kernel ran out of space before it\n completed installing) and just delete the files with other\nnumbers. That didn't seem prudent, and fortunately I've found\nwhat seems to be a more elegant solution on upubuntu.com .
      \nhttps://www.upubuntu.com/2011/11/how-to-remove-unused-old-kernels-on.html
      \n

      \n\n

      Verify your current running kernel

      \n\n
      uname -r\n
      \n\n

      Linux will often keep older kernels so that you can boot into and older\nversion from Grub (at least on a desktop). Fedora has an\nenvironment setting to tell the OS just how many old kernels you want to\nmaintain [installonly_limit in /etc/yum.conf]. Please leave a\ncomment if you know of an analog in Debian/Ubuntu.\n

      \n\n

      List the kernels currently installed on you system.

      \n\n
      dpkg --list | grep linux-image\n
      \n\n

      Cull all the kernels but the current one

      \n\n

      \nThe next line is the key, make sure you copy and paste exactly from the\nshownotes. I'm not much good with regular expressions, but I can\nsee it's trying to match all the packages starting with 'linux-image'\nbut containing a number string different from the one returned by\n'uname -r', and remove those packages. Obviously, this specific\ncommand will only work with Debian/Ubuntu systems, but you should be\nable to adapt it to your distro. The '-P' is my contribution, so\nyou can see what packages you are eliminating before the change becomes\nfinal.\n

      \n\n
      sudo aptitude -P purge ~ilinux-image-\\[0-9\\]\\(\\!`uname -r`\\)\n
      \n\n

      Make sure Grub reflects your changes

      \n\n

      Finally, the author recomends running 'sudo update-grub2' to make sure\nGrub reflects your current kernel status (the above command sees to do this\nafter every operation anyway, but better safe than sorry.

      \n\n

      It's worth noting I still don't have my -32 kernel update, so I'll let\nyou know if the is anything required to get kernel updates get started\nagain.\n

      \n\n

      My df now shows 14% usage in /boot and a directory listing on /boot only shows the current kernel files.\n

      Hey listeners, another episode of Tech & Loathing is now on tap. A couple of IRC friends have joined me tonight to discuss a couple of topics. For Loathing we have Android vs. iOS and all of my frustrations with the world of mobile computing. For Tech we have a look at RDP, VNC and running applications and desktop environments remotely, either securely via SSH or VPN or insecurely using X Forwarding and other techniques. Hope everyone enjoys the show.

      The sort command does just that, it sorts input.  Input can be a list of files, standard in, or files with standard in. The first example presents this simple file, shopping.txt,  containing a list of items:

      chicken

      Issuing the sort command on this file:

For this episode to work, I'll need your cooperation, and for it to make any sence to you, you'll need to be signed into https://www.openstreetmap.org/ .

      The date command will not only display or let you change the current date and time but is the go-to utility for getting date and time information into scripts. Invoked by itself the date command will output the current system date based upon the rules of the LC_TIME format. The LC_TIME format defines the rules for formatting dates and times. LC_TIME is a subset of locale which defines the overall environment based upon the chosen language and cultural conventions. You can see the current LC value by issuing the locale command. You can see time specific information for your system by issuing:

      \n

      locale -m LC_TIME

      \nIn todays show Ken catches up with Chris Conder of the Broadband for Rural North (https://b4rn.org.uk/). We interviewed her back in episode 980 (https://hackerpublicradio.org/eps.php?id=0980)
      \n\"A\n

      \n

      \nLocated in the very pretty but the rural Forest of Bowland in Lancashire in the UK, and tired of putting up with slow \"broadband\" they decided to put together their own network. They tried shared wifi, 3 and 4G mobile networks, MMDS and Satellite yet all proved to be unreliable.\n

      \n

      \nSo over tea and cake they came up with a plan.

      \n
        \n
      • A 240 Kilometer (150 mile) plan.
        • \n
      • A 1 gigabit (1000mb/sec) fiber optic connection plan.
        • \n
      • A let's give a connection to every one of the 1700 homes, farms, schools, churches and businesses, in the area plan
        • \n
      \n

      And while they were at it they designed it to be:

      \n
        \n
      • redundant with a dual homed backbone direct to the UK's Internet exchange
        • \n
      • upgradeable with ducts large enough to take multiple fibers
        • \n
      • laid through some of the most rugged, mountainous area of Lancashire to get to the people that need it most. (And let's be clear here, nothing to do with the fact that they will need to use dynamite to blast their way through the rocks.)

      \n
      \nI recently learned where Linux stores the PPD created when you set up a\nprinter and how to copy it between PCs.  I'd like to briefly share\nthat information with you.
      \n
      \n\n\nThis is how to copy a printer definition file (equivalent of a printer\ndriver) from a system where the printer is already configured to\nanother system that you want to be able to access the same\nprinter.  Reasons you might need to do this:
      \n
      \na.  The normal CUPS (Common Unified Printing System) set up\ndoesn't have the right definition file for your printer.  In rare\ninstances, you might have to download a ppd from the manufacturer or\nanother source.  If so, copying the ppd may be easier than\ndownloading it again.
      \n
      b.  You configure CUPS and find there are no pre-provided\nprinter\ndrivers.  I thought this was the case when I first tried to\nconfigure CUPS under Linaro on my ODroidX.   For all intents and\npurposes, Linaro is an Arm port of mainline Ubuntu (Unity\nincluded).  I installed CUPS via Aptitude and tried to configure a\nprinter as I would on any Linux system.  When I got to printer\nselection, the dropdown to select a\nmanufacturer (the next step would be to choose a model) was greyed out,\nas was the field to enter a path to a ppd file.  I closed the\nbrowser and tried again, and the same thing happened.  This is\nwhat prompted me to find out where to find a PPD file on another system\nand copy it.  I never got to see how it would work, because when I\nhad the ppd file copied over and ready to install, the\nmanufactures and models in CUPS were already populated.  There had\nbee an update between my first and second attempts to configure CUPS on\nthe ODroidX, but I'd rather say it was a glitch the first time, instead\nof the ppd's suddenly showing up in the repo.
      \n
      \nc.  When I installed Arch on another system, I found there was far\nless options for choosing models, in my instance, there was only one\nselection for HP Deskjets.  I suspect borrowing the model specific\nppd from another distro will increase the functionality of the printer.
      \n
      \nCopying the ppd
      \n
      \n1.  On the computer where the printer is already configured, find\nthe .ppd (Postscript Printer Definition) file you generated (filename\nwill be the same as the printer name) in /etc/cups/ppd/model (or\npossibly just /etc/cups/ppd, neither my ODroidX or my Fedora laptop\nhave the \"model\" folder).
      \n2. Copy to your home folder on the new system (You can't place the file\nin it's final destination yet, unless you are remoted in as root)
      \n3. According to the post I found on LinuxQuestions.org, CUPS looks for\na GZipped file [ gzip -c myprinter.ppd > myprinter.ppd.gz ; the '-c'\narguement creates a new file, rather than gzipping the old one, and you\nuse redirection to generate the new file.]  Recall that I never\ngot to try this, because when I re-ran CUPS, the printer selections\nwere already populated. 
      \n4. Copy the archived file to /etc/cups/ppd/model on the machine that needs the printer driver
      \n
      \nConfigure CUPS (IP Printer)
      \n1. Open localhost:631 in a browser
      \n2. Click Administration tab
      \n3. Click \"Add a Printer\" button
      \n4. Log in as an account with root priviledges
      \n5. For Ethernet printers, select \"AppSocket/HP JetDirect\" button and click \"Continue\"
      \n6. From the examples presented, \" socket://PRINT_SERVER_IP_ADDRESS:9100  \" works for me, click continue
      \n7. On the next page, fill in a printer name, this will be the file name\nfor the PPD generated as well as how the printer is labled in the\nprinter select dialog.  The other fields are optional.  Click\ncontinue.
      \n8. (I am assuming if the LinuxQuestions post was right, CUPS will find\nthe gz file and show the manuafacturer and model as options) From the\nlist, select a manufacturer, or input the path to your PPD file
      \n9. Select the printer model
      \n9a.I think you could copy over the ppd as is and type the path to it in the field where it asks for a ppd file. 
      \n10.Modify or accept the default printer settings
      \n
      \nOr just copy the ppd and compare the settings in /etc/cups/printers.conf
      \n

      \nThe OTR Fans site defines OTR as \"Old time radio often called \"OTR\" refers to radio shows from the early days of radio broadcasting. The term usually applies to dramas, comedies, mystery shows, westerns and variety shows that were acted out by professional actors and sent out over the airwaves. In the golden age of radio families would sit around their radio listening to the exciting shows the way we sit around our television sets watching them today.\"\n

      \nI had an idea for a website that aims to explain as clearly as possible, computing and internet terms that confuse and frustrate people.\n

      \n

      \nIt came about when a Motorsport Forum Website I work with changed their IP address and some DNS issues caused problems. In the discussion amongst the staff of the site, as soon as the technically minded staff talked about DNS and IPs and Caches, some of the staff who aren't as familiar with the terms either dropped out or even got angry because they felt they were being excluded.\n

      \n

      \nThat highlighted to me the need for a resource where these terms could be explained in a way that demystifies the jargon for the every man. I am thinking it could be massively useful to have a site where we can use short video files to quickly and effectively explain the who,why,where,when and what of computerspeak, that would otherwise baffle and deter friends, family and colleagues.\n

      \n

      \nThis idea is little more than a concept at this time. As I make progress towards getting CJA working, I shall post updates on https://amunro.net\n

      \nIn today's show Chess talks to us about a static html generator written in perl called templer\n

      \n\n

      Templer

      \n\n

      Templer is yet another static site generator, written in Perl.

      \n\n

      It makes use of the HTML::Template module for performing variable expansion within pages and layouts, along with looping and conditional-statement handling.

      \n\n

      Templer has evolved over time for my own personal use, but I believe\nit is sufficiently generic it could be useful to others.

      \n\n

      My motivation for putting it together came from the desire to change\nseveral hand-made, HTML-coded, sites to something more maintainable such\nthat I could easily change the layout in one place.

      \n\n

      The design evolved over time but the key reason for keeping it around\nis that it differs from many other simple static-generators in several\nways:

      \n\n
        \n
      • You may define global variables for use in your pages/layouts.
        • \n
      • A page may define and use page-specific variables.
        • \n
      • You may change the layout on a per-page basis if you so wish.\n\n
          \n
        • This was something that is missing from a lot of competing tools.
          • \n
        \n
        • \n
      • Conditional variable expansion is supported, via HTML::Template.
        • \n
      • File contents, shell commands, and file-globs may be used in the templates\n\n
          \n
        • This allows the trivial creation of galleries, for example.
          • \n
        • These are implemented via plugins.
          • \n
        \n
        • \n
      • You may also embed perl code in your pages.
        • \n

      Another key point is that the layouts allow for more than a single\nsimple \"content\" block to be placed into them - you can add arbitrary\nnumbers of optional side-menus, for example.

      \n\n

      Although this tool was written and used with the intent you'd write your\nsite-content in HTML you can write your input pages in Textile or Markdown\nif you prefer (these inputs are supported via plugins).

      The Problem

      \n\n

      \nI'm a fan of Magnatune (https://magnatune.com/) and have been buying music\nfrom them for 7 or 8 years. The Magnatune website itself is good for exploring\nand downloading, and interfaces for browsing and purchasing are available in\na number of players on Linux. I have direct experience of:\n

      \n\n
        \n
      • Amarok: allows you to browse, purchase, examine artist information and album\n details.\n
      • Rhythmbox: the plugin, which used to allow browsing and purchasing, is\n currently unavailable, but is apparently due to return soon.\n
      • Gnome Music Player Client: (a front-end to the Music Player Daemon, mpd)\n offers a Magnatune browser plugin\n
      • Magnatune Web 2.0 player: a web-based tool which will browse, play and\n download Magnatune music.\n
      • Magnatune Android player: a fairly basic browser and player for Android 2.0\n and up.\n
      \n\n

      \nThe Magnatune Web 2.0 player is the best of the bunch as far as I am\nconcerned, particularly since it allows me to explore the music collection\nwhilst listening to streamed music at the same time. However, none of these\ninterfaces provide me with exactly what I want in terms of the download\nprocess, so I decided to write my own.\n

      \n\n

      The Plan

      \n\n

      \nI currently host my music on my HP Proliant microserver, share it across the\nhome network, and play it with the Music Player Daemon\n(https://sourceforge.net/projects/musicpd/) on my desktop system. I normally\nkeep the album cover image, artwork and related material in the same directory\nas the album itself, and I want to be able to save all files in their\nappropriate places automatically.\n

      \n

      \nMagnatune provides an API which is documented at\nhttps://download.magnatune.com/info/api, though this information is only available\nto members. Data is available in several formats: XML, SQlite and MySQL.\n

      \n\n

      Design

      \n\n

      \nI didn't want to launch into building a full-blown application, especially\nsince I only needed a downloader, so I decided to create a collection of\nBash and Perl scripts.\n

      \n

      \nI decided to use the XML data organised by album. This is updated on about\na weekly or two weekly basis, and there is a signalling mechanism through\na downloadable file containing a checksum. When this changes the large data\nfile has changed and can be downloaded. At the time of writing I simply run\nthis by hand when I receive an email alert from Magnatune.\n

      \n

      \nMagnatune uses an unique key made from the artist and album names which it\nrefers to as the SKU (Stock Keeping Unit) or albumsku. They use this\nas an URL component and in XML tags. I use it to identify the stuff I download\nand to keep a simple inventory.\n

      \n

      \nI decided to write some basic scripts:\n

      \n\n
        \n
      • To download the catalogue\n
      • To extract information from the catalogue\n
      • To download an album\n
      • To unpack the downloaded items into the target directory\n
      \n\n

      \nI wanted to learn more about manipulating XML data, so I decided to use\nXSL, the Extensible Stylesheet Language. This lets you define\nstylsheets for XML data, including ways of identifying XML components with\nXPath and of transforming XML with XSLT.\n

      \n

      \nI have included a number of links to the resources I used in the shownotes.\n

      \n\n

      Repository

      \n\n

      \nI have placed all of the scripts, their associated files, and HTML and PDF\nREADME files (extended shownotes) in a GitLab repository. This can be\nbrowsed at https://gitlab.com/davmo/magnatune-downloader\nor, if a copy is required it can be obtained with the command:\n

      \n\n
      \n  git clone https://gitlab.com/davmo/magnatune-downloader.git\n
      \n\n

      \nThis makes a local git repository containing a copy of all of the files in\nthe current directory.\n

      \n\n

      Note: The code was originally hosted on Gitorious\n(https://gitorious.org/magnatune-downloader), but with the demise of this\nservice it was moved to GitHub and the details above updated. Then since the\nMicrosoft takeover of GitHub, it has been moved to GitLab and the details\nupdated as needed.

      \n\n

      Scripts

      \n\n
        \n
      • update_albums: a Bash script to download a new version of the album\n catalogue, as a bzipped XML file, if it is different from the current\n version. It generates a summary of the catalogue for simple searching using\n XSLT.\n
      • report_albumsku: a Bash script to take a SKU code and look up the\n album details in the XML file.\n
      • get_album: a Bash script to download an album, cover images and artwork.\n It takes the SKU as an argument and uses it to make an URL for an XML\n file which points at all of the components, and this is downloaded (with\n authentication). The script then parses this file to get the necessary URLs\n for downloading. I only use the OGG format but it could easily collect any\n or all formats available from Magnatune. The script records the fact that\n this particular SKU code has been downloaded so that it isn't\n collected again in error. All downloaded files are given names beginning\n with the SKU code and are stored for the installation phase.\n
      • install_download: a Perl script which unpacks the downloaded zip file to\n its final destination then adds the cover images and artwork to the same\n place. I used Perl because it allowed me to query the zip file to determine\n the name of the directory that was going to be created.\n
      \n\n

      Further Developments

      \n\n

      \nI have added further scripts to this system since I created it. I have one that\nsynchronises the music files from my workstation to the server, and two that\ngive me a simple wish-list or queue functionality.\n

      \n

      \nSince I have a 200GB download limit per month on my broadband contract I try\nnot to download music too often and avoid contention with the rest of the\nfamily. My queueing system is used to keep a list of stuff I'd like to buy\nfrom Magnatune, and I simply feed the top element from the queue into my\ndownload script every week or so.\n

      \n

      \nIn the future I expect to be refining all of these scripts and making them\nless vulnerable to errors. For example, I have found a few cases where\nMagnatune's XML is not valid and this causes the xsltproc tool to fail.\nI'd like to be able to recover from such errors more elegantly than I'm doing\nnow.\n

      \n

      \nAt some point I may well be tempted to consolidate all of the current\nfunctions into a single Perl script.\n

      \n\n

      Disclaimer

      \n\n

      \nI have no connections to Magnatune other than being a contented customer.\n

      Last episode of Linux in the Shell discussed the use of the bc command to perform math on the command line. This episode continues in suit with a mathematical theme picking up from the last examples of converting between different number systems or units. While bc can help you convert between units if you know the formulas, there is another program which will do it all for your units. Chances are units is not installed by default but a simple check in your package manager should allow you to add units to your daily tool set.\n

      \n

      \nPlan to attend if you can.\n

      \n

      \nLinuxFest Northwest is an annual event produced by the Bellingham Linux Users Group, and volunteers from other northwest U.S. open source users groups. It is held on the campus of Bellingham Technical College (directions at the BTC website under ABOUT BTC). The Fest features Linux and open source experts and aficionados sharing their experience and enthusiasm with a wide variety of free and open source technologies.\n

      \n

      \nThis generally means that there will be a lot of smart people who come with something to share and a desire to learn. This is a low cost/high value event that's held on a weekend, so there are also folks who don't usually go to commercial conferences. All in all, it's a lot of fun with fresh faces on eager people.\n

      How better to explain it than by sending it out in Morse Code https://hackerpublicradio.org/eps.php?id=1343.

      \n

      \nIn this the first in a series exploring The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1)\n

      \n

      \n\nOSI model
      \nFrom Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/OSI_model\n      \n

      \n

      \n\nThe Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a prescription of characterizing and standardizing the functions of a communications system in terms of abstraction layers. Similar communication functions are grouped into logical layers. A layer serves the layer above it and is served by the layer below it.\n\n

      \n

      \n\nFor example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.\n\n

      \n

      \nIn today's show Ken starts off with a practical example of Layer One, the The Physical Layer, https://en.wikipedia.org/wiki/Physical_layer. Although we are limited to audio for the purposes of the show, the same techniques could and are used across the light spectrum.\n

      \nHowdy folks, this is FiftyOneFifty, and today I wanted to talk about my experiences installing the 64 bit version of Cinnarch net edition on a dual core notebook. Cinnarch of course is a relatively new Arch based distro running the Cinnamon fork of Gnome. I had previously installed Arch proper on this notebook, but when I rebooted to the hard drive, I lost the Ethernet connection. This is not uncommon, but there the notebook sat while until I had time to work the problem. I wanted to start using the notebook, and I'd heard good things about Cinnarch, so it seemed like a simple solution. I went into knowing Cinnarch was in alpha, so i shouldn't have been surprised when an update broke the system less then a week after the install, but that comes later in my story.\n

      Utilizing Maximum Space on a Cloned BTRFS Partition

      \n

      by FiftyOneFifty

      \n\n
        \n
      1. If you clone a disk to a disk, Clonezilla will increase (decrease) the size of each partition proportional to the relative size of the drives.\n\t
          \n\t
        1. I wanted to keep my / the same size and have no swap (new drive was SSD), so I did a partition to partition clone instead
          2. \n\t
        2. Created partitions on the new SSDs with a GParted Live CD, 12Gb root (Ext4) and the remainder for /home, (btrfs, because I planned to move to SSD from the start, and last summer only btrfs supported TRIM)
          3. \n\t
        \n
        2. \n
      2. After cloning /dev/sda1 to /dev/sdb1 and /dev/sda2 to /dev/sdb2 using Clonezilla, I inspected the new volumes with the GParted Live CD\n\t
          \n\t
        1. /dev/sdb2 had 40% inaccessible space, i.e., the usable space was the same size as the old /home volume
          2. \n\t
        2. GParted flagged the error and said I could correct it from the menu (Partition->Check) but btrfs doesn't support fsck, so it didn't work
          3. \n\t
        3. Tried shrinking the volume in GParted and re-expanding it to take up the free space, also didn't work.
          4. \n\t
        \n
        3. \n
      3. Discovered 'btrfs utility' and that it was supported by the GParted Live CD\n\t
          \n\t
        1. Make a mount point\n\t\t
            \n\t\t
          • sudo mkdir /media/btrfs
            • \n\t\t
          \n\t
          2. \n\t
        2. Mount the btrfs volume\n\t\t
            \n\t\t
          • sudo mount /dev/sdb2 /media/btrfs
            • \n\t\t
          \n\t
          3. \n\t
        3. Use btrfs utility to expand the btrfs file system to the maximum size of the volume\n\t\t
            \n\t\t
          • sudo btrfs filesystem resize max /media/btrfs
            • \n\t\t
          \n\t
          4. \n\t
        4. Unmount the btrfs volume\n\t\t
            \n\t\t
          • sudo umount /dev/sdb2
            • \n\t\t
          \n\t
          5. \n\t
        \n
        4. \n
      4. Rechecked /dev/sdb2 with GParted, I no longer had inaccessible space
        5. \n

      \nI got into Linux after listening to lots of podcasts during my work commute and I am one of those non-technical people listening that after lots of worrying finally installed Ubuntu and found out that it works pretty easily. A few month ago I got a raspberry pi and played with its Arch Linux version and very recently got the Acer C7 Chromebook and immediately put Chrubuntu on it, which is also how I am recording this.\n

      \nSo here is my strange problem. I currently have a Swiss-German keyboard layout at work, at the previous job I had an standard US keyboard and I am pretty sure that this chromebook has a UK keyboard. So I needed to find a really fast way to switch at first the UK keyboard layout to the Swissgerman layout and then also have a change to change to the US keyboard easily, because it happens ... you may believe it or not ... that some things I just know where they are in the US layout better than the Swiss layout and vice versa.\n

      \n

      \nThis is not really a problem if you stick with Unity. You go to System Settings, Keyboard Layout and add the relevant. Where are those System settings now? \n

      \n

      \nsetxkbmap is the command. In /usr/share/X11/xkb/rules I found all the layouts (ch for Swiss and us for American layout). I added the option to toggle between ch and us by click both shift keys. So the full command as alias is Swiss='setxkbmap -option 'grp:shifts_toggle' 'ch,us''. To not write the entire thing you can add this as a alias in .bashrc or probably put somewhere in a startup file, so you don't have to worry about it.\n

      \n

      \nFurther configurations and installations:\n

      \n\n
        \n
      • To enable the 2nd screen use command: xrandr --output HDMI1 --auto --right-of LVDS1\n
        • \n
      • Change hostname by editing nano /etc/hostname (by default it is Chrubuntu)\n
        • \n
      • Install cmatrix just for fun\n
        • \n
      • Installations: Desktop Environment openbox, lxde, i3 just to play around - Terminator as terminal emulation - ranger as file manager - s3cmd for offsite backup, although dropbox and spideroak work too (s3cmd works also on raspberry pi) - encryption with encfs and truecrypt\n

      A final note - the app version that I mention in the show was upgraded\nliterally about 5 minutes after I finished editing and started to prepare this\nshow for upload. (And, yes, I'm using \"literally\" correctly - I mean I finished\nexporting the file from audacity, went to check Google+, and within 300 seconds\nsomeone was mentioning that a new version was out).

      \nNido is joined by dude-man, Epicanis, and artv61 to \ndiscuss how one could or should define \"Hacker\" and \"Hacking\", particularly in \nreference to the \"Hackers\" that Hacker Public Radio episodes are intended to be\n\"of interest to\". Unfortunately, all participants seemed to be largely in\nagreement with each other, so there isn't enough contention to make the \ndiscussion dramatic. Listeners may find the discussion insightful anyway,\nand we do come up with some suggestions and ultimately encourage everyone to\nbe a lot more public about using the words \"hacker\" and \"hacking\" as\nmuch as possible outside the context of criminal and computer-programming\nactivity until outdated dictionaries finally update their definitions.

      \nHPR Episode: Doomsday Perpetual Calendar Method\n\nWhat is it?  https://en.wikipedia.org/wiki/Doomsday_rule\n  (due to John H. Conway, a mathematician born in Liverpool)\n\n  * He's done other research that hackers might like to check out.\n  * Look up the \"Game of Life\" and \"cellular automata\".\n  * There may be episodes on these topics, but those should come\n      with visualization software.\n\nJohn H. Conway\n  https://en.wikipedia.org/wiki/John_Horton_Conway\n\nGame of Life\n  https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life\n\n\nDoomsday Rule lets you find the day of the week for any date\n  * Dates in history, in immediate past or in future are all good.\n  * Works for both the Gregorian and Julian calendar.\n    - I'll only be looking at Gregorian dates for now.\n    - Method should work well for dates from 1800 onward.\n    - If dates for non-Gregorian calendars are converted to their\n        (extrapolated) Gregorian equivalents, this method works.\n\nWikipedia entry (includes recent optimization):\n  https://en.wikipedia.org/wiki/Doomsday_algorithm\n\n\nWhy do this?  It came up in Episode Zero of my \"N Days\" show on\ncalendar counting, where I used it without explanation.\n\n  https://hackerpublicradio.org/eps.php?id=1143\n\n\nDemos: Check these answers at www.day-calculator.com\n  * Some listeners may now adjourn to the latest Linux Outlaws episode.\n\n\nMethod: Get Century Anchor Day, calculate offset for the year to find\n   Doomsday's reference location for current year, find closest\n   reference date to target date, and count off to the answer.\n\na) Isaac Newton's date of birth:\n   - 25 December 1642 - 1600's Tuesday.\n     Year 42 = 3*12 + 6 and (6/4) = 1.\n     Hence 3 + 6 + 1 = 10 for an offset of 3.\n     Tuesday + 3 = Friday.  12/12 is Friday, so 12/26 is Friday\n     Newton was born 12/25, so that was a Thursday\n\nb) My grandfather's date of birth:\n   - 20 January 1898 - 1800's anchor is Friday.\n     Year 98 = 8*12 + 2, (2/4) = 0.\n     So 8 + 2 + 0 = 10 gives an offset of 3.\n\n   - 1898 wasn't a leap year, so 10 January was Monday\n   - That means 17 January was a Monday, too.\n   - So 20 January 1898 was a Thursday.\n\nc) A wedding anniversary that I like to remember: 15 May 2000\n   - 2000 has anchor day on Tuesday, and no offset.\n   - Rule: \"I work 9 to 5 at 7-11\", so 9 May (16 May) are on Tuesday.\n   - 15 May 2000 was a Monday.  True.  'Twas the day after Mother's Day.\n\nd) My parent's wedding day: 19 May 1957\n   - 1900 has anchor day Wednesday.  57 = 4*12 + 9 and (9/4) = 2.\n   - So 4 + 9 + 2 = 15 or an offset of 1.\n   - 9 May is Thursday, as is 16 May.  The 19th is 3 days later.\n   - So 19 May 1957 was a Sunday.\n\n\nPlan: I'm going to reveal the magic behind this, and introduce some\nmental shortcuts to help you learn to do this in your head.\n\nIf you can master the 12's row in your times tables up to 8 times 12,\nand the 4's row up the 20s or 30s, and you can tell time on a 12-hour\nclock, you should be able to do this.\n\nWe're not in school, so paper and pencil to track the numbers, and\nfinger-counting offsets to days of the week are all allowed.\n\n\nExplanation:\n1. Certain memorable dates fall on the same day of the week as\n   \"Doomsday\" = last day of February, whatever that is.\n\n2. Dates recycle every 400 years, and Doomsday Anchor dates by Century\n   are 1600: Tuesday, 1700: Sunday, 1800: Friday, 1900: Wednesday.\n\n3. That's enough, but to simplify mental math notice 12-year cycles.\n   - Every completed 12 years pushes the days of the week ahead by +1\n   - Each year within the current incomplete cycle adds +1\n   - Each leap year in current cycle adds +1 (including current year)\n\n4. Doomsday dates are:\n   a. January 10 and Doomsday (last day of February)\n\n   b. Odd months: Add +4 through July, then subtract 4.\n      7 March, 9 May, 11 July\n      5 September, 7 November\n\n   c. Even months are reflexive: 4/4, 6/6, 8/8, 10/10, 12/12\n\n\nSee the attached spreadsheets for examples and annotated calculations.\n\n - LibreOffice Calc: 229-Charles-in-NJ-Doomsday-Rule-v1.ods\n\n - Excel 5/95 'xls' for LibreOffice or Gnumeric:\n     229-Charles-in-NJ-Doomsday-Rule.xls\n\n - Gnumeric: 229-Charles-in-NJ-Doomsday-Rule-v1.gnumeric\n\n\nBonus Content:\n - Excel VBA module: 229-Charles-in-NJ-Doomsday-Rule.vbaxl.bas\n     * Import the .bas module\n     * Input is an Excel \"Date\" object\n     * Very proprietary formats and code, but some people use it.\n\n - Python:  doomsday.py\n     * Contains two functions:  Each returns a string value for the day\n          of the week, e.g., \"Sunday\"\n\n       dayOfWeek(year, month, day): Doomsday is last day of February,\n          and the (month, day) are converted to relative ordinal dates.\n          For leap years, we have to push both Doomsday and any target\n          date after 28 February up by one for the leap day.\n\n       dayOfWeek2(year, month, day): Doomsday date anchors are computed\n           for each month, so leap years require adjustments to the\n           anchors for January and February to account for the shift\n           in the February ending date.  Later months are fine.\n\n - Script for GNU 'bc': doomsday.bc is a bc 'port' of the Python code\n     * Differences: Return value is a number from 0-6 that represents\n         the day of the week by its relative position.\n\n       0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday,\n       4 = Thursday, 5 = Friday, 6 = Saturday\n\n     * In a shell, run 'bc' with the filename as an argument:\n       catintp@Derringer:~$  bc doomsday.bc\n\n       - This loads the two functions in the file.  You can invoke them\n           within 'bc' like any other function:\n\n       dayofweek(1981, 5, 15)\n       dayofweek2(1642, 12, 25)\n       dayofweek(2013, 11, 22)\n       dayofweek2(2059, 5, 19)\n\n - Alternate Script for GNU 'bc': doomsday2.bc\n     * Return value is still a number from 0-6 that represents\n         the day of the week by its relative position.\n\n     * Uses a side effect to print a human-friendly answer.\n\n     * English only, but localisation should be easy.\n

      \nI would like to suggest the following amendments to the scheduling\nrules detailed below in ALL CAPS bellow:\n\n++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\nhttps://hackerpublicradio.org/calendar.php#normal_priority\nWe now release shows based on when the hosts last had a show aired.\nThis brings new hosts and returning hosts to the top of the queue to\nencourage their efforts, and it also spreads out shows submitted in\nbatches and gives a wider variety of hosts. Once a host is determined,\nthe first show uploaded by that host is released. If you wish your\nshows to be released in a particular order then make sure you make that\nobvious in the title and by emailing admin@hackerpublicradio.org.\nYou can swap the order of the shows but it involves additional effort\nand is frowned upon :).\nWHERE POSSIBLE WE WILL NOT RELEASE SHOWS FROM THE SAME HOST IN ANY ONE\nWEEK.\n++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n\nhttps://hackerpublicradio.org/calendar.php#synicated_shows\nSyndicated Shows\nWe will continue to promote new podcasts and other creative commons\nmaterial but due to a lack of slots, we are only releasing material\ncreated exclusively for HPR. If there is a piece of creative commons\ncontent that you would like to promote, then feel free to record a\nregular show where you introduce the content and explain why it is\nimportant and providing links to where we can get more information.\nTHESE SHOWS CAN BE RELEASED EITHER UNDER YOUR OWN NAME OR UNDER\nTHE GENERIC HOST CALLED \"VARIOUS CREATIVE COMMONS WORKS\" (HOSTID 158)  \n++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n\nThe amendment \"WHERE POSSIBLE WE WILL NOT RELEASE SHOWS FROM THE SAME\nHOST IN ANY ONE WEEK.\" had been included prior to the changes in\nJanuary, but I would like to put it back.\n\nThe amendment \"THESE SHOWS WILL CAN BE RELEASED EITHER UNDER YOUR\nOWN NAME OR UNDER THE GENERIC HOST CALLED \"VARIOUS CREATIVE COMMONS\nWORKS\" was discussed in the mail list under the title of \"Various\nCreative Commons Works\" but the discussions got derailed. \n\nPlease keep discussion to these two points only. \n\nAs always Silence, or no comment is assumed to be approval.\n\nKen.\n\nAlso the addition of the following text to the Scheduling Rules: \nPlease be aware that we cannot predict when your show will be out, but \nsooner of later it will be released. Sometimes a new host will jump to \nthe top of the queue, while other hosts seem to be waiting a long time. \nThis is because all the shows at HPR are scheduled according to the \nScheduling Guidelines, which apply to everyone without exception.\n\n

      In looking at the distinction between free of charge and free as in freedom, some interesting issues emerge. I argue that free of charge is often not what we should be looking for if we want good software options. But because I like going the long way around behind the barn to get anywhere, I start off in the Music business.

      \n

      Build vs Buy

      \n

      Do you have the interest and time to\nresearch and build a desktop computer?

      \n

      You probably won't save a lot of money,\nbut with all the research you may get better quality parts.

      \n

      You will know exactly what's in your\nsystem should issues or questions ever arise.

      \n


      \n

      \n

      Gather requirements

      \n

      Define the purpose of the system \n

      \n

      Use: gaming,\nvideo/photo processing, web browsing/documents

      \n

      Applications\nshould drive most of your hardware decisions.

      \n

      Data protection: \nhow much data, how resilient (on-site mirroring, RAID vs. off-site)

      \n

      Power protection: \nsurge suppression, UPS

      \n

      Physical\nprotection: keyed case lock (disassembly prevention), cable anchor

      \n


      \n

      \n

      Define a budget \n

      \n

      Decide what are\nyou willing to spend (max, target, min)

      \n

        Check\noff-the-shelf models to get the going price points

      \n

      Understand there\nare trade-offs and if everything is needed at once

      \n

      Adding\ncapabilities later can help with sticker shock

      \n

      If you have time,\nbuy components when prices dip

      \n

      Be careful about\nreturn policies...some 30 or 90 days

      \n


      \n

      \n

      Learn about current technology &\nprices

      \n

      Core: CPU,\nmemory, motherboard, graphics controller, power supply

      \n

      Storage: solid\nstate drives, rotating hard drives, removable media (DVD, USB)

      \n

      Auxiliary: audio,\nmonitor, power protection, web cam, printer/scanner, backup drive

      \n

      Interfaces: SATA,\nIDE, DDR2, DDR3, PCI, PCI-e, USB, eSATA

      \n

      Determine\napproximate price range

      \n

      Where to research\nthis stuff: Wikipedia, Tom's Hardware, Anandtech, Specs on vendor web sites

      \n

      Where to shop: NewEgg.com,\nAmazon.com, Dell.com

      \n


      \n

      \n

      Understand compatibility

      \n

      Hardware-Hardware\ncompatibility

      \n

      \tCheck qualified\nhardware list (QHL) on CPU/memory/motherboard

      \n

      \tAlso known as CPU\nsupport list, memory support list, qualified vendor list, etc.

      \n

      \tIf you can stick\nto the QHL parts, h/w compatibility is more assured

      \n

      Hardware-Operating\nSystem compatibility \n

      \n

      Drivers, either\nbuilt into the OS or from vendor web site

      \n

      Pay attention to\n32-bit vs. 64-bit in both operating systems and drivers

      \n

      Operating\nSystem-Application compatibility

      \n

      \tI'm not going to\naddress this, but it is something to research and understand.

      \n


      \n

      \n

      Define what components you need

      \n

      You will need the\ncore and storage components.

      \n


      \n

      \n

      If you have\ncomponents (particularly auxiliary components) from a previous\nsystem, you may find you can use them with the new system. Speakers,\nprinter, and monitors are all prime candidates.

      \n


      \n

      \n

      Steps

      \n
        \n\t
      1. CPU
        \n
      \n
        \n\t

      • Decide on CPU brand (typically\n\tIntel or AMD)

        \n\t

      • Decide on CPU model, which is\n\tdictated by your needs and budget

        \n\t

      • CPU will dictate motherboard\n\tsocket type

        \n\t

      • Be sure to buy CPU in box set so\n\tit includes CPU fan & heat-sink. Otherwise, you'll need to\n\tfigure out the thermal dissipation needs and physical dimension\n\tlimitations of the case in order to select an appropriate 3rd party\n\tCPU fan & heat-sink. This can involve liquid cooling solutions.\n\t I'm not covering thermal solutions in detail here.

        \n
      \n
        \n\t
      1. Motherboard
        \n
      \n
        \n\t

      • Narrow search to motherboards with\n\tsocket type that matches CPU.

        \n\t

      • Decide on motherboard form factor\n\t(ATX, Mini-ATX, Micro-ATX, Mini-ITX, etc.). See Wikipedia.

        \n\t

      • Video on-board or discrete. \n\t

        \n
          \n\t

        • If on-board, check if it has\n\tdedicated memory or borrows memory from main system. If it borrows\n\tfrom the main system, you may want to increase your memory size. \n\tRecommend using discrete if 3-D requirements exist. You can go\n\tdiscrete later, but you'll have wasted money on the motherboard.

          \n\t

        • If discrete, ensure motherboard\n\thas enough high-end PCI-e slots for your needs. \n\t

          \n
        \n
      \n
        \n\t

      • Audio on-board, discrete or\n\texternal.

        \n
          \n\t

        • If on-board, check motherboard has\n\tsuitable output ports for your needs.

          \n\t

        • If discrete, ensure motherboard\n\thas a slot for the audio card.

          \n
        \n
          \n\t

        • If external audio system will be\n\tused, make sure motherboard has ports to support it.

          \n\t

        • WiFi / Blue Tooth

          \n\t

          While a few motherboards have these,\n\tthey are generally considered inferior for connectivity and security\n\ton a non-mobile device like a desktop. It's also easy to add a card\n\tor USB device to obtain them. Also, when integrated on the\n\tmotherboard, they are harder to upgrade later.

          \n
        \n
      \n
        \n\t

      • Outputs ports meet your needs\n\t(PS2, Parallel, Serial COM, USB, eSATA, S/PDIF, HDMI, Ethernet,\n\tetc.)

        \n\t

      • At this point, you search should\n\tbe fairly narrow – compare prices, read reviews and compare\n\tratings. \n\t

        \n\t

      • Decide on motherboard vendor and\n\tmodel

        \n
      \n
        \n\t
      1. Memory
        \n
      \n
        \n\t

      • Based on motherboard, find\n\tmatching memory type. DDR2 and DDR3 are the common types. \n\t

        \n\t

        There are 5 memory properties: \n\t

        \n
          \n\t

        1. DDR revision (currently they\n\tinclude DDR, DDR2, and DDR3)

          \n\t

        2. Chip Classification (like\n\tDDR2-1333) where the number (1333) is the maximum clock speed (in\n\tMHz) the memory chips support, which is halved for real clock speed\n\t(666.5MHz).

          \n\t

        3. Module Classification (like\n\tPC3-10666) where the number (10666) is the maximum transfer rate (in\n\tMB/s). This is typically 8 times the first memory chip\n\tclassification clock speed, so DDR400 transfers data at 3,200 MB/s. \n\t\t

          \n\t

        4. Timing (like 7-8-8-24) measures\n\tthe time the memory chip delays doing something internally.

          \n\t

        5. Voltage (like 1.5v) \n\t

          \n
        \n
      \n
        \n\t

      • Note the memory properties are\n\tmaximums. Actual rates will be lower based on the motherboard. \n\tMatch the first 3 properties – DDR revision, chip classification\n\tand module classification. DDR revision must match. If you can't\n\tget an exact match on Chip and Module classifications, make sure the\n\tmemory module is faster (higher numbers) than the motherboard.

        \n\t

      • If you plan to over-clock, you'll\n\tneed to pay attention to all 5 properties, but I'm not going to\n\tcover over-clocking.

        \n\t

      • For more assurance, buy memory\n\tthat's on the motherboard maker's certified list.

        \n\t

      • Recommend buying memory in higher\n\tcapacities per module for future expansion. If you have 4 memory\n\tmodule slots which can accept 1G, 2G, and 4G modules, opt for the 4G\n\tmodules.

        \n\t

      • Recommend that all memory modules\n\tbe the same size, optimally the same brand/model if possible.

        \n
      \n
        \n\t
      1. Video Card
        \n
      \n
        \n\t

      • If using on-board video\n\tcontroller, you've already decided this.

        \n\t

      • If using discrete video card,\n\tnarrow search to available motherboard slots. \n\t

        \n\t

        For example, if you only have one\n\tPCI-e 16x slot, narrow search to video cards that can use that slot.\n\t Don't worry about AMD's CrossfireX or NVIDIA's SLI card linking\n\tbecause you don't have two slots. \n\t

        \n\t

      • If you buy a high-end discrete\n\tcard or cards, be sure to check the video card vendor's recommended\n\tpower supply wattage and required power connector. These cards\n\toften require a separate power connector from the power supply.

        \n
      \n
        \n\t
      1. Internal Storage
        \n
      \n
        \n\t

      • By internal\n\tstorage, I mean storage devices that will be housed inside the\n\tcomputer case.

        \n\t

      • Most\n\tmotherboards come with an on-board storage controller, typically\n\tSATA 2. Some have an IDE controller for legacy support. Server\n\tmotherboards may have some version of SCSI or SAS (serial attached\n\tstorage) controllers.

        \n\t

      • These\n\ton-board controllers are configured from within the BIOS or UEFI. \n\tDepending on the motherboard's south bridge chipset, it may support\n\ta few RAID levels, usually levels 0 (striping) and 1 (mirroring).

        \n\t

      • Storage\n\tdevices come in different physical sizes which require different\n\tsized bays - 5.25 inch, 3.5 inch, 2.5 inch, and 1.8 inch. These\n\trefer the size of the storage medium, not the actual bay size. The\n\t5.25 inch bays come in half-height versions, which are the standard\n\tfor CD and DVD drives in todays' computers. The 3.5 inch bays are\n\tusually used for floppy or Zip drives...more legacy equipment. See\n\tWikipedia.

        \n\t

      • Storage\n\tdevices can vary significantly in storage capacity. Often, the\n\tlarger the storage capacity, the higher the latency in storing and\n\tretrieving data. Cache on-board the disk can mitigate this latency,\n\tso larger cache sizes are preferred particularly for large capacity\n\tdrives. Cache sizes currently include 8MB, 16MB, 32MB and 64MB.

        \n\t

      • With rotating\n\tmagnetic disks, the speed at which they rotate can also mitigate\n\tthis latency. Rotation speeds include 5400 rpm, 7200 rpm, and 10000\n\trpm and 15000 rpm with each step in speed requiring more power and\n\tgiving off more heat.

        \n\t

      • If you need\n\tmore than 2 or 3 drives, you'll need to ensure your case has\n\tadequate physical space for them and that your power supply is sized\n\tappropriately.

        \n
      \n


      \n

      \n
        \n\t
      1. Case & Power Supply
        \n
      \n
        \n\t

      • Some cases are bundled with a\n\tpower supply, which might work great for average to low-end system\n\tconfigurations.

        \n\t

      • Based on motherboard form factor\n\tand internal storage requirements, pick out a computer case. \n\t

        \n\t

      • Case features to consider:

        \n\n
          \n\t

        1. Power supply location is always\n\tin rear, but can be on top or bottom of a tower configuration. If\n\tthe computer will sit on the floor, having the power supply on the\n\tbottom might turn it into a dust bunny haven.

          \n\t

        2. Number and type of storage drive\n\tbays.

          \n\t

        3. Removable and/or washable dust\n\tfilters.

          \n\t

        4. Lighting kits

          \n\t

        5. Front panel ports and static\n\tsuppression

          \n
        \n
      \n
        \n\t

      • The number and size of fans is\n\tlimited by the case design. Typically a case will come with one\n\trear fan, but most offer front, side, or top vents where fans can be\n\tmounted. Fan sizes range from 25mm to 250mm, with popular sizes at\n\t80mm, 92mm, 120mm and 140mm.

        \n\t

      • Make sure power supply is sized\n\tcorrectly:

        \n\n
          \n\t

        1. Physical dimensions fits in case\n\t(beware “slim” power supplies for smaller form factor cases).

          \n\t

        2. Wattage output, which is driven by\n\tvideo cards and number of internal storage devices.

          \n\t

        3. Connectors required by the\n\tmotherboard, CPU fan, case fans, video card and internal storage\n\tdevices.

          \n
        \n
      \n
        \n\t

      • Without a discrete video card and\n\t2-3 internal storage devices, 300-400 Watts power supplies are\n\ttypical. If getting a discrete video card, check on its power\n\trequirements.

        \n\t

      • Power supplies also have\n\tefficiency ratings under the "80 PLUS" certifications, which\n\tspan from vanilla 80 PLUS, Bronze, Silver, Gold and Platinum. See\n\tWikipedia for more info.

      \nIn this episode I discuss my experience building a Recumbent Bicycle from donor bikes. A couple of things I forgot to mention while recording the podcast. First of all I had to use tandem bicycle cables for the brakes and the rear derailleur because they had to be very long. I also forgot to talk about the time when I was in a panic that the rear triangle was a bit out of alignment with the front, such that it would make the bike turn a little bit to the left by default. I called Andrew Carson and asked him if there was anything I could do to fix it and his solution was just awesome. What he told me to do was to put a spare hub in the rear triangle to keep the seat- and chain stays from collapsing together, lay the frame on the ground with the front end propped up on a step or something, and then just stand on it, jumping up and down slightly on it if necessary until I could feel it bend back a little bit. This actually worked! It straightened the frame right out. :) Finally, the total cost for this project was under $300. The most expensive single part of it by far was the powder coat, which cost $120. Here are links to resources mentioned in the podcast or simply of general interest.

      Editor’s Note 2020-01-02

      \n

      The notes for this episode have been reformatted, particularly the long-form notes. This was done to make them more readable. Also, the original Git repository has been changed from Gitorious to GitLab.
      \nIn 2019 an iCalendar file was placed on the HPR server at https://hackerpublicradio.org/HPR_Community_News_schedule.ics which you can use in your own calendar application. The file contains the recording times of 12 months of Community News shows and is updated monthly.

      \n

      The Problem

      \n

      Back in 2012 Ken Fallon tried to use Google Calendar to set up an event for the recording of the monthly Community News shows on HPR. He wanted to set these on the Saturday before the first Monday of the month. Surprisingly he didn’t find a way to do this and ended up deleting the attempt.

      \n

      I looked at the calendaring application I use: Thunderbird with the Lightning calendar plugin, to see if I could manage it. I also couldn’t find a way.

      \n

      This episode documents my journey to find a way to make the calendar entries we need.

But one thing he has rebelled against is camping (ok also Steak Tartare aka 'American Fillet' aka raw cow). That most Dutch of traditions, where the family head off to some deserted field, be it by the sea, in a forest, or on the polder, one thing is sure, it will be damp, wet, mosquito ridden, dark too late and bright too early, and wet - optionally cold and hot. In short hell. Of course that's his personal opinion. \n

One way I do that is to try and make myself useful, and one useful thing that I know is how to light and keep a small fire going. No one else ever seems to want to do it, and it's fun if you do it right. Admittedly there isn't much to it, but that just makes it all that much easier to learn. It isn't quite as intuitive as you might think if you've never done it, especially if it's a little damp out. Use tinder (paper, dried grass, cotton balls, etc...) to get the flame going, light your kindling (small twigs, pinecones, split sticks) over the tinder, and increase the size of your kindling until you have a good pile of coals that can sustain the burning of split logs. Keep your logs and sticks as parallel as you can, make sure air can flow freely through your burning pile of wood and don't let your coals spread too thin. If you're good, you should be able to get a fire going with just a single match and no accelerants (which are usually illegal anyway). If you're really good, you might even be able to do it with just a spark.\n

      This program is a special panel discussion episode of, This Week in Energy (TWiE), where co-hosts Kirsten & Bob define the concept of Energy Democracy and hacking the traditional central-station monopoly electric utility business model.

      \n

      There's an energy transition (or \"energiewende\" in German) underway in the energy space where the 19th and 20th century central-station monopoly utility business model is breaking down (or getting hacked) and ownership of electric generation capacity is transferring to individuals, co-ops, and so forth.

      \n

      This is due in large part to an entropy effect because \"the ubiquitous nature of renewable energy argues for a decentralist energy approach.\" But, also, public policy can either help the energy transition move faster, or it can slow it down.

      \n

      Thus an emerging global battle is brewing and it's very similar to the disruptions that have been taking place in the telecom sector due to advancements in IT and the advent of the Internet over the past couple of decades.

      How I Manage Contacts

      \n\n

      About a year ago I decided to try to clean up my contacts.

      \n\n

      The problem: CRUFT!

      \n\n
        \n
      • Importing, exporting re-importing in different accounts and in different email clients and several computers etc over span of ~10 years.
        • \n
      • 1200+ gmail contacts
        • \n
      • Many duplicates
        • \n
      \n\n

      What I wanted:

      \n\n
        \n
      • 1 set of contacts across platforms with single source file from which all\nothers are generated
        • \n
      • plain-text format, easy to use w/scripting & text editor
        • \n
      • No duplicates
        • \n
      • no cruft
        • \n
      • easy to maintain
        • \n
      • easy to import/export in T-bird, ownCloud
        • \n
      • sync with phone
        • \n
      \n\n

      Steps to Success:

      \n\n
        \n
      1. Turn off Gmail default setting that saves every incoming email address in your address book
        2. \n
      2. Deleted all extraneous contacts (went from ~1200 down to about 400)
        3. \n
      3. Tedious part here: compare duplicates, consolidate info
        4. \n
      4. Decide on source-file format
        5. \n
      5. T-bird = LDIF
        6. \n
      6. OwnCloud = vCard
        7. \n
      7. LDIF wins b/c found script to convert to vCard, but not good script for other direction
        8. \n
      8. Convert all disparate contacts lists to LDIF, begin consolidating into one file
        9. \n
      9. LDIF ready? Import to T-bird
        10. \n
      10. Perl script to convert LDIF to vCard –> import to ownCloud
        11. \n
      11. CardDAV-sync to sync from o.c. to phone
        12. \n
      12. Bash script to create new LDIF entries, convert to vcf, add to master file easily
        13. \n
      \n\n

      Wishlist

      \n\n
        \n
      1. Make t-bird sync w/owncloud (t-bird SOGO extension broken)
        2. \n
      2. CLI API to update owncloud contacts via a script instead of having to use the web interface
        3. \n
      \n\n

      MOLLE

      \n

      From Wikipedia, the free encyclopedia

      \n

      \nMOLLE (pronounced molly, as in the female name) is an acronym for Modular Lightweight Load-carrying Equipment. It is used to define the current generation of load-bearing equipment and rucksacks utilized by a number of NATO armed forces, especially the British Army and the United States Army. The system's modularity is derived from the use of PALS webbing as rows of heavy-duty nylon stitched onto the vest to allow for attachment of various MOLLE-compatible pouches and accessories. \n

      2 History of the language

      \n
        \n

      • developed by Ken Thompson and Dennis Ritchie between 1969 and\n1973 at AT&T Bell Labs.

        • \n

      • The origin of C is closely tied to the development of the Unix\noperating system, originally implemented in assembly language on a PDP-7\nby Ritchie and Thompson, incorporating several ideas from colleagues.\nEventually they decided to port the operating system to a PDP-11. B’s\ninability to take advantage of some of the PDP-11’s features, notably\nbyte addressability, led to the development of an early version of\nC.

        • \n
      \n

      3 Uses

      \n

      C is often used for “system programming”, including implementing\noperating systems and embedded system applications, due to a combination\nof desirable characteristics such as code portability and efficiency,\nability to access specific hardware addresses, ability to pun types to\nmatch externally imposed data access requirements, and low run-time\ndemand on system resources. C can also be used for website programming\nusing CGI as a “gateway” for information between the Web application,\nthe server, and the browser. Some reasons for choosing C over\ninterpreted languages are its speed, stability, and near-universal\navailability.

      \n

      One consequence of C’s wide availability and efficiency is that\ncompilers, libraries, and interpreters of other programming languages\nare often implemented in C. The primary implementations of Python\n(CPython), Perl 5, and PHP are all written in C.

      \n

      Due to its thin layer of abstraction and low overhead, C allows\nefficient implementations of algorithms and data structures, which is\nuseful for programs that perform a lot of computations.

      \n

      C is sometimes used as an intermediate language by implementations of\nother languages. This approach may be used for portability or\nconvenience; by using C as an intermediate language, it is not necessary\nto develop machine-specific code generators.

      \n

      C has also been widely used to implement end-user applications, but\nmuch of that development has shifted to newer languages.

      \n

      4 Characteristics of the\nlanguage

      \n
        \n
      • imperative, compiled, static, weakly typed
        • \n
      • structured programming\n
          \n
        • Uses functions but it is not functional, but rather procedural
          • \n
        • control flow if/else, for, while
          • \n
        • curly braces, semi-colons
          • \n
        • \n
      • all parameters are passed by value and references are simulated\nusing pointers
        • \n
      • A program is a function called main
        • \n
      \n

      6 Hello World

      \n
      #include <stdio.h>\n\nint main(void) {\n    printf("hello, world\\n");\n    return 0;\n}
      \n

      7 How to make a C program

      \n
        \n
      • Write your main function into a file called myprogram.c
        • \n
      • compile your program\n
          \n
        • gcc -o myprogram myprogram.c
          • \n
        • \n
      • if you use other libraries than C’s standard library, you will need\nto use a linker, like ld
        • \n
      \n

      Examples taken from An\nIntroduction to GCC by Brian J. Gough, foreword by Richard M.\nStallman

      \n

      The classic example program for the C language is Hello World. Here\nis the source code for our version of the program:

      \n
      #include <stdio.h>\n\nint main (void) { printf ("Hello, world!\\n"); return 0; }
      \n

      We will assume that the source code is stored in a file called\n'hello.c'.

      \n

      To compile the file 'hello.c' with gcc, use\nthe following command:

      \n
      $ gcc -Wall hello.c -o hello
      \n

      To run the program, type the path name of the executable like\nthis:

      \n
      $ ./hello\nHello, world!
      \n

      8 Pointers!

      \n

      C supports the use of pointers, a type of reference that records the\naddress or location of an object or function in memory. Pointers can be\ndereferenced to access data stored at the address pointed to, or to\ninvoke a pointed-to function. Pointers can be manipulated using\nassignment or pointer arithmetic. The run-time representation of a\npointer value is typically a raw memory address (perhaps augmented by an\noffset-within-word field), but since a pointer’s type includes the type\nof the thing pointed to, expressions including pointers can be\ntype-checked at compile time.

      \n

      9 The standard library

      \n
        \n
      • just use man!
        • \n
      \n

      On Unix-like systems, the authoritative documentation of the actually\nimplemented API is provided in form of man pages. On most systems, man\npages on standard library functions are in section 3; section 7 may\ncontain some more generic pages on underlying concepts (e.g. man 7\nmath_error in Linux).

      \n
      apropos sqrt | grep \\(3\\)\n\nman 3 sqrt\n\nman 3 qsort history
      \n

      In the 21st century, the Rosetta Project produced a disk containing 13,000 pages of information about more than 1,500 languages spoken on Earth today and in the recent past.

      \n

      \nOHM2013. Observe, Hack, Make. A five day outdoor international camping festival for hackers and makers, and those with an inquisitive mind. On 31st July 2013, 3000 of those minds will descend upon on an unassuming patch of land, at the Geestmerambacht festival grounds, 30km north of Amsterdam.\n

      \n\n

      \nIt is a four year tradition in The Netherlands to hold such an event. In the spirit of WTH, HIP and HAR the latest edition, OHM2013, is a non-commercial community run event. The event happens thanks to the volunteers, all 3000 of them. They will run the network, help people around the site, give talks, hold workshops and be excellent to one another.\n

      \n\n

      The target audience includes free-thinkers, philosophers, activists, geeks, scientists, artists, creative minds and a whole bunch of people interested in lots of interesting stuff.\n

      \n

      Lock Picking

      \n

      \nFirst port of call is a lock picking in a tent. Although lacking modern conveniences like, for example, doors, Nigel and the team has assembled a selection of locks for all levels.

      Rainbow Island

      \n

      \nNext stop \"Rainbow island\" for a chat with Johan, Brenn, Stitch and Joob.
      \nFrom https://ohm2013.org/site/2013/06/07/project-rainbow-island-2500-sqm-of-old-skoolynessism/\n

      \n\n

      \nRainbow Island is possibly the most modest project you'll see at OHM2013. Obviously, in this context, possibly means absolutely, and modest means insane.\n

      \n

      \nThe 2,500 sqm island on field R will be adorned by an immense castle-like structure, with towers that reach five meters into the air. In daylight, you'll see just a marble-white castle. But at night, it turns into an oasis, nay, orgasm of colours, video projections, smoke, and laser-beams.\n

      \n\n

      \nInside the castle, several tents will be raised, containing all kinds of art and entertainment.\n

      \n\n

      \nThe first tent will host vintage pinball and arcade machines. But these are not just for mindless consumerism! There will be a large pinball-repair station, where these old machines can get the TLC they so often need. Bring your multi-meter, spare parts, screwdrivers, and hack away! There will be a number of machines eligible for improvement.\n

      \n\n

      \nThe second pair of tents will contain the complete collection of Awesome Retro, a group of retro-gaming enthusiasts who collect everything regarding gaming, as long as it's over a decade old. You'll find classics like Super Mario Kart and Bomberman, the first editions of Pong and Pac-Man, and a lot of other blasts from the past, which will wrap you like the warm blankets that they are. Besides that, you'll find a fine collection of ultra-high-end Personal Computers, but to year-2000 standards, of course. A game of Quake 1 multiplayer, anyone?\n

      \n\n

      A small and informal stage surrounded by sofas will also be available for competitions and presentations. In the time in between events, this “living room” is free to use as a cosy lounge. Because what better way to enjoy gaming than from a sofa, with friends, whilst eating crisps?\n

      \n

      \n\"Rainbow\n

      \n

      And that is all, you think? Think again, because this is Rainbow Island, where the word “boundary” got scratched from the dictionary!\n

      \n

      \nFirst of all, numerous smaller tents will be put up within the walls of the castle, consisting of the essentials of multi-player retro-gaming: comfy four-seater sofa, game console, great 4-player game, four controllers, a TV… and projector! Yes, the games will be projected on the castle walls, which are semi-transparent, so even people on the outside will be able to enjoy the competitions.\n

      \n

      \nNext, the interiors of the four castle towers are available for all kinds of arts and other projects. These towers are 4 by 4 meters wide, and can be entered at the ground level. You may claim these for your own projects!\n

      \n

      \nOther highlights which are in the process of being perceived –or otherwise prepared– are a life-size model of a CRAY-1 supercomputer, Operation Oversight (a master-control room putting you in the driver's seat of the world's super powers), and of course the results of the Dance Dissect Repurpose competition.\n

      \n

      \nNext we have a chat with Jeff POINCARE who was building a seat shaped like a Cray 1.
      \nCray-1
      \nFrom Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/Cray-1\nThe Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. The first Cray-1 system was installed at Los Alamos National Laboratory in 1976 and it went on to become one of the best known and most successful supercomputers in history. The Cray-1's architect was Seymour Cray, the chief engineer was Cray Research co-founder Lester Davis.\n

      BruCON

      \n

      \nFrom: https://2013.brucon.org/index.php/Main_Page
      \nBruCON is an annual security and hacker conference providing two days of an interesting atmosphere for open discussions of critical infosec issues, privacy, information technology and its cultural/technical implications on society. Organized in Belgium, BruCON offers a high quality line up of speakers, security challenges and interesting workshops. BruCON is a conference by and for the security and hacker community. \n

      \n

      The conference tries to create bridges between the various actors active in computer security world, included but not limited to hackers, security professionals, security communities, non-profit organizations, CERTs, students, law enforcement agencies, etc.....\n

      \n

      \nHackers are \"persons who delight in having an intimate understanding of the internal workings of a system, computers and computer networks in particular.\" People who engage in illegal activities like unauthorized entry into computer systems are called crackers and don't have anything to do with hacking. BruCON doesn't promote any illegal activities and behavior. Many hackers today are employed by the security industry and test security software and systems to improve the security of our networks and applications. In addition, for the younger generations, we want to create some awareness and interest in IT students to learn more about IT Security.\n

      \n

      \nTrainings are planned for Sep 24-25, the conference for Sep 26-27. BruCON 2012 will be in the historic center of Ghent, Belgium.\n

      BlinkenArea

      \n

      \nThen off to the BlinkenArea to learn how to solder under the able eye of Arne Rossius. \n

      \n

      \nWelcome in the BlinkenArea, the portal for \"blinken\" [=flashing/sparkling/blinking] projects. The BlinkenArea is a project group of people who are interested in computers and electronics and in a creative handling of both of it. They attend to the research and operation of flashing projects. In the meantime, more than 60 hard- and software projectes were developed. The group grows constantly and the number of small and big projects rises as well. The major projects have been the pixel room TROIA and the display building bluebox. Detailled information about all projects is available on the page Projects. News are always published in the BlinkenArea Blog.\n

      \n

      Origin and motivation

      \n

      The page BlinkenArea tells you more about history, background and motivation. Apart from realising projects, the BlinkenArea people set their sights on collecting money which is scheduled to flow into public welfare, e.g. by selling own developed assembly kits or campaigns within bigger projects. The attention is focussed on supporting children, fighting against poverty and spreading education. Information about the social engagement of the BlinkenArea people can be found on the page Campaign. The BlinkenArea set further objectives which are listed on the page Goals.\n

      \n

      Contribute

      \n

      Everybody who is interested in our \"blinken\" projects and wants to contribute or support our honorary work is cordially welcomed. We are always looking for software engineers, tinkerer, translators, news editors, designer, musicians (set movies to music), and -- of course -- new projects. If you want to join the BlinkenArea, please visit the page Join. The BlinkenArea runs a Mailinglist and a discussion forum where you can ask questions, join in the conversation or just read along. \n

      PyOpenCL

      \n

      \nhttps://mathema.tician.de/software/pyopencl\n

      \n

      PyOpenCL lets you access the OpenCL parallel computation API from Python. Here's what sets PyOpenCL apart:

      \n
        \n
      • Object cleanup tied to lifetime of objects. This idiom, often called RAII in C++, makes it much easier to write correct, leak- and crash-free code.
        • \n
      • Completeness. PyOpenCL puts the full power of OpenCL's API at your disposal, if you wish.
        • \n
      • Convenience. While PyOpenCL's primary focus is to make all of OpenCL accessible, it tries hard to make your life less complicated as it does so--without taking any shortcuts.
        • \n
      • Automatic Error Checking. All OpenCL errors are automatically translated into Python exceptions.
        • \n
      • Speed. PyOpenCL's base layer is written in C++, so all the niceties above are virtually free.
        • \n
      • Helpful, complete documentation and a wiki.
        • \n
      • Liberal licensing (MIT).
        • \n

      PyCUDA

      \n

      \nhttps://mathema.tician.de/software/pycuda\n

      \n

      PyCUDA lets you access Nvidia‘s CUDA parallel computation API from Python. Several wrappers of the CUDA API already exist–so what's so special about PyCUDA?

      \n
        \n
      • Object cleanup tied to lifetime of objects. This idiom, often called RAII in C++, makes it much easier to write correct, leak- and crash-free code. PyCUDA knows about dependencies, too, so (for example) it won't detach from a context before all memory allocated in it is also freed.
        • \n
      • Convenience. Abstractions like pycuda.driver.SourceModule and pycuda.gpuarray.GPUArray make CUDA programming even more convenient than with Nvidia's C-based runtime.
        • \n
      • Completeness. PyCUDA puts the full power of CUDA's driver API at your disposal, if you wish.
        • \n
      • Automatic Error Checking. All CUDA errors are automatically translated into Python exceptions.
        • \n
      • Speed. PyCUDA's base layer is written in C++, so all the niceties above are virtually free.

      \nElectromagnetic Field (EMF) is a non-profit UK camping festival for those with an inquisitive mind or an\ninterest in making things: hackers, geeks, scientists, engineers, artists, and crafters.

      \n

      \nIn the summer of 2012 we gathered hundreds of people in a field outside Milton Keynes for three days of\ntalks and workshops covering everything from genetic modification to electronics, blacksmithing\nto high-energy physics, reverse engineering to lock picking, computer security to\ncrocheting, and quadcopters to beer brewing.\n

      \n

      \nTo help matters along, we arranged a 380-megabit internet connection, reliable WiFi, and a bar stocked with real ale.\n

      Open Garage

      \n

      \nThe \"Open Garage\" is a double garage in Borsbeek, Belgium, some sort of hackerspace, where I host weekly workshops and many of my projects. The garage is open every Thursday evening to everyone who wants to join our community's numerous hacking projects.\n

      \n

      \nJust be excellent to each other (principle #1 out of 1), bring a drink, a project and a friend and we're all set.\n

      \n

      \nI have all the tools and basic stock for elementary wood and metal working. Electronics gear and misc materials are available to tackle various projects. I also run a nano brewery from my garage, try to convert a car to electric, have a printrbot/Wallace++ 3D printer and we are trying to get a professional CNC mill and CNC lathe to work and I want to build a toolset for some DIY biotech, among many other things.\n

      \n

      \nProjects that have been successfully tackled or demoed at the garage are 3D printers and CNCs, a weather balloon, quadcopters, soldering and welding tutorials, a Tesla coil, beer brewing, a compost filtering machine, Arduino and Raspberry Pi projects, a windbelt, a Rubens' tube and many tens of other thingamajigs.\n

      \n

      \nFor those that may be new and interested: There's usually a few technology-minded people that drop by on random Thursday evenings with \"goesting\" to make. Some people bring a project and others bring their skills to collaborate on others' projects. (and there's a lot of nerd talk) If you're into that kind of stuff, feel free to drop by.\n

      \n

      \nIt is NOT required for your skills be on a high level, you are NOT required to contribute knowledge; instead, it is encouraged that everyone LEARNS stuff at our gatherings.\n

      \n

      \nI'd like to push my regulars to RSVP to the events, there's a lot of useful features in Meetup to share all kinds of stuff if you become part of the game ...\n

      Too Clever For Your Own Good

      \n

      This is a story about being so lazy that I'd rather teach the computer to do something than learn how to do it myself. HPR episode 1216 (https://hackerpublicradio.org/eps.php?id=1216) piqued my curiosity, but rather than try to remember my Morse code, I decided I could teach the computer to translate it for me. This episode tells that story.

      \n

      Commands

      \n

      Uncompress the audio

      \nsox hpr1216.ogg hpr1216.wav\n

      Get the format data

      \nsoxi hpr1216.wav\n

      Figure out how long the wav header is so we can skip it

      \nsox -t raw -b 16 -r 44100 -c 1 -e signed-integer /dev/null empty.wav\n

      Dump the audio data in a text format

      \nhexdump -s 44 -v -e '220/2 \"%04x\"' -e '\"\\n\"' hpr1216.wav > hpr1216.hex\n

      Convert values near 0 to spaces so it's easier to parse (at least visually)

      \nsed -e 's/000./    /g' -e 's/fff./    /g' hpr1216.hex > hpr1216.space\n

      Run it through the following awk script to make it readable by morse

      \nawk -f morse.awk hpr1216.space > hpr1216.dot\n

      And the script

      \n\n#morse.awk\n#every line\n{\n        last = this;\n        this = $0 ~ /^ *$/; #220 samples near 0, roughly 20ms of silence\n}\n\n#consecutive lines of silence or sound\nlast == this {\n        duration++;\n}\n\n#sound->silent state transition\n!last && this {\n        if(duration > 10 && duration < 20) #dit is roughly 18 lines or ~360ms\n        {\n                printf \".\";\n        }\n        else if(duration > 30 && duration < 40) #dah is roughly 36 lines, 720ms\n        {\n                printf \"-\";\n        }\n\n        duration = 0;\n}\n\n#silent->sound state transition\nlast && !this {\n        if(duration > 30 && duration < 40) #short gap (letter) is roughly 720ms\n        {\n                printf \"\\n\";\n        }\n        else if(duration > 80) #medium gap (word) is anything over 1600ms\n        {\n                printf \"\\n\\n \";\n        }\n\n        duration = 0;\n}\n\n

      Use morse to decode the translated output

      \nmorse -d < hpr1216.dot > hpr1216.txt\n

      And this is what it looks like

      \n

      IOS SOS SOS THE STANDARD EMERGENCY SIGNAL IN MORSE CODE. FOR EMERGENCY SIGNALS MORSE CODE CAN BE SENT BY WAY OF IMPROVISED SOURCES THAT CAN BE EASILY KEYED ON AND OFF MAKING IT ONE OF THE SIMPLEST AND MOST VERSATILE METHODS OF TELECOMMUNICATION. THE MOST COMMON DISTRESS SIGNAL IS SOS OR THREE DOTS THREE DASHES AND THREE DOTS INTERNATIONALLY RECOGNIZED BY TREATY. MORSE CODE FROM WIKIPEDIA THE FREE ENCYCLOPEDIA MORSE CODE IS A METHOD OF TRANSMITTING TEXT INFORMATION AS A SERIES OF ON-OFF TONES LIGHTS OR CLICKS THAT CAN BE DIRECTLY UNDERSTOOD BY A SKILLED LISTENER OR OBSERVER WITHOUT SPECIAL EQUIPMENT. THE INTERNATIONAL MORSE CODE ENCODES THE ISO BASIC LATIN ALPHABET SOME EXTRA LATIN LETTERS THE ARABIC NUMERALS AND A SMALL SET OF PUNCTUATION AND PROCEDURAL SIGNALS AS STANDARDIZED SEQUENCES OF SHORT AND LONG SIGNALS CALLED DOTS AND DASHES OR DITS AND DAHS. BECAUSE MANY NON-ENGLISH NATURAL LANGUAGES USE MORE THAN THE 26 ROMAN LETTERS EXTENSIONS TO THE MORSE ALPHABET EXIST FOR THOSE LANGUAGES. EACH CHARACTER LETTER OR NUMERAL IS REPRESENTED BY A UNIQUE SEQUENCE OF DOTS AND DASHES. THE DURATION OF A DASH IS THREE TIMES THE DURATION OF A DOT. EACH DOT OR DASH IS FOLLOWED BY A SHORT SILENCE EQUAL TO THE DOT DURATION. THE LETTERS OF A WORD ARE SEPARATED BY A SPACE EQUAL TO THREE DOTS ONE DASH AND TWO WORDS ARE SEPARATED BY A SPACE EQUAL TO SEVEN DOTS. THE DOT DURATION IS THE BASIC UNIT OF TIME MEASUREMENT IN CODE TRANSMISSION. FOR EFFICIENCY THE LENGTH OF EACH CHARACTER IN MORSE IS APPROXIMATELY INVERSELY PROPORTIONAL TO ITS FREQUENCY OF OCCURRENCE IN ENGLISH. THUS THE MOST COMMON LETTER IN ENGLISH THE LETTER E HAS THE SHORTEST CODE A SINGLE DOT. MORSE CODE IS MOST POPULAR AMONG AMATEUR RADIO OPERATORS ALTHOUGH IT IS NO LONGER REQUIRED FOR LICENSING IN MOST COUNTRIES INCLUDING THE US. PILOTS AND AIR TRAFFIC CONTROLLERS USUALLY NEED ONLY A CURSORY UNDERSTANDING. AERONAUTICAL NAVIGATIONAL AIDS SUCH AS VORS AND NDBS CONSTANTLY IDENTIFY IN MORSE CODE. COMPARED TO VOICE MORSE CODE IS LESS SENSITIVE TO POOR SIGNAL CONDITIONS YET STILL COMPREHENSIBLE TO HUMANS WITHOUT A DECODING DEVICE. MORSE IS THEREFORE A USEFUL ALTERNATIVE TO SYNTHESIZED SPEECH FOR SENDING AUTOMATED DATA TO SKILLED LISTENERS ON VOICE CHANNELS. MANY AMATEUR RADIO REPEATERS FOR EXAMPLE IDENTIFY WITH MORSE EVEN THOUGH THEY ARE USED FOR VOICE COMMUNICATIONS. THERE ARE MANY APPLICATIONS IN LINUX TO HELP YOU LEARN MORSE CODE. CHECK OUT RADIO.LINUX.ORG.AU FOR A LIST OF APPLICATIONS.

      \n

      A little googling will show that this text is the brief description of Morse code given at the top of its Wikipedia article (https://en.wikipedia.org/wiki/Morse_code). Surprisingly, the only transcription error appears to be the first letter as it was slightly overlapped by the intro music. It's also interesting to note that, since music consists of almost no sounds this short, the script was able to extract the data and robustly ignored everything else. In light of this, I probably could have skipped removing the wav header. Additional time could be saved by changing the regex in the awk script to match the raw hex values and thereby eliminate the sed step.

      \n\n

      \nWe had to wait 8 days for a Dinosaur egg to hatch, so we rigged up a RasberryPi with a cheap usb cam to take pictures. This was just before the camera module was releases. However the principle was the same. We positioned the egg in a mixing bowl and placed it on some boxes to give it height. Then we used the handle of a camera stand as a place to clip on a cheap usb camera. We then connected the camera to a RasberryPi.\n

      \n

      \n\"the\n

      \n

      \nOn the first day we let the light in and you see flickering as the lighting conditions change over the course of the day and the camera adjusts. Peter64 has promised a episode on how to fix this. So we closed the curtains and added an artificial light source as can be seen below.\n

      \n

      \nWhile we could have used fswebcam to automatically take the pictures, there was a certain satisfaction in seeing the program run every minute. Other than the default Raspbian install, we installed fswebcam and screen. The first to take the pictures and the other to allow the script to continue running after we disconnected.\n

      \n
      \n$ cat egg.bash\n#!/bin/bash\nwhile true\ndo\n  nowdate=$(date -u +%Y-%m-%d_%H-%M-%SZ_%A)\n  echo ${nowdate}\n  fswebcam -r 640x480 \\\n           -S 15 \\ \n           --flip h \\\n           --jpeg 95 \\\n           --shadow \\\n           --title \"Dinosaur Hatching\" \\\n           --subtitle \"Pádraig Fallon\" \\\n           --info \"\" \\\n           --save egg-${nowdate}.jpg\n  sleep 1m\ndone\n
      \n

      \nThat produced a big long list of images, 10886 in total, and it was a \"simple\" matter to convert them to a mp4 file with ffmpeg. See https://diveintohtml5.info/video.html for more information on encoding for the web in general\n

      Twitter/Identi.CA: @rileyinchina(Twitter)

      \n

      How to properly evangelize technology or why I use linux as my daily driver.

      \n

      Background:

      \n

      I started linux in 2007 with ubuntu 7.04 because I bought a cheap laptop in china that only had the entry level windows vista in the belief that I could change the language. I use linux on both my work and home pc’s htpc and a server, it really is just amazing the different applications and things you can do with it.

      \n

      Current PC is using: ubuntu 12.04

      \n

      Some rules of the road:

      \n

      Find the right time to broach the subject.Maybe when a person has to reinstall windows or they get a virus, or need to repurchase some piece of DRMed software.

      \n

      Don’t talk down to anyone, laugh at them or be a jerk. The people we are trying to convert don’t use linux everyday or probably have a vague idea or understanding of what linux is, your mission is to be as patient as possible.

      \n

      Don’t harp on how bad the system they are currently using is, find a situation in which they could benefit from the use of linux. The reason why fanboys exist is because we have this inherent need to not believe we are not wrong, if we are not wrong then surely the other guy is.

      \n

      Don’t attempt to tell the person what free as free not free as in beer is. News alert, nobody cares, unfortunate as it may be nobody cares about these things.

      \n

      Use practical examples as to why open source just works better: for me that’s wowing my coworkers by running a webserver on my desktop and having them test the various pieces of software before we settle on which one to put on our work server.

      \n

      Show them how you use linux or other open source projects in your daily life, to me the best WOW factor comes from XBMC on a Home Theatre PC, add in a PVR and you’ll easily see people’s mouths drop.

      \n

      Explain how open source is inherently more secure Linux has less exploited exploits

      \n

      Use current events: NSA, Viruses the end of lifing of XP to show them why they should at least attempt it.

      \n

      Ask them what they seriously use their computer for, my gut feeling is that about 75% of computer users don’t use anything on their computers that doesn’t already exist or have a worthy replacement in linux or an easy web application. And if worse comes to worse show them that they have the umbilical cord of WINE and or a virtual machine.

      \n

      Appeal to their frugality:

      \n

      Finally but probably most importantly put your money where your mouth is if you are taking the time to evangelize a product give a person some insurance:

      \n
        \n
      1. Give a guaranteed tech support certificate to anyone that is willing to try.
        2. \n
      2. Tell them to give linux a one day, one week and one month trial.
        3. \n
      3. Help them install it.
        4. \n
      4. Train them, most of us know that desktop linux is for all intents and purposes essentially the same as desktop Windows or Mac OSX
        5. \n

      Getting Started

      \n

      \"Home

      \n

      Audioimprovised extract (49sec). The improvised extract shows the quality that can be achieved with a fairly simple audio studio setup. The podcast outlines a number of useful tips and describes my method in achieving a virtually total Linux solution in my workflow. See also earlier HPR episodes-hpr0712 and hpr0755.

      \n

      My studio at home is in a spare-bedroom; a room, just 16x12 feet, with no special sound-proofing, just full bookcases all around the walls. The sound is quite 'dead' and OK for recording 'speech' which I do using a Zoom H4n Recorder, mounted on a small tripod, with 'pop' filter, and remote-controller to switch on and off.

      \n

      The vox part is one long file with pauses where the audio will be inserted. The file is saved to the PC as a WAV file into a master folder and, within that, three sub-folders to hold 'media' and 'text' files and a 'building' folder to assemble the final recording.

      \n

      The solo instruments and backing tracks are recorded through a USB mixer attached to the PC. Audio-improvised extract (45sec) from my composition Summer Dancin'. The piece was completely realised using the home set-up and Impro-Visor (https://bit.ly/EYbcv), which is similar to Band-in-a-Box with built-in rhythms and backings.

      \n

      My approach to writing musical themes is either 'melody' first or 'chord' sequence first. With Summer Dancin' it was 'chord' sequence first. I improvised a theme, live at the keyboard over a chord sequence and samba rhythm, using Impro-Visor. The main difference between Impro-Visor and Band-in-a-Box is that Band-in-a-Box uses sampled sounds to make up the backings, etc., whereas Impro-Visor's sounds are synthesised.

      \n

      AudioSummer Dancin'-theme (51sec). The harmonic sequence for the tune is fairly complex; as is the melody. To achieve similar results needs a fair grounding in jazz-type harmony and improvisation. Any approach, be it simple or complex, will work equally effectively using this basic method.

      \n

      What's in my music production 'Bag'?

      \n

      My main machine, is a basic PC desktop Acer Aspire SA80 with only 1 GB of ram. It has an Intel Pentium 4 processor and dual monitors. Xubuntu 12.04, LTS is the desktop and I use the on-board sound card. I have a small Yamaha PSR-350 keyboard attached via a Midiman MidiSport 2x2 interface. The Yamaha provides additional sound sets and it is through this that the backings are provided. The mixer is a Behringer Xenynx 1204FX and I use a variety of dynamic and studio capacitor microphones, with stands and 'pop' filters and the Zoom H4n Recorder. Audioimprovised extract (54sec)

      \n

      Process & Procedure for Podcasts

      \n

      For the instrumental portions, I mostly record straight into Audacity with the Band-in-a-Box backing track inputted to one channel of the mixer, and the instrument 'miked' to a second channel. A small amount of effect is added to the 'miked' channel while the 'backing' track is kept 'flat.' These are 'mixed' down to a single mono track at 44100 Hz and exported and saved as a FLAC file. The solo Bumpers are just simply improvised and recorded on to a single Audacity track.

      \n

      To assemble the podcast, I place the vox recording on the top track and split and move the track at the point where I insert an audio clips. These are dragged into Audacity on a separate track and the cut part of the vox track, moved to the right, as necessary. If I need to record using separate tracking, then I use Ardour. I often produce the music in score and parts for subsequent 'live' performances. The written music is produced using Sibelius 4 and the backings are generated with an old copy of Band-in-a-Box. Neither have been ported to Linux so I run them under Wine which is OK but it means only older copies of programmes will run. This is no problem, however, as the older versions provide all the functionality that I need.

      \n

      Keeping It All Together

      \n

      Well, regular practice is a important to stay 'up-to-speed.' Besides essential scales and arpeggios, for a jazz musician, a solid amount of improvisation practice is necessary. Band-in-a-Box is an ideal tool for this, providing a backing track similar to the well-known Aebersold method. Audioimprovised extract (54sec).

      \n

      Well, thats' all for now. Watch 'this space' for further developments. Cheers for now . . .

      \nThe Stanford marshmallow experiment (wiki) refers to a series of studies on delayed gratification in the late 1960s and early 1970s led by psychologist Walter Mischel, then a professor at Stanford University. In these studies, a child was offered a choice between one small reward (sometimes a marshmallow, but often a cookie or a pretzel, etc.) provided immediately or two small rewards if he or she waited until the experimenter returned (after an absence of approximately 15 minutes). In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI) and other life measures. However, recent work calls into question whether self-control, as opposed to strategic reasoning, determines children's behaviour.\n

      \nIntroduction: Units are the bridge from learning abstract arithmetic \n  operations on numbers to actually using maths to navigate the world of \n  objects, distance, time, rates, volume, temperature, heat, current,\n  voltage, and even cooking using recipes.\n\nGoal for the series: Embracing units, and carrying them along as you go,\n  can help you work with confidence in using maths in your life. \n  \n  When you start to use maths to solve real problems, you are going to \n  run into units.  This series is intended to show you that units are\n  your friends, and that they're here to help you.\n    \nGoal for this episode: We want to look at what units are, what they do, \n  types of units, and how to mix unitless numbers with units.\n  \n\nResource for the series:\n\n * Khan Academy pages on Rates, Ratios and Units\n   https://www.khanacademy.org/math/arithmetic/rates-and-ratios\n\n\nMost articles that would be relevant to this introductory episode were\nabout teaching physics and chemistry, or discussions of philosophical \nimplications of doing what we will be doing at every turn in this \nseries.  \n\nAll of the formal operations that we will learn to do with units are\ndone every day in real life by experts in their respective fields.  I am\nnot worried about what it means to say, \"There are 12 inches in a foot.\"\n\nLater shows will have more links and resources.\n\n\nSegment 1:  What do we mean by units?\n\n1. Definition: Two types of units are useful in practical maths:\n   \n   a. Counting units: An individual thing treated as single or complete.\n      Units can also apply to an individual component of a larger or \n      more complex system.  E.g., mufflers can become part of a car. \n\n      - Think of objects that you would keep in an inventory in your \n          pantry or in a warehouse.\n\n   b. Measurement units: A quantity chosen as a standard that you can \n      use as a common benchmark for comparing other quantities (of the\n      same kind).\n\n      - \"Same kind\": Don't try to compare distances to times or volumes.\n      \n      - \"Standards\": Communication tool for talking about quantities\n            without being face-to-face.  If you have standard units,\n            you avoid expressions like \"yea long\", \"kind of tall\", etc.\n      \n      - Probably invented by buyers and sellers, or by the spouse of an\n            avid fisherman.\n\n   c. Composite units: Units can be multiplied together (or divided) to\n      create new types of units.  Some people call these \"derived\n      quantities\", but that may sound too much like programming talk.\n      I use composite units because of the mental picture it creates of\n      putting things together, or doing one operation after another.\n      \n      - Dimensionality changes: \n        * 1 ft * 1 ft = 1 square foot: distance^2 --> area\n        * 1 ft * 1 ft * 1 ft = 1 cubic foot: distance^3 --> volume\n        \n      - Rates: \n        * Speed: distance / time = average speed, as in kilometers/hour\n        * Flow rates: volume / time, as in liters/minute\n        * Pressure: force / area, as in pounds / square foot\n        * Density: mass / volume, as in kilograms / liter\n        * Rationing: (1 period) counting units / time, as in apples/day\n                  (longer time) apples / family_member / day\n      \n      - We will run more of these types of units in later shows.\n       \n   \n2. Other kinds of numbers: Not every quantity has units attached\n\n   a. Numbers can be unitless. Unitless numbers help you make sense of\n         quantities with units through comparisons, extrapolations, etc.\n         \n     - Example: Percent changes are unitless floating point numbers, \n          unless it is tied to an elapsed time.  That's a \"rate\", which\n          has units of \"% per year\" (say).\n            \n     - Example: Percentage of Total values are unitless fractions, too.\n     \n     - Example: Any unit can be multiplied by a unitless integer.\n          * 2 feet, 3 apples, 4 quarts, 10 meters, etc.\n          * \"Twice as many\", \"ten times as far\", \"double a recipe\"\n     \n     - Counting units can be multiplied by a unitless fraction, but the\n          result will be rounded off to the nearest integer value.\n          * \"Mary has 2-1/2 times as many apples as John,\" is fine if\n               John has 4 apples, and Mary has 10 apples.\n          \n     - Example: Measurement units can be multiplied by any arbitrary\n          scale factor.\n          * How big: \"A land area 3.6 times the size of New Jersey...\"\n          * How far: \"I'll meet you halfway...\"\n          * How much: \"If using white flour, you'll need 30% more...\"   \n\n   b. When values with units are divided by other values with the very\n        same units, the result is a unitless number.\n      - Percent of Total and Percent Change are prime examples\n      - Comparison of distances: \n        * \"St. Johnsbury is 45 miles away, and Barton is only 15 miles.\n             So you have to drive 3 times as far to get to St. J.\"\n      \n   c. Conversion factors between units work in this way.  They are given\n          as ratios of some number of new_units divided by some other\n          number of original_units.  \n        \n        * The original_unit quantities cancel in multiplication, just as\n            numbers do, so you get an answer with the correct units!\n        \n        * You could call conversion factors \"derived quantities\", \n            because you create them from something called an identity,\n            or a statement of equality that you know to be true. \n   \n   d. Conversion factors will be covered next time.\n   \n   \n3. Why bother with \"counting units\"?  Aren't these just names?\n\n   a. Counting units are labels or names applied to individual items in\n      a total count, but they are still useful.\n   \n   b. Using counting units helps us to make distinctions between items\n      that are not interchangeable, so we can keep track of the counts\n      for each individual kind of item.\n      \n      - If you need 2 apples, having 10 onions does not help you.\n   \n      - Thinking with units will help you keep inventories and to start\n           setting up accounting systems for your business.  It will \n           also help you manage your kitchen and your budget at home.\n      \n\nSegment 2: Counting Units?  Are you serious?\n\n1. Counting units give context to the numbers that you are using in any\n   calculations that arise when you are buying, selling, trading or just\n   using up items in a beginning inventory.\n   \n   Here's what happens when you don't track units in counting problems.\n   \n   - Example: \"John has 9 apples in his basket.  If he gives 2 apples\n     to Mary, how many does he have left?\"\n     \n   - Speed test preparation textbooks seem to teach you to parse the \n     problem as if you were a word problem \"compiler\":\n\n     a. Fish out the numbers and their roles.\n       \n        --> Notice that 9 is near \"in his basket\", \n                              and \"how many does he have left?\", \n            \n            It must be the source.\n\t\n\t    --> Notice that 2 is next to \"gives away\". \n\t    \n\t        It must be the change in quantity.\n\t\n     b. Parse out the operation: \"gives away\" is code for subtraction.\n\n     c. Do the calculation and supply a numerical answer: 9 - 2 = 7\n\n\n2. Re-work the problem by tracking units.\n   a. Read the problem.  I'll wait.  We will parse it together.\n   b. John has a basket with 9 apples in it --> beginning inventory\n   c. John gives away two (2) apples to Mary.\n      - John's inventory of 9 apples is reduced by 2 apples, \n      - John now has 7 apples in his basket.\n      \n   d. Mary now has 2 additional apples in her inventory.\n      - The apples were neither created out of nothing nor destroyed.\n      - They came from somewhere (John), and they went somewhere (Mary).\n      - If \"apples out\" does not equal \"apples in\", something's wrong. \n   \n   e. Having this information lets you answer questions with confidence.\n   \n   f. Answer the question: \"John now has 7 apples.\"\n      - John does not have '7'.  John has '7 apples'.\n\n\n3. Ho hum.  That solution is exactly the same. You're picking nits.\n\n   a. For a trivial problem, this looks the same.  But there are some \n      benefits of using units, even if they appear to be \"just labels\".\n \n   b. If the problem had said that \"John gave 2 oranges to Mary\", we\n      would have spotted the discrepancy immediately.\n      - Giving away oranges does not affect John's apple inventory\n      - The oranges must have come from another supply (account)\n      - We can still talk about an increase in Mary's oranges count, and\n          the decrease in John's oranges -- even though we don't know\n          the beginning or ending balances.\n   \n   c. What if the problem had said, \n         \"Mary has three times as many apples as John.  How many apples\n           would Mary have to give to John to leave each of them with \n           the same number of apples?\"\n   \n   d. Better yet, what if the problem read:\n         \"John has 19 apples, and Mary has 14 oranges. Now John likes \n           oranges twice as much as he likes apples, but Mary likes \n           apples three times as much as she likes oranges.  \n           \n           How can John and Mary exchange apples and oranges to get the \n           best (equal) gain in happiness?\"\n\n      - This problem involves not only the tracking of apples and \n          oranges, but probably some type of \"happiness\" function \n          that gives a value that carries some kind of units.\n        \n        Warning: There's not enough information to really solve this\n          problem without further assumptions.  It is meant as an \n          illustration of how complicated a setup can become when you\n          get into real life situations.\n      \n      - Problems like this are what make people hate economics.  One \n          way to solve it is to define utility functions for each party.\n      \n      - Their preferences are so different from their inventories, that\n          simply trading baskets is pretty close to an optimal solution.       \n      \n   e. If the problem had involved trading some of John's apples for \n        some of Mary's oranges, and possibly an offsetting cash payment\n        to correct an imbalance, we would make the best use of our \n        information about the sources and uses of resources by tracking\n        the units of each object or currency involved in the exchange.\n   \n      Point:  Problems can become complicated.  Units can help with the\n              bookkeeping needed to work through to the answers.\n\n              If someone poses a problem like this one to a group at a\n              dinner party, it is time to remember that you forgot to\n              iron your curtains.\n              \n              \n4. Final properties of counting units\n\n   a. Compatible counting units can be added and subtracted.\n      - Example: 6 apples + 4 apples = (6 + 4) apples, or 10 apples.\n      - Example: 6 apples + 2 oranges is a mixed expression.  They \n          cannot be added, except as part of a fruit salad.\n   \n   b. An amount that's given in counting units can be multiplied by an \n        integer, since that is like repeated additions.  They can also\n        be multiplied by a fractional amount, but we would want to \n        interpret the result as a whole number.\n        \n   c. Any multiplication by a floating point number would have to be \n      defined, and it's usually not worth the effort.\n   \n   d. Counting units have weaknesses, especially in classification:\n      - Organic items are usually not identical.  Apples can vary. \n        * Size: A recipe calls for \"3 large apples\".  Are these large?\n        * Varieties: \"Apples\" in the US can include Macintosh, Rome, \n             Gala, Granny Smith, etc.  These can be quite different.\n       \n      - Animals also vary within categories:\n        * Cats: Lions, lynxes and Little Puff can all qualify\n        * House cats: Siamese, Persians, Tabby cats are all just cats,\n            until you have them living in your home.\n      \n      - Some living things are hard to pin down: sponges, paramecia\n      \n      - Other items can also create classification issues, depending on\n           your purpose.\n        * Units are just tools.  Let them work for you, and not the \n            other way round.\n\n\nSegment 3: Units of measurement\n\n1. Measurement units are often continuous (or just about), so they can\n     be divided conceptually into smaller and smaller subunits as many\n     times as we like.  \n\n   - They can also be lumped together into larger and larger wholes.\n\n   - Physical limitations place practical limits on how finely we can\n       actually chop things up, and still get a measurement.\n       \n   - There are real world limitations on how much we can lump together.\n\n   - But you get the idea.\n\n\n2. Measurement units can be applied to distance, time, area, volume, \n     weight or mass, energy, frequencies of light or radio waves, \n     voltages, current, heat, temperature, and a host of other things.\n\n   - We can measure these quantities with differing levels of precision,\n       based on the instruments and abilities that we have.\n\n   - For all practical purposes, we measure within tolerances that we\n       can meet without spending our whole lives measuring. \n\n\n3. Applications of measurement units\n\n   a. Understanding the news: hectares of forest endangered by a fire,\n        square miles of arable farmland in South Africa,\n        temperatures given in unfamiliar scales such as Fahrenheit,\n        snowfall measurements in Canada versus neighboring Montana, etc.\n   \n   b. Following recipes to make bread, cookies, beer and other items \n        that promote World Peace\n   \n   c. Mixing chemicals for an old-school darkroom, or for a very cool \n        low-tech electronics home \"fab lab\"\n   \n   d. Buying gasoline (petrol) in other countries, and understanding\n        their speed limits in foreign units.\n        \n      - Can't help you with driving on the wrong side of the road\n   \n   e. Helping your kids with their maths homework, and understanding it\n        for once!\n   \n   f. Checking the dosages of your medications against your prescription\n         to find out if this is my medicine or my child's.  You just\n         have to be able to get this one right.\n\nWe'll get to all of this and more in future episodes in this series.\n

      Manually installing packages from the AUR

      \n

      Since completing my conversion from Cinnarch to Antergos, (https://antergos.com/antergos-2013-05-12-were-back/, the published tutorial didn't work for me the first time, but the new Antergos forums were most helpful (https://forum.antergos.com/viewtopic.php?f=28&t=944&p=2892#p2892), a few utilities I installed under Cinnarch seem to be unavailable, notably, 'yaourt' Yet An Other User Repository, the package manager for the AUR (Arch User Repositories).[The AUR are unofficial, \"use at your own risk\" repositories, roughly analogous to using a ppa in Ubuntu.] I tried 'sudo pacman -S yaourt' and learned it wasn't found it the repositories (I should note that when I removed the old Cinnarch repos from /etc/pacman.conf, I must have missed including the new Antergos repos somehow). I have since completed the transition.

      \n

      Anyway, some experienced Arch users like Peter64 and Artv61 had asked me why I was using yaourt anyway instead of installing packages manually, which they considered to be more secure. I decided to take the opportunity to learn how to install packages manually, and to my surprise, it was not nearly as complex as I had feared. I had promised a series of podcasts along the theme, \"So, you've just installed Arch Linux, now what?\" This may seem like I've jumped ahead a couple steps, but I wanted to bring it to you while it was fresh in my mind.

      \n

      Your first step may be to ensure you really have to resort to the Arch User Repositories to install the app you are looking for. I'd found Doc Viewer allowed me to access PDFs in Arch, but I really preferred Okular that I'd used in other distros. When 'sudo pacman -S okular' failed to find the package, I assumed it was only available from the AUR. However, a Google search on [ arch install okular ] revealed the package I needed was kdegraphics-okular, which I installed from the standard Arch repos.

      \n

      Once you've determined the package you need exists in the AUR and not in the standard repos, you need to locate the appropriate package build, your Google search will probably take care of that. The URL should be in the form http:aur.archlinux.org/packages/<package-name>. For the sake of example, lets go to https:aur.archlinux.org/packages/google-chrome/. Chromium is already in standard Arch repos, but if you want Chrome, you will have to find it in the AUR. Find the link labeled \"Download the tarball\", it will be a file ending ing .tar.gz Before downloading a file, the Arch Wiki instructions for manually installing packages from the AUR https://wiki.archlinux.org/index.php/Arch_User_Repository recommend creating a designated folder to put them in, they suggest creating a \"builds\" folder in your home directory.

      \n

      If you have a multi-core machine, you may be able to take advantage of a slight compiler performance increase by making adjustments to your /etc/makepkg.conf . Look for \"CFLAGS=\", it should have a first parameter that looks like -march=x86_64 or -march=i686 . Which ever it is, change it to -march=native and eliminate the second parameter that reads -mtune=generic . This will cause gcc to autdetect your processor type. Edit the next line, which begins with \"CXXFLAGS\", to read CXXFLAGS=\"${CFLAGS}\", the just causes the CXXFLAGS setting to echo CFLAGS. Details are located in https://wiki.archlinux.org/index.php/Makepkg.conf.

      \n

      Before installing your first AUR package, you will have to install base-devel, [ pacman -S base-devel , {as root, so become root or use sudo}]. Look for that .tar.gz file you downloaded, still using Chrome as an example, it's google-chrome.tar.gz . Unravel the tarball with \"tar -xvzf google-chrome.tar.gz\". Now, in your ~/builds folder you should have a new directory named \"google-chrome\". Drop down into the new folder. Since user repos are not as trusted as the standard ones, it might be a good idea to open PKGBUILD and look for malicious Bash instructions. Do the same with the .install file. Build the new package with \"make -s\". The \"-s\" switch lets the compiler resolve any unmet dependencies by prompting you for the your sudo password.

      \n

      You will have a new tarball in the format of <application name>-<application version number>-<package revision number>-<architecture>.pkg.tar.xz , in our google-chrome example, the file name was google-chrome-27.0.1453.110-1-x86_64.pkg.tar.xz . We install it with pacman's upgrade function \"pacman -U google-chrome-27.0.1453.110-1-x86_64.pkg.tar.xz\". This command will install the new package and create an RPM.

      \n

      Before running Arch, I did not realize spell checking was centrally configured in Linux, I always assumed each application had it's own spell checker. After installing Arch, I noticed auto-correct wasn't working anywhere. At length, I looked for a solution. I found Libre Office and most browsers rely on hunspell for spell checking functions. To get it working, you just need to install hunspell and the hunspell library appropriate for you language, i.e. \"pacman -S hunspell hunspell-en\"

      StraightTalk/Tracphone, a quick review.

      \n

      Before leaving for Philadelphia last spring, I decided I needed a cheap smartphone on a prepaid plan. The only one with reliable service in my area is StraightTalk, or Tracphone, sold in Walmart. For $35 a month, they advertise unlimited data, talk, and text. The one drawback, any form of tethering, wired or wireless, violates StraightTalk's TOS (frankly I missed that condition before buying the phone). Hmm, would Chromecast count? Anyway, for some people, no tethering would be an immediate deal breaker. Frankly, I can see the advantages to tethering, but the one scenario I'm most interested in is isolating an infected system from a customer's network, and still be able to access anti malware resources. The budget phone I bought only supports 3G, and I'm not in the habit of streaming media to it, much less sharing it to another device.

      \n

      That doesn't mean I don't use the bandwidth. I put a 16 gig SD card in my phone, and started using it as an additional pipeline to download Linux iso's. Anything I download, I can transfer to my network with ES File Explorer. I downloaded several Gigs in the first month to test the meaning of Unlimited. Towards the end of the month, and after I bought prepaid card for the next month, I had an off and on again data connection, I thought the provider was punishing me for being a hog, it turns out the phone was glitchy, and turning it off and back on again always re-establishes the data connection. Therefore, I am happy to report that StraightTalk actually seems to mean what they say when they advertise \"Unlimited\". Unfortunately, many of my direct downloads fail md5sum check. Direct downloads on 3G come down as fast as 75-100 MBps, but torrents seem to top out at 45MBps, the same as my home connection.

      \nWe hope to do another show soon, a Linux Camp Radio Show. We said in this interview that Linux Camp was a series of \"real world task\" labs, and we think that with a little work, they would make a good radio show. A show that an aspiring Linux SysAdmin, especially one that is studying for the LPIC-1 exams, could use as a list of challenge tasks to reinforce their skills.\n

Arch Lessons from a Newbie Ep 02: Some pacman tips","notes":"

      A while back, I used my Arch laptop to pre-configure a router for a customer, which of course required me set up a static IP on my eth0. I should have done this from the command line, instead I used the graphical Network Manager. I had a lot of trouble getting the graphical application to accept a change in IP, and in getting to go back to DHCP when I was done, and I wound up going back and forth between the Network Manager and terminal commands. I've mentioned before my ISP is behind two NATed networks, the router in the outbuilding where the uplink to the ISP is (this is also the network my server is on) and the router in my house. The static IP I used for the customer router configuration was in the same address range as my \"outside\" network Though I successfully got eth0 back on DHCP, there was a phantom adapter still out there on the same range as the network my server was on, preventing me from ssh'ing in. I did come across a hack, if I set eth0 to an IP and mask of all zeros, then stopped and started dhcpcd on eth0, I could connect. I had also used the laptop on a customer's WiFi recently, and the connection was horrible.

      \n

      I decided to see if just installing the wicd network manager would clear everything up (and it did), but before installing Wicd, I had to update the system, so first a little bit about pacman

      \n

      Arch's primary package manager is pacman. The -S operator is for sync operations, including package installation, for instance:

      \n# sudo pacman -S <package_name>\n
      ..... installs a package from the standard repos and is more or less equivalent to the Debian instruction .... 
      \n# sudo apt-get install <package_name>\n
      The option -y used with -S refreshes the master package list and -u updates all out of date packages, so the command 
      \n\n# sudo pacman -Syu .... is equivalent to the Debian instruction .... \n# sudo apt-get update .... followed by .... \n# sudo apt-get upgrade\n# sudo pacman -Syu <package_name1> <package_name2>\n\n
      would update the system, then install the selected packages
      Perhaps because of my slow Internet, the first time through a few of the update packages timed out without downloading, so nothing installed. The second time through, even one of the repos didn't refresh. Thinking this was a connectivity problem, I kept trying the same update command over and over. Finally, I enlisted the help of Google.
      'pacman -Syy' forces a refresh of all package lists \"even if they appear to be up to date\". This seems to automagically fix the timeout and connection problems, and the next time I ran the update, it completed without complaint. I was mad at myself when I found the solution, because I remember I'd had the exact same problem and the exact same solution before and had forgotten them. Podcasting your errors is a great way of setting them in your memory.
      About the same time, I ran out of space on my 10Gb root partition. I remembered Peter64 had a similar problem, but I found a different solution than he did.
      \n# sudo pacman -Sc\n
      .... cleans packages that are no longer installed from the pacman cache as well as currently unused sync databases to free up disk space. I got 3Gb back! 'pacman -Scc' removes all files from the cache.
      https://wiki.archlinux.org/index.php/Wicd
      Use pacman to install the package 'wicd' and if you want a graphical front end, 'wicd-gtk' or 'wicd-kde' (in the AUR). For network notifications, install 'notification-daemon', or the smaller 'xfce4-notifyd' if you are NOT using Gnome.
      None of this enables wicd or makes it your default network manager on reboot, that you must do manually. First, stop all previously running network daemons (like netctl, netcfg, dhcpcd, NetworkManager) you probably won't have them all. Lets assume for the rest of the terminal commands, you are root, then do: 
      \n# systemctl stop <package_name> i.e # systemctl stop NetworkManager\n

      Then we have to disable the old network tools so they don't conflict with wicd on reboot. 
      \n# systemctl disable <package_name> i.e. # systemctl disable NetworkManager\n

      Make sure your login is in the users group 
      \n# gpasswd -a USERNAME users\n

      Now, we have to initialize wicd 
      \n# systemctl start wicd.service\n# wicd-client\n

      Finally, enable wicd.service to load on your next boot up 
      \n# systemctl enable wicd.service\n

      Blogging with Octopress

      \n\n

      Static html site generators automate many of the tedious steps that are necessary\nto create website. Octopress is a static html generator that automates many of the tedious tasks of static html site generators, and comes with a number of reasonable presets, configured right out of the box.

      \n\n

      Static HTML Site Generators I looked at:

      \n\n

      \n I settled on octopress for the following reasons:\n

      \n
      \n
      SASS
      \n
      \n Sass adds additional functionality to css such as variables, mixins, \n scopes, and was a tool that I had previously worked with.
      \n
      Twitter Bootstrap
      \n
      \n Twitter bootstrap is a set of templates that produce nice looking \n pages that are standards compliant, and adaptive so that they look \n good at any screen resolution.
      \n\n
      HTML5 Video Plugin
      \n
      \n I ended up creating my own, but Octopress has a HTML5 video plugin. \n Unfortunately this only supported H264 video, so I created my own to \n serve H264, Webm, and Ogv.
      \n\n
      Deployment scripts
      \n

      \n

      Hello All,
      \n
      We are roughly around 10 weeks away from the next 24-hour New Year's show. This a call out for all parties who are interested in helping with this year's show. We mainly need to make arrangements for a Mumble server and a few streaming servers. If you have any of these resources available then please send me your name, email address, available resources, and a day/time that is convenient for you to meet on-line on a Mumble server for organizational purposes.
      \n
      Thank you,
      \n

      Hello hacker public radio

      \n

      I have wanted to contribute to HPR for several months now. I find it annoying and pointless to create a script to read off. But after several attempts of trying to recording my self blathering on with stuttering, cursing, air gaps, and humming I had to script my episode. In this episode I would like to talk about building a Christmas light synchronization system.

      \n

      I had first seen someone's home brew system years ago synchronized to music by the trans-Siberian orchestra. I was immediately mesmerized and went to work on figuring out how it was done.

      I have had a fair amount of experience with fabrication and electricity over the years. However I really only know how to maintain systems that have already been engineered and fully vetted by others. My exploration led me to first find all of the unreliable sources and then on to the sites that leave out the magic step into getting their system to work. Truly reliable sources were scarce.

      \n

      Frustrated with what I was finding, I gave up and my time was consumed with remodelling our home and moving to a different state into our new house.

      \n

      Last year I wanted to start another attempt at making a system but time was short and planning something like this during the holidays is extremely dumb.

      \n

      After the last holiday season and while putting away the holiday lights all I could think about is getting these lights synchronized for the next season. So I went back to the disinformation highway continuing my research.

      \n

      Although I was looking strictly for technical information personal information leaked through.

      \n

      The common theme amongst other people is to start planning for the next season in July. Starting to plan in January is a bad idea and all you will have is anguish when it comes time to deploy your show.

      \n

      Soon July came along and I argued with myself if I was really going to commit myself to doing this. From what I have read I can be reassured that there is no backing out once you start. Most people talk about what they are going to add to their system next year.

      \n

      So lets talk about the first step.

      \n

      Some sites will say \"GET AS MANY LIGHTS AS YOU CAN AS SOON AS POSSIBLE\"

      \n

      This theme seems like a logical step, but I don't know what I'm doing!

      \n

      I already have lots of lights, its not like I'm going to put up one hundred thousand lights this year. No my plans are to put up the same old lights I already have and incorporate them into the system and then grow from there.

      \n

      So if I already have some lights I need a new step one.

      \n

      Unfortunately most of the so called step by step lists don't agree on anything. So I chose what was most important just to get lights to work, even if I was never able to build my own synchronization system. The most important thing in any holiday lighting set-up is electricity. So that is the first thing I concentrated on. The front of my house has two outlets on two different circuits. One conveniently placed on the front porch, at the lowest spot on the porch with a plastic cover that is hinged to open upwards preventing direct line of sight when trying to plug an extension cord in. The second is behind a razor sharp ornamental grass bush. The two circuits are on 15 amp breakers and each outlet is installed with a ground fault circuit interrupter (GFCI). You make have seen these in your bathroom, they have a rest button and a test button. These circuits are not dedicated to these two outlets. They are connected to all of the rooms on the front side of the house. For me this simply will not do. Because when or if a breaker trips part of the house will go dark. Instead of fussing with these difficult circuits I decided to install two new circuits that would be exclusively dedicated for any out door lighting. My garage has a relatively empty breaker box so whatever I decide to do I'll have plenty of room to do it.

      \n

      With my mind on future needs I made a check list of what I wanted

      \n
        \n
      • # One. Two separate circuits
        • \n
      • # Two. 20 amps on each line
        • \n
      • # Three. The circuits need to terminate in two separate two gang boxes somewhere out in the yard where all the lights would connect to them.
        • \n
      And thats just what I did. From the breaker box I ran 12 gauge 3 wire (12/3) over head and down the wall into two separate junction boxes.

      A GFCI outlet is the first device connected from the home run between the breaker box and this junction box. So anything installed after this point will have GFCI protection. The second thing installed is a light switch that can create an open circuit to the power leaving the garage. I had thought about installing a digital timer instead of the light switches but the light switches are a cheap place holder until I make up my mind. the GFCI outlets and light switches are rated at 20 amps not 15. After the light switches, the circuits run out of the garage and are trenched about 30 inches below ground in PVC conduit. They reappear in a spot in the yard, terminated at the 2 gang outlets. This took quite sometime to do. All of my expenses are going into copper so the budget doesn't call for any machinery to help along the. So at this point regardless if I continue on with my adventures I should always have enough power just to run lights.

      \n

      As the month went on I stumbled across Instructables.com and found a few people actually showing their secret sauce. I probably spent a whole month reading and then rereading what they were doing. There were only about six people that truly knew how to make a synchronization system and they all had one thing in common, Arduino. Without even really knowing what an Aduino is, I knew this was going to be the key to getting a system of my very own! Without hesitation I linked over to adafruit and bought an Arduino Uno. Everyone else had one, so why shouldnt I?

      \n

      The Uno would only cost me $30 and I would be on my way to completing my goal. If you've never seen or heard of an Arduino they are credit card sized micro controllers that are made in Italy and are open sourced. The Arduino has one little hang up. Everything is programmed in C language. I know nothing of C or any real programming language. The only programing I have any experience with is HTML 1.0. These geriatric skills would not help me with the Arduino. Arduino helps you learn basic skills. You can read practice pages at Arduino.cc or you can use the Arduino examples built into their IDE software. The first tutorial I explored was the Blink command. The blink command you assign a name to the pin you want to use and then create a loop of turning the pin on and off, or HIGH and LOW. For me this was fun and now I am the lord of the blinks. I've been told that music is math. So I chose to experiment with this idea as my first arduino sketch. Arduino calls your program a sketch. So I found some sheet music with around eight notes. I printed the sheet music and then translated all of the notes into integers. Then I mapped the numbers to coordinate with the pins on ardunio. Uploaded the sketch and nothing happened.

      \n

      You cant see the electricity moving around on the Arduino, I need to do something to ensure the program is working. I run over to Radio Shack to try to remedy this hang up as soon as possible. Radio Shack carries Arduino parts, so I bought a prototyping board, resistors and LED's.

      \n

      LED's are great for flash lights and such. But when it comes to prototyping and experimenting LEDs are great indicators that circuits are working correctly. So I soldered up 8 leds, resistors and wires to the prototyping shield and placed the shield onto the Arduino.

      \n

      I plugged power into the Arduino in and the lights started blinking. I gave my self a mental high five and congratulated my brain on a job well done. This test was successful, it was time to move on to the next step. I had already been over on amazon browsing relays and found a company on there called SainSmart that has prebuilt relay modules. I picked out a module that had 8 relays on it. This module was about $9 and I didn't think that I would be able to build something as nice as this for the same price. What I did next is sloppy and dangerous. Don't do this, I did it because I was following other peoples' instructions. People think its OK to run 120v into shoe boxes or clear rubber made totes. I did mine in an $8 home depot tool box. I wired everything up correctly and tested the system. I was able to get 8 strings of light to blink but I wasn't very happy with what I had. My idea for making the sequence, looked nice when it was only 8 leds blinking in a two by two inch square. Translate that to strings with 100 bulbs and it doesn't look sequenced. In-fact it looks like a sloppy attempt at being random. Maybe even call it laggy. it was bad.

      \n

      I left out everything I had to do to get the system working because I don't want anyone to do this. Seriously don't run push high voltage into cheap plastic products. It's dumb and dangerous, I did it for you, so you don't have to.

      \n

      However this first experiment passed all of my tests and filled in all the gaps in my mind. I know exactly what to do now and I'll cover my new box in detail. I suppose I skipped over what a relay is. You can think of a relay as an electromechanical light switch. They use direct current to drive a magnet to mechanically move an internal switch to create an open or closed circuit. These are the the devices that make it physically possible to synchronize a light show. While running my first prototype system a blue genie escaped from the board so I only have seven of eight relays working. It didn't bother me too much that one of them was broken because my plans are to build a larger system. I went back to Amazon again and this time purchased another eight relay module and then two sixteen relay modules. When talking about syncro systems a relay is called a channel, so with all my new hardware I now have enough to do 47 channels. The ardunio UNO only has 17 usable pins. So I needed to build multiple system or get a new controller. So I got a new controller. My new controller is still an Arduino, but instead of being the UNO it is now the MEGA. The MEGA is advertised to have 54 input/output ports. This more than enough to drive the relays I have. The issues of a proper enclosure is not trivial. This system contains high voltage and direct current electronics. I chose a Cantex twelve by twelve by six inch PVC junction box. The lid has six screws and a gasket to make the enclosure water tight.

      \n

      The box was fairly expensive at thirty dollars but made everything feel better. In my collection of spare parts and junk I found a fist full of stand-offs and screws that actually had the same thread spacing. I drilled holes in the box and screwed in the stand-offs once I had the relays and Arduino parts mounted the way I liked I removed the hardware only leaving the screws and stand-offs.

      \n

      Around all of the mounting hardware I used a combination of hot glue, silicone caulk and PVC cement to insulate the metal screws and to make their connections water tight. With the lid open and looking into the box the entire back side of the box fits the MEGA and two 16 relay modules. On the six inch side walls I was able to mount the eight relay modules. Before I mounted the relays for the last time I wired them up for high voltage. The relays have three set screws. The center screw is the common hot wire. For example from relay one I have a short 14 gauge wire running out of this screw and into a four port wire nut. Ideal makes a Push-In Wire connector that has 4 ports. The ports are bussed together and make for a cleaner install when compared to a standard twist wire nut. One push in connector can connect two relays and then jumper on to the next wire nut with two more relays, so on and so on. So there are 4 total relay modules and I connected all the common hots among all of them this way. When it came to the 16 relay modules I used tall standoffs so I could hide all this wire under them. So these connections are a little bit longer. The set screws in these modules can only handle up to 14 gauge wire. So thats what I used throughout. Before placing the modules you need to look at the other two set screws and make a decision. to the right of the common hot is the open side and to the left of the common hot is the closed side. At this point you have to think about your Christmas lights. Do you want them to be off all the time and have the relays turn them on to create your sequence. Your default state will be to have a dark yard. I chose to have them on at all times and I was going to create sequences where I would be turning them off. So even if nothing is happening the default state will be that my yard will be bright with lights. I also chose this way because if something breaks along the way I don't have to run out and re plug everything just to have lights on. But be careful as this will become confusing as we go along, its inverted from tradition thinking. With the relays wired with common hots, I installed them into the box and screwed them in. After that I tied the modules hots together. But made it more complicated than it needed to be. For some dumb reason I decided to load balance my box. Two relays per circuit. Back to my power, I ran two lines A and B. In side my box I made it so there was an A and B side too. Honestly everything can be tied together and it won't stress the system out the slightest. All it does is makes things more complicated. The next thing I did was connect all of the DC cables in the system. I created connectors from bits and parts laying around. Old IDE cables are nice for this. I wanted a completely modular system in case anything failed. So nothing is hard-wired soldered. I started out on the MEGA with Pin 22 and wired one pin to one relay pin. over and over again 47 times.

      \n

      Then I created a power distribution board that distributes 12 volts to all of the relays and Arduino. I fitted everything up and ensured that everything fit and I had good connections. Then pulled the MEGA back out. Even though I have the relays in a box and all the hardware is connected the Mega has never been powered on. Its still dumb and doesn't know what it's supposed to be doing. Earlier I was talking about using sheet music to make a sequence and how that's a bad idea. I needed a new way to make blinky blinky. I found some popular windows software called Vixen Lights. Vixen is extremely granular lighting synchronization software. To the best of my knowledge it only works under Windows, although I have been trying to get it to work in WINE. Someday I'll get this to work. When you get Vixen up and running the screen looks like a spreadsheet, full of cells. Each cell represents time on a channel, double click the cell to turn it on or off. Some estimate that it could take several hours to synchronize three minutes of music. I'm not really concerned about making a sequence at this time. I move on because its more important to get a completed box in my mind. So let me help you spend some more money. When using Vixen the Ardunio needs to be connected to your computer via a USB cable. You'll configure Vixen to send serial to the com port that Ardunio is connected to. I have spare computers. But installing windows xp on a box and getting it configured is extremely annoying in its self. Then figuring out how to put a desktop in the yard adds to pointlessness. Some people might jump on the wifi bandwagon. There are to many devices on my network and I really don't want a power system to be available to the Internet. Plus why would you want your lights to be remotely operated like this. If you're not home why do you care if your lights are on or off. I'm doing this for me. The challenge is to eliminate the USB cable and keep it off the Internet.

      \n

      I found out about wireless radios called xbee's. They are expensive, but do exactly what I want. They create a wireless serial connection at 9600 baud. When you're out shopping for your own there are two different types of xbee's. S1 and S2. I believe the S2's are also called zigbees and you can make them more secure than the S1. I ordered the wrong ones, I ordered the S1's. The S1's are extremely easy to set up. But to set them up you need more hardware. I ordered a majority of my hardware from Adafruit. So along with two xbees, I also got two xbee adapter kits and one FTDI cable. After building the adapter kits and plugging in the xbees I wired one of them into the Ardunio. For the Arduino side all you need is four wires. Ground, five volt power, transmit, and receive. The Uno has one TX/RX connection while the Mega has four. This doesn't matter since all Ardunio needs to do is listen. On your computer all you need to do is plug in the xbee using the FTDI. It is recognized as serial I believe in both Windows and Linux no drivers were needed to make it work. The only computer configuration needed is changing in Vixen, you need to tell Vixen what port it needs to use to send serial commands. But before you test this, you need to give your Arduino instructions. Here is the sketch I created for my system:

      \nint C1 = 2;\nint C2 = 3;\nint C3 = 4;\nint C4 = 5;\nint C5 = 6;\nint C6 = 7;\nint C7 = 8;\nint C8 = 9;\nint C9 = 10;\nint C10 = 11;\nint C11 = 12;\nint C12 = 13;\nint C13 = 22;\nint C14 = 23;\nint C15 = 24;\nint C16 = 25;\nint C17 = 26;\nint C18 = 27;\nint C19 = 28;\nint C20 = 29;\nint C21 = 30;\nint C22 = 31;\nint C23 = 32;\nint C24 = 33;\nint C25 = 34;\nint C26 = 35;\nint C27 = 36;\nint C28 = 37;\nint C29 = 38;\nint C30 = 39;\nint C31 = 40;\nint C32 = 41;\nint C33 = 42;\nint C34 = 43;\nint C35 = 44;\nint C36 = 45;\nint C37 = 46;\nint C38 = 47;\nint C39 = 48;\nint C40 = 49;\nint C41 = 50;\nint C42 = 51;\nint C43 = 52;\nint C44 = 53;\nint C45 = 54;\nint C46 = 55;\nint C47 = 56;\nint i = 0;\nint incomingByte[47];\nvoid setup()\n{\nSerial.begin(9600);\npinMode(C1, OUTPUT);\npinMode(C2, OUTPUT);\npinMode(C3, OUTPUT);\npinMode(C4, OUTPUT);\npinMode(C5, OUTPUT);\npinMode(C6, OUTPUT);\npinMode(C7, OUTPUT);\npinMode(C8, OUTPUT);\npinMode(C9, OUTPUT);\npinMode(C10, OUTPUT);\npinMode(C11, OUTPUT);\npinMode(C12, OUTPUT);\npinMode(C13, OUTPUT);\npinMode(C14, OUTPUT);\npinMode(C15, OUTPUT);\npinMode(C16, OUTPUT);\npinMode(C17, OUTPUT);\npinMode(C18, OUTPUT);\npinMode(C19, OUTPUT);\npinMode(C20, OUTPUT);\npinMode(C21, OUTPUT);\npinMode(C22, OUTPUT);\npinMode(C23, OUTPUT);\npinMode(C24, OUTPUT);\npinMode(C25, OUTPUT);\npinMode(C26, OUTPUT);\npinMode(C27, OUTPUT);\npinMode(C28, OUTPUT);\npinMode(C29, OUTPUT);\npinMode(C30, OUTPUT);\npinMode(C31, OUTPUT);\npinMode(C32, OUTPUT);\npinMode(C33, OUTPUT);\npinMode(C34, OUTPUT);\npinMode(C35, OUTPUT);\npinMode(C36, OUTPUT);\npinMode(C37, OUTPUT);\npinMode(C38, OUTPUT);\npinMode(C39, OUTPUT);\npinMode(C40, OUTPUT);\npinMode(C41, OUTPUT);\npinMode(C42, OUTPUT);\npinMode(C43, OUTPUT);\npinMode(C44, OUTPUT);\npinMode(C45, OUTPUT);\npinMode(C46, OUTPUT);\npinMode(C47, OUTPUT);\n}\nvoid loop()\n{\nif (Serial.available() >= 47) {\nfor (int i=0; i<=47; i++)\n{\nincomingByte[i] = Serial.read();\n}\ndigitalWrite(C1, incomingByte[0]);\ndigitalWrite(C2, incomingByte[1]);\ndigitalWrite(C3, incomingByte[2]);\ndigitalWrite(C4, incomingByte[3]);\ndigitalWrite(C5, incomingByte[4]);\ndigitalWrite(C6, incomingByte[5]);\ndigitalWrite(C7, incomingByte[6]);\ndigitalWrite(C8, incomingByte[7]);\ndigitalWrite(C9, incomingByte[8]);\ndigitalWrite(C10, incomingByte[9]);\ndigitalWrite(C11, incomingByte[10]);\ndigitalWrite(C12, incomingByte[11]);\ndigitalWrite(C13, incomingByte[12]);\ndigitalWrite(C14, incomingByte[13]);\ndigitalWrite(C15, incomingByte[14]);\ndigitalWrite(C16, incomingByte[15]);\ndigitalWrite(C17, incomingByte[16]);\ndigitalWrite(C18, incomingByte[17]);\ndigitalWrite(C19, incomingByte[18]);\ndigitalWrite(C20, incomingByte[19]);\ndigitalWrite(C21, incomingByte[20]);\ndigitalWrite(C22, incomingByte[21]);\ndigitalWrite(C23, incomingByte[22]);\ndigitalWrite(C24, incomingByte[23]);\ndigitalWrite(C25, incomingByte[24]);\ndigitalWrite(C26, incomingByte[25]);\ndigitalWrite(C27, incomingByte[26]);\ndigitalWrite(C28, incomingByte[27]);\ndigitalWrite(C29, incomingByte[28]);\ndigitalWrite(C30, incomingByte[29]);\ndigitalWrite(C31, incomingByte[30]);\ndigitalWrite(C32, incomingByte[31]);\ndigitalWrite(C33, incomingByte[32]);\ndigitalWrite(C34, incomingByte[33]);\ndigitalWrite(C35, incomingByte[34]);\ndigitalWrite(C36, incomingByte[35]);\ndigitalWrite(C37, incomingByte[36]);\ndigitalWrite(C38, incomingByte[37]);\ndigitalWrite(C39, incomingByte[38]);\ndigitalWrite(C40, incomingByte[39]);\ndigitalWrite(C41, incomingByte[40]);\ndigitalWrite(C42, incomingByte[41]);\ndigitalWrite(C43, incomingByte[42]);\ndigitalWrite(C44, incomingByte[43]);\ndigitalWrite(C45, incomingByte[44]);\ndigitalWrite(C46, incomingByte[45]);\ndigitalWrite(C47, incomingByte[46]);\n}\n}\n

      All the sketch really says is, listen to serial, take that info and do this. Upload the sketch using the USB cable plugged into your computer. I don't believe you can upload the sketch or make any changes to the sketch using xbee. Once I had this all setup, I built a 47 led array connected to the pins I want to use, plus the xbee. With a 9 volt battery and the Arduino, I tested this setup. My I created a one at a time sequence on my desktop and hit play. Immediately the lights started flashing. I walked away from the desktop antenna and I was able to venture about 100 feet from the antenna and maintain the signal. Everything is looking great.

      \n

      I didn't change a thing with the Arduio and placed it in the box and connected it to the relays. I connected up the DC system and then tested the relays one at a time. This part was fairly amusing, 47 relays clicking is funny for some reason. I also used this time to play with my multimeter, I tested every aspect of the system before moving on. Making sure the set screws worked as claimed and everything was connected correctly. This will be the last time you have easy access to all the hardware so it needs to be verified. The next step is wiring the relays to do work. So lets do some money math real quick. I have 47 channels. Outdoor outlet boxes are only two gang. If you break the tabs off your outlets you can put 4 channels in one outdoor PVC box. Lets say that since you didn't destroy one of your relays you would have 48. 48 divided by 4 is twelve. You need 12 outdoor PVC boxes. At roughly $7 per box at a minimum that cost $84. Then add onto that receptacle covers They generally cost about $14 each. 12 times 14 equals 168 dollars. 84 + 168 = 252 dollars! This doesn't cover the cost of wire, outlets, and PVC fittings. 250 dollars just for molded plastic seems wasteful.

      \n

      Its best practice to go with that method. I simply can not spend the money for that. Instead I went to the dollar store and bought enough green extension cords to complete my task. The extension cords are about 6 foot long. I cut about one third of the cable off of the male side. Since these extension cords are not solid core copper I stripped off a bit of the ends and twisted them before tinning the tips with solder. The relays have set screws and stranded wire doesn't make as nice of a connection as solid wire so by tinning the tips you're giving the screws something to bite onto. In conjunction with the extension cords I used electric glands to pass the wires through the wall of the junction box. I bought 6 of them and randomly divided all 47 extension cords through only 5 of them. The 6th one will be used for main power later on. As I installed the extension cords I labelled and color coordinated the female parts. And also hit it with the multimeter to double check my work. Once all the extension cords have been connected and verified, it's time to install the main power. In my junk pile I had about eight feet of 14/3 outdoor romex. I color coordinated both of these to indicate which one is A and B. There's nowhere to tie in the ground in this system, so I clipped that end off and then moved on to the white wires. I tied all of the neutrals together and then tested that with a multimeter, testing across the two furthest points ensuring a sure path. I used the same push-in connectors and several hot glue sticks to create a solid brick of push in connectors. Finally I tied the hot black wires into their sides and the system is complete. I ran a live test of the system a few weeks ago. I pulled out a few strings of lights and played around experimenting with the Vixen environment. I have a few ideas on how I would like to change the system but I haven't incorporated these ideas yet. What I would like to do is bring a raspberry pi in to remove my desktop. I found a program on SourceForge called Lumos. The creator claims that his program can play Vixen sequences via the command line in Linux. I would like to give this a try, or just get Vixen to work under Linux. I don't want to dedicate my main computer to perform this yearly task. I hope I have explained this clear enough. I don't participate in all the social media sites, but I do wear tinfoil hats. If you would like to reach me I hangout in the Podnutz Chat on freenode, my user name is Underruner. Thank you for listening.

      \nSigflup calls in a \"off the cuff\" episode about JavaScript from the Hospital. \n

      \n

      \nJavaScript
      \nFrom Wikipedia, the free encyclopedia\n

      \nJavaScript (JS) is an interpreted computer programming language. As part of web browsers, implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed. It has also become common in server-side programming, game development and the creation of desktop applications.
      \nJavaScript is a prototype-based scripting language with dynamic typing and has first-class functions. Its syntax was influenced by C. JavaScript copies many names and naming conventions from Java, but the two languages are otherwise unrelated and have very different semantics. The key design principles within JavaScript are taken from the Self and Scheme programming languages. It is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.
      \nThe application of JavaScript to uses outside of web pages—for example, in PDF documents, site-specific browsers, and desktop widgets—is also significant. Newer and faster JavaScript VMs and frameworks built upon them (notably Node.js) have also increased the popularity of JavaScript for server-side web applications.
      \nJavaScript was formalized in the ECMAScript language standard and is primarily used as part of a web browser (client-side JavaScript). This enables programmatic access to computational objects within a host environment.\n

      Like many people I enjoy listening to music, and having my music with me everywhere is important. And I have a large music collection to draw on. Trying to have everything with me at all times is a bit of a problem, though, considering how much music I have. Right now I own a number of portable MP3 players, two of which are full of music that I carry with me. My pockets can get very full that way, though, and while I like listening to tracks I own, what about finding new stuff? My MP3 players have never suggested anything to me. This is where the cloud services come in.

      \n\n

      \nMetadata in MP3, Opus/Ogg/FLAC/Speex, and other audio files.\n

      \n

      \nToday's episode discusses (and encourages) the use of metadata tags in audio files.\nMost of the episode is spent on id3v2.3 (metadata for mp3 files) and vorbiscomments (metadata for opus, ogg vorbis, flac, and speex files), and how to mix them, though metadata in webm/matroska, windows media, and wav files is briefly discussed as well.\n

      \n

      \nThis episode's files have also been crafted with substantially more metadata than the ID3v1 set of tags that HPR normally limits itself to, to serve as examples.\n

      \n

      \nListeners to the opus, ogg (vorbis), or speex versions will also have access to chapter markings if your playback software recognizes standard vorbiscomment chapter metadata. (No chapter markings in the mp3, as support for it is extremely sparse, and I've not\nyet even managed to find a tool for making mp3 chapters that actually works - the java utility I mention in the episode crashes on me without starting...)\n

      \n

      \nAll metadata conforms to the published standards, so your playback software should at best fully use it all, or at worst simply ignore it. If your player software actually DOES have a real problem with this file, I would very much like to know!\n

      \n

      \nIf there's anything wrong with the metadata, blame Epicanis, not HPR (I did the metadata myself).\n

      \n

      \nIf you hear or see any errors in this episode, please tell me. I'll issue appropriate corrections in subsequent episodes. If I'm a big enough screwup with this episode, I could even do a small episode on \"everything I got wrong in my metadata episode\" if I did\nbadly enough. I don't THINK there should be more than a few minor errors or omissions here, though.\n

      \n

      \nERRATA: In chapter 18 (at 34:53) there is one small error: oggenc does NOT transfer attached pictures from flac input (though it DOES transfer all vorbiscomment metadata. FLAC stores attached pictures in a separate metadata structure so oggenc misses it.\nopusenc - at least in recent beta versions - DOES appear to transfer the attached pictures as well as the vorbiscomments, though. Another reason to upgrade to opus, I suppose...)\n

      A show about batteries - Part 1

      \n

      I can't take the credit for all this detailed information in my podcast, I found this fantastic website many years ago while investigating why the battery in my expensive razor prematurely failed. I tried to hunt for the site but couldn't find it. I wrote up all my notes from memory and recorded the show. It wasn't until I started working on part 2 of my batteries show that I stumbled across this long forgotten site - at least I think it's the same one as it talks about the memory effect on satellites and doctor's pagers so I guess it must be the same one. I'm indeed delighted to find it still exists, and I may very well read it again from top to bottom. It looks like it's been updated a little too. Well done ka7oei a fantastic resource right enough.

      Two Possible Chargers (For use in the UK)

      \n

      I found it very difficult to find a slow trickle charger, here are two possibilities, you may need to settle for a fast charger as the slow ones now seem to be like hen's teeth, (VERY HARD TO GET).

      \n

      This is perhaps a little slow with a charge current of only 150ma, would take about 17Hrs to charge 2100 mAh batteries.

      \n

      \n

      The charger I use is made by the same company as this although mine is a different model. My model charges at 200ma, and takes about 13 Hrs to charge a 2100 mAh battery. I can't tell what charge current this charger deliveries, but suspect it's a simple slow charger, probably old stock, as I said slow chargers are getting like hen's teeth.

      Today on Hacker Public Radio, we will talk about old games, and interview an expert from Sweden.

      \"GamingGrannar\" and \"Spelklassiker Musik\"

      \n

      In 2012, the Swedish gaming community \"Level 7\" voted for the blog Gaminggrannar to become \"Gaming Blog of the year\". Gaminggrannar (or \"Gaming Neighbours\") consists of David \"Dave\" Boström, Emelie \"Ekken\" Karlsson and Andreas \"hiro\" Karlsson.

      \n

      Dave won the Swedish Championship in Nintendo, in 2003, and has a great Metroid collection. Ekken is an acomplished gamer, creates edible game cakes and also has a newly started collection of games with pink cartridges. hiro can be recognized by his retro game inspired tatoos, and is known for his love for series like Mega Man X and Castlevania.

      \n

      Together the three neighbours release a video blog about everything and anything gaming related, but often with a focus on older games.

      \n

      The podcast that hiro hosts together with Tobias Jensen, a NES and Amiga 500 gamer who wished he had more time for games, hit the 200th episode in november 2013.

      \n

      Retrospelsmässan

      \n

      hiro and I met at Retrospelsmässan 2013. This retro game convention is on its fourth year, and has grown considerably. Now in the second largest exhibition hall in Gothenburg, with roughly 2.000 visitors, and a three hour queue to get in. Competitions in old games, buy retrogames and consoles, cosplay competition, and so on. \"Retrospelsmässan is a yearly event with focus on consoles and computers that was released before the year 2000.\" -- Markus Swerlander, one of the organisers.

      \n

      The date for the 2014 edition of Retrospelsmässan is already set, saturday the 3rd of may in Eriksbergshallen, Gothenburg.

      My username is hobbybob there, so if you have any questions just ask me in a pm. It is good habit that you introduce yourself on the forum, this will get you more credits when you start asking questions. Just introduce yourself, what you want to built and what you already have done/tried in the past.

      \n

      Ohh and BTW i sound a bit dull because i was very tired. As the Light team, we worked from 9AM to 3AM every day during OHM to make the experience a colorful one for everyone!

      \n

      We hope you enjoy(ed) our effort and start building cool stuff yourself !

      \n

      If you want to make your own LOC controllers, LED effects or Lasers i am very interested to know. You can mail me: hobbybob at bitlair dot nl

      \"There's no reasons to use MySQL anymore.\"
      -- Monty

      \n

      Michael Widenius at FSCONS 2013

      \n

      A couple of months ago I attended FSCONS 2013. There I met Michael \"Monty\" Widenius, the driving force behind both MySQL and MariaDB. This is a guy who loves being a developer and he loves Open Source software. He named MySQL after his daughter My, and the new fork MariaDB got its name from his other daughter Maria.

      \n

      Monty was invited to FSCONS 2013 to give a speech entitled \"The MySQL and MariaDB story\", and the synopsis on fscons.org says:

      \n
      \"The story of how MySQL was created, why it was successful and how it grew until it was sold to Sun, who was then overtaken by Oracle.
      It will also cover how and why MariaDB was created and what we are doing to ensure that there will always be a free version of MySQL (under the name of MariaDB).
      The talk will also explain the challenges we have had to do this fork, especially the merge with MySQL 5.5, and the various systems (like buildbot) that we used to build the binaries and how we are working with the MariaDB/MySQL community.\"
      \n
      -- https://frab.fscons.org/en/fscons13/public/events/51

      That presentation can be found on YouTube, and I encourage you all to have a look at it. \"Michael Monty Widenius: The MySQL and MariaDB story\": https://youtu.be/JxyBNdwmpzM
      \n

      \n

      If you have not yet made the switch to MariaDB, now is the time!

      \n

      Monty also asks everyone who uses MariaDB to activate the anonymous plug-in, so that the developers might know what to focus their attention on.

      \n

      If you wish to look Monty in the eyes, you have the opportunity to do so, as this interview was video recorded and will be released on YouTube or similar. Follow All In IT Radio on Google+, Twitter and Identi.ca for updates on when that will be released.

      \nThis Episode is kind of a direct response to HPR1343 by Laindir, where he explains his awesome way to decode the morse code in HPR1216. For the fun of it, I start right out by digressing into a memory of mine. It is about how I tried to decode morse code telemetry from the AO-21 amateur radio satellite some 20 years ago by using a CBM-8032 computer. \n

      \n

      \nAfter that I reveal the easy way to decode HPR1216 by using the CW mode of the program FLDIGI. Along the way, I mention the use of \"monitors\" in pulse audio, which are selectable in pavucontrol as input sources for audio applications. This is an easy way to loop back sound output from other applications. This method also combines nicely with WEBSDR, web accessible software defined receivers, all over the world. These may be used if you want to throw some real world signals at FLDIGI to play with the different modes. For listening to amateur radio communication I recommend to start out with one of these modes: CW (morse telegraphy), PSK > BPSK31 (very common, narrow band tele type mode) and RTTY > RTTY-45 (\"original\" radio tele type). For the typing modes you might want to check also \"View>Waterfall>Docked scope\" or activate \"View>View/Hide Channels\".\n

      \n

      \nFinally I add a tip about using OSS-wrappers like aoss, from alsa-oss, and padsp from the pulseaudio-utils package, to run old OSS applications. I use this primarily for siggen, a suit of command line / curses applications for generating audio signals like sine wave, rectangle and so on. \n

      \n

      \nNOTE: There is one stumbling block with pavucontrol, which I forgot to mention in the recording. Applications will only show up as playback sources or recording sinks when they actively use the interface. That is, the alsa player source will only be visible while playing, in the same way as an audacity sink can only be seen while the recording is going on. \n

      Coffee Stain Studios

      \n

      In 2010 a few students from the University of Skövde created the Indie game developing company \"Coffee Stain Studios\". In 2011 they released the game \"Sanctum\" on Steam, and in May of 2013 they released \"Sanctum 2\". These games are most often described as a mix between First-person shooter and Tower defense. You find yourself in a futuristic setting, fighting aliens with a fair bit of humor. The player chooses how much resources to distribute on automatic towers or his or her own weapons. Both games featured the possibility to collaborate with your friends to beat the levels.

      \n

      One of the founders, Armin Ibrisagic, was at DreamHack in November 2013, where I got a chance to talk to him.

      \n

      DreamHack

      \n

      \"What is DreamHack?\" you ask? Only the world's largest computer festival, held multiple times a year in Jönköping, Sweden. According to Wikipedia \"It holds the world record (as recognized by the Guinness Book of Records and Twin Galaxies) for the world's largest LAN party and computer festival, and has held the record for the world's fastest Internet connection, and the record in most generated traffic.\"

      \n

      I also got an interview with one of the organizers of DreamHack, but that you will hear another day. Today we focus on Sanctum, and how the market looks for smaller game developers.

      Please consider recording an episode for Hacker Public Radio. We are a you-contribute podcast. :)

      \n

      Ken requests an episode on Fahrenheit, which really requires discussion of the two temperature systems, and how they are quantified.

      \n

      Terminology

      \n

      Centigrade: old fashioned term for Celsius
      Kelvin (K): less common measurement of temperature used for Science
      Thermal Equilibrium: en.wikipedia.org/wiki/Thermodynamic_equilibrium
      Zeroth Law of Thermodynamics: en.wikipedia.org/wiki/Zeroth_law_of_thermodynamics
      Absolute zero: en.wikipedia.org/wiki/Absolute_zero
      \n

      \n

      My personal preference is Celsius. Less numbers to deal with in everyday use.
      Really Cold – Temperatures below 0°C
      Really Hot – Temperatures above 30°C
      The \"American\" thinking is temperatures go in 20's, 30's, 40's...etc. more work!
      Obligatory gun discussion
      Indirect conversation about PV = nRT formula
      Correction: the absence of pressure (vacuum) causes water to boil.
      Celsius and Fahrenheit are \"measured\" by the states of water boiling/freezing.
      \n 

      \nCelsius\nfreezes at 0°\nboils at 100°\n\nFahrenheit\nfreezes at 32\nboils 212°\n\n1 (K) Kelvin = -273.15°C\n

      LibreOffice Writer Other Frame Styles

      \n

      In the previous tutorial we looked at using the frame style for text, which is not called the Text style, but the Frame style, which may be confusing. This is a very common use of frames, but there are others. To start the discussion, let’s get back to the basic concept of objects. LibreOffice is an object-oriented program and you should keep this in mind when dealing with this software.

      \n

      A piece of text can be an object, and it can contain other objects (paragraphs, sentences, words, characters), or it can be contained within other objects (section, chapter, document). In the case we are looking at, a frame is an object, which contains other objects, and is in turn contained within larger objects (page, section, document). Depending on the objects being contained, the frame styles can be different, and that is what we need to look at now.

      \n
      \nA Libre Graphics Magazine is long overdue. In a market dominated by magazines devoted to design discourse built around proprietary tools and the latest computer graphics tricks and techniques, users of Libre Graphics software are underserved and unrecognized. We know that these users exist, both professionally and as hobbyists. We know this because we are they. We are graphic designers, media artists, photographers and web designers. We use Libre Graphics software, quietly and without regard. Our peers, used to proprietary alternatives, question our choice of tools. Our work, when executed well, is indistinguishable from work produced by more traditional means. Thus, our choices are invisible, unless we make an issue of them.\n

      \nDebian developer and T-Shirt salesman, Joost van Baal-Ilić takes some time away from the booth to give us the run down on Debian.\n

      \n
      \nThe Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system that we have created is called Debian.\n\nAn operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer and does all the basic housekeeping and lets you start other programs.\n\nDebian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.\n

      HelenOS Screen Shot

      \n\n
      \nHelenOS is an operating system based on a multiserver microkernel design. Rather sooner than later, HelenOS will become a complete and usable modern operating system, offering room for experimenting and research. HelenOS uses its own microkernel written from scratch and supports SMP, multitasking and multithreading on both 32-bit and 64-bit, little-endian and big-endian processor architectures, among which are AMD64/EM64T (x86-64), ARM, IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC and SPARC V9. Thanks to the relatively high number of supported architectures and suitable design, HelenOS is very portable. On top of the microkernel, HelenOS provides services such as file systems, networking, device drivers and user interface. Most of these services are composed of multiple independent server processes, which makes HelenOS one of the most modular operating systems.\n

      \nI took Michael Tänzer away from checking passports and drivers licenses to explain to us what's the idea behind CACert.org\n

      \n
      \nCAcert.org is a community driven Certificate Authority that issues certificates to the public at large for free. CAcert's goal is to promote awareness and education on computer security through the use of encryption, specifically with the X.509 family of standards. We have compiled a document base (Wiki) that has helpful hints and tips on setting up encryption with common software, and general information about Public Key Infrastructures (PKI). CAcert Inc. is a non-profit association, incorporated in New South Wales, Australia.\n

Based on past experience I'm more inclined to blame the operator than the device so the audio is taken from the backup recording device, a Sansa Clip.

      00:27:07 KDE

      \n

      \nOver at the KDE booth, I managed to track down Jonathan Riddell about the KDE project. From Wikipedia:\n

      \n
      \nKDE is an international free software community producing an integrated set of cross-platform applications designed to run on Linux, FreeBSD, Solaris, Microsoft Windows, and OS X systems. It is known for its Plasma Desktop, a desktop environment provided as the default working environment on many Linux distributions, such as openSUSE, Mageia and Kubuntu and is default desktop environment on PC-BSD a BSD operating system.
      \n\nThe goal of the community is to provide basic desktop functions and applications for daily needs as well as tools and documentation for developers to write stand-alone applications for the system. In this regard, the KDE project serves as an umbrella project for many standalone applications and smaller projects that are based on KDE technology. These include Calligra Suite, digiKam, Rekonq, K3b, and many others.
      \n\nKDE software is based on the Qt framework. The original GPL version of this toolkit only existed for the X11 platform, but with the release of Qt 4, LGPL versions are available for all platforms. This allows KDE software based on Qt 4 to also be distributed to Microsoft Windows and OS X.\n
      \n

      \nAbout KDE\n

      \n
      \nThe KDE Community is an international technology team dedicated to creating a free and user-friendly computing experience, offering an advanced graphical desktop, a wide variety of applications for communication, work, education and entertainment and a platform to easily build new applications upon. We have a strong focus on finding innovative solutions to old and new problems, creating a vibrant atmosphere open for experimentation.\n

      \nDaniel Lobato and Doran Fedu help me understand what Foreman, oVirt, and OpenStack is all about.\n

      \n

      Foreman

      \n
      \nForeman is an open source project that gives system administrators the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage servers, on-premises or in the cloud. (From Wikipedia) Foreman (also known as The Foreman) is a complete life cycle systems management tool for physical and virtual servers with deep integration to configuration management software, specifically Puppet. The Foreman provides provisioning on bare-metal (through managed DHCP, DNS, TFTP, and PXE-based unattended installations), virtualization and cloud. The Foreman provides comprehensive, auditable interaction facilities including a web frontend, command line interface and robust, REST API.\n
      \n

      oVirt

      \n
      \noVirt manages virtual machines, storage and virtualized networks. (From Wikipedia) oVirt is a free platform virtualization management web application community project started by Red Hat. oVirt is built on libvirt which could allow it to manage virtual machines hosted on any supported backend, including KVM, Xen and VirtualBox. However, oVirt is currently focused on KVM alone. oVirt is an open source software with backing from Red Hat and it is the base for Red Hat Enterprise Virtualization.\n
      \n

      OpenStack

      \n
      \nOpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.\n

      The Pandora is a handheld game console designed to take advantage of existing open source software and to be a target for homebrew development.

      \n

      Over at the Puppet booth we talk to Eric Sorenson from PuppetLabs and Bert Van Vreckem from the Belgium Puppet user group.

      \n
      Puppet Open Source is a flexible, customizable framework available under the Apache 2.0 license designed to help system administrators automate the many repetitive tasks they regularly perform. As a declarative, model-based approach to IT automation, it lets you define the desired state - or the “what” - of your infrastructure using the Puppet configuration language. Once these configurations are deployed, Puppet automatically installs the necessary packages and starts the related services, and then regularly enforces the desired state. In automating the mundane, Puppet frees you to work on more challenging projects with higher business impact. Puppet Open Source is the underlying technology for Puppet Enterprise and runs on all major Linux distributions, major Unix platforms like Solaris, HP-UX, and AIX, and Microsoft Windows.

      Other Page Layout Options

      \n

      As we mentioned in beginning our look at Page Layout, you have some options other than just Page Styles and Frame Styles, useful though they are. So let’s spend a few moments looking at these other options and see how they work.

      \n

      Tables

      \n

      Tables can be a useful tool for more than just displaying tabular data. You can place different object in each cell of a table and so have some control over how things are laid out on the page. You could, for instance, place your sub-heads in a left-hand column, and the associated text in an adjoining column, which gives you the same effect as using the Marginalia style. And you can add pictures, charts, and other objects as well. You can even insert a table into a cell of another table to get more fine-grained control. In fact, in the days before Cascading Style Sheets and Javascript, tables were the primary way of laying out Web pages, though these days that is frowned upon, and in any case most Web pages are now created using some kind of CMS software like WordPress, or Drupal. The idea of using tables was more attractive when we realized you could turn-off the cell borders and make them invisible. Of course, in Writer documents that only works when they are printed. When opened on a computer the table borders are still visible, as indeed they would have to be for you to edit the document.

      FSCONS 2012: \"Open animation projects: state of the art, problems and perspectives\"

      \n

      We all know of the Blender Projects, like Elephants Dream, Big Buck Bunny and Sintel, but do you know of any more? Creating an animated movie is hard. Many enthusiasts start projects up that soon thereafter unfortunately die off.

      \n

      The state of this area of interest is what Julia Velkova has concentrated her research on. At FSCONS 2012 she gave the first part of a presentation, painting a picture of the state of matters, then followed by open animator Konstantin Dimitriev who introduced both the Morevna Project and the free and open source tool Synfig Studio.

      \n

      At this presentation Konstantin showed the premiere trailer for his animé movie \"The Beautiful Queen Marya Morevna\", a modernized version of a traditional Russian tale. Both the trailer and Julia and Konstantins presentations are available on YouTube.

      \n

      Konstantin has used indiegogo to crowdfund a full time developer for Synfig Studio. He wrote: \"I am mentoring a full-time developer Ivan Mahonin, who is working on Synfig code. We have funded his work in previous months by running similar fundraising campaigns for October, November, December, January and February.\" So go help them with the rest of 2014 as well!

      \n

      Go help the Morevna Project and Synfig Studio, follow both Julia and Konstantin on Twitter to get updates on this very interesting part of the free and open community that I suspect we sometimes might forget.

      \nNow it is time to take a look at practical uses of encryption, and the number one use is for e-mail. Encrypted communication via e-mail is very desirable if you want to keep a secret. In the U.S. the current legal precedents say that any e-mail left on a server is not protected since you would have no expectation of privacy. This precedent was set many years ago when POP3 was the standard for all e-mail and people did not usually leave e-mail on a server. These days, many people use web-based e-mail or use a newer standard called IMAP which by default stores everything on the server. Perhaps you are one of these people, and thought that you had a right to expect privacy, but in the U.S. you dont, and I would expect that in many other countries the situation is no better.\n

      \n

      \nThere have been attempts to provide encrypted e-mail service from a service provider, but the problem here is that the provider usually has to have to the key in order to encrypt the e-mail, and if they have the key they can be compelled to give it up. Recently in the U.S. there was a case involving Ladar Levison who ran such a service called Lavabit. Lavabit encrypted mail in transit using TLS encryption, and he had the keys. When his service was used by Edward Snowden, the government came to get the keys. Now, Levison would have given them the key for Snowdens e-mail if he had been served a warrant, as he always made clear to his customers that he would obey proper legal demands. But in this case the government demanded that he turn over all of the keys for all his customers, and this was too far for Levison. He shut down his service rather than cooperate, and is a bit of a hero for that. But it illustrates that you are at the mercy of the service provider. If the government made this demand to Lavabit, you are safe in presuming they had made the same demand to other providers, and that they all cooperated with the government and said nothing to their customers. So it would be mistake to rely on 3rd party mail service providers to give you privacy. You need to control it yourself. But of course, after the last few lessons you know how to do that, and have your secure keys created. You just need to put them to use.\n

      LibreOffice Calc: What is a Spreadsheet?

      \n

      There are different ways to answer this question. Functionally, spreadsheets are a tool for mathematical calculations, but have branched out into related areas like data analysis. Some people even use them as a quick-and-dirty database tool. If you are in a financial profession of some kind you probably live in spreadsheets all day.

      \n

      Spreadsheets are original “killer app”. Early examples were implemented on mainframe computers in the 1960s, but the big step was the creation of VisiCalc for the Apple II in 1979, which was then ported to the IBM PC in 1981. VisiCalc set the conventions that guided all subsequent spreadsheets, and the essential methods have not changed since then. VisiCalc was called the first killer app because people would buy the computer just to run the program, and the usefulness of spreadsheets is what promoted the initial entry of personal computers into the corporate world, with all of the change that has caused.

      \n\n

      \nIn today's show we continue our look at The OSI model for network communications, with examples of Layer 3 been given with particular focus on Geography diverse Host addressing. \n

      From Wikipedia: https://en.wikipedia.org/wiki/OSI_layer_3

      \n\n

      In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, whereas the data link layer is responsible for media access control, flow control and error checking.

      \n\n

      Functions

      \n

      The network layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination host via one or more networks, while maintaining the quality of service functions.

      \n

      Functions of the network layer include:

      \n
        \n
      • Connection model: connectionless communication
        • \n
      \n
      \n
      For example, IP is connectionless, in that a datagram can travel from a sender to a recipient without the recipient having to send an acknowledgement. Connection-oriented protocols exist at other, higher layers of the OSI model.
      \n
      \n
        \n
      • Host addressing
        • \n
      \n
      \n
      Every host in the network must have a unique address that determines where it is. This address is normally assigned from a hierarchical system. For example, you can be \"Fred Murphy\" to people in your house, \"Fred Murphy, 1 Main Street\" to Dubliners, or \"Fred Murphy, 1 Main Street, Dublin\" to people in Ireland, or \"Fred Murphy, 1 Main Street, Dublin, Ireland\" to people anywhere in the world. On the Internet, addresses are known as Internet Protocol (IP) addresses.
      \n
      \n
        \n
      • Message forwarding
        • \n
      \n
      \n
      Since many networks are partitioned into subnetworks and connect to other networks for wide-area communications, networks use specialized hosts, called gateways or routers, to forward packets between networks. This is also of interest to mobile applications, where a user may move from one location to another, and it must be arranged that his messages follow him. Version 4 of the Internet Protocol (IPv4) was not designed with this feature in mind, although mobility extensions exist. IPv6 has a better designed solution.
      \n
      \n

      Within the service layering semantics of the OSI network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.

      The cost of printing

      \n

      The reason that printers are so affordable is because like game consoles, they are not. They are sold at cost or below cost. The printer manufacturers make their money by selling you replacement ink cartridges that are very expensive. While you can use replacement cartridges, the manufactures will try and dissuade you from using them by displaying messages in the screens to \"alert\" you to the fact, or will include chips in their printers to prevent you from refilling or swapping their cartridges for cheaper alternatives. You should consider a laser printer option as while the toner cartridges are more expensive, even those supplied by the manufacturers work out cheaper over time. But if you wish to use a Ink Jet, then a serious alternative to lower the cost of printing is to use a CISS, Continuous ink supply system.

      \n

      CISS, Continuous ink supply system

      \n

      A CISS, Continuous ink supply system, is a system where you use cheaper non brand ink in your printer, just like you would with replacement no-name brand cartridges. Instead of having to refill the cartridges as they empty you supply them via a thin hose to an external reservoir. The advantage is that you can buy your ink in bulk and refill it without having to open the printer. This brings the cost of printing down considerably.

      1. What Functions would you like ?
        In the Netherlands there is an excellent site called Tweakers.net that allow you to select devices by their features without having to gather all the information from various review sites that may/may not be influenced by outside forces. Although the site is in Dutch it should be fairly obvious what's being asked.
        https://tweakers.net/categorie/922/printers/producten/ (Google Translate version)
        2. \n
      2. Will it work with Linux
        Once you short list the printer(s) you like, head over to https://www.openprinting.org/printers to find out if it's supported by Linux and by extension Mac/iOS. Do this even if you plan to run Windows as it proves that the printer is popular and is likely to be supported.
        3. \n
      3. Will it really work with Linux
        Support is a big word and while it may be trivial for some to recompile a Kernel and X to get the thing working. It saves a lot of time and effort if you look around on the Linux Distributions forums to see if there are reported problems installing the printer. A good search is \"${your printer model number} linux howto\", check the dates on the posts as well paying more attention to the newer ones. Don't worry if you find a HowTo on another distribution than the one you are using as the chances are good that it will also apply to your install.
        4. \n
      4. Can you easily use replacement cartridges ?
        For to answer this, you will need to search in your local stores and on-line to see if there is a popular replacement option available. You should pay particular care to whether the cartridges require a chip or not.
        5. \n
      5. Is there a CISS option
        Now you need to check for a CISS supplier and to see whether they have a supported model for your printer and if there is instruction videos on how to install them
        For my purposes \"City Ink Express\" https://www.cityinkexpress.co.uk/ciss fitted the bill on both counts. They are a UK store and the only purchase I made arrived before the printer I ordered and the ink system seems to work fine.

      Brother MFC-J5910DW

      \n

      I ended up going with the \"Brother MFC-J5910DW\" as we were looking for a printer that could scan to the network, print A3, A4 duplex, as well as supporting Linux. At the time of writing the Brother printers do not use any chips and allow you to replace the cartridges. One annoying thing was that when the ink in one of the supplied cartridges went empty (after printing 10 A3 pages), it no longer allowed me to scan to the network. Fortunately I had the CISS system ready to rock and to be honest I was dreading installing it.

      \n

      Even if you don't want to purchase your CISS system from City Ink Express, you should have a look at their videos. For my printer there were three that were appropriate, namely how to Fill and prime it, how to install it and (for the future) how to refill it. I'm not going to waste time on my experiences as I have nothing to add to the videos other than to say, you may want to put on a pair of gloves and do your work over a news paper to capture any ink that spills.

      \nLast time we looked at how you can use GPG and Enigmail to digitally sign or encrypt messages in Thunderbird. But today many people use web-based mail, and one of the most popular is Googles Gmail. Others include Outlook.com and Yahoo, but using any of them is pretty similar. So since I have a Gmail account handy, I will use that to demonstrate encryption in web mail accounts.\n

      \n

      \nThe important thing you must keep in mind is that this relies on you using your GPG keys to either sign or encrypt the message before it leaves your computer, what Steve Gibson calls Pre-Interent Encryption, or PIE. The flaw in what Lavabit did (discussed in previous lesson) was to use keys that the mail provider controlled, and these keys could be (and were) demanded by the the government.. If you use your own GPG keys that you control, no provider (Google, in this case) is even capable of giving anything to the government other than a blob of random nonsense.\n

      \n

      \nTo do this, I will use an extension for Googles Chrome Browser called Mailvelope. This is also available for Firefox, but in my case I use Chrome to access my Gmail account., so using a Chrome extension makes sense for me. The first thing to do is go to the Chrome store, search for Mailvelope, and install it.\n

      Backup Shows

      \n

      \nIn a discussion started by Dave Morris. Some felt that the content was getting stale, and keeping shows for 2 years or even 3 months was too long. Others felt that these shows were contributed with the purpose of been used in an emergency and therefore should be timeless.
      \nEventually it was left to each of the contributors that had shows in the backup queue to release them, or to set them as emergency shows. The website has been updated to reflect this change.

      LibreOffice Calc: Cells

      \n

      All spreadsheets have the same basic structure, a table of rows and columns. Columns are headed up A, B, C, and so on. After Z, the next column is AA, then AB, AC, AD, and so on. The maximum number of columns is 1024. Rows are numbered 1,2,3 and so on, and the maximum number of rows is 1024*1024, or 1,048,576. At this time I am not aware of any plans to increase these numbers, though that could change if competitive pressures make it necessary.

      \n

      Where a row and column intersect, there is a cell, which is given the address of the column followed by the row, e.g. A1, but never 1A. This is very useful since you can use the contents of a cell in a calculation by simply using the cell address. For example, to add the value of cell B4 to the value in cell C3 and store it, you would write “=B4+C3″ in the cell where you want to store the sum. Learning to use cell addresses is extremely important, so get in the habit of doing this at every opportunity.

      Since the main purpose of a spreadsheet is to perform calculations it is appropriate that we consider just how this is done.

      \n

      In general, a cell of a spreadsheet can contain one of three things:

      \n
        \n
      • A number
        • \n
      • Text
        • \n
      • A formula
        • \n
      \n

      All calculations are done using formulas. A formula occurs whenever a cell has contents that begin with an equals sign, which is the signal to Calc that it needs to perform a calculation. For instance, if a cell contains \"A3+B3\", Calc would examine this, see the letters and the plus sign, and decide that the contents of the cell were a text string. After all, it cannot be a pure number with those other things there. But place an equals sign in front, so that the contents now read \"=A3+B3\" and Calc knows that this is formula, and will perform the calculation. And one of the best ways to interact with a cell that contains a formula is to use the Formula Bar, which normally appears just above the cells of the spreadsheet proper:

      \nHPR Episode: Using and Converting Between Units of Distance\n\nIntro: Last time, we talked in general terms about units, numbers and\nhow they might be useful in practice.  In this episode, we address some\nspecific measurement units that apply to distance and area, and how we\nmight convert from one system to another to better understand both.\n\nEntire point of this episode is this: Carry units in calculations on \n  distances and areas, and you'll have more success in using them in \n  your life.  \n\n\n\nSegment 1:  Distance and Area in the English system\n\n1. Series will focus on English and Metric systems.\n   a. Basic units of distance: inch, foot, yard, mile\n   b. Basic units of area: square inch, square foot, acre, square mile\n\n\n2. Other units of distance and area do exist\n   a. Barleycorn for shoe sizes (1/3\")\n   b. Hand for describing horses (4\")\n   c. Rod for surveying (16-1/2 feet)\n   d. Chain, also for surveying (4 linear rods, 66 feet, 22 yards)\n   e. Furlong from horse racing and agriculture (220 yards, 10 chains)\n   f. League (about an hour's walk) usually assumed to be 3 miles\n      - Nautical: technical unit that's exactly 3 knots\n   g. Square yard may be used in quotes for carpet installations\n\nTable of Units: https://www.csgnetwork.com/converttable.html\n\n\nBrilliant Insight #1: Units of distance were originally arbitrary.  We \n  did not standardize on inches, feet, miles, and so on because these \n  are magical units with special merits.  They were convenient at the \n  time and place where they were invented. \n  \n  Standards let us talk to each other about distance without having to \n  be in the same place at the same time.  We'd have trouble if builders\n  builders had to ask for boards \"as long as my arm\", or a plank \n  that's \"Yea long\". \n\n\n3. Bizarre properties of some English units explained:\n\n   a. Rod/Chain: Used in measuring farmland and building plots\n      - Rod is 5-1/2 yards, or 16-1/2 feet.\n      - Chain is 4 linear rods, or the length of a surveyor's chain\n      - Could have been longer or shorter.  Standard emerged from usage.\n      \n   b. Furlong: Longest row you can plow without resting the animals\n      - Defined as 10 chains (220 yards)\n      \n   c. Acre: If you are on a quiz show, it's 43,560 square feet.  Huh?\n      - Defined as the area of a plot that's 1 chain wide by a furlong \n      - Putting definitions together, we peek ahead to make sense of it.\n      \n        1 acre = 1 chain x 1 furlong x 10 chains   <--- multiply by 1\n                                       ----------       (1 furlong is \n\t\t                       1 furlong         10 chains)\n      \n        Cancelling out furlongs upstairs and downstairs, we get\n\t\n            1 acre = 1 chain x 10 chains = 10 \"square chains\"\n      \n      - So the square feet in an acre is not (completely) arbitrary\n      - It's just mostly arbitrary, but consistent with shorter units.\n\n   d. Mile: Why is it 5,280 feet?  Similar story [Simplified version!]\n      - Roman occupation brought in a 5,000 foot mile (\"mille passus\")\n        Warning!  The Roman mile was defined in Roman feet, so it was\n           a bit shorter than I've painted it.  \n      \n      - Originated as 1,000 double-steps or \"paces\"\n      - Since 1,000 was \"mille\", unit naturally became \"mile\" in English\n      \n      - Elizabeth I (1603, or was it 1593?): \n        * Statute mile set to 8 furlongs (1,760 yds; 5,280 ft)\n        * Why 8 furlongs?  Why not 10 furlongs?\n\n        * Goal: Set new mile close to existing mile, but as N furlongs.\n\t    * New \"statute mile\" only about 5% longer than Roman mile\n\t      Note: Similar analysis could be used with other \"miles\".\n\t      \n\t    * Setting a mile to a even multiple of a furlong had practical \n\t        benefits, and keeping it close to the old unit reduced \n\t        conversion costs for \"legacy users\".\n\t        \n      - That's why we've inherited a mile that measures 5,280 feet.\n\n   To see why the story is tremendously more complicated than my account\n      https://en.wikipedia.com/wiki/Mile\n\n   Fun article on the mile.\n      https://www.sizes.com/units/mile.htm\n   \n   High school student theme on the furlong.\n      https://www.writework.com/essay/history-furlong by silverAlex2000\n\n   Brief dictionary article on the mile, referenced by Dr. Math \n      https://www.unc.edu/~rowlett/units/dictM.html#mile \n      Referred by https://mathforum.org/library/drmath/view/61126.html\n\n   Resource: StackExchange Physics and Maths sections (\"mile\" question)\n      https://physics.stackexchange.com/questions/57785/difference-between-nautical-and-terrestrial-miles\n\n\n4. Converting between units\n   a. Units of distance usually defined as multiples of each other\n      - 1 mile = 5,280 feet            - 1 hand = 4 inches\n      - 1 foot = 12 inches             - 1 yard = 36 inches\n      \n      Skipping ahead to look at the metric system, we now have:\n      - 1 inch = 2.54 centimeters (exact). Regularized in recent years.\n\n   b. This works because there's consensus on Zero distance, so we don't\n         have to adjust for differing origins, as we do with the \n         non-absolute temperature scales like Fahrenheit and Celsius. \n      \n      - We'll get to temperature, non-absolute scales in a later show.\n\n   c. For absolute scales, we can convert from one unit to another using\n         a \"conversion factor\".  That is, we can convert a measurement \n         expressed in one unit to its equivalent in another unit by \n         multiplying or dividing by some number to stretch or compress \n         the original unit to match the target unit.\n\t \n      - Example: I know that 1 foot is 12 inches, so how many inches are\n          there in 10 feet?  How feet are there in 660 inches?\n      \n      - It is clear that a factor of 12 ought to be involved, but how do\n          I know when to multiply or divide by 12 in the conversion?\n      \n      - Wait!  I'm serious.  When you see this problem for the first \n          time, you have to think this through to get it right.  \n        * Without a system in place, you always have to think about it.\n      \n      - Answers in naive setup:\n          (i) 10 feet = (12 * 10) inches = 120 inches\n         (ii) 660 inches = (660 / 12) feet = 55 feet\n\n5. Having a system.  Or units conversion as \"multiplying by One\"\n   \n   a. In each of the solutions I wrote down above, I start with an \n         equation that looks like this: X inches = Y feet.\n\n   b. Inches are not feet, and this way of writing down the calculation \n        does NOT help you figure you how the conversions should work, or\n        whether you should multiply or divide to get the right answers.\n\n   c. Here's a system for creating conversion factors that tell you what\n        to do at each step in the units conversion process.  It is based\n        on the very obvious fact that when I multiply any number by '1',\n        its value remains unchanged.\n\t\n      - Start with one of the identities we wrote down at the beginning.\n\t    In this case, let's use:  12 inches = 1 foot\n\t  \n      - If I divide equals by equals, the results are equal.\n\t    So I can write:\n\t  \n\t                                   12 inches      1 foot\n\t  12 inches = 1 foot implies that  ---------  =  --------- = 1\n\t\t\t\t\t     1 foot      12 inches\n      \n      -\tGet the first term by dividing my original identity by (1 foot).\n      - Get the second term by dividing my original identity by (12 in).\n\n\n   d. To make a conversion from feet to inches, I use:\n   \n\t\t\t   12 in    10 ft \n      10 ft * 1 = 10 ft * ------- = ------ * 12 in = 10 * 12 in = 120 in\n                           1 ft      1 ft\n      \n      - Note: In the fraction (10 ft) / (1 ft), the units \"cancel out\", \n                which leaves a unitless number.\n\t      \n      - Suppose we start with the other form for the conversion factor:\n   \n\t                       1 ft    10 square feet \n      10 feet * 1 = 10 feet * ------ = -------------- = ???\n                              12 in       12 inches\n      \n      - See?  When I use the form where the units don't cancel each \n          other, I get a resulting equation that is still correct.  It \n          just doesn't make much sense to me as a reader.\n      \n      - This is what you get when you \"divide by 12\" to convert feet to \n          inches, but the difference is that you KNOW something's wrong.  \n      \n      - You do not have to even look at the numbers to know that this \n         could not possibly be the right number of inches in 10 feet.\n\n\nBrilliant Insight #2: When you use unit conversion factors, you help \n  your cause by carrying along both sets of units in the form of a \n  fraction as you go through your calculation.  \n  \n  - If the units on the right-hand side of your final equation don't \n    match the units you want (after everything else cancels out), your \n    numerical answer is almost certainly WRONG.\n  \n  - The implication here?  To convert units of distance, you need to \n       multiply or divide by a \n       \n       conversion factor = (X New_Units) / (Y Old_Units).  \n       \n    When you do this, write the conversion factor in its full fractional\n       form, and carry out all of the multiplications and cancellations.\n  \n  - If you do the conversion this way, and the units match, you only \n       have to check your arithmetic to be sure you've got it right.\n\n  - If the units you want do not match those on the right side of the \n       equal sign, you are solving the wrong problem.  The equation may \n       be correct, but it is not expressed in the units you wanted.\n\n\n 6. Let's use the system to solve the second example:\n  \n                               1 ft       660 in * 1 ft \n      660 in * 1 =  660 in *  -------  = --------------- = 55 feet\n                               12 in        12 in\n \n      Why?  The \"inches\" units cancel out because they appear in both \n        numerator and denominator (top/bottom, upstairs/downstairs) of\n\t    the fraction in the next to last term, leaving only \"feet\".\n\n  Why people hate units and conversion problems:\n  https://www.regentsprep.org/regents/math/algebra/am2/leseng.htm\n\n  Comment: The \"algebraic\" approach suggested here is ugly, ad hoc in\n    nature, and unnecessarily complicated.  Forget about setting up\n    equations and going through formal operations to solve them.\n    \n    Choose your conversion factors so that the units work out properly\n    as a straight multiplication problem with cancellation of all the\n    units you don't want.  You may have to \"divide\" numbers, but you\n    can use your calculator for working through the numbers.\n    \n  Cranky Summary: You should not have to solve equations to convert\n    between units. Phooey on anyone who says otherwise. :-)\n \n\nSegment 2: Conversions using compound conversion factors.\n\n1. Suppose I want to find the number of inches in a furlong, or the \n   number of acres (or hectares) in a square mile?\n   \n   - My almanac doesn't carry these conversion factors, so I start with \n       what I do have and work my way through it.\n       \n                                       4 rods    16.5 ft    12 in\n   1 furlong = 10 chains = 10 chains * ------- * ------- * -------\n                                       1 chain    1 rod      1 ft\n\t\n\t     = 10 * 4 * 16.5 * 12 inches = ... = 7920 inches \n\n\n2. For acres in a square mile (1 mi^2), we have a bit more to do.\n\n     Abbreviations used: miles = mi, furlong = fur, chain = ch\n     \n     Area means that we are dealing in two dimensions, so we have to \n        convert the lengths in each dimension.  An acre is already a \n        measure of area, so we're good.\n\t\n                       1 acre    10 ch    8 fur   10 ch   8 fur\n   1 sq mi = 1 mi^2 * -------- * ------ * ----- * ----- * -----\n                       10 ch^2   1 fur    1 mi    1 fur   1 mi\n\t\t      \n\t   = (1 mi * 1 mi) * 1 acre * 10 ch * 10 ch   8 fur * 8 fur\n\t                              ------------- * -------------\n\t\t\t\t\t10 ch * ch     1 mi * 1 mi\n     \n   Units cancel, leaving this:\n   \n   1 sq mi = 1 acre * (100/10) * (8 * 8) = 10 * 64 acres = 640 acres\n  \n   \nNext time:  \"Hey!

      \nThis guide will walk you through setting up an OpenVPN server as well as a client.\n

      \n

      OpenVPN Server Setup

      \n

      \nHere is how to install OpenVPN on Centos6. Other RedHat derivatives should be similar.\n

      \n

      \n

      \n    wget https://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm\n    rpm -Uvh epel-release-6-8.noarch.rpm\n    yum install openvpn -y\n
      \n

      \n

      \nHere is how to install OpenVPN on a Debian server. Other Debian derivatives should be similar.\n

      \n

      \n

      \n    apt-get install openvpn\n
      \n

      \n

      \nAfter the server is installed, the server certificate authority and keys must be generated.\nThis will be followed by the client keys, and then the server configuration file.\n

      \n

      \nCopy the easy-rsa scripts into /etc/openvpn\n

      \n

      \n

      \n    cp -rf /usr/share/doc/openvpn/examples/easy-rsa/2.0/* /etc/openvpn/easy-rsa  # on Debian\n
      \n
      \n    cp -rf /usr/share/openvpn/easy-rsa/2.0/* /etc/openvpn/easy-rsa  # on Centos6\n
      \n

      \n

      \nSet Environmental variables\n

      \n

      \n

      \n    cd /etc/openvpn/easy-rsa\n    vim vars\n
      \n

      \n

      \nChange the following variables to meet your needs. These are used for your\nconvenience. They will be used as the defaults during the interactive key\ngeneration session to set the keys attributes.\n

      \n

      \n

      \n    export KEY_COUNTRY=\"US\"\n    export KEY_PROVINCE=\"CA\"\n    export KEY_CITY=\"SanFrancisco\"\n    export KEY_ORG=\"Fort-Funston\"\n    export KEY_EMAIL=\"me@myhost.mydomain\"\n
      \n

      \n

      \nSource the variables to the current shell\n

      \n

      \n . ./vars\n

      \n

      \nCreate certificate authority\n

      \n

      \n

      \n    ./clean-all\n    ./build-ca\n    ./build-dh\n
      \n

      \n

      \nCreate keys for the server and clients\n

      \n

      \n

      \n    ./build-key-server server\n    ./build-key client1\n    ./build-key client2\n
      \n

      \n

      \nSetup the server configuration file\n

      \n

      \n

      \n  cd /etc/openvpn\n  gunzip /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz  # on Debian\n  vim /etc/openvpn/server.conf\n
      \n

      \n

      \nServer settings\n

      \n

      \n

      \n    port 1194\n    proto udp\n    dev tun\n    ca     /etc/openvpn/easy-rsa/keys/ca.crt\n    cert   /etc/openvpn/easy-rsa/keys/server.crt\n    key    /etc/openvpn/easy-rsa/keys/server.key\n    dh     /etc/openvpn/easy-rsa/keys/dh2048.pem\n    server 10.10.42.0 255.255.255.0\n    ifconfig-pool-persist ipp.txt\n    client-config-dir ccd\n    route 10.10.42.0 255.255.255.0\n    client-to-client\n    keepalive 10 120\n    cipher AES-256-CBC   # AES\n    comp-lzo\n    user nobody\n    group nogroup\n    persist-key\n    persist-tun\n    status openvpn-status.log\n    verb 3\n
      \n

      \n

      \nRestart VPN Service\n

      \n

      \n

      \n    service openvpn restart\n
      \n

      \n

      \nIf the service fails to start, try starting openVPN manually.\nThe resulting errors will allow you to see what item in the\nconfiguration file is incorrect.\n

      \n

      \n

      \n    openvpen server.conf\n
      \n

      \n

      \nOnce you are able to get openVPN to start without error,\nkill it and restart it using the service command above.\nYou can verify that the vpn is successfully running by\nlooking at the configured interfaces using the following\ncommand.\n

      \n

      \n

      \n    ifconfig\n
      \n

      \n

      \nYou should now see an entry like the following:\n

      \n

      \n

      \ntun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00\n          inet addr:10.10.42.1  P-t-P:10.10.42.2  Mask:255.255.255.255\n          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1\n          RX packets:622255 errors:0 dropped:0 overruns:0 frame:0\n          TX packets:986993 errors:0 dropped:0 overruns:0 carrier:0\n          collisions:0 txqueuelen:100\n          RX bytes:40649523 (38.7 MiB)  TX bytes:1344026670 (1.2 GiB)\n
      \n

      \n

      OpenVPN Client Setup

      \n

      \nThe installation of OpenVPN for linux is the same as described above for\nthe server. For Windows, Download and run the OpenVPN installer from the\nOpenVPN Community Downloads.\n

      \n

      \nNOTE: On Windows, User Account Control (UAC) must be turned\noff in order to allow OpenVPN to execute the necessary network\ncommands to bring up the VPN. Open Start > Control Panel >\nUser Accounts and Family Safety > User Accounts > Change User\nAccount Control Settings. Set to Never Notify, click OK,\nand reboot the machine.\n

      \n

      \nClient Configuration file\n

      \n

      \nFor linux, the client config file would go in `/etc/openvpn` just like\nthe server config. We will name it `client.conf` to clarify that the\ndevice is being configured as an OpenVPN client.\nOn Windows, the keys and client config files go in the\n`C:\\Program Files (x86)\\OpenVPN\\config`. The config file has\nto have an `.ovpn` suffix.\n

      \n

      \n

      \n    client\n    dev tun\n    proto udp\n    remote myvpn.example.org 1194\n    resolv-retry infinite\n    nobind\n    user nobody\n    group nogroup\n    persist-key\n    persist-tun\n    ca     /etc/openvpn/keys/ca.crt\n    # on Windows, the format is:\n    # ca \"C:\\\\Program Files (x86)\\\\OpenVPN\\\\config\\\\ca.crt\"\n    # Windows may also change the file suffix on the crt files to cer.\n    # So, If Windows complains that it cannot find the file,\n    # examine its properties to verify the suffix.\n    # The logs are stored at C:\\\\Program Files (x86)\\\\OpenVPN\\\\log\n    cert   /etc/openvpn/keys/client1.crt\n    key    /etc/openvpn/keys/client1.key\n    ns-cert-type server\n    cipher AES-256-CBC\n    comp-lzo\n    verb 3\n
      \n

      \n

      \nCopy client key and server ca files onto client\n

      \n

      \n

      \n    scp  ca.crt  user@client1:.openvpn/\n    scp  client1.crt  user@client1:.openvpn/\n    scp  client1.key  user@client1:.openvpn/\n
      \n

      \n

      \nOn the server create the ccd directory to assign static addresses to clients.\n

      \n

      \n

      \n    mkdir /etc/openvpn/ccd\n
      \n

      \nHPR Episode: How I Got Into Computers\n\n1. Got into computers in 1974 in high school.\n - School had a DEC PDP-11/20 minicomputer\n   * Two ASR-33 Teletype terminals, keypunch, line printer, card sorter\n   * Ran older operating system RSTS-11 v4a\n     - Too low-end to run anything more recent.\n     - 16K words of core memory: point-to-point wired \"cores\"\n\n - The system was somewhat rudimentary.  It's idea of a prompt was:\n \n READY\n \n - A Teletype terminal does not have a screen, so the print head \n     was the only \"cursor\" to let you know where you are. \n \nHardware:\nPDP-11/20: Computer Museum \n  https://www.computerhistory.org/revolution/minicomputers/11/366/1946\n  \nPDP-11/20: Retro Technology\n  https://www.retrotechnology.com/pdp11/exhibit/PDP_11_infoage_1.htm\n\nASR Model 33 Teletype with PDP-11 model computers\n  https://www.retrotechnology.com/pdp11/\n  \nOperating System:\nRSTS-11 System Managers Guide\n  https://bitsavers.trailing-edge.com/pdf/dec/pdp11/rsts/V04/DEC-11-ORSMA-B-D_RSTSmgr_73.pdf\n  \nRSTS-11 System Users Guide\n  https://bitsavers.trailing-edge.com/pdf/dec/pdp11/rsts/V06/DEC-11-ORSUA-D-D_RSTS_SystemUserGuide_Jul75.pdf\n\n\n\n2.

He enabled us to get going with BASIC. \n\n * Anticipated pairs programming by working on programs with a friend as\n    \"Chuck and Duck Enterprises\", but we were mainly having fun.\n   - Started by necessity (1 TTY), but we got satisfying results faster\n   - Both of us could write code, but we learned about using\n       complementary strengths to get cool stuff done.\n\nPairs programming:\n  Pairs Programming, from XP\n  https://www.extremeprogramming.org/rules/pair.html\n  \n  Laurie Williams (Her other stuff is good, too)\n  https://collaboration.csc.ncsu.edu/laurie/publications.html\n\n   \n * Small memory --> innovation\n   - ASCII Art \"Poster\" Program: \n     Create banner with block letters on LP based on terminal input.\n   - Developed a mini-language to encode characters, white space, \n       newlines for each supported character.\n   - This was a special-purpose language used to compress data, rather\n       than a cool Domain-Specific Language (DSL).\n   - We just wanted to make cool banners to come off the line printer.\n\nDomain Specific Languages:  Why ours wasn't a DSL\n  Martin Fowler on DSLs\n  https://martinfowler.com/tags/domain%20specific%20language.html\n  \n\n\n3. Did a math major in college, after switching away from Comp. Sci.\n\n * Math had advantages for me\n   - More flexible curriculum \n   - Abstractions of the time were more fun to play with\n \n * I used the University computers on jobs as research assistant, tutor, typist\n   - Used them in course work, too.\n   - Planning my code carefully let me use my excess CPU seconds for fun\n   - Rule of Thumb: 1 hour in library is worth 12 hours at the terminal.\n\n\n4. Branching out in hardware, systems and programming languages\n\n* We learned FORTRAN in the programming courses\n   - I resisted the temptation to \"think in FORTRAN\" \n   - More general approach felt slower for getting individual jobs done.\n   - Working from first principles seemed more reliable\n   - Often gave me better solutions than following my nose in FORTRAN\n\n   Quirky FORTRAN Preprocessor for Structured Programming (SF/K)\n   https://www.worldcat.org/title/fundamentals-of-structured-programming-using-fortran-with-sfk-and-watfiv-s/oclc/301094243\n\n * Later, I picked up Pascal and TOPS-20 Assembly Language\n   \n   Pascal: From the source\n   Pascal User Manual and Report (Springer)  Trade paperback (1975)\n   by Kathleen Jensen, K Jensen, N Wirth\n\n   Trade paperback, Springer, 1975.

And won in the end.\n   \n   Got paid 3 times minimum wage ($7.50/hour versus $2.30) to look up and read research papers.\n   - I'd have done it for free, so this was a sweet gig.\n   \n   \n * Other jobs:\n   - Tutoring math, computer science for food or cash\n   - Programming jobs\n   - Teaching assistant jobs for statistics, finance courses\n   - Security and management of student-run darkroom in Summer months == \"reading\"\n   - Typing papers on a typewriter\n \n      \n7. After college, started working in non-life insurance.\n\n * End user computing in actuarial group was in BASIC-Plus on PDP-11s\n   - Word processing was in DECword or the WPS-8 dedicated machine.\n   - After first year, moved to department-level PDP-11/44\n   - For heavy-duty jobs, we also had timesharing access to VAX-11/780\n   \n * First project was building a database from mainframe data dump\n   - EBCDIC data conversion to ASCII led to my education about signed\n       data fields in COBOL.\n   - I knew hexadecimal math from my assembly language course\n   - I'd seen EBCDIC in dumps while writing FORTRAN on CP-V\n   \n    Data dumps from 9-track to PDP-11/70 led to Overpunch field conversion\n      https://www.3480-3590-data-conversion.com/article-signed-fields.html\n\n * Note: When you have curly braces at the end of a signed number field, \n     the brace opens in the direction of the positive or negative end of\n     the number line.\n   - Open brace ({): Value ends in zero and has positive sign.  Zero < X\n   - Closing brace (}): Value ends in zero and is negative. Zero > X\n\n * If field ends in A, the value's final digit is 1, and it's positive\n   - B means positive value that ends with a 2, C is 3, ... I is 9.\n   - So \"00003757D\" is $   +375.74.\n   \n * If the field ends in J-R, the value is negative and ends in 1-9.\n   - So \"00000255R\" is the value $   -25.59.\n   \n\n\n8. Irony: I was asked to help troubleshoot a program that was crashing\n     as it was automatically converting the rates and rules manuals away\n     from Unix with 'nroff' to DECword on RSTS in 1982.\n  - This may have delayed my adoption of Linux\n  - Used Unix (Ultrix) in early 1990s to preprocess data for use in OS/2\n  - Had to move to Win 95 and Win NT for work\n\n\n****** Skipping the Dark Period of DOS/Windows and OS/2 Computing ******\n  - Turbo Pascal, APL, PICK, QuickBasic, Visual Basic, Excel with VBA\n  - Learned SQL dialects, COM, .Net, and scripting languages\n\nMore from Dark Period: Less Slackware\n\n\n8. Gave Linux a try with Quantian Live CD in 2006 (Thanks, Dirk!)\n   https://dirk.eddelbuettel.com/quantian.html \n   https://dirk.eddelbuettel.com/quantian-tmp.pdf (PDF description)\n   https://dirk.eddelbuettel.com/quantian/quantian_0.7.9.2.quantian.packages.txt\n   \n * Used Live CDs to try Debian packages, repair PCs, and do math stuff\n  - Liked Gnumeric, Python, R, and educational software\n  - Wiped my Vista laptop in April, 2008 to install Ubuntu full-time\n  - Music, checking, and photo editing kept me from switching other PCs\n\n9. Tried Ubuntu \"Feisty\" using WUBI on Windows XP on Racing Cow\n * Trouble-free install, mainly because I was on an Ethernet cable\n   - Tried out Linux software in a risk-free environment to find what I liked\n   - GNOME 2 was close enough to Windows and Mac, so no problems with UI\n   - Command line was similar to Ultrix and even to DOS, so not so bad.\n\n * WUBI let me try Ubuntu without having to dual boot or use Live CDs\n   - Easy to install and remove, like a Windows application\n   - No messy virtualization setup\n   - Linux could see and use files on my Windows partition seamlessly\n\n * Ubuntu \"Hardy\" on \"Titanic\" (retired Dell Latitude D820 laptop)\n   - Install was easy, except for wireless networking\n   - Had to use NDISWRAPPER at first, but everything worked.\n\n * Switched my main home desktop (Racing Cow) in April, 2011\n  - Just in time for Unity, which would not run on my gear.\n  - Gnome 2 ran well on my computers, and they choked on Unity and Gnome 3.\n  - Taste and older machines led me to go distro hopping.\n  - Dan Lynch of Linux Outlaws pointed me to CrunchBang.  Try it.\n      https://crunchbang.org\n\n\n9. Other distros I've tried:\n\n * Gentoo (June 2011):  https://www.gentoo.org \n \n   Note: It is not as super-hard as you've been told.\n   \n   Installed it in three 4-hour sessions after reading docs on train\n    - Compiled kernel on first shot\n    - Added modules for devices I liked, and that recompile worked\n    - Got X working enough to use a browser and a window manager\n    - Gave up only because I had not decided on my workflows\n    - Was afraid to mix GTK and QT or KDE packages at that stage\n    - Unsure about reversing wrong choices \n    - Unfamiliar toolkits scared me, although I had no real problems\n  \n   Conclusion: My problem with Gentoo?  Between keyboard and chair. \n\n\n * Slackware (several times):  https://www.slackware.org\n   \n   Always installs on first try for me, with huge kernel\n    - Knowing what to do after initial install was the problem here, too\n    - To remove fear, I updated my 13.37 with all patches by hand\n    - Manual updates after install took 2 hours, including learning pkgtool\n    - Using generic or custom kernels is only hard when I'm stupid\n      * Be sure the drivers to operate your boot disk are compiled in\n   \n   Conclusion: After hating older versions, it's KDE 4 for the win!\n   \n     \n * SlackerMedia book:  https://slackermedia.info\n   \n   Helpful tips on designing workstation around workflows\n    - Uses SlackBuilds and SlackBuild queues for repeatable configuration\n    - Gave me idea for groups working on math software-in-progress\n    - Slackware package format is simple, easy to grasp (for binaries)\n    - SlackBuilds: close to a universal format for sharing program source\n   \n   Why Slackware?\n    - There are SlackBuild scripts for Sage and other packages I like\n    - Slackware comes with support for TeX for math writing\n    - SlackerMedia has queues for audio, video, web editing, publishing\n   \n   Conclusion: SlackerMath is born.  Still needs to be fleshed out.\n    - Slackware distribution-from-scratch based on SlackBuilds\n    - Set it up as you wish using your own custom queues\n    - Suggested packages would include Sage, R, Octave, GSL, QuantLib,\n        Grass GIS, kile, gretl, Tux Racer, euler, gnucap, and others\n    - Languages: Python with NumPy/SciPy/matplotlib and bindings to \n        other languages/libraries, Scheme, Perl, Lua, C and Fortran\n        \n * Also tried the following, but didn't stay with them\n   - Slax (www.slax.org)\n   - \n11. Right now: \n  * Five of our six former Windows computers have switched to Linux.\n    - \"Surfing Cow\" decommissioned with CrunchBang as its final O/S.\n    - \"Racing Cow\" still going strong with CrunchBang\n    - Sony FE laptop \"White Cloud\" running Ubuntu 13.04\n    - Derringer is my audio editing machine, because it's under 3 lbs.\n    - Laptop \"Titanic\" died after a baptism in red wine\n      Back to life with new keyboard, disk, and name -- \"Lazarus\"\n      \n  * Number six (\"Dawn Pixie\") about to go to a Linux \"granny\" distro\n    - Linux Mint or PCLinuxOS (KDE version)\n    - Need a \"granny\" distros for generic use by all comers\n\n

      \nFirst of all, a correction. In the podcast, I mistakenly refer to one of the\ncoauthors of the language as Kevin Weinberger. My humblest apologies to Mr.\nWeinberger, whose actual first name is Peter. I also neglected to mention one\nof AWK's most interesting features: its automatic field splitting. I hope to\nsubmit a followup podcast soon in order to rectify these two glaring mistakes.\n

      \n

      \nAWK is a loosely typed interpreted programming language. Many useful functions\nin a UNIX programming environment, such as reading files, looping over input,\nmatching regular expressions, and splitting strings into fields have been\nabstracted and are presented to the programmer as native parts of the language.\nThis makes AWK ideal for text processing.\n

      \n

      \nThe basic structure of an AWK program is a list of rules. Each rule is made up\nof an optional pattern and an optional action. If the pattern is matched, the\ncorresponding action is run. When AWK starts up, it loads the supplied program\ntext, runs any rules with the special BEGIN pattern, then in turn, opens each\nfile supplied on the command line (or stdin if no files or a - are specified).\nEach file is split into records based on the value in the RS (record separator)\nvariable. AWK then loops through each record, splits it into fields based on\nthe value in the FS (field separator) variable, and loops through each rule in\nthe program. An empty pattern matches all records, so actions with no pattern\nrun for every record. An empty action causes the current record to be printed.\n

      \n

      \nThe operator most unique to AWK is the $ (field access) operator. When followed\nby an integer literal or variable holding an integer value, it returns the\ncorresponding field in the current record (counting from 1 up to NF, the number\nof fields special variable). $0 returns the entire record. If the supplied\ninteger is greater than NF, it is treated as an uninitialized variable, which,\nin AWK, is treated dually as either the empty string, or the number 0,\ndepending on the context in which it is referenced.\n

      \n

      \nThe most common type of pattern used in AWK (excepting, perhaps, the empty\npattern) is a regular expression literal. It consists of a regular expression\nenclosed in forward slashes. This syntax is inherited from ed, the standard\ntext editor, and has been passed down all the way to javascript. In AWK, a\nregular expression literal, alone as a pattern, is shorthand for $0 ~ /regex/,\nwhere ~ is the regular expression match operator (the string $0, current\nrecord, matches the supplied regular expression).\n

      \nHPR Episode: Using and Converting Between Units of Distance\n\nIntro: Last time, we talked in general terms about units, numbers and\nhow they might be useful in practice.  In this episode, we address some\nspecific measurement units that apply to distance and area, and how we\nmight convert from one system to another to better understand both.\n\nEntire point of this episode is this: Carry units in calculations on \n  distances and areas, and you'll have more success in using them in \n  your life.  \n\n\n\nSegment 1:  Review of Distance and Area conversions in the English system\n\n1. Links from last time\n\n   Table of Units: \n      https://www.csgnetwork.com/converttable.html\n\n   To see why the story is tremendously more complicated than my account\n      https://en.wikipedia.com/wiki/Mile\n\n   Fun article on the mile.\n      https://www.sizes.com/units/mile.htm\n   \n   High school student theme on the furlong.\n      https://www.writework.com/essay/history-furlong by silverAlex2000\n\n   Brief dictionary article on the mile, referenced by Dr. Math \n      https://www.unc.edu/~rowlett/units/dictM.html#mile \n      Referred by https://mathforum.org/library/drmath/view/61126.html\n\n   Resource: StackExchange Physics and Maths sections (\"mile\" question)\n      https://physics.stackexchange.com/questions/57785/difference-between-nautical-and-terrestrial-miles\n\n\n2. Converting between units\n   a. Units of distance usually defined as multiples of each other\n      - 1 mile = 5,280 feet            - 1 hand = 4 inches\n      - 1 foot = 12 inches             - 1 yard = 36 inches\n      \n      Skipping ahead to look at the metric system, we now have:\n      - 1 inch = 2.54 centimeters (exact). Regularized in recent years.\n\n   b. This works because there's consensus on Zero distance, so we don't\n         have to adjust for differing origins, as we do with the \n         non-absolute temperature scales like Fahrenheit and Celsius. \n      \n      - We'll get to temperature, non-absolute scales in a later show.\n\n   c. For absolute scales, we can convert from one unit to another using\n         a \"conversion factor\".  That is, we can convert a measurement \n         expressed in one unit to its equivalent in another unit by \n         multiplying or dividing by some number to stretch or compress \n         the original unit to match the target unit.\n\t \n      - Example: I know that 1 foot is 12 inches, so how many inches are\n          there in 10 feet?  How feet are there in 660 inches?\n      \n      - It is clear that a factor of 12 ought to be involved, but how do\n          I know when to multiply or divide by 12 in the conversion?\n      \n      - Wait!  I'm serious.  When you see this problem for the first \n          time, you have to think this through to get it right.  \n        * Without a system in place, you always have to think about it.\n      \n      - Answers in naive setup:\n          (i) 10 feet = (12 * 10) inches = 120 inches\n         (ii) 660 inches = (660 / 12) feet = 55 feet\n\n3. Having a system.  Or units conversion as \"multiplying by One\"\n   \n   a. In each of the solutions I wrote down above, I start with an \n         equation that looks like this: X inches = Y feet.\n\n   b. Inches are not feet, and this way of writing down the calculation \n        does NOT help you figure you how the conversions should work, or\n        whether you should multiply or divide to get the right answers.\n\n   c. Here's a system for creating conversion factors that tell you what\n        to do at each step in the units conversion process.  It is based\n        on the very obvious fact that when I multiply any number by '1',\n        its value remains unchanged.\n\t\n      - Start with one of the identities we wrote down at the beginning.\n\t    In this case, let's use:  12 inches = 1 foot\n\t  \n      - If I divide equals by equals, the results are equal.\n\t    So I can write:\n\t  \n\t                                   12 inches      1 foot\n\t  12 inches = 1 foot implies that  ---------  =  --------- = 1\n\t\t                                 1 foot      12 inches\n      \n      -\tGet the first term by dividing my original identity by (1 foot).\n      - Get the second term by dividing my original identity by (12 in).\n\n\n   d. To make a conversion from feet to inches, I use:\n   \n                           12 in    10 ft \n      10 ft * 1 = 10 ft * ------- = ------ * 12 in = 10 * 12 in = 120 in\n                           1 ft      1 ft\n      \n      - Note: In the fraction (10 ft) / (1 ft), the units \"cancel out\", \n                which leaves a unitless number.\n\t      \n      - Suppose we start with the other form for the conversion factor:\n   \n                               1 ft    10 square feet \n      10 feet * 1 = 10 feet * ------ = -------------- = ???\n                              12 in       12 inches\n      \n      - See?  When I use the form where the units don't cancel each \n          other, I get a resulting equation that is still correct.  It \n          just doesn't make much sense to me as a reader.\n      \n      - This is what you get when you \"divide by 12\" to convert feet to \n          inches, but the difference is that you KNOW something's wrong.  \n      \n      - You do not have to even look at the numbers to know that this \n         could not possibly be the right number of inches in 10 feet.\n\n\nBrilliant Insight #2: When you use unit conversion factors, you help \n  your cause by carrying along both sets of units in the form of a \n  fraction as you go through your calculation.  \n  \n  - If the units on the right-hand side of your final equation don't \n    match the units you want (after everything else cancels out), your \n    numerical answer is almost certainly WRONG.\n  \n  - The implication here?  To convert units of distance, you need to \n       multiply or divide by a \n       \n       conversion factor = (X New_Units) / (Y Old_Units).  \n       \n    When you do this, write the conversion factor in its full fractional\n       form, and carry out all of the multiplications and cancellations.\n  \n  - If you do the conversion this way, and the units match, you only \n       have to check your arithmetic to be sure you've got it right.\n\n  - If the units you want do not match those on the right side of the \n       equal sign, you are solving the wrong problem.  The equation may \n       be correct, but it is not expressed in the units you wanted.\n\n\n 6. Let's use the system to solve the second example:\n  \n                               1 ft       660 in * 1 ft \n      660 in * 1 =  660 in *  -------  = --------------- = 55 feet\n                               12 in        12 in\n \n      Why?  The \"inches\" units cancel out because they appear in both \n        numerator and denominator (top/bottom, upstairs/downstairs) of\n\t    the fraction in the next to last term, leaving only \"feet\".\n\n  Why people hate units and conversion problems:\n  https://www.regentsprep.org/regents/math/algebra/am2/leseng.htm\n\n  Comment: The \"algebraic\" approach suggested here is ugly, ad hoc in\n    nature, and unnecessarily complicated.  Forget about setting up\n    equations and going through formal operations to solve them.\n    \n    Choose your conversion factors so that the units work out properly\n    as a straight multiplication problem with cancellation of all the\n    units you don't want.  You may have to \"divide\" numbers, but you\n    can use your calculator for working through the numbers.\n    \n  Cranky Summary: You should not have to solve equations to convert\n    between units. Phooey on anyone who says otherwise. :-)\n \n\nSegment 2: Conversions using compound conversion factors.\n\n1. Suppose I want to find the number of inches in a furlong, or the \n   number of acres (or hectares) in a square mile?\n   \n   - My almanac doesn't carry these conversion factors, so I start with \n       what I do have and work my way through it.\n       \n                                       4 rods    16.5 ft    12 in\n   1 furlong = 10 chains = 10 chains * ------- * ------- * -------\n                                       1 chain    1 rod      1 ft\n\t\n\t     = 10 * 4 * 16.5 * 12 inches = ... = 7920 inches \n\n\n2. For acres in a square mile (1 mi^2), we have a bit more to do.\n\n     Abbreviations used: miles = mi, furlong = fur, chain = ch\n     \n     Area means that we are dealing in two dimensions, so we have to \n        convert the lengths in each dimension.  An acre is already a \n        measure of area, so we're good.\n\t\n                       1 acre    10 ch    8 fur   10 ch   8 fur\n   1 sq mi = 1 mi^2 * -------- * ------ * ----- * ----- * -----\n                       10 ch^2   1 fur    1 mi    1 fur   1 mi\n\t\t      \n\t   = (1 mi * 1 mi) * 1 acre * 10 ch * 10 ch   8 fur * 8 fur\n\t                              ------------- * -------------\n                                       10 ch * ch     1 mi * 1 mi\n     \n   Units cancel, leaving this:\n   \n   1 sq mi = 1 acre * (100/10) * (8 * 8) = 10 * 64 acres = 640 acres\n  \n   \n\nSegment 3: Hey!  Ready to try metric?\n\n1. Metric system never caught on in the US, although most of English-\n     speaking world has adopted it.  Units conversion is easy in the \n     metric system, because everything is in powers of 10.\n   \n   - But you still need to carry along units in calculations!\n   \n2. Area and distance units in the metric system\n\n   - Basics of distance: Centimeter is easy for us to see, and now the \n       factor to convert centimeters to inches is exact.\n       \n       1 inch = 2.54 centimeters (cm) exactly\n       \n                                    1 inch\n       1 meter = 100 cm = 100 cm * --------- = 39.37 in (approximate)\n                                    2.54 cm \n\n       1 kilometer = 1,000 meters\n       \n\n   - Basics of area:\n \n       1 are = 100 sq meters  (area of a square that's 10m on each side)\n       \n                                          100 sq m\n       1 hectare = 100 ares = 100 ares * ---------- = 10,000 sq meters\n                                           1 are\n\n3. For short distances, we should do our conversions fairly precisely.\n\n   - There's usually a higher relative error from rounding off too soon.\n   - If you measure wood for a small project, you want to be \"close\".\n\n                        2.54 cm\n   So 1 foot = 12 in * --------- = 30.48 cm exactly.  Cut carefully!\n                        1 in\n\t\t\t    \n4. For larger distances, like distances covered in track and field, or\n     the length of a football pitch (to a spectator), approximations can \n     give you a nice intuition for comparing units you know and a new\n     set of units that you don't know as well.\n     \n   - 1 meter is around 39.37 inches.  Suppose I call it about 1.10 yards\n        as a kind of approximate benchmark (39.60 in), so each meter in \n        my reckoning is about a quarter of an inch too long?  \n   \n   - If I'm planning a space mission, I could be in trouble. \n       But how bad would this be for getting an intuitive feel of the \n       distances covered by the athletes in the Olympic Games?\n\n   - Error at  100 meters is about 0.23 in (0.6 cm) * 100 = 60 cm over\n           at  200 meters, it's 1.1 m over.\n           at 1 kilometer, it's 5.6 m over.\n\t   \n     Unless you're a long-range sharpshooter, 5.6m off in 1 km seems OK.\n\n\n5. Bonus: The news talked about a wildfire that burned 100,000 hectares.\n      What kind of area are we talking about?\n\n   - Let's use our approxmation of 1 meter is about 1.1 yards.\n   \n   - Acres are defined in terms of \"square chains\", so let's look at \n        meters vs chains to see what we get.\n\t\n\t                                               1 m\n     1 chain = 4 linear rods = 22 yds = 22 yds * -------- = about 20m\n                                                  1.1 yd\n\n                                                 20m     20m\n     1 acre = 10 square chains = 10 ch * 1 ch * ----- * ------\n                                                1 ch     1 ch\n\t\t\t\t\t\t       \n\t    = 10 * 1 * 20m * 20m = 4,000 square meters, or 0.4 hectares\n\n   - Wow!  An acre's about 0.4 hectares, or 1 hectare's about 2.5 acres.\n\n\n   So what's the answer?\n                                               2.5 acres   \n      a) 100,000 hectares = 100,000 hectares * --------- = 250,000 acres\n                                               1 hectare \n\n\n                                            1 sq. mi    250,000\n      b) 100,000 hectares = 250,000 acres * --------- = ------- sq. mi\n                                            640 acres     640\n\t\t\t\t\t    \n\t                  = 391 sq. miles (about 400 sq miles)\n\n   Note: This suggests a shortcut conversion (hectares to square miles).\n\n                                 640 acres   1 hectare\n    1 square mile = 1 sq. mile * --------- * --------- = 256 hectares\n                                 1 sq. mi.   2.5 acres\n\n\n6. Final check: Error analysis on this approximate conversion from \n      hectares to acres or square miles.\n\n   - Using Google or 'units' in the shell, we have:\n   \n     1 sq mi = 259 hectares to 6 significant digits, versus 256 (1%)\n\n     Note: If we used 250 hectares per square mile, the relative error \n       is 3.5%.  That's less than the error in the news report.\n\n     1 hectare = 2.47105 acres, versus 2.5 (1% error)\n\n   Units shell command: Dann Washko did a really nice job on 'units' for HPR.\n    * Linux in the Shell #26: https://www.linuxintheshell.org/\n    * HPR Episode #1213: https://hackerpublicradio.org/eps.php?id=1213\n\n\nFinal word: Unless you are buying, selling or cultivating land, use the \n  cruder approximations here to understand the relationships between \n  acres, hectares and square miles.  It will make you seem smarter.\n  \n  - If someone calls you out and says it's wrong, blame \"that guy on HPR.\"\n\n\nNext Topic?  Volumes and recipes, other than medicines (separate topic)\n  - Volumes are the bottom line in cooking, unless they aren't.\n  - Hint: You should weigh some items, like some kinds of flour.\n

      \nOne of the key techniques in using a spreadsheet is to master the art of fills, which lets you fill a column or a row with data without having to type in every cell individually. And this technique requires that there be a predictable pattern to the contents of each cell as you fill them. But you can do a lot with this technique, and we will want to use this when we do our first model, which will be a simple savings model.\n

      \n

      \nBut first we need to build the tools in our tool kit, and fills are a big one. To begin with, you can fill either rows or columns, though columns are more frequently filled using this technique. Still, it is good to know you can do either. The simplest fill begins with a cell that has some kind of contents. For example, lets say that cell B1 contains the word \"Rain\". If you click on the cell, you will see it highlighted with a thick black border\n

      \nThis episode is a just-for-fun show in which I make a few observations in defense of just playing around. We need to \nstop worrying about work and to-do lists every once in a while in order to just get up off our chairs and do something\nthat is fun. It doesn't have to have a structure at first, but it should involve a challenge or exposure to at least\none new thing, or place, or person, or idea.\n\nI think it is the best way to learn, because the knowledge and acquisition of skills sneak up on you while you are\nhaving fun. It may be the only way to make learning really stick, and to stick with the learning process.\n

      \nIn this episode I discuss the problem of increasingly expensive college textbooks, and share with you the solution I devised to combat the problem in my counterpoint class at the University of Louisiana at Lafayette.\n

      \n

      \nPart of the solution is to adopt a public-domain textbook that's more than 100 years old, and to give the text a 21st-century makeover that I believe will make it even better-suited for the digital age than any other comparable book in the market at any price.\n

      \n

      \nhttps://jonathankulp.org/gratis.html: \nThe counterpoint page on my website, with source files and information about my creative-commons counterpoint workbook, \"Gratis ad Parnassum,\" as well as links to the 1910 counterpoint textbook by\nPercy Goetschius: https://en.wikipedia.org/wiki/Percy_Goetschius entitled \"Exercises in Elementary Counterpoint.\"\n

      \nThis is a show concept I came up with half a decade ago, as the show itself explains. The journal article may be found as PubMed ID#19323757 ( https://www.ncbi.nlm.nih.gov/pubmed/19323757 ) if you want to follow along.\n

      \nHopefully the updated time references below for the show-note comments are now correct for this version of it. They should be close, anyway. \n

      \n

      \nAlso, I'm oddly pleased at how inferior the \"old\" part of today's episode sounds: it means I've actually gotten a lot better at recording and editing.\n(It's quite listenable still, I think, it just doesn't sound as good as the newer stuff.)\n

      \nThe next topic is extremely important because it addresses where most beginning users of spreadsheets get into trouble. First, understand that building models and doing \"What-If\" analysis is fundamental to the success and widespread adoption of spreadsheets all over the world. A model can be thought of as a mathematical representation of a process of some kind. It could be financial, such as projecting my sales over the next year, or perhaps working out when my car loan will be paid off. Or it could be scientific, such as projecting out the reaction times and quantities in a chemical reaction. The only real requirement is that whatever you are modeling has to be something that can be represented using mathematical formulas of some kind.\n

      \n

      \n\"What-If\" analysis takes this model and lets you experiment to see how how changes in different variables affect the results in your model. If I am figuring out when my car loan will be paid off, I might ask how paying an extra $20 per month against the principle would affect my results (presumably, it should lead to getting it paid off sooner if I set the model up correctly.) Or in the case of the chemical process, how would different temperatures or pressures affect the reaction times and quantities? By experimenting with different values in my model I can do this comparison easily. But only if I built the model properly in the first place.\n

      I listen to a lot of podcasts. I started listening to them back in around 2005 after buying my first portable player.

      \n

      I now listen to podcasts to the exclusion of just about everything else and have several players which I rotate between. I gave up watching TV over two years ago. I have written my own podcatcher software based upon Bashpodder, with a PostgreSQL database to manage everything, which holds feed, episode, playlist and player details.

      \n

      My interests range from Astronomy to Virology with a bias towards IT-related subjects. I currently subscribe to 85 feeds, which I present to you here in two batches. I have attached my own category to each feed, so I can load all the Science episodes on one player, and Documentary episodes on another, and so forth. I have added the category to the list as well and have sorted the list by category and the title.

      \n

      Note: The list below is generated by a script which performs a query on my database. I have relied on parsing the feeds themselves for the websites, using the link value. In a few cases the value is unfortunately incorrect or missing because the feed is mis-configured.

      \n

      I have included an OPML version of the list in case you want to load it or part of it into your podcatcher. Find it at hpr1516.opml

        • Description: This Week in Microbiology (TWiM). A podcast about unseen life on Earth hosted by Vincent Racaniello and friends. Following in the path of his successful shows 'This Week in Virology' (TWiV) and 'This Week in Parasitism' (TWiP), Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background. As a science Professor at Columbia University, Racaniello has spent his academic career directing a research laboratory focused on viruses. His enthusiasm for teaching inspired him to reach beyond the classroom using new media. TWiM is for everyone who wants to learn about the science of microbiology in a casual way. While there are no exams or pop quizzes, TWiM does encourage interaction with the audience via comments on specific episodes, email and Skype. Listeners can also use www.MicrobeWorld.org to suggest topics for the show by submitting articles, papers, video and images to the site and tagging them with \"TWiM\". Each week Racaniello will view the tagged content and select items for discussion. For questions and/or feedback please email ccondayan@asmusa.org.

      \nIn this short article I want to talk about prime numbers. In particular:\nabout the fact that there exist an infinite number of prime numbers. This\nhas been proven more than 2000 years ago, but I noticed that a lot of\nmy friends that don't have a mathematical background, aren't aware of\nthis fact.\n

      \n

      \nYet it is rather easy to prove. So that is what I'll be doing in this\narticle. If you are afraid of math, don't worry, it won't take more than\n10 minutes.\n

        • Description: Rationally Speaking is the bi-weekly podcast of New York City Skeptics. Join hosts Massimo Pigliucci and Julia Galef as they explore the borderlands between reason and nonsense, likely from unlikely, and science from pseudoscience. Any topic is fair game as long as we can bring reason to bear upon it, with both a skeptical eye and a good dose of humor! We agree with the Marquis de Condorcet, who said that in an open society we ought to devote ourselves to \"the tracking down of prejudices in the hiding places where priests, the schools, the government, and all long-established institutions had gathered and protected them.\" Rationally Speaking is produced by Benny Pollak and is recorded in the heart of New York City's Greenwich Village.

      In the previous tutorial we discussed the fundamental ideas of building models and doing “What-If?” analysis. Now we need to take these ideas and put them into practice so you can see how this works. To do this I will create a simple model of savings over time. Now, I do want to be clear that this is a very over-simplified model and should not be taken as a good predictor of actual results. The idea is to illustrate the techniques involved in building a model and doing “What-If?” analysis.

      So. what are the variables, parameters, assumptions, etc. that we need? I have identified these in my model:

      • An initial amount of money already saved. This is the starting amount you have.
      • An amount of money you add to your savings each year.
      • The rate of return on your savings

      \nI have spent many, many hours in a vehicle driving around. While travelling,\nI've found a GPS to be one indispensable tool. These are some of the\nGPS-related tips that I have discovered:\n

      \n\n
        \n
      • Having a \"navigator\" - someone else to help operate the GPS - can be very\n helpful in stressful driving situations. If you have someone that can help,\n let them handle GPS programming.\n
        • \n
      • Know how to operate your GPS. Planning routes are just the beginning; know how\n to get your GPS to find food and lodging nearby, and how to change a route to\n avoid trouble (road closures, traffic jams, detours).\n
        • \n
      • Update your maps! Old map data can drive you into construction zones or route\n you into congested areas that new map data would have let you avoid.\n
        • \n
      • Be aware of tolls! The Northeast loves road tolls, and they can quickly add\n up. My GPS has the option to route around toll roads; so you can use that, or\n make sure you are prepared for that expense.\n
        • \n
      • You can also use your GPS as a normal map, except it's a map automatically\n centered on your exact position. In certain situations, this can be more\n useful than having your GPS provide you with directions.\n
        • \n
      • My GPS tells me the local speed limit, in addition to how fast I'm going. This\n is an excellent way to avoid getting a ticket.\n
        • \n
      • Mount your GPS somewhere. Looking down into your lap is a good way to find\n yourself in a gutter.\n
        • \n
      • GPS are not 100% accurate! Don't believe their lies! If the directions they\n are giving you sound bogus, use your better judgement.\n
        • \n
      • BONUS: Cameras! If you want to take pictures while on the road, try leaving\n your camera set to the \"Landscape\" macro if you have that option. It will\n prevent focus issues when taking quick shots. Also, keep your camera\n easily accessible to avoid extra distraction. If you have a navigator, they\n might be the best photographers.\n

      If you run a blog or a podcast, promoting your material can take as much time (or more) than content creation itself. Just like a small business marketing and promoting your efforts take time, effort and energy that can take you away from what you'd rather be doing: making great stuff.

      \n

      This podcast discusses the germ of an idea, and its fledgling implementation, for creating an open-source tool for managing the distribution of posts to social media and doing it in as non-spammy a way as possible.

      \n

      The premise is simple: take information from a number of disparate sources, and promote it to a number of disparate destinations. The challenge is doing it without violating the social norms of the destination networks, and without crossing the line between promotion and spaminess.

      This episode covers various editing techniques you might use, including multiple sheets, and adding, removing and hiding rows and columns. We also discuss how to navigate around a multiple sheet spreadsheet.

      \n

      LibreOffice Calc, like all spreadsheets, contains a large number of cells in various rows, columns, and sheets, and navigating that can get a little tricky. As we saw previously, each cell has an address, which is marked by the column (letters) and the row (numbers), always in that order. But in fact the address can be larger because we never discussed sheets.

      \n

      By default, when you create a new Calc spreadsheet you will have three sheets in it, which you see as tabs along the bottom of the screen. They will be called Sheet 1, Sheet 2, and Sheet 3 at this point. But these defaults can be changed by going to Tools–>Options–>LibreOffice Calc–>Defaults. On this screen you can decide how many sheets you want to have on a new document. While the default as it comes is three (similar to Microsoft Excel) you can change it. On my copy of Calc I changed it to 1, because most of the time I never need more than one sheet for my work. I can also change the default naming of new sheets here. Instead of each sheet being “Sheet 1″, Sheet 2″, etc. I could make it something else, like “Tab 1″, “Tab 2″. and so on. I never bother with this though, because I will always name my sheets for what they are doing in a given spreadsheet (e.g. look at what I did when I created the simple model for “What-If” analysis.) And if I need to add a sheet, I can just go to Insert–>Sheet to bring up a window to specify where the sheet should go, what it should be named, or even insert a sheet from a file . A CSV file would be a very good choice here, such as if you wanted to bring in data from a database or another spreadsheet for use in the current spreadsheet.

      IT Solutions Expo 2014

      \n

      In April 2014 I visited the \"IT Solutions Expo\" at the conference centre known as \"The Swedish Fair\" in Gothenburg. The tagline of the IT Solutions Expo was \"The fair that shows you how to make money on tomorrow's IT solutions\".

      \n

      So a lot of corporate propaganda and sales people. To be totally honest, I hesitated going there. But I am glad I did. There where some really interesting talks concerning privacy and technology that I would not have liked to miss.

      \n

      Agnes Andersson Hammarstrand, IT Lawyer

      \n

      The real highlight of the fair was the talk by Agnes Andersson Hammarstrand, a lawyer specialised in information technology. She covered the new laws that will come to pass in the European Union regarding how we are allowed to handle personal data.

      \n

      I was very happy that she was willing to give a short interview for Hacker Public Radio.

      \n

      It is interesting to see that it is not only consumers who are starting to think that information about us should be kept safe, it is also slowly becoming the law. If your work in or with companies in the European Union, this is definitely a heads-up, something to take notice of. In a couple of years time you must be ready to follow the new legislation.

      \n

      In her talk Agnes also mentioned that companies should have someone who is responsible for privacy issues. Perhaps this is an opportunity for the HPR listeners? Most of you probably feel that this is an important topic already, so why not make it a part of your job description?

      \nAs usual, during this episode of the AudioBookClub the hosts have each reviewed a beverage of their choice.\nMorgellon drank a Bourbon and soda, but not during the show because he was driving. He recommends both Woodford Reserve https://www.woodfordreserve.com/ and Evan Williams Bourbons https://www.evanwilliams.com/\nx1101 drank Wild Turkey 101 proof Bourbon https://wildturkeybourbon.com/\npokey drank a cup of Oolong tea. It was probably a little stale, but pokey is a knuckle dragger, so he didn't notice at all. https://www.foojoyteas.com/teabag.php . This was the first time that pokey has reviewed an NA beverage for the AudioBookClub, so we apologize if the show has suffered because of it.\nThaj won the Non-Alcoholic division hands down with a glass of fresh squeezed lemonade.\nColin couldn't make it to this recording because of time zone differences, but he did write in. I'll add his note to the episode comments. Please add your own comment as well. His beverage however was an Innis and Gunn Original https://www.innisandgunn.com/the-range/core-range/original/ to which he gives his thumb up.\n

      Writing screenplays for TV or movies is a very precise thing. The industry expects a standardised style and format. ThistleWeb explores a couple of dedicated screenplay writing solutions. Both are dedicated applications that do one job and do it very well. The first is Trelby. It's a GPL cross platform application. It has lots of additional features such as auto completion of character names, summaries and stats.

      \n

      The second application is a cloud service called Raw Scripts. It's a Chrome extension although I think that's just a link to the site. You log in with a Google or Yahoo account. It's like a dedicated Google Docs web app. It does most of the things Trelby does. It also exports to Google if you want. You can share and collaborate with Raw Scripts. It's hosted on their server, although it's AGPL going forward, so it shouldn't be long before you can host it on your own server.

      \n

      I've just started to explore screenplay writing as a writing skillset. Both of these applications make the styling and formating incredibly easy, allowing me to concentrate on the actual story.

      We have looked at e-mail encryption on both Thunderbird and G-Mail, and that is good, but in 2014 a lot of people use mobile phones and tablets for their e-mail. So it makes sense to look at how we can do this. The solution I am going explore here involves two components, the K-9 Android mail client, and APG, the Android Privacy Guard. I am going to stick to what I know, so if you are looking for help with iPhone or iPad, the best I can do is suggest that you try a Google search. On Android, while many people use Gmail, K-9 is a very popular client for people looking for a more traditional POP3 or IMAP client to handle their e-mail needs. So this should be a good solution for many people. As regards APG, I am not aware that anyone has done an audit of this program. It seems to be the most widely recommended, and is probably OK, but I am making no larger claims for it. - For more go to https://www.zwilnik.com/?page_id=602

        \n Debian has a fully accessible installer. I have installed Debian 7.4 from the net install CD ISO image. The installer is text-based and presents no problem for even the totally blind.
        \n See the Debian Accessibility page linked to above.\n
        • \n
      • Ubuntu Accessibility: https://help.ubuntu.com/community/Accessibility \n The Ubuntu 'Ubiquity' graphical installer is totally accessible. Installing from a live CD or DVD image is simple. See the page linked above. \n
        • \n
      • Vinux (an Ubuntu variant which is accessible out-of-the-box): https://vinuxproject.org/ \n This is an Ubuntu variant which comes up talking from the first. Not only is the installer accessible, but considerable attention has been paid to including only applications which are accessible on the CD and DVD images. Applications which are either inaccessible or which simply have little or no relevance to the visually impaired are excluded.\n
        • \n
      • Talking Arch: https://talkingarch.tk/\n Chris Brannan created an accessible ISO image of Arch Linux.
        \n This uses the speakup console-mode screen-reader to provide a way of installing Arch Linux for the visually impaired. Console-mode only, but providing a great starting-point. I have tried various desktops on top of this installation, including mate, LXDE and others.
        \n Talking Arch is now maintained by a couple of names which will be familiar to the Linux VI community; Kyle and Kelly. Erm...embarassingly I can't find their last names right now.\n

      Blather Speech Recognition for Linux: Jon has a conversation with his computer

      \n

      In this episode I have a blather conversation with my computer. This is a sort of appendix to an episode I released earlier (hpr 1284 https://hackerpublicradio.org/eps.php?id=1284) which was a conversation with Jezra, the lead developer of the blather speech recognition program for Linux. The current episode will make much more sense if you listen to the previous one first.

      \n

      For the most part I use blather as an accessibility tool, to manipulate my desktop and generally to save myself hundreds of keystrokes a day. This is important because of my repetitive strain injuries. Blather allows me to do many “productivity” tasks using only my voice. I also like to have fun with it, though, and this “conversation” is an example of the sort of goofy stuff I like to do. When the computer hears me say certain predefined phrases, it runs commands. For example when I say “what’s for dinner,” it shuffles the contents of a plaintext file that has about 20 options for dinner, chooses the top option and pipes it through my default text-to-speech program, which is either espeak or festival, depending on what I set as the environment variable in my blather startup script. When it hears me ask for certain other information, such as “what day is it?” and “what’s today’s date?”, it runs the appropriate system command and pipes the output through the text-to-speech program. For information about blather, the various back-end things that make it work, examples of my blather scripts and configuration files, visit the links below.

      How to implement a many-to-many join in a relational database

      \n

      The purpose of this HPR show is to demonstrate the best, and really the only way to define a many-to-many relationship between two entities in a database.

      \n

      What triggered it?

      \n

      There has been some discussion between Ken and Dave on the community news podcasts, presumably relating to some work which is being done on the HPR web site. I sent Ken an email explaining how to implement a many-to-many relationship and got a predictable response; do a show :)

      \n

      So here it is.

      \n

      What do I mean by database entity?

      \n

      In analysing the structure of the data which is to be stored by a database, one of the most important things to do is to identify what entities are to be stored and manipulated.

      \n

      What constitutes an entity is often quite simple; some examples might be 'customer', 'billing address', 'shipping address', 'invoice', 'invoice item' etc.

      \n

      In fact it's also true to say that more often than not entities and tables have a one-to-one relationship. If the analysis of your data reveals that there is a 'customer' entity, then there will probably be a 'customer' table.

      \n

      One area where this might not be quite true is where the mechanism used to implement the whole software system demands a greater level of granularity. There are some e-commerce systems which are written with object-oriented technology and which demand that the data model matches the objects in the system. Typically this results in a data model that might look like it is over-normalised.

      \n

      But for the sake of this example, we will assume that one entity occupies one table.

      \n

      In fact if you find your analysis has any two tables that appear to have a one-to-one relationship, there is probably something wrong with your analysis because these two tables could be merged into one.

      \n

      Entity Relationships

      \n

      In a database system comprised of a number of tables, one table per entity, there will be complex relationships between the entities. This is the reason we talk about 'relational' databases. Or perhaps it is because all the columns in a table are supposed to be related to the unique identifier in that table, not sure, and neither was Mr. Codd.

      \n

      Types of relationship

      \n

      One-to-many or many-to-one, depending on which end of the telescope you are looking through. For example a customer might make one, or many purchases from your company e-commerce system. In which case there will be a one-to-many relationship between the 'customer' table and the 'invoice' table in the sales ledger.

      \n

      Note that if the customer has only ever made one purchase there will only be one row in the invoice table, but it COULD contain more. The more end is really one-or-more.

      \n

      Because one visit to the web site might result in the customer dropping more than one item into his shopping cart, there will also be an 'invoice lines' or 'invoice items' table.

      \n

      How these relationships are represented on diagrams

      \n

      Classically an entity relationship diagram consists of a series of rectangles, one for each table with the name of the entity written in the box. The entity rectangles are joined together by lines. These lines have what are usually called 'crows feet' at the 'many' end. A crows foot looks just like what it says, where the line joins the many end of the join, the line splits into three prongs before it hits the side of the many entity rectangle. Depending on what mechanism has been used to create this diagram, the crows foot can also look more like a fork than a crows foot, but there are still three prongs.

      \n

      In this text I will use a line consisting of dashes to join entities, and a backwards left or right arrow to represent the many end of a relationship.

      \n

      So, using the example above, the one-to-many relationship between customer and invoice looks like this:

      \n\ncustomer-----<invoice\n\n

      Here the less-than sign is used at the many end and should be thought of as a crows foot with the middle toe missing.

      \n

      How to join two tables in a many-to-many relationship

      \n

      You will not come across this relationship very often. It is far less common than a simple one-to-many or many-to-one.

      \n

      One example where this might be useful, and the example I use in this text, is a music database where two of the entities are:

      \nArtist\nGenre\n\n

      Clearly there will be multiple artists, and multiple genres. And it is not inconceivable that an artist might appear in more than one genre. And a given genre will clearly contain more than one artist.

      \n

      So this gives rise to a many-to-many relationship, which in pure analysis terms could be diagrammed like this:

      \nartist>-----<genre\n\n

      But this is NOT the way to define it in actual physical database tables.

      \n

      Observing the rules of normalisation, an artist should be identified by one property, the artist name, and a genre should be identified by one single property, the genre name.

      \n

      More often, and in our example below, each entity is given a unique identifier which is in addition to it's actual name.

      \n

      This is how changing a simple name in one table can result in the change being seen globally over the entire database system. For example in a customer table, the row:

      \nid  name\n--  ----\n1   Mickey Mouse\n\n

      Will cause 'Mickey Mouse' to be shown as the customer name wherever the identifier '1' is used to retrieve records or to join tables in a complex SQL query.

      \n

      Change 'Mickey Mouse' to 'Donald Duck' in this table, and 'Donald Duck' will appear everywhere 'Mickey Mouse' was seen before.

      \n

      Foreign Keys

      \n

      When two tables are to be joined to make a query, columns, or multiple columns are given indexes. A column which contains the key from another table is called a 'foreign key'.

      \n

      Going back to our customer and invoice example from above, the invoice table will contain the customer identifier from the customer table. And because a single customer can make more than one visit to our web site to buy stuff, the column containing the customer identifier in the invoice table is not given a unique index.

      \n

      If the customer with the identifier '12345' has made five different shopping excursions to our site, there will be five rows in the 'invoice' table containing the customer identifier '12345'.

      \n

      Armed with this information, how will we represent this:

      \nartist>-----<genre\n\n

      Clearly the artist table should contain a foreign key from the genre table, and the genre table should contain a foreign key from the artist table.

      \n

      The rules of normalisation say that all the attributes in a table (columns) should relate to the primary key of the table. Clearly putting a genre foreign key into the artist table, or an artist foreign key into the genre table busts this rule wide open. Don't do it

      \n

      The solution

      \n

      To solve this problem we introduce another table between the artist table and the genre table, which I always suffix with '_xref', short for cross-reference.

      \n

      Now our entity relationship diagram will look like this:

      \nartist-----<artist_genre_xref>-----genre\n\n

      What does the artistgenrexref table contain? Simple, it contains the bare minimum to define a unique row which joins an artist and a genre.

      \n

      If the artist identifier is called artistid and the genre identifier is called genreid, then the xref table contains two columns:

      \nartist_id\ngenre_id\n\n

      What kind of index do we need on this table to make a unique relationship between an artist and a genre? We need a unique compound index which uses both columns.

      \n

      This will ensure that one and only one row can appear in the table joining one artist to one genre. But because an artist can belong to more than one genre, both columns in the index mean this is possible.

      \n

      A worked example

      \n

      In the example code and data below, I have used SQLite3.

      \n

      SQLite is the world's most used Relational Database System (RDBMS).

      \n

      How can this claim be made?

      \n

      Well if you have a smart-phone in your pocket, it probably uses SQLite. If you have a satellite TV receiver, a Tivo or some other kind of home media device, it probably contains SQLite.

      \n

      And if you are really strange and have a fridge which will tell you what's inside, it probably uses SQLite. And there will be one row which says 'half an onion wrapped in foil which has been in here for six months'.

      \n

      Several times I have been brought Blackberry hand-sets and asked to retrieve important documents or texts from it when the user interface mechanism has failed. Something that often happens with that flavour of soft fruit.

      \n

      SQLite is easy to install on your Linux machine. In fact it is used by so many other packages that it may well be on there already. But you may have to install the interactive SQLite3 program.

      \n

      On Arch Linux:

      \n$ sudo pacman -S sqlite3\n

      On Debian or Ubuntu:

      \n

      $ sudo apt-get install sqlite3

      \n

      Below I have inserted the contents of all the files which I created to demo this many-to-many relationship strategy.

      \n

      Each file is topped and tailed by the string '--snip--'. In the SQLite3 interactive program, a double dash ('--') starts a line comment. Each file also contains the name of the file and a description of what it does.

      \n

      An exception is the .csv files I have used to load data into my little test database. These have the '--snip--' tops and tails in this text but they do not exist in the actual data, for obvious reasons. If you are snipping out the csv data to try this at home, don't include anything but the data lines in the csv data.

      \n

      To start an interactive SQLite 3 prompt and create your test database, do this at a Linux or Windows command prompt. Here the prompt is represented by a dollar sign:

      \n$ sqlite3 music.db\n\n

      You will get this prompt:

      \nsqlite>\n\n

      Because the first thing I alwys want to know about apiece of software I haven't used before is how to get out, to get out of the interactive SQLite3 session, type this, of course 'sqlite>' is the prompt:

      \nsqlite>.quit\n\n

      To run a file of commands you have defined in an external file, do this:

      \nsqlite>.read filename\n\n

      Where 'filename' is a file containing dot prefixed commands and/or SQL.

      \n

      The files from my working example:

      \n

      The following file contains commands to create tables and indexes in the database named on the command-line when you called sqlite3.

      \n--snip--\n--\n-- file name: ddl.sql\n--\n-- ddl = 'data definition language'\n--\n-- This SQL creates three tables, the artists table tbl_artist,\n-- the genre table tbl_genre, and the cross-reference\n-- ttable tbl_artist_genre_xref\n--\n-- The xref table is what provides the many-to-many relationship\n-- between artist and genre by virtue of it's\n-- compund index; idx_artist_genre_xref,\n-- which has two columns included in it\n--\n-- I use the tbl_ prefix for tables and the idx_ prefix for indexes.\n-- These might seem redundant but they are useful for preventing\n-- collisions between database component names and reserved words.\n--\n\n-- Create the artist table\ncreate table tbl_artist (\n    artist_id integer not null primary key,\n    artist_name text not null\n);\n\n-- Create the genre table\ncreate table tbl_genre (\n    genre_id integer not null primary key,\n    genre_name text not null\n);\n\n-- Create the artist_genre_xref table\n--\n-- I use number for both columns instead of integer because SQLite\n-- does something funky with auto-incrementing integer\n-- columns which have a 'not null' constraint, I think\ncreate table tbl_artist_genre_xref (\n    artist_id number not null,\n    genre_id number not null\n);\n\ncreate unique index idx_artist_genre_xref on tbl_artist_genre_xref (\n    artist_id,\n    genre_id\n);\n\n--snip--\n\n

      There follow three files which contain comma-separated values (.csv) records for loading into each table.

      \n

      The first is artist data:

      \n--snip--\n1,\"Horslips\"\n2,\"Runrig\"\n3,\"The Pogues\"\n4,\"Led Zeppelin\"\n5,\"Disturbed\"\n6,\"Martin Carthy\"\n7,\"Steeleye Span\"\n8,\"Schubert\"\n9,\"Mozart\"\n--snip--\n\n

      The first three artists fall into both the folk and rock genres. Led Zeppelin and Disturbed will be in rock only.

      \n

      Martin Carthy and Steeleye Span are folk only.

      \n

      Schubert and Mozart need no further explanation.

      \n

      The next is data to load into the genre table:

      \n--snip--\n1,\"Folk\"\n2,\"Rock\"\n3,\"Classical\"\n4,\"Scottish\"\n5,\"Irish\"\n--snip--\n\n

      The last data file is the data which will be loaded into the artistgenrexref table. It contains only numerical data:

      \n--snip--\n1,1\n2,1\n3,1\n1,2\n2,2\n3,2\n4,2\n5,2\n6,1\n7,1\n8,3\n9,3\n1,5\n3,5\n2,4\n--snip--\n\n

      What is this data doing? Well there are some artists there which will appear in both the 'folk and the 'rock' genres. Horslips are a seventies Irish folk-rock band. I still play their 'The Book of Invasions' album at least once a week. This is either because it is a seminal album or because I am a dinosaur who refuses to be dragged kicking and screaming into the 21st century. Runrig are a band from the Western Isles of Scotland who cross over the folk/rock boundary also. Check links at the end of this text.

      \n

      The next file loads the data from these .csv files into the three database tables.

      \n--snip--\n--\n-- file name: load.sql\n--\n-- Load some data into the tables from three CSV files\n--\n.separator \",\"\n.import artist.csv tbl_artist\n.import genre.csv tbl_genre\n.import xref.csv tbl_artist_genre_xref\n--snip--\n\n

      There now follow some SQL queries which retrieve data-sets which should be obvious from the file names:

      \n--snip--\n--\n-- file name: select-folk-only.sql\n--\n-- This is where the SQL gets a bit hairy, using a sub-query to exclude\n-- everything except the category we want from the record-set.\n--\n-- This is the kind of situation where a view\n-- might be useful to hide some of the SQL complexity from\n-- the user.\n--\nselect a.artist_id, a.artist_name, x.genre_id\nfrom tbl_artist as a, tbl_artist_genre_xref as x\nwhere a.artist_id = x.artist_id\nand x.genre_id = 1\nand a.artist_id not in (\n    select a.artist_id\n    from tbl_artist as a, tbl_artist_genre_xref as x\n    where a.artist_id = x.artist_id\n    and x.genre_id != 1\n);\n\n--snip--\n\n\n\n--snip--\n--\n-- file name: select-folk.sql\n--\n-- Straight-forward query to select artists that appear in the folk\n-- category.\n--\n-- This will return artists that appear in the folk category, which\n-- includes artists that appear either exclusively in folk or in BOTH\n-- folk and any other category also.\n--\n-- A little hard to get your head around.

It uses a sub-query to\n-- exclude everything except the category we want from the record-set.\n--\n-- This is the type of query where a view might be useful to hide some\n-- of the SQL complexity from the user\n--\nselect a.artist_id, a.artist_name, x.genre_id\nfrom tbl_artist as a, tbl_artist_genre_xref as x\nwhere a.artist_id = x.artist_id\nand x.genre_id =2\nand a.artist_id not in (\n    select a.artist_id\n    from tbl_artist as a, tbl_artist_genre_xref as x\n    where a.artist_id = x.artist_id\n    and x.genre_id != 2\n);\n--snip--\n\n\n\n--snip--\n--\n-- file name: select-rock.sql\n--\n-- select all artists which appear in the rock category\n--\nselect a.artist_id, a.artist_name\nfrom tbl_artist as a, tbl_artist_genre_xref as x\nwhere a.artist_id = x.artist_id\nand x.genre_id = 2;\n--snip--\n\n\n--snip--\n--\n-- file name: select-scottish.sql\n--\n-- Straight-forward query to select artists that appear in the scottish\n-- category.\n--\n-- This will return artists that appear in the scottish category, which\n-- includes artists that appear either exclusively in scottish or in\n-- BOTH scottish and any other category also.\n--\nselect a.artist_id, a.artist_name, x.genre_id\nfrom tbl_artist as a, tbl_artist_genre_xref as x\nwhere a.artist_id = x.artist_id\nand x.genre_id = 4;\n--snip--\n\n\n\n--snip--\n--\n-- file name: select-irish.sql\n--\n-- Straight-forward query to select artists that appear in the irish\n-- category.\n--\n-- This will return artists that appear in the irish category, which\n-- includes artists that appear either exclusively in irish or in BOTH\n-- irish and any other category also.\n--\nselect a.artist_id, a.artist_name, x.genre_id\nfrom tbl_artist as a, tbl_artist_genre_xref as x\nwhere a.artist_id = x.artist_id\nand x.genre_id = 5;\n--snip--\n\n

      The next files, all prefixed 'dump' will dump the record-sets returned by the above SQL queries into corresponding .csv files:

      \n--snip--\n--\n-- file name: dump-folk-only.sql\n--\n-- Dump all artists that appear ONLY in the folk category\n-- into folk-only.csv\n--\n.mode csv\n.output folk-only.csv\n.read select-folk-only.sql\n--snip--\n\n\n\n--snip--\n--\n-- file name: dump-folk.sql\n--\n-- Dump all artists that appear in the folk category\n-- into folk.csv\n--\n.mode csv\n.output folk.csv\n.read select-folk.sql\n--snip--\n\n\n\n--snip--\n--\n-- file name: dump-rock-only.sql\n--\n-- Dump all artists that appear ONLY in the rock category\n-- into rock-only.csv\n--\n.mode csv\n.output rock-only.csv\n.read select-rock-only.sql\n--snip--\n\n\n\n--snip--\n--\n-- file name: dump-rock.sql\n--\n-- Dump all artists that appear in the rock category\n-- into rock.csv\n--\n.mode csv\n.output rock.csv\n.read select-rock.sql\n--snip--\n\n\n\n--snip--\n--\n-- file name: dump-scottish.sql\n--\n-- Dump all artists that appear in the scottish category\n-- into scottish.csv\n--\n.mode csv\n.output scottish.csv\n.read select-scottish.sql\n--snip--\n\n\n\n--snip--\n-- Dump all artists that appear in the irish category\n-- into irish.csv\n--\n.mode csv\n.output irish.csv\n.read select-irish.sql\n--snip--\n\n

      In a real-world example, the hard-coded numeric genre identifiers in the above queries would be replaced by placeholders like '?' which would be replaced by actual values at run-time.

      \n

      Conclusion

      \n

      In conclusion, in my experience programming all manner of systems using Oracle, MySQL and SQLite databases, this method is the only one which doesn't take diabolical liberties with the rules of database normalisation.

      \n

      It may result in SQL queries which will make you scratch your head, but that is far more acceptable than doing stuff like trying to shoe-horn a many-to-many relationship into your database structure by other means.

      \n

      One of the most crucial aspects of using a high-end RDBMS like Oracle, MySQL or SQLServer, is the need to get as much data selection done by the server as possible.

      \n

      This is because the server is a big fat box in a cupboard connected to your machine by a network infrastructure. It might be next door or on the other side of the world.

      \n

      It makes far more sense for the server to return to you those records, and ONLY those records you want, over the network.

      \n

      Any other strategy for implementing a many-to-many relationship is likely to result in you pulling stuff back to your machine which you are ultimately going to drop in some kind of loop. Slow and wasteful of bandwidth.

      \n

      In the example I have used, the cross-reference table was populated manually. In most real-world implementations the cross-reference table will be populated in response to records being added to the two outer tables, or in response to user-intervention using a client application. Often triggers are used to create the cross-reference rows.

      \n

      If you were authoring a music database application in which such a relationship exists between artist and genre, the user interface would probably provide a means for the user to decide which genres to plop artists into.

      \n

      I have used SQLite to demo this strategy. While SQLite is a great tool, it is a 'lite' tool that is designed for single-user applications, in particular embedded systems.

      \n

      If you are thinking of starting an airline and want to implement a world-wide seat booking application which will serve many concurrent users, needing complex transactional operations, don't use SQLite or your customer complaints are likely to exceed bookings.

      \n

      My example data definitions also contain no constraints for preventing orphaned rows. These are rows in a table containing a foreign key where no record exists in the table identified by the foreign key. Because in my example I load the 'parent' tables before I load the table which contains foreign keys to both of those tables, there is no risk of creating orphaned rows.

      \n

      Most RDBMS systems include a mechanism for what is called 'cascaded deletes', that is, when deleting a row from a parent table, any row in a table containing a foreign key for that row, a 'child' row, will also be deleted, preventing 'orphaned' records.

      \n

      Applying this to the above example, deleting 'Runrig' from the artists table would also delete all rows from the artistgenrexref table with the identifier for 'Runrig'.

      \n \n

      If any queries result from this show about any of the terms I might have very casually scattered about relating to database theory, assuming I know the answers, I can do more shows about those.

      \n

      Maybe one about SQLite in particular.

      Nikola - The Static Web Site and Blog Generator - https://getnikola.com

      \n

      Note: Please see developer notes below

      \n

      What is it? A Static Website and Blog Generator based on Python.
      What is a Static Website Generator? It generates posts and pages via commands. You edit those posts and pages in a text editor, then run a command to build the site, and finally, deploy/upload the generated html etc files to your webhost.
      That sounds kinda old school are you sure thats web 3.0? Its old and new school. Nikola gives you CMS like features without the overhead of the database server and page rendering engine.
      How can I install it? Use PIP and follow the handbook on the getnikola.com website. NOTE: Python 2.6 or newer or Python 3.3 or newer is required

      \nsudo pip install nikola\nsudo pip install nikola[extras]\n

      You should be good to go if you can enter nikola help in a terminal and get a list of nikola commands.
      Lets create our skeleton website:

      \nnikola init mysite \n

      You will need to answer some questions now (NOTE a directory to cd into called mysite will be created if you issue mysite.. You should enter your domain name instead - mysite is just an example).
      The questions it asks will help populate the conf.py file in the mysite directory.

      \nSite Title: \nSite Author:\nSite Author Email:\nSite Description:\nSite URL:\nLanguages to support: (default en)\nTime zone: \nWhich comments system to use:\n

      Once complete your site will be created and in the directory you named the site as - in my case, mysite.
      cd into that and take a look at the files with ls.
      you will have:

      \n
        \n
      • conf.py - your configuration file
        • \n
      • files - where you will place images etc and reference them in blog posts and pages
        • \n
      • galleries - where you can serve up images in a gallery
        • \n
      • posts - where your blog posts go
        • \n
      • stories - where your pages go
        • \n
      \n

      Lets create a blog post.

      \nnikola new_post\n

      Type in the title of your blog post and hit enter. I will use foobar in this example
      It will report the new post is in posts/foobar.rst
      fire up your text editor and edit that file.

      \n

      There is a header area at the top of the file - most of it is already filled in and you wont need to change it but you should add a Tag because you can see posts by Tag once the site is generated and it gives your readers a way to find all items on that subject. These are separated by commas so enter as many or few as you like. Enter a Description in the Description area.
      Now move into the Write your post here area and go to town - erase that or it shows up in your post.
      You should read the page on ReStructuredText here: https://getnikola.com/quickstart.html but also just look at the source by clicking 'Source' on the getnikola website and you can see the markup they used. Some basics are

      \n*word*\n
      for italics, 
      \n**word**\n
      for bold, a single * space item for bullet points and for hyperlinks 
      \n`Tree Brewing Co: <https://treebeer.com/>`_.\n
      a Tree Brewing Co hyperlink which will bring you when clicked to treebeer.com. Lastly issue: 
      \n.. image:: /files/imagefilename.jpg\n
      to point to an image file that you have placed into the files directory.
      Ok lets say you are done your post, save it and exit. Lets now build your site and fire up the built in webserver to display it. 
      \nnikola build\nnikola serve -b\n

      Your default web browser will launch and you will see your site with blog post. Savour the moment - you have just created your first blog post. Note all the generated files you would upload to your webhost are in the output folder.
      Ok so thats great but I want to add pages and have it in my navigation window Ok lets do that.

      \nnikola new_post -p\n
      Enter a name for it and press Enter. In my case I created MyPage

      It tells you your page is in the stories directory and shows you how it named the file. In my case its mypage.rst
      Open that in a text editor and compose the page - save it when complete.
      So that would be great but its not showing up in your navigation yet. You need to put that in your conf.py file.
      Open conf.py in a text editor, look for NAVIGATION_LINKS. Observe how the existing pages are linked and follow that format. Here is how I would add mypage: (/stories/mypage.html, MyPage), any page you create will show up in stories so dont forget to put that in the path.

      \nNAVIGATION_LINKS = {\n    DEFAULT_LANG: (\n        (\"/archive.html\", \"Archive\"),\n        (\"/categories/index.html\", \"Tags\"),\n        (\"/rss.xml\", \"RSS feed\"),\n        (\"/stories/mypage.html\", \"MyPage\"),\n    ),\n}\n

      Save that and rebuild your site.
      NOTE:: As of Today Nikola v7.0.1 requires a special command to include the new pages in navigation. This has been fixed in git but currently you must issue:

      \nnikola build -a\nnikola serve -b \n

      Now you are viewing it - nice work - you have a page now.
      This site seems a bit plain, how can I theme it? Glad that you asked - issue this command.

      \nnikola bootswatch_theme -n custom_theme -s slate -p bootstrap3\n

      Now you have set it to use the slate bootswatch theme. Review the bootswatch themes on: https://bootswatch.com/
      In order to let Nikola know to use this new theme you need to edit the conf.py file and look for THEME and change the value from bootstrap3 to custom_theme.
      Now issue these commands at the command line to view the changes:

      \nnikola build\nnikola serve -b \n

      You can modify the themes to your liking and there is guidance on changing the theme on the nikola website.
      There are ways to depoly your site via rsync or ftp commands in the conf.py file. There are also other things you can set in the conf file such as google analytics, add an embeded duckduckgo or google search engine, specify options for the image galleries etc.
      More things you can do to spify up your posts / pages are to do with using shortcode like sytax for ReStructuredText. You can embed soundcloud, youtube videos etc - here is a list of these: https://getnikola.com/handbook.html#restructuredtext-extensions

      \n

      I hope this helps you get started on using Nikola and hope you enjoy using it as much as I do.

      \n

      Some small corrections:

      \n
        \n
      1. it is recommended to use a virtualenv, `sudo pip` can be dangerous
        2. \n
      2. `pip install nikola[extras]` is enough, no need to do both steps
        3. \n
      3. new pages can be created with `nikola new_page`, too (both ways are equally supported)
        4. \n
      4. \n missing quotes around \"MyPage\" in example navbar codeFixed
        5. \n
      5. you can get rid of /stories/ if you change PAGES[*][1] from \"stories\" to an empty string.
        6. \n
      6. bootswatch themes are not everything, there is also install_theme that uses a more varied collection from https://themes.getnikola.com/
        7. \n

      \n\n\n\n

      \nThree out of four of us liked this book, and we all had some good things to say about it. While it's true that this is an entertaining story set in a super hero world, we found it it more amusing and more thought provoking than your average super hero story.\n

I think it is fair to say that these security agencies felt they were given a mandate to do anything as long as it stops the attacks, and thus was the overwhelming attack on privacy moved to a whole level higher.

      \nA ramble about stars, by a geeky chap who resides on planet Earth. This episode\nis entitled a wee dot on a dark sky.\n

      \n

      \nI comment briefly on why it's remarkable\nthat the night sky is dark. I then go on to talk about the colour of stars,\nwhich we can just perceive with the naked eye. To learn more you need to use\na prism, or, as professional astronomers prefer, a diffraction grating to\nobtain a spectrum of a star. I talk a little too much about the mathematics\nof diffraction gratings but eventually get back to talking about\nspectrum of the Sun which in overall shape is very close to what physicists\ncall a black body spectrum (https://en.wikipedia.org/wiki/Black_body)- the spectrum any object will have at a given\ntemperature. Astronomers and physicists prefer to measure temperature\nin units of kelvin (https://en.wikipedia.org/wiki/Kelvin),\nand to convert to it you only need to add 273 to the\ncelsius temperature. Conversion from Fahrenheit is left as an exercise\nto the listener.\n

      \n

      \nThe Sun shows spectral lines, specifically dark lines on the broad spectrum\ncalled absorptions lines. This is caused by atoms in a cooler layer of gas\n(called the chromosphere) that's just above the bright surface of the Sun\n(called the photosphere). In fact, Helium is named as such because it was\nfirst discovered by its absorption lines in the solar spectrum (Helios\nis Greek for Sun). Many other elements can be found in the spectrum of\nthe Sun and other stars, but most of the mass of all stars is made up\nof hydrogen and helium.\n

      \n

      \nThe temperature of a star is correlated with colour, with blue stars being\nhotter than red stars. This was originally measured by astronomers by\nsomething called colour or B-V (B minus V) index.\n

      \n

      \nThe luminosity of a star is the rate\nat which it emits energy as light, and can be measured in the same units\nas light bulbs, i.e. watts (W). But to estimate the luminosity we need\nto know the distance to a star which, for nearby stars, can be \nfound by the parallax method. By plotting colour index (a proxy\nfor temperature) against luminosity we can form a key piece of empirical\nevidence - the Hertzsprung Russell diagram: https://en.wikipedia.org/wiki/Hertzsprung%E2%80%93Russell_diagram \n

      \n

      \nIt turns out that our nearest star - the Sun - is quite unremarkable. It is neither very hot or cool, nor\nvery bright or dim - it's a fairly typical star.\n

      SUMMARY

      \n

      In this episode, the HPR_AudioBookClub reviews Down And Out In The Magic Kingdom by Cory Doctorow. You can download this AudioBook for free (or voluntary donation) from podiobooks.com. https://podiobooks.com/title/down-and-out-in-the-magic-kingdom/ and it's also available in just about every ebook format you can imagine on Cory's website craphound.com. https://craphound.com/down/?page_id=1625 and as a paperback through various booksellers. We found this AudioBook enjoyable and thought provoking. The general consensus that we seem to have reached is that while the book left the reader with many unanswered questions about the world in which the book was set, they are welcome questions. It's brain bending fun.

      \n

      FiftyOneFifty (the link-king) found some cool links relating to the Haunted House and how it works. Check these out!

      gigasphere wrote in to say,

      \n
      I listened to this book in the space of a couple of days mostly. At first it took some time to get into but then was quite enjoyable, however in the second half I started to find it a bit hard going. The story is told exclusively in the first person (I think that's right) and as the story went on I found it quite difficult not having external points of view or reference. This is probably also due to good story telling as the main Character Jules is also getting frustrated and is increasingly isolated. The book was interesting and unique even before you got to the plot line and aspects of the world the characters were living in. I would recommend the book as an example of an interesting method of story telling and I'm keen to pick up the other big Cory Doctorow book, \"Little Brother\".
      \n

      gigasphere's spoilers (Highlight to read)

      \n
      \n

      From having read the wikipedia page on Cory I can see that Down and Out in the Magic Kingdom, which is Cory's first novel, seems to have a trademark extrapolation with our own reality. The concept of backing up you mind and being brought back from the dead in a clone seems an excellent example of hyper-our-reality at the moment, but to then have everyone capable of being online using implants is also amazingly realistic when you consider the almost boom in wearables going on and the ubiquity of smartphones. I am reminded of the xkcd comic where the guy was having a USB port implanted.
      https://xkcd.com/644/
      The whuffie aspect of the book which replaces money, reminds me a lot of the social media thing of being rated by how many 'followers' or 'likes' or may be even 'hits' you get. This also oddly reminds me of the download stats discussion on the mailing list at the moment.
      I'm not sure I'll add much to the overall discussion of the book from here as my no spoiler summary really rounds up the book for me. I would have liked to have a broader telling of the story, particularly from Lil's perspective, but the restrictions placed on the story also work to make it great, in that you are forced, as in real life, to view the world through only one person's eyes.

      • FiftyOneFifty was slightly disappointed by his German style Doublebock, FIREMAN'S BREW: Brunette. He says it's an unprepossessing brew, but perhaps worth it for fans of beer made with chocolate malts. Not very sweet for a dopplebock, and without much hops note except for a slight spicy kick, despite a general thinness in the flavor, it has enough cocoa flavor to satisfy fans of beers made with chocolate malt, at least until they find a better one.

      OUR NEXT TWO AUDIOBOOKS

      \n

      Revolution Radio by Seth Kenlon
      https://aesdiopod.com/books/

      \n

      AND

      \n

      Street Candles by David Collins-Rivera
      https://www.cavalcadeaudio.com/stardrifter.html

      \n

      We're really excited about these two AudioBooks because both of these authors are HPR community members! We're assigning both at once because one is pretty short, and one is pretty long. We were a little worried that people might not finish Street Candles in time to participate, and we think this scheme may buy participants the time they they/we need.

      EVA - The Rules for Extravehicular Activity

      \n

      Here I dip into the NASA experience of and rules for Extravehicular Activity, prompted at first by watching a film called The Europa Report, directed by Sebastian Cordero (2013).

      \n

      WARNING - THIS PODCAST CONTAINS SPOILERS

      \n

      While I have some gripes about the film, I was impressed by its general failfulness to the science

      \n
        \n
      • It thought to find life on Europa, a moon of Jupiter considered by real exobiologists and planetary scientists to be a good candidate
        • \n
      • Neil deGrasse Tyson made a cameo appearance
        • \n
      • The portrayal of Europa's geography and character
        • \n
      • Having to drill through the ice to get at the sea below
        • \n
      • The behaviour of the crew as scientists and engineers
        • \n
      \n

      Science consultant on the film was Kevin Hand, an astrobiologist and expert on Europa at NASA's Jet Propulsion Laboratory

      \n

      To my mind, the scientists were behaving like scientists and the engineers behaved like engineers. To follow along it might help to recall their names

      \n
        \n
      • Captain - Willam Xu
        • \n
      • Pilot - Rosa Dasque
        • \n
      • Chief scientist - Daniel Luxembourg
        • \n
      • Marine biologist - Katya Petrovna
        • \n
      • Junior engineer - James Corrigan
        • \n
      • Chief engineer - Andrei Blok
        • \n
      \n

      All was going scientifically until the director drove the plot forward with two EVA incidents

      \n

      EVA-1 : Flash back episode, engineers James and Andre go out to fix a failed communications circuit

      \n
        \n
      • Andre rips his suit
        • \n
      • James gets squirted with rocket fuel
        • \n
      • Only one astronaut survives
        • \n
      \n

      I have problems with this because it's just too clumsy for trained professional astronauts. Where are the decontamination procedures, the tethers, the special tools?

      \n

      EVA-2 : Down on the surface, Marine biologist Katya decides to walk out alone

      \n
        \n
      • Tourtured debate in the ship
        • \n
      • Of four able and expendable crew members, none go with her
        • \n
      • Katya does not come back alive
        • \n
      \n

      With this I am shouting at the screen \"No Way! Where's the fracking operating manual? No one goes EVA on their own\"

      \n

      So, that is why I researched the NASA rules for Extravehicular Activity. And I found that none of these events would have happened the way they were shown, had the crew, who were so professional in every other way, followed the NASA procedures.

      \n

      The two astronauts issue

      \n
        \n
      • The most recent occasion where an astronaut went solo EVA was in 1971, when David Scott stuck his head out of the airlock of Apollo 15.
        • \n
      • Most recent before that was in 1966, when Buzz Aldrin went EVA from Gemini 12 (Gemini craft only had two crew).
        • \n
      • Since 1971, there have been 358 space walks and every single one has had two crew.
        • \n
      • I found no written regulation, but de-facto, nobody leaves the spacecraft alone.
        • \n
      \n

      NASA procedures

      \n

      NASA documents on the internet discuss in exhaustive detail all considerations for EVA. What I present is a cherry-picked handful. I could not cover all of it

      \n
        \n
      • reasons for EVA
        • \n
      • alternatives
        • \n
      • planning
        • \n
      • hazard mitigation
        • \n
      • procedures for safe conduct
        • \n
      • fall-back procedures
        • \n
      • failure handling
        • \n
      • accident control
        • \n
      \n

      International Space Station (ISS) EVA Procedures Checklists

      \n
        \n
      • Presuming that all the equipment maintenance checks, and readiness checks have alread been done
          \n
        • 30 minutes of Airlock preparation and testing
          • \n
        • 30 minutes of changing components for the suit to fit the astronaut
          • \n
        • 170 minutes of EVA-Prep
          • \n
        \n
        • \n
      • Then you are ready to depressurise and leave the airlock
        • \n
      • EVA might last 2 - 8 hours
        • \n
      • Post EVA
          \n
        • 30 minute procedure to take the suit off
          • \n
        • 10 minute procedure to disconnect internal equipment
          • \n
        • Recharge & maintain the Extravehicular Mobility Unit (EMU)
          • \n
        • Clean & maintain the Suit
          • \n
        \n
        • \n
      \n

      Although this podcast is about EVA, it does reference the science in a film that I enjoyed and respect very much, so here is a gem that I only came across while researching the landing site. In the scientific journal Nature, Volume 479, 16 November 2011, Britney Schmidt et al, of University of Texas, Austin, published a paper titled \"Active formation of 'chaos terrain' over shallow subsurface water on Europa.\" In the paper these authors suggest that in the Conemara zone of the Chaos Terrain, an area on the surface of Europa, the ice may be as little as 3 km thick. Then in the film the Conemara Chaos was the targetted landing zone and the drill broke through the ice at a depth of 2800m.

      \n

      Well there is one more thing that the podcast says, but it is the ultimate spoiler. So if you have not already listened to the podcast, I highly recommend that you watch the film first.

      Today, the most common way of providing security in giving access to data or systems is through the use of passwords. Practically every online site now expects you to create an account with a password, which will let you post comments, order products, conduct business, or just post to social media. The implication is that insisting on passwords provides some level of security. Now, following on our last tutorial we should ask a few questions about just how effective this measure is, since someone posting in your name to Twitter is significantly different from someone accessing your bank account. And since the assets being protected are very different, it would be reasonable to approach the problem of security somewhat differently in these cases. But given the ubiquity of passwords as the authentication for online accounts, we need to look at the security involved. Note that I am approaching this from the standpoint of the owner of the site in question for this tutorial, and will follow up with a look at your own role in this.

      In Statistics there are generally speaking two types of analysis, broken down between Descriptive and Inferential statistics. The difference has to do what what claims you are making about the data. If you are simply stating something about the data (e.g. there were more men than women in the sample) that is descriptive. But if you make a claim that something is not likely to occur by chance, for instance, or that something is statistically significant (and both of those statements are essentially the same thing) then you are in the realm of inferential statistics.

      Virtual Network Computing
      From Wikipedia, the free encyclopedia
      \n
      In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.
      VNC is platform-independent – There are clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa.
      VNC was originally developed at the Olivetti & Oracle Research Lab in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License.
      There are a number of variants of VNC which offer their own particular functionality; e.g., some optimised for Microsoft Windows, or offering file transfer (not part of VNC proper), etc. Many are compatible (without their added features) with VNC proper in the sense that a viewer of one flavour can connect with a server of another; others are based on VNC code but not compatible with standard VNC.
      VNC and RFB are registered trademarks of RealVNC Ltd. in the U.S. and in other countries.

      In today's show, Philip Newborough interviews fellow members of Lincoln LUG. Each interviewee is asked 3 simple questions:

      1. What was your first experience of Linux?
        2. \n
      2. What distro and desktop environment/window manager are you currently using?

      \nRight now for most of us the key to any security in our online life is the degree of entropy in our passwords. So what is entropy, and how does it affect our passwords?\n

      \n

      \nEntropy is in general the degree of randomness or disorder in any given system. Sometimes it is very easy to assess, such as a password of 1234, which all too many people use. Because it is a simple sequence, there is no real randomness at all, and would be quickly guessed. And as we saw in the last tutorial, such passwords are quickly discovered in a dictionary attack. There are things you can do to make it less likely that your password will be cracked and used against you. - For more go to https://www.zwilnik.com/?page_id=530\n

      \nSmaltz Brewing Company - He'Brew (The Chosen Beer) Hops Collection\n

      \n

      \nDavid's Slingshot - Pours golden, like an American lager, large head that subsides, rye aroma. Blend of multi-grain malts, an emphasis on hops w/o being excessively hoppy. Citrus taste from the hops. Malts: Specialist 2-row, Carmel Pils, Rye Ale, Crystal Rye, Vienna, Wheat, Flaked Oats Hops: Cascade, SAAZ, Summit, Citra, Crystal\n

      \n

      \nGenesis Dry, so dry you could be excused for wanting a glass of water to go with your beer. Bready, not biscuity, like a fresh sourdough loaf, almost makes you want to spread butter over your beer. Just enough hops to be interesting rather than annoying. Just a little sweet on the back end, so subtle you'll likely miss it on the first sip. Watery mouth feel. 5.5% ACL. Malts: Specialty 2-row, Munich, Core Munich 40, Wheat, Dark Crystal Hops: Warrior, Centennial, Cascade, Simcoe\n

      \n

      \nBittersweet Lenny's R.I.P.A. Double Rye (an ode to comedian Lenny Bruce). Pours very dark amber, small head. Aroma of sweet rye bread. Sweet honey taste w/o being cloying, washed away by the hops. Strong rye flavor, much more than Slingshot. Malts: 2-row, Rye Ale Malt, Torrified Rye, Crystal Rye 75, Crystal Malt 80, Wheat, Kiln Amber, Core Munich 60 Hops: Warrior, Cascade, Simcoe, Saaz, Crystal, Chinook, Amarillo, Centennial\n

      \n

      \nHop Manna IPA Pours medium amber with a good head. Little distinct aroma. For the hops enthusiast who doesn't want other flavors getting in the way, but still not so hoppy that the hops get in the way of the hops. Hoppy enough to satisfy most hops heads without making your tongue feel like it is under assault from the Hop High Command. Malt: Specialty 2-row, Wheat, Munich, Vienna, Core Munich 60 HOPS: Warior, Cascade, Citra, Amarillo, Crystal, Centennial Dry Hop: Centennial, Cascade, Citra\nEven though hoppy beers aren't my preference, Smaltz/He'Brew were 4 out of 4 winners. If you see this brand, grab it with both hands. Even if I hated the beer, I'd be a fan because each bottle lists the malts and hops, giving the home brewer a shot at replicating the brew and the expert consumer a hint of what the beer is going to taste like before purchasing.\n

      The Banana Pi - First Impressions

      \n

      They say duplication is the sincerest form of flattery, substitute the word of your choice for 'duplication'.

      \n

      The Banana Pi is made in China and bears an uncanny resemblance to the Raspberry Pi.

      \n

      Not just the name, the board is fractionally larger, some of the features on the board are similarly placed:

      \n
        \n
      • 26-pin GPIO
        • \n
      • 3.5mm analogue audio jack
        • \n
      • RCA composite video jack
        • \n
      • SD card slot
        • \n
      \n

      There are things the RPI does not have:

      \n
        \n
      • Power button
        • \n
      • uBoot button
        • \n
      • Microphone
        • \n
      • USB-otg port (otg = on-the-go, a bi-directional USB port)
        • \n
      • SATA connector
        • \n
      \n

      The processor is a dual-core running slightly faster than the Raspberry Pi, although to be fair, of course, the RPI can be over-clocked.

      \n

      The Banana Pi has twice the RAM and a dual-core processor.

      \n

      The SoC is the ARM Allwinner A20.

      \n

      Getting my Hands on a Banana Pi

      \n

      My first Banana dropped through the letterbox a couple of days ago.

      \n

      Thanks to some kind soul on the Raspberry Pi Facebook group who described the connectors on the edges of the board I narrowly avoided plugging the power supply into the USB-otg port. The power micro-USB is on the underside of the board between the SATA power and data connectors which are on the upper side of the board.

      \n

      Can't really say much about it because I can't actually see the build quality, but it feels nice. The PCB is fractionally thinner than the RPI.

      \n

      Problems

      \n

      I had an initial struggle to find a download link for any images.

      \n

      The downloads page of lemaker.org has a two row table on it which appears to be upside-down and it has links to Google-drive, two different public DropBox links, a MS One-Drive link, and something I didn't initially find, an FTP link.

      \n

      Both of the DB links are duff because they have suspended the account because of excessive traffic.

      \n

      This is the FTP download link:

      \n
      https://filez.zoobab.com/bananapi/mirror/
      \n

      Available Images

      \n

      When I found the FTP page I grabbed images for:

      \n
        \n
      • Arch Linux
        • \n
      • Bananian-latest
        • \n
      • Lubuntu
        • \n
      • Raspbian
        • \n
      \n

      I downloaded and extracted all of these images to my Debian desktop machine and tried to write and boot them in succession.

      \n

      The first I tried was Arch, on the assumption that would not have a desktop installed.

      \n

      After writing the card I looked at it on my Debian machine with parted and it appeared to have two partitions. As with the Raspberry Pi there is a small FAT16 partition and a bigger ext4 partition.

      \n

      The FAT partition contained the same files as the Raspberry Pi:

      \n
        \n
      • config.txt
        • \n
      • cmdline.txt
        • \n
      • kernel.img
        • \n
      \n

      And some others I can't remember.

      \n

      In addition it contained:

      \n
        \n
      • uEnv.txt
        • \n
      • uImage
        • \n
      \n

      It appears uEnv.txt is equivalent to the Raspberry Pi cmdline.txt file, and uImage is, of course, the kernel.

      \n

      So oddly it has the files for the RPI and it's own in the FAT partition.

      \n

      Then I tried Bananian, and this appears to be Debian Wheazy for ARM.

      \n

      Similar story with the FAT partition.

      \n

      It is a very minimal installation which has little more than the Linux Standard Base (LSB) packages. I like this because I like to have control.

      \n

      Sound and Stuff

      \n

      I found a review from April this year that said the sound driver snd-bcm2835 was not available. At the name snd-bcm2835 my heart sank because I expected the BPI to have the same stuttering text-to-speech problems as the RPI.

      \n

      Not expecting much I did, as root:

      \n
      apt-get install alsa-base alsa-utils
      \n

      Looking through /lib/modules/... blah blah I found a driver called:

      \n
      snd-aaci.ko
      \n

      I did:

      \n
      modprobe snd-aaci
      \n

      And then:

      \n
      speaker-test
      \n

      And I got pink noise!

      \n

      Next I did:

      \n
      apt-get install espeakup\nupdate-rc.d espeakup defaults\nmodprobe speakup_soft
      \n

      And speakup burst into life with no stuttering!

      \n

      Immediate Conclusions

      \n

      The online community and code-base for the Banana Pi is not yet very mature, and because the origin of the beast is China, a lot of what's out there is in Chinese.

      \n

      But it is growing. And after all, it took the RPI a while to take off and go ballistic.

      \n

      At the moment I would say the Banana Pi is not for the faint-hearted or the total newbie, although, a lot of newbie questions are generic and don't have machine-specific answers.

      \n

      The worst thing about the Banana Pi is, when writing emails about it, and these show-notes, typing the word 'banana' and knowing when to stop!

      \nThe second episode in a series on bare metal programming on the Raspberry Pi.

      My Coffee History

      \n

      I'm a coffee lover. I have tried many ways of making coffee.

      \n

      When I was a child my parents made their coffee in a percolator on the stove top. I remember how great it smelled though it tasted awful to me at that age.

      \n

      I have owned a variety of filter machines over the years, and these have also been available at the places I have worked. They seemed to do a reasonable job, but nothing special.

      \n

      One time I owned an all-glass Cona coffee maker, which was very fancy and expensive. It was too fragile for me and eventually met its end while being washed. I don't recall it making particularly wonderful coffee, but it would also make tea, which was a novelty.

      \n

      I made a number of visits to Indonesia several years ago. There are a lot of pretty good coffee beans available there but the way of making a cup of coffee is not really to my taste. A good dollop of ground coffee in a large cup with boiling water added and large quantities of sugar. Straining those coffee grounds out through your teeth is not a pleasant experience.

      \n

      As the fashion for the Cafetiere or French Press developed I acquired a number of these. Until recently these were all glass. I found I invariably broke them either by being over zealous when pressing down the plunger or being clumsy when washing them up. It's not a bad way of making coffee, but I have an alternative that I much prefer - the Moka Pot.

      \n

      Moka Pot

      \n

      A few years ago I bought a Bialetti Moka Pot. I had never heard of these before, but my son, another avid coffee drinker, pointed me to them. I bought a three-cup pot to start with. This is a small pot; the three refers to three 50ml espresso cups. I also bought a 9-cup pot which is much bigger.

      \n

      \"My
      Picture: My Bialetti 3-cup and 9-cup pots

      \n

      The pot consists of three main elements: a base which holds the water, a funnel which holds the ground coffee and the top which holds the coffee once made. There is a gasket and a metal filter on the underside of the top part to prevent coffee grounds entering.

      \n

      \"A
      Picture: A disassembled Bialetti

      \n

      The Bialetti is heated on a gas or electric stove and forces boiling water through ground coffee under steam pressure. It makes coffee similar to but not the same as espresso coffee.

      \n

      The base is filled with water just under the level of the pressure release valve.

      \n

      \"Bialetti
      Picture: Bialetti filled with water

      \n

      I use Italian coffee for the Bialetti since it seems to taste better than any others I have tried.

      \n

      \"My
      Picture: My current favourite coffee

      \n

      Once opened I keep my coffee in a vacuum container.

      \n

      \"Coffee

      The funnel is placed into the water-filled base.

      \n

      \"Bialetti
      Picture: Bialetti ready for coffee

      \n

      The funnel takes about two scoops of coffee

      \n

      \"Bialetti
      Picture: Bialetti being filled with coffee

      \n

      The pot is placed on the stove. I have a gas stove and so I use a trivet for stability. I have to take care that the gas flame is not too high or the handle will melt, as has happened in the past!

      \n

      \"Bialetti
      Picture: Bialetti in action

      \n

      You need to listen out for the bubbling sound the pot makes when the water has passed through the coffee into the top compartment. Letting the remaining steam pass through will over-heat the coffee which you do not want to happen.

      \n

      \"Coffee
      Picture: Coffee is brewed

      \n

      I make a cup of coffee consisting of one part coffee, one part cold milk and one part boiling water. This makes a large cup of pretty strong yet very smooth coffee which helps to wake me up each morning.

      \n

      \"A
      Picture: A comforting brew - in the wrong cup!

      \n

      The Bialetti usually gets one use per day, after which it is washed up. Some purists say that it should only be rinsed out so that the coffee residues on the inside are not removed. I have not noticed any difference personally.

      As we are all human to some degree, we require sustenance. When on a roadtrip, this can prove to be challenging - but it is also an opportunity to save money and enjoy yourself!

      \nBringing Food\n---\n\n- Buying all your food on the road is a good way to empty your pockets\n- Convenience stores do not have your health in mind; their food is generally\n  over-salty or over-sugary\n- Stopping for snacks can add lots of extra time to a trip\n- A quick stop at the grocery store before your trip is not a bad idea\n        - Stock up on non-perishable snacks\n        - Nuts and trail mix are a classic for a reason. They're full of protein and\n          fiber, and easy to munch on in a vehicle\n        - Fruit are sweet, healthy, and also usually easy to eat in a vehicle.\n          Apples and grapes are super easy, bananas less so, and oranges are tricky.\n          You can pre-peel fruit to make it more accessible, but it won't last as long.\n- Water is important. Make sure to have a gallon jug with you, and refill as\n  necessary. I don't mind tap water, but if you're picky, there are water\n  filters designed for camping that are compact and quick. Keep yourself\n  hydrated!\n- Your options for variety of food increase a lot with a cooler\n        - Things like cheese and sandwich meats should do fine\n        - Make sure to fill it with ice or freezer packs when you set out in the\n          morning, and maybe during the afternoon depending on weather\n        - Check to see if your lodgings have refrigeration; your cooler will be\n          useless if you don't have something more substantial to use in-between\n          legs of your journey.\n  \n\nStopping To Eat\n---\n\n- Saving money and being efficient is all well and good, but roadtrips are not\n  all about getting from point A to point B.\n- A great way to experience an area is by ingesting a small part of it\n- Add an hour or two to your travel time for a meal stop\n- Pick lunch or dinner\n        - Lunch may suit your timetable better if you are an early riser\n        - Lunch menus often offer slightly less food for a reduced price\n        - Restaurants may be less crowded for lunches\n        - Dinner might be a better choice if you like waking and driving late\n        - Dinner menus are more comprehensive, but often more on the expensive side\n- Avoid chain restaurants all the time, but especially on a roadtrip\n- Local restaurants and eateries are usually found in downtown areas, away from\n  highways. They are well worth the diversion.\n- Different areas have vastly different cuisines, and trying new things can be\n  very rewarding. Crawfish: who knew?\n- Find something on the menu that you don't recognize, and eat it.\n- If you are a picky eater, try not to let your preconceptions stop you from\n  trying something. For instance, coconut soup is surprisingly unlike any other\n  coconut dishes that I've had.\n- Be polite, be patient. Many tourists are rude, and there is a chance that\n  the person helping you gets to deal with those tourists frequently.\n- Do not be afraid to ask questions. Figure out what you can, but ask for\n  clarification if something on the menu is unusual.\n- If you have food-based allergies or special dietary requirements, these might\n  not be accommodated in all areas. If you are a vegetarian or vegan, or are \n  allergic to gluten, peanuts, or dairy, your options may change drastically\n  depending on the region you are in.\n  - A little research into local restaurants  could help you determine which\n        places you can eat without stopping at each restaurant in town.\n- Overall, try to enjoy yourself. Roadtrips can be high-stress affairs, and a\n  meal break can do wonders to relieve some of the stress that's built up over\n  the day. Relax, and give yourself plenty of time to eat\n

      \nPreviously we looked at Public Key encryption, which is also called Asymmetric Encryption because it uses two different keys for the encryption and decryption. This allows us to solve one of the biggest problems in secure encrypted communication, which is key distribution. Because the public key can be freely distributed, you dont need to maintain security around the process of distributing keys. Symmetric encryption, on the other hand, relies on a shared key that is used for both encryption and decryption. An example of this is the one-time pad, where you printed up a pad of paper that contained various keys, and each one was used only once. As long as no one can get the key, it is unbreakable, but the big weakness was key distribution. How do you get the one-time pad into the hands of your correspondent? And you would need to do this with separate one-time pads for each person you needed to communicate with. These are the kinds of problems that made asymmetric encryption so popular. Finally, symmetric key crypto cannot be used to reliably create a digital signature. The reason should be clear. If I have the same secret key you used to sign a message, I can alter the message, use the shared secret key myself, and claim you sent it. - For more go to https://www.zwilnik.com/?page_id=650\n

      Unison is a file syncing/backup utility, similar to SyncBack on Windows, available in most repros.

      \n
        \n
      1. The graphical interface requires the installation of unison, and unison-gtk.. Unison may be installed w/o the graphical component, but all operations must be initiated from a system running the GUI.
          \n
        • Network backups require RSH or SSH to be installed on both machines
          • \n
        \n
        2. \n
      2. The standard wisdom seems to be the rsync does not do a true 2 way sync, i.e., to sync to the newest file version going both ways you would have to do rsync ~/LocalFolder you@server:/home/you/RemoteFolder then turn around and do rsync you@server:/home/you/RemoteFolder ~/LocalFolder. Add that to the fact that like cp, or scp, rsync requires separate commands for files with extensions, files without, and hidden files, creating a bash script for syncing files is more complex than creating a Unison profile.
        3. \n
      3. Step One: If, like me you are syncing only Documents, make your subfolder structure the same on both machines, ergo, if one PC has /home/you/Documents/recipe and second PC has /home/you/Documents/Recipes, edit your folder structure to be the same on both PCs to avoid duplicate files and folders
        4. \n
      4. Launch Unison and create a backup profile First use, create a profile
        \n
          \n
        • Name of profile
          \n
          • \n
        • Synchronization kind (Local, SSH, RSH, TCP)
          \n
          • \n
        • \"First\" Directory (you can browse your mounted volumes)
          \n
          • \n
        • \"Second\" Directory, if you chose Local
          \n
          • \n
        • Host Machine Name (or IP Address)
          \n
          • \n
        • User Name (If you haven't registered SSH keys, you will be prompted for a password on every synchronization.
          \n
          • \n
        • Check whether you want to use compression, (on fast networks or slow processors, compression may create more overhead than it's worth).
          \n
          • \n
        • Target directory (If it's on a remote server, you will need to type the full path, there is no browsing to the folder.)
          \n
          • \n
        • Tell Unison if either folder uses FAT (say an un-reformatted USB stick)
          • \n
        \n
          \n
        • If you are backing up to another system, Unison needs to be installed on both. If you are backing up to a server with no GUI desktop manager, you can install just the unison package without unison-gtk, but all the syncs will have to be initiated from the machine with a GUI. (Of course, if you back up to a remote volume that is mounted locally, it should be completely transparent to Unison). If you choose to sync via ssh (recommended), you will need ssh and ssh-server installed appropriately on each machine.
          • \n
        \n
        5. \n
      5. Select and run your profile.
          \n
        • The first time, expect to get a warning that no archive files (index files that speed up the synchronization scan) were found. They will be created on the first sync.
          • \n
        • Unison will look for differences between the files in the two selected directories. The differences will be displayed graphically, with arrows pointing left or right, indicating which directory contains the most current version of the file (by modification date). You can choose to merge files either left or right (a conventional backup), do a merge (i.e., Unison itself decides how to combine data from files with the same name (obviously, that could be messy), or to do a sync (ergo, the most current version of a file overwrites older version, regardless of location). Click \"Go\" to do a true sync.

      Open source product development most effective when social

      \n

      Benetech started out in the 90s without even understanding the meaning of the term open source. They just \"needed an easy way to interface with different voice synthesizers\" to develop readers for people who are blind and \"shared the code to be helpful.\"

      \n

      \n

      Sound familiar? Opensource.com started covering stories like in 2010 and they recur more often than you might think. Stories of people sharing the code to help others—but sharing code to get help developing better code. When code is open, a community has the opportunity to form around it.

      \n

      Read this interview about what Benetech CEO Jim Fruchterman learned by adopting open source philosophy and furthering technology-for-good.

      OpenStack product management: wisdom or folly?

      \n

      Two recent, excellent, blog posts have touched on a topic I've been wrestling with since May's OpenStack Summit: What is the role of the Product Management function, if any, in the OpenStack development process?

      \n

      The first article, \"Calling all 'User Landians' to lead OpenStack above the cloud,\" by Evan Scheessele, talks about the \"real user\" of OpenStack—those people that need to deliver a solution that brings some sort of value to their organization. The other article, \"Who's In Charge Here Anyway?…,\" by Rob Hirschfeld, speaks to the dynamics of how decisions—which OpenStack features are in in or out—get made in the OpenStack ecosystem.

      Giving Sub-Saharan African communities an online presence

      \n

      People in Sub-Saharan Africa face hurdles to get online. Despite some progress, the region lags behind in Internet connectivity due to the high costs of service and poor infrastructure, according to a recent World Economic Forum report.

      \n

      \n

      This digital divide means some African communities are underrepresented on the web. Without a well-developed online presence, misinformation about them can spread relatively unchallenged.

      Bash parameter manipulation

      \n

      I'm a great fan of using the Linux command line and enjoy writing shell scripts using the Bash shell.

      \n
        \n

      • BASH (or more usually Bash or bash) is the name of a Unix shell. The name stands for Bourne Again SHell, which is a play on words. Bash is an extension of the shell originally written by Stephen Bourne in 1978, usually known as SH.

        • \n

      • Bash was written as part of the GNU Project which forms part of the Linux Operating System.

        • \n

      • A shell is the part of the operating system that interprets commands, more commonly known as the command line.

        • \n

      • A knowledge of Bash is very helpful if you would like to be able to use the power of the command line. It is also the way to learn how to build Bash scripts for automating the tasks you need to perform.

        • \n
      \n

      In this episode we look at what parameters are in Bash, and how they can be created and manipulated. There are many features in Bash that you can use to do this, but they are not easy to find.

      \n

      As I was learning my way around Bash it took me a while to find these. Once I had found them I wanted to make a "cheat sheet" I could stick on the wall to remind me how to do things. I am sharing the result of this process with you.

      \n

      The version of Bash which I used for this episode is 4.3.30(1)-release

      \nSince April last year the text-to-speech using eSpeak in the Raspberry Pi\nconsole has stuttered very badly and regularly crashes the kernel.\n

      As part of Hacker Public Radio's continuing effort to showcase Creative Commons Works, we are proud to present GeekSpeak. GeekSpeak is produced as a radio show for community based station KUSP in Monterey CA, and rebroadcast as podcast, available from GeekSpeak.org. It is a generally a lighthearted and humorous general technology news show, with topics including electronics, computing, robotics, and green tech. Often guest speakers and authors from the technology world will come on for interviews. The shows are just about an hour long.

      \n

      The regular hosts are Bonnie Jean Primbsch, Lyle Troxell, Miles Elam, and Ben Jaffe (see GeekSpeak.org/geeks/for the full roster). You can often hear them thanking the \"Puppetmaster\" for letting them continue to use the name GeekSpeak. After broadcasting for several years, it was discovered the term \"GeekSpeak\" had been registered as a service mark by David Lawrence for a podcast of his own. You might remember Lawrence as the actor who played the character on \"Heroes\" with the telekinetic ability to physically manipulate other characters against their will.

      \n

      GeekSpeak has a long standing tradition of using Devo's \"Through Bein' Cool\" as intro music, so only those episodes that employ user contributed music instead are actually released Creative Commons. What you are about to hear, from the 1st of June of 2013, is just such an episode.

      \nRuth Suehle gave the next-to-last keynote at Ohio LinuxFest 2014 on 2014-10-25. In this talk she discusses the significance of open hardware and maker culture, and how this is something we all should participate in. Maker culture is an essential part of the free and open culture we belive in when we talk about open source. And we need to be vigilant to protect our values in the hardware space. As an example she tells us about Bre Pettis and Makerbot, which at one time were very open, but have turned aginst this value as they became more successful. In the final analysis, it is up to us to protect open hardware by voting with our dollars/euros/whatever.\n

      \nI have a laptop and I want it to use different configurations depending on where I am. If I’m on wifi at home, I don’t want my NAS mounted, but if I’m on a wired connection I do. If I’m at work I want to connect to various servers there. If I’m in the train I want to setup a vpn tunnel. You get the idea.\n

      \n

      \nMy solution to this was to approach it from the laptop and go out. So to look around and see what network I was on. There are a few ways to approach this, you could look at your IP address, the arp tables, try and ping a known server in each location. The issue with looking at an IP address is that most networks use Private Networks. Very soon you will find that the wifi coffee shop happens to have picked the same range as you use at home and now your laptop is trying to backup to their cash register.\n

      \n

      \nThen I was thinking that I’m approaching this problem from the wrong angle. Why not start with my public IP address range, which has to be unique, and work back from there to my laptop. From there I was planning on maintaining a look-up table of public IP addresses, along the lines of the GeoIP tools developed by MaxMind.\n

      \n

      \nBy Accident I found out that geoiplookup supports AS Number\n

      \n
      \nFrom WikiPedia: Autonomous System (Internet)
      \nhttps://en.wikipedia.org/wiki/Autonomous_System_%28Internet%29
      \nISP must have an officially registered autonomous system number (ASN). A unique ASN is allocated to each AS for use in BGP routing. AS numbers are important because the ASN uniquely identifies each network on the Internet.\n
      \n

      \nSo what that is saying is that every network in the Inter(connected)Net(work), must have it’s own unique AS Number. From there I was able to write a script to easily manage my laptops behaviour based on both location and connection type

      My Audio Player Collection

      \n

      I got broadband installed in my house in 2005 after I'd bought my first PC. I'd owned a lot of PCs before that, but they had all been cast-offs from the university I was working at, and I accessed the Internet via dial-up to my work.

      \n

      This was around the time I got sick of listening to the radio and first discovered podcasts, and so I decided I wanted a portable audio player (or MP3 Player as they tended to be called back then).

      \n

      Since then I have been listening to podcasts pretty much all of the time and have worked my way through a number of players. I thought it might be interesting if I chronicled the devices I have owned in the past 9-10 years.

      \nBeni read this article which lead to him trying out Slackware and being very\nimpressed by its simplicity.\n

      \n

      \nThat's why he asked mcnalu to do a HPR episode about Slackware, which is\nprobably the oldest Linux Distro that's still around and whose developer follows\na no-nonsense strategy and is very conservative when it comes switching to new\nstuff that comes up in the Linux world (like PAM or systemd)\n

      \n

      \nThe distro is one of the if not the most Unix-like Linux distro. It uses a BSD\nstyle init system instead of widely used sysvinit.\n

      \n

      \nBeni and mcnalu talk about the installation process, finding documentation and\nwhy the website is outdated.\n

      \n

      \nFurther they discuss the package manager and what it means that it doesn't\nresolve dependencies. They also explain why this isn't necessarily a bad\nthing and where to find binary packages.\n

      I really liked David Whitman's idea of doing a show on his birthday https://hackerpublicradio.org/eps/hpr1547/index.html, so I'm borrowing the idea.

      \n

      This show is being released on my 65th birthday, and I decided to use this opportunity to tell you about my long experience with computational devices as part of the series "How I Found Linux". Thinking about what I want to cover, I realise that it might be quite a lot, so I'm organising the shows into a collection of short episodes.

      \n

      I have been thinking about doing this for a while. Up until now I was concerned that it would be a bit self-indulgent, but I have been advised to just go ahead and do it. I hope you find the shows interesting.

      systemd For Learner Drivers

      \n

      A graphic to help out: hpr1672.svg

      \n

      This is a subject that attracts controversy, but I am not today going to be controversial, I hope. Many Linux systems are moving away from SysV Init and adopting systemd instead; both Linuxes that I use, Fedora and Mint have adopted systemd, and I understand that Debian has now forked to allow both sides of the argument to have their way. I am not going to get into the debate here. My personal stance is that I see both sides of the argument and I will continue to perch on top of the fence until systemd either proves itself or fails to do so.

      \n

      In this HPR I am going to try to fill a gap that I have seen in the systemd discussion; that is - how to operate it. I am not an expert on systemd, I have just tried to work it, and in doing so I have fished around in my file system and in the documentation. If you want to know what I found, then keep on listening. By way of opening I will remind myself, and you also, what systemd is replacing.

      \n

      SysV initd works with runlevels, the most common being

      \n
        \n
      • 5 for graphical multiuser networked
        • \n
      • 3 for cli multiuser networked
        • \n
      • 1 for single user
        • \n
      • 6 for reboot
        • \n
      • 0 for halt
        • \n
      \n

      In moving to a runlevel, unwanted services are shut down and wanted services are started up. For most users on most systems the most appropriate default runlevel is 5 giving multiuser, GUI & networking. Services can be started and stopped on demand by inetd.

      \n

      systemd works differently. It has target units. For most users on most systems the most appropriate default target is the graphical.target, which does a similar thing to runlevel 5 . Units are configured by unit configuration files. These files may start other units and stop other units. They can impose sequence and dependancies. There is a lot of cascading going on, with unit launching unit launching unit. Units also can be started and stopped on demand by systemd.

      \n

      Units

      \n

      The term Unit refers to a resource that systemd is taking under its control. There are 12 different types of Unit.

      \n
      \n
      systemd.service
      \n
      that starts/stops daemons
      \n
      systemd.socket
      \n
      activates network connections
      \n
      systemd.device
      \n
      activates kernel devices
      \n
      systemd.mount
      \n
      controls mount points
      \n
      systemd.automount
      \n
      provides on-demand mounting of file systems
      \n
      systemd.swap
      \n
      does for swap what systemd.mount does for filesystems
      \n
      systemd.scope
      \n
      starts/stops external processes
      \n
      systemd.target
      \n
      groups of services akin to init level 3, init level 5
      \n
      systemd.snapshot
      \n
      saves/restores the momentary state of other units
      \n
      systemd.timer
      \n
      triggers units based on date/time
      \n
      systemd.path
      \n
      trigger units based on changes in file system objects
      \n
      organises units in a hierarchical tree of cgroups, for resource management purposes
      \n
      \n

      Units files called by systemd live in /etc/systemd/system. But these are symbolic links to the real ones stored in /usr/lib/systemd/system

      \n

      There is a parallel /etc/systemd/user structure which does not seem to do anything on my computers, so I work for now like its not there.

      \n

      There is also a /run/systemd/system structure which appears to contain runtime configuration files with names like session-xxxx.scope. These are the unit type for external processes.

      \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
      Table 1. Directory structure for systemd
      PathDescription
      /etc/systemd/systemLocal configuration
      /etc/systemd/userUser configuration
      /run/systemd/systemRuntime units
      /usr/lib/systemd/systemUnits of installed packages
      \n

      Directives

      \n

      The next thing we need is Directives.

      \n

      The unit configuration files contain directives to start/stop a unit, and directives that cascade to other unit configuration files that start/stop dependant units. Directives may impose conditions on whether or when to call a unit. There are a whole bunch of different directives listed in man systemd.unit. These are a few.

      \n
        \n
      • Requires= list of units to start. If any required units fail then abort this one
        • \n
      • Conflicts= list of units to stop
        • \n
      • After= the order in which units will start
        • \n
      • Before= the order in which units will start
        • \n
      • Wants= list of units to start. If any fail just continue anyway
        • \n
      \n

      As well wanted units listed by the WANTS directive, there may also be a 'wants' directory below the unit directory. So the unit conf file /etc/systemd/system/default.target will cause two further unit conf files to be read in from the /etc/systemd/system/default.target.wants/ directory.

      \n

      Each required unit and wanted unit from the directives, as well as those in the wants directory are added to a job queue. If directives cascade to other unit files containing more directives then all of these dependences are also added to the job queue. A directive may start or stop another unit, or that change the detail of a job already in the queue. All directives ultimately cascade down to starting or stopping one of the base units in /usr/lib/systemd/system.

      \n

      To get a feel for how this all pans out in practice I will walk us through the cascade of unit files from bootup.

      \n

      From Bootup

      \n

      First, the default.taget is activated, which on my system is just a link to graphical.target

      \n

      graphical.target

      \n[Unit]\nDescription=Graphical Interface\nDocumentation=man:systemd.special(7)\nRequires=multi-user.target\nAfter=multi-user.target\nConflicts=rescue.target\nWants=display-manager.service\nAllowIsolate=yes\n

      Cascades to

      \n
        \n
      • start multi-user.target
        • \n
      • start display-manager.service
        • \n
      • stop rescue.target
        • \n
      \n

      Also we have a wants directory /etc/systemd/system/graphical.target.wants/ that

      \n
        \n
      • starts accounts-daemon.service (for logging)
        • \n
      • starts rtkit-daemon.service (for realtime scheduling)
        • \n
      \n

      multi-user.target

      \n

        • \n
      • stop rescue.target (again)
        • \n
      \n

      Also we have a wants directory /etc/systemd/system/multi-user.target.wants/ that

      \n- abrt-ccpp.service\n- abrtd.service\n- abrt-oops.service\n- abrt-vmcore.service\n- abrt-xorg.service\n- atd.service\n- auditd.service\n- avahi-daemon.service\n- chronyd.service\n- crond.service\n- cups.path\n- irqbalance.service\n- libvirtd.service\n- mcelog.service\n- mdmonitor.service\n- NetworkManager.service\n- nfs.target\n- remote-fs.target\n- rngd.service\n- rpcbind.service\n- rsyslog.service\n- smartd.service\n- vmtoolsd.service\n

      display-manager.service

      \n

      graphical.target also cascaded to display-manager.service which is not present on F20 so I guess we don't need it.

      \n

      basic.target

      \n

      So multiuser.target cascaded to basic.target, which itself cascades to

      \n- sysinit.target\n- sockets.target\n- timers.target\n- paths.target\n- slices.target\n- firewalld.service\n

      sysinit.target

      \n

      basic.target cascaded to sysinit.target which itself cascades to

      \n- local-fs.target \n- swap.target\n- dmraid-activation.service\n- iscsi.service\n- lvm2-monitor.service\n- multipathd.service ( which looks like all the file system daemons)\n

      sockets.target

      \n

      basic.target also cascaded to sockets.target which itself cascades to

      \n- avahi-daemon.socket\n- cups.socket\n- dm-event.socket\n- iscsid.socket\n- iscsiuio.socket\n- lvm2-lvmetad.socket\n- rpcbind.socket\n

      End point

      \n

      Now we start reaching the end-points of this trail at

      \n- systemd.sockets\n- systemd.timer\n- systemd.path\n- systemd.slice\n- systemd-fstab-generator\n

      By the time all of that has finished, if I type the command

      \n

      # systemctl list-units --type service

      \n

      I see that 58 services are listed as running

      \n

      Running and Configuring Services

      \n

      If we are going to work with systemd we will have to give it instructions. In systemd parlance

      \n
        \n
      • active = running, currently in use
        • \n
      • loaded = enabled, available for use
        • \n
      \n

      These terms crop up in the output from commands

      \n

      Many instructions are given to systemd by the systemctl command.

      \n

      Now to compare line up some common SysV init tasks with their systemd equivalent

      \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
      Table 2. SysV init commands and their systemd equivalents
      commandSysV Initsystemd
      Check status# service bluetooth status# systemctl status bluetooth
      Start# service bluetooth start# systemctl start bluetooth
      Stop# service bluetooth stop# systemctl stop bluetooth
      Enable# chkconfig --level 35 ntpd on# systemctl enable ntpd
      Disable# chkconfig --level 35 ntpd off# systemctl disable ntpd
      \n

      Journalctl Logging

      \n

      Much has been said about the desirability or otherwise of binary logs, but systemd gives us these so we had better know what to do with them.

      \n

      Journal instructions are given to systemd by the journalctl command

      \n
      \n
      To view all log entries in one go. This is verbose, mine came out at ~9000 lines
      \n
      # journalctl
      \n
      To view from a specific date
      \n
      # journalctl --since=\"2014-05-07\"
      \n
      To view kernel logs
      \n
      # journalctl -k
      \n
      To follow a log in realtime ... and then to close
      \n
      # journalctl -f
      ...
      # ctl-c
      \n
      To view log entries associated with a given PID
      \n
      # journalctl _PID=1
      \n
      To view log entries associated with a given service
      \n
      # journatlctl -u bluetooth
      \n
      \n

      Interrogating the system

      \n

      More systemd information

      \n
      \n
      Get/Set system information. Works like uname, but is more verbose
      \n
      # hostnamectl
      \n
      Get/Set timezone & timedate info
      \n
      # timedatectl
      \n
      \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n

Since OSP is the most closely related to HPR, I'm going to start with that. OSP started as a shared hosting gift for new developers. The idea was I could make people accounts on Dreamhost and they could test the latest free software. Since it wasn't a business, I didn't really promote it. It never took off. I had a few people in Wisconsin make accounts, but they barely used them. It's not really important why that idea failed, but eventually it just became a place for me to talk tech. lnxw48 aka lnxwalt is our current systems administrator and occasionally writes pieces for the site. Like all of our sites, we are always looking for contributors! \n

This means a lot of things. First it means, making sure online sports viewing works in free formats. It also means that there are free software fantasy sports implementations and that sports journalism happens under free culture licenses. Sportazine is a weird beast because we partnered with JMP Enterprise. \n

I'll probably talk a lot more about free software on the reboot, because it's not a topic Tom really cares much about. Tom is a GNU/Linux user, but he refuses to use anything but Skype or Hangout for recording the shows. I'll probably have on musicians that we wouldn't otherwise have on and thus a topic of conversation on those shows will be \"Why won't you use Skype or Hangout?\" I suspect most of the reasons will be free software focused, but they may also be privacy focused (not that they are unrelated).\n

The best descrition I can give this beer is it tastes just like that smell, even down to the dryness. Neither cloyingly sweet or leaving you wondering who mixed the chocolate syrup into you beer, just a sublte taste of dry cocoa. This lager pours dark with very little head. This beer (my favorite it this group) is only available in the Explorer pack, and it's ABV and ingredients are not featured on leinie.com.\n

Straw color, very clear, moderate head that disapears w/o lacing. Sublte flavor, a hit of hops and just slightly more than a pinch of pepper. 5.5 ABV Malts: Pale malts Hops: Five All-American hops including Simcoe and Citra \n

                                                            \nCranberry Ginger Shandy - [From Wikipedia, Shandy is beer mixed with a soft drink, carbonated lemonade, ginger beer, ginger ale, or apple juice or orange juice.] Pours cloudy yellow amber, moderate head that disapears w/o lacing. Leinenkugel managed to resist the urge to color it red. Not as syrupy as Shock Top\\'s Cranberry Belgian Ale, but unlike many fruit adjunct brews, neither is the flavor so subtle you have to go searching for it. I like to use ginger in cooking, and I can also detect the taste of that sweet spice in this weiss beer as well. 4.2% ABV \nMalts: Pale and Wheat Hops: Cluster Other: Natural cranberry and ginger flavors\n

Vanilla flavor is perhaps more subtle than Breckenridge's Vanilla Porter, but there will be know doubt you are enjoying a beer flavored by vanilla and roasted malts, with a hint of chocolate to keep it from being too sweet. 6.0 ABV \nMalts: Two- and six- row Pale Malt, Caramel 60, Carapils, Special B, Dark Chocolate and Roasted Barley Hops: Cluster & Willamette Other: Real vanilla\n

                                                            \n

                                                            \nBONUS ROUND -Leinenkugels Orange Shandy - Wheat beer, likely exactly the same one that's in the Cranberry Ginger Shandy, but in this case the tart/sweet orange juice taste dosn't completely obscure the flavor of the beer. I like them both, but I think I would grab the orange shandy on a hot day. 4.2% ABV \nMalts: Pale and Wheat Hops: Cluster Other: Natural orange flavor\n

                                                            \nHi this is Rho`n and welcome to my first submission to Hacker Public Radio. I have been working on an application using the Python programming language with the Enlightenment Foundation Libraries (EFL) libraries for the GUI interface. After acquiring a new laptop and installing a fresh copy of Ubuntu on it, I decided to set up the build environment I needed to be able to work on my project. I have been building from source the EFL libraries along with the Python-EFL wrapper libraries. For the last couple machines on which I have built the software, I would use the standard configure, make, and make install procedure. This time around I decided to create a debian package to use for installing the libraries. It had been a few years since I had created a .deb, so I googled for some tutorials, and found mention of the checkinstall program. After reading a couple blog posts about it I decided to try it out. checkinstall is run instead of \"make install\" , and will create a .deb file, and then install the newly created package.\n

                                                            \n\n

                                                            cut and tr commands

                                                            \n\n

                                                            \nTo help speed up the configure process, I had previously created a file from my other builds that is a grep of my history for all the various \"apt get install\" commands of the libraries the EFL software needs to compile. Since my current operating system was a freshly installed distribution of Ubuntu, I needed to install the build-essential package first. After looking through my install file, and I decided to create a single apt-get install line with all the packages listed, instead of running each of the installs seperately. I knew I could grep the file, and then pass that to awk or sed, but my skill with either isn't that great. I did a little searching to see what other tools were out there and found the cut command and the tr command. Cut lets you print part of a line. You can extract set a field delimeter with the -d option and then list a range of fields to be printed with the -f option. The tr command can replace a character. I used this to replace the new line character that was printed by the cut command to generate a single line of packages which I piped to a file. A quick edit of the file to add \"sudo apt-get install\" at the beginning, add execute permissions to the file, and now I have a nice, easy way to install all the needed libraries.\n

                                                            \n\n\n\n

                                                            apt-file and checkinstall

                                                            \n\n

                                                            \nAt least that was the idea. After installing the libraries, and running configure, I still received errors that libraries were missing. The machines from which my list of libraries was generated, had all been used for various development purposes, so some needed libraries were already installed on them, and so their installation had passed out of my history. Besides echoing to standard out the file configure can't find, it also creates a log file: config.log. Between the two it is relatively easy to figure out what library is needed. Often the libraries needed included their name in the .deb which has to be installed, and finding them is easy with an apt-cache search and grep of the library name. The hardest ones to find were often the X11 based references. In this case, I needed the scrnsaver.h header file. After googling, I found a reference to the needed package (libxss-dev) on Stack Exchange. The answer also showed how to use the apt-file command to determine in which package a file is included. I wish I had run into this before, there a few times where it took a number of searches on the internet to figure out which package I needed to install, and \"apt-file find\" would have saved time and frustration. A very handy tool for anyone developing on a debian based distribution. As it turns out, that was the last dependency that needed resolved. After a successful configure, and successful compile using the make command, I was ready to try out checkinstall. Running sudo checkinstall, brings up a series of questions about your package, helping you fill out the needed .deb meta-data. I filled out my name and email, name for the package, short description of the package, and let everything else go to the suggested defaults. After, that hit enter and checkinstall will create a debian package and install it for you. If you run \"apt-cache search <name of package>\" you will see it listed, and \"apt-cache show <name of package>\" will give you the details you created for the package. There are warnings on the Ubuntu wiki not to use this method for packages to be included in an archive or in a ppa. It does work great for a local install, and would use it to install on machines on my local network.\n

                                                            \n\n\n\n

                                                            conclusion

                                                            \n\n

                                                            \nAfter a short side trip into development setup, I'm back writing my application on my new laptop. While I am a big fan of binary packages, Debian being the first GNU/Linux distribution I ever used, sometimes you need to dive in and compile software from source. For me running configure, make, make install has been the easiest way to do this, and these days it usually isn't too difficult to get even moderately complex applications and libraries to build. The most tedious part can be resolving all the dependencies. Now, with apt-file in my tool belt, it will be even faster and easier. I will also be using checkinstall for future compiles. I do like being able to use package management tools to install, and un-install software.\n

                                                            \n

                                                            \nI hope others find these tools useful. I have posted links in the show notes to the pages about cut, tr, apt-file and checkinstall that led me to these tools. If you've made it this far, thanks for listening to my first post to HPR.

So let those episode ideas flow from your brain, into your favorite recording device, and up to the HPR server. Let's keep HPR active, vibrant, and a part of our lives for years to come. \n

                                                            \nUnrelated tech stuff: \nRecently, Knightwise showed me a link to use a Raspberry Pi as a streaming music box, much like a Sonos player https://www.woutervanwijk.nl/pimusicbox/ . I looked at the enclosures people had come up with and saw transistor radios from the 40s and 50s which were true works of art, but don't provide a great selection of controls. It was then I remembered seeing a 1950's juke box wallbox control ( https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR2.TRC1.A0.H0.Xjuke+box+wallbox&_nkw=juke+box+wallbox&_sacat=0 ) in a local \"antique\" shop. I'm never sure when addressing our European friends what parts of the American experience they are familiar with, but in the 40s to the 70s, in just about every American diner with a jukebox, at every booth there would be a remote console with a coin slot. Usually, you would have card tiles that could be rotated by a knob or by tabs, and each song would have a code made up of a letter and a number. Dropping in the required currency and making a selection would cause the song to be played on the jukebox (and sometimes on a set of stereo speakers in the wall unit). As you may see from the eBay link in the shownotes, wall boxes progressed from just a dozen titles in the 40s to far more complex systems, some with digital read out in the 80s. Most were marvels of late art deco design.\n

                                                            \n

                                                            \nMy parents were far to frugal to let me drop coins into one of these pioneering marvels of analog networking, but thanks to a couple modders who have tied their panels into a Raspberry Pi, I can give you a general overview of how these units communicated with the central jukebox via primitive serial protocols. First off, if you have the expectation of following in Phil Lavin's or Stephin Devlin's footsteps, be prepared to pay more for a wallbox certified to be ready to connect and work with the same brand's jukebox (while all wallboxes seemed to communicate by serial pulse, each company employed a different scheme). Wallboxes of all conditions seem to start around $50 on eBay, but can go into the thousands. As I said, all of the wallboxes are marvels of art deco design if they have no other purpose than to occupy your space and become a conversation piece. Right now on eBay, there is an example of a wallbox converted into a waitorless ordering system (this looks like it is from the 70s, only now do we have this functionallity with iPads at every table). In other words, where once was \"Stairway to Heaven\", now there was \"Steak and Eggs: $4.95\". The add on plaque covering the face of the unit identified the system as T.O.B.Y., for Totally Order By Yourself. I could find nothing on the tech on Google, but I really hope it was successful, because it truly would have been a master hack.\n

                                                            \n

                                                            \nFirst step. most wallboxes were powered from the jukebox, you can't just plug them into 120v alternating current, you will likely need a 25 or 30v adapter (research your model). If everything works, you should be able to drop your quarter, punch a letter number combo (which will stay down), then a motor will whir and you selected keys will punch back out. What happens in the background, the motor will cause an energized arm to sweep in a circle, making a circuit with electrodes in it's path. They keys selected determine how many pulses go down the output line, like a finger dialing a rotary phone.\n

                                                            \n

                                                            \nEach manufacturer used a different code. In the case of Steve Devlin's Rowe Ami, there would be an initial set of pulses for the number, a pause, then a more complex set for characters A-V (earlier wallboxes had 10 letters and 0-9 to create 100 selections, later boxes had as many as 200). Phil Lavin's Seeburg uses pulses corresponding to two base 20 digits, both protocols were discovered through trial and error. Each gentleman uses a different method to protect his Pi from overvolt. Devlin uses a 3.5v voltage regulator, which also makes the pulses appear more \"square\", Lavin uses an optical relay to electrically separate the Pi from Seeburg console entirely.\n

                                                            \n

                                                            \nBoth Lavin and Devlin use there wallboxes to control Sonos streaming players. My idea is more flexible, I'd like the Pi to be able to launch either streaming podcasts, or play the last ep of a selection of podcasts, or launch various home automation processes. I didn't think this talk warranted it's own podcast yet because it is clearly an unfinished idea, but I thought this application of old tech was too cool to wait until I was actually motivated to do something with it. If I get a wallbox, I might be inclined instead to connect each button to a momentary switch and wire each in turn to one of the Pi's 40 I/O pins for an even more flexible instruction set.\n

The twelve pack contains four varieties of beer, two are established Boulevard offerings, and the other two are bottled with non gloss \"generic\" labels that appear to have been hand typed. In other words, we are to believe we have been sold two prototype beers for our approval.\n

                                                            \n80 Acre \"Hoppy\" Wheat Beer (the quotes are mine). The graphics consist of an old Farmall tractor towing a pickup trailer carrying a gigantic hops bud. From this presentation, one would expect an oppressivly hoppy beer, fortunately for the hop timid this is a rather satisfying abulation that only registers 20 IBUs. I detect a distinct citrus taste, so I suspect Citra or related hops but Boulevard is keeping the exact specs closer to the vest than some other brewers. The brewers escription of the beer may be found here (link in the shownotes) https://www.boulevard.com/BoulevardBeers/80-acre-hoppy-wheat-beer/ Pours corn silk yellow with lots of head but not a lot of lacing. Damp wheat aroma.\n

Pours opaque dark brown with a very small lite brown head that disappears. Milk chocolate aroma. Thin mouth feel, choclately after taste that lasts more than a flavor washing over your tongue (i.e., you drink it, then you taste the chocolaty/coffee like essence). For locally brewed Oatmeal Stouts, I'd give the nod to Free State in Lawrence KS, but I wouldn't turn down the brew from K.C. if they decide to produce it. As it is not yet an \"official\", they don't document this beer on the Boulevard web page.\n

Pours the color of cloudy golden wheat straw, lots of persistent head that leaves little lacing. Slight biscuity aroma. Distinctly more citrusy than the 80 Acre. Not much malt and just a little hops bitterness. Despite the name, you can safely drink this beer to th bottom without winding up with a mouthful of particulates.\n

                                                            \n

                                                            \nMid Coast IPA: The last \"experimental\" beer. At 104 IBUs, this is where all the hops you expected from 80 Acre went. Pours wheat straw golden, thick white head that leaves little lacing, with a hoppy aroma. Even at 104 IBU, its has a slight sweet taste and doesn't seem to be one of those \"my hops can beat up your hops beers\". The label states: \"The hoppiest thing we have ever brewed. Pretty nervy for a bunch of midwesterners\". It's a great complement to the baked ham and spicey glaze I'm having for dinner (link in the show notes, even though I had to improvise somewhat).\nhttps://www.tasteofhome.com/recipes/apple-cider-glazed-ham\n

I like to rotate my wallpaper pictures every so often, so I want to have a collection of images. To this end I download the APOD on my server every day and make the images available through an NFS-mounted volume.

                                                            In 2012 I wrote a Perl script to perform the download, using a fairly primitive HTML parsing method. This script has been improved over the intervening years and now uses the Perl module HTML::TreeBuilder which I believe is much better at parsing HTML.

I use this to annotate the downloaded image with the title parsed from the HTML so I know what it is.

I chose to omit it because the installation of this suite and the related Perl module can be difficult. Also, I do not feel that the annotation always works as well as it could, and I have not yet found the time to correct this shortcoming.

This follows the object model, which is a lot like those Russian dolls inside of each other. The File for your spreadsheet is an object, and it contains individual Sheets which are objects. Each Sheet contains Cells which are objects. And each Cell contains various Characters which are objects, which can be used to represent numbers, formulas, addresses, labels, etc. Objects exhibit two features we always want to keep in mind. First, objects have properties that are particular to the kind of object. The properties of a file might include who the author is, where the file resides on the system, any access restrictions (like making the file password-protected), and so on. \n

We are now looking to expand on that by creating the resources needed by other communities to come together and be able to build on the CentOS Linux platform. And today we start the process by delivering a clear governance model, increased transparency and access. In the coming weeks we aim to publish our own roadmap that includes variants of the core CentOS Linux.

Free software, copyright alternatives and (cyber)feminism are important threads running through the activities of Constant. Constant organizes workshops, print-parties, walks and \"Verbindingen/Jonctions\"-meetings on a regular basis for a public that's into experiments, discussions and all kinds of exchanges.

                                                            A Libre Graphics Magazine is long overdue. In a market dominated by magazines devoted to design discourse built around proprietary tools and the latest computer graphics tricks and techniques, users of Libre Graphics software are underserved and unrecognized. We know that these users exist, both professionally and as hobbyists. We know this because we are they. We are graphic designers, media artists, photographers and web designers. We use Libre Graphics software, quietly and without regard. Our peers, used to proprietary alternatives, question our choice of tools. Our work, when executed well, is indistinguishable from work produced by more traditional means. Thus, our choices are invisible, unless we make an issue of them.

Its main focus is to integrate existing solutions for individual parts of the scanning workflow into a cohesive package that is intuitive to use and easy to extend. At its core, it handles the communication with the imaging devices, the post-processing of the captured material and its assembly into output formats like PDF or ePub. On top of this base layer, we have built a variety of interfaces that should fit into most use cases: A full-fledged and mobile-friendly web interface that can be served from even the most low-powered devices (like a Raspberry Pi), a graphical wizard for classical desktop users and a bare-bones command-line interface for purists.\n

Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture. The main goal of the ReactOS® project is to provide an operating system which is binary compatible with Windows. This will allow your Windows® applications and drivers to run as they would on your Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows® would find using ReactOS straightforward. The ultimate goal of ReactOS® is to allow you to use it as alternative to Windows® without the need to change software you are used to.\n

                                                            \n

                                                            I wrote a bash script to connect to various different windows servers from my GNU/Linux desktops. I had a few different requirements:

                                                            \n
                                                              \n
                                                            • I should be able to call it based on hostname.
                                                              • \n
                                                            • All windows should be 90% smaller than my screen.
                                                              • \n
                                                            • It should map my keyboard.
                                                              • \n
                                                            • It should map my local disk.
                                                              • \n
                                                            • It should quickly timeout if the port is not available.
                                                              • \n
                                                            \n

                                                            You can get the full script here, but let’s walk through it:

                                                            \n

                                                            The first line calls bash and then gets the server name from the symlink that is calling the script. The port is set as “3389”, but you can change that if you like.\n

                                                            \n
                                                            \n#!/bin/bash\nSERVER=`basename $0`\nPORT=\"3389\"\n
                                                            \n

                                                            The next few lines finds the smallest vertical and horizontal sizes, even if you are running multiple screens. Then it calculates 90% of that to use as the size.

                                                            \n
                                                            \nh=$(echo \"scale=0;(($(xrandr | grep '*+' | sed 's/x/ /g' | awk '{print $1}' | sort -n | head -1 )/100)*90)\" | bc)\nv=$(echo \"scale=0;(($(xrandr | grep '*+' | sed 's/x/ /g' | awk '{print $2}' | sort -n | head -1 )/100)*90)\" | bc)\nSIZE=${h}x${v}\n
                                                            \n

                                                            Next we set the default username and password. I have it ask me for my password but I put it in here as an example.

                                                            \n
                                                            \nPASSWORD='defaultpassword'\nUSERNAME='administrator'\nWORKGROUP='workgroup'\n
                                                            \n

                                                            In some cases the credentials may be different, so I have a case statement that will cycle through the servers and apply the differences. Depending on your naming schemes you may be able to use regular expressions here to filter out groups of servers.

                                                            \n
                                                            \ncase \"${SERVER}\" in\n  *server*) echo \"Server ${SERVER}\"\n    PASSWORD='work_password'\n    USERNAME='administrator'\n    WORKGROUP='WORKGROUP'\n    ;;\n \n  *colo*) echo \"Server ${SERVER}\"\n    PASSWORD='colo_server_password'\n    USERNAME='administrator'\n    WORKGROUP='COLODOMAIN'\n    ;;\n     \n  some_server ) echo \"Server ${SERVER}\"\n    PASSWORD='some_server_password'\n    USERNAME='some_server_password'\n    ;;\n  *) echo \"No match for ${SERVER}, using defaults\"\n    ;;\nesac\n
                                                            \n

                                                            Next we use an inbuilt bash command to see if a remote port is open and timeout after one second.

                                                            \n
                                                            \ntimeout 1 bash -c \"echo >/dev/tcp/${SERVER}/${PORT}\"\n
                                                            \n

                                                            I used to connect to rdp using the program rdesktop, but it is now of limited value due to the fact that there are many open bugs that are not getting fixed. Bugs such as Bug 1075697 - rdesktop cannot connect to systems using RDP version 6 or newer and Bug 1002978 - Failed to negotiate protocol, retrying with plain RDP . I then switch to using xfreerdp. This is the client that is behind remmina.

                                                            \n\n

                                                            You can use xfreerdp /kbd-list to get a list of the available keyboard layouts.

                                                            \n
                                                            \nif [ $? -eq 0 ]; then\n  echo \"${SERVER}:${PORT} is open\"\n  xfreerdp /v:${SERVER} /size:${SIZE} /kbd-type:0x00000409 /t:${SERVER} /d:${WORKGROUP} /u:${USERNAME} /p:${PASSWORD} /a:drive,pc,/ /cert-ignore &\nelse\n  echo \"${SERVER}:${PORT} is closed\"\nfi\n
                                                            \n\n

                                                            Next you will need to be sure that your host names are available, either in dns or in your /etc/hosts/ file. For example:

                                                            \n
                                                            10.1.0.1 server1\n10.1.0.2 server2\n10.1.0.3 server3\n10.2.0.1 coloserver1\n10.2.0.2 coloserver2\n10.2.0.3 coloserver3\n192.168.1.1 some_server\n
                                                            \n

                                                            Edit the script to your liking and then put it into your a directory in your path, possibly /usr/local/bash or ~/bin/. You can then make symbolic links to the servers to the bash script, also in a directory in your path, using the command:

                                                            \n
                                                            ln -s /usr/local/bash/rdp.bash ~/bin/some_server\nchmod +x ~/bin/some_server\n
                                                            \n

                                                            Which links the global rdp.bash script to your personal symlink, and makes it executable.

                                                            \n

                                                            All that you need to do then is type the name of the server and a rdp screen should pop up.

                                                            \n

                                                            In our example:

                                                            \n
                                                            $ some_server\n

                                                            \n

                                                            \nI was then asked to give the same presentation at the Portsmouth LUG.\n

                                                            Introduction to Vim

                                                            \n

                                                            This is the start of the Vim Hints series.

                                                            \n

                                                            As a Linux user there are many editors available to you. Which one you want to use depends on your needs and the amount of time you want to dedicate to learning how to use it.

                                                            \n

                                                            One of the editors from the early days of Unix is vi, written in 1976. Contemporary with it is Emacs, also originating in 1976. However, it seemed to become the norm (in my experience anyway) that vi rather than Emacs was provided as standard with versions of Unix, and this has often continued into Linux.

                                                            \n

                                                            I originally started using Unix around 1988 and found vi available to me. I learnt how to use it in a rudimentary way since I knew I'd find it on any Unix systems I came across.

                                                            \n

                                                            Many derivatives and clones of vi have been created. The one which has become the most popular and available is Vim, the name of which is an acronym for Vi IMproved, created in 1991 by Bram Moolenaar. This is what I use, and I have not wanted to learn another editor since adopting it, even though I have experimented with several. This is the editor we will be looking at in this series.

                                                            \n

                                                            What's the series about?

                                                            \n

                                                            The thinking behind this series is:

                                                            \n
                                                              \n
                                                            • You may already be using Vim; there are features you may not be aware of that can be revealed here
                                                              • \n
                                                            • You may be using a different, simpler editor; you might want to use Vim and gain from its advanced features
                                                              • \n
                                                            \n

                                                            Of course, you may prefer to learn Emacs instead. That's fine; you should choose the tool that best suits your needs. Both Emacs and Vim have quite steep learning curves, but the broad range of capabilities you gain from knowing either is considerable.

                                                            \n

                                                            I am not an expert in Vim. In fact I am continuing to learn new Vim features on a regular basis. However, I have been using it for many years and would like to share some of what I have learnt.

                                                            \n

                                                            Why use Vim?

                                                            \n

                                                            With simpler editors you can move about a file, add, remove and change text and save the results. The editor might have syntax highlighting and some degree of knowledge of the programming language you are typing. You might have spell checking as well.

                                                            \n

                                                            With Vim and other more advanced editors you have all of this and a lot more. You can perform global changes throughout a file, process many files at once, add plugins to the editor to change its behaviour, and so on. Also, there is a language behind the scenes which can be used to build extensions.

                                                            \n

                                                            Using Vim

                                                            \n

                                                            Usually, typing the command vi at the command line actually invokes vim. Vim runs in vi-compatible mode by default, which results in Vim enhancements being unavailable.

                                                            \n

                                                            Vim uses a configuration file, which is called .vimrc on Linux. (Vim will also run on Windows, OSX and other operating systems but we will not be covering these implementations in this series.) Vim also has a GUI interface invoked by the command gvim, and it has its own configuration file .gvimrc.

                                                            \n

                                                            I you don't have a .vimrc create one with touch ~/.vimrc before you start. This will stop Vim running in vi-compatible mode. We will look at what the .vimrc can be used to do later.

                                                            \n

                                                            You can start Vim on its own without pointing at a file, but normally you use it to edit a file, which need not already exist. So, to create a new file called testfile invoke Vim with the command: vim testfile

                                                            \n

                                                            Once running, Vim shows the contents of the file. All the lines on the screen where there is no content are marked with a tilde "~" character. If you are creating a file the first line on the screen will be blank, and last line will contain the name of the file followed by "[New File]" and some other details which we will examine later:

                                                            \n
                                                            "testfile" [New File]       0,0-1         All
                                                            \n

                                                            All the rest of the lines will contain a tilde.

                                                            \n

                                                            Vim is a modal editor. The mode you usually start in is normal mode where you can move around the lines of the file and perform actions, but nothing you type is actually written to the file. In fact, the keys you type are actually editing commands. This is one of the features of Vim that causes problems for new users.

                                                            \n

                                                            Since this is a new file there is not much you can do other than enter text, and to do this you need to switch to insert mode. Do this by pressing the i key. The message -- INSERT -- will appear on the bottom line of the screen. Now type some text, pressing the Enter key at the end of each line.

                                                            \n

                                                            You might notice that in insert mode you can press the arrow keys and move back to text you have already typed. This is a Vim feature and was not available in the original vi editor.

                                                            \n

                                                            When you have finished entering text, press the Esc key to exit from insert mode. Now you can move around in normal mode, but remember that the keys you press are now commands not data to be entered into the file.

                                                            \n

                                                            To move around in normal mode use the arrow keys or the home row keyboard keys: k to move up, j to move down, h to move left and l to move right.

                                                            \n

                                                            This brings us to the last mode we'll look at: command mode. To enter this mode press the : (colon) key in normal mode. This moves the cursor to the last line of the screen, which starts with the colon you just typed. Here you can enter another class of commands. This time, we'll just look at how you can save the file and exit Vim.

                                                            \n

                                                            Saving the file is achieved with the w command, and to exit from Vim the q command is used. These can be typed together, so :wq writes the file and exits.

                                                            \n

                                                            If you were to use :q on its own, having entered data into Vim, this would not work. Vim prevents you from throwing away your work this way. If you really meant to quit without saving then the q must be followed by an exclamation mark ("!"). So :q! lets you exit Vim without saving.

                                                            \n

If you are already familiar with Styles from Writer, think of Cell Styles as the equivalent of Writers Paragraph Styles. Just as a single Writer document can have a variety of Paragraph Styles applied to different paragraphs (e.g. Headings, Lists, Paragraphs), a single spreadsheet can have multiple Cell Styles. And the same arguments for using Styles also apply. If you have consistently used Cell Styles in your spreadsheet, you can update the appearance easily just by changing the Style instead of needing to go through the file looking for every cell that needs to be adjusted. And by using Styles you can apply a large number of formatting choices to many cells with just a few mouse clicks. So it really does pay to learn how to use Cell Styles.\n

                                                            Tree is a recursive directory listing program that produces a depth indented listing of files. Color is supported ala dircolors if the\nLS_COLORS environment variable is set, output is to a tty, and the -C flag is used. With no arguments, tree lists the files in the current\ndirectory. When directory arguments are given, tree lists all the files and/or directories found in the given directories each in turn. Upon completion\nof listing all files/directories found, tree returns the total number of files and/or directories listed.\n

                                                            By default, when a symbolic link is encountered, the path that the symbolic link refers to is printed after the name of the link in the format:\n\n

                                                            name -> real-path\n

                                                            If the '-l' option is given and the symbolic link refers to an actual directory, then tree will follow the path of the symbolic link as if it\nwere a real directory.\n

                                                            \nLast time we looked at some basics about how TLS and SSL work, and saw that this is basically an application of the same technology used to encrypt e-mails. But we also noted that there are some problems with this approach. We need to recognize that in security there is never a permanent solution, and that vulnerabilities are constantly being discovered, and ideally then being fixed. Some of these may involve highly technical issues about cryptographic methods, but I think the largest category of issues is about the processes around the use of certificates.\nFor more go to https://www.zwilnik.com/?page_id=686\n

                                                            \n

                                                            In this episode I want to look at how to keep your work secure with Vim. Next episode we will look at how to create and edit files.

                                                            \n

                                                            Avoiding data loss with a backup

                                                            \n

                                                            The best place to start is with the configuration file which we met last episode. As we saw, this is usually $HOME/.vimrc. However, it can also be $HOME/.vim/vimrc, which is actually recommended since it keeps all Vim files in the same place. I use the former, since that's the way I have always done it.

                                                            \n

                                                            Let's add some options to this file. Configuration options consist of command mode commands. Actually, to be precise about it, any Vim Script expression may be written there.

                                                            \n

                                                            First it's a good idea to ensure that Vim runs with all of its standard features enabled. The option for this is called compatible (meaning compatible with Vi), which we need to turn off. This is done with the option:

                                                            \n
                                                            set nocompatible
                                                            \n

                                                            Next, it's highly advisable to make Vim generate a backup file whenever it opens a file for editing. The backup file has the same name as the original file with a tilde appended. The configuration command is:

                                                            \n
                                                            set backup
                                                            \n

                                                            The backup file is a copy of the file which existed before editing started.

                                                            \n

                                                            By default the backup file is saved in the same directory as the file being edited. If this is a problem (and to me this is not), then it is possible to tell Vim to save backups in a fixed place. This is done with the command set backupdir= followed by a list of directories. For example:

                                                            \n
                                                            set backupdir=~/.backup,.,/tmp
                                                            \n

                                                            If you were to add this to your configuration file, Vim would save backups in a top-level directory ~/.backup (which must already exist), then if this fails it will save in the current directory, falling back to /tmp if all else fails. Whether you do this is up to you. I would suggest you do not, at least not until you are more experienced with Vim.

                                                            \n

                                                            Undoing and redoing changes

                                                            \n

                                                            Vim can undo changes you make to a file. This is useful if a change was the wrong change or in the wrong place. It can also redo the undone change.

                                                            \n

                                                            The u command in normal mode undoes the last change. The redo function is invoked by pressing the Ctrl key while pressing r. This key sequence is normally represented as CTRL-R.

                                                            \n

                                                            Vim keeps a record of the changes, so successive u commands undo successive changes back in time. Conversely, CTRL-R redoes the undone changes forward in time.

                                                            \n

                                                            Normally the change history is lost when Vim exits, but two configuration options can be used to save it. The undofile option ensures change history is written to a file and undodir shows the (pre-existing) directory which is to hold these files.

                                                            \n
                                                            set undodir=~/.vim/undodir\nset undofile
                                                            \n

                                                            It can be a little surprising if you press u in a file you have just opened in Vim to find that it undoes something you changed last time you edited it! However, on the whole I think this is a great feature.

                                                            \n

                                                            File recovery

                                                            \n

                                                            The Swap File

                                                            \n

                                                            By default Vim uses a recovery mechanism where it generates a swap file. Under Unix and Linux this file has a name built from the name of the file being edited with a dot prepended (making it a hidden file) and with the extension ".swp". So, if you were editing the file testfile the swap file would be a file called .testfile.swp in the same directory.

                                                            \n

                                                            It is possible to make Vim write the swap file elsewhere, such as on another partition. You can also turn this recovery capability off. It is probably advisable to use the default settings while you are learning Vim.

                                                            \n

                                                            The swap file is updated after typing 200 characters or when you have not typed anything for four seconds. The swap file is deleted as soon as Vim stops editing the file.

                                                            \n

                                                            Recovery

                                                            \n
                                                            Case 1: there are changes in the swap file
                                                            \n

                                                            If something bad happens during an editing session, such as the loss of power, the swap file will remain after the event. If you know that you need to recover your edit session then you can simply type the following in the directory where the file you were editing exists:

                                                            \n
                                                            vim -r filename
                                                            \n

                                                            You will see a message such as the following:

                                                            \n
                                                            \n
                                                            Using swap file ".testfile3.swp"\nOriginal file "~/testfile3"\nRecovery completed. You should check if everything is OK.\n(You might want to write out this file under another name\nand run diff with the original file to check for changes)\nYou may want to delete the .swp file now.\n\nPress ENTER or type command to continue
                                                            \n
                                                            \n

                                                            See the explanation on the Vim wiki.

                                                            Alternatively, when you try to edit a file you were editing at the time of the failure Vim will detect the presence of a swap file and alert you with a message such as:

                                                            \n

                                                            \n

                                                            Vim here is indicating that there are unsaved changes that can be recovered. It is also warning that if someone is editing the same file (such as you in another window) this might account for the presence of the swap file.

                                                            \n

                                                            Assuming it's appropriate, you can recover the changes and continue editing by pressing r at the above prompt. You will see messages such as the ones above relating to the vim -r filename example.

                                                            \n

                                                            Be aware that if you continue editing the original swap file will continue to exist and you will get the same message again next time you edit the file. Vim will create a new swap file (called /home/hprdemo/.testfile2.swo in this case) to protect the new editing session.

                                                            \n

                                                            This situation can be a little confusing if you have not encountered it before. There are a number of ways you can resolve this:

                                                            \n
                                                              \n

                                                            1. You can save the recovered file and exit Vim (type :wq). You can then edit the same file all over again. You will see almost the same message as before, but you can now delete the swap file by pressing d. The message you see the second time round will contain the additional warning that the file you are editing is newer than the swap file - that is because you just saved a new copy of it!

                                                              2. \n

                                                            2. You can save the file and exit Vim as above, but then explicitly delete the swap file. In the example you would do this by typing: rm .testfile2.swp

                                                              3. \n

                                                            3. As before you can save the file but this time without exiting Vim (type :w). Then tell Vim to re-edit the current file with the command :e. You will then see the warning about there being a swap file, and you can type d to delete it.

                                                              4. \n
                                                            \n
                                                            Case 2: there are no changes in the swap file
                                                            \n

                                                            If, when you see the message about finding a swap file you see that there are no changes to recover you can just delete the swap file by pressing d. You can then continue with editing the file as normal.

                                                            \n

                                                            Don't Panic!

                                                            \n

                                                            This recovery process is complex because Vim is trying to ensure that you are protected against losing your changes.

                                                            \n

                                                            As it says in the Vim manual DON'T PANIC!

                                                            \nThe great thing about brew pubs is that they always trying new beers so the customer experience doesn't become as stale as a half finished can of Budweiser let out overnight. That means I can return to the same place and experience a whole new vista of flavors. Such was the case last Sunday, when a social affair brought me withing blocks of the River City Brewing Company in Wichita Kansas. I had the forethought to be my three growlers for refilling, and by the time the meeting was of it was time for a burger and a beer anyway. Lets talk about the meal first.\n

                                                            \n

                                                            \nHaving already tried their pizza and amazing Cuban sandwich on previous trips, this time a went for a burger. From the River City menu ( https://www.rivercitybrewingco.com/rcbmenu.pdf ) The Memphis Burger is topped with sweet pepper bacon, cheddar cheese, crispy onion strings and chipotle BBQ sauce. On top of all that, the hamburger was grilled to perfection, in my case that being exceedingly rare. (One of my Dads friends, every time he sees me eating a steak or a burger, always comments You know, I've seen a critter hurt worse that that and live). I was most impressed by the onion strings. These are not the French fried onion rings that you find atop your green beans on Thanksgiving, but rather the most delicate strings of onion imaginable, battered and fried. I found myself wishing Id thought to order extra BBQ sauce for my French fries, which were hearty and sprinkled with fresh ground black pepper. Id never thought of peppering my fries before, but be assured Ill do so in the future.\n

                                                            \n

                                                            \nTo accompany my burger, I selected the Breckenridge Bourbon Smoked Imperial Stout. It weighs in at 9.0%abv, so you get a smaller that average portion in an 11oz brandy snifter. While stouts are usually nearly as bitter as IPAs, I don't notice it as much when coupled with the beers bold flavor. Unlike IPAs, stouts tend to have enough malty richness to add balance. In the case of this beer, the barley is smoked over hazelnuts before fermentation, giving this beer its flavor and its name. I've want to try a smoked stout since I heard Tracy Hotlz speak of them back on the old Podbrewers show. I don't think Id want to be restricted to an exclusive diet of smoked beers, but this was a welcome change from the ordinary, and a great compliment to my beefy repast. Truly an excellent brew.\n

                                                            \n

                                                            \nNow, on to the contents of my three growlers. I wish I could give you first impressions, but come on, I just couldn't wait for you folks. It was hard enough to wait for the containers to chill overnight in the fridge.\n

                                                            \n

                                                            \nThe first beer is even more unique than the smoked stout. Donut Whole Love Affair #3 Pineapple Wit is made with actual pineapple donuts (from River Citys Facebook page https://www.facebook.com/RiverCityBreweryCo/photos/a.555320064516059.1073741826.194563133925089/796375363743860/?type=1 ). The first taste you encounter is tart pineapple on the tip of your tongue joined by powdered sugar as the beer washes towards the back of you mouth. The sugar taste tends to stay with you between sips, but the whole effect is subtle and wonderful, not fruit juicy like a shandy. The wheat beer hovers in the background, not enough to obscure the donut, but blending the pastry taste into the breadyness of the beer. I didn't know what to expect of this beer when I ordered it, but I am most pleased I did. 5.65abv 11 IBUs 16oz Weizen\n

                                                            \n

                                                            \nNext, we have Pryze Fyter Red Rye. By far, this is the smoothest and richest rye beer I've ever tasted. I'm a big fan of rye beers, but they tend to be a little more harsh than wheat beers, and are of course more bitter. Like rye whiskey, rye beer is an acquired taste for many people, and best suited for those with a palette that craves bold flavors. According to the menu, Carmel malts, a copious amount of rye. Spicy, floral, earthy, and ready to smack you in the kisser. 5.6%abv 55 IBUs 16oz Nonic\n

                                                            \n

                                                            \nFinally, we have the Buffeit Bourbon Baltic Porter. Of the two bourbon barrel aged porters on the menu, my barman described this slightly sweeter. While I've never been a fan of the woody tasting bourbons of Tennessee, barrel aging lends a roundness to beers, and compliments the roasted malts and the hops. This is the strongest of the beers I brought home, at 7.2%abv, 47IBUs, and would be served in a 13z Tulip glass.\n

                                                            \n

                                                            \nI made the mistake of not taking a beer menu home with me for documentation, as a list of currently available beers no longer appears on line. Chris Arnold took the time to scan a copy and send it to my e-mail. Thanks Chris. I don't think River City Brewing Company will mind me attaching the menu to my notes for you listeners to salivate over. There are two in particular I'm sorry to have missed, the Stinky Pete Plum Saison (they always seems to be out of the raisin and plum beers) and the Emerald City Stout (a man has only so many growlers).\n

Among the many interviews I want to do from Linux Fest next week, I'm also going to visit the Free State Brewery, only a couple blocks away. I called ahead, and they wont fill other pubs growlers (that's going to cost you some points Free State). On the upside, I'll have a couple new growlers to add to my collection.\n

                                                            \nIn July of 2010 I was given a laptop to repair by one of my friends, I couldn’t figure out what was wrong with it despite hours of trial and error so eventually I got so frustrated with it that I just set it aside and forgot about for a while. Meanwhile my friend got another laptop so he told me I could keep it.\n

                                                            I usually create my notes with Markdown and pandoc. As an experiment this time I have used a pandoc template which uses the same CSS that provides the style for the main HPR pages. I hope it makes these notes look better than the very bare HTML I have produced in the past.

Many persons find it intimidating for the absence of a\nmenu bar, a terse command set that is very much its own, and its \"modal\"\ndesign.\n

                                                            1. Use a .vimrc file.
                                                              2. \n
                                                            2. Train yourself to change modes.

                                                            3. Learn and use a few basic commands. These should be enough to get you\ngoing: x, dd, dw (to delete text); cw (change a work); yy (\"yank\" or copy a\nline); p and P (to paste text); u (undo); w (\"write\") or save text; q (quit vim).

                                                            4. Don't force yourself to move the cursor with the h-j-k-l keys if that doesn't feel natural.\nUse the arrow keys.
                                                              5. \n
                                                            5. Use vim to write stuff.

How the attacker gained access to the codes is not known, but it is thought that it may be linked to a breach that occurred at the end of March 2012 to the Credit card processor Global Payments. That attack exposed 1.5 million consumers financial data. These codes have been confirmed by security experts to be legitimate and in wide spread use even today. Despite this exposure been \"common knowledge\" among the security community, major banks and credit card companies have yet to issue any statement on the breach.\n

                                                            In February 2015 I created a script to add a section to the monthly Community News show notes. The added section summarises the discussions on the HPR mailing list over the previous month. My script processes the messages archived on the Gmane site and reports on the threads it finds there.

                                                            \n

                                                            In writing this script I noticed the number of times people made errors in replying to existing message threads and initiating new threads on the list. I thought it might be helpful if I explained some of the do's and don'ts of mailing list use to help avoid these errors.

                                                            \nHowdy folks, this is 5150 for Hacker Public Radio. What you are about to hear is a presentation titled \"How to Get Yourself on an Open Source Podcast\" that I delivered at Kansas Linux Fest on 22 March 2015. Since it was not recorded (I was told the SD card was full), and there has been interest expressed by my fellow podcasters, I thought it might be worth re-recording. I am afraid Mike Dupont is not satisfied with any of the video from KLF 2015, this may be the only talk from that event you get to hear. However, show notes are extensive, https://lanyrd.com/2015/klf15/schedule/ All I can tell you is, three out of the four audience members seemed to enjoy my presentation. I shall deliver the rest of this podcast as if you gentile listeners were my live audience.\n

                                                            \n

                                                            \nA. Howdy folks, my name is Don Grier. I'm an IT consultant and farmer from South Central Kansas. I am also a podcaster. You might recognize my voice from such podcasts as Hacker Public Radio, the Kernel Panic Oggcast, or Linux LUG Cast, where I use the handle, FiftyOneFifty.\n

                                                            \n

                                                            \nI. When fellow Hacker Public Radio host Mike Dupont told me KLF would be a reality, I struggled to find a topic that I knew well enough to give a talk about. It was almost in jest that I said I could talk about \"How to Get Yourself on an Open Source Podcast\". Actually, since that was as far as my proposal went, I was shocked and honored to find myself on the same roster with so many other speakers with impressive credentials and technical topics.\n

                                                            \n

                                                            \nII. This afternoon, I hope not only to chronicle my personal history with Linux and open source related podcasts, but to show you why I believe podcasting can be as an important part of giving back to the community as contributing code, or documentation, or cash. Linux podcasts bind the community by providing education, both as basic as Linux Reality or as specific as GNU World Order. Podcasts announce new innovations, and tell us of Free and Open Source software adoption and opposition in corporations and governments. Podcasts herald community events like this one, and provide a little humor at the end of a long day.\n

                                                            \n

                                                            \nB. Some of you may wonder why I'm using old school technology to organize my notes at a high tech conference. At this point, 5150 holds up several stapled sheets of paper in large print. The plain and simple truth is that I can't read my phone or tablet with my glasses on; and I'm already using bifocals. It just seems every time I get new glasses, the lower lenses work for about two weeks, then I have to take then off to see the phone. But this last time I figured I'd outsmart my the system and just order a single focus lenses. I was still congratulating myself on my thriftiness when I put my new glasses on, sat down at the computer, and realized I couldn't read the keyboard.\n

                                                            \n

                                                            \nC. Before I talk about my history as a podcaster, I think I should tell you my history with Linux.\n

                                                            \n

                                                            \nI. My first experience with Linux was with a boxed set of Mandrake 7.2 around 2002. I always maintain at least a second running system in the house, in case the primary machine coughs up a hairball. I'd always been a geek alternative OS's, and I wanted a tertiary machine on my network that wouldn't be affected by the propagation of Windows viruses. \n

                                                            \n

                                                            \na. There wasn't much flash to Linux apps in those days, I recall I was not impressed by whichever browser shipped with Mandrake. I don't recall what I knew about installing additional applications from repositories, but in any case I was still on dialup. \n

                                                            \n

                                                            \nb. The Pentium I that I installed Mandrake on had both a modem and an Ethernet card. The installer asked which one I used to reach the Internet, and only set up one of the two devices. This annoyed me as I'd planned to use the Linux box as a gateway to see if it would save a few CPU cycles on the P4 I used as a gaming machine back then. I really wouldn't have know where to go on the Internet for help, and I expect help would not be as forth coming 13 years ago.\n

                                                            \n

                                                            \nII. My next experience with Linux came around 2007. The school I consulted for had several Windows 98 machines not compatible with the software they wanted to run. Even though the machines were P4's, we determined the cost of XP plus memory upgrades could better be applied to new machines. As a result, I was able to bring several of the machines home. Over time, I boosted their memory with used sticks from eBay, and even the odd faster processor. As a noob, I installed Feisty Fawn on a system out in the machine shed, and spent a lot of that winter hacking on that box when I should have been overhauling tractors. Just as I was delving into NDIS wrappers, Gusty brought support for my Gigabyte wireless card, which combined with a double fork isolating power box, gave me reasonable certainty that the box out in the shed was safe from lightning storms. About six months later, I rescued up a refugee from a major meteorological event and set it up in my house running Mint. For the first time I didn't have to leave the house to get my Linux on.\n

                                                            \n

                                                            \nD. Just before I set up that first Linux box, we finally got broadband out to the farm, and I'd discovered podcasts. I figured there must be Linux podcasts to go along the general tech and computing podcasts I followed, as well as a fondly remembered weekly SciFi revue show that started out as a Sunday afternoon show on a Wichita radio station, was canceled twice, and re-emerged as a semi weekly podcast, only to disappear forever a couple months after I started listening again, but not before I download all the episodes I missed.\n

                                                            \n

                                                            \nI. In my initial search for Linux related content, all I came up with were four drunk off their ass Scots discussing the minutia of Ruby on Rails. While I liked the format, I lacked the commitment to become a Ruby programmer so I could understand the show.\n

                                                            \n

                                                            \nII. A few days later I came across \"The Techie Geek\". Russ Wenner mixed tutorials with reviews of new applications and upcoming events. Better yet, he introduced me to a world of other Linux podcasts. Through \"The Techie Geek\", I learned of the irreverent banter of the \"Linux Outlaws\", the subdued studiousness of what was then called \"The Bad Apples\", the contained chaos of the \"Linux Cranks\", the classroom like atmosphere of the \"Linux Basement\" during Chad's Drupal tutorial period, tech hints and movie reviews delivered at the speed of 75 miles per hour by Dave Yates of \"Lotta Linux Links\", the auditory dissonance of \"The Linux Link Tech Show\", and the constant daily variety of \"Hacker Public Radio\".\n

                                                            \n

                                                            \nE. In 2010, I made my first contribution to Hacker Public Radio. The great thing about HPR is that there is no vetting process, we only ask your audio be intelligible (not polished, not even good, we just have to be able to understand you) and that the topic be of interest to geeks. If you consider yourself a geek, any topic that interests you is welcome. There is no maximum or minimum runtime, just get the show uploaded on-time. While topics tend concern open source, this is not a requirement. I believe my second HPR concerned how to migrate Windows wireless connection profiles between systems. I'd spent a few hours figuring it out one day for a customer and I thought I should consolidate what I learned in one place. HPR provides a podcasting platform at no cost to the podcaster. It serves as both a venue for broadcasters without the resources to host their own site or without the time to commit to a regular schedule. It can also serve as an incubator for hosts trying to find their own audience. It's never been easier to become a podcaster with HPR. I would start with an e-mail introduction (as a courtesy) to admin@HackerPublicRadio.org. Next, record you audio. When you have a file ready to upload, select an open slot in the calendar page and follow the instructions, be prepared to paste in your shownotes. \n

                                                            \n

                                                            \nF. I also credit HPR for getting me my first invite to participate in my first podcast with multiple hosts. Once a month, Hacker Public Radio records a Community News podcast, recorded on the first Saturday afternoon after the end of the previous month (exact times and server details are published in the newsletter). All HPR hosts, and indeed listeners are invited to participate, it is just asked that you have listened to most the the past month's shows so you can participate in the discussion. \n

                                                            \n

                                                            \nI. Like most multi-host audio podcast's, HPR uses Mumble to record shows, including the annual New Year's Eve show, which has dozens of participants. There is a Mumble tutorial on LinuxLUGCast.com to help you get started.\n

                                                            \n

                                                            \nII. I started to take part in Hacker Public Radio's Community News a few months after recording my first podcast. I did it because I wanted to take a greater part in HPR, not because I considered it an audition, but it is a good way to show other people that you can politely and intelligently participate in a group discussion. (Actually, I have a tendency to wander off into tangents and unintentionally dominate the topic, something I struggle with to this day).\n

                                                            \n

                                                            \nIII. Another way to join in a round table discussion on HPR is to participate in the HPR Book Club. Once a month, we take an audio book that is freely available on the Internet and share our opinions. Recording schedules and the next book to be reviewed are available in the HPR newsletter.\n

                                                            \n

                                                            \nG. I believe sharing one or more Community News with Patrick Dailey (aka pokey) influenced him to invite me into the cast of Dev Random. The semi weekly Dev Random recorded of the Saturdays Kernel Panic didn't. While we sometimes accidentally talked about tech and open source, we always saved the most disturbing things we'd seen on the Internet in the previous two weeks for discussion on the show, things that could not be discussed on other podcasts. Despite rumors to the contrary, dev random is not dead, only resting, and shall one day rise again to shock and disgust new generations of listeners.\n

                                                            \n

                                                            \nH. Sometimes you just have to be in the right place at the right time. I won't insult the Kernel Panic Oggcast by calling it a sister show to Dev Random, it just recorded on opposite Saturdays and had some of the same cast members in common. Anyway, I'd been participating in the forum for a while, suggesting topics from FOSS stories I'd come across in social media during the week. I was idling in #oggcastplanet on Freenode when Peter Cross asked for people from the channel to participate in the show on a day only a couple of the regular cast showed up. Dev Random used the same Mumble server, so I used my existing credentials to take Peter up on his offer, and for better or worse I've been a KPO cast member ever since. \n

                                                            \n

                                                            \nI. While we are on the topic, having a presence on Freenode IRC chat is a great way to get your name or handle known in the podcasting world. Many podcasts have their own channel set up that listeners participate in during live streaming podcasts. Saying something helpful, (or more likely smart alecky) might get you mentioned on the show and make you familiar to the shows audience. I've seen several individuals move from regular forum or chat participants to the hosts of their own show or contributors to HPR. From my own experience, after spending several weeks as silent participants in Podbrewers, listening to the stream and commenting in the chat, RedDwarf and myself were invited to bring our own beers and join the cast. \n

                                                            \n

                                                            \nI. While many podcasts still have their own IRC channels, other than providing a conduit between the hosts, they are most active during live broadcasts. Between shows, many of the podcasters I listen to gravitate to hanging around in Freenode's #oggcastplanet , since podcasters typically have a chat client open during work and leisure hours. In fact, at KPO we use #oggcastplanet as our primary communications channel during live streaming. \n

                                                            \n

                                                            \nII. I still recall the day monsterb and Peter64 asked me about the origin of my handle, given it's similarity to their colleague, threethirty. I'd heard both on podcasts I followed, and I felt like I was talking to rock stars.\n

                                                            \n

                                                            \nIII. Now that I am a podcaster in my own right, with a presence in #oggcastplanet, I try to make a point to say hello when I see an unfamiliar handle in the channel. I expect the spambots consider me the nicest guy in IRC. \n

                                                            \n

                                                            \nIV. As it happens, IRC was also responsible for my involvement in the Linux LUG Cast. LLC was conceived after the re-imaginging and final demise of Steve McLaughlin's project, \"Linux Basix\". Kevin Wisher, chattr, and honkeymaggo wanted to do a show along the same lines while incorporating the spirit of the unrecorded online LUG that always preceded it on the mumble server. I was brought along by the simple expediency of never having closed the #LinuxBasix channel in my chat client. We have been going for a little more than a year and have attracted a following, but frankly we have not found the listener participation we were looking for. This was meant to be a true online Linux Users Group for people couldn't travel to a LUG. So far, it's usually been the same four of five guys talking about what Linux projects succeed, what failed, and what we we're going to try next. I've learned a lot in the past year, and I expect the listeners have as well, but we are always hoping to get more live participation. Rural areas like the midwest are our target audience. The details of the Mumble connection are posted at LinuxLUGCast.com, we always monitor the Freenode.org IRC channel #linuxlugcast while recording, and the Feedback link is posted on the website.\n

I'm currently working on gathering the fund to attend the Southern California Linux Expo aka SCALE. As many of you already know I have spent the last year struggling against esophageal cancer. I am nearing a point which I can start traveling and attending conferences again. My goal is to raise the funds so that in February of 2015 I can attend Scale. I am also working on a talk that I hope to give at SCALE. My sincerest thanks to the community that has been there for me during my recovery and to those that will help me in this endeavor. Should I raise more funds than needed to attend SCALE my goal will be to submit my talk to other conferences and to give my talk at those as well.\n

Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.\n

My dad has been on the SCALE leadership team for a long time, and he introduced me to programming. My favorite programming languages are HTML and Javascript with Enyo because I like creating websites and webOS apps. I also program in Shell and some Python, and like making short animations using Blender. I have recently made the world's first emulator for the WITCH, the first currently working fixed-point decimal computer. I recently earned my Technician Amateur Radio license and enjoy attending radio club meetings. Besides geeking, I like to swim, act, and do fun events with the Boy Scouts.\n

                                                            Save this complicated command as an environment variable—then the variable \"$KEYPRESS\" expands to this command.

                                                            With virtual keystrokes and CLI access to the clipboard, you're limited only by your imagination and scripting ability. Here are some examples of how I use them, both for the manipulation of text and for navigation. The words in bold-face are the voice commands I use to launch the written commands.

                                                            \n\n

                                                            Capitalize this. Copies selected text to the clipboard, pipes it through sed and back into the clipboard, then types fixed text back into my document:

                                                            \n\n
                                                            \nxdotool key Control+c && xclip -o \\
                                                            | sed 's/\\(.*\\)/\\L\\1/' \\
                                                            | sed -r 's/\\<./\\U&/g' \\
                                                            | xclip -i && $KEYPRESS "$(xclip -o)" 
                                                            \n
                                                            \n
                                                            \n\n

                                                            Go to grades. This example takes advantage of Firefox \"quick search.\" I start with a single quote to match the linked text \"grades\" and press the Return key (\\r) to follow the link:

                                                            \n\n
                                                            \n
                                                            $KEYPRESS "'grades\\r"
                                                            \n

                                                            First Inbox. From any location within Thunderbird I can run this command and it executes the keystrokes to take me to the first inbox and put focus on the first message:

                                                            \n\n

                                                            \n\n

                                                            single ex staff. Type out an entire Lilypond template into an empty text editor window:

                                                            I normally use blather voice commands to launch the scripts and keystroke commands, but I have a handful of frequently-used commands that I launch using keystroke combos configured in the Openbox config file (~/.config/openbox/rc.xml on my system). This block configures the super+n key combo to launch my examplelink.sh script.

                                                            In this episode I respond to one of the community-requested topics (\"Music Theory\") and try to explain what seventh chords are and why they are used. Below are some of the terms that I use in the course of the discussion.

                                                            \n\n
                                                              \n
                                                            • Interval: The distance between two pitches (sounded either consecutively or simultaneously)
                                                              • \n
                                                            • Consonance: Relatively stable sound between two or more pitches
                                                              • \n
                                                            • Dissonance: Relatively unstable sound between two or more pitches. Dissonance often needs a "resolution" to consonance
                                                              • \n
                                                            • Chord: three or more notes sounded together
                                                              • \n
                                                            • Chord progression: a succession of chords
                                                              • \n
                                                            • Triad: a chord with 3 pitches, the adjacent pitches separated by the interval of the 3rd.
                                                              • \n
                                                            • Seventh chord: a chord with 4 pitches, the adjacent pitches separated by the interval of the 3rd.
                                                              • \n
                                                            • Tonality: harmonic system that governs the use of major and minor keys
                                                              • \n
                                                            • Tonic: the central tone of a piece of music
                                                              • \n
                                                            • Mode: major or minor [e.g. Symphony no. 5 in C minor]
                                                              • \n
                                                            • Modulation: the process of changing keys within a piece of music
                                                              • \n
                                                            • Scale: Ascending or descending series of notes that define a key or tonality, with a specific arrangements of half-steps and whole-steps. Major and Minor scales are most common in Western music

                                                            DESCRIPTION
                                                            ranger is a console file manager with VI key bindings. It provides a minimalistic and nice curses interface with a view on the directory hierarchy. The secondary task of ranger is to figure out which program you want to use to open your files with.

                                                            \n

                                                            This manual mainly contains information on the usage of ranger. Refer to the README for install instructions and to doc/HACKING for development specific information. For configuration, see the files in ranger/config. They are usually installed to /etc/ranger/config and can be obtained with ranger's --copy-config option.

                                                            \n

                                                            Inside ranger, you can press 1? for a list of key bindings, 2? for a list of commands and 3? for a list of settings.

                                                            Overview

                                                            \n

                                                            I enjoy writing Bash scripts to solve various problems. In particular I have a number of scripts I use to manage the process of preparing a show for HPR, which I am developing at the moment.

                                                            \n

                                                            My more complex Bash scripts use a lot of functions to perform the various tasks, and, in the nature of things, some of these functions can be of use in other scripts and are shared between them.

                                                            \n

                                                            I thought I would share some of these functions with HPR listeners in the hopes that they might be useful. It would also be interesting to receive feedback on these functions and would be great if other Bash users contributed ideas of their own.

                                                            Extract pages 3–5 from file foobar.pdf:

                                                            \n\n

                                                            \n\n

                                                            Same thing but also grab the cover page:

                                                            \n\n
                                                            \npdftk foobar.pdf cat 1 3-5 output excerpt.pdf\n
                                                            \n\n

                                                            Combine multiple PDFs:

                                                            \n\n
                                                            \npdftk file1.pdf file2.pdf file3.pdf cat output combined.pdf\n
                                                            \n\n

                                                            Reassemble a 50-page document with all of the pages in reverse order (I once actually did this for my wife and she was very grateful—she had scanned an article at the library and it ended up with all of the pages in the wrong order from last to first. This command solved her problem in about one second.):

                                                            \n\n
                                                            \npdftk wrongorder.pdf cat 50-1 output rightorder.pdf\n
                                                            \n\n

                                                            Check the pdftk man page for all kinds of other manipulations you can do, including \"bursting\" a PDF into its component pages, rotating pages in any direction, applying password protection, etc.

                                                            \n\n

                                                            Embedding “Bookmarks” as a Table of Contents

                                                            \n\n

                                                            You can also use pdftk to embed a table of contents in a flat PDF file. This is incredibly useful, as it can make large, unwieldy files very easy to navigate. All you have to do is add some bookmark data in a fairly straightforward format as shown below. As a starting point you should that dump the current metadata content of the file with this command:

                                                            \n\n
                                                            \npdftk foobar.pdf dump_data_utf8\n
                                                            \n\n

                                                            Save the contents of this data dump in a text file and then add bookmark information just below the NumberOfPages value. Here is an excerpt from the huge anthology of public-domain scores I assembled for my music history class:

                                                            And here is the command to update the PDF with the table of contents embedded. This tells it to take the input file foobar.pdf and update its metadata using the file foobar.info (with utf8 encoding) and output the results as foobar_with_toc.pdf.

This beverage features subtle hoppy notes and a slightly smoky finish. Also, ~15% ABV, so I might have been a touch loopy the rest of the show

Very drinkable, but not mind blowing. I suspect this beer appeals to a wide audience. I've been on more of a \"specialty\" beer kick for a while, so this was almost disapointing.https://www.samueladams.com/craft-beers/summer-ale/

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with its default settings to minimize the silence between people speaking. When used with its default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember to save after every major transform, you will wonder how it ever got that reputation.

                                                            Hi everybody! This is John Kulp In Lafayette, Louisiana. I am going to do a rather strange episode today. What I'm doing is demonstrating the dictation software that I use on the office computer that I have here at work. If you listen to my previous episodes, then you have heard me speak of the blather speech recognition program that I use on my Linux desktop, but as you may also remember, blather is not a dictation tool. Blather is a tool where you have to set up commands that will run other commands. In other words, you have to configure everything from scratch. I do have some capabilities for dictation on my Linux desktop, but they involve using the Google Web speech API and a special dictation box that I have set up, and these are not at all good for longform dictation. For serious dictation, such as writing letters and memos and other longform text, you really need a proper dictation tool. These are available built into the operating systems of Windows and Mac OS 10, but I normally use the Dragon naturally speaking software instead. I have found that it is more accurate and more powerful than the built-in versions that you can get on either Windows or Mac. That doesn't mean you shouldn't try out the built-in speech recognition on Windows and Mac, you definitely should, because I think you would be very impressed with him. I know for sure that the version on Windows learns from your voice and from the corrections that you make to the text that you were spoken, and eventually becomes very powerful in recognizing your speech. The biggest problem that I had with the Windows speech recognition was that it was a huge memory hog and frequently brought my system to a grinding halt. This is not good. Blather never does that, but then again bladder cannot take dictation. The latest system that I use for dictation is on a fairly recent Mac Mini running the nuance Dragon Dictate software. This is a very powerful dictation program that learns from your speech patterns and you can also add words to the vocabulary so that it will get them right when it hears them. This is especially important to do if you have frequently used unusual words, such as a name with an alternate spelling from what is normally in the program's dictionary. One of the great things about the Mac Dragon Dictate program, also, is its ability to do transcriptions of audio files. In fact the reason I am speaking this way is that I plan to use the transcription of this recording as the show notes verbatim without any corrections. The difficulty that most people have with dictation software at least initially is doing things like punctuation and capitalization. You have to remember to do these things or else your transcript will come out without any punctuation or capitalization, unless the words that you are speaking are known proper nouns. It also capitalizes automatically at the beginning of the sentences, so that if you use periods frequently then you will have capitalized words after those periods. You can see that I'm having trouble speaking this text in a fluent way, and this is one of the other difficulties that people have when initially using transcription software. It works best when you can express complete thoughts without pausing, because it learns from the context of your words. It has algorithms that calculate the possibility of one word or another based on the context, and so it is much better to speak entire sentences at one than it is to pause while trying to gather your thoughts. This is a major difference from trying to write at the keyboard, where it does not matter at all if you pause for seconds or even minutes while you think of what you want to write next. Anyhow, I highly recommend using some kind of dictation software if you suffer from repetitive strain injuries like I do. This will save you many thousands of keystrokes. Even if it's only using the speech recognition that's available on your phones over the web, that's better than nothing. The disadvantage of any of these services that have to send your recording over the web to \nget a transcription and then send it back into your device is that they will never learn your voice and your particular speech patterns. In order for that to work best, you really have to use a dedicated standalone speech recognition program that resides locally on your computer and saves your profile and learns from your speaking. Well, I guess that is about it for today, I hope you have enjoyed hearing this brief lesson on dictation. See you next time!

                                                            I don't know if I'm ignorant and everyone else already knows about this, but I decided to record a quick show about Audacity \"Label Tracks,\" something I discovered while working on another HPR episode today.

                                                            The label track is one of the most useful things I've found in a long time. It allows you to annotate your audio project so that you can quickly see important spots or summarize the contents of whole segments and see at a glance what they are about without hunting all over the place and playing things back, trying to find the part where you were talking about X,Y, or Z. You can also export the labels as a plain text file with exact timestamps. I have not tried this, but according to the documentation you can also use labels to mark the beginnings of separate songs in a long track and export multiple separate files at once from a single source based on the labels.

                                                            \n\n

                                                            To add a label track, go to the Tracks menu and select Add New --> Label Track, and it will add the label track to the bottom of your list of tracks. To add a label, either stick the cursor where you want the label to be and press ctrl+b to add text, or select a region to label by clicking and dragging over a region in the label track, then do ctrl+b to start typing the label text.

                                                            1. Find used Netgear WNDR3400 router on shelf at local Goodwill store, priced at $3.99.
                                                              2. \n\t
                                                            2. Use my smartphone to check the dd-wrt database to see if this router is hackable.
                                                              3. \n\t
                                                            3. Grin broadly upon seeing the green \"Yes\" beside router WNDR3400.
                                                              4. \n\t
                                                            4. Double-check that power supply is included, find an AC outlet and plug in to be sure it powers on and my phone sees its ESSID. Yep and yep.
                                                              5. \n\t
                                                            5. Take router to cashier and purchase.
                                                              6. \n\t
                                                            6. Do hard reset of router to clear any previous configuration.
                                                              7. \n\t
                                                            7. Hook a laptop up to router using ethernet patch cable (turning off WiFi adapter on laptop).
                                                              8. \n\t
                                                            8. Access router's configuration in web browser at default router address of 192.168.1.1 just to confirm that it works.
                                                              9. \n\t
                                                            9. Go back to the dd-wrt router database and find the router again, then download the corresponding \"mini\" and the \"mega\" versions of dd-wrt firmware (The mega version has the most features—including USB support, which I wanted—but on many routers, including this one, you have to install the mini version first or else you could brick the router)
                                                              10. \n\t
                                                            10. Read over the dd-wrt wiki page for this specific router just to see if there's anything unusual about the hack. There's not.
                                                              11. \n\t
                                                            11. Go to the router's stock configuration page again and find the \"Firmware upgrade\" button.
                                                              12. \n\t
                                                            12. Click the button and choose the \"mini\" version of the dd-wrt firmware, and click upgrade, then wait while crossing fingers until it says firmware successfully upgraded.
                                                              13. \n\t
                                                            13. Refresh the configuration page at 192.168.1.1 and see the new dd-wrt configuration interface.
                                                              14. \n\t
                                                            14. Pat myself on the back because I have just hacked another router. Hray!
                                                              15. \n\t
                                                            15. Find the upgrade firmware area on the new dd-wrt interface, and this time choose the \"mega\" firmware file and submit, then wait and cross fingers as before. Celebrate when it works.
                                                              16. \n\t
                                                            16. Configure newly hacked router as wireless bridge (this is NOT going to be my main router), enable the USB and printer support, hook up our formerly-usb-only printer to the router, and configure household computers to be able to print wirelessly to the newly-networked printer.
                                                              17. \n\t
                                                            17. Enjoy kudos from appreciative family.

                                                            In this episode I want to look at more movement commands and how to use them in conjunction with commands that change things in the file. I also want to add some more elements to the configuration file we have been building over the last few episodes.

                                                            \n

                                                            I have covered a lot of ground in this episode, introducing a number of new subjects. This is partly because I felt the series needed to get to the point where you could start to make full use of Vim if you are following along, and partly because the episodes up to this point have been moving a little too slowly! I hope the change in pace and length hasn't put you off.

                                                            Magnatune is an American independent record label based in Berkeley, California. It was founded in 2003 by John Buckman.

                                                            \n

                                                            When first set up music could be bought from Magnatune through a download interface on the website with a "pay what you like" pricing model. Later it was possible to purchase physical CDs and in 2007 complete albums and individual tracks could be bought through Amazon.com.

                                                            \n

                                                            Magnatune moved to a membership plan in 2008 and in 2010 dropped the CD printing service. The subscription model offers monthly or lifetime membership. Members can download as much as they want, or with a streaming membership can stream as much as they want. Many download formats are available and all music is without DRM.

                                                            Magnatune encourages buyers to share up to three copies with friends. All of the tracks downloaded free of charge are licensed under the Creative Commons Attribution-NonCommercial-ShareAlike (BY-NC-SA) License.

                                                            \n\nIn addition to my piece here, I also want to use this opportunity to point out an excellent podcast about vim, that's complementary to the series on HPR.
                                                            \nI was pleased to see recently that Thomas Gideon's The Command Line podcast is back from a hiatus and want to make sure that others are aware. His 12th of April podcast is an essay entitled \"Hope and Fear in the World of vim\" where he discusses his use of vim throughout his career as a programmer. You can find this podcast at thecommandline.net
                                                            \n\nThe text editor vi was written long ago by Bill Joy in the late 70's before the advent of the PC keyboard and cursor keys, so the default key mappings for left/down/up/right being H,J,K and L are not immediately familiar to a pc keyboard user.
                                                            \n\n\"AD-M3A
                                                            \n\nThe original UNIX machine for which vi was written used the AD-M3A terminal where H,J,K and L had the cursor arrows engraved.
                                                            \nVi is installed as a default choice on many distros, and where it is not, there is invariably a package available that can be easily added.
                                                            \n\nSome, if not most, distros come vim installed by default (vim by the way stands for vi improved). This does have the cursor keys mapped nicely for a modern PC keyboard as well as the original keys. Vim is always aliased as vi, so if it's been installed when you enter vi you get vim.
                                                            \n\nVi is a pretty light weight bit of code whereas VIM has more dependencies so sometimes vi is still preferred as the default install package. For instance Debian and many of its derivatives have vi rather than vim installed by default.
                                                            \nIf you are distro hopping or working on other peoples systems you can generally rely on having vi available, but you can't be sure to get vim so it is useful to be conversant with the vi key mappings, along with a working knowledge of some of the basic commands. Then you will never be at a loss for a text editor when needing to hack around in a Linux box.
                                                            \n\nFor me as an occasional user of vi the most challenging keys to remember to use are the H,J,K and L. cursor keys, since muscle memory has my fingers diving for the arrow keys. This is where the game Nethack comes in, which is what this article/episode is really about.
                                                            \n\nNethack is a terminal based dungeon adventure games which uses the same cursor keys as vi and other old UNIX programs. Play this game for a few hours and you will ever struggle with vi cursor keys again.
                                                            \n\nThe goal of the game is to retrieve the 'Amulet' from the lowest level of the dungeon and return to the surface with it for your god.
                                                            \n\nNethack presents as a text based adventure with each level gradually being revealed to you in the on-screen character based level map. As you travel through the dungeon more of the level is revealed. As you play, your character gains more experience and levels up its capabilities.
                                                            \n\nYou play as one of a number of types of character, and race. These include many of the usual dungeons and dragons types, archaeologists most likely inspired by Indiana Jones and tourists which definitely owe much to Terry Pratchet. Each role and race has their own initial characteristics, default inventory items, levelsof resilience and ability to learn various skills. For instance a wizard will advance his spell making capabilities faster than a footpad.
                                                            \n\nAlthough seemingly a simplistic terminal based game there's more going on in Nethack than is at first apparent. Originally released in 1987 it was actively developed with improvements to game play features until 2003. Since then there have been minor updates and ports for different platforms have been added, however there is rumoured to be a release with further game play improvements some-time this year.
                                                            \n\nThe game has real depth and subtlety that is gradually revealed the more you play. It is not an easy game to win (from my experience to date that may not even be possible) but the more you play it the better strategies you will devise and the more rewarding the game becomes. There's more complexity to this game than almost any modern 3d HD graphic adventure.
                                                            \n\nAlthough there is a Nethack Wiki where information about how to play can be sought, the true elite apparently learn through playing. I'd suggest having a go, then when you become familiar with YASDs (yet another stupid death), there's a lot of them, you will have enough experience to answer a few burning question with the Wiki in order to be able to play a more satisfying game.
                                                            \n\nAlthough a challenging game, it is not a difficult game to play once you have remembered a few keyboard commands. And this game can be played just about anywhere. Because the game has GPL license there are many ports and flavours available. It is possible to play on most platforms: I have tried it on Linux, Android and even as a Google Chrome app, although the IOS port was not usable on our old iPad or a colleague's new iPhone.
                                                            \n\nThere are various ports for the Windows platform, some of which replace the character based interface with Windows 3.1 style tile interface or a 3d isometric graphic interface. Personally I'd prefer to stick with the traditional character interface since the graphics don't really add anything to the game play. In fact when I play the game on Windows laptop, I use a minimal Debian install running on VirtualBox. I have set it up to auto-run Nethack and shutdown when exiting the game. Then I launch the VM directly with a shortcut containing the virtualbox command on the desktop.
                                                            \n\nThis is how I set up my Nethack VM:
                                                            \nFirst I created a VirtualBox VM with 1 core 256M of RAM and an 8GB hard drive (I could have easily got away with 2GB actually).
                                                            \n\nThen I installed a minimal install of Debian, configured networking and installed nethack using apt-get install.
                                                            \n\nOnce nethack was installed I disabled networking so I don't have to wait for a network connection to time-out when if my machine is not online.
                                                            \n\nTo make Debian auto-start with a particular user account you can edit the /etc/inittab and alter one of the tty invocations. I changed the line:
                                                            \n\n
                                                            1:2345:respawn:/sbin/mingetty tty1

                                                            \n\nTo login my account 'steve'
                                                            \n\n
                                                            1:2345:respawn:/sbin/mingetty –autologin steve tty1

                                                            \n\nTo get Nethack to run on start-up, and the vm to shutdown on exiting the game edit the user's .bashrc file and append these three commands to the end of the file
                                                            \n

                                                            \nclear          # this ensures that the screen is clean prior to running the game
                                                            \nnethack    # to run the game
                                                            \nsudo shutdown -h now  # to close the VM when you exit the game
                                                            \n

                                                            \n\nBecause Nethack is a terminal based game it doesn't hammer the battery in portable machines, making it an ideal travel game for a commuter.
                                                            \n\nEven if you are not a gamer its worth a look at Nethack, it might be the one computer game that really grabs your attention.

                                                            \nThis is a story of my last days as a Windows Users at home and my eventual switch to Linux. My name is Kevin and my online name is GNULinuxRTM. The name GNULinuxRTM was recently created for a project I am working on. But maybe Ill talk about that another time.\n

                                                            \n

                                                            \nAlthough I listened to every single episode of Linux Reality, many episodes of Linux Outlaws, Linux Link Tech Show, The Bad Apples aka GNU World Order, and other Podcast shows, I just recently listened to my first episode to Hacker Public Radio. What caught my attention was the plea for content to keep Hacker Public Radio going. So I have been HPR binging and I have to say that the fact that this kind of Podcast format exists, is amazing.\n

                                                            \n

                                                            \nYes, I had heard the words Hacker Public Radio before, but I just thought it meant that this was some kind of show for extreme Hacker types, which I didnt think described me.\n

                                                            \n

                                                            \nAnother confession, my day job is mostly in a Windows environment. And although I kept myself up to date on the progress of Linux, I had very few opportunities to use Linux at work. I had enough challenge keeping up to technology I had to know to do my job. Although I heard and understood the significance of making a commitment to use Linux, I never did make the switch. Sure I dabbled with Linux as a Server platform and maybe to get some use out of some old hardware. But not on my most powerful and most used home machine. The computer I use every day for my own personal projects was, until last Summer, a Windows PC.\n

                                                            \n

                                                            \nYou see I hate wasting effort and time, something we all have a limited amount of. I remember after a particularly frustrating bout with Linux I turned to a Co-Worker and said \"Windows, because Lifes too short\".\n

                                                            \n

                                                            \nAlso, I am one of those weirdos who loves the little red Trackpoint on IBM Thinkpads. Last Spring I traded in my old Thinkpad plus some cash for an off-lease Lenovo Thinkpad W510 Notebook. I got it cheaper because they didnt have the original power supply, instead it came with a 3rd party power supply. Eventually it got to me that it took more than twice as long to charge the notebook, so i spent the money to replace it with a higher wattage power supply. \"In a for penny, in for a pound\", why not upgrade to 8Gb of RAM too.\n

                                                            \n

                                                            \nShortly after the 90 day warranty I started having weird lockup issues. The hard drive light would go solid and the machine would just freeze. Ive seen this before. Suck it up and back to local computer store to replace the Hard Drive. But \"In for a penny, in for a pound\", why not get one of those slick new SSD drives. Got home, do a drive copy and I am back in business Or so I think. After a while I realize I am still suffering from intermittent Lockups. Time for a fresh install.\n

                                                            \n

                                                            \nInstall Windows 7, Windows Update, Reboot, Windows Update Reboot, Windows Update Reboot almost done. Blue-Screen-of-Death. Reboot, Blue Screen of Death. Start over, Re-install Windows 7, trickle install Updates, Save System State, Reboot, Repeat, Blue Screen, Ahhhhh!!@!!! System Restore, its that update, Blue Screen, not its that update, Blue Screen, Blue Screen, Blue Screen Ahhhhh!!##$\n

                                                            \n

                                                            \nIs it my new RAM, switch that out. No difference. Power Supply? Nope. Go back to Non-SSD drive? Still No Change. Different Windows Install Disc? No, No and No. \n

                                                            \n

                                                            \nNow Im really \"In for a Pound\" with this machine and I cant use it. Deflated, I put the computer down in the corner of the room and try to forget about it. The sleek black Thinkpad just sits there mocking me every time I walk by, but I am determined to ignore it. Weeks go by, now a month. Ive gone back to my desktop, but its no use, I miss having a notebook. Im an easy-chair Notebook guy now. I dont want to regress down the evolutionary scale and hunch over my desktop anymore. Im at home, I should be reclining!\n

                                                            \n

                                                            \nLike a bad hangover, time has numbed the memory of the pain. I pick the Thinkpad, its time to drink again! Im back baby and Ive got that \"You cant beat me\" Techy Battle cry pumping through my veins. \"LINUX! Ill try Linux!\" At least that is the way I prefer to remember it. But really, I was thinking that Ive spent sooo much money on the piece of Crap, Ill use it even i have to switch to Linux.\n

                                                            \n

                                                            \nLets see Ive got to approach this logically. Uhhh, choose a Distro, Desktop, hmmmm. Video on Richard Stallman spanking Ubuntu on Amazon Deal, hmmm. Ok, Linux Mint 17 is based on the LTS release of Ubuntu, 5 years Support, Cool! Top of the Distrowatch charts. Looks like a good start.\n

                                                            \n

                                                            \nI install Linux Mint 17 and it is up and running in no time. Run the Update Manager and hold my breath. Wow! It updated 100%, no Crash Screen of Doom!\n

                                                            \n

                                                            \nNow what? What do i do now? Google \"First things to do after install Linux Mint 17\", wow Direct hit, Yeehaw! Oh cool, Steam Games, Yummy. PlayOnLinux, Bonus! What a blast. But the fun of discovery was better than any game I played.\n

                                                            \n

                                                            \nAlas, my machine was running great but still had a locked up issue, just not as often. But it was a victory nonetheless. Besides, I had a mostly working machine and I would just ignore the problem. An infrequent lockup didnt seem to bother Linux Mint, it just boot back up fine.\n

                                                            \n

                                                            \nAfter about a month on Linux Mint a little message popped up, I cant remember exactly what it said. But it was like machine was talking to me. \"Hey Buddy, this battery in your notebook, uhh it kinda sucks. And you might want it replace because well I need steady power to you know, breath. And it sure would be a lot easier if I could Huh Huh Huh AHHHHH count on some steady air flow\".\n

                                                            \n

                                                            \nYeah, you know I was elated, but even more so amazed! I had installed no diagnostic software, I had spent no additional time troubleshooting, I had just installed Linux and started using it. And my computer just told me what was wrong with it.\n

                                                            \n

                                                            \nNew battery arrived and now the machine is solid as rock. Did I go back to Windows 7, Hell No! I had kicked the habit once a for all and I was not missing Windows at all.\n

                                                            \n

                                                            \nI distinctly remember a standout moment when I was working on my brother-in-law's wedding video. Circumstances were that the key family members could not be at the Wedding and the they were anxiously waiting for the Wedding Video. I didnt want to delay finishing the project and was reluctant to do anything else with the computer during the Render process. Rendering the Video took quite a bit of time and was very CPU intensive. But I had broken the Wedding into several segments and there was lots of Rendering and getting feedback. \n

                                                            \n

                                                            \nKdenlive lets you assign how many processors would be used during Rendering, and I had set that to four. There were processors to spare, maybe I can do something else while I am waiting for the Render.\n

                                                            \n

                                                            \nIll read a few emails. Hey, I dont notice any performance difference. \nMaybe Ill surf a bit. Still fine. Youtube Video, smooth, now in HD, wow! no problem or no slow down. Multi-tasking as it should be!\n

                                                            \n

                                                            \nNext day at work, I cant help but talk about it with my Co-Workers. \"Why not get a Mac?\" they say. it wasnt a question, it was a strong suggestion. Most of them had written off Linux years ago. I start talking about how great my system is working for me and how I have been able to get so much done with 100% open source applications.\n\"So what\", they say. \"You can install most of those applications on the Mac and Windows as well\". \n

                                                            \n

                                                            \nIts no use, I guess I am not much of an evangelist. Or maybe I just work with cynical people. But it does cause me to question. Why am I so excited about Open Source Software now? At this point in history. Really most of the fundamental building blocks of Open Source Software have already happened. It seems to me we are now in a fine tuning stage.\n

                                                            \n

                                                            \nI think it is that maturity that appeals to me. No longer do you have to say, you can install Linux, BUT. And word \"But\" lands with a thud. There is very little creative work that you cannot do on Linux and Open Source software, right now.\n

                                                            \n

                                                            \nI dont regret a single moment I have invested in switching to and learning Linux.\n

                                                            \n

                                                            \nMy story continues, but well save that for another time. I hope to tell you more about my project and the hurdles Ive gone through in a future HPR episode.\n

This allows for legal remixing and sharing, and also makes it perfect for stuff like I do in this episode—cutting the recordings up for inserting as musical examples and then presenting the whole thing for your listening enjoyment.

                                                            What is MapReduce, Anyway?

                                                            \n\n

                                                            MapReduce is inspired by three approaches from\nfunctional programming for applying a function to each item of a\ncollection of data, namely, Map, Filter and Reduce. That is pretty\nabstract, so I will try to bring some of these ideas down to Earth.\nI'll use lists to represent the “data” in any examples, but the\nconcepts in MapReduce can apply equally well to any data source:\nmultiple streams from the Internet, a number of internal data stores\nfrom multiple sites, and even user keystrokes/mouse moves.\n

                                                            \n

                                                            If a function (or operation) can be applied to\neach item in some kind of input data, you may be able to use map,\nfilter and reduce.

                                                            \n\n

                                                            Defining Terms

                                                            \n\n

                                                            Map

                                                            \n

                                                            When we use the expression\nMap(function: f, data: [1,2,3,4,5,6]), we are declaring that we want\nto apply the function \"f\" to each element in the data. In\nthis case, we have a list of numbers, but the data could be names,\nemployee records, or URLs for Internet documents from the Internet\nthat we would like to parse to extract useful information.

                                                            \n

                                                            Example: function f is square(x) = x * x, and the\ndata is our list [1..6].

                                                            \n
                                                            \nMap( square(x), [1,2,3,4,5,6]) = [square(1),square(2), ..., square(6)], or [1, 4, 9, 16, 25, 36]\n
                                                            \n

                                                            Filter

                                                            \n

                                                            Filtering data is essentially a variation of Map.\nYou could think of it in two stages:

                                                            \n
                                                              \n

                                                            1. Apply a \"test\" function to Map each item to either True or False (\"In\" or \"Out\")

                                                              2. \n

                                                            2. Use the results of that Map operation to drop any item that fails the test (False)

                                                              3. \n
                                                            \n\n

                                                            Having said this, a Filter does not have to be implemented in this way. By\ndeclaring that we want to use a Filter operation, we have specified WHAT we\nwant to do. It really does not matter HOW it gets done.

                                                            \n\n

                                                            Most functional programming tutorials would illustrate a Filter by\nselecting prime numbers from a list of integers, or to isolate numbers that\nare not multiples of 3. A more useful illustration of Filter is a search\nfilter that reviews documents in a repository, or a set of search engine\nresults, and returns only those that pass the \"relevance test\". The test\nitself could be defined using a \"fuzzy\" criterion for relevance (0-20% Not,\n20-50% A Little, 50-75% Fairly, > 75% Very -- or what have you), but the\nend result is that you'll choose some documents to accept, and omit the\nrest.

                                                            \n\n

                                                            In a filter operation on a large number of data items, you might want to\ndrop the items as early as possible. There is no law that requires you to\nmake these decisions in advance when you offer Map or Filter operations on\na server.

                                                            \n\n

                                                            In a MapReduce context, Map and Filter will often end up lumped together.\nThis is fine, because you don't want to waste processing time to perform\npotentially expensive transformations on data or documents that you can rule\nout immediately with a less computationally expensive filter.

                                                            \n

                                                            Reduce

                                                            \n

                                                            A Reduce operation on a collection of data is any\nkind of aggregate operation that boils down all of the detail items\ninto one or more summary metrics computed on the (filtered) data.\nThe canonical examples of a Reduce operation would be a Sum or a\nCount, but there are other possibilities.

                                                            \n\n

                                                            Reduce is usually defined as an operation:\n

                                                            \n\n

                                                            Reduce(function(accumulator, data item) -> new\naccumulator value; initial value; data).

                                                            \n\n

                                                            Sometimes, you may see the Reduce operation\ndefined recursively:

                                                            \n\n
                                                            \nReduce( function: f, initial_value, data = {first_item, all_other_items} ) is equal to\nReduce ( function: f,  new_value = f(initial_value, first_item),  data: {all_other_items})
                                                            \n\n

                                                            If you follow that script, you can just\nrinse-and-repeat until you've processed all of the items.

                                                            \n\n\n

                                                            Why is this some kind of technological advance?

                                                            \n\n

                                                            If you look at this characterization of Map and\nReduce, you'll see that these operations are fairly abstract. The\ndeclarations typically state only what needs to be done, and the\nimplementation steps that specify how it is to be done are left open.

                                                            \n\n

                                                            For operations on data items that are fairly\nindependent of each other, there are advantages in defining things in\nthis way. If there are no dependencies between data items, in the\nsense of the two rules listed below, you can use distributed\nprocessing across several \"servers\" to get to the result\nfor the entire data collection much faster.\n

                                                            \n\n

                                                            Basic ground rules for the simplest case\n(Exceptions and additional constraints will apply in real projects):

                                                            \n\n
                                                              \n

                                                            1. Computations for each data item do not depend on those for other data items, so no communication, coordination or shared memory is needed between \"worker\" machines.

                                                              2. \n

                                                            2. The order of the computations does not matter.

                                                              3. \n
                                                            \n\n

                                                            Under these conditions, Map and Reduce operations\ncould be outsourced from a MapReduce server installation to a fleet\nof \"worker\" computers that can take on pieces of the\noverall computation, and send their results back to the Aggregation\nServer (or \"Boss\" machine). That could give you a\ntremendous speed-up over the alternative of running on a single\ncomputing cluster. So there can be speed advantages that come from\nMapReduce.

                                                            \n\n

                                                            With the right infrastructure, you can relax these\nconstraints and still get many of the same benefits on data that\nneeds to be ordered or preprocessed into some kind of table\nstructure.\n

                                                            \n\n

                                                            Another advantage of the Boss/Workers paradigm for\nMapReduce operations, which may be less obvious, is fault tolerance.\nComputers sometimes fail to complete their assigned tasks. Network\nconnections can be lost. In a Boss/Workers setup, a Worker could\nsend a status report back to the Boss machine (or a Supervisor, since\neven the Boss role can be shared) that either contains a SUCCESS\nstatus flag and the results of its assignment, or a FAILED flag.\n

                                                            \n

                                                            If a Boss receives a FAILED message, that piece of\nthe overall computation could be re-assigned to other Worker(s). In\nthe case of a network outage, the Boss could respond to a Timeout\nevent for the Worker, flush that assignment to that Worker, and\nre-assign the unfinished task to other resources with a new unique\nID. Any homework that is turned in after the Timeout event can then\nbe ignored.

                                                            \n\n

                                                            Note: This is just one way to build in parallelism\nand fault tolerance.\n

                                                            \n\n

                                                            An additional advantage to this sort of vague\ndefinition of MapReduce tasks is the ability to work with distributed\ndata in a way that allows greater use of local processing. A central\nserver (Hub) processing model forces remote sites to transmit all the\noriginal data to the Hub, wait for the Hub to do the processing, and\nthen possibly transfer the processed results back from the Hub to\nthe remote data repository. That's a lot of network traffic, any\npart of which could be lost, corrupted or even intercepted by third\nparties.

                                                            \n\n

                                                            In a Reduce operation, where everything is boiled\ndown to some [set of] summary measures, the local site could do much\nof the processing work, and transmit only the needed intermediate\nresults to the Boss back at the Hub for inclusion in the final totals\nover all Worker machines.

                                                            \n\n

                                                            Summary: Leaving the implementation details out of\nthe MapReduce specification allows for flexibility and some degree of\noptimization in getting these operations done in the most beneficial\nway.\n

                                                            Whatever your objectives, you can adjust your\nimplementation to get the best result for your application.

                                                            Enter Hadoop.

                                                            \n\n

                                                            Hadoop is an open source project from the Apache\nFoundation that lets you set up massively parallel distributed\nprocessing schemes for computations that can be fit into the\nMapReduce paradigm. The best part is that you can make Hadoop work\non varying types of hardware, so you don't need to run the pieces of\ncomputational work solely on high-end, expensive supercomputers or\ncomplex computing cluster installations.\n

                                                            \n\n

                                                            Hadoop makes it possible to farm out the bits of\ncomputational \"homework\" to \"commodity hardware\"\n– whatever that may mean for your installation. Commodity hardware\nis also an abstract term. In practice, you can match the level of\ncomputing power for Workers to meet the requirements of the assigned\nwork. The worker machines could be set up on computers that are\neasy to provision and replace, so you won't have to buy\nspecial-purpose servers that require extended periods for setup and\nconfiguration.\n

                                                            \n\n

                                                            MapReduce does NOT refer to the process of\nsplitting up a large data processing job into assignments. The\nconcepts behind MapReduce help us to think about and plan classes of\nprocessing tasks that are frequently applied to large datasets, or to\na lot of data streams that are coming in from many sources and\nlocations.\n

                                                            \n\n

                                                            So far, it sounds like MapReduce and Hadoop are a\nkind of silver bullet that can eliminate the time and expense\nrequired to solve “Big Data” problems. As helpful as these ideas\nand their supporting technologies may be, not every potential\nMapReduce job can be optimized as much as we might like. Hadoop\nwill not offer a cure-all for every problem.\n

                                                            \n\n

                                                            We still have to understand the problem, determine\nwhat is needed, and work hard to do the right thing.

                                                            \n\n

                                                            But when there is a good fit between the problem\nand this approach toward providing a solution, Hadoop and MapReduce\ncan be very helpful.

Honestly I forgot all about it until now when the HPR queue is low again. I apologize for the slightly clippy quality of my audio, I must have had my microphone too hot on the mumble. It's really interesting to listen to this conversation a year later because I have worked out so many of the problems that I was mentioning to Mike, including the automation of the entire build process using command-line tools from Calibre.

                                                            1. Organize photographs in a folder structure that makes sense to me, e.g. 2015/2015-05-22
                                                              2. \n
                                                            2. Allow me to back up my photographs using a variety of methods.
                                                              3. \n

Unlike one-time fundraising campaigns that help projects get started, Snowdrift.coop pays out monthly to provide sustainability for ongoing work.\n

With Snowdrift.coop, the global community becomes the patron. Instead of businesses deciding the options that we then merely choose from as consumers, we will support and actively work with projects that best serve the interests of the public.\n

                                                            On GNU Social

                                                            \n\n

                                                            Here is the basic format for the command to post a message to a Statusnet / GNU Social timeline:

                                                            \n\n

                                                            curl -s --basic --user <username:password> --data status=\"Hello World\" --output /dev/null https://instance.domain.com/api/statuses/update.xml

                                                            \n\n

                                                            And here is the script I use to post a message to my timeline, launched by a blather voice command:

                                                            \n\n

                                                            \n\n

                                                            On Pump.io

                                                            \n\n

                                                            On pump.io you have to install the pump.io software on your computer. You don't have to be running a server, you just have to have the binaries so that you can run the commands. I will not go into how this is done on this podcast, but there's a link to the pump.io website below and there should be installation instructions available there. Once you have the software installed, you also have to allow command-line access to your account and get the token for authentication, maybe authorize the user too:

                                                            \n\n
                                                            \npump-register-app -s instance.domain.com -P 443 -t CLI\n
                                                            \n\n
                                                            \npump-authorize -s instance.domain.com -P 443 -u username\n
                                                            \n\n

                                                            Finally you can post to your timeline from the command line:

                                                            \n\n

                                                            pump-post-note -s instance.domain.com -P 443 -p -u username -n \"Hello World.\"

                                                            \n\n

                                                            My script to post a message to the pump.io timeline, launched by a blather voice command:

For many people that might mean Netflix or Hulu, but for me it means YouTube. This is the golden age of narrow-casting, as opposed to broadcasting, because YouTube gives so many creators the opportunity to find their own audience for things that dont appeal to the masses.\nFor more go to https://www.palain.com/?p=243\n

                                                            \nWe have previously looked at Styles for Writer, and for Calc, and now it is time to look at them for Impress. You may recall from both Writer and Calc that we saw it is important to know that Styles live inside of Templates. So any time you change a Style you needed to make sure it was saved inside of a Template, and if you wanted it to be generally available in all documents or spreadsheets you needed to be sure to make the change inside the Default Template.\nFor more go to https://www.ahuka.com/?page_id=1125\n

I know I received questions because I have recommended LastPass often, and my advice has been to stay with them.

                                                            \nSurf is a lightweight, graphical browser. It uses the webkit rendering engine, and is a GTK-based application (not that you can tell). It is extremely spartan. Part of the suckless project, surf takes the Unix philosophy to it's extreme.\n

                                                            \nEssentially, you only get a single browser window. No tabs, bookmarks, or other interface to speak of. Any navigation is accomplished through links on the page, or some very rudimentary keyboard shortcuts. Ctrl+H goes forward in history, and Ctrl+L goes backwards. If you want to visit a URL, you can either send it as a command-line argument, or use Ctrl+G to bring up a drun-like text input. It is perfect for lightweight system configurations, surf does the bear minimum to qualify as a web browser.\n

In it, you are given a square of alien landscape, dotted with steam vents, and a small settlement at the center. This settlement runs on the steam so abundant on this alien world, and it's your job to keep the steam flowing.\n

                                                            \n

                                                            \nThe game consists of building steam nodes, which capture steam from the vents, and connecting them back to your settlement. Of course, you can't simply build a straight pipe back to your settlement; the length of the pipe is taken into account, and the longer the pipe, the harder it is to get steam to travel through it. You can get around this by daisy chaining nodes together in a web, and providing multiple routes back to your settlement. Running a steam-powered base on this alien planet isn't without its share of dangers, however! There are aliens, inclement weather, and seismic instability that can all damage your network of steam pipes and nodes. If your steam pressure falls below a certain threshold, you lose. \n

                                                            On Nautilus you have to put your scripts into the Nautilus scripts folder, which on my system is located here:

                                                            \n\n

                                                            \n\n

                                                            You can either put copies of the scripts in there, or you can do like I did and make symlinks from the Nautilus scripts folder to your /home/bin folder. (I prefer to make symlinks instead of copying the files in there, just in case I make any changes to my scripts. If I have made a symlink instead of copying the file, then I only have to change original script and the symlink will automatically use the updated version.) Once you've done that, you right-click on a file and choose scripts then <yourscriptname> to run your script on the file.

                                                            On Thunar you don't have to put your scripts anywhere special. It actually handles custom actions much better than Nautilus, in my opinion. What you do is go to the Edit menu and choose Configure custom actions. Then you get a dialog box with two tabs. The first tab is where you can give your custom action a name and then tell it what command to run, and also tell it whether to apply the custom action only to the selected file, to all files in the directory, or to all selected files. On the other tab you choose the context in which this custom action will appear. You can select categories of files—like images, audio files, or text files, and so forth—or you can specify filetypes by extension, so that your custom action will only appear if you right click on a file that has the extension.

                                                            As you know, HPR asks for tags to be added to the episodes we contribute. These are intended to be used to produce some kind of improved topic search at some point in the future.

                                                            \n

                                                            I find it difficult to decide what tags to add to my shows, and I expect many people feel the same way about it. Should I use common tags like Linux or does that not differentiate it enough? How many tags should I add, should the words be plural or singular?

                                                            \n

                                                            We have recently been asked to contribute to the task of adding tags to previous shows, so it's very much a hot topic at the moment.

                                                            \n

                                                            In thinking about this I wondered if there was a way in which existing tags could be represented in a visual way to help with the process of choosing and rationalising tags. It was the type of thought that occurs to you in the shower or while out for a walk.

                                                            \n

                                                            In my last job I occasionally used a package called GraphViz to generate graphical representations. I used it to generate a chart showing how the organisation (a university) was divided up into schools, departments, sections and so on in a hierarchical manner. I wondered if it could be used for this task.

                                                            \n

                                                            I decided to use my currently preferred scripting language, Perl, and found there was a module which let me access GraphViz. I started putting together a script.

                                                            \n

                                                            The script was created in an evening and is still rather rough. It performs a very simple query on the database to obtain the show numbers of shows with tags, their titles and their tags. It then uses a CSV parser to parse the tag list and builds a hash table indexed by tags, where the contents per tag are the show numbers that use this tag.

                                                            \n

                                                            Having built this hash table it is used to generate GraphViz data by making each tag and each show number a node and joining them together.

                                                            \n

                                                            Finally the script processes the graph to produce output in SVG format which is available to view.

                                                            \n

                                                            Bear in mind that this is not a finished project - it may never be finished! The script may not be ideal. My understanding of GraphViz may be insufficient, and the rendering of the SVG may not be good (I got various results on different browsers).

                                                            One of these things is how to create horizontal lists in LibreOffice. This is something that I wanted to do, I think it was maybe a year ago that I was really trying to find out how to do this. What I mean by that is I wanted to be able to do in LibreOffice the equivalent of an in-line list in HTML and CSS. There's a way in CSS to tell the browser to display a series of list items in-line rather than vertically—and this is used all the time for footers and headers and things of that sort—and I wanted to be able to do that in LibreOffice because it would ease the process of creating the exams that I make in my classes, where I have a numbered list for all of the questions, and the answers for each question are also done in a numbered list but at the 2nd level—usually done with a, b, c and d, whereas the numbers of the questions are 1, 2, 3, 4, and so forth. What I wanted to be able to do was have the ordered list a, b, c, d spread out horizontally across the page without having to do it manually. So in other words I wanted to be able to type a word for an answer and then press enter, and instead of having it go into a new line, have it simply move over to the right a little bit with a new letter in place for the next item in the ordered list. I hope it's clear what I'm after here.

                                                            \n\n

                                                            Anyway I never did find a way to do this. I searched online and there were a couple of other people who were interested in doing the same thing but they were all told this is impossible. Well, sort of. I found a workaround for this and it's not all that elegant but in a pinch it could work, and I don't think I would want to do it for an entire test but I thought it was kind of a cool way to do it.

                                                            \n\n

                                                            So what you do his make up the ordered list just like usual. I have here on my computer right now opened a document with a single question, question no. 1. And then it has at the 2nd level of ordered list a series of 4 options: red, purple, green, and blue. And each one of these is in a font color of the same name, so that the word \"Red\" is red, the word \"Purple\" is in purple, \"green\" is in green. I do this because it makes it easier to see how these things move up and down. There are little buttons down at the bottom of the screen where if you click on the arrow up or the arrow down, it will move the list item up or down. So right now red is in the 1st position, but if I click the down arrow it will go down to the 2nd position and the one that was formally 2nd is now 1st. So purple and red have switched places.

                                                            \n\n

                                                            I want to have this kind of flexibility going horizontally as well, and the way I found to do this was to use columns. I select the 4 items and then under the Format menu choose Columns and tell it I want 4 columns because I have 4 items, and I click OK and suddenly these things are distributed across the screen horizontally. Now if I click the up arrow, the item moves left and right!

                                                            \n\n

                                                            The bad thing about using columns is that the columns are of uniform width, so they do not dynamically change according to the number of characters that are in the word the way it would do in HTML with CSS.

                                                            \n\n

This kind of commitment to service naturally requires are larger number of people working tech support, and by the end of the weekend I think it was clear to everyone Rackspace was in Kansas to recruit. I was impressed when one of the Rackspace representatives told me, \"We can teach people tech. We can't teach people to want to help other people\". Rackspace dedicates a significant part of employee time to training and improving the skills of their help desk staff. If there is a drawback it's that when one shift is training, the other two are expected to pull extra hours to cover the third shift.\n

                                                            I like to use images in HPR shows if I can. I have experimented with various ways of preparing them since I first started contributing, but I'm particularly impressed with what I am able to do using ImageMagick.

                                                            \n

                                                            The ImageMagick system contains an enormous range of capabilities, enough for a whole series of shows. I thought I would talk about some of the features I use when preparing episodes to give you a flavour of what can be done.

                                                            \n

                                                            I'm the rawest amateur when it comes to this kind of image manipulation. Just reading some of the ImageMagick documentation (see links) will show you what an enormous number of possibilities there are. I am only using a few in this episode.

I wouldn't go as far as to say I'm learning it properly—that's not really my way—I'm kind of poking around in the dark learning things on an \"as-needed\" basis, but I'm finding that it's incredibly powerful and making me much more efficient in my daily life. In this podcast I discuss some of my favorite ways of using it and some of the cool modules and libraries that I've found that make things surprisingly easy in Python that used to be difficult for me in bash.

(They all mean the same thing, but within Impress they are shown on the Sidebar as Master Pages, so I will stick with that terminology here.) I say we will use some of these concepts because trying to put everything into one Master Page would create a hideous end result.

As a side note, the day I received the Blue Yeti in the mail, I found the same microphone brand spanking new on Amazon.com for the same price as the used one I purchased on ebay.

As mentioned in a recent hpr episode, I actually found myself hypnotically engaged in 5150's whats in my pickup toolbox episode.\nI found myelf cheering on 5150 to come up with a pair of lugnuts to an unknown vehicle.\n

                                                            \nI have to admit, Ken Fallons Amazing life hack episode of how to tell your left earbud from your right, lived up to its claim of setting a low bar. Ken has given some terrific episodes in the past, but this one fell a bit short of his standard of excellence. But I must admit, his goal was achieved.\nAs I listened, I said to myself, even I can top that! And thus, Ken inspired me to step over that low bar of quality he set, and record my own episode.\n

                                                            \n

                                                            \nOne of those listening styles Im vaguely familiar with was listening to podcasts speeded up.\nSomewhere I read about some people really really speeding up their recordings to the point most people can only hear a rapid fire series of blips and clicks. \nI don't know if that is typical, but I'm inclined to think that is something found on the fring, and that most speed listeners fall in the range of 2 to 3 times normal rate.\n

                                                            \nBasically, recording Normally recorded vocal content, with an ultra slow music soundtrack that would balance out with speed listening.\nIn essence, hacking the audio, to provide speed listeners with a soundtrack.\n

                                                            \n

                                                            \nOn the flip side, one could hack the audio to appeal to slow listeners, speeding up the soundtrack, and changing the pitch of the vocals to account for slow listening.\nBut that would probably kill some speed listeners with weak hearts, so I'll steer away from that unless there is enough demand to justify that.\n

                                                            I write almost exclusively in Markdown https://daringfireball.net/projects/markdown when writing documents and taking notes.

                                                            I use Ubuntu because it is the only distro that does not bundle pandoc in the haskell libraries. With pandoc, you can specify the template that you are using, so that the same one document can be formatted quickly in many different ways and file formats.

                                                            How to Hide a Password Using a Password Card

                                                            It's okay to write your password down and keep it in your wallet, but it's best to try to hide it as well. Here's how to keep your password secure and handy at the same time by embedding it in a password card.

                                                            \n\n

                                                            Method 1

                                                            \n\n

                                                            Generate a fancy symbol-and-color-coded password card at passwordcard.org: https://www.passwordcard.org/en. Follow the directions there on how to use it best.

                                                            \n\n

                                                            Method 2

                                                            \n

                                                            Make your own. Use the password generation package pwgen on Linux to generate a whole bunch of random passwords. In the following example, the -s flag tells it you want secure passwords that are generated randomly, not suitable for human memory. The -y flag tells it to include special characters, and 24 indicates how many characters each password should contain.

                                                            \n\n
                                                            \npwgen -sy 24\n
                                                            \n\n

                                                            Then either use one of the passwords that was generated from this command or embed your own existing password somewhere inside the giant block of gibberish such that only you will know where your password begins and ends. You can put a copy of this in your wallet.

In fact, we saw in the previous tutorials that Impress and Draw share a common set of Styles that apply to both programs, and I have often seen in documentation that Impress and Draw are often mentioned in the same breath, so to speak. So it is important that we start developing an understanding of the graphical elements in Impress.\nFor more go to https://www.ahuka.com/?page_id=1217\n

                                                            Today I want to talk about three Bash commands:

                                                            \n
                                                              \n

                                                            • popd
                                                              • \n

                                                            \n

                                                            These let you change directory on a Linux system (and others which support Bash) but keep a record of where you have been in a stack structure. The stack can be viewed and manipulated with these commands as well.

                                                            \n

But I left out one area because the tutorial was already running a bit long, and I wanted to give the Gallery and Themes the full attention they deserve. I think this is something a lot of people have missed when working with Impress, at least I have not seen these elements includes much in peoples presentations. But they are a wonderful addition to your toolkit, and well-worth some attention. Note that the Gallery is a common feature of all LibreOffice applications, and is available in applications like Writer and Calc, though there is less need for it there. It is when you get to applications like Impress and Draw that you really discover how useful it can be.\nFor more go to https://www.ahuka.com/?page_id=1222\n

                                                            W3M is a text browser with image and tab support which supports both keyboard and mouse navigation. (Image support is not available in some terminals, but does work in Xterm and rxvt, but images may be opened in a external viewer)). Mouse and keyboard navigation are supported, but I recommend learning the keybindings. Keybindings are case sensitive.

SSH is an acronym for Secure Shell, and expresses the idea that you can securely log in and get a shell on a remote server. This was initially released as free software, but in later versions he took it proprietary. But the developers at OpenBSD decided that a free software implementation was needed, and they created OpenSSH, which is the basis for most implementations today. \nFor more go to https://www.zwilnik.com/?page_id=722 \n

                                                            \nIn today's show Jon, Dave and Ken discuss some topics such as, \n

                                                            \n\nHi All,\n\nI am concerned as to the health of HPR, and I touched (went on a rant to\nbe honest) on this in the Community News show that will be released\ntomorrow.\n\nWe have 16,495 subscribers and 260 slots per year, so we need to have\nonly 2.5% subscribers contributing to have a different host for every\nday. Unfortunately only 62 managed to contribute a show in the last 365\ndays. I don't need Charles in NJ to tell me that that's only 0.38% of\nour subscriber base.\n\nAs a project that is supposed to be a \"Community Podcast\", but we're\nlooking less like a bar camp and more like a TED talk.\n\nIt gets worse. Dave ran the query of how many shows were contributed by\neach host over the last 365 days. It shows that 50% of the shows have\nbeen contributed by just 5 hosts. This is not to say that submitting\nmultiple shows is bad, far from it. But it's the difference between\nwanting to submit multiple shows and *needing* to submit multiple shows,\nthat I'm concerned about.\n\nSo a few questions for the list:\n\n- Is this a problem ?\n- If so, how do we fix it ?\n\n*Please* do not derail this discussion about your intentions to record a\nshow. I have a in box full of \"I plan to do a show about this\" or \"I'm\ndefinitely doing a series on that\". More than one are from myself.\nBasically if it's not on the server, it's not a show.\n\nYou can always add a topic to the requested topic page.\nhttps://gitlab.anhonesthost.com/HPR/HPR_Public_Code/blob/master/www/reque\nsted_topics.html\n\n\n\nMore Info: https://hackerpublicradio.org/eps/hpr1851/hpr1851/hpr1851_HPR_Health_2015-09-06.ods\n\nRaw SQL Dump here: \n\n+--------+--------------------------------+-------+\n| hostid | host                           | shows |\n+--------+--------------------------------+-------+\n|    198 | Ahuka                          |    38 |\n|    238 | Jon Kulp                       |    24 |\n|    159 | HPR Volunteers                 |    18 |\n|    225 | Dave Morriss                   |    17 |\n|    131 | FiftyOneFifty                  |    17 |\n|     30 | Ken Fallon                     |    14 |\n|     78 | klaatu                         |     7 |\n|    209 | David Whitman                  |     7 |\n|    280 | semioticrobotic                |     6 |\n|    235 | NYbill                         |     6 |\n|    288 | beni                           |     6 |\n|    195 | Frank Bell                     |     6 |\n|     24 | Lord Drachenblut               |     6 |\n|    287 | corenominal                    |     5 |\n|    282 | Mike Ray                       |     5 |\n|    129 | JWP                            |     4 |\n|    265 | Kevin Wisher                   |     4 |\n|    240 | Steve Bickle                   |     4 |\n|    297 | swift110                       |     4 |\n|    286 | cjm                            |     3 |\n|    285 | 2BFrank                        |     3 |\n|    107 | lostnbronx                     |     3 |\n|    259 | Gabriel Evenfire               |     3 |\n|    215 | Windigo                        |     3 |\n|    296 | Kevie                          |     3 |\n|    300 | Mr. Young                        |     3 |\n|    284 | Steve Smethurst                |     2 |\n|    233 | johanv                         |     2 |\n|    252 | Curtis Adkins (CPrompt^)       |     2 |\n|    294 | daw                            |     2 |\n|    302 | Stilvoid                       |     2 |\n|    197 | garjola                        |     1 |\n|    134 | PipeManMusic                   |     1 |\n|    268 | Andrew Conway                  |     1 |\n|    283 | Inscius                        |     1 |\n|    289 | pyrrhic                        |     1 |\n|    290 | Al                             |     1 |\n|    158 | Various Creative Commons Works |     1 |\n|    109 | Various Hosts                  |     1 |\n|    291 | Rill                           |     1 |\n|    292 | Michal Cieraszynski            |     1 |\n|    270 | Thaj Sara                      |     1 |\n|    293 | Rho`n                          |     1 |\n|    295 | Cibola Jerry                   |     1 |\n|    246 | Beeza                          |     1 |\n|    201 | MrX                            |     1 |\n|    298 | tcuc                           |     1 |\n|    111 | Knightwise                     |     1 |\n|    299 | Fin                            |     1 |\n|    301 | amp                            |     1 |\n|    157 | HPR_AudioBookClub              |     1 |\n|    303 | Alpha32                        |     1 |\n|    306 | GNULinuxRTM                    |     1 |\n|    305 | kurakura                       |     1 |\n|    229 | Charles in NJ                  |     1 |\n|    263 | Tony Pelaez                    |     1 |\n|    307 | cheeto4493                     |     1 |\n|    271 | mirwi                          |     1 |\n|    255 | Matt McGraw (g33kdad)          |     1 |\n|    308 | A Shadowy Figure               |     1 |\n|    309 | folky                          |     1 |\n|    115 | sigflup                        |     1 |\n+--------+--------------------------------+-------+\n\nRegards,\n\nKen Fallon\nhttps://kenfallon.com\nhttps://hackerpublicradio.org/correspondents/0030.html\n

                                                            This podcast is about a little programming exercise I learned in my first programming class. The idea is to generate a random text-based maze and make mouse ('@') search the maze systematically to find the cheese ('V'). If it does so before it runs out of energy (moves) it wins ('$' == happy mouse). Otherwise it starves ('%' == dead mouse).

                                                            \n

                                                            You can find my git repos for the Raspberry PI code including this program at these locations:

                                                            \n\n

                                                            The Mouse-in-a-maze program also requires the catlib library as well which is at:

                                                            \n\n

                                                            You may note that these directories are different from those in my previous RPI episodes. The repositories used to be on gitorious. However since gitlab acquired gitorious, I have migrated the repositories. They currently live on both github and gitlab and I have pushing updates to both for the time being. So I have been waffling about which one will be the ultimate master for these projects. But since, I am doing most all the work on this code myself, it doesn't much matter for the time being.

                                                            \n

                                                            If this is your first time playing with bare metal programming in the RPI you can get more info and tips from HPR episodes 1619, 1630 and 1666. Note that the gitorious links in those episodes are outdated as mentioned above. The github links therein should still be fine though.

                                                            \n

                                                            The mouse code itself is in the apps/mouse0 directory. If you haven't played with this environment before you'll need to do the following:

                                                            \n
                                                              \n
                                                            • Get a compatible ARM toolchain up and running to build for the RPI. I recommend using: https://github.com/dwelch67/build_gcc/blob/master/build_arm

                                                            • You'll need a USB-to-TTL serial cable to hook up to the RPI. I use: https://www.adafruit.com/products/954

                                                            • You'll also need a small SD card to boot from.

                                                            • Follow the steps in catrpi/README.txt to\n

                                                              • create an SD-card with a loader on it.

                                                              • build catlib for the RPI locally (a prereq for building mouse0.bin)
                                                                • \n
                                                              • set up your serial connection to the RPI
                                                                • \n
                                                              • start up a minicom instance to connect to the RPI
                                                                • \n
                                                              • \n
                                                            \n

                                                            Once those prerequisites are taken care of you can:

                                                            • change directory to /path/to/catrpi/apps/mouse0 type make to build

                                                            • serial console to start X-modem reception on the RPI

                                                            • use your terminal program to send the mouse0.bin file via X-modem. In minicom you do this by CTRL-A followed by 's'. You then select 'xmodem' as the protocol and navigate to and select the file mouse0.bin to send.

                                                            \nThe Save WiFi program has been instituted to combat the greatest threat the open source movement has faced from government over regulation. If you have listened to LinuxLUGCast.com, The Linux Link Tech Show, Linux for the Rest od US,or HPR recently, you may already be aware that recent decisions by the FCC have already forced router manufactures to lock down their equipment against the installation of non factory firmware. My guest, Chris Waid, CEO of Think Penguin and a leader in the Save WiFi project, joins me to explain how Linux on the desktop may also become subject to FCC regulation. As manufacturers incorporate more Software Defined Radio into PC's, the FCC may feel it has no choice but to lock down (or lock out), not only open source software, but any software that is not pre vetted and pre certified, even on proprietery OS's.\n

                                                            \nRight now, there is a narrow window where the FCC has invited comment from the public, and Hacker Public Radio invites all our listeners to add their voices against this ill advised course of action.\n

                                                            \nThere is one small saving grace. Kevin Wisher found an Ars Technica article where an unnamed FFC spokesman seems to be saying locking open source firmware out of routers was not the intended consequence (even though Open-WRT was mentioned by name in the updated rules). I think the FCC might prefer manuafacturers avoid incorporating radio hardware that is so easily manipulated:\nhttps://arstechnica.com/information-technology/2015/09/fcc-accused-of-locking-down-wi-fi-routers-but-the-truth-is-a-bit-murkier/\n

                                                            Overview

                                                            \n

                                                            I have a USB printer I bought back in 2005 when I bought a Windows PC for the family. It's an HP PSC 2410 PhotoSmart All-in-One printer. This device is a colour inkjet printer, with a scanner, FAX and card-reading facilities. It has been left unused in a corner for many years, and I recently decided to to see if I could make use of it again, so I cleaned it up and bought some new ink cartridges for it.

                                                            \n

                                                            It is possible to use this printer on Linux using CUPS for the printing and SANE for scanning. I connected it to my Linux desktop for a while to prove that it was usable. However, rather than leaving it connected in this way, I wanted to turn it into a network printer that could be used by the rest of the family. My kids are mostly away at university these days but invariably need to print stuff when they pass through. I searched the Internet and found an article in the Raspberry Pi Geek magazine which helped with this project.

These can be a little bit confusing because they are shared among different LibreOffice modules, so some of the things you see arent really meant for Impress. For example, there are three Title styles, but none of them are meant for putting titles on slides. They are actually meant for putting titles on drawings, such as engineering drawings. If you you wanted to have a slide title but use Text boxes, you should select the Title Only slide layout. The Title would be controlled by the Title Presentation Style.\nFor more go to https://www.ahuka.com/?page_id=1250\n

Bad part of this design is that it does not accommodate the case that I have on my Kindle, so to use the stand with the Kindle I'll have to remove the case. The next photo shows my son's nook color sitting sideways on it. I might try to modify the design so that it will accommodate the Kindle with its case and also prop it up a bit more vertically. Still, this was a really fun experiment with my first 3d printout.

                                                            The second Glasgow Podcrawl took place on the 10th of July 2015. The participants were:

                                                            The event started at 6pm in the State Bar on Holland Street, moved on to the Bon Accord, the Inn Deep and finally to the Three Judges.

I think that it is becoming more common these days for people to own more than one computer and set them up in a network. And with cheap computers like Raspberry Pi it is really easy to get started. In this tutorial I want to discuss how you can set up such a server for your experiments in ssh. I encourage you to do this even though I dont intend this series to focus on server administration. The idea is that by practising these these techniques behind a good firewall you can get some familiarity with them before you get out on the Internet where it matters. For most Linux users, at least, installing and setting up a server is really simple, and you can do it minutes.\nFor more go to https://www.zwilnik.com/?page_id=847 \n

                                                            Hacker Public Radio (HPR) is an Internet Radio show (podcast) that releases shows every weekday Monday through Friday. HPR has a long lineage going back to Radio FreeK America, Binary Revolution Radio & Infonomicon, and it is a direct continuation of Twatech radio. Please listen to StankDawg's \"Introduction to HPR\" for more information.

                                                            What differentiates HPR from other podcasts is that the shows are produced by the community - fellow listeners like you. There is no restrictions on how long the show can be, nor on the topic you can cover as long as they \"are of interest to Hackers\". If you want to see what topics have been covered so far just have a look at our Archive. We also allow for a series of shows so that host(s) can go into more detail on a topic.

                                                            Hi. This is "JustMe". I've been in & out of computing since the late 70s. I'm currently running the latest version of Linux Mint LMDE Mate on this Intel Core2 Q8300 CPU running @ 2.50GHz, on an ASRock motherboard with 8G of memory. Storage is provided by a 120Gb Samsung 850 EVO SSD for the OS and a Western Digital WD20 2T HD as home & swap. Video is provided by nVidia. My monitor is an LG E2441 wide screen. I built this box a few years ago and haven't seen a need to modernize it beyond upgrading the OS because it suits my purposes well. Although I'm seriously contemplating switch my desk top to XFCE because Mate is still too buggy.

                                                            \n

                                                            'nught about me. Let's get on to the subject at hand.

                                                            \n

                                                            I just finished listening to the HPR Community News for September 2015 episode 1871 a couple of days ago. I listened to the two volunteer hosts talking about coffee, coffee preparation and how hard it was to get water to the correct temperature for that optimal cup of coffee. I'd like to ask the two of them a couple of questions before I continue elucidating on this topic.

                                                            \n

                                                            The first question is, can you blind taste test the difference between Nescafé Instant and a cup of, let's say, Starbucks brewed coffee? (a blind taste test is where someone prepares cups of coffee without you knowing which cup has which coffee.) Also notice, I didn't say cappuccino or latte. I said, good ol' fashioned brewed coffee, drunk black.

                                                            \n

                                                            Don't be ashamed if you can't because many people don't have the taste buds for it. But if you can't, I'd say forget making your own and stay with the crappy, Nescafé instant. You'll save yourself a lot of time, money.

                                                            \n

                                                            On the other hand, if you can taste the difference, and you live in the San Francisco area of California, then I'd like to ask another question. Can you taste the difference between Starbucks and Pete's Brewed coffee?

                                                            \n

                                                            If you can, then I propose one more question. Can you taste the difference between a cup of coffee made with Columbian beans and one made with Brazilian beans or Ethiopian beans or Costa Rica Beans?

                                                            \n

                                                            If you can answer yes to all of these questions, then I'd say you should take the time to learn how to make a proper cup of coffee. You will be rewarded a thousand times over with each cup.

                                                            \n

                                                            Now, providing you have answered all in the affirmative or you're just interested in listening to the rest of this podcast, let's digress no further and proceed to the heart of the matter.

                                                            \n

                                                            Making a cup of good coffee, just like making a bottle of good wine or a good omelet, takes understanding of the basics and practice in preparation.

                                                            \n

                                                            The basics of coffee making are simple: Freshly roasted whole beans, a good grinder & proper grind for the type of coffee preparation method, water, water temperature, and brew time.

                                                            \n

                                                            I'm not going to go into a step-by-step dissertation on each brewing method. Suffice it to say, you can take the time for that later. I'll only discuss the essentials here.

                                                            \n

                                                            Let me dally a moment longer. Do you drink wine or beer? When you do or if you do, do you add ice to it? Do you want watered down beer or wine? NO!!! Then why in the hell would you add milk or sugar to your coffee?????? 'nough said on that subject.

                                                            \n

                                                            Let's proceed:

                                                            \n
                                                              \n

                                                            1. By freshly roasted whole beans, I mean just that. Whole beans that have been roasted in the past couple of days. NOT two, three, four, five or more months ago. Beans lose their flavor, go stale, with time. Just like day-old bread. Ground beans lose their flavor even faster, so use only whole beans and grind them as you need them just before brewing. In addition, to maintain their freshness, keep whole beans in an air-tight bag or container, out of direct sunlight and in a cool, dry place (NOT refrigerated). Beans hate time, temperature, sunlight, and air.

                                                              \n

                                                              Another side note here. How much ground coffee per cup? General rule of thumb - 10 grams of ground coffee per 6 ounces of water. The average American cup/mug holds 8-14 ounces of water. So adjust the amount of ground coffee accordingly - experiment. Keep all the other factors the same and only vary the quantity of ground coffee until you get that "just right" cup. But, of course, if you like Nescafé instant, you'll like stale coffee beans and add extra just for fun.

                                                              2. \n

                                                            2. Grinder. A good grinder is imperative. The greatest cost is going to be the grinder. Not all grinders are equal, nor do they grind beans equally well. So don't be afraid to spend good money for a good grinder. Look for a conical or burr grinder. No damn blade grinders. Blade grinders are for spices and grinding dog food. And I don't mean Kitchen Aid or Sunbeam or Cuisinart or Mr. Coffee or such. Look for brand names like Mazzer, Rancilio, Gaggia, Bunn, Macap, or Baratza. Spend good money now, it'll save you money and ensure years of good service.

                                                              \n

                                                              Note that each brewing method needs a different "grind" - coarseness/fineness. Experiment. Keep all the other factors the same and only vary the grind until you get that "just right" cup. But, of course, if you like Nescafé instant, don't worry about the grind.

                                                              \n

                                                              Another side note here. If you answered yes to all of the above questions, I'll guarantee that if I were to prepare two cups of coffee where all of the factors are the same except for the grinder (one cheap & one quality), that you would most definitely swear that different beans were used to make each cup. No Joke. That's the difference a good grinder makes. It, more than any other factor, will change the flavor of your coffee. And you'll more likely than not be missing out on a great cup and be constantly plagued with shit coffee if you cheap out.

                                                              \n

                                                              I can personally attest to this fact. I cheaped out in the beginning. Then I spent the money to buy a great grinder. My first sip of my first cup using the great grinder knocked my socks off. Night and day! I discovered the great taste of coffee that a great grinder provides. So don't cheap out. But, of course, if you like Nescafé instant, you'll like the cheap blade grinder. Or, hell, do it caveman style, just use a hammer to smash the beans.

                                                              3. \n

                                                            3. Water. Mountain spring water is a MUST. The minerals in it help extract the delicate flavors of the coffee giving it a much more fuller, richer flavor. Distilled water leaves coffee tasting flat and lifeless. But, of course, if you like Nescafé instant, you'll like distilled water.

                                                              4. \n

                                                            4. Water temp. Yes. Water temp makes a difference. It's like the difference between scalding milk and burning milk. Coffee's delicate flavors require a temp between 195-200 degrees F or 90-94 degrees C. Too cold, no flavor extraction - flat coffee. Too hot and the oils are extruded - bitter coffee.

                                                              \n

                                                              First bring water to a rolling boil. This airiates the water. Once the water comes to a full boil, remove from the heat. Wait 30-40 seconds then pour into or over your freshly ground coffee beans and stir. For an even more accurate temp reading, use a thermometer. If you make espresso, the espresso maker will take care of the temp, provided you bought a GOOD espresso maker and not a cheap Cuisinart or the likes thereof. But, of course, if you like Nescafé instant, use boiling hot water.

                                                              5. \n

                                                            5. Brew time. Each brewing method's brew time varies (French Press, espresso, pour over, drip, Aero Press, etc.). As little as 30 seconds (espresso) to between three to four minutes for the others is needed. So, experiment. Keep all the other factors the same and only vary the brew time until you get that "just right" cup. But, of course, if you like Nescafé instant, let it steep for 10 minutes.

                                                              6. \n
                                                            \n

                                                            Does all of this seem like a lot of time and bother just for a cup of coffee? Hell, yes!! But didn't it seem like a lot of time and bother to make that first perfect omelet? And wasn't it worth it, once you got the hang of it. It was no fuss at all. It's just like putting your pants on or brushing your teeth. You no longer have to think about it. You just do it.

                                                            \n

                                                            And once you get the hang of it, the timing and flow to making that "Just right" cup of coffee, you'll be able to enjoy a perfect cup every time without breaking a sweat or furrowing a brow.

                                                            \n

                                                            So, here's to ya. Enjoy. And maybe next time we'll look at blending beans to create a euphoric cacophany of mouth flavors.

                                                            \n

                                                            This episode was made out of respect and admiration for the HPR contributers mentioned throughout the show.

                                                            I barely have a clue of what I am doing. And there are mistakes all over the place in this episode. It's just something I wanted to through out there to change things up a little, and pay homage to those I admire, and with a little luck, inspire others to use their creativity to record an episode of their own.

                                                            Depending on the feedback to this episode, I can either follow the theme I started with this show, or do a more traditional HPR episode with a no frills walk through of the process of hacking the T-02 to work as advertised. So let me know what you prefer.

                                                            I give a brief introduction to who I am, and where I live.

                                                            A comparison between my Nexus 7 and my Olympus DM-3 recorder, both with and without the lapel mic. https://media.thelovebug.org/u/thelovebug/m/lapel-microphone-comparisons/

                                                            "If you can hear it, it's good enough."

                                                            What would happen if Alex slipped and rolled down the hill.
                                                            Alex gives a quick introduction to himself.
                                                            He's also the slowest human in history.

                                                            I did run this episode through Auphonic, which didn't do a bad job in the slightest.
                                                            Settings used: Adaptive Leveler, Filtering, Noise and hum reduction set to Auto.
                                                            According to the processing results, hum reduction wasn't needed.

                                                            \n

                                                            It would appear as though I've promised Ken 5 new shows - no pressure, eh.

                                                            \nMosquitoes are responsible for the spread of some of the most deadly and costly diseases, with more than half the world's population living in areas where they are routinely exposed to disease carrying mosquitoes. One of the most deadly diseases that they transmit is malaria, that kills over 600,000 people every year. The Royal Botanic Gardens Kew will equip villagers in rural Indonesia with wearable acoustic sensors to detect the sound of mosquitoes. Each species has its own wing beat allowing the research team to record the occurrence of different species, as well as daily readings of critical environmental conditions. Combined with detailed vegetation maps, this will be able to track disease-bearing mosquitoes. Over the next three years, Kew Gardens will work with Oxford University to turn this project into a reality, creating a downloadable smartphone app and a range of wearable acoustic detectors. This novel technology will be trialled in 150 rural households in Indonesia with the aim of preventing and managing outbreaks of mosquito-borne disease. This prototype technology has the potential ultimately to be rolled out in every region of the world where mosquito-borne diseases pose a threat to life.

This was developed by Microsoft, but has spread to the free software world as well. What it means is that you can use data from two different programs together, and changes made in place are automatically reflected in the other place. A great example comes with spreadsheets, since you create them in a spreadsheet program like Calc, but you might want to take a table created there and put it into a slide to display. \nFor more go to https://www.ahuka.com/?page_id=1275\n

I recorded this in an afternoon when no one else was around except the furry kids and the neighbors outside. I've had the idea for this episode for a while, but having never recorded before didn't really know when/where/how to do it until just now.

Now, technically a server is just the machine you are connecting to, and there is no reason in principle that it could not be another desktop, a laptop, or even a telephone if it has the appropriate software. and in the previous tutorial we showed how you can easily install and set up an ssh server on your home network using another computer or a Raspberry Pi so that you can experiment with these commands. The model really reduces to you as the client, and the other machine as the server. As with all Internet connections there are standards and protocols involved. The original Telnet communicated over TCP through port 23. Because SSH was conceived as a replacement, it used the same TCP protocols, and was assigned the adjacent port number of 22. \nFor more go to https://www.zwilnik.com/?page_id=726 \n

                                                            Hello, HPR. I am OnlyHalfTheTime, the Reluctant Windows Admin. I am a Linux user at home and at heart. I run VPSs on Digital Ocean, host websites all in Linux, mostly Ubuntu. By day, however, I work for an Managed Services Provider which deals with all Windows boxes.

                                                            \n

                                                            Today, I would like to talk about some tips and tricks I have come across while being forced to make the best out of a Windows environment. Being a Linux user, I find that many functions are more quickly completed if you drop to a Command Line Interface. This holds true for many Windows functions as well.

                                                            \n

                                                            First, let's establish the kind of environment you will need.

                                                            \n

                                                            Unfortunately, there is no sudo command built in to Windows. What we will need to do is run a command prompt as an administrator. On Windows 7, you can accomplish this by clicking the start menu, typing cmd, then rightclicking the command prompt program and choosing 'run as administrator'. In Windows 8 and 10, you can right click the start menu directly and click Command Prompt Admin.

                                                            \n

                                                            This is almost the equivalent to running as root. You can affect almost anything except some system protected files. No rm -rf /* for you! The windows user most like root would be SYSTEM. Running a command prompt as SYSTEM is possible to accomplish a few ways, but is very very rarely needed. I can make another podcast about that later, but it is out-of-scope here.

                                                            \n

                                                            Lets get into our first example: User creation is so much easier at the Windows command line. For example, I want to add a local user to a system with administrative rights. From an admin command prompt, I type:

                                                            \n
                                                            net user john hunter2  /add
                                                            \n

                                                            this creates the user john with the password hunter2. Then I type:

                                                            \n
                                                            net localgroup administrators john /add
                                                            \n

                                                            This adds john to the local group administrators. This group has admin rights on this local machine. Say john abuses this privilege and needs to have his permissions revoked.

                                                            \n
                                                            net localgroup administrators john /delete
                                                            \n

                                                            This is much easier than going to the control panel, searching for users, adding a user, defining a password, choosing to make it an admin user. For me at least.

                                                            \n

                                                            Another thing the net command is used for is restarting services. Does that sounds silly to you? I agree! Regardless, let say you want to restart the print spooler on a troubled workstation. You could open a run prompt by hitting Windowskey+R and type "services.msc". This opens up the services window where you can find the service "print spooler" and right click it to restart. or you could just type:

                                                            \n
                                                            net stop spooler\nnet start spooler
                                                            \n

                                                            This is easier to script as well, in case a user is always having trouble printing. Provide a simple batch file (the equivalent of a shell script) to resolve and get on with your day.

                                                            \n

                                                            Affecting files can be a pain in Windows as the paths tend to be esoteric and alien to a Linux user. For example. Let's say I want to copy file foo.bar in the openVPN programs folder to my desktop. I could type:

                                                            \n
                                                            copy "C:\\Program Files (x86)\\OpenVPN Technologies\\OpenVPN Client\\etc\\profile\\foo.bar" "C:\\Users\\john\\desktop\\foo.bar"
                                                            \n

                                                            Gotta remember those doublequotes since Windows has spaces AND parentheses in the full path. Wow. Even with tab completion, that's a lot of work. I have a better solution if you have access to the GUI. Find the file you wish to copy and drag and drop it into the command window. Windows will enter the full path into the prompt. If the files does not already exist where you want it you can't drag it into the prompt. There are variables that can speed up this process. It may not be as elegant and simple as ~, but Windows does have a variable for the local user's home directory. You can type:

                                                            \n
                                                            %HOMEPATH%\\desktop\\foo.bar
                                                            \n

                                                            But you are saying, wait OnlyHalfTheTime, this doesn't save me any time or keystrokes! This is true in this specific case, but in scripting, it becomes important to use variables instead of full paths. I may not have Windows installed in the "C" drive for example. Also, some are real time-savers. if you use %APPDATA% for example, it maps to C:{username}.

                                                            \n

                                                            Now, let's say I am going to be doing a lot of work in a specific directory. I could keep entering the full path, but come on, no one likes that guy. I could open a command prompt and cd or change directory, just like in Linux. or I could find the directory in the file explorer and right click in the folder while holding down shift. This gives you and extra option in the context menu named 'open command windows here' which does exactly that. You will get a command window opened with the working directory set as the folder in which you right clicked.

                                                            \n

                                                            Hopefully some of these methods will help folks like me: Windows admin by day, Linux enthusiast by night. This is OnlyHalfTheTime, the Reluctant Windows Admin, signing off.

Apt spelunking is the act of aimlessly searching\n\tthrough your distribution's software repositories, and picking out the gems\n\tthat you find. I call it apt spelunking because I use Debian, which uses the\n\tapt packaging format.\n

                                                            \n\tThe package tvtime is a simple one, but it does what it does very well. tvtime\n\tinterfaces with a TV tuner - specialized hardware that allows your computer to\n\tprocess analog television signals, via coaxial or RCA video cables. If you have\n\tthis hardware, usually an expansion card or USB peripheral, tvtime allows you to\n\tuse your computer as an analog television.\n

                                                            \n

It has filters that can help smooth out the image a\n\tbit, but it's still an analog video.\n

                                                            \n

                                                            \n\ttvtime is video only, so you need to use something else to handle the audio of\n\twhatever you are hooking up. Often this is done by the hardware tv tuner\n\tsomehow; my PCI card tuner has a 3.5mm jack that offloads any sound received\n\tover the coaxial wire, and I patch that into my sound card. RCA cables have\n\tseparate wires for audio, and I plug those into my sound card via a converter\n\tcable.\n

It's helped me to defeat Eternal Darkness, an old GameCube game that\n\tis still worth a look, and it's allowed me to digitize old VHS tapes we have\n\tlying around. More on that in another episode.\n

                                                            \n\tTo use phatch, you assemble a set of operations (phatch refers to these as\n\t\"actions\") in an ordered \"action list\". I'll use my gallery thumbnail action\n\tlist as an example.\n

                                                            \n

                                                            \n\tThere are only two actions in my thumbnail action list: \"fit\", and \"save\". Each\n\taction has a set of predefined parameters and options that let you tweak what\n\thappens to your files. The \"fit\" action resizes an image without goofing up the\n\taspect ratio. You give it a box to fit the image in, and it fits it fully into\n\tthat box and cuts off any extra edges. The most important parameters for this\n\taction are canvas width, and canvas height - which tells phatch how big the box\n\tis. The save action has parameters that let you set which image format to use,\n\twhich folder to save to, and even what to name the file. For my thumbnails, I\n\thave it use the original filename, and append a \"_t\".\n

                                                            \n

                                                            \n

                                                            \n\tFirst of all, let's start with the practical. You can set the size of the image\n\txstarfish generates, by either using the -g flag and manually setting the\n\tgeometry with a pixel width and/or height, or you can use the -s flag and set a\n\tgeneral size like \"small\", \"large\", or \"full\". If you use \"full\", xstarfish\n\tautomatically generates a full wallpaper for your display.\n

                                                            \n

                                                            \n\tSince xstarfish generates randomness (which is often CPU intensive) and uses\n\tthat to generate random filters (which can be hard on your CPU) and can be set\n\tto do it periodically (which, depending on frequency, could keep your CPU busy),\n\tthis utility can be a resource hog. I have two monitors, each running 1280x1024\n\tresolution, and when I set it to generate a new background every 10 seconds...\n\twell, it didn't. It just maxed out one of my CPU cores, and spit out a\n\tbackground every once and a while. Cutting it down to only generate a single\n\tmonitor-sized image every 60 seconds made things much more reasonable.\n

                                                            \n

                                                            \n\tThe second, more pertinent issue with xstarfish is that it randomly picks colors\n\tand patterns. It is exceptionally random about it. Imagine for a moment that you\n\tneeded to paint a room, and you wanted to pick random colors and patterns for a\n\troom in your house. You would begin by blindfolding a friend and pushing them\n\tinto the paint isle at your nearest hardware store. Whatever three buckets of\n\tpaint they bump into first, well, that's your color palette. What do you mean\n\tyou don't like orange, sea foam and gunmetal grey? \n

                                                            \n\tThen, you take those paint cans and proceed to tie one to your ceiling fan, one\n\tto your eight-year-old child and swing the third around your head at a 35 degree\n\tangle. Fairly quickly, you'll have your own xstarfish-inspired decor.\n

                                                            \n

                                                            \n\tWith all of the potentially awful things that can happen, I really do like\n\txstarfish. It's not something I keep running all the time, and a lot of the\n\toptions remind me of early 90s Encino Man fashion and school photo backdrops\n\twith lasers. But sometimes the patterns are actually quite pleasing, and if I\n\tkeep the tile size small, it reminds me of 90s web design.\n

                                                            \n\tThat concludes the second installment of apt spelunking. Please don't let me\n\ttake all the glory; take a tour through your package manager, whatever distro\n\tyou use, and tell us about some cool stuff you find!\n

                                                            Many of the tedious repetitive processes I had to do on image files and audio files are done by bash scripts that are launched by voice commands, as demonstrated in the YouTube video above. The processes I'm talking about are things like renaming files according to my filenaming conventions, putting the files in the right place, resizing images, converting images to different formats, optimizing them for file size, converting audio from MIDI to ogg and mp3, and reducing audio from two channels to one in order to reduce file size. Below are the main tools I use for this, apart from the Linux bash shell itself. If you're interested in actually seeing the scripts I wrote to perform the magic, I am happy to share. Just drop me an email.

So now it is time to take a look at Tables. You have options here, such as embedding a table from Calc or Writer, and there are times when you need that degree of power. But most of the time you can do what you need inside of Impress using its own functionality. As we saw last time with Charts, you can just click the button in the middle of a new slide and insert a Table that way, but that may not always be feasible, so you have the alternative option of going to the Insert menu and selecting Table. \nFor more go to https://www.ahuka.com/?page_id=1285\n

                                                              \n
                                                            • Password You authenticate to the server by typing in your password. This is easy because you can generally remember your password, and it means you can easily login from any computer with that knowledge. This is still the most common authentication mechanism for SSH. It is also the least secure.\n
                                                              • \n
                                                            • Public Key This is much more secure. It involves the creation of a key pair, of course. It is possible to use a key pair generated by PGP or GPG in the most current versions (version 2.0.13 introduced support for this). But there is a long established method using the Unix program ssh-keygen. This is very similar to generating a key pair as we discussed earlier. You run the program ssh-keygen, harvest some entropy, generate a passphrase to protect it, and so on.\n
                                                              • \n
                                                            \n\n

                                                            \n

                                                            In Episode 1900, Ahuka advised you not to expose the ssh service to the Internet on the default port 22, there we agree. This is called "Security Through Obscurity". Whenever possible, server functions exposed to the Internet should be on non-default port numbers (the exception being HTTP on a public web server). I disagree however, in Ahuka's method of changing the port. He said you should change the port on the server itself:

                                                            \n

                                                            From https://www.cyberciti.biz/tips/setup-ssh-to-run-on-a-non-standard-port.html

                                                            \n

                                                            Open /etc/ssh/sshd_config file and look for line Port 22 and change line to Port 2222. Restart sshd server. systemctl restart sshd

                                                            \n

                                                            Sshd is running on a non-standard port, connection attempts to the system will fail. You need to connect using following command:

                                                            \n
                                                            $ ssh -p 2222 user@your-ip OR $ ssh -p 2222 user@you.homenetwork.org
                                                            \n

                                                            This could make sense if you manage a business or school network, where you have numerous users within your network with whom you share varying levels of trust. Still, I don't think anyone who can brute force your shh logon or shared keys would be stymied by a simple change of ports. But Ahuka also mentioned home networks, and I think we would rather keep things simple. I would humbly suggest keep ssh servers set to port 22 internally, and using a technology called "port forwarding" available on most consumer routers. Port forwarding is simply an administrator configured table that redirects incoming traffic on one IP port to a specific internal IP address and IP port on your internal network. In fact, unless you have only one PC connected directly to you ISP with no router or firewall, you will still need to setup port forwarding to tell the router which machine on your network the for which incoming communication is intended.

                                                            \n

                                                            In other words, let's say you've enabled ssh on port 40001 of a machine with an internal address of 192.168.1.5. You try to login remotely via ssh on port 40001 using the external IP assigned to you by your ISP (which is taken from a range assigned to them by the IANA). The external IP of your router should be displayed on your router's status page, or you could type "what is my IP" into Google. Instead of an IP in the range 192.168.x.y, like you are probably using internally, your external address will be in the Class A or B range, for instance 73.149.12.124.

                                                            \n

                                                            So let's say you have ssh server running on port 40001 on a machine with IP adddress 192.168.1.5 on your home network. Your server has an external address of 73.149.12.124. You are at work or on vaction or whatever and you want to ssh into that machine on your home network, i.e,

                                                            \n
                                                            ssh -p 40001 you@73.149.12.124
                                                            \n

                                                            Unless the router itself supports ssh server (entirely possible with third party Linux based firmwares like Open-WRT and DD-WRT), if you haven't configured port fowarding, the router won't have any idea what to do with an incoming request on port 40001. You need to set up your port forwarding table in your router (don't worry, it's all point and click). IP forwarding may be under Advanced, in the menus, or Security, or Firewall, or a combination of the above.

                                                            \n

                                                            You will be asked to enter the external port number (in our example, 40001), TCP or UDP or both (in our case, ssh is both, so you may have to create two separate entries), the internal IP address (in our example 192.168.1.5) and the internal port number (if you changed it internally as Ahuka recommended, in our example 40001, but, and this is the whole point of this podcast, you are going to have to set up port forwarding anyway, so why change the port number locally in the first place? If the terms TCP (Transport Control Protocol) and UDP (User Data Protocol) are unfamiliar to you, the difference can easily be explained. Using TCP, the computer transmitting data stops every few packets (I think the default is three, but don't hold me to it) until it gets an acknowledgment from the receiver that the packets were successfully received, then the sender continues. With UDP, the sender blurts out the whole transmission without caring whether the receiver go it or not.

                                                            \n

                                                            Wikipedia has a great article on official and unofficial standardized port numbers. Once you get into five digits, conflicts to already assigned ports are rare, but it's still best to consult the Wiki. The higher numbers are generally not officially assigned, some particular software product is just "squatting" on the number. In fact, using the port number for a technology you are certain will never be used on your network may further obfuscate the service for which you are actually using it. You may think port 40001 is surely high enough to be free of conflict, but the Wiki says 40000 is used by "SafetyNET p Real-time Industrial Ethernet protocol".

                                                            \n

                                                            Another advantage of port redirection is you could use a different external port number with every host on your network, i.e., 40001 redirects to you server, 40002 redirects to your desktop, 40003 redirects to the old laptop in the kid's room, etc. Personally, I'd only have port redirection into a single machine that is connected persistently (like a server), and the ssh from it into other hosts on the network (yes, this would be a connection of at least three nested shells). You can even run graphical programs over ssh with the -X argument, but I'm leaving that on for later discussion. Of course, we will loose that functionality when we move from x-server to Wayland, so if you need a GUI you may have to investigate technologies like VNC or VPN.

                                                            \n

                                                            Of course, everything depends on having a static IP locally on the ssh server (either set on host itself or manual assignment of IP on the router, if possible). You either need a static external address on the WAN (i.e., external address as seen from the Internet) side or employ a domain forwarding service. Also keep in mind, once we get Ivp6, everything above goes out the window.

                                                            I Found a Flashlight

                                                            A couple of weeks ago on the way to work I found a flashlight (or a \"torch,\" for those folks across the pond). It was rolling around on the street getting run over by cars and seemingly not suffering any damage as result. As soon as it was safe, I walked out into the street and grabbed it and took it with me. A little poking around online showed me that this was no ordinary device, but a police-grade flashlight.

                                                            \n\n\n\n

                                                            I contacted the Lafayette Police Department to find out what kind of flashlights they used and whether anyone had reported one missing. Ordinarily when I find something I don't worry about this, but I discovered that this thing cost quite a lot of money—around $125 on Amazon with a retail price of $225—and if a police officer had lost it I certainly didn't want him going into his own pocket to replace it if I could just give it back to him. The police department wrote back to me saying, yes, this was the kind of flashlight that they issued to their officers but no one was missing one. I also asked the University Police and they said they don't normally issue flashlights but that sometimes officers bought their own and no one had reported missing one.

                                                            \n\n

                                                            After seeing the amazing build quality and absolutely unbelievable light quality this thing produced, I decided to keep it and so I had to buy a charger to recharge the battery. This cost about $28 and now I'm the proud owner of a Streamlight SL-20L flashlight. This is truly one of the greatest tools I've ever had. Listen to the show to hear me sing its praises!

I wonder how well some of the commentary present in this book will resonate in the future. The story is good enough I have no doubt that it will still be a good read, but I'm not sure if it might loose a bit.

                                                            \nThere are a few feeds that are not handled properly by Bashpodder, namely, the TED Talks podcast feed and the NPR digest show called the TED Radio Hour.\n

                                                            \n

                                                            \nThe URLs for the audio files have a number of additional fields at the end of the string after the media file name, and Bashpodder picks up the last field as if it were the media file name for the show. So every TED Radio Hour episode is called \"510298\". If you download more than one episode at a time, only the last episode to be saved will survive. Each new file clobbers the last one, because they all get the same filename.\n

                                                            I have been contributing shows to Hacker Public Radio since 2012. In those far off days (!) we sent everything in via FTP, and had to name the files with a combination of our host id, our name, the slot number and the title. The show notes had to contain a chunk of metadata in a defined format to signal all of the various attributes of the show. I found myself making numerous mistakes with this naming and metadata formatting and so started designing and writing some tools to protect myself from my own errors.

                                                            \n

                                                            I started developing a Bash script in mid-2013 which I called hpr_talk. I used Bash since I thought I might be able to make something with a small footprint that I could share, which might be useful to others. The script grew and grew and became increasingly complex and I found I needed to add other scripts to the toolkit and to resort to Perl and various Perl modules to perform some actions.

                                                            \n

                                                            Then in 2014 Ken changed the upload procedure to what it is now. This is a much better design and does away with the need to name files in odd ways and add metadata to them. However, this left my toolkit a bit high and dry, so I shelved the plans to release it.

                                                            \n

                                                            Since then I have been enhancing the hpr_talk toolkit, adding features that I found useful and removing bugs, until the present time. Now it is probably far too complex and idiosyncratic to be of direct use to others, and is rather too personalised to my needs to be easily shared. Nevertheless, it is available on GitLab and I am going to describe it here in case it (or the methods used) might be of interest to anyone.

                                                            \n

                                                            I have written out a moderately long set of notes about this subject and these are available by clicking this link.

                                                            \n

                                                            I had to record this in two parts. In the second part there was a constant background hum which I tried to remove. My removal process was not particularly successful I'm afraid, so it cuts in and out. I'm still learning how to do this sort of thing in Audacity!

                                                            I'm moving into my new office at work, and among many things I had to move are file boxes full of old class notes from graduate school. The academic hoarder in me doesn't want to recycle them—I might need these things again! I'm scanning.

                                                            \n\n

                                                            I've inherited an excellent scanner/copier with a feeder that lets you scan stacks of pages with one click. This works great for single-sided documents, but most of my handwritten notes are double-sided. I scan one side, then turn the stack over and scan the other side, and I end up with two PDFs for a single stack of pages—one with the front pages and the other with back pages in reverse order. The difficulty is to collate the pages of those two files so that the front and back sides appear in a single PDF in the correct order. Sounds like a job for a shell script!

                                                            \n\n

                                                            The script takes two CLI arguments. The first argument is the PDF containing front pages, and the second is the PDF of the back pages.

                                                            \n\n

                                                            The first job is take the backsides and reverse the page order, because they were scanned in last-page-to-first. This is very easy with pdftk:

                                                            \n\n
                                                            pdftk back.pdf cat end-1 output backfix.pdf
                                                            \n\n

                                                            Now that the pages are all in the correct order it's time to collate them. We're going to use the burst function of the PDF toolkit to explode each of the two PDFs into separate pages. After that, we recombine the separate pages in the correct order. The trick is finding a way to do this efficiently. In concept, it's not hard to collate pages in whatever order you want after they've been burst. You simply keep giving pdftk CLI arguments for all of the files you want to combine and then output them as a single file. However, if you have 40 or 50 pages, it's extremely tedious to provide that many CLI args one at a time. This must be automated!

                                                            \n\n

                                                            The way I figured out how to do this was to ensure that the burst command would output files that would appear in the correct order automatically when using the ls command inside the working directory. The burst command automatically numbers the output files, but you can specify certain filename formatting parameters if you want to. I chose a format that would begin the filename with the numerical page count in at least three digits with leading zeros (001, 002, etc), followed by an underscore and either the word \"front\" for the front pages or \"reverse\" for the back pages.

                                                            \n\n

                                                            So here are the burst commands:

                                                            \n\n
                                                            \npdftk front.pdf burst output %03d_front.pdf\npdftk backfix.pdf burst output %03d_reverse.pdf\n
                                                            \n\n

                                                            At this point a bunch of new files appear, looking something like this:

                                                            \n\n
                                                            \n001_front.pdf\n001_reverse.pdf\n002_front.pdf\n002_reverse.pdf\n003_front.pdf\n003_reverse.pdf\n...\n
                                                            \n\n

                                                            Notice how the front and back pages all appear in the correct order? Now, instead of typing in the filename for every page, we can use the output of the ls command, filtering out any files not beginning with numbers.

                                                            \n\n
                                                            pdftk $(ls |grep ^[0-9]) cat output collated.pdf
                                                            \n\n

                                                            And it's done. The entire script loks like this:

                                                            \n\n

                                                            \n

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampeling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            • Noise Floor: -50db

                                                            • Attack Time: 0.2sec

                                                            • Decay Time: 1.0 sec

                                                            • \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.
                                                              • \n
                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extreemly effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too agressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            \nThis is a topic Ken Fallon has been wanting someone to do for some time, but I didn't want to talk about sshfs until the groundwork for ssh in general was laid. Fortunately, other hosts have recently covered the basics of ssh, so I don't have to record a series of episodes just to get to sshfs.\n

                                                            \n

                                                            \nFrom the sshfs man page: SSHFS (Secure SHell FileSystem) is a file system for Linux (and other operating systems with a FUSE implementation, such as Mac OS X or FreeBSD) capable of operating on files on a remote computer using just a secure shell login on the remote computer. On the local computer where the SSHFS is mounted, the implementation makes use of the FUSE (Filesystem in Userspace) kernel module. The practical effect of this is that the end user can seamlessly interact with remote files being securely served over SSH just as if they were local files on his/her computer. On the remote computer the SFTP subsystem of SSH is used.\n

                                                            \n

                                                            \nIn short, sshfs offers a dead simple way of mounting remote network volumes from another system on at a specified mount point on your local host, with encrypted data communications. It's perfect for at hoc connections on mobile computers or more permanent links. This is tutorial is going to be about how I use sshfs, rather than covering every conceivable option. I really think my experience will cover the vast majority of use cases without making things complicated, besides, I don't like to discuss options I haven't used personally.\n

                                                            \n

                                                            \nThere are other ways to mount remote storage, most noteably SAMBA, but unless you are trying to connect to a Windows share, sshfs is far less trouble to set up, escpecially since most distros come with ssh-server already installed.\n

                                                            \n

                                                            \nThe first thing to do when preparing to use sshfs is to create a mountpoint on your local computer. For most purposes, you should create a folder inside your home folder. You should plan to leave this folder empty, because sshfs won't mount inside a folder that already has files in it. If I was configuring sshfs on a machine that had multiple users, I might set up a mount point under /media, then put symlinks in every user's home folder.\n

                                                            \n

                                                            \nThe sshfs command syntax reminds me of many of the other extended commands based ssh, like scp. The basic format is:\nsshfs username@<remote_host>: mountpoint\n

                                                            \n

                                                            \nTo put things in a better perspective, I'll use my situation as an example. My home server is on 192.168.2.153. If you have a hostname set up,you can use that instead of an IP. For the sake of arguement, my mountpoint for network storage is /home/fifty/storage . So, I can mount the storage folder on my server using:\n

                                                            \n

                                                            \nsshfs fifty@192.168.2.153: /home/fifty/storage\n

                                                            \n

                                                            \nBy default, your whole home directory on the remote system will be mounted at your mountpoint. You may have noticed the colon after the IP address, it is a necessary part of the syntax. Lets say you don't wish to mount your whole remote home folder, perhaps just the subdirectory containing shared storage. In my case, my server is an Raspberry Pi 2 with a 5Tb external USB drive which is mounted under /home/fifty/storage . Say, I only want to mount my shared storage, not everything in my home folder, I modify my command to be:\n

                                                            \n

                                                            \nsshfs fifty@192.168.2.153:storage /home/fifty/storage\n .or.\nsshfs fifty@192.168.2.153:/home/fifty/storage /home/fifty/storage\n

                                                            \n

                                                            \nExcept that generally doesn't work for me, and I'll come to that presently. The 5Tb USB drive on the server isn't actually mounted in my home folder, it automounts under /media. The directory /home/fifty/storage on the server is actually a symlink to the actual mountpoint under /media. To make sshfs follow symlinks, you need to add the option '-o follow_symlinks', so now my sshfs command looks like:\n

                                                            \n

                                                            \nsshfs fifty@192.168.2.153: /home/fifty/storage -o follow_symlinks\n

                                                            \n

                                                            \nYou may have noticed, the \"-o\" switch comes at end the end of the command. Usually switches come right after the command, and before the arguements. \n

                                                            \n

                                                            \nThis will allow sshfs to navigate symlinks, but I've discovered not all distros are comfortable using a symlink as the top levelfolder in a sshfs connection. For example, in Debian Wheezy, I could do:\n

                                                            \n

                                                            \nsshfs fifty@192.168.2.153:storage /home/fifty/storage -o follow_symlinks\n

                                                            \n

                                                            \nOther distros, Ubuntu, Mint, Fedora so far don't like to connect to a symlink at the top level. For those distros, I need to use:\n

                                                            \n

                                                            \nsshfs fifty@192.168.2.153: /home/fifty/storage -o follow_symlinks\n

                                                            \n

                                                            \nand walk my way down to storage.\n

                                                            \n

                                                            \nOther related options and commands I haven't used but you may be interested in include -p , for Port. Lets say the remote server you want to mount is not on your local network, but a server out on the Internet, it probably won't be on the default ssh port. Syntax in this case might look like:\n

                                                            \n

                                                            \nsshfs -p 1022 fifty@142.168.2.153:storage /home/fifty/storage -o follow_symlinks\n

                                                            \n

                                                            \nReading the man page, I also find \"-o allow_root\" which is described as \"allow access to root\" . I would expect, combined with a root login, this would mount all of the storage on the remote system, not just a user's home directory, but without direct expertience, Iwouldn't care to speculate further. \n

                                                            \n

                                                            \nThe mount can be broken with 'fusermount -u <mountpoint>'. \n

                                                            \n

                                                            \nAt this point, I could explain to you how to modify /etc/fstab to automatically mount a sshfs partition. The trouble is, /etc/fstab is processed for local storage before any network connections are made. Unless you want to modify the order in which services are enabled, no remote storage will ever be available when /etc/fstab is processed. It makes far more sense to encapsulate your sshfs command inside a script file and either have it autoloaded with your desktop manager or manually loaded when needed from a terminal.\n

                                                            \n

                                                            \nOne thing to watch out for, is saving files to the mountpoint when the remote storage is not actually mounted, i.e., you save to a default path under a mountpoint you expect to be mounted and is not, so all the sudden you have files in a folder that is supposed to be empty. To remount the remote storage, you have to delete/move the paths created at your designated mountpoint, to leave a pristeen, empty folder again.\n

                                                            Quassel is a centralized IRC hub that allows several client computers to appear as only one connection to the IRC server, i.e. Freenode. About the same time NYBill posted Episode 1869 "IRSSI Connectbot", I was wondering how to merge all my simultaneous IRC connections from multiple hosts to the same channel on the same server into one connection. I did a search on "GUI front end IRSSI" and came up with Quassel instead. I think NYBill and I are trying to solve pretty much the same problem. I'm not trying to say my solution is better than NYBill's, I'm just saying it's the one that appeals the most to me.

                                                            \n

                                                            Problem: IRC servers (or at least Freenode) do not allow simultaneous connection from multiple hosts using the same user identifier. I.E., if I was logged in on the PC on my desk via XChat as FiftyOneFifty, if at the same time I was connected to IRC via a PC on the kitchen counter, I would have to use "Kitchen5150" as my identifier. If I was away from home, but left a computer connected to IRC back home, if I connected againover Android I'd have to be Andro5150. I could adopt all these other personas as aliases, which protected them from theft and allowed me to still have admin rights on channels where I was admin depite using a different login. These multiple versions of me running in IRC inevitably lead to confusion about which was the "real" FiftyOneFifty, a situation which MrJackson is all too familiar with, I'm sure.

When moving between local hosts, disconnect from the current screen or tmux session, ssh into the server from the new host, and reconnect to the session running irssi. The irssi ncurses interface may not be as pretty or easy for some users as a GUI, but I understand it is quite functional.

Connect multiple simultaneous clients to the core via quassel-client. All clients share the same IRC display at the same time, all the while transparent to the server (i.e. Freenode), which only sees the one login from the host running quassel-core.

                                                            5. Set up Port Forwarding on your router. I suggest you use an external port other than the default 4242 (Security Through Obscurity, see my Port Forwarding episode).

                                                              6. \n
                                                            \n

                                                            All the configuration is done by the client!

                                                            \n

                                                            B. Install quassel-client

                                                            \n
                                                              \n

                                                            1. All you need to connect is an IP address and the external port number. The first account you create will be master and the only account with the ability to create other users. In other words, if someone else had your server's IP address and the port Quassel-core is listening on, they could beat you to establishing a master account and controll Quassel on your server.

                                                              2. \n

                                                            2. Once you have established a connection to a core and set your password, you can set up the default IRC servers and channels. It's a GUI interface, so I'm not going to walk you through the menus and various inputs. I only had success setting up one IRC server (Freenode) in the initial setup on the first client (as you connect addition clients, you will find your channels are already configured), and then only if I avoided ssl connections. Channels are entered into a list in the normal way (#channel_1, #channel_2, etc), but once you connect to a server, /join commands become persistant. I added a second IRC server, tllts, once I finished the initial setup.

                                                              3. \n
                                                            \n

                                                            The user interface is similar to XChat,but not quite as polished.

                                                            \n
                                                              \n

                                                            1. You get popup notifications when someone uses your handle in a chat, but scrolling back to find it, rather than being in a different color, it shows up in a garish reverse text. Easier to spot, but not as eligant.

                                                              2. \n

                                                            2. No way to search back posts for your handle or anything else.

                                                              3. \n

                                                            3. Links posted by others only have "copy this link function", not "open this link in default browser"

                                                              4. \n

                                                            4. I don't seem to have spellchecking enabled in my IRC client. I discovered spell checkwas central in Linux, rather than every app having it's own version (i.e. I assume FireFox under Windows has it's own spellcheck libraries as Office has it's own library). I wonder if I installed hunspell on the Quassel core server, if I would suddenly get spellcheck ( https://hackerpublicradio.org/eps.php?id=1356 ).

                                                              5. \n
                                                            \n

                                                            There is a perfectly adequate Android client for Quassel. Like AndChat, YAAIC, and the others, it seems to drop the connection unless you actively participating, but since the server is persistent, you never miss out on what was said while your client was disconnected.

                                                            \n

                                                            The last time I was awy for the weekend, I shut off all my PC's and network devices. One drawback of a local Quassel server would be my LAN and Quassel Core server would need to be up even when I was away from home.

                                                            \n

                                                            Migrating Quassel from my local server to the cloud: About a week after I'd set up Quassel, a buddy anounced he had secured a Digital Ocean Droplet ($5 a month, limited storage, limited bandwidth). He was open to letting his friends use the service, as long as their requirements were low impact. I jumped on the oppurtunity to move my quassel-core over to the "cloud". Remember the five and a half steps to setting up quassel-core under Arch? According to my friend who manages the Digital Ocean Droplet running Ubuntu Server, it was pretty much "sudo aptitude install quassel-core". Once the core was running I then configured the new core from one of the clients (i.e., pointed quassel-client to a new IP and port number, then created an account and password). Since I was on a new server, I had to set up connections my IRC channels again. After that, every client I migrated to the new core inherited those channels from the server. A week or so after moving the core to the cloud, I came home to find my Internet had been down for a few hours. Cycling the power on the ISPs tranceiver and my router fixed my Internet connection, and since Digital Ocean had experienced no interruption, I was still able to scroll back to the five hours of IRC I missed.

                                                            \n

                                                            Frank got a lot of comments about his episode and there seemed to be an interest in the subject. I have been interested in Chinese, Indonesian and other Far Eastern cookery styles for some time, and do a lot of cooking, so I thought I'd record a show about one of the recipes I use.

                                                            My son visits around once a week and eats dinner with me. I offered to cook him my version of Chow Mein, which since he is vegetarian, needed to use no meat. This is my description of the recipe I used.

                                                            I loosely based this version of Chow Mein on Ken Hom's recipe in his book Chinese Cookery, page 226. This is from his 1984 BBC TV series, which I watched. I also learnt many of my preparation techniques from Ken Hom's books and TV shows.

                                                            • Install alternate launcher, such as KUAL, the Kindle Unified Application Launcher. This is a framework that allows developers to create menu items that will launch applications on a jailbroken Kindle.

                                                            \n

                                                            As we saw in the last episode 1903 there are seven types of expansion applied to the command line in the following order:

                                                            \n
                                                              \n
                                                            • Brace expansion (we looked at this subject in episode 1884)
                                                              • \n
                                                            • Tilde expansion (seen in episode 1903)
                                                              • \n
                                                            • Parameter and variable expansion (this was covered in episode 1648)
                                                              • \n
                                                            • Command substitution (seen in episode 1903)
                                                              • \n
                                                            • Arithmetic expansion
                                                              • \n
                                                            • Word splitting
                                                              • \n
                                                            • Pathname expansion
                                                              • \n
                                                            \n

                                                            There is also another, process substitution, which occurs after arithmetic expansion on systems that can implement it.

                                                            \n

                                                            We will look at one more of these expansion types in this episode but since there is a lot to cover, we'll continue in a later episode.

                                                            • Turned the stereo tracks to mono

                                                            • Used a Noise Gate plug-in to reduce background noise (after "training" it on some silence)

                                                            • Performed a Truncate Silence pass to reduce the length of pauses

                                                            • Applied a small amount of amplification

                                                            Let me know if this had any positive or negative effects on the end product.

                                                            \n

                                                            The first option is fix_tags and was written by our own Dave Morriss.

                                                            Next up is mediainfo which provides a lot of information on media files.

                                                            The last option is to use ffprobe from the ffmpeg team.

While my parents were visiting during the holidays, my dad taught me, the wife, and the kids how to turn pens on his mini lathe. We made a few mechanical pencils, a pen and I also made a giant workshop pencil. Click on the image below to look at the gallery of photos on Flickr.

                                                            1. First go to this site: https://garmin.openstreetmap.nl/\n
                                                              2. \n
                                                            2. Then select your map type\n
                                                              3. \n
                                                            3. Select and download the predefined area or tiles you want. You can download it directly or have the web page build it for you by entering your email address and pushing the button BUILD MY MAP.\n
                                                              \na) If you choose the email option then you get an email that the map is being built and another (later on) that the map is ready.\n
                                                              4. \n
                                                            4. Unzip the file\n
                                                              5. \n
                                                            5. Rename the downloaded map to gmapsupp.img \n
                                                              6. \n
                                                            6. Save your old map (that's on your device) entitled to a different name and then backup\n
                                                              7. \n
                                                            7. Put the map you unzipped and renamed in its place and make sure it is renamed to 'gmapsupp.img' (omit the single quotes I have used in these show notes)\n
                                                              8. \n
                                                            8. Use your device and thank OSM\n
                                                              9. \n

                                                            \nOSM maps have more data for my area than the Garmin supplied map World Wide maps are available. See where Peter64, Ken Fallon or even 5150 lives. It's cheaper than buying a commercial map Trails, points and other improvements I put on OSM can be on my map I like the OSM concept and community.\n

DRLM is a Centralized Management Open Source solution for small-to-large Disaster Recovery implementations using ReaR. Is an easy-to-use software to manage your growing ReaR infrastructure. Is written in the bash language (like ReaR) and offers all needed tools to efficiently manage your GNU/Linux disaster recovery backups, reducing Disaster Recovery management costs. ReaR is great solution, but when we’re dealing with hundreds of systems, could be complex to manage well all ReaR deployments.\n
                                                            \nWith DRLM you can, easily and centrally, deploy and manage ReaR installations for all your GNU/Linux systems in your DataCenter(s). DRLM is able to manage all required services (TFTP, DHCP-PXE, NFS, …) with no need of manual services configuration. Only with few easy commands, the users will be able to create, modify and delete ReaR clients and networks, providing an easy way to boot and recover your GNU/Linux systems through network with ReaR. Furthermore DRLM acts as a central scheduling system for all ReaR installations. Is able to start rear backups remotely and store the rescue-boot/backup in DR images easily managed by DRLM.\n
                                                            \nYou can easily enable or disable the last or any previous backups to restore any client with a single command line. Currently DRLM supports PXE and NETFS(nfs) OUTPUT/BACKUP methods of ReaR, but the Development of DRLM non stops here, we are working on new 2.0 version with new features to improve performance, usability and more ReaR methods, in order to become, together with ReaR, the reference when talking about Disaster Recovery of GNU/Linux systems.\n

Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture. The main goal of the ReactOS® project is to provide an operating system which is binary compatible with Windows. This will allow your Windows® applications and drivers to run as they would on your Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows® would find using ReactOS straightforward. The ultimate goal of ReactOS® is to allow you to use it as alternative to Windows® without the need to change software you are used to.\n

This is really the flagship product, closely followed by EFL itself. The window manager is a lean, fast, modular and very extensible window manager for X11 and Linux.

This covers launching applications, managing their windows and doing other system tasks like suspending, reboots, managing files etc.\n

At the core of these principles is the promise of better-quality, highly-reliable and secure software that gives you greater flexibility at zero cost and no end-user lock-in. LibreOffice works natively with the Open Document Format, but also brings you support for by far the most file types for office-documents. It comes with support for over 80 languages and with a whole amount of other unique features to work with your texts, spreadsheets, presentations, drawings and data.\n

Applications range from controlling computers / machines, biofeedback and Quantified Self. At first sight, the current generation of commercial devices seem to be decent in their functionality, and various use cases are suggested. However, neurophysiological signal quality, as well as limitations of software and hardware hackability are among the greatest issues and hurdles towards advancement in user experience. This is why we started to work on Brain-Duino, an open-source brainwave amplifier shield for the Arduino and other microcontrollers. Brain-Duino is a high quality, low noise and affordable EEG / BCI for hackers, makers, researchers, artists and other enthusiasts. \n

                                                            I have been looking for a tool that will graphically and programmatically track identifiers as they pass through systems. I could have done this in Inkscape after following the excellent tutorials on https://screencasters.heathenx.org/, however I also wanted to be able to describe the relationships programmatically.

                                                            \n

                                                            This got me to thinking about graphical query builders for databases. The idea is to show each system as a table block and then draw lines between them to show how \"Field_X\" in \"System_A\" will map to \"Field_Y\" in \"System_B\". Many of the proprietary and some free database solutions allow this type of view. However I also want to easily package the entire thing up, so that someone else could access it without needing to pay for or install any specialized software. That limited the choice of database to SQLite, which is small, supported on many platforms and is released into the Public Domain.\n

                                                            SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is the most widely deployed database in the world with more applications than we can count, including several high-profile projects.
                                                            \nPlease follow the instructions on the SQLite site for information on how you can install it on your system. For me on Fedora it's simple to install via dnf/yum. You might also want to install some GUI managers if that's your thing.\n
                                                            dnf install sqlite sqlitebrowser sqliteman\n
                                                            \n

                                                            I created a small database for demonstration purposes, consisting of two tables and one field in each.

                                                            \n

                                                            Next step is to download SQLeo Visual Query Builder which has support for a graphical query builder.\n

                                                            A powerful SQL tool to transform or reverse complex queries (generated by OBIEE, Microstrategy, Cognos, Hyperion, Pentaho ...) into diagrams to ease visualization and analysis. A graphical query builder that permits to create complex SQL queries easily. The GUI with multi-connections supports virtually all JDBC drivers, including ODBC bridge, Oracle, MySQL, PostgreSQL, Firebird, HSQLDB, H2, CsvJdbc, SQLite. And top of that, everything is open-source!
                                                            \n

                                                            SQLeo is a Java Tool and there is a limited version available on the web site which is limited to 3 tables per graph and 100 rows. Now as the program is released under the GPLv2.0, you could download the code and remove the restrictions. You can also support the project to the tune of €10 and you will get the full version ready to rock.

                                                            One slightly confusing thing, and the reason for this post, is that I could not find support for SQLite listed in the list of databases to connect to. A quick search on the support forum and I found the question \"Connection to SQLite DB\". I found the answer a bit cryptic until I read the manual related to JDBC Drivers, which told me how to add the sqlite library.

                                                            \n

                                                            SQLeo uses a standard Java sqlite library that is released under the Apache Software License, Version 2.0. You can download it from the SQLite JDBC MVNRepository and save it into the same directory as SQLeo.

                                                            \nToday, I am going to be talking about a more advanced usage of the terminal in linux. This basic tutorial assumes that you have a basic knowledge of getting to the terminal, and installing software, so we can skip that, and make my job easier.\n

                                                            \n

                                                            \nFirst, you have software that you may want to run, and keep running, even if we disconnect, or even if we walk to another machine. Classically, there was 'screen' for this, but times change, and needs advance. My current favorite is byobu, a wrapper for the screen or tmux terminal multiplexers, tmux by default, now, which is a change since featured on episode 770 of HPR.\n

                                                            \n

                                                            \nTo run byobu, simply type it's name at the terminal, and watch it's magic. When we say it is a wrapper, this is in double context. It encapsulates the tmux or screen binary in script, and it provides some useful enhancements to the already awesome capabilities of a basic multiplexer, including a nice bar at the bottom, detailing the system stats, configurable to whatever stats you need to display.\n

                                                            \n

                                                            \nA screen multiplexer is an application that allows the running of multiple terminals, and their applications, within a single remote or local window, allowing you to change tasks with relative ease, similar to a window manager in X, but with no mouse needed.\n

                                                            \n

                                                            \nFor a basic test, go ahead and hit F2, and you will get a second terminal, the textual task tray at the bottom indicating your current and available terminals. F3 and F4 allow you to cycle between tasks, and F2 spawns additional.\n

                                                            \n

                                                            \nFor those following along, go ahead and hit F6, you will drop back to a shell, with byobu running everything in the background, and you can exit the terminal, or run whatever else you need to, outside of byobu's control. Use the byobu command again to reconnect, note that your session has remained open, and all terminal sessions are available for you to peruse. Also note that you can open byobu again, as the same user, both remotely and locally, and keep all of your terminals going, even on multiple systems and screens, at the same time. You can even share the session with others, assuming their ability to login, and cross code, or monitor usage of their session, for educational purposes, or group coding.\n

                                                            \nA popular and useful feature of terminal windows is the ability to maintain a scroll back buffer, and using a multiplexer, ostensibly, destroys this ability on the graphical side, assuming you are using it in a graphical environment, keeping the text for itself. Fear not, good hacker, for the simple application of F7 will activate scroll back mode, and allow your cursor (or arrow) and page keys to scroll up and down the text buffer. Enter settles you back to the end, allowing quick access to whatever just happened in that specific task windows while you were away.\n

                                                            \nThis story begins at the beginning of 2010.  I was broke at the time so I was trying to find a free operating system. I needed something I could run on my PC’s at home. I had searched on the Internet, but found nothing useful for a long time. But one day  I was at Barnes and Noble and I saw a magazine for Linux. (While I had heard of linux before I never thought of it as something I would ever be able to use.) When I asked people who I knew were computer professionals, I was told it was for people that were experts, and difficult to use. I never heard anything positive about it. I am so amazed that I hadn’t came across it sooner.

                                                            \n

                                                            When I read the magazine I became exposed to Ubuntu 9.10.  Karmic Koala. It sounded so good, as if it was exactly what I was looking for. As a result, I got very excited took it home, and to my surprise had such an easy time installing it to my PC that I decided to run it along with Windows XP as a dual boot system. All I did was put the live CD in the drive and the instructions were step by step you would have to be pretty slow to not get how to set things up.

                                                            \n

                                                            Since then I have been very satisfied with Ubuntu in general and I have been able to check out later versions of it such as 10.04 (Maverick Meerkat) and 10.10 Lucid Lynx. I am looking forward to 11.04 Natty Narwhal for how it integrates multi-touch even more than 10.04.  This experience just goes to show once again how I  manage to find the coolest stuff by accident.

                                                            In late 2013 I noticed the local Edinburgh Hacklab were offering soldering courses building a BlinkStick. I offered to sign my son Tim up to the next course since he wanted to learn to solder. He couldn't afford the time at that point, but we agreed to buy some BlinkSticks to build at home.

                                                            The version we bought and built was the v1.0 release, since that and the BlinkStick Pro were all that was available.

                                                            \nRichard Matthew Stallman (born March 16, 1953), often known by his initials, rms,[1] is a software freedom activist and computer programmer. He campaigns for software to be distributed in a manner such that its users receive the freedoms to use, study, distribute and modify that software. Software that ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation, developed the GNU Compiler Collection and GNU Emacs, and wrote the GNU General Public License.\n
                                                            \nStallman launched the GNU Project in September 1983 to create a Unix-like computer operating system composed entirely of free software. With this, he also launched the free software movement. He has been the GNU project's lead architect and organizer, and developed a number of pieces of widely used GNU software including, among others, the GNU Compiler Collection, the GNU Debugger and the GNU Emacs text editor. In October 1985 he founded the Free Software Foundation.\n
                                                            \nStallman pioneered the concept of copyleft, which uses the principles of copyright law to preserve the right to use, modify and distribute free software, and is the main author of free software licenses which describe those terms, most notably the GNU General Public License (GPL), the most widely used free software license.\n
                                                            \nIn 1989 he co-founded the League for Programming Freedom. Since the mid-1990s, Stallman has spent most of his time advocating for free software, as well as campaigning against software patents, digital rights management, and other legal and technical systems which he sees as taking away users' freedoms, including software license agreements, non-disclosure agreements, activation keys, dongles, copy restriction, proprietary formats and binary executables without source code.\n
                                                            \nAs of 2014, he has received fifteen honorary doctorates and professorships.\n\n

                                                            \n

                                                            sed is an editor which expects to read a stream of text, apply some action to the text and send it to another stream. It filters and transforms the text along the way according to instructions provided to it. These instructions are referred to as a sed script.

                                                            \n

                                                            The name \"sed\" comes from Stream Editor, and sed was developed from 1973 to 1974 as a Unix utility by Lee E. McMahon of Bell Labs. GNU sed added several new features including better documentation, though most of it is only available on the command line through the info command. The full manual is of course available on the web.

                                                            Steel-Cut oats are amazingly good—delicious and nutritious—but they're kind of a pain to cook because they're so hard and require so much simmering. It can take up to 30 minutes to cook them on the stove top and you have to stir constantly to make sure they don't boil over or stick to the pan. I tried doing them in a rice maker and in the microwave, neither of which turned out well. Then I tried the slow cooker and found that this is the perfect way to make steel-cut oats exactly right every time with hardly any effort.

The water and oats should be combined in a 4 to 1 ratio. When I make this using American measurements, I used 1 Cup water for each ¼ cup of oats. In the metric system this is about 240 ml water for each 40 grams of oats.

                                                            Linux.conf.au, is the name and website of my favourite conference. Known by insiders as simply lca, it is an annual technical conference, focusing on Linux and Open Source technologies. LCA is a roaming conference, going to a different city of Australia and New Zealand every year. I've helped organise the two lca's in my home town of Brisbane, Queensland, and it was in fact the first of these that introduced me to lca. This year lca was held in Geelong, down in the state of Victoria and it counts as my fifteenth linux.conf.au. Clearly this conference has become quite a big part of my life and it's probably a mature thing to stand back and have a look at why.

                                                            \n

                                                            lca is a technical conference, it's not a sales oriented conference, as an engineer having non-salesy, technical content makes me feel at home. For the most part, the paper committee only accept talks from people directly working on a project, so the speakers we select know their topic. lca is explicitly an open source conference, and mostly a low level conference.

                                                            \n

                                                            lca is a week long conference, so I often add some extra time on the end to make a holiday out of it. A fair percentage of our attendees are from overseas, and it makes sense for them to do the same. I have taken the train to a Perth (Western Australia) lca, that's the Indian Pacific train, a three day trip from one side of the country to the other. I've done a day trip on a train in New Zealand, from Auckland to Wellington. I've done a couple of motorcycle trips, down to Ballarat and Geelong (both cities in the state of Victoria). Those two tours are roughly a 3600km (or 2200 mile) round trips taking three to four days each way.

                                                            \n

                                                            I've done a motorcycle tour of Tasmania (an island state of Australia) after a Tasmanian lca. Next year, the conference is back in Tasmania for the Hobart lca, I'm planning on doing a week long hike of about 85kms (50 odd miles) before the conference along the South Coast Track.

                                                            \n

                                                            There are a bunch of people that I only get to see at lca, from year to year, sadly some of these come from my own home town. Keeping these connections strong is an important part of lca for me.

                                                            \n

                                                            Every year, the parent organisation of lca, Linux Australia holds their Annual General Meeting during lca. I've been an Ordinary committee member on the Linux Australia council a couple of times now. This year I didn't get enough votes, which means I have more time to devote to other things, like HPR recordings :)

                                                            \n

                                                            Registration for lca normally starts Sunday afternoon, there's often a beginners guide to the conference. After fifteen years, I don't think I've ever attended one, but I should probably help lead it next year..

                                                            \n

                                                            It's very common for lca to choose a charity to raise money for. For many years this meant a loud, long, often raucous auction. In recent years we've had a raffle over the full length of the conference. We've helped many worthy charities over the years, the one that comes to mind was the 'Save the Tasmanian Devils' fund, for which we raised a substantial amount of money, something around forty thousand dollars, partly based on the auction prize of changing the linux's kernel logo from Tux to Tuz, the lca mascot for that year. Tuz is a Tasmanian devil wearing a costume Penguin beak to cover over his case of the Devil Facial Tumour Disease, a communicable cancer, that is threatening their existence. This was also the conference where Linus shaved bDale's beard off to raise money for the charity.

                                                            \n

                                                            We often hold lca at a university, and we often use student dormitories as accommodation. If we're lucky, this means that a large percentage of attendees can meet up in common areas of the accommodation at the end of the day and continue the conference long into the night. A particularly memorable lca on this front, somewhere in New Zealand, I forget which city, had a whole level of a student accommodation centre set aside as a common area, so a large percentage of the conference were able to fit and continue the conference late into the evening.

                                                            \n

                                                            The first two days of the conference are generally reserved for miniconferences, or miniconfs as we refer to them. These miniconfs go for one or two days and are organised around a particular topic, and separately to the main conference. The miniconfs change every year, but commonly include miniconfs focused on the kernel (this is primarily attended by kernel coders), hardware (based around ardunio, raspi, and this year espy), multimedia and music, sysadmin, OpenRadio, Open Source in Government. A highlight from the second Brisbane lca was the rocketry miniconf, where 25 odd rockets were put together and later launched. We've been blessed over the years to have miniconfs working to improve and enlarge our community, including LinuxChix, Haecksen and the Community Leadership Summits.

                                                            \n

                                                            After the miniconf days are done, the conference proper begins. These days start off with a keynote, have four or more streams of talks during the day, with longer tutorials running for half the day.

                                                            \n

                                                            My favourite keynote from this year was Genevieve Bell, from Intel. From previous years, Tim Berners Lee, Eben Moglen and Kathy Sierra have left long term marks. These are people who have fundamentally created the world I live and work in now, their contributions cannot be understated.

                                                            \n

                                                            There are a bunch of talks from every year that change the way I think about something, or the way I work. This year, I reckon the Record/Replay talk will probably change the way I debug programs. RR is a Mozilla tool, you run the buggy program under rr, which records exactly what the system calls the program runs, what state effects the program has, then you run that recording under the standard debugger, gdb. Typically with gdb you can only step forwards into the program, but with rr you can actually step back in time as well!

                                                            \n

                                                            A hardware talk that really caught my attention this year was the Linux Microwave, a regular microwave with a set of scales and a thermal imaging camera added, so that whenever you heat/warm/defrost something, the microwave will never ever burn/under/over cook the food!

                                                            \n

                                                            The other bit of hardware that I feel warrants a mention was the large loom that one of our venues, the National Wool Museum was built around. It is programmed by a large bunch of punch cards! There's always local attractions that add something to the conference.

                                                            \n

                                                            During the week, ad-hoc groups form around common interests, we call these Birds-of-feather sessions. I usually end up attending the Emacs BoF. A recurring BoF is the jobs BoF, where employers and hopeful employees come together.

                                                            \n

                                                            I don't tend to attend too many tutorials myself. A number of years back I ran a tutorial on Antlr, a recursive descent parser toolkit.

                                                            \n

                                                            There are a number of social events that happen most years, the conference dinner, the speakers dinner, and the professionals session. These events target the different audiences at the conference. A favourite spin on this was during a Melbourne lca where diners were given food and drink tokens to use around a market, rather than a traditional sit down dinner. The speakers dinner is a smaller, more private thank you to the speakers, many of whom have flown in from overseas. The professionals session tends to be the most varied, as it tends not be a full meal, but just a place where folks can meet, greet and swap business cards.

                                                            \n

                                                            I can't say it's always been a bed of roses, I've had a couple of hospital trips over the years, one for myself where, along with almost half of the conference, I came down with the dreaded noro-virus, a gastro bug that is prevalent on cruise ships. During another lca when I was chaperoning another attendee to hospital I figured my lca was over, but then I struck up a conversation with our ambulance driver, and it turned out he'd been working on pdp-11s during his uni days!

                                                            The other awful lca experience I have to mention was the flooding that occurred just one week prior to our second Brisbane lca. All of our venues were affected, some were destroyed completely. We had to shift our main venue about 5kms up the road, hire buses, find new caterers at the last minute, a whole world of pain.

                                                            For many years now, most of our talks have been recorded, using our own recording system. All of these videos are up on the Linux Australia server and youtube. This means that weeks, months after the conference is finished, I find myself watching a recording that someone has recommended, and it takes me back to that one week in every year where the world makes sense to me.

                                                            This half-hour-long episode describes the complete process for turning an old, limited thin-client terminal (an HP T5740) - and incidentally just about any other kind of hardware - into a simple automatic media-playing kiosk-style device, running VLC on a hand-made minimalist Arch Linux installation. I've tried to describe the procedure I came up with in enough detail that anyone with a little bit of Linux experience can hopefully follow and potentially replicate the whole thing, but not so much detail that it gets horrifically tedious. Some of the extra details I glossed over in the audio are here in the show notes if you want them.

                                                            This episode will mostly be of interest to people with a little bit of Linux experience, but may hopefully be interesting to a few others. Mac and Windows partisans take note: before you start giggling about how \"complicated\" it is to set up Linux as you listen to what I describe here, I will reiterate that I chose to do the install \"by hand\" like this, and I assure you a more typical Linux install is quite a bit simpler (having just spent several months brutally installing Windows systems on innocent computers, getting and ordinary Linux installation finished is not only easier but faster. (\"Windows is getting ready to start to prepare to configure updates. Please wait 5 hours and don't turn off your computer...\") So there.

                                                            I actually have also tried the \"web browser kiosk\" thing with the browser loading up a particular web page on start. It actually works just fine, except that the Windows DHCP server seems to be kind of slow, and if I just let the system start without checking the browser initially just shows an \"internet no work\" sort of message. I got around this nicely by adding a couple of steps to .xinitrc before starting the web browser. First, I created a graphic to use as an X background that just has text that indicates that it's waiting for the network to come up. Then, I put a loop in .xinitrc that checks for a hostname on the internet to see if it resolves to an IP yet, which would tell me the internet had come up. I didn't want to have to install any specific additional software utilities or, ideally, to have to do any special parsing. It turns out that you can just use \"getent ahosts4 google.com\" (or other internet hostname) as a test for this - it will return nothing if the name doesn't resolve, so you only need to test if the response is not a blank. I used \"sleep 1\" to pause one second between tries. Once the resolution returns something, I had xsetbg change the background graphic to a more appropriate default and continue starting the browser, the VNC server, etc.

                                                            Find the line starting GRUB_CMDLINE_LINUX_DEFAULT and add intel_idle.max_cstate=1 before quiet splash\".

                                                            \n

                                                            Then ctrl-o, ctrl-x to save & exit, and type: sudo update-grub to update Grub.

                                                            \n

                                                            Remove the USB stick and reboot, and you should now have a self-sufficient booting system.

                                                            Conflict between sdhci-acpi and brcmfmac

                                                            Due to some conflict between sdhci-acpi and brcmfmac (https://bugzilla.kernel.org/show_bug.cgi?id=88061), a parameter has to be changed for the sdhci-acpi driver. There are several ways to do this, but a quick fix is to add this line in /etc/sysfs.conf (make sure you have the package sysfsutils installed), this way the option is passed before the brcmfmac driver is loaded :

                                                            \n
                                                            # Disable SDHCI-ACPI for Wireless, otherwise WLAN doesn't work\nbus/platform/drivers/sdhci-acpi/INT33BB:00/power/control = on
                                                            \n

                                                            microSD Card Reader

                                                            \n

                                                            Create a file /etc/modprobe.d/sdhci.conf with the following content:

                                                            \n
                                                            # Adjustment to make micro SD card reader work\noptions sdhci debug_quirks=0x8000
                                                            \n

                                                            Then run

                                                            \n
                                                            update-initramfs -u -k all
                                                            \n

                                                            After a reboot the card reader should be working.

The job is to replace the serpentine belt, idler pulley, and belt tensioner in the hope of getting rid of a very annoying loud chirping sound that was coming from my engine. Even after cutting out the long pauses where I was staring at my engine trying to imagine how I was going to get the belt to go in the indicated pattern, this episode still tops out at about one hour. Be warned. There are several sections where you're just kind of listening along to sounds of nature as I work.

                                                            I've been trying to record this particular show for ages but I can never seem to finish it. I find the topic just too interesting. When I start then I get distracted by some other aspect. Every time I try to record it Murphy gets in the way, with lost recordings and broken cards etc. This is the email that prompted this show.

                                                            What are orbits ?

                                                            In physics, an orbit is the gravitationally curved path of an object about a point in space, for example the orbit of a planet about a star or a natural satellite around a planet. Orbits of planets are typically elliptical, and the central mass being orbited is at a focal point of the ellipse.

                                                            Newton's cannonball was a thought experiment Isaac Newton used to hypothesize that the force of gravity was universal, and it was the key force for planetary motion. It appeared in his book A Treatise of the System of the World.

                                                            It is worth noting that orbital rockets are launched vertically at first to lift the rocket above the atmosphere (which causes frictional drag), and then slowly pitch over and finish firing the rocket engine parallel to the atmosphere to achieve orbit speed.

                                                            \n

                                                            Once in orbit, their speed keeps them in orbit above the atmosphere. If e.g., an elliptical orbit dips into dense air, the object will lose speed and re-enter (i.e. fall). Occasionally a space craft will intentionally intercept the atmosphere, in an act commonly referred to as an aerobraking maneuver.

They cross the equator multiple times per day and each time they are at the same anglewith respect to the sun. Satellites on these types of orbits are particularly useful for capturing images of the Earth’s surface or images of the sun

Thus they remain stationary over a single line of longitude. A geostationary satellite will remain in a fixed location as observed from the surface of the earth, allowing a satellite dish to be alligned to it.

The Iridium satellite constellation also uses a polar orbit to provide telecommunications services. The disadvantage to this orbit is that no one spot on the Earth's surface can be sensed continuously from a satellite in a polar orbit.

It was a 58 cm (23 in) diameter polished metal sphere, with four external radio antennae to broadcast radio pulses. It was visible all around the Earth and its radio pulses were detectable. This surprise success precipitated the American Sputnik crisis and triggered the Space Race, a part of the larger Cold War. The launch ushered in new political, military, technological, and scientific developments.

                                                            I attended OggCamp15 in Liverpool at the end of October 2015. As usual I bought some raffle tickets as a contribution to the expenses of the (un-)conference, not paying much attention to the prizes.

                                                            \n

                                                            Actually, the star prize was a laptop donated by Entroware, a significant sponsor of the event, one of the most impressive prizes ever offered at OggCamp. There was quite a lot of excitement about this prize.

                                                            \n

                                                            I attended the drawing of the raffle at the end of proceedings on the Sunday. Dan Lynch (of Linux Outlaws, and a frequent organiser of OggCamp) was in attendance overseeing the selection of the raffle tickets. Various smaller prizes were won and the tension built up as the final drawing approached.

                                                            \n

                                                            Things got very tense when the first number drawn for the laptop was called and nobody responded. Then another draw was made.

                                                            \n

                                                            Imagine my shock and surprise when I realised I had the winning ticket! I had won the star prize in the OggCamp raffle!

                                                            JSON is a popular way of storing data in a key/value type arrangement so that the data can be parsed easily later. For instance, here is a very simple JSON snippet:

                                                            \n
                                                            {\n"name":"tux",\n"health":"23",\n"level":"4"\n}
                                                            \n

                                                            If you are like me, three questions probably spring to your mind:

                                                            \n
                                                              \n

                                                            1. That looks an awful lot like a Python dictionary.

                                                              \n

                                                              Yes, it looks exactly like a Python dictionary. They are shockingly similar. If you are comfortable with Python lists and dictionaries, you will feel right at home with JSON.

                                                              2. \n

                                                            2. I don't feel comfortable with dictionaries, can't I just use a delimited text file?

                                                              \n

                                                              You can, but you will have to write parsers for it yourself. If your data gets very complex, the parsing can get pretty ugly.

                                                              \n

                                                              That is not to say that you should not use a simple delimited text file if that is all that your programme needs. For example, I would not want to open a config file as a user and find that I have to format all my options as valid JSON.

                                                              \n

                                                              Just know that JSON is out there and available, and that the JSON Python module has some little features that make your life easier when dealing with sets of data.

                                                              3. \n

                                                            3. Why not use XML instead?

                                                              \n

                                                              You can. Mostly one should use the most appropriate format for one's project. I'm a big fan of XML, but sometimes JSON makes more sense.

                                                              4. \n
                                                            \n

                                                            I am not going to make this post about teaching the JSON format. If you need clarification on how to structure data into JSON, go through a tutorial on it somewhere; there are several good ones online. Honestly, it's not that complex; you can think of JSON as nested dictionaries.

                                                            \n

                                                            Starting from scratch, let's say that you write a programme that by nature gathers data as it runs. When the user quits, you want to save the data to a file so that when the user resumes the app later, they can load the file back in and pick up where they left off.

                                                            \n

                                                            Storing Data as JSON

                                                            \n

                                                            At its most basic, the JSON data structure is basically the same as a Python dictionary, and in fact the nice thing about JSON is that it can be directly imported into a Python dictionary. Usually, however, you are resorting to JSON because you have somewhat complex data, so in the sample code we will use a dictionary-within-a-dictionary:

                                                            \n
                                                            #!/usr/bin/env python\n\ngame = {'tux': {'health': 23, 'level': 4}, 'beastie': {'health': 13, 'level': 6}}\n# you can always add more to your dictionary\n\ngame['konqi'] = {'health': 18, 'level': 7}
                                                            \n

                                                            That code creates a ditionary called game which stores the player name and a corresponding dictionary of attributes about how the player is doing in the progress of the game. As you can see after the comment, adding new players is simple.

                                                            \n

                                                            Now let's see how to save that data to a save file.

                                                            \n

                                                            That would be your save command. Simple as that, all the structured content of your game dictionary is committed to a file on your hard drive.

                                                            \n

                                                            If you are saving data to JSON, you probably will evenually want to read the data back into Python. For this, Python features the function json.load

                                                            \n
                                                            import json\n\ndosiero = open('dosiero.json')\ngame = json.load(dosiero)\n\nprint game['tux']     # prints {'health': 23, 'level': 4}\nprint game['tux']['health']    # prints 23\nprint game['tux']['level']     # prints 4\n\n# when finished, close the file\n\njson_data.close()
                                                            \n

                                                            As you can see, JSON integrates surprisingly well with Python, so it's a great format when your data fits in with its model.

                                                            XML is a popular way of storing data in a hierarchical arrangement so that the data can be parsed later. For instance, here is a simple XML snippet:

                                                            \n
                                                            <?xml version="1.0"?>\n<book>\n   <chapter id="prologue">\n      <title>\n     The Beginning\n </title>\n   </chapter>\n</book>
                                                            \n

                                                            The nice thing about XML is that it is explicit and strictly structured. The trade-off is that it's pretty verbose, and getting to where you want to go often requires fairly complex navigation.

                                                            \n

                                                            If you do a quick search online for XML parsing in Python, your two most common results are lxml and beautifulsoup. These both work, but using them feels less like opening a dictionary (as with JSON) to look up a definition and more like wandering through a library to gather up all the dictionaries you can possibly find.

                                                            \n

                                                            In JSON, the thought process might be something like:

                                                            \n

                                                            "Go to the first chapter's title and print the contents."

                                                            \n

                                                            With traditional XML tools, it's more like:

                                                            \n

                                                            "Open the book element and gather all instances of titles that fall within those chapters. Then, look into the resulting object and print the contents of the first occurrence."

                                                            \n

                                                            There are at least two libaries that you can install and use to bring some sanity to complex XML structures, one of which is untangle.

                                                            \n

                                                            Untangle

                                                            \n

                                                            With untangle, each element in an XML document gets converted into a class, which you can then probe for information. Makes no sense? well, follow along and it will become clear:

                                                            \n

                                                            First, ingest the XML document. Assuming it's called sample.xml and is located in the current directory:

                                                            \n
                                                            >>> import untangled\n>>> data = untangle.parse('sample.xml')
                                                            \n

                                                            Now our simple XML sample is sitting in RAM, as a Python class. The first element is <book> and all it contains is more elements, so its results are not terribly exciting:

                                                            \n
                                                            >>> data.book\nElement(name = book, attributes = {}, cdata = )
                                                            \n

                                                            As you can see, it does identify itself as "book" (under the name listing) but otherwise, not much to look at. That's OK, we can keep drilling down:

                                                            \n
                                                            >>> data.book.chapter\nElement(name = chapter, attributes = {'id': 'prologue'}, cdata = )
                                                            \n

                                                            Now things get more interesting. The next element identifies itself as "chapter", and reveals that it has an attribute "id" which has a value of "prologue". To continue down this path:

                                                            \n
                                                            >>> data.book.chapter.title\nElement(name = title, attributes = {}, cdata = The Beginning )
                                                            \n

                                                            And now we have a pretty complete picture of our little XML document. We have a breadcrumb trail of where we are in the form of the class we are invoking (data.book.chapter.title) and we have the contents of our current position.

                                                            \n

                                                            Sniping

                                                            \n

                                                            That's very linear; if you know your XML schema (and you usually do, since XML is quite strict) then you can grab values without all the walking. For instance, we know that our chapters have 'id' attributes, so we can ask for exactly that:

                                                            \n
                                                            >>> data.book.chapter['id']\n'prologue'
                                                            \n

                                                            You can also get the contents of elements by looking at the cdata component of the class. Depending on the formatting of your document, untangle may be a little too literal with how it stores contents of elements, so you may want to use .strip() to prettify it:

                                                            \n
                                                            >>> data.book.chapter.title.cdata.strip()\n'The Beginning'
                                                            \n

                                                            Dealing with More Than One Element

                                                            \n

                                                            My example so far is nice and tidy, with only one chapter in the book. Generally you'll be dealing with more data than that. Let's add another chapter to our sample file, and some content to each:

                                                            \n
                                                            <?xml version="1.0"?>\n<book>\n   <chapter id="prologue">\n      <title>\n     The Beginning\n  </title>\n      <para>\n     This is the first paragraph.\n      </para>\n    </chapter>\n\n    <chapter id="end">\n      <title>\n     The Ending\n  </title>\n      <para>\n     Last para of last chapter.\n      </para>\n    </chapter>\n</book>
                                                            \n

                                                            Accessing each chapter is done with index designations, just like with a dict:

                                                            \n
                                                            >>> data.book.chapter[0]\nElement(name = chapter, attributes = {'id': 'prologue'}, cdata = )\n>>> data.book.chapter[1]\nElement(name = chapter, attributes = {'id': 'end'}, cdata = )
                                                            \n

                                                            If there is more than one instance of a tag, you must use a designator or else untangle won't know what to return. For example, if we want to access either the title or para elements within a chapter:

                                                            \n
                                                            >>> data.book.chapter.title\nTraceback (most recent call last):\nFile "<stdin>", line 1, in <module>\nAttributeError: 'list' object has no attribute 'title'
                                                            \n

                                                            Oops. But if we tell it which one to look at:

                                                            \n
                                                            >>> data.book.chapter[0].title.cdata.strip()\n'The Beginning'\n>>> data.book.chapter[1].title.cdata.strip()\n'The Ending'
                                                            \n

                                                            Or you can look at the paragraph instead of the title. The lineage is the same, only instead of looking at the title child, you look at the para child:

                                                            \n
                                                            >>> data.book.chapter[0].para.cdata.strip()\n'This is the first paragraph.'\n>>> data.book.chapter[1].para.cdata.strip()\n'Last para of last chapter.'
                                                            \n

                                                            You can also iterate over items:

                                                            \n
                                                            >>> COUNT = [0,1]\n>>> for TICK in COUNT:\n...     print(data.book.chapter[TICK])\nElement <chapter> with attributes {'id': 'prologue'} and children\n[Element(name = title, attributes = {}, cdata = The Beginning ),\nElement(name = para, attributes = {}, cdata = This is the first paragraph.)]\n\nElement <chapter> with attributes {'id': 'end'} and children\n[Element(name = title, attributes = {}, cdata = The Ending ),\nElement(name = para, attributes = {}, cdata = Last para of last chapter.)]
                                                            \n

                                                            And so on.

                                                            \n

                                                            Easy and Fast

                                                            \n

                                                            I'll admit the data structure of the classes does look odd, and you could probably argue it's not the cleanest and most elegant of all output; it's unnerving to see empty cdata fields or to constantly run into the need to strip() whitespace. However, the ease and speed and intuitiveness of parsing XML with untangle is usually well worth any trade-offs.

                                                            Quick re-cap about XML:

                                                            XML is a way of storing data in a hierarchical arrangement so that the data can be parsed later. It's explicit and strictly structured, so one of its benefits is that it paints a fairly verbose definition of data. Here's an example of some simple XML:

                                                            \n
                                                            <?xml version="1.0"?>\n<book>\n   <chapter id="prologue">\n      <title>\n     The Beginning\n  </title>\n      <para>\n     This is the first paragraph.\n      </para>\n    </chapter>\n\n    <chapter id="end">\n      <title>\n     The Ending\n  </title>\n      <para>\n     Last para of last chapter.\n      </para>\n    </chapter>\n</book>
                                                            \n

                                                            And here's some info about the xmltodict library that makes parsing that a lot easier than the built-in Python tools:

                                                            \n

                                                            Install

                                                            \n

                                                            Install xmltodict manually, or from your repository, or using pip:

                                                            \n
                                                            $ pip install xmltodict
                                                            \n

                                                            or if you need to install it locally:

                                                            \n
                                                            $ pip install --user xmltodict
                                                            \n

                                                            Xmltodict

                                                            \n

                                                            With xmltodict, each element in an XML document gets converted into a dictionary (specifically an OrderedDictionary), which you then treat basically the same as you would JSON (or any Python OrderedDict).

                                                            \n

                                                            First, ingest the XML document. Assuming it's called sample.xml and is located in the current directory:

                                                            \n
                                                            >>> import xmltodict\n>>> with open('sample.xml') as f:\n...     data = xmltodict.parse(f.read())
                                                            \n

                                                            If you're a visual thinker, you might want or need to see the data. You can look at it just by dumping data:

                                                            \n
                                                            >>> data\nOrderedDict([('book', OrderedDict([('chapter',\n[OrderedDict([('@id', 'prologue'),\n('title', 'The Beginning'),\n...and so on...
                                                            \n

                                                            Not terribly pretty to look at. Slightly less ugly is your data set piped through json.dumps:

                                                            \n
                                                            >>> import json\n>>> json.dumps(data)\n'{"book": {"chapter": [{"@id": "prologue",\n"title": "The Beginning", "para": "This is the first paragraph."},\n{"@id": "end", "title": "The Ending",\n"para": "This is the last paragraph of the last chapter."}]\n}}'
                                                            \n

                                                            You can try other feats of pretty printing, if they help:

                                                            \n
                                                            >>> pp = pprint.PrettyPrinter(indent=4)\n>>> pp.pprint(data)\n{ 'book': { 'chapter': [{'@id': 'prologue',\n                         'title': 'The Beginning',\n             'para': 'This is the ...\n                         ...and so on...
                                                            \n

                                                            More often than not, though, you're going to be "walking" the XML tree, looking for specific points of interest. This is fairly easy to do, as long as you remember that syntactically you're dealing with a Python dict, while structurally, inheritance matters.

                                                            \n

                                                            Elements (Tags)

                                                            \n

                                                            Exploring the data element-by-element is very easy. Calling your data set by its root element (in our current example, that would be data['book']) would return the entire data set under the book tag. We'll skip that and drill down to the chapter level:

                                                            \n
                                                            >>> data['book']['chapter']\n[OrderedDict([('@id', 'prologue'), ('title', 'The Beginning'),\n('para', 'This is the first paragraph.')]),\nOrderedDict([('@id', 'end'), ('title', 'The Ending'),\n('para', 'Last paragraph of last chapter.')])]
                                                            \n

                                                            Admittedly, it's still a lot of data to look at, but you can see the structure.

                                                            \n

                                                            Since we have two chapters, we can enumerate which chapter to select, if we want. To see the zeroeth chapter:

                                                            \n
                                                            >>> data['book']['chapter'][0]\nOrderedDict([('@id', 'prologue'),\n('title', 'The Beginning'),\n('para', 'This is the first paragraph.')])
                                                            \n

                                                            Or the first chapter:

                                                            \n
                                                            >>> data['book']['chapter'][1]\nOrderedDict([('@id', 'end'), ('title', 'The Ending'),\n('para', 'Last paragraph of last chapter.')])
                                                            \n

                                                            And of course, you can continue narrowing your focus:

                                                            \n
                                                            >>> data["book"]["chapter"][0]['para']\n'This is the first paragraph.'
                                                            \n

                                                            It's sort of like Xpath for toddlers. Having had to work with Xpath, I'm happy to have this option.

                                                            \n

                                                            Attributes

                                                            \n

                                                            You may have already noticed that in the dict containing our data, there is some special notation happening. For instance, there is no @id element in our XML, and yet that appears in the dict.

                                                            \n

                                                            Xmltodict uses the @ symbol to signify an attribute of an element. So to look at the attribute of an element:

                                                            \n
                                                            >>> data['book']['chapter'][0]['@id']\n'prologue'
                                                            \n

                                                            If you need to see each attribute of each chapter tag, just iterate over the dict. A simple example:

                                                            \n
                                                            >>> for c in range(0,2):\n...     data['book']['chapter'][c]['@id']\n...\n'prologue'\n'end'
                                                            \n

                                                            Contents

                                                            \n

                                                            In addition to special notation for attributes, xmltodict uses the # prefix to denote contents of complex elements. To show this example, I'll make a minor modification to sample.xml:

                                                            \n
                                                            <?xml version="1.0"?>\n<book>\n   <chapter id="prologue">\n      <title>\n     The Beginning\n  </title>\n      <para class="linux">\n     This is the first paragraph.\n      </para>\n    </chapter>\n\n    <chapter id="end">\n      <title>\n     The Ending\n  </title>\n      <para class="linux">\n     Last para of last chapter.\n      </para>\n    </chapter>\n</book>
                                                            \n

                                                            Notice that the <para> elements now have a linux attribute, and also contain text content (unlike <chapter> elements, which have attributes but only contain other elements).

                                                            Look at this data structure:

                                                            \n
                                                            >>> import xmltodict\n>>> with open('sample.xml') as g:\n...     data = xmltodict.parse(g.read())\n>>> data['book']['chapter'][0]\nOrderedDict([('@id', 'prologue'),\n('title', 'The Beginning'),\n('para', OrderedDict([('@class', 'linux'),\n('#text', 'This is the first paragraph.')]))])
                                                            \n

                                                            There is a new entry in the dictionary: #text. It contains the text content of the <para> tag and is accessible in the same way that an attribute is:

                                                            \n
                                                            >>> data['book']['chapter'][0]['para']['#text']\n'This is the first paragraph.'
                                                            \n

                                                            Advanced

                                                            \n

                                                            The xmltodict module supports XML namespaces and can also dump your data back into XML. For more documentation on this, have a look at the module on github.com/martinblech/xmltodict.

                                                            What to Use?

                                                            \n

                                                            Between untangle, xmltodict, and JSON, you have pretty good set of options for data parsing. There really are diferent uses for each one, so there's not necessarily a "right" or "wrong" answer. Try them out, see what you prefer, and use what is best. If you don't know what's best, use what you're most comfortable with; you can always improve it later.

                                                            \n

                                                            Note: Avoid prolonged contact between the kombucha and metal both during and after brewing. This can affect the flavor of your kombucha and weaken the scoby over time.

                                                            \n

                                                            1. Make the Tea Base: Bring the water to a boil. Remove from heat and stir in the sugar to dissolve. Drop in the tea and allow it to steep until the water has cooled. Depending on the size of your pot, this will take a few hours. You can speed up the cooling process by placing the pot in an ice bath.

                                                            \n

                                                            2. Add the Starter Tea: Once the tea is cool, remove the tea bags or strain out the loose tea. Stir in the starter tea. (The starter tea makes the liquid acidic, which prevents unfriendly bacteria from taking up residence in the first few days of fermentation.)

                                                            \n

                                                            3. Transfer to Jars and Add the Scoby: Pour the mixture into a 1-gallon glass jar (or divide between two 2-quart jars, in which case you'll need 2 scobys) and gently slide the scoby into the jar with clean hands. Cover the mouth of the jar with a few layers of cheesecloth or paper towels secured with a rubber band.

                                                            \n

                                                            4. Ferment for 7 to 10 Days: Keep the jar at room temperature, out of direct sunlight, and where it won't get jostled. Ferment for 7 to 10 days, checking the kombucha and the scoby periodically.

                                                            \n

                                                            It's not unusual for the scoby to float at the top, bottom, or even sideways. A new cream-colored layer of scoby should start forming on the surface of the kombucha within a few days. It usually attaches to the old scoby, but it's ok if they separate. You may also see brown stringy bits floating beneath the scoby, sediment collecting at the bottom, and bubbles collecting around the scoby. This is all normal and signs of healthy fermentation.

                                                            \n

                                                            After seven days, begin tasting the kombucha daily by pouring a little out of the jar and into a cup. When it reaches a balance of sweetness and tartness that is pleasant to you, the kombucha is ready to bottle.

                                                            \n

                                                            5. Remove the Scoby: Before proceeding, prepare and cool another pot of strong tea for your next batch of kombucha, as outlined above. With clean hands, gently lift the scoby out of the kombucha and set it on a clean plate. As you do, check it over and remove the bottom layer if the scoby is getting very thick.

                                                            \n

                                                            6. Bottle the Finished Kombucha: Measure out your starter tea from this batch of kombucha and set it aside for the next batch. Pour the fermented kombucha (straining, if desired) into bottles, along with any juice, herbs, or fruit you may want to use as flavoring. Leave about a half inch of head room in each bottle. (Alternatively, infuse the kombucha with flavorings for a day or two in another jar covered with cheesecloth, strain, and then bottle. This makes a cleaner kombucha without "stuff" in it.)

                                                            \n

                                                            7. Carbonate and Refrigerate the Finished Kombucha: Store the bottled kombucha at room-temperature out of direct sunlight and allow 1 to 3 days for the kombucha to carbonate. Until you get a feel for how quickly your kombucha carbonates, it's helpful to keep it in plastic bottles; the kombucha is carbonated when the bottles feel rock solid. Refrigerate to stop fermentation and carbonation, and then consume your kombucha within a month.

                                                            8. Make a Fresh Batch of Kombucha: Clean the jar being used for kombucha fermentation. Combine the starter tea from your last batch of kombucha with the fresh batch of sugary tea, and pour it into the fermentation jar. Slide the scoby on top, cover, and ferment for 7 to 10 days.

                                                            \n

                                                            Additional Notes:

                                                            \n

                                                            • Batch Size: To increase or decrease the amount of kombucha you make, maintain the basic ratio of 1 cup of sugar, 8 bags of tea, and 2 cups starter tea per gallon batch. One scoby will ferment any size batch, though larger batches may take longer.

                                                            \n

                                                            • Putting Kombucha on Pause: If you'll be away for 3 weeks or less, just make a fresh batch and leave it on your counter. It will likely be too vinegary to drink by the time you get back, but the scoby will be fine. For longer breaks, store the scoby in a fresh batch of the tea base with starter tea in the fridge. Change out the tea for a fresh batch every 4 to 6 weeks.

                                                            \n

                                                            • Other Tea Options: Black tea tends to be the easiest and most reliable for the scoby to ferment into kombucha, but once your scoby is going strong, you can try branching out into other kinds. Green tea, white tea, oolong tea, or a even mix of these make especially good kombucha. Herbal teas are ok, but be sure to use at least a few bags of black tea in the mix to make sure the scoby is getting all the nutrients it needs. Avoid any teas that contain oils, like earl grey or flavored teas.

                                                            \n

                                                            • Avoid Prolonged Contact with Metal: Using metal utensils is generally fine, but avoid fermenting or bottling the kombucha in anything that brings them into contact with metal. Metals, especially reactive metals like aluminum, can give the kombucha a metallic flavor and weaken the scoby over time.

                                                            \n

                                                            Troubleshooting Kombucha

                                                            \n

                                                            • It is normal for the scoby to float on the top, bottom, or sideways in the jar. It is also normal for brown strings to form below the scoby or to collect on the bottom. If your scoby develops a hole, bumps, dried patches, darker brown patches, or clear jelly-like patches, it is still fine to use. Usually these are all indicative of changes in the environment of your kitchen and not a problem with the scoby itself.

                                                            \n

                                                            • Kombucha will start off with a neutral aroma and then smell progressively more vinegary as brewing progresses. If it starts to smell cheesy, rotten, or otherwise unpleasant, this is a sign that something has gone wrong. If you see no signs of mold on the scoby, discard the liquid and begin again with fresh tea. If you do see signs of mold, discard both the scoby and the liquid and begin again with new ingredients.

                                                            \n

                                                            • A scoby will last a very long time, but it's not indestructible. If the scoby becomes black, that is a sign that it has passed its lifespan. If it develops green or black mold, it is has become infected. In both of these cases, throw away the scoby and begin again.

                                                            \n

                                                            • To prolong the life and maintain the health of your scoby, stick to the ratio of sugar, tea, starter tea, and water outlined in the recipe. You should also peel off the bottom (oldest) layer every few batches. This can be discarded, composted, used to start a new batch of kombucha, or given to a friend to start their own.

                                                            \n

                                                            • If you're ever in doubt about whether there is a problem with your scoby, just continue brewing batches but discard the kombucha they make. If there's a problem, it will get worse over time and become very apparent. If it's just a natural aspect of the scoby, then it will stay consistent from batch to batch and the kombucha is fine for drinking.

                                                              \n This bag has been with me since 2009, and for about the last 3 years did double duty, carrying both of my laptops with other assorted gear, and has held up beautifully, No fabric wear, not a stitch or seam broken anywhere. Both zippers are intact and still pull smooth and easily, they haven't even lost the pull-tabs (usually my first issue with any zipper). The handle and the shoulder strap are reasonably comfortable (for a single shoulder strap) and show no signs of wear either. Can't recommend this bag enough if you are looking for a tough messenger bag. If you are going to haul 2 laptops around (plus gear) I would strongly recommend something with 2 shoulder straps though, if you're doing any serious walking about.

I also replaced the original 750gb spinning HDD. The new drives were both samsung evo 500gb SSD's. https://www.newegg.com/Product/Product.aspx?Item=9SIA2W02DV8166 My only real gripe about this laptop is the screen resolution, which maxes out at 1366x768. IMHO, this is a waste of real estate on a 15.6 inch screen. I am looking into this, but replacement with a higher resolution screen seems to be unfeasible, from what I am reading. ( IF YOU HAVE SUGGESTIONS OR KNOW OF A SOLUTION I WOULD LOVE TO HEAR ABOUT IT!!)

I like the metal case on the toshiba. - although older, I really liked this laptop, and still prefer the keyboard (although somewhat cramped) over the one on my Toshiba. The feel of the keys themselves and the distinctive stroke and light click as you press down through the detent, just feels better than the chiclet keyboard on my newer machine. Incidentally, I once spilled a rum and coke across this thing, keyboard and all, while it was powered down. After dry out and a good cleaning, it fired up and still works. I don't recommend trying to re create this experiment though. Dumb luck, I suppose. I was sure it would be a deader.

Getting the pen's pressure sensitivity settings in some drawing programs (krita, gimp, etc) can sometimes be a bit fiddly and sometimes hard to find. Overall works quite well, although I am not a professional artist. Trucker, remember? Fun to play with, and reasonably small so its good travel size.

I know it can be done, because I see it elsewhere, I'm just too tired to figure it out now. next one. As I understand it, I owe at least 2-3 shows. Be patient with me Ken, I'm workin' on it.

                                                            In this episode I talk about how I tried to implement an idea that my son had when we were talking one day. I was complaining about file names with spaces in them, and he asked what if the computer automatically changed the spacebar so that it made underscores whenever somebody was trying to save a file? I thought this was a great idea. I even thought of a way implement it, though not quite as magically as he had envisioned. My solution involves the use of the command-line tools xev and xmodmap, and one blather voice prompt to launch the xmodmap command that will remap the spacebar to make underscores instead. Maybe somebody a whole lot smarter than me can figure out how to make this happen automatically whenever a save dialog box is open.

                                                            \n\n

                                                            First you need to find the keycode for your spacebar. Run the xev command and then press the spacebar to see which key code it is. Here's the output on my laptop:

                                                            \n\n
                                                            KeyPress event, serial 48, synthetic NO, window 0x4e00001,\n    root 0xc0, subw 0x0, time 116149126, (-739,-226), root:(448,358),\n    state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,\n    XLookupString gives 1 bytes: (20) \" \"\n    XmbLookupString gives 1 bytes: (20) \" \"\n    XFilterEvent returns: False\n
                                                            \n\n

                                                            As you can see, my spacebar has the keycode of \"65.\" Now we use xmodmap to reassign keycode 65 to make underscores:

                                                            \n\n
                                                            xmodmap -e \"keycode 65 = underscore\"
                                                            \n\n

                                                            Now to test it out. While xev is running, press spacebar. Notice that now when the spacebar is pressed it makes an underscore:

                                                            \n\n
                                                            KeyPress event, serial 57, synthetic NO, window 0x2600001,\n    root 0xc0, subw 0x0, time 116190619, (-520,-247), root:(667,337),\n    state 0x0, keycode 65 (keysym 0x5f, underscore), same_screen YES,\n    XLookupString gives 1 bytes: (5f) \"_\"\n    XmbLookupString gives 1 bytes: (5f) \"_\"\n    XFilterEvent returns: False\n
                                                            \n\n

                                                            And to change it back:

                                                            \n\n
                                                            xmodmap -e \"keycode 65 = space\"
                                                            \n\n

                                                            Now whenever I want to change the spacebar to make underscores or switch it back, I speak one of the following commands, which are in my blather configuration file.

                                                            \n\n

                                                            \n\n

                                                            Hello citizen of the Internet, my name is njulian, and in my first Episode for HPR I want to talk about an App called \"Microphone\". This App is available for Android in the F-Droid repository, link is in the Shownotes.

                                                            \n

                                                            All it does is sending the audio input from the microphone directly into the audio output. This causes horrible feedback loops, if the output happens to be the Phone's speakers. But if you plug a Male-to-Male 3.5mm cable into your Phone and the other end into your Computer you can use your Smartphone as a Microphone. Actually I am using this right now to record this show with Audacity on my Laptop. The reasons for that are pretty simple: I don't have enough free space on my Phone to record a show with Urecord and the other is that I was curious if this app really works.

                                                            \n

                                                            I've been using Linux as my primary operating system for almost 20 years now. My primary distribution of choice has always been Slackware, but I have branched out to some more "modern" distributions as well, particularly for workstation environments.

                                                            \n

                                                            I have been an HPR listener now for several months and this is my first show. I enjoy the podcast very much and hope to see it continue for many more years. Thank you to the administrators and leaders to make it all possible. And, of course, thank you to everyone that contributes shows.

                                                            \n\n

                                                            \nI love HPR and noticing our current need for shows, I put it on my list that I needed to help out. But what to talk about?\n

                                                            \n\n

                                                            \nLet’s talk about growing HPR. It is a cool show and project, but if the community does not grow the show will end. People run out of shows to host and others have to fill that space.\n

                                                            \n\n

                                                            \nI think we do a great job doing outreach to the community by going to conventions, getting mentioned in articles and magazines, and being cool with everyone. But as a community we could do a little more to get to the 4000 show mark. Even my lazy butt can help with these things.\n

                                                            \n\n

                                                            \nFirst, let’s bring more traffic to the site. To do this we need content, which is really all we have. But we need to be more clever with how we use it.\n

                                                            \n\n

                                                            \nWe need to transcribe all of our shows. This allows search engines to better index our content and bring more people to our site. Maybe they won’t subscribe or even listen to a show with the content being readable, but they were not going to listen anyway by not finding us. This is a big chore and we would need a team with leadership to do it.\n

                                                            \n\n

                                                            \nWe need more popular hosts (this sounds bad taken at face value) to guest host shows and mention HPR on their shows. We used to do this by sending in bumpers like “this is droops from Hacker Public Radio and we live whatever this show is. Hacker Public Radio is a daily show created by the community”. Let’s make a list of podcasters we want to guest host or mention our show and go after them.\n

                                                            \n\n

                                                            \nSpeaking of guest hosts, let’s work on interviewing more people who will put our show on their blog/social media. We did this in the early days of Twatech with Moka5 and we got a lot of traffic from this. I do know that we already do this, but not everyone who listens contributes a show and this is an easy way to do it.\n

                                                            \n\n

                                                            \nWhat if we made it easier to record shows? Maybe have an Android/iOS app to record and submit shows from.\n

                                                            \n\n

                                                            \nWe could have a tool to submit show topics or do a survey to find out what people are interested in. This may prompt people to record shows by knowing that someone would be interested in it.\n

                                                            \n\n

                                                            \nSomeone could get some free stock photos (or better yet we could just take our own) and put show titles over the images to share on social media. People click on images. I will do this so that everyone can see my ugly face.\n

                                                            \n

                                                            \n\n\"a\n\n\n

                                                            \n

                                                            \nOn that note, how about a video that explains what HPR is. This may be a good droops project. That would be something awesome to share on social media.\n

                                                            \n\n

                                                            \nThe website, which is a lot of work, needs to have related shows listed on each individual shows page. This will take a tag system and someone to tag all of the almost uncountable previous episodes.\n

                                                            \n\n

                                                            \nOne of my favorite show formats is reviews of software/media. This is so much in our community to keep up with and HPR is perfect for this. Everyone should do a show about some unique software they use or a cool book they are reading or a cool documentary they watched. Five minutes about something cool would bring me into learning more about it.\n

                                                            \n\n

                                                            \nCurrently my classes are watching a documentary about the Silk Road called Deep Web (https://www.deepwebthemovie.com/). I should do a show on it to talk about privacy, government, all the cool things it brings up. We have not gotten far into the documentary yet as we keep stopping it to have discussions. \n

                                                            \n\n

                                                            \nAlso I love stickers, we should set up a store to sell stickers and t-shirts. Heck this is HPR, we should have tote bags. We can either sell them at cost or make a profit to pay for hosting or swag to give away.\n

                                                            \n\n

                                                            \nHacker Public Radio is driven by the community and our community as a whole is much smarter than I am. Let’s put our minds together and grow our show.\n

                                                            Arch: On Arch Linux this is really easy. Jezra made a package build for the AUR so you can just install it that way.

                                                            \n\n

                                                            Debian: I wrote an installation script for Debian-based systems that installs the dependencies to build pocketsphinx, plus a few extra packages that I use continually when I'm running blather (xvkbd, xdotool, espeak, wmctrl, elinks, xclip, curl). It builds/installs the Sphinx stuff, pulls the blather source code, and puts some configuration files and a startup script in place for you. This should take care of pretty much all of the heavy lifting.

                                                            \n\n

                                                            I refer frequently to Jezra's usage notes on the Blather source code page at gitlab, so if you're trying to install this as I talk, you might want to follow along over there.

                                                            The trickiest bit in the initial run is the creation and placement of the language files. I normally use a bash script for this, but on this first episode of the series I'm going to use the web-based lmtool to create the language files, just the way Jezra says to do on his usage page. He also includes my automated language updater script in the blather source code, though, so going forward I will be talking about how to use that script instead of the web-based tool.

                                                            I use a bash script to launch Blather because I want to set several environmental variables: location of the pocketsphinx gstreamer libraries, default browser, default text-to-speech engine, and so forth. Having these environmental variables set means that I can use easy-to-remember shortcuts in my blather commands config file. Here is my launch script:

                                                            My first objective in making this show is to actually record a show, which is something I've never done.

                                                            My second objective was to say something interesting about why I use Linux, how I found it and why I think I keep using it.

                                                            \n

                                                            I found Linux by word of mouth. It was a bit of a hassle to use back then and I wouldn't have stuck with it if the system didn't meet my needs better than everything else that was available to me. Cost was very important at first, but as time has gone by, it's been the tools and the usability of the system that have made me stay with it.

                                                            \n

                                                            Despite their differences, Apple and Microsoft both try hard to be big, to have lots of users (buyers). They try to be everything to everyone. I think that happens with some Linux distributions too, but Linux is not one thing in the way that Windows is one thing. This means that at least some distributions can be less focused on keeping up with the latest, flashiest things. Linux just works for what I need it to do. I miss it when I'm not using it.

The tools I use most often are: Vim, git, grep, Filezilla, the LAMP stack, Meteor, Firefox, Chromium. Many of these tools are afterthoughts in other systems, whereas they seem like native inhabitants in a Linux distribution.

                                                            I was raised on wines & cocktails. But, over recent years, especially after listening to many of you guys' podcast on beer-making and drinking, I became interested in wanting to try some of these artisan beers you all have spoken of. But, being overseas in a foreign country, my chances of such are like a snowball's chance in hell. Or so I thought.

                                                            \n

                                                            Then came one night when I was on my way to teach a class at one of the local universities, and passed by a newly opened bar with the humorous name of \"Nobody Knows Bar.\" Where, when I glanced in the window and to my amazement, were many of the very beers you all had been talking so much about. Wow! Here was my chance to partake. So, I went to class and afterwards stopped in to the bar.

                                                            \n

                                                            So, I tried a beer. It just happened to be an IPA. Now, don't get me wrong. Many, many years ago I had tried an IPA and found it far from my liking. So, my first choice wouldn't have been an IPA normally. Again you ask, \"Why did you choose an IPA this time?\" Well, the reason was bartender recommended it.

                                                            \n

                                                            And again to my amazement (to coin a phrase), it was great. I guess the reason for enjoying it over before is that, as like everyone, my taste buds had changed. And truthfully speaking, I've come to like IPAs over many others.

                                                            \n

                                                            So, to no longer digress. Let me tell you what I chose and my opinions on the beer.

                                                            \n

                                                            The beer? A 12oz. 8.2% Alc. by vol., glass bottled Lagunitas Brewery's Lagunitas Unlimited Release Maximus IPA Maximus Ale. I love the labeling. It reads: \"Life is uncertain. Don't dip.\" Also, \"If some is good, more is better.\" And one final one, \"Instant gratification isn't fast enough.\" What a lark!

                                                            \n

                                                            Enough diddle dallying. On to the tasting: The nose on this beer is crisp and light. The first mouthing brings a floral, fruity semi-sweet taste. The fruitiness continues into the aftertaste with an added semi-dryness. And yet, despite the alcohol content, doesn't ring your clock. The longer after flavor is strongest on the underside of the back of the tongue. Very pleasant.

                                                            \n

                                                            So. There you have it. My first beer tasting. I hope you found it telling. And maybe you too will try a bottle. I highly recommend it. I will continue these tasting over the course of time. Now don't get me wrong. I'm no sot. And I still like my coffees, but I have now found a new \"like\" and it's artisan beers.

                                                            \n

                                                            \n\"hand

                                                            \n\n

                                                            Until next time. This is MeToo signing out and wishing you happy trails and happy beers.

                                                            As we saw in the last episode 1951 (and others in this sub-series) there are eight types of expansion applied to the command line in the following order:

                                                            We will look at process substitution and word splitting in this episode but since there is a lot to cover in these subjects, we'll save pathname expansion for the next episode.

                                                            Hubot uses individual CoffeeScript scripts to provide chat-bot functionality. There are a slew of existing scripts available in the npm. Just search for hubot-scripts.

                                                            \n

                                                            You can also write your own in order to make sure that Hubot provides the functionality that you need.

                                                            \n

                                                            Install

                                                            \n

                                                            Hubot is available as an npm package. So, you will need to install node.js and npm on your system. I will leave this as an exercise for the listener.

                                                            \n

                                                            I will however, throw out a tip for those of you using a Raspberry Pi for this. The node.js platform should be deployed on an ARM system using the armhf (ARM hard float) architecture. The nod\ne.js stack needed to run Hubot will not properly install if you are using the armel (ARM soft float) architecture.

                                                            \n

                                                            Once you have node.js and npm installed, you can install hubot and its dependencies with the following command.

                                                            \n
                                                            npm install -g hubot yo generator-hubot coffee-script
                                                            \n

                                                            You create your own instance of hubot by using yeoman generator. You need to do this as a non-root user. When you create your bot, you will give it a name and\nspecify the adapter to use. These can be specified as command line flags, or the generator will prompt you for this information.

                                                            \n
                                                            ./bin/hubot --adapter shell
                                                            \n

                                                            Our Hubot instance is now active and ready to receive commands. We will start with a simple ping command.

                                                            \n
                                                            mybot> mybot ping\nmybot> PONG
                                                            \n

                                                            We can see the available commands by asking Hubot for help

                                                            We will try a couple more.

                                                            \n

                                                            You can add your own custom scripts by adding them to the scripts directory. An examples.coffee script was included when Hubot was installed. It includes a variety of examples of things Hubot can do. I will illustrate by paring this down to a simple single script that responds to requests to open doors. Our simple script will open most doors, but will politely refuse to open the 'pod bay' doors.

                                                            \n

                                                            The script uses the respond method on the robot module. This method takes a regex patten to respond to. It returns a result that contains a match array when the pattern has been detected. In our script we capture the group between 'onen the' and 'doors'. We then use this to determine which response to provide. The response is triggered with the robots reply method.

                                                            \n
                                                            module.exports = (robot) ->\n\n robot.respond /open the (.*) doors/i, (res) ->\n   doorType = res.match[1]\n   if doorType is "pod bay"\n     res.reply "I'm afraid I can't let you do that."\n   else\n     res.reply "Opening #{doorType} doors"
                                                            \n

                                                            Restart Hubot by...

I really like this feature and I assign the '!' as my Hubot alias. This allows me to invoke Hubot with a single character.

Hubot comes with several adapters that allow it to integrate with existing chat systems. These include: * IRC * XMPP * Campfire * HipChat * Slack * IRC * IRC

Personally, I use Hubot in a variety of ways ranging from silly entertainment to useful communication tool. Using the eight-ball script, I can see if I will have a good day.

                                                            Hi everyone,

                                                            \n

                                                            It's MeToo here again recording for HPR with a follow on beer tasting podcast. Let me first apologize for the audio quality of this and the next eleven beer podcasts. They were all recorded live on my phone in the Nobody Knows Bar, so there is a bit of a background noise. I just hope it's not too distracting.

                                                            \n

                                                            The following twelve beer podcasts were recorded over a period of several months. A couple of them, even though they were recorded at the same \"sitting\", I've chosen to break up into several podcasts, just so as to add more podcasts to HPR.

                                                            \n

                                                            In a few cases, it's obvious that I get a little tongue tied. Please forgive me. I normally tend to just have one beer per sitting, but the beer is so good and I'm with friends, and as such have had more than one per sitting at those times.

                                                            \n

                                                            But enough of the explanations and apologies. Let's get on to the heart of the podcast: my impressions of several beers.

                                                            \n

                                                            One more thing before we start. The beer in this podcast is Old Foghorn. I mislabeled it in the recording as Old Fog.

                                                            Well. there you have it. Not one of my better recordings. But I hope you liked it nonetheless.

                                                            \n

                                                            In this episode I show how to start adding more commands, how to use the language updater script, and how to start doing some basic desktop navigation. I'll show you how to open and quit applications, and how to switch from one application to another using your voice.

                                                            \n\n

                                                            For information about installing blather for the first time, as well as the startup script that I use, please refer to episode 0 of this series, which has examples and links for this stuff.

                                                            \n\n

                                                            To start using the language updater script, you need to move it or copy it from the blather source code directory into your path (e.g. ~/bin/). To add new commands you will have to edit the main command configuration file:

                                                            \n\n
                                                            ~/.config/blather/commands.conf
                                                            \n\n

                                                            Commands are configured in a \"key: value\" pair, where the key is what you wish to say, and the value is the command that will be executed when you say it. We will start out with some very basic ones, but these can be as elaborate as your imagination and scripting skills will allow. You can execute built-in system commands, or you can write your own scripts that will be executed upon the voice command.

                                                            \n\n

                                                            Here's an example of a basic desktop application command set:

                                                            \n\n\n
                                                            OPEN CHROMIUM: chromium &\nGO TO CHROMIUM: wmctrl -a \"google chrome\"\nQUIT CHROMIUM: wmctrl -c \"google chrome\"\n
                                                            \n\n

                                                            The first command launches Chromium, the second one will switch focus to Chromium when you are currently in another program, and the third one closes Chromium. This makes use of the command line tool wmctrl, which is a very handy window management tool. The wmctrl -a command chooses which window to put focus on (or close) based on the window title, which in the commands above is given in quotation marks. There are many options to how wmctrl can find windows and take actions, but for now we will just use this basic option.

                                                            \n\n

                                                            Once you have one command set of this kind working as you like, it's very easy to set up additional command sets for all of the desktop applications you use most often.

                                                            \n\n

                                                            Some applications are more difficult to handle than others. For example media players typically change the window title based on which track is playing. This makes it impossible to use the static window title option above, so I resort to a bit of scripting to help it find the right window to put focus on or close:

                                                            \n\n
                                                            OPEN clementine: clementine &\nGO TO clementine: rid=$(pgrep clementine -u $(whoami) |head -n 1) && rwinname=$(wmctrl -lp |grep $rid |sed -e \"s/.*$rid * //\" | sed -e \"s/$(hostname) //\") && wmctrl -a \"$rwinname\"\n
                                                            \n\n

                                                            Opening the music player is easy. Switching to it is something else. To make this work I first find the process ID of the Clementine music player, and then I use the wmctrl list command to list all of the windows that are open and I grep for the process ID that I found in the first part. Then I extract the window name from that command's output and use the result inside quotation marks in the very last command to change Focus to that window. Whew!

                                                            \n\n

                                                            One last basic desktop navigation command for this episode. This is one that I use probably more than any other command. What it achieves is the alt + Tab Key stroke, which switches Focus to the previous window. Here's how I do it:

                                                            \n\n
                                                            \nBACK FLIP: xdotool key alt+Tab\n
                                                            \n\n

                                                            This makes use of the wonderful xdotool package to execute a virtual keystroke. Magic!

                                                            \n\n

                                                            Yesterday I listened to an episode of Freakonomics (https://freakonomics.com/podcast/who-needs-handwriting/) on handwriting. As a child I disliked penmanship and was horrible at it (still am). Eventually my teachers just told me to print so that they could read my answers. This is also a tech show, which should have an audience that leans toward the fact that computers are awesome. But most of you fine listeners should be interested in what is the best solution to a problem. Especially if that solution is contrary to conventional thought.

                                                            \n

                                                            Many reasons were given for handwriting to be a thing of the past and I think most of them are a lot of bull.

                                                            \n

                                                            First some more qualifications for me. I am a college dropout that did eventually graduate. Until last week I was a teacher who worked with students who were not always the best. I have been without a cell phone for two years and I love fountain pens. This probably does not qualify me for much, as I am certainly not a doctor or a scientific researcher, but I do have some real world experience and have been experimenting on my students (all in a good way).

                                                            \n

                                                            So here are some of the cons:

                                                            \n
                                                              \n
                                                            • Handwriting is old fashioned – true
                                                              • \n
                                                            • Typing is faster – true. Cursive is on average 30 words per minute.
                                                              • \n
                                                            • Hands hurt after writing – true
                                                              • \n
                                                            • Lack of success as a child demotivated me, left me “school damaged” – true
                                                              • \n
                                                            \n

                                                            These are all excuses that I have made and are all excuses my students have made. As a computer science teacher, I require all of my students to keep a handwritten notebook in my classes and they can use it on all of their tests, quizzes, and assignments. What an old fashioned stick in the mud I must be (they must have a cooler way to say this).

                                                            \n

                                                            There is nothing wrong with using tech to help with anything, but if you do not understand concepts of why and how, all the tech in the world will not help you and many people try to use tech as a crutch.

                                                            \n

                                                            Typing is faster, most students get to the point they can type everything that is said in a lecture. This skips a crucial part of learning where you use your brain to analyze what is being said. Writing is slower but should force you to put content in your own words by thinking about it and being an active listener.

                                                            \n

                                                            The pain in your hand should go away with practice, good form, and proper tools. I like fountain pens as they glide over the paper and you do not have to hold them in a death grip. Form means to use your arm, not your wrist, to write. With practice this can be done.

                                                            \n

                                                            I was bad at handwriting as a child and my teacher was wrong to tell me to stop. Part of education is to teach about failure and difficulty. If people only do the easy things who will do the hard ones? A person interviewed on Freakanomics said their school put too much emphasis on handwriting so they moved their child to a different school as this was having too much of a negative effect on his feelings. Way to teach your child to run away from hard things. I hope no college professor ever hurts his feelings to requires too much from them. Life gets harder, education should be hard to prepare students for the work of life.

                                                            \n

                                                            So enough cons, how about some pro argument.

                                                            \n

                                                            Laptops are full of distractions, most adults I know cannot focus with their email and social media trying to grab their attention.

                                                            \n

                                                            In an independent study talked about on Freakanomics, two researchers found that handwriters and laptopers had no difference in learning faces, unless they were allowed to review their notes before the quiz, where handwriters gained an edge. Concepts on the other hand, handwriters always held and almost like they thought about the concepts more than the students who just typed everything that was said.

                                                            \n

                                                            Something not really covered was writing new content. I give my students fountain pens as rewards and this makes writing so much more special. They take more time to write things and think more about what they are trying to say. This is a win-win.

                                                            \n

                                                            Now everyone is different. Please try handwriting for a few weeks and see if it helps you retain more. If you are not a student, watch a lecture on the internet or read a book and see if you learn more.

                                                            \n

                                                            Finally handwriting is personal. I am willing to mail a postcard to almost anyone that sends me their address (droops @ gmail) so that they can get that personal feeling.

                                                            \n

                                                            So I made some arguments, handwriting makes you smarter, helps you develop grit, makes you feel special, and gives you super powers. Hopefully you will try it out.

                                                            I’d like to start by apologising for the rather fast and excited speaking style of this show particularly towards the end, hope it doesn’t spoil the content too much, it was all done in rather a hurry.

                                                            \n

                                                            In this show I describe a thought provoking documentary I stumbled upon from 1977, the documentary is about the the silicon chip and explores the far reaching implications it will have on society.

                                                            \n

                                                            The title for the original documentary was “Now the chips are down”.

                                                            \n

                                                            I came up with the altered title “Now the chips are definitely down” to signify that not only have the changes already happened but that it’s also had a massive cost reduction impact as my newly purchased piece of equipment demonstrates.

                                                            \n

                                                            The new piece of equipment that I bought only became so affordable because of the great advances and massive reductions in cost over time. A similar piece of equipment cost me around £120 maybe ten years ago and due to inflation you can probably double the cost again. The price of my new piece of equipment was astonishingly cheap I thought though on reflection its cheap price may also be down to it being a more mass produced item than normal amateur radio equipment.

                                                            When I took over as Director of the School of Music in January, one of the first things I did was to try to get a better handle on the number of faculty I had at various ranks, how many had terminal degrees, how many already had tenure, how many were on tenure track, how many held endowed professorships, and so forth. Somewhere in the process, I discovered a handy trick for generating reports for this kind of thing. It's the COUNTIF function of LibreOffice calc. In this episode I will go through some examples of ways that I've used COUNTIF to generate reports.

                                                            \n

                                                            We all use GNU Readline if we we use the CLI in Linux because it manages input, line editing and command history in Bash and in many tools.

                                                            \n

                                                            I have been using Unix and later Linux since the 1980's, and gradually learnt how to do things like jump to the start or the end of the line, delete a character backwards up to a space, or delete the entire line.

                                                            \n

                                                            I think that learning GNU Readline is worthwhile since it contains a lot more features than what I just described. I thought I would do a few episodes on HPR to introduce some of what I consider to be the most useful features.

                                                            This is a very personal podcast, discussing minor surgery. If that sort of stuff makes you cringe at all, this may not be the recording for you. I should also point out that I am not a medical professional, you should not take this recording as medical advice, if you have any concerns about your skin, seek professional medical advice.

                                                            \n

                                                            I am a very white person living in Queensland, Australia. Our state has amongst the highest rate of skin cancers in the world, I believe we're in a tussle with New Zealand for first place at the moment.

                                                            \n

                                                            There are two main types of skin cancer, melanoma and non-melanoma. The non-melanoma type is slow growing, and rarely spreads to other parts of the body, while melanoma is fast growing and spreads to the rest of the body.

                                                            \n

                                                            Both my parents have had multiple lesions excised, so something like this was always on my mind. We live in a sunny, sub-tropical environment, the sort of clothing you'd want to wear for comfort is light, breezy, and not covering much skin, exactly the wrong sort of clothes you'd need to wear to protect yourself from ultraviolet (UV) rays that help cause skin cancer.

                                                            \n

                                                            According to the Australian BoM FAQ https://www.bom.gov.au/uv/faq.shtml the per capita risk of skin cancer in Australia is ten times higher than America and sixty times higher than the UK.

                                                            \n

                                                            The UV scale rarely gets above eight in the UK, in Brisbane the UV scale is above eight for roughly eight months of the year.

                                                            \n

                                                            There are a lot of variables when it comes to UV. Cloud cover is probably the most important. Something that I can't stress enough is that heat and UV are not correlated, you can definitely be exposed to lots of UV when it's cold (see New Zealand, they're much more south, much more cold, and have more exposure due to the ozone hole). Another example is snow, UV will bounce off the snow and back at you.

                                                            \n

                                                            The link between skin cancer and UV is quite strong, 95-99% of skin cancers are caused by excess sun exposure. (https://www.cancer.org.au)

                                                            \n

                                                            So, with all that history, I started getting yearly skin checks a couple of years ago. I'd had a couple of skin checks when I was very young, and now that I'm more advanced in years I wanted something less ad-hoc. Someone working for one such organisation gave a talk at one of the user groups I attended, and i made an appointment with Molemap. It's a full on procedure where your entire body is photographed, and each mole, freckle, bump and lump that is of possible concern is photographed from a few centimetres off the skin, and with the magnification lens sitting right on top of the mole.

                                                            \n

                                                            I have some near 200 spots on myself that are of interest, so my follow up appointments take about two and half hours to go over all these spots, plus looking for new ones. The hope is that, by doing this close to yearly, small changes in all these spots won't go unnoticed, and we can get on top of any cancers early.

                                                            \n

                                                            Interestingly, the spot that was actually a problem was a new one, so under a year old, and was hiding underneath my beard, so in future I'm definitely going to have my skin checked clean shaven.

                                                            \n

                                                            The other thing I want to communicate is that early detection is key, all the skin cancers have a 90% plus survival rate (at five years) if caught early enough. This does potentially mean that a yearly check is not enough, but it's already proven it's worth to me.

                                                            \n

                                                            Molemap only does photography of spots, and visual diagnosis. It does not do any treatment or biopsies or excisions, therefore there it has no self interest in recommending treatment on borderline cases. Molemap sprang out of a University of Queensland project, which is my alma mater. After receiving the diagnosis (via an online form, secured with a second factor sent to my phone) and panicking a fair bit, I contacted my regular doctors practice (we call them general practitioners in Australia, I'm sure they're called different things elsewhere) for an appointment with a GP who had experience with skin cancers. In QLD, most medical centres will have at least one doctor with experience in this area. As it turns out, my regular GP has such experience and I got an appointment for the following week.

                                                            \n

                                                            I wasn't really sure what to expect from my GP appointment, but I was mostly expecting to get the diagnosis confirmed, and either get sent to a specialist to deal with it, or organise another appointment at the GP.

                                                            \n

                                                            What actually happened was it took all of five minutes for my doctor to confirm the diagnosis, then work how he had time in his schedule, and there was a nurse free, to excise the lesion straight away. I was given a local anaesthetic, so I felt no pain whatsoever, but you still feel the doctor pulling on your skin up, down left and right, so that the complete lesion can be removed, as well as a small amount of surrounding skin in case the cancer has spread.

                                                            \n

                                                            Here I should mention that melanomas spread very fast, and when they're excised up to a centimetre of skin may need to be removed, where as for a non-melanomic, a millimetre or so is good enough.

                                                            \n

                                                            I got four sutures put in, they stayed for a week (we have a long easter break in Australia) so it ended up being closer to a week and a half. I had no problems, my scar healed up quickly and nicely. Now, a couple of months later, there's a little redness along the scar line, but that's about it.

                                                            \n

                                                            So. The take aways. UV is not correlated to heat, you can get a lot of UV exposure in cold environments. If you're travelling through a high UV area, take precautions (clothes that cover a lot of your skin, hat, sunglasses, sunscreen). If you live in a high UV area, get your skin checked regularly. Also, keep an eye on your own skin. Use a diary to record any new bumps, lumps, spots etc.

                                                            Hi This is Tony Hughes for Hacker Public Radio, I'm trying to do a show once a month or so and I was thinking of ideas that might be of interest to the listeners out there.

                                                            \n

                                                            While there are regular shows on 'What's on my pod-catcher' I've never heard one about what magazines that people in the HPR community like to read. With the advent of digital media and subscription services such as Issuu, Magzter, Google Play Newsstand and I'm sure many others which offer both Free and subscription content I'm sure many of you like me have quite a number of magazines you regularly read, and some you dip in to from time to time. So this show is about the Magazines I like to read.

                                                            \n

                                                            First I'd like to say that to facilitate regularly reading of digital media I feel for me a 10" tablet is the smallest format for comfortable reading (although for those of you with young enough eyesight to be able to read small fonts with no difficulty you may feel different). However my Tablet of choice is the 12" Samsung SM-P900 which I purchased in February 2015. My only gripe with this tablet is I'll probably never get Android 6 on it as it's now over 2 years since original release. While I agree with Apple that the 4:3 screen configuration for reading on a tablet is more user friendly I can not bring myself to spend that kind of money or be tied to the Apple ecosystem.

Good content for and about Linux and the Linux community and they support the community by distributing 50% of their annual profits back to the Open Source Community after a ballot of readers. They also release issues of the magazine with a creative commons licence 9 months after publication. This is the only magazine I currently have a Paper subscription to (it also comes with a free DRM free PDF copy for subscribers)

They still have a weekly Linux page and regular Raspberry Pi and other Linux related content.

                                                            In this episode I take you along for the ride as I do a little bit of maintenance on my pickup truck. I've been trying to track down the source of of a rough idling problem that sometimes turns into stalling out. I already replaced the fuel filter (did not solve the rough idling problem but probably was due anyway), and here I make an audio recording as I clean the throttle body, which apparently is one of the first things you should do when your vehicle is idling roughly and stalling out. Still not sure if I have totally fixed it but it seems to run OK so at least I did not mess it up any worse.

                                                            The list of mail threads above date from a time when HPR mailing list\nmessages were copied to Gmane. At that time the Mailman mailing list software\nused to run the list seemed not to be able to archive messages, or possibly\ncouldn't make them visible. We built lists of threads by reading the Gmane\ndata and showed them here.

                                                            \n

                                                            Since then Gmane has failed, and been restored, but the HPR lists have been\nlost. However, a later version of Mailman made these messages available as\nthey should have been, so nothing was actually lost!

                                                            Hi Hacker Public Radio this is Tony Hughes again with the second episode about the magazines I like to read. All of the magazines I’ll be talking of today I read on my Magzter (www.magzter.com) Application on my tablet. I have a Magzter Gold subscription which gives me access to literally 100’s of magazines.

                                                            \n
                                                              \n

                                                            • Vegetarian Times (www.vegetariantimes.com)
                                                              \nI’m a bit of a foodie and have been a vegetarian for many years, so access to good food magazines is important to me. This is a US publication so not all the advertised products are available in the UK but the articles and recipes are excellent.

                                                              • \n

                                                            • Feel Good Food (www.womanandhome.com/recipes/534618/feel-good-food-mag)
                                                              \nA British magazine aimed at Women but non the less still a source of some brilliant recipes for delicious food for food lovers everywhere. Not a veggie magazine but there is usually something of interest. Like most of the food magazines I read I dip into them find recipes I like save them and move on.

                                                            Moving on from food to Sci Fi and cult fiction.

                                                            \n\n

                                                            I’ve grouped these together as they both deal with this subject. They review the latest books, films, TV, comics and audio recordings for this genre . They also cover classic examples, often examining work from the so called golden age of a particular subject. Along with Total Film magazine (www.gamesradar.com/totalfilm) you will always have access to reviews of the latest films & TV and if they are worth the price of a cinema ticket or space as a series record on your PVR.

                                                            \n

                                                            Another armchair hobby of mine is archaeology I’ve loved Time Team from the beginning. So my next magazine on Magzter is Archaeology (archaeology.org) this is a bi monthly magazine published in the US, but covering the latest archaeological news from around the world. For someone into my modern technology its interesting to read about what the latest technology was hundreds or even thousands of years ago.

                                                            \n

                                                            Moving on, one of my other interests over the last 20 years has been motorcycles although I no longer ride I still retain an keen interest so a Bike magazine has to be something I dip into to drool over shiny metal every so often. So I currently have Back Street Heroes (www.backstreetheroes.com) as a favourite in Magzter and dip into it when I need a shiny metal fix.

                                                            \n

                                                            Finally a more active hobby of mine is photography so there has to be a photography magazine in this list. Amateur Photographer (photographer.magazinesdirect.com) claims to be the worlds oldest weekly photography magazine. It covers all aspect of photography and the equipment you need. From high end Professional stuff to point and shoot cameras, and all the other stuff from bags to flash lights.

                                                            This is a show describing how I solved a problem of using my new Blinkstick Nano in Python, the problem occurred because I inadvertently installed the blinkstick module to the wrong version of Python as I have multiple versions of python installed on my raspberry pi.

                                                            \n

                                                            A blinkstick is a USB powered device with attached RGB led’s, it can be controlled using a wide range of languages, and supports the Raspberry Pi, Linux, Microsoft Windows & Apple

                                                            \n

                                                            As a side note I forgot to mention that the blinkstick hardware and software is Open Source

                                                            \n\n

                                                            Initially I blindly followed the advice given at https://www.blinkstick.com/help/raspberry-pi-integration which recommended the following commands

                                                            \n
                                                            sudo apt-get install -y python-pip python2.7-dev\nsudo pip install blinkstick\nsudo blinkstick --info\nblnkstick --add-udev-rule
                                                            \n

                                                            I discovered that the blinkstick module was not being found when I ran my python script, this turned out to be because I was invoking a different version of python in my script from that which I installed the blinkstick module. I installed the blinkstick module to Python 2.7, my script was running python 3.2

                                                            \n

                                                            I ran the following commands to rectify the problem

                                                            \n
                                                            sudo apt-get install -y python3-pip\nsudo pip-3.2 install blinkstick\nsudo blinkstick --info (Run in my script)\nblinkstick --add-udev-rule (Not required 2nd time round)

                                                            Here are some links I looked at to get some understanding of what was going on

                                                            The detox utility renames files to make them easier to work with. It removes spaces and other such annoyances. It’ll also translate or cleanup Latin-1 (ISO 8859-1) characters encoded in 8-bit ASCII, Unicode characters encoded in UTF-8, and CGI escaped characters.

                                                            This is an interview with Dr Tom Kane and his student Euan Livingstone in Tom’s office at Edinburgh Napier University (ENU) on 2016-07-06.

                                                            \n

                                                            Tom and Euan are investigating ways of running GNU Health for evaluation and demonstration purposes, using multiple Raspberry Pi systems and an Intel NUC. In particular they want to evaluate the conformity of interoperability (FHIR) standards, and are trying to build a reference implementation for decision makers who are procuring a Health and Hospital Information System.

                                                            \n

                                                            In the interview Tom used some terminology that I have provided links for here and at the end:

                                                            \n\n

                                                            I had forgotten where I’d seen Luis Falcón, originator of GNU Health, being interviewed. It was on FLOSS Weekly, as linked below.

                                                            In this episode I talk about how to set up custom keystrokes so that you can launch or switch to applications easily using the super key on your keyboard. I do this on the classic Gnome desktop environment and have not tested it on Gnome 3 or Unity to see whether it works on those.

                                                            \n\n

                                                            To create a new custom keystroke, open System Settings, then go to Keyboard and Shortcuts. Click on the plus sign to open the dialog box where you specify the name of the keystroke and the command that is to be launched when the keystroke is executed. Click \"Apply\" and then click \"Disabled\" and it will allow you to type the keystroke you want to use.

                                                            \n\n

                                                            At this point the keystroke configuration is ready, but you have to either log out of the current session and log back in, or find some other way to reload the desktop environment configuration before you can actually use the keystroke.

                                                            \n\n

                                                            I also talked about how I use my own scripts to check to see whether a program is running, and then either switch to that program if it's running or launch it if it's not. Here is an example for launching or switching to LibreOffice.

                                                            \n\n
                                                            #!/bin/bash\n\n# Look for the string "LibreOffice" on the list of \n# window titles and check the return code\n\nchecktitle=$(wmctrl -l | grep "LibreOffice" &> /dev/null ; echo $?)\n\n# If the return code is 0 that means it found the \n# string, so I use wmctrl to switch to the window \n# that has that string in the title. \n\nif [ $checktitle == 0 ] ; then\n    wmctrl -a "LibreOffice"\n    \n# If it returns a 1, then that means it did not \n# find a window with that string in it so I \n# launch the application.\n    \n  else\n    loffice &\nfi\n
                                                            \n\n

                                                            Save the script somewhere in your PATH, make it executable, and then use the script name in the command when you're setting up the keystroke.

                                                            I had the opportunity to present a talk on SSL Certificates at our local LUG, the Washtenaw Linux Users Group, which uses some material from a previous HPR episode, but may be of interest to our listeners nonetheless. Because this was a lengthy presentation I have divided it into sections. This first section explains how SSL Certificates work, and the second one will explore some of the problems that we have with SSL Certificates, and how we might address those problems.

                                                            Hi HPR listeners this is Tony Hughes talking from Blackpool UK

                                                            \n

                                                            I did a show a few weeks ago about my Geek Bags but didn’t talk about the Desktop PC I use and as I’ve just upgraded to a new (used) PC I thought I would tell the story of my Desktop PC’s over the years.

                                                            \n

                                                            I was a latecomer to the world of personal computing having been at school in the Late 60’s and early 70’s when we hadn’t even got calculators, if you were lucky to be able to work out the intricacy of it you may have had use of a slide rule. Even after calculators started to be more widely used I had a lecturer at college while studying marine engineering, that was so good with his slide rule and mental calculation, he could, and would often work out equations far faster than those of us using a calculator.

                                                            \n

                                                            I first came across my first IBM clone PC back at college in 1987 while studying a control systems course this was a Intel 286 PC which the college ran CAD/CAM software on and we used it to learn how to create engineering drawings electronically. This would be the last time I used a computer until the early 1990’s when by then I had changed career and become a Registered Nurse. I was working in a residential nursing home and we had access to a Windows 3.xx PC which I would use to create templates of the clinical paperwork we used for record keeping.

                                                            \n

                                                            Around this time I met my then wife to be and she needed a PC for the University Course she was on so we obtained a used Intel 386 PC from a Friend and upgraded the Ram from 1Mb to 4Mb which cost nearly half the price we paid for the PC £120, which in 1993 was a good chunk of cash. It was a time when there was a world shortage of Ram and offices were getting burgled just for the memory in the office PC’s.

                                                            \n

                                                            While we had this PC in the house it didn’t much interest me at the time, this was pre internet days for the average user, we weren’t on line at work and the Word processing software was Dos based and I hated using it, so would do the odd things I needed to at work during my break.

                                                            \n

                                                            Move forward 5 years and Windows 95 had taken over the world and there was this wonderful new OS called Windows 98 starting to appear in the shops. In September 1998 I went back to do a Nursing Degree in my specialist area of practice and found that we were required to submit all our course work in word processed format, no long hand written assignments this time around. So I decided that I would invest in a new home PC.

                                                            \n

                                                            There were a couple of Big Box PC retailers in the UK at the time that advertised heavily in the press and on TV and I chose to go to one of these and bought a PC with the following specs:   

                                                            \n

                                                            Pentium 2 350 CPU, 128Mb Ram, 6Gig HDD, 56k modem and a DVD Rom. It also came bundled with a Scanner, Inkjet printer and software including MS Office for small Business. All for the grand total of £1400 which at the time was about a month’s take home pay so I had to pay for it with the flexible friend (my Credit Card for those of you too young to remember the ad’s)

                                                            \n

                                                            I also signed up for an AOL account to access the internet over the 56k modem, dog slow now but at the time was the only affordable way us mere mortals could afford home internet access. I remember it could take a minute or 2 to render my Bank’s web site when I started online banking in 2001 and that was using compression software to reduce the bandwidth.

                                                            \n

                                                            I used that PC to write all my college work and with the help of a couple of friends started to tinker with the PC, getting a 120 ZIP drive for it, and later adding a CD RW drive for storing documents and Photos that I’d scanned and later taken with my first digital Camera.

                                                            \n

                                                            By 2002 the PC was starting to get a bit long in the tooth and I decided it was time for an upgrade and I had a PC built for me by a local shop with P4 2.5Ghz CPU 40Gig HDD and 512Mb Ram (later upgraded to 2Gig) and a CD RW drive again later upgraded to DVD RW drive. This PC cost me half of what I paid for the P2 four years previously and was to be the last PC I bought new, all the PC’s including laptops I’ve owned since this PC have been second hand. Some given by family or friends, some built from parts of Freecycle/Freegle, and lately PC’s I’ve bought at a local computer auction in the north west of the UK.

                                                            \n

                                                            The title of this podcast is “New Toys” and so to the juicy bit, my Desktop for the last 6 years has been a Lenovo ThinkCentre 7373 Core 2 Duo PC with a 2.6Ghz CPU, 250Gig SSD, an upgrade from the 160Gig HDD it came with and 12Gig Ram also upgraded from the 4Gig it came with and requiring a bios flash to get the MB to support 16Gig. This rig has served me well but lately I have found it starting to feel its age and taking a long time to do things I now do regularly such as video and photo editing, Audio editing and virtual PC’s in virtualBox. So I decided it was time I looked around for an upgrade. As usual I was not in the market for a new PC, I could afford one but I don’t like splashing the cash unnecessarily. As luck would have it the monthly Auction catalog included a HP Compaq Elite 8300 i7 Micro Tower. I checked out the specs and liked what I read. So Monday 1st of August I took a trip to the auction and as luck would have it I became the proud owner of said PC for the princely sum of £212.80, hammer price of £190 plus commission.

                                                            \n

                                                            The full spec of the PC is: i7 3.4Ghz CPU (22nm architecture) 4 cores and 8 threads, 8Gig Ram Supports 32Gig 500Gig HDD, DVD RW drive and a card reader. Also came with a Win7 pro CoA but no installed OS.

                                                            \n

                                                            So it took me 10 minutes to install Linux Mint 18 and another 30 to complete the updates and install my software over and above the base install. It boots in just over a minute, which is only slightly slower than the old PC with an SSD, so I guess it will boot mega fast with an SSD upgrade, which is on the cards after I return from Holiday as may an upgrade to the Ram. I’ve already used some Ram from the old PC to increase to 12Gig but I need some matching 8Gig Ram to go to 16 or higher.

                                                            \n

                                                            Well that charts my PC hardware journey over the last 20 odd years it’s amazing to think that one of the Raspberry Pi 3’s I own has more processing power than most of the hardware I’ve had up to the Core 2 Duo in 2010.

                                                            Introduction

                                                            \n

                                                            At my work, we are in the process of revamping our internal call logging system. Moving from .NET and Microsoft’s ASPX pages for both the client side and back end processing, to an HTML5 based Single Page Application (SPA) using AngularJS for the client side interface with a .NET WebAPI service for the back end processing. The main page for both versions contains a list of the current days calls laid out in a table with 9 columns. Users are able to switch to a specific day’s calls by selecting a date via a calendar widget, or by moving one day at a time via previous and next day buttons. By the end of a typical day, the page will contain between 40 and 50 calls.

                                                            \n

                                                            During recent testing of the SPA client on the proprietary browser we all love to hate, or at least have a love/hate relationship with if you have to support it, I noticed that rendering of a whole days worth of calls would take seconds, freezing the UI completely. This made changing dates painful. As we reload the data any time you re-enter that page (a manual way to poll for new data until we implement either timer based polling or a push service through websockets), the page was almost unusable. The page rendered fine in both Mozilla and webkit based javascript JIT engines, but Microsoft’s engine would choke on it.

                                                            \n

                                                            After a bit of searching on “AngularJS slow rendering” and “AngularJS optimize”, I found many references about using Angular’s ng-repeat directive when rendering long lists of data (see references below for the main pages I read). I tried a couple of the methods mentioned to optimize the ng-repeat directive. I used the “track by” feature of ng-repeat to use the call’s id as the internal id of the row, so ng-repeat didn’t have to generate a hashed id for each row. I implemented Angular’s one-time binding feature to reduce the number of watches being created (reducing the test day’s number of watches from 1120 to 596), but even these two combined optimizations didn’t have enough effect to render the page in an acceptable amount of time. The next optimization I played with was using ng-repeat with the limitTo filter. This limits the number of items rendered in the list that ng-repeat is looping through. This is particularly useful combined with paging of the data. I set the limitTo option to different values to see how it affected the rendering time. I found that rendering 5 rows was fast and consistent for every day’s worth of data I viewed. From my reading, I knew if I updated the limitTo amount while keeping the array of items the same, ng-repeat would only render any un-rendered items, and not redo the whole limited list.

                                                            \n

                                                            The Code

                                                            \n
                                                            <tr ng-repeat="c in results | limitTo:displayRenderSize">
                                                            \n

                                                            Inside your directive, set an angular.$watch on the list of items to be rendered by ng-repeat. In this example the list is stored in the variable results.

                                                            \n

                                                            Any time the results are updated. The displayRenderSize variable is reset to render the default number of items, and the updateDisplayRenderSize function is called. This function calls itself repeatedly via angular’s $timeout service ($timeout is a wrapper for javascript’s setTimeout function). It increments the displayRenderSize variable which is being watched by the limitTo filter of the main ng-repeat. Each time the displayRenderSize variable is incremented, the ng-repeat renders the next set of items. This is repeated until all the items in the list are rendered.

                                                            \n

                                                            The magic happens because ng-repeat blocks any other javascript, which does not effect angular’s digest path, until it is finished rendering. By calling the updateDisplayRenderSize with a timeout, the function doesn’t get called again until after the next set of items is rendered. Making the $timeout delay 0, sets the function to be called as soon as possible after the ng-repeat digest cycle stops blocking. In this instance, the sum of the rendering time for parts of the list is shorter than the sum of the rendering time for all of the list at one time.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            There are a couple small glitches with this solution. Scrolling can be a bit jerky as the chunk sized renders cause a series of micro UI freezes, instead of one big long one. Also, if you don’t have a fixed or 100% percent wide table layout, and you don’t have fixed column sizes, the table layout will dance a little on the screen until the columns have been filled with their largest amounts of data. This is the result of the table layout being re-calculated as more data fills it. That being said, overall, this solution works great. It moved the pause from seconds to under half a second or less—making the page go from unbearable to usable on Microsoft’s latest browser offerings.

Because this was a lengthy presentation I have divided it into sections.

                                                            In this episode I talk about how I use Makefiles to ease the process of building complicated projects in Lilypond and HTML. You can use Makefiles to run any kinds of commands you want. It does not have to be building actual computer programs. In my case I use them to build musical scores and web pages. Keep in mind I'm not an expert on this, and I'm hoping I will make enough mistakes that it will prompt a series of follow-up episodes by people who actually know what they're talking about.

Written in a combination of LaTeX\n and Lilypond, this requires very complicated and long commands to build the workbook, and I found that the only way to do this project in a sane manner was to create a Makefile that would keep track of changes in the files and only rebuild when necessary. It also meant that the only commands I would have to type were very simple, because the long command line options were all stored in the Makefile.

This might be fascinating or it might be boring, but in either case I hope it inspires someone else to start uploading more shows. Incidentally, I recorded this whole thing on my phone, I’m doing these show notes on my phone, and am going to upload it from my phone as well, without adding the intro and outro music, showing just how easy it really is (as the saying goes).

                                                            \n

                                                            In April 2015 I suddenly found myself getting dizzy as I bent down – to the extent where I actually fell over at one point. I went to see a doctor but didn’t get a diagnosis.

                                                            \n

                                                            A medical student I know suggested it might be BPPV - Benign Paroxysmal Positional Vertigo, and with that in mind I researched it and found what turned out to be a cure.

                                                            \n

                                                            \n

                                                            The basic syntax is:

                                                            \n
                                                            awk [options] 'pattern {action}' file
                                                            \n

                                                            Here is a simple example file that we will be using, called file1.txt:

                                                            \n
                                                            name       color  amount\napple      red    4\nbanana     yellow 6\nstrawberry red    3\ngrape      purple 10\napple      green  8\nplum       purple 2\nkiwi       brown  4\npotato     brown  9\npineapple  yellow 5
                                                            \n

                                                            First command:

                                                            \n
                                                            awk '{print $2}' file1.txt
                                                            \n

                                                            As you can see, the “print” command will display the whatever follows. In this case we are showing the second column using “$2”. This is intuitive. To display all columns, use “$0”.

                                                            \n

                                                            This example will output:

                                                            \n
                                                            color\nred\nyellow\nred\npurple\ngreen\npurple\nbrown\nbrown\nyellow
                                                            \n

                                                            Second command:

                                                            \n
                                                            awk '$2=="yellow"{print $1}' file1.txt
                                                            \n

                                                            This will output:

                                                            \n
                                                            banana\npineapple
                                                            \n

                                                            As you can see, the command matches items in column 2 matching “yellow”, but prints column 1.

                                                            \n

                                                            Field separator

                                                            \n

                                                            By default, awk uses white space as the file separator. You can change this by using the -F option. For instance, file1.csv looks like this:

                                                            \n
                                                            name,color,amount\napple,red,4\nbanana,yellow,6\nstrawberry,red,3\ngrape,purple,10\napple,green,8\nplum,purple,2\nkiwi,brown,4\npotato,brown,9\npineapple,yellow,5
                                                            \n

                                                            A similar command as before:

                                                            \n
                                                            awk -F"," '$2=="yellow" {print $1}' file1.csv
                                                            \n

                                                            will still output:

                                                            \n
                                                            banana\npineapple
                                                            \n

                                                            Regular expressions work as well:

                                                            \n
                                                            awk '$2 ~ /p.+p/ {print $0}' file1.txt
                                                            \n

                                                            This returns:

                                                            \n
                                                            grape   purple  10\nplum    purple  2
                                                            \n

                                                            Numbers are interpreted automatically:

                                                            \n
                                                            awk '$3>5 {print $1, $2}' file1.txt
                                                            \n

                                                            Will output:

                                                            \n
                                                            name    color\nbanana  yellow\ngrape   purple\napple   green\npotato  brown
                                                            \n

                                                            Using output redirection, you can write your results to file. For example:

                                                            \n
                                                            awk -F, '$3>5 {print $1, $2}' file1.csv > output.txt
                                                            \n

                                                            This will output a file with the contents of the query.

                                                            \n

                                                            Here’s a cool trick! You can automatically split a file into multiple files grouped by column. For example, if I want to split file1.txt into multiple files by color, here is the command.

                                                            \n
                                                            awk '{print > $2".txt"}' file1.txt
                                                            \n

                                                            This will produce files named yellow.txt, red.txt, etc. In upcoming episodes, we will show how to improve the outputs.

                                                            Hello, this is Windigo, and Welcome to the another episode of apt spelunking! If you missed the first episode, then you probably missed the second episode as well. I assure you, they were fantastic; no need to go back and check.

                                                            \n

                                                            This series (and yes, it’s official now) is about finding uncommon packages that are buried in the Debian repos. It could very well be about finding packages in other repos, but no Arch, Fedora, Ubuntu or OpenSUSE users are smart or handsome enough to contribute an episode.

                                                            \n

                                                            In no particular order, here are a few more packages I’ve discovered.

                                                            \n

                                                            nodm

                                                            \n

                                                            nodm is a very small, very specific utility that is used to start an X session automatically.

                                                            \n

                                                            On Debian, you configure nodm with the configuration file located at /etc/defaults/nodm. You can specify whether or not nodm is enabled, which user to run as, and what x session to run.

                                                            \n

                                                            While hugely insecure, nodm is a great way to avoid the hassle of a full display manager like gdm or lightdm. It’s extremely lightweight, which is perfect for my Mini 9, and kicks things right into my custom i3 session.

                                                            cmus is a very comprehensive, console-based music player. cmus stands for “C* music player“.

                                                            I received cmus as a recommendation from chalkahlom (Gavin) while looking for a media player suitable for the Mini 9. It is a very light application (1.5M uncompressed), which suited my needs well.

                                                            \n

                                                            The interface of cmus is slightly strange, and may take some getting used to. It is broken up into seven “views”, which can be accessed using the number keys. The views are “Library”, “Sorted Library”, “Playlist”, “Play Queue”, “Browser”, “Filters”, and “Settings”.

                                                            \n

                                                            To be honest, I still haven’t given cmus a fair shake. It seems like an excellent music player, but I’m still unable to break away from the familiarity of audacious. I’m once again reaffirming my commitment to trying cmus out; it seems like a really good player, if given the time of day.

                                                            parecord

                                                            \n

                                                            Pulseaudio comes with a selection of very handy command-line utilities that can be used to play and record audio in various formats. The one I’d like to discuss is “parecord”.

                                                            \n

                                                            Ordinarily, I do all of my podcast recording with the arecord utility, which talks directly to ALSA. Last time I tried this, it very badly broke audacity when I tried to import the audio. I sounded like a chipmunk, and then audacity crashed.

                                                            \n

                                                            parecord is a nice alternative to arecord, because it also does encoding on the fly. There may be an ALSA equivalent that also encodes your audio as you’re recording, but I don’t know about it. At best, you’d have to pipe the output of arecord to avconv or a similar utility.

                                                            \n

                                                            Using parecord, I can specify the file format using the --file-format flag, and record directly to FLAC, which is what HPR prefers. Other formats are available, but I think FLAC is a good balance of quality and compression.

                                                            \n

                                                            If you prefer the raw recording style of arecord, there is a utility called parec which will record raw audio data, but it’s a bit outside of the scope of this podcast. Also, I don’t really know much about it.

                                                            \n
                                                            \n

                                                            I hope someone can find some use in the applications I’ve mentioned here. If you have some other packages that you find indispensable and/or useful, I’d love to hear about them in your very own episode.

Because two of the participants are gardeners we chatted about gardening.

                                                            \nFax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy.[1] Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black.\n

This is most useful on data that contains many such runs. Consider, for example, simple graphic images such as icons, line drawings, and animations. It is not useful with files that don't have many runs as it could greatly increase the file size.\n

RLE also refers to a little-used image format in Windows 3.x, with the extension rle, which is a Run Length Encoded Bitmap, used to compress the Windows 3.x startup screen.\n

                                                            I have recently been fortunate enough to give a presentation to two conferences, PyCon Australia and Kiwi Pycon, the Australian and New Zealand Python conferences, respectively. I'm not going to give a talk based around the presentation, as it's rather code heavy, and we know that doesn't translate well to an audio medium.

                                                            \n

                                                            Instead, what I wanted to do, was to talk a little bit about the presentation pipeline that I used to prepare this talk. The input is a plain text file, edited in Emacs, using a mode called Org mode. The intermediate form is a LaTeX file, using the document class Beamer which is designed for presentations that are going to be projected. Beamer is apparently the German word for digital projector. The final output form is a plain PDF.

                                                            \n

                                                            HPR isn't known for having many Emacs talks, so I should probably explain the idea of modes. Emacs has major modes and minor modes. For every document that you're editing there's one major mode, and any number of minor modes. So if I was editing a Python file for example, I would have the Python major mode which understands Python and can thus do Python specific things like Python code completion, and I would have a spell checker minor mode to check the spelling of comments, and another minor mode to automatically line wrap comment lines that are very long, and another minor mode to show what line number I'm currently editing, and another minor mode to blink the cursor and so on.

                                                            \n

                                                            The other topic that I haven't heard too much on is LaTeX. LaTex is the venerable typesetting solution for Unix based systems. LaTeX documents have a single document class, and then any number of packages. In the case of my presentation, the document class is Beamer, which sets up all the margins and fonts to be good for presentations. Some of the packages I'm using are the symbols package, for arrows and maths symbols, and several graphics packages so I can draw trees in my slides.

                                                            \n

                                                            I'm fairly comfortable with LaTeX, I could certainly write this presentation directly in LaTeX, but I think there are some advantages in using Org mode to generate my LaTeX instead.

                                                            \n

                                                            As the name suggests, Org mode is designed to be an organisational mode, helping you write TODO lists and organise documents. While the document is just a plain text document that you can read and write with any text editor, the Emacs Org mode understands its own mark up and provides an outlining mode, where you can hide and expand trees of bullet points. The basic layout of a set of slides for a presentation is a tree of bullet points, where the top level bullet points are slides, and the second level of bullet points are lists of information put into each slide.

                                                            \n

                                                            Another mark up that Org mode understands is that of code blocks, so that we can easily say ``this chunk of code is a Python block''. Org mode understands how to export this Python code block as a separate file, run it under Python, and can even insert the output of the program, or the result of a function, back into the original document as a code output block.

                                                            \n

                                                            The advantage of having just one file for my presentation, versus one file for my presentation and a separate file for each code block, is that the code examples in my presentation never get out of sync with the code that I'm actually running. This style of programming where the documentation is the primary document, and the code files are generated, secondary documents, is the inverse of the typical way of programming where the code documents are the primary documents, and documentation, the secondary documents, are automatically generated.

                                                            \n

                                                            This style of programming, where the primary document is documentation is called literate programming. The process of creating the documentation (the PDF in my case) is called weaving. The process of creating the code files is called tangling.

                                                            \n

                                                            I really like having just one file to generate one PDF presentation file, so I'm going to keep using this technique in the future.

                                                            \n

                                                            Now, I have to admit that my presentation is not completely literate, there are some bits of output in my presentation that are copied and pasted, rather than automatically gathered, so I've still got some work to do.

                                                            \n

                                                            Down to brass tacks. The conventional file name extension for Org mode files is dot org. The typical metadata you put in presentations are Author, Email, and Title. In mine I've also added Subtitle and Institute. Now, the interesting one here is Institute, for whatever reason, it's not a piece of metadata that Org mode knows about, but it's really easy to drop down into LaTeX and just use the LaTeX institute command directly.

                                                            \n

                                                            There's a metadata line that Org understands called Options, I request that my presentation has a table of contents, and that all the bullet points of level two become line items in that table of contents. Then I'm straight into the slides. Bullet points at the first level are converted to sections, bullet points at the second level are turned into slides, and anything deeper than that are turned into contents of that slide. I have many code blocks, and I use options that specify what file this code block is tangled to, and to leave the white space alone when the code block is exported, as white space is critical to Python. I also turn on an option that gets line numbers printed for the code blocks. In a couple of places where I want to highlight certain areas of the code, I add labels to the code, then outside the code block I can refer to the label, and LaTeX will replace this with the line number. I think I'd prefer to do this referencing with highlighting, or an arrow or something, but I'm not sure I can do that.

                                                            \n

                                                            Engineering is the process of dealing with tradeoffs to get something done, there are many trade offs when writing code to solve a problem, writing code for slides has quite a different set of tradeoffs, you want code to be easy to read, in terms of using long variable names, but you also need code blocks to contain as few lines as possible, so that you can use a large font size on the projector, and you also don't want to have to split an example across multiple slides if you can help it. I'm also of the view that syntax highlighting is a waste of time, it's just a pretty layer of obfuscation that the mind has to understand, then drop in order to actually see the code. This stance of mine was vindicated when several presenters with syntax highlighted code realised on the day that the projected code was impossible to read due to the low contrast projectors used in a reasonably well lit room.

                                                            \n

                                                            One feature that I would like to add is the ability to reveal new code. It's quite common to have a code block, reveal a problem with it, and display the same code block again, but with a minor change that fixes the previously explained problem. Ideally the old code and new code would be rendered differently, but I don't think that's an option right now. The other thing that I couldn't work out was how to run custom programs on my code blocks, I was wanting to run the Python unit test program, not the Python interpreter, and could not find a way to do that.

                                                            \n

                                                            There's a single command to run inside Emacs to create the output PDF, M-x org-beamer-export-as-pdf.

                                                            \n

                                                            So, overall, I'm very happy with this pipeline. It lets me have a primary document with code snippets, and it lets me have LaTeX snippets wherever I like. It's not perfect, but I'm hoping to find ways to improve it.

                                                            Remember our file:

                                                            Replace Grep

                                                            \n

                                                            As we saw in earlier episodes, we can use awk to filter for rows that match a pattern or text. If you know the grep command, you know that it does the same function, but has extended capabilities. For simple filter, you don't need to pipe grep outputs to awk. You can just filter in awk.

                                                            \n

                                                            Logical Operators

                                                            \n

                                                            You can use logical operators "and" and "or" represented as "&&" and "||", respectively. See example:

                                                            \n
                                                            $2 == "purple" && $3 < 5 {print $1}
                                                            \n

                                                            Here, we are selecting for color to to equal "purple" AND amount less than 5.

                                                            \n

                                                            Next command

                                                            \n

                                                            Say we want to flag every record in our file where the amount is greater than or equal to 8 with a '**'. Every record between 5 (inclusive) and 8, we want to flag with a '*'. We can use consecutive filter commands, but there affects will be additive. To remedy this, we can use the "next" command. This tells awk that after the action is taken, proceed to the next record. See the following example:

                                                            \n
                                                            NR == 1 {\n  print $0;\n  next;\n}\n\n$3 >= 8 {\n  printf "%s\\t%s\\n", $0, "**";\n  next;\n}\n\n$3 >= 5 {\n  printf "%s\\t%s\\n", $0, "*";\n  next;\n}\n\n$3 < 5 {\n  print $0;\n}
                                                            \n

                                                            End Command

                                                            \n

                                                            The "BEGIN" and "END" commands allow you to do actions before and after awk does its actions. For instance, sometimes we want to evaluate all records, then print the cumulative results. In this example, we pipe the output of the df command into awk. Our command is:

                                                            \n
                                                            df -l | awk -f end.awk
                                                            \n

                                                            Our awk file looks like this:

                                                            \n
                                                            $1 != "tmpfs" {\n    used += $3;\n    available += $4;\n}\n\nEND {\n    printf "%d GiB used\\n%d GiB available\\n", used/2^20, available/2^20;\n}
                                                            \n

                                                            Here, we are setting two variables, "used" and "available". We add the records in the respective columns all together, then we print the totals.

                                                            \n

                                                            In the next example, we create a distinct list of colors from our file:

                                                            \n
                                                            NR != 1 {\n    a[$2]++\n}\nEND {\n    for (b in a) {\n        print b\n    }\n}
                                                            \n

                                                            This is a more advanced script. The details of which, we will get into in future episodes.

                                                            \n

                                                            BEGIN command

                                                            \n

                                                            Like stated above, the begin command lets us print and set variables before the awk command starts. For instance, we can set the input and output field separators inside our awk file as follows:

                                                            \n
                                                            BEGIN {\n    FS=",";\n    OFS=",";\n    print "color,count";\n}\nNR != 1 {\n    a[$2]+=1;\n}\nEND {\n    for (b in a) {\n        print b, a[b]\n    }\n}
                                                            \n

                                                            In this example, we are finding the distinct count of colors in our csv file, and format the output in csv format as well. We will get into the details of how this script works in future episodes.

                                                            \n

                                                            For another example, instead of distinct count, we can get the sum of the amount column grouped by color:

                                                            \n
                                                            BEGIN {\n    FS=",";\n    OFS=",";\n    print "color,sum";\n}\nNR != 1 {\n    a[$2]+=$3;\n}\nEND {\n    for (b in a) {\n        print b, a[b]\n    }\n}
                                                            \n","hostid":300,"series":94,"explicit":0,"license":"CC-BY-SA","tags":"awk,bash,linux","version":0,"downloads":0,"valid":1}, {"id":2144,"date":"2016-10-20","title":"An Interview with All About Code at Manchester BarCamp","duration":479,"summary":"This is a follow up interview with Josh as he has been busy since I last interviewed him ","notes":"

                                                            "The bowline (/ˈboʊlɪn/ or /ˈboʊlaɪn/)[1] is an ancient and simple knot used to form a fixed loop at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes referred as King of the knots because of its importance. It is one of the four basic maritime knots (the other three are figure-eight knot, reef knot and clove hitch).

                                                            \n

                                                            The structure of the bowline is identical to that of the sheet bend, except the bowline forms a loop in one rope and the sheet bend joins two ropes. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots.[2]

                                                            \n

                                                            Although generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load, to slip when pulled sideways[3] and the bight portion of the knot to capsize in certain circumstances.[citation needed] To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications".

                                                              11. \n

                                                            I think the killer of these is #2, the rest are nitpicks or incorrect. And for addressing #2 there is the very interesting gitless report and project, which I'm guessing doesn't abandon git entirely, just reworks the UI, which does need rework. Not for people like me, who already learned the nooks and crannies and make productive use of several of what might be misfeatures, but to lower the threshold for people coming to our software projects and whatever other source code we are managing.

                                                            \n

                                                            This is the fourth episode of the series that Mr. Young and I are doing. These shows are now collected under the series title “Learning Awk”.

                                                            \n

                                                            Recap of the last episode

                                                            \n

                                                            Logical Operators

                                                            \n

                                                            We have seen the operators ‘&&’ (and) and ‘||’ (or). These are also called Boolean Operators. There is also one more operator ‘!’ (not) which we haven’t yet encountered. These operators allow the construction of Boolean expressions which may be quite complex.

                                                            \n

                                                            If you are used to programming you will expect these operators to have a precedence, just like operators in arithmetic do. We will deal with this subject in more detail later since it is relevant not only in patterns but also in other parts of an Awk program.

                                                            \n

                                                            The next statement

                                                            \n

                                                            We saw this statement in the last episode and learned that it causes the processing of the current input record to stop. No more patterns are tested against this record and no more actions in the current rule are executed. Note that “next” is a statement like “print”, and can only occur in the action part of a rule. It is also not permitted in BEGIN or END rules (more of which anon).

                                                            \n

                                                            The BEGIN and END rules

                                                            \n

                                                            The BEGIN and END elements are special patterns, which in conjunction with actions enclosed in curly brackets make up rules in the same sense that the ‘pattern {action}’ sequences we have seen so far are rules. As we saw in the last episode, BEGIN rules are run before the main ‘pattern {action}’ rules are processed and the input file is (or files are) read, whereas END rules run after the input files have been processed.

                                                            \n

                                                            It is permitted to write more than one BEGIN rule and more than one END rule. These are just concatenated together in the order they are encountered by Awk.

                                                            \n

                                                            Awk will complain if either BEGIN or END is not followed by an action since this is meaningless.

                                                            \n

                                                            Variables, arrays, loops, etc

                                                            \n

                                                            Learning a programming language is never a linear process, and sometimes reference is made to new features that have not yet been explained. A number of new features were mentioned in passing in the last episode, and we will look at these in more detail in this episode.

For some reason I couldn't find it at the time, even though it's clearly there, so I'm currently using the version from the Google Play Store. I hear that battery use may be an issue if you're independent from the evil GOOG.

                                                            Dutch Blitz was created by Werner Ernst George Muller, from\nPennsylvania, in the United States, in 1959. It is similar to the game\nNertz, which is played with standard playing cards. Nertz had been\naround since the 1940s. It isn’t totally clear to what extent Mr\nMuller was influenced by the game of Nertz. He was an optometrist and\nit is said that he thought the game might help his children learn\nabout colors and numbers.

                                                            The game has a theme that originates with the Pennsylvania Dutch\nculture, which was formed by early German immigrants to eastern\nPennsylvania in the United States. The symbols used on the cards are\nrepresentative of that culture, which tended to be agricultural and of\na conservative protestant Christian faith.

There is an extension pack that adds\n4 more decks, supporting 4 more players. Each deck has 40 cards made\nup of number cards from 1 through 10 in four different colors (suits):\nred, blue, green, and yellow. Additionally, the red and blue cards\nhave a picture of a boy and the green and yellow cards have a picture\nof a girl. The decks are differentiated from each other by a symbol on\nthe back side of each card. The four standard decks have the following\nsymbols: pump, buggy, plow, and bucket.

                                                              Post Piles - Three piles of cards to the left of the Blitz pile that\nare used by the player to help sort through cards during the game\nplay. These piles begin as 3 cards dealt out by the player before\ngame play. Cards can then be added to these piles in descending order\nand alternating “gender”. If one of the Post piles is cleared, the\nplayer may take a card off of their Blitz pile to start a new one.

                                                              Dutch Piles - During game play, players can start a Dutch pile when\nthey have a playable card with the number 1 on it. These piles are\nplaced in the middle of the table. The piles can then be built up,\nin sequential order and of matching color. Any player can play a\ncard on any Dutch pile.

When play\nstarts, all players begin playing at the same time as fast as they\ncan. When a player is able to clear their Blitz pile, they shout the\nword “Blitz” and all play must then stop. That is the end of the\nround.

Each player\ncounts the number of cards that they have played and then subtracts\ntwo times the number of cards left on their Blitz pile. That is their\nscore for the round.

                                                            \n

                                                            I managed to buy a Raspberry Pi Zero when they first came out in December 2015. This was not easy since they were very scarce. I also bought a first-generation case from Pimoroni and some 40-pin headers. With the Zero this header is not pre-installed and it’s necessary to solder it onto the Pi yourself.

                                                            \n

                                                            I have had various project ideas for this Pi Zero, but had not decided on one until recently. Within the last month or two Pimoroni produced a device called the Blinkt! which has eight APA102 RGB LEDs and attaches to the GPIO header. This costs £5, just a little more than the Zero itself.

                                                            \n

                                                            My plan was to combine the two and turn them into a status indicator for various things going on that needed my attention.

                                                            1. Make sure you have console access to the linux VM

                                                            4. Reboot

                                                            6. The grub2 prompt has tab completion which can be helpful.

                                                            \n

I was stating the fact that they are a very successful company DESPITE a lot of Tech writers and podcasters out here stating they aren't. You can argue the privacy points all you want but the fact is all I was stating was they are successful.

                                                            Regular Expressions in AWK

                                                            \n

                                                            The syntax for using regular expressions to match lines in AWK is as follows:

                                                            \n
                                                            word ~ /match/
                                                            \n

                                                            Or for not matching, use the following:

                                                            \n
                                                            word !~ /match/
                                                            \n

                                                            Remember the following file from the previous episodes:

                                                            \n
                                                            name       color  amount\napple      red    4\nbanana     yellow 6\nstrawberry red    3\ngrape      purple 10\napple      green  8\nplum       purple 2\nkiwi       brown  4\npotato     brown  9\npineapple  yellow 5
                                                            \n

                                                            We can run the following command:

                                                            \n
                                                            $1 ~ /p[elu]/ {print $0}
                                                            \n

                                                            We will get the following output:

                                                            \n
                                                            apple      red    4\ngrape      purple 10\napple      green  8\nplum       purple 2\npineapple  yellow 5
                                                            \n

                                                            In another example:

                                                            \n
                                                            $2 ~ /e{2}/ {print $0}
                                                            \n

                                                            Will produce the output:

                                                            Example:

                                                            \n

                                                            The output is:

                                                            Another example:

                                                            \n

                                                            \n

                                                            Here's the text from IRC:

                                                            China doesn't want Taiwan to be independent because that would be a loss of prestige to China.

                                                            \n

                                                            There are no technical details about it, it's all about symbolism.

                                                            \n

                                                            The China thing is a really interesting thing to unpack. First of all, if you ask the traditional ruling party on Taiwan, the KMT or GMD (Guo Min Dang), there is no country called Taiwan. The KMT and the CCP (Chinese Communist Party) agree that there is only one China and Taiwan is simply a province of that China. Where they disagree is whether the true government of the whole is in Beijing or in Taipei. (fun fact: the official capital of the Republic of China (Taiwan) is Nanjing, which is not under ROC control)

                                                            \n

                                                            Also, some de-facto parts of India and all of Mongolia is officially part of the ROC, according to their Constitution.

                                                            If you fly from Beijing, there are domestic flights and \"international flights and domestic flights to Hong Kong, Macau and Taiwan\".

                                                            \n

                                                            So the US and UN stance since 1972 is \"there is one China, and its government is in Beijing\". But at the same time US is giving military support to Taipei, which according to Beijing is an unruly province.

                                                            \n

                                                            As long as the status quo holds – that Taipei claims to rule all of China and Beijing claims to rule all of China and no outsider that matters challenges that – China (both of them!) is happy. It works, there are extended business relations between the two jurisdictions (most of the electronics made in China are made in factories owned by Taiwanese companies)

                                                            \n

                                                            Both the CCP and the KMT hope that in the long term, this can gradually creep toward a unification of China. If Taiwan would declare independence, that would mean war.

                                                            \n

                                                            Now, the current ruling party, the DPP (Democratic Progressive Party) officially support driving toward a Taiwanese rather than a Chinese national identity, and at some point independence. They are being very careful about it though, because they are also aware of how Beijing would react if they went out and did it. Also, while they do control the majority of the Legislative Yuan, there is a significant minority in Taiwan that adhere to a Chinese identity, don't want to upset China, and don't want formal independence. The current quirky situation works, and barriers have been coming down over the years. Relations are abnormal yet normal. On the rhetorical level it's all messed up, in practice you can fly between the island and the mainland, you can conduct business and send post, etc.

                                                            \n

                                                            When ROC (Republic of China, \"Taiwan\") and PRC (People's Republic of China, \"Mainland China\") representatives meet, there are no embassies or consulates involved, because neither acknowledges the other as a country. Neither President will call the other \"President\", because that would imply they represent a country, rather than a rebel faction inside what the other side considers China.

                                                            \n

                                                            So when Trump goes on Twitter and says \"The President of Taiwan CALLED ME today to wish me congratulations on winning the Presidency. Thank you!\" that's a huge scandal in the eyes of Beijing. There is no President of Taiwan, and to imply so is to imply that Taiwan is a country and should be independent.

                                                            \n

                                                            That's as short as I can make it, but that's the low-down on what's up in the Taiwan Strait.

                                                            \nAs we all know the word Free has two meanings in the English language. Free of cost and Free from Freedom. So we get the expression \"free as in Beer\" and \"Free as in Freedom\" - or Free with a lower or upper F. Having disambiguity in a computer program is bad. So let's translate that problem to computer languages, and I'm going to deliberately pick the C language. So for example were the word \"exit\" (which is a function), and you wanted to use it as a variable.\n

                                                            \n

                                                            \nset exit = 1;\n

                                                            \n

                                                            \nThis leads to problems as the computer can't tell if the references to \"exit\" the function or is it the \"variable\".\n

                                                            \n

                                                            \nFor that reason the \"The GNU C Library Reference Manual\" makes it clear that this is not allowed\n

                                                            \n The names of all library types, macros, variables and functions that come from the ISO C standard are reserved unconditionally; your program may not redefine these names. All other library names are reserved if your program explicitly includes the header file that defines or declares them. There are several reasons for these restrictions:\n

                                                            \n

                                                            \n Other people reading your code could get very confused if you were using a function named \"exit\" to do something completely different from what the standard \"exit\" function does, for example. Preventing this situation helps to make your programs easier to understand and contributes to modularity and maintainability.\n

                                                            \n

                                                            \n It avoids the possibility of a user accidentally redefining a library function that is called by other library functions. If redefinition were allowed, those other functions would not work properly.\n

                                                              • \n
                                                            • Buffer overflows, where there is too much information to take in.\n

                                                              • \n
                                                            \n\n

                                                            \nNow you can get around the problem by prefixing the variable name with a name space, which is very common in XML.\n

                                                            \n

                                                            \nset my:exit = 1;\n

                                                            \n

                                                            \nHowever that's cumbersome and causes extra cycles to be expended, or abnormal termination of the program. Not many cycles but a few and it adds up over time. The more you use it the more wastage occurs. When you have two Bob's working in a company. You always need to specify if it's \"Bob in Accounting\" or \"Bob in Sales\".\n

                                                            \n

                                                            \nIt is often pointed out that this is not an issue in other languages, for example Dutch has \"Vrij\" for freedom and \"Gratis\" for without cost. However the FSF is a US organisation, in a English speaking area. So we should focus on the fact that the English compiler should have rejected at use of \"Free\" when it was first proposed because it was obviously disambiguous.\n

Not that there is probably anything we can do about it now but if this bugs you then go over to the FSF and donate. If it doesn't bug you then donate. If you could care less, or indeed if you couldn't care less then also donate.\n

I skipped around in it for QA reasons (audio sync) and I found that I wanted to listen to it again myself, so if your interests are anything like mine, I think it will be able to hold your attention. We had great fun recording it, and now that I've got it out of the gate, maybe I won't be ashamed to ask Chris to record another one about one of the many topics that came up during this show.

That time, I was able to fix it by spraying contact cleaner on it, but this time that didn't work. I ordered a new part. In this episode I talk while I replace the part and I also talk about the nifty diagnostic tool that I used to get the trouble code and how it sends the information to your smartphone.

                                                            In high school, even though I went to a Grammar School, all boys attended mandatory lessons on metalwork and woodwork. We learnt how to use hand tools and some power tools, make joints in wood, we also learnt to do basic metal work like soldering and brazing, and so forth.

                                                            \n

                                                            Learning this stuff at school was great but I have used the woodworking techniques more than the metalwork - other than soldering.

                                                            \n

                                                            I stopped watching TV in 2013, preferring reading and listening to podcasts. In recent times I have subscribed to a number of YouTube channels which share woodworking and metalworking techniques and projects. In general these people are Makers and Artists who can turn their hands to many skills. I thought I would share some of my favourites via HPR.

                                                            You can share your Calibre ebook library by running the calibre-server daemon, either from your desktop machine or on a server that is available on your local network. (Or, if you have it set up that way, it can be outward-facing to the wide world.)

                                                            \n\n

                                                            To share your library from the desktop Calibre application, choose Connect/share from the menu at the top of the window, then choose Start Content Server. Make a note of the IP address and port, and then you can use other devices on your network to access the library at that address. Normally I use the \"Get Books\" function of the Marvin ebook app on my iPad, or else the \"Experimental Browser\" on my Kindle and download the books directly to the devices. On my Android phone, I use the Chrome browser and then long press on the link to an Epub file, choose to save to device, and then open it using FBreader.

                                                            To share the library from your GNU/Linux server, you'll have to install Calibre on the server and then put a copy of your ebook Library on the server as well. To start and stop the server daemon, you need to put a service startup script in the /etc/init.d directory with all of the other system startup scripts. An example is given below—fill in with the appropriate paths and user data for your setup. (See the calibre-server user manual for a full list of options and their descriptions.) When the script is in place and has executable permissions, you start and stop the service as follows (as root):

                                                            I have been listening to podcasts for many years. I started in 2005, when I bought my first MP3 player.

                                                            \n

                                                            Various podcast downloaders (or podcatchers) have existed over this time, some of which I have tried. Now I use a script based on Bashpodder, which I have built to meet my needs. I also use a database to hold details of the feeds I subscribe to, what episodes have been downloaded, what is on a player to be listened to and what can be deleted. I have written many scripts (in Bash, Perl and Python) to manage all of this, and I will be describing the overall workflow in this episode without going into too much detail.

While I'm talking about this process, I also install new LED brake light bulbs on our Honda CR-V. I almost forgot to talk about the necessity of installing resistors to handle the problem of hyperflashing with the blinker lights.

                                                            I paid for one Omega2 Plus Kickstarter pledge. Later, as most do, the project offers upgrades. My pack was for one Omega2 plus, an OLED module, and the expansion board. After pledging I then added on another Omega2, a GPS module and a mini expansion board. Review wise, this is a good inexpensive IOT kit for any beginner. Someone that is more advanced can get into Arduino, or ESP8266 with microPython.

                                                            We don't manage to make a successful contact but we do pick up the bird. One person toward the end tried to pull us out of the noise but there were simply too many people utilizing the satellite for us to make contact. Part of that may have been my Doppler shift settings.

Once you have an account you have downloading access to the apps. Most of these apps are free but most premium service require a monthly fee which can be paid through Roku or the streaming service.

It is functionally very similar to the widely used Dropbox, with the primary functional difference being that Nextcloud is free and open-source, and thereby allowing anyone to install and operate it without charge on a private server. In contrast to proprietary services like Dropbox, the open architecture allows adding additional functionality to the server in form of so-called applications.\n

This is a longer process than installing a pre-compiled Linux distribution. The advantages to this method are a compact, flexible and secure system and a greater understanding of the internal workings of the Linux-based operating systems.\n

                                                            Regular expressions

                                                            \n

                                                            In the last episode we saw regular expressions in the ‘pattern’ part of a ‘pattern {action}’ sequence. Such a sequence is called a ‘RULE’, (as we have seen in earlier episodes).

                                                            \n
                                                            $1 ~ /p[elu]/ {print $0}
                                                            \n

                                                            Meaning: If field 1 contains a ‘p’ followed by one of ‘e’, ‘l’ or ‘u’ print the whole line.

                                                            \n
                                                            $2 ~ /e{2}/ {print $0}
                                                            \n

                                                            Meaning: If field 2 contains two instances of letter ‘e’ in sequence, print the whole line.

                                                            \n

                                                            It is usual to enclose the regular expression in slashes, which make it a regexp constant.

                                                            \n

                                                            We had a look at many of the operators used in regular expressions in episode 5. Unfortunately, some small errors crept into the list of operators mentioned in that episode. These are incorrect:

                                                            \n
                                                              \n
                                                            • \\A (beginning of a string)
                                                              • \n
                                                            • \\z (end of a string)
                                                              • \n
                                                            • \\b (on a word boundary)
                                                              • \n
                                                            \n

                                                            The first two operators exist, in languages like Perl and Ruby, but not in GNU Awk.

                                                            \n

                                                            For the ‘\\b’ sequence the GNU manual says:

                                                            \n
                                                            \n

                                                            In other GNU software, the word-boundary operator is ‘\\b’. However, that conflicts with the awk language’s definition of ‘\\b’ as backspace, so gawk uses a different letter. An alternative method would have been to require two backslashes in the GNU operators, but this was deemed too confusing. The current method of using ‘\\y’ for the GNU ‘\\b’ appears to be the lesser of two evils.

                                                            \n
                                                            \n

                                                            The corrected list of operators is discussed later in this episode.

                                                            After a short introduction of the hosts, we start discussing the question that came up on the mailinglist:

                                                            \n

                                                            How do you get started at all? How do you get the license to participate in amateur radio?

                                                            \n

                                                            Probably the amateur radio organisation in your country will provide the essential information required for obtaining an amateur radio license. Start looking at the International Amateur Radio Union at https://www.iaru.org and track down your country. From there you can search for information about your local area and local groups. In the US, look for the ARRL at https://www.arrl.org.

                                                            \n

                                                            If you do not chose to get involved with the local club before taking the test to get the license, we suggest you do so after that. Local events and clubs can provide the insight into the vast possibilities amateur radio has to offer. This will allow you to chose much better, where your personal interests are and where to start. Radio "nets", are mentioned as a good starting point to actually get "on the air" and to overcome any possible shyness.

                                                            • VFO: Variable Frequency Oscillator. The thing behind the main tuning dial to adjust the frequency, an important building block of radio equipment. In modern gear the VFO-mode is the mode where you can continuously change the frequency in certain increments, as opposed to memory mode, where you normally select from a set of fixed frequencies previously stored.

                                                            • VHF: Very High Frequency. Generally this references the frequency range 30 Mhz to 300 MHz. In the context of a radio user, it normally means the sub range in there, that is assigned to the specific use.

                                                            • UHF: Ultra High Frequency. 300 MHz to 3 GHz
                                                              • \n
                                                            • HF: High Frequency. Range 3 MHz to 30 MHz. Also referenced to as "short wave" frequencies. Several amateur radio "bands" are spread out in that frequency range.
                                                              • \n

                                                            We often reference frequency ranges by wavelength. E.g. the "20m band", which is the frequency allocation for amateur radio at 14 MHz. The connection is: Wavelength = c / frequency, with c being the speed of light. A rule of thumb is: Wavelength [m] = 300 / frequency [MHz]

                                                            We went on describing a bit where our personal interests in amateur radio are.

                                                            \n

                                                            Our combined interests cover all the way from Morse code over voice communication to digital modes and "foxhunt" (the radio sport of Amateur Radio Direction Finding). Note that there are many other facets to amateur radio. Even our combined interests are just a small segment of the possible activities within the avocation.

                                                            \n

                                                            We talk about getting started with just listening to amateur radio traffic on the short wave frequencies.

                                                            \n

                                                            Why do you need a license, why not just do it?

                                                            \n

                                                            First, without a license, it is ILLEGAL.

                                                            \n

                                                            Law makers have acknowledged that one important goal of amateur radio is education and experimentation. We are allowed to modify equipment or even build it completely from scratch and operate it legally on the assigned frequencies. This is a unique privilege that sets amateur radio apart from any other radio users which have to use certified equipment.

                                                            \n

                                                            We give some amateur related podcast recommendations, among those: Linux in the ham shack (https://lhspodcast.info) and HamRadio 360 (https://hamradio360.com).

                                                            We have been collecting and storing tags for new HPR shows for a while now with the intention of eventually offering a search interface. In addition, a number of contributors, including myself have been adding tags (and summaries), to shows that do not have them, since August 2015. There is still a way to go, but we’re making progress. At the time of writing (2017-01-31) 56.29% (1248) of all HPR shows (2217) have tags.

                                                            \n

                                                            In recent times the way in which we should use these tags has been discussed. In show 2035 on 2016-05-20 droops suggested:

                                                            The website, which is a lot of work, needs to have related shows listed on each individual show’s page. This will take a tag system and someone to tag all of the almost uncountable previous episodes.

                                                            This episode begins a discussion about some of the ways that tags can be stored, managed and accessed efficiently in the HPR database.

                                                            \n

                                                            I started planning a show about this subject in the summer of 2016, and the amount of information I have accumulated has grown since then. There is now quite a lot, so I am going to split what was originally going to be one show into three.

                                                            \n

                                                            The subject becomes quite technical in the later shows, discussing database design techniques, and all three of the shows contain examples of database queries and scripts. If you are not interested in this subject than feel free to skip past. However, you might find this first episode more palatable, and any thoughts you might have on the subject would be appreciated.

Current shows are archived to the Internet Archive (archive.org) within a few days of appearing in the main feed, and older shows are gradually being archived this way with the intention of eventually storing everything there.

                                                            In the earlier days the frequency of show release was not the predictable 5 per week, every weekday, that it is now. There were gaps, sometimes of several days, and occasionally shows came out on the weekend. Stability was achieved in October 2012 and there have been no gaps since then!

The number of episodes and hosts will be greater when the episodes from “Today With A Techie” are incorporated into the archive.

                                                            This net book came with a 8Gig SSD installed and a 32bit 1.6G atom processor and many modern Linux spins are just too big for the hardware.

                                                            \n

                                                            However Watt OS came to the rescue and installed on the Netbook without issue.

                                                            I plan to give it a go on a Lenovo x61 shortly and will let you know how that works out, my thought is it will fly on that hardware.

                                                            In the first show we looked at why we need tags, and examined the advantages and disadvantages of the present system of storage. We considered the drawbacks of this design when searching the tags.

                                                            \n

                                                            Then in the second show we looked at a simple way of making a tags table and how to query it in order to fulfil the requirements defined in the first show.

                                                            So we had this server.

                                                            \n

                                                            As all servers are wont to do, this one had run successfully for a number of years. Everything worked perfectly until it didn’t.

                                                            \n

                                                            It ran, to my knowledge, only Hyper-V Server on its system drive, and had a second set of drives for hosting the VM that ran Microsoft Deployment Toolkit to service our depot. Our depot was on its own physical network, sharing with production only an ISP demarc.

                                                            \n

                                                            I had long since abandoned the depot and its trappings, thinking it someone else’s domain, thinking my time better spent on client systems, thinking that I didn’t need to know what happened in the oft-ignored part of our operation. I assumed that it was set up properly since it had been so stable for so many years. But you know the old saying:

                                                            \n

                                                            When you make assumptions you make an ass out of you and muptions.

                                                            \n

                                                            The Problem.

                                                            \n

                                                            Our monitoring systems reports the two depot servers offline, both the hypervisor and its virtual. I sent our depot technician to take a look. They come back online and he tells me that it needed to be rebooted. Having divested myself of giving a damn about the depot, I barely found the energy to shrug.

                                                            \n

                                                            Then it happened again. I again sent the technician and promptly got wrapped up in some client-facing issue. I forgot about the servers until:

                                                            \n

                                                            They went offline a third time. I didn’t have to tell my depot tech; he was watching the same feed as I. He rummaged a bit and came back with a story of defeat and virtual disks not being found.

                                                            \n

                                                            “The server won’t boot because the Virtual disk can’t be found” he said.

                                                            \n

                                                            “Ok, so you mean the virtual won’t come up, but what about the physical?” I replied.

                                                            \n

                                                            “No, that’s what I mean. It won’t get past BIOS. It’s complaining of a virtual drive not being found.”

                                                            \n

                                                            “Sounds bogus, let’s look.”

                                                            \n

                                                            He was not wrong; that is what the screen said. And what it meant was RAID failure. I slid off the front of the server case and sure enough, one of the drives had popped.

                                                            \n

                                                            Oh, did I mention? No backups.

                                                            \n

                                                            The Rabbit Hole.

                                                            \n

                                                            Drives pop sometimes, ain’t no thing. We build systems to be resilient. You slap a fresh one in there and it starts re-silvering and you get on with your day. Not this time, gentle reader.

                                                            \n

                                                            While digging through the RAID controller, I found, to my amazement, horror, and utter confusion, that whatever chucklefuck set up this server put the two system drives in a RAID 0. As I stared at the screen and at the blinking amber drive light, all that could pass my lips was a quiet “Oh my god, why?”

                                                            \n

                                                            In this scenario, I didn’t see any way forward, but through. So far, it had been demonstrated that the bad drive would behave for about 2 hours, then throw a fit. I shut down the server and took some time to think about how to proceed. In that time, I re-discovered some of the things the virtual machine was serving.

                                                            \n

                                                            Things like: MDT, DNS, DHCP, PXE boot, but most importantly: the lone DC for depot.local (MDT needs a domain). Oh, and it was the only machine that was set up to manage the hypervisor through the Hyper-V console and Server Manager.

                                                            \n

                                                            GREAT.

                                                            Compounding the issue, the virtual was not stored on the separate set of RAID 1 disks in this server as I had assumed. It was stored on the system drive. Oh joy, oh rapture.

                                                            \n

                                                            My new mission: Rescue that virtual.

                                                            \n

                                                            The Struggle.

                                                            \n

                                                            First things first. I assume I’ll only have one chance to rescue this data before this drive bites the dust for good. I plug in the VGA and keyboard. Take a deep breath.

                                                            \n

                                                            I turn on the server.

                                                            \n

                                                            It fails to boot into the operating system. “Come on, you little shit.” Take out the drive and put it back in. Success. We boot into the OS and I’m presented with a log on screen. Password.

                                                            \n

                                                            There are no logon servers available to process your request.

                                                            \n

                                                            Shit, that’s right. The virtual is the only DC. K, local admin it is. Login successful. Presented with a command like and SConfig. Grab the terminal and start poking about. cd to C: and dir. Find a folder named VMs. Bingo. Started copying the VHDX to the RAID 1 set.

                                                            \n
                                                            cp “C:\\vms\\Hyper-V Replica\\Virtual hard disks\\{guid}\\{guid}.vhdx” E:\\
                                                            \n

                                                            The server moves the data at a respectful 700Mbps, considering its current degraded state. It eventually finished the transfer after about 10 agonizing minutes. Shut down the physical to preserve the bad drive.

                                                            \n

                                                            We are out of the woods, but it’s still a long way to Gramma’s house.

                                                            \n

                                                            I have a plan. Now that I have the VHDX, and since we clearly need a replica server, I’ll push my luck. I’ll build a new server and see if I can replicate the virtual. I happen to have a disused server sitting right next to the bad server. It’s admittedly dissimilar hardware, but shouldn’t be a problem. I don’t know why it’s lying dormant or what it was used for in the days of yore, but it’s mine now. Eminent domain.

                                                            \n

                                                            And here is the story of how it took me 4 hours to install an OS that usually takes 3 minutes.

                                                            \n

                                                            We need to load up Hyper-V 2012 on this “new” server first.

                                                            \n

                                                            As is standard practice, I disconnect all but one drive from the mobo. I do this because sometimes the Windows installer decides that the “SYSTEM” partition belongs on a different drive from the C partition and it makes me cry. I used rufus (what a fantastic little utility, really. I need to donate to that guy) to make a HV 2012 boot disk from ISO.

                                                            \n

                                                            You know how it takes a few times to get a USB to go into it’s slot correctly? Not me. I whipped that bad mamma-jamma like a shuriken from 30 feet away and it slid perfectly into the front of the server. Fireworks, 100 doves, the works.

                                                            \n

                                                            Boot it, get to the installer part where it asks you upon which drive you wish to install it. Boom, error:

                                                            \n

                                                            Setup was unable to create a new system partition or locate an existing system partition.

                                                            \n

                                                            Weird. Sounds like a problem with the disk, right? Open up diskpart, clean it, format, create partition, assign it a letter. No go. Try a different drive? Nope. Disconnect the cd drive maybe. No dice. Connect all the drives and try each one. Nada. Boot up into Ubuntu and use GParted to re-do what I did in diskpart. Zilch. Re-create the install media. Goose egg. Try the back USB ports. I’m running out of ways to say no, but in essence, nothing was making this error go away.

                                                            \n

                                                            Screw it. Maybe this is why this server was sitting unused? Maybe it’s a bad mobo or something and frankly, I don’t care. Part out the drives and junk it.

                                                            \n

                                                            We happen to have a literal pile of servers to pick from, so I grab the one on top because it’s the most similar to the bad server and because you must be out your damned mind if you think I’m digging through that mound of junk. This’ll do nicely.

                                                            \n

                                                            Remember how I said I didn’t want to have anything to do with the depot? I still don’t. I want this new server to be unkillable, may he reign for a thousand generations. So, I may have gone a little overboard with the RAID setup for one simple hypervisor, which is going to be backed up and replicated.

                                                            \n

                                                            That there is a 1TB RAID 1 with a hotspare and a 500ish GB RAID 5 with a hotspare. I never want to hear from this server again.

                                                            \n

                                                            OK, so we start the Windows server install and:

                                                            \n

                                                            THE SAME ERROR.

                                                            \n

                                                            No way. I have done this dozens of times, this is insane. I have used this exact same USB drive to do it! I can use it on an ancient spare laptop and go through the install perfectly fine. I have dug through pages of posts on forums and tried every last solution suggested except one. I find, on page 3 (!) of Google, someone say that it only failed for them when they used a USB 3.0 drive to install. I look at the end of my USB install media, see blue, then see red. NO. WAY.

                                                            \n

                                                            So I hunt around for a USB 2.0 drive. Takes me a few minutes, but we had one holding up the leg of a table. Rufus took a bit longer this time. When the drive was cooked, I gingerly placed it in the receptacle and crossed my fingers. If this didn’t work, then I was all out of ideas. No clue.

                                                            \n

                                                            It worked. I could not believe it. USB 3.0. Why, Windows, WHY?

                                                            \n

                                                            \n

                                                            Creating a new domain is a pain in the ass. I considered a number of possibilities, but now that I had the re-install of this server figured out, I figured let’s go nuts and join the new hypervisor to the old domain depot.local. If you’ll remember from 6 years ago when I started telling you this story, the sole virtual server performed DCHP, DNS, and DC functions.

                                                            \n

                                                            I powered up the bad physical server. It complained, but complied. Started the virtual, no issue. Waited a few minutes, then joined the shiny new server to the domain depot.local. From there, with the DC up and running it was a simple matter of using the Hyper-V console to set up replication. After about an hour of pacing back and forth like I was awaiting the birth of my first child, the virtual made it and was failed over successfully.

                                                            \n

                                                            There were a few more issues to resolve, like the DNS server having the wrong IPs for just about everything even though they have been using statics for years, DHCP not responding on port 4011 for MDT for PXE Boot, DHCP being handed out by the virtual AND by the router on the same subnet (?!?!), and the DNS server refusing to connect over the HyperV vSwitch, but now at least I don’t have a knot in my stomach. I don’t know how this environment ever worked like this. What a mess to clean up.

                                                            \n

                                                            I ripped the bad half of the RAID 0 out of the server like a man possessed. I nailed it to the wall behind my desk. There is a sign under it that reads: “RAID 0 is not RAID. If you use RAID 0 on anything, I will throw this hard drive at your head. I have good aim. It will probably hit your mouth.”

                                                            As we saw in the last episode 2045 (and others in this sub-series) there are eight types of expansion applied to the command line in the following order:

                                                            This is the last topic in the (sub-) series about expansion in Bash. However, when writing the notes for this episode it became apparent that there was too much to fit into a single HPR episode. Consequently I have made it into two.

                                                            \n

                                                            In this episode we will look at simple pathname expansion and some of the ways in which its behaviour can be controlled. In the next episode we’ll finish by looking at extended pattern matching. Both are included in the “Manual Page Extracts” section at the end of the long notes.

                                                            Hello HPR, a few episodes ago I talked of using the Lenovo X61s with Watt OS and said I would report back after a possible upgrade to the laptop with and SSD replacement for the hard drive.

                                                            \n

                                                            Well I duly ordered and received a Drevo 120 Gig SSD from ebay. These are about £40 each so make a cheap upgrade to an older laptops spinning disc see review here:

                                                            \n

                                                            https://www.enostech.com/drevo-x1-240gb-ssd-review/

                                                            \n

                                                            after installing the PC with WattOS while it did everything you would need of an OS and was absolutely fine on the X61s I was a bit disillusioned with the amount of configuration needed to get all the software I needed working, definitely not New user friendly.

                                                            \n

                                                            Looking at other lite Linux distributions I came upon Linux Lite

                                                            \n

                                                            https://www.linuxliteos.com/

                                                            \n

                                                            and decided that this might be a better choice as it says it is aimed at new users, and being based on Ubuntu was a familiar beast. ISO was downloaded and duly installed on the X61s and as soon as all the updates were completed I looked at the installed software and it was more comprehensive but not at the expense of still being lightweight.

                                                            \n

                                                            At first Boot it takes about 300mb of ram and even with the word processor and Firefox in use Ram usage was only about 700mb.

                                                            \n

                                                            Audacity after install worked out of the box, and I've already recorded and uploaded another show for HPR using the X61s and all went flawlessly. With the new SSD I am getting close to 5 hours of use from the 8 cell 63W battery installed on the PC and while I recognize the X61s being over 10 years old is not going to meet the needs of a power user, its fully capable of being an everyday laptop for basic office tasks, some light audio editing, and even photo editing in GIMP. I was able to edit and process a 10mb .jpg image without any issues and exporting the final image took seconds.

                                                            \n

                                                            I was fairly happy with the X61s performance with the 80Gig spinner it came with, but the addition of an SSD has both improved performance and battery life to the extent that I would happily take it on the road as my only PC. Actually for the porpoise of writing this review I've lived with it as my main PC for almost 2 weeks and have not really missed its big brother the X230i i3 laptop I also have. In fact I was going to record a show using that and found that as it has a composite Audio jack, and my head set requires separate mic and headphone sockets I wasn't able to, so one up to the X61s there.

                                                            \n

                                                            Conclusion, if you have a couple of kids and you're looking for a laptop for them to do homework, watch Utube, and surf the web (parental controls enabled) then I would look no further. And if they get broken by said kids you've not lost a bundle of dosh.

The supply voltage in the fault condition could be observed with an oscilloscope to completely collapse when load is turned on. Both facts are illustrated in the image below.

                                                            First off a disclaimer: anything I say here is my experience and is in no way intended as advice to anyone, everyone who experiences or is at risk of a stroke is different and you must make your own lifestyle choices based on professional advice.

                                                            \n

                                                            That clear lets get on with my show. On the 2nd February 2017 I had a Stroke, it came completely without warning. I was out with my wife, just about to start a Bridge class we were attending. I sat down at the table and just after sitting down was blasted with what I thought was White Noise from faulty hearing aids. After quickly removing them without any effect I thought I was having a sudden severe migraine, which I have from time to time. However I was unable to communicate what was happening and after several minutes my wife wrote on a paper the words “Home” and “Hospital” and I pointed to hospital. An Emergency ambulance was duly called and I was transferred to the local Emergency Department. Several hours later in the early hours of the next morning they admitted me, still not sure what had happened. It was only after a scan that afternoon that they concluded that I had had a Stroke.

                                                            \n

                                                            I was seen by a consultant that evening who confirmed this and as I still had residual problems on my right side concluded that it was a stroke, and not a TIA (Transient Ischaemic Attack) or a mini stroke as it is sometimes called. I spent the next 12 days in hospital having further tests, including another scan, an MRI as opposed to the previous CT scan I had had on admission. After seeing the results of this scan the Consultant was amazed that I was not more severely affected, in other cases of the type of stroke I suffered the physical and cognitive damage is much more severe. It was looking like I had thankfully, dodged a bullet.

                                                            \n

                                                            That is not to say there were no effects. My right side was effected and the fine motor control was damaged. Coordination in using my right hand and arm were initially difficult as was writing (I am predominantly right handed). Also my mouth felt like I was wearing someone’s false teeth, even though I have all my own. However the main effect has been fatigue, initially severe, but as I write this 6 weeks later this is starting to improve, although I still tire after 2-3 hours doing things that I could have done all day previously. I also still have a little feeling of weakness in my right hand and arm and writing is still an issue, thankfully most of my writing is done on a keyboard.

                                                            \n

                                                            So what caused it I hear you yelling, well the truth is they don’t know. The most serious risks are to people that Drink alcohol excessively, Smoke and have a high fat diet. Also those over weight particularly the obese, and people with diabetes are high risk. Another major risk factor is genetic, and I remembered afterwards that my Grandfather and an Uncle had major strokes that ultimately led to their deaths. Also stress and high blood pressure can be a factor.

                                                            \n

                                                            I don’t drink or smoke and have been a vegetarian for many years, also my blood pressure is checked regularly and was always seen as within normal range. However I was at the time of the stroke 21lb over weight, but even before it happened I had lost 7lb. Since the stroke the blood tests also show I am pre-diabetic so I need to increase my exercise (again something I had started to do), and alter my diet to reduce my blood sugars. Not major issues as I had started to attend a gym and walk more as part of the weight loss plan, and I actually prefer healthy food, and now have a reason to say to people when I’m in company why I eat what and the way I do.

                                                            \n

                                                            The main effect for me has been the restriction on my mobility as the Consultant will not let me drive until 3 months post discharge (14th May), which means I have to rely on others or get public transport, this is not the problem but having to walk from transport stops to where I’m going is due to the fatigue. Roll on May 14th.

                                                            \n

                                                            I thought I would record this show as a bit of a warning, and for listeners to realise that a Stroke can and does happen to anyone. On a positive note there is life after stroke and even for those who are more seriously disabled by a stroke many can and do recover most if not all the function they had before hand.

                                                            \n

                                                            As you have probably gathered by now if you have listened to my other shows I am a big fan of older Lenovo Laptops. My main Lenovo is an X230i i3 with a 2.5G cpu and 8Gig of Ram and a 120Gig SSD, it did have Mint 17.3 running on it and after running Mint 18 / 18.1 for several months on my desktop PC I decided to upgrade to 18.1 on the X230i.

                                                            \n

                                                            I completed the install and on first boot after install the boot time had risen from about 40s to over 2 minutes, I suspected a problem with the install so did it again with the same result. I couldn't find any issues reported on the net so resorted to installing Linux Lite which is based on Ubuntu 16.04 as is Mint 18. The problem persisted after this install despite getting near 40s boots on the Lenovo X61s with an SSD and the same Distro.

                                                            \n

                                                            I did another web search but could not find any other reports of this issue with the X230i so put a post on the Facebook community Distro hoppers. The response I got back from one member was to try MX16.

                                                            \n

                                                            MX Linux is a joint venture from the antiX and former MEPIS communities and is based on the latest Debian Stable "Jessie" with the XFCE desk top environment.

                                                            \n

                                                            I duly downloaded it and installed it in a Virtual PC using virtual box to see what it looked and felt like. The install is fairly user friendly although if you've never had experience of Linux and installed other Distributions a new user may be a bit unsure when asked about the MBR and where to put it, other than that a fairly straightforward install.

                                                            \n

                                                            On install there is a fairly good selection of the software you would need including a full install of LibreOffice, FireFox, Thunderbird, GIMP and synaptic package manager for adding further software from the repositories. MX have also included the ability to simply install codecs and additional drivers and a software installation system for popular Apps from the MX Welcome that comes up at boot or if disabled can be started form the menu. Also I installed it on a virtual 8Gig HDD and GParted reports use of 4.64Gig after install and updates, by default it only installs a 1G swap despite 2Gig allocated Ram in the VM.

                                                            \n

                                                            I liked the look of MX and decided to give it a go on the X230i, install went smoothly and lo and behold boot was back to around 40s on first boot after install. So I've updated the install, installed my packages I use that are not there by default such as Audacity, Scratch and a couple of other things I use. I've also put it on the X61s I use and again working faultlessly, so I'm happy again. Since I installed MX I found out from a member of my Makerspace/LUG that he had experienced the same problem with Ubuntu 16.04 based distro's and crippled SSD Boot times.

                                                            \n

                                                            I like MX so much when it come to time to reinstall my Desk Top PC, which is about the only PC I use that is not constantly changing OS, I think I will be putting MX on it. This is a big deal for me as I've been a loyal Mint user for over 5 years but MX is working so well on the Laptops at the moment it would be good to have the same OS on the Desktop PC as well.

                                                            \n

                                                            Will MX stop my Distro Hopping, NO, I like trying out new things that's why I have several Laptops kicking around so I have spare hardware to try out new Linux stuff, but it is good to have something stable around when you need it, hence sticking with Mint for so long on the Desktop.

                                                            Bash snippet - nullglob

                                                            \n

                                                            I recently did an HPR show about Bash filename expansion and described the 'shopt' command and its options. One of the options I talked about was 'nullglob' which controls what is returned from an expansion when no files match.

                                                            \n

                                                            When 'nullglob' is enabled, and a pattern does not match, nothing is returned. When it is disabled (the default) then the pattern itself is returned.

                                                            \n

                                                            Although I didn't think I'd ever need to, I recently wrote a script where I used 'nullglob', and thought I would share a snippet of the code to demonstrate what I did.

                                                            \n

                                                            The script is for managing mail messages containing tag and summary updates. I use Thunderbird for my mail and have configured it to drop these messages into a directory so I can process them. I use Thunderbird's message filters to do this. A certain amount of Spam is also received, and sometimes valid messages need a bit of work before they can be processed.

                                                            \n

                                                            The directory where the messages are saved (the spool area) is stored in the variable 'MAILDROP' earlier in the script.

                                                            \n
                                                              1 #\n  2 # Find the files and store their names in an array. Use 'nullglob' so we get\n  3 # nothing when there is nothing, then revert to the original setting\n  4 #\n  5 NG="$(shopt -p nullglob)"\n  6 shopt -s nullglob\n  7 MESSAGES=( $MAILDROP/*.eml )\n  8 eval "$NG"\n  9 \n 10 #\n 11 # Exit if there's nothing to do or report what's there\n 12 #\n 13 if [[ ${#MESSAGES[@]} -gt 0 ]]; then\n 14     echo "Files in the spool area:"\n 15     printf "%s\\n" "${MESSAGES[@]}"\n 16 else\n 17     echo "The spool area is empty"\n 18     exit\n 19 fi
                                                            \n

                                                            The variable 'NG' holds the state of 'nullglob' before the script modifies it. Remember that 'shopt -p' returns a list of commands that will revert the named options to their current state.

                                                            \n

                                                            Next (line 6) the 'nullglob' option is enabled.

                                                            \n

                                                            The array 'MESSAGES' is created on line 7 to hold the list of mail files found in the spool area. This is done with a pattern which matches files that end with the string '.eml'. If we didn't have 'nullglob' enabled then when there were no files the array would contain the pattern - which would be misleading.

                                                            \n

                                                            Having collected the file details 'nullglob' is turned off by executing the command in the variable 'NG' on line 8.

                                                            \n

                                                            You might think that the script could just turn 'nullglob' on then turn it off again when it's no longer needed. However, I prefer to use the technique I have shown here because it needs to have no knowledge of the state of the option before it's set, and restores that state afterwards.

                                                            \n

                                                            By line 13 the array 'MESSAGES' either contains a list of files or is empty. The script checks for these two cases by determining how many elements are in the array. Greater than zero means we have files to process and they are listed in lines 14 and 15. The script then goes on to do various things with the files.

                                                            \n

                                                            If there were no files then the script reports this and exits.

                                                            \n

                                                            That's it! This is not the only way to do this, but I like to write scripts that call as few sub-processes as I can, and this way appeals for that reason.

                                                            In order to meet basic accessibility standards, I need to have text alternatives to the audio of my online video lectures for my music appreciation class. I have a transcription tool called Dragon Dictate that can do most of the heavy lifting as far as getting a raw transcript of the audio, but the transcription it generates needs a lot of attention in terms of correction, capitalization, and punctuation. It also needs to have all of the text separated into logical paragraphs and it really helps to have proper section headings.

                                                            \n\n

                                                            There are 20 lectures in all, and I have finished doing 11 of them, but I still have nine to go and no time to do it. I had an idea to crowdsource this effort by giving extra-credit points to my students for doing little bits of it at a time. They get one extra-credit point for every one minute of lecture that they correct.

                                                            \n\n

                                                            I got the idea for this from the Distributed Proofreaders project, where volunteers work to help correct any mistakes that are found in the OCR scans of public-domain books before being posted on a website like Project Gutenberg. So far I've gotten about 30 minutes of lecture transcripts corrected by students who needed extra credit, and I have high hopes that we will finish the project either this summer or next fall.

                                                            \n\n

                                                            One excellent tool that I found while I was figuring out how to handle this project logistically is the Linux command line tool called mp3splt. I use this tool to cut the long lecture files up into one-minute segments like so:

                                                            \n\n
                                                            mp3splt -t 1.0.0 L13audio.mp3
                                                            \n\n

                                                            I also wrote my own script that will generate an HTML page with individual audio players for all of these one-minute audio files so that students can very easily choose an audio file to work on that is exactly one minute long. The script also pushes all of the audio files over to my server after creating ogg versions of the mp3s using mp32ogg.

                                                            \n

                                                            Jon was using ls *(*.mp3|*.ogg) to find all OGG and MP3 files in a directory which also held other files. However, when he wanted to copy this subset of files elsewhere he had problems using this expression in an scp command.

                                                            \n

                                                            Having done some investigations to help solve this I thought I'd put what I found into an HPR episode and share it, and this is the show.

LCM+L showcases vintage computers which provide interactive sessions, either through time-sharing operating systems or single-user interfaces. This gives users a chance to actually use the computers on-line or in person in the museum. An expansion adds direct touch experiences with contemporary technologies such as virtual reality, self-driving cars, the internet of things, and robotics. This puts today's computer technology in the context of how it's being used to tackle real-world issues. LCM+L also hosts a wide range of educational programs and events in their state-of-the art classroom and lab spaces.

                                                            knox gave a nice podcast on virtualenvwrapper - it was timely for me, I was just trying to use it the other day and not finding all the bits and pieces. So thank you for collecting that info in one place.

                                                            \n

                                                            knox asked why virtualenvwrapper behaves as it does ...

                                                            \n

                                                            introduction

                                                            \n

                                                            virtualenvwrapper is a combination of bash functions and programs.

                                                            \n

                                                            To understand how it works you need to know a little bit about bash and Linux.

                                                            \n

                                                            I know there have been some very good earlier and current! HPR shows on bash. But bash is a huge topic. The man page for it was 3500 lines about 10 years ago ...now it is 4300 plus lines. It has a LOT of functionality, and when you're just trying to get something done, it's overwhelming to look at. So in this HPR episode, I will just answer one or two of knox's questions. It gives me an excuse to make an episode.

                                                            \n

                                                            Also I'm not going to go too deep into the description. In order to keep the podcast short and to-the-point, I'm just going to cover what is needed. There is lots more depth - there are several shells you could use and I'm only going to talk about bash; at startup bash can read more than just the files I mention in this podcast ... I'm just not going to cover all the possibilities. That's what the over 4300 line man page is for : -). If you have questions, ask them in the comments, or make your own podcast and ask them!

                                                            environment for processes

                                                            \n

                                                            A program that has no inputs is not flexible or powerful. As a simple example, a program that displays the results of a hard-coded search is certainly useful if you want to know about that hard-coded search term. But a program that can search for a term that you specify at run time is so much more useful. You do not have to recompile the program to change the search term.

                                                            \n

                                                            Programs can receive inputs in several ways.

                                                            \n

                                                            On Linux and other unix-like OSs, a program can be run with arguments, read and write to file descriptors (and that includes standard in, standard out and standard error), they can receive signals - and they have another input: the "environment". That is a bunch of key-value pairs that are made available to the program when it starts. Some examples of environment variables are PATH, HOME, EDITOR and PAGER. The name of the environment variable, 'PAGER', is the key, and the thing on the other side of the equals sign, like 'less', is the value - the pair make up a key-value entry in the environment.

                                                            \n

                                                            People who program in C or C++ and maybe other languages know that the program starts with a main function, and that function has some parameters. The first one is a count of arguments and the second one is an array of strings, each string being one of the arguments passed to the program when it is launched. There is a little-known optional third parameter: an array of strings that represents the "environment".

                                                            \n

                                                            The way the program gets these strings is that it inherits them from its parent process. The parent process of programs that are run from the command line is ... the command line itself, bash. Or csh, or whatever your shell is. When the program starts, it gets a copy of the exported parts of the environment of its parent.

                                                            \n

                                                            environment in bash

                                                            \n

                                                            Bash gives you the ability to set these environment variables and mark them as "available for handing to subprocesses", and that is what is happening when you give that "export" command.

                                                            \n

                                                            You can view all the currently defined variables that have been marked for export by using the "env" command with no arguments. E N V - echo november victor. Or, env, short for environment.

                                                            \n

                                                            Since these variables are passed down the generations from parent to child, it is usually sufficient to define it once at the top level.

                                                            \n

                                                            The command line itself is a program called bash. It reads some files at startup.

                                                            \n

                                                            As an example of the "generations", you can call bash from within bash. And you can call bash again from within that bash. Then the first bash is the parent of the second one, and the second one is the parent of the third. The third bash is the child of the second.

                                                            \n

                                                            You can see the environment changing: Set a variable fred=one in the first shell and export it:

                                                            \n

                                                            export fred=one

                                                            \n

                                                            then run bash. In that bash you can echo $fred, and see that fred is one. Now you can change fred to two:

                                                            \n

                                                            export fred=two

                                                            \n

                                                            and run the third bash. In the third bash, you can see that fred is two:

                                                            \n

                                                            echo $fred

                                                            \n

                                                            now exit bash with the exit command.

                                                            \n

                                                            If you echo $fred, you will see fred is still two, since we set it to two just before we ran the third bash. But if you exit again, you will be back to the first bash, and you will see that fred is now one. This is the environment that bash had, just before you launched the second bash. The second and third environments are gone - those processes terminated when the exit command was given on their prompts; and when they did, their environments were cleaned up and removed.

                                                            \n

                                                            In the show notes, I have another exercise to help with understanding this environment thing.

                                                            \n

                                                            Here's another exercise to illustrate this principle. Type bash and
                                                            \nenter, and you will be in a subshell. If you show a process listing
                                                            \nin a hierarchical format, with children indented from their parents,
                                                            \nyou will see that the bash you are currently in is a child of
                                                            \nanother bash. The command to see the list of running processes in
                                                            \nhierarchical format is:

                                                            \n

                                                                ps -efH

                                                            \n

                                                            There are several bash processes. In order to pick out the bash
                                                            \ninstance that I'm running, I look for the ps process, because it has
                                                            \na uniqe string in the arguments: -efH. In the less session, search
                                                            \nfor 'efH' by typing "/efH". The screen will jump to where the
                                                            \nps -efH process is, and highlight the "efH" string that you searched
                                                            \nfor. The line you searched for will be at the top of the display
                                                            \n... to see the few lines above, type "kkkk" (one k for each line to
                                                            \nmove up). To exit from less, type q.

                                                            \n

                                                            Go ahead and export another made-up variable - perhaps your street name:

                                                            \n

                                                               export CHESTNUT=rizwan

                                                            \n

                                                            Make sure it is there with the env command:

                                                            \n

                                                               env | grep CHESTNUT

                                                            \n

                                                            and then run another subshell, and search for it again:

                                                            \n

                                                               bash
                                                            \n   env | grep CHESTNUT

                                                            \n

                                                            Exit the various shells with the "exit" command or by typing ^D. If
                                                            \nyou exit the subshell, and the shell in which you created the
                                                            \nCHESTNUT environment variable, you can run the env command and
                                                            \nsearch for that environment variable - it will not be there. The
                                                            \nprogram in which the environment variable was created has terminated,
                                                            \nand its environment has been discarded.

                                                            \n

                                                            bash startup files

                                                            \n

                                                            When bash is a login shell, it reads ~/.bash_profile. When it is not a login shell, but some subshell of the login shell, it reads ~/.bashrc.

                                                            \n

                                                            So for things that you only need to set once, you can put them in ~/.bash_profile. For things that you have to run for each new subshell, you put them in .bashrc.

                                                            \n

                                                            (Note that most distributions will set up the user accounts so they will run ~/.bashrc from .bash_profile for interactive shells)

                                                            \n

                                                            the PATH

                                                            \n

                                                            This is important, because of two things. The first is the PATH. The PATH is one of the environment variables that is used by the system to look for executables. So if you want to run a program, it should be in one of the directories on the PATH, or you will have to specify the full path to the program when running it.

                                                            \n

                                                            When you first get your account on a system, there is a default version of the .bashrc and .bash_profile files. In .bash_profile there should be a definition of the PATH. It contains the system directories like /usr/bin and /bin - you don't want to remove those from your path or your shell will become next to useless - you will have to use full paths for all commands. So the way that people add directories to the PATH is to assign the existing value of PATH to itself, plus the desired new directories. For example:

                                                            \n
                                                            \n

                                                            PATH=$PATH:/home/bjb/bin

                                                            \n
                                                            \n

                                                            But if you put this in .bashrc, then every subshell will have another copy of the directory /home/bjb/bin tacked onto the end of the PATH. So the right place to put this definition is in ~/.bash_profile, where it will be executed once and then inherited by all the subshells.

                                                            \n

                                                            shell functions and aliases

                                                            \n

                                                            However not everything you need in the shell is inherited from the parent program. It turns out that another facility that bash supplies and that virtualenv uses is the ability to define and execute bash functions. Bash also has aliases.

                                                            \n

                                                            A bash function is a series of bash commands that have been given a name, and that you can run by typing that name. It can also receive arguments that can influence how the function will behave. HPR episode 1757 by Dave Morriss called "Useful Bash Functions" talks about bash functions.

                                                            \n

                                                            You can see the list of currently defined bash functions by using the bash command: declare -F

                                                            \n

                                                            An alias is a simpler version of a function - it is (usually) just a shorter string to represent a longer or more complicated command, to make command line use easier (assuming you can remember all the aliases in the first place).

                                                            \n

                                                            You can see the list of currently defined aliases by using the bash command: alias

                                                            \n

                                                            virtualenvwrapper makes use of bash functions. This has consequences.

                                                            \n

                                                            the bash builtin command 'source'

                                                            \n

                                                            One is that you need to define those functions in every subshell. That's why you need to put "source /usr/local/bin/virtualenvwrapper.sh" in your bashrc.

                                                            \n

                                                            Well it seems that on a Debian system virtualenvwrapper puts the workon shell function into your shell via a more convoluted route. I will describe it in the show notes. But in the end, the virtualenvwrapper file that defines the virtualenvwrapper adds the function workon to your shell by sourcing the file /etc/bash_completion.d/virtualenvwrapper whenever .bashrc is sourced. (Note that "." is shorthand for the bash "source" built-in command.) The "workon" function is defined in /etc/bash_completion.d/virtualenvwrapper (the definition is about in the middle of the file.)

                                                            \n

                                                            - ~/.bashrc sources /etc/bash_completion or /usr/share/bash-completion/bash_completion
                                                            \n  (whichever one it finds first);
                                                            \n- which sources /usr/share/bash-completion/bash_completion;
                                                            \n- which sources all the files in /etc/bash_completion.d
                                                            \n- one of which is virtualenvwrapper.sh
                                                            \n- which defines the bash function workon.

                                                            \n

                                                            Look at that, on a Debian system "apt-cache show virtualenvwrapper" does indeed list bash-completion as a dependency. The virtualenvwrapper upstream does not assume you will be using command completion, and in the comments at the top of the /etc/bash_completion.d/virtualenvwrapper file tell you to put "source .../virtualenvwrapper.sh" into your ~/.bashrc file.

                                                            \n

                                                            A description of bash-completion could be a topic of another podcast (I'm not actually volunteering to do this one, heh, just suggesting it as a topic).

                                                            \n

                                                            life cycle of environment

                                                            \n

                                                            Another consequence is this: When you run a program, it will inherit a copy of the environment of its parent. When it is done, it will exit and that environment will disappear. So, you cannot run a program or subshell to try to affect your environment. It will affect the subshell or program environment, and as soon as the command is done, that updated environment will disappear.

                                                            \n

                                                            The "source" built-in bash command is meant to allow you to run a bunch of commands in a file as if they had been typed on the command line. So you can put commands that affect the environment, and the environment will still have the changes when the sourcing is done.

                                                            \n

                                                            back to virtualenvwrapper: conclusion

                                                            \n

                                                            So, virtualenvwrapper is mainly changes to the environment. It consists of a few files that are stored in ~/.virtualenvs, with names like postactivate and premkvirtualenv. They are basically hooks to add functionality before and after the commands you would issue for virtualenv, so you can customize virtualenv.

                                                            \n

                                                            To understand virtualenvwrapper, let's have a quick look at virtualenv first. The things you do with virtualenv are to create a virtualenv, destroy one, and activate one.

                                                            \n

                                                            So the things you can do with virtualenvwrapper are to run some script or scriptlet before or after you create a virtualenv, destroy a virtualenv, or activate a virtualenv.

                                                            \n

                                                            The main thing to customize is the "where to find the activate file" and the "what to do after activating 'postactivate'".

                                                            \n

                                                            It does this by setting environment variables (like PATH and PYTHONHOME) appropriately and by defining bash functions to do things like change directory to where the project is.

                                                            \n

                                                            You just have to edit .virtualenvs/postactivate to contain the location of your project files. You also define WORKON_HOME to be the directory that contains all your virtualenvs (for me that is /usr/local/pythonenv, but for most people it will be some directory in their home directory.

                                                            \n

                                                            Summary

                                                            \n

                                                            virtualenv manipulates the environment in order to allow you to have different python setups for your different projects - handy if you have one project that depends on different versions of python packages than another project and you want to run both.

                                                            \n

                                                            But virtualenv leaves a few rough edges, like leaving it up to you to find the virtualenv in order to source the activate script. That is where virtualenvwrapper comes in.

                                                            \n

                                                            We have talked about the environment, and how virtualenvwrapper manipulates the environment to make it easier to work with the virtualenvs that you have created.

                                                            \n

                                                            The environment refers to the set of environment variables that are defined and passed to child processes. We also discussed the process hierarchy and that a new environment is created for a new process, and it is destroyed when that process exits. We covered sourcing a file of shell commands, so that if those commands affect the environment, then when the sourcing is done, the environment left is the one that was changed and the changes persist past the source command. We talked about the .bash_profile and the .bashrc files.

                                                            Introduction

                                                            \n

                                                            In April 2017 my son and I decided to each build a digital clock. I had been interested in the idea since seeing Big Clive build one on YouTube, and I think my son had been similarly motivated.

                                                            \n

                                                            He found one, which I have linked to below. It's smaller than the one shown by Big Clive, comes from ShenZhen China, and costs $5.35 (about £4.18) postage free. It takes a long time to arrive, so patience is needed!

                                                            \n

                                                            There are many digital clock kits on eBay, and lots of YouTube videos showing how to build them. I think it's a great project for someone wanting some soldering practice which is a little more demanding than a beginner project.

                                                            \n

                                                            One type to avoid, I think, is the surface mount type. The one I have uses a through-hole PCB, but I have seen some that provide SMD (surface-mounted device) components. That type of soldering is beyond me at the moment (though my son has been teaching himself to do it).

                                                            In this episode, I will (very) briefly go over loops in the Awk programming language. Loops are useful when you want to run the same command(s) on a collection of data or when you just want to repeat the same commands many times.

                                                            \n

                                                            When using loops, a command or group of commands is repeated until a condition (or many) is met.

                                                            \n

                                                            While Loop

                                                            \n

                                                            Here is a silly example of a while loop:

                                                            \n
                                                            #!/bin/awk -f\nBEGIN {\n\n# Print the squares from 1 to 10 the first way\n\n    i=1;\n    while (i <= 10) {\n        print "The square of ", i, " is ", i*i;\n        i = i+1;\n    }\n\nexit;\n}
                                                            \n

                                                            Our condition is set in the braces after the while statement. We set a variable, i, before entering the loop, then increment i inside of the loop. If you forget to make a way to meet the condition, the while will go on forever.

                                                            \n

                                                            Do While Loop

                                                            \n

                                                            Here is an equally silly example of a do while loop:

                                                            \n
                                                            #!/bin/awk -f\nBEGIN {\n\n    i=2;\n    do {\n        print "The square of ", i, " is ", i*i;\n        i = i + 1\n    }\n\n    while (i != 2)\n\nexit;\n}
                                                            \n

                                                            Here, the commands in the do code block are executed at the start, then the looping begins.

                                                            \n

                                                            For Loop

                                                            \n

                                                            Another silly example of a for loop:

                                                            \n
                                                            #!/bin/awk -f\nBEGIN {\n\n    for (i=1; i <= 10; i++) {\n        print "The square of ", i, " is ", i*i;\n    }\n\nexit;\n}
                                                            \n

                                                            As you can see, we set the variable, set the condition and set the increment method all in the braces after the for statement.

                                                            \n

                                                            For Loop Over Arrays

                                                            \n

                                                            Here is a more useful example of a for loop. Here, we are adding the different values of column 2 into an array/hash-table called a. After processing the file, we print the different values.

                                                            \n

                                                            For file.txt:

                                                            \n

                                                            \n

                                                            Using the awk file of:

                                                            \n
                                                            NR != 1 {\n    a[$2]++\n}\nEND {\n    for (b in a) {\n        print b\n    }\n}
                                                            \n

                                                            We get the results of:

                                                            \n

                                                            \n

                                                            In another example, we do a similar process. This time, not only do we store all the distinct values of the second column, we perform a sum operation on column 3 for each distinct value of column 2.

                                                            \n

                                                            \n

                                                            We get the results of:

                                                            Hi Tony Hughes here with the 4th show of some short interviews I did during the Liverpool Makefest held on the 24th June 2017 at Liverpool Central Library.

                                                            Oops! Where did half of 2015, all of 2016 and the first half of 2017 go?

                                                            \n

                                                            Well, life got in the way, plus motivation dwindled somewhat. This series is very demanding - the sed series was a walk in the park compared to tackling the continental-scale landscape of Vim!

                                                            \n

                                                            Still, the original goal was to try and introduce the really useful features of Vim and to make it manageable for everyday use. The hope was, and still is, that the series could get people started on their own journeys through its marvels.

                                                            \n

                                                            Also, with the currently circulating StackOverflow article on "How to exit the Vim editor?", it's worth pointing out that we dealt with that subject in episode 1, and this issue is revealed as the ridiculous meme that it really is!

                                                            To recap, the last episode of this planned series was in March 2015. Here's a list of links to all of the episodes so far:

                                                            \n\n

                                                            Let's briefly describe what was covered in these episodes to set the context.

                                                            \n

                                                            So far we have looked at very basic editing in episode 1, where we mentioned modes Normal, Insert and Command modes.

                                                            \n

                                                            In episode 2 we looked at Vim's backup mechanism, undoing and redoing changes, and file recovery in the event of a problem. We started using the .vimrc configuration file.

                                                            \n

                                                            We began looking at movement commands in Normal mode in episode 3, and beefed up the configuration file somewhat.

                                                            \n

                                                            More movement commands were covered in episode 4 as well as searching. We began looking at commands that make changes, adding, inserting, deleting and changing text in various ways. The concept of doing these things with various movements was covered. Again, a number of useful options for the configuration file were introduced.

                                                            \n

                                                            Sorry this is such a short episode. I don't know what came over me, I was just listening to Mr.X talking about doing something with Python in Hacker Public Radio episode 2340, and for some reason I just felt a compulsion to record some kind of episode myself. It was so strange. I'm way behind on my Hacker Public Radio contribution duties anyway, so here's a quick, geeky tutorial about a thing I did with a Raspberry Pi just to try it.

                                                            \n

                                                            The temperature sensor I'm using is one of the many "1-wire" protocol devices supported by established kernel drivers, hence the reference to loading the modules for it:

                                                            \n
                                                            sudo modprobe w1-gpio\nsudo modprobe w1-therm
                                                            \n

                                                            The part about adding "dtoverlay=w1-gpio" to /boot/config.txt and then rebooting is also necessary, otherwise the modules load but no devices show up in /sys/bus/w1/devices/ .

                                                            \n

                                                            Part of the fun was coming up with a way of extracting the temperature reading in useful form without having to write a bunch of unnecessary python code. Not that there's anything wrong with python, but I get the impression that some people think everything "RaspberryPi" has to be written in python. An example of this that amused me is the piFM project, which cleverly abuses the first-generation Raspberry Pi spread-spectrum circuitry to turn it into a surprisingly powerful FM radio transmitter. This project had two ways to run it - the actual compiled C program that takes input audio and makes FM radio come out...and a python "module" that was literally just a system call that...ran the C program that takes the audio and makes FM radio come out.

                                                            \n

                                                            Examples of reading the temperature data that I ran into tended to also be short python scripts, so I took it as a challenge to do without, resulting in the fun-to-recite command in the episode, which on my system is:

                                                            \n
                                                            echo "scale=3; (`grep -o "[[:digit:]]\\{5\\}" /sys/bus/w1/devices/28-05167380f6ff/w1_slave`/(5000/9))+32" | bc
                                                            \n

                                                            As an example of what you get with a correctly connected and configured DS18B20 module on a Raspberry Pi, in my case the device shows up as:

                                                            \n
                                                            /sys/bus/w1/devices/28-05167380f6ff/
                                                            \n

                                                            Your device's number after the "28-" will be different, so just replace my example with your own device's number.

                                                            \n

                                                            If you read the "w1_slave" virtual-file in that directory, you get something that looks similar to this:

                                                            \n
                                                            67 01 4b 46 7f ff 0c 10 c4 : crc=c4 YES\n67 01 4b 46 7f ff 0c 10 c4 t=22437
                                                            \n

                                                            To be completely proper, one probably should validate that output to make sure the CRC matches so you know for sure that the read of the temperature data was correct, but I've had Zabbix checking my living-room temperature once every minute for a couple of days now and seen no odd readings or failures, so I'm not going to bother making anything more complicated than my hypnotic one-liner, unless I ever try to use the same kind of setup to monitor something more important, like a tank of expensive fish or a bioreactor full of beer.

                                                            \n

                                                            If you want some more detailed connection instructions for the DS18B20 temperature sensor and the Raspberry Pi, here is one of the many online pages with the whole process:

                                                            In this post I will show you how to take a default Raspbian Image and safely enable ssh by allowing remote access only with authorized keys.

                                                            \n

                                                            Recently, and correctly, the official Raspbian Pixel distribution disabled ssh with the note that from now on SSH will be disabled by default on our images.To understand why this is a good thing please read A security update for raspbian pixel. In short, having 11 million computers out there in the hands of non security professionals, with a known username and password, is not a good idea.

                                                            \n

                                                            That said there are many cases where you want to access your Pi remotely, and a key part of that is the ability to access it securely via ssh.

                                                            \n

                                                            The Raspberry Pi site offers a solution for how to reactivate ssh. One option is via the GUI, Preferences > Interfaces> SSH > Enabled. Another is via the console sudo raspi-config > Interfacing Options > SSH > Yes > Ok > Finish. The third offers a more interesting option.

                                                            \n

                                                            For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD card. When the Pi boots, it looks for the ssh file. If it is found, SSH is enabled, and the file is deleted. The content of the file does not matter: it could contain text, or nothing at all.

                                                            \n

                                                            This is exactly what we want. Normally you would burn the image, then boot it in a Pi with a keyboard, screen and mouse attached, and then add the file. A shortcut to that would be to burn the image, eject it, insert it again, mount the sdcard boot partition, and then create a file called ssh.

                                                            \n

                                                            I don't like either of these solutions as they involve varying amounts of user intervention. I want a solution that will automatically leave me with a modified image at the end without any intervention (aka human error) on my part.

                                                            \n

                                                            So I want to build a script that can handle the following steps:

                                                            \n
                                                              \n

                                                              • \n
                                                            • Verify it is valid
                                                              • \n
                                                            • Extract the image itself
                                                              • \n
                                                            • Enable ssh
                                                              • \n
                                                            • Change the default passwords for the root and pi user
                                                              • \n
                                                            • Secure the ssh server on the Pi
                                                              • \n
                                                            \n

                                                            I could add to this list and customize every aspect of the image, but my experience has shown that the more you modify, the more maintenance you will need to do. When changes are made to the base Raspbian image, you will need to fix your scripts, and worse is the job of updating all those already deployed Pi's.

                                                            \n

                                                            A better approach is to use the base images and control them with automation tools like Ansible, chef, puppet, cfengine, etc. This allows the images to be treated as Cattle rather than Pets, to see what that means see Architectures for open and scalable clouds, by Randy Bias, VP Technology at EMC, Director at OpenStack Foundation.

                                                            \n

                                                            Another approach to consider would be to Network Boot your Raspberry Pi and in that way the sdcard is barely used, and all traffic is run off the network. If you are deploying a lot of pi's in a area with a good physical network then this is a great option as well. This has the advantage that all the files are kept on the network and can be completely controlled from a central location.

                                                            \n

                                                            If you can't be bothered to stick around and find out how I did it, you can download the script fix-ssh-on-pi.bash from git hub. Remember that it is intended more as inspiration rather than a working tool out of the box. I deliberately wrote it so you must edit it to make it fit your needs.

                                                            \n

                                                            Starting from the comment by David Whitman to the last round table, we talk about frequency, wave length, propagation velocity and their relations. https://en.wikipedia.org/wiki/Wavelength. Approximate wave length values are commonly used to reference to entire "frequency bands", which are the frequency spectrum portions allocated to a certain radio service in proximity. Status of (amateur) frequency allocation may vary with band or country. They may not be "exclusive" and there can be "primary" and "secondary" radio services sharing that spectrum. Secondary services must not interfere with primary ones, while the other way round has to be accepted.

                                                            \n

                                                            What frequency is most powerful? - It depends! We ramble a bit how different frequencies have different propagation depending on certain factors like daytime, time of year, sun spot cycle. - Please help out with more in depth information here! Join us. There is a varying maximum and a minimum useable frequency for ionospheric propagation. https://en.wikipedia.org/wiki/Maximum_usable_frequency

                                                            VHF (globally > 30MHz) and UHF (> 300 MHz) waves have a more line of sight propagation. Steve shortly introduces the concept of repeater stations. Usually at an exposed location, a repeater retransmits the signal that is received at another frequency, thus extending communication range. Participants only need to reach the repeater in order to be able communicate with each other. We hint at additional propagation modes for VHF, like sporadic E-layer propagation, but are not able to go into detail. - Please tell us, if you have experience in those fields!

                                                            Some thoughts about RF output power and how it is less important if conditions are right.

                                                            Modulation: Putting "information" onto a radio frequency signal. Staring out as a clean "carrier wave", its parameters are modified according to the modulation scheme. We start out and explain the basic concepts of amplitude modulation, AM, where the amplitude of the radio wave is altered by the modulating signal. Then frequency modulation, FM, where the modulation process influences frequency of the output signal. We use voice audio as an example as modulation content, but this can of course be of digital nature. SSB, single side band modulation. It is the standard voice modulation mode for short wave amateur communication. We give a very brief explanation of one possible way of generating it. We discuss how it is more efficient than AM in regard to occupied frequency spectrum use and transmit power.

                                                            \n

                                                            This leads to ideas how great it would be if someone could record a show about those things, including audio examples. We further digress in how it may be a good idea to single out individual topics separate shows. The "rabbit holes" (tm MrX I think) we fall in while explaining other stuff. Make them available to be simply referenced in later shows and we can concentrate on the topic at hand.

                                                            This show is about putting the new Raspbian image onto one of the Lenovo x61s laptops that I have previously talked about.

                                                            \n

                                                            These laptops do not have a DVD drive so normally I would create a boot flash drive using USB image writer in Linux Mint, but I had received a DVD of Raspbian with the MagPi magazine so I connected a portable USB DVD drive that I have and used the disc to install to the laptop.

                                                            \n

                                                            On booting to the DVD drive you get several options including a live session with persistence (this allows the saving of data and system changes to a flash drive during the session if wanted), but the option I chose was to install to hard drive.

                                                            \n

                                                            This gives a simplified Debian installer and for new users with no previous experience of installing Linux it recommends one of the options at each stage. The only issue I had was at the stage it asks where to install Grub it does not automatically highlight the main drive (Sda) a small gripe but for a newcomer it could confuse.

                                                            \n

                                                            That said the install went flawlessly and upon first boot I was left with the PIXEL desktop with the task bar at the top of the screen and a short cut for the recycle bin. The boot time on this laptop with a Core2Duo 4Gig Ram and 120Gig SSD was about 30 seconds which is good also it was only using 87mb of the available RAM on start up, this shows the credentials of an OS built to run on the original 256mb Pi.

                                                            \n

                                                            First job is to navigate to Raspberry config from the menu bar by going to:

                                                            \n

                                                            Open Menu > Preferences > Raspberry Pi Configuration.

                                                            \n

                                                            From here you have a number of options but the important one is to change the default password from raspberry to something a little more secure.   After this I connected the Laptop to my WiFi network which is flawless on the x61s as it is an Intel WiFi card, I can't comment on other cards here.

                                                            \n

                                                            The next task that I did was to run the terminal commands 'sudo apt update' & 'sudo apt upgrade'. This will result in an updated system with all the security fixes installed and any package upgrades that are available.

                                                            \n

                                                            The one thing I was not happy about is that Raspbian allows 'sudo' access for terminal commands without requesting a password by default, this can be fixed if you feel this is a major issue depending on what you are using the device for.

                                                            \n

                                                            After completing the upgrade I decided to add the 'Synaptic' package manager to the install as this makes finding software a little easier if you not sure exactly what you're looking for. This is as simple as 'sudo apt install synaptic' in the terminal and once installed you'll find a link to it under preferences in the menu.

                                                            \n

                                                            One thing that I found that did not work out of the box was Audio, I had to install some Alsa packages and audacity to collect the needed dependencies for the audio to work. So I installed Alsa player, Alsa mixer GUI and Audacity and after this and a reboot miraculously audio now worked.

                                                            \n

                                                            Also there was not battery monitor installed so I installed Batmon so that I could check the battery status of the laptop.   On the whole given that Raspbian has been built to be compatible with all iterations of the Raspberry Pi board the software installed by default while minimal includes all the basics for web use - Chromium, email - Claws and office work - Open Office suit, along side all the Pi favourites such as Scratch (including Scratch 2) and Python programming tools.   Would I use Raspbian x86 as a daily driver, with a few tweaks, I might, particularly on an older PC/Laptop. I need to try it on an old Atom Net Book to see if it will work well on a really low specified system but a Pentium 4 with a couple of gig of RAM should work reasonably well as a development and homework PC for a school student so could extend the life of an old machine you may have kicking around. But a Core2Duo is definitely a goer, even with a basic 1Gig of Ram it should work quite well and 2Gig or better no issues at all.

I had set up a "Direct Debit" arrangement with my bank many years before which allowed them to do this, and had forgotten all about it.

                                                            \n

We used to watch all the over the air channels, and when things started to move towards digital in the UK I bought a PVR (aka DVR) which converted the Freeview channels into a signal for my analogue TV, and also recorded stuff on demand.

                                                            I throw out my TV

                                                            \n

                                                            The old analogue, CRT TV sitting in the corner of my room (and the associated Freeview PVR) had not been turned on for 4 years, so it was time for them to go. So I took my TV to the recycling centre with the help of my son. The PVR will be hacked for useful components.

                                                            \n

                                                            I cancel my licence

                                                            \n

                                                            Next step was to stop paying this annual licence. The letter told me what to do. I discovered I fulfilled all the requirements listed there:

                                                            \n
                                                              \n
                                                            • I never watch or record programmes as they are being shown on TV
                                                              • \n
                                                            • I never download or watch BBC programmes on demand
                                                              • \n
                                                            • I don't do this on a TV, desktop computer, laptop, mobile phone, tablet, games console, digital box or DVD/VHS recorder.
                                                              • \n
                                                            \n

                                                            I called the number on the back of the letter and cancelled.

                                                            \n

                                                            The guy I spoke to said I'd get a letter of confirmation soon. I asked if they'd cancel the Direct Debit or whether I should. He advised me to cancel myself, so I did it immediately.

                                                            \n

                                                            I get my confirmation letter

                                                            \n

                                                            A number of days later I received a letter entitled (rather oddly) "Your No Licence Needed confirmation". It told me my no licence was valid from July 2017 and expired July 2019.

                                                            \n

                                                            The letter did point out that I might receive a visit to "confirm that a licence isn't needed".

                                                            \n

                                                            A friendly leaflet accompanying the letter contained the question and answer:

                                                            \n

                                                            Can I be prosecuted for watching BBC programmes on BBC iPlayer without a licence?

                                                            \n
                                                            \n

                                                            Yes. From 1 September 2016, you risk prosecution and a fine of up to £1,000 plus any legal costs and/or compensation you may be ordered to pay.

                                                            \n
                                                            \n

                                                            I get an urgent letter from TV Licensing

                                                            \n

                                                            On the 12th August I received a letter from TV Licensing which asked me to call them urgently because my bank had declined a Direct Debit payment request.

                                                            \n

                                                            I called on the 14th August and was told that this was a mistake and the letter could be ignored.

                                                            \n

                                                            However, to get this answer I had to navigate 4 menus and give my details to a robot. Of course the person I eventually contacted asked for the details all over again! This made me wonder if the robot is there for any purpose other than to be a deterrent to callers. The same goes for the 4 menus.

                                                            \n

                                                            I get a phone call from TV Licensing

                                                            \n

                                                            On 17th August I found a message on my answering machine asking me to call TV Licensing. I did so, and navigated the 4 menus again. This time the robot asked for my licence number, but since I reasoned I didn't have one I gave it the reference number of my no licence. That didn't work.

                                                            \n

                                                            It then asked for my postcode, street name, house number and payment details. It confirmed the address stuff but when I said I didn't pay for a licence it passed me to a human.

                                                            \n

                                                            The lady I was speaking to then asked for my name, address, postcode, etc. I asked why I was being asked for this again having just given it to a robot. Apparently these weren't passed through because I "failed" to answer all the questions properly. That's odd because the same happened last time when I got the questions "right"!

                                                            \n

                                                            This time it turned out that the problem was that my no licence had been cancelled. No reason was given.

                                                            \n

                                                            I asked why, if a thing I had carefully set up with the expectation of it remaining in place for 2 years had been cancelled, I hadn't been notified. I didn't get an answer.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            It seems that TV Licensing has one of the worst systems for managing its "customers" on the planet. I told the representative that this was my opinion while I was on the phone.

                                                            \n

                                                            I'm wondering what's next in the saga. Will it be the "heavies" at the door (I'm not obliged to let them in without a warrant, I discovered), a legendary TV Detector van outside my house (I'd like to see one and take a picture of it), another spurious money demand or unexplained loss of my details?

                                                            \n

                                                            However, although it has been bad, this story did give me something to write and talk about for HPR so it's not all bad!

                                                            In the UK there is a lot of competition in the telecoms business but, in reality, most of the players rely on infrastructure owned and operated by one company - BT.

The emphasis of the providers is, understandably, areas of high population concentrations. The problem is that nowadays a lot of people living in rural areas need fast and reliable internet connections to do their jobs and run their businesses.

                                                            How to make Jam/Jelly

                                                            \n

                                                            Hi again HPR listeners, its the time of the year when I turn my hand to foraging and making Jelly from the local wild brambles.

                                                            \n

                                                            The season has started early here in the UK so I’ve already produced over 60 jars of bramble jelly this year with more to come. Thankfully I have people who donate old jam jars for reuse during the year which I store for this very time of the year so I have not had any problems with jars for storage.

                                                            \n

                                                            First on the issue of hygiene, before filling all the jars have previously been de-labelled and on the day of production are given another wash in hot soapy water, rinsed and placed in the oven and cooked for at least 15 minutes at 150° Centigrade (300° Fahrenheit) to sterilise them. All the lids are also boiled in water and kept hot until just before use for the same reason.

                                                            \n

                                                            The first thing I do in making jelly is wash the collected fruit (Blackberries) and put it in a pan with a little water to start cooking, then mash with a vegetable masher to start the process of breaking down the fruit. I also add 1 Lemon cut in half to each 1½ Kg of fruit both for the acidity and the pectin in the pith of the lemon (this helps setting the jelly as it cools). If there are any available I add wild plums to the mix in about a 10% ratio of plums to the Brambles as these are also rich in pectin.

                                                            \n

                                                            Once the fruit has boiled and broken down leave to cool, then remove the lemon skins ensuring you scrape the inside to get the gelatinous pulp into the pot as this contains the pectin. Now the fruit needs to be strained to remove the seeds etc. and just leave the juice for making the jelly.

                                                            \n

                                                            Once this has been done reduce the juice by about a third to concentrate it a little then measure the remaining juice to calculate how much sugar you will need for making the jelly. I use 1Kg sugar to each Liter of juice (1lb/US Pint)

                                                            \n

                                                            Put the juice in a pan large enough that it only comes half way up after the sugar is added as you need room for it to expand as it boils, bring the Juice back up to a boil and add the sugar stirring until it's all dissolved. This will have cooled it all down again so continue heating the juice and sugar mix until it starts to boil. At this stage you need to keep the juice boiling until it has come to Jam temp (105°C/220°F). If you have a Jam Thermometer you can use that to find the jam/jelly point. I don’t so I use a mixture of visual clues (boiling with lots of small bubbles on the surface) and using a cold plate kept in the freezer to test the Jelly as it cooks until its ready. You need to boil the juice for 10-15 minutes after it gets to temperature then put a drop of the juice on a cold saucer and leave for a minute, after which run your finger through the blob of juice and if it ripples up and stays there without closing the gap created you have Jelly. If not boil for a further 5 minutes and repeat until you have a setting jelly.

During this time you can drain your lids and lay them on a clean towel with the inside facing up ready to put on the jars (I’m using recycled store bought jars and lids. If using preserving jars follow the instructions with these.

Put on the lids of the jars ensuring they are on tightly. If they have the security pop up button as the jelly cools if the lid is on correctly this will be sucked down showing a good seal.

I fully expected this to produce a lot of wind noise in the recording, this unfortunately didn't happen, the boom microphone I'm using is obviously much less susceptible to this than my previous microphone. Still it's always advisable to never place your microphone directly in front of your mouth. I tend to put mine at about chin level while making sure my chin never actually touches it.

                                                            First off I have to admit to being a bit of a foodie and I love Sauerkraut but getting naturally fermented sauerkraut here in the UK in my experience impossible and if you can it tends to be expensive. So I went and had a look on YouTube for some instructions on how to do it, and my first efforts worked well. I’ve just made another batch and took pictures as I was doing it. So this is a how to show on making Sauerkraut.

                                                            \n

                                                            Just to say that this is about making basic sauerkraut but you can add additional flavours with garlic, other veg and spices. At some point I will try chilli but this week I want the clean taste of a basic sauerkraut.

                                                            \n

                                                            I use a large white cabbage which you need to strip any outer leaves that are blemished or dirty then quarter and cut out the hard core. Now before shredding weigh the cabbage as you need this to work out how much salt you will add for each Kilo of cabbage and other vegetables, if using. You need 20 grammes of salt, nothing fancy but use one without any any additives, just pure salt, I used a rock salt which cost £1.35 for 350g. You're basically after 2% salt to weight of Cabbage and anything else you are fermenting.

                                                            \n

                                                            It’s also an idea to have about 100mls of a 2% brine to top up if needed to cover the veg in the jar if there is not quite enough liquid made during mashing.

                                                            \n

                                                            \n

                                                            Shred the cabbage and put into a large bowl with the salt, now the fun bit starts. You need to get your hands in and start to crush the salt covered shredded cabbage to start drawing out the moisture, this will take several minutes or longer depending on quantity, but you will feel the texture changing and the liquid starting to be drawn out quite soon after starting. Continue this process until the cabbage seems to have shrunk by about half and there is also a juice in the bottom of the bowl. You can cheat and do this for a few minutes then cover with food wrap and leave for up to an hour and the salt will have done some of the work for you, but you need to give it a good 5 minutes to start before you do this, and you may have to do a little more mashing before transferring to a jar.

                                                            At this stage find a jar or jars, large enough to hold all the cabbage with a little to spare, you can sterilise if you wish but a good clean in hot soapy water then rinsed and allowed to dry is sufficient as the salt kills and bad bacteria and encourages to good bacteria to grow. Put all your salted and mashed cabbage mix in the jar/jars well packed down with the juice ensuring that the juice is covering the cabbage by about 1cm (this is where the extra saline solution comes in if you don’t quite have enough.

                                                            Tuck the jar away in a storage place that’s about room temp and leave for several days checking every so often to see how it is. If the brine has evaporated you may need to top up slightly. After about a week you should have sauerkraut, give it a try, if its sour enough this is when you take it and put in the fridge or cold cellar/garage to stop the fermenting. All you have to do now is start eating, oh, and make your next batch ready for when that’s gone.

                                                            Well I’m back again, as I said in the show I did about Raspbian x86 on the Lenovo x61s, I was interested to see how the OS would perform on what I now class as very old hardware in the form of a Pentium 4 tower.

                                                            \n

                                                            We have a spare tower at the Makerspace which gets used to test low resource operating systems to see if they live up to their name, so on Saturday (yesterday as I write this, but a few weeks ago by the time this show goes out) I put the x86 Raspbian image on to this tower to see how it would perform.

                                                            \n

                                                            Tower specifications are: Pentium 4 2.8Gig CPU, 2Gig DDR Ram and a 40Gig HDD, which in its day was a very useful bit of kit, but technology has moved on and most people wouldn’t consider it any use as a working PC today.

                                                            \n

                                                            First problem I encountered was the DVD drive was duff and I didn’t have the image on a flash drive. Luckily I did have my trusty USB DVD in the bag, so I hooked that up, booted into the boot menu and set the disc off loading the OS. I won't go into this again as I ran through the install process last time, HPR 2362, but the install went well and I was left with a new install of Pixel on the tower.

                                                            \n

                                                            I went through the new install process and was left with an up to date and password secure PC, I then rebooted to check what the resource use was at first boot, which I was amazed was a consistent 66mb of RAM, and about 1% CPU use.

                                                            \n

                                                            \n

                                                            I next opened a Word document in LibreOffice, this took about 10seconds to load but once open was perfectly usable with no lag, so should provide a good office capable PC.

                                                            So you can use the Web, Write documents, it has an email client or you can use web mail. And it’s not painfully slow, this PC would now make a very usable homework/first computer for any child, or a computer for an older member of the family that just needs to keep in touch with family and friends without breaking the bank. In fact you could probably pick up a working tower off the likes of Freecycle/Freegle for £0 and you may even get a small 17”/19” TFT monitor from the same place.

                                                            \n

                                                            Yes it’s not as energy efficient as the latest kit but as I said last time the cost of a new PC/laptop can buy a lot of additional electricity in the time you may run it before it finally expires.

                                                            \n

                                                            I met Michael at Kansas Linux Fest 2017 where he was a speaker. Turns out we've probably been walking past each other in the halls at Penguicon the last three years that I have attended. Michael is a BSD guy and one of us. As well as being an open source advocate, he works professionally as a systems admin and network engineer. I bought his texts "SSH Mastery" (because I've always needed help getting my head around reverse IP tunneling), "Networking for Systems Administrators", and "$ git commit murder", his latest novel. Because I was a good customer, Michael threw in "Forever Falls" for free.

                                                            \n

                                                            "git commit murder" takes place at a BSD convention. The gathering in the novel is slightly less informal than the Linux conferences I've attended. The conference is targeted at the users, contributors, and managers of the fictional "SkyBSD". Our protagonist, Detroit native Dale Whitehead has come to Canada to deliver a talk on his mesh networking project. The conference is disrupted when attendees start to die in what appear to be unrelated accidents. Dale is unwilling to accept these deaths as accidents, and puts his analytical mind to discovering the killer. He also employees his hacking skills, having already created an admin account on the host university's server within minutes of checking in. This makes him understandably reluctant to discuss his theories with the authorities until he has positively identified a culprit.

                                                            \n

                                                            The SkyBSD community is not without contention. A significant number of contributors want to move from Subversion to git for version control and just as many are vehemently opposed. Also, the recent release of candid photos meant to embarrass a contributor has many calling for a Code of Conduct and the banning of violators. Others think this is going too far. Dale has to contemplate whether either of these is reason for murder? Perhaps it is a struggle by an old guard who is not ready to surrender leadership to a younger generation?

                                                            \n

                                                            At first, it was hard to get to like Michael's protagonist, Dale Whitehead. Dale suffers from an extreme form of Attention Deficit Disorder which requires medication and causes him to actively shun the company of other people. The same affliction that allows him to get "in the zone" when programming also makes being in crowds a fresh hell for Dale. He is in constant terror that some aberrant behavior on his part will reveal his condition to his companions and he finds it much easier to deal with other humans via e-mail or IRC. It's clear Michael Lucas has an understanding of the condition, either via research or contact with someone who suffers ADD.

                                                            \n

                                                            At least one character in the story seemed to me to bear a passing resemblance to a familiar conference fixture in real life. Michael told me the sequel might be set at an open source/Sci Fi convention in a city near the great lakes. Time will tell if the Tuesday Afternoon Solaris Overview or a kilt wearing organizer will make an appearance.

                                                            \n

                                                            "Forever Falls" is also a mystery, as well a SciFi story. Ella Forecourt is a recruit right out of college for the Montague Corporation. As a corporate security officer, she is assigned to investigate the death of a Montague research scientist at the Freefall installation. In the course of the novel, you learn that Montague has proprietary technology that allows them to "portal" into other universes or dimensions where the laws of physics are different from those of our universe. In Freefall, gravity runs parallel to the surface of the world. In other words, you don't fall down, you fall sideways, and with no ground to stop you, if you fall, you fall forever.

                                                            \n

                                                            Montague has a research facility built into the "Cliff". With gravity travelling sideways, the surface of the planet appears as an endless cliff. "Above" the facility is a huge metal awning to deflect falling boulders. On top of the awning is where the security team discovers the body of Dr. Devin Grupper. The damage to the body suggests Dr. Grupper impacted with terminal velocity. Even in the lighter gravity of Freefall constant acceleration means terminal velocity is governed by air resistance. Montague does use airships for transport, but there are no records of how Grupper could have secured transportation and a pilot to wind up smashed on the awning without a ship going missing. Thus Security Second Ella Forecourt is assigned to the case. "Forever Falls" is but one in a series of Montague Portal novels by Michael Lucas. I look forward to reading the rest of the series.

                                                            3. Base - gear used in a fixed station environment.

In Andrew's experience of 14.1 and before, only one package needed Pulseaudio, namely the game VVVVVV and even then it just wanted to see it installed, didn't need it for sound to work!

Worst case is Pandoc with its Haskell deps but sbopkg queue files are a great help there. Beni recommends sbotools as an alternative that deals with this and feels like portsnap on FreeBSD.

                                                            Tcl is an interesting language that does many things \"wrong\", especially if you're coming from a LISP perspective, and especially-especially if you're coming from a Scheme perspective. Examples are all over the C2 wiki, but probably DynamicStringsVsFunctional is the epicenter.

                                                            TL;DL: Tcl was successful because it found its niche as a lightweight yet capable language able to both integrate and be integrated with C code, but it fell behind on Tk look-and-feel compared to GNOME and KDE and also on other mainstream development phenomena, it ossified because it was afraid to upset its installed base, it got stuck between not-slim-enough and not-featureful-enough, the syntax is too weird, and it spiraled into losing touch with the rest of the free software world, which ultimately also affected business use.

The websites tend to be for fanatic bodybuilders or for pitching products. This one, though, has a pretty good catalog of exercises: https://www.weight-training-exercises.com/. Note that the same exercise may be known by several names, depending on the speaker.

Earth has been seized, and is isolated from the rest of the galaxy. Luckily, you happen to have yourself a ship built with ancient mystic technology and whatnot.

                                                            \n

                                                            I'm interested in Astronomy and listen to a number of Astronomy podcasts. I have listed a few of these in the past when doing HPR shows about the podcast feeds I subscribe to (shows 1516, 1518 and 2339).

                                                            \n

                                                            One of the recent additions to my podcast list that I have been listening to this year is called "The Urban Astronomer", which has a website here and a podcast feed here. The site and podcast are run by Allen Versfeld, who is based in South Africa.

                                                            \n

                                                            To quote from the website:

                                                            \n
                                                            \n

                                                            Allen is an amateur astronomer, an IT professional, a podcaster, a father of five beautiful kids and a barely competent chess player. He is also the director of the Astrophotography Section of the Astronomical Society of South Africa, where he coordinates and promotes the activities of people who are far better photographers than him.

                                                            \n
                                                            \n

                                                            I have been enjoying Allen's episodes a lot. There are some great interviews with some very interesting people in the world of Astronomy. Allen has a relaxed interviewing style which I find appealing.

                                                            \n

                                                            I wrote to him, commenting on one of his episodes, and I mentioned Hacker Public Radio in my email. He has subscribed to HPR and has been kind enough to mention it on a recent podcast. I'm offering you a chance to listen to one of his episodes here.

                                                            \n

                                                            The episode is number 12 of "The Urban Astronomer", from June 16, 2017. It is an interview with Jen Millard, a first year Astronomy PhD student at Cardiff University in the UK. Jen is also a host on the "Awesome Astronomy" podcast, as mentioned in the episode.

                                                            \n

                                                            I hope you enjoy listening to this example episode.

                                                            \n

                                                            The phone came with Android 7.1 and as soon as it was connected to the Internet it updated to 7.1.1 so has the latest September security patches.

                                                            \n

                                                            The first issue encountered was that this phone uses a nano SIM card for the phone network and my old One Plus used the bigger micro SIM, so I had to get a new Sim card sent to me which took 24 hours. In the mean time I was installing some of the applications that I have on the phone and checking that all my contacts had transferred to the new phone, which despite a backup of same some had not migrated, but that’s a Google issue not the phone.

                                                            \n

                                                            When the SIM arrived I put it and a 16Gig micro SD card into the SIM slot, the cards were recognized and after configuring the SD card as additional storage I was able to set my pod catcher and camera to save files to the SD card rather than internal storage thus leaving internal storage for apps and Android updates.

                                                            \n

                                                            First thing I noticed over my previous One Plus1 is how snappy everything is the CPU upgrade was definitely and improvement over my old phone. Another thing is the fact that Nokia has decided to keep the 3.5mm headphone Jack which for me is essential as I listen to music and audio recordings at some time on the phone most days. A lot has also been said about the 3000mAh battery not being up to all day use and the slowness of recharging it if needed. For my use profile I find the battery more than adequate, I surf, use social media, take occasional snaps, watch the odd You Tube video and listen to pod-casts/music, Oh and make the odd phone call.

                                                            \n

                                                            After a 14 hour day I have still got 50-60% of battery left. Granted the other night I got down to 40% it did take all night to recharge to 98% with a 2.5A charger, with the official 2A charger it does seem to be a little faster, but yes if you're a heavy user you will need to carry your charger or a portable battery for emergency top ups.

                                                            \n

                                                            So would I recommend the Nokia6 to someone in the market for a phablet, the short answer is yes, if you need the larger screen but can't afford the high end larger screen phones this is a very good mid range option, if you need to use the dual SIM capability it might be worth spending the extra £40 and getting the 64Gig version to give extra room for updates and plenty of space for Applications as you will not be able to use the expansion capacity as the second SIM uses the space where the Micro SD card goes.

                                                            \n

                                                            After the first 2 weeks or so my first impressions are this is a good phone and well worth the £200 price point.

                                                            \n

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz (Tracks > Resample > 44100). Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n

                                                            • Noise Floor: -50db

                                                            • Decay Time: 1.0 sec
                                                              • \n
                                                            • \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.
                                                              • \n
                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying or distorting any actual content. It makes a conversation sound as fluid during playback as it was when it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to pass the file through Truncate Silence ONCE, and ONLY ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound very choppy, and un-natural.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            The audio was recorded on an 'Olympus VN-1000PC' pocket dictation recorder (purchased at Walmart about 10 or 12 years ago, I think, for about $20.00-US), on the built in mic. The recorder will accept a mic and/or headphone with a 3.5mm jack size. Mini usb out as a mass storage device so its easy to offload your files. The device is simple enough for a monkey to use, or a trucker...

                                                            \nShakubuku \"break and subdue\" (折伏) is a term that originates in the Chinese Śrīmālādevī Siṃhanāda Sūtra. Although often associated with the teachings of Nichiren, the term appears often in the SAT Daizokyo and the works of the Chinese Tiantai patriarachs Zhiyi and Zhanran. The term has historically been used to indicate the rebuttal of false teachings, and thereby break negative patterns in one's thoughts, words and deeds.

                                                            Personally, I heard the term defined first on the movie, \"Gross Pointe Blank\" with Minni Driver, John Cusack, Alan Arkin and Dan Akroyd. Minnie Driver's character described SHAKUBUKU thusly,\"It's a swift, spiritual kick to the head that alters your reality forever.\"

                                                            \n

                                                            Both of these definitions work for me, the first being the more definitive, and the second being the somewhat simplistic, hipster/millennial definition, although the line was actually recorded around 1997 when the movie came out.

Then I think I heard Ken Fallon wondering about bullet journals on community news for the month with that episode. So I thought a show was in order explaining how I went from using a bullet journal to using emacs org mode.

The video tutorial https://bulletjournal.com/ is excellent. You can use any notebook and divide it up into index pages, future log, monthly log and daily log there's a visual indexing/ tagging system to help organize stuff. Its extremely customizable.

                                                            Need to be disciplined. Can be tedious to enter items in month, daily and index sections. It takes time to set up. I think Shane's use case he mentioned in podcast as sort of a project/idea book sounds pretty cool and might be a really good use case for this system. Hard to edit, this may be a strength for some people, but for me as a daily planner it was a little daunting to use. Adding stuff to something requires either leaving space ahead of time or indexing to a new page. The monthly log was always a mystery to me on how to use it. If you lose it you've lost it, no easy way to back it up

                                                            \n

                                                            At its heart an org-mode is an outliner. I use org-mode to set up daily todo tasks, organize projects, jot down notes. Org-mode has a subsystem call agenda view that can generate daily planner views from your org-mode files. I initially tried to mimic the bullet journal in org-mode, but found that it was better to approach org mode relying on its strengths, which are different, as you can imagine, from a Bullet journal.

                                                            \n

                                                            3.5 Strengths

                                                            \n

                                                            I like it because its editable, searchable and customizable. Projects can be broken down into as fine a detail as you want and that detail level can expand or contract as necessary. The power of org-mode comes out when you use it to capturing ideas, tasks and information. Capturing these events is done via capture templates that you can create. This new data is then saved to the appropriate org file then shows up in your agenda view. Its extremely easy to back up, it's text based and therefore future proof. There are many good tutorials and resources online

                                                            \n

                                                            Need to know a little about emacs and that can feel overwhelming to try. This new tool will require you to use your brain. Emacs keybindings

                                                            Trying to find a good way to use orgmode portably. mobile-org app for android doesn't work for me. This has led to trying a couple of different solutions which I will record other hpr episodes about. Thanks for listening. If you have ideas on Bullet Journals or Org-mode I'd love to hear an episode about it. I'll put links into the show notes, this is Brian in Ohio signing off.

                                                            HPR show notes which contain images or which link to other files are something we encourage. However, when uploading these to the Internet Archive (IA) at archive.org there are a number of issues:

                                                            \n
                                                              \n

                                                            • If a file has been submitted as part of the original HPR upload we copy it to archive.org and use the URL of the copy in the notes. This mechanism has been added in the past few months and seems to be working fine.

                                                              • \n

                                                            • If the notes for a show contain links to external files these do not always seem to be accessible through the archive.org interface. For example, the recent show 2406 links to an image showing the cabling of a CAT6 plug, but the archive.org copy did not show this image (though it does now - see below).

                                                              • \n

                                                            • One way of dealing with the issue of external files would be to make a copy and place it on the HPR site, then it would be uploaded to the IA as described earlier. This might have copyright issues though.

                                                              • \n

                                                            • Another way would be to point to a copy on the Wayback Machine (WM). Sometimes the file has been copied there already, or it is possible to request that the WM snapshot it. This is what was done for the IA copy of show 2406. However, it was a manual process and therefore rather labour-intensive, which is not ideal.

We comedically discuss the disillusionment that one can incur working in the cubical jungle. We also discuss going back to minimum wage after enjoying a high paying tech industry.

                                                            Beeza uses an Acer Aspire One netbook as a media player (principally audio).

                                                            The audio quality sent from the sound card out through the headphone socket really is excellent, so that when fed into a hi-fi amplifier the final reproduction is every bit as good as audio from a CD player - possibly better.

                                                            \n

                                                            The netbook is over 5 years old. When it was first bought most Linux distros ran very well on it. Since that time, however, the optimal hardware spec for most distros has increased quite considerably, leaving a humble netbook relatively underpowered, having typically 1 Gb RAM and a sedate CPU.

                                                            \n

Raspbian X86, which is very closely related to the ARM version of Raspbian as used on the Pi, has a very light footprint and delivers performance on a netbook very much like what you would have experienced when they were brand new.

                                                            \n

                                                            Raspbian X86 is not perfect, though. It works brilliantly straight out of the box, but its security model needs a bit of simple reconfiguration to get the best from it. There are also, tweaks and cheats that can improve the Pixel user interface which, in its default setup, may not be to everybody's liking.

                                                            \n
                                                              \n
                                                            1. Scan all the images using the entire length of your scanner. I use scantoimage.bash
                                                              2. \n
                                                            2. Confirm that there are no missing pages, and that every other page is upright and then upside down etc. If they are scan them and rename them so the name fits in between the pages
                                                              3. \n
                                                            3. Back up all the scanned images
                                                              4. \n
                                                            4. Manually crop the areas of the scans outside the area of the page. Usually this is on the side and bottom of the flat bed. Save is as something like ~/x.jpg
                                                              5. \n
                                                            5. Use GraphicsMagick Image Processing System to identify the dimensions of the cropped image.

                                                            6. Crop all the images to that dimension

                                                            7. Rotate every second image by 180 degrees. rotate-every-second-image.bash
                                                              8. \n
                                                            8. Create a directory for the book and in there create a subdirectory for each section of the book. Manually copy all the images to the sub directory for that section.
                                                              9. \n
                                                            9. Then go to the root where there are no files only subdirs and run the command
                                                              \nfor i in *;do echo $i;gm convert \"${i}/*.jpg\" \"${i}.pdf\"; done

                                                            I’ve now been using the Nokia 6 for about 2 months and just wanted to update listeners to my thoughts on the phone.

                                                            \n

                                                            First a response to Dave who said on the Community News that as he had a OnePlus 1 he was surprised I found it inadequate. The One+1 is a great phone, my problem with it was it does not support O2’s 4G network although it supports EE’s and 3’s 4G networks here in the UK, as I use GiffGaff which runs on the O2 network I have not been able to benefit from their 4G offer and I don’t want to change provider. Also the One+1 was stuck on CyanogenMod 13.1 (Android 6) and no longer got updates, so this was the reason for the new phone purchase. I’ve now flashed Lineage OS onto the One+1 and have a secure backup phone or one I can pass on to my Wife at some stage.

                                                            \n

                                                            Back to the Nokia, now I’ve lived with the phone for a few weeks I can say I am more than happy with it, and some of the issues with battery life I have found are unfounded once you configure some of the settings to be more battery friendly, such as restricting background access to the net for most aps the battery life is well over a day's use. At night in stand by mode over 8 hours battery use is less than 1% so even with moderate to heavy use I can get a day out of the phone without any risk of running out. Also if the official charger and cable are used a 1 hour charge gives about a 30-40% battery capacity, so not as slow as the reviews I’ve read. Would I still buy it having used it for 2 months, I would say yes to that, and I also have no issues with recommending it as a large format phone at a budget price.

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with its default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            • The while loop: tests a condition and performs commands while the test returns true

                                                            • The do while loop: performs commands after the do, then tests afterwards, repeating the commands while the test is true.

                                                            \n

                                                            Pdmenu is a tool written by Joey Hess which allows the creation of a simple menu in a terminal (console) window. It is in his list of less active projects, and the latest version is dated 2014, but it seems to be quite complete and useful as it is.

                                                            \n

                                                            I like simple menus. As a Sysadmin in my last job I used one on OpenVMS which helped me run the various periodic tasks I needed to run - especially the less frequent ones - without having to remember all of the details.

                                                            \n

                                                            I do the same on my various Linux systems, and find that pdmenu is ideal for the task.

                                                            \n

                                                            Installation

                                                            \n

                                                            I found pdmenu in the Debian repositories (I run Debian Testing), and it was very easily installed. The C source is available as a tarfile, though I\n haven't tried building it myself.

                                                            \n

                                                            Running pdmenu

                                                            \n

                                                            Simply typing pdmenu at a command prompt will invoke the utility. It uses the file /etc/pdmenurc as its default configuration file, and this generates a menu with a demonstration of some of its features.

                                                            \n

                                                            This is not particularly useful but it can be overridden by creating your own configuration, which by default is in ~/.pdmenurc. The pdmenu command itself takes a configuration file as an argument, so there is plenty of flexibility.

Additional config options based on your specific use-case are left for you to explore on your own.\n

                                                            \n

                                                            I wanted to tell a little about my trials and tribulations of finding a solution to taking org mode on the road. What's org mode? Listen to my last episode or do a duckduckgo to find out.

                                                            After switching from using a bullet journal to using emacs-org-mode as my organizing device I immediately saw that lugging a laptop everywhere was not going to work for me. I wanted to be able to access org-mode, especially the agenda view, anywhere I might be. Laptops with limited battery life and a large physical presence were not going to work for me.

                                                            \n

                                                            \n

                                                            The first solution I tried, and the most obvious, was the mobile-org app. Its available for android or ios. I can only attest to the android version. Its an easy from the play store. This solution didn't work for me for a number of reasons. First, the documentation for the setup is terrible, and I became frustrated by the workflow and could not get useful results using the app. Mobile-org seems to be built around using dropox. In order to get around that I tried various methods of syncing my org files using onboard storage. Seeing this wasn't going to work I bit the bullet setup a dropbox account installed the clients, one on my slackware laptop and the other on my phone only to find dropbox doesn't support this application anymore. A little digging around and it seems the API used by mobile-org isn't up to snuff any more so, fail. I cut my loses and moved on to another possible solution.

                                                            \n

                                                            My next crack at solving the portable org mode problem was getting a pitop laptop https://pi-top.com/. Pitop is a laptop based on a raspberrypi. I won't go into the details of the device here but I'll say my idea for using this device was its advertised 8+ hour battery life. My old linux laptops rarely give me 2 hours of life So even though the pitop was physically larger than I wanted I gave it a whirl. Lets just say the battery does last 8+ hours, it just can't survive many recharges. 2 battery packs later I gave up on the pitop and went looking for something else.

                                                            \n

                                                            I heard klaatu mention a device called a pocketchip on his gnuworld order podcast https://gnuworldorder.info/. I looked into it and here I thought might be a device that could work. Pocketchip https://getchip.com/pages/pocketchip is a handheld linux computer. After ordering the device I began setting it up for my use case. There are plenty of tutorials on the pocketchip website on how to extend the usefulness of this product. The size of the device was good and the battery life was ok. Some people complain about the chicklet keyboard but I actually did not mind it to much. It took some fiddling to get the emacs keybindings I use to work on the odd keyboard layout, but its a linux computer so there's plenty of information out there. I used a thumb drive as a repository for my org files, wrote a couple of scripts to sync up the files with whatever device the drive was plugged into and wala a mobile org solution! Alas, the pocketchips demise was its build quality. The heart of the pocketchip, the system board's usb mini plug fell off, and then one system tweak later I bricked the device. I'll recover it eventually, you can program it through the gpio pins, but this was a quest for portable-org-mode, not fixing pocketchips, so onward.

                                                            \n

                                                            I saw a build of a raspberry pi tablet that looked very nice https://www.stefanv.com/electronics/a-compact-home-made-raspberry-pi-tablet.html. Always up for a challenge, I cobbled together a prototype and tried it out. The reason I eventually dropped this solution because the virtual keyboard didn't work well and I couldn't get the official raspberrypi lcd to rotate from portrait to landscape dynamically. Still a fun project and I'll get some use out of it sometime.

                                                            Well here's the solution I came up with. I was searching around on the internet and found a link telling about running emacs on an android phone. https://endlessparentheses.com/running-emacs-on-android.html. It involves installing the termux app, the hackers keyboard, both available in the google play store and apt-get installing emacs on the phone. After that I had full emacs running, all be it in a terminal so its slightly different then running on the desktop, and with emacs you get, drum roll please, org-mode. With this i have the device I always take with running org-mode. I sink my org files between my laptop and phone using the afore mentioned drop box account. The hackers keyboard works flawlessly and can digest any emacs keybinding I need. I also have a logitech bluetoothkeyboard that I can use if I have a lot of typing to do in org-mode on my phone, such as these shownotes!

                                                            \n

                                                            conclusions

                                                            \n

                                                            I find org-mode so useful that I want it available any where I go. And over the course of the last 8 months I went on a journey trying to find a solution to that desire. In the end, the solution was pretty obvious, these portable computers we carry around are amazing and thanks to the developers of termux and the hackers keyboard my phone is now infinitely more useful to me. Thanks for listening.

                                                            OUR AUDIO

                                                            \n

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n

                                                            • Noise Floor: -50db
                                                              • \n
                                                            • Ratio: 3:1

                                                            • Attack Time: 0.2sec
                                                              • \n
                                                            • Decay Time: 1.0 sec
                                                              • \n
                                                            • \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.
                                                              • \n
                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            So what is the purpose - I had an old windows backup workstation at work that I did a lot backups with. It got to the point where it was just too slow and low spec to handle the windows 7 updates and with my company switching to the 365/sharepoint/one drive it was not needed anymore. So I wanted not to throw it away as I had sprung for 160GB hard drive a long time ago. “I know at work and purchasing a hard drive for work.” But it lasted more than 10 years doing my outlook backups and file shares.

                                                            \n

                                                            So my first problem was I was pretty sure I only had 32 bit.

                                                            \n

                                                            So no centos or suse in 32 bit. I could have went fedora but I wanted a really long time with support. So it came down to ubuntu 16.04, Debian or Net BSD with I386 repos I could use long term. I was more comfortable with Ubuntu and 16.04 has about 3 years support left on it.

                                                            \n

                                                            So what is it. I did a uname -a and and looked at the proc cpu to see what the cpu was.

In the end I said what do really know how do well with it right now. So I installed Open SSH server, tightVNC, A really thin xfce 4, ffmpeg and youtube-dl and uget. So I will play with snaps only in the future and keep this basic config.

                                                            \n

                                                            \n

                                                            Note I did not auto start VNC because I found in my creations of this server that it used too much RAM vs just starting it and killing it.

                                                            It is the perfect video processing machine in the moment. If youtube-dl can’t get it I can use uget via vnc and that will then transcode if needed. Mostly for mp3.
                                                            \nhttps://rg3.github.io/youtube-dl/ youtube-dl is a command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform specific. It should work on your Unix box, on Windows or on Mac OS X. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

                                                            \n

                                                            I will work on the nextcloud snap and other snaps as they are easy to install or remove without hurting the base system.

                                                            My daughter flew out to New Zealand before Christmas 2017 to spend some time with her brother, who had been there with his girlfriend since November. I saw her flight itinerary from the airline, but had no idea of how the times related to time back home, so I wrote a little Bash script to calculate times in UTC (my local timezone).

I like to keep track of where they are and how they are progressing through their journeys because otherwise I tend to worry. This one was a reasonably simple journey, two flights via Doha in Qatar, with not too long a wait between them. The overall journey was long of course.

                                                            The printf function allows for greater control over the output, in comparison to print.

                                                            To follow along, you can either use these show notes or refer to the gawk manual.

                                                            \n

                                                            There are 3 main areas to cover:

                                                            \n
                                                              \n
                                                            • Basic printf syntax
                                                              • \n
                                                            • Format Control letters
                                                              • \n
                                                            • Format modifiers
                                                              • \n
                                                            \n

                                                            Syntax

                                                            \n
                                                            printf format, item1, item2, …
                                                            \n

                                                            The big difference in the syntax of printf statements is the format argument. It allows you to use complex formatting and layouts for outputs. Unlike print, printf does not automatically start a new line after the function. This can be useful when you want to print all of the items in a column on a single line.

                                                            \n

                                                            For example, remember the example file, file1.csv:

                                                            \n
                                                            name,color,amount\napple,red,4\nbanana,yellow,6\nstrawberry,red,3\ngrape,purple,10\napple,green,8\nplum,purple,2\nkiwi,brown,4\npotato,brown,9\npineapple,yellow,5
                                                            \n

                                                            Look at the difference between the following outputs:

                                                            \n
                                                            awk -F, 'NR!=1{print "Color", $2, "has", $3}' file1.csv
                                                            \n

                                                            and

                                                            \n
                                                            awk -F, 'NR!=1{printf "Color %s has %s. ", $2, $3}' file1.csv
                                                            \n

                                                            Control Letters

                                                            \n

                                                            Control letters control or cast the output to specific types. Use it as a way to convert ints to floats, ints to chars, etc.

                                                            \n

                                                            %c = to char. printf "%c", 65 prints a
                                                            \n%i, %d = to int. printf "%i", 3.4 prints 3
                                                            \n%f = to float. printf "%c", 65 prints 65.000000
                                                            \n%e, %E = to scientific notation. printf "%e", 65 prints 6.500000e+01. If you use %E will use a capital E instead of e.
                                                            \n%g = to either scientific notation or int. printf "%.2g", 65 prints 65, while printf "%.1g", 65 prints 6e+01
                                                            \n%s = to string. printf "%s", 65 prints 65
                                                            \n%u = to unsigned int. printf "%u", -6 prints 18446744073709551610

                                                            \n

                                                            There are others. See documentation.

                                                            \n

                                                            N$ = positional specifier. printf "%2$s %1$s", "second", "first"
                                                            \nn = spaces to the left of the string.
                                                            \n-n = spaces to the right of string.
                                                            \nspace = prefix positive numbers with a space, negative numbers with a -
                                                            \n+ = prefix all numbers with a sign (either + or -)
                                                            \n0n = leading 0's before input. printf "%03i", 65 prints 065.
                                                            \n' = comma place holder for thousands. printf "%'i", 6500 prints 6,500

                                                            Below is an (crude) illustration of how I like to think when formatting output:

                                                                      7          2\n├──────┼───────┼────┼──┤\n Color: RedXXXX Sum: X6

                                                                   18            3\n├──────────────────╂───┤\n Total Sum:XXXXXXXX X34
                                                            \n

                                                            See the following awk file

                                                            \n
                                                            BEGIN {\n    FS=",";\n}\nNR != 1 {\n    a[$2]+=$3;\n    c+=$3;\n    d+=1;\n}\nEND {\n    for (b in a) {\n        printf "Color: %-7s Sum: %2i\\n", b, a[b];\n    }\n    print "----------------------"\n    printf "%-18s %3i\\n", "Total Sum:", c;\n    printf "%-18s %3i\\n", "Total Count:", d;\n    printf "%-18s %3.1f\\n", "Mean:", c / d;\n}
                                                            \n

                                                            This gives the following output:

                                                            I have more time to listen to books than to read them. I have no issues listening to audio books on my commute or when taking walks. The problem occurs at work. I have about 4 hours a day I could be listening to audio books. Over the years I've tried countless times, all with the same result. I get distracted by work and find I've missed key parts of the story and end up listening to music or podcasts I don't mind missing instead.

                                                            \n

                                                            There's nothing wrong with music or podcasts I don't mind missing but that doesn't help with my growing list of books I want to 'read'.

                                                            Be able to listen to an audio book and have reasonable comprehension. Super Simple. I can't be seen as messing around with my player more than whatever it is that's keeping me from my player :)

                                                            \n

                                                            Normally I listen to books in one large file because at one point in time it was easier for me to keep track of them in my player and bookmarking was easier for my little brain to handle. But I got to thinking this might solve the problem of wasted time when needing to repeat sections of the book. If the book were broken into pieces, I wouldn't need to repeat as often. I tried listening to 3 chapters at a time and had two issues. The first is that 3 chapters is still quite a bit of time and I was repeating sections I didn't need to repeat. For example, I might have been able to follow along with chapter 1 but not chapters 2 and 3. This meant repeating chapter 1 or messing around to manually skip chapter 1 when I repeat. Not good.

                                                            \n

                                                            The second issue I had when listening to 3 chapter chunks was spoilers. If I got distracted during chapter 1 but not chapter 3, chapter 3 would contain spoilers for chapter 1 and chapter 1 would be spoiled on the re-listen :)

                                                            \n

                                                            Solution

                                                            \n

                                                            As it turns out listening in 1 chapter chunks solved both of these issues. So now I play one chapter on a loop until I feel I comprehend it well enough and then move to the next. This reduces the time when I need to re-listen because I was distracted and is simple because I only need to mess with the player when I'm ready to move to the next chapter.

                                                            \n

                                                            It also reduces the spoiler issue. While there are still spoilers, they are limited to spoiling the same chapter. A good enough compromise for me.

                                                            \n

                                                            As far as playback speed goes, I like to speed audio up when I can concentrate on the audio but prefer to listen at normal speed when I can't.

                                                            \n

                                                            Other considerations

                                                            \n

                                                            Some content might lend itself more to being broken into chunks by time rather than chapters. After all, not all chapters are the same length and podcasts don't usually have chapters. Assuming I decide to stick with this approach, I'll probably try running podcasts which require one to pay attention through a script that splits them up into chunks based on duration and treat those chunks as chapters in books.

                                                            \n

                                                            If you try this and find it useful and/or have modifications, by all means, share.

                                                            \n

                                                            Also, if this is a well known technique, feel free to make fun of me. It'll be fun listening to the comments being read on the community news show.

                                                            \n

                                                            This episode was processed using Audacity https://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the \"Truncate Silence\" effect with its default settings to minimize the silence between people speaking. When used with its default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.

                                                            \n

                                                            Intergraph Corporation is an American software development and services company. It provides enterprise engineering and geospatially powered software to businesses, governments, and organizations around the world. Intergraph operates through three divisions: Hexagon PPM, Hexagon Safety & Infrastructure, and Hexagon Geospatial. The company's headquarters is in Huntsville, Alabama, USA. In 2008, Intergraph was one of the 100 largest software companies in the world. In 2010, Intergraph was acquired by Hexagon AB. Intergraph was founded in 1969 as M&S Computing, Inc., by former IBM engineers who had been working with NASA and the U.S. Army in developing systems that would apply digital computing to real-time missile guidance. The company was later renamed to Intergraph Corporation in 1980. In 2000, Intergraph exited the hardware business and became purely a software company. On July 21, 2000, it sold its Intense3D graphics accelerator division to 3Dlabs, and its workstation and server division to Silicon Graphics. The companies incorporated SmartSketch, a drawing program used previously for the PenPoint OS and EO tablet computer. When Pen computing did not take off, SmartSketch was ported to the Windows and Macintosh platforms. https://www.cnet.com/news/intergraph-delivers-cheap-workstations/

                                                            CentOS (/ˈsɛntɒs/, from Community Enterprise Operating System) is a Linux distribution that attempts to provide a free, enterprise-class, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board. In July 2010, CentOS overtook Debian to become the most popular Linux distribution for web servers, with almost 30% of all Linux web servers using it. Debian retook the lead in January 2012.

                                                            \n

                                                            In January 2014, Red Hat announced that it would sponsor the CentOS project, "helping to establish a platform well-suited to the needs of open source developers that integrate technologies in and around the operating system". As a result of these changes, ownership of CentOS trademarks was transferred to Red Hat, which now employs most of the CentOS head developers; however, they work as part of Red Hat's Open Source and Standards team, which operates separately from the Red Hat Enterprise Linux team. A new CentOS governing board was also established.

                                                            \n

                                                            CentOS developers use Red Hat's source code to create a final product very similar to RHEL. Red Hat's branding and logos are changed because Red Hat does not allow them to be redistributed. CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms. CentOS version numbers for releases older than 7.0 have two parts, a major version and a minor version, which correspond to the major version and update set of Red Hat Enterprise Linux (RHEL) used to build a particular CentOS release. For example, CentOS 6.5 is built from the source packages of RHEL 6 update 5 (also known as RHEL version 6.5), which is a so-called "point release" of RHEL 6.

                                                            \n

                                                            Starting with version 7.0, CentOS version numbers also include a third part that indicates the monthstamp of the source code the release is based on. For example, version number 7.0-1406 still maps this CentOS release to the zeroth update set of RHEL 7, while "1406" indicates that the source code this release is based on dates from June 2014. Using the monthstamp allows installation images to be reissued for (as of July 2014) oncoming container and cloud releases, while maintaining a connection to the related base release version.

                                                            Since mid-2006 and starting with RHEL version 4.4, which is formally known as Red Hat Enterprise Linux 4.0 update 4, Red Hat has adopted a version-naming convention identical to that used by CentOS (for example, RHEL 4.5 or RHEL 6.5). AltArch releases are released by the Alternative Architecture Special Interest Group (AltArch SIG) to supporThere are three primary CentOS repositories (also known as channels), containing software packages that make up the main CentOS distribution: base - contains packages that form CentOS point releases, and gets updated when the actual point release is formally made available in form of ISO images. updates - contains packages that serve as security, bugfix or enhancement updates, issued between the regular update sets for point releases. Bugfix and enhancement updates released this way are only those unsuitable to be released through the CentOS-Fasttrack repository described below. addons - provides packages required for building the packages that make up the main CentOS distribution, but are not provided by the upstream. The CentOS project provides several additional repositories that contain software packages not provided by the default base and updates repositories. Those repositories include the following: CentOS Extras - contains packages that provide additional functionality to CentOS without breaking its upstream compatibility or updating the base components. CentOSPlus - contains packages that actually upgrade certain base CentOS components, changing CentOS so that it is not exactly like the upstream provider's content. CentOS-Testing - serves as a proving ground for packages on their way to CentOSPlus and CentOS Extras. Offered packages may or may not replace core CentOS packages, and are not guaranteed to work properly. CentOS-Fasttrack - contains bugfix and enhancement updates issued from time to time, between the regular update sets for point releases. The packages released this way serve as close candidates for the inclusion into the next point release. This repository does not provide security updates, and does not contain packages unsuitable for uncertain inclusion into point releases. CR (Continuous Release) - makes generally available packages that will appear in the next point release of CentOS. The packages are made available on a testing and hotfix basis, until the actual point release is formally released in form of ISO images. debuginfo - contains packages with debugging symbols generated when the primary packages were built contrib - contains packages contributed by CentOS users that do not overlap with any of the core distribution packages Software Collections - provides versions of software newer than those provided by the base distribution, see above for more details

                                                            In Linux, Logical Volume Manager (LVM) is a device mapper target that provides logical volume management for the Linux kernel. Most modern Linux distributions are LVM-aware to the point of being able to have their root file systems on a logical volume.

                                                            Heinz Mauelshagen wrote the original LVM code in 1998, taking its primary design guidelines from the HP-UX's volume manager. LVM is used for the following purposes: Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing. Managing large hard disk farms by allowing disks to be added and replaced without downtime or service disruption, in combination with hot swapping. On small systems (like a desktop), instead of having to estimate at installation time how big a partition might need to be, LVM allows filesystems to be easily resized as needed. Performing consistent backups by taking snapshots of the logical volumes. LVM can be considered as a thin layer of continuity and ease-of-use for managing hard drive replacement, repartitioning and backup. software layer on top of the hard disks and partitions, which creates an abstraction Basic functionality Volume groups (VGs) can be resized online by absorbing new physical volumes (PVs) or ejecting existing ones. Logical volumes (LVs) can be resized online by concatenating extents onto them or truncating extents from them. LVs can be moved between PVs. Creation of read-only snapshots of logical volumes (LVM1), or read-write snapshots (LVM2). VGs can be split or merged in situ as long as no LVs span the split. This can be useful when migrating whole LVs to or from offline storage. LVM objects can be tagged for administrative convenience. VGs and LVs can be made active as the underlying devices become available through use of the lvmetad daemon.

You have to click and know a little about what you doing. For me with the basic 500GB install disk I got only a bare server with ssh. The machine was having power issues and would not boot from a usb stick so I had to go through 4 different DVD drives until I found one that worked with the DVD-R format. I had to use another deskop and power the DVD threw the other desk up connecting only the sata port the IDE drive was not working well either on this old board.

I also used export_proxy= to get it work globally. I had really trouble finding a fast mirror but I did not give up hope after a while it found fast mirrors that I got over 2MB per second from.

                                                            This is the fourth show about the Bash functions I use, and it may be the last unless I come up with something else that I think might be of general interest.

                                                            \n

                                                            There is only one function to look at this time, but it's fairly complex so needs an entire episode devoted to it.

                                                            \n

                                                            As before it would be interesting to receive feedback on this function and would be great if other Bash users contributed ideas of their own.

                                                            This solution probably won't work for you, because none of the ones I found on the Internet worked for me. Trial and error led me here, and it's probably the only guide you'll have as well.

                                                            Start with as high a quality audio file as you can manage. .wav is good, but it's big. Let's convert it to .flac. If you already have a .flac file, skip this part.

                                                            1.) Convert .wav to .flac.

                                                            \n
                                                            sox INPUT.wav OUTPUT.flac
                                                            \n

                                                            2.) Convert the .flac to a very small mono .opus. Bitrate can be even smaller. I went down to 14.

                                                            \n
                                                            opusenc --bitrate 18 --downmix-mono INPUT.flac OUTPUT.opus
                                                            \n

                                                            3.) Combine the .opus file with a single static image, and output to a .webm video. This should not be very much bigger in file size than the .opus and .jpg combined. The smaller the image file, the better. (I tried using a .gif, but it was actually bigger than the .jpg I ended up with.)

                                                            \n
                                                            ffmpeg -i INPUT.opus -r 1 -loop 1 -i INPUT.jpg -c:v libvpx -tune stillimage -shortest -y -c:a copy OUTPUT.webm
                                                            \n

                                                            The final file. It doesn't sound great, but it's listenable, which is all that was desired.

                                                            \n

                                                            I have a number of Raspberry Pis -- possibly too many -- and I sometimes lose track of which is which, what model, size, name, address each one is. I wanted to be able to keep an inventory of them all, and to this end I wrote myself a little script that can be run on any Pi which will report useful information about it.

                                                            \n

                                                            Every Pi has a unique serial number. Actually it's randomly generated so there may be a few collisions but it's close to unique! It also contains a revision number which encodes various items of information about it such as release date, model, PCB revision and memory. My script decodes this revision number for you based on a published table.

                                                            \n

                                                            I run a Wikimedia instance on a Pi and have used this script to record details of my Pis there as well as what they are being used for and any planned projects. I now feel more organised!

                                                            If you want to hold private conversations with another party over radio then perhaps amateur radio is not for you as this goes against the whole principle of Amateur Radio.

                                                            \n

                                                            Listening to amateur radio broadcasts is actively encouraged, and in the UK a licence is not required for listening.

                                                            \n

                                                            A simple receiver capable of listening to sideband broadcasts and odd bit of long wire is all that's required.

                                                            \n

                                                            In the past it was common to hear an Amateur operator saying goodbye to any short wave listeners at the end of their conversation. If you listen carefully at about 10 minutes in the station DF2BO says goodbye to anybody still listening.

                                                            The thinking is that if you are considering which tags to add to a show without them you can look through this list to find out whether other people have used the tag and in what context.

                                                            How I Got Into Podcasting

                                                            \n

                                                            The Background

                                                            \n

                                                            Audio production has always been an interest of mine: my late grandfather was an audiophile, my dad ran an AV studio in Woking (the one where the Spice Girls were formed - my dad got mentioned in a couple of their autobiographies) and now runs his own AV consultancy business, and my cousin also runs an AV consultancy... so there’s a definite family history in there.

                                                            \n

                                                            I dabbled briefly with hospital radio (as a technician, rather than a presenter) in the late 80’s, and I was a technician and presenter on College Radio in the early 90’s where I hosted a show called “The Barry Manilow Fan Club” on Friday lunchtimes.

                                                            \n

                                                            Yes, I am a huge fan of Barry Manilow - he’s given me a lot of inspiration as a musician - no, I didn’t play any Barry on the College Radio show.

                                                            \n

                                                            I’d also had a few people say that I had a good radio voice. Others say a good radio face, but I don’t like them anymore.

                                                            \n

                                                            The Catalyst

                                                            \n

                                                            In 2007, I discovered this podcasting lark through a couple of friends who had their own podcasts. One was The Random Three: a personal musical journey where Mark - the host - would play three seemingly-random pieces of music from his own collection (thus, not podsafe) and explain the reasons why he chose them. Most of the time, these seemingly-random tracks actually had a theme, but it didn’t necessarily become apparent until after the second track. It was a great show - now sadly defunct - and I really miss it. I even submitted my own music choices for Mark to present.

                                                            \n

                                                            The other was Dumbed Down Life: three chaps nattering about “stuff” and playing some music along with it. Another great show, which - although it still exists - currently releases episodes every year or so.

                                                            \n

                                                            What drew me to these shows - apart from being friends, was the fact that these were regular guys, not professionals.

                                                            \n

                                                            That led me to think “I can do that”, so I set about proving - to myself, mostly - that I could.

                                                            \n

                                                            The Start

                                                            \n

                                                            One Thursday in early March 2008, when the wife had gone to the gym for a couple of hours, I grabbed my Logitech headset, my Linux laptop, a handful of tracks from the Podsafe Music Network, and a piece of software called IDJC, and recorded the first ever episode of The Bugcast. It was just over 22 minutes long, and it was dire. Utterly dire. Every so often, I go back to it and listen and cringe and marvel at how much better the show is now!

                                                            \n

                                                            The music back then wasn’t strictly podsafe either: the first track I played was Moloko’s Sing It Back… but I didn’t worry about it then, as I got the track from a source that gave implicit permission for use in podcasts.

                                                            \n

                                                            I did do a show - episode 20 - which was a nostalgic trip back to my college years, where I played tracks by Chad Jackson, Japan, and Dream Warriors. This was a complete and intentional violation of copyright on my part, which led me to pull the show only a few weeks later. I did rerelease the show two years after that, but with the offending tracks removed. However, there is a story to the show, so I would recommend you go listen.

                                                            \n

                                                            Back then, it was just me and a small listener-base of friends, their family, their families’ servants; their families’ servants’ tennis partners, and some chap I bumped into in the mess the other day called Bernard. But as time went on and I got more experience, I was really enjoying what I was doing, and started to experiment.

                                                            \n

                                                            One thing I did discover by about episode 16 is that I wasn’t editing my shows in post, aside from topping and tailing silence. This made it so much easier for me as I was recording the shows as-live from the very beginning, but taking out the vocal gaps, gaffes and the like. So there was really only one place to go from there...

                                                            \n

                                                            Going live

                                                            \n

                                                            So in August 2008, on episode 24, to an audience of about 10 people, I streamed the first LIVE episode of the podcast. Wow, that was such a buzz! It was a major turning point in the show as I committed myself to do a regular show at a set time each week... turning a fun hobby into something a little step beyond amateur. There were a couple of non-live shows that I had to put together using the wife’s Windows machine when my laptop went bang and had to be repaired, but I hated doing that because I didn’t like the piecemeal sticky-tape method of production. There was little flow, and my spoken links between the music sounded very much like a bad Radio 4 anchor.

                                                            \n

                                                            In late September 2008, I was accepted as a member of the now-defunct Association of Music Podcasting. This was another major step for me. All member of the Association were peer-reviewed as part of the criteria for membership. This meant that my podcast was sufficiently good to be accepted. That meant so much to me, and made me take things so much more seriously (and was the main reason why I pulled episode 20 just prior)

                                                            \n

                                                            It also meant that the show was becoming more music-oriented - something I really did not have a problem with! Particularly as I was starting to strike up good relationships with some of the artists that I was featuring on the show. This led to me prerecording an interview with one of the bands in January 2009, and then again with another artist in March.

                                                            \n

                                                            Having registered a proper domain for the podcast (rather than piggybacking my own personal domain) and then celebrated the first anniversary of the show... you could say that the show was fuelling its own progression. And I was enjoying that journey immensely!

                                                            \n

                                                            Over the next 6 months, I joined the Made In The UK Show collective, interviewed an artist LIVE on the show, had the show syndicated on an internet radio station in the UK, and launched a new, independent chatroom for the website.

                                                            \n

                                                            The Major Change

                                                            \n

                                                            And then, in September of 2009, the 18 month anniversary of the show, and two days before my birthday, something happened to totally turn the show upside down.

                                                            \n

                                                            I decided that I wanted to improve the show. Bearing in mind that I was still using my Logitech headset, my Linux laptop, and a piece of software called IDJC to record and stream the show, I felt it was time for a change. So I spent a small fortune on a mixer, microphones, stands, audio interface, and cables.

                                                            \n

                                                            Yes, microphones. Plural.

                                                            \n

                                                            Up to this point my wife, Caroline, had progressed from occasional listener, to regular distraction (I don’t think details are appropriate!), to researcher. So I asked her a question... if I bought two microphones, would you join the show as a permanent co-host? She said yes.

                                                            \n

                                                            That really changed things. The dynamic of me talking to an imaginary audience (bar the activity in the live chatroom) changing to me bouncing off someone in the same room was electric! The show was totally transformed by that fairly simple change. Our listener figures jumped up, the music on the show was more varied, existing listeners enjoyed the show more... it was amazing.

                                                            \n

                                                            There have been occasions where Caroline hasn’t been able to join the show (illness, kids, etc) and the listeners (and I) have really noticed her absence.

                                                            \n

                                                            This episode was processed using Audacity https://audacity.sourceforge.net. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It has been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.

                                                            \n

                                                            Next we use the "Compressor" effect with the following settings:

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the "Truncate Silence" effect with its default settings to minimize the silence between people speaking. When used with its default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying "uuuuummmm." Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too agressively your audio may sound sped up and choppy.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can "Mix and Render" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being "crashy" but if you remember save after every major transform, you will wonder how it even got that reputation.

                                                            Start with one zone at a time and raise/test sensitive KISS...don't setup like 4 zones and expect to trouble shoot anything. I used my Android to do a lot of tweaking. I also want to sort out "night" mode config so after night mode kicks in a different config is automatically applied.

                                                            \n

                                                            Use low quality for motion detection and drop frame rate of cam to lower than max of ZM for little to no smearing and I also set "Alarm Frame Count to 2" and "overload ignore frame count to 4" but I think it's more about Alarm Frame Count..I can't be sure..

                                                            For sudden changes to the environment, no better tool then Overload Frame Ignore Count. Your fps determines these settings but at 10 fps with Overload Frame Ignore Count set to 4, it only ignores .4 seconds. In other words if a drastic change to the lighting (such as a car with headlights on in darkness) passes within the monitors view it will ignore the number of frames you specify before processing for motion detection.

                                                            \n

                                                            Alarm Frame Count

                                                            \n

                                                            This option allows you to specify how many consecutive alarm frames must occur before an alarm event is generated. The usual, and default, value is 1 which implies that any alarm frame will cause or participate in an event. You can enter any value up to 16 here to eliminate bogus events caused perhaps by screen flickers or other transients. Values over 3 or 4 are unlikely to be useful however. Please note that if you have statistics recording enabled then currently statistics are not recorded for the first ‘Alarm Frame Count’-1 frames of an event. So if you set this value to 5 then the first 4 frames will be missing statistics whereas the more usual value of 1 will ensure that all alarm frames have statistics recorded.

                                                            By default ZoneMinder saves events as a sequence of images. It is however possible to save an event as a video file. Caution is advised when converting events to video as it is very strenuous on the ZoneMinder machine, however once you have converted an event it can be viewed/downloaded any time without additional stress on the server.

                                                            First, make sure you have OPT_FFMPEG under Options -> Images set to yes (checked).

                                                            \n

                                                            If necessary, set the proper full path for the ffmpeg executable in PATH_FFMPEG (ex.: /usr/bin/ffmpeg)

                                                            \n

                                                            Open up the default view for an event and Click the video link located in the top left corner

                                                            \n

                                                            Choose a video export file type and click generate.

                                                            \n

                                                            Download the video to your machine. If video files have already been generated you will see them listed at the bottom of the page.

                                                            \n

                                                            When an event gets a video file encoded for it you can choose to automatically include that event with any future exports.

                                                            1. Backed up my home directory, just in case.

                                                              2. \n

                                                            2. Replaced the hard drive.

                                                            3. Tried to boot from Lenovo Windows thumb drive.

                                                            4. Found that the BIOS was set to legacy mode, so reset BIOS to factory.

                                                            5. Told the installer to use the entire drive.

                                                            6. Went through the entire Windows install and update process.

                                                            7. Used the instructions provided by Mongo to resize Windows filesystem size.

                                                            8. Used the instructions provided by Mongo to turn of fast boot.

                                                              9. \n

                                                            9. Used the instructions provided by Mongo to turn of Secure Boot in BIOS.

                                                            10. Booted from Xubuntu 16.04 thumb drive.

                                                              11. \n

                                                            11. Did Xubuntu install as normal, choosing the install type of installing along side Windows Boot Manager.

                                                              12. \n

                                                            12. Installed all of the updates.

                                                              13. \n

                                                            13. Mounted the old hard drive with a USB drive enclosure, which was a bit of a challenge because that drive was encrypted. The drive has 2 partitions. A small boot partition and then a large LUKS encrypted partition.

                                                              \n

                                                              This is a procedure that can be used to mount such a partition.

                                                              \n
                                                                \n

                                                              • First you must decrypt the partition and map it to a device. This can be done with the following command (assuming the partition mount point is /dev/sdb2):

                                                                \n
                                                                cryptsetup luksOpen /dev/sdb2 cryptdrive
                                                                \n

                                                                This command will map the partition to the following device:

                                                                \n
                                                                /dev/mapper/cryptdrive
                                                                • \n

                                                              • Normally you could then mount the filesystem as follows:

                                                                \n
                                                                mount /dev/mapper/cryptdrive /mnt
                                                                • \n

                                                              • However, in this case the encrypted filesystem is actually an LVM volume that contains two volume groups that made up the partitions of the previous Linux install, so you can't directly mount it.

                                                                • \n

                                                              • I had to first install the LVM tools, which had not been installed by default.

                                                                \n
                                                                apt-get install lvm
                                                                • \n

                                                              • Then I had to issue the following command to activate the LVM volume groups.

                                                                \n

                                                                That resulted in two more devices being created.

                                                            Over the period 40 shows missing tags and/or summaries have been made whole.

                                                            If you would like to contribute to the tag/summary project visit the summary page at https://hackerpublicradio.org/report_missing_tags.php and follow the instructions there.

                                                            \n

                                                            The summary page has been further enhanced this month. The list of tags at the end of the page has been laid out to show the blocks with the same starting letter, and an alphabetic index added at the front. It is hoped that this will make it easier to find tags relating to the show to which you are about to add tags.

                                                            Andrew suggests that we may be able to record or even stream audio from the Podcrawl. Dave apparently is an expert in such things, and tries to impress the others with science. Kevie suggests we wait towards the end of the event when it's quieter.

                                                            \n

                                                            Andrew keeps Ken Fallon happy by suggesting that listeners record a response to this show with any suggestions about recording at live events.

                                                            This is an update to hpr1877 :: Recording HPR on the fly on your Android phone. I thought that was two years ago, but wow it's even two and a half years ago, back in late 2015.

                                                            \n

                                                            Updated recommendation! Back in #1877 I said that you could go with this app because it has these nice functions, or with that app because it has these other things. Well, there's no longer any need for trade-offs. Just go to f-droid, install \nAudio Recorder and you're good to go!

                                                            \n

                                                            I installed it in two minutes, recorded a two-minute episode on how great it seems to be, and then I recorded another three episodes and I can confirm that it's pretty great. You've got the record/pause control available on the lock screen, it can save in FLAC, you can define the naming pattern it should use for the files, and you can tell it where to store its files.

                                                            \n

                                                            Some apps just insist on saving everything in internal storage, and that can run out pretty quick. Meanwhile I've got 30 GB left on my SD card that I'm struggling to make apps make use of.

                                                            \n

                                                            And finally, it also has a rename function (unlike my previous recommendation uRecord!), so you can conveniently, right in the app without finding the files through some other means, change the file name to reflect what it was that you were recording, so that you're not in the situation where one month later you're looking at a dozen files with just dates and times and need to listen to all of them to figure out which one it is you want.

                                                            \n

                                                            It even has an automatic skip silence function, but that's pretty useless for the places I record in. :-D

                                                            \n

                                                            When I said \"cool waveform\" I meant that it's displaying the recorded waveform on the screen as it records. Not that useful, but it's just part of the overall really nice polish of the app.

                                                            TL;DL: We have two directories, two git repos. He doesn't have to know about git. He plays around in the staging directory first, looks at the test site how it turned out, when he's happy he just copies the files over to the production directory and they go live. SparkleShare automatically pushes to gitlab.com (I didn't say it outright in the episode, but yeah, I'm using the hosted service -- that's basically the point of this mode of doing things, minimal setup, responsibility and maintenance for me), and GitLab CI runs Jekyll (use the static site generator of your choice) to copy files over for deploying, and finally GitLab Pages deploys the new site.

Some of what I did to prepare the notes was to cut and paste information from YouTube pages, but the basic list itself was generated programmatically. I thought the process I used might be of interest to somebody so I am describing it here.

                                                            \n

                                                            Components

                                                            \n

                                                            I needed four components to achieve what I wanted:

                                                            \n\n

                                                            I will talk a little about the first three components in this episode in order to provide an overview.

                                                            \n

                                                            The full-length notes (available here) contain details of the processes involved in building the list of channels.

                                                            In the beginning there was Cygwin, by Cygnus Solutions (later acquired by Red Hat), then came msys, a lightweight derivative with no package manager, no fancy integration tools, just the bare minimum necessary to support a gcc compiler and the GNU autotools.

                                                            \n

                                                            msys2 is cygwin minus the package manager plus an adaptation of the pacman package manager from Arch, and a big archive of packages of all kinds. It offers a friendlier command-line experience than Cygwin does.

                                                            I failed to mention here that msys was explicitly made to support the MinGW (Minimalist GNU for Windows) flavor of GCC, which is intended for building native Windows applications. GCC for Windows has two types of output, cygwin or mingw, where cygwin is for source code that expects POSIX-y facilities and mingw is for code that should compile (possibly with some minor adjustments for C dialect) equally well under GCC and Microsoft Visual C, and should produce about the same output.

What advantage, if any, does so-called "head-hopping" have, over focusing on a single character at a time? Why is it sometimes better to do the opposite? And how can these different construction elements impact the story as a whole?

You still just stow mything, stow -R mything and stow -D mything like you always did.

                                                            I am currently in the process of converting our website from Hugo to Styx.

                                                            Styx is s static site generator written entirely in the Nix language. It is able to figure out exactly what pages need to be rebuilt depending on what you changed in your page source and data sources, and all intermediate results are stored in the Nix store.

                                                            The parsing of AsciiDoc and (multi)Markdown is done by external tools, but the templating and layouts is all Nix.

                                                            I thought I may have dreamed the bit about carnix or buildRustPackage parsing TOML within Nix, because I couldn’t find any evidence of them ever having done that. But then I discovered it was in nixpkgs-mozilla I had seen it! That’s Mozilla’s overlay for nixpkgs, which makes Rust Nightly always available in Nix, so it’s kind of Nix’s rustup equivalent. So yeah, I guess I had dreamed who did it, but not that somebody did it. :-)

                                                            \n

                                                            This is the first episode of a series about the English language. In it I want to look at some of the problems people (including myself) have with it. I plan to do several episodes and I want to keep them short.

                                                            \n

                                                            The English language is old and has changed – evolved – in many ways over the years. It has come from a multitude of sources, and it's difficult to say what is correct in an absolute way.

                                                            \n

                                                            For example, when I was at school we were taught that "nice" should not be used in written material. At that time it was becoming common to see phrases like "I had a nice time" meaning pleasant (in a bland sort of way). In my "Concise Oxford Dictionary" from 1976 the 6th definition, "agreeable" is marked "colloquialism", whereas today this is a common usage.

                                                            \n

                                                            However, it's easy to use the wrong word in the wrong context. You might choose one that sounds similar for example. You might also have problems with the spelling of a chosen word. Spelling in English is not always logical. You might also find yourself confused about the use of punctuation – the correct use of apostrophes can be challenging for example.

                                                            \n

                                                            In this series I want to examine some of the problem areas and try to give you the means of remembering the right way.

                                                            On Android, I'm lazy and just seem to have fallen into using the chrome browser. The Add-on I'm going to talk about unfortunately isn't available for the Android operating system.

                                                            On the Linux desktop, I use Firefox

                                                            \n

                                                            In the past, I've dabbled with various browser add-ons but until very recently I've been using no browser add-ons on the desktop.

                                                            \n

                                                            A browser add-on I did use and did miss was Tab groups

                                                            \n

                                                            Tab Groups was originally a feature built into Mozilla Firefox

                                                            \n

                                                            The feature was removed but maintained as an add-on until it was broken by changes in Firefox 57

                                                            \n\n

                                                            A colleague at work brought the One-Tab add-on to my attention https://www.one-tab.com/

                                                            \n

                                                            It's available for both the Chrome browser and Firefox

                                                            \n

                                                            No sign-up or registration required

                                                            \n

                                                            With Tab-group I found myself spending a lot of time arranging groups getting the size right naming them etc.

                                                            \n

                                                            One tab philosophy is a bit different and perhaps maybe not so intuitive, though I think now after some use I prefer it as it gets out of the way and can be used with the minimal of fuss.

                                                            \n

                                                            I highly recommend one-tab if you regularly find yourself dealing with a lot of open tabs in your browser.

It also addresses the export of personal data outside the EU. The GDPR aims primarily to give control to citizens and residents over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU. It was adopted on 14 April 2016, and after a two-year transition period, becomes enforceable on 25 May 2018.\n\n\n

                                                            \n
                                                            a) processed lawfully, fairly and in a transparent manner in relation to individuals;
                                                            \n
                                                            b) collected for specified, explicit and legitimate purposes and not further processed in a manner that is incompatible with those purposes; further processing for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes shall not be considered to be incompatible with the initial purposes;
                                                            \n
                                                            c) adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed;
                                                            \n
                                                            d) accurate and, where necessary, kept up to date; every reasonable step must be taken to ensure that personal data that are inaccurate, having regard to the purposes for which they are processed, are erased or rectified without delay;
                                                            \n
                                                            e) kept in a form which permits identification of data subjects for no longer than is necessary for the purposes for which the personal data are processed; personal data may be stored for longer periods insofar as the personal data will be processed solely for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes subject to implementation of the appropriate technical and organisational measures required by the GDPR in order to safeguard the rights and freedoms of individuals; and
                                                            \n
                                                            f) processed in a manner that ensures appropriate security of the personal data, including protection against unauthorised or unlawful processing and against accidental loss, destruction or damage, using appropriate technical or organisational measures.
                                                            \n
                                                            \nArticle 5(2) requires that:\n
                                                            \n
                                                            the controller shall be responsible for, and be able to demonstrate, compliance with the principles.
                                                            \n

                                                            What information does the GDPR apply to?

                                                            \n

                                                            The GDPR applies to ‘personal data’ meaning any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier.

                                                            \n

                                                            Special category data is personal data which the GDPR says is more sensitive, and so needs more protection.

                                                            The Data Protection Bill deals with this type of data in a similar way to special category data, and sets out specific conditions providing lawful authority for processing it.

                                                            You can only process personal information if you have:

                                                            2. Contract: the processing is necessary for a contract you have with the individual, or because they have asked you to take specific steps before entering into a contract.\n
                                                            3. Legal obligation: the processing is necessary for you to comply with the law (not including contractual obligations).\n

                                                            6. Legitimate interests: the processing is necessary for your legitimate interests or the legitimate interests of a third party unless there is a good reason to protect the individual’s personal data which overrides those legitimate interests. (This cannot apply if you are a public authority processing data to perform your official tasks.)\n

                                                            I chopped the recording down a bit as it was originally over an hour long I thought it would just be too monotonous.

                                                            \n

                                                            Listening back to the recording I can't believe it took me so long to get organised and get out the door.

                                                            With all the rhythmic clinking sounds it sounds more like I'm riding a horse than walking the dog, I think the supplied clip-on Dictaphone microphone is a bit on the sensitive side.

                                                            As a responsible dog walker, one of the most important pieces of equipment I take with me on every dog walk is the “Toley Bone” mentioned around one minute point.

                                                            \n

                                                            Toley is a fine Scottish word, you can look it up if you are unfamiliar with it https://www.firstfoot.com/dictionary/t.html or alternatively just do a simple google search to be enlightened.

                                                            Listen out for the crinkling sound around the halfway point where it is put to good use.

                                                            \n

                                                            The second most important piece of kit is a sweet, consumed around the 3 minute point.

                                                            \n

                                                            The main part of the walk was fairly uneventful and consisted of traffic noise, passing by the local bus terminus where the bus turns at the end of its route, a rather noisy motorbike and a brief encounter with a fellow dog walker on route.

                                                            \n

                                                            Finally ending with a treat and some light refreshment.

                                                            \n

                                                            Oh, and in case you're wondering yes the the scones mentioned near the end of the podcast made by Mrs X were wonderful.

                                                            \n

                                                            Oh and one final thing on listening back to the recording one more time I just realised that for some unknown reason just after the bus noise I started whistling very softly to myself, I don't remember doing that at all, I must have been doing it subconsciously. I could be wrong but it sounds to me like I'm whistling the tune “The animals march in two by two” I guess it was just the right tempo to help me round my one hour walk.

                                                            \n

                                                            People need to save for retirement. But how do we do that?

                                                            \n

                                                            Conventional wisdom in the USA says that Social Security is your retirement fund.

                                                            \n

                                                            There's no guarantee that will still be around when you retire, and it's entirely out of your hands. It maybe a good bonus, but possibly it isn't something to rely on.

                                                            \n

                                                            So how do we do it?

                                                            \n

                                                            They don't teach you this stuff in school

                                                            \n

                                                            People say you should save for retirement, but they forget to say how.

                                                            \n

                                                            Currently, there are two de facto methods of funding retirement in the USA:

                                                            \n
                                                              \n
                                                            • social security: abstract, not guaranteed. Assumes you start contributing to ssn early
                                                              • \n
                                                            • 401k. abstract, indirect unless you take active role in tracking it. best if you start early.
                                                              • \n
                                                            \n

                                                            In other countries, there may be significant alternatives. For instance, Kiwisaver in New Zealand.

                                                            \n

                                                            These methods are OK, but difficult for you to interact with directly.

                                                            \n

                                                            There are two direct levels of investment:

                                                            • Go to your bank, ask to invest in a mutual fund or Certificate of Deposit (CD)

                                                            \nSo the LinuxLUGcast is an open podcast/LUG that meets every first and third friday of the month using mumble. This method of running a podcast leaves it open to anyone showing up (which is what we want because it gets difficult for fiftyonefifty and I to come up with topics all the time). We have also gotten the reputation of being a safe for work podcast. This is why episode 102 is being posted here. Between the not safe for work language and the fact that after a few drinks during the podcast I get a little rambly we thought it best not to publish it on the regular LinuxLUGcast feed, but I thought there was some good conversation here that would be lost if it did not go somewhere. After some discussion we at the LinuxLUGcast decided that we would publish it here so that it could be heard by the HPR community.\n
                                                            \nWe have also done some website remodeling which has screwed up the .ogg feed, and wanted to let people know that we are still podcasting and to please check out\nhttps://www.linuxlugcast.com/ for the new .ogg feed.\n

                                                            Ubuntu Mate 18.04

                                                            Good day to all you HPR Listers. Sorry that its been a while since I recorded a show, but as they say life has got in the way over the last few months, and I've spent quite a bit of it away from the home front.

                                                            \n

                                                            As it happens on one of those trips away my laptop running Mint Mate 18.3 LTS, based on Ubuntu 16.04LTS decided that it wouldn't boot as it didn't recognise my account, and as I had not created a Root account I could not sign in and fix the issue, which was a corrupted configuration file in the users folder.

                                                            \n

                                                            As luck would have it I had just downloaded the latest Ubuntu Mate 18.04 .iso to try it as a live disc, so I had a boot disc that I could use to boot the laptop and access the data to rescue all my important information which was mainly all my emails and my browser settings and bookmarks, as this is one of my travelling laptops not much of importance is permanently stored on it, so it didn't take long and I was ready to reinstall the OS to the PC. Just in case I had missed some important data on the current SSD, as I had a spare SSD with me in the bag, yes I'm geeky enough to carry a spare SSD or 2 in the bag. So I dug it out and installed it into the PC, which by the way is a Dell Latitude E6540 with an i5 dual core mobile chip with hyper-threading. It's currently running 4Gig DDR3 RAM but can run up to 16Gig in the 2 slots it has.

                                                            \n

                                                            So I booted the laptop with the USB boot disc I had created and as with all recent Ubuntu releases you get a screen asking if you want to try or install the OS, as I needed a working PC I went straight to the install option. For those not familiar with Linux or Ubuntu, the installer is a joy to use and very friendly to new users. As this was a first install to this SSD the only option I had was a full install which I chose, then was asked if I wanted to do the default install which partitions the drive and installs the bootloader automatically without any further need for intervention or did I want to do a custom partition arrangement. As the default is adequate for my needs I chose this and clicked continue. During this process you also get the option of a minimal or full installation, the minimal installation gets you a running PC with the basic utilities and leaves you to chose what to install later, but as I use the software that would be omitted I chose the full install. You get asked a final time if you are sure you want to install, with a warning that all current data on the disc will be wiped, as I was happy I clicked proceed. At this point the install starts and you are taken through setting up your PC configuration for language, keyboard, and user account. By the time I had completed this, the install was half completed and the whole process took less than 15 minutes.

                                                            \n

                                                            After the install is complete you get the message to reboot the PC and eject the boot media to reboot into the new install, on first boot you will either be presented with the login screen or go straight to the desktop depending on the choices you made during the install. Once you are at the desktop for the first time you are presented with a wallpaper of the Ubuntu Mate logo and 2 panels one at the top and one at the bottom of the screen. The top one has for those more traditional Linux and Windows users all the information you would expect on the lower panel, such as the menu, notification area etc. As I'm more traditional in my use of a PC I quickly set up the lower panel with the Advanced Mate Menu and other notification apps such as network, clock and calendar and then deleted the other panel, but obviously this is a personal preference - go with what you find comfortable.

                                                            \n

                                                            The next step after connecting to the local WiFi was to install any updates, which despite this release only being a few days old there were a few, but this didn't take long and in less than an hour, which included backing up and swapping out the SSD I had a fully working laptop running Ubuntu 18.04 Mate.

                                                            \n

                                                            So there are a few bits of software not included by default in Ubuntu which I use regularly, one of which is synaptic so I opened the terminal and a sudo apt install synaptic later I had the package manager on the PC. You may ask why, but the software Boutique doesn't seem to have all the software available in the repositories and I don't always know the appropriate name of software I'm looking for to use the terminal all the time, so synaptic is a tool I use a lot. The next software that gets installed is Audacity as I use this for editing audio and sometimes extracting the audio stream from videos of the internet, most importantly for HPR listeners it is what I use to record and edit my HPR shows.

                                                            \n

                                                            So back to Ubuntu 18.04 Mate, I've been running it for a month on the laptop and about 3 weeks on my main box and as you would expect from a LTS (long term support until 2023) it's very solid and stable, I had a glitch transferring my e mails into Thunderbird on my main box, it had worked flawlessly on the laptop, so I ended up having to reinstall from scratch and on the second install it went perfectly, I think it was down to the way I set up Thunderbird which screwed things up, not the OS, but it's all fine now and I didn't lose anything in the process. For me coming from Mint there are a couple of utilities the Mint developers have implemented that are not available in Ubuntu, but nothing I can't work around. Saying that, if there are any Ubuntu developers out there, the Mint USB drive formatter and USB boot disc creation utilities are nice and simple to use but not available in the Ubuntu repositories.

                                                            \n

                                                            Obviously I've only had limited time to get to use the new OS but so far it doesn't seem too bad coming back to the mother ship so to speak from several years of using Mint Mate, virtually since its inception, but as I record this there has been nothing that has made me feel I need to rush and reinstall Mint, so I'll continue with Ubuntu Mate 18.04 at least until the new Mint19 based on this Ubuntu release comes out.

                                                            Introduction

                                                            \n

                                                            I have been thinking of buying a 3D printer for a year or so. I had thought of getting a Prusa i3 MK3 in kit form, but although it's cheaper than the built form this printer is not cheap, and I doubted my ability to build it. I was also unsure whether there was a real need for the capabilities of a 3D printer in my life, and whether such a purchase was justified.

                                                            \n

                                                            I had noticed the Chinese Creality CR10 printer in the recent past, and wondered about buying one of these at about half the price of the Prusa. This is a good-sized printer which comes fully-assembled as I understand, and it has had many good reviews.

                                                            \n

                                                            When the Creality Ender 3 was released in April 2018 for around half the price of the CR10 it looked worth the risk to see if I really needed a 3D printer. So I bought one (from Amazon) in June.

                                                            \n

                                                            As I write this (2018-06-10) it's been less than a week since it was delivered, so this is a very preliminary look at the printer.

                                                            There has been a change to the HPR workflow this month:

                                                              \n

                                                            • Earlier in 2018 a change was made to the database to add an additional version of the host name. This is intended to be spoken by espeak and can hold an alternative spelling which espeak handles better in the audio preamble of shows. In this way the name 'thelovebug', for example, which espeak renders as "Thel Ove Bug" can be stored as 'TheLoveBug', which espeak pronounces correctly.

                                                              • \n

                                                            • The use of this field has now been incorporated into the workflow.

                                                            • Many of these "espeak names" were changed in the database, but we probably haven't catered for them all. If your name is being mispronounced by espeak let us know and we'll try and fix it.

                                                            Greetings Hacker Public Radio listeners, Tony Hughes again coming all the way from Blackpool in the North West of the UK. Originally this show was going to be about some new kit that I have recently bought at my favourite computer auction. However as luck or actually bad luck should have it I fried the power supply on my Desktop machine yesterday as I was setting it up again after moving back to my office.

                                                            \n

                                                            The PC is a HP Compaq Elite 8300 micro Desk top tower with a i7 3rd generation 3770 3.4Ghz CPU and since upgrades now has 16Gig Ram and a Primary 256Gig SSD. This is my daily driver and I've been running it for a couple of years since I bought it at the said auction. It is the best PC I've ever owned; the full specifications are here:

                                                            \n

                                                            https://www.cnet.com/products/hp-compaq-elite-8300-cmt-core-i7-3770-3-4-ghz-4-gb-1-tb-b2d12utaba/specs/

                                                            \n

                                                            As I said I was re setting up my full rig after moving it back to the office upstairs after a temporary move while we had a house guest. As I was plugging in the power cable there was a flash and crack, and a few expletives were uttered, sure enough when I switched of the power at the plug and reconnected the power cable and then tried to power on the PC, it was dead. I was hoping that it was the power supply that had blown and as I had a spare I was not too concerned. However on investigation HP have done the dirty with the design of the motherboard and power supply and neither are standard ATX configuration, yes propriety hardware for this baby.

                                                            \n

                                                            I was lucky as a few months ago I had picked up a i3 HP using the same case, so I pulled out the power supply from this and fitted it into the i7 PC and luckily that did turn out to be the issue, and the PC sprang into life when I hit the power button. I’m now left with a PC that works, but another one that unless I can find a power supply to match is next to useless except for spares.

                                                            \n

                                                            Lessons learned, never connect the power cable when the socket is live, if your plug socket doesn't have a switch connect the kettle end to the PC first to reduce the risk of a short like mine. Also never assume that 2nd hand PC’s are standard case/motherboard format as you may have a problem sourcing spares if anything goes wrong as in my case. It’s not the first PC disaster I've had over the years and I can as in this case usually get round them, although not when I bricked the BIOS on a Lenovo x200 one time trying to clear a BIOS password, again I was left with a box of spares which actually came in very handy.

                                                            \n

                                                            Well that's the end of my tale of woe. I’ll do another episode on the recent trip to the auction and my new laptops shortly. This is Tony Hughes for Hacker Public Radio signing off for now.

Well, as you heard on my last episode I recently visited the computer auction I frequent here in the UK. If you want to drool over the catalogue at any time their website is here:

                                                            \n

                                                            I had also picked up some 240Gig SSD's and had planned to upgrade the storage but this is not possible with a 2.5 inch drive as it doesn't have a bay for this format. However it does support up to 128Gig High capacity SD cards so this could be an option if you don't want to go to the expense of upgrading the mSATA drive, however as luck would have it one of my other purchases had a 256Gig mSATA drive in a 2.5 inch caddy so that was quickly swapped out and both laptops got an upgrade. More of that in another show.

                                                            \n

                                                            So after doing the hardware upgrade I proceeded to install Ubuntu 18.04 MATE onto the PC. The install worked flawlessly and after completion and configuring the machine to my liking everything seems to be working just fine. The battery condition for a 4 year old laptop is excellent at over 90%, however a replacement can be had on Ebay for around £30 if needed and I always factor this into any second hand laptops I buy.

                                                            \n

                                                            Since I got it running I've installed Windows 7 in a Virtual Machine, in this case Virtual Box as I have a preconfigured Virtual Box HDD image that makes it less of a hassle to install as I don’t have to spend days waiting for all the updates to come through. When this is running in the background it doesn't over tax the host machine, and for Linux users it does mean you have access to that occasional bit of light weight MS software that you may need without the need to lug around 2 PC's.

                                                            \n

                                                            So did I bag a bargain, well 4 years ago on release these laptops went for £1100+ in the UK and even today they fetch £160 in good order on the likes of Ebay for a model with the specification as I originally purchased it. I would never have been in the market to spend £1000+ on a laptop now or then so the only way I can enjoy these types of machines is after they have been pre loved by someone else. Lets just say £160 is quite a bit more than I paid but with the upgrade to 256Gig mSATA drive I have a better machine for a little less than that, I personally think I bagged a bargain which will do me good service in the coming months/years.

                                                            \n

                                                            In the last episode I mentioned the confusion between then and than. I referred to the etymology of the two words, but I didn't go into detail.

                                                            \n

                                                            Reading the Online Etymology Dictionary, one interesting point in the page about than is that it was:

                                                            \n
                                                            \n

                                                            Developed from the adverb then, and not distinguished from it by spelling until c. 1700.

                                                            \n
                                                            \n

                                                            So, it would seem that the two words are related and historically were the same! However, I'd guess that it is unlikely that people using them interchangeably now are making reference to usage in the 1700's.

                                                            Let us now examine the apostrophe, which is a punctuation mark. It is used for:

                                                            • Indicating that letters have been omitted, such as in a contracted form of words. For example when the phrase they are is contracted to they're.

                                                            • When the plural of a single letter (or digit) is required such as in dot your i's and cross your t's.

                                                            \n

                                                            There are other uses but you can look at the Wikipedia article for them if you want to dig deeper. I may well revisit this topic in a later show in this series.

Phreak, phreaker, or phone phreak are names used for and by individuals who participate in phreaking.

                                                            Get Processing from processing.org. Download, extract, and launch. On Linux, just click the processing file.

                                                            Processing requires that either OpenJDK or Java to be installed.

                                                            \n

                                                            Processing requires a void setup() function, which is a function that Processing expects whenever an application is launched. If you don't have a setup function, your application still launches, but with basic Processing defaults. Try this to start with:

                                                            \n
                                                            void setup() {\n    size(480,720);\n}
                                                            \n

                                                            Click the Run button in the top left corner to launch your [very simple] application: an empty window that is 480 pixels wide and 720 pixels tall.

                                                            \n

                                                            Draw a rectangle on your canvas by invoking Processing's void draw() function:

                                                            \n
                                                            void draw() {\n    rect(10,10,80,80);\n}
                                                            \n

                                                            Click the Run button in the top left corner to launch your application.

                                                            \n

                                                            Add some colour to your rectangle:

                                                            \n
                                                            void draw() {\n    fill(8,120,90);\n    rect(10,10,80,80);\n}
                                                            \n

                                                            Click the Run button in the top left corner to launch your application.

                                                            \n

                                                            Make a simple painting app:

                                                            \n
                                                            void setup() {\n    size(480,720);\n}\n\nvoid draw() {\n    if (mousePressed) {\n        fill(20,120,90);\n        ellipse(mouseX,mouseY,25,25);\n    } else {\n        fill(random(10,120),random(10,80),random(20,200));\n    }\n}
                                                            \n

                                                            More Processing tricks: you can export your application as a standalone Java app, or as an Android .apk as long as you have the Android SDK installed.

                                                            \n

                                                            Processing's documentation is excellent. It has examples for all functions, with pictures.

                                                            \nThe Linux installer uses FlatPak, so you do need to install that.\n

                                                            \n\n

                                                            \nOnce installed, launch SparkleShare in the usual way. If you have no usual way, you can use this command:

                                                            \n\n
                                                            \n$ flatpak run org.sparkleshare.SparkleShare\n
                                                            \n\n

                                                            \nThe first screen asks for your name and email. This doesn't have to be your real name and email, but it is what SparkleShare will use when making commits on your behalf. This name and email will be visible to anyone who can see your online Git repository.\n

                                                            \n\n

                                                            \nThe next screen displays the Sync Remote Project screen. You use this screen any time you want to add another share to your sparkle.\n

                                                            \n\n\"image\n\n

                                                            \nIn this episode, I set up two projects: one brand new one using my home server as host, and one that mirrors an existing project on Gitlab.com.\n

                                                            \n\n

                                                            Adding a project from Gitlab

                                                            \n\n

                                                            \nThe first thing you must do is give SparkleShare permission to access Gitlab. To do this, click on the SparkleShare icon in your system tray > SparkleShare > Client ID and copy your ID to your clipboard.\n

                                                            \n\n\"image\n\n

                                                            \nNow go to your online Git host and add this "Client ID" to your approved SSH Keys. Where this is located depends on your Git host, but in Gitlab, it's located in the left column of the Settings screen. When your SSH Key has been added, Gitlab displays a key fingerprint (actually just a string of numbers) as confirmation.\n

                                                            \n\n

                                                            \nThe path to your remote Git repository is the part of an URL after the host. It usually starts with your username. For example, if I have a project on Gitlab located at gitlab.com/notklaatu/foo.git then the path that SparkleShare needs is notklaatu/foo.git\n

                                                            \n\n

                                                            \nClick the Add button to add the project to your local SparkleShare folder.\n

                                                            \n\n\n

                                                            Adding a project hosted on your own server

                                                            \n\n

                                                            \nThere are a lot more variables if you're hosting a Git repository on your own server. These are the things that you may need to account for:\n

                                                            \n\n
                                                              \n

                                                            • Is your local .ssh/config file setting some "invisible" defaults for when you SSH to your server? If so, you may need to modify or add an entry for SparkleShare.

                                                              • \n

                                                            • Your SparkleShare auto-generated "Client ID" is located in $HOME/.config/org.sparkleshare.SparkleShare/ssh

                                                            • Is your SparkleShare SSH key (the "Client ID" in SparkleShare lingo) in your authorized_hosts file?\n

                                                              • \n

                                                            • Does a Git repository exist on your remote server in the location you think it exists?

                                                              • \n

                                                            This is the twelfth episode of the “Learning Awk” series which is being produced by Mr. Young and myself.

                                                            \n

                                                            In this episode I want to continue with the subject I started in episode 10, an advanced-level look at arrays in Awk. This episode covers patsplit which can split a string into an array, the built-in array PROCINFO which can be used to control how awk sorts arrays, as well as asort and asorti, built-in functions for sorting arrays.

                                                            \n

                                                            In case it might be of interest I have also included a section describing a recent use I made of awk to solve a problem.

                                                            \nThis is obvious, but it tripped me up a few times after listening to the excellent Awk series by Dave and Mr. Young, so I though I'd share it here to save others the trouble.\n

                                                            \nThen your awk script won't work the way you expect.

                                                            \n\n

                                                            \nYou must provide the -f flag:\n

                                                            \n

                                                            I needed to learn how to use the software tool "quilt", so you get to listen to my podcast about an introduction to quilt.

                                                            \n

                                                            People collaborating on a project must edit the same set of source files. After one person commits some changes, then the other people must rebase their own changes on the new version of the shared files before they can push their changes.

                                                            \n

                                                            A minor fix for some old typo should not be in the same patch as a new feature; a comment correction should also be in its own patch. Essentially, two new features and some bug fixes should not all be smushed together in one patch. Each feature should be in its own patch (or patch series), and each bug fix should be in its own patch. This allows others to be able to review the proposed changes easily, and even lets them pick and choose which patches they want to apply. It becomes a chore to manage all these patches. That's where quilt comes in.

                                                            \n

                                                            Sadly, I hadn't learned quilt till this weekend ... well one way to ensure I learn it fairly well is to write a HPR episode about it! Here goes.

                                                            \n

                                                            I have written this episode to be understandable by anyone - you don't have to be a coder. You could use this tool to keep track of any plain-text files - recipes, todo lists, html, hpr show notes, poetry, what-have-you.

                                                            \n

                                                            Introduction

                                                            \n

                                                            First let's describe what a patch is. No, first let's describe what source code looks like. Source code is a plain text file full of computer instructions. It is a plain text file, as opposed to a word processing file. Plain text files do not have any formatting codes or styles in them (such as which font should be used, or what colour, and so on). They just contain the characters that make up words of the content.

                                                            \n

                                                            A key feature of these source code files is that a new section of the file starts on a new line. The source code is almost never "reflowed" like prose might be. It is sort of like poetry - the more formal poetry, not prose poetry. There are a lot of really small sections in source code files (called "statements" and "expressions"). Most of these sections fit on one line. This is useful for the tools we're going to discuss because when one line changes it does not affect the following lines, as it might when text is reflowed after a change.

                                                            \n

                                                            People have been coding with plain text files in various languages for decades. Thus a large set of tooling has grown around this format. One of those tools is called "diff" and another one is called "patch".

                                                            \n

                                                            Diff is a way to compare two text files. Typically it would be used to compare the "before" and "after" of a source code file undergoing changes. So you could find out what was done to the source code file by running diff on the before and after versions of that file.

                                                            \n

                                                            A diff file is a series of excerpts from the original and changed files. There are various kinds of diffs. Some of them show only the changed lines. Some of them show a few lines before and a few lines after in addition to the changed lines themselves. That second kind is called a "context diff" and helps the automated machinery (and humans too) find the correct part of the file to which the change must be applied.

                                                            \n

                                                            By default there are 3 lines of context before and after the changed lines.

                                                            \n

                                                            The changed part is represented by including the old AND new line. In order to distinguish which lines are old and which are the replacements, all the lines (context lines, removed lines and added lines) are shifted over to the right by one character. The context lines start with a space in the extra left-most character, the original removed lines have a minus sign in the left-most character and the new added lines have a plus sign.

                                                            \n

                                                            Thus if any character on a line in the source file has changed, been added or removed, then the whole line will be replaced with a new line in the new file. The diff will show both the removed line and the new one.

                                                            \n

                                                            The patch utility takes the "diff" output and applies it to the original file to produce the later version of that file. You can apply it in reverse mode to the later version to get the original version. So patch is also a really useful program, and these two tools, diff and patch, are the basis of most of the version control systems out there. It is the existence of these text-based diff and patch tools that makes revision control systems work really well on plain-text files that are naturally structured in a line-by-line format.

                                                            \n

                                                            A note about terminology: the diff program produces a diff. This diff is also called a patch. The patch program takes the diff (aka patch) and applies it to the original file to produce the changed file.

                                                            \n

                                                            So if you have a timeline of adding a few features and making a few fixes on a code-base, it can be fully described by the original file plus a set of patches that had been produced with diff. You can get the final source code by taking the original file, applying the patches one by one, and voila, the final version of the file has been recreated.

                                                            \n

                                                            Now we know enough to give a concise description of quilt:

                                                            \n

                                                            Quilt lets you work with patches, creating them, applying them, un-applying them, and moving some things from one patch to another with a minimum of effort.

                                                            How to use quilt

                                                            \n

                                                            Now a tutorial on how to get started using quilt.

                                                            \n

                                                            This tutorial will start with a buggy program, create a few bad patches, and fix them up into good patches. I make no claims as to the quality of the final code though. The reason for starting with bad code and patches is to illustrate how to use quilt.

                                                            \n

                                                            Starting to use quilt on a project

                                                            \n

                                                            To start using quilt, create a directory called "patches" at the top of your code or just above.

                                                            \n
                                                            $ mkdir patches
                                                            \n

                                                            If you don't do this, quilt will create it for you. However, first it will look for a directory called "patches" in the current working directory, its parent, and all the way up ... if it finds one, it will use it. If not, it will create one in the current directory.

                                                            \n

                                                            So, to keep it from finding some unrelated directory with the name "patches", just create a patches directory yourself in the right place.

                                                            \n

                                                            Quilt first patch, including a new file!

                                                            \n

                                                            You must tell quilt before you make any changes to your source code. Then it can store the original versions of the files that will change, so it can produce the diffs that will become that patch once you change the files.

                                                            \n

                                                            Create a directory called example, and create a file in it like this, called hello.c (don't fix the errors):

                                                            \n
                                                            #include "stdio.h"\n\nint main (int argc, char *argv[], char *env[])\n{\n    print ("Hello, world!n")\n    return 0;\n}
                                                            \n

                                                            Now create a new patch - that is, give it a name - before you change any code. This will create (or find) a couple of directories, "patches" and ".pc", and populate them with some files to start.

                                                            \n
                                                            $ quilt new fix-typo
                                                            \n

                                                            And now you can fix the typo and generate the patch. First start by telling quilt that you want hello.c to be in the patch. Quilt saves a copy of it aside for comparing with the later versions:

                                                            \n
                                                            $ quilt add hello.c
                                                            \n

                                                            You can get quilt to tell you what files it knows about:

                                                            \n
                                                            $ quilt files
                                                            \n

                                                            Edit the file - add a semicolon at the end of the print line, and change the double-quotes on the #include line to angle brackets:

                                                            \n
                                                            #include <stdio.h>\nprint ("Hello, world!n");
                                                            \n

                                                            Save the file and exit the editor. Next generate the patch:

                                                            \n
                                                            $ quilt refresh
                                                            \n

                                                            The oddly named "refresh" command creates the patch itself. It is called "refresh" because it can also be used to update the patch.

                                                            \n

                                                            Now you can see the current set of patches by giving the command:

                                                            \n
                                                            $ quilt series
                                                            \n

                                                            The single patch is called fix-typo, and its name in the list is coloured brownish. That is because it is the "current" patch, and it is the one that will be updated if you "quilt refresh" again with more changes.

                                                            \n

                                                            One thing I did not find in the quilt documentation is how to add a new file. When adding a new file, there is no existing file that you can name in the quilt add command. Of course, the very first patch I wanted to manage with quilt, I had introduced a new file. It turns out that the quilt edit command can be used to add a file to the patch, even if the file does not yet exist:

                                                            \n
                                                            $ quilt edit header.h
                                                            \n

                                                            Add content to header.h (see below) using the plain-text editor that quilt has started up for you. Save the file.

                                                            \n
                                                            #ifndef HEADER_HH__\n#define HEADER_HH__\n\n#define NAME "bjb"\n\n#endif
                                                            \n

                                                            Regenerate the patch with the new changes:

                                                            \n
                                                            $ quilt refresh
                                                            \n

                                                            Now you can list the patch series again with quilt series. So far there is one patch. You can see what the patch consists of with the

                                                            \n
                                                            $ quilt diff
                                                            \n

                                                            command.

                                                            \n
                                                            $ quilt diff\nIndex: hello/hello.c\n===================================================================\n--- hello.orig/hello.c\n+++ hello/hello.c\n@@ -1,8 +1,8 @@\n-#include "stdio.h"\n+#include <stdio.h>\n\n int main (int argc, char *argv[], *env[])\n {\n-    print ("Hello, world!n")\n+    print ("Hello, world!n");\n     return 0;\n }\n\nIndex: hello/header.h\n===================================================================\n--- /dev/null\n+++ hello/header.h\n@@ -0,0 +1,7 @@\n+#ifndef HEADER_HH__\n+#define HEADER_HH__\n+\n+#define NAME "bjb\n+\n+#endif\n+\n$

                                                            Quilt second patch

                                                            \n

                                                            Now it is time to make a second patch. First we tell quilt we are moving to a new patch:

                                                            \n
                                                            $ quilt new prototype\n$ quilt edit header.h
                                                            \n

                                                            Edit this file again - add a function prototype.

                                                            \n
                                                            int do_output(const char *name);
                                                            \n

                                                            Create the patch and look at the list of patches:

                                                            \n
                                                            $ quilt refresh\n$ quilt series
                                                            \n

                                                            Now when we give the quilt series command, we see two patches. The first one is green, meaning it has been applied, and the second one is brown, meaning this is the one that quilt refresh will change if you call it.

                                                            \n

                                                            Again you can see what latest diff looks like by giving the quilt diff command.

                                                            \n
                                                            $ quilt diff
                                                            \n

                                                            Now let's unapply the latest diff:

                                                            \n
                                                            $ quilt pop\n$ quilt series
                                                            \n

                                                            We see that the list of patches has the same patches in it, but now the second patch is white (meaning unapplied) and the first patch is brown (meaning it is the one that would change if we edited a file and typed quilt refresh.

                                                            \n
                                                            $ quilt files
                                                            \n

                                                            That first patch has two files in it, hello.c and header.h.

                                                            \n

                                                            Now unapply the first diff:

                                                            \n
                                                            $ quilt pop\n$ quilt series
                                                            \n

                                                            Both patches are listed, and both are shown as white.

                                                            \n

                                                            We can see what files quilt knows about before any patches are applied:

                                                            \n
                                                            $ quilt files
                                                            \n

                                                            No files.

                                                            \n

                                                            Apply all the patches at once:

                                                            \n
                                                            $ quilt push -a\n$ quilt series
                                                            \n

                                                            And look at what files quilt knows about:

                                                            \n
                                                            $ quilt files
                                                            \n

                                                            Now quilt reports on only one file, while in the first patch it knew about two files. You must be careful to "add" each file to each patch, or it will not put the changes in those files into the patch. Luckily, quilt edit will put the files in the patch for you, so if you always start your editor with quilt edit fname, then you will have your changed files added to your patches without having to take any other action. But, if you are adding an existing file to the patch, you can add it without having to open your editor with the quilt add command:

                                                            \n
                                                            $ quilt add fname
                                                            \n

                                                            In order to avoid forgetting to add a file in a patch as I was editing, I just added all the files in the directory each time I created a new patch, whether I edited them or not.

                                                            \n

                                                            Split a patch in two parts

                                                            \n

                                                            We are going to split the first patch in two parts. We had fixed a typo and added a new file in one patch. They should be two separate patches.

                                                            \n

                                                            First make the first patch current:

                                                            \n
                                                            $ quilt pop
                                                            \n

                                                            Then make a copy of that patch:

                                                            \n
                                                            $ quilt fork
                                                            \n

                                                            This makes a copy of the first patch called fix-typo-2. But, it removes the first patch fix-typo and puts fix-typo-2 in the series. We need to put the first patch back, and then edit each of the two fix-typo patches so each one contains one part of the original patch.

                                                            \n
                                                            # edit patches/series file and put the first patch back\n# The file should contain:\n\nfix-typo\nfix-typo-2\nprototype
                                                            \n

                                                            Now edit the first patch using a plain-text editor. It is in patches/fix-typo. Remove the part about the new file, header.h. It should now look like:

                                                            \n
                                                            Index: hello/hello.c\n===================================================================\n--- hello.orig/hello.c\n+++ hello/hello.c\n@@ -1,4 +1,4 @@\n-#include "stdio.h"\n+#include <stdio.h>\n\n int main (int argc, char *argv[], *env[])\n {
                                                            \n

                                                            Save this file. Now edit the second patch patches/fix-typo-2 using a plain-text editor. Remove the part about the file hello.c. It should now look like:

                                                            \n
                                                            Index: hello/header.h\n===================================================================\n--- /dev/null\n+++ hello/header.h\n@@ -0,0 +1,7 @@\n+#ifndef HEADER_HH__\n+#define HEADER_HH__\n+\n+#define NAME "bjb\n+\n+#endif\n+
                                                            \n

                                                            If you give a quilt series command now, you will see that fix-typo-2 is the current patch and quilt thinks fix-typo has been applied.

                                                            \n

                                                            We have to fix up quilts idea of reality.

                                                            \n

                                                            Pop the current patch. Things have changed under quilts feet so we have to force this with the -f option:

                                                            \n
                                                            $ quilt pop -f
                                                            \n

                                                            Now, because quilt thought the original state of fix-typo-2 is the unchanged file, quilt shows the series as being completely un-applied.

                                                            \n
                                                            $ quilt series\npatches/fix-typo\npatches/fix-typo-2\npatches/prototype
                                                            \n

                                                            Now we can push the patches:

                                                            \n
                                                            $ quilt push -a
                                                            \n

                                                            Rename a patch

                                                            \n

                                                            Here we rename a patch from fix-typo-2 to add-header. The quilt rename command acts on the current patch, so make fix-typo-2 current first:

                                                            \n
                                                            $ quilt pop fix-typo-2\n$ quilt rename add-header\n$ quilt series\n$ quilt push -a
                                                            \n

                                                            Reorder the patch series

                                                            \n

                                                            We will make a new patch, then move it earlier in the series:

                                                            \n

                                                            First make the new patch:

                                                            \n
                                                            $ quilt new printf\n$ quilt edit hello.c
                                                            \n

                                                            And change the print statement to:

                                                            \n
                                                            printf("Hello, world!n");
                                                            \n

                                                            Save the patch:

                                                            \n
                                                            $ quilt refresh
                                                            \n

                                                            Now to demonstrate the reordering.

                                                            \n

                                                            Unapply all the patches, edit the patches series file patches/series so the patches are in the order you like, and then re-apply the patches. If you are lucky, they will re-apply with no conflicts.

                                                            \n
                                                            $ quilt pop -a\n$ vi patches/series\n# move "printf" between fix-typo and add-header.\n# now all the bug-fixes are at the beginning of the series\n$ quilt push -a
                                                            \n

                                                            Merge two patches into one

                                                            \n

                                                            Make another new patch:

                                                            \n
                                                            $ quilt new output-function\n$ quilt edit hello.c
                                                            \n

                                                            Change the c file to this:

                                                            \n

                                                            \n

                                                            Now, to merge two patches into one:

                                                            \n
                                                            $ quilt pop prototype\n$ quilt fold < patches/output-function
                                                            \n

                                                            We have merged the prototype and output-function patches, because they describe a related change.

                                                            \n

                                                            Save the patch.

                                                            \n
                                                            $ quilt refresh
                                                            \n

                                                            Throw away a patch

                                                            \n

                                                            Now we no longer need the last patch, output-function, as it has been included into the prototype patch. But we might want to rename the prototype patch.

                                                            \n
                                                            $ quilt delete output-function\n# we have to clean up a bit for quilt or the rename won't work\n$ rm patches/output-function\n$ quilt rename output-function
                                                            \n

                                                            Deleting will not work on a patch that has been applied before the current patch.

                                                            \n

                                                            You are ready to contribute your patches ... go forth and code.

                                                            We have seen that quilt can help you manage your contributions to any project that is written in plain-text files. It can generate patch files (usually needed for contributions to open source projects) and can help you manage and update them as the tip of the development branch moves forward with other peoples' contributions.

                                                            \n

                                                            To use quilt successfully, you need to remember to add files to each patch with quilt add/or quilt edit before editing, and to generate the patch with quilt refresh once all the editing of each patch is done. The rest is easy.

                                                            \n

                                                            1. Teach as much as possible in the new language, focusing on vocabulary.
                                                              2. \n
                                                            2. Rather than starting with baby books, which might not be a bad idea, try to use a similar approach but assume the learners know a bit about how the world works.
                                                              3. \n
                                                            3. The goal is to get to about age 5-6 level in vocabulary so the learner can then switch to language books in the new language which already exist.
                                                              4. \n

                                                            Yes, this talk is about running your own mainframe on your own hardware. Mainframes are old, yes, but they are still very much alive. New hardware is still being developed and there are a lot of fresh jobs in this area too. A lot of mainframes run COBOL workloads. COBOL is far from a dead language. It processes an estimated 85% of all business transactions, and 5 billion lines of new COBOL code are written every year. In this session the speaker will help you in take your first steps towards running your own mainframe. If you like then after this session you can continue to build your knowledge of mainframe systems using the links provided during the talk. Come on in and learn the basics of a completely different computer system! And it will take you less than an hour to do that!

It visualizes the directory tree in two dimensions: the directory hierarchy on one, lists of files on the other, with a preview to the right so you know where you’ll be going.

Located at $HOME/.config/ranger/scope.sh, scope is the feature that allows for file preview from inside the console. Text files are highlighted based on their file extension, for non-text files, different converters can be used to coerce the file into a text representation. Some items are available out of the box, but the configuration is written in such a way that any text can be presented in the preview screen.

                                                            It seems to me that it would be worthwhile looking at how Bash can be used to make decisions, such as how many times a loop should cycle (looping constructs) or to choose between multiple choices (conditional constructs). Of course we need to look at some of the expressions used in conjunction with the commands that do these tasks – the tests themselves – and we’ll do this in this episode.

                                                            This is a complex area which I had some trouble with when I first started using Bash, and there is a lot to say about it all. I have prepared a group of HPR shows about this subject, in order to do it justice, and this is the first of the group.

                                                            Below I’ll cover some of the items I missed or didn’t understand when I recorded my off the cuff episode. If I miss something you may find it in the user manual link above.

                                                            \n

                                                            Full and Semi break-in mode is used when operating in CW mode (Morse Code). In full break-in mode the radio jumps back into receive the moment the mores key is released this way you can hear if the station is trying to contact in-between each press of the key. This is very demanding on the radio as it must switch very quickly back into receive mode it can also be distracting for the operator hearing hissing noise between each dot and dash. Semi break-in mode is a bit like using VOX mode in speech the radio goes silent between each dot and dash but will return to receive after the mores key is released for a predetermined time interval.

                                                            \n

                                                            The digital display used on the main display of the TS940S is apparently a Vacuum Fluorescent Display not the more usual LED of the time.

                                                            \n

                                                            The TS 940S was manufactured around 1986, so unbelievably that means my wonderful radio that to me looks fairly modern is around 30 years Old! I believe this HF radio was top of the line for Kenwood back then.

                                                            \n

                                                            The Auto and thru button is used to connect the auto tuner in line with the antenna. When AUTO is selected the radio is connected to the Auto internal tuner and then to the antenna. In THRU the radio bypasses the auto tuner and connects the radio directly to the antenna.

                                                            \n

                                                            \n

                                                            During SSB operation it is desirable to increase the relative “talk power” of the transceiver by using speech processor circuitry. The speech processor control is set by using the in and out rotary control. The in control level is set by putting the meter into Comp and adjusting the in control to no more than 10 dB of compression. The out control level is set by putting the meter into ALC and adjusting the out control to ensure the meter stays within the ALC section of the meter.

In this episode we’ll look at the constructs that use these tests: looping constructs, conditional constructs and lists of commands.

                                                            National Podcast Post Month (or NaPodPoMo) is a challenge in a similar vein to National Novel Writing Month (or NaNoWriMo) in which participants are challenged to produce and publish a piece of audio as a podcast, every day for the month of November.

                                                            Bad podcast audio

                                                            Audio quality is as important as the content that's being presented. Bad audio is going to be what causes new podcasters the most damage in subscriber numbers. An example of good audio is the true crime podcast, One Eye Open, which Dave started listening to a couple of weeks ago. He also picked up a couple of other true crime podcasts as a result of listening to One Eye Open where the audio quality is so bad, that they can't be heard!

                                                            Loudness is a measurement of how loud something is perceived to be. Levelling is a process of ensuring that individual tracks in a podcasts are an an equivalent level, but also the podcast overall is at an equivalent level to other podcasts that have been levelled the same way.

You just need something to record into (e.g. a mobile phone or portable recorder) and somewhere to host it. You can host on your own website or on one of a number of free services, like Anchor, AudioBoom, or indeed Hacker Public Radio!

Now we want to start examining the expressions that can be used in these tests, and how to combine them. We will also start looking at string comparisons in extended tests.

                                                            Well Ken made another call for shows and as my recent interview series has come to an end by the time you listen to this here is a short review of a USB3 2.5inch HDD/SSD caddy I got from E-bay a few weeks ago.

                                                            \n

                                                            As many of you who have listened to my previous ramblings know I frequent a local Computer auction and recently they have had some cheap 128Gig SSD’s for sale and I managed to pick several up at a good price. After using some to upgrade some desktop PC’s to SSD I had a couple of these spare and as I have USB3 on my main laptop thought it would be good to be able to use one or two of these as portable storage or even for boot drives to test out odd Linux distro or 2.

                                                            \n

                                                            So I purchased a caddy off that font of all things techie E-bay for £5.50, link here:
                                                            \nhttps://www.ebay.co.uk/itm/USB-3-0-to-SATA-Hard-Drive-Enclosure-Caddy-Case-For-2-5-Inch-HDD-SSD-External/282930148654?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2648

                                                            \n

                                                            So after it arrived I plugged in one of the drives and tested it out. The first thing to notice is that SSD’s being 7mm in depth flop about a bit in the case but this is easily resolved by a bit of card under the drive to help it fit snug in the case and it does mean that the case will support the larger 9mm 2.5inch spinners if needed. I’ve not tested a larger older spinner but I suspect they will not fit as 9mm ones are very snug in the case.

                                                            \n

                                                            Anyway the drive was detected by the PC/Laptop and works flawlessly and as it is so quick to swap drives in the caddy means I can carry large data files and my music and video library when on the move with the advantage that it is less likely to be damaged if accidentally dropped or knocked off a surface, which is quite likely with a portable spinner HDD.

                                                            \n

                                                            I am very happy with this purchase and it has already become a regular part of my travelling tool kit/laptop bag.

                                                            My git workflow

                                                            \n

                                                            In this episode of HPR I present the workflow I use to contribute to opensource projects using git. I have no idea if this workflow is something that is commonly used, but it is working for me, so I thought I’d share it with the HPR community.

                                                            \n

                                                            The first thing I do is fork the project I want to contribute to. This is done on github most of the time, although this workflow can work on gitlab, bitbucket, or even some self hosted git platform.

                                                            \n

                                                            Once the project is forked, I clone it on my machine :

                                                            \n
                                                            $ git clone git://server/path/to/myproject.git
                                                            \n

                                                            Git automatically names my remote project origin.

                                                            \n

                                                            Then I add a reference to the original project :

                                                            \n
                                                            $ git remote add upstream https://server/path/to/originalproject.git
                                                            \n

                                                            Now my local repository references my fork under the name origin and the original project under the name upstream.

                                                            \n

                                                            In this workflow, I never work on the master branch. So, when I need to fix a bug for example, I create a new branch :

                                                            \n
                                                            $ git checkout -b bugfix
                                                            \n

                                                            I can then make changes, test my code, make sure everything is ok, stage and commit my changes :

                                                            \n
                                                            $ git add .\n$ git commit -m "commit message"
                                                            \n

                                                            Now I need to push this local branch to my repository on github :

                                                            \n
                                                            $ git push -u origin bugfix
                                                            \n

                                                            Since I forked the original project, github knows that origin and upstream are linked. If there are no conflicts, github will show me a big green button to create a pull request. Once the pull request is created, I just have to wait for the maintainer to merge it in upstream’s master branch. Then, I need to sync both my local copy and my fork on github with the original project. In order to do that, on my local copy, I checkout my master branch, fetch upstream’s changes, and merge them :

                                                            \n
                                                            $ git checkout master\n$ git fetch upstream\n$ git merge upstream/master
                                                            \n

                                                            Now my local master branch is ahead of origin’s master branch, so I push those changes to github :

                                                            \n
                                                            $ git push
                                                            \n

                                                            I don’t need the bugfix branches (the local one and the github one), so I can delete those :

                                                            \n
                                                            $ git branch -d bugfix\n$ git push origin -d bugfix
                                                            \n

                                                            And now, my local repository is even with both origin and upstream, and I can start again.

                                                            \n

                                                            To summarize, here’s the complete workflow :

                                                            \n
                                                            $ git checkout -b myawesomefeature\n$ git add .\n$ git commit -m "Awesome commit message"\n$ git push -u origin myawesomefeature
                                                            \n

                                                            Create a pull request, wait for the maintainer to merge it.

                                                            A typical manual Antenna Tuner has two rotatable knobs both interact with each other. The Tuner is used to match a badly tuned antenna to your transmitter. The Tuner is placed in-between the transmitter and antenna. To use it you typically hold down the transmit key while looking at the VSWR meter and rotating one knob at a time in turn repeating this operation until the minimum VSWR is achieved.

We looked at conditional expressions and all of the operators Bash provides to do this. We concentrated particularly on string comparisons which use glob and extended glob patterns.

To install Porteus to a thumbdrive, you need a thumbdrive with an EXT4 partition. You can try other filesystems and partition schemes, but EXT4 definitely works well.

                                                            \nAlternately, you can use Porteus from a virtual machine and install to a thumbdrive, as long as your virtualisation software redirects USB. I have used virt-manager running on Fedora successfully for this.\n

                                                            \n\n

                                                            The other alternative, of course, is to run Porteus off of an optical disc. That means your system is unwritable, so nothing you do is persistent across reboots, but you can save your work to a thumbdrive. I've worked with Slax this way before, and it's quite manageable.

                                                            \n\n

                                                            Boot

                                                            \n\n

                                                            \nBooting to Porteus depends a lot on the firmware of the computer you're booting. Almost every Linux distro in existence has accurate docs on the changes you may or may not need to make to your BIOS or [U]EFI in order to boot to Linux, so you can find more detail on this if you need. Here's some text I borrowed from Linux Mint:\n

                                                            \n\n

                                                            Insert your USB stick (or DVD) into the computer.

                                                            \n

                                                            Restart the computer.

                                                            \n

                                                            Before your computer boots your current operating system (Windows, Mac, Linux) you should see your BIOS or UEFI loading screen. Check the screen or your computer’s documentation to know which key to press and instruct your computer to boot on USB (or DVD). Most BIOS or UEFI have a special key you can press to select the boot device and all of them have a special key to enter a configuration screen (from which you can define the boot order). Depending on the firmware, these special keys can be Escape, F1, F2, F8, F10, F11, F12, or Delete. That information is usually briefly displayed on screen during the boot sequence.\n

                                                            \n

                                                            \nOn Macs, keep your finger pressed on the Alt or Option key after hearing the boot sound.\n

                                                            \n\n

                                                            Boot modes

                                                            \n\n

                                                            Porteus can boot to its default persistent modes: graphical or text. Both of these modes auto load any Porteus modules you've installed and also read any changes you made since the previous boot.\n

                                                            \n

                                                            It can also boot to ephemeral modes: Copy to RAM and Always Fresh. These modes act as if you've never booted into Porteus before, loading a completely fresh version of the file system. They also do not load Porteus modules automatically.

                                                            \n\n

                                                            Installing software

                                                            \n\n

                                                            Porteus modules are Slackware packages converted to .xzm files, a highly-compressed SquashFS filesystem. When a Porteus module is activated, the application and other files contained in the module appear in your environment. You can think of it as a layered filesystem.

                                                            \n\n

                                                            \nTo install software, you must sync up your package manager with upstream repositories:

                                                            \n\n
                                                            $ sudo usm -u all\n
                                                            \n\n

                                                            \nOnce everything is updated, you can search for packages using the -k (for keyword) option:

                                                            \n\n
                                                            $ sudo usm -k foo\n
                                                            \n\n

                                                            \nAnd then install it:

                                                            \n\n
                                                            $ sudo usm -g foo\n
                                                            \n\n

                                                            \nYou are prompted to either install or download the module. If you install it, then it becomes part of the filesystem. However, since changes to the filesystem are NOT read by the Copy to RAM or Always Fresh modes, this is probably not what you want. Instead, download the module so that you can have Porteus load it dynamically regardless of what mode you're running.

                                                            \n\n

                                                            \nModules are downloaded, by default, to /tmp/usm/ and then converted from their native format of .t?z to .xzm files. You can copy the .xzm files to an external device if you're running off of optical media, or into a persistent area on the thumbdrive running Porteus. Modules can be made permanently available in the /mnt/sdx1/porteus/modules or /mnt/sdx1/porteus/optianal directories.\n

                                                            \n\n

                                                            Modules in the ../modules path are loaded at boot in the Graphical and Text modes, and are available to load manually in the Copy to RAM and Always Fresh modes.

                                                            Modules in the ../optional path are never auto loaded.

                                                            \n\n

                                                            Modules can be activated or deactivated with this command:

                                                            \n\n
                                                            $ sudo activate foo\n
                                                            \n\n

                                                            Miscellany

                                                            \n\n

                                                            Flatpak works on Porteus, too. I have found this to be convenient for applications like GIMP and Inkscape and Kdenlive and many others that are complex enough to warrant special attention.\n

                                                            \n\n

                                                            \nFlatpak does require the glib-networking package. You will not be warned about this, because all upstream Slackware repositories assume a full install of Slackware (and glib-networking is included on Slackware, but not on Porteus). Once you install glib-networking, you can use flatpak as described, for instance, on the GIMP downloads page.\n

                                                            \n\n

                                                            \nOver-customizing the \"hard-coded\" parts of Porteus is unwise. For instance, keep the default user (guest), don't try to change the UID (I tried and failed), and so on. Treat the system, more or less, as if though you were a guest on someone else's multi-user system. Install and customise stuff locally and through modules when possible. That's what Porteus expects, and things can break if you try to treat it too much like a traditional Linux system.\n

                                                            I thought I was done with this topic, but got to thinking about bringing a game to life it occurred to me it was a lot of work. So I thought about it some more and hit upon the idea of an RPG probably mostly played online where a key point of the game is that the players needn’t know the same language.

                                                            \n

                                                            At first this seems like an odd thing for an RPG because the talking to each other is sort of a requirement. By now you’ve guessed that what I mean is that the game could be designed so that it assumes the players will have limited ability to communicate. And that drives how the game progresses.

                                                            \n

                                                            I see two kinds of approaches. One is that players sort of team up by the their native languages so you might have people knowing different native languages working in smaller teams while the whole game has the goal of everyone learning the new language.

                                                            \n

                                                            The other is that everyone could know a different native language and many or may nor cooperate with others but the goal of the game is everyone learning the same new language.

The TS-940S accomplishes this without shifting the actual transmitter or receiver frequency, by shifting the 100kHz IF frequency, just prior to Product detection.

With this control, it is possible to accentuate the desired signal by providing additional rejection of noise and interfering signals whose pitch (tone) falls outside the audio passband. Turn the AF TUNE switch ON and adjust the AF TUNE control to peak the desired signal.

We looked at conditional expressions and all of the operators Bash provides to do this. We concentrated particularly on string comparisons which use glob and extended glob patterns then we devoted an episode to Bash regular expressions.

Adjusting the RF GAIN so that the S-meter reading increases to a point just lower than speech peaks. This also reduces noise during reception. For normal operation, this control should be turned fully clockwise for maximum sensitivity.

Episodes 9-13 covered Making Decisions in Bash and in these episodes we looked at while and until loops, but not for loops. This episode is making good this deficiency, and is also looking at break and continue which are very useful when using loops.

                                                            Stack is a build tool for Haskell with focus on reproducible build plans, multi-package projects, and a consistent, easy-to-learn interface. With stack, one can create new project: stack new my-project yesod-sqlite (more in the quick start guide: https://www.yesodweb.com/page/quickstart)

                                                            \n\n

                                                            models is used to define shape of the data and Yesod uses it to generate datatypes and database for you. For example, to define a Star that has name, spectral type, luminosity class and link to StarSystem, one can write:

                                                            \n\n
                                                            \nStar json\n    name Text\n    starSystemId StarSystemId\n    spectralType SpectralType\n    luminosityClass LuminosityClass\n
                                                            \n\n

                                                            Custom types, like LuminosityClass, need mapping between datatype and database. In simple cases like this, Yesod can do that:\n\n

                                                            \ndata LuminosityClass = Iap | Ia | Iab | Ib | II | III | IV | V | VI | VII\n    deriving (Show, Read, Eq)\nderivePersistField \"LuminosityClass\"\n
                                                            \n\n

                                                            The \"derivePersistField\" part is template haskell call that will generate mapping needed.

                                                            \n\n

                                                            For those who don’t know on New Years Eve 2018-12-31 at 10:00 am UTC (5:00 am EST) we will have a recording going on the HPR Mumble server (at ch1.teamspeak.cc on port 64747) for anyone to come on say “Happy New Year” and talk about what ever they want.

                                                            \n

                                                            We will leave the recording going until 2019-01-01 12:00 am UTC (7:00 am EST) or until the conversation stops.

                                                            \n

                                                            For those who have never used Mumble before, we have a guide over at linuxlugcast.com in our how to section explaining how to setup the desktop Mumble client, but Mumble isn’t only available for the desktop. It is also available for Android and IOS.

                                                            xsv is a command line program for indexing, slicing, analyzing, splitting and joining CSV files. Commands should be simple, fast and composable:

                                                            \n
                                                              \n
                                                            1. Simple tasks should be easy.
                                                              2. \n
                                                            2. Performance trade offs should be exposed in the CLI interface.
                                                              3. \n
                                                            3. Composition should not come at the expense of performance.
                                                              4. \n

In the last episode we looked at the 'for' loop, and prior to that we looked at 'while' and 'until' loops. In this one I want to look at some of the loop-related issues that can trip up the unwary user.

                                                            Loops in Bash are extremely useful, and they are not at all difficult to use in their basic forms. However, there are some perhaps less than obvious issues that can result in unexpected behaviour.

Well worth the 32 USD plus shipping in my opinion. Claims 10 hours of game play and that seems about right so far for me.

Other systems of similar or earlier vintages have emulators that you have to install separately and boot into to run. I don’t think it will emulate newer systems. No Gameboy Advance emulator and I don’t see a Mame emulator. However, I do think this ‘might’ support Mame for some of the early arcade games like Asteroids and Space Invaders.

I normally talk about my own stuff but while it is related to what I have been doing lately this is a response to Al’s interview with Dave in Episode 2658 and how to setup Audacity to record and edit audio for best sound quality when podcasting.

The information that Dave provided during the show was invaluable in helping me in this task, I also have to give a shout out to Rob the previous host who also spent an hour and a half giving a tutorial on his post production work flow, but the additional information given by Dave in this show was also a big help.

Ah well that’s a problem for another day.

                                                            Data from database need to be transformed before working on it. Usually it's 1:1 mapping, but sometimes it makes sense to enrich it (turning IDs into names for example). For this we use ReportTransform type class:

                                                            \n\n

                                                            \n\n

                                                            To easily combine bunch of collated reports together, we define instances\n of semigroup and monoid for collated report data.\n Semigroup defines an associative binary operation (<>) and monoid defines a zero or empty item (mempty). My explanation about Monoid and Semigroup were a bit rambling, so maybe have a look at https://wiki.haskell.org/Monoid which explains it in detail.

                                                            \n\n
                                                            \ninstance Semigroup CollatedPlanetReport where\n    (<>) a b = CollatedPlanetReport (cprPlanetId a)\n\t\t\t\t    (cprSystemId a)\n\t\t\t\t    (cprOwnerId a <|> cprOwnerId b)\n\t\t\t\t    (cprName a <|> cprName b)\n\t\t\t\t    (cprPosition a <|> cprPosition b)\n\t\t\t\t    (cprGravity a <|> cprGravity b)\n\t\t\t\t    (max (cprDate a) (cprDate b))\n\ninstance Monoid CollatedPlanetReport where\n    mempty = CollatedPlanetReport (toSqlKey 0) (toSqlKey 0) Nothing Nothing Nothing Nothing 0\n
                                                            \n\n

                                                            In some cases there might be a list of collated reports that are about different entities of same type (several reports for every planet in solar system). For those cases, we need a way to tell what reports belong together:

                                                            \n\n
                                                            \n-- | Class to indicate if two reports are about same entity\nclass Grouped a where\n    sameGroup :: a -> a -> Bool\n\ninstance Grouped PlanetReport where\n    sameGroup a b =\n\tplanetReportPlanetId a == planetReportPlanetId b\n
                                                            \n\n

                                                            After this, processing a list of reports for same entity is short amount of very general code:

                                                            \n\n
                                                            \n-- | Combine list of reports and form a single collated report\n--   Resulting report will have facts from the possibly partially empty reports\n--   If a fact is not present for a given field, Nothing is left there\ncollateReport :: (Monoid a, ReportTransform b a) => [b] -> a\ncollateReport reports = mconcat (map fromReport reports)\n
                                                            \n\n

                                                            For reports of multiple entities is bit more complex, as they need to be sorted first, but the code is similarly general:

                                                            \n\n
                                                            \n-- | Combine list of reports and form a list of collated reports\n--   Each reported entity is given their own report\ncollateReports :: (Grouped b, Monoid a, ReportTransform b a) => [b] -> [a]\ncollateReports [] = []\ncollateReports s@(x:_) = collateReport itemsOfKind : collateReports restOfItems\n    where split = span (sameGroup x) s\n\t  itemsOfKind = fst split\n\t  restOfItems = snd split\n
                                                            \n\n

                                                            Final step is to either render reports as HTML or send them as JSON back to client. For JSON case we need one more type class instance (ToJSON) that can be automatically generated. After that handler function can be defined. After authenticating the user and checking that they are member of a faction, reports of specific planet (defined by its primary key) are retrieved from database, collated, turned into JSON and sent back to client:

                                                            \n\n
                                                            \n$(deriveJSON defaultOptions {fieldLabelModifier = drop 3} ''CollatedPlanetReport)\n\ngetApiPlanetR :: Key Planet -> Handler Value\ngetApiPlanetR planetId = do\n    (_, _, fId) <- apiRequireFaction\n    loadedPlanetReports <- runDB $ selectList [ PlanetReportPlanetId ==. planetId\n\t\t\t\t\t      , PlanetReportFactionId ==. fId ] [ Asc PlanetReportDate ]\n    let planetReport = collateReport $ map entityVal loadedPlanetReports :: CollatedPlanetReport\n    return $ toJSON planetReport\n
                                                            \n\n

                                                            1. Introduction

                                                            \n

                                                            Hello and welcome to Hacker Public Radio, I’m Edward Miro and I’ve been a fan of HPR for a while now and really love its collaborative and random nature. It’s always been important for me to support the hacking community. I always take any opportunity to give back to this community who have given me so much throughout the years. I’ve also always subscribed to the idea that the best way to learn something is by teaching and I hope to do a good job for all you listeners. This talk is on mystical art of steganalysis which is the process of identifying the presence of and decrypting (hopefully) steganography.

                                                            \n

                                                            2. What is steganography?

                                                            \n

                                                            I’m into hacking, but I’m not a professional hacker. Usually I call myself a hobbyist. I like CTFs, crypto challenges, lots of stuff from Vulnhub or OverTheWire, things like that. I’ll provide some links in the end if anyone is interested, but for those who aren’t familiar a CTF, or Capture The Flag, it’s a kind of game that helps you get better at hacking. These days there are tons of VMs that are setup to be intentionally vulnerable to different techniques or attacks. You load the VM and pretend it’s a server you want to attack and follow your standard hacking protocols. Some are setup to be boot to root challenges where you ‘win’ when you get root and some are setup with flags that you can find hidden in the target worth points. There are in person and online CTFs and they’ve gotten pretty popular with the National Cyber League being a major competition. Some are easy, some are really hard and most have really good write-ups that can teach you so much about INFOSEC, penetration testing and actually let you practice the techniques in a relatively easy and legal way.

                                                            \n

                                                            Where steganography comes in to this discussion is that it’s an element you sometimes see used in the kinds of challenges I mentioned previously and also in alternate reality games, online recruitment challenges by national agencies/big tech companies and militarys. They are even used in real world espionage and intelligence work or super spooky secret challenges like Cicada 3301.

                                                            \n

                                                            Simply put steganography (and I’m pasting this straight out of Wikipedia): “is the practice of concealing a file, message, image, or video within another file, message, image, or video”. Steganography is used to hide secrets in plain sight. It’s a way to send a message, without anyone detecting that a message is even being sent.

                                                            \n

                                                            I’ll give you more examples in the next section, but imagine a letter that has a secret written in invisible ink. Only the sender and receiver should know about the invisible ink and any eavesdroppers should be none the wiser. This simple example has been used by countless prisoners whose mail is routinely read and examined. Terrorists and spies the world over also use steganography and are known to embed messages in an image and post it online. With how many image hosting sites there are, with millions of people posting to them billions of images day in and day out, you can see why steganography can be such a challenge to combat. Before I move on to some more specific examples I want to stress again that I’m not an expert on cryptography or steganography. While researching for this podcast it’s overwhelmingly clear that you could spend your whole career focused on only steganography. This talk is just a primer on the subject and only the tip of the iceberg.

                                                            4. Why should we care?

                                                            \n

                                                            When we are doing a CTF or crypto challenge and are presented with an image or media file we are pretty well assured there’s something in there, though not every image you find while doing a challenge or CTF will utilize steganography so don’t overanalyze. I’ve known people who are really into alternate reality games spending 100s of hours doing spectrographic analysis and for our purpose(and the scope of this podcast), there should be some clue that steganography is being used. The challenge then becomes how we direct our work flow as to not waste any time and be the most efficient in cracking that particular part the puzzle. There are MANY stego tools out there, some of them homebrewed, and unless the designer of the challenge puts in a clue, you might spend hours trying different algorithms or tools. And even if you do, there’s no guarantee you’ll get anything at all. A lot of the tools that will be mentioned in the next section rely on fingerprinting how known algorithms process data. This is not only a big problem for hackers like us with our CTFs and games, but even more so for governments who are charged with keeping us safe. So if you’re looking at possible steganography, you need to build a good workflow and I noticed a post on Reddit a few weeks ago with a user asking about image forensics. There was a comment posted that was so good I forwarded it to my hacking friends and it inspired me to do this podcast. I’m using the comment as a potential framework for my own personal work with images and steganography. It helped me to develop my own protocol and I wanted to share it with you all and if anyone wants to expand on it or improve it please do so. Thank you /u/Alexeyan!

                                                            \n

                                                            This is coming straight out of the post on Reddit. I thought about rewriting it, but it didn’t seem necessary and I will be giving the author full credit. I add a couple more tools on at the bottom and a few closing thoughts:

                                                            \n
                                                              \n

                                                            • First: Look at the image. Maybe it tells you something important.

                                                              • \n

                                                            • Use binwalk to check for other file type signatures in the image file.

                                                              • \n

                                                            • Use Exiftool to check for any interesting exif-metadata.

                                                              • \n

                                                            • Use stegsolve and switch through the layers and look for abnormalities.

                                                              • \n

                                                            • Maybe the Flag is painted in the LSB image, or some QR-Code.

                                                              • \n

                                                            • Maybe there are random pixels that look strange in a certain layer, that’s a hint for Bit-Stego.

                                                              • \n

                                                            • Use zsteg to automatically test the most common bitstegos and sort by %ascii-in-results. (This one auto-solves about 50% of all image stego challenges)

                                                              • \n

                                                            • If the file is a png, you can check if the IDAT chunks are all correct and correctly ordered.

                                                              • \n

                                                            • Check with the strings tool for parts of the flag. If you found for example “CTF{W” in a chunk, check what is on that position in other IDAT chunks.

                                                              • \n

                                                            • The harder ones can be a lot more tricky though.. JPG coefficiency manipulation, Frequency analysis, …

                                                              • \n

                                                            • But usually those are frowned upon, because they require a lot of guessing (if no hiding tool is provided)

                                                              • \n

                                                            Detecting steganography is hard work. There are computer scientists who do only this. While we aren’t at that level for the information being presented here, it will require a lot of digging and trying different tools. Hopefully following these steps will help identify the more common techniques in an easier way than trial and error.

                                                            \n

                                                            One last thing I want to mention is that part of how I see detecting steganography in CTFs or cyptochallenges is having a certain mindset and always looking at things in various layers. I try to look at everything within the challenge as if there could be something right in front of my eyes. I mentally flip through different layers and see the codes within the codes. And remember if you’re playing an alternate reality game, a CTF or a crypto challenge, generally speaking, the designers want you to play through the game. They will leave clues if you need them. They want the players to get to the end. Don’t overthink things.

                                                            \n

                                                            In this case, it’s probably better to unsolder the header, and solder a right angle header in place, so the pins are pointing to the side of the board and not upwards

                                                            \n

                                                            \n

                                                            With a bit of caution and the help of some desoldering wick, it’s not a complex operation, because there is no component near the GPIO header.

                                                            \n

                                                            Of course if you plan on using a HAT, then you’re better off using the straight header. The Raspberry Pi 3A+ is actually the same size than a standard HAT.

                                                            Since the Raspberry Pi 3A+ doesn’t have an ethernet port, I think I will not use it for server stuff like Mosquitto or Pi-Hole, for which a good network connection is required. Also, those servers sometimes need a keyboard and a mouse, and with only one USB port, that’s not too practical.

                                                            \n

                                                            For me, the A+ will be used to upgrade projects currently using a Raspberry Pi ZeroW, and for which I need a little more power. The on board WiFi and the small form factor, combined with the extra power, makes the 3A+ an ideal replacement for the ZeroW.

                                                            Raw resources are integral part for most 4x games. Here’s one way of modeling them in Haskell. I wanted a system that is easy to use, doesn’t require too much typing and is type safe.

                                                            \n

                                                            RawResource is basic building block:

                                                            \n
                                                            newtype RawResource a = RawResource { unRawResource :: Int }\n    deriving (Show, Read, Eq)
                                                            \n

                                                            It can be parametrised with anything, but I’m using three different types:

                                                            \n
                                                            data Biological = Biological\ndata Mechanical = Mechanical\ndata Chemical = Chemical
                                                            \n

                                                            Example of defining harvest being 100 units of biological raw resources:

                                                            \n
                                                              harvest :: RawResource Biological\n  harvest = RawResource 100
                                                            \n

                                                            Raw resources are often manipulated (added and subtracted mostly). Defining Num instance allows us to use them as numbers:

                                                            \n
                                                            instance Num (RawResource t) where\n    (+) (RawResource a) (RawResource b) = RawResource $ a + b\n    (-) (RawResource a) (RawResource b) = RawResource $ a - b\n    (*) (RawResource a) (RawResource b) = RawResource $ a * b\n    abs (RawResource a) = RawResource $ abs a\n    signum (RawResource a) = RawResource $ signum a\n    fromInteger a = RawResource $ fromInteger a
                                                            \n

                                                            For example, adding harvest to stock pile:

                                                            \n
                                                              stock :: RawResource Biological\n  stock = RawResource 1000\n\n  harvest :: RawResource Biological\n  harvest = RawResource 100\n\n  newStock = stock + harvest
                                                            \n

                                                            Comparing size of two resource piles is common operation. Ord instance has methods we need for comparing:

                                                            \n
                                                            instance Ord (RawResource t) where\n    (<=) (RawResource a) (RawResource b) = a <= b
                                                            \n

                                                            One function is enough, as rest is defined in terms of it. Sometimes (usually for reasons of optimization), one might want to define other functions too.

                                                            \n

                                                            Another way to add bunch of resources of same type together is defining Monoid instance:

                                                            \n
                                                            instance Semigroup (RawResource t) where\n    (<>) a b = a + b\n\ninstance Monoid (RawResource t) where\n    mempty = RawResource 0
                                                            \n

                                                            For example, combining harvests of many fields can be achieved as:

                                                            \n
                                                              harvests :: [RawResource Biological]\n  harvests = [RawResource 20, RawResource 50, RawResource 25]\n\n  total :: RawResource Biological\n  total = mappend harvests
                                                            \n

                                                            All these functions keep track of type of resources being manipulated. Compiler will emit an error if two different types of resources are being mixed together.

                                                            \n

                                                            Raw resources are often grouped together for specific purpose. This again uses phantom types to keep track the intended usage:

                                                            \n
                                                            data RawResources a = RawResources\n    { ccdMechanicalCost :: RawResource Mechanical\n    , ccdBiologicalCost :: RawResource Biological\n    , ccdChemicalCost :: RawResource Chemical\n    } deriving (Show, Read, Eq)\n\ndata ResourceCost = ResourceCost\ndata ConstructionSpeed = ConstructionSpeed\ndata ConstructionLeft = ConstructionLeft\ndata ConstructionDone = ConstructionDone\ndata ResourcesAvailable = ResourcesAvailable
                                                            \n

                                                            And in order to be able to combine piles of RawResources, we’ll define Semigroup and Monoid instances. Notice how both instances make use of Semigroup and Monoid instances of RawResource:

                                                            \n
                                                            instance Semigroup (RawResources t) where\n    (<>) a b = RawResources\n        { ccdMechanicalCost = ccdMechanicalCost a <> ccdMechanicalCost b\n        , ccdBiologicalCost = ccdBiologicalCost a <> ccdBiologicalCost b\n        , ccdChemicalCost = ccdChemicalCost a <> ccdChemicalCost b\n        }\n\ninstance Monoid (RawResources t) where\n    mempty = RawResources\n        { ccdMechanicalCost = mempty\n        , ccdBiologicalCost = mempty\n        , ccdChemicalCost = mempty\n        }
                                                            \n

                                                            For those interested seeing some code, source is available at https://github.com/Tuula/deep-sky/ (https://github.com/Tuula/deep-sky/tree/baa0807dd36b61fd02174b17c10013862af4ec18 is situation before lots of Elm related changes that I mentioned in passing in the previous episode)

                                                            The wings of aircraft do not stall all at once. They are designed (usually) to stall from the wing root (where the wing is attached to the fuselage) towards the tips. This ensures good roll control at slow speed and into the stall. This stalling characteristic is achieved by designing twist in the wing (washout) allowing different parts of the wing to hit the critical angle of attack at different times.

                                                            \n

                                                            The most dangerous situation that you can find yourself in is a low altitude situation where one wing is stalled more than the other. The airplane then enters a spin. The dangerous part is the low altitude. Spins are fun, and the plane is still controllable, but you need altitude to recover. A wise man told me when turning low to the ground keep your nose down and speed up.

                                                            \n

                                                            Most light aircraft will shudder or buffet as you approach the critical angle of attack this happens because of the disturbed airflow hitting the aircraft’s fuselage or tail. In larger aircraft no (i.e. airliners) no feel is given naturally as the plane approaches a stalled condition so systems like stick shakers vibrate the control artificially as you approach the critical angle of attack as measured by the AoA sensors. DC-9 stick shaker, a big cell phone vibrator artificial stall warning is mandatory in fly-by-wire aircraft (i.e. Airbus, f-16) as well as pure hydraulic controls (i.e. Boeing 757)

                                                            Hello and welcome to Hacker Public Radio, I’m Edward Miro and for this episode I decided to address mobile device security. As with most of the research and articles I’ve written in the past, these are geared toward standard users in a business setting and are meant to be a jumping off point for further research and to be a foundation for cyber security 101 level training classes. If you like what I do, and want to have me come speak to your team, feel free to email me.

                                                            \n

                                                            As an information security researcher, I have noticed a trend in what potential clients lately have been interested in: cell phones. Almost everyone I have consulted for in the area of private investigations make this area their main priority. This makes sense as users have started to transition to using mobile devices more and more. Not only do cell phones represent the main conduit to the internet for a huge chunk of people, but many use them for work also. Many companies have smartly presented policies against this, but there are still many organizations that allow bring-your-own-device style implementations. In the following podcast I will try to define the threats, defense and considerations in very broad strokes.

                                                            \n

                                                            Cell phones differ from a standard hacking target in a few ways. For the most part, many of the same vectors are still valid. Remote code execution however is more rare, but not out of the question. I’m going to attempt to present these different vectors in an ascending list of what is most likely to be used as an attack, in my humble (and possibly ignorant) opinion.

                                                            This vector is one many in the hacking world will already be familiar with and it is a major concern for mobile devices as well. Attackers can monitor an access point where the mobile device is connected and collect packets in all the usual ways. Open public WiFi is a treasure trove and tons of data that’s being sent in the clear can be collected, analyzed and leveraged by attackers.

                                                            \n

                                                            Defense here is a bit more complicated for the general user, but shouldn’t be too intrusive for most:

                                                            \n
                                                              \n
                                                            1. Use a VPN on your mobile devices.
                                                              2. \n
                                                            2. Switch to a DNS provider that provides secure DNSSEC.
                                                              3. \n
                                                            3. Implement proper encryption on access points.
                                                              4. \n
                                                            \n

                                                            2. Spyware

                                                            \n

                                                            Many commercial spyware applications are readily available on both of the main app stores. The challenges for attackers lie in either gaining physical access to the unlocked device to install the spyware, or tricking the user into installing it themselves. Most often the target’s spouse or close contact does this. Some of these apps can be disguised to look like innocuous applications as a feature, but with devices that are rooted/jailbroken, they can be completely hidden from the user. I found a few surveys that state the average smart phone user has about 30 apps installed. I don’t think it’s unreasonable to suspect the average person wouldn’t notice a second calculator or calendar app. These apps feature the full gamut of what you’d expect from a spyware app.

                                                            \n

                                                            Defense against spyware is pretty simple:

                                                            \n
                                                              \n
                                                            1. Don’t allow unsupervised access to your device.
                                                              2. \n
                                                            2. Use a strong passcode or biometric lock.
                                                              3. \n
                                                            3. Remove unused applications and be aware of new apps that may pop up.
                                                              4. \n
                                                            4. Don’t root or jailbreak your device.
                                                              5. \n
                                                            \n

                                                            3. Social Engineering

                                                            \n

                                                            The tried and true vector that has always worked and will continue to work is social engineering. It doesn’t matter what kind of device a target is using if you can get them to click a malicious link, open a malicious attachment, or disclose their password to the attackers. With a user’s password you can conduct a vast amount of surveillance through their Google or Apple account. Not to mention leverage their password into all their other accounts as most users still use the same password for everything. We can also callback to the previous section on spyware by mentioning that many users are already familiar with enabling the installation of 3rd party applications and can be tricked into installing a cleverly disguised spyware application.

                                                            \n

                                                            Basic OPSEC recommendations are applicable here:

                                                            \n
                                                              \n
                                                            1. Don’t click strange or unsolicited links or attachments on your devices.
                                                              2. \n
                                                            2. Never disclose your password to anyone through a text message or voice call.
                                                              3. \n
                                                            3. Don’t install 3rd party applications. I’ll extend this to say not to install any shady or questionable apps, even ones hosted by the app stores. There have been instances of vetted apps being malicious.
                                                              4. \n
                                                            \n

                                                            4. IMSI catchers/Femtocells

                                                            \n

                                                            I refer to these as DIY Stingrays. Stingrays are devices used by law enforcement to track and surveil cell phone traffic. These devices emulate a cell tower or boost cell phone signals when used in a legitimate way. Mobile phones are designed to prefer using stations that are the closest and strongest. Any technically proficient attacker can DIY one of these devices for not a lot of money. When an attacker deploys one of these devices, the target’s phone usually has no idea that the device isn’t an official cell tower and happily connects and passes traffic through it. The rogue stations can then be configured to pass the traffic on to an authentic tower and the user will have no idea. These rogue towers can not only collect identifying information about the mobile device that can be used to track or mark a target, they can also monitor voice calls, data, and SMS, as well as perform man-in-the-middle attacks. Often they can disable the native encryption of the target’s phone as well.

                                                            \n

                                                            Defense against this vector is a bit more complicated:

                                                            \n
                                                              \n
                                                            1. As before, use a VPN.
                                                              2. \n
                                                            2. Use Signal or other encrypted communication apps.
                                                              3. \n
                                                            3. Avoid disclosing sensitive information during voice calls.
                                                              4. \n
                                                            4. There is software that has been developed to detect and notify the user when a rogue station has been detected, but this is not going to be super helpful for standard users. There are also maps online of known cell towers and it is possible to use software to identify your connected tower.
                                                              5. \n
                                                            \n

                                                            5. Exploits

                                                            \n

                                                            Speaking very generally, this attack vector is for the most part less of a concern (depending on your particular threat level), but we all know that the chance of this happening in the wild is probably remote for most people. The technical implementations of exploits such as Rowhammer, Stagefright, and Blueborne are well outside the scope of this particular talk, but we would be incorrect to not mention them and what can be done to protect against them. And we should also pay special attention to more and more exploits being developed to attack mobile devices as attackers have started putting a lot of attention in this area. Even though many of these vulnerabilities are being patched, we all know many users are still using old versions of Android and iOS, and many devices are simply outside the support period offered by the manufacturers and will never be updated past a certain point. Couple that with the general idea that mobile devices (or any device running a non Windows based OS) are “safer” because less exploits exist for them is currently a very poor assumption. This will probably get worse as the cost of keeping up with new devices now being over $1000 and many users won’t be able to get devices that are constantly being patched.

                                                            \n

                                                            What we can do:

                                                            \n
                                                              \n
                                                            1. Keep your mobile devices updated with most current OS updates and carrier settings. Also keep applications updated. I don’t know how many times I’ve noticed friends or family with devices that are ready to be updated, but the notifications go ignored.
                                                              2. \n
                                                            2. If it’s possible, replace devices when they are outside the support period.
                                                              3. \n
                                                            3. Be paranoid, if it applies to you. What this means is when you use any computer or device, always remember that zero day exploits can exist for years before being disclosed. You could follow ALL the best OPSEC practices, and you could still be vulnerable to exploits that haven’t been disclosed and/or patched. This might not matter if you’re just a general user, but if you work for the government or do intelligence work, act as if.
                                                              4. \n
                                                            \n

                                                            Well, thank you for taking the time to listen to my basic introduction to cell phone cyber defense. I know most of the information I provided is only the tip of the iceberg and if current trends hold up, this will only get worse in the future. If you want to add to or correct any mistakes I may have made, like I stated in the introduction, feel free to email me and let’s have a conversation. I don’t claim to know all there is to know and love feedback and any opportunities to learn more or collaborate with others in the field.

                                                            \n

                                                            \nI had a very similar problem to Ahuka aka Kevin, in hpr2675 :: YouTube Playlists. I wanted to be able to download an entire youtube channel and store them so that I could play them in the order that they were posted.
                                                            \nSee previous episode hpr2710 :: Youtube downloader for channels.\n

                                                            \n

                                                            \nThe problem with the original script is that it needs to download and check each video in each channel and it can crawl to a halt on large channels like EEEVblog.\n

                                                            \n

                                                            \nThe solution was given in hpr2544 :: How I prepared episode 2493: YouTube Subscriptions - update with more details in the full-length notes.\n

                                                            \n\n

                                                              Subscriptions are the currency of YouTube creators so don't be afraid to create an account to subscribe to the creators. Here is my current subscription_manager.opml to give you some ideas.

                                                            How it works

                                                            \n

                                                            \nThe first part allows you to define where you want to save your files. It also allows you to set what videos to skip based on length and strings in their titles.\n

                                                            \n
                                                            \nsavepath=\"/mnt/media/Videos/channels\"\nsubscriptions=\"${savepath}/subscription_manager.opml\"\nlogfile=\"${savepath}/log/downloaded.log\"\nyoutubedl=\"/mnt/media/Videos/youtube-dl/youtube-dl\"\nDRYRUN=\"echo DEBUG: \"\nmaxlength=7200 # two hours\nskipcrap=\"fail |react |live |Best Pets|BLOOPERS|Kids Try\"\n
                                                            \n\n

                                                            \nAfter some checks and cleanup, we can then parse the opml file. This is an example of the top of mine.\n

                                                            \n
                                                            \n<?xml version=\"1.0\"?>\n<opml version=\"1.1\">\n  <body>\n    <outline text=\"YouTube Subscriptions\" title=\"YouTube Subscriptions\">\n      <outline text=\"Wintergatan\" title=\"Wintergatan\" type=\"rss\" xmlUrl=\"https://www.youtube.com/feeds/videos.xml?channel_id=UCcXhhVwCT6_WqjkEniejRJQ\"/>\n      <outline text=\"Primitive Technology\" title=\"Primitive Technology\" type=\"rss\" xmlUrl=\"https://www.youtube.com/feeds/videos.xml?channel_id=UCAL3JXZSzSm8AlZyD3nQdBA\"/>\n      <outline text=\"John Ward\" title=\"John Ward\" type=\"rss\" xmlUrl=\"https://www.youtube.com/feeds/videos.xml?channel_id=UC2uFFhnMKyF82UY2TbXRaNg\"/>\n
                                                            \n\n

                                                            \nNow we use the xmlstarlet tool to extract each of the urls and also the title. The title is just used to give some feedback, while the url needs to be stored for later. Now we have a complete list of all the current urls, in all the feeds. \n

                                                            \n
                                                            \nxmlstarlet sel -T -t -m '/opml/body/outline/outline' -v 'concat( @xmlUrl, \" \", @title)' -n \"${subscriptions}\" | while read subscription title\ndo\n  echo \"Getting \"${title}\"\"\n  wget -q \"${subscription}\" -O - | xmlstarlet sel -T -t -m '/_:feed/_:entry/media:group/media:content' -v '@url' -n - | awk -F '?' '{print $1}'  >> \"${logfile}_getlist\"\ndone\n
                                                            \n\n

                                                            \nThe main part of the script then counts the total so we can have some feedback while we are running it. It then pumps the list from the previous step into a loop which first checks to make sure we have not already downloaded it.\n

                                                            \n
                                                            \ncount=1\ntotal=$( sort \"${logfile}_getlist\" | uniq | wc -l )\n\nsort \"${logfile}_getlist\" | uniq | while read thisvideo\ndo \n  if [ \"$( grep \"${thisvideo}\" \"${logfile}\" | wc -l )\" -eq 0 ];\n  then\n
                                                            \n

                                                            \nThe next part takes advantage of the youtube-dl --dump-json command which downloads all sorts of information about the video which we store to query later.\n

                                                            \n
                                                            \n    metadata=\"$( ${youtubedl} --dump-json ${thisvideo} )\"\n    uploader=\"$( echo $metadata | jq '.uploader' | awk -F '\"' '{print $2}' )\"\n    title=\"$( echo $metadata | jq '.title' | awk -F '\"' '{print $2}' )\"\n    upload_date=\"$( echo $metadata | jq '.upload_date' | awk -F '\"' '{print $2}' )\"\n    id=\"$( echo $metadata | jq '.id' | awk -F '\"' '{print $2}' )\"\n    duration=\"$( echo $metadata | jq '.duration' )\"\n
                                                            \n

                                                            \nHaving the duration, we can skip long episodes.\n

                                                            \n
                                                            \n\n    if [[ -z ${duration} || ${duration} -le 0 ]]\n    then\n      echo -e \"nError: The duration \"${length}\" is strange. \"${thisvideo}\".\"\n      continue\n    elif [[ ${duration} -ge ${maxlength} ]]\n    then\n      echo -e \"nFilter: You told me not to download titles over ${maxlength} seconds long \"${title}\", \"${thisvideo}\"\"\n      continue\n    fi\n
                                                            \n

                                                            \nOr videos that don't interest us.\n

                                                            \n
                                                            \n\n    if [[ ! -z \"${skipcrap}\" && $( echo ${title} | egrep -i \"${skipcrap}\" | wc -l ) -ne 0 ]]\n    then\n      echo -e \"nSkipping: You told me not to download this stuff. ${uploader}: \"${title}\", \"${thisvideo}\"\"\n      continue\n    else\n      echo -e \"n${uploader}: \"${title}\", \"${thisvideo}\"\"\n    fi\n
                                                            \n

                                                            \nNow we have a filtered list of urls we do want to keep. These we also save the description in a text file with the video id if we want to refer to it later. \n

                                                            \n
                                                            \n    echo ${thisvideo} >> \"${logfile}_todo\"\n    echo -e $( echo $metadata | jq '.description' ) > \"${savepath}/description/${id}.txt\"\n  else\n    echo -ne \"rProcessing ${count} of ${total}\"\n  fi\n  count=$((count+1))\ndone\necho \"\"\n
                                                            \n

                                                            \nAnd finally we download the actual videos saving each channel in its own directory. The file names is first an ISO8601 date, then the title stored as ASCII with no space or ampersands. I then use a \"⋄\" as a delimiter before the video id.\n

                                                            \n
                                                            \n\n# Download the list\nif [ -e \"${logfile}_todo\" ];\nthen\n  cat \"${logfile}_todo\" | ${youtubedl} --batch-file - --ignore-errors --no-mtime --restrict-filenames --format mp4 -o \"${savepath}\"'/%(uploader)s/%(upload_date)s-%(title)s⋄%(id)s.%(ext)s'\n  cat \"${logfile}_todo\" >> ${logfile}\nfi\n
                                                            \n

                                                            \nNow you have a fast script that keeps you up to date with your feeds.\n

                                                            Original idea I had with my toy game project was to have Yesod render most of the user interface as static HTML and have as little client side scripting as possible. Later I realized that there would be parts with significant amount of client side code and it might be better if whole site was written in Elm.

                                                            Backend is written in Haskell and front end in Elm. Communication between them is via REST interface and most of the data is in JSON. All JSON encoding / decoding is centralized (more or less), same with initiating requests to server.

                                                            \n

                                                            API Endpoints

                                                            \n

                                                            End points used for REST calls are defined in single data type that captures their name and parameters. These are used when initiating requests, meaning there’s smaller chance of typo slipping through.

                                                            \n
                                                            type Endpoint\n    = ApiStarDate\n    | ApiResources\n    | ApiStarSystem\n    | ApiStar\n    | ApiPlanet\n    | ApiPopulation PlanetId\n    | ApiBuilding PlanetId\n    | ApiConstructionQueue PlanetId\n    | ApiConstruction Construction\n    | ApiBuildingConstruction\n    | ApiAvailableBuildings
                                                            \n

                                                            For example, sending a GET request to retrieve all construction projects on a planet is done as:

                                                            \n
                                                            Http.send (ApiMsgCompleted << ConstructionsReceived) (get (ApiConstructionQueue planetId) (list constructionDecoder))
                                                            \n

                                                            GET Request is sent to ApiConstructionQueue endpoint and it has planetId as parameter. When server sends response, our program will parse content of it will be a list that is parsed with constructionDecoder and create “ApiMsgCompleted ConstructionsReceived” message with result of the parsing. Update function will process this and store list of constructions somewhere safe for further use.

                                                            \n

                                                            Update function

                                                            \n

                                                            Update function is in charge of reacting to messages (mouse clicks, page changes, responses from server). In a large program update function will quickly get big and unwieldy. Breaking it into smaller pieces (per page for example), will make maintenance easier. This way each page has their own message type and own update function to handle it. In addition there’s few extra ones (cleaning error display, processing API messages and reacting to page changes).

                                                            \n

                                                            Same way as API end points are encoded in a type, pages are too:

                                                            \n
                                                            type Route\n    = HomeR\n    | ProfileR\n    | StarSystemsR\n    | StarSystemR StarSystemId\n    | PlanetR StarSystemId PlanetId\n    | BasesR\n    | FleetR\n    | DesignerR\n    | ConstructionR\n    | MessagesR\n    | AdminR\n    | LogoutR\n    | ResearchR

                                                            routeToString function is used to map Route into String, that can be placed in hyperlink. Below is an excerp:

                                                            \n
                                                            routeToString : Route -> String\nrouteToString route =\n    case route of\n        HomeR ->\n            "/home"\n\n        StarSystemR (StarSystemId sId) ->\n            "/starsystem/" ++ String.fromInt sId\n\n        PlanetR (StarSystemId sId) (PlanetId pId) ->\n            "/starsystem/" ++ String.fromInt sId ++ "/" ++ String.fromInt pId
                                                            \n

                                                            Because mapping needs to be bi-directional (Route used to define content of a href and string from a href used to define Route), there’s mapping to other direction too:

                                                            \n
                                                            routes : Parser (Route -> a) a\nroutes =\n    oneOf\n        [ map HomeR top\n        , map ProfileR (s "profile")\n        , map ResearchR (s "research")\n        , map StarSystemsR (s "starsystem")\n        , map StarSystemR (s "starsystem" </> starSystemId)\n        , map PlanetR (s "starsystem" </> starSystemId </> planetId)\n        , map BasesR (s "base")\n        , map FleetR (s "fleet")\n        , map DesignerR (s "designer")\n        , map ConstructionR (s "construction")\n        , map MessagesR (s "message")\n        , map AdminR (s "admin")\n        , map LogoutR (s "logout")\n]
                                                            \n

                                                            Result of parsing is Maybe Route, meaning that failure will return Nothing. Detecting and handling this is responsibility of the calling code, usually I just default to HomeR.

                                                            \n

                                                            \n

                                                            Borrowing from Yesod, client uses recursive function to define breadcrumb path. This is hierarchical view of current location in the application, allowing user to quickly navigate backwards where they came.

                                                            \n

                                                            Breadcrumb path consists of segments that are tuple of (String, Maybe Route). String tells text to display and Route is possible parent route of the segment. This allows hierarchical definition: “Home / Star systems / Sol / Earth”. Because route has only (for example) PlanetId, we need to pass Model too, so that the data retrieved from server can be used to figure out what name such a planet has.

                                                            A DIN Rail is a metal rail for mounting pieces of electrical equipment inside an equipment rack, for performing tasks in a building, in a machine, and so forth. It’s common to see DIN rails holding circuit breakers for example.

                                                            \n

There are also designs for mounts onto which devices like Raspberry Pis and disks can be fitted and attached to a rail.

                                                            In practise, I don't even use the shutdown command. I use poweroff, which does a shutdown and poweroff.

                                                            \n

                                                            Hello and welcome to Hacker Public Radio, I’m Edward Miro and for this episode I decided to record an episode on the importance of good passwords. This will be part one in a series of podcasts I’m going to call “Information Security for Everyone”. As with most of the content I create in the world of infosec, my goal is to present the information in a way that a majority of people can get value from it and anyone can play this for a friend, colleague or family member and make it easy for the non-hackers in our lives to understand.

                                                            \n

                                                            Passwords

                                                            \n

                                                            One of the first things most people think about when it comes to online safety is their password. We all know that passwords are to our online accounts what keys are for our locks. Would you use the same key for your house, your car, your office and your safety deposit box? Of course not. And if you did, what would happen if a bad guy could get a copy of just that one key? They’d have access to everything. With so much of our personal, confidential, financial and medical information accessible from our various online accounts, what can we do to make things as safe as possible?

                                                            \n

                                                            For me personally I employ and advise a three faceted approach:

                                                            \n
                                                              \n
                                                            1. Complex passwords
                                                              2. \n
                                                            2. Unique passwords
                                                              3. \n
                                                            3. Two-factor authentication (where available)
                                                              4. \n
                                                            \n

                                                            Clearly the solution is to use a unique password for each account and make them complicated enough that an attacker couldn’t guess it or crack it in an amount of time that would be actionable. One problem this presents to general users is the inconvenience and difficulty in remembering these passwords or storing them in a secure way. This leads into my first bit of advice:

                                                            \n

                                                            Password Managers

                                                            \n

                                                            My recommendation is to use a password manager. I’m going to make references to managers such as LastPass because that’s the one I’ve always used, but I’m not saying it’s the best or would be the best for you. There are many great options and I would rather people use the one that works the best for them and not merely the one I like best. Anyways. Applications like LastPass give you the ability to store all passwords in your encrypted “vault” and then request them through browser add-ons or standalone applications. They also have built in features that allow you to generate secure passwords at any length or complexity.

                                                            \n

                                                            When using a password manager, all you have to remember is your ONE master password. When you sign in, the manager can then decrypt all your saved passwords and let you use them. When I sign up for a website, I use LastPass to generate the longest and most complex password supported by the site and it gets stored in my vault safely for later use.

                                                            \n

                                                            There are various options online to choose from and I suggest you do some research and try a few different ones to see what is comfortable for you. One thing to consider when using a password manager is that the master password is your single point of failure and should be a long and complex password that you don’t use ANYWHERE else.

                                                            \n

                                                            If you’re wondering how to come up with a secure password that you can remember there are various strategies online, but I follow this:

                                                            \n

                                                            Take a poem, song lyrics or phrase that is easy for you to remember. For this example I’ll use the phrase:

                                                            \n
                                                            "The stars at night are big and bright. Deep in the heart of Texas."
                                                            \n

                                                            Then I take the first letters from each word and that gives me:

                                                            \n
                                                            TsanababdithoT.
                                                            \n

                                                            Then I swap out the vowels for some numbers/special characters. And that gives me:

                                                            \n
                                                            T5@n@b@bd1th0T
                                                            \n

                                                            I checked that password on Dashlane’s Password Strength Checker, and got the following results:

                                                            \n
                                                            It would take a computer about 204 million years to crack your password
                                                            \n

                                                            And that’s just an example of a very secure password that I thought up in just a few seconds that I probably won’t ever be able to forget it.

                                                            \n

                                                            2FA (two-factor authentication)

                                                            \n

                                                            Another very important recommendation I want to touch on in this episode is using two-step authentication. I use it for all accounts that offer it and it’s very easy to set-up and use. It works in tandem with an application on my mobile device called Google Authenticator(though there are others and like LastPass this is just the one I use) and it’s available for Android and iOS. After you install the app, you access the security settings for the account you want to protect and register it with your device.

                                                            \n

                                                            What it does is provide a “second” password when logging it that is only used one time. When you log in, the site will prompt for the two-step authentication code, you then open the Google Authenticator app and the code for the session will be listed. The codes are only available for a short time and are constantly changing. This makes someone gaining unauthorized access to your account VERY difficult.

                                                            \n

                                                            A few closing thoughts

                                                            \n

                                                            Some information security professionals see a password manager as insecure due to it being a single point of failure. I can understand this and would respond that although this might be true, having a complex master password and using the manager in conjunction with two-step authentication makes it a pretty safe and solid system. And even if there is a breach, none of my passwords are the same and changing them is incredibly fast and easy with a manager.

                                                            \n

                                                            Also, I usually don’t recommend keeping hard copies of passwords, but if you can guarantee the physical security of your password list, this in my opinion is preferable to using the same, insecure password for all your accounts.

                                                            \n

                                                            Please remember, if you’re like most people on the internet and you use an easy to crack password or the same password on all your sites, all it takes is one compromised account to give bad guys access to everything.

                                                            \n

                                                            I’m also including a list of links in the bottom of the show notes to everything I mentioned and also a link to the site Have I Been Pwned. This is a service that collects accounts that have been involved in hacks and lets anyone search for their email address and see if their information is already compromised. If it is, do this NOW:

                                                            \n
                                                              \n
                                                            1. Setup a password manager with a strong master password.
                                                              2. \n
                                                            2. Change all your passwords using the built in password generator in your password manager and save them in your vault as you go.
                                                              3. \n
                                                            3. In the future when breaches happen, it’s incredibly easy to change your password and you’ll also rest easy knowing that the password obtained can’t get them into anything else.
                                                              4. \n
                                                            \n

                                                            I know this will take a long time. But it’s worth it. Then, you only have to remember one master password and you will be exponentially safer online.

I hope this will help any non-hackers in your life and like I say in all my podcasts, I don’t claim to know all there is to know and love feedback and any opportunities to learn more or collaborate with others in the field. As with most of the research and articles I’ve written in the past, these are geared toward standard users in a business setting and are meant to be a jumping off point for further research and to be a foundation for cyber security 101 level training classes.

                                                            I have had problems importing vcards onto my Android phone. After a lot of troubleshooting, I tracked it down to embedded images in the card. The PHOTO;VALUE field to be precise.

In the end I tracked down a post on stackoverflow that hinted that the aspect ratio was important. And sure enough it was.

                                                            and before that, contact photos had just a size of a thumbnail - 96x96.

                                                            To use an example I took the following image and saved it as Linus_Torvalds.jpg

                                                            \n\n\n

                                                            Step one is to use the -size 256x256 option which you would think would do the scaling, but in fact it only reduces the file to 366x509 which is not what I expected.

                                                            \n\n
                                                            $ gm convert -size 256x256 \"Linus_Torvalds.jpg\" Linus_Torvalds_1.jpg
                                                            $ gm identify Linus_Torvalds_1.jpg\nLinus_Torvalds_1.jpg JPEG 366x509+0+0 DirectClass 8-bit 56.1Ki 0.000u 0m:0.000002

                                                            \n\n\n

                                                            However it appears that the option is used when creating new files, and is also used by the processor to determine the intended target size. Which is why I left it in. So what we actually need is the -resize option.

                                                            \n\n

                                                            \n\n

                                                            So this has done a good job at scaling the image down. It's now scaled correctly so that the biggest edge is scaled down to 256. In this case it was the height but the width is now shorter than what we need. We do want to maintain the aspect ratio so that we don't distort the image but 184x256 is not 1:1 aspect ratio nor is it the needed dimensions of 256x256.

                                                            \n\n

                                                            The solution to this is to use the -extent command.

                                                            \n\n
                                                            $ gm convert -size 256x256 \"Linus_Torvalds.jpg\" -resize 256x256 -extent 256x256 Linus_Torvalds_3.jpg\n$ gm identify Linus_Torvalds_3.jpg\nLinus_Torvalds_3.jpg JPEG 256x256+0+0 DirectClass 8-bit 48.0Ki 0.000u 0m:0.000001s

                                                            \n\n\n

                                                            This gives us the correct size and a 1:1 aspect ratio, but the image is left justified. To fix this we need to use the -gravity command. That needs to be the first argument of the command. Finding the correct order of the commands took some trial and error.

                                                            \n\n
                                                            $ gm convert -gravity center -size 256x256 \"Linus_Torvalds.jpg\" -resize 256x256 -extent 256x256 Linus_Torvalds_4.jpg\n$ gm identify Linus_Torvalds_4.jpg\nLinus_Torvalds_4.jpg JPEG 256x256+0+0 DirectClass 8-bit 48.5Ki 0.000u 0m:0.000001s

                                                            \n\n

                                                            Finally we remove all profile information using +profile which should make the image more generic.

                                                            \n\n

                                                            Putting it all together we get.

                                                            /api/message           ApiMessageR      GET POST\n/api/message/#NewsId   ApiMessageIdR    DELETE\n/api/icon              ApiMessageIcons  GET
                                                            \n

                                                            First one is for retrieving all messages and posting a new one. Second one is for marking one read and third one is for retrieving all icons that players can attach to messages written by them.

                                                            \n

                                                            Database

                                                            \n

                                                            Database is defined in /config/models file. For news, there’s only one table:

                                                            \n
                                                            News json\n    content Text\n    factionId FactionId\n    date Int\n    dismissed Bool\nderiving Show Read Eq
                                                            \n

                                                            Content field contains the actual news article data as serialized JSON. This allows storing complex data, without having to have lots of columns or multiple tables.

                                                            \n

                                                            Domain objects

                                                            \n

                                                            There are many kinds of messages that players might see, but we’ll concentrate on one about discovering a new planet

                                                            \n

                                                            All different kinds of articles are of same type: NewsArticle. Each different kind of article has their own value constructor (PlanetFound in this particular case). And each of those value constructors has single parameter of a specific type that holds information particular to that certain article (PlanetFoundNews in this case). Adding a new article means adding a new value constructor and record to hold the data.

                                                            \n
                                                            data NewsArticle =\n    StarFound StarFoundNews\n    | PlanetFound PlanetFoundNews\n    | UserWritten UserWrittenNews\n    | DesignCreated DesignCreatedNews\n    | ConstructionFinished ConstructionFinishedNews\n\n\ndata PlanetFoundNews = PlanetFoundNews\n    { planetFoundNewsPlanetName :: Text\n    , planetFoundNewsSystemName :: Text\n    , planetFoundNewsSystemId   :: Key StarSystem\n    , planetFoundNewsPlanetId   :: Key Planet\n    , planetFoundNewsDate       :: Int\n    }
                                                            \n

                                                            Given a News object, we can turn it into NewsArticle. These are much nicer to deal with that densely packed News that is stored in database:

                                                            \n
                                                            parseNews :: News -> Maybe NewsArticle\nparseNews =\n    decode . toLazyByteString . encodeUtf8Builder . newsContent
                                                            \n

                                                            Because parsing arbitrary JSON might fail, we get Maybe NewsArticle, instead of NewsArticle. It is possible to write the same code in longer way:

                                                            \n
                                                            parseNews news =\n    let\n        content = newsContent news\n        utf8Encoded = encodeUtf8Builder content\n        byteString = toLazyByteString utf8Encoded\n    in\n        decode byteString
                                                            \n

                                                            Similarly there’s two other functions for dealing with Entities (primary key, data - pair really) and list of Entities. Note that parseNewsEntities filters out all News that it didn’t manage to turn into NewsArticle. They have following signatures:

                                                            \n
                                                            parseNewsEntity :: Entity News -> (Key News, Maybe NewsArticle)\n\nparseNewsEntities :: [Entity News] -> [(Key News, NewsArticle)]
                                                            \n

                                                            Writing JSON encoding and decoding is tedious, template Haskell can help us here:

                                                            \n
                                                            $(deriveJSON defaultOptions ''PlanetFoundNews)\n$(deriveJSON defaultOptions ''NewsArticle)
                                                            \n

                                                            Turning Articles into JSON

                                                            \n

                                                            News articles aren’t much use if they stay on the server, we need to send them to clients too. We can’t have multiple declarations of same typeclass for any type, so we declare complete new type and copy data there before turning it into JSON and sending to client (this is one way of doing this).

                                                            \n

                                                            First step, define our types (concentrating on planet found news here):

                                                            \n
                                                            data NewsArticleDto =\n    StarFoundDto StarFoundNewsDto\n    | PlanetFoundDto PlanetFoundNewsDto\n    | UserWrittenDto UserWrittenNewsDto\n    | DesignCreatedDto DesignCreatedNewsDto\n    | ConstructionFinishedDto ConstructionFinishedNewsDto\n    deriving (Show, Read, Eq)\n\ndata PlanetFoundNewsDto = PlanetFoundNewsDto\n    { planetFoundNewsDtoPlanetName :: Text\n    , planetFoundNewsDtoSystemName :: Text\n    , planetFoundNewsDtoSystemId   :: Key StarSystem\n    , planetFoundNewsDtoPlanetId   :: Key Planet\n    , planetFoundNewsDtoDate       :: Int\n    }\n    deriving (Show, Read, Eq)
                                                            \n

                                                            We need way to move data into dto and thus define a type class for that operation:

                                                            \n
                                                            class (ToJSON d) => ToDto c d | c -> d where\n    toDto :: c -> d
                                                            \n

                                                            For more information about functional dependencies, check following links: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#extension-FunctionalDependencies and https://wiki.haskell.org/Functional_dependencies

                                                            \n

                                                            Writing instances for our type class:

                                                            \n
                                                            instance ToDto PlanetFoundNews PlanetFoundNewsDto where\n    toDto news =\n        PlanetFoundNewsDto { planetFoundNewsDtoPlanetName = planetFoundNewsPlanetName news\n                           , planetFoundNewsDtoSystemName = planetFoundNewsSystemName news\n                           , planetFoundNewsDtoSystemId = planetFoundNewsSystemId news\n                           , planetFoundNewsDtoPlanetId = planetFoundNewsPlanetId news\n                           , planetFoundNewsDtoDate = planetFoundNewsDate news\n                           }\n\ninstance ToDto NewsArticle NewsArticleDto where\n    toDto news =\n        case news of\n            (StarFound x) -> StarFoundDto $ toDto x\n            (PlanetFound x) -> PlanetFoundDto $ toDto x\n            (UserWritten x) -> UserWrittenDto $ toDto x\n            (DesignCreated x) -> DesignCreatedDto $ toDto x\n            (ConstructionFinished x) -> ConstructionFinishedDto $ toDto x
                                                            \n

                                                            Finally, we want to wrap our news into something that has all the common info (id and link to icon to show)

                                                            \n
                                                            data NewsDto = NewsDto\n    { newsDtoId    :: Key News\n    , newsContents :: NewsArticleDto\n    , newsIcon     :: Text\n    }\n    deriving (Show, Read, Eq)
                                                            \n

                                                            IconMapper knows how to turn NewsArticleDto (in this case) to corresponding link to the icon. Notice how our ToDto instance includes IconMapper in addition to Key and NewsArticle:

                                                            \n
                                                            instance ToDto ((Key News, NewsArticle), (IconMapper NewsArticleDto)) NewsDto where\n    toDto ((nId, article), icons) =\n        let\n            content = toDto article\n        in\n        NewsDto { newsDtoId = nId\n                , newsContents = content\n                , newsIcon = runIconMapper icons content\n                }
                                                            \n

                                                            Sideshow: IconMapper

                                                            \n

                                                            IconMapper is a function that knows how to retrieve url to icon that matches the given parameter (for example NewsArticleDto in this case):

                                                            \n
                                                            newtype IconMapper a =\n    IconMapper { runIconMapper :: a -> Text }
                                                            \n

                                                            One possible implementation that knows how to deal with NewsArticleDto. We have two levels of hierarchicy here, because UserNewsDto has special rules for figuring out which icon to use:

                                                            \n
                                                            iconMapper :: (Route App -> Text) -> IconMapper UserNewsIconDto -> IconMapper NewsArticleDto\niconMapper render userIconMapper =\n    IconMapper $ article ->\n        case article of\n            PlanetFoundDto _->\n                render $ StaticR images_news_planet_png\n\n            UserWrittenDto details ->\n                runIconMapper userIconMapper $ userWrittenNewsDtoIcon details\n    ...
                                                            \n

                                                            Back to JSON

                                                            \n

                                                            I wrote ToJSON and FromJSON instances by hand, because I wanted full control on how the resulting JSON looks like. It’s possible to configure how template Haskell names fields for example, but I think that writing these out couple of times is good practice and makes sure that I understand what’s going on behind the scenes if I use template Haskell later.

                                                            \n
                                                            instance ToJSON NewsDto where\n    toJSON (NewsDto { newsDtoId = nId\n                    , newsContents = contents\n                    , newsIcon = icon }) =\n        object [ "id" .= nId\n               , "contents" .= contents\n               , "tag" .= jsonTag contents\n               , "icon" .= icon\n               , "starDate" .= newsStarDate contents\n               ]\n\ninstance ToJSON PlanetFoundNewsDto where\n    toJSON (PlanetFoundNewsDto { planetFoundNewsDtoPlanetName = pName\n                               , planetFoundNewsDtoSystemId = sId\n                               , planetFoundNewsDtoPlanetId = pId\n                               , planetFoundNewsDtoSystemName = sName\n                               }) =\n        object [ "planetName" .= pName\n               , "systemName" .= sName\n               , "planetId" .= pId\n               , "systemId" .= sId\n               ]
                                                            \n

                                                            Time to put it all together

                                                            \n

                                                            Handler function authenticates user, check they’re member of a faction and then loads all the news:

                                                            \n
                                                            getApiMessageR :: Handler Value\ngetApiMessageR = do\n    (_, _, fId) <- apiRequireFaction\n    loadAllMessages fId

                                                            Hello and a belated Happy New Year to you all in HPR land, Ken has recently made a call for more shows as the queue is a little light at the moment so I was pondering what to waffle on about.

                                                            \n

                                                            You may know from a couple of my previous shows that as well as being into tech and Linux I’m also a keen Cook, and try and prepare as much of the food we eat at home from scratch as possible.

                                                            \n

                                                            One of the keys to good dishes is a base of sweated vegetables such as onion, celery carrot and garlic which when cooked in olive oil, is called a Soffritto in Italian cookery. In other parts of the Mediterranean and Latin America where Europeans settled this base to dishes may include other vegetables such as peppers, tomatoes and mushrooms, and have other names such as mirepoix (/mɪərˈpwɑː/ meer-PWAH); but the idea is the same to give a base flavour to soups, sauces, risotto and stew type dishes.

                                                            \n

                                                            Although not called the same thing this is also replicated in Asian cookery where spices and other aromatics are included such as ginger, lemon grass, chillies, cumin and coriander seeds.

                                                            \n

                                                            While it is not obligatory to start dishes in such a way if you do use a base of flavours like this when cooking you will find that the finished dish has a more complex and deep flavour at the end, so if you don’t do this give it a try.

                                                            \n

                                                            A simple starter is to make a tomato sauce for pasta using a base of finely chopped onion, celery, carrot and garlic soften all the vegetables in a pan with some olive oil, add a tin of tomatoes or jar of passata (sieved tomatoes) reduce for 10-15 minutes until all the flavours combine and use as a sauce over pasta with grated cheese.

                                                            \n

                                                            On January 4th 2019 Ken Fallon did a great show entitled hpr2720 :: Download youtube channels using the rss feeds where he presented a Bash script called youtube-rss.bash for managing YouTube downloads through RSS feeds.

                                                            \n

                                                            Ken said he welcomed constructive feedback ☺

                                                            \n

                                                            When I see a Bash script these days I usually find myself looking for ways to rewrite it to make it fit in with what I have been learning while doing my Bash Tips sub-series. Either that or I find it’s got some better ideas than I’ve been using which I have to find out about.

                                                            \n

                                                            I also spend time going over my own old scripts (I was writing them in the 1990’s in some cases) and trying to incorporate newer Bash features.

                                                            \n

                                                            Suffice it to say that I spotted some areas for improvement in Ken’s script and thought this might be the way to share my thoughts about them. We’re low on shows as I write this, so that gave me more motivation to make a show rather than add a comment or send Ken an email.

                                                            \n

                                                            I've had this Pioneer RT-707 reel-to-reel tape deck for something like 10 years, but only recently started using it with enthusiasm. In this episode I talk about the tape deck, about the technology, and about my memories of using this kind of audio tape as a kid. I demonstrate playback of one of my parents' mix tapes, and I also used this machine to record the last few minutes of the podcast onto a reel to reel tape, which of course I then had to transfer back to digital before submitting the show.

                                                            Hi again, this is Tony Hughes from Blackpool in the UK. Ken is still short of shows so here is another quick show to help out with the queue.

                                                            \n

                                                            This one is going to be about the applications I use on my Linux Mint 19.1 install. I’ve been using Linux for over 10 years now and during that time have never felt that there was anything that was lacking in the software department for day to day productivity and general day to day use, so this is just a list of some of the things that I, and I suspect most computer users, need to make electronic life a reality.

                                                            \n

                                                            So for internet browsing I use Firefox, I’ve been using this since my Windows days and it was just natural that, as this is the default web browser in Linux Mint, that this is what I would continue to use when I moved over to Linux.

                                                            \n

                                                            Email – I have several web based accounts which means these are operating system agnostic, but for my Internet Service provider account I use Thunderbird to download and store my e-mail onto my main desktop PC. I can also use this to access my web based accounts and store emails for these off line as well if needed.

                                                            \n

                                                            Office productivity is provided for with LibreOffice which is a very mature and comprehensive office suite comprising of all the main tools needed such as a word processor, spreadsheet and presentation software. It also has a Database and drawing package, and for maths geeks an advanced maths formula creating program which I have never used, but could be very useful for students and scientists.

                                                            \n

                                                            For audio and video playback I use VLC which again is something I first used back in my windows days, it works with all the audio and video codecs you can throw at it, and if you have the Libdvdcss codecs installed will play proprietary DVD’s.

                                                            \n

                                                            For recording and editing audio including this podcast I use Audacity, which is again a cross platform programme and a very powerful piece of software, as myself and many others that use it will be able to tell you

                                                            \n

                                                            So that is a short list of the programmes that I use on a day to day basis. I hope you found it useful, if not it doesn’t matter as Ken still got a show out of me.

                                                            \n

                                                            Well that’s it for this one. This is Tony Hughes signing off for now.

                                                            In the last show we continued with the subject of parameter expansion in the context of arrays. There are other aspects of this that could be looked at, but we’ll leave it for the moment and may revisit it in the future.

                                                            \n

                                                            In this episode we will look in more depth at the declare (typeset) built in command and at some commands that are related (readonly and local), We will also look at the commands that assist with loading data into arrays: mapfile (readarray) and read.

                                                            Here are the changes since I recorded this show in November 2017, it is now October 2018.

                                                            Think there was a £4,500 pound grant on new EV cars however it has been announced that this grant will in the near future will be cut to £3500.

                                                            \n

                                                            I think the Government and Nissan together had a £2000 contribution scheme when you traded in an old car for a 2nd hand leaf I think this is no longer available now that the leaf is more popular.

                                                            \n

                                                            Fuel costs have gone up and I may have miscalculated I think my true annual fuel bill is nearer to £2,000

                                                            \n

                                                            Nissan leaf road tax is free

                                                            \n

                                                            Because of supply and demand the depreciation situation has completely changed had I bought this leaf in November 2017 it would now be worth more today in October 2018. Only time will tell how it all pans out, things are changing rapidly.

                                                            \n

                                                            After further investigation it looks like battery degradation is less than I first thought and would likely still be in pretty good condition at 6 years old, particularly in a cooler country like here in the UK in Scotland.

                                                            \n

                                                            There has been some controversy about the new 40kw leaf which may also impact in the older leaf making the older leaf’s more appealing contributing further to the high demand for the older 30kw and 24kw leafs.

                                                            Intro

                                                            \n

                                                            I was tasked to write kragii worms in the game and informed that they’re small (10cm / 4 inches) long worms that burrow in ground and are drawn to farming fields and people. They’re dangerous and might eat harvest or people.

                                                            \n

                                                            Special events build on top of the new system I explained in episode 2733. They are read from same API as regular news and need same ToJSON, FromJSON, ToDto and FromDto instances as regular news (for translating them data transfer objects and then into JSON for sending to client).

                                                            \n

                                                            Loading

                                                            \n

                                                            Starting from the API interface, the first real difference is when JSON stored into database is turned into NewsArticle. Two cases, where special news have available options added to them and regular news are left unchanged. These options tell player what choices they have when dealing with the situation and evaluated every time special event is loaded, because situation might have changed since special event got stored into database and available options might have changed.

                                                            \n
                                                            addOptions (key, article) = case article of\n                                Special news ->\n                                    (key, Special $ availableOptions news)\n                                _ ->\n                                    (key, article)\n\navailableOptions :: SpecialNews -> SpecialNews\navailableOptions x =\n    case x of\n        KragiiWorms event _ choice ->\n            KragiiWorms event (eventOptions event) choice
                                                            \n

                                                            eventOptions is one of the events defined in SpecialEvent type class that specifies two functions every special event has to have. eventOptions lists what options the event has currently available and resolveEvent resolves the event according to choice user might have made (hence Maybe in it).

                                                            \n

                                                            Type class is parametrized with three types (imaginatively named to a, b and c). First is data type that holds information about special event (where it’s happening and to who for example), second one is one that tells all possible choices player has and third one lists various results that might occur when resolving the event. In this example they’re KragiiWormsEvent, KragiiWormsChoice and KragiiResults.

                                                            \n
                                                            data KragiiWormsEvent = KragiiWormsEvent\n    { kragiiWormsPlanetId   :: Key Planet\n    , kragiiWormsPlanetName :: Text\n    , kragiiWormsSystemId   :: Key StarSystem\n    , kragiiWormsSystemName :: Text\n    , kragiiWormsDate       :: Int\n    }\n\ndata KragiiWormsChoice =\n    EvadeWorms\n    | AttackWorms\n    | TameWorms\n\ndata KragiiResults =\n    WormsStillPresent\n    | WormsRemoved\n    | WormsTamed\n    | CropsDestroyed (RawResource Biological)\n    | FarmersInjured
                                                            \n

                                                            Definition of the SpecialEvent type class is shown below. Type signature of resolveEvent is gnarly because it’s reading and writing database.

                                                            \n
                                                            class SpecialEvent a b c | a -> b, a -> c where\n    eventOptions :: a -> [UserOption b]\n    resolveEvent :: ( PersistQueryRead backend, PersistQueryWrite backend\n                    , MonadIO m, BaseBackend backend ~ SqlBackend ) =>\n                    (Key News, a) -> Maybe b -> ReaderT backend m (Maybe EventRemoval, [c])
                                                            \n

                                                            One more piece we need is UserOption. This records options in a format that is useful in the client side. Each option player has are given title and explanation that are shown on UI.

                                                            \n
                                                            data UserOption a =\n    UserOption { userOptionTitle :: Text\n               , userOptionExplanation :: [Text]\n               , userOptionChoice :: a\n               }
                                                            \n

                                                            Current implementation of eventOptions doesn’t allow database access, but I’m planning on adding that at the point where I need it. Example doesn’t show all different options, as they all have same structure. Only first option in the list is shown:

                                                            \n
                                                            eventOptions _ = [ UserOption { userOptionTitle = "Avoid the worms"\n                              , userOptionExplanation = [ "Keep using fields, while avoiding the worms and hope they'll eventually leave."\n                                                        , "50 units of biologicals lost"\n                                                        , "25% chance of worms leaving"\n                                                        ]\n                              , userOptionChoice = EvadeWorms\n                            }\n                   , ...\n                   ]
                                                            \n

                                                            Making choice

                                                            \n

                                                            putApiMessageIdR handles updating news with HTTP PUT messages. First steps is to check that caller has autenticated and retrieve id of their faction. News article that is transferred in body as JSON is parsed and checked for type. Updating regular news articles isn’t supported and is signaled with HTTP 403 status code. One more check to perform is to check that news article being edited actually belong to the faction player is member of. If that’s not the case HTTP 404 message is returned.

                                                            \n

                                                            If we got this far, news article is updated with the content sent by client (that also contains possible choice made by user). There’s no check that type of news article doesn’t change or that the option selected doesn’t change (I need to add these at later point). In the end, list of all messages is returned back to the client.

                                                            \n
                                                            putApiMessageIdR :: Key News -> Handler Value\nputApiMessageIdR mId = do\n    (_, _, fId) <- apiRequireFaction\n    msg <- requireJsonBody\n    let article = fromDto msg\n    _ <- if isSpecialEvent article\n            then do\n                loadedMessages <- runDB $ selectList [ NewsId ==. mId\n                                                     , NewsFactionId ==. fId ] [ Asc NewsDate ]\n                if length loadedMessages == 0\n                    then apiNotFound\n                    else runDB $ update mId [ NewsContent =. (toStrict $ encodeToLazyText article) ]\n            else apiForbidden "unsupported article type"\n    loadAllMessages fId
                                                            \n

                                                            Resolving event

                                                            \n

                                                            Special event occured, user made (or did not) a choice. Now it’s time to simulate what happens. Below is resolveEvent for kragii attack.

                                                            \n
                                                            resolveEvent keyEventPair (Just choice) =\n    runWriterT . runMaybeT $\n        case choice of\n                EvadeWorms ->\n                    chooseToAvoid keyEventPair\n\n                AttackWorms ->\n                    chooseToAttack keyEventPair\n\n                TameWorms ->\n                    chooseToTame keyEventPair\n\nresolveEvent keyEventPair Nothing =\n    runWriterT . runMaybeT $ noChoice keyEventPair
                                                            \n

                                                            runWriterT and runMaybeT are used as code being called uses monad transformers to add some extra handling. WriterT adds ability to record data (KragiiResult in this case) and MaybeT adds ability to stop computation early if one of the steps return Nothing value.

                                                            \n

                                                            Let’s walk through what happens when user has chosen to avoid kragii worms and keep working only part of the fields. First step is to load faction information. If faction couldn’t be found, we abort. Next amount of biological matter consumed and how much is left is calculated. Again, if calculation isn’t possible, we’ll abort. This step reaches into database and updates amount of biological matter stored by the faction (again, possibility to stop early). Final step is to check if kragii leave or not (again, chance of abort).

                                                            \n
                                                            chooseToAvoid :: ( MonadIO m, PersistQueryWrite backend\n                 , BaseBackend backend ~ SqlBackend ) =>\n                 (Key News, KragiiWormsEvent)\n                 -> MaybeT (WriterT [KragiiResults] (ReaderT backend m)) EventRemoval\nchooseToAvoid (_, event) = do\n    faction <- getFaction event\n    (cost, bioLeft) <- calculateNewBio (RawResource 50) (entityVal faction)\n    _ <- destroyCrops faction cost bioLeft\n    removeNews $ PercentileChance 25
                                                            \n

                                                            Loading faction has several step. Id is stored in the event is used to load planet. Planet might or might have an owner faction, depending on if it has been settled. This faction id is used to load faction data. Loading might fail if corresponding record has been removed from database and planet might not be settled at the given time. Any of these cases will result Nothing be returned and whole event resolution being aborted. I’m starting to really like that I don’t have to write separate if statements to take care of these special cases.

                                                            \n
                                                            getFaction :: ( MonadIO m, PersistStoreRead backend\n              , BaseBackend backend ~ SqlBackend ) =>\n              KragiiWormsEvent\n              -> MaybeT (WriterT [KragiiResults] (ReaderT backend m)) (Entity Faction)\ngetFaction event = MaybeT $ do\n    planet <- lift $ get $ kragiiWormsPlanetId event\n    let owner = join $ fmap planetOwnerId planet\n    res <- lift $ mapM getEntity owner\n    return $ join res
                                                            \n

                                                            Amount of biological matter in store is stored in faction information. If it’s zero or less, Nothing is returned as there’s nothing to do really. In other cases, amount of biological matter left is calculated and result returned in form of ( cost, biological matter left ). I’m carrying around the cost, as it’s later needed for reporting how much matter was removed.

                                                            \n
                                                            calculateNewBio :: Monad m =>\n                RawResource Biological -> Faction\n                -> MaybeT (WriterT [KragiiResults] m) ((RawResource Biological), (RawResource Biological))\ncalculateNewBio cost faction = MaybeT $ do\n    let currentBio = factionBiologicals faction\n    return $ if currentBio > 0\n                then Just $ ( cost\n                            , RawResource $ max 0 (currentBio - unRawResource cost))\n                else Nothing
                                                            \n

                                                            destroyCrops updates database with new amount of biological matter in store for the faction and records amount of destruction in CropsDestroyed. tell requires that we have Writer at our disposal and makes recording information nice and easy.

                                                            \n
                                                            destroyCrops :: ( MonadIO m, PersistQueryWrite backend, BaseBackend backend ~ SqlBackend ) =>\n                Entity Faction -> RawResource Biological\n                -> RawResource Biological -> MaybeT (WriterT [KragiiResults] (ReaderT backend m)) ()\ndestroyCrops faction cost bioLeft = MaybeT $ do\n    _ <- lift $ updateWhere [ FactionId ==. entityKey faction ]\n                            [ FactionBiologicals =. unRawResource bioLeft ]\n    tell [ CropsDestroyed cost ]\n    return $ Just ()
                                                            \n

                                                            Final step is to roll a percentile die against given odds and see what happens. In case of Success, we record that worms were removed and value of function will be Just RemoveOriginalEvent. If we didn’t beat the odds, WormsStillPresent gets recorded and value of function is Just KeepOriginalEvent. Return value will then be used later to mark special event handled.

                                                            \n
                                                            removeNews :: ( PersistStoreWrite backend, MonadIO m, BaseBackend backend ~ SqlBackend ) =>\n              PercentileChance -> MaybeT (WriterT [KragiiResults] (ReaderT backend m)) EventRemoval\nremoveNews odds = MaybeT $ do\nres <- liftIO $ roll odds\n    case res of\n        Success -> do\n            _ <- tell [ WormsRemoved ]\n            return $ Just RemoveOriginalEvent\n        Failure -> do\n            _ <- tell [ WormsStillPresent ]\n            return $ Just KeepOriginalEvent
                                                            \n

                                                            So result of this whole matter is:

                                                            \n
                                                            ( [KragiiResults], Maybe EventRemoval )
                                                            \n

                                                            and whole lot of database activity.

                                                            \n

                                                            \n

                                                            Pieces are now in place, time to put things in motion. When handling special events for a faction, first step is to load all unhandled ones and then call handleSpecialEvent for each of them.

                                                            \n
                                                            handleFactionEvents :: (BaseBackend backend ~ SqlBackend\n                       , PersistStoreWrite backend, PersistQueryRead backend\n                       , PersistQueryWrite backend, MonadIO m) =>\n                       Time -> Entity Faction -> ReaderT backend m [Key News]\nhandleFactionEvents date faction = do\n    loadedMessages <- selectList [ NewsFactionId ==.

                                                            \n

                                                            resolveEvent resolves event based on choice user maybe made (this is what we explored earlier in the episode). Depending on the result of resolveEvent, event gets marked to handled and dismissed. In any case, a news article spelling out what happend is created and saved.

                                                            \n
                                                            handleSpecialEvent :: (PersistQueryWrite backend, MonadIO m\n                      , BaseBackend backend ~ SqlBackend) =>\n                      Key Faction -> Time -> (Key News, SpecialNews) -> ReaderT backend m (Key News)\nhandleSpecialEvent fId date (nId, (KragiiWorms event _ choice)) = do\n    (removal, results) <- resolveEvent (nId, event) choice\n    _ <- when (removal /= Just KeepOriginalEvent) $\n                    updateWhere [ NewsId ==. nId ]\n                                [ NewsSpecialEvent =. HandledSpecialEvent\n                                , NewsDismissed =. True ]\n    insert $ report fId date event choice results
                                                            \n

                                                            Result article creation is abstracted by ResultReport type class. It has single function report that takes parameters: database key of the faction the event concerns of, current time, special event that was processed, choice that was made and list of records telling what happened during resolution. It will return News that is ready to be saved into database.

                                                            \n
                                                            class ResultsReport a b c | a -> b, a -> c where\nreport :: Key Faction -> Time -> a -> Maybe b -> [c] -> News

                                                            Instance declaration is pretty long, because there’s many different cases to account for and by definition they’re all pretty verbose. I have included it in its entirity below, as it might be interesting to glance over and see different kinds of combinations that resolution might create.

While this one took quite a bit of work to get working, I’m hoping that the next special event will be a lot easier to implement. Thanks for listening the episode.

                                                            \n

                                                            xsv is a command line program for indexing, slicing, analyzing, splitting and joining CSV files. Commands should be simple, fast and composable:

                                                            \n
                                                              \n
                                                            1. Simple tasks should be easy.
                                                              2. \n
                                                            2. Performance trade offs should be exposed in the CLI interface.
                                                              3. \n
                                                            3. Composition should not come at the expense of performance.
                                                              4. \n
                                                            \n

                                                            We will be using the CSV file provided in the documentation.

                                                            \n

                                                            Hello and welcome to Hacker Public Radio, I’m Edward Miro and for this episode I decided to record on a personal experience I had recently helping a client catch a Craigslist Scam. This will be part two in my series I’m calling “Information Security for Everyone”. As with most of the content I publish in the world of INFOSEC, my goal is to present the information in a way that a majority of people can get value from and anyone can play this for a friend, colleague or family member and make it easy for the non-hackers in our lives to understand. This particular episode shows a powerful way social-engineering can be implemented to steal money from unsuspecting victims and I will break down a few main points and red flags to look out for at the end.

                                                            \n

                                                            A couple weeks ago I was sitting with a client when she asked me offhandedly if I’d ever sent a Moneygram before. I told her I had and ask curiously why she wanted to know. She explained that she was very excited to be adopting a puppy from online and she needed to send $350 USD to the service that ships pets across the country. This immediately caused my hacker-sense to start tingling so I probed a bit more about the transaction.

                                                            \n

                                                            I asked if she had spoken to the seller on the phone, and she said she hadn’t. I said that seemed weird, but she assured me that the seller said it had to do with her religion. I wasn’t aware of any religious prohibitions to speaking on the phone that also allowed using Craigslist, but okay. I told her that that seemed a bit fishy to me. She asserted that she thought it did too at first, but she knew it was legit because she wasn’t sending the money to the seller, it was being sent to a third party pet transportation company that the seller had had contact her. She even showed the website of the company on her cell phone, which to be blunt, to my eyes looked extremely janky. I asked her if we could sit down for a few minutes and take a look at a few details before she sends anyone any money. She reluctantly agreed and really wanted this puppy.

                                                            \n

                                                            The first thing I asked to look at was the emails back and forth from the seller. I checked Google and all other major social media sites for the sellers name. No matches. Couldn’t Google the sellers email address due to the Craigslist email relay system. This in and of itself might be okay, we all use pseudonyms online sometimes and Craigslist is a site you might not wanna use your real name. Fine.

                                                            \n

                                                            She then showed me the email thread with the shipping company.

                                                            \n

                                                            The first strange thing I noticed from the emails was the link to the pet shipping company. The name didn’t match the URL in the link. You’d think a business would be able to get their own name right. I also saw that if you Googled the name given by the shipper, it’s extremely similar to a legitimate pet shipping company and indeed that legit company comes up as the first site found due to Google “fixing” our query. When you go to the link in the email however, the site itself was terrible to my eyes, but not to my client who is not as seasoned as I am at catching scams. I also showed her that the “company” didn’t have any social media presence. At all. No Facebook, Twitter, anything. Also the email address that was contacting her was reallylongcompanyname@outlook.com

                                                            \n

                                                            She also told me she had spoken to the shippers on the phone and I asked if she still had their number. She did, but she told me she couldn’t ever get through when she called them and they’d always have to call her back. I asked for the number and called it on my phone. It was a Google Voice number! Not only that it was set to screening mode. She also told me when he did call her, he was rude and tried to get her to hurry up and send the money. I told her I was 100% confident this was a scam and I advised her to not go through with the deal.

                                                            \n

                                                            At this point she was extremely unhappy, but felt it was still a legitimate transaction because she had pictures sent to her of not only the puppy, but of the puppy in the shipping crate at the shipping company waiting for payment to be shipped. She explained that it’s not like it was a person trying to sell dogs or from a puppy mill. It was a lady giving it away for free and the money was for was the shipping. She just didn’t see why a scammer would go to the trouble of doing that and felt the pictures were authentic. I asked her to save all the images to her device and then showed her a site she could use to do reverse image searches. Before she did it, I asked her if she agreed that if this wasn’t a scam those pictures wouldn’t exist anywhere on the internet. She agreed and each of the pictures was found at least 9 other places online. Her heart sank and she didn’t have any further rebuttals to my concerns. She knew it was a scam and I just saved her from losing at least $350 USD. Not to mention that the scammer would have also asked for more money later for “shots” and “insurance”. Who knows how far they might have gotten.

                                                            \n

                                                            So here are the main red flags:

                                                            • Email address of contact at company using generic email address and not a legit domain

                                                            A few of the tricks used by the scammers in this scam to make it more successful:

                                                            She was very thankful and I told her to be very careful when anyone from online ever asks her to send money. I told her in all likelihood this was probably one person the whole time, hence why the person adopting out the dog “couldn’t talk on the phone”. They were also probably not even in this country as we know many of these scams aren’t. She did say that the shippers English wasn’t good. I also told her to make she shares this experience with all her friends and family. I always feel the best way to handle someone getting caught in a scam is to be on their side and never shame them. We are all susceptible to scams and social engineering and the best way to proceed is to empower them to share what they’ve learned. I also sent her a link to an article on the BBB site about these very types of scams that I’ll also link below. She was shocked how similar her experience was to the ones explained on the article.

                                                            Well, thank you for taking the time to listen to my experience helping a client avoid getting caught in the all too common Craigslist scam. I hope this will help any non-hackers in your life and like I say in all my podcasts, I don’t claim to know all there is to know and love feedback and any opportunities to learn more or collaborate with others in the field. As with most of the research and articles I’ve written in the past, these are geared toward standard users in a business setting and are meant to be a jumping off point for further research and to be a foundation for cyber security 101 level training classes.

                                                            \nI've gotten a lot of great feedback on the Interface Zero play-through and the episode about getting started with RPGs I did with Lostnbronx.\nPeople have told me that one of the biggest blockers to getting started is knowing what to do as GM.

                                                            \nNow, I've read lots of rulebooks and GM guides, and it seems to me that most of them assume you've either played an RPG before, and so you've seen an example of a Game Master at play, or you've seen one on Youtube or Twitch. It's a safe assumption, but it's easy to forget all of those great examples under pressure.\nSo in this episode, Lostnbronx and I are going to provide you with some clear and direct instructions on what exactly a GM does.\n

                                                            \nThe short version is this:

                                                            \n

                                                            1. \nTell the players where they are and what they see around them.\n

                                                            2. \nListen to the players when they tell you what they want to do.\n

                                                            3. \nTell the players the outcome, based on your privileged knowledge of the game world or on a roll of the dice, of their actions.\n

                                                            \n

                                                            \nYou loop over that sequence, and you're game mastering!\n

                                                            \nBut that makes for a short episode, and anyway, there are details about the process that we can talk about to make you feel more comfortable with the prospect of deciphering a game world with your friends.\n

                                                            \nTo that end, Lostnbronx and I have started a website dedicated to gaming! You should check it out, subscribe to our feed. We discuss everything game-related there, plus a little tech and all manner of topics of interest to geeks.\n

                                                            \n\n

                                                            Lostnbronx

                                                            \n

                                                            \nRight off the bat, it's important to understand that every GM is different. No two styles of running a game match completely, nor should they. And while there's no one correct way to run a game, there are plenty of ways to do it poorly. The GM wears many hats, but in my opinion, the most important job is to make sure that everyone has a good time. Your players are giving you an evening out of their lives. Next week they'll probably give you another. It's your job to make sure that time isn't wasted.\n

                                                            \nBy definition, games, even role-playing games, are a form of entertainment -- like reading a book, watching a movie, or enjoying the circus. When you go to that, the GM is the ringmaster, presenting the show; while the players are both the audience, and the main attraction. The GM controls the world, the people, the monsters, the history, even the weather. The GM controls everything, in fact...except for the player characters. A game master presents the situation, but it's the players who decide what to do with that information.\n

                                                            \nNow, this is all pretty vague, and describing RPG's is far less informative than playing them. Considering this is a podcast, I encourage you to go back and listen to Klaatu's aforementioned \"Interface Zero\" episodes. These are excellent examples of actual game play. If you're having a hard time imagining how RPG's are presented and experienced, you'll appreciate those shows.\n

                                                            \nNow then, almost all games are divided into genre types: sword and sorcery; space opera; spies; super-heroes; and pretty much everything else. And I mean everything! If there's a genre of fiction and storytelling that you enjoy, chances are there's a game or game setting for it somewhere. The most popular style of RPG's out there are fantasy. Think \"Lord of the Rings\". Think \"Harry Potter\". Think of anything, in fact, because all of it is possible.\n

                                                            \nA staple of the high fantasy genre of gaming is the dungeon. Now, that term has two meanings in this sort of game: first, the usual meaning, of what amounts to the basement of a castle, with jails, interrogation rooms, storage rooms, and more. The other meaning refers specifically to a type of adventuring environment. Both of these are usually found underground, but an adventuring dungeon may have nothing to do with any castle. It might be a lost crypt, a cave system, an abandoned gold mine, or the lair of some dreaded beast that's been terrorizing the countryside. In the dungeon might be enemies, monsters, and treasure protected by deadly traps. Magic abounds. There might be puzzles, dark secrets, or a kidnapped prince to rescue.\n

                                                            \nAs a new GM, you can start off any way you want, but in my experience, the best way to get used to how the game works, and how the whole process of providing an evening's entertainment to your friends or family works in this context, is to create a dungeon and run your players through it.\n

                                                            \nDungeons generally require set-up time; that is to say, you have to design it in advance. Now, Klaatu and I are currently working on ways to ease that burden, with the ultimate goal of eliminating the pre-work entirely. But for now, let's talk about the traditional way to approach all this. What follows is a step-by-step process, but understand, it's only one of an infinite possible number of them.\n

                                                            \nSTEP 01 -- CREATE THE COUNTRYSIDE\nSome GM's say creating the world is the first step. Some say creating the godly pantheons of the world is the first. Some say it's the history, or the fantasy races. They're not wrong, but trust me, when you're just starting out, none of that stuff matters. In this example, you'll be running the players through a dungeon. That dungeon is out in the country, within the middle of a large forest.\n

                                                            \nNow, it will make the beginning and end of the adventure easier if you have a small village nearby where the player characters all live. We'll call it Forestdale for the lack of anything better. In Forestdale, there's an inn or tavern. This is where people get together, tell tall tales, and become inspired to go adventuring, so let's give it a name as well: \"The Prancing Unicorn\". That's home base. Every player character knows this place, and everyone in it knows them.\n

                                                            \nOne of the stories being swapped at \"The Unicorn\" lately is about a tribe of dangerous creatures living in an underground lair somewhere within the forest. They are led by an evil wizard, or so the tales go. They have been attacking farmers and merchants who travel through the roads and foot paths of the woods in order to sell their goods in Forestdale. One of the merchants says he saw them travel down the Western path near the Old Bridge. Something must be done, but who would be brave or foolhardy enough to even try?\n

                                                            \nAnd that's all you need to create for the world right now. Remember, this stuff is new; no one needs large amounts of detail just yet, least of all you. You'll have enough to juggle.\n

                                                            \n\n\nSTEP 02 -- CREATE THE DUNGEON FLOOR PLAN\nOne of the rumors to be heard at \"The Prancing Unicorn\" is that there's an underground cave system or labyrinth somewhere in the forest. Some say it's a myth, others say their cousin's uncle's sister's best friend came across it once. Either way, its existence is shrouded in mystery, and people are said to go in, but not always come out.\n

                                                            \nThis is your first dungeon. You don't want to do more work than you need to. Let's make this dungeon a single level. Later, you can add a secret panel somewhere that can reveal a set of stairs down to a second level (and from there, a third, fourth, tenth, or more). Right now, it's one level, hidden below the forest. It's dark, it's dangerous. It's plenty.\n

                                                            \nPutting a dungeon together can be difficult, but it doesn't have to be. The traditional way to create one of these is to use graph or hex paper and draw out the floor map. Each square of the graph paper is equal to ten feet, or, say, three meters. You make note of all rooms, caves, doors, hallways, stairs up or down, floor traps, hidden doors, and anything else you want in there. Be sure to put a set of stone stairs that lead from the forest above, down to this dank and gloomy dungeon.\n

                                                            \nThere are no standard symbols for the different things on the map, despite what anyone might tell you, but for now, let's turn the paper landscape style, and at the top of the page, now held that way, outline one square of the graph paper with a pencil. Inside the square, draw three or four small lines at an angle. This will represent a set of stairs. Next to the stairs, write the letter \"U\". This is the way to get to the forest above. Granted, it's how the player characters will come down here to begin with, but once they are here, they have to go up to leave, hence the \"U\". If that's confusing, you can write, \"To The Forest Above\", next to this square, maybe with a little arrow. You can write anything you want, but this is how the player characters will get in and out of your dungeon.\n

                                                            \n\n

                                                            \nWe're going to draw the floor plan from the top of the page down. The entire dungeon map will be on this one side of the paper. In the corner, draw an arrow pointing up, and put a letter \"N\" there. That's North. We'll be using compass directions from now on. Granted that when underground, it's hard to get your bearings without a compass, but for this first dungeon, we won't worry about that. North, South, East, West. It makes life easy.\n

                                                            \nOn the bottom of the page, to the South, draw a box in the middle of the page that's ten by ten squares in size. This is where the dungeon tunnels all will be leading, and where we'll have the biggest fight of the adventure. We're setting that up now, so we always know where we're heading. Now go back to the stairs at the top of the page.\n

                                                            \nDraw a long line from the lower edge of the stairs going West. Stop the line a square or two from the edge of the paper. Now do the same thing going East. Next, move down one square, and draw another line parallel to both of these, going entirely from one side of the page to the other, East to West. You've just created a place for the players to explore, so imagine it for a moment: they come down some broken, forgotten stairs. Let's say they travel at least a hundred feet down, tripping over tree roots and walking through cobwebs, until the stairs deposit them in the middle of a dark tunnel, ten feet wide. It stretches to either side, running East and West out of sight (you know that it goes hundreds of feet in both directions, but you'll let them discover that for themselves). They listen, and can hear nothing but the scurrying of unseen vermin. At least, they hope that's what it is. Not a bad start.\n

                                                            \n\n

                                                            \nAlong this hallway, you'll draw little rectangles, like black bars, on random squares along the Southern side of the tunnel. Not too many, just a few here and there, with generous space in between. These are heavy wooden doors. Some may be locked. That's your choice. If they are, put a little symbol near them. It could be as simple as the letter \"L\", so let's go with that. Now you know where the all doors are in this particular tunnel, and you know which of them will be a challenge for the player characters to open.\n

                                                            \nThis is just the first tunnel of a larger complex. This complex can be as big or as small as you'd like. Let's say it's moderately sized. Before we draw more tunnels, let's draw the rooms behind those doors. This will tell us how much map space we'll have for further tunnels. Some GM's like to draw all the tunnels first, and then fit in the rooms. You can do it however way you want later on; right now, let's just use this method. Pick a door. Draw a box behind it, three or four squares in size. That's the room. Do the same behind the other doors. Make the rooms different shapes and sizes, but not too big. Let the big room at the bottom be the star. When you're done, you have a huge tunnel, with several mysterious doors, behind which are some good-sized rooms.\n

                                                            \nOn the part of the tunnel that ends on the West side, draw a connecting tunnel South for five squares, and then turn the direction back to the East. Draw this tunnel going that way for ten squares. Put a door or two along here, and draw some rooms for them. Turn the tunnel South again, and go five or six squares, and turn it East again for four squares. Draw a door and room. Maybe it's locked, maybe not. Continue with this meandering, jagged floor plan, wandering East and then West, but always moving South. Add occasional doors and rooms as you go, until your tunnel finally ends on the Western side of the large ten by ten square room at the bottom of the page. Draw a door to get in there.\n

                                                            \n\n

                                                            \nNow go back up to the long tunnel at the top, and repeat this whole process on the Eastern side, eventually bringing that part of the tunnel to the Eastern edge of the big room at the bottom. Put a door there.\n

                                                            \n\n

                                                            \nNow, number your rooms on the map, starting at at the top, and working your way down, until you've marked each one. Room numbers are essential, because you'll be keeping track of each one.\n

                                                            \n\n

                                                            \nThe floor plan to your first dungeon is complete. Now you need to put interesting things in it.\n

                                                            \n\nSTEP 03 -- POPULATE YOUR DUNGEON\nOkay, on a separate piece of paper, list the rooms of your dungeon. Start at #1, and go down. Beside the room number, you put in a brief description, along with any monsters, treasure, or other points of interest. You'll be consulting this list throughout the game, so write down everything you need to know, in order to minimize the amount of time you'll inevitably have your nose in the rulebook while playing. Monster statistics, including their weapons, and and the damage they do, should all be on this list, though there are ways to simplify the process, once of which I'll go into in a moment.\n

                                                            \n\n

                                                            \nWhen putting creatures and things into your dungeon, the first thing to remember is to not overload it. Each room does not need a monster. Not every room needs treasure. It might be helpful to think in terms of what you'd like to see in the dungeon as a whole. Remember the stories of evil creatures, and possibly a wizard, which you heard at \"The Dancing Unicorn\"? We'll use that as our springboard. This is a starting dungeon, not just for you, but also for the player characters. Starting dungeons mean low-level monsters, so let's go with goblins.\n

                                                            \nGoblins are generally quite impressed with magic, so we're going to assume a wizard of dubious character has bullied a small tribe of them into being his thugs. They've been waylaying passing merchants and farmers, stealing their wares, and carrying off food (along with the occasional peasant worker, as goblins love the taste of human flesh). Stupid, but dreadful creatures, they have displayed a level of tactical organization that's not normal for them. This, of course, is because the wizard's in charge. Look up the statistics for goblins, and understand what they're like. For this adventure, we're not going to worry about goblin captains, or goblin chiefs, both of which are tougher than your average goblin. No, all the creatures for this adventure have the same statistics. Don't drive yourself crazy writing them down, over and over. Write them once at the bottom of the room description page, and every time the player characters run into a goblin, consult them.\n

                                                            \nLet's say there are a total of fifteen goblins in this dungeon. They won't all be together; the player characters will encounter a few of them here and there, in various rooms, or maybe ust wandering the tunnels. The rooms themselves will have the spoils of all their raids, including barrels of wine, hams and sides of beef; furs, and a few copper, silver, and gold coins. If there's wine in one of the rooms, maybe the goblins there are drunk, fighting at a penalty to hit and damage. And remember, not all rooms need things in them. Maybe this was once a temple, and there's just broken furniture, and rotting religious robes in some of the rooms. In one, there might also be a tapestry against the wall, depicting a miracle of whatever god this place was once dedicated to. What you might not tell the player characters up front is that the tapestry could fetch a fair amount of gold coins in the market back in Forestdale. Too big to carry while exploring the dungeon, such a thing could always be rolled up and fetched on their way out. Not all treasure is found in wooden chests.\n

                                                            \nThen again, a lot of it is, so why not put one in the big room to the South? Of course, you have to defeat the evil wizard and his goblin cohorts, wh are hanging out in there. As a rule of thumb, you might want to sprinkle half the goblins throughout the dungeon, leaving the other half here, for the final fight. Stealth matters. Approaching the big room noisily, and kicking open one of the doors, is not stealthy. The player characters might be able to catch the wizard and his minions off-guard, if they move quietly.\n

                                                            \nIn order to be a credible threat to the player characters, this wizard should be of a slightly higher level, say 2nd or 3rd. He'll have some aggressive spells, and he'll have his goblins handy. You'll roll up the wizard the same way the players rolled up their characters, only you'll make him more experienced, and with more spells at his command. Maybe he even has a magic item of some sort. Should the players defeat this guy, this magic item will be part of the treasure; until then, it's something the wizard will use against them. Don't make it too tough. Maybe don't make it tough at all: a +1 Ring of Protection, maybe. Or perhaps, a +1 dagger. That might not sound like much, but it's more than the player character's have when they start.\n

                                                            \nNot enough excitement, maybe? Just add in a couple of giant rats in one of the rooms. Maybe some large spiders in another. Don't forget to put their statistics down in the room description. Judging how tough or easy a dungeon needs to be comes with experience. My suggestion is to err on the side of toughness, to put more challenges in there than maybe you feel comfortable with. If the player characters are looking depleted and injured, you can say the room is empty, instead of filled with spiders. Also, it doesn't hurt at all to remind the players now and then that it's okay to retreat. They can always come back another day when they're rested, and have made plans based on the knowledge they gained the first time around. It sets up a grudge match...the heroes vs. the evil wizard and his goblin hoard. You, as the GM, just repopulate the goblins, move them around a bit, so they're not all in the same rooms as before (though the big room should still be for the final fight), and //voila//! You've just provided your players with two night's worth of entertainment, for the effort of only one.\n

                                                            \nAnd there you have it: a stocked dungeon that dovetails into the local lore of the countryside, ready for your players to explore.\n

                                                            \n\n\nSTEP 04 -- ROLLING UP CHARACTERS\nSome GM's will want a whole night just for this process. Others will just have the players arrive at the game with their characters ready to go, especially if they are experienced with the game. I won't go over the character creation process here, because each game is different, and some are VERY different. I mention this now, though, because the players need characters, and creating them comes before the adventure starts. If the game is as new to them as it is to you, take that whole night to help them create their characters. It's fun all on its own, and it allow's everyone to be familiar with the other characters -- something vital to party survival.\n

                                                            \nI'm not going to go into detail about the process of rolling up characters, because, like you, Klaatu and I have dedicated an evening just to this process. In a previous episode in this mini-series, the two of us created a character from the ground up, so you can hear what's involved, and how you might want to approach the process with your own players.\n

                                                            \n

                                                            Klaatu

                                                            \n

                                                            \nIf designing your own custom dungeon seems intimidating to you, there is another way. And it's a time-honoured, legitimate way to play, and it's quite often the way I play: you go find an adventure that someone else has already written.\n

                                                            \nAn adventure is the scenario you and your players experience when you sit down at the table to play. It's arguably the *game* (the rulebooks are the game engine, or the mechanics). Wizards of the Coast, Paizo, Catalyst, Kobold Press, Frog God, and many others publish adventures (sometimes called \"modules\", \"scenarios\", or \"adventure paths\") written by professional game designers. Published adventures provide the story framework for your game.\n

                                                            \nNot all systems publish adventures, though, or you may choose not to use one. If that's the case, spend some time developing a story. Writing a good game is part science, part craft, and part magic, but if you and your players are up to the challenge, then running blindly through a story that's mostly being created spontaneously on the spot can be a lot of fun. If that sounds overwhelming, though, get a published adventure!\n

                                                            \nQuick tip: Free, small, or introductory adventures are often available from https://drivethrurpg.com, https://dmsguild.com, and https://www.opengamingstore.com\n

                                                            \nMany adventures have text blocks that provide you with introductory text for each part of the game, they explain clearly what the goal of the players is during that segment, and give you guidance on what players will find in the area and how those discoveries lead to the next plot point.\n

                                                            \nBroadly speaking, there are two types of published adventures: there are \"one-shots\" and there are \"modules\" or \"adventure paths\".\n

                                                            \nA one-shot adventure is analogous to a quest in a video game: it's a single, clearly-defined task with a very obvious and immediate result; for example, goblins are terrorizing the hapless citizens of the local village, so go to their cave and clear it out: if you do, you'll relieve the villagers of the horrors, and you get to keep any gold or weapons you find.\n

                                                            \nThe advantage is that it's designed to be a quick, one-time game session, so it's perfect for playing with friends you only see once in a while, or with someone who's never played before and just isn't sure if it's something they want to commit to. Don't be fooled by the page count of these small adventures: it may only be 5 to 10 pages long, sometimes less, but you'll be surprised at how long players can spend exploring a boundless world existing only in their imagination.\n

                                                            \nAdventure paths or modules or campaigns are bigger stories with\nloftier goals. You can think of them as lots of little one-shots\nstrung together so that once players accomplish all the tasks and\nsolve all the mysteries over the course of 200 pages, they have a\nfinal showdown with some Big Bad, and win themselves a place in the\nlegends of the game world. It's an epic poem instead of a short\nstory. It feels grander, it feels important. The losses along the way\nare more profound, and the victories sweeter. These campaigns take\nmonths to play through and usually expect a gaming group to meet\nweekly or fortnightly or at least monthtly to work their way through\nthe tale.\n

                                                            \nI should mention one more kind of book you might stumble across, and\nthose are source books. I mention this because I've had friends go and\nbuy books more or less blindly, and then they bring them back home\ndisappointed that instead of a book of lore about dark elves, they\nbought an adventure set in the underdark. Or the other way round: they\nwanted an adventure and ended up with a rule book.\n

                                                            \nThis happens with the bigger systems that produce a lot of media, like\n{D&D, Shadowrun, Pathfinder, Warhammer}, so get clarity on what you're\nbuying before you make a purchase. If you come across a cool ShadowRun\nbook called RUN FASTER expecting a campaign to run with your friends,\nyou'll be surprised to find that you've purchased a source book full\nof metatypes, expanded rules, and alternate character creation\nmethods: sort of a Shadowrun Core Rulebook part 2. Same goes for, say,\nVolo's Guide with D&D, or Ultimate Campaign in Pathfinder. It can be\noverwhelming and they're not aways labelled clearly (or if they are,\nthe label gets lost in the word cloud of RPG jargon that you're not\nused to yet), so do a little research first.\n

                                                            \nI've played through dungeons that a GM created over his lunch break, and I've played through adventures written by clever game designers, and I can confidently say that they're both great ways to RPG. But as a GM, if you feel overwhelmed by the idea of designing a dungeon, a published adventure is a great way to start. Aside from reading a chapter ahead before each game night, all the prep work is done for you, and there's very little thinking required.\n

                                                            \nAnother part of being GM is deciding when a die roll is necessary. Die rolls represent the chance of success or failure when a specific action is taken, but the confusing thing is: if you think hard enough about anything in the world you can find a chance of success or failure. As a GM, it's up to you to decide what's \"important\" enough for a roll. Strictly speaking, that's determined by the rules. The rules told you what requires a roll, and you're expected to know the rules well enough to make the call.\n

                                                            \nIn practise, however, you have a lot of stuff to track in you head, and remembering what requires a die roll, or deciding to request a die roll even though it may not be strictly required, can feel overwhelming for a new GM.\n

                                                            \nGood news: Players intuitively know when to roll dice. A player knows their character's skills (because they built the character and wrote it down on their character sheet), so sometimes the actions they choose to take are chosen because it falls within a category of a skill they happen to have. A thief probably wouldn't ever think to *look* for hidden door if the thief were a fighter (who would more likely think to pound on the wall rather than to slyly look for a hidden door). So if your player reaches for dice, let them roll because they're probably right.\n

                                                            \nI'm sure it's possible to take it too far, but people like to roll dice. It's part of the fun of an RPG, the uncertainty of subjecting yourself to the whims of fate. So when in doubt, either make your players roll dice, or roll dice yourself. I use dice rolls to help me decide everything from NPC reactions to weather conditions. It's usually safe to default to rolling.\n

                                                            \nWorst case scenario is that die are only picked up for fights and a literal interpretation of skills: and that works because those are the rules as written.\n

                                                            Klaatu

                                                            \n

                                                            \nPlayers drive the story. In video game or movie terminology, they control the \"camera\". When players are exploring or investigating, let them ask questions or take actions (\"I look in the closet\"), and answer them as you see fit (\"You open the closest and see an array of fine garments.\")\n

                                                            \n\"I'll move the clothes aside and examine the walls, and the floor. I'm looking for trap doors or hidden compartments, or anything suspicious.\"\n

                                                            \nAnd so on. Players can choose to investigate and explore for as much as they want. That's the beauty of a pen-and-paper RPG: the world is infinite. That said, you're the GM and you owe it to your players to keep the game moving. You don't to let your players spend 3 real hours searching a room that, in the end, has no bearing upon the plot whatsoever. That can be a delicate matter, because the nature of the game means that you know things that the other players don't, meaning much of the puzzle for players is what they don't know.\n

                                                            \nUsually I let players explore a space on their own until I feel that they've explored the obvious parts of it, and then I remind them where the exits are, or I remind them how many other rooms there are to explore, or some subtle clue to say, without saying, that they've secured an area.\n

                                                            \nIf players are especially suspicious of something, though, you certainly have the power to generate a subplot, and often times you should do that. It's fun for you and rewarding to players. For instance, if a player is convinced that there's a secret panel in a closet and spends a lot of time investigating, then you might decide that there IS a secret panel in the closet, and then roll on a random table to determine what could possible inside that compartment. Or you could leave the compartment empty, thereby creating a story hook to return to later...what used to be in that compartment? who took it, and why? What were the implications?\n

                                                            \nKeeping the gaming moving is an inexact, unscientific process, but usually it comes pretty naturally. When you start to get bored of the players exploring, you can bet that they're probably getting bored too, and that's when you know to urge them forward. If all else fails, you can always have something lure them from one space to another: a mysterious sound, an oncoming threat, or a supernatural or divine instinct.\n

                                                            I have been doing series about web programming in Haskell and realized that I might have skipped over some very basic details. Better later than never, I’ll go over some of them briefly (data types and database actions). Hopefully things will make more sense after this (like with my friend, whose last programming course was programming 101 and they said afterwards that now all that 3d and game programming is suddenly making sense).

                                                            \n

                                                            Data types

                                                            \n

                                                            Data here has nothing to do with databases (yet). This is how you can declare your own data types in Haskell. They’re declared with keyword data followed with type name, equals sign and one or more value constructors. Type name and value constructors have to start with uppercase letter.

                                                            \n

                                                            Simplest type is following:

                                                            \n
                                                            data Simple = One
                                                            \n

                                                            This declares a type called Simple that has single possible value: One.

                                                            \n

                                                            More interesting type is shown below. Colour has three possible values: Red, Green and Blue.

                                                            \n
                                                            data Colour =\n    Red\n    | Green\n    | Blue
                                                            \n

                                                            It’s possible to have parameters in value constructor. Following is Payment type that could be used to indicate how payment was done. In case of Cash amount is stored. In case of IOU free text is recorded.

                                                            \n
                                                            data Payment =\n    Cash Double\n    | IOU Text
                                                            \n

                                                            Fictional usage of the Payment is shown below. Function paymentExplanation takes a Payment as parameter and returns Text describing the payment. In case of cash payment, brief explanation of how much was paid is returned. In case of IOU slip the function returns explanation stored in IOU value.

                                                            \n

                                                            paymentExplanation :: Payment -> Text part is type declaration. It states that paymentExplanation takes argument of type Payment and returns result as Text.

                                                            \n
                                                            paymentExplanation :: Payment -> Text\npaymentExplanation payment =\n    case payment of\n        Cash amount ->\n            "Cash payment of " <> (show amount) <> " euros"\n        IOU explanation ->\n            explanation
                                                            \n

                                                            Parameters don’t have to be hard coded in the type definition. Parametrized types allows creating more general code. Maybe is very useful data type that is often used for data that might or might not be present. It can have two values: Nothing indicating that there isn’t value and Just a indicating that value is present.

                                                            \n
                                                            data Maybe a =\n    Nothing\n    | Just a
                                                            \n

                                                            a is type parameter that is filled in when declaring type. Below is a function that takes Maybe Payment as a parameter and if value of payment parameter is Just returns explanation of it (reusing the function we declared earlier). In case of Nothing "No payment to handle" is returned.

                                                            \n
                                                            invoice :: Maybe Payment -> Text\ninvoice payment =\n    case payment of\n        Just x ->\n            paymentExplanation x\n        Nothing ->\n            "No payment to handle"
                                                            \n

                                                            Alternatively one can omit case expression as shown below and write different value constructors directly as parameters. In both cases, compiler will check that programmer has covered all cases and emit a warning if that’s not the case.

                                                            \n
                                                            invoice :: Maybe Payment -> Text\ninvoice (Just payment) =\n    paymentExplanation payment\n\ninvoice Nothing =\n    "No payment to handle"
                                                            \n

                                                            Having several parameters gets soon unwieldy, so lets introduce records. With them, fields have names that can be used when referring to them (either when creating or when accessing the data). Below is Person record with two fields. personName is of type Text and personAge of type Age (that we’ll define in the next step).

                                                            \n
                                                            data Person = Person\n    { personName :: Text\n    , personAge :: Age\n    }
                                                            \n

                                                            To access data in a record, just use field as a function (there’s a bug, I’m turning 40, this month (today even, to be specific, didn’t realize this until I was about to upload the episode), but forgot such a minor detail when recording the episode):

                                                            \n
                                                            me = Person { personName = "Tuukka", personAge = 37 }\nmyAge = personAge me\nmyName = personName me
                                                            \n

                                                            New type is special type of record that can has only one field. It is often used to make sure one doesn’t mix similar data types (shoe size and age can both be Ints and thus mixed if programmer isn’t being careful). Compiler will optimize new types away during compilation, after checking that they’re being used correctly. This offers a tiny performance boost and makes sure one doesn’t accidentally mix different things that happen to look similar.

                                                            \n
                                                            newtype Age = { getAge :: Int }
                                                            \n

                                                            One can instruct compiler to derive some common functions for the data types. There are quite many of these, but the most common ones I’m using are Show (for turning data into text), Read (turning text into data) and Eq (comparing equality).

                                                            \n
                                                            data Payment =\n    Cash Double\n    | IOU Text\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Database

                                                            \n

                                                            In case of Yesod and Persistent, database structure is defined in models file that usually located in config directory. It is read during compile time and used to generate data types that match the database. When the program starts up, it can check structure of the database and update it to match the models file, if migrations are turned on. While this is handy for development, I wouldn’t dare to use it for production data.

                                                            \n

                                                            Following definitions are lifted from the models file of the game I’m working.

                                                            \n
                                                            StarSystem\n    name Text\n    coordX Int\n    coordY Int\n    deriving Show Read Eq
                                                            \n

                                                            This defines a table star_system with columns id, name, coord_x, coord_y. All columns have NOT NULL constraint on them. It also defines record StarSystem with fields starSystemName, starSystemCoordX and starSystemCoordY.

                                                            \n
                                                            Star\n    name Text\n    starSystemId StarSystemId\n    spectralType SpectralType\n    luminosityClass LuminosityClass\n    deriving Show Read Eq
                                                            \n

                                                            This works in the same way and defines table star and record Star. New here is column star_system_id that has foreign key constraint linking it to star_system table. Star record has field starStarSystemId (silly name, I know, but that’s how the generated names go), which has type Key StarSystem.

                                                            \n

                                                            spectral_type and luminosity_class columns in the database are textual (I think VARCHAR), but in the code they’re represented with SpectralType and LuminosityClass data types. In order this to work, we have to define them as normal data types and use derivePersistField that generates extra code needed to store them as text in database:

                                                            \n
                                                            data SpectralType = O | B | A | F | G | K | M | L | T\n    deriving (Show, Read, Eq)\nderivePersistField "SpectralType"\n\ndata LuminosityClass = Iap | Ia | Iab | Ib | II | III | IV | V | VI | VII\n    deriving (Show, Read, Eq)\nderivePersistField "LuminosityClass"
                                                            \n

                                                            Final piece in the example is Planet:

                                                            \n
                                                            Planet\n    name Text\n    position Int\n    starSystemId StarSystemId\n    ownerId FactionId Maybe\n    gravity Double\n    SystemPosition starSystemId position\n    deriving Show Read Eq
                                                            \n

                                                            This introduces two new things: ownerId FactionId Maybe removes NOT NULL constraint for this column in the database, allowing us to omit storing a value there. It also changes type of planetOwnerId into Maybe (Key Faction). Thus, planet might or might not have an owner, but if it has, database ensures that the link between planet and faction (not shown here) is always valid.

                                                            \n

                                                            Second new thing is SystemPosition starSystemId position that creates unique index on columns star_system_id and position. Now only one planet can exists on any given position in a star system.

                                                            \n

                                                            Database isn’t any good, if we can’t insert any data into it. We can do that with a function shown below, that create a solar system with a single planet:

                                                            \n
                                                            createSolarSystem = do\n    systemId <- insert $ StarSystem "Solar system" 0 0\n    starId <- insert $ Star "Sol" systemId G V\n    planetId <- insert $ Planet "Terra" 3 systemId Nothing 1.0\n    return (systemId, starId, planetId)
                                                            \n

                                                            To use the function, we have to use runDB function that handles the database transaction:

                                                            \n
                                                            res <- runDB createSolarSystem
                                                            \n

                                                            There are various ways of loading data from database. For loading a list of them, selectList is used. Here we’re loading all planets that have gravity exactly 1.0 and ordering results by the primary key in ascending order:

                                                            \n
                                                            planets <- runDB $ selectList [ PlanetGravity ==. 1.0 ] [ Asc PlanetId ]
                                                            \n

                                                            Loading by primary key is done with get. It returns Maybe, because data might or might be present that match the primary key. Programmer then has to account both cases when handling the result:

                                                            \n
                                                            planet <- runDB $ get planetId
                                                            \n

                                                            Updating a specific row is done with update function (updateWhere is for multiple rows):

                                                            _ <- runDB $ update planetId [ PlanetName =. "Earth" ]
                                                            \n

                                                            Finally, sometimes it’s nice to be able to delete the data:

                                                            \n
                                                            _ <- runDB $ delete planetId\n_ <- runDB $ deleteWhere [ PlanetGravity >. 2 ]
                                                            \n

                                                            While persistent is relatively easy to use after you get used to it, it lacks ability to do joins. In such cases one can use library called Esqueleto, that is more powerful and has somewhat more complex API.

                                                            \n

                                                            \n

                                                            Because functions are values in Haskell, nothing prevents storing them in data types:

                                                            \n
                                                            data Handler =\n    Simple (Int -> Boolean)\n    | Complex (Int -> Int -> Int)
                                                            \n

                                                            Handler type has two possible values: Simple has a function that turns Int into Boolean (for example odd used to check if given number is odd) and Complex that takes two values of type Int and returns Int (basic arithmetic for example, adding and subtracting).

                                                            \n

                                                            Hopefully this helps you to follow along as I work on the game.

                                                            Since my daughter has been learning a bit of guitar in the last several months, I've actually gotten my old electric guitar and amplifier back out again after many years in the closet. The amp is a Peavey Bandit 65, which was a an affordable solid-state workhorse kind of amp back in the mid-80s and I've had it since it was new. In this episode I talk through the process of removing the brains of the amp and cleaning the potentiometers to try to get rid of some of the static that's happening when I turn the knobs. I also discover belatedly that the reason I was not getting any distortion when I turned the saturation up was that the amp was stuck on the clean channel — shows how long it's been since I used the amp, I kind of forgot how the thing works!

                                                            \nThe toolchain for encoding and decoding DjVu is \ndjvulibre\n

                                                            Creating a djvu file

                                                            \n\n

                                                            \nThe tool you use to convert something to the .djvu format depends on your requirements. If you're converting a basic, black-and-white document, then cjb2 (part of the djvulibre distribution) works:\n

                                                            \n\n

                                                            \n\n

                                                            \nIf you want to convert something more complex, then use c44 (also a part of the djvulibre distribution):\n

                                                            \n\n
                                                            \n$ c44 -dpi 300 bar.jpg bar.djvu\n$ ls\nbar.jpg\nbar.djvu\n
                                                            \n\n

                                                            \nTo put both of these files in a single DjVu container:\n

                                                            \n\n

                                                            \nYou can add bookmarks, too.\nOpen a text file called book.marks (or any name you prefer) and enter:\n

                                                            \n\n

                                                            \n(bookmarks\n(\"Foo\" \"#1\")\n(\"Bar\" \"#2\")\n)\n
                                                            \n\n

                                                            \nAnd then apply it to your DjVu file:\n

                                                            \n\n

                                                            \n\n

                                                            \nThere's more you can do with DjVu, but this has been an overview of how I use it.\n

                                                            Intro

                                                            \n

                                                            In episode hpr2748 Writing Web Game in Haskell - Special events, I talked about how to add special events in the game. One drawback with the system presented there was that the kragii worms might attack planet that already had kragii worms present. This time we’ll look into how to prevent this. As a nice bonus, we also come up with system that can be used to record when a planet has particularly good harvest season.

                                                            \n

                                                            Data types and Database

                                                            \n

                                                            We need a way to represent different kinds of statuses that a planet might have. These will include things like on going kragii attack or a particularly good harvest season. And since these are will be stored in database, we are also going to use derivePersistField to generate code needed for that.

                                                            \n
                                                            data PlanetaryStatus =\n    GoodHarvest\n    | PoorHarvest\n    | GoodMechanicals\n    | PoorMechanicals\n    | GoodChemicals\n    | PoorChemicals\n    | KragiiAttack\n\nderivePersistField "PlanetaryStatus"
                                                            \n

                                                            We could have recorded statuses as strings, but declaring a separate data type means that compiler can catch typos for us. It also makes code easier to read as PlanetaryStatus is much more informative than String or Text.

                                                            \n

                                                            For database, we use following definition shown below in models file. It creates database table planet_status and respective Haskell data type PlanetStatus. There will be one row in database for each status that a planet has. I could have stored all statuses in a list and store that in database, effectively having one row for any planet. Now there’s one row for any planet + status combination. Choice wasn’t really based on any deep analysis, but merely a gut feeling that this feels like a good idea.

                                                            \n
                                                            PlanetStatus json\n    planetId PlanetId\n    status PlanetaryStatus\n    expiration Int Maybe\n    deriving Show Read Eq
                                                            \n

                                                            expiration column doesn’t have NOT NULL constraint like all other columns in the table. This is reflected in PlanetStatus record where data type of planetStatusExpiration is Maybe Int instead of Int. So some statuses will have expiration time, while others might not. I originally chose to represent time as Int instead of own data type, but I have been recently wondering if that was really a good decision.

                                                            \n

                                                            Kragii attack, redux

                                                            \n

                                                            Code that does actual database query looks pretty scary on a first glance and it’s rather long. First part of the code is there to query database and join several tables into the query. Second part of the code deals with counting and grouping data and eventually returning [Entity Planet] data that contains all planets that match the criteria.

                                                            \n
                                                            -- | Load planets that are kragii attack candidates\nkragiiTargetPlanets :: (MonadIO m, BackendCompatible SqlBackend backend\n                           , PersistQueryRead backend, PersistUniqueRead backend) =>\n                           Int -> Int -> Key Faction -> ReaderT backend m [Entity Planet]\nkragiiTargetPlanets pop farms fId = do\n    planets <- E.select $\n        E.from $ (planet `E.LeftOuterJoin` population `E.LeftOuterJoin` building `E.LeftOuterJoin` status) -> do\n            E.on (status E.?.

PlanetStatusStatus))\n            E.orderBy [ E.asc (planet E.^. PlanetId) ]\n            return (planet, population, building)\n    let grouped = groupBy ((a, _, _) (b, _, _) -> entityKey a == entityKey b) planets\n    let counted = catMaybes $ fmap farmAndPopCount grouped\n    let filtered = filter ((_, p, f) ->\n                                p >= pop\n                                || f >= farms) counted\n    let mapped = fmap ((ent, _, _) -> ent) filtered\n    return mapped
                                                            \n

                                                            In any case, when we’re querying for possible kragii attack candidates, the query selects all planets that are owned by a given faction and have population of at least 10 (left outer join to planet_population table), have at least 5 farming complex (left outer join to building table) and don’t have on going kragii attack (left outer join to planet_status table). This is encapsulated in kragiiTargetPlanets 10 5 function in the kragiiAttack function shown below.

                                                            \n

                                                            Rest of the code deals with selecting a random planet from candidates, inserting a new planet_status row to record that kragii are attacking the planet and creating special event so player is informed about the situation and can react accordingly.

                                                            \n
                                                            kragiiAttack date faction = do\n    planets <- kragiiTargetPlanets 10 5 $ entityKey faction\n    if length planets == 0\n        then return Nothing\n        else do\n            n <- liftIO $ randomRIO (0, length planets - 1)\n            let planet = maybeGet n planets\n            let statusRec = PlanetStatus <$> fmap entityKey planet\n                                         <*> Just KragiiAttack\n                                         <*> Just Nothing\n            _ <- mapM insert statusRec\n            starSystem <- mapM (getEntity . planetStarSystemId . entityVal) planet\n            let event = join $ kragiiWormsEvent <$> planet <*> join starSystem <*> Just date\n            mapM insert event
                                                            \n

                                                            Second piece to the puzzle is status removal. In can happen manually or automatically when the prerecorded date has passed. Former method is useful for special events and latter for kind of seasonal things (good harvest for example).

                                                            \n

                                                            For example, in case of removing kragii attack status, code below serves as an example. The interesting part is deleteWhere that does actual database activity and removes all KragiiAttack statuses from given planet.

                                                            \n
                                                            removeNews event odds = MaybeT $ do\n    res <- liftIO $ roll odds\n    case res of\n        Success -> do\n            _ <- lift $ deleteWhere [ PlanetStatusPlanetId ==. kragiiWormsPlanetId event\n                                    , PlanetStatusStatus ==. KragiiAttack\n                                    ]\n            _ <- tell [ WormsRemoved ]\n            return $ Just RemoveOriginalEvent\n        Failure -> do\n            _ <- tell [ WormsStillPresent ]\n    return $ Just KeepOriginalEvent
                                                            \n

                                                            Removal of expired statuses is done based on the date, by using <=. operator to compare expiration column to given date.

                                                            \n
                                                            _ <- deleteWhere [ PlanetStatusExpiration <=. Just date]
                                                            \n

                                                            Other uses and further plans

                                                            \n

                                                            Like mentioned before, planet statuses can be used for variety of things. One such application is recording particularly good (or poor) harvest season. When such thing occurs, new planet_status record is inserted into database with expiration to set some suitable point in future. System will then automatically remove the status after that date is reached.

                                                            \n

                                                            In the meantime, every time food production is calculated, we have to check for possible statuses that might affect it and take them into account (as form of small bonus or malus).

                                                            \n

                                                            While this system is for planet statuses only, similar systems can be build for other uses (like statuses that affect a single ship or whole star system).

                                                            1. \nRulebooks tell you how to play the game.\n

                                                              2. \n

                                                            2. \nOptional books of rules add modular components to the base game. They add nuance to specific actions (for example, a book might add rules on owning and managing a castle in a fantasy world, or it might add rules on hacking in a sci fi game; these are things you can do without rules in the game, but if you want added stakes, then these books are ones you would want to obtain).\n

                                                              3. \n

                                                              4. \n

                                                              5. \n

                                                            5. \nExtra media, like novels, comics, movies, and video games, provide more information (sometimes in canon, sometimes not) about the game universe in which you are playing. Rarely do these have impact on the rules of the game, but they may provide a common language and shared experience for the players.\n

                                                              6. \n

Purchasing additional material is optional, and can either be seen as a great way to support a company providing your entertainment, or as an insidious plot by greedy corporations to rope you into a perpetual cycle of capitalism. However, RPG is a pretty healthy (and often open) system, so free and open content abounds.\n

In the menu just search for print and it will bring up the application for adding a new printer.

                                                            Two common patterns that I seem to run all the time while working on my 4x space game are functor and applicative. This episode explains them briefly.

                                                            \n

                                                            Functor

                                                            \n

                                                            Functor is a way to apply function over a structure we don’t want to alter. Type of the structure stays same, but values inside of it can change. One of the most common one is list, but there are many others.

                                                            \n

                                                            Functor type class is defined below. There’s one function fmap that takes two parameters: a function from a to b and structure f a. Result will be structure f b.

                                                            \n
                                                            class Functor f where\n    fmap :: (a -> b) -> f a -> f b
                                                            \n

                                                            This is fairly abstract, so couple example might help. First we define a little helper function that raises it’s argument to 2nd power (in the episode I talk about doubling the value, my mistake there).

                                                            \n
                                                            -- | this really raises x to 2nd power and doesn't double it\ndouble x = x * x
                                                            \n

                                                            Given a list of Int we can raise them to power of two by using fmap:

                                                            \n
                                                            > fmap double [1, 2, 3, 4, 5]\n[1, 4, 9, 16, 25]
                                                            \n

                                                            Since function being applied to structure is type of (a -> b), we can change type of the value inside of the structure. Below is example of turning list of Int to list of Text.

                                                            \n
                                                            > fmap show [1, 2, 3, 4, 5]\n["1", "2", "3", "4", "5"]
                                                            \n

                                                            This pattern isn’t limited to list and there are many others. You can even define your own ones, if you’re so inclined. The pattern stays the same. One function, fmap, that takes function of type (a -> b) and structure f a and turns it into structure of f b. Details how this is actually done depend on the specific functor.

                                                            \n

                                                            Other common functor is Maybe that is often used in cases where data might or might not be present. Maybe a has two possible values Just a indicating that value a is present and Nothing indicating that there is no value present. When fmap is used in this context, Just a will turn to Just b and Nothing will stay as Nothing.

                                                            \n
                                                            > fmap (x -> x * x) $ Just 2\nJust 4\n> fmap (x -> x * x) Nothing\nNothing
                                                            \n

                                                            Either a b is sometimes used for value that can be correct or an error. It has two value constructors Right b indicates that value is correct, Left a indicates an error case. a and b don’t have to be of same type (and usually aren’t). For example, if we have Either Text Int, then we have value where error case is Text and correct value is Int.

                                                            \n
                                                            > fmap double $ Right 5\nRight 25\n> fmap double $ Left "distance calculation failed because of flux-capacitor malfunction"\nLeft "distance calculation failed because of flux-capacitor malfunction"
                                                            \n

                                                            Functors can be placed inside of functors. The only difference is that you have to reach through multiple layers. Simplest way of doing that is to compose multiple fmap functions together like in the example below. Pay attention to in which order nested functors are defined as Maybe [Int] and [Maybe Int] are different things. Former is for case where list of Int might or might not be present. Latter is for case where there’s always list, but single element inside of the list might or might not be present.

                                                            \n
                                                            > (fmap . fmap) double (Just [1, 2, 3, 4])\nJust [1, 4, 9, 16]\n> (fmap . fmap) double Nothing :: Maybe Int\nNothing\n> (fmap . fmap) double [Just 1, Just 2, Nothing, Just 3]\n[Just 1, Just 4, Nothing, Just 9]
                                                            \n

                                                            There’s also infix operator, that does exactly same thing as fmap, called <$>. The choice which one to use is often either personal or depends on the surrounding code (because Haskell doesn’t use parenthesis in function application, so sometimes it’s easier to use fmap and sometimes <$>).

                                                            \n
                                                            > fmap show [1, 2, 3, 4, 5]\n["1", "2", "3", "4", "5"]\n\n> show <$> [1, 2, 3, 4, 5]\n["1", "2", "3", "4", "5"]
                                                            \n

                                                            There are many more functors, one place to check them is: https://hackage.haskell.org/package/base-4.12.0.0/docs/Data-Functor.html

                                                            \n

                                                            Applicative

                                                            \n

                                                            While functor works fine when function applied has only one parameter, we need applicative in cases of multiparameter functions. Calling fmap (+) [1, 2] will produce list of functions waiting for second parameter. While it would be possible to handle these cases manually, we like to abstract it to more general solution.

                                                            \n
                                                            class Functor f => Applicative f where\n    pure :: a -> f a\n    (<*>) :: f (a -> b) -> f a -> f b
                                                            \n

                                                            Applicative is similar to functor. The big difference is that function being applied is now embedded inside of same type of structure. While functor has (a -> b), applicative has f (a -> b).

                                                            \n

                                                            Below is an example of using list applicative to calculate all possible ways of summing two lists of Int.

                                                            \n
                                                            > (+) <$> [1, 2, 3] <*> [4, 5, 6]\n[5,6,7,6,7,8,7,8,9]
                                                            \n

                                                            Maybe Int works with the same pattern. First we use <$> to get started, this results Maybe containing a function that is waiting for second parameter. Then we use <*> to apply the second parameter so we get the result.

                                                            \n
                                                            > (+) <$> Just 2 <*> Just 5\nJust 7\n> (+) <$> Just 2 <*> Nothing\nNothing
                                                            \n

                                                            As long as there’s only Just a in play, result is Just, but as soon as there’s even single Nothing the end result will be nothing.

                                                            \n

                                                            If you have questions or comments, I would be delighted to hear about them. You can catch me on fediverse, where I’m Tuula@mastodon.social. Even better, you could record your own HPR episode.

                                                            There was a misunderstanding about Yannick’s show 2740 when it was discussed on the February Community News. The show was about Pop_OS!, a subject Yannick had also spoken about previously on an edition of the TuxJam podcast.

                                                            \n

                                                            The misunderstanding was that we thought this might have gone against guidelines on syndication, where in fact it did not. It was merely a case of the same subject being spoken about by the same person on two different podcasts.

                                                            Haskell is functional language where data is immutable. This means that regular for-loops don’t really exist. Looping however is very common pattern in programs in general. Here are some patterns how to do that in Haskell.

                                                            \n

                                                            Recursion

                                                            \n

                                                            Calculating Fibonacci numbers is common example (sort of like hello world in Haskell). There’s many different implementations at https://wiki.haskell.org/The_Fibonacci_sequence if you’re interested on having a look.

                                                            \n

                                                            Simple recursive definition:

                                                            \n
                                                            fibs :: Integer -> Integer\nfibs 0 = 0\nfibs 1 = 1\nfibs n = fibs (n-1) + fibs (n-2)
                                                            \n

                                                            When called with 0 result is 0. When called with 1 result is 1. For all other cases, fibs is called with values n-1 and n-1 and the results are summed together. This works fine when n is small, but calculation gets slow really quickly with bigger values.

                                                            \n

                                                            Another way is to define list of all Fibonacci numbers recursively:

                                                            \n
                                                            allFibs :: [Integer]\nallFibs = 0 : 1 : zipWith (+) allFibs (tail allFibs)
                                                            \n

                                                            Here a list is constructed. First element is 0, second element is 1 and rest of the list is obtained by summing the list with its tail (everything but the first element of the list). Definition is recursive and defines all Fibonacci numbers. However, Haskell doesn’t evaluate whole list, but only as much of it as is required.

                                                            \n

                                                            Common pattern of processing elements in a list, producing a new list:

                                                            \n
                                                            addOne :: [Integer] -> [Integer]\naddOne [] = []\naddOne (x:xs) = x + 1 : addOne xs
                                                            \n

                                                            Two cases, when called with an empty list [], result is empty list. For all other cases, list is taken apart (x:xs), x contains first element of the list and xs is rest of the list. Body of the function creates a new list where head is x + 1 and tail is addOne xs. This processes whole list of Integer by adding one to each value. It also reverses the list.

                                                            \n

                                                            Second common pattern is processing a list and reducing it to a single value:

                                                            \n
                                                            sumAll :: Integer -> [Integer] -> Integer\nsumAll n [] = n\nsumAll n (x:xs) = sumAll (n + x) xs
                                                            \n

                                                            If given list is empty (the terminal case), result is n. Second case again takes list apart (x:xs), adds x and n together and recursive call sumAll with tail of the list.

                                                            \n

                                                            This common pattern is discarding some elements of a list:

                                                            \n
                                                            evenOnly :: [Integer] -> [Integer]\nevenOnly [] = []\nevenOnly (x:xs) = \n    if even x\n        then x : evenOnly xs\n        else evenOnly xs
                                                            \n

                                                            Again, result of empty list is just empty list. In all other cases we first check if x is even. If so, new list is constructed where head is x and tail is evenOnly xs. If x isn’t even, it’s discarded and evenOnly is called recursively with tail of the list.

                                                            \n

                                                            More tools

                                                            \n

                                                            Writing recursion by hand gets tedious and sometimes confusing (if you listened to the show, you probably noticed how I got confused and had to check that evenOnly actually works as I thought it would). For that reason, there are tools that abstract these common patterns and given them names.

                                                            \n

                                                            First is map. It applies given function to each element of a list, thus producing a new list:

                                                            \n
                                                            > map (+1) [1..10]\n[2, 3, 4, 5, 6, 7, 8, 9, 10, 11]\n> map odd [1..10]\n[True, False, True, False, True, False, True, False, True, False]
                                                            \n

                                                            Second is fold. There is good article at https://wiki.haskell.org/Foldr_Foldl_Foldl%27 that talks about differences between different folds.

                                                            \n

                                                            The basic idea behind each fold is the same, they take a function and initial value and then apply them to first element of list, producing a value. This value is then applied with the function to the second element of the list and so on, until whole list has been reduced to a single value. Calculating a sum of list is so common operation that there’s specific function for that: sum.

                                                            \n
                                                            > foldr (+) 0 [1..10]\n55\n> foldl (+) 0 [1..10]\n55\n> sum [1..10]\n55
                                                            \n

                                                            scan is similar to fold, except for returning only the final value, it also returns intermediate ones. Here it’s easier to observe how scanr and scanl differ from each other:

                                                            \n
                                                            > scanr (+) 0 [1..10]\n[55,54,52,49,45,40,34,27,19,10,0]\n> scanl (+) 0 [1..10]\n[0,1,3,6,10,15,21,28,36,45,55]
                                                            \n

                                                            Last of the trifecta is filter that is used to select some of the elements in a list based on a supplied function.

                                                            \n
                                                            > filter odd [1..10]\n[1, 3, 5, 7, 9]\n> filter even [1..]\n[2, 4, 6, 8, 10, 12, 14, 16...]\n> take 5 $ filter even [1..] \n[2, 4, 6, 8, 10]
                                                            \n

                                                            Even more tools

                                                            \n

                                                            There are even more tools at our disposal. Prelude is basic library of Haskell and browsing online documentation at https://hackage.haskell.org/package/base-4.12.0.0/docs/Prelude.html might yield interesting information.

                                                            \n

                                                            For example, constructing some lists:

                                                            \n
                                                              \n
                                                            • iterate :: (a -> a) -> a -> [a] For list where function is applied repeatedly.
                                                              • \n
                                                            • repeat :: a -> [a] for a list that contains infinite amount of a.
                                                              • \n
                                                            • replicate :: Int -> a -> [a] For a list that contains finite amount of a.
                                                              • \n
                                                            • cycle :: [a] -> [a] For a infinite list that repeats same list over and over again.
                                                              • \n
                                                            \n

                                                            \n

                                                            It’s all about knowing the right tools and finding them when needed. Luckily, you don’t have to memorize big stack of notes, but can turn to https://hoogle.haskell.org/ which is Haskell API search engine. It can search based on name or type signature. I often use it to find out if somebody has already written a function that I’m thinking of writing myself.

                                                            \n

This episode is direct result of feedback that I got from previous one. If there’s Haskell topic you would love to hear more, drop me line or even better, research it by yourself and make a cool Hacker Public Radio episode.

                                                            Mount it as a usable filesystem:

                                                            Episode errata:

                                                            \n
                                                              \n

                                                            • Command substitution with $() is perfectly valid according to POSIX, and is accepted both by dash and by bash --posix. It’s not to be considered a bashism.

                                                              • \n

                                                            • I fumbled the pronunciation of the printf format string in one place and said "parenthesis" instead of "percentage sign".

                                                              • \n

                                                            • I tried to say "space" every time there’s a space, but I know I forgot it in a few places. But you probably need to look at the show notes to really make sense of the commands anyway.

                                                              • \n

                                                            You can also combine process substitution with redirection.

                                                            A coprocess in bash is a subshell to which you have access to two file descriptors: Its stdin and its stdout.

                                                            \n

                                                            The two file descriptors will be put in a bash array. To learn more about arrays, check out Dave’s series within the bash series, a whopping five-part quadrology including hpr2709, hpr2719, hpr2729, hpr2739 and hpr2756.

                                                            \n

                                                            You create a coprocess using the coproc keyword, brand spanking new since bash 4 from 2009. I am filing issues to pygments and GNU src-highlite to support it.

                                                            \n

                                                            There are two ways to call coproc. The first way is to give coproc a simple command.

                                                            \n

                                                            Example #4:

                                                            \n\n

                                                            The other way is to give coproc an explicit name and a Command Grouping.

                                                            \n

                                                            Example #5:

                                                            \n\n

                                                            Slightly less contrived example #6:

                                                            \n
                                                            $ coproc GREP (grep --line-buffered pub); printf '%s\\n' hacker public radio >&${GREP[1]}; cat <&${GREP[0]}\n[1] 25627\npublic\n^C\n$ kill %1\n[1]+  Terminated              coproc GREP ( grep --color=auto --line-buffered pub )
                                                            \n

                                                            Here grep and cat wait forever for more input, so we have to kill them to continue our lesson.

                                                            \n

                                                            But we know that GREP will only return one line, so we can just read that one line. And when we are done feeding it lines, we can close our side of its stdin, and it will notice this and exit gracefully.

                                                            \n

                                                            I’m glad I stumbled over that {YOURVARIABLE}>&- syntax for having a dereferenced variable as the left FD of a redirection. Originally I used an ugly eval.

                                                            \n

                                                            Example #7:

                                                            \n
                                                            $ coproc GREP (grep --line-buffered pub); printf '%s\\n' hacker public radio >&${GREP[1]}; head -n1 <&${GREP[0]}; exec {GREP[1]}>&-\n[1] 25706\npublic\n[1]+  Done                    coproc GREP ( grep --color=auto --line-buffered pub )
                                                            \n

                                                            There we go! Not the most brilliant example, but it shows all the relevant moving parts, and we covered a couple of caveats.

                                                            \n

                                                            Now go out and play with this and come back with an example on how this is actually useful in the real world, and submit a show!

                                                            So far we have been concentrating on separate pieces of the game. Now it’s time to put some of them together as a simulation.

                                                            \n

                                                            Overview of simulation

                                                            \n

                                                            Simulation is done in discrete steps. Each step is roughly 1 earth month (completely arbitrary decision). Shorter than that and there might not be enough happening during turns to keep things interesting. Much longer than that and player might not have enough control on how to react things.

                                                            \n

                                                            In any case, current time is stored in database in table time. There should be only one row in that table at any given time. And that row has only one value, current time. Time is stored as integer as I didn’t want to deal with problems that you get when adding fractions to a float time after time. So current time (March 2019) would be 2019.3 in game terms and stored as 20193 in database.

                                                            \n

                                                            Main processing is done in function called processTurn that is shown below. It advances time for one decimal month, removes all expired statuses as explained in episode 2768 and then loads all factions.

                                                            \n

                                                            After that, various steps of the simulation are carried out for all loaded factions. These include handling special events as explained in episode 2748 and doing observations and report writing in manner described episode 2703.

                                                            \n
                                                            processTurn :: (BaseBackend backend ~ SqlBackend,\n    BackendCompatible SqlBackend backend, PersistUniqueRead backend,\n    PersistQueryWrite backend,\n    PersistQueryRead backend, PersistStoreWrite backend, MonadIO m) =>\n    ReaderT backend m Time\nprocessTurn = do\n    newTime <- advanceTime\n    _ <- removeExpiredStatuses newTime\n    factions <- selectList [] [ Asc FactionId ]\n    _ <- mapM (handleFactionEvents newTime) factions\n    mapM_ handleFactionFood factions\n    mapM_ (handleFactionConstruction newTime) factions\n    _ <- mapM (addSpecialEvents newTime) factions\n    -- Doing observations should always be done last to ensure players have\n    -- recent reports of property they have full control, ie. planets.\n    -- Otherwise it's possible that they'll receive reports that are one\n    -- turn out of sync.\n    mapM_ (handleFactionObservations newTime) factions\n    return newTime
                                                            \n

                                                            More mapping

                                                            \n

                                                            Remember map and fmap that are used to run a function to each element in a list or general structure? mapM works in a similar way, but is used in monadic context. In processTurn function, we’re dealing with input and output and have IO monad present to allow us to do that (MonadIO m part of the type signature).

                                                            \n

                                                            If you step back a bit and squint a bit, then map :: (a -> b) -> [a] -> [b] and fmap :: (a -> b) -> f a -> f b and mapM :: Monad m => (a -> m b) -> t a -> m (t b) look pretty similar. Each take a function, structure and produce a new structure which values were created by running the given function for each element of the original structure.

                                                            \n

                                                            The difference is that map works only for lists, fmap works for functors (that were covered in episode 2778) and mapM works for structures in monadic context.

                                                            Which was a show that was recorded at Barcamp Blackpool in 2011, when a group of us got together to record a podcast, the hilarious thing was that the only place we could find to record was a stairwell which happened to be next to the toilets, definitely not family friendly but if you want a laugh have a listen.

                                                            Ken was as usual trying to recruit new hosts and interviewed me with the hope that I would become one. Well I did but it took another 5 years before I finally recorded my first show in my own right.

                                                            \n

                                                            First just to say the idea for this show comes from hpr2700 in which Ken created a script to automate the bot voice reading a list of every show that has been released on HPR, so to celebrate my 50th Show I thought I would list my shows but with me running through them and do a brief summary of the show where appropriate.

                                                            In hpr2739, Dave talked briefly about local variables. But what are they?

                                                            \n

                                                            In most modern languages, especially in compiled languages, "local" means that the value of a variable cannot be directly known, by looking up the name, outside the bounds of that function, but that’s not how it works in bash.

                                                            \n

                                                            Languages like C and Python have lexical scope. Lexical scope means local variables are local in the text. The names are local.

                                                            \n

                                                            If I’m writing code that is textually located outside the function, I cannot even describe how to access the variables within the function, because myvariable in my function is not the same variable, not the same place, as myvariable in your function.

                                                            \n

                                                            Languages like Bash and Elisp have dynamic scope. That means local variables are local in time. The names are global.

                                                            \n

                                                            What happens when you declare a variable local in bash is that the existing value of that variable is stowed away, to be brought back when your function exits.

                                                            Perl has both, and it calls them local (dynamic scope, like bash) and my (lexical scope):

                                                            You almost never want to use local in Perl, it’s mostly there for historical reasons — lexical scope is a Perl 5 feature. https://perl.plover.com/local.html covers well the remaining few and narrow exceptions where local might be useful.

                                                            \n

                                                            As dynamic scope has some valid use, it’s available in some otherwise lexically scoped languages. For example, Common LISP has the special form, and several Schemes and Racket have parameter objects:

                                                            \n\n

                                                            To dig fully into the history and flora of dynamic and lexical scope merits another episode.

                                                            Haskell is statically typed language, meaning that during compilation, programs are checked for type correctness. This means that you won’t accidentally mix for example text and numbers. Haskell does type inference. The compiler will try and figure out what kind of types would make your program to be valid in terms of types. Programmer could completely omit types, but it’s often helpful to write type signatures for at least top level definitions. These will be helpful for both the programmers and compilers.

                                                            \n

                                                            concrete types

                                                            \n

                                                            Simplest case is where types are spelled out definitely. Function add below takes two Integer parameters and produces Integer value. Note that types are written in upper case.

                                                            \n

                                                            add :: Integer -> Integer -> Integer

                                                            \n

                                                            It’s possible to not use concrete types. In following example a (note the lower case) can be anything. So function takes two values of a, a Boolea and produces a. This is useful technique for writing very general functions.

                                                            \n

                                                            choose :: a -> a -> Boolean -> a

                                                            \n

                                                            In previous example, we wouldn’t be able to do much at all with a as we don’t know its type. Sometimes we need to know a bit more about type, without specifically declaring its type. For those cases type constraints are useful.

                                                            \n

                                                            add :: (Num a) => a -> a -> a

                                                            \n

                                                            This version of add again takes two parameters, both being type a and produces value a. But (Num a) => part in the signature constraints a to be instance of Num. This type class (I’ll talk about these some other time) defines that each instance of it will have set of functions: +, -, *, negate, abs, signum and fromInteger. So now our add function can use those functions, regardless of what specific type a is.

                                                            \n

                                                            parametrized functions

                                                            \n

                                                            Types used in function signature can be parametrized. If we wanted a function that returns a first element of any list, we could have following signature: first :: [a] -> Maybe a

                                                            \n

                                                            first takes single parameter, list of a and returns Maybe a. Maybe is a type that is used to signify a value that might or might not be present and has following definition:

                                                            \n
                                                            data Maybe a =\n     Nothing\n     | Just a
                                                            \n

                                                            So our function would return Nothing when given an empty list and Just a when given a list of at least one element.

                                                            \n

                                                            using functions

                                                            \n

                                                            Function application in Haskell doesn’t require parentheses around arguments. Calling our add function is just add 1 2. If one of the values is result of another function call, we need to tell which parameters belong to which function. Using $ is one option: add 1 $ add 2 3, another option is to use parentheses: add 1 (add 2 3).

                                                            \n

                                                            When function is called with less parameters than it expect, instead of run time error you’ll going to receive a function. In following example addLots 5 will produce same value as add 1000 5:

                                                            \n
                                                            addLots = add 1000\naddLots 5
                                                            \n

                                                            Another contrived example of partial application:

                                                            \n
                                                            findPodcasts :: [Podcast] -> Text -> [Podcast]\nsearch = findPodcasts loadedPodcasts\nmyPodcasts = search "Tuula"
                                                            \n

                                                            functions as types

                                                            \n

                                                            Functions have type (that’s what the signature is for after all) and functions can be used as values. You can return function from another function or you can pass in a function as a parameter.

                                                            \n

                                                            Common example is filter, which has following signature: filter :: (a -> Bool) -> [a] -> [a]

                                                            \n

                                                            It takes two parameters, first one is function that has type a -> Bool and second one is list of a. Return value is list of a. You can produce a list of odd numbers between 1 and 10 with filter odd [1..10].

                                                            \n

                                                            anonymous functions

                                                            \n

                                                            Sometimes you need a function to pass in as a parameter, but the function is so small that you don’t want to give it a name. For those cases, anonymous function are good. If you wanted to produce a list of odd numbers that are greater that 5 in range from 1 10, you could write it as: filter (\\x -> odd x && x > 5) [1..10]. If you squint hard enough \\ looks almost like a lowercase greek letter λ.

                                                            \n

                                                            Easiest way to catch me is either email or fediverse where I’m Tuula@mastodon.social

                                                            The Blue Oak Model License 1.0.0 was just released this month. In this episode I read the license, explain where it sits in among other software licenses, and enumerate some of the problems it purports to solve.

                                                            \n

                                                            I’m no legal expert, so take all of this as sort of a rough introduction to the license.

                                                            \n

                                                            Overall, if you are looking at permissive (vs copyleft) licenses, I would strongly suggest you consider this license! It’s concise, robust, it was developed by credible people, and gives your users future-proof safety from a number of common legal traps.

                                                            \n

                                                            However: just note that it has a feature, some would say bug, that might be a big deciding factor in whether you feel comfortable with it (listen for details)

                                                            \n

                                                            Nevertheless, I believe this license, or at least its style of language, will soon become extremely common.

                                                            Not mentioned in the recording: One thing that caused me a bit of confusion at first was the term “attribution”. Kyle and the Blue Oak folks use this term mainly to talk about license terms, not authorship or credit. So for them an attribution requirement is a requirement to include the license terms with any distributed copies, not a requirement to give authorship credit to people.

                                                            \n

                                                            If you want to use this license as a starting point for your own “bespoke” license, you can! As I mention in the recording, I created my own variant of the Blue Oak license for one of my own projects. My main change was a strong requirement for downstream users to give credit to upstream contributors—not just when redistributing source code, but in all published software, books and websites created with the software!

                                                            Of course, when you make your own changes, you had better think hard about them, and if possible, get the advice of an Actual Lawyer who can discuss your particular situation.

                                                            The anti-5G campaign has been cooking for many years now, and at the epicenter of it all are two men, Lennart Hardell and Rainer Nyberg. It’s a Swedish-Finnish phenomenon that is now really making the rounds and spreading internationally, as actual commercial deployment of 5G networks draws nearer.

                                                            \n

                                                            They make it very hard to find factual information on whether millimeter-wavelength radiation actually has any different effect from the centimeter-wavelength radiation that we have been using for over two decades without any documented harmful effects, because wherever you look you just find these sites claiming that we have definitely had adverse health effects for the last two decades and the new frequency bands will definitely be far worse.

                                                            \n

                                                            When you dig deeper into the claims on these sites you find a handful of cherry-picked articles, leading back to the two men mentioned at the top, to studies with flawed methodology like self-reported surveys on mobile telephony use among cancer patients, or to the pseudoscience/media/politics/law feedback loop. And it’s all about centimeter waves, which simply have shown no conclusive sign of increasing brain cancers or any other adverse health effect related to the radiation. For every positive report made you can find one that reports brain cancer fell as we introduced mobile phones. There is a massive body of data, and if the signal were there, we would have seen it by now.

                                                            I’m no cancer researcher, but neither is Rainer Nyberg, he’s a retired professor in pedagogy. He’s a concerned citizen. https://en.wikipedia.org/wiki/Lennart_Hardell is an actual oncologist and professor who has studied carcinogens, but his research results on the wireless/cancer connection have been dismissed as "non-informative", "post hoc", "barely statistically significant" and "flawed" by his peers. There is nothing there.

I am open to the possibility that 20-50 GHz waves have different consequences from 2 GHz waves, but I’d have to hear it from a credible source.

This is still frequencies below visual light, it’s not ionizing radiation. No plausible mechanism has been suggested, and there is no clear data on any adverse effects.

The top search results go to truthaboutcancer and infowars and similar names I won’t even bother to click. I don’t want to read another article about how all cancer research after 1950 has been wrong, we should all just eat chalk to balance our acidity, and cancer is a fungus.

                                                            \n

                                                            This is rather large topic, so I split it in two episodes. Next one should follow in two weeks if everything goes as planned. First part is about modeling research, while second part concentrates on how things change over time.

                                                            \n

                                                            There’s three types of research: engineering, natural sciences and social sciences. Research costs points that are produced by various buildings.

                                                            \n

                                                            There’s three database tables, which are defined below:

                                                            Technology is enumeration of all possible technologies. Knowing these enable player to build specific buildings and space ships, enact various laws and so on. In the end this will be (hopefully) large list of technologies.

                                                            \n

                                                            All research belong to one of the top categories that are shown below:

                                                            \n

                                                            ResearchCategory is more fine grained division of research. Each of the categories is further divided into sub-categories. Only EngineeringSubField is shown below, but other two are similarly divided.

                                                            \n

                                                            ResearchScore is measure of how big some research is. It has type parameter a that is used to further quantify what kind of ResearchScore we’re talking about.

                                                            \n
                                                            newtype ResearchScore a = ResearchScore { unResearchScore :: Int }\n    deriving (Show, Read, Eq, Ord, Num)
                                                            \n

                                                            TotalResearchScore is record of three different types of researches. I’m not sure if I should keep it as a record of three fields or if I should change it so that only one of those values can be present at any given time.

                                                            \n
                                                            data TotalResearchScore a = TotalResearchScore\n    { totalResearchScoreEngineering :: ResearchScore EngineeringCost\n    , totalResearchScoreNatural :: ResearchScore NaturalScienceCost\n    , totalResearchScoreSocial :: ResearchScore SocialScienceCost\n    }\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Following singleton values are used with ResearchScore and TotalResearchScore to quantify what kind of value we’re talking about.

                                                            \n
                                                            data EngineeringCost = EngineeringCost\n    deriving (Show, Read, Eq)\n\ndata NaturalScienceCost = NaturalScienceCost\n    deriving (Show, Read, Eq)\n\ndata SocialScienceCost = SocialScienceCost\n    deriving (Show, Read, Eq)\n\ndata ResearchCost = ResearchCost\n    deriving (Show, Read, Eq)\n\ndata ResearchProduction = ResearchProduction\n    deriving (Show, Read, Eq)\n\ndata ResearchLeft = ResearchLeft\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Finally there’s Research, which is a record that uses many of the types introduced earlier. It describes what Technology is unlocked upon completion, what’s the cost is and if there are any technologies that have to have been researched before this research can start. The tier of research isn’t currently used for anything, but I have vague plans what to do about it in the future.

                                                            \n
                                                            data Research = Research\n    { researchName :: Text\n    , researchType :: Technology\n    , researchCategory :: ResearchCategory\n    , researchAntecedents :: [Technology]\n    , researchCost :: TotalResearchScore ResearchCost\n    , researchTier :: ResearchTier\n    }\n    deriving (Show, Read, Eq)

                                                            \n

                                                            Putting all this together, we can define a list of Research. Since finding an entry from this list based on research type of it is such a common operation, we also define another data structure for this specific purpose. Map in other programming languages is often known as dictionary, associative array or hash map. It stores key-value - pairs. In our case Technology is used as key and Research as value. We define it based on the list previously defined:

                                                            \n
                                                            techMap :: Map.Map Technology Research\ntechMap = Map.fromList $ (\\x -> (researchType x, x)) <$> unTechTree techTree

                                                            Knightwise, in HPR 2798, made the argument that podcasts are better if they are done by \"pirates\", i.e. not by corporations, but by individuals with something to say. While I see some merit in this view, I think the more significant feature of podcasts is that it gets us away from \"broadcasting\" (shows aimed at the lowest common denominator) and towards \"narrowcasting\", an environment where small niche interests can find an audience and thrive since podcasting does not require a lot of resources. But I do appreciate the chance to hear some radio programs that I would not otherwise be able to listen to when they are offered as podcasts.

                                                            \n

                                                            This is the second of a pair of episodes looking at redirection in Awk scripts.

                                                            In this episode I will spend some time looking at the getline command used for explicit input (as opposed to the usual implicit sort), often with redirection. The getline command is a complex subject which I will cover only relatively briefly. You are directed to the getline section of the GNU Awk User’s Guide for the full details.

                                                            Last time we looked how to model technology and research. This time we’ll do some actual research. I’m skipping over some of the details as the episode is long enough as it is. Hopefully it’s still possible to follow with the show notes.

                                                            \n

                                                            Main concepts that I’m mentioning: Technology allows usage of specific buildings, ship components and such. Research unlock technologies and may have antecedents that has to be completed before the research can be started. Research cost is measure of how expensive a research is in terms of research points, which are produced by different buildings.

                                                            \n

                                                            Earlier I modeled tech tree as Map that had Technology as keys and Research as values. I realized that this is suboptimal and will replace it at some point in the future.

                                                            \n

                                                            \n

                                                            There’s three resources that client can connect to. First one is for retrieving list of available research, second one for manipulating current research and last one for retrieving info on how much research points is being produced.

                                                            \n

                                                            Simulation

                                                            \n

                                                            Simulation of research is done by handleFactionResearch, which does simulation for one faction for a given date. After calculating current research point production and retrieving list of current research, function calculates progress of current researches. Unfinished ones are written back to database, while completed are moved into completed_research table. Final step is updating what research will be available in the next turn.

                                                            \n
                                                            handleFactionResearch date faction = do\n    production <- totalProduction $ entityKey faction\n    current <- selectList [ CurrentResearchFactionId ==. entityKey faction ] []\n    let updated = updateProgress production <$> current\n    _ <- updateUnfinished updated\n    _ <- handleCompleted date updated $ entityKey faction\n    _ <- updateAvailableResearch $ entityKey faction\n    return ()
                                                            \n

                                                            Research point production

                                                            \n

                                                            Research points are produced by buildings. So first step is to load all planets owned by the faction and buildings on those planets. Applying researchOutput function to each building yields a list of TotalResearchScore, which is then summed up by mconcat. We can use mconcat as TotalResearchScore is a monoid (I talked about these couple episodes ago).

                                                            \n
                                                            totalProduction fId = do\n    pnbs <- factionBuildings fId\n    let buildings = join $ fmap snd pnbs\n    return $ mconcat $ researchOutput . entityVal <$> buildings
                                                            \n

                                                            researchOutput function below uses pattern matching. Instead of writing one function definition and case expression inside of it, we’re writing multiple definitions. Each of them matches building of different type. First example is definition that is used for ResearchComplex, while second one is for ParticleAccelerator. Final case uses underscore to match anything and indicate that we’re not even interested on the particular value being matched. mempty is again from our monoid definition. It is empty or unit value of monoid, which in case of TotalResearchScore is zero points in all research categories.

                                                            \n
                                                            researchOutput Building { buildingType = ResearchComplex } =\n    TotalResearchScore\n    { totalResearchScoreEngineering = ResearchScore 10\n    , totalResearchScoreNatural = ResearchScore 10\n    , totalResearchScoreSocial = ResearchScore 10\n    }\n\nresearchOutput Building { buildingType = ParticleAccelerator } =\n    TotalResearchScore\n    { totalResearchScoreEngineering = ResearchScore 15\n    , totalResearchScoreNatural = ResearchScore 15\n    , totalResearchScoreSocial = ResearchScore 0\n    }\n\nresearchOutput _ = mempty
                                                            \n

                                                            Updating progress

                                                            \n

                                                            Moving research forward is more complex looking function. There’s bunch of filtering and case expressions going on, but the idea is hopefully clear after a bit of explanation.

                                                            \n

                                                            updateProgress takes two parameters, total production of research points and current research that is being modified. This assumes that there are only one of each categories of research going on at any given time. If there were more, we would have to divide research points between them by some logic. Function calculates effect of research points on current research and produces a new current research that is the end result.

                                                            \n

                                                            Perhaps the most interesting part is use of lenses. For example, line entityValL . currentResearchProgressL +~ engResearch $ curr means that curr (which is Entity CurrentResearch) is used as starting point. First we reach to data part of Entity and then we focus on currentResearchProgress and add engResearch to it. This results a completely new Entity CurrentResearch being constructed, which is otherwise identical with the original, but the currentResearchProgress has been modified. Without lenses we would have to do this destructuring and restructuring manually.

                                                            \n
                                                            updateProgress :: TotalResearchScore ResearchProduction -> Entity CurrentResearch -> Entity CurrentResearch\nupdateProgress prod curr =\n    case researchCategory <$> research of\n        Just (Engineering _) ->\n            entityValL . currentResearchProgressL +~ engResearch $ curr\n\n        Just (NaturalScience _) ->\n            entityValL . currentResearchProgressL +~ natResearch $ curr\n\n        Just (SocialScience _) ->\n            entityValL . currentResearchProgressL +~ socResearch $ curr\n\n        Nothing ->\n            curr\n    where\n        research = Map.lookup (currentResearchType . entityVal $ curr) techMap\n        engResearch = unResearchScore $ totalResearchScoreEngineering prod\n        natResearch = unResearchScore $ totalResearchScoreNatural prod\n        socResearch = unResearchScore $ totalResearchScoreSocial prod
                                                            \n

                                                            Writing unfinished research back to database is short function. First we find ones that hasn’t been finished by filtering with (not . researchReady . entityVal) and then we apply replace to write them back one by one.

                                                            \n
                                                            updateUnfinished updated = do\n    let unfinished = filter (not . researchReady . entityVal) updated\n    mapM (\\x -> replace (entityKey x) (entityVal x)) unfinished
                                                            \n

                                                            Handling finished research starts by finding out which ones were actually completed by filtering with (researchReady . entityVal) and their research type with currentResearchType . entityVal. Rest of the function is all about database actions: creating entries into completed_research and adding news entries for each completed research, then removing entries from current_research and available_research.

                                                            \n
                                                            handleCompleted date updated fId = do\n    let finished = filter (researchReady . entityVal) updated\n    let finishedTech = currentResearchType . entityVal <$> finished\n    insertMany_ $ currentToCompleted date . entityVal <$> finished\n    insertMany_ $ researchCompleted date fId . (currentResearchType . entityVal) <$> finished\n    deleteWhere [ CurrentResearchId <-. fmap entityKey finished ]\n    deleteWhere [ AvailableResearchType <-. finishedTech\n                , AvailableResearchFactionId ==. fId ]
                                                            \n

                                                            Available research

                                                            \n

                                                            Figuring out what researches will be available for the next turn takes several steps. I won’t be covering random numbers in detail, they’re interesting enough for an episode on their own. It’s enough to know that g <- liftIO getStdGen gets us a new random number generator that is seeded by current time.

                                                            \n

                                                            updateAvailableResearch starts by loading available research and current research for the faction and initializing a new random number generator. g can be used multiple times, but it’ll always return same sequence of numbers. Here it doesn’t matter, but in some cases it might. getR is helper function I wrote that uses random number generator to pick n entries from a given list. n in our case is hard coded to 3, but later on I’ll add possibility for player to research technologies that raise this limit. newAvailableResearch (we’ll look into its implementation closer just in a bit) produces a list of available research for specific research category. These lists are combined with <> operator and written into database with rewriteAvailableResearch.

                                                            \n
                                                            updateAvailableResearch fId = do\n    available <- selectList [ AvailableResearchFactionId ==. fId ] []\n    completed <- selectList [ CompletedResearchFactionId ==. fId ] []\n    g <- liftIO getStdGen\n    let maxAvailable = ResearchLimit 3\n    -- reusing same g should not have adverse effect here\n    let engCand = getR g (unResearchLimit maxAvailable) $ newAvailableResearch isEngineering maxAvailable available completed\n    let natCand = getR g (unResearchLimit maxAvailable) $ newAvailableResearch isNaturalScience maxAvailable available completed\n    let socCand = getR g (unResearchLimit maxAvailable) $ newAvailableResearch isSocialScience maxAvailable available completed\n    rewriteAvailableResearch fId $ engCand <> natCand <> socCand
                                                            \n

                                                            newAvailableResearch is in charge of figuring out what, if any, new research should be available in the next turn. In case where amount of currently available research is same or greater than research limit, empty list is returned, otherwise function calculates candidates and returns them. Logic for that is following:

                                                            \n

                                                            • candidates are research of specific category of those that has been unlock and unresearched
                                                              • \n
                                                            • unlocked and unresearched are unlocked ones that are in list of known technology
                                                              • \n
                                                            • unlocked research are ones with antecedents available in tech tree
                                                              • \n
                                                            • known technology are ones in list of completed research
                                                              • \n
                                                            \n

                                                            and complete definition of the function is shown below:

                                                            \n
                                                            newAvailableResearch selector limit available completed =\n    if ResearchLimit (length specificCategory) >= limit\n        then []\n        else candidates\n    where\n        specificCategory = filter (availableResearchFilter selector) available\n        candidates = filter (selector . researchCategory) unlockedAndUnresearched\n        unlockedAndUnresearched = filter (\\x -> researchType x `notElem` knownTech) unlockedResearch\n        unlockedResearch = filter (antecedentsAvailable knownTech) $ unTechTree techTree\n        knownTech = completedResearchType . entityVal <$> completed\n\n\navailableResearchFilter f x =\n    maybe False (f . researchCategory) res\n    where\n        res = Map.lookup (availableResearchType $ entityVal x) techMap
                                                            \n

                                                            Final step of the simulation of research is to update database with new available research. mkUniq is helper function that removes duplicate elements from a list. It’s used in rewriteAvailableResearch function to make a list that contains all unique top research categories (engineering, natural sciences and social sciences). If the resulting list isn’t empty, we’ll use it to remove all available research for those top categories and insert new available research.

                                                            \n
                                                            rewriteAvailableResearch fId res = do\n    let cats = mkUniq $ fmap (topCategory . researchCategory) res\n    unless (null cats) $ do\n        deleteWhere [ AvailableResearchFactionId ==. fId\n                    , AvailableResearchCategory <-. cats ]\n        insertMany_ $ researchToAvailable fId <$> res
                                                            \n

                                                            Now everything is ready for next round of simulation.

                                                            Hi All,

                                                            \n

                                                            Under safe harbor provisions, we as volunteers are usually insulated from any copyright issues that may arise in the shows. \"We do not vet, edit, moderate or in any way censor any of the shows on the network, we trust you to do that.\"

                                                            \n

                                                            This we got by accident because \"This is a long standing tradition arising from the fact that HPR is a community of peers who believe that any host has as much right to submit shows as any other.\"

                                                            \n

                                                            In the show notes associated with hpr2829 on 2019-06-06, the host included the following text \"For all included materials: If anyone feels they have right to any material in this show please let me know and I will comply.\"

                                                            \n

                                                            This violates the HPR upload policy.

                                                            \n

                                                            \"Never include content, for example music, in your show that you do not have permission to redistribute.

                                                            \n

                                                            As it was clear that they were not in compliance, I contacted the host. The host has been very helpful and has already removed some of the content but commented \"There are still 2 audio clips included. I claim I can use them on the basis off fair use principles.\"

                                                            \n

                                                            While the host may be correct, if they are not, then it is me and not the host that will be held responsible for posting it. I do not want that responsibility.

                                                            \n

                                                            Under the current HPR rules I am allowed to reject this submission.

                                                            \n

                                                            Before I do, I would appreciate as much feedback as possible on this topic so that we can gauge the opinions of the HPR Community as a whole.

                                                            \n

                                                            When it comes to monitoring your network, and the machines on it, you have a lot of options. But, let’s face it : none of those are easy to implement, and configuring a monitoring tool, whether it’s an open-source or a proprietary one, is often complex and time consuming.

                                                            \n

What is NEMS, how can it help us, and what infrastructure does it require? Those are a few of the questions I asked Robbie Ferguson, the maintainer of NEMS, who joined me on Easter week-end for a little chat.

Although, if she was to do that, it would probably turn out to be great pictures. No, Wendy is a professional photographer, and to run her business, she uses free and opensource software.

                                                            I got really good comment on episode 2778 - Functor and applicative in Haskell from Beeza that I’m including below:

                                                            \n

                                                            I’ve been writing software for over 30 years but I find the syntax of Haskell anything but intuitive - in fact less so than any other programming language I have looked at. Thanks to your excellent show notes I can make sense of it but I have to say I would not like to have to develop a project using this language.

                                                            \n

                                                            Obviously I am missing the point as nobody would design a language with the intention of its being difficult to use. Perhaps you could produce another episode addressing the question “Why Haskell?”

                                                            Hello HPR land, this is Tony Hughes again coming to you from Blackpool in the UK.

                                                            \n

                                                            During my last episode, which was my 50th for HPR, I realized that my ‘Bag’ has changed considerably since recording my episode hpr2065 about it back in July 2016. So this is an update on what I currently carry in my ‘Geek’ Bag when out and about.

                                                            \n

                                                            I have several laptops which are used for different things at different times so may or may not be in the bag/bags depending on what I am doing. This is the list:

                                                            \n
                                                              \n

                                                            • Dells E6220 x 2, E7250, E7440 and E6540
                                                              • \n
                                                            \n

                                                            Recently I have moved more to Dell laptops and the Dell E7440 is a great compromise of portability and usability with its 14" 1080p screen, but if I want light and long battery life the Toshiba z30 is a fantastic little PC with all day battery life and a great 13.3" screen.

                                                            \n

                                                            But all the others have their place in the bag, for demonstrating Linux Distros at events or at my LUG.

                                                            \n

                                                            So the next thing that makes it into the bag is my ZoomH2 recorder that goes with me for recording interviews at events I attend, with the intention of producing HPR shows.

                                                            \n

                                                            I also have some tools, the first is a little set of a screwdriver and small driver bits made by Draper this is handy for laptop tear downs as it has all the necessary bit heads needed to work on electronics. I also carry a small set of pliers and a wire cutter in the bag.

                                                            \n

                                                            I also carry a 10000mA battery pack for charging my mobile phone if needed while out and about. In conjunction with this a I carry several micro USB charging cables and a USB C cable for the increasing number of USB C devices around these days.

                                                            \n

                                                            In the bag are also a couple of 128Gb SSD’s as spares for quick swap outs, if I don’t want to wipe a drive but wish to test a new OS, or for those times the only solution to helping someone rescue an older laptop is to stick an SSD into it.

                                                            I generally carry my 1Tb portable USB3 HDD around with me as I store a large number of current Linux ISO files for burning to a flash drive to create boot discs. With that it goes without saying that I have a few spare flash drives in the bag for just this use. I also usually carry a few SD cards for creating Raspberry Pi images if needed.

                                                            \n

                                                            Other items include a USB WiFi card as a backup if I have a WiFi malfunction, or I’m working on a machine without its own WiFi card.

                                                            Well that’s about it for what I’m currently carrying in my bag, but before I go a bit of sad news. Many of you have heard me talk of my latest bargains from the Computer Auction I have frequented since 2006. Well sadly NO MORE, Northern Realisations after 20 years of trading have closed their doors for the last time, so I need to find another source of cheap PC equipment. As they say: All good things come to an end.

                                                            In this episode I talk about my new 1969 Sony TC-222-A portable reel-to-reel tape recorder. I found it about 3 weeks ago at Hand-Up Thrift store in Lafayette Louisiana for $5. It was in partially working condition, without a power cord, and in need of some work. I cleaned the contact points, overhauled the fast-forward idler wheel, lubricated both of the tape shafts, replaced the belts, hacked an old electric razor cord to work as a power cord, and tightened up the record linkage. One thing I still can't get working is recording using the microphone.

                                                            \n\n

                                                            I spend about half of this episode talking about trying to make a super-long recording fit on a 5-inch reel and playing at 4.8 cm/second. I use Kimiko Ishizaka's wonderful Open Goldberg Variations and Open Well-Tempered Clavier as the music. To do this, I speeded up all of the tracks to play at 4x speed, for which I use the following script to loop through all mp3s in the current directory and subject them to the appropriate sox command:

                                                            \n\n
                                                            \n#!/bin/bash\n\nfor i in *.mp3; do\n# speed em up 4x\n  infile=$(basename $i)\n  stem=$(basename \"$i\" .mp3)\n  outfile=\"$stem\"_4x.mp3\n  sox $infile $outfile speed 4.0\n  sleep .1\ndone\n
                                                            \n\n

                                                            It worked! Well. The script and sox command worked. Recording the 4x-speed audio at 19 cm/second and then playing back at 4.8 cm/second also mostly worked, I just had a very poor-quality tape so it sounded pretty bad. The speed was just about right, though. In fact when I compared pitch against my piano, it was EXACTLY right. I may try again with a better tape. (BTW I said my tape was \"old new stock,\" but obviously I meant \"new old stock.\")

                                                            The page at https://www.hackerpublicradio.org/advanced_rss_settings.php describes a series of features that allow the specification of a tailored RSS feed.

                                                            \n

                                                            One of the features is 'gomax=1' which includes shows in the queue scheduled for the future. For example, the following URL requests 30 OGG format shows including those scheduled for the future:

                                                            \n

                                                            \n

                                                            However, there is a problem with this, caused by the way we direct downloads to archive.org. We usually upload the next week’s shows to archive.org, but not all future shows as they arrive. This means that the links to some future shows returned by the feed point to currently non-existent episodes.

                                                            \n

                                                            This has been the case ever since we moved to using archive.org in this way, in late 2017. We have not received any comments or complaints about it in that time, so the question is:

                                                            \n

                                                            Does anyone use 'gomax=1'?

                                                            There’s lots of random and similar sounding words in this episode. I hope you can still follow what I’m trying to explain, but I’m aware that it might be hard.

                                                            \n

                                                            Haskell functions are pure, meaning that they will always produce same values for same set of arguments. This might sound hard when you want to generate random numbers, but it turns out that the solution isn’t too tricky.

                                                            \n

                                                            First part to the puzzle is type class RandomGen:

                                                            \n
                                                            class RandomGen g where\n    next :: g -> (Int, g)\n    genRange :: g -> (Int, Int)\n    split :: g -> (g, g)
                                                            \n

                                                            next produces tuple, where first element is random Int and second element is new random generator. genRange returns tuple defining minimum and maximum values this generator will return. split produces tuple with two new random generators.

                                                            \n

                                                            Using RandomGen to produce random values of specific type or for specific range requires a bit of arithmetic. It’s easier to use Random that defines functions for that specific task:

                                                            \n
                                                            class Random a where\n    randomR :: RandomGen g => (a, a) -> g -> (a, g)\n    random :: RandomGen g => g -> (a, g)\n    randomRs :: RandomGen g => (a, a) -> g -> [a]\n    randoms :: RandomGen g => g -> [a]\n    randomRIO :: (a, a) -> IO a\n    randomIO :: IO a
                                                            \n
                                                              \n
                                                            • randomR, when given range and random generator, produces tuple with random number and new generator
                                                              • \n

                                                            In short, RandomGen is source of randomness and Random is datatype specific way of generating random values using random generator RandomGen.

                                                            Final part of the puzzle is where to get RandomGen? One could initialize one manually, but then it wouldn’t be random. However, there’s function getStdGen that will seed RandomGen using OS default random number generator, current time or some other method. Since it has signature of getStdGen :: IO StdGen, one can only call it in IO monad.

                                                            \n

                                                            Functions that operate with IO can only be called from other IO functions. They can call pure functions, but pure functions can’t call them. So there’s two options: have the code that needs random numbers in effectful function or get RandomGen in effectful function and pass it to pure function.

                                                            \n

                                                            Example

                                                            \n
                                                            import System.Random\nimport Data.List\n\n-- | get n unique entries from given list in random order\n-- | if n > length of list, all items of the list will be returned\ngetR :: RandomGen g => g -> Int -> [a] -> [a]\ngetR g n xs =\n    fmap (xs !!) ids\n    where\n        ids = take (min n $ length xs) $ nub $ randomRs (0, length xs - 1) g\n\n-- | Returns 4 unique numbers between 1 and 10 (inclusive)\ntest :: IO [Int]\ntest = do\n    g <- getStdGen\n    return $ getR g 4 [1..10]
                                                            \n

                                                            In closing

                                                            \n

                                                            Pseudo randomness doesn’t require IO, only seeding the generator does. Simple computation that don’t require many calls to random are easy enough. If you need lots of random values, MonadRandom is better suited. It takes care of carrying implicit RandomGen along while your computation progresses.

                                                            We are using this as an opportunity to have a round-table discussion about the series, about Awk, and where we recommend the listeners should go from here. Including this one we have produced 16 episodes covering the features most likely to be used in pipelines on the command line or in simple shell and awk scripts.

No very good text processing features built-in, so Gnu Awk (and sed) was a great way to handle the data we were using to generate accounts for new students each year. Could easily spot bad records, do some data validation (for example impossible dates of birth).

                                                            Major parts

                                                            \n

                                                            Two major parts about vehicle designer are components and chassis.

                                                            \n

                                                            Components are modular pieces of vehicle that are assembled on chassis. They can, among other things, be things lie star sails, astrolabe navigators or long range sensor. Each component is defined by two values ComponentId and ComponentLevel. If you know these two values, you’ll be able to find out details of the component. ComponentId tells what component it is and ComponentLevel the general knowledge of it. When component is first discovered as a result of research, it’s just a prototype and as a such doesn’t function particularly well. Further research refines it and factories are able to produce higher quality components.

                                                            \n

                                                            Full definition of component is show below:

                                                            \n
                                                            data Component = Component\n    { componentId :: ComponentId\n    , componentLevel :: ComponentLevel\n    , componentName :: ComponentName\n    , componentDescription :: ComponentDescription\n    , componentWeight :: Weight\n    , componentSlot :: ComponentSlot\n    , componentType :: [ ComponentPower ]\n    , componentCost :: RawResources ResourceCost\n    , componentChassisType :: ChassisType\n    }\n    deriving (Show, Read, Eq, Ord)
                                                            \n

                                                            Two particularly interesting fields are componentSlot and componentType. componentSlot has type of ComponentSlot and defines what kind of slot the component occupies in chassis. As there are limited amount of slots in each chassis, designer needs to make compromises on what components to install. componentType has type of ComponentPower, which defines what component does in general. It could be sensor or provide supplies for the vehicle for example.

                                                            \n

                                                            Technology requirements are defined by function: componentRequirements :: ComponentId -> Maybe Technology. It defines which technology unlock a given component. Part of the definition is show below. Each and every ComponentId has to be handled.

                                                            \n
                                                            componentRequirements ShipLongRangeSensors = Just HighSensitivitySensors\ncomponentRequirements ShipBridge = Nothing\ncomponentRequirements VehicleWheeledMotiveSystem = Nothing\ncomponentRequirements VehicleHoverMotiveSystem = Just HoverCrafts\n...
                                                            \n

                                                            Second major part of the designer are chassis. They’re stored in database, as I wanted a bit more flexible system than hardcoding as I did with components. Following piece of configuration is used to define database table and generated data for Haskell code. Most of the fields are probably easy enough to guess. type with type of ChassisType defines if this particular chassis is for example a land vehicle or a space ship. Various slot fields on other hand define amount of particular slots that the chassis offers.

                                                            \n
                                                            Chassis json\n    name ChassisName\n    tonnage Weight\n    type ChassisType\n    technology Technology Maybe\n    armourSlots SlotAmount\n    innerSlots SlotAmount\n    outerSlots SlotAmount\n    sensorSlots SlotAmount\n    weaponSlots SlotAmount\n    engineSlots SlotAmount\n    motiveSlots SlotAmount\n    sailSlots SlotAmount\n    deriving Show Read Eq
                                                            \n

                                                            Not all chassis are equal and some (probably pretty much every one of them) have some sort of requirements that has to be fulfilled when designing a vehicle. For example, space ships require a bridge for captain and star sails. Bawley, smallest of the working ships has room for two star sails, but requires only one of them to be installed in order to be a valid design. Flyboat on the other hand is smaller ship built for speed and always requires two set of sails.

                                                            \n

                                                            This data is stored in required_component table and represented as RequiredComponent data. Both are generated from the definition show below:

                                                            \n

                                                            With all that data, we can now design a vehicle. Process is roughly the following:

                                                              • \n
                                                            • remember to check that maximum tonnage isn’t exceeded and that there’s enough slots and requirements are met
                                                              • \n
                                                            • fill in name
                                                              • \n

                                                            \n

                                                            Completed design is saved in two different tables. First one design holds info like name of the design, faction that design belongs to and used chassis. planned_component holds info about which components are planned to be installed and in what quantity.

We look at how quantum computing will affect encryption going forward, and show that we are already working on quantum-resistant encryption.

                                                            Before the days of the PC, application architectures were often very simple - being little more than the executable itself and any input files. The constraints of the early PC’s very limited resources required new architectures to make the most of those resources.

                                                            \n

                                                            We now have a situation where most applications either install, or require the presence of, multiple runtime dependencies. Each dependency has an interface which allows communication between itself and the application, but every interface presents an attack surface with the potential to be exploited by a malicious 3rd party.

                                                            \n

                                                            Modern computers do not have those same resource constraints yet we are still developing applications using the principles that applied 3 decades ago.

                                                            Re-usable functionality can be internalised through static linking at compile-time or by code inclusion (along the lines of a .h file in C/C++)

                                                            Podcast episode is about two things, serializing custom data with Persistent and IsString typeclass.

                                                            \n

                                                            I’m using Persistent in conjunction with Yesod (web framework). Process in short is that data is defined in /config/models file that is used in compile time to generate data type definitions for Haskell. Same information is used to create schema for the database when Yesod application starts. It can even do simple migrations if schema changes, but I wouldn’t recommend using that in production.

                                                            \n

                                                            Persistent maps information between database and program written in Haskell. There’s pre-existing mappings for things like text and various kinds of numbers. In case one wants to use custom data type, compiler can automatically generate needed mapping. This automatic generation works well with enumerations and very complex data.

                                                            \n

                                                            For example, following piece defines enumeration BuildingType that is mapped in varchar field in database. Enumeration is thus stored as text.

                                                            \n
                                                            data BuildingType = SensorStation\n    | ResearchComplex\n    | Farm\n    | ParticleAccelerator\n    | NeutronDetector\n    | BlackMatterScanner\n    | GravityWaveSensor\n    deriving (Show, Read, Eq)\n\nderivePersistField "BuildingType"
                                                            \n

                                                            For newtypes, automatic deriving works too, but generates (in my opinion) extra information that isn’t needed. This extra information causes data saved as text. For those cases, manual mapping can be used.

                                                            \n

                                                            Our example is for StarDate, which is just glorified Int. I’m using newtype to make StarDate distinct from any other Int, even when it behaves just like Int.

                                                            newtype StarDate = StarDate { unStarDate :: Int }\n    deriving (Show, Read, Eq, Num, Ord)\n\ninstance PersistField StarDate where\n    toPersistValue (StarDate n) =\n        PersistInt64 $ fromIntegral n\n\n    fromPersistValue (PersistInt64 n) =\n        Right $ StarDate $ fromIntegral n\n\n    fromPersistValue _ =\n        Left "Failed to deserialize"\n\n\ninstance PersistFieldSql StarDate where\n    sqlType _ = SqlInt64
                                                            \n

                                                            One more trick, that doesn’t directly relate to Persistent is IsString type class. Instead of having to specify all the time what type text literal is, one can let compiler to deduce it from usage.

                                                            \n

                                                            For example, if I had a newtype like:

                                                            \n
                                                            newtype PlanetName = PlanetName { unPlanetName :: Text }
                                                            \n

                                                            I can turn on OverloadedStrings pragma and create IsString instance:

                                                            \n
                                                            instance IsString PlanetName where\n    fromString = PlanetName . fromString
                                                            \n

                                                            Now I can write: placeName = "Earth" instead of placeName = PlanetName "Earth" and compiler can deduce correct type based on how the placeName is used.

                                                            \n

It is not enough to simply say that “A study shows…” without also looking at what kind of study it is how powerful the results are. We look at the different kinds of studies and rank them from top to bottom.

                                                            Unfortunately, on Friday July 12th the archive.org copy of the show hpr2855 :: HPR NYE Show 2018-2019 part 6 was found to have been truncated and to consist only of the introduction and final part; no actual content.

                                                            The problem was detected during the morning of Friday and was rectified during the afternoon (UK time). The RSS feeds were adjusted to ensure the show was re-downloaded and all podcatchers should have received the correct version the next time they checked the feed.

                                                            I found a pretty cool little handheld cassette recorder at Salvation Army Thrift Store for 99 cents yesterday. It was non-functioning. I was able to get it working again by 1. cleaning corrosion from battery compartment; 2. replacing the nasty gooey belt; 3. repairing the battery compartment, which had a broken-off spring for one of the battery's negative connections. The most interesting feature of the device is that it has a variable-speed knob for playback at higher speed. I demonstrate this in the podcast.

                                                            1. Mince half the shallot (or all of it, I'm not the boss of you). Trim and shred the zucchini. Prepare a mixing bowl lined with a paper towel.
                                                              2. \n
                                                            2. Preheat oven to 500 F
                                                              3. \n
                                                            3. Drizzle some oil into a large oven-proof pan (if you've got one) and cook the sausage, with half the Italian seasoning, over medium heat, breaking it into bite-sized pieces as you cook it. Transfer to the mixing bowl for later.
                                                              4. \n
                                                            4. Add another drizzle of olive oil, and shred the zucchini into the pan. Add shallot, and cook until the zucchini shrinks to ⅔ of its size (about 5 minutes). Transfer to the mixing bowl with the sausage.
                                                              5. \n
                                                            5. Wipe out the pan with a paper towel. Melt 1 tbsp of butter over medium heat, and add orzo, stirring pretty frequently for 2-3 minutes.
                                                              6. \n
                                                            6. Stir in the rest of the Italian seasoning, along with the water, tomatoes, and stock concentrate. Bring to a boil and stir until orzo is done - around 12 - 14 minutes.
                                                              7. \n
                                                            7. Drain excess liquid from the zucchini and sausage.
                                                              8. \n
                                                            8. Mix sausage & zucchini into orzo mixture, with 1 tbsp of butter. Season with salt & pepper, if you want.
                                                              9. \n
                                                            9. If you don't have an oven-proof pan, you're going to want to transfer everything over to a large baking dish of some kind. 13x9" works for me.
                                                              10. \n
                                                            10. Cover the mixture in mozzarella cheese and panko breadcrumbs - in that order!
                                                              11. \n
                                                            11. Place dish in the oven for 2-3 minutes, until the breadcrumbs are toasted.
                                                              12. \n

                                                            \n

                                                            I use pdmenu a lot to help me do work on my main desktop PC. I did an HPR show on pdmenu on 13 December 2017 and the author Joey Hess responded in show 2459.

                                                            \n

                                                            In the intervening time I have also integrated Zenity into my menus. This is a GUI tool which generates a number of different pop-up windows known as dialogs, which can display information, or into which information can be typed. The capabilities provided by pdmenu are a little too basic to enable me to do what I need to do.

                                                            \n

                                                            I thought it might be of interest to show some examples of how I use this tool with pdmenu.

                                                            Background

                                                            \n

                                                            Type classes are Haskell’s way of doing ad hoc polymorphics or overloading. They are used to defined set of functions that can operate more than one specific type of data.

                                                            \n

                                                            Equality

                                                            \n

                                                            In Haskell there’s no default equality, it has to be defined.

                                                            \n

                                                            There’s two parts to the puzzle. First is type class Eq that comes with the standard library and defines function signatures for equality and non-equality comparisons. There’s type parameter a in the definition, which is filled by user when they define instance of Eq for their data. In that instance definition, a is filled with concrete type.

                                                            \n
                                                            class  Eq a where\n  (==) :: a -> a -> Bool\n  (/=) :: a -> a -> Bool\n\n  x /= y = not (x == y)
                                                            \n

                                                            Definition above can be read as “class Eq a that has two functions with following signatures and implementations”. In other words, given two a, this function determines are they equal or not (thus Bool as return type). /= is defined in terms of ==, so it’s enough to define one and you get other one for free. But you can still define both if you’re so included (maybe some optimization case).

                                                            \n

                                                            If we define our own Size type, like below, we can compare sizes:

                                                            \n
                                                            data Size = Small | Medium | Large\n    deriving (Show, Read)\n\ninstance Eq Size where\n    Small == Small = True\n    Medium == Medium = True\n    Large == Large = True\n    _ == _ = False
                                                            \n

                                                            And here’s couple example comparisons.

                                                            \n
                                                            > Small == Small\nTrue\n> Large /= Large\nFalse
                                                            \n

                                                            Writing these by hand is both tedious and error prone, so we usually use automatic derivation for them. Note how the second line now reads deriving (Show, Read, Eq).

                                                            \n
                                                            data Size = Small | Medium | Large\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Hierarchy between type classes

                                                            \n

                                                            There can be hierarchy between type classes, meaning one requires presence of another. Common example is Ord, which is used to order data.

                                                            \n
                                                            class Eq a => Ord a where\n    compare :: a -> a -> Ordering\n    (<) :: a -> a -> Bool\n    (>=) :: a -> a -> Bool\n    (>) :: a -> a -> Bool\n    (<=) :: a -> a -> Bool\n    max :: a -> a -> a\n    min :: a -> a -> a
                                                            \n

                                                            This definition can be read as “class Ord a, where a has instance of Eq, with pile of functions as follows”. Ord has default implementation for quite many of these, in terms of others, so it’s enough to implement either compare or <=.

                                                            \n

                                                            For our Size, instance of Ord could be defined as:

                                                            \n
                                                            instance Ord Size where\n    Small <= _ = True\n    Medium <= Small = False\n    Medium <= _ = True\n    Large <= Large = True\n    Large <= _ = False
                                                            \n

                                                            Type classes allow you to write really generic code. Following is contrived example using Ord and Show:

                                                            \n
                                                            check :: (Ord a, Show a) => a -> a -> String\ncheck a b =\n    case compare a b of\n        LT ->\n            show a ++ " is smaller than " ++ show b\n        GT ->\n            show a ++ " is greater than " ++ show b\n        EQ ->\n            show a ++ " and " ++ show b ++ " are equal"
                                                            \n

                                                            Check takes two parameters that are same type and that type has to have Ord and Show instances. Ord is for ordering and Show is for turning data into string (handy for displaying it). The end result is string telling result of comparison. Below is some examples of usage. Note how our function can handle different types of data: Size, Int and [Int].

                                                            \n
                                                            > check Medium Small\n"Medium is greater than Small"\n> check Small Large\n"Small is smaller than Large"\n> check 7 3\n"7 is greater than 3"\n> check [1, 2] [1, 1, 1]\n"[1, 2] is greater than [1, 1, 1]"
                                                            \n

                                                            There are many extensions to type classes that add more behaviour. These aren’t part of standard Haskell, but can be enabled with a pragma definition or compiler flag. They can be somewhat more complicated to use, have special cases that need careful consideration, but offer interesting options.

                                                            \n

                                                            In closing

                                                            \n

                                                            I discuss and demonstrate the latest retro gadget I found at the flea market last weekend, a TASCAM Porta 02 MiniStudio 4-Track Cassette Recorder. It was in a bin full of junk—filthy, lacking its power supply, and I got it for only $5. I hacked a power supply, disassembled it completely, washed everything thoroughly, and put it back together. It worked perfectly with the exception of the pause button. This has been one of the most fun projects I can remember, especially because my daughter is into it too, and she's learning how to make multi-track recordings. I always wanted a 4-track when I was in high school but never had one. Now I do!

                                                            Pattern matching is one of those features of Haskell that immediately got me interested as it reduces amount of branching inside of functions I write. Basic idea is that if value constructors are for making data, pattern matching is for taking it apart.

                                                            \n

                                                            First example is a function that takes a Bool and returns a respective String:

                                                            \n
                                                            boolToString :: Bool -> String\nboolToString n =\n    if n\n        then "True"\n        else "False"
                                                            \n

                                                            Nothing too fancy, just an if expression inside a function. We can move that if out of there though and define exactly same functionality, but with patterns:

                                                            \n
                                                            boolToString :: Bool -> String\nboolToString True =\n    "True"\n\nboolToString False =\n    "False"
                                                            \n

                                                            There’s one definition for boolToString, but two different patterns used.

                                                            \n

                                                            Second example is bit more complex, this time we have Maybe Int that is being turned into String. Maybe has two value constructors Nothing and Just a. We have two cases for Just, specific one for when it’s Just 1 and more general one Just n that takes care of rest of the cases.

                                                            \n
                                                            isBig :: Maybe Int -> String\nisBig Nothing =\n    "Not at all"\n\nisBig (Just 1) =\n    "Just perfect"\n\nisBig (Just n) =\n    if n < 10\n        then "Just slightly"\n        else "Definitely is"
                                                            \n

                                                            Some example usage:

                                                            \n
                                                            > isBig Nothing\n"Not at all"\n> isBig $ Just 0\n"Just perfect"\n> isBig $ Just 50\n"Definitely is"
                                                            \n

                                                            Pattern matching isn’t limited to algebraic datatypes that we have been working with so far. We can do same things with records. Below is an function used to calculate total fee when cost and customer are known. Each customer can have their own discount percentage, but in addition we’re giving 10% discount to VIP customers:

                                                            \n
                                                            data Customer = Customer\n    { customerName :: String\n    , customerDiscountPct :: Double\n    , vipCustomer :: Bool\n    }\n\ntotalFee :: Double -> Customer -> Double\ntotalFee bill cust@(Customer { vipCustomer = True }) =\n    bill * 0.9 * customerDiscountPct cust\n\ntotalFee bill cust =\n    bill * customerDiscountPct cust
                                                            \n

                                                            There’s two cases of totalFee function. First one is for when passed in Customer has vipCustomer field True. Second one takes care of general case. In the first case we’re using @ to bind Customer as a whole to cust name.

                                                            \n

                                                            Lists can be matched too. The basic idea is exactly the same:

                                                            \n
                                                              \n
                                                            • (x:xs) matches a list with at least one item, x is first item, xs is rest of the items (might be an empty list)
                                                              • \n
                                                            • (x:y:_) matches two first items in a list of at least two items, x is first, y is second, _ is rest
                                                              • \n
                                                            • [] matches empty list
                                                              • \n
                                                            • (x:[]) matches list of exactly one item
                                                              • \n
                                                            \n

                                                            Underscore _ matches to everything without binding value to a name. This is useful when you don’t care about exact value, so you don’t want to give it a name. One could give it a name, but compiler will issue a warning if there are unused values in the code.

                                                            \n

                                                            Next example is recursively counting amount if items in a list using pattern matching:

                                                            \n
                                                            count :: [a] -> Int\ncount [] =\n    0\n\ncount (x:xs) =\n    1 + count xs
                                                            \n

                                                            Fibonacci series is series of number which starts with 0, 1 and then rest of the numbers are sum of two previous ones: 0, 1, 1, 2, 3, 5, 8…

                                                            \n

                                                            To calculate number in series, we can write following code (this is extremely slow way of calculating them by the way):

                                                            \n
                                                            fibonacci :: Int -> Int\nfibonacci 0 =\n    0\n\nfibonacci 1 =\n    1\n\nfibonacci n =\n    fibonacci (n - 1) + fibonacci (n - 2)
                                                            \n

                                                            Last trick in our sleeve for now is case expression. This allows us to do pattern matching inside of a function. Otherwise it works in the same way. Our fibonacci function could be defined as:

                                                            \n
                                                            fibonacci :: Int -> Int\nfibonacci n =\n    case n of\n        0 ->\n            0\n\n        1 ->\n            1\n\n        n ->\n            fibonacci (n - 1) + fibonacci (n - 2)
                                                            \n

                                                            • The cordless headphones I use are analogue cordless headphones they operate in the UHF 860 MHz RF spectrum and use Frequency modulation

                                                            • (Picture 01) shows a pair of JVC cordless headphones, these were my first pair of cordless headphones, from memory they were reasonably comfortable and lasted a reasonably long time, they eventually gave way when the strap along the top completely split if you look carefully you can see evidence of this in the picture. \"Picture-01.JPG\"

                                                            • I think my 2nd set pair of cordless headphones were made by Phillips, unfortunately I don’t have a picture of these. The headphones were too big and kept falling from my head.

I’ve lost count of how many cordless headphones I’ve owned over the years, these were also too big and regularly fell off my head, there are probably other pairs which I have forgotten about. It took a lot of trial an error to find a pair that would fit properly. \"Picture-02.JPG\"

                                                            People are what makes dynasty simulators interesting and this episode will be about them. There isn’t much code this time, mainly just how data is organized. Topic is long and split over several episodes.

                                                            \n

                                                            Some people in game are controlled by computer, while some are controlled by player. There’s no difference on what each can do in game, computer is basically just filling in for players when there aren’t enough players.

                                                            \n

                                                            There’s plenty of data about people, spread over several entities and database tables. Main one is Person, which stores name, gender, sex, date of birth and some stats (and then some more).

                                                            \n

                                                            There are lots of various ways of naming people and I chose to model three for the starters:

                                                            \n
                                                            data PersonName =\n    RegularName FirstName FamilyName (Maybe Cognomen)\n    | SimpleName FirstName (Maybe Cognomen)\n    | RegalName FirstName FamilyName RegnalNumber (Maybe Cognomen)\n    deriving (Show, Read, Eq)
                                                            \n

                                                            The higher the rank, more complicated names you tend to have (for some reason). Later on I’ll try and see if I can add more varied names, like matronyms and patronyms.

                                                            \n

                                                            Sex and gender I’m modeling with simple system of two enumerations, sex can be Female, Male or Intersex, while gender has values Man, Woman, Agender and Nonbinary. System is coarse, but should be enough to get started with the game. Later on, this can be expanded to more nuanced system.

                                                            \n

                                                            Traits are defining features of people. These include things like brave, coward, ambitious, content, honest and such. Values are binary, character either is brave or not. And character can’t be brave and coward at the same time.

                                                            \n

                                                            Relations are modeled as PersonRelation and thus stored in person_relation table:

                                                            \n
                                                            Relation json\n    originatorId PersonId\n    targetId PersonId\n    type RelationType\n    visibility RelationVisibility\n    deriving Show Read Eq
                                                            \n

                                                            I find this corner of the puzzle particular interesting. This models who is parent or child, who is friend or rival. Interconnected web created by relations isn’t completely visible to players (or any other person in game). Relations have visibility, modeled as RelationVisibility, which tells how visible it is. Public ones are known by everyone, family relations are limited to small group of people and secret relations are only known by those who are in the fold. One aspect of the game is acquiring this information.

                                                            \n

                                                            Intel is modeled as HumanIntelligence and stored in human_intelligence table:

                                                            \n
                                                            HumanIntelligence json\n    personId PersonId\n    ownerId PersonId\n    level PersonIntel\n    deriving Show Read Eq
                                                            \n

                                                            Essentially it just lists which character has what information about certain other character. So when displaying information to players, this table has to be referenced in order to know how much to reveal to them.

                                                            \n

                                                            Different types of intels are listed as PersonIntel:

                                                            \n
                                                            data PersonIntel =\n    Stats\n    | Demesne\n    | FamilyRelations\n    | SecretRelations\n    | Opinions OpinionIntel\n    | Traits\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Person related data is sent back to client in PersonReport record (I’m not copying it here as it’s relatively large). We can have a look on how one field is processed.

                                                            \n

                                                            For example, in case of traits. PersonReport has field personReportTraits :: !(Maybe [TraitReport]). Exclamation mark in the beginning of type instructs Haskell that this value should be computed immediately when record is created and not left for later. I’m doing this as I know for sure that it’ll always be used and there’s no advantage on delaying computation for the time when it might be needed.

                                                            \n

                                                            Report creating (high level):

                                                            \n
                                                            personReportTraits = if Traits `elem` targetIntel\n                        then Just $ traitReport <$> targetTraits\n                        else Nothing
                                                            \n

                                                            That first checks that Traits level of intel is available and then creates list of trait reports (one for each trait person has). These have things like trait name, description, trait type and how long the trait is valid. Having separate name and description fields makes it easier to work on client side as I don’t have to come up with descriptions there anymore. I can just use what the server sends to me and be happy.

                                                            \n

                                                            Hi to all you out there in HPR land, this is a quick show to help out with the current summer shortage of shows.

                                                            \n

                                                            So over the last few months I’ve been busy with my new Podcasting career, well it fills in the time now I’m retired. Anyway the Distro-hoppers show has been getting a regular audience and recently we decided to branch out a little and open up the review format to the audience, you can find details of how to do that on the Blog.

                                                            \n

                                                            The most recent show was a review of the new Endeavour OS which has risen from the ashes of Antergos Linux an Arch based OS. Well I decided to use this opportunity to delve into the world of Arch for the first time with Endeavour OS and I can report I was pleasantly surprised with this slick iteration of Arch. OK when you first install Endeavour all you will have is a new XFCE 4.14 DE and some basic software to get you started, you are then expected to do a little research to find out how to install other software you need to get your PC setup the way you like but all the basic information on package management is on the Endeavour OS Wiki and also on the Arch Linux Wiki.

                                                            \n

                                                            If you have thought of trying Arch Linux but would prefer to start with a running Desktop from install then Endeavour OS is definitely the place to start. I have been running it as my daily Driver for over a month and have fallen in love with it.
                                                            \nMy full review is on the Distrohoppers Blog as is a link to the Audio of the show.

                                                            The board I built which attaches to the Piface Digital board has a total of 8 LED’s. I use the 8 LED’s to display a number in binary format. In binary each LED has only two values either on or off, with 1 LED you can count to 1 with two LED’s you can count to 3. This may seem confusing if you’ve never dealt with binary before. Starting from the right each subsequent LED represents double the value of the previous one so the 1st LED has a value of 1 the 2nd LED has a value of 2, the third LED has a value of 4 and so on. See below

To load the computer instructions must be loaded in binary using flip switches and LED’s with practice it becomes second nature.

                                                            What is persistent memory?

                                                            \n

                                                            In brief, PMEM is next generation memory technology whose data transfer speed is as good as DRAM (50-300 ns, 100 times faster than SSDs) and unlike DRAM, it can even retain the data after reboots.

                                                            \n

                                                            In detail persistent memory (PMEM) is a solid-state high-performance byte-addressable memory device that resides on the memory bus. Being on the memory bus allows PMEM to have DRAM-like access to data, which means that it has nearly the same speed and latency of DRAM and the nonvolatility of NAND flash. NVDIMM (nonvolatile dual in-line memory module) and Intel 3D XPoint DIMMs (also known as Optane DC persistent memory modules) are two examples of persistent memory technologies.

                                                            \n

                                                            Persistent memory, such as Intel® Optane™ DC Persistent Memory, provides a future-proofed solution. Installed alongside traditional RAM, PMEM has many of the advantages of DRAM, including low latency access. But it comes in greater capacities. Intel® Optane™ DC, for example, will be available in 128GB, 256GB and 512GB sizes.

                                                            \n

                                                            Persistent memory in the data center allows applications to run without incurring the latency penalty of going out to storage.

                                                            The main advantages of persistent memory include:

If power is lost before the data is written to disk, you don’t lose the data because it can be recovered from NVRAM. NVRAM uses battery backup to keep data persistent. During this time it can flash the data out to a flash device that is attached directly. In most cases, NVRAM resides on the PCIe bus.

                                                            It’s no wonder that this sort of ‘in-memory’ computing has exploded in recent years. According to Gartner, 75 percent of cloud-native application development will use in-memory/PMEM computing by 2019, and by 2021, at least 25 percent of large and global organisations will adopt platforms using in-memory technologies.

                                                            \n

                                                            Two HPR hosts who live in the Edinburgh locality in Scotland met on Saturday 24th August for a chat.

                                                            \n

                                                            The hosts are:

                                                            \n\n

                                                            Some of the meeting was recorded and is presented here.

                                                            \n

                                                            Recording information

                                                            \n

                                                            We were both recording this chat. Dave was using his Zoom H2n (with the microphones in XY mode) and MrX had left his small Dictaphone-like recorder on the table.

                                                            \n

                                                            Most of the audio here was from the Zoom, but at one point it switches to MrX’s recorder for comparison. The sample is at about 18 minutes into the recording (hard to judge since an intro sequence will have been added on the HPR site). A “chirp” effect has been added at the start and end of this sample to help with identification.

                                                            \n

                                                            The Zoom track had noise reduction applied to it, using a noise sample from the start as a reference. The sample from MrX’s recorder also had noise reduction applied, and both tracks were amplified.

                                                            Computing the score is based on intelligence player has available to them. Internally we have ReportResult that tracks score, reasons for the score and confidence level about the results. It’s defined as:

When two results are combined, scores are added together, lists of reasons are concatenated and the lowest confidence level is used. This is written as:

                                                            Current system compares two lists of traits. For example, two brave characters like each other slightly better than if one of them would be coward. Comparison is done by traitPairOpinion function, which definition I’m omitting as it’s rather long and not too interesting. It’s signature is: traitPairOpinion :: TraitType -> TraitType -> Maybe (OpinionScore, OpinionReason). So, given two traits, tells how that pair affects to opinion and reasoning for it.

                                                            \n

                                                            In order to have nicer format for out data, we introduce a helper function:

                                                            \n
                                                            traitPairScore :: TraitType -> TraitType -> (OpinionScore, [OpinionReason])\ntraitPairScore a b =\n    case traitPairOpinion a b of\n            Nothing ->\n                mempty\n\n            Just (s, r) ->\n                (s, [r])
                                                            \n

                                                            This is because (OpinionScore, OpinionReason) isn’t monoid, but (OpinionScore, [OpinionReason]) is, which means we can combine them with <>.

                                                            \n

                                                            Actual score calculation based on traits, we do it like this:

                                                            \n
                                                            traitScore :: [TraitType] -> [PersonIntel] -> [TraitType] -> [PersonIntel] -> ReportResult\ntraitScore originatorTraits originatorIntel targetTraits targetIntel =\n    if (Traits `elem` originatorIntel) && (Traits `elem` targetIntel)\n        then DetailedLevel score reasons\n        else FeelingLevel score\n    where\n        (score, reasons) = mconcat $ traitPairScore <$> originatorTraits <*> targetTraits
                                                            \n

                                                            The interesting part is mconcat $ traitPairScore <$> originatorTraits <*> targetTraits. Function traitPairScore expects two TraitType values as parameters, but we’re calling it with two lists of such values. First step is to use <$> and list of values, which produces a list of partially applied functions. Second step is to use <*> to call each and every of those functions with values from second list. Result is a list of results that were obtained by calling traitPairScore with every combination of elements from two lists. Final step is to take this list of ReportResult values and combine them to single result with mconcat.

                                                            \n

                                                            Finally, based on available intel, ReportResult of correct level is created.

                                                            \n

                                                            Opinion based on relations

                                                            \n

                                                            Score based on relations is similar, but a bit convoluted (or rather, a lot more).

                                                            \n

                                                            Intel here has two dimensions. One of them is relationship visibility (is it public, family relation or secret relation), another is level of detail: BaseOpinionIntel, ReasonsForOpinions and DetailedOpinions.

                                                            \n

                                                            relationScore is the entry point for calculation:

                                                            \n
                                                            relationScore :: [PersonIntel] -> [Relation] -> ReportResult\nrelationScore intel relations =\n    mconcat $ (relReport oIntel score) <$> visibilities\n    where\n        score = mconcat $ (relationTypeScore . relationType) <$> relations\n        visibilities = mkUniq $ relationVisibility <$> relations\n        oIntel = mkUniq $ mapMaybe (\\case\n                                        Opinions x ->\n                                            Just x\n\n                                        _ ->\n                                            Nothing)\n                                   intel
                                                            \n

                                                            Code has to take into account of what level of intel we have about opinions and on what detail: oIntel. On the other hand, visibilities is unique relation visibilities that exists in relations in this particular case and score is computed based on relations.

                                                            \n

                                                            Function relReport creates final report. It takes into account on what level of intel we have, by doing: matching = safeHead $ reverse $ sort $ filter (\\x -> opinionIntelVisibility x == visibility) intel. This finds highest level intel we have about this particular relationship visibility. Based on the highest level of available intel ReportResult is created with correct confidence level. Ie. if there’s no specific intel, we get FeelingLevel report. If there’s intel about why particular person has certain opinion, we get ReasonsLevel report. Whole definition of function is below:

                                                            \n
                                                            relReport :: [OpinionIntel]\n    -> (OpinionScore, [OpinionReason])\n    -> RelationVisibility\n    -> ReportResult\nrelReport intel (score, reasons) visibility =\n    case matching of\n        Nothing ->\n            FeelingLevel score\n\n        Just (BaseOpinionIntel _) ->\n            FeelingLevel score\n\n        Just (ReasonsForOpinions _) ->\n            ReasonsLevel score reasons\n\n        Just (DetailedOpinions _) ->\n            DetailedLevel score reasons\n    where\n        matching = safeHead $ reverse $ sort $ filter (\\x -> opinionIntelVisibility x == visibility) intel
                                                            \n

                                                            Opinion report

                                                            \n

                                                            To pull all this together, we combine results of these two functions. Based on given information, it’ll compute traitsRep and relationsRep. These two are combined with <> as explained earlier in episode:

                                                            \n
                                                              \n
                                                            • scores are summed up
                                                              • \n
                                                            • reason lists are concatenated
                                                              • \n
                                                            • confidence level is lowest of two
                                                              • \n
                                                            \n
                                                            opinionReport :: [TraitType]\n    -> [PersonIntel]\n    -> [TraitType]\n    -> [PersonIntel]\n    -> [Relation]\n    -> OpinionReport\nopinionReport originatorTraits originatorIntel targetTraits targetIntel targetRelations =\n    reportResultToOpinionResult $ traitsRep <> relationsRep\n    where\n        traitsRep = traitScore originatorTraits originatorIntel targetTraits targetIntel\n        relationsRep = relationScore originatorIntel targetRelations
                                                            \n

                                                            Finally ReportResult is transformed to OpinionReport, which can be sent to client.

                                                            \n

                                                            OpinionReport has three levels:

                                                            \n
                                                              \n
                                                            • BaseOpinionReport only tells if feeling is positive, neutral or negative
                                                              • \n
                                                            • OpinionReasonReport has feeling and in addition to reasoning
                                                              • \n
                                                            • DetailedOpinionReport has exact (more or less) score and reasoning
                                                              • \n
                                                            \n
                                                            data OpinionReport =\n    BaseOpinionReport OpinionFeeling\n    | OpinionReasonReport OpinionFeeling [OpinionReason]\n    | DetailedOpinionReport OpinionScore [OpinionReason]\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Actual transformation is shown here:

                                                            \n
                                                            reportResultToOpinionResult :: ReportResult -> OpinionReport\nreportResultToOpinionResult (FeelingLevel score) =\n    BaseOpinionReport $ scoreFeeling score\n\nreportResultToOpinionResult (ReasonsLevel score reasons) =\n    OpinionReasonReport (scoreFeeling score) reasons\n\nreportResultToOpinionResult (DetailedLevel score reasons) =\n    DetailedOpinionReport (clamp (-100) 100 score) reasons
                                                            \n

                                                            Note about incorrectness

                                                            \n

                                                            Reports are based on intel and this might lead into incorrect results. In case of player’s own avatar, they have full intel (ie. they know all relations, all traits and so on.) Therefore opinion about some other person is based wholly on what we know about them.

                                                            \n

                                                            But in case of gauging somebody else’s opinion about us or person A’s opinion of person B, when A or B isn’t us, there’s chance of misjudging things. We might not know everything about them, or we might know more about A than B knows about them. In short, opinion shown for player, is just best effort guess.

                                                            In this episode I decided to take a slight diversion into networking fundamentals. As before, if you want to learn more about installing the ONICS tool suite, go back and listen to HPR 2882.

                                                            There are three key concepts to understand about modern networks. They are:

                                                            • digital - the networks carry bits and bytes (binary digits)

                                                            • packet switched - devices break data into blobs of data called "packets" and take turns sending and receiving those packets to/from other devices attached to the network

                                                            \n

                                                            One can then dump the packet by running:

                                                            \n

                                                            \n

                                                            or send the packet by running:

                                                            There are several differences between the packets that arrive at the destination machine when sending directly over the local network versus sending via an IP gateway (router). I've mentioned how the Ethernet header is different. Can you find the other differences? What causes these differences?

                                                            \n

                                                            TIP: instead of sending the pktin command to x2hpkt, send it to a file. Do this for both local network send and for sending via the router saving each to different files. Then run pdiff on the two files to highlight the differences.

The series is composed of two playtest sessions, held earlier this year. They were recorded and chopped into manageable bites, then edited down into separate episodes. The remaining episodes in this mini-series, including this one, were all from the second session.

Playtesting is not the final step, but rather, just another stage. The construction of an RPG can be convoluted, and feedback from players is absolutely vital.

I've found that the way I use Windows is not the same as most normal Windows Users. I live most of the time inside of Chrome so Windows is just another OS to get my Chrome Browser running.

You can print these off and use a Map grid tool to navigate your journey. This is kind of an analog tool but you are downloading the maps to your computer or phone. Good to have maps saved offline while you hike, that way you don't get lost.

The GitHub Page called awesome-sdn has tons of links on NOS,Controllers, Libraries, and more. I have A couple of Northbound network and Aruba switches at home to use with my SDN projects. I highly recommend you start getting familiar with network automation using ansible or other automation best practices at the least. For the more technical stuff definitely start looking at SDN.

                                                            I discuss loading Fedora on various bits of older hardware and devise a plan to turn one of those bits of older hardware into a dedicated headless audio processor using its firewire port to keep yet another older piece of hardware alive: a Yamaha GO46 audio interface.

                                                            The section of this document which lists all of the tags currently in the system has been made more accessible. If you know of a tag in the system and you want to find out how many instances there are and which shows use them you can construct a query of the form:

                                                            \n

                                                            \n

                                                            This would look for the tag 'vim' and position the page at the relevant place.

                                                            \n

                                                            If the tag you are looking for contains spaces, you need to replace them with underscores. So to look for the tag 'vietnamese stringed instruments' your query would have to be:

Height of the each block is chance of how often it will be selected. Selection is done by chopping a stick so that its length at maximum is height of the stack. Place stick next to the stack and select the block that stick reaches at.

                                                            We have list of items and associated weight, defined as Frequency a = Frequency Int a.

                                                            \n

                                                            Total is sum of all the weights and we select a random number n between 1 and total.

When picking item, if n is equal or less than weight of the first item, return that item. Otherwise, drop the first item, subtract weight of that first item from n and try again. Eventually we either arrive to item which weight is greater than n or to empty list.

                                                            Quick detour on random number generators

                                                            \n

                                                            Haskell functions are pure, meaning that with same input, you are guaranteed to get the same output (safe for some specific cases). Which makes concept of random numbers at first glance to be impossible. This is solved by passing in a random number generator, which can supply you a random value a new random number generator. Using this new random number generator to generate a value yields you a yet another value and yet another random number generator.

                                                            \n

                                                            Passing these random number generators around in code gets tedious, but there’s different solution: MonadRandom. Using it will thread along generators automatically behind the scenes, ensuring that you always have access to a fresh generator. There’s several functions that can be used to generate random values, but we’re using this one: getRandomR :: Random a => (a, a) -> m a. Given a lower and upper bound, it will return you a random value wrapped in context that carries that new random number generator.

                                                            \n

                                                            In the end, we need to take our computation (that can be complex and use multiple calls to random number generator) and turn that m a into a. This is done with runRand :: RandomGen g => Rand g a -> g -> (a, g). We give it our computation and a RandomGen g that can generate random values and receive (a, g) where a is our result and g new random number generator. In cases where we aren’t going to use the new generator, we can use evalRand :: RandomGen g => Rand g a -> g -> a, which discards it and returns just a.

                                                            First, Frequency for expressing weight of individual item. It’s parametrized, so can be used with any data.

                                                            \n
                                                            data Frequency a = Frequency Int a\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Next, determining which item to choose, based on stack and measuring stick. In case a value outside of valid range has been selected, we end up with Nothing, otherwise with Just a. First case is for empty list (either we called this originally with empty list or picked number that is greater than total sum of weights), second one either picks the first item of list or recursive calls itself removing first item.

                                                            \n
                                                            pick :: [Frequency a] -> Int -> Maybe a\npick [] _ = Nothing\n\npick (Frequency x item:xs) i\n    | i <= x = Just item\n    | otherwise = pick xs (i - x)
                                                            \n

                                                            Finally, function for calculating total of weights and choosing random number. We’re using that Rand g (Maybe a) I explained earlier. First case is for empty list again and latter case for list with at least one item.

                                                            \n
                                                            choose :: RandomGen g => [Frequency a] -> Rand g (Maybe a)\nchoose [] =\n    return Nothing\n\nchoose items = do\n    let total = sum $ fmap (\\(Frequency x _) -> x) items\n    n <- getRandomR (1, total)\n    return $ pick items n
                                                            \n

                                                            Notice how we can get random number by n <- getRandomR (1, total), without talking about generators. MonadRandom is handling generators and making sure that there’s always a fresh generator available and new generator is stored ready to be used.

                                                            \n

                                                            And that’s all the code this time (I told the amount of code is small this time).

                                                            \n

                                                            In closing

                                                            \n

                                                            This probably sounds a lot more complicated than it actually is. I arrived to the result after quite many detours, but the end result looks pretty nice.

                                                            \n

                                                            Next time we’re going to have a look where to use our choose function.

                                                            \n

                                                            I started the day in tears, still aching from losing a rare, true friend.  Then I recalled a song from Toby Keith, called “Cryin’ for Me (Wayman’s Song ) written about he loss of his close friend, Wayman Tisdale.  Toby found about his friends passing on Friday.  On Sunday Toby was driven to write the memorial song.  In it he says his tears are not for his lost friend, who is now in Heaven, but for Toby himself, and all those family, and friends, Wayman left behind.  I believe Fifty is in Heaven, with his Dad, and those who have gone before.  He will see things from the Good Seats.  He can enjoy all the Holidays, and never feel the cold.  I was driven to write like Toby, to handle my own shock and grief.  We Cry and Mourn, those left behind in the Mortal world, for our loss and pain.  Our dear One is beyond pain, perhaps for the first time in years.  He has earned his time in Grace.  He as paid as we pay now, for life beyond grief, with those who have gone ahead.   I hope my words and memories may help  the ones he left behind.  Pain is a Mortal thing. It need not be deadly, or poisonous.  Fifty’s Life is a great example of this and many other things.  I hope we can go forward, with his example helping heal our loss of him.    God Bless You, Fifty, and those you touched in turn.

                                                            Hi Everyone in HPR land this is Tony Hughes coming to you from Studio B at Woodbrooke Quaker Study Centre in Birmingham in the UK, where I am currently staying for a week of voluntary work.

                                                            The reason for this short episode is to talk about a community magazine that I have been reading since I started to use Ubuntu Linux back in 2007. Full Circle magazine actually produced a pilot issue in April of 2007 and issue one was issued in June 2007. All issues are published as a free pdf download and all the content is under a Creative Commons licence.

                                                            \n

                                                            Free Circle Magazine initially started as an Ubuntu (and official spins of Ubuntu) magazine but over the years while still being officially about Ubuntu or Linux Distributions based on Ubuntu, many of the articles are applicable to those across the Linux community.

                                                            \n

                                                            Over the years, as well as printing one off articles about individuals’ journey to using Linux, reviews and letters from readers, there have been regular series on topics such as Inkscape, Python programming, Open/LibreOffice, Virtualisation and much more.

                                                            \n

                                                            Sadly after over 12 years of producing a regular monthly magazine for the Linux community some of the regular article series are coming to an end and due to ill health at least one regular writer is not able to contribute at the moment, and this is leaving the magazine short of content and in danger of possibly coming to an end.

                                                            \n

                                                            As a podcast community that is used to the idea of crowd sourced content, many of whom are also Linux users, could I ask that some of you that have read Full Circle, but never contributed, consider sending in some content. It could be an article on how you started using Linux, about some Linux software that you think the readers may be interested in learning more about, or just a letter to Ronnie to say thanks for all his efforts putting out a magazine every month for the last 12+ years.

                                                            Like many things we often don’t miss them until they are gone, and I would hate to think that Full Circle Magazine is one of those things that I will miss in the future. I have put my money where my mouth is and in coming issues you may see me in print, talking about podcasting. You could even use any writing you do as the base for a HPR show, and achieve two goals in one go.

Playtesting is not the final step, but rather, just another stage. The construction of an RPG can be convoluted, and feedback from players is absolutely vital.

                                                            Intro

                                                            \n

                                                            Last time we built a weighted list, this time we’re using that to build markov chains. Wikipedia states that “A Markov chain is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event.” and that they’re named after the Russian mathematician Andrey Markov.

                                                            \n

                                                            Configuration

                                                            \n

                                                            We’re after generic system, hence parametrized data types.

                                                            \n

                                                            First part is Configuration a that lists possible starting elements of chain and elements that can follow a particular element.

                                                            \n
                                                            data Config a = Config\n    { configStarts :: ![Item a]\n    , configContinuations :: !(Map a [Item a])\n    } deriving (Show, Read, Eq)
                                                            \n

                                                            Second part is Item a, that just holds single item that could appear in chain and relatively frequency for its appearance.

                                                            \n
                                                            data Item a =\n    Item (Frequency (Maybe a))\n    deriving (Show, Read, Eq)
                                                            \n

                                                            We’re using Maybe a as in some cases there’s chance of element being last element in chain. Thus, Nothing will represent end of chain.

                                                            \n

                                                            In previous episode, we implemented choose, but later on I decided to rename it to chooseM. So when you see chooseM, it’s just different name for what we implemented previously.

                                                            \n

                                                            Building a chain

                                                            \n

                                                            Since building a configuration depends on the case quite a bit, we’re just going to assume that we have one at hand.

                                                            \n

                                                            Our chains are built by chainM :: (Ord a, RandomGen g) => Config a -> Rand g [a]. Given a config, it creates computation that when run will return list of a, which is our chain.

                                                            \n

                                                            Implementation is fairly straightforward:

                                                            \n
                                                            chainM config = do\n    starter <- chooseM (itemToFreq <$> configStarts config)\n    case join starter of\n        Nothing ->\n            return []\n\n        Just h -> do\n            t <- tailOfChain config h\n            return $ h : t
                                                            \n

                                                            First we select item from starting elements. In case there isn’t one, result will be a empty list. Otherwise we use tailOfChain to compute rest of the list and return a list of starter element followed by that tail.

                                                            \n

                                                            For tail we need to figure out first what possible elements there are that can follow a given element. This is done by candidates function. lookup finds a possible list of elements in configContinuations. We use itemToFreq to turn this list into frequencies. Since items might be Nothing (in case where there aren’t any suitable continuations present) and any continuation in the list might be Nothing (in case where this is possibly terminating element), we have to use (fmap . fmap) to apply itemToFreq to each possible element. Moreover, concat turns our Maybe [Frequency (Maybe a)] into [Frequency (Maybe a)], if we have Nothing at this stage, result will be an empty list [].

                                                            \n
                                                            candidates :: (Ord a) => Config a -> a -> [Frequency (Maybe a)]\ncandidates config x =\n    concat $ (fmap . fmap) itemToFreq items\n    where\n        items = lookup x (configContinuations config)
                                                            \n

                                                            That concat part could have been written as:

                                                            \n
                                                                case (fmap . fmap) itemToFreq items of\n        Nothing ->\n            []\n\n        Just x ->\n            x
                                                            \n

                                                            and the end result would be identical.

                                                            \n

                                                            Now that we know how to figure our possible continuation elements, we can implement computing tail of chain:

                                                            \n
                                                            tailOfChain :: (Ord a, RandomGen g) => Config a -> a -> Rand g [a]\ntailOfChain config c = do\n    item <- chooseM (candidates config c)\n    case join item of\n        Nothing ->\n            return []\n\n        Just x -> do\n             xs <- tailOfChain config x\n             return $ x : xs
                                                            \n

                                                            Function first select item from candidates. If there isn’t suitable item or item is Nothing, result will be an empty list. Otherwise function recurses, computes tail starting from selected element and constructs chain starting by selected item and followed by tail.

                                                            \n

                                                            join item at the start of case analysis collapses two nested Maybes together:

                                                            \n
                                                              \n
                                                            • Nothing will result Nothing (no suitable continuation)
                                                              • \n
                                                            • Just Nothing will also result Nothing (end of chain reached)
                                                              • \n
                                                            • Just a will result Just a (suitable element found)
                                                              • \n
                                                            \n

                                                            In the end we have list that is sort of like: h : chooseM (candidates config h) : chooseM (candidates config h') : chooseM (candidates config h'') : ... : []

                                                            \n

                                                            For convenience we define two other functions. First one is for when we don’t want to use Rand g a. It’s done by applying runRand function with our chainM function, config and RandomGen.

                                                            chain :: (Ord a, RandomGen g) => Config a -> g -> ([a], g)\nchain config g =\n    runRand (chainM config) g
                                                            \n

                                                            More interesting is chains which builds infinite list of chains:

                                                            \n
                                                            chains :: (Ord a, RandomGen g) => Config a -> g -> [[a]]\nchains config g =\n        c : chains config g'\n    where\n        (c, g') = chain config g
                                                            \n

                                                            This uses chain function to create starting element (which is markov chain) and new generator g'. Then it builds a list where that first chain is followed by list of chains that is created by calling chains with that new random generator. Since there’s no termination case in the function, it will compute infinitely long list of markov chains. This works because elements are computed only when needed. For all intents and purposes for program using this infinite list, items are there when needed.

                                                            \n

                                                            Closing

                                                            \n

                                                            Hardest part working with markov chains (at least in my opinion) is building suitable configuration. When you have that configuration at hand, building chains from it requires relatively small amount of code. In the next episode we’re going to use this chains for our space game.

It still wouldn't boot even with the repaired filesystem, but I was able to mount the drive and copy her files to a USB drive.

It got a lot of attention for the college students who first put it together (and remember that Facebook was originally created by a college student, Mark Zuckerberg). The four students, Ilya Zhitomirskiy, Dan Grippi, Max Salzberg, and Raphael Sofaer, were inspired by a speech Eben Moglen gave to the Internet society’s New York Chapter, where he described centralized social networks as “Spying for free”. The students chose the name Diaspora, which is a Greek word that means a “scattered or dispersed population” to reflect the idea that instead of a centralized platform, Diaspora would consist of independent nodes, called pods, each running a copy of the free software which is open source and licensed under the GNU-AGPL-3.0 license. https://www.zwilnik.com/?page_id=1032

                                                            This series is meant to give listeners some insight into the RPG construction process. Playtesting is not the final step, but rather, just another stage. The construction of an RPG can be convoluted, and feedback from players is absolutely vital.

                                                            It’s not unusual for a game master to have two sets of maps for an adventure: one is for the players, which only has the sort of information on it that their characters might reasonably have access to; the other is NOT for the players, as it shows all the special information they shouldn’t know about (at least, not all at once). This is where you’d make note of secret doors, hidden objects or enemies, and/or, as in the case of this playtest, the physical condition of the ship as it stands at the moment.

This was held at The Manchester Conference Centre during the weekend of October 19th and 20th 2019. We had an HPR table, which was manned by many HPR hosts and received many visitors. Ken recorded interviews which will be released later in November.

                                                            In the two previous episodes we built a weighted list and used that to build markov chains. This time we’re going to use them to generate some names based on examples. I’m skipping over a lot of uninteresting code in this episode, concentrating only the parts that deal with names.

                                                            \n

                                                            Person in game might hear scurrying sounds inside walls of their quarters. Then they have option of getting a cat, taming a rat or letting someone else deal with the problem. Depending on their choice, they might end up with a cat or a rat, that of course needs a name. Game offers 3 different options of names that haven’t been used before and person can always opt for completely random one.

                                                            addName function is used to add single name into config:

                                                            \n
                                                            addName :: Int -> Text -> Config Text -> Config Text\naddName n s config =\n    links pairs $\n            end elements $\n            start elements config\n    where\n        elements = chunksOf n s\n        pairs = zip elements (safeTail elements)
                                                            \n

                                                            First s (name) is split into strings of length n. These elements are then combined into pairs, where consecutive elements form a pair. Final step is to add start and ending elements into config, followed by links between elements of pairs.

                                                            \n

                                                            We can then fold a list of examples into config:

                                                            \n
                                                            nameConfig :: [Text] -> Int -> Config Text\nnameConfig xs n =\n    foldr (addName n) emptyConfig xs
                                                            \n

                                                            This starts with emptyConfig and calls addName repeatedly until all elements of list containing examples have been processed.

                                                            \n

                                                            Implementation

                                                            \n

                                                            Now that we have configuration, we can start generating names. As usual, I like to keep things specific and generate PetName instead of just Text. I happened to have list of ancient greek names at hand, so I used that. Later on we’ll have to add more cultures, like Romans, Parthians, Persians, Germans, Phoenicians and so on.

                                                            \n

                                                            General implementation of generating infinite list of strings of specific kind is shown below:

                                                            \n
                                                            names :: (RandomGen g, Eq b) => (Text -> b) -> Config Text -> g -> [b]\nnames t config g =\n    nub $ (t . toTitle . concat) <$> chains config g
                                                            \n

                                                            It’s easier to read if you start from right. chains config g generates infinite list of markov chains with given configuration. Next we create a new function (t . toTitle . concat), which uses concat to combine list of Text into single Text, toTitle to capitalize is correctly and t to transform it to something (PetName in our case). <$> is then used to apply this function to each element of our infinite list. Finally nub is used to remove duplicate entries.

                                                            \n

                                                            With names we can then define petNames:

                                                            \n
                                                            petNames :: (RandomGen g) => g -> [PetName]\npetNames =\n    names MkPetName greekNameConfig
                                                            \n

                                                            MkPetName is value constructor that turns Text into PetName (this is t used by names function).

                                                            \n

                                                            Pets

                                                            \n

                                                            Pets are currently very much work in progress. They have few attributes and there can be two different kinds of pets:

                                                            \n
                                                            Pet json\n    name PetName\n    type PetType\n    dateOfBirth StarDate\n    dateOfDeath StarDate Maybe\n    ownerId PersonId\n    deriving Show Read Eq
                                                            \n
                                                            data PetType\n    = Cat\n    | Rat\n    deriving (Show, Read, Eq, Ord, Enum, Bounded)
                                                            \n

                                                            The actual beef is namingPetEvent function. When applied with Entity Person, Entity Pet and StarDate, it will create News that can be saved into database and later on showed to player. While the code is shown below, I’m not going to go over it line by line:

                                                            \n
                                                            namingPetEvent :: (PersistQueryRead backend, MonadIO m,\n    BaseBackend backend ~ SqlBackend) =>\n    Entity Person -> Entity Pet -> StarDate -> ReaderT backend m News\nnamingPetEvent personE petE date = do\n    pets <- selectList [ PetOwnerId ==. (entityKey personE)\n                       , PetDateOfDeath ==. Nothing\n                       ] []\n    let names = (petName . entityVal) <$> pets\n    g <- liftIO getStdGen\n    let availableNames = take 3 $ filter (\\x -> not (x `elem` names)) $ petNames g\n    let content = NamingPet (NamingPetEvent { namingPetEventPersonId = entityKey personE\n                                            , namingPetEventPetId = entityKey petE\n                                            , namingPetEventPetType = (petType . entityVal) petE\n                                            , namingPetEventDate = date\n                                            , namingPetNameOptions = availableNames\n                                            })\n                            [] Nothing\n    return $ mkPersonalSpecialNews date (entityKey personE) content
                                                            \n

                                                            General idea is to use selectList to load living pets of given person and then extract their names. With random generator g, we create a infinite list of PetNames, remove already used names from it and take 3 first ones. These names are then used to create NamingPetEvent.

                                                            \n

                                                            In closing

                                                            \n

                                                            Names are probably one of the most common applications of markov chains in games. Same technique can be used to generate nonsense books and articles that look realistic on a glance.

                                                            Financial privacy is critical for adoption of cryptocurrency as a means of exchange. Individuals worry about employers monitoring their spending details, insurers increasing rates based on purchases and landlords raising rents when they get a promotion. Businesses can only operate using cryptocurrency if they can prevent disclosure of vendor payments, rates paid to suppliers, payroll details, and so on. At the same time, they need to selectively disclose financial data to governments and might need to demonstrate compliance in some industries.

It offers the strongest privacy protection assurances around, through a variety of clever tricks. For one thing, transaction history is not recorded, which also results in a smaller blockchain. There are no addresses and no transaction amounts are recorded.

                                                            I have liked writing automated tests for a long time, so it’s not a surprise that I end up writing them in Haskell too. This is very broad topic, so this episode only scratches the surface.

                                                            \n

                                                            \n

                                                            HSpec is testing framework that automatically detects tests, like most of the modern systems. It supports hierarchies, so one can organize tests by feature for example.

                                                            \n
                                                            spec :: Spec\nspec = do\n    describe "Very important feature" $ do\n        it "Execution should be error free" $ do\n            ...\n\n        it "Flux capacitors can be charged" $ do\n            ...\n\n    describe "Somewhat less important feature" $ do\n        ...
                                                            \n

                                                            Unit test

                                                            \n

                                                            Unit test tests a single case with fixed set of inputs. With pure functions these are a pleasure to write as they’re really just data in, data out, verify results. Below is two examples:

                                                            \n
                                                            spec :: Spec\nspec = do\n    describe "Markov chain configuration" $ do\n        it "Adding new starting element to empty configuration creates item with frequency of 1" $ do\n            let config = addStart ("AA" :: DT.Text) emptyConfig\n            config ^? (configStartsL . _head . itemFreqL) `shouldBe` Just 1\n            config ^? (configStartsL . _head . itemItemL . _Just) `shouldBe` Just "AA"\n\n        it "Adding same element twice to empty configuration creates item with frequency of 2" $ do\n            let config = addStart "AA" $\n                         addStart ("AA" :: DT.Text) emptyConfig\n            config ^? (configStartsL . _head . itemFreqL) `shouldBe` Just 2\n            config ^? (configStartsL . _head . itemItemL . _Just) `shouldBe` Just "AA"
                                                            \n

                                                            Both are for testing configuring markov chains. First one checks that adding a starting element in empty configuration results correct item with correct weight being added. Second checks that adding same starting element twice results weight of 2.

                                                            \n

                                                            Both tests use lenses for reading nested data structure. Episode doesn’t cover them much at all, as it’s enough to know that (configStartsL . _head . itemFreqL) focuses on starting elements of configuration, selects first item of the list and then selects frequency of that item. Lenses can also be used for modifying data and they don’t have to focus on only one element.

                                                            \n

                                                            Unit tests are easy enough to write, they verify single thing about the unit being tested and are usually super fast to run and not error prone.

                                                            Property based tests are used to check that a certain property holds with randomly generated input parameters. I’m using HSpec as testing framework and QuickCheck as tool for generating test data:

                                                            spec :: Spec\nspec = do\n    describe "planets" $ do\n        describe "food" $ do\n            it "food requirement for positive amount of population is more than zero" $ do\n                forAll positivePopulation $ \\x -> foodRequirement x  > RawResource 0\n\n            it "food base production for farms is equal or greater than their amount" $ do\n                forAll someFarms $ \\x -> (sum (fmap foodBaseProduction x)) > (RawResource $ length x)
                                                            \n

                                                            Above we have two tests. First one checks that with any non-zero population, foodRequirement is greater than 0. Second one check that with any positive amount of farm, foodBaseProduction is greater than amount of the farms.

                                                            \n

                                                            positivePopulation is Generator, that is used by QuickCheck to generate random data for testing. Its definition is shown below:

                                                            \n
                                                            singlePopulation :: Gen PlanetPopulation\nsinglePopulation = do\n    let aPlanetId = toSqlKey 0\n    let aRaceId = toSqlKey 0\n    aPopulation <- arbitrary `suchThat` \\x -> x > 0\n    return $ PlanetPopulation aPlanetId aRaceId aPopulation\n\npositivePopulation :: Gen [PlanetPopulation]\npositivePopulation = do\n    k <- arbitrary `suchThat` \\x -> x > 0\n    vectorOf k singlePopulation
                                                            \n

                                                            Generated data can be really simple or very complex. Generating complex data is often convenient to break into smaller steps and write generators for them.

                                                            \n

                                                            Property based tests are somewhat harder to write than unit tests, but they can potentially cover edge cases that might otherwise not been discovered.

                                                            \n

                                                            Working with database

                                                            \n

                                                            All tests shown so far have been testing pure code, that is, code that is data in, data out. When database is introduced, things get more complicated. Suddenly there’s much more possibilities for errors. Below is an example of such a test:

                                                            \n
                                                            spec :: Spec\nspec = withApp $ do\n\n    describe "Status handling"  $ do\n        describe "Planet statuses"  $ do\n            it "Expired planet statuses are removed and news created" $ do\n\n                sId <- runDB $ insert $ StarSystem\n                        { starSystemName = "Aldebaraan"\n                        , starSystemCoordX = 10\n                        , starSystemCoordY = 20\n                        , starSystemRulerId = Nothing\n                        }\n\n                fId <- runDB $ insert $ Faction\n                        { factionName = "Star lords"\n                        , factionHomeSystem = sId\n                        , factionBiologicals = 10\n                        , factionMechanicals = 10\n                        , factionChemicals = 10\n                        }\n\n                pId1 <- runDB $ insert $ Planet\n                        { planetName = "New Earth"\n                        , planetPosition = 3\n                        , planetStarSystemId = sId\n                        , planetOwnerId = Just fId\n                        , planetGravity = 1.0\n                        , planetRulerId = Nothing\n                        }\n\n                _ <- runDB $ insert $ PlanetStatus\n                        { planetStatusPlanetId = pId1\n                        , planetStatusStatus = GoodHarvest\n                        , planetStatusExpiration = Just 20201\n                        }\n\n                let status = Simulation 20201\n                _ <- runDB $ insert status\n\n                news <- runDB $ removeExpiredStatuses (simulationCurrentTime status)\n\n                statuses <- runDB $ selectList [ PlanetStatusPlanetId ==. pId1 ] []\n                loadedNews <- runDB $ selectList [] [ Asc NewsDate ]\n\n                liftIO $ statuses `shouldSatisfy` (\\x -> length x == 0)\n                liftIO $ news `shouldSatisfy` (\\x -> length x == 1)\n                liftIO $ loadedNews `shouldSatisfy` (\\x -> length x == 1)
                                                            \n

                                                            There’s a lot more code that had to be written for this test and majority of it is for setting up database state. The test if for ensuring that when good harvest boost expires, it is removed from database and respective news article is created.

                                                            \n

                                                            These kinds of tests have a lot more code and are much more slower to run because of the communication with a database. There’s also more cases where something can go wrong. But in the end, these kinds of tests are needed if one wants to verify that interaction with database is working as planned.

                                                            \n

                                                            Testing API

                                                            \n

                                                            Last example is about testing REST API. There are two tests, where the first one is checking that proper access control is in place and second one checks that pending messages are correctly retrieved.

                                                            \n
                                                            spec :: Spec\nspec = withApp $ do\n    describe "Message handling" $ do\n        it "unauthenticated user can't access messages" $ do\n            _ <- get ApiMessageR\n            statusIs 401\n\n        it "pending messages are loaded" $ do\n            (pId, fId) <- setupPerson\n            _ <- runDB $ insert $ researchCompleted 25250 fId HighSensitivitySensors\n            user <- createUser "Pete" (Just pId)\n            authenticateAs user\n            _ <- get ApiMessageR\n            resp <- getResponse\n            let jsonM = join (decode <$> simpleBody <$> resp) :: Maybe Value\n\n            assertEq "message tag"\n                     (jsonM ^? (_Just . _Array . _head . key "tag" . _String))\n                     (Just "ResearchCompleted")\n            assertEq "star date"\n                     (jsonM ^? (_Just . _Array . _head . key "starDate" . _Integer))\n                     (Just 25250)\n            assertEq "technology"\n                     (jsonM ^? (_Just . _Array . _head . key "contents" . key "Technology" . _String))\n                     (Just "HighSensitivitySensors")\n\n            statusIs 200
                                                            \n

                                                            Here extra complication is created by the fact that many features of the system are behind authentication and authorization. Luckily Yesod comes with helper function authenticateAs, that allows code to authenticate when system is running in development mode.

                                                            \n

                                                            These test are even slower than any of the previous ones, but on the other hand, they test whole chain from user interaction to database and back.

                                                            \n

                                                            There’s lots of things that I couldn’t cover in such a short time, like various types of tests: UI testing, performance testing, security testing, long running testing…, the list goes on and on. But hopefully this episode gave you ideas what kinds of tests one can write and how to get started doing so using Haskell.

That may have seemed a bit dry, so let’s look at this case study to put some flesh on those dry bones. Failing to manage your security risks properly can have significant consequences.

                                                            In this episode, I talk about different techniques that we can use to predict the outcome of some question depending on input features.

                                                            \n

                                                            The different techniques I will go through are the ZeroR and OneR that will create a baseline for the rest of the methods.

                                                            \n

                                                            Next up, we have the Naive Bayes classifier that is simple but powerful for some applications.

                                                            \n

                                                            Nearest neighbor and Decision trees are next up that requires more training but is very efficient when you infer results.

                                                            \n

                                                            Multi-layer perceptron (MLP) is the first technique that is close to the ones we usually see in Machine Learning frameworks used today. But it is just a precursor to Convolutional Neural Network (CNN) because of the size requirements. MLPs have the same size for all the hidden layers, which makes it unfeasible for larger networks.

                                                            \n

                                                            CNNs, on the other hand, uses subsampling that will shrink the layer maps to reduce the size of the network without reducing the accuracy of the predictions.

                                                            With small programs it’s easy enough to have all code in single file. But as the program grows, you eventually want to organize things into separate files. In this episode I’ll talk a bit how to define modules and how to use them.

                                                            \n

                                                            Defining

                                                            \n

                                                            Each module is defined in separate file. In our example, we have file called multiplexer.hs, which contains our module definition.

                                                            \n

                                                            At the beginning of the file, we have following:

                                                            \n
                                                            module Multiplexer (mix, match, Plexer, Scooper(..))\n  where\n  ....
                                                            \n

                                                            We’re omitting actual function and type definitions as they aren’t important to this episode. In any case, there’s two functions: mix and match and two types: Plexer and Scooper that module exports (that is, these are available outside of the module). Plexer is imported as a type only and Scooper with field accessors or value constructors depending if it’s a record or algebraic datatype.

                                                            \n

                                                            Using modules

                                                            \n

                                                            In order to be able to use identifiers defined in separate module, we have to import them into our current one. In our imaginary program, we have main.hs that defines entry point for our program and we would like to import the definitions from Multiplexer module.

                                                            \n

                                                            Easiest one is to just have import Multiplexer at the start of the main. This brings all exported identifiers from Multiplexer and we can then use them. Both qualified and unqualified names are imported. Qualified means name is prepended with module name: Multiplexer.mix instead of just mix.

                                                            \n

                                                            If we want, we can specify what exactly should be imported: import Multiplexer (mix, match). This causes only functions mix and match be imported, while Plexer and Scooper are unavailable for us. Again, both qualified and unqualified names are imported.

                                                            \n

                                                            In case we want only qualified names, we’ll write import qualified Multiplexer. After this mix isn’t available, but Multiplexer.mix is (and all the other identifiers exported by Multiplexer).

                                                            \n

                                                            Sometimes module name is long and tedious to repeat when using qualified names. In these cases, renaming module while importing is a good option. This can be done by writing import Multiplexer as M. After this, instead of Multiplexer.mix you write M.mix.

                                                            \n

                                                            Final thing I’m going to mention is importing everything else except specified identifiers. This is done by writing import Multiplexer hiding (mix). This imports everything exported by Multiplexer, except mix.

                                                            \n

                                                            Summary

                                                            \n

                                                            There are many ways of importing and they can be mixed. Here’s a list of them:

                                                            \n

                                                            In short:

                                                            Prelude

                                                            \n

                                                            Prelude is base module containing lots of helpful types and functions, which is automatically imported by every module. If this is not what you want, there’s two options. First one is to use pragma at start of the file: {-# LANGUAGE NoImplicitPrelude #-}, which causes Prelude not to be imported. Another one is to manually import Prelude, which turns of automatic import: import qualified Prelude as P.

                                                            \n

                                                            When system grows, it’s helpful to break it into more manageable pieces. For this we use modules. import is used to bring identifiers from other modules into current one.

In fact I never wanted to wear any ties until I got my first bolo tie, which was sufficiently different from everyone else and easy enough to put on that I decided I could wear bolo ties. I've built a collection of about a dozen of these and they always get positive comments, especially the ones made from recycled circuit boards. Recently I've expanded my horizons to include bowties, which have a more formal appearance and the added nerd factor of being difficult to tie for most people. In this episode I talk about my ties.

                                                            Hello, good people of Hacker Public Radio, my name is Paul Quirk and this is my very first ever podcast. I would like to give credit Klaatu of Gnu World Order for making me aware of Hacker Public Radio, which I’ve been a listener of for the past year. As we near the holiday season of the winter solstice, I decided to give back to the open source community with this gift of a mini series of podcasts about the World of Commodore from December 7, 2019.

                                                            \n

                                                            The World of Commodore is an annual computer expo dedicated to Commodore computers that is normally held on the first Saturday of December in the city of Mississauga, Ontario. It started off back in 1983 by Commodore Canada as a trade show where Commodore and related vendors could showcase their latest products for the holiday season. As a Commodore computer nerd kid of the 1980’s living within an hour’s drive of Mississauga, this was an event I always looked forward to with excitement. For me, this was bigger and better than Santa Claus. Commodore went bankrupt in 1994, but a decade later, the show was revived by the Toronto PET user’s group, or TPUG, one of the world’s oldest computer user groups of which I am a member. Today’s World of Commodore is very different from the expo’s of the 1980’s, and has transformed into an event where hackers from around the world gather together to share ideas and show off their own discoveries and products, both open source and commercial.

                                                            \n

                                                            Since many listeners and contributors of Hacker Public Radio got started with a Commodore computer at some time, and since this event has grown beyond Commodore products and into open source hardware and software, I thought this event would be of great interest to this community, and it is my hope that many of you listeners might join us at next year’s World of Commodore.

                                                            I have decided to create a miniseries of podcasts of this event which I will release on a weekly schedule. In this first episode, I walk around the trade show floor and interview various exhibitors, vendors, and members of TPUG. As there is a visual element to this podcast, I have posted pictures of the exhibits in my personal non-commercial blog at pquirk.com, which I encourage you to visit in order to get the full experience. And so, with no further ado, let’s all go to the wonderful world of Commodore.

                                                            \n

                                                            In the last part of my story (show 1811 in 2015) I told you about some of my experiences at the University of Manchester as a postgraduate student from around 1973.

                                                            \n

                                                            Today I want to talk a little more about my time in Manchester and mention some of the things I did that may be of interest to Hackers!

                                                            \n

                                                            Researching for the episode

                                                            \n

                                                            As I have been researching for this HPR episode I realise how long ago some of these events were - in Internet years particularly. In many cases I could find no online records of places, equipment or people. This seems to be because any records there might be are on paper and have never made it online. I contacted a company that made some of the laboratory equipment I used that I thought might be of interest, and the person I contacted said that although he remembered what I was referring to the company had kept no records of it and had had to discontinue it due to modern safety concerns.

                                                            \n

                                                            I find this somewhat dispiriting and it makes me feel very very old!

                                                            \n

                                                            Every spaceship in game needs a crew to operate it. Smaller ships with fewer components require less crew than huge ones with lots of components.

                                                            \n

                                                            Types

                                                            \n

                                                            Unit stats lists amount of crew required to operate a spaceship and if they need sleeping quarters.

                                                            \n
                                                            data UnitStats = UnitStats\n    { unitStatsMinimumCrew :: ![CrewRequirement]\n    , unitStatsNominalCrew :: ![CrewRequirement]\n    , unitStatsCrewSpace :: !TotalCrewSpace\n    , unitStatsCrewSpaceRequired :: !CrewSpaceReq\n    } deriving (Show, Read, Eq)
                                                            \n

                                                            Different positions a crew can have is an enumeration:

                                                            \n
                                                            data CrewPosition =\n    Commander\n    | Navigator\n    | Signaler\n    | SensorOperator\n    | Gunner\n    | Doctor\n    | Nurse\n    | Driver\n    | Helmsman\n    | Artificer\n    | Crew\n    | Passenger\n    deriving (Show, Read, Eq, Enum, Bounded)\nderivePersistField "CrewPosition"
                                                            \n

                                                            Rank of a crew member isn’t a military rank, but rather their position in ship’s internal hierarchy:

                                                            \n
                                                            data CrewRank =\n    SecondClass\n    | FirstClass\n    | Senior\n    | Chief\n    deriving (Show, Read, Eq, Enum, Bounded)\nderivePersistField "CrewRank"
                                                            \n

                                                            Amount of crew is newtype that helps me not to mix different types of numbers with each other.

                                                            \n
                                                            newtype CrewAmount = CrewAmount { unCrewAmount :: Int }\n    deriving (Show, Read, Eq, Ord, Num)
                                                            \n

                                                            Total crew space of a ship is divided to three different types: steerage, standard and luxury.

                                                            \n
                                                            data TotalCrewSpace = TotalCrewSpace\n    { totalCrewSpaceSteerage :: !(CrewSpace SteerageQuarters)\n    , totalCrewSpaceStandard :: !(CrewSpace StandardQuarters)\n    , totalCrewSpaceLuxury :: !(CrewSpace LuxuryQuarters)\n    } deriving (Show, Read, Eq)
                                                            \n

                                                            Again, crew space is newtype so I don’t mix different types of numbers with each other.

                                                            \n
                                                            data CrewSpace a =\n    CrewSpace { unCrewSpace :: CrewAmount }\n    deriving (Show, Read, Eq)
                                                            \n

                                                            I could have modeled fact that vehicle might need crew space with Bool, but having a descriptive name and type is more to my liking.

                                                            \n
                                                            data CrewSpaceReq =\n    CrewSpaceRequired\n    | CrewSpaceOptional\n    deriving (Show, Read, Eq)\nderivePersistField "CrewSpaceReq"
                                                            \n

                                                            The fact that single person could manage multiple components is reflected by ComponentCrewReq having Double instead of Integer

                                                            \n
                                                            -- | Crew requirements for a component\ndata ComponentCrewReq =\n    ComponentCrewReq CrewPosition Double\n    deriving (Show, Read, Eq)
                                                            \n

                                                            In closing

                                                            \n

                                                            If you have questions, comments or feedback, easiest way to catch me nowdays is by email or in fediverse where I’m Tuula@mastodon.social

The hill close by is the location of the Midlothian Snowsports Centre, an artificial Ski Slope which is very popular in the region for recreation and training.

It’s ‘simple’ in the sense that it’s easier to use than ffmpeg/avconv or VLC, because it has a straightforward user interface.

                                                            Overview

                                                            \n

                                                            I recorded the audio for the show I did with MrX in late 2019: “hpr2972 :: The foot of the ski slope”. I was using my Zoom H2n recorder in my car, on a small tripod placed on the dashboard. Something about this setup caused the result to be very boomy and (to me) unpleasant to listen to. This episode is about what I did for a cure, after some research.

                                                            \n

                                                            I have also been using the ‘Truncate Silence’ effect in Audacity incorrectly in the past, and I used the opportunity to learn how to do a better job with it.

                                                            \n

                                                            Now, I am well aware that there are some skilled and experienced Audio Engineers out there in HPR-land. I am certainly not one of these, though I quite enjoy fiddling with audio to make it sound better. I’d like to make two requests:

                                                            \n
                                                              \n
                                                            1. If I didn’t do a good job, please tell me what I did wrong here, and how I should have done it.
                                                              2. \n
                                                            2. Think about doing a show (or shows) on HPR about how to deal with common audio problems. For example: how to remove a mains hum, the use of compression and normalisation.
                                                              3. \n
                                                            \n

                                                            FOSDEM is the biggest Free and Open Source conference in the world and on its 20th anniversary I decided to attend for the first time. By a good turn of fate, and some well-judged pitching, Ken Fallon secured a stand for the Free Culture Podcasts project which is an umbrella group that covers HPR, many of the shows on The Other Side Network and many more excellent podcasts that are released under creative commons licenses.

I was surprised to find that relatively few visitors to our stand had heard of HPR, which we quickly rectified of course, and I give a brief summary of the feedback we received. Also mentioned in this show, but not actually appearing, are my co-conspirators at FOSDEM, Ken, Beni, JWP as well as Dave Morriss who unfortunately wasn't able to join us in person but was very much there in spirit.

                                                            \n

                                                            You will probably have seen references to The Environment in various contexts relating to shells, shell scripts, scripts in other languages and compiled programs.

                                                            \n

                                                            In Unix and Unix-like operating systems an environment is maintained by the shell, and we will be looking at how Bash deals with this in this episode. When a script, program or subprocess is invoked it is given an array of strings called the environment. This is a list of name-value pairs, of the form name=value.

                                                            \n

                                                            Using the environment

                                                            \n

                                                            The environment is used to convey various pieces of information to the executing script or program. For example, two standard variables provided by the shell are 'HOME', which is set to the current user’s home directory and 'PWD, set to the current working directory. The shell user can set, change, remove and view environment variables for their own purposes as we will see in this episode. The Bash shell itself creates and in some cases manages environment variables.

                                                            \n

                                                            The environment contains global data which is passed down to subprocesses (child processes) by copying. However, it is not possible for a subprocess to pass information back to the superior (parent) process.

                                                            \n

                                                            Viewing the environment

                                                            \n

                                                            You can view the environment in a number of ways.

                                                            \n
                                                              \n

                                                            • From the command line the command printenv can do this (this is usually but not always a stand-alone command: it’s /usr/bin/printenv on my Debian system). We will look at this command later.

                                                              • \n

                                                            • The command env without any arguments does the same thing as printenv without arguments. This is actually a tool to run a program in a modified environment which we will look at later. The environment printing capability can be regarded as more of a bonus feature.

                                                              • \n

                                                            • Scripting languages like awk (as well as Python and Perl, to name just a few) can view and manipulate the environment.

                                                              • \n

                                                            • Compiled languages such as C can do this too of course.

                                                              • \n

                                                            • There are other commands that will show the environment, and we will look at some of these briefly.

                                                              • \n
                                                            \n

                                                            Changing variables in the environment

                                                            \n

                                                            The variables in the environment are not significantly different from the shell parameters we have seen throughout this Bash Tips series. The only difference is that they are marked for export to commands and sub-shells. You will often see variables (or parameters) in the environment referred to as environment variables. The Bash manual makes a distinction between ordinary parameters (variables) and environment variables, but many other sources are less precise about this in my experience.

                                                            \n

                                                            The standard variables in the environment have upper-case names (HOME, SHELL, PWD, etc), but there is no reason why a variable you create should not be in lower or mixed case. In fact, the Bash manual suggests that you should avoid using all upper-case names so as not to clash with Bash’s variables.

                                                            \n

                                                            Variables can be created and changed a number of ways.

                                                            In this episode I talk about how I used a Raspberry Pi to create a streaming radio device to feed my pillow speaker. This is something I used to do with clock radios and later a satellite radio, but in an effort to decrease monthly subscription costs for services I did not use optimally, I discontinued my satellite radio subscription about a year ago. This new free solution is an excellent substitute for Satellite Radio so far, since I was mostly listening to this same channel on the Sat Radio but paying about $12 a month for the privilege. The device I’m using is a Raspberry Pi 2 Model B with Ubuntu Server. My barrier to this project in the past was not being able to find the URL for the stream I wanted but I discovered you can find it easily if you use Firefox with Video Download Helper to reveal the URL on a page with media playing (in this case it’s from TuneIn):

                                                            \n\n

                                                            Strip off everything after the 48 to get raw URL:

                                                            Command to play stream with mpg123 on the Pi. Using the -q option to suppress output:

                                                            \n\n
                                                            mpg123-pulse -q https://XX.XXX.XXX.XXX/radio-stationmp3-48 &\n
                                                            \n\n

                                                            Once I figure out the command that plays the stream I want, I save the command as an executable script in /home/$user/bin.

                                                            \n\n

                                                            \n\n

                                                            To start playing a stream you first have to SSH into the RasPi. This is easy from a laptop using any terminal emulator. I use pubkey auth so I don’t have to type a password every time. On my phone I use ConnectBot. Once I’m into the Pi I run the radio commands from CLI like espn or kmfa or krvs. To stop playback I kill the process with pkill mpg. I have a 3.5mm audio splitter Plugged into the headphone jack of the USB audio interface. In one side of the splitter I’ve got an old pair of earbuds where one side didn’t work, with the working earbud under my pillow. That’s my pillow speaker. On the other side of the splitter I put the audio cable for an FM transmitter, so that I can use an FM radio to listen to the stream while I’m walking around the house.

                                                            For start, I added interface for viewing, modifying and creating new people. It has three HTTP endpoints that are defined below. In this episode, I’ll concentrate on creating a new person and especially making sure that parameters used are valid.

                                                            Types and parsing

                                                            \n

                                                            There are two important approaches on making sure that data is valid. Making illegal state unpresentable and parsing instead of validation.

                                                            \n

                                                            If it’s impossible to create invalid data, you don’t have to validate it. Instead of using Integer and checking that given parameter is 0 or more, you should use Natural. Since Natural can’t have negative values, you don’t have to validate it. Similarly, instead of using a list, you could use NonEmpty to make sure that there’s at least one element present in the collection.

                                                            \n

                                                            Parse, don’t validate is similar approach. Instead of having a lax parser and then validating the result, parser should reject data that doesn’t make sense. By selecting suitable datatypes to represent data in the system, simply parsing incoming message is sometimes enough to validate it at the same time.

                                                            \n

                                                            Person creation

                                                            \n

                                                            Function in charge of generating a new person has signature of generatePersonM :: RandomGen g => StarDate -> PersonOptions -> Rand g Person. Given a current StarDate and PersonOptions describing what kind of person is needed, it will return a computation that can be executed to generate a random person.

                                                            \n

                                                            PersonOptions is very barebones. There’s only one field to tell what kind of age the person should have and even that is an optional field.

                                                            \n
                                                            data PersonOptions = PersonOptions\n    { personOptionsAge :: Maybe AgeOptions\n    } deriving (Show, Read, Eq)
                                                            \n

                                                            AgeOptions has two possibilities. AgeBracket describes case where age should be inside of given range. ExactAge specifies exactly what age should be.

                                                            \n
                                                            data AgeOptions =\n    AgeBracket Age Age\n    | ExactAge Age\n    deriving (Show, Read, Eq)
                                                            \n

                                                            Age is newtype wrapping Natural, thus Age can never be less than zero.

                                                            \n
                                                            newtype Age = Age { unAge :: Natural }\n    deriving (Show, Read, Eq, Num, Ord)
                                                            \n

                                                            Hand written FromJSON instance takes care of rejecting numbers that aren’t integers and at least zero. One could skip the checks here and parsed Age still couldn’t be negative. Advantage of explicit checks is that we get much nicer error message instead of just annoying runtime exception.

                                                            \n
                                                            instance FromJSON Age where\n    parseJSON =\n        withScientific "age"\n            (\\x -> case toBoundedInteger x of\n                Nothing ->\n                    mempty\n\n                Just n ->\n                    if n >= 0 then\n                        return $ Age $ fromIntegral (n :: Int)\n\n                    else\n                        mempty)
                                                            \n

                                                            So, when creating a new person, you can have:

                                                            \n

                                                            • age is always integer that is 0 or more

                                                            \n

                                                            There’s still possibility of error. Nothing ensure that age bracket makes sense. It could be AgeBracket (Age 10) (Age 5) (bracket from 10 to 5). We need to add a bit of validation.

                                                            \n

                                                            Data.Validation is “a data-type like Either but with an accumulating Applicative”. What this means to me is that I can validate multiple aspects and collect errors in a list. It’s handy for getting all the problems at once, instead of having to fix them one by one and retry after each fix.

                                                            \n

                                                            Our validation function has signature validateAddPerson :: PersonOptions -> Validation [ErrorCode] PersonOptions. Given PersonOptions, it will give list of ErrorCode and original PersonOptions. Multiple validation functions can be combined for more complex validations.

                                                            \n

                                                            In our example validateAgeOptions validates only age related options of the data. validateAddPerson is supposed to validate whole data, but currently it just delegates to validateAgeOptions. In the future, we can add more validations by adding more functions and chaining them with <* operator.

                                                            \n
                                                            validateAddPerson :: PersonOptions -> Validation [ErrorCode] PersonOptions\nvalidateAddPerson opt =\n        pure opt\n            <* validateAgeOptions opt\n\nvalidateAgeOptions :: PersonOptions -> Validation [ErrorCode] PersonOptions\nvalidateAgeOptions opt =\n    case personOptionsAge opt of\n        Nothing ->\n            _Success # opt\n\n        Just (AgeBracket a b) ->\n            if a <= b\n                then _Success # opt\n                else _Failure # [ AgeBracketStartIsGreaterThanEnd ]\n\n        Just (ExactAge _) ->\n            _Success # opt
                                                            \n

                                                            Putting it all together

                                                            \n

                                                            Function that handles POST message and creates a new person is shown below:

                                                            \n
                                                            postAdminApiAddPersonR :: Handler Value\npostAdminApiAddPersonR = do\n    _ <- apiRequireAdmin\n    msg <- requireJsonBody\n    date <- runDB $ starDate\n    _ <- raiseIfFailure $ validateAddPerson msg\n    g <- liftIO newStdGen\n    let person = evalRand (generatePersonM date msg) g\n    pId <- runDB $ insert person\n    returnJson (Entity pId person)
                                                            \n

                                                            It does several things: - check that current user is admin - get json content and parse it to PersonOptions - get current star date from database - validate PersonOptions and return error if validation fails - get new random number generator - generate new person - insert it into database - return tuple of (PersonId, Person)

                                                            \n

                                                            Closing

                                                            \n

                                                            Types should represent only valid states. By having invalid state unpresentable, we can avoid many errors. Likewise, parsing should reject invalid data. This usually follows from having invalid states being unpresentable (you can’t parse invalid message to invalid data if you don’t have way to represent that invalid data).

The domain-specific language means that Apache Camel can support type-safe smart completion of routing rules in an integrated development environment using regular Java code without large amounts of XML configuration files, though XML configuration inside Spring Framework is also supported. Camel is often used with Apache ServiceMix, Apache ActiveMQ and Apache CXF in service-oriented architecture projects. \n

                                                            Entanglement and superposition: Entanglement lets us do unusual, head-scratching kinds of things like teleportation. Superposition lets us harness the almost unimaginable potential of quantum mechanics to do things that conventional computers can never do.

                                                            How can you ever explain that in a podcast?

                                                            To really understand the details, you must have math, but math and audio formats are not so compatible. So I use analogies, and throw in some pithy quotes from Einstein and hope that does the trick.

                                                            Lots of work going on to build quantum processors (QPUs) that use quantum memory and, get this, will at some point actually do error correction. There are programming frameworks and rudimentary compilers to compile down python code all the way down to microwave pulses and laser pulses and there is control machinery to gather back the signals and interpret them to ones and zeros. Quantum computers will be securely networked using quantum protocols and we’ll all live happily ever after in a quantum computing world.

                                                            This is basically a transcript of the post I wrote on the subject which I host here It has a bit more than what I talked about

                                                            \n

                                                            Join in Haskell

                                                            \n

                                                            join is a monadic operation, instead of working only on lists, it works on monads and has the signature:

                                                            \n
                                                               join :: Monad m => m ( m a ) -> (m a)\n
                                                            \n

                                                            In effect it joins or merges two successive monad applications into a single monad application. But join is not part of the canonical monad definition, which is given by:

                                                            \n
                                                               return ::  Monad m => a -> m a` ; and`\n   (>>=) :: Monad m => m a -> ( a -> m b ) -> m b\n
                                                            \n

                                                            A good or rather trivial way to think of the relationship between return join and (>>=) is that in essence, since each monad is a functor, then what (>>=) does is that it maps the second argument over the first argument, and then uses join to merge the two applications of the monad constructor, i.e.:

                                                            \n
                                                              (x >>= f) = join $ fmap f x\n
                                                            \n

                                                            However, join needs to be constructed from return and (>>=). The naive solution is that we want to trick (>>=) to let us apply a function that does not pile up yet another m onto our initial type m (m a) and surprisingly, this will actually work if we let

                                                            \n
                                                               join x = (x >>= id)\n
                                                            \n

                                                            Initially this is surprising since id has the signature (c -> c) instead of the necessary a -> m b! However, when c is not an atomic type, but rather of the form m d for some (maybe atomic) type d, then we actually have the signature m d -> m d, and if we bind type a to m d and type b to d, we obtain id with actual type signatuare a -> m b, and it can indeed be used as the second argument of (>>=), and everything actually makes sense.

                                                            \n

                                                            Now style is important and so we can do an eta reduction on this, to get a point-free implementation by simply binding the second argument of >>=:

                                                            \n
                                                               join = (>>= id)\n
                                                            \n

                                                            This is all fine and well for the type number, and it does work, but it's also important to understand how it works, so let's see it in a simple example, using the Maybe monad. So let's start by refreshing the implementation of the monad instance:

                                                            \n
                                                            instance Monad Maybe where\n\n   (>>=) :: Maybe a -> (a -> Maybe b) -> Maybe b\n   (>>=) Nothing _ = Nothing\n   (>>=) (Just x) f = f x\n\n   return :: a -> Maybe a\n   return = Just\n
                                                            \n

                                                            So let's now go through the successive bindings when performing (>>=id):

                                                            \n
                                                               Just x = Just (Just 2) => x = Just 2\n   Just x >>= id = id x = x\n   x = Just 2\n
                                                            \n

                                                            This example is pretty much verbatim the same thing for the Either monad and many other monads that follow a similar principle, so let's look at a bit more of a complex example. Let's look at the List monad:

                                                            \n

                                                            instance Monad List where

                                                            \n
                                                               (>>=) :: [a] -> (a -> [b]) -> [b]\n   (>>=) [] _ = []\n   (>>=) (x:xs) f = f x ++ (xs >>= f)\n\n   return :: a -> [a]\n   return = (:[])\n
                                                            \n

                                                            Following the bindings again we have

                                                            \n
                                                               [[2,3],[4]] = (x:xs) => x = [2,3] ; xs = [[4]]\n   (x:xs) >>= id = (id x) ++ (xs >>= id) = x ++ (xs >>= id)\n   [[4]] = (y:ys) => y = [4] ; ys = []\n   (y:ys) >>= id = y ++ (ys >>= id)\n   ys = [] => (ys >>= id) = []\n   => (y:ys) >>= id  =  [4] ++ [] = [4]\n   => xs >>= id = [4]\n   => (x:xs) >>= id = x ++ [4] = [2,3] ++ [4] = [2,3,4]\n
                                                            \n

                                                            So all of this is to say that join actually does what one expects it to do on a list of lists. It joins them one by one into a single list.

                                                            \n

                                                            The Associativity Law

                                                            \n

                                                            The associativity law of a monad can be quite confusing, after all it takes the form:

                                                            \n
                                                               (m >>= f) >>= g == m >>= ( x -> f x >>= g )\n
                                                            \n

                                                            While not too complicated to understand it is difficult to see how it relates to a usual associativity law, which follows the form a * (b * c) = (a * b) * c. To recover the associativity the usual explanation is that one has to see it in terms of the monadic function composition (>=>) and while this is a valid way of doing so, I like to decompose things in terms of fmap, (>>=) and join.

                                                            \n

                                                            So let's use what we did previously on the associativity law, starting on the left side, and replacing the atomic-looking type m with the dependent type M z:

                                                            \n
                                                               (M z >>= f) >>= g\n   = join (fmap f (M z)) >>= g\n   = join (fmap g $ join ( fmap f (M z)))\n   = join (fmap g $ join ( M (f z) )\n
                                                            \n

                                                            and the right-hand side:

                                                            \n
                                                               M z >>= ( x -> f x >>= g )\n   = M z >>= ( x -> join $ fmap g (f x))\n   = join $ fmap ( x -> join $ fmap g (f x)) (M z)\n   = join $ M ( x -> join $ fmap g (f x)) z\n   = join $ M (join $ fmap g (f z))\n
                                                            \n

                                                            And essentially what it says is that if I have two functions f and g I can either do it in an orderly fashion where I apply them sequentially with join . fmap f followed by join . fmap g, or I can apply them both within the constructor and then join once within the constructor and one outside the constructor, and I should get the same thing. In fact if you replace f and g with id; this is the associativity law for monads as usually presented in a standard category theory textbook such as Mac Lane's Categories for the Working Mathematician (and recovering this was the whole point of this exercise in the first place).

                                                            I have had a project on my To Do list for a while: to make a status display from a Raspberry Pi. My vision was to show the state of various things including some HPR stuff, and I had imagined setting up a Pi with a monitor and controlling it over SSH.

                                                            \n

                                                            I started on the project over the Christmas period 2019. I have a Raspberry Pi 3A+, which is a sort of souped-up Pi Zero, which I bought on a whim and hadn’t found a use for (Yannick reviewed this RPi model in show 2711). I also had an old square Dell monitor from about 15 years ago which still worked (at least to begin with).

                                                            \n

                                                            I had imagined I’d write some software of my own with a web front end which ran various tasks to monitor things.

                                                            \n

                                                            However, in my researches I came across MagicMirror2 which I thought I might be able to use instead of writing my own thing.

                                                            Introduction to GNU Autotools

                                                            \n\n

                                                            Have you ever downloaded the source code for a popular software project that required you to type the almost ritualistic ./configure; make && make install command sequence to build and install it? If so, you’ve used GNU Autotools. If you’ve ever looked into some of the files accompanying such a project, you’ve likely also been terrified at the apparent complexity of such a build system.

                                                            \n\n

                                                            Good news! GNU Autotools is a lot simpler to set up than you think, and it’s GNU Autotools itself that generates those 1,000-line configuration files for you. Yes, you can write 20 or 30 lines of installation code and get the other 4,000 for free.

                                                            \n\n

                                                            Autotools at work

                                                            \n\n

                                                            If you’re a user new to Linux looking for information on how to install applications, you do not have to read this article! You’re welcome to read it if you want to research how software is built, but if you’re just installing a new application, go read my article about installing apps on Linux.

                                                            \n\n

                                                            For developers, Autotools is a quick and easy way to manage and package source code so users can compile and install software. Autotools is also well-supported by major packaging formats, like DEB and RPM, so maintainers of software repositories can easily prepare a project built with Autotools.

                                                            \n\n

                                                            Autotools works in stages:

                                                            \n\n
                                                              \n
                                                            1. First, during the ./configure step, Autotools scans the host system (the computer it’s being run on) to discover the default settings. Default settings include where support libraries are located, and where new software should be placed on the system.
                                                              2. \n
                                                            2. Next, during the make step, Autotools builds the application, usually by converting human-readable source code into machine language.
                                                              3. \n
                                                            3. Finally, during the make install step, Autotools copies the files it built to the appropriate locations (as detected during the configure stage) on your computer.
                                                              4. \n

                                                            This process seems simple, and it is, as long as you use Autotools.

                                                            \n\n

                                                            The Autotools advantage

                                                            \n\n

                                                            GNU Autotools is a big and important piece of software that most of us take for granted. Along with GCC (the GNU Compiler Collection), Autotools is the scaffolding that allows Free Software to be constructed and installed to a running system. If you’re running a POSIX system, it’s not an understatement to say that most of your operating system exists as runnable software on your computer because of these projects.

                                                            \n\n

                                                            In the likely event that your pet project isn’t an operating system, you might assume that Autotools is overkill for your needs. But, despite its reputation, Autotools has lots of little features that may benefit you, even if your project is a relatively simple application or series of scripts.

                                                            \n\n

                                                            Portability

                                                            \n\n

                                                            First of all, Autotools comes with portability in mind. While it can’t make your project work across all POSIX platforms (that’s up to you, as the coder), Autotools can ensure that the files you’ve marked for installation get installed to the most sensible locations on a known platform. And because of Autotools, it’s trivial for a power user to customize and override any non-optimal value, according to their own system.

                                                            \n\n

                                                            With Autotools, all you need to know is what files need to be installed to what general location. It takes care of everything else. No more custom install scripts that break on any untested OS.

                                                            \n\n

                                                            Packaging

                                                            \n\n

                                                            Autotools is also well-supported. Hand a project with Autotools over to a distro packager, whether they’re packaging an RPM, DEB, TGZ, or anything else, and their job is simple. Packaging tools know Autotools, so there’s likely to be no patching, hacking, or adjustments necessary. In many cases, incorporating an Autotools project into a pipeline can even be automated.

                                                            \n\n

                                                            How to use Autotools

                                                            \n\n

                                                            To use Autotools, you must first have Autotools installed. Your distribution may provide one package meant to help developers build projects, or it may provide separate packages for each component, so you may have to do some research on your platform to discover what packages you need to install.

                                                            \n\n

                                                            The primary components of Autotools are:

                                                            \n\n
                                                              \n
                                                            • automake
                                                              • \n
                                                            • autoconf
                                                              • \n
                                                            • make
                                                              • \n
                                                            \n\n

                                                            While you likely need to install the compiler (GCC, for instance) required by your project, Autotools works just fine with scripts or binary assets that don’t need to be compiled. In fact, Autotools can be useful for such projects because it provides a make uninstall script for easy removal.

                                                            \n\n

                                                            Once you have all of the components installed, it’s time to look at the structure of your project’s files.

                                                            \n\n

                                                            Autotools project structure

                                                            \n\n

                                                            GNU Autotools has very specific expectations, and most of them are probably familiar if you download and build source code often. First, the source code itself is expected to be in a subdirectory called src.

                                                            \n\n

                                                            Your project doesn’t have to follow all of these expectations, but if you put files in non-standard locations (from the perspective of Autotools), then you’ll have to make adjustments for that in your Makefile later.

                                                            \n\n

                                                            Additionally, these files are required:

                                                            \n\n

                                                            You don’t have to actively use the files, and they can be symlinks to a monolithic document (like README.md) that encompasses all of that information, but they must be present.

                                                            \n\n

                                                            Autotools configuration

                                                            \n\n

                                                            Create a file called configure.ac at your project’s root directory. This file is used by autoconf to create the configure shell script that users run before building. The file must contain, at the very least, the AC_INIT and AC_OUTPUT M4 macros. You don’t need to know anything about the M4 language to use these macros; they’re already written for you, and all of the ones relevant to Autotools are defined in the documentation.

                                                            \n\n

                                                            Open the file in your favorite text editor. The AC_INIT macro may consist of the package name, version, an email address for bug reports, the project URL, and optionally the name of the source TAR file.

                                                            \n\n

                                                            The AC_OUTPUT macro is much simpler and accepts no arguments.

                                                            \n\n
                                                            AC_INIT([penguin], [2019.3.6], [seth@example.com])
                                                            \nAC_OUTPUT
                                                            \n\n

                                                            If you were to run autoconf at this point, a configure script would be generated from your configure.ac file, and it would run successfully. That’s all it would do, though, because all you have done so far is define your project’s metadata and called for a configuration script to be created.

                                                            \n\n

                                                            The next macros you must invoke in your configure.ac file are functions to create a Makefile. A Makefile tells the make command what to do (usually, how to compile and link a program).

                                                            \n\n

                                                            The macros to create a Makefile are AM_INIT_AUTOMAKE, which accepts no arguments, and AC_CONFIG_FILES, which accepts the name you want to call your output file.

                                                            \n\n

                                                            Finally, you must add a macro to account for the compiler your project needs. The macro you use obviously depends on your project. If your project is written in C++, the appropriate macro is AC_PROG_CXX, while a project written in C requires AC_PROG_CC, and so on, as detailed in the Building Programs and Libraries section in the Autoconf documentation.

                                                            \n\n

                                                            For example, I might add the following for my C++ program:

                                                            \n\n
                                                            AC_INIT([penguin], [2019.3.6], [seth@example.com])
                                                            \nAC_OUTPUT
                                                            \nAM_INIT_AUTOMAKE
                                                            \nAC_CONFIG_FILES([Makefile])
                                                            \nAC_PROG_CXX
                                                            \n\n

                                                            Save the file. It’s time to move on to the Makefile.

                                                            \n\n

                                                            Autotools Makefile generation

                                                            \n\n

                                                            Makefiles aren’t difficult to write manually, but Autotools can write one for you, and the one it generates will use the configuration options detected during the ./configure step, and it will contain far more options than you would think to include or want to write yourself. However, Autotools can’t detect everything your project requires to build, so you have to add some details in the file Makefile.am, which in turn is used by automake when constructing a Makefile.

                                                            \n\n

                                                            Makefile.am uses the same syntax as a Makefile, so if you’ve ever written a Makefile from scratch, then this process will be familiar and simple. Often, a Makefile.am file needs only a few variable definitions to indicate what files are to be built, and where they are to be installed.

                                                            \n\n

                                                            Variables ending in _PROGRAMS identify code that is to be built (this is usually considered the primary target; it’s the main reason the Makefile exists). Automake recognizes other primaries, like _SCRIPTS, _DATA, _LIBRARIES, and other common parts that make up a software project.

                                                            \n\n

                                                            If your application is literally compiled during the build process, then you identify it as a binary program with the bin_PROGRAMS variable, and then reference any part of the source code required to build it (these parts may be one or more files to be compiled and linked together) using the program name as the variable prefix:

                                                            \n\n
                                                            bin_PROGRAMS = penguin
                                                            \npenguin_SOURCES = penguin.cpp
                                                            \n\n

                                                            The target of bin_PROGRAMS is installed into the bindir, which is user-configurable during compilation.

                                                            \n\n

                                                            If your application isn’t actually compiled, then your project doesn’t need a bin_PROGRAMS variable at all. For instance, if your project is a script written in Bash, Perl, or a similar interpreted language, then define a _SCRIPTS variable instead:

                                                            \n\n
                                                            bin_SCRIPTS = bin/penguin
                                                            \n\n

                                                            Automake expects sources to be located in a directory called src, so if your project uses an alternative directory structure for its layout, you must tell Automake to accept code from outside sources:

                                                            \n\n
                                                            AUTOMAKE_OPTIONS = foreign subdir-objects
                                                            \n\n

                                                            Finally, you can create any custom Makefile rules in Makefile.am and they’ll be copied verbatim into the generated Makefile. For instance, if you know that a temporary value needs to be replaced in your source code before the installation proceeds, you could make a custom rule for that process:

                                                            \n\n
                                                            all-am: penguin
                                                            \n        touch bin/penguin.sh
                                                            \n        
                                                            \npenguin: bin/penguin.sh
                                                            \n        @sed \"s|__datadir__|@datadir@|\" $< >bin/$@
                                                            \n\n

                                                            A particularly useful trick is to extend the existing clean target, at least during development. The make clean command generally removes all generated build files with the exception of the Automake infrastructure. It’s designed this way because most users rarely want make clean to obliterate the files that make it easy to build their code.

                                                            \n\n

                                                            However, during development, you might want a method to reliably return your project to a state relatively unaffected by Autotools. In that case, you may want to add this:

                                                            \n\n
                                                            clean-local:
                                                            \n        @rm config.status configure config.log
                                                            \n        @rm Makefile 
                                                            \n        @rm -r autom4te.cache/
                                                            \n        @rm aclocal.m4 
                                                            \n        @rm compile install-sh missing Makefile.in
                                                            \n\n

                                                            There’s a lot of flexibility here, and if you’re not already familiar with Makefiles, it can be difficult to know what your Makefile.am needs. The barest necessity is a primary target, whether that’s a binary program or a script, and an indication of where the source code is located (whether that’s through a _SOURCES variable or by using AUTOMAKE_OPTIONS to tell Automake where to look for source code).

                                                            \n\n

                                                            Once you have those variables and settings defined, you can try generating your build scripts as you see in the next section, and adjust for anything that’s missing.

                                                            \n\n

                                                            Autotools build script generation

                                                            \n\n

                                                            You’ve built the infrastructure, now it’s time to let Autotools do what it does best: automate your project tooling. The way the developer (you) interfaces with Autotools is different from how users building your code do.

                                                            \n\n

                                                            Builders generally use this well-known sequence:

                                                            \n\n
                                                            $ ./configure
                                                            \n$ make
                                                            \n$ sudo make install
                                                            \n\n

                                                            For that incantation to work, though, you as the developer must bootstrap the build infrastructure. First, run autoreconf to generate the configure script that users invoke before running make. Use the –install option to bring in auxiliary files, such as a symlink to depcomp, a script to generate dependencies during the compiling process, and a copy of the compile script, a wrapper for compilers to account for syntax variance, and so on.

                                                            \n\n
                                                            $ autoreconf --install
                                                            \nconfigure.ac:3: installing './compile'
                                                            \nconfigure.ac:2: installing './install-sh'
                                                            \nconfigure.ac:2: installing './missing'
                                                            \n\n

                                                            With this development build environment, you can then create a package for source code distribution:

                                                            \n\n
                                                            $ make dist
                                                            \n\n

                                                            The dist target is a rule you get for \"free\" from Autotools.
                                                            \nIt’s a feature that gets built into the Makefile generated from your humble Makefile.am configuration. This target produces a tar.gz archive containing all of your source code and all of the essential Autotools infrastructure so that people downloading the package can build the project.

                                                            \n\n

                                                            At this point, you should review the contents of the archive carefully to ensure that it contains everything you intend to ship to your users. You should also, of course, try building from it yourself:

                                                            \n\n
                                                            $ tar --extract --file penguin-0.0.1.tar.gz
                                                            \n$ cd penguin-0.0.1
                                                            \n$ ./configure 
                                                            \n$ make 
                                                            \n$ DESTDIR=/tmp/penguin-test-build make install
                                                            \n\n

                                                            If your build is successful, you find a local copy of your compiled application specified by DESTDIR (in the case of this example, /tmp/penguin-test-build).

                                                            \n\n
                                                            $ /tmp/example-test-build/usr/local/bin/example 
                                                            \nhello world from GNU Autotools
                                                            \n\n

                                                            Time to use Autotools

                                                            \n\n

                                                            Autotools is a great collection of scripts for a predictable and automated release process. This toolset may be new to you if you’re used to Python or Bash builders, but it’s likely worth learning for the structure and adaptability it provides to your project.

                                                            \n\n

                                                            And Autotools is not just for code, either. Autotools can be used to build Docbook projects, to keep media organized (I use Autotools for my music releases), documentation projects, and anything else that could benefit from customizable install targets.

                                                            Locating computers on a network

                                                            \n\n

                                                            Sometimes you may wish to locate a device on your network. It might be to find rogue devices, or to locate a new device be that a printer, an Internet of Things light bulb, or whatever. In my case I was trying to track down a RaspberryPi. Raspbian now lists the IP Addresses assigned to it when it first starts, but that requires a monitor to be connected.

                                                            \n\n

                                                            Locating using your router.

                                                            \n\n

                                                            This is by far the easiest way to find a new device but it is also the most manual. If you have access to the (WiFi) Router/DHCP server on your network then this should be a matter of logging in and getting the address from the menu area probably called Network or LAN or something like that. So first list all the computers that are on the network. Then turn on your pi, and see if a new one has joined. If you're lucky it may even be labeled Raspberry Pi Foundation.

                                                            \n\n

                                                            In my case I want to locate these devices automatically using a script. So below we will explore some ways that you can approach the problem of locating devices on your network. All of them rely on trying to find the mapping between an Ethernet MAC Address, and a IP Address. It will help to understand a little about how Ethernet works. This is a nice short overview, How does Ethernet work? (animated) by Janos Pasztor

                                                            \n\n

                                                            ARP

                                                            \n\n

                                                            I don't know the network device you will be using so I'd like to share a few ways of doing this using the ARP protocol. This provides a mapping between a device's permanent MAC address and their, often temporarily, assigned IP address.

                                                            \n\n

                                                            When your computer 192.168.1.1 wants to talk to another device it will need to know the Ethernet MAC address of the other device. Let's assume it wants to connect to the local printer 192.168.1.2 that is on the same network, and it knows its IP Address. If your computer has already heard the printer communicate on the network, it will have already added the printer's IP address and MAC Address to its so called ARP table. Over time older entries will be removed from this table either because they are too old, or there were too many entries.

                                                            \n\n

                                                            Linux has a command called arp which will show you a list of the IP addresses mapped to the MAC/HWaddress address.

                                                            \n
                                                            # arp -n\nAddress                  HWtype  HWaddress           Flags Mask            Iface\n192.168.1.254            ether   ff:ee:dd:cc:bb:aa   C                     eno1\n192.168.1.2              ether   00:11:22:33:44:55   C                     eno1\n192.168.1.1              ether   00:aa:bb:cc:dd:ee   C                     eno1\n

                                                            From a Internet Protocol (IP) point of view all your devices in your house are probably in the same Subnet(work). But what if you need to communicate outside your network? For example to ping a well known server 8.8.8.8 to check if you have an Internet Connection. The IP settings also include a Default gateway to send all traffic not intended for the local network.

                                                            Your computer will have many IP Addresses configured but it's a good bet that the network you and your new pi are on is the same one as the default gateway is on. You can find the default gateway using the following command:

                                                            \n
                                                            $ route -n | grep -E 'Destination|^0.0.0.0'\nDestination     Gateway         Genmask         Flags Metric Ref    Use Iface\n0.0.0.0         192.168.1.254   0.0.0.0         UG    100    0        0 eno1\n
                                                            \n\n

                                                            It uses route to show the route table showing IP Addresses and not network names. The first column is Destination and so a 0.0.0.0 there means route everything else to and the to we get from the second column Gateway, which is our gateway.

                                                            \n\n

                                                            You can also get the same information using the following command:

                                                            \n
                                                            $ ip route show | grep default\ndefault via 192.168.1.254 dev eno1 proto dhcp metric 100\n
                                                            \n\n

                                                            And now to just show the IP Address.

                                                            \n\n
                                                            $ route -n | awk '/^0.0.0.0/ {print $2}'\n192.168.1.254\n
                                                            \n\n\n

                                                            From an Ethernet point of view it needs to find the MAC address associated with your router/default gateway's IP address 192.168.1.254, so that it can send Ethernet Frames to it. In our case the address is in the ARP table, but if it wasn't then your computer would broadcast to everyone on the network using a special address ff:ff:ff:ff:ff:ff. When the router/default gateway replies that entry will be added to the ARP table.

                                                            \n\n

                                                            Have a play with WireShark to see what is actually going on on your network. There is a good step by step walk through on Wireshark/Arp on wikiversity.

                                                            \n\n

                                                            All RaspberryPi computers have an Ethernet MAC address starting with b8:27:eb or dc:a6:32. So if your computer and the new pi are on the same network you can look for new MAC addresses starting with b8:27:eb or dc:a6:32.

                                                            \n\n

                                                            Foiled by the Switch

                                                            All is not plain sailing as most modern LAN's use switches to split up the broadcast domain.

                                                            \n\n
                                                            \nSwitches act as buffers, receiving and analyzing the frames from each connected network segment. Frames destined for nodes connected to the originating segment are not forwarded by the switch. Frames destined for a specific node on a different segment are sent only to that segment. Only broadcast frames are forwarded to all other segments. This reduces unnecessary traffic and collisions.\n
                                                            \n\n

                                                            What this means is that although all your computers may be on one big IP network, the devices may be connected to different switches. For example a WiFi Router downstairs, a Cabled Switch in the back room, and a network extender in the attic. All are filtering out unnecessary traffic. While that is a good thing, it does mean that it may not ever see the traffic from the new Pi.

                                                            \n\n

                                                            If we try and contact each and every IP Address on the network, that forces ARP \"Who has?\" traffic, and the answers that come back will be added to the arp table. There are a few ways to force this discovery.

                                                            \n\n

                                                            Discovery by ping

                                                            \n\n

                                                            One way to generate ARP traffic is to use the ping utility.

                                                            \n\n
                                                            \nPing measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water.\n
                                                            \n\n

                                                            To ping an IP Address, just type ping 192.168.1.1. That will send out a continuous ping which you can stop by pressing and holding the ctrl key and then pressing the letter c.

                                                            \n\n
                                                            $ ping 192.168.1.1\nPING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.\n64 bytes from 192.168.1.1: icmp_seq=1 ttl=63 time=0.547 ms\n64 bytes from 192.168.1.1: icmp_seq=2 ttl=63 time=0.493 ms\n64 bytes from 192.168.1.1: icmp_seq=3 ttl=63 time=0.422 ms\n64 bytes from 192.168.1.1: icmp_seq=4 ttl=63 time=0.466 ms\n^C\n--- 192.168.1.1 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3105ms\nrtt min/avg/max/mdev = 0.422/0.482/0.547/0.045 m\n

                                                            We don't actually care about the output, as the point here is to generate some traffic to see who is awake. So we can redirect output and errors to /dev/null. So a good command to do this would be:

                                                            \n\n
                                                            ping -n -c 1 -W 1 192.168.1.1 >/dev/null 2>&1 &
                                                            \n\n

                                                            The options used are to limit the traffic and wait time as much as possible:

                                                            \n\n
                                                            -n Numeric output only.  No attempt will be made to lookup symbolic names for host addresses.\n-c count. Stop after sending count ECHO_REQUEST packets. With deadline option, ping waits for count ECHO_REPLY packets, until the timeout expires.\n-W timeout. Time to wait for a response, in seconds. The option affects only timeout in absence of any responses, otherwise ping waits for two RTTs.\n
                                                            \n\n

                                                            In this solution we will try and ping every host on the network. It would be a bit tedious to do each one by one, so we will make a script to do this for us. It's a very safe bet that your home network will have a private IP range of 192.168.???.0 to 192.168.???.255. This is not a safe assumption in an Office Environment but we can deal with that later.

                                                            \n\n

                                                            So we will try and find the base part of the subnet 192.168.1.1 which will be 192.168.1 and then we will ping each address in turn.

                                                            \n\n
                                                            base=$( ip route show | awk -F '\\\\.|/| ' '/default/ {print $3"."$4"."$5}' )\nfor node in {1..254}\ndo\n( ping -n -c 1 -W 1 ${base}.${node} & )\ndone\n
                                                            \n\n

                                                            I'm assigning the base variable the first three parts of the IP Address and then I am cycling through all possible addresses sending out a ping (a sort of hello message) to each. By wrapping the whole thing in () we can fork each to run at the same time.

                                                            \n\n

                                                            This will force some traffic between my computer and every computer on the network, which will fill up the arp table on my pc.

                                                            And now we find all the computers that are on, and responding to pings on the network. We can see that there is one that starts with b8:27:eb|dc:a6:32, and it has an IP Address of 192.168.1.5.

                                                            \n\n

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We’ve been making small adjustments to our audio mix each month in order to get the best possible sound. Its been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it’s not good at making everyone’s voice the same volume. We’re pretty happy with the way this month’s show turned out, so we’d like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it’s default settings to minimize the silence between people speaking. When used with it’s default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                            Threshold: -30db\nNoise Floor: -50db\nRatio: 3:1\nAttack Time: 0.2sec\nDecay Time: 1.0 sec
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file’s metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            \n Well, since I am sitting at home maintaining a “social distance” I thought I would put down some thoughts about this pandemic and how we will be affected. But a disclaimer to be completely clear: I am not a doctor or a research scientist. I am retired, but I was once a college professor teaching \n \n Statistics\n \n and \n \n Research Methods\n \n . I think this helps me in some way to interpret the information I receive, but when I want authoritative information I look to real doctors, the CDC, and qualified researchers. If you want to know more about what I mean by qualified researchers, you might want to check out my series on interpreting studies:\n

                                                            \n\n

                                                            \n And if you prefer audio to reading, you can download the audio versions at Hacker Public Radio:\n

                                                            \n\n

                                                            \n So, with the preliminaries out of the way, what do we know? We know that this is a virus of a type called coronavirus, which makes it part of the family of viruses that include the common cold, SARS, and MERS. What distinguishes this new virus, technically called SARS-CoV2 (though I usually just call it covid-19, like most reports do) is that it is highly infectious and highly virulent. Highly infectious means it is easily passed from one person to another. Highly virulent means that it can cause death easily. It has been compared in this respect to the 1918 Flu pandemic, which we estimate infected 500 million people worldwide (about 1/3 of the population at that time) and killed at least 20 million to 50 million people, and perhaps more. Note that assigning a cause of death is not a precise science, and medical record keeping in many parts of the world was sketchy at best.\n

                                                            \n

                                                            \n What Can Help?\n

                                                            \n

                                                            \n The ultimate answer to this would be a vaccine. Thankfully, the anti-vaxxers have crawled back under whatever rocks they live under for the time being, but a vaccine is not the perfect answer right now. The good news is that coronavirus appears to be one that does not mutate a lot, which means a vaccine is likely to be more effective than the flu vaccine. Influenza virus changes every year and that makes it a bit of guesswork to figure out. \n \n Scientists are working on a vaccine right now in a crash program\n \n , and again there is some good news on that front. First, Chinese scientists were able to DNA sequence the virus pretty quickly. They found that this virus shares 80-90% of its DNA with SARS, which is why it is named SARS-CoV2. Unfortunately, we don’t have a SARS vaccine because that outbreak died off before work was completed, but the work that was done is something we can build on. But in general, most researchers have said that it will take as much as 18 months even with a crash program. \n

                                                            \n

                                                            \n Usually these take much longer. First you do animal studies, both for safety and for efficacy. For example, one of the early candidates for a SARS vaccine was causing harm to the animals who received it, though they think that problem has now been solved. If the animal trials are promising, you can move on to human trials Stage 1 is to test with a small number of healthy volunteers, looking specifically to test safety. You don’t want to administer a vaccine that kill everyone, or even any significant number of people. If the candidate passes that test, Stage 2 is to administer the vaccine to a few hundred people in an area where the disease is rampant. If it looks like it is working, and no safety issues have arisen, a final trial can involve several thousand people. If it passes that, it can be approved for medical use and move into production. And that adds even more delays, since producing vaccine in large quantities takes a long time. According to Ronald Klain, Obama Administration’s Ebola Czar:\n

                                                            \n
                                                            \n

                                                            \n Developing and testing the vaccine — hard as it is — isn’t the hardest part. Manufacturing hundreds of millions of doses — and getting people to take the vaccine — will be harder and take longer.\n

                                                            \n \n \n https://s2.washingtonpost.com/camp-rw/?e=endpbG5pa0B6d2lsbmlrLmNvbQ%3D%3D&s=5e8b05f4fe1ff6038cf6a56a&linknum=0&linktot=79\n \n \n
                                                            \n

                                                            \n Now, this process can be accelerated to some degree, but not by as much as you might think. Doing the research to find a candidate that might work will take time, and there is no short cut. That is why researchers say a crash program might deliver something in 18 months, as opposed to the decade or more many vaccines require. Sometimes when these studies are done, you get quick results that can lead to dropping some steps. For example, if you have a test group and a control group, and the test group recovers quickly while the control group is dying, any ethical researcher will stop the trial and give the remedy to everyone who needs it. But you are dealing with probabilities in this, and most people are not comfortable with that. They want yes or no answers, and sadly life does not give that all the time. If you are responsible for that decision, if anything goes wrong you will get all of the blame. I’m glad I don’t have to make that decision, though also apprehensive that the people who do make that decision may not be sane adults.\n

                                                            \n

                                                            \n OK, if you we wait for the vaccine, what about medicines to cure the infection? Again, there is work being done here. Several different approaches are being studied. One which we know can work is called \n \n Convalescent Plasma\n \n (aka Convalescent Blood). This takes plasma from people who have recovered from the disease, and gives it intravenously to someone seriously ill. It is an old approach, predating vaccines, but it does work. The transfusion of the plasma contains antibodies made by the person who recovered, and those antibodies can help someone with the disease. But the obvious problem is that it does not scale very well when new cases keep increasing. Other approaches are using drugs developed for different illnesses, in the hope that they are sufficiently similar to covid-19 so that the medication would be effective. This is good since those medications have already passed all of the safety tests, but we just don’t know enough right now. Some reports suggest HIV drugs can help, other reports say they don’t. And so this may bear fruit, but it may be a while yet. The medicine promoted by Donald Trump, hydroxychloroquine, has not been found effective in any good research, and should not be counted on as a valid cure.\n

                                                            \n

                                                            \n And that brings us back to the things we know are effective at this point, which is preventing people from passing on the virus by \n \n social distancing\n \n , i.e. quarantine, and massive testing. If people stay home and do not interact with other people, they cannot pass the disease along and the outbreak will eventually die off. This will work if done properly. To see this, I will use an example I pulled from Steve Mirsky of the \n \n Scientific American Podcast\n \n , which requires less than a minute of spreadsheet work. This uses the reproduction factor R0, which is the average number of people who get infected by each person with the virus.\n

                                                            \n

                                                            \n As we can see, with a factor of R0=1.3, which means each person infects on average 1.3 others, after ten rounds of infection it has only spread to 14 other people. But with R0=2.5, which doesn’t seem that much different, ten rounds means 9,536 people have the disease. Now, there are two primary factors affecting R0. One is the inherent infectiousness of the virus, which is high and out of our control. The other factor is how many people each person interacts with, and that is what we are trying to reduce through social distancing.\n

                                                            \n

                                                            \n Testing is still important, even at this stage, because it does several good things. First, it helps with the allocation of resources if we know exactly where the worst spots are. Second, it saves time and equipment in hospitals if we know exactly who is sick. Third, this gets us data we need to plan for future outbreaks. This pandemic is not the last one we will face, and this one won’t be over soon either. We need to know everything we can about how it spreads. And finally, we need a robust testing regime in place before we can “safely” start to resume our lives. \n

As the current protocols start to relax, \n \n a second wave of infections may arise,\n \n  especially if we don’t have a good grasp on where and how many cases we have in the U.S., said Dr. Eli Perencevich, a professor of medicine and epidemiology at the University of Iowa.\n

                                                            \n “We can’t stay in social distancing forever,” Perencevich said. “So we need to ramp up testing quickly.”\n

                                                            Coq is interactive theorem prover, which comes with its own programming language Gallina.

                                                            \n

                                                            If we wanted to write function that calculates resulting blood type based on two gene alleles, we could do it as following.

                                                            \n

                                                            Start by defining types that represents alleles and resulting blood type:

                                                            \n
                                                            Inductive BloodTypeAllele : Type :=\n  | BloodTypeA\n  | BloodTypeB\n  | BloodTypeO.\n\nInductive BloodType : Type :=\n  | TypeA\n  | TypeB\n  | TypeAB\n  | TypeO.
                                                            \n

                                                            Mapping between them is defined as follows:

                                                            \n
                                                            Definition bloodType (a b : BloodTypeAllele) : BloodType :=\n  match a, b with\n  | BloodTypeA, BloodTypeA => TypeA\n  | BloodTypeA, BloodTypeO => TypeA\n  | BloodTypeA, BloodTypeB => TypeAB\n  | BloodTypeB, BloodTypeB => TypeB\n  | BloodTypeB, BloodTypeA => TypeAB\n  | BloodTypeB, BloodTypeO => TypeB\n  | BloodTypeO, BloodTypeA => TypeA\n  | BloodTypeO, BloodTypeB => TypeB\n  | BloodTypeO, BloodTypeO => TypeO\n  end.
                                                            \n

                                                            Notice that the only way of getting TypeO blood is for both alleles to be BloodTypeO.

                                                            \n

                                                            We can state theorems about the code:

                                                            \n
                                                            Theorem double_O_results_O_type :\n  bloodType BloodTypeO BloodTypeO = TypeO.\nProof.\n  reflexivity.\n  Qed.
                                                            \n

                                                            double_O_results_O_type states that bloodType BloodTypeO BloodTypeO will have value of TypeO. There’s also attached proof for this theorem.

                                                            \n

                                                            Second theorem is longer:

                                                            \n
                                                            Theorem not_double_O_does_not_result_O_type :\n  forall (b1 b2 : BloodTypeAllele),\n  b1 <> BloodTypeO \\/ b2 <> BloodTypeO ->\n  bloodType b1 b2 <> TypeO.\nProof.\n  intros.\n  destruct b1.\n  - destruct b2.\n    + discriminate.\n    + discriminate.\n    + discriminate.\n  - destruct b2.\n    + discriminate.\n    + discriminate.\n    + discriminate.\n  - destruct b2.\n    + discriminate.\n    + discriminate.\n    + destruct H.\n      * simpl. contradiction.\n      * simpl. contradiction.\nQed.
                                                            \n

                                                            It states that if bloodType is applied with anything else than two BloodTypeO, the result will not be TypeO. Proof for this is longer. It goes through each and every combination of parameters and proves that the result isn’t TypeO. Mathematician could write this as: ∀ b1 b2, b1 ≠ BloodTypeO ∨ b2 ≠ BloodTypeO → bloodType b1 b2 ≠ TypeO.

                                                            \n

                                                            If code above is in module called Genes, we can add following at the end to instruct compiler to emit Haskell code:

                                                            \n
                                                            Extraction Language Haskell.\nExtraction Genes.
                                                            \n

                                                            Resulting code is as follows:

                                                            \n
                                                            data BloodTypeAllele =\n   BloodTypeA\n | BloodTypeB\n | BloodTypeO\n\ndata BloodType =\n   TypeA\n | TypeB\n | TypeAB\n | TypeO\n\nbloodType :: BloodTypeAllele -> BloodTypeAllele -> BloodType\nbloodType a b =\n  case a of {\n   BloodTypeA -> case b of {\n                  BloodTypeB -> TypeAB;\n                  _ -> TypeA};\n   BloodTypeB -> case b of {\n                  BloodTypeA -> TypeAB;\n                  _ -> TypeB};\n   BloodTypeO ->\n    case b of {\n     BloodTypeA -> TypeA;\n     BloodTypeB -> TypeB;\n     BloodTypeO -> TypeO}}
                                                            \n

                                                            Now we have Haskell code that started in Coq, has two properties formally verified and is ready to be integrated with rest of the system.

                                                            \n

                                                            This is not a mail delivery solution but rather a way to keep a backup of your email using to a MailDir directory that you can access using your email client. As each message is stored in its own file, you can also use normal tools like find|sed|awk|grep to find messages.

                                                            \n

                                                            This setup can be installed locally or remotely on, for example, a raspberry pi. In that case you can enable a portforwarding rule in ~/.ssh/config to include something like LocalForward 127.0.0.1:2143 127.0.0.1:143

                                                            \n

                                                            Install using aptitude install courier-imap courier-authdaemon

                                                            You can check the status using systemctl status courier-imap.service courier-authdaemon.service

                                                            \n

                                                            I thought it might be appropriate to visit the subject once again. I want to tell you about some new pens and pencils I have acquired, some inks I am enjoying and some of the notebooks I have bought.

                                                            Anonymity has an unfortunate consequence of enabling trolls and abuse. But there are cases where it is important for people to communicate anonymously. In this talk some ideas are presented on how to enable a measure of anonymity without having all of the problems. https://www.zwilnik.com/?page_id=1103

                                                            I have a raspberry Pi model B with the original Pifacecad add on board

                                                            \n

                                                            I recently upgraded the operating system on my raspberry pi from Wheezy (Debian 7) to Jessie (Debian 8), all seemed fine till I tried to run my Python3 project. It reported that the pifacecad module wasn’t present. I tried to install the module using the standard apt-get command given in the Pifacecad documentation. It installed OK for python 2 but It would not install for python 3 as there was a dependency issue with the python-lirc library. I’m guessing the upgrade broke something.

                                                            \n

                                                            I installed a fresh minimal installation of raspbian Stretch (Debian 9) onto a new SD card and ran the standard installation command in the Pifacecad documentation. It all installed but there was a warning about Spi which I had forgotten to enable. I enabled this using the raspi-config util and rebooted the pi.

                                                            \n

                                                            I then tested the installation by running the sys-info.py example that is mentioned in the installation documentation that comes with the pifacecad board.

                                                            \n

                                                            Running this example gave a warning saying that the pifacecad hardware could not be found at this point I gave up and decided instead to run my project in python 2.

                                                            \n

                                                            Of course at first the code wouldn’t run using python 2 and I had to do a bit of digging around to find out what was going wrong.

                                                            \n

                                                            You may find this useful in the unlikely event that you have a project written in python 3 that you want to run in python 2, it might also be useful if you’re going in the other direction.

                                                            One other thing that I briefly stumbled upon was that I believe there is a tool available that attempts to convert python 2 code to python 3 I don’t know anything about it and didn’t bother looking to see if there is a tool to go in the opposite direction which is what I needed. I’ve included a link to the tool below https://docs.python.org/2/library/2to3.html

                                                            We can model state with algebraic datatypes and we don’t even have to write it by ourselves as there’s RemoteData library.

                                                            \n

                                                            Now we can change our model to following:

                                                            \n
                                                            import RemoteData exposing (RemoteData(..), WebData)\n\ntype alias Model =\n    { availableChassis : WebData (List Chassis)\n    }
                                                            \n
                                                              \n
                                                            • availableChassis has four states it can be in:\n
                                                                \n
                                                              • NotAsked, data isn’t available and it hasn’t been requested from server
                                                                • \n
                                                              • Loading, data isn’t available, but it has been requested from server
                                                                • \n
                                                              • Success (List Chassis), data has been loaded from server
                                                                • \n
                                                              • Failure Http.Error, there was error while loading data
                                                                • \n
                                                              • \n
                                                            \n

                                                            For example, while rendering the view, you could do

                                                            \n
                                                                case model.availableChassis of\n        NotAsked ->\n            renderEmptyTable\n\n        Loading ->\n            renderLoadingTable\n\n        Success chassis ->\n            renderChassisList chassis\n\n        Failure error ->\n            renderErrorMessage error

                                                            An issue I just hit in Bash was that I had a quoted string, and I wanted to enclose it in quotes. How to do this?

                                                            \n

                                                            This is the umpteenth time I have stumbled over this issue, and I realised I had found out how to solve it a while back but the information hadn’t rooted itself into my mind!

                                                            \n

                                                            I have always been less clear in my mind about quoted strings in Bash than I should be, so, assuming others might have similar confusion I thought I’d try and clarify things in the form of an HPR show.

                                                            \n

                                                            The problem

                                                            \n

                                                            The thing I was having difficulties with was an alias definition of a useful pipeline:

                                                            \n
                                                            nmap -sn 192.168.0.0/24 | awk '/^Nmap scan report/{print ""; print; next}{print}'
                                                            \n

                                                            This uses nmap (see Ken’s show 3052 for a discussion of its use) piped into an awk one-liner that formats the information returned by nmap.

                                                            \n

                                                            The alias command can be used to store such a command or command sequence as a single simple command. It’s usually added to the ~/.bashrc file so it gets added to every Bash shell you start up (note Bash Tips #22, currently being written, will cover these startup files).

                                                            \n

                                                            An alias definition looks something like this:

                                                            \n
                                                            alias la='ls -Al'
                                                            \n

                                                            The alias itself 'la' is defined as the command ls -Al.

                                                            \n

                                                            So how to make my nmap sequence into an alias given that the commands contain both single and double quotes?

                                                            \n

                                                            Quoted strings in Bash

                                                            \n

                                                            Bash is (to my mind) a bit weird with quoted strings.

                                                            \n

                                                            There are two sorts of quotes in Bash (leaving aside the backquote or backtick – `):

                                                            \n
                                                              \n

                                                            • Single quotes, also called hard quotes ('). The literal value of characters between the quotes is preserved. Single quotes are not allowed, even if preceded by backslash escape characters.

                                                              • \n

                                                            • Double quotes, also called soft quotes (\"). Certain characters within the quotes have special meanings, such as '$' and '\'. Double quotes are allowed in the string when preceded by a backslash.

                                                              • \n
                                                            \n

                                                            There’s a more comprehensive treatment of these quoting types (and others) in the Bash Reference Manual.

                                                            \n

                                                            \n

                                                            To make a variable containing a string with embedded quotes you can do this:

                                                            \n
                                                            $ x='string1'"'"'string2'\n$ echo $x\nstring1'string2
                                                            \n

                                                            What we did here was close 'string1', start a new string enclosed in double quotes \"'\", then append a second string 'string2'. Bash treats the three strings as one, but they have to be contiguous. There must be no intervening spaces1.

                                                            \n

                                                            This solution is rather ugly. You could also use Bash string concatenation to do this, though it’s more long-winded:

                                                            \n
                                                            $ x='string1'\n$ x+="'"\n$ x+='string2'\n$ echo $x\nstring1'string2
                                                            \n

                                                            The same principles hold for double quotes of course:

                                                            \n
                                                            $ x="string1"'"'"string2"\n$ echo $x\nstring1"string2
                                                            \n

                                                            You’d probably not want to do this though.

                                                            \n

                                                            Using backslashes

                                                            \n

                                                            You can use backslashes to escape double quotes inside a double quoted string in Bash as we have seen.

                                                            \n
                                                            $ x="string1\"string2"\n$ echo $x\nstring1"string2
                                                            \n

                                                            However, as discussed earlier, it’s not possible to use backslashes to escape single quotes inside a single quoted string in Bash. However, outside a string a backslashed character is escaped. For example, if you have files which have spaces in their names, you can quote the name or use the backslash escape to protect the spaces2:

                                                            \n
                                                            $ ls -l a\ file\ with\ spaces.awk\n-rw-r--r-- 1 hprdemo hprdemo 0 Apr 22 22:25 'a file with spaces.awk'
                                                            \n

                                                            So, knowing this, you can exit a string, concatenate with a backslashed quote then restart a string like this:

                                                            \n
                                                            $ x='string1'\''string2'\n$ echo $x\nstring1'string2
                                                            \n

                                                            Solution

                                                            \n

                                                            So now we can see how to achieve the alias definition I wanted earlier:

                                                            \n
                                                            alias show_network='nmap -sn 192.168.0.0/24 | awk '\''/^Nmap scan report/{print ""; print; next}{print}'\'''\n\n
                                                            \n

                                                            Epilogue

                                                            \n

                                                            There’s more to be said about this subject, but too much of this stuff is not healthy.

                                                            1. This is quite an artificial example to make a point. You wouldn’t do things this way in reality. Using x='string1'\"'string2\" would also work ('string1' in single quotes, and \"'string2'\" in double quotes). Also, you could just write x=\"string1'string2\" and stop all the messing about, but that would not be much of an example!↩

                                                              2. \n

                                                            2. The backslash is making the space a literal space, otherwise Bash would see it as an argument delimiter, and would look for the files 'a', 'file', 'with' and 'spaces.awk' to list details about!↩

                                                            Install pyenv and pyenv-virtualenv

                                                            \n\n

                                                            Add to ~/.bash_profile:

                                                            \n\n
                                                            export PYENV_ROOT=$HOME/.pyenv\nexport PATH=$PYENV_ROOT/bin:$PATH\n

                                                            Add to ~/.bash_profile (optional):

                                                            The optional bits provide you with the pyenv shell functionality for setting a session-specific Python version, and automatic activation of the virtualenv. Most of the time you don’t need activation, scripts and commands run just fine via the shims, but some tooling around Python may sometimes need to know which virtualenv you’re in.

                                                            \n\n

                                                            Run the export and eval lines in your shell to have the configuration work immediately. Alternatively, do su - yourusername to login to a new session that runs the profile. The - is important.

                                                            \n\n

                                                            You might be able to get away with just opening a new tab or window in your terminal. Whether that runs the profile depends on your settings.

                                                            \n\n

                                                            Set up your pyenv virtualenv for your project

                                                            \n\n
                                                            # Creates the virtualenv named my-project-env using \n# the python named system (your system default python)\npyenv virtualenv system my-project-env  \ncd /path/to/my-project\npyenv local my-project-env\n

                                                            Your system Python may or may not work for this. You might have to install pip and virtualenv. It might still break with some message about ensurepip failing (currently both Nix (20.09pre) python and Ubuntu (18.04) python are failing for me, and older Anaconda pythons also had a broken venv). In that case, use pyenv to install a Python that works, and use that instead of the system python:

                                                            \n\n
                                                            pyenv install miniconda3-latest\npyenv virtualenv miniconda3-latest my-project-env\ncd /path/to/my-project\npyenv local my-project-env\n
                                                            \n\n

                                                            Install pip-tools

                                                            \n\n

                                                            You’ll want to do this inside the virtual environment that you want to manage. Don’t install pip-tools globally.

                                                            \n\n
                                                            cd /path/to/my/project\n# And, assuming you have the shims on your $PATH\n# and you set the pyenv local as shown previously\npython -m pip install pip-tools\n
                                                            \n\n

                                                            Now put your requirements in requirements.in, one on each line, in the form you would give them to pip on the command line:

                                                            \n\n
                                                            somepackage >=3, <4\notherpackage <7\n
                                                            \n\n

                                                            Compile requirements.in to a requirements.txt:

                                                            \n\n
                                                            python -m piptools compile\n
                                                            \n\n

                                                            You could run the shorter command pip-compile for convenience, but using the long form with -m looks it up through your configured Python, and makes it less likely for you to surprise yourself and run a tool in a different virtualenv than you expected. Same with python -m pip above.

                                                            \n\n

                                                            Your requirements.txt will look something like this:

This talk presents an alternative view which is called “minimally social” which only puts in the features needed by the user. In this case, the main focus is on a simple blogging app. There is also a brief mention of a very technical talk about coding. https://www.zwilnik.com/?page_id=1103

                                                            The coronavirus pandemic is continuing throughout most of the world, and I wanted to put down some observations on where we stand today. First, note that I put the date in the title. This is because the situation in some ways changes day-by-day, even though there are continuities. That makes it a dangerous place to be because it is human nature to look for the latest news and jump on it if it looks good. And that is a prime mistake because we do not in fact know enough at this point to be confident in these news reports. I would refer you to my earlier essay, Scientific and Medical Reports, which is highly relevant right now. While I could not have predicted this pandemic when I wrote it, it contains basic principles that are always relevant.

                                                            \n\n\n\n

                                                            The nature of the press is that it is like the carnivorous plant in the movie Little Shop of Horrors, always crying \"Feed Me!\" And of course we are all interested if not to say anxious for any news on the course of this disease and where it is taking us. What this means is that you will see a unstoppable stream of news stories touting the latest study on one or another aspect of this. Add in the desire of politicians to spin things to their advantage, and you have a recipe for disaster. To keep sane, remember a few basic principles:

                                                            \n\n\n\n
                                                            • One study proves nothing. There are lots of studies, and many of them are one-and-done without having any effect on medical practice. If there is an interesting result, it merely indicates an area for further study.
                                                            • Study results are only meaningful when they have withstood peer review and have been replicated by other scientists. This process does produce good results, but only with time. Only in movies do scientists go into the lab and come out 24 hours later with the answer.
                                                            • If you really want to know when all of this will end, there are only two answers. It can end very soon with an accompanying loss of life because the virus is still spreading. This is starting to show up in places that ignore the science. Going outside without a mask and carrying on as usual is not brave, it is stupid.
                                                            • The other answer is that a gradual relaxation of isolation can happen if it guided by sound science. Unfortunately, as just explained, that sound science is still being sought, and will take time.
                                                            • When you see the vast majority of doctors and scientists saying the same thing, that is your best assurance the information is accurate.
                                                            • Right now the number one priority is testing, testing, testing.
                                                            \n\n\n\n

                                                            So, with that background, do we know anything at this point? Yes, we do. But we also have a lot of unanswered questions.

                                                            \n\n\n\n

                                                            Second Wave?

                                                            \n\n\n\n

                                                            The first big question is whether there will be a second wave, and this is something that every qualified epidemiologist I have heard from says is guaranteed. And the reason is that a certain \"fatigue\" sets in with staying in isolation, and at least some people will convince themselves they don’t need to do it. They are wrong, and they will guarantee that second wave. In the 1918 Flu Pandemic, the second wave was far worse than the first wave. And don’t forget there was a third wave in that pandemic until it petered out in 1920. The best thing you can do is keep isolated if at all possible, and follow all of the guidelines:

                                                            \n\n\n\n
                                                            • Wear a mask if you must go out, such as for groceries.
                                                            • Many stores are offering special hours for seniors. If you are one, take advantage.
                                                            • After a shopping trip, wash or disinfect items carefully. Remember that soap is all you need to defeat the virus, but use disinfectant wipes when soap is not practical.
                                                            • After returning, strip and place all of your clothes in the washer. The detergent should kill any virus that is there.
                                                            • Wash your hands with soap frequently.
                                                            • Try not to touch your face.
                                                            • Maintain at least two meters distance from anyone not in your household when you do go out.
                                                            • Try to stay fit. I go for walks in my neighborhood if there aren’t too many others out, and when there is someone else out, I give them a wide separation. I also do gardening in my own yard, and exercise in my home. That won’t prevent you from getting the disease, but it may prevent you from dying of it.
                                                            \n\n\n\n

                                                            Yeah, this is all of the stuff we have been hearing all along. But annoying as it is, it does work if you do it.

                                                            \n\n\n\n

                                                            Is the virus mutating?

                                                            \n\n\n\n

                                                            Yes. In other news, water is wet. Face it, mutation is what organisms do, and that has been true for billions of years. The question you really have is \"Is it getting worse?\" And right now the answer is \"We don’t know.\" Sorry I can’t give you any more determinative answer, but we are only at the \"one study\" phase right now, and we are a ways off from the \"peer-reviewed, replicated consensus\" phase that will resolve this. There are indications that at least this virus does not mutate as much as influenza, but even that may require more study.

                                                            \n\n\n\n

                                                            Am I Immune?

                                                            \n\n\n\n

                                                            We would all love to know if we are immune. This requires two big things to give a good answer. First, does having the disease and then recovering give you immunity? And the sad truth is that we don’t know yet. The common cold is a coronavirus, and you never get immunity. Influenza is a virus, and getting it one year provides no immunity the next. And if getting it once does provide immunity, we still need testing to discover this. The number one priority right now in all locations should be testing, testing, testing. That is the prerequisite for doing any decent epidemiology. There was a report (note: one study) out of South Korea that indicated that some people could get the disease twice, but they re-analyzed the data and decided that it might have been false positives. That is the kind of thing that happens when scientists are trying to do a year’s worth of work in few weeks, which is what they are doing.

                                                            \n\n\n\n

                                                            Is It More Infectious Than We Thought?

                                                            \n\n\n\n

                                                            Again, very unclear. And even less clear is what this implies. An argument is being made that if the rate of infection is higher, given the number of deaths, that would imply it is less lethal. And that is being used to argue in favor of this not being a big deal, so reopen everything. But to put it in perspective, in the 2017-2018 flu season, which was on the high end of deaths, we had 61 thousand deaths in the U.S. Today, in just over 2 months, we have 75 thousand deaths in the US, and that is with all of the extraordinary measures we put in place to keep people safe. To make an argument that Covid-19 is no more dangerous than the flu is to be criminally stupid at best.

                                                            \n\n\n\n

                                                            Didn’t They Predict More Deaths?

                                                            \n\n\n\n

                                                            Why yes, they did. A widely used model in the US is from the Institute for Health Metrics and Evaluation (IHME), at the University of Washington. And they have issued forecasts that ranged from hundreds of thousands of deaths to around 60,000 deaths. Clearly they have no idea what they are doing, right? Not so fast. As the statistician George Box famously said, \"All models are wrong but some are useful\". In this case you have to factor in two things. One is uncertainty, of course. To forecast how many people will die, it helps to know how many people have died, and this has been subject to fierce debate.

                                                            \n\n\n\n

                                                            And here it gets difficult, since one argument is over what counts as a Covid-19 death. And since every one of our 50 states has their own health reporting system, there is a wide disparity. One example of this is the idea of \"excess deaths\". If a given area has a pretty regular death rate for a number of years, and suddenly that death rate jumps 500% in the midst of a pandemic, it is reasonable to suspect those \"excess deaths\" are a result of the coronavirus. But if those deaths get counted, others will argue that it is inflating the numbers, and that only a positive coronavirus serum test should count. Since each state does this differently, this leads to the odd result that the disease appears more or less lethal depending on your state of residence. And that means politicians have incentive to get the numbers they want.

                                                            \n\n\n\n

                                                            The other factor complicating things is the phenomenon known as the \"self-preventing\" prophecy. You see, the initial high estimates tended to be \"This is what will happen if you don’t take strong measures\", and of course they were very high. And we know that governments like the UK and the US looked at those predictions, and started to take some stronger measures. So after a little bit, new predictions came out that were lower as a result of those measures. And now we are seeing misguided efforts to get people to go out and resume normal life, and as a result the newest forecasts are going up again. This is a feedback loop, in other words.

                                                            This conversation took almost an hour, so I split it into two shows:

                                                            \n\n

                                                            • Part 1 talks mostly about the RFC itself, what it means and why.

                                                            • Part 2 goes into personal experiences with the RFC and with syndication in general, in particular in the context of web comics. This is part 1.

                                                            The why

                                                            \n\n

                                                            When serving most RSS/Atom feed readers today, you have to choose: Do you make a complete feed with all the things you ever published, or do you make a shorter feed with just the latest entries?

                                                            \n\n

                                                            This is a trade-off with pros and cons, and it seems like a trade-off you have to make, but a solution to let your Atom feed have the cake and eat it too existed already 13 years ago, if only any of our feed readers would adhere to it: RFC 5005, Feed Paging and Archiving

The link relations defined are current, prev-archive and next-archive. The semantics are clearer: prev-archive refers to previously published entries, and because the contents are stable you can stop when you see a URI to a document you already have. Archive documents are marked with the fh:archive element.

Having had recent problems using the Zoom recorder as a microphone, this time the in-built microphone was resorted to, with even worse results it turned out.

                                                            The recording was made in multichannel mode in anticipation of problems. The distorted channel was processed by using the Clip Fix effect in Audacity, which didn’t seem to change much except reduce the sound level. It was also necessary to find and remove sounds produced by the push to talk key presses. Removal meant replacing these sounds by silence so the two channels would not get out of step. After this the two channels were merged together and silences truncated.

                                                            This episode was processed using Audacity. We've been making small adjustments to our audio mix each month in order to get the best possible sound. Its been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                            Threshold: -30db\nNoise Floor: -50db\nRatio: 3:1\nAttack Time: 0.2sec\nDecay Time: 1.0 sec\n
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            \n

                                                            Hello all those in HPR land. This is Tony Hughes coming to you from Blackpool in the UK. I hope you are all keeping well at the current time of restrictions due to the Corona Virus.

                                                            \n

                                                            In this the second of my recordings talking about restoring of Matchbox and other Die-cast models, I am going to talk of the equipment you will find essential, and some other things that while at the start you could live without, as you get into the hobby you may find extremely useful.

                                                            \n

                                                            So the first thing you will need is a drill for drilling the posts out on the model, both to aid in dismantling them and if you plan to reassemble with the aid of small screws, to drill the hole in the post for tapping to accommodating the screws. This can be a hand held wired or cordless drill or if you have a workshop with a drill press, all the better as this can be used in several ways during the reassembly of the models. That is on my wish list as I don’t have one at the moment.

                                                            \n

                                                            Secondly you will need a set of modelling files for removing the burr on axles, to remove these and the plastic wheels of the base of the model to allow for repainting if required.

                                                            \n

                                                            Wire brushes for cleaning the remains of any paint that didn’t get removed by the paint stripper.

                                                            \n

                                                            Hemostat Clamp Tweezers or crocodile clips on a rod, for use to hold the model during spray painting

                                                            \n

                                                            Additionally, although you can start doing restorations without these, the following will become very useful to help save time and achieve better finishes of the completed restoration.

                                                            \n

                                                            Rotary Tool, the most well known is the Dremel but there are many other manufacturers of similar tools at more economic cost. However beware you do get what you pay for and you may find buying the cheapest you can find a false economy. My cheap Lidl rotary tool which I have had for a few years but barely used, failed after 5 months of use a few weeks ago. The chuck ring thread striped and it will no longer hold bits in the chuck. The rotary tool makes the removal of the axles a very quick job, and cleaning paint stripped castings with a wire rotary brush is a breeze.

                                                            \n

                                                            Another thing you may find useful is a small spray booth with an extractor fan and filter for removing over-spray from the area you are painting in if doing this indoors, particularly if your workshop is in the house. Although one YouTube modeller I follow sprays his models on the cooker with the cooker extractor fan on to achieve a similar result when painting indoors.

                                                            \n

                                                            Finally you may wish to put a compressor and spray gun on your wish list if you get hooked as this gives you a far better range of colours you can paint in, as you can mix your own shades. Some in this community are sticklers for trying to get an exact match to the original colour of the model, others like me at the moment are happy to use shop bought spray paint cans.

                                                            \n

                                                            Small table vice for holding the model. A set of helping hands for the same during painting, particularly when painting fine details.

                                                            \n

                                                            So that’s the tools, now the consumables:

                                                            • Gloves – Rubber washing up gloves to protect from some of the chemicals used to strip paint.

                                                            • Paint stripper, I use B&Q’s DIAL own brand paint stripper. I also use caustic soda for the same thing, occasionally one will work when the other failed to remove the paint, it depends on the original paint applied to the model.

                                                            • Cans of spray paint to repaint the model, both primer and the final colour. You may also want a can or two of a clear coat to give that extra protection after painting or giving a gloss finish if the paint was a matt or satin finish.

                                                            • Not essential at the start but I also use a UV resin glue that cures very quickly after exposure to a UV light torch, this can be added and cured in layers if needed and remains flexible so can be useful for repairs on cables as well as my modelling.

                                                            • Finally you need your first model to start work on, these can be found in charity shops, online auction sites or maybe in your loft or garage if you have any of your childhood models kicking around needing to be re-loved.

                                                            She is adept at reading lips and learned to speak despite being deaf.

                                                            still worked, so I wired it to the Pi on the 5v line. It runs at half the

                                                            I have 2 Pi's connected via ethernet. One is on 192.168.2.5 with a gateway of
                                                            192.168.2.6, with the other on 192.168.2.6 with a gateway of 192.168.2.5.
                                                            Essentially just a crossover network. The reason for this is running Kodi on Pi4
                                                            has choppy video, but is better at running video encoding. So I linked it to a
                                                            Pi3 to run Kodi via a samba share from the Pi4.

                                                            Since I sent the show notes, I had problems using the GUI way to set up
                                                            a static IP address on the OSMC section. Here is a more concise way to go about\nit.

                                                            \n

                                                            It seems OSMC uses connman, so in order to create an ethernet static IP:

                                                            \n

                                                              Create a config file with your editor:

                                                              sudo vim /var/lib/connman/osmc.config\n

                                                              Reboot your RPi or restart the connman service:

                                                            \n

                                                            If you opt to restart connman, you’ll loose the connection.

To recap this is the 3rd in a series of shows about my hobby of restoring Matchbox and other Die-cast models. In the first 2 shows I introduced the concept and discussed the tools and other equipment you would need to start this hobby.

                                                            In this episode I have decided to return to where it all started with the Matchbox No28 the Jaguar Mk10. Please refer to the show notes for the pictures of the process as we move along. You can see in the first picture the 4 castings used in this process.

                                                            This is a lovely little casting and is a nice introduction to the techniques used in the process. Also I have several of these that I can strip down to their components and that should give us enough quality parts to reassemble at least one good example, hopefully one or two more.

                                                            The next picture shows you the base of the model and that there is a mushroomed post that needs to be drilled out at the rear of the model, the front of the base is retained by a tab, which once the post is removed and the base released, this can be slid forward to free the tab.

The post is drilled out with a 4mm drill bit, and as you can see in the next picture on this particular casting I was a little over zealous and damaged the base a little, although as it is the base it’s not a major issue.

                                                            I then released the base by prying it off the remainder of the post with a small flat bladed screwdriver to lever it of the body. This now allowed the removal of the inner plastic forming the seating and holding a small plastic suspension piece. In the next picture you can see the casting without any internals but with the plastic window unit still held in place with another shallow mushroom post.

                                                            Being very careful not to be too aggressive drilling this mushroom holding the windscreen unit, it is removed, again with a 4mm drill bit, so that a little pressure from a flat blade slid between the roof and the glassing unit will allow it to pop out without it breaking. It usually takes several attempts of a little drilling, trying with the flat blade, then if not coming free, a little more drilling until it pops off.

You will have to wait for the next instalment to find out what happened next. I’ve got to keep you wanting some more of this rambling tale.

                                                            Whether you are writing a simple darts simulation 8-bit computer game or are traversing the galaxy Elite-style, you might well find yourself tangling with the mathematical concept known as the metric. In this episode I describe the mathematical concept of a metric which I address with the following questions. Brief answers are provided below but the show, I hope, gives more context and colour.

                                                            \n

                                                            What is a metric?

                                                            \n

                                                            A type of ruler that is used in mathematics.

                                                            \n

                                                            Why not just use a ruler?

                                                            \n

                                                            You can if all you want to do is measure distances in real life but if you want to work out distances from coordinates you need a metric.

                                                            \n

                                                            What's the simplest example of a metric?

                                                            \n

                                                            In 1D, distance s equals change in x coordinate.

                                                            \n

                                                            OK, can I have a more interesting example please?

                                                            \n

                                                            On a flat 2D surface, distance squared is the change in x squared plus change in y squared.

                                                            \n

                                                            Isn't that pythagoras?

                                                            \n

                                                            Yes, it is, but using the word distance and two co-ordinates.

                                                            \n

                                                            What other co-ordinates can we use for a flat 2D surface?

                                                            \n

                                                            Those x and y co-ordinates are called Cartesian co-ordinates. Instead we can use polar co-ordinates: radius r, and the angle φ (or phi) measured clockwise from the vertical. These might be more convenient in some cases, say for a dart board computer game, or if you are working with a compass bearing, eg head east for 1 km would become start at the origin (r=0) and move with phi=90° until r=1 km.

                                                            \n

                                                            Does Pythagoras still work in polar coords?

                                                            \n

                                                            Yes and no. No, it is no longer true to say that distance squared equals radius squared plus φ squared, but since the geometry is the same - a flat 2D surface - we can say that a change in distance squared equals the change in radius squared plus radius squared times the change in φ squared.

                                                            \n

                                                            Why do we have to talk about changes in s, r and φ?

                                                            \n

                                                            Because one of our coordinates now appears in the metric. That is, the radius squared multiplies on to the change in φ squared. This means that a change in φ depends on r. In other words, bigger circles have bigger circumferences. Actually, it's more intricate than that, as we must deal with infinitesimals: quantities which are very, very, very small but not zero.

                                                            \n

                                                            Can we use Cartesian or polar co-ordinates on the surface of the Earth?

                                                            \n

                                                            Only over short distances, much smaller than the radius of the Earth which is 6400 km. So up to about 100 km that's fine for many purposes, but not when flying a plane over great distances, say London to Singapore.

                                                            \n

                                                            Why not?

                                                            \n

                                                            The surface of the Earth may look locally flat but of course the Earth has a curved 2D surface. This means that this surface has a non-euclidean geometry, which means that Pythagoras does not hold and we cannot even define Cartesian co-ordinates, let alone use them.

                                                            \n

                                                            I want to know more OR my mind is not fully blown.

Instead I was confronted by a very dry, only slightly hoppy (20 IBU) beer without much flavor but a lasting aftertaste that is slightly sweet. Those Shiner boys aren't messing around, they make beer with cactus. I really did not enjoy the first beer but by the end of the six it is growing on me. Though it would be refreshing on a hot day, I doubt I will be buying it again.

                                                            As always; remember to visit the HPR contribution page HPR could really use your help right now.

                                                            P.S. Some people really like finding mistakes. For their enjoyment, we always include a few.

                                                            Our Audio

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We've been making small adjustments to our audio mix each month in order to get the best possible sound. Its been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                            Threshold: -30db\nNoise Floor: -50db\nRatio: 3:1\nAttack Time: 0.2sec\nDecay Time: 1.0 sec\n
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            \n

                                                            The regularity of switching between left and right hands (intuitively, and almost surely) decreases the entropy of the password, so use markov models to make that happen for the most part but critically NOT enforce it.

                                                            Finally, generating the matrix by hand was a bit of a pain, so I made it a bit easier by making a small procedure with few control knobs (the variables SWITCH_HAND and SWITCH_CHAR which control how likely it is that a character pair will result in a hand switch, or a switch between general characters and digits).

                                                            Good day to all in HPR land, this is Tony Hughes coming to you again from Blackpool in the UK. To recap this is the 4th in a series of shows about my hobby of restoring Matchbox and other Die cast models. In the last show I went through the process of stripping the models down to their component parts. In this episode I will discuss the process I use to remove the paint and prepare the casting for repainting and reassembly.

                                                            \n

                                                            So first off, and I should have said this last episode, a health and safety warning. If there are young people listening to this some of the things talked about on today's show require parental supervision, and are not recommended for young people unless properly supervised. So with that public service announcement out of the way let's get on with the show.

                                                            \n

                                                            So before the base can be put in the paint stripper the wheels and axles need to be removed. As you can see from the picture there are flanges holding on the wheels to the metal axle and one side is only a small flange.

                                                            \n

                                                            This can be removed with a small needle file or a small rotary file attachment for my rotary tool. Once removed the bases can be put in with the rest of the casting for paint removal.

                                                            \n

                                                            \n

                                                            So let's talk about paint removal, obviously the first one you will think of is some kind of chemical paint stripper and I use 2 different methods of this. The first and probably the safest in the first instance is a commercial paint stripper from one of the chain DIY stores here in the UK, B&Q. There is a local store about 10 minutes drive from me so it is convenient during normal shopping times just to pop in and grab a 2.5Ltr container of their own brand DIAL paint stripper that is fantastic for this job and quite economic.

                                                            \n

                                                            The second is a little more aggressive if you need fast results but requires a little more in the way of care when using it as it is very corrosive and can be harmful if the fumes are breathed in, or the product gets onto your skin or in your eyes. This is caustic soda and I buy this through eBay and have it delivered in 1Kg pouches. It needs to be stored in an air tight container in a dry environment to keep it from getting damp as this is a potential fire hazard as if it gets contaminated buy moisture a chemical reaction starts which generates heat. So if you go with the caustic soda method you need to take adequate safety precautions. With the Jaguar I mainly used the caustic soda method to remove the paint but one casting I put in the paint stripper to show that method.

                                                            \n

                                                            With the caustic soda place the castings in a jar with enough room to cover with just boiled water so that it does not overflow when the caustic soda crystals are added slowly, I use a long handle tea spoon and add 2-3 tea spoons of the soda until it has a good fizz. Then leave for about 15 minutes but the longer the better, I sometimes do this and leave over night and this gives a great result. Remember to wear gloves when doing this to prevent getting the caustic on your hands.

                                                            \n

                                                            With the paint stripper I have a plastic click lock box with this in that I immerse the casting into and leave for several hours for best results. This can be reused many times as you can see in this picture keeping it an economic method as most of the stripper is left in the box when you remove the casting. The results for both methods are similar, but I find the caustic although you need to be careful, is the less messy of the two options, and the casting is easier to clean after paint removal.

                                                            \n

                                                            \n

                                                            So after removal of the paint the castings are polished up with either a hand wire brush or a wire brush attachment for the rotary tool. You can see the base before and after and a picture of the polished main casting in the notes.

                                                            Sort by price low to high, and loop through, finding what support there is for TWRP. That will tell you how open the phone is. If the Manufacturer support (the spirit of) unlocking, then remove them from the list.

                                                            After finding a phone that can be unlocked and rooted, then check to see if there is an official version for LineageOS

                                                            \n

                                                            If no phone meets all the requirements then try the next one.

                                                            It's very likely you will not find a phone. You are then faced with the choice of adjusting your parameters, for example picking a more expensive model, but at the end of the day be prepared that you may not find a phone.

                                                            \n

                                                            If you do find a phone, it's very likely that it may be a different version than the one supported. I have had to return several phones that I had unlocked and just hoped that the supplier would take them back and refund me.

                                                            \n

                                                            Even on supported phones, especially newer ones, it's quite often that a major piece of functionality will not work. I have had issues with no GPS on one phone, and bluetooth/wifi not working on another until files were manually edited on each reboot.

                                                            \n

                                                            Do not do this if you want a stress free life, and also if you are not willing to accept the waste of all the money, and time involved.

                                                            Most of the shows we process require us to make some level of modifications to get them posted. This ranges from fixing tags to a complete rewrite of the shownotes, or verifying whether intros were actually added or not.

                                                            \n

                                                            Each modification that we make means that it requires more human intervention and prevents us from being able to completely automate the upload process. In addition there is a non trivial amount of time needed to \"fix\" these issues. This can range from a few minutes to an hour or more per show, and with 260 shows a year this mounts up.

                                                            \n

                                                            We normally don't contact hosts about these issues as it is usually quicker to fix the issues than composing emails, and waiting for the reply that may never come. For the most part our experience has been that hosts are more than willing to fix these issues if they are aware of them.

                                                            \n

                                                            As part of the ongoing steps toward automation, would hosts be open to the idea of getting a processing report once we have posted the show? This would list all the issues the test tools found and the steps that we needed to take to rectify them.

                                                            Sometimes an error or omission in notes for an HPR episode isn't noticed until the show is posted to the site. In recent times a few hosts have sent in their changes by way of comments. This is not ideal:

                                                            Roleplaying games open you up to a seemingly unlimited array of possibilities taking place in many universes. But truly unlimited freedom would literally mean nothing without a context of history, lore and rules for your adventures. Klaatu and mcnalu talk through what open and free mean in roleplaying games with a particular focus on Dungeons & Dragons which Klaatu has been been running for the HPR community in recent months.

                                                            If you want to play D&D you can go to the website of its publisher Wizards of the Coast and browse for the player and other manuals. But if you want to play but can't or won't pay then you can use the System Reference Document (SRD) which is published under the Open Game License (OGL). You can even use that document to create and publish your own adventures.

To do this for D&D you need to publish through the Dungeon Masters' Guild.

                                                            6. Used digital outputs listed in the sketch to power the LED indicators

                                                            7. Used pins 10 to 12 as AnalogWrite pin to provide the power to the solid state relays.

                                                              8. \n

                                                            8. Used a dremel to separate the power to the hot side of the two power outlets

                                                            Good day to all in HPR land, this is Tony Hughes coming to you again from Blackpool in the UK. To recap this is the 5th in a series of shows about my hobby of restoring Matchbox and other Die cast models. In the last show I went through the process I use to remove the paint and prepare the casting for repainting and reassembly. In this episode we will look at the painting of the castings and 'Spoiler' what to do if things go wrong.

                                                            \n

                                                            After polishing and before painting I degrease the casting in some alcohol. I use a cheap own brand nail polish remover from the Co-Op but there are many ways of doing this and as many products on the market, so use what you have to hand. Even a good clean in hot soapy water, dry with a lint free cloth and then a wipe over with alcohol wipes works well. Remember to wear gloves when handling the casting after this process as the grease from your hands can undo all your hard work.

                                                            \n

                                                            So the first thing to say is that I am still in the early stages of learning this hobby and use what are referred to as 'Rattle' cans in this community, it just means spray can painting rather than the use of an Air Brush, which I will be moving onto at some point so I can mix my own paint colours and not just those available in a spray can.

                                                            \n

                                                            So far I have been painting the casting outside during a warm dry day with little or no wind, or in a sheltered spot behind the garage if the wind is a little strong. I have now set up a small portable spray booth in the garage for this so will be able to paint in all conditions weather wise, which will make life easier.

                                                            \n

                                                            \n

                                                            So back to the casting, I use a Hemostat Clamp to hold the casting on this model it is attached to the post that holds the model together as this will not be seen when reassembled, I used a grey primer, spraying light coats all over the model until it is completely covered in the primer. Priming helps smooth out any small imperfections for the final paint coat, and as the casting is over 50 years old, it also lays down a consistent base colour and ensures that the colour coat should be the same all over when final paint is applied. As you can see in the picture it also shows up the casting lines and if desired these can be filed away prior to final painting, as this is a restoration I left this casting as original as possible, and left these in.

                                                            \n

                                                            \n

                                                            After leaving the casting to dry for about an hour I came back with the colour coat, the original model was a metallic brown, but the nearest match I was able to find in the local pound shops is a metallic gold. Not perfect but the final results look good, but a little lighter than the original paint. I applied the paint in smooth fine strokes, getting what is called a tack coat of the paint all over the model casting to start, then applying another coat (the wet coat) all over until there is no sign of the primer and all looks smooth but with no runs in the paint finish. The balance needs to be just right with not too little or too much paint, but with practice you get there in the end. Unforseeably on this occasion there was a reaction with the primer on the rear of the model which caused bubbling of the paint.

                                                            \n

                                                            So after allowing the paint to fully cure I used a little wet and dry fine sanding paper to smooth out this area and gave the casting another coat of paint, and fortunately this time all was well as you can see from the pictures in the show notes.

                                                            \n

                                                            While the casting was fully curing I turned my attention to the screen plastic. I found the best of the ones I had salvaged, from the 4 castings, picture 008 in the notes, and gave it a polish with some auto sol polishing compound using a cotton bud, and it came out quite nice. I then gave it a wash in soapy water to remove the residue of the polishing compound and after drying gave it a dip in some Pledge floor shine, it works great.

                                                            Although the original casting had a black painted base I liked the look of the polished base so decided to leave this as it was, but if painting the base it is the same process as the main casting.

They offer a way to connect any two points with the shortest distance. Lines in 2D or great circles on a sphere are examples of what is called a geodesic. In physics, particles that are not subject to any forces will follow geodesics.

                                                            In Einstein's General Theory of Relativity, the presence of mass or energy will alter the shape of spacetime and that will determine the metric. From the metric you can derive the geodesics and from that you can predict the motion of objects with no forces acting on them. In this way you can do away with the approximation that is Newton's gravitational force and replace it by a description that only involves the curvature of spacetime. I only touch on this in this show but will likely return to it in future shows.

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We've been making small adjustments to our audio mix each month in order to get the best possible sound. Its been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                                Threshold: -30db\n    Noise Floor: -50db\n    Ratio: 3:1\n    Attack Time: 0.2sec\n    Decay Time: 1.0 sec\n
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            This episode covers how I keep track of what I'm listening to

                                                            \n

                                                            I almost never produced this podcast as I discovered part way through that I had covered it in my show \"Describing how I listen to podcasts PART 2\" (HPR 2889). I'm conscious I have a tendency to repeat myself in real life, I think this is because I have such a terrible memory. Despite this I decided to continue with the episode but will go into subject in a bit more detail.

                                                            \n

                                                            These ideas slowly evolved over time and I think some of them may now be redundant. I think I need to do some tidying.

                                                            \n

                                                            As I've previously mention I used cordless headphones to listen to my podcasts and audiobooks. The headphones come with base transmitter which was originally plugged into my old Compaq home server. This server was generally turned on when I came home from work and turned off before going to bed. Each night I had to remember which track I was on and where about in the track. I often forgot and had to try and find the place again. This quickly became a tiresome task.

                                                            \n

                                                            My first solution was to use some bash Kung Fu jiggery pokery to create list of files which I placed in each podcast folder. In the process I learned a bit about using bash commands.

                                                            \n

                                                            Command used to create index

                                                            \n
                                                            id3v2 -l *.mp3 | grep 'TIT2' | cut -c44- >> readme.txt\nid3v2 -l *.mp3 | grep 'TIT2' | cut -c44- | egrep 'HPR[01][9][7-9]' >> readme.txt\nid3v2 -l *.mp3 | grep 'TIT2' | cut -c44- | egrep 'HPR[1-9]' |less >> readme.txt\n========================================================\n========================================================

                                                            Example output

                                                            \n
                                                            epr0006.mp3 - dosman                            complete\nhpr0010.mp3 - linux boot process, part 1        complete\nhpr0012.mp3 - zen virtulization                 complete\nhpr0018.mp3 - book review                       complete
                                                            \n

                                                            The downside of this was that at the end of each night I had to remember to update my file lists recording what I had listened to and what position I was in within the track. From time to time I had to update this list by appending the latest episodes sitting on my server using the previous id3v2 command.

                                                            \n

                                                            As you can imagine this took up a fair amount of time and became very tiresome, I would sometimes forget to do it this would cause me a headache next time I started listening to my podcasts.

                                                            \n

                                                            My next solution involved creating a bash script that attempted to persuade my music player moc to find the track I was previously listening to.

                                                            \n

                                                            The script sometimes worked but it was a bit flaky and didn't always work.

                                                            \n

                                                            My final solution is in multiple parts

                                                            \n

                                                            The 1st part consists of a bash script and a log file, it's a handy way of checking the last podcast episode and last position, this information is recorded to the log file when the front end of moc is exited by hitting Q. Of course this doesn't work if mocp closes for any other reason ie if I forgot to hit Q or my Pi crashed.

                                                            \n

                                                            First script

                                                            The 2nd script I use runs as a cron job every night at 11.01pm. This script keeps track of all the files copied to the MP3 directory of my raspberry pi, this is where I put my podcasts that I want to listen to. I can then grep the log file to see the latest version of a particular episodes that's been copied to my mp3 directory as from time to time I delete the episodes I've listened to before copying new ones in.

                                                            This added an option to seach for a string in my episodes position logs to easily find out what the last episode I listened to of a particular book or podcast, the output is piped to less as numerous lines can be returned.

This year they digitally did it all, which was engaging and fun. I've never attended, but I loved this year, where I could be a part of the experience.

                                                            Good day to all in HPR land, this is Tony Hughes coming to you again from Blackpool in the UK. To recap this is the 6th in a series of shows about my hobby of restoring Matchbox and other Die cast models. In the last show I went through the process I use to paint and prepare the casting for reassembly. In this episode I will discuss how I put back the wheels onto the base and reassemble the final model, before revealing in the show note pictures how the model came out.

                                                            \n

                                                            So before putting back the plastic wheels onto the axles I polished the axles in my drill bit using a little bit of fine wet and dry emery paper.

                                                            \n

                                                            \n

                                                            After selecting the best 4 of the plastic tyres from the models we originally dismantled I washed these in a little soapy water and after drying they these were fit for putting back on the restored model. The cleaned up axle is assembled on the base with the first tyre in place with the large dome end of the axle sat on a nail punch held in a vice. The second tyre is then placed on the axle and holding this all in place a small hammer is used to peen over the end of the axle by hitting it gently so the end is peened over but the axle does not bend. It is possible to do this stage in a drill press using another nail punch in the drill chuck, but I do not have a drill press at the moment, so have to do this the old school way, with a bit of brute force and ignorance.

                                                            \n

                                                            \n

                                                            So we now have all the parts ready for reassembly. The base has the axles and wheels back on, the screen has been polished and the plastic seating given a clean in soapy water and dried, and the body is repainted and ready to go.

                                                            \n

                                                            So being careful not to damage the paint work the casting is placed with the base side up and the window unit is placed into it.

You have to ensure that the tab with the tow hitch (yes Matchbox put a tow hitch on a posh car) is fully over the retaining post or the base will not seat properly.

                                                            The base is then placed back on the model by sliding it over the tab at the front and clicking it down over the rivet post.

                                                            I then used some '5 second Fix' UV glue to glue around the post to hold it in place. You can also drill out the post with a 1.5mm drill and using an M2 tap then use a small M2 screw to hold the base in place, but in this case I was happy with the glue as it was for display and will not be handled frequently enough to require the more secure retention of a screw. With these small models there is a risk of damaging the post while drilling and tapping them so it is personal preference as to the method used to hold it all together at the end.

These small models are comparatively easy, but some of the larger scale models with many more parts can take many days to restore, and require a lot of patience to do so. But from small beginnings we all start, and maybe in the future I will feel confident enough to tackle something a little more complicated. I have recently done a few models with opening doors which have a retaining spring holding them in place.

At the moment I'm not sure about what, but I will be back, so Ken can rest assured I still owe him a show.

                                                            This show came about because of an email from Dave Morriss on the 4th March 2020

                                                            \n

                                                            The upshot of it was that Dave came into possession of an illuminated lantern that he wanted to use. He had a problem however as the lantern in question was sealed and he didn't know the working voltage of the bulb within. He asked me if there was a way of working it out.

                                                            \n

                                                            Well first of all before I go any further I should probably say I'm not a bulb expert, however I set about doing a little investigating. What I was about to discover is that calculating this is not as straightforward as you might think.

                                                            \n

                                                            One thing you might think to do is to use a meter to measure the resistance of the bulb. Even doing this however is fraught with difficulty because measuring the resistance of a cold bulb not at working temperature will give a misleading answer. This is because the resistance of a standard bulb changes with temperature.

                                                            \n

                                                            I can demonstrate this by measuring the resistance of two light bulbs I have lying around the house.

                                                            \n

                                                            One is a clear traditional Bayonet tungsten filament house bulb rated at 40W. I live in the UK so its operating voltage is 240V I used my trusty Fluke 77 Digital Ohmmeter but any meter capable of measuring resistance will do. This bulb at room temperature measured a resistance of 108 ohms

                                                            \n

                                                            The other bulb was a Halogen E14 screw in bulb rated at 28W and its operating voltage like the previous bulb was 240V. Its measured resistance at room temperature was 144 ohms)

                                                            As per usual I used google and come up with somebody asking the same sort of question at https://www.candlepowerforums.com/vb/showthread.php?64832-How-to-identify-voltage-of-an-unmarked-bulb yes it seems like there a forum for just about anything you can think of.

                                                            \n

                                                            One person on the forum made the point that there really isn't such a thing as a working voltage it just depends on how long you want the bulb to last. For this reason I always turn down the brightness on any car I own that his dimmable dashboard lights changing these bulbs can be a real pain and or can be expensive.

                                                            \n

                                                            Sometimes the stated working voltage for a bulb can be misleading for example a car bulb will often state a working voltage of 12V but is likely to be running at a higher voltage when the engine is running due to the operation of cars alternator.

                                                            \n

                                                            Another person suggested trying to estimate the length of the filament and using this to determine the working voltage.

                                                            \n

                                                            Yet somebody else suggested just using a variable supply and to just slowly increase the voltage until a reasonable amount of light is generated. This might be quite simple if it's a low voltage bulb and you could even use some batteries lying around connecting them in series adding one battery at a time until the required brightness is achieved.

                                                            \n

                                                            It isn't so simple if bulb requires a higher voltage.

                                                            \n

                                                            In the end I just passed this information onto Dave wishing him luck in his path to discovering the optimal working voltage for his lantern.

                                                            Our Audio

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We've been making small adjustments to our audio mix each month in order to get the best possible sound. Its been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extremely effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too aggressively your audio may sound sped up and choppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                                Threshold: -30db\n        Noise Floor: -50db\n        Ratio: 3:1\n        Attack Time: 0.2sec\n        Decay Time: 1.0 sec\n
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on peaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can \"Mix and Render\" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being \"crashy\" but if you remember save after every major transform, you will wonder how it ever got that reputation.

                                                            As a boy I was allowed to have a penknife from about the age of 10. Since then I have tended to carry pocket knives with me on a regular basis.

                                                            \n

                                                            Hello everyone, my name is Cedric and I'm here again with another story on pentesting and security, straight from the trenches.

                                                            \n

                                                            Today I'm going to share a story with you about an assignment we did some time ago for a large entertainment company. Our client, like many entertainment companies, produces a lot of intellectual property. So, one of their biggest concerns is that someone might physically break into their premises and steal some of these designs and products. They had already taken some precautions, like installing intrusion detection alarms and access controls on all doors etc' The access controls they installed even had a dual function and could be used both as an RFID reader and as a fingerprint reader. So, they were already trying their best to secure their on-site intellectual property. And that's also the reason why they hired me and my team: they wanted to check if their investment in security was actually worth its money so far.

                                                            \n

                                                            We proposed a plan to hack them, in any way our devious minds could possibly think of. Everything was on the table: We could try and hack ourselves in. We could social engineer ourselves in, basically by manipulating people and abusing their trust and confidence. We could do all of that, and we would, eventually. But first, the grand opening of this show, would be an attempt to physically break into their premises at night. And yes, that was as much fun as it sounds ;-)

                                                            \n

                                                            Our approach was basically the same as that of a professional burglar: we'd start with a week of preparation and scoping the place.

                                                            \n

                                                            So how do you do this? Well, we knew the address of course so first we checked out the place on Google Maps. And we were pretty lucky: Google had just recently updated their imagery of the area which meant we had recent maps to work with and the entire thing could be viewed in 3D with a fair amount of detail. That's pretty much as perfect as it comes when you're planning to do a major heist on a place in the physical world out there :-) So, we started with scouting the area from behind our laptops. We saw where all the entrances to the building were. We also saw that on the frontside the building just gave access to the street, while on the backside of the premise there was a public park. This looked very promising as a potential entrypoint, so our next step would be to actually physically go there and scout the area.

                                                            \n

                                                            So, first we went there during daylight hours and just took a drive around the block using a rental car. We'd look for entrances to the building, camera's guarding these and the general view of the area, basic things… We didn't spot any cameras on the outside of the building. So we figured it would be pretty safe to take a walk and scout the area by foot. There was foot traffic but not too much, so we wouldn't draw any attention by just casually walking around and having a closer look.

                                                            \n

                                                            The main entrance to the building was in a quiet street which led to a small square where a few kids were playing, and on the other side there was a street with some shops and a few restaurants. The entrance to our clients building had a gate through which we could see a quiet courtyard and the general layout of the building. The first thing that drew our attention was an access control device guarding the entrance, it was a fingerprint reader and it had a brand name Suprema printed on it. Straight across the courtyard we could see the trees of the neighboring park. There was a rooftop terrace on the first floor which gave access to the offices of our client. We also noticed the wall that separated this terrace from the park and it was huge, at least 6 meters.

                                                            \n

                                                            We couldn't hang around for too long of course so we decided to continue our walk to the second entrance we spotted just around the corner. We could recognise its anonymous door next to a restaurant because it was guarded by the same Suprema fingerprint device. The restaurant however seemed quite popular, and it had a terras in front of it with a dozen tables, so that pretty much dismissed this entrance as a possible entry for our heist.

                                                            \n

                                                            Needless to say that while we walked around the block we were also continuously scanning the area for Wifi and bluetooth devices. But nothing interesting had shown up so far. We had spotted our clients network but it was protected. We probably could use this information to set up rogue access-points later during our assignment, but for now this information was of little use to us.

                                                            \n

                                                            We continued our walk and took a left to end up at the park bordering to the other side of our clients building. While the park was empty at that moment, we didn't really feel at ease. On one side the park bordered an apartment building and all of its rear terrasses faced this park. We went to the wall at the far end of the park as casually as possible, and inspected it. It had two large windows, giving the people working in the offices on the inside a nice view of the park. Unfortunately these windows didn't seem to have any way of opening. The wall was high, very high, we estimated about 8 meters. On the other side it would give access to the terrace on the first floor. We figured that this would be the perfect entrypoint for our heist. We'd use the cover of darkness to get a ladder across the park, under the trees against that wall. I'd climb over it to land on the terrace and that would be our first step onto the premise. Next step would be to find a way into the building and for that we'd have to find a way to bypass these Suprema fingerprint readers next to every door.

                                                            \n

                                                            So we went back to our hackerspace and researched this device and we figured the best way to move forward would be to actually buy one of these to first try and hack it in the safety of our lab. So I spent a fair amount of time researching the exact model they had installed and ordering one from a local supplier. The thing came at a hefty price, these Suprema devices are not cheap. But now I had an electronic lock, a relay board, a power supply and one of these fingerprint readers with which I could start playing.

                                                            \n

                                                            I started off with reading the manual of course, which already was very interesting on its own. I learned that this thing can be configured in a zillion ways. I figured that, like most things, the guys that installed it would probably stick pretty close to how it came out of the box. So that's what I did as well: I installed the thing exactly as it came, following the instructions in the manual.

                                                            \n

                                                            I'll give you the summary of this entire installation. Electronic locks are pretty simple technology. Basically it's just an electro-magnet, a coil through which you send current to create a magnetic field that pulls a bolt out of the way so the lock can open, that's when it makes the clicking sound. Inside of the building, the receptionist can just press a button and a current will flow to the lock. However, on the outside of the building it wouldn't be very desirable that anyone can just press a button to open the door. That's why most companies implement access controls like RFID-readers or in this case fingerprint readers. A visitor scans his fingerprint with the device next to the door, the software checks if it finds the signature of the print in the database holding all recognized prints, and if so it will open the door.

                                                            \n

                                                            So if we'd want to bypass this scheme, we'd basically have two options: hack the device to open the lock, or duplicate a registered fingerprint to fool the scanner and open the lock. Research had shown that this last option wasn't actually so far fetched. It's actually a proven feasible attack, last DEFCON even demonstrated an attack where a print was copied in 3D using a 3D printer. The technique we would try involved etching the negative of a high-contrast image from a lifted latent print onto a copper plate. Next we'd pour hot glue over that etch to actually recreate the fingerprint in 3D. However, this procedure requires some practice and skills, and we didn't have time for that. We tried it using our own prints lifted from a glass plate, following the procedure as best as we could but we failed miserably. So, this would not be an option and we already spent a fair amount of time.

                                                            \n

                                                            So by now it had become clear we would have to hack the device. And as it was laying there in front of me on my desk, basically running the default setup with just my own print registered in the software, it became obvious that I had missed a crucial error in the design the entire time. I had never actually bothered to install this thing \"properly\" like mounted to a board with its cables fitted nicely behind a wall etc. The entire thing was just laying there, in front of me on my desk and all the cables really were a mess, but most importantly: the software wasn't showing any warnings whatsoever that the device was not mounted to a wall. I investigated the manual and I learned that the thing has something called a \"tamper alarm\". But this must have been disabled by default because I never had any alarms while the device was just laying there and was continuously shaking and moving it. So this meant that I could probably just pull this thing from a wall without any alarms going off.

                                                            \n

                                                            I had to validate this premise first before we could continue. If this turned out to be a false assumption we'd waste valuable time investigating a plan which would probably fail in the end. So the following night I set out again to our clients building. It was like 3:30 in the morning and there was nobody on the streets. We already validated that there were no cameras pointing to the entrance, still I didn't feel too confident. My plan was simple but solid: I'd unscrew the fingerprint reader at the main entrance and put it back in place after 30seconds. I'd then walk to the little square at the end of the street and sit on the bench there so I would have a clear view of our clients entrance. I figured that, if the tamper alarm was enabled, and if they had someone monitoring it, they would probably come and check the device causing the alarm. I'd be interested in their response time of course, but most of all I was just hoping nobody would show up. And that's also what happened. I waited for 2 whole hours on that bench and nobody showed up, so I concluded the tamper alarm must have been disabled as is the default setting on these things, or nobody is monitoring it. Anyway, now I knew I could safely start tinkering on how I could manipulate this thing into letting me.

                                                            \n

                                                            So the next day after I had a few hours of sleep we went back to work, playing with that Suprema BioLite and its software. I was in a good mood and had lots of inspiration. We started with investigating the general architecture of this access control scheme. So it turns out you have a client device, the scanner which is next to the door and this client device gets a database of recognized fingerprints from a control server which holds a list of all connected devices. So it's on this server where you register new doors and locks and new users that can open these locks. Now, when I installed the setup to experiment with, I learned that I had to register the lock into the control server before I could actually do anything, so I followed that entire procedure but unless I was missing something I didn't notice any real checks to be in place during that registration. So what I was thinking was: maybe I can disconnect this device from its network and the control server and reconnect it to my own server. Then I could upload my own prints to the device and then I'd be able to open the door with my own finger. So that's what I tried. I had the entire setup running in my own network, so I re-installed the software once again on my laptop. I then registered another print of mine into this installation. Next I disconnected the device from my network and connected it to a new temporary network running on my laptop: I had it running DHCP and I had a little USB-powered ethernet switch laying around which came in handy for this job. So the device quickly got an ip address from my new network and when I scanned for new fingerprint devices in my network using the Suprema control server that was installed on my laptop, I easily found it and was able to register it in this installation. I then was able to upload a copy of my fingerprints from my laptop to the device and after reconnecting it to the original network I could still open the lock with my newly registered print. So this meant we had our hack to bypass this device: we'd just upload our own set of prints to it and it would happily accept these and open the door for us.

                                                            \n

                                                            So we hired a van and a ladder, and with some action cameras geared up we set out in the middle of the following night. We managed to get the ladder across the park and put it against the wall without making too much noise, we didn't wake up any curious neighbours. Next, I'd climb up the ladder, but since it was only 6m and the wall was about 8m high I'd have to climb the last bit by hand. Fortunately there was some vegetation growing on that wall and it felt like it would be strong enough to hold my weight. So, I gave it a try and pulled myself up from the ladder and the vines fortunately didn't break, so I climbed to the top of the wall and hoisted myself on top of it. I jumped off on the other side and landed on the first floor terrace we saw earlier. I went straight to the door and as expected it had one of these Suprema fingerprint readers next to it and I immediately went to work: I unscrewed the device from its mounting bracket and pulled the cables a bit from the wall. I then cut all the wires of the UTP-connection and connected a female RJ-45 socket to the UTP-wires of the fingerprint reader with crocodile clips. Next I hooked it up to my usb-powered switch which connected the device to the network running on my laptop. As I had tested everything in detail, the attack went smooth as a breeze and within no time I had my own fingerprint loaded into the device. I tested it and I could hear the lock of the door clicking while I put my finger onto the reader, so I started screwing the device back into the mounting bracket.

                                                            \n

                                                            Everything went exactly as planned and I had just put my laptop and all my gear into my backpack again when suddenly I saw the lights go on through the glass door separating me from the inside of the top floor. I could see the elevator doors open and suddenly there I was, standing face to face with a janitor. I could see his face and he could see me so I tried to pull myself together, I had to think quickly. I figured he would let me in, or call the cops and I would probably only get one chance to explain myself. So I pulled my silly face, pointed with a finger to the access control, shrugged my shoulders and lipped slowly \"it's not working\". Well, I must have been an actor in a previous life because, sure thing the man came up to the door and opened up for me. While I entered and said a quick \"hey thanks man\", he looked a bit questioning and mumbled something of \"who are you and what are you doing here?\" and as casual as I could I answered \"Oh I'm from IT, I'm here for work\". I smiled, thanked him once again while I stepped into the elevator and pressed the button for the ground floor. I was in! My heart was pounding like a racehorse but I was in! This stuff was like straight from the movies.

                                                            \n

                                                            Now it was time for the fun part of the night: claiming our flag of victory. First I went to the director's office, to leave a friendly signature of my presence: I left a bottle of champagne on his desk and I decorated the place with some CYBER-tape :-) On my way out I left a little present in the form of a LAN Turtle 3G. That's a 3G-enabled remote access toolkit with a network-connection which I hooked up with an empty socket underneath the receptionist's desk. The LAN Turtle would immediately boot and using its 3G connection it established a reverse tunnel using SSH to our command-and-control server. Using that covert connection we now had a way into the network from the outside. Installing it only took about 15 seconds and after having confirmed tunnel using a shell on my phone I went straight to the front-door and left the place. Mission accomplished! We had successfully penetrated the place.

                                                            \n

                                                            I went to bed with a very big smile on my face early in the morning that day. By Noon I got up after a few hours of sleep and called our clients. They thanked us for the champagne and I gave them the gist of what had happened earlier that day while everyone else was still in bed sleeping.

                                                            \n

                                                            The following weeks we would continue with our assignment and use our newly granted access into the place to go there physically during daytime hours, posing as an external developer. Eventually we gained full access to the entire place, including their on-premise datacenter holding their intellectual property, the crown jewels as to speak. Apparently, the access control-server was still protected with the default credentials admin/admin so I had pretty easy time expanding my initial foothold.

                                                            \n

                                                            At the end of our assignment we presented all of our findings to our client and they immediately took appropriate action, including making sure tampering control got enabled on all of their access control devices. And I for my part had learned a whole lot of new fun stuff about access control devices and the possible flaws they can hold.

                                                            \n

                                                            So, this was yet another story on pentesting and security. I hope you enjoyed this episode. If you'd like to reach out to me, please use the comment section on Hacker Public Radio or contact me on Twitter or Facebook. See you next time!

It is a set of 4 violin concertos that propose an early form of descriptive music: for example, Winter makes prominent use of pizzicato notes in high registers, whereas Summer evokes a storm in its final movement. The work was first presented as part of Op. 8, being later catalogued as RV 269, 315, 293 & 297. The Four Seasons remain very popular to this day, some of its concertos spawning a great number of derivative works, whereas thousands of recordings of the original pieces have been made. It is still debated if Vivaldi wrote this concertos to accompany four sonnets that may have been written by himself.

                                                            \n\n

                                                            We recorded this conversation in the evening of Sunday 23rd August 2020.

                                                            The audio was quite long when we’d finished, so we decided to cut it into two similar-length pieces and the remainder is released as a second episode.

                                                            FreeBSD jails allow users to run multiple, isolated instances of FreeBSD on a single server. Iocage simplifies the management of FreeBSD Jails.

                                                            \n

                                                            The jails will be configured to bind to an IP address on the jail host's internal network. The host OS will pass traffic from the external network to the jail.

                                                            \n

                                                            The jails will be managed with Iocage. Iocage uses ZFS properties to store configuration data for each jail, so a ZFS file system is required.

                                                            1. Set up the internal network.

                                                            PF is full featured firewall, and can do more than just pass traffic to an internal network. Refer to the PF documentation for additional configuration options.

                                                            The best way to use ZFS on a VPS is to attach block storage as a new disk.

                                                            \n

                                                            If block storage is not available, you can optionally use a file as the ZFS device.

                                                            \n

                                                            Enable and start ZFS.

                                                            \n
                                                            sysrc zfs_enable="YES"\nservice zfs start\n
                                                            \n

                                                            ZFS using Block storage

                                                            \n

                                                            List the available disks. If you are using a VPS, the block store will probably be the second disk.

                                                            \n
                                                            geom disk list\n

The goal is to produce a common base Raspberry Pi OS image that doesn't change often but, once it's installed, can automatically be customized, maintained, and managed remotely.\n

                                                            I decided to use my time spent in relative isolation to do something productive and learn another language. I picked Spanish because I am hoping to visit Mexico and other Latin American countries whenever the plague lifts. I decided to document this for anyone who wants to know what options I found and how they have worked for me so far. This is the third part where I explain how I implemented the US International Keyboard on a variety of platforms. This lets me type characters that Spanish uses which do not appear on a standard US English keyboard. And best of all, it a purely free software fix.

In this configuration you can bend the tube to specific angles and make sure the bends stay in plane. The goal here is to create two side rails that are identical. The seat webbing is sewn on to these rails.

The seat backs tie the rails together and are where the clamps that connect the seat to the frame grab the seat. This part of the construction can be overwhelming if you don't take it one step at a time. I had to constantly remind myself that building the bike was not a race but a journey, take your time and enjoy each little milestone. The last picture is the seat frame jigged up and ready for brazing.

This piece connects the back of the seat down to the frame, supporting the upper part of your body. Its made of many parts, but all they are is cut up pieces of steel rod and threaded rod that are brazed together. No bending is involved only cutting and brazing and in the end it wasn't to difficult to fabricate.

                                                            I am out from under my rock, and doing the last of the recumbent bike build episodes. My wife and I are visiting the land of our youth, Colorado, so my recording stuff is at home, hence the espeak rendition of the show. I finished building the bike a while ago and have been riding it around town to do errands and get exercise. I love this bike! The comfort level is unparalleled. Its like sitting in a chase lounge. No more neck strain or pain in the derriere. You don't need any fancy bike clothes, like padded biking shorts, in order to feel comfortable. The bike is fast and has responsive handling. Somethings I have learned so far while riding the bike. First, a rear view mirror really helps when riding on the street. Unlike upright bikes turning your head to look back to clear for traffic is not as easy. Next, the handling takes some getting used to. The long lever arm of the steering tube makes the bike feel jerky when you first ride it. After a while you'll see that a light hand on the tiller goes a long way to smoothing out the ride. It took me a bit of practice to gracefully get the bike started after coming to a stop. Because you can't stand up and hammer on the peddles, coming to a stop requires a bit of work on the gears. Being in a easy gear then shifting up as you get moving is the way to go. If you build one of these bikes, and why wouldn't you, you will have to think about storage because throwing a back pack on is not really an option. I found a bike rack that attaches to the back of the bike, a grocery store plastic basket and an instructive video tutorial by C J Hoyle on you tube took care of my storage needs, a link is in the show notes. The last parts that need to be fabricated to complete the bike were the seat and the handle bars, and all of there associated bits and pieces that make up these assemblies. Instead of narrating through all the pictures, I leave you, dear hacker public radio listener, that's interested to look at the pictures and read the captions yourself. My general impressions of building the pieces are as follows. The handle bars are relatively easy to fabricate but the big problem for me was the metal on the handle bars you use to make the tiller did not braze well with the conduit. In the end I had to resort to pop rivets and a through bolt to get a safe, sturdy connection. The seat is a collection of many parts and at first glance can be a bit overwhelming. By examining the photos on the recycled recumbent website and studying the plans, focusing on each step the seat came out fine for me, yours will too. The side rails are bent using a conduit bender and the challenge is getting the two sides close to match. Take your time and get some extra conduit, you're probably going to need it. The seat back stay is pretty easy to make, but it is made up of quite a few parts, requiring simple cuts and brazing to fashion it. The rest of the seat parts, the various fittings used to clamp the seat to the frame are pretty easy to make and I can't compliment Mr. Carsen highly enough for his ingenious design. Fitting out the bike; getting wheels, brakes and drive train together are going to be unique to every bike and will depend on how much money you want to spend, what parts you have laying around and what fittings you might have to create to attach the parts. I opted to use used parts that were at hand so I could get the bike up and running. I plan on upgrading parts, making changes and improvements after I've ridden the bike for a few months and gotten a good number of miles under my belt. I'll do an update show in the future to let you know what I've done. Will I do this again? Yes definitely I will build another bike, maybe a mach two or three, the building is fun the bike rides great. Mr Carsen sells parts, kits and completed bikes on his website. When I do it again I may opt to buy the seat from him. I would recommend this project to anyone. You can, go out and build one yourself.

                                                            Arc lighting needed a complex mechanism to gradually push the contacts together as they burnt away

                                                            Thomas Edison develop the electric light bulb in 1879 using a carbon filament. It took a great deal of effort to convince people to use it because gas lighting was so well established and worked well.

                                                            Many houses in Britain didn't install electric lighting until the 1930s

                                                            Finally electricity won as it could be used for so many other things.

                                                            The tungsten filament bulb

                                                            \n

                                                            The filament within the bulb is made up of a tungsten coiled coil wire. This is done because the more compactly a filament can be wound the less heat is lost to the surroundings and the brighter the bulb will glow.

                                                            \n

                                                            The tungsten halogen bulb

                                                            \n

                                                            The next progression was tungsten halogen bulb, these bulbs are more efficient and give out twice as much light as ordinary bulbs and usually last twice as long.

                                                            \n

                                                            All filament lights waste a lot of energy producing heat. An ordinary light bulb only gives out 10% of its energy as light, the rest is wasted as heat.

                                                            Fluorescent neon lights

                                                            \n

                                                            Fluorescent neon lights were invented in 1905 by a French man called George Claude. These were used for advertising mainly in America.

                                                            \n

                                                            The first fluorescent light was introduced in 1939 it uses the same principle as the neon light but incorporates a filament at both ends. It is filled with argon and mercury vapour. It mainly gives off ultra violet light the tube is coated on the inside with chemicals to convert the output to mostly visible light using a property called fluorescence.

                                                            \n

                                                            Fluorescent tubes are four times as efficient as normal incandescent light bulbs and run cool.

                                                            \n

                                                            The first energy efficient light bulbs were just fluorescent lights folded into a compact bulb shape.

                                                            Sodium lights used mainly in street lighting are twice as efficient again as fluorescent bulbs they give off a rather horrible orange colour.

                                                            The first commercial high-pressure sodium lamps were available in 1965 from companies in the United States, the United Kingdom, and the Netherlands; at introduction a 400 watt lamp would produce around 100 lumens per watt https://en.wikipedia.org/wiki/Sodium-vapor_lamp

                                                            The next big development was LED lighting which I'll cover in my next episode.

                                                            \n

                                                            The LED or Light Emitting Diode first appeared as a practical electronic component in 1962, the earliest LEDs emitted low-intensity infrared light.[7] Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with high light output. A great deal of development and refinement was required to get to this point.

                                                            The first commercial visible-wavelength LEDs were commonly used as replacements for incandescent and neon indicator lamps, and in seven-segment displays,[31] first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as calculators, TVs, radios, telephones, as well as watches (see list of signal uses). Until 1968, visible and infrared LEDs were extremely costly, in the order of US$200 per unit, and so had little practical use.[32]

                                                            \n

                                                            In 1968 Monsanto was the first organization to mass-produce visible LEDs, these were red LEDs suitable for indicators.[32]

                                                            \n

                                                            In February 1969, Hewlett-Packard introduced the HP Model 5082-7000 Numeric Indicator, the first LED device to use integrated circuit (integrated LED circuit) technology.[33] It was the first intelligent LED display, and was a revolution in digital display technology, replacing the Nixie tube and becoming the basis for later LED displays.[36]

                                                            \n

                                                            The early red LEDs were bright enough only for use as indicators, as the light output was not enough to illuminate an area. Readouts in calculators were so small that plastic lenses were built over each digit to make them legible. Later, other colors became widely available and appeared in appliances and equipment.

                                                            The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines

                                                            In 1973 Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light.[49][50]

                                                            \n

                                                            Today, magnesium-doping of gallium nitride remains the basis for all commercial blue LEDs and laser diodes. In the early 1970s, these devices were too dim for practical use, and research into gallium nitride devices slowed.

                                                            In 1993, high-brightness blue LEDs were demonstrated by Shuji Nakamura of Nichia Corporation using a gallium nitride growth process.[56][57][58] In parallel, Isamu Akasaki and Hiroshi Amano in Nagoya were working on developing the important GaN deposition on sapphire substrates and the demonstration of p-type doping of GaN. This new development revolutionized LED lighting, making high-power blue light sources practical, leading to the development of technologies like Blu-ray[citation needed].

                                                            \n

                                                            Even though white light can be created using individual red, green and blue LEDs, this results in poor color rendering, since only three narrow bands of wavelengths of light are being emitted. The attainment of high efficiency blue LEDs was quickly followed by the development of the first white LED. In this device a cerium doped phosphor coating produces yellow light through fluorescence. The combination of that yellow with remaining blue light appears white to the eye. Using different phosphors produces green and red light through fluorescence. The resulting mixture of red, green and blue is perceived as white light, with improved color rendering compared to wavelengths from the blue LED/YAG phosphor combination.

                                                            The first white LEDs were expensive and inefficient. However, the light output of LEDs has increased exponentially. The latest research and development has been propagated by Japanese manufacturers such as Panasonic, and Nichia, and by Korean and Chinese manufacturers such as Samsung, Kingsun, and others. This trend in increased output has been called Haitz's law after Dr. Roland Haitz.[79]

                                                            Light output and efficiency of blue and near-ultraviolet LEDs rose and the cost of reliable devices fell. This led to relatively high-power white-light LEDs for illumination, which are replacing incandescent and fluorescent lighting.[80][81]

                                                            \n

                                                            Experimental white LEDs have been demonstrated to produce 303 lumens per watt of electricity (lm/w); some can last up to 100,000 hours.[82][83] However, commercially available LEDs have an efficiency of up to 223 lm/w.[84][85][86]

                                                            (Example figures for Halogen bulb being 24 lm / W)

                                                            \n

                                                            With LEDs continuing to get cheaper and even though for now they cost more than traditional bulbs, having this huge increase in electrical efficiency means the overall cost is significantly cheaper than that of incandescent bulbs.[87]

                                                            \n

                                                            While indicator LEDs are known for their extremely long life, up to 100,000 hours, lighting LEDs are operated much less conservatively, and consequently have shorter lives. LED technology is useful for lighting designers, because of its low power consumption, low heat generation, instantaneous on/off control, and in the case of single color LEDs, continuity of color throughout the life of the diode and relatively low cost of manufacture. LED lifetime depends strongly on the temperature of the diode. Operating an LED lamp in conditions that increase the internal temperature can greatly shorten the lamp's life.

                                                            \n

                                                            I now use LED lighting in my own home particularly in the areas where lighting is on for extended periods such as in the living room.

                                                            \n

                                                            As you can see we have come an extremely long way in a relatively short space of time with advancements continuing to accelerate.

                                                            \n

                                                            It's hard to appreciate the massive impact electric lighting has had on the world.

                                                            \n

                                                            It's even harder to imagine living in a time not that long ago where an expensive candle producing a puny amount illumination was the only source of light, with the added not inconsiderable fire risk of having a naked flame sharing a room with combustible materials.

                                                            \n

                                                            With all these deterrents it's little wonder that people just went to bed when the sun went down.

                                                            Social media has some problems, and even federated media is not immune to them. OcapPub proposes to help reduce some problems by moving away from a fundamentally broken model revolving around identity and access to a better model involving objects and capabilities. This could help reduce to problems of identity theft, and help against web site problems like clickjacking and Cross-Site Request Forgery. It is a proposal being worked on, not a finished technology, but it is promising.

I attached the end of the wires to the pipe by stripping the ends and wrapping them around a small 1/2\" self tapping screw. then I screwed one in towards the bottom and on higher up. the one higer up determines when the water alarm goes off. \n

                                                            There are no YAML police. As long as yamllint finds no errors, your YAML is valid and can be parsed by any one of the dozens of YAML libraries out there. However, these YAML libraries aren't magical, so you must understand the internal logic of your own YAML data. Keep that in mind when devising a scheme for the data you're recording.\n

                                                            \n\n

                                                            YAML is a great method for creating configuration files, or storing simple data structures, and it's essential for Ansible playbooks.

                                                            In this show I talk with Apostolos and Vasilis who I met at FOSDEM 2020 about the Pictor radio telescope which they created and now maintain. Using free and open source software and hardware they have made a radio telescope that anyone can operate via a simple web page and which can return results to you within a minute or two. In fact you'll hear me get excited during the show when I realise this and submit an observation request, the results of which came back immediately and which you can see below.

                                                            To date Pictor has performed 3,500 observations from over 700 users from all around the world. Additionally, the PICTOR web platform is now equipped with a 3.2m antenna, which is about 4 times more sensitive than the previous 1.5m antenna, so users can observe the radio sky for free with an even more sensitive instrument.

                                                            \n

                                                            On top of that, after 204 hours of integration time and over 3 TB of data, they have produced a Northern Sky Hydrogen (HI) Survey produced with the PICTOR Radio Telescope. This effort actually marks the very first radio-image obtained in Greece, shown here:

In January 2019, KPN announced that it would eventually phase out the XS4ALL brand and continue operations under the KPN brand. A petition and a special action commission was started to try to revert this decision, the petition has been signed over 50,000 times, signatories include ex-board members and founders of XS4ALL. In November 2019 the committee launched a new company named Freedom Internet, meant to serve as an ideological successor to XS4ALL, and supported by a crowdfunding action that raised 2.5 million euro. Freedom Internet initially offers e-mail hosting, and is meant to roll out its first DSL connections in early 2020.\n

                                                              \n
                                                            • Lists are enclosed in [] and each element is separated by ,

                                                            • Key-value pair lists are enclosed in {} and have the key and value separated by : and each pair is separated by ,
                                                              • \n
                                                            • Keys have to strings quoted with double quotes
                                                              • \n
                                                            • Numbers may be left unquoted (but just in value fields)
                                                              • \n
                                                            \n

                                                            There are no restrictions to what you can do with JSON. Given how explicit the syntax is then, it makes for very easy parsing, and there are plenty of good parser out there. My favourite JSON parser is jq(1).

                                                            \n

                                                            A canonical representation of the JSON example above can easily be obtained with jq by simply calling jq '' file.json (or piping the file through stdin, or even putting the contents properly quoted as the second argument).

                                                            \n
                                                            {\n  "first list": [\n    "element1",\n    "element2",\n    {\n      "element3": "is another k-v pair",\n      "but contains": [\n        "a",\n        "list",\n        "of",\n        "words"\n      ]\n    }\n  ],\n  "this value is a string": "1",\n  "and this is a number": 23,\n  "and floating point": 1.413\n}
                                                            \n

                                                            You can also use jq in a shell script to obtain, for example the second element of the first list:

                                                            \n
                                                            $ jq '."first list"[1]' example.json\n"element2"
                                                            \n

                                                            So to get the value associated to a key you use the notation .key and to get the k-th element you use the notation [k-1]. To remove the quotes on the string you can use the -r flag which stands for raw output.

                                                            \n

                                                            jq(1) also gives you a few more functionalities that can be useful like getting the number of elements in a list with the length function.

                                                            \n
                                                            $ jq 'length'  example.json\n3\n$ jq '."first list"[2]."but contains" | length'\n4
                                                            \n

                                                            Another useful feature is getting the list of keys from a key-value pair list which can be done with the function keys

                                                            \n
                                                            $ jq '."first list"[2] | keys[]' example.json\n"but contains",\n"element3"
                                                            \n

                                                            The query language is much much more flexible than this, but for most cases this should be enough for simple configuration querying.

                                                            \n

                                                            YAML and XML??

                                                            \n

                                                            The yq project allows one to use the exact same syntax as jq to query, and emit (and therefore also transcode) yaml and XML, extending the usefulness of the query language.

                                                            \n

                                                            So for example looking at the previous file through yq gives:

                                                            \n
                                                            $ yq -y '' example.json\nfirst list:\n  - element1\n  - element2\n  - element3: is another k-v pair\n    but contains:\n      - a\n      - list\n      - of\n      - words\nthis value is a string: '1'\nand this is a number: 23\nand floating point: 1.413
                                                            \n

                                                            And the output of this can be of course queried with yq itself, or can be used to feed into whatever application requires a yaml input (I guess it lacks the triple dash at the top, but that is actually the only warning I get from passing that abomination to yamllint)

                                                            \n

                                                            Similarly xq can be used to query XML files with the same language. However, to emit these files from json you need to use yq -x like so:

                                                            \n
                                                            $ yq -x '' example2.json\n<file>\n  <first_list>element1</first_list>\n  <first_list>element2</first_list>\n  <first_list>\n    <element3>is another k-v pair</element3>\n    <but_contains>a</but_contains>\n    <but_contains>list</but_contains>\n    <but_contains>of</but_contains>\n    <but_contains>words</but_contains>\n  </first_list>\n  <this_value_is_a_string>1</this_value_is_a_string>\n  <and_this_is_a_number>23</and_this_is_a_number>\n  <and_floating_point>1.413</and_floating_point>\n</file>
                                                            \n

                                                            where the original (modified) file example2.json looks like:

                                                            \n
                                                            {\n    "file":\n    {\n      "first_list": [\n        "element1",\n        "element2",\n        {\n          "element3": "is another k-v pair",\n          "but_contains": [\n            "a",\n            "list",\n            "of",\n            "words"\n          ]\n        }\n      ],\n      "this_value_is_a_string": "1",\n      "and_this_is_a_number": 23,\n      "and_floating_point": 1.413\n    }\n}
                                                            \n

                                                            So that the root dictionary has a single key-value pair and all the keys have no spaces in them (so that they can be made into xml tags).

                                                            \ni.e., data is aligned in a tabular fashion in rows and columns. Think of a spreadsheet type object in memory\n

                                                            The ReText website on GitHub says that ReText is a simple but powerful editor for Markdown and reStructuredText markup languages.

                                                            \n

                                                            Doing a search on the HPR site returned the following two references to ReText.

                                                            \n

                                                            The excellent Markdown and Pandoc HPR 1832 episode by Mr. Young makes reference to ReText

                                                            Dave Morriss mentioned using ReText as a possible tool when sending in shownotes as markdown is preferable to plain text. Refer to HPR 3167

                                                            \n

                                                            As of the 1st of January 2021 I am running ReText version 7.0.1 the latest version was 7.1.0 this was last updated on the 4th of April 2020.

                                                            Why I am covering this

                                                            \n

                                                            I’m covering this because in HPR show 3167 Dave Morriss said that Markdown was a preferred way to submit shownotes. Prior to this I had supplied my shownotes in plain text.

                                                            \n

                                                            What is Markdown?

                                                            \n

                                                            I guess I first must cover what markdown is I found the following definitions:-

                                                            \n

                                                            Markdown is a lightweight markup language for creating formatted text using a plain-text editor. John Gruber and Aaron Swartz created Markdown in 2004 as a markup language that is appealing to the human users in its source form.[9] Markdown is widely used in blogging, instant messaging, online forums, collaboration software, documentation pages, and even readme files Link https://en.wikipedia.org/wiki/Markdown

                                                            Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

                                                            • Using ReText to pull these shownotes together disciplined me to hopefully put more meaningful titles within my shownotes.

                                                            • It helped my to create meaningful descriptive links which will hopefully help accessibility for the visually impaired.

                                                            • I edited the text on this occasion in live preview mode I found this made it very easy to see how the final version would look.

                                                              • \n

                                                            • I think I ended up with more polished shownotes that hopefully needs fewer and hopefully no input from our band of HPR volunteers working behind the scenes.

                                                            In preparation for doing some sample exercises I wanted to first explain about how you can use images and fonts that are not restricted or are available under license terms that are not too restrictive. Any image that is intended for public display or for commercial purposes could be liable for copyright infringement if care is not taken. Fortunately, there are many resources available that you can use, and we look at some of the better ones.

                                                            Introduction

                                                            \n

                                                            I noticed nagios on the requested topics page. I am far from being an expert with nagios and there is a lot I do not know. I have a working knowledge of most of the basic nagios principles. So, hopefully, I can give a useful introduction and review some one the principles of nagios along the way

                                                            \n

                                                            Nagios is a network monitoring tool. You define some things for nagios to check, and nagios will alert you if those checks fail.

                                                            \n

                                                            Nagios has a web UI that is normally used to see the status of the checks. There are some basic administration tasks you can do from the web UI

                                                            • enabling/disabling notifications
                                                              • \n
                                                            • Scheduling Downtime
                                                              • \n
                                                            • Forcing immediate checks
                                                              • \n
                                                            \n

                                                            Nagios is primarily configured with text files. You have to edit the nagios config files for things like

                                                            \n
                                                              \n

                                                            Nagios core vs NagiosXI

                                                            \n

                                                            NagiosXI is the commercial version of nagios. NagiosXI requires a paid license and includes support. NagiosXI has some extra features including wizards for adding hosts and easy cloning of hosts.

                                                            \n

                                                            I have used NagiosXI, and personally don't find the extra features very useful. Probably the biggest reason to use NagiosXI is Enterprise that requires commercial support

                                                            \n

                                                            The community version of nagios is normally referred to as nagios core This episode will focus on the nagios core

                                                            \n

                                                            Nagios Documentation

                                                            \n

                                                            I don't like the official nagios core documentation. A lot like man pages, It is a good reference, but can be hard to follow.

                                                            \n

                                                            Maybe is it possible for someone to read the documentation and be able to install and configure nagios for the first time. But it took me a lot of trial and error to get a functional nagios server following the nagios documentation

                                                            \n

                                                            Outside of the official documentation, Most of the nagios installation guides I found online recommend downloading and building nagios from the nagios site. My general policy is to use OS provided packages whenever possible. Normally, sticking to packages eases long the term maintenance.

                                                            \n

                                                            You may not always get the latest feature release, but installation and updates are usually easier. I know not everyone will agree with me here, and will want to build the latest version. Regardless of the install method, most of the nagios principles I go over will still apply

                                                            \n

                                                            I am making the assumption that most listeners will be most familiar with Debian/Ubuntu, so I will go over installing nagios on Ubuntu using the nagios packages from the Ubuntu repository

                                                            \n

                                                            Hosts and Services

                                                            \n

                                                            Before I go over the installation, I'll talk a bit about some of the pieces that make up nagios Nagios checks are for either hosts or services.

                                                            \n

                                                            From the Nagios documentation

                                                            \n
                                                            \n

                                                            A host definition is used to define a physical server, workstation, device, etc. that resides on your network.

                                                            \n
                                                            \n

                                                            Also from the nagios documentation

                                                            \n
                                                            \n

                                                            A service definition is used to identify a \"service\" that runs on a host. The term \"service\" is used very loosely. It can mean an actual service that runs on the host (POP, SMTP, HTTP, etc.) or some other type of metric associated with the host

                                                            \n
                                                            \n

                                                            Normally, hosts are checked using ping. If the host responds to the ping with in the specified time frame, the host is considered up. Once a host is defined and determined to be UP, you can optionally check services on that host

                                                            \n

                                                            Installation and setup

                                                            \n

                                                            Install the packages

                                                            \n
                                                            apt install nagios4
                                                            \n

                                                            One of the dependencies is the monitoring-plugins I'll talk more about the monitoring-plugins package when we dig in to the checks

                                                            \n

                                                            The primary UI for nagios is a cgi driven web app usually served via apache. Following the nagios4 installation, the web UI isn't functional. So we need to make a few configuration changes

                                                            \n

                                                            The nagios config file for apache contains a directive that is not enabled by default

                                                            \n

                                                            Enable 2 Apache modules

                                                            \n
                                                            a2enmod authz_groupfile\na2enmod auth_digest\nsystemctl restart apache2
                                                            \n

                                                            Nagios authentication

                                                            \n

                                                            Enable users in the nagios UI

                                                            \n

                                                            In /etc/nagios4/cgi.cfg change the line

                                                            \n
                                                            'use_authentication=0'
                                                            \n

                                                            to

                                                            'use_authentication=1'
                                                            \n

                                                            Modify Apache

                                                            \n

                                                            In /etc/apache2/conf-enabled/nagios4-cgi.conf change

                                                            \n
                                                            Require all granted
                                                            \n

                                                            to

                                                            \n
                                                            Require valid-user
                                                            \n

                                                            And if needed, remove the IP restriction by removing the line that starts with

                                                            \n
                                                            Require ip
                                                            \n

                                                            And finally we need to add a nagios basic auth user. I normally use nagiosadmin, but it can be any username

                                                            \n
                                                            htdigest  -c /etc/nagios4/htdigest.users Nagios4 nagiosadmin
                                                            \n

                                                            Restarts

                                                            \n

                                                            Restart apache and nagios and the nagios UI will be fully functional

                                                            \n

                                                            \n

                                                            Nagios uses a collection of small standalone executables to perform the checks. Checks are either OK, Warning, or Critical, depending on the exit code of the check.

                                                            The check commands are standalone applications that can be run independent from nagios. Running the checks from the shell is helpful to better understand how the nagios checks work. The location of the check commands can vary depending on how nagios was packaged. In this case, they are in /usr/lib/nagios/plugins

                                                            \n

                                                            Looking at the names on the files can give you an idea of their purpose. For example, it should be obvious what check_http and check_icmp are for.

                                                            \n
                                                            cd /usr/lib/nagios/plugins\n$ ./check_icmp localhost\nOK - localhost: rta 0.096ms, lost 0%|rta=0.096ms;200.000;500.000;0; pl=0%;40;80;; rtmax=0.218ms;;;; rtmin=0.064ms;;;;\n$ ./check_http localhost\nHTTP OK: HTTP/1.1 200 OK - 10977 bytes in 0.005 second response time |time=0.004558s;;;0.000000;10.000000 size=10977B;;;0
                                                            \n

                                                            Most checks can be run with -h to print usage help

                                                            \n

                                                            The checks can be in any language as long as is it is executable by the nagios server. Many are compiled C but Perl and shell scripts are also common

                                                            The primary nagios config file is /etc/nagios4/nagios.cfg

                                                            nagios.cfg has a directive that will load additional user generated files

                                                            I like to put all my additions to nagios in this directory and use git for both version control and backup.

                                                            \n

                                                            Nagios doesn't run the check executable directly The checks have to be explicitly defined in as a command Some predefined commands are in /etc/nagios4/objects/commands.cfg

                                                            \n

                                                            Debian package monitoring-plugins-basic contains several command definitions that are loaded by nagios.cfg cfg_dir=/etc/nagios-plugins/config

                                                            \n

                                                            Lets look in the /etc/nagios-plugins/config at ping.cfg for an example of how commands are defined

                                                            \n
                                                            # 'check-host-alive' command definition\ndefine command{\n    command_name    check-host-alive\n    command_line    /usr/lib/nagios/plugins/check_ping -H '$HOSTADDRESS$' -w 5000,100% -c 5000,100% -p 1\n    }
                                                            \n

                                                            Commands require command_name and command_line The command line is that path to the executable that will perform the check and optional arguments. Most checks require -H for the host address to check The check-host-alive command also contains arguments to set the critical and warning thresholds with -c and -w

                                                            \n

                                                            The check_ping command is similar the check-host-alive command except it requires 2 arguments to set the critical and warning thresholds.

                                                            \n
                                                            define command{\n        command_name    check_ping\n        command_line    /usr/lib/nagios/plugins/check_ping -H '$HOSTADDRESS$' -w '$ARG1$' -c '$ARG2$'\n        }
                                                            \n

                                                            Templates

                                                            \n

                                                            Hosts and services require a lot of reused variables. Object definitions normally use templates to avoid having to repetitively set the same variables on each host. Nagios normally ships with predefined templates for hosts and services that will work for most cases.

                                                            \n

                                                            In Ubuntu, the templates are defined in /etc/nagios4/objects/templates.cfg. Template definitions are the same as other object definitions, except they contain register 0 which designates the object as a template. I'll show how the templates are used when I go over the host and service definitions.

                                                            \n

                                                            Notifications

                                                            \n

                                                            By default, notifications are sent via email to nagios@localhost. The easiest way to get notifications is to configure the nagios server to forward emails to a monitored email address. Since many networks block sending email directly via SMTP, email forwarding may be challenging.

                                                            \n

                                                            In a follow up episode I will cover setting up postfix to relay mail through a mail sending service and maybe some other methods for sending alerts

                                                            \n

                                                            Localhost

                                                            \n

                                                            By default, nagios is set to monitor localhost. Having the nagios server can be useful but you probably want to add some additional servers.

                                                            \n

                                                            Have a look at /etc/nagios4/objects/localhost.cfg if you want to see how the checks for localhost are defined

                                                            \n

                                                            Adding a new host to monitor

                                                            \n

                                                            We will use google.com as an example and create a file named google.cfg and place it in in the cfg_dir /etc/nagios4/conf.d.

                                                            \n

                                                            The files can be named anything that ends in .cfg. My preference is one file per host that contains all the checks for that host. The content of google.cfg is included new the end of the show notes.

                                                            \n

                                                            First, we need to define the host. host_name is the only field required to be set. The remaining requirements are met by using the generic-host template.

                                                            \n

                                                            We can add a service check to google.com using the same file. The easiest to add is a http check host_name, service_description, and check_command have to be set the remaining requirements are met by using the generic-service template.

                                                            \n

                                                            Restarting Nagios

                                                            \n

                                                            Nagios has to be reloaded to pick up the configuration changes. Prior to restarting nagios, you can verify the nagios configuration is valid by running:

                                                            \n
                                                            nagios4 -v /etc/nagios4/nagios.cfg
                                                            \n

                                                            This will print a summary of the configuration. Any warnings or errors will be printed at the end.

                                                            \n

                                                            Warnings are not fatal, but should probably be looked at. Errors will keep nagios from restarting; if there are no errors, it is safe to restart nagios

                                                            \n

                                                            Check the nagios UI at https://SERVER_IP/nagios4 and you should see 2 hosts, localhost and google.com as well as the service checks for the hosts

                                                            On January 5, 2021, Zen_Floater2 did an interesting show that you might call a virtual conversation with Klaatu. He took a show that Klaatu had done on the GNU World Order podcast about using Chromebooks, and interspersed his own comments. As I was listening I thought that I had a slightly different perspective, so I recorded this brief show about my own experience.

                                                            Upgraded my raspberry pi 13, which I think had a minimal install Raspbian, Debian i.e. has no desktop installed. The Pi had a PiFaceIO board installed, refer to my previous HPR episode Hpr2901

                                                            \n

                                                            Backup process, in case something went wrong

                                                            \n

                                                            I first moved all the unnecessary files to free up as much space as possible

                                                            \n

                                                            Shrunk the Pi partition on the installed 128GB SD card down to 25106MB (24.52GB), (25708544K), 26,325,549,056 bytes using partition magic

                                                            \n

                                                            I calculated that this would be 51,417,088 blocks of 512 bytes

                                                            \n

                                                            I used dd to make an image file and grabbed some unallocated space after partition by using count=55417088, refer to the command below

                                                            \n
                                                            sudo dd if=/dev/sdb of=/home/stuart/pi-13-img-backup.img bs=512 count=55417088
                                                            \n

                                                            I used the following command to image files to a spare 64GB SD card

                                                            \n
                                                            sudo dd if=/home/stuart/pi-13-img-backup.img of=/dev/sdb bs=512 status=progress
                                                            \n

                                                            I then expanded the partition to fill the full 64GB of the card

                                                            \n

                                                            Booted from the 64GB card to make sure that I had a backup in case anything went wrong

                                                            \n

                                                            Removed the 64GB card which I can go back to if things don't work out

                                                            \n

                                                            Booted from 128GB card and expanded the partition using Gparted to fill 128GB SD card

                                                            \n

                                                            I used the 128GB SD card to perform the upgrade, remember I have 64GB card to fall back on if things go wrong

                                                            \n

                                                            Upgrade process

                                                            \n

                                                            Source of information below

                                                            \n

                                                            Step 1: Check available disk space

                                                            \n

                                                            In order to update to Raspbian Stretch, there must be enough space on the SD card. Therefore you should check the available and used disk space usage first:

                                                            \n
                                                            $ df -h
                                                            \n

                                                            Step 2: Check package status

                                                            \n

                                                            You must also check that all packages are in a state that is suitable for upgrade. The following command displays all packages that have the status semi-installed or configuration failed, and those with error status:

                                                            \n
                                                            $ sudo dpkg --audit\n$ sudo dpkg --get-selections | grep hold
                                                            \n

                                                            Step 3: Update system

                                                            \n

                                                            Before upgrading, the Raspbian should be completely updated:

                                                            \n
                                                            $ sudo apt-get update\n$ sudo apt-get upgrade\n$ sudo apt-get dist-upgrade
                                                            \n

                                                            Step 4: Modify Release

                                                            \n

                                                            For upgrading to the new Raspbian version, the package lists must be adapted to the \"Stretch\" release. To do this, only the word \"jessie\" has to be replaced by \"stretch\". In order not to overlook any position, we simply let the replacement be done by the following command:

                                                            \n
                                                            $ sudo sed -i /deb/s/jessie/stretch/g /etc/apt/sources.list\n$ sudo sed -i /deb/s/jessie/stretch/g /etc/apt/sources.list.d/*.list
                                                            \n

                                                            Step 5: Updating package lists

                                                            \n

                                                            The new package lists must then be updated and imported:

                                                            \n
                                                            $ sudo apt-get update
                                                            \n

                                                            Step 6: Update to \"Stretch\"

                                                            \n

                                                            Now we are ready to start the upgrade:

                                                            \n
                                                            $ sudo apt-get upgrade\n$ sudo apt-get dist-upgrade
                                                            \n

                                                            Step 7: Clean up installation

                                                            \n

                                                            Old, unnecessary packages are removed after the system update with the following commands:

                                                            \n
                                                            $ sudo apt-get autoremove\n$ sudo apt-get autoclean
                                                            \n

                                                            What was reported during upgrade

                                                            \n

                                                            repo for get_iplayer no longer available so had to comment them out. On my Pi these were located at the following location.

                                                            change to lsb_release command

                                                            \n

                                                            The lsb_release command no longer worked so after the upgrade I could not use it to check what version of Debian I was running.

                                                            \n

                                                            I chose the following method

                                                            \n

                                                            .bashrc - kept my original file

                                                            \n

                                                            Something about /etc/login.defs & /etc/login.defs.dpkg-new

                                                            \n

                                                            lots of changes in new version of ssh

                                                            Something was mentioned about apt hashes sha1 weak \"yes\" & apt hashes ripe-md/160 weak \"yes\"

                                                            \n

                                                            Something about ~/.ssh/authorized_keys & ~/.ssh/authorized_keys2

                                                            \n

                                                            Something about key length and accepted key types

                                                            \n

                                                            What went wrong after the upgrade

                                                            \n

                                                            mocp wouldn't run

                                                            \n

                                                            I had to modify my config file in .moc folder I added the following line near the top of the file

                                                            \n
                                                            ALSAStutterDefeat = no
                                                            \n

                                                            In my .moc folder I had to also modify the my_keymap file at line 82. I think the next_search option is not available in the new version of moc 2.6-alpha3 installed with Debian Stretch. I commented out the following

                                                            \n
                                                            #next_search =          ^g ^n
                                                            \n

                                                            pifacedigitalio test.py reported an error

                                                            \n

                                                            multiple errors reported last line of error was:-

                                                            \n
                                                            pifacedigitalio.core.NoPiFaceDigitalDetectedError: No PiFace Digital board detected (hardware_addr=0, bus=0, chip_select=0)
                                                            \n

                                                            I changed the first line of my python script

                                                            \n

                                                            from

                                                            \n
                                                            #!/usr/bin/env python
                                                            \n

                                                            to

                                                            \n
                                                            #!/usr/bin/env python3
                                                            \n

                                                            This removed the original error. I stupidly thought this had solved the problem so I went about converting my script to run with Python 3 only to find at the end once I had correct everything that I ended up with the same original error.

                                                            \n

                                                            How I solved the pifacedigitalio test.py reported error

                                                            \n

                                                            The problem was solved by looking at this post

                                                            \n

                                                            According to the post it had something to do with the SPI serial speed changing from 500Khz to 125Mhz

                                                            \n

                                                            Problem was solved by modifying a file spi.py

                                                            \n

                                                            I found the location of the file by using the following command

                                                            \n
                                                            find / -iname spi.py
                                                            \n

                                                            The files were located at

                                                            \n
                                                            /usr/lib/python2.7/dist-packages/pifacecommon/spi.py\n/usr/lib/python3/dist-packages/pifacecommon/spi.py
                                                            \n

                                                            I created a copy of the original file and called it spi.py.bak

                                                            \n

                                                            I only modified the file in python2.7 as my program test.py runs in python2.7

                                                            \n

                                                            I added a comma to the end of line 68 and added the following line to line 69

                                                            \n
                                                            speed_hz=ctypes.c_uint32(15000)
                                                            \n

                                                            SSH from pifacecad stopped working

                                                            \n

                                                            My Raspberry pi \"Pi10\" downstairs would not SSH into my Pi13 server upstairs This made it impossible for me to remotely start and stop podcasts and audiobooks playing on my Pi13 upstairs.

                                                            \n

                                                            This happened because the downstairs Pi10 had DSA and RSA keys and it was using DSA keys to ssh into Pi13. I found this by looking at /var/logs/auth.log on Pi13 The log reported

                                                            \n

                                                            Was not able to SSH into Pi13 from EEEpc

                                                            \n

                                                            My EEEPC netbook only had DSA keys and that is what it was using to try and SSH into Pi13 I generated new RSA keys and added them to Pi13, this solved the problem and allowed me to ssh into Pi13 from the EEEpc

I chose to do a header image for my site Ahuka Communications that would more accurately reflect the content. This lets us use freely licensed images, an OFL-licensed font, layers, and various tools. Note that you can download all of this stuff from my site.

                                                            In the intervening time I looked at several solutions to improve this situation.

                                                            \n

                                                            The most obvious step was to put a magnetic switch on the scanner lid so that a device could detect the lid been closed.

                                                            \n

                                                            I tried a Raspberry PI but my scanner drivers are only available for Intel and not Arm. Then then accessing the pi using Remote GPIO, but it got very complex to setup and run.

                                                            \n

                                                            Inspired by hpr3077 :: Video conference Push to Talk Hosted by DanNixon on 2020-05-19, I tried using an arduino talking over serial to a Intel Compute Stick. But that was very flakey.

                                                            \n

                                                            Finally I settled on using a Clone of LOLIN D1 mini, and some Reed Contacts.

                                                            Wire one end of the reed contact to 3.3v, and the other end to ground via a 10K resistor.

                                                            Have a sensor wire go from the 10K resistor to pin D5 on the D1 Mini.

If you found its 16GB of storage wasn't enough, you were supposed to dump it and buy a new one as you couldn't add more. If you found that you couldn't run the latest version of your favourite apps, dump it and buy a new one as you couldn't upgrade the operating system to the required standard.

This time I used mc \"Midnight Commander\" to copy the files back which I found much easier than using the GUI file manager the first time around. Midnight commander is an Ncurses file manager.

                                                            • Midnight Commander gave a constant percentage progress of each individual file being copied and the overall progress which was very useful and reassuring with such a slow laptop. The first time around the laptop actually crashed a couple of times when I was using the LUBUNTU GUI file manager to try and copy the files from the laptop to the hard drive.

                                                            • Also even though I generally use keyboard shortcuts for copy and paste operation I still tend to use the track pad at places when using a file manager. It's easy to limit yourself to keyboard navigation using mc. I found this to be greatly reassuring and I feel doing this makes the likelihood of disastrous errors much less likely.

                                                            Wireguard How To

                                                            \n

                                                            Firstly, I am not an expert. These are just my findings setting up wireguard at home and in my office at work.

                                                            \n

                                                            I've used a program called sshuttle for 7/8 years to attach myself to my home and work networks when on public/untrusted networks or if I need to access some resource at work from home.

                                                            \n

                                                            Sshuttle for the main part works great and the main benefit is that the only port you ever need to open on the server network is whichever port you have your ssh server running on.

                                                            \n

                                                            The downside to sshuttle is that it won't work with my android devices so I've been using a paid for VPN called PIA on untrusted networks or just staying on 3g/4g and not have any way to connect to my home or work network.

                                                            \n

                                                            Sshuttle is written in python and a few weeks ago Arch Linux moved to python 3.8 which broke sshuttle. There is a workaround using pyenv and a bug has been filled with the python team and a it's already been fixed upstream https://bugs.python.org/issue35415.

                                                            \n

                                                            Anyway.

                                                            \n

                                                            I thought it was about time I looked at setting up a proper VPN on my work network.

                                                            \n

                                                            So I spent a couple of hours reading up on openVPN and creating client and server certificates making a server config on the work server forwarding the port on the router to the server.

                                                            \n

                                                            Then I spent a couple more hours poking around trying to figure out why it wouldn't work.

                                                            \n

                                                            I eventually gave up frustrated.

                                                            \n

                                                            I'm not blaming openVPN, I know it works for many many people, but I couldn't see what was wrong.

                                                            \n

                                                            So I did what we all do in a situation like this.

                                                            \n

                                                            I took to social media, which in my case is my pleroma server and posted a message to the fediverse.

                                                            \n

                                                            \"OpenVPN has fried my brain. Need booze\"
                                                            \nThen I had a beer, a nice cold Stiegl goldbrau if I remember right.

                                                            \n

                                                            A few minutes later a message popped up from theru, it contained one word with a smiley face. Wireguard.

                                                            \n

                                                            Now I had looked at wireguard a while ago. You might remember it hit the headlines because Linus Torvalds had praised how beautifully written the code was for it. It turns out what he said was \"It's beautiful when compared to openVPN's code\". Back then the how to guides were really hard, for me anyway to follow.

                                                            \n

                                                            There were just examples of two machines on the same LAN connected together and I really struggled to get my head around it being serverless and both machines being peers to each other; after all openVPN has clients and servers and even sshuttle on my laptop connects to a server machine.

                                                            \n

                                                            There where a couple of wiki pages that I read on Christmas Eve that gave me a lightbulb moment and some clarity on the way it worked. So I decided to try and set it up.

                                                            \n

                                                            The articles acknowledge that it is a peer to peer technology and then go on to call one peer a server and the other peer the client.

                                                            \n

                                                            Also I would recommend for your first client use an android device with the wireguard app. It's more user friendly in that some of the config is auto filled for you and then you can export the config file and examine it in a text editor later to get a better handle on things.

                                                            \n

                                                            I'm going to assume that you have installed the wireguard packages for your system and that you have given your server a static IP on your network.

                                                            \n

                                                            I'm using Arch linux on my servers but I see the Linode Debian 'how to' works in the same way.

                                                            \n

                                                            So we are going to log into the server and start the setup.

                                                            \n

                                                            Create/edit wireguard config

                                                            \n

                                                            Check the interface name facing the internet is correct before copy/paste

                                                            \n
                                                            ifconfig
                                                            \n

                                                            Before you continue you will need to forwrd a port from your internet facing router to your server. Somewhere in your router settings you'll find a port forward setting. At home I have a Fritzbox and it's buried under network / permitted access. At work it's a Linksys ac1200 and it's under gaming / apps / single port forwarding. I'm sure you will find it.

                                                            \n

                                                            The wireguard default port is 51820 and you'll find this port named in most of the how to's on the web. I use a different port number just to add a little bit of obsurity/security to my setup so if you choose to forward a different port from your router then remember to use that number in the configs.

                                                            I want to install NextCloud for my family, but only for my family. This means making things hard for myself by installing it behind my firewall with a private nat ipaddress. That presented problems with getting a valid Let's encrypt cert.

                                                            \n

                                                            It all now works, and thanks to timttmy I was able to get the WireGuard VPN installed and working.

                                                            Get a Pi, and a SSD, enable it. You should review Raspberry Pi 4 USB Boot Config Guide for SSD / Flash Drives, for issues with SSD drives and the Raspberry Pi.

                                                            You can install Raspbian as normal. I already covered this in hpr2356 :: Safely enabling ssh in the default Raspbian Image, and Safely enabling ssh in the default Raspberry Pi OS (previously called Raspbian) Image.

                                                            \n

                                                            And then follow the instructions in How to Boot Raspberry Pi 4 From a USB SSD or Flash Drive.

                                                            I got an error \"Error occurred while checking server setup\". I used this tip to move root owned files out of next cloud dir.

                                                            For me it was mostly about enabling caching via APCU, and enabling You are accessing this site via HTTP.

                                                            Setting up Apache is not well explained anywhere I could find.

                                                            Now that everything is up and running we just need to create a new A record pointing to our internal IP Address. Unfortunately while nextcloud.example.com resolves to 192.168.123.123 externally, it fails to return an answer internally.

                                                            \n

                                                            A little investigation lead to the fact that my firewall, was seeing this as a DNS Rebinding attack. It correctly blocks these DNS entires. I was able to add an exception under Network > DHCP > Rebind protection > Discard upstream RFC1918 responses.

                                                            \n

                                                            On your router you should check under DHCP/DNS entries for RFC1918 or DNS Rebinding.

                                                            \n

                                                            I cheated and used the PIVPN which now supports wireguard.

                                                            \n

                                                            This is a good walkthrough with screenshots in the article Setting up a WireGuard VPN on the Raspberry Pi.

                                                            Once that's done you should have the following commands available.

                                                            \n
                                                            # pivpn\n::: Control all PiVPN specific functions!\n:::\n::: Usage: pivpn <command> [option]\n:::\n::: Commands:\n:::  -a,  add              Create a client conf profile\n:::  -c,  clients          List any connected clients to the server\n:::  -d,  debug            Start a debugging session if having trouble\n:::  -l,  list             List all clients\n:::  -qr, qrcode           Show the qrcode of a client for use with the mobile app\n:::  -r,  remove           Remove a client\n:::  -h,  help             Show this help dialog\n:::  -u,  uninstall        Uninstall pivpn from your system!\n:::  -up, update           Updates PiVPN Scripts\n:::  -bk, backup           Backup VPN configs and user profiles\n
                                                            \n

                                                            During the install process you will select a port to use. This port needs to be allowed in from the Internet to your internal server. Where this will be done is different for every router, but have a look around for port forwarding or permit access to do this.

                                                            \n

                                                            It is at this point that you will need to have accounts created in NextCloud.

                                                            \n\n

                                                            You can do this under your profile > users in an admin account.

                                                            \n

                                                            I created an account for each of the family members, a generic one for the house, and a readonly one for the MagicMirror.

                                                            \n

                                                            The house account houses (pun intended) the shared calendar, files, and contacts. All the family accounts have read and write access to these, except for the MagicMirror one which only needs to read the calendar and contacts.

                                                            You will need to setup the NextCloud client using the url https://nextcloud.example.com/nextcloud/, username and password.

                                                            Then you set up DAVx using another url https://nextcloud.example.com/nextcloud/remote.php/dav, but the same , username and password.

                                                            By the way if you want to access files you can do so via davs://nextcloud.example.com/nextcloud/remote.php/dav/files/house/

                                                            \n

                                                            I set up the NextCloud client to automatically upload photos, and videos to the server.

                                                            \n

                                                            To set up WireGuard you need to create a connection for each device connecting

                                                            \n

                                                            Open the WireGuard app on the phone and press + to add an account, and select scan from qr code.

                                                            MagicMirror

                                                            \n

                                                            The final step is to have the MagicMirror in the living room display the shared calendar.

                                                            \n

                                                            To display your calendar there, you need to have an ics iCalendar file.

                                                            \n

                                                            You can get that by login into NextCloud as the MagicMirror user via the web, going to the calendar you desire to export. Click the ... menu and select \"Copy Private Link\".

                                                            \n

                                                            You can then add the ?export at the end of the url to get an ical export.

                                                            \n

                                                            Dave gave me a tip on how to have MagicMirror serve this file, by using its own local webserver. You point it to a local directory eg: https://localhost:8080/modules/.calendars/. Don't forget to create it.

                                                            \n
                                                            mkdir -p ~/MagicMirror/modules/.calendars/
                                                            \n

                                                            I wrote a script that would first get a new version of the ical file, and if it is downloaded correctly would immediately overwrite the previous one.

                                                            \n
                                                            [magicmirror@magicmirror ~]$ cat /home/pi/bin/cal.bash\n#!/bin/bash\nwget --quiet --output-document /home/pi/MagicMirror/modules/.calendars/home_calendar.ics.tmp --auth-no-challenge --http-user=magicmirror --http-password="PASSWORD" "https://nextcloud.example.com/nextcloud/remote.php/dav/calendars/magicmirror/personal_shared_by_House/?export" > /dev/null 2>&1\nif [ -s /home/pi/MagicMirror/modules/.calendars/home_calendar.ics.tmp ]\nthen\n  mv /home/pi/MagicMirror/modules/.calendars/home_calendar.ics.tmp /home/pi/MagicMirror/modules/.calendars/home_calendar.ics\nfi\n[snip...]
                                                            \n

                                                            I then scheduled this to run every 15 minutes.

                                                            \n

                                                            The final step was to update my Calendar entry in the ~/MagicMirror/config/config.js config file.

                                                            \n

                                                            The contacts birthday wasn't available to the MagicMirror user immediately after I created it, so I was able to force an update as follows:

                                                            In this episode of Hacker Public Radio, I will describe the method I chose to combat spam bots filling out my company's contact form. About 99% of the submissions we receive are spam, which makes filtering for valid messages painful. After some research into different methods, I decided to go with the honey pot method.

                                                            \n

                                                            The honey pot method uses an extra text input field to lure the spam bot into filling it out. There are different suggestions for how to hide this extra field from valid users by using either javascript or CSS. With javascript, the honey pot section of the form is removed from the DOM when the page loads, hiding it from your users. The argument for this method is most bots don't implement javascript, so the honey pot field will not be hidden from them. I think that is a valid argument but I didn't want to include extra javascript in my page--so I went with the CSS method.

                                                            \n

                                                            There are references at the end of the show notes to a couple of the articles I read on implementing the honey pot with either javascript or CSS. My take away was, one, don't use the CSS display property set to the value of none to take the input out of the DOM. Sufficiently smart enough bots may know to scan for this, especially if applied directly to the element. Also don't name your classes something obvious to your intent like \"anti-spam-filter\". My guess is the majority of the bots out there aren't that sophisticated, but I figured it couldn't hurt to follow those suggestions.

                                                            \n

                                                            I was already using Bootstrap CSS for our site, so I decided to use Bootstrap's \"sr-only\" class. This class is used for elements that you only want visible to screen readers. It takes the element and uses a combination of absolute positioning, setting the size and width to 1 pixel, setting a negative left margin, and hiding content overflow to prevent the honey pot showing up visually. I figured if the bot was scanning CSS for classes or properties, this wouldn't trigger any warnings. It does bring up the issue of how to prevent impacting the experience of people using screen readers. I applied the aria-hidden attribute with a value of true to the label element surrounding the honey pot input field. \"[this] removes that element and all of its children from the accessibility tree.\" So we now have the field hidden both visually in the browser and from assistive technologies. Given the short end of the stick accessibility usually gets, I doubt there are any spam bots scanning for that ARIA attribute. For the minority of users who might be viewing with the classic lynx browser, I put 'For office use' as the label text before the honey pot, hoping this would get the message across without tipping off the bot to the intended purpose of the related input field.

                                                            \n

                                                            The other main issue with this method is the value of the name attribute used for the input field. Some argue to use obfuscated values like \"mmxxName\" instead of \"name\", or \"sxysPhone\" for \"phone\". Apparently some bots will skip fields they don't recognize. By using more standard names for multiple honey pot fields, it easier to determine if it is a bot. The counter argument to this naming scheme is about the user experience, by obfuscating the name, then browsers won't auto-fill the valid fields of the form. This also brings up the matter of not auto-filling the spam fields by the browser of your users. This is done by setting any of your honey pot input elements' \"autocomplete\" attributes to \"off\".

                                                            \n

                                                            So far this spam filtering method is working nicely. I currently send any messages flagged as spam to a different email address with the subject prepended with the words \"[Spam review]\". Once I am confident there are not that many false positives, I will just skip sending flagged messages. The one issue I have experienced with this method is when using the tab key to move through the form. Since the input field is only visually hidden, it still receives focus as you tab through. If you happen to hit another key while still in the hidden field, it will get captured by the honey pot and then the submission will be flagged as spam.

                                                            \n

                                                            I have created a sample form on my personal site. Please visit URL: https://www.horning.us/hpr/SpamBotHoneyPot.php to try it out. It is a simple PHP page using the GET method when submitting the form. Once you press the submit button you will see the form fields and their values, along with the result messages. I chose to use \"URL\" as the name for my honey pot input field. I use it on my example form, and I use it for my work form. For my work form, a URL is not something we ask to be submitted, and being a common field in forms, makes it very tempting for bots. In my example code, the CSS for hiding the honey pot section is from the minicss.org websites. Their \"visibility-hidden\" class is very similar to Bootstrap's \"sr-only\" class. I would be interested to hear if others have implemented something similar. I would also love to hear from someone who uses a screen reader. Does it prevent the honey pot section from being read?

                                                            Introduction

                                                            \n

                                                            After many years of confusion it has been decided to produce a common standard for dates and times between Europe and the United States of America.

                                                            \n

                                                            When encountering a USA date such as 03/14/2021 (known as Pi Day in the USA) there has been ambiguity over which part of the date is the day and which the month. There can also be confusion as to the year if the two-digit form is used.

                                                            \n

                                                            Standardisation is a way in which these sorts of ambiguities can be resolved. Having a common method of representation avoids confusion.

                                                            \n

                                                            Therefore, starting in 2021, in the spirit of clarity and prevention of misunderstanding, the EU has decided to standardise on compatible formats wherever possible.

                                                            \n

                                                            Dates

                                                            \n

                                                            Henceforward dates will be represented in one of the following forms:

                                                            \n
                                                            MM/DD/YY    month/day of month/two-digit year\n\nYY/DD/MM    two-digit year/day of month/month
                                                            \n

                                                            Thus, 21/14/03 or 03/14/21 will be universally recognised as Pi Day.

                                                            The break from the previous tyranny of large|medium|small or small|medium|large formats has been extended to 24-hour time representations.

                                                            I did not get any feed back on my first nagios episode, so I can only assume that I perfectly explained what nagios is. And my installation instructions were so good, that no one had any questions. So I will move on to some additional nagios topics.

                                                            One thing I meant to talk about but forgot in the intro is why you may want to run nagios as a hobbyist.

                                                            Most of the benefits of nagios are not specific to nagios. There are plenty of other options for monitoring, and all of them are worth exploring.

                                                            I had planned on discussing how to set up postfix to send emails. But, that is such a big topic I will have to skip it. I will instead talk about what I do to send email. And Maybe you can do something similar.

                                                            \n

                                                            Spammers have ruined the ability to directly send email. Most residential ISPs block port 25 outbound to prevent malware from sending email. Some Virtual hosting providers may not block sending mail, but many mail servers will not accept mail from VPS IP ranges.

                                                            \n

                                                            There are a few ways to get around this problem. I use the email delivery service Sendgrid. They do all the work of staying off the list of spammers, and most email providers trust mail send via Sendgrid.

                                                            \n

                                                            I wont go into the instructions for configuring postfix to relay outgoing mail via Sendgrid, but their documentation is easy to follow.

                                                            \n

                                                            There are plenty of services like sendgrid. And most have a free tier. So unless you are blasting out alerts you probably will not have to pay. If you want to send alerts from nagios via email, I recommend finding a email sending service that works for you.

                                                            \n

                                                            There are a few options (besides email) for getting alerts on your phone.

                                                            \n

                                                            \n

                                                            The easiest way to get alerts is probably the aNag Android app. aNag connects to the nagios UI to get status updates. It can be configured to check in periodically and there generate notifications for failed checks.

                                                            \n

                                                            One downside to aNag is the phone has to be able to connect to the nagios server. So, if nagios is on a private network, you will need a VPN when you are not on the same network.

                                                            \n

                                                            If you decide to put nagios on a public network, be sure to configure apache to only use HTTPS. certbot makes this really easy.

                                                            \n

                                                            Pushover

                                                            \n

                                                            Another option is to us a Push Notification service that can send notifications that are triggered by API calls.

                                                            \n

                                                            I like to use the pushover.net You pay $5 when you download the pushover app from the app store, and then notifications are sent for free. They offer a 30 day trial if you want to evaluate the service.

                                                            \n

                                                            To use pushover, we will add a new contact to nagios. The command for the pushover contact is a script that calls the pushover API via curl.

                                                            \n

                                                            Remember from the previous episode, nagios has a conf.d directory and will load any files in that directory. So we will create a new file /etc/nagios4/conf.d/pushover.cfg and restart nagios. The contents of the pushover file will be in the show notes.

                                                            One of the big advantages of nagios is the ability to write custom checks. In the previous episode, I mentioned that the status of the nagios checks are based on exit code.

                                                            \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

                                                            So, to write a custom check, we need a script that will perform a check, and exit with an exit code based on the results of the check.

                                                            \n

                                                            I have a server where occasionally the syslog daemon stop running,

                                                            \n

                                                            Instead of trying to figure out why syslog keeps crashing, I wrote a script to check the log file is being updated. The script looks for the expected log file and tests that it has been modified in the last few minutes. The script will:

                                                            \n
                                                              \n
                                                            • exit 0 if the syslog file is less than 1 minute old
                                                              • \n
                                                            • exit 1 if the syslog file is less than 10 minutes old
                                                              • \n
                                                            • exit 2 if the syslog file is more that than 10 minutes old or does not exist
                                                              • \n
                                                            \n

                                                            Since the server with the crashy syslog is not the same server running nagios, I need a way for nagios to execute the script on the remote server.

                                                            \n

                                                            Nagios has a few ways to run check commands on remote servers. I prefer to use ssh, but there are some disadvantages to using ssh. Specifically the resources required to establish the ssh connection can be heavier than some of the other remote execution methods.

                                                            \n

                                                            The check_by_ssh plugin can be used to execute check commands on another system. Typically ssh-key authentication is set up so the user that is running the nagios daemon can log in to the remote system without a password

                                                            \n

                                                            You can try the command to make sure it is working.

                                                            \n
                                                            cd /usr/lib/nagios/plugins\n./check_by_ssh -H RemoteHost -u RemoteUser \\\n-C /path/to/remote/script/check_log_age.sh
                                                            \n

                                                            The new command can be added to a file in the nagios conf.d directory

                                                            \n
                                                            define command {\n    command_name check_syslog_age\n    command_line    $USER1$/check_by_ssh  -u RemoteUser -C /remote/path/check_log_age.sh\n        }
                                                            \n

                                                            After adding the command definition, check_syslog_age can be added as a service check.

                                                            \n

                                                            SNMP can get complicated and I have mixed feelings about using it. I am not going to go into the SNMP versions or the different authentication options for SNMP. But I will show a minimal setup that allows some performance data to be checked by nagios

                                                            \n

                                                            The SNMP authentication that I am demonstrating is only appropriate for isolated networks. If you plan to use snmp over a public network, I recommend looking into more secure versions of SNMP or tunnelling the check traffic via ssh or a VPN.

                                                            SNMP setup

                                                            \n

                                                            First we need to configure the client to respond to SNMP request. On Ubuntu, apt install snmpd

                                                            \n

                                                            By default, snmpd listens on localhost. Replace the existing snmpd.conf with this example to set a read only community string and listen on all IP addresses.

                                                            \n

                                                            And don't forget, I do not recommend this for a Public Network. Restart snmpd and open port 161 if there is a firewall enabled.

                                                            \n

                                                            SNMP nagios checks

                                                            \n

                                                            The nagios plugin package installs several pre-defined snmp checks in /etc/nagios-plugins/config/snmp.cfg Look through the file to get an idea of the checks that can be performed via SNMP.

                                                            \n

                                                            Below is an example of a client configuration that uses SNMP. If you look at how the command definitions, most of them have an option to accept arguments to modify how the check is done The argument placeholders re represented by $ARG1$

                                                            \n

                                                            In most cases, the arguments are optional. This particular SNMP check for disk space requires an argument to complete the disk ID being checked.

                                                            \n

                                                            When the service check is defined, the arguments are separated by ! You can also see in the example how you can

                                                            Nagios has plugins that can check if there are system updates required.

                                                            • Check will be CRITICAL if any of the updates are security related.

                                                            The check plugin is installed on the remote server. The plugin for Debian based systems is nagios-plugins-contrib or nagios-plugins-check-updates for Red Hat based systems.

                                                            \n

                                                            The command definitions are below. Since the plugins take longer to run, you will probably need to modify the nagios plugin timeout.

                                                            \n
                                                            define command {\n    command_name check_yum\n        command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -t 120 -u root -C "/usr/lib64/nagios/plugins/check_updates -t120"\n    }\ndefine command {\n       command_name check_apt\n       command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -t 120 -u nagios-ssh -C "/usr/lib/nagios/plugins/check_apt -t60"\n        }
                                                            \n

                                                            That's probably all the nagios I can handle for now. Leave a comment if there are nagios topics you would like to hear about. Thanks for listening and I will see you next time.

Folks have been emailing, phoning, texting, tagging me on social media (— the last of which has been funny, because all my social media accounts are placeholder accounts). But, just about everyone has urged me to comment on the serious issues that the software freedom community now faces. Until now, I have stayed silent regarding all these current topics: from Richard M. Stallman (RMS)’s public statements, to his resignation from the Free Software Foundation (FSF), to the Epstein scandal and its connection to MIT. I’ve also avoided generally commenting on software freedom organizational governance during this period. I did this for good reason, which is explained below. However, in this blog post, I now share my primary comments on the matters that seem to currently be of the utmost attention of the Open Source and Free Software communities.\n

                                                            \n

                                                            \nI have been silent the last month because, until two days ago, I was an at-large member of FSF’s Board of Directors, and a Voting Member of the FSF. As a member of FSF’s two leadership bodies, I was abiding by a reasonable request from the FSF management and my duty to the organization. Specifically, the FSF asked that all communication during the crisis come directly from FSF officers and not from at-large directors and/or Voting Members. Furthermore, the FSF management asked all Directors and Voting Members to remain silent on this entire matter — even on issues only tangentially related to the current situation, and even when speaking in our own capacity (e.g., on our own blogs like this one). The FSF is an important organization, and I take any request from the FSF seriously — so I abided fully with their request.\n

                                                            \n

                                                            \nThe situation was further complicated because folks at my employer, Software Freedom Conservancy (where I also serve on the Board of Directors) had strong opinions about this matter as well. Fortunately, the FSF and Conservancy both had already created clear protocols for what I should do if ever there was a disagreement or divergence of views between Conservancy and FSF. I therefore was recused fully from the planning, drafting, and timing of Conservancy’s statement on this matter. I thank my colleagues at the Conservancy for working so carefully to keep me entirely outside the loop on their statement and to diligently assure that it was straight-forward for me to manage any potential organizational disagreements. I also thank those at the FSF who outlined clear protocols (ahead of time, back in March 2019) in case a situation like this ever came up. I also know my colleagues at Conservancy care deeply, as I do, about the health and welfare of the FSF and its mission of fighting for universal software freedom for all. None of us want, nor have, any substantive disagreement over software freedom issues.\n

                                                            \n

                                                            \nI take very seriously my duty to the various organizations where I have (or have had) affiliations. More generally, I champion non-profit organizational transparency. Unfortunately, the current crisis left me in a quandary between the overarching goal of community transparency and abiding by FSF management’s directives. Now that I’ve left the FSF Board of Directors, FSF’s Voting Membership, and all my FSF volunteer roles (which ends my 22-year uninterrupted affiliation with the FSF), I can now comment on the substantive issues that face not just the FSF, but the Free Software community as a whole, while continuing to adhere to my past duty of acting in FSF’s best interest. In other words, my affiliation with the FSF has come to an end for many good and useful reasons. The end to this affiliation allows me to speak directly about the core issues at the heart of the community’s current crisis.\n

                                                            \n

                                                            \nFirstly, all these events — from RMS’ public comments on the MIT mailing list, to RMS’ resignation from the FSF to RMS’ discussions about the next steps for the GNU project — seem to many to have happened ridiculously quickly. But it wasn’t actually fast at all. In fact, these events were culmination of issues that were slowly growing in concern to many people, including me.\n

                                                            \n

                                                            \nFor the last two years, I had been a loud internal voice in the FSF leadership regarding RMS’ Free-Software-unrelated public statements; I felt strongly that it was in the best interest of the FSF to actively seek to limit such statements, and that it was my duty to FSF to speak out about this within the organization. Those who only learned of this story in the last month (understandably) believed Selam G.’s Medium post raised an entirely new issue. In fact, RMS’ views and statements posted on stallman.org about sexual morality escalated for the worse over the last few years. When the escalation started, I still considered RMS both a friend and colleague, and I attempted to argue with him at length to convince him that some of his positions were harmful to sexual assault survivors and those who are sex-trafficked, and to the people who devote their lives in service to such individuals. More importantly to the FSF, I attempted to persuade RMS that launching a controversial campaign on sexual behavior and morality was counter to his and FSF’s mission to advance software freedom, and told RMS that my duty as an FSF Director was to assure the best outcome for the FSF, which IMO didn’t include having a leader who made such statements. Not only is human sexual behavior not a topic on which RMS has adequate academic expertise, but also his positions appear to ignore significant research and widely available information on the subject. Many of his comments, while occasionally politically intriguing, lack empathy for people who experienced trauma.\n

                                                            \n

                                                            \nIMO, this is not and has never been a Free Speech issue. I do believe freedom of speech links directly to software freedom: indeed, I see the freedom to publish software under Free licenses as almost a corollary to the freedom of speech. However, we do not need to follow leadership from those whose views we fundamentally disagree. Moreover, organizations need not and should not elevate spokespeople and leaders who speak regularly on unrelated issues that organizations find do not advance their mission, and/or that alienate important constituents. I, like many other software freedom leaders, curtail my public comments on issues not related to FOSS. (Indeed, I would not even be commenting on this issue if it had not become a central issue of concern to the software freedom community.) Leaders have power, and they must exercise the power of their words with restraint, not with impunity.\n

                                                            \n

                                                            \nRMS has consistently argued that there was a campaign of \"prudish intimidation\" — seeking to keep him quiet about his views on sexuality. After years of conversing with RMS about how his non-software-freedom views were a distraction, an indulgence, and downright problematic, his general response was to make even more public comments of this nature. The issue is not about RMS’ right to say what he believes, nor is it even about whether or not you agree or disagree with RMS’ statements. The question is whether an organization should have a designated leader who is on a sustained, public campaign advocating about an unrelated issue that many consider controversial. It really doesn’t matter what your view about the controversial issue is; a leader who refuses to stop talking loudly about unrelated issues eventually creates an untenable distraction from the radical activism you’re actively trying to advance. The message of universal software freedom is a radical cause; it’s basically impossible for one individual to effectively push forward two unrelated controversial agendas at once. In short, the radical message of software freedom became overshadowed by RMS’ radical views about sexual morality.\n

                                                            \n

                                                            \nAnd here is where I say the thing that may infuriate many but it’s what I believe: I think RMS took a useful step by resigning some of his leadership roles at the FSF. I thank RMS for taking that step, and I wish the FSF Directors well in their efforts to assure that the FSF becomes a welcoming organization to all who care about universal software freedom. The FSF’s mission is essential to our technological future, and we should all support that mission. I care deeply about that mission myself and have worked and will continue to work in our community in the best interest of the mission.\n

                                                            \n

                                                            \nI’m admittedly struggling to find a way to work again with RMS, given his views on sexual morality and his behaviors stemming from those views. I explicitly do not agree with this \"(re-)definition\" of sexual assault. Furthermore, I believe uninformed statements about sexual assault are irresponsible and cause harm to victims. #MeToo is not a \"frenzy\"; it is a global movement by individuals who have been harmed seeking to hold both bad actors and society-at-large accountable for ignoring systemic wrongs. Nevertheless, I still am proud of the essay that I co-wrote with RMS and still find many of RMS’ other essays compelling, important, and relevant.\n

                                                            \n

                                                            \nI want the FSF to succeed in its mission and enter a new era of accomplishments. I’ve spent the last 22 years, without a break, dedicating substantial time, effort, care and loyalty to the various FSF roles that I’ve had: including employee, volunteer, at-large Director, and Voting Member. Even though my duties to the FSF are done, and my relationship with the FSF is no longer formal, I still think the FSF is a valuable institution worth helping and saving, specifically because the FSF was founded for a mission that I deeply support. And we should also realize that RMS — a human being (who is flawed like the rest of us) — invented that mission.\n

                                                            \n

                                                            \nAs culture change becomes more rapid, I hope we can find reasonable nuance and moderation on our complex analysis about people and their disparate views, while we also hold individuals fully accountable for their actions. That’s the difficulty we face in the post-post-modern culture of the early twenty-first century. Most importantly, I believe we must find a way to stand firm for software freedom while also making a safe environment for victims of sexual assault, sexual abuse, gaslighting, and other deplorable actions.\n

This might lead more women to get tested, and abort fetuses that have Down’s syndrome. Let’s hope so! If you’d like to love and care for a pet that doesn’t have normal human mental capacity, don’t create a handicapped human being to be your pet. Get a dog or a parrot. It will appreciate your love, and it will never feel bad for being less capable than normal humans.

This campaign seems to be sheer bull-headed prudery, using the perverse assumption that sex between a human and an animal hurts the animal. That’s true for some ways of having sex, and false for others. For instance, I’ve heard that some women get dogs to lick them off. That doesn’t hurt the dog at all. Why should it be prohibited? When male dolphins have sex with people, that doesn’t hurt the dolphins. Quite the contrary, they like it very much. Why should it be prohibited? I’ve also read that female gorillas sometimes express desire for sex with men. If they both like it, who is harmed? Why should this be prohibited? The proponents of this law claim that any kind of sex between humans and other species implies that the human is a \"predator\" that we need to lock up. That’s clearly false, for the cases listed above. Making a prohibition based on prejudice, writing it in an overbroad way, is what prissy governments tend to do where sex is concerned. The next step is to interpret it too strongly with \"zero tolerance\". Will people convicted of having dogs lick them off be required to live at least 1000 feet from any dogs? This law should be changed to prohibit only acts in which the animal is physically forced to have sex, or physically injured.

Why do people think there is something wrong with a sexual relationship between people of ages 13 and 18? The principal activity of human adolescents is sex.

Her husband acted as a lookout in case someone else passed by. One teenager allegedly visited her at her house repeatedly to have sex with her. None of these acts would be wrong in any sense, provided they took precautions against spreading infections. The idea that adolescents (of whatever sex) need to be \"protected\" from sexual experience they wish to have is prudish ignorantism, and making that experience a crime is perverse.

(We are talking about sex practices that don’t physically hurt the animal.) These laws have no rational basis. We know that some animals enjoy sex with humans. Others don’t. But really, if you smear something on your genitals that tastes good to dogs, and have a dog lick you off, it harms no one. Why should this be illegal except mindless religion?

He tried to lead Ms Corfman step by step into sex, but he always respected \"no\" from her and his other dates. Thus, Moore does not deserve the exaggerated condemnation that he is receiving for this. As an example of exaggeration: one mailing referred to these teenagers as \"children\", even the one that was 18 years old. Many teenagers are minors, but none of them are children. The condemnation is surely sparked by the political motive of wanting to defeat Moore in the coming election, but it draws fuel from ageism and the fashion for overprotectiveness of \"children\". I completely agree with the wish to defeat Moore. Political Christianists such as Moore hold views that conflict essentially with human rights, just as political Islamists do. If Moore, with his extremist policies, gains public office again, he will harm millions of American women, and secondarily society as a whole. Ms Corfman says she was hurt afterward, and attributes this to feelings of guilt based on the belief that she had done something wrong (which, of course, she had not). Is this is another sign of Christianity at work? I sent a check to Doug Jones US Senate a few weeks ago. Please support his campaign too.

As far as I can tell from this article, he didn’t try to force women into sex. When women persistently said no, he does not seem to have tried to punish them. The most he did was ask. He was a pest, but nothing worse than that.

They were teenagers. What about \"rape\"? Was this really rape? Or did they have sex willingly, and prudes want to call it \"rape\" to make it sound like an injustice? We can’t tell from the article which one it is. Rape means coercing someone to have sex. Precisely because that is a grave and clear wrong, using the same name for something much less grave is a distortion.

We can hardly assume that the bullshitter’s boasts were true. Even men who are usually honest on other topics have been known to lie about their sexual achievements. However, I wouldn’t assume they were false, or that he did an injustice to anyone at these parties. In a group of 50 models, there could well be some that would eagerly go to bed with a rich man, either to boost their careers or for a lark. If you condemn men for finding teenage female models attractive, you might as well condemn men for being heterosexual. The bully may be predatory, but it appears he didn’t display this overtly at those parties. There are indications that he arbitrarily chose the winners of the Miss USA beauty contest while he owned it. That would be a real wrong, since it would have made the contest dishonest. I understand the desire to condemn the bullshitter on every aspect of his life, but it is no excuse for ageism. If you can understand that we shouldn’t dictate people’s gender preferences, you should understand that we shouldn’t dictate their age preferences either. There are plenty of tremendously important reasons to condemn the bully. He is attacking workers’ rights, abortion rights, non-rich people’s pensions and medical care, the environment, human rights, and democracy, even the idea of truth. Let’s focus on those real reasons.

This accords with the view that Stendhal reported in France in the 1800s, that a woman’s most beautiful years were from 16 to 20. Although this attitude on men’s part is normal, the author still wants to present it as wrong or perverted, and implicitly demands men somehow control their attraction to direct it elsewhere. Which is as absurd, and as potentially oppressive, as claiming that homosexuals should control their attraction and direct it towards to the other sex. Will men be pressured to undergo \"age conversion therapy\" intended to brainwash them to feel attracted mainly to women of their own age?

The term includes rape, groping, sexual harassment, and other acts. These acts are not merely different in degree. They are different in kind. Rape is a grave crime. Being groped is unpleasant but not as grave as robbery. Sexual harassment is a not an action at all, but rather a pattern of actions that constitutes economic unfairness. How can it make sense to group these behaviors things together? It never makes sense. News articles, studies, and laws should avoid that term.

Her age has not been announced, but I think she must surely be a teenager, not a child. Calling teenagers \"children\" in this context is a way of smearing people with normal sexual proclivities as \"perverts\". They have accused him of \"sexual assault\", a term so vague that it should never be used at all. With no details, we can’t tell whether the alleged actions deserve that term. What we do know is that the term is often used for a legal lie. She may have had — I expect, did have — entirely willing sex with him, and they would still call it \"assault\".

Their sexual miseducation starts in adolescence, but many never learn better. Our society’s taboo cuts adolescents off from any way to learn about sexual relationships and lovemaking other than from porn and from other confused adolescents. Everyone learns the hard way, often slowly, and in many cases learns bad lessons. The more effective the taboo, the deeper the ignorance. In 18th century France, teenage girls of good family emerged totally sexually innocent from education in a convent. Totally innocent and totally exploitable (see Dangerous Liaisons). Contrast this with Marquesan society, where adolescents are not kept ignorant by a taboo on sex. They have various relationships with lovers of their choice, so they have many opportunities to see what pleases and what doesn’t. Any one lover can please them more, or please them less, but can’t mislead them — they have standards for comparison. In that society, even adolescents understand lovemaking better than a lot of American adults. Inevitably, everyone starts out ignorant; the question is, how can society offer people a path which leads them to learn to do things well, rather than learning painfully to do them badly.

You might as well demand that a homosexual be attracted to people not of the same sex. Or that a heterosexual be attracted to people that are of the same sex. There is no arguing about tastes. If we respect people’s right to say no, we should not rebuke them when they do. Of course, many people (especially men, but not only) despise those they find unattractive. That is a mean way to treat people who haven’t done anything wrong. But being unattracted by someone is not the same as despising per. Yann Moix understands this.

It might be due to the general stress and anxiety of life in the advanced countries. I suspect it is also due to the lack of any generally accepted way for men to express romantic or sexual interest in women. By \"generally accepted\", I mean that he can count on a woman who declines his interest not to revile him for expressing it that way.

Some senators that pushed him to resign now regret that too. The first (main) article does not state clearly whether Franken touched Tweeden in the process of making the photo, but it seems he did not. If that is correct, it was not a sexual act at all. It was self-mocking humor. The photograph depicted a fictional sexual act without her fictional consent, but making the photo wasn’t a sexual act. If it is true that he persistently pressured her to kiss him, on stage and off, if he stuck his tongue into her mouth despite her objections, that could well be sexual harassment. He should have accepted no for an answer the first time she said it. However, calling a kiss \"sexual assault\" is an exaggeration, an attempt to equate it to much graver acts, that are crimes. The term \"sexual assault\" encourages that injustice, and I believe it has been popularized specifically with that intention. That is why I reject that term. Meanwhile, Franken says he did not do those things, and the other actors he previously did the same USO skit with said it was not harassment, just acting. Tweeden’s store is clearly false in many details. Should we assume Tweeden was honest? With so many demonstrated falsehoods in her accusations, and given that she planned them with other right-wing activists, and that all of them follow a leader who lies as a tactic every day, I have to suspect that she decided to falsify accusations through exaggeration so as to kick a strong Democrat out of the Senate. I have no proof of that suspicion. It is possible that she made the accusations honestly. Also, in a hypothetical world, someone might really have done them. Supposing for the moment that those accusations were true, should Franken have resigned over them? I don’t think so. They are misjudgments, not crimes. Franken deserved the chance to learn from the criticism that surprised him. Zero tolerance is a very bad way to judge people. However, the most important point is to reject the position that if B feels hurt by what A said or did, then automatically A is wrong. People judged Franken that way, and he judged himself that way. But that way degrades the concept of \"wrong\" into a mere expression of subjective disapproval. What can legitimately be asserted subjectively can legitimately be ignored subjectively too. To judge A that way is to set B up as a tyrant. If B’s feelings were hurt, that’s unfortunate – but is that A’s fault? If so, was it culpable, or just a mistake? That is what we have to judge, and if we want others to think our judgments worth following, they must be based on objective facts and objective standards, including objective standards for what words and gestures objectively mean. Traister is wrestling with a solvable problem. She says, \"When you change rules, you end up penalizing people who were caught behaving according to the old rules.\" Maybe people do, but that is a sign of carelessness. It isn’t really hard to change the rules and then judge old actions by the old rules. We just have to remember to do so.

                                                            This episode is simply an introduction with a little bit of information about me

                                                            \n

                                                            My love of computers began 40 years ago when my parents scrimped and saved to purchase a Texas Instruments TI-99/4a computer. I began programming in BASIC, saving programs to audio cassette tapes. I remember buying magazines to get new programs to enter, save, edit, and turn into something different.

                                                            \n

                                                            Soon I expanded the computer to include 32K of RAM and an RS232 card which allowed me to connect a 300 BAUD modem and connect to bulletin board systems (BBS). BBS became my connection to the world.

                                                            \n

                                                            I later upgraded to a Commodore 64, which gave me a floppy disk. Much faster than saving to tape. I studied electronics & computers in college, then went to work for a large computer vendor, traveling all over fixing computers, networks, and peripherals.

                                                            \n

                                                            After about a decade, I joined a different company where I worked in systems administration and engineering, with a focus on information security. I have worked as security analyst, incident responder, security engineer, and security architect, then built out and managed the SOC for a large organization.

                                                            \n

                                                            Today, I am still focused on information security and I also dabble in clock repair, Ham radio, electronics, and photography. I may record some episodes on some of these topics in the future.

Stallman remained head of the GNU Project nevertheless and, in 2021, he returned to the FSF board of directors.

                                                            \nThe voting members of the Free Software Foundation, which include the board of directors, voted to appoint Richard Stallman to a board seat after several months of thorough discussion and thoughtful deliberation.\n

                                                            \n

                                                            \nWe decided to bring RMS back because we missed his wisdom. His historical, legal and technical acumen on free software is unrivaled. He has a deep sensitivity to the ways that technologies can contribute to both the enhancement and the diminution of basic human rights. His global network of connections is invaluable. He remains the most articulate philosopher and an unquestionably dedicated advocate of freedom in computing.\n

                                                            \n

                                                            \nRMS acknowledges that he has made mistakes. He has sincere regrets, especially at how anger toward him personally has negatively impacted the reputation and mission of FSF. While his personal style remains troubling for some, a majority of the board feel his behavior has moderated and believe that his thinking strengthens the work of the FSF in pursuit of its mission.\n

                                                            \nWe take full responsibility for how badly we handled the news of his election to a board seat. We had planned a flow of information that was not executed in a timely manner or delivered in the proper sequence.\n

                                                            \n

                                                            \nFSF staff should have been informed and consulted first. The announcement by RMS at LibrePlanet was a complete surprise to staff, all those who worked so hard to organize a great event, to LibrePlanet speakers and to the exhibitors. We had hoped for a more inclusive and thoughtful process and we apologize that this did not occur.\n

                                                            \n

                                                            \nIn his position on the board, RMS has the same responsibilities as other members. He is an unpaid volunteer and subject to the organization’s policies, including prohibitions against conflicts of interest and sexual harassment and those outlining whistleblower processes and fiduciary duties. The responsibilities of the board are described at https://www.fsf.org/about/the-role-of-the-fsfs-board-of-directors.\n

                                                            \nWe believe his views will be critical to the FSF as we advance the mission and confront the challenges that software freedom faces.\n

                                                            \nIn recent weeks, the board has committed to a series of changes related to organizational governance, including plans to adopt a transparent, formal process for identifying appropriate candidates to become new board members, future changes to the organization’s bylaws, and the addition of a staff representative to the board of directors.\n

We recognize the need to attract a new generation of activists for software freedom and to grow the movement. We will report our discussions and activities to the community as we move forward.\n

                                                            \nEver since my teenage years, I felt as if there were a filmy curtain separating me from other people my age. I understood the words of their conversations, but I could not grasp why they said what they did. Much later I realized that I didn’t understand the subtle cues that other people were responding to.\n

                                                            \n

                                                            \nLater in life, I discovered that some people had negative reactions to my behavior, which I did not even know about. Tending to be direct and honest with my thoughts, I sometimes made others uncomfortable or even offended them – especially women. This was not a choice: I didn’t understand the problem enough to know which choices there were.\n

                                                            \n

                                                            \nSometimes I lost my temper because I didn’t have the social skills to avoid it. Some people could cope with this; others were hurt. I apologize to each of them. Please direct your criticism at me, not at the Free Software Foundation.\n

                                                            \n

                                                            \nOccasionally I learned something about relationships and social skills, so over the years I’ve found ways to get better at these situations. When people help me understand an aspect of what went wrong, and that shows me a way of treating people better, I teach myself to recognize when I should act that way. I keep making this effort, and over time, I improve.\n

                                                            \n

                                                            \nSome have described me as being “tone-deaf,” and that is fair. With my difficulty in understanding social cues, that tends to happen. For instance, I defended Professor Minsky on an M.I.T. mailing list after someone leaped to the conclusion that he was just guilty as Jeffrey Epstein. To my surprise, some thought my message defended Epstein. As I had stated previously, Epstein is a serial rapist, and rapists should be punished. I wish for his victims and those harmed by him to receive justice.\n

                                                            \n

                                                            \nFalse accusations – real or imaginary, against me or against others – especially anger me. I knew Minsky only distantly, but seeing him unjustly accused made me spring to his defense. I would have done it for anyone. Police brutality makes me angry, but when the cops lie about their victims afterwards, that false accusation is the ultimate outrage for me. I condemn racism and sexism, including their systemic forms, so when people say I don’t, that hurts too.\n

                                                            \n

                                                            \nIt was right for me to talk about the injustice to Minsky, but it was tone-deaf that I didn’t acknowledge as context the injustice that Epstein did to women or the pain that caused.\n

                                                            \n

                                                            \nI’ve learned something from this about how to be kind to people who have been hurt. In the future, that will help me be kind to people in other situations, which is what I hope to do.\n

                                                            \nUnion staff selected senior systems administrator Ian Kelling to be the first in this role. At the end of today’s board meeting, we officially welcomed Ian to both bodies. The board and voting members look forward to having the participation of the staff via this designated seat in our future deliberations. This is an important step in the FSF’s effort to recognize and support new leadership, to connect that leadership to the community, to improve transparency and accountability, and to build trust. There is still considerable work to be done, and that work will continue.\n

                                                            \nI have always known that the FSF has good and hard-working staff, but with the success of LibrePlanet 2021, and in talking with staff during the controversy that unfolded immediately afterward, I have no doubt it is essential to involve staff much more in decision-making and strategy discussions. The advice they have offered in the last week alone has been invaluable. I sincerely believe this step in improving FSF governance will lead to better outcomes going forward. In all my interactions with Ian so far, he has demonstrated abundant wisdom and intelligence.\n

                                                            Three good decades ago, Richard Stallman founded the free software movement and gave it a name.

                                                            \n

                                                            Two good decades ago there was a fork and Eric S. Raymond, Bruce Perens and others founded the open\nsource software movement, and neglected to tell us who gave it a name.\n(it was Christine Peterson[0])

                                                            \n

                                                            Ever since then, the free software side of the two movements has been careful to guard the boundary\nbetween the two, see Richard Stallman's essay \"Open Source Misses the Point\".[1]

                                                            \n

                                                            But lately a lot of people have increasingly been feeling that free software misses the point.\nIronically a lot of this has been coming from the open source side of things, as the official free\nsoftware philosophy has been firmly anchored with Stallman, and he hasn't been interested in moving\nhis philosophy in more inclusive directions.

                                                            \n

                                                            For sure, there are a lot of people in free software who have been wanting to go in this direction\nas well. I've been thinking of it as a \"free software plus\", as it builds on the free software\nphilosophy, but adds aspects of social responsibility. The fact that Stallman was forced to resign\nfrom being Free Software Foundation president two years ago was a sign that people inside free\nsoftware cared about more than just the code and what freedoms it gives the recipient.

                                                            \n

                                                            A month ago, if you are listening to this on April the 20th 2021,\na manifesto was published called \"Towards A Communal Software Movement\", and I'll get to\nthat in a minute. I mentioned the names of the drivers of the previous movements, but this author\nhas said \"I intentionally left authors' names out of it\"[2], and I think that makes sense. Part of the\nproblems with previous movements has been this Great Man of History fallacy, which may have kept\nthem focused and on track, but it has also held them back.

                                                            \n

                                                            The movement is young and has already changed names once as I was writing about it. The manifesto is\nnow \"Towards A Cooperative Technology Movement\", and I have updated the shownotes and my commentary\nto reflect that.

                                                            \n

                                                            https://misskey.de/notes/8k0igd5tcd

                                                            \n

                                                            I see the difference between free software and cooperative technology similarly as the difference\nbetween open source and free software.

                                                            \n

                                                            There are certainly people within open source and on the Open Source Initiative board that look\nfurther than just the license, and treat open source like just another brand name for free software.

                                                            \n

                                                            But at its core, the Open Source Definition is all about the licensing and that document is the\nshared common ground for all open source. People write code for different reasons and there's a\nlicense and contribution model that allow them to come together without those differences of purpose\ngetting too much in the way.

                                                            \n

                                                            So if the software and the license is \"what\" we're building, the philosophical documents of free\nsoftware provide the guidance on \"why\" we are building it: We want to get away from proprietary\nsoftware, we want to control our own computing, we want the freedoms to use, learn, modify and\nshare, etc. Free software is about our freedoms.

                                                            \n

                                                            So just like \"free\" is right there in the name, maybe the \"community\" in \"communal software\" or\nthe \"cooperative\" in \"cooperative technology\" is\nall about the \"who\": Who gets the freedom, who has the influence, who is affected.

                                                            \n

                                                            And again, lots of people in free software do care about community principles beyond code, care about\nsocial responsibility, but the shared baseline is the care for formal, technical and individual user\nfreedom: If you receive the code, you are allowed the technical rights to update the code, the\ncode or license should not restrict your freedoms, you, the recipient of the software, the hacker,\nthe code contributor. It says nothing about practical user freedom and it says nothing about the\ncommunity beyond the immediate user.

                                                            \n

                                                            That was my commentary. Now let's read the manifesto.

                                                            In response to the surprise, undemocratic reinstatement of Richard Stallman to the board of directors of the Free Software Foundation after his resignation in September 2019, the Free and Open Source Software movement is in the midst of a reckoning.\nThe authors of this document recognize and honor the contributions Richard Stallman has made to this movement while unequivocally condemning his harmful behavior which has pushed many capable, dedicated people away from the movement.

                                                            \n

                                                            Regardless of what happens in the Free Software Foundation, we believe it is time to reflect on the shortcomings of our advocacy so we can grow into a more effective and inclusive movement for justice.\nTowards this end, we believe the movement will benefit from new terminology to describe what we do and what we aim for.\nRichard Stallman authored the free software definition in 1986.\nThis term has always created difficulties communicating the ideas behind it because of the different meanings of the word \"free\" in English.\nMoreover, it is not the freedom of machines we are concerned with, but the freedom of humans.\nIn response to this and other issues, in 1998, the term open source was promoted using an adapted version of the Debian Free Software Guidelines.\nThe history of computing in the past 23 years have validated critiques that the term \"open source\" is insufficient for communicating the values behind it.\nThe term \"open source\" and the ecosystem of Free and Open Source Software (FOSS) is today used by powerful companies, governments, and other institutions to harm people on enormous scales through surveillance and violence.\nThese institutions use FOSS to minimize economic costs by benefitting from decades of work done by others, much of which was done by unpaid volunteers motivated by curiosity, passion, and the ideals of the FOSS movement.

                                                            \n

                                                            We believe a significant reason for the failures of both \"free software\" and \"open source\" to prevent this cooptation is that the men who coined and initially promoted these terms did not and do not critique capitalism.\nRichard Stallman has generally dodged the question of whether free software is opposed to capitalism.\nIn the historical context of the United States in the 1980s, that may have been a wise decision.\nBut that was then, and now it is 2021.\nThe promoters of \"open source\" emphasize its compatibility with capitalism and go out of their way to distance \"open source\" from critiques of capitalism.\nWe believe we need to build on the FOSS movement with an explicitly anticapitalist political movement which proactively collaborates with other movements for justice.

                                                            \n

                                                            We propose the term \"cooperative technology\" for this movement.\nBy \"cooperative technology\", we mean technology that is constructed by and for the people whose lives are affected by its use.\nWhile this builds on the Free and Open Source Software movement, we aim to apply the same principles to hardware as well, although the criteria by which we evaluate hardware and software will of course not be identical.\nIt is not sufficient to narrowly focus on the people who directly interact with computers.\nCooperative software which is run on a server should not be controlled solely by the administrator of the server, but also by the people who interact with the server over a network.\nSimilarly, the data generated by the technology and the data which it requires to function should be in the control of the people who are affected by the technology.\nCooperative software that uses cameras should not be controlled solely by the people who own the cameras, but also the people who are observed by the cameras.\nCooperative electronic medical record systems should not be designed for the interests of insurance companies or hospital administrators, but for the interests of patients and the clinicians who directly use it.

                                                            \n

                                                            We aim for a world in which all technology is cooperative technology and recognize that any amount of proprietary technology is in conflict with this goal.\nAs an anticapitalist movement, we recognize that any institution which motivates people to put money, power, or self-interest above the welfare of humans is in conflict with our goals.\nCorporations are beholden to their shareholders who can hold the corporation legally liable for spending money in a way that is not intended to further enrich the shareholders.\nOther capitalist forms of enterprise have similar problems, incentivizing the profit of an elite few over the impact their activities have on others.

                                                            \n

                                                            We are not opposed to exchanges of money being involved in the creation or distribution of software or hardware.\nHowever, we should carefully consider the motivational structures of the institutions which fund technology development.\nWho benefits from the technology and who determines the priorities of its development and design?\nThese are questions we ask about technology whether money is involved or not.\nIt is in our interest to use safeguards to ensure that technology always remains controlled by the community which develops and uses it.\nCopyleft is one such safeguard, but it is insufficient on its own to prevent cooptation of our movement.\nAny cooperative technology project that receives funding from a for-profit enterprise must institute governance structures which prioritize community interests over profit in case there is a conflict between the two.\nWe oppose business models which are in conflict with community interests such as \"open core\"/proprietary relicensing.

                                                            \n

                                                            Similarly, we are opposed to authoritarian and hierarchical governance structures of technology projects such as \"benevolent dictators for life\".\nCooperative technology is developed democratically; no single individual should have ultimate authority in cooperative projects.\nWhile we recognize the need for leadership and private communication, discussions regarding cooperative technology should take place in public unless there is a specific reason for communications to be private.\nOrganizations which advocate for cooperative technology should likewise operate democratically and transparently.

                                                            \n

                                                            We recognize that creating high quality technology requires much more than engineering skills.\nCooperative technology is not only for people who have the skills of writing code (unless the software is for writing code such as a compiler) nor the skills to design hardware.\nCooperative technology strives to be easy to use, including for people with disabilities, and acknowledges that this is best accomplished by continual dialog between engineers and users.\nProviding such feedback is a valuable way to contribute to the construction of cooperative technology without needing engineering skills.\nIdeally, the engineers of the technology should also be using it themselves.\nMoreover, there are many ways to contribute to cooperative technology without programming skills such as imagining ideas for new features, reporting bugs, writing documentation, graphic design, translation, promotion, and financial support.

                                                            \n

                                                            The free software movement has failed to create a world in which humans in technological societies can live without using proprietary software unless one chooses to live the ascetic lifestyle of Richard Stallman.\nExpecting people to not use any proprietary technology and judging people for not meeting this standard pushes people away from our movement.\nPeople who are coerced into using proprietary technology deserve our empathy and invitation into our movement, not condescension.\nLet us criticize institutions which pressure people into using proprietary technology, not the people who choose to use it.\nTo that end, we strive to use cooperative technology tools as much as possible in our efforts to build cooperative technology.

                                                            The purpose of this document is not to proclaim a legalistic set of criteria for determining what technology is cooperative and what technology is not.\nHistory has demonstrated that this is not an effective political tactic for the reasons explained above.\nThe free software definition and the open source definition are useful criteria for evaluating copyright licenses for code, but an effective political movement cannot be so narrowly focused on legalistic and binary judgements of copyright licenses to judge whether certain technology aligns with our goals.\nWe believe the focus of the cooperative technology movement should be on the practical impacts that the use of technology has on humans and the universe we inhabit.\nThe scope of this extends beyond humans and must consider the environment around us.\nMoreover, we believe it is counterproductive to have a small self-appointed group of privileged men determine what our movement's terminology, goals, and tactics are.\nWe encourage anyone interested in building a better world through technology to engage in discussions with your own communities about what you want \"cooperative technology\" to mean.

                                                            \n

                                                            While we agree with the Ethical Software Movement that we must resist when our efforts are coopted for unjust purposes, we reject putting restrictions on the ways people may use software through copyright licenses as a wise tactic for achieving our goals.\nThe history of the Free and Open Source Software movement has shown that the proliferation of incompatible copyright licenses which prohibit software from being legally combined creates more obstacles than opportunities for our movement.\nAny new copyright licenses for use with cooperative software must be written with this consideration in mind to intentionally avoid fracturing the software ecosystem.\nAdopting incompatible copyright licenses for different software would make it easy for our adversaries to divide and suppress the movement.

                                                            \n

                                                            Language is constructed collectively and is always evolving.\nIt is counterproductive to our movement to refuse to collaborate with people because they use the words \"open source\" or \"free software\" to describe their work.\nThey may even disagree with the entire premise of this document.\nThat does not mean we should not work together towards shared goals, but we should be conscious that our goals may not perfectly align and this may cause tension in our communities from time to time.\nWe invite anyone to collaborate with us who is interested in building a better world and treats us and others in our communities with dignity and respect.

                                                            \n

                                                            The project to upload the older HPR shows to archive.org has been quiescent for a few years. The shows between 1 and 870 had not been uploaded prior to April 2021 (though some shows had been uploaded in batches in the early days, without notes etc).

                                                            \n

                                                            However, this old show project has been restarted this month, after new software had been written to help manage the process. At the time of writing 65 shows in the range 1-870 have been uploaded, with notes, and with the same range of audio formats used for current shows.

                                                            \n

                                                            Since we don't want to upload shows without summaries or tags the two projects are now tied together. So we will be all the more welcoming of tag and summary updates sent to the address referenced in the next section!

                                                            \n

                                                            The plan is to report the numbers uploaded each month in the AOB section of the Community News show notes.

                                                            HPR shows on archive.org have the URL https://archive.org/details/hprXXXX where XXXX is the show number with leading zeroes. So for example, show 840's URL is: https://archive.org/details/hpr0840.

                                                            At the core of our philosophy is the notion that PINE64 is a community platform. A simplistic point of view, often offered up and referenced online, is that ‘PINE64 does hardware while the community does the software’. While this depiction is not inaccurate, it is also a gross oversimplification. The fact that PINE64 is community driven doesn’t simply entail a one-way reliance on the community or partner projects for software support; it means that the community gets to actively shape the devices, as well as the social platform, of PINE64 from the ground up. The goal is to deliver ARM64 devices that you really wish to engage with and a platform that you want to be a part of. As such, the community – PINE64 – and the company PINE Microsystems Inc. are interlocked and intertwined, but separate entities.

                                                            \n

                                                            What does it mean in practice then? It means that we usually announce what we’re working on well ahead of the shipping date – many months before a device is released – so that you have plenty of time to request product features, suggest changes, ask for/make changes to documentation, etc. before the first iteration of the device rolls of the factory line. It also means that the hardware developments – successes and failures alike – are all in the open. You can follow the process on our forum, the IRC, Discord, Matrix, Telegram the online conversations log and, in some instances, on our partner projects forums. But it also means that anyone who is a part of the community gets to shape anything related to the PINE64 project – including the Wiki or this website – and so, software development is only one area where you can contribute your time and skill. In return for time investment, the community gets fair priced devices that developers wish to spend their time on.

                                                            \n

                                                            Last, but not least, is our belief in supporting existing SoCs for long periods of time as well as actively developing new devices based on those SOCs. What does this mean for developers then? It means that a developer can start developing software on a PINE64 SBC and, in time, support multiple devices with relative ease. This device convergence is, at the time of writing, most pronounced on the Allwinner A64 SOC used in a number of our devices including the: PINE64-LTS, SOPine, Pinebook and Pinetab. That said, similar convergence is also planned for the Rockchip RK3399, currently used on the RockPro64 and in the Pinebook Pro.

                                                            You can always find us in the chats or the forum, so if you have any further questions make sure to drop by and ask about how the PINE64 project actually works.

                                                            Hello, again. My name is Trey. This is part 2 of a 6 part series related to information security podcasts.

                                                            \n

                                                            To recap Why am I recording this series?

                                                            \n

                                                            \"What podcasts you listen to\" was on the list of recommended topics

                                                            \n

                                                            I am passionate about information security

                                                            \n

                                                            We desperately need people to fill infosec jobs in many different specialties

                                                            \n

                                                            Infosec is a rapidly changing field, and it is critical to stay current

                                                            \n

                                                            As a result I listen to TONS of infosec related podcasts

                                                            \n

                                                            Because there are so many podcasts to list, I have broken them down into 6 different episodes based on topics:

                                                            I found this piece really fascinating and I like that you can take a huge problem and still consider it simple. It puts a lot of other problems into perspective and I like how this piece is written.

No expenses will be spared to bring to the listeners the finer details of tensors, TensorFlow and other frameworks which serve as the basis for modern artificial intelligence / machine learning applications running on back-propagation networks (see the first episode on the foundations). Lifting the curtain even more, all will be revealed about a little corner shop called \"Google\" (well, almost all :-).\n

                                                            Since we don't want to upload shows without summaries or tags the old shows and tag and summary projects are now tied together. So we will be all the more welcoming of tag and summary updates submitted as described on the summary page.

                                                            \nIn this episode, I revisit my spam bot honey pot method of spam detection for \nweb forms. The first part of the episode is a response to rtsn comment asking \nfor a follow up on how the method worked out. In the second part of the podcast \nI use the built-in screen reader of my Pop_OS system to review my test form and \nmy work form for audible accessibility and to check that the spam catching URL \nfield is not reveled by a screen reader. \n

Of those 134, 38 messages were uncaught spam--while the \nremaining 96 messages were valid inquiries. Overall, it seems to be doing a \ngood job. At one point, I thought about closing down the form, but the data \ndoes show we are receiving enough valid messages to make it worth keeping around \nand this method makes finding the good messages much easier.\n

It also reveals that making a form audibly accessible \ndoes take some care, and should be reviewed with a screen reader. My method \nfor hiding the honey pot URL field from the screen reader was effective, but my \noverall implementation to make it accessible needs more work.\n

I drink maybe four or five cups a day, depending on how early I get into work. I do try to have all this coffee in the morning, and am pretty good at not having any after lunch.

                                                            Now, I do need to recognise where I am, Australia, overall we've had a pretty good response to covid, fatalities have been very low by world standards. Having said that, I live in the part of Australia that has had the largest number and by far, longest lockdowns. Our longest one was 112 days.

                                                            \n

                                                            I've also travelled back home, and got caught in a lockdown in my home state of Queensland over Christmas.

                                                            \n

                                                            Eventually, the lockdowns ended, we were allowed go back to work, and I started using my home coffee machine less and less, and I lost motivation to do this show.

                                                            \n

                                                            Then, of course, we had another inevitable hotel quarantine leak, and that spread to Victoria, we're now looking at a breakout of around sixty cases and Victoria is back on lockdown so this is my fifth lockdown, and I'm back to working from home, and once again, I'm appreciating my new coffee pot, and once again I have motivation to do a story on it.

                                                            \n

                                                            What I really want to do is to disentangle the two topics, this episode will deal with all the covid stuff, the second episode will only deal with coffee.

                                                            \n

                                                            So this covid rant ends here, and now I need to start writing the script for the second part of the show, before lockdown ends..

                                                            Andrew and Dave describe a common itch they have been scratching. Andrew talks through his approach to document creation in this episode and Dave will describe his in the next episode.

                                                            \n

                                                            Andrew was inspired by a simple and elegant approach to eBook creation by Jon Kulp, possibly from listening to HPR 1909 several years ago.

                                                            \n

                                                            In Andrew's approach, bash and python scripts assemble various text files into the book, inserting figures and tables using a simple home-brew tag system to generate reference numbers such as Figure 3.7 or Table 2.2. Such auto-numbering functionality is of course provided by many other document authoring systems, such as LaTeX, but the script also uses the tags to hunt down data in CSV files and convert them into the figures. In this way, nearly all information in the book can start off as text and then be processed into anything — prose, graphics, sound or even movies — that can be included with HTML. Also a clean separation between content and appearance is kept by using a CSS file.

                                                            \n

                                                            This is not WYSIWYG (what you see is what you get) but using the entr command to monitor file changes can allow auto-generation of the HTML and even a browser refresh (using a feature found in Midori and Falkon but not many other browsers).

                                                            \n

                                                            Dave describes how he achieves something similar to what Andrew has created by using make to co-ordinate the processing. The process of compiling the source text files into a final document does have some similarities with code compilation.

                                                            \n

                                                            Dave and Andrew discuss how useful their methods might be to others. Some of Andrew's scripts are too bespoke to his use for wider consumption but the figure processing code is available online as part of the content and code of his book How Scotland Works.

                                                            \n

                                                            Andrew describes the horror of the suggestion that a non-fiction book does not need an index which prompted him to create his simple code to generate an index from a PDF. This was also motivated by laziness and a reluctance to read his own writing for the umpteenth time. Andrew then describes how this code works. The code itself can be found here.

                                                            \n

                                                            Dave brings up the issue of other formats such as epub which have no concept of pages, or at least do not insist on it natively.

                                                            \n

                                                            The discussion moves on to other tools for document and text processing that are relevant to the tasks involved such as pandoc, LaTex and ASCIIdoc. In particular, Dave mentions that the \"look\" of LaTeX is simpler to control these days, at least as compared to the 1990s!

In a previous life, I developed and ran the security awareness program for a large organization. I based the program on many of the threats we experienced on a daily basis, and the challenges users encountered, and sometimes fell for. As a result, much of the material addressed detecting and reporting social engineering attacks.

                                                            \nOn-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or \"idiot light\" if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle. \n

The constellation will consist of thousands of mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and orbit control teams. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion.\n

Additional test satellites and 60 operational satellites were deployed in May 2019. SpaceX launches up to 60 satellites at a time, aiming to deploy 1,584 of the 260 kg (570 lb) spacecraft to provide near-global service by late 2021 or 2022. SpaceX started a private beta service in the Northern United States in August 2020 and a public beta in October 2020, service beginning at high latitudes between 44° and 52° North.\n

In response, SpaceX has implemented several upgrades to Starlink satellites aimed at reducing their brightness during operation. The satellites are equipped with krypton-fueled Hall thrusters which allow them to de-orbit at the end of their life. Additionally, the satellites are designed to autonomously avoid collisions based on uplinked tracking data.\n

                                                            This episode is a response to hpr3367 by Andrew Conway and Dave Morriss. One of the topics they brought up was the thorny issue of page numbers in e-books. Most of the time you don't need to worry about page numbers in ebooks, if you're reading fiction for example. The whole point of an ebook is that the texts can reflow to fit the page no matter what size the screen is or what font-size you've chosen. This is a major accessibility feature of all e-book formats. One reason you might want to specify actual page numbers, though, is if you're dealing with a technical or academic book, and you need to be able to refer to specific passages in the book by page number, as you are expected to do in academic research. Or, as Andrew and Dave were discussing, you might need to create an index in your ebook that would send your readers back to specific pages like in a paper book.

                                                            \n\n

                                                            I've thought about this before but never really gotten into the weeds and figured out how to make it happen. In fact, when I was creating the new digital editions of the Counterpoint textbooks like I discussed in hpr1512, I actually took the trouble to put page number anchors through the entire thing, so that at a future date I would be able to enable real page numbers. This was a key part of the source file's infrastructure, which helped me quickly find the passages I was working on in my huge HTML file. Those anchors are not quite in the correct format for EPUB, but they are consistent and I will easily be able to write a script to fix them. I haven't done that yet, but now that I figured out how to do it on some smaller examples, this is on my to-do list.

                                                            \n\n

                                                            Anyway while I was listening to Dave and Andrew talk about this, I thought I remembered reading somewhere that in the newest ePub specification, EPUB 3, there was support for publisher's page numbers to deal with precisely this issue. Their discussion prompted me to see if I could make it work. I'm happy to report success, although with some qualifications, which I will get into.

                                                            \n\n

                                                            Converting to EPUB 3

                                                            \n\n

                                                            The first thing to do is to upgrade your ebook from EPUB2 to EPUB3. There are a couple of ways to do this. The way I did it was to use the ebook editor in a recent version of Calibre. When you open up the EPUB for editing, go to the Tools menu and choose Upgrade book internals. This will create the new navigation file nav.xhtml to replace the old toc.ncx file. You'll need to edit this new file later to enable the page numbers.

                                                            \n\n

                                                            Insert page anchors

                                                            \n\n

                                                            Next you need to put your page anchors in there. This could be very tedious if you haven't done any preparatory work, such as putting visible page numbers in plain sight in square brackets [21] the way I did for a couple of ebooks. It wasn't very elegant, but at least it was easy to find where the page breaks were. I have a Blather voice command that triggers a python script to create these things. Here's an example of page number anchor, which goes in the main text of the book wherever you want to insert a page number. This will not be visible to the reader inline. This is for page 57:

                                                            \n\n
                                                            \n<span epub:type="pagebreak" id="page57" title="57"></span>\n
                                                            \n\n

                                                            Page List in Navigation File

                                                            \n\n

                                                            Finally you need to put a page list in the new navigation file. This is simply an ordered list with hyperlinks to every page anchor that you put in your ebook. This will not be visible to the reader, but it's critical to making everything work. Here's a minimal example from my first attempt. This only covers Pages 122 to 126. This is the kind of page numbering you might need if you created an ebook from a five-page article from an academic journal that appeared in the middle of the volume.

                                                            \n\n\n
                                                            \n<nav epub:type="page-list" hidden="hidden">\n    <ol>\n        <li><a href="filename.html#page122">122</a></li>\n        <li><a href="filename.html#page123">123</a></li>\n        <li><a href="filename.html#page124">124</a></li>\n        <li><a href="filename.html#page125">125</a></li>\n        <li><a href="filename.html#page126">126</a></li>\n    </ol>\n</nav>\n
                                                            \n\n

                                                            I'm not sure it matters where you put this navigation block in the nav.xhmtl file, but I put mine between the table of contents and the landmarks blocks.

                                                            \n\n

                                                            Scripting the creation of page list

                                                            \n\n

                                                            It could be very tedious to create a page list like this, so of course I wrote a script to automate a lot of the heavy lifting. I'm sure Dave can write one that's more elegant than this, but this is what I came up with in about 5 minutes and it did the job, with the exception of putting the right URL for each link. I did a little bit of post-production to search and replace the URLs generated in the script with what I needed for the specific eBook. I think if you added a third command-line argument with a URL, you can solve this problem. The difficulty with larger books will be when you have more than one internal HTML file in the book, you will have to go through very carefully and make sure that the link goes to the correct file. I saved the script as pagelist.sh and put it in my $PATH.

                                                            \n\n

                                                            Command to run to generate a page list from pages 42 to 61:

                                                            \n\n
                                                            \npagelist.sh 42 61\n
                                                            \n\n

                                                            And here's the script:

                                                            \n\n
                                                            \n#!/bin/bash\n\n# grab beginning and ending pages from 1st and 2nd\n# CLI arguments, and specify a tmp file to put stuff\nstart="$1"\nend="$2"\nnavfile=/tmp/navfile.txt\n\n# put the top matter for the nav block\necho '<nav epub:type="page-list" hidden="hidden">' > $navfile\necho "    <ol>" >> $navfile\n\n# iterate through the page numbers making list item for each one.\n# should replace filename with your ebook's actual filename\nfor i in $(seq $start $end); do\n\techo "        <li><a href=\\"filename.html#page$i\\">$i</a></li>" >> $navfile\ndone\n\n# close out the list and nav block\necho "    </ol>" >> $navfile\necho "</nav>" >> $navfile\n\nexit 0\n
                                                            \n\nThen you just need to copy and paste what was generated from the script into your editor and make sure all of the URLs are correct, then stick that navigation block into the nav.xhtml file.\n\n

                                                            Conclusions

                                                            \n\n

                                                            So, once you have the page anchors and the page list in place in your EPUB3 ebook, everything should work. The problem is that so far the only ebook reader I have found that renders the page numbers correctly on the screen is the iBooks app on iOS. I tried it on my Kobo dedicated eReader, on the Marvin ePub reader on iOS and on Overdrive on Android, and none of them displayed my shiny page numbers. iBooks was the only one, but it did so perfectly after choosing \"show publisher page numbers\" on the table of contents menu. It was pretty magical. A quick internet search confirms that there is very little e-book reader or app support for displaying these page numbers.

                                                            \n\n

                                                            However, the embedded page numbers will still be useful if what you want to do is create an index that directs readers back to specific pages. On the one hand, indexes are not as critical as they used to be because you can search through the text of e-books very easily. What you can't do easily is browse an eBook the way you can browse a paper book index to see what topics might catch your eye. This might be something only academics do. It's not uncommon for an academic to pick up a book and flip right to the bibliography and the index!

                                                            Overview

                                                            \n

                                                            I live on my own, but I cook for members of my family from time to time. Each week we all get together and cook dinner for Wednesday and Thursday. I usually do the cooking but we are starting to share these duties for certain meals.

                                                            \n

                                                            In 2019 I thought it would be useful if I had some sort of random chooser to decide what next week’s meal was going to be. I wrote a Bash script called choose_meal, using a simple CSV file of meal names and the date last eaten to avoid choosing the same one too often. The shortcomings of this approach soon became apparent!

                                                            \n

                                                            It wasn’t long before choose_meal was rewritten in Perl. This time I decided to use a database, and chose SQLite to create it. My database contained just two tables, one for the meals themselves (called slightly confusingly 'meal_history'), and another for a record of the choices made (called 'meal_log') – the ability to produce historical reports seemed like a desirable feature!

                                                            \n

                                                            In 2019 the design of this system was very specific to our needs: one choice per week on a Wednesday. It was not something that could be used by anyone else – which seemed like a bad idea.

                                                            \n

                                                            In late 2020 and early 2021 the system was redesigned, as will be discussed in the detailed notes. In May 2021 a more general design was added to the public GitLab repository and the preparation of this show was begun.

                                                            \n

                                                            I had never intended this system to hold recipes. This was partly because I have built a collection of recipes I have constructed from various sources and amended as I have made them. I print these and keep them in a ring-binder for reference as I cook. In some cases the meals described in the database are multi-component ones (such as the dishes that make up a curry for example), so it doesn’t seem appropriate to hold these here.

                                                            \n

                                                            I might rethink this in the future however.

                                                            When I originally wanted a unified error reporting on the server-side, I made one huge type that enumerated all the possible error cases that could be reported:

                                                            \n
                                                            -- | Error codes for all errors returned by API\ndata ErrorCode\n    -- common error codes\n    = ResourceNotFound\n    | InsufficientRights\n    | FailedToParseDataInDatabase\n    -- errors specific to news\n    | SpecialEventHasAlreadyBeenResolved\n    | UnsupportedArticleType\n    | SpecialNewsExtractionFailed\n    | TriedToMakeChoiceForRegularArticle\n    -- errors specific to simulation state\n    | SimulationStatusNotFound\n    | DeltaTIsTooBig\n    | TurnProcessingAndStateChangeDisallowed\n    | SimulationNotOpenForCommands\n    | SimulationNotOpenForBrowsing\n    -- errors specific to people\n    | StatIsTooLow Text\n    | CouldNotConfirmDateOfBirth\n    | DateOfBirthIsInFuture\n    | FirstNameIsEmpty\n    | FamilyNameIsEmpty\n    | CognomenIsEmpty\n    | RegnalNumberIsLessThanZero\n    -- errors specific to new person creation\n    | AgeBracketStartIsGreaterThanEnd\n    | PersonCreationFailed\n    deriving (Show, Read, Eq)\n
                                                            \n

                                                            Then I had some helper functions to turn any value of that type into a nice error message:

                                                            \n
                                                            errorCodeToStatusCode :: ErrorCode -> Int\nstatusCodeToText :: Int -> ByteString\nerrorCodeToText :: ErrorCode -> Text\nraiseIfErrors :: [ErrorCode] -> HandlerFor App ()\n
                                                            \n

                                                            errorCodeToStatusCode was responsible for turning ErrorCode into http status code. For example StatIsTooLow \"intrigue\" would be 400. statusCodeToText would take this code and turn it into short error message given in http response. 400 would be Bad Request. errorCodeToText would give a bit more verbose explanation of what happened, StatIsTooLow \"intrigue\" would be mapped to \"Stat intrigue is too low\". Finally raiseIfErrors would take a list of ErrorCode and use these helper functions to turn them into a http response with correct status code, error message and json body detailing all errors that had happened:

                                                            \n
                                                            [\n    { code:\n        { tag: "StatIsTooLow"\n        , contents: "intrique"\n        }\n    , error: "Stat intrigue is too low"\n    }\n]\n
                                                            \n

                                                            There’s two tags: code, which contains machine readable details about the error and error, which contains error message that can be shown to user.

                                                            \n

                                                            While this worked fine, there was some problems with it. ErrorCode type was growing larger and larger and the module it was defined in was referred all over the codebase. Every time I added a new error message, all the modules that used error reporting had to be compiled and it was getting slow.

                                                            \n

                                                            Solution

                                                            \n

                                                            Breaking up the ErrorCode to smaller types and moving them to different modules would means less modules were going to built when I added a new error code. The problem was that raiseIfErrors :: [ErrorCode] -> HandlerFor App () wanted a list of ErrorCode and elements in a list have to be of same type.

                                                            \n

                                                            I started by splitting ErrorCode to smaller types. Each of the smaller error types have automatically derived toJSON and fromJSON functions for serializing them to and from JSON:

                                                            \n
                                                            data PersonCreationError =\n    StatIsTooLow Text\n    | CouldNotConfirmDateOfBirth\n    | DateOfBirthIsInFuture\n    | FirstNameIsEmpty\n    | FamilyNameIsEmpty\n    | CognomenIsEmpty\n    | RegnalNumberIsLessThanZero\n    deriving (Show, Read, Eq)\n\n$(deriveJSON defaultOptions ''PersonCreationError)\n
                                                            \n

                                                            That $(deriveJSON defaultOptions ''PersonCreationError) is template haskell call. Basically it invokes a deriveJSON function with PersonCreationError as parameter and compiles and splices the resulting code here. This is fast and easy way of generating ToJSON and FromJSON instances and avoiding having to write them by hand. It is very similar to how Lisp macros work.

                                                            \n

                                                            Then I defined a type class, that has functions for getting a http status code and a error message that can be shown to user. statusCodeToText I could use as is, without any modifications:

                                                            \n
                                                            class ErrorCodeClass a where\n    httpStatusCode :: a -> Int\n    description :: a -> Text\n
                                                            \n

                                                            I have to have instance of ErrorCodeClass defined for each and every smaller error type. Here’s an excerpt of PersonCreationError showing how it would look like:

                                                            \n
                                                            instance ErrorCodeClass PersonCreationError where\n    httpStatusCode = \\case\n        StatIsTooLow _ -> 400\n        CouldNotConfirmDateOfBirth -> 500\n...\n\n    description = \\case\n        StatIsTooLow s ->\n            "Stat " ++ s ++ " is too low"\n...\n
                                                            \n

                                                            A little note: description = \\case relies on lambda case extension. It is just a slightly different way of writing:

                                                            \n
                                                                description d =\n        case d of\n
                                                            \n

                                                            This allows me to turn values of these smaller error types into error messages that could be sent to the user.

                                                            \n

                                                            The second part of the solution is to figure out a way to put values of these smaller error types into same list. If a list is of type [PersonCreationError], it can’t contain values of CommonError and vice versa. Creating a wrapper like:

                                                            \n
                                                            data ECode a = ECode a\n
                                                            \n

                                                            doesn’t work, because then I would have elements of type ECode PersonCreationError and ECode CommonError, which are of different type. What I need, is a way to wrap all these different types into a wrapper that loses the type of wrapped value. Another problem is that I need to place constraints on what kind of values can be wrapped. I need them to have instances for ErrorCodeClass (for getting error information) and ToJSON (for serializing them into JSON). There’s several ways of doing this, but I chose to use generalized algebraic data types (GADTs for short):

                                                            \n
                                                            {-# LANGUAGE GADTs #-}\n\ndata ECode where\n    ECode :: (ErrorCodeClass a, ToJSON a) => a -> ECode\n
                                                            \n

                                                            Now type ECode has one value constructor, also named to ECode, which takes one parameter a. a can be anything, as long as there’s ErrorCodeClass and ToJSON instances defined for it. Calling this constructor will return ECode. If you compare this with the previous definition of ECode, you’ll notice two major differences:

                                                            \n
                                                              \n
                                                            • a is constrained to have specific type class instances
                                                              • \n
                                                            • resulting type is ECode, not ECode a
                                                              • \n
                                                            \n

                                                            The second part means that I can wrap different types into ECode and place them into a same list without problems. Type of that list is simply [ECode].

                                                            \n

                                                            But having a list of error codes wrapped in ECode isn’t going to do much to us. We need to be able to turn them into http status code, text and list of error messages. Luckily we have a type class just for that:

                                                            \n
                                                            instance ErrorCodeClass ECode where\n    httpStatusCode (ECode a) =\n        httpStatusCode a\n\n    description (ECode a) =\n        description a\n
                                                            \n

                                                            httpStatusCode of ECode is httpStatusCode of the value ECode wraps. Similarly description of ECode is description of the wrapped value.

                                                            \n

                                                            For turning ECode into JSON, I opted for hand written instance:

                                                            \n
                                                            instance ToJSON ECode where\n    toJSON (ECode a) =\n        object [ "HttpCode" .= httpStatusCode a\n               , "FaultCode" .= toJSON a\n               , "ErrorDescription" .= description a\n               ]\n
                                                            \n

                                                            This gives me complete control over how I want to report errors to the client.

                                                            \n

                                                            Final piece of the puzzle is raiseIfErrors function:

                                                            \n
                                                            raiseIfErrors :: [ECode] -> HandlerFor App ()\nraiseIfErrors errors = do\n    when (not $ null errors) $ do\n        let code = fromMaybe 500 $ errors ^? ix 0 . to httpStatusCode\n        let msg = statusCodeToText code\n        sendStatusJSON (Status code msg) $ toJSON errors\n
                                                            \n

                                                            If there are any elements in the passed in list, grab the http status code and text from the first element of the list. I was considering writing some sort of logic to deduce which error code to return in case there are more than one type in the list, but decided against it. There doesn’t seem to be any easy way to decide between HTTP 400 Bad Request and HTTP 500 Internal Server Error. So I just return the first one. Body of the response contains list of errors codes:

                                                            \n
                                                            [\n    { HttpCode: 400\n    , FaultCode: {\n        Tag: "StatIsTooLow"\n        , Contents: "intrique"\n        }\n    , ErrorDescription: "Stat intrigue is too low"\n    }\n]\n
                                                            \n

                                                            Since manually wrapping things in ECode gets tedious after a while, I defined function for each type of error that does that for me:

                                                            \n
                                                            statIsTooLow :: Text -> ECode\nstatIsTooLow s = ECode $ StatIsTooLow s\n
                                                            \n

                                                            Now, instead of writing ECode $ StatIsTooLow \"intrigue\", I can write statIsTooLow \"intrigue\". And if I ever decide to change internals of errors again, I can change how these functions are defined and hopefully don’t have to change each and every place where they’re being used.

                                                            \n

                                                            Different solution

                                                            \n

                                                            Another way to tackle this problem is to use records instead of algebraic data types:

                                                            Cutting to the chase:

                                                            \n

                                                            When getting into Magic the Gathering, it's easy to get overwhelmed and confused by choice. Instead of thinking about cards, I've learnt to think about the game mechanic roles that a deck needs to have satisfied, and then I look for cards that fill those roles.\n

                                                            \n\n

                                                            My list is by no means definitive, but I think these are the basic universal roles you need, regardless of how you play:

                                                            \n\n
                                                              \n
                                                            • Mana base: Land cards. These provide you with mana so you can play cards. For a 60 card deck, anticipate requiring about 24. In a later episode, I'll talk about additional ways to manage mana.
                                                              • \n
                                                            • General purpose: Creatures, enchantments, instants, artifacts, and so on. These are cards, costing a full spectrum of mana amounts (some you can play for 1 or 2 mana, others require 4 and 5 and more), that you need to populate your deck. These don't need to be anything special, unless you want to spend money for really fancy cards, but I assume you're not listening to me if you're a pro player.\n
                                                            • Card draw: You're going to deplete your hand unless you have cards that give you permission to draw more cards than just your allotted one-per-turn.
                                                              • \n
                                                            • Recursion: When you're forced to discard a card you really really wanted to play, you'll be glad to have some cards that grant you permission to bring that card back from your graveyard. This is called "recursion" by Magic players.
                                                              • \n
                                                            \n\n

                                                            There are other card types that can be useful, but they may be best for specific strategies. The ones I list here are, I believe, pretty universal.\n

                                                            \n\n

                                                            You can find lists of cards that fill specific roles with a simple Internet search. For instance, if you realize you have no cards that let you replenish your hand, you might search for "best cards to draw cards MTG" and get directed to a site like TappedOut.net or magic.wizards.com.

                                                            \n\n

                                                            Go to your local game store or an online vendor to buy just the cards you need. Because there are so many to choose from in any given category, you get to control the price. I have a rule for myself that do not spend over $2 on any single card.\n

                                                            When trying to fill roles, I generally aim to get 4 cards that do the thing I need. Sometimes I get exactly the same card 4 times, other times I get a variety of cards to fill the role. Either way, 4 usually feels like a good draw frequency for each role.

We need to take control for the purpose of collectively building a better world in which technology works in service to the good of human kind, protecting our rights and digital autonomy as individuals.

                                                            \n

                                                            We have become more reliant than ever on technology that we intertwine into every aspect of our lives. That technology is currently made not for us, those using it. Rather, it is for the companies who intend to monetize its use and whoever owns the associated copyrights and patents. Services are run via networked software on computers we never directly interact with. Our devices are designed to only function while broadcasting our intimate information regardless of whether the transmission of that information is necessary functionality. We generate data that we do not have access to, that is bought, sold, and traded between corporations and governments. Technologies we're increasingly being forced to use reinforce and amplify social inequalities. As schools and jobs go online, high speed computing, centralized services and Internet become inescapably necessary. Technology is designed and implemented to oppress, often with sexist, classist, and racist implications. Rather than being served by these tools, we are instead in service to them. These gatekeepers of our technology are not individual people or public organizations who think about the wellbeing of others, but instead are corporations, governments and others with agendas that do not include our best interests. Our technology has become the basic infrastructure on which our society functions, and yet the individuals who use it have no say or control over its function.

                                                            \n

                                                            It's time to change our digital destiny.

                                                            \n

                                                            We believe it is necessary for technology to provide opportunity for: informed consent of use; transparent development and operation; privacy and security from bad actors; interaction without fear of surveillance; technology to work primarily on the terms of the people using it; functionality inside and outside of connected networks; use with other services and other software, repair; and connection, and not alienation, from the technology itself and that which is created from it.

                                                            \n

                                                            We therefore call for the adoption of the following principles for ethical technology:

                                                              \nFrom conception through to public availability, technology must be in the service of the people and communities who use it. This includes a freedom from surveillance, data gathering, data sales, and vendor and file format lock-in. When it becomes apparent that the technology, as it is delivered, does not meet the needs of a given person, that person is able to change and repair their technology. Technology must have an option for use without an Internet connection.

People must be able to determine, either directly or through third parties, how the technology is operating and what information it is collecting, storing and selling. Additionally, there should be no punitive responses for declining consent -- practical alternatives must be offered, whether those are changes to the underlying technology or compatible updates from the original provider or from third parties.

                                                              When people discover that their technology is not functioning in their interest, or that the trade offs to use it have become too burdensome, they must have the ability to change what they are using, including the ability to replace the software on a device that they have purchased if it is not serving their interests and to use the technology while not being connected to a centralized network or choose a different network.

                                                              \n

                                                              Technology should not just be designed for the individuals using it, but also the communities of users. These communities can be those intentionally built around a piece of technology, geographic in nature, or united by another shared purpose. This includes having the ability and right to organize to repair the technology on and to migrate essential data to other solutions. Ownership of essential data must belong to the community relying on them.

                                                              \nBuilding technology must be done to respect the rights of people, including those of privacy, open communication, and the safety to develop ideas without fear of monitoring, risk, or retribution. These cannot be tacked on as afterthoughts, but instead must be considered during the entire design and distribution process. Services should plan to store the minimum amount of data necessary to deliver the service in question, not collect data that may lay the groundwork for a profitable business model down the road. Regular deletion of inessential data should be planned from the outset. Devices need to have the ability to run and function while not transmitting data. All of these requirements are to better ensure privacy, as everytime a device wirelessly transmits or otherwise broadcasts data there is opportunity for interference or theft of that data.

Technology must support us as we forge our own digital destinies as our connectivity to digital networks and one another changes in ways we anticipate and in ways we have yet to imagine. Technology makers and those who use this technology can form the partnerships necessary to build the equitable, hopeful future we dream of.

                                                            \n

                                                            Welcome to another episode of Hacker Public Radio. This episode is inspired by HPR episode 3157 entitled Compost by Klaatu. During the early 2000's, I lived in a single family home which had a number of oak trees around it. Between the trees, other foliage, and grass, there was a large amount of yard waste. While my city (Baltimore, MD in the US) will pick up your yard waste if you put it in bags by the curb [1], I would use the oak leaves as mulch, and did have a mulch pile of leaves and other yard waste. At that time, I thought about composting food waste, but there is a big issue with rats in Baltimore, and I didn't look into ways to compost. I just knew I couldn't randomly mix it into my mulch pile.

                                                            \n

                                                            I am currently living in a different house, without any oak trees, and not as much yard waste (particularly since we hire someone to mow the grass every couple weeks). After listening to the Compost episode, I was inspired to look into the best way to do it given my current living situation. The first thing I did was to look and see if there are any laws against composting in Baltimore City. The rat problem is big enough that the City purchased and distributed a large green plastic trash bin to every physical mailing address in the city. This is the bin you are required to use when putting out your trash. Given the situation, I wasn't sure it would be legal to do composting in your back yard. Much to my surprise, it is not only legal, but the city website has a web page on how to compost [2] and just recently started a pilot program for food scrap drop off with seven locations around the city [3].

                                                            \n

                                                            After determining I wasn't going to be a scofflaw, I went to the Internet to see what kind of bins are available for purchase. While Klaatu gives great suggestions for low cost composting bins, I wanted something that would look nice sitting out on a shelf for the small inside bin. I found the Utopia Kitchen Compost Bin [4]. The bin is made of stainless steel and has a volume of 1.3 gallons (4.9 liters). The lid is rounded and has a series of holes around the top. The inside of the lid holds a circular shaped charcoal filter. The combination of holes and charcoal filter capture any odors generated by the food scraps. It works amazingly well and even with onion scraps you need to stick your nose to the holes and inhale deep to smell anything when the lid is closed. It holds three to seven days worth of food scraps, most of which end up being coffee grinds. We have had this bin for 10 months, and the charcoal filter is still effective. There are replacement filters available for this bin, but you could also cut other charcoal filters to fit inside the lid.

                                                            \n

                                                            Given the potential rat and other small critter issues, I wanted the main, outside composter to be fully enclosed, and preferably not sitting directly on the ground. A quick search brings up a number of options, both composters that sit on the ground and ones that are tumbler style, which hang on a frame. I went with a tumbler style compost bin. This provided the desired feature of not being on the ground, and has the added advantage of making it easy to turn the compost every second or third day by just rotating the bin slowly for three or four full turns. I purchased the FCMP Outdoor IM4000 Tumbling Composter [5]. The composter is octagonal shaped column with two chambers inside it. This allows you to fill one chamber while the other side is finishing the composting process. There are also aeration holes for each chamber which can be open to different levels to moderate the amount of moisture. The combined volume of the two chambers is approximately 37 gallons (140 liters).

                                                            \n

                                                            So far I have been very happy with this combination. I just emptied a chamber for the third time. I do have a bit of an issue with the compost being overly damp. I have mixed some drier yard waste in from time to time and that does help, but have had times when parts of it get a little slimy. I have also run into issues with flies and other bugs living in the chamber for a while, but generally I don't see them outside of the composter, just when I open the door to add more material. Not ideal, but not so bad that I did anything about it. I have also found certain things do take extra time to compost, and usually need some manual help to break down. Pits of mangoes and avocados in particular along with corn cobs take a long time to break down. They do start to compost, and are easy to crumble in your hands, but keep their basic shape for a long while. Egg shells don't really break down, as Klaatu mentioned, but they do become very brittle and I crumble them up manually along with the pits and corn cobs. Another issue I have found with damper compost, particularly in cooler months, it doesn't heat up enough to decompose the seeds of some plants. This ended up being a pleasant surprise this summer after mixing in the first batch of compost in our little herb garden during the spring. We now have a combination of plumb and medium sized tomato plants and some kind of squash plant growing in it. If you don't want random plants growing in your yard or flower beds, do be careful when composting plants with seeds [6].

                                                            While it takes a little extra effort, composting does reduce the amount of garbage you are sending to the dump, and does reduce the smell of your kitchen trash bin. It also gives a rewarding feeling as you watch the material break down into a rich dirt, and then mix it into your garden or yard. I recommend giving it a try, and posting your experience as another episode of Hacker Public Radio.

                                                            Introduction

                                                            \n

                                                            I am in the process of rewriting some scripts I use to manage Magnatune albums. I’m a lifetime Magnatune member and have access to the whole music collection. I wrote a script for downloading albums and placing them in my ~/Music directory which I talked about in 2013 (show 1204). The original scripts are still available on GitLab and I know of one other person who made use of them!

                                                            \n

                                                            Since 2013 I have written a few other support scripts, for example one to manage a queue of albums I want to buy and download, and one which summarises the state of this queue.

                                                            \n

                                                            It’s this 'show_queue' script I am currently updating (called show_queue_orig, and available in the resources to this show). The original version of this script took Magnatune album URLs from a file (acting as a queue of stuff I wanted to buy), parsed out a piece of the URL and used it to grep a pre-prepared summary in another file. This file of summaries had been made from a master XML file provided by Magnatune (see update_albums on GitLab).

                                                            \n

                                                            Magnatune has moved away from this master XML file to a SQLite database in recent years, so I want to perform a database lookup for each URL to list its details.

                                                            \n

                                                            The first version of the new script wasn’t difficult to write: just extract the search data as before and run a query on the database using this data. I have included this script which I call show_queue_db_1 amongst the resources for this episode, so you can see what I’m talking about – and what I want to improve on. It felt bad to be performing multiple calls on the sqlite3 command in a loop, so I looked around for an alternative way.

                                                            \n

                                                            In April 2019 clacke did a show (number 2793) about the Bash coproc command.

                                                            \n

                                                            This command creates a subshell running a command or group of commands which is connected to the calling (parent) process through two file descriptors (FDs). It’s possible for the calling shell to write to the input descriptor and read from the output one and thereby communicate with whatever is running in the subshell.

                                                            \n

                                                            I was vaguely aware of coproc at the time of clacke’s show but hadn’t looked into it. I found the show fascinating but didn’t have a use for the feature at the time.

                                                            \n

                                                            To solve my need to show my Magnatune queue of future purchases, it looked as if a sqlite3 instance running in a subshell could be given queries one after the other and return the answers I needed.

                                                            A hospital in Spain did a double blind study, solid science. In this study, before any vaccines were available for covid, vitamin D3 made the difference between a 7.6% death rate due to covid, and a 0% death rate with vitamin D3. This YouTube video gets very technical, but tells the story.

                                                            Back in the 60s, body temperature's effect on fighting viruses was known, that knowledge was lost for a time because of scientists who spoke out, not knowing the whole story, but in 2003, in the aftermath of the previous covid outbreak, a doctor from China documented the need for body heat to fight off covid. Even so, medical professionals in New York set up a covid triage in Central Park during a season when the daytime temperature was in the 50s, and night time temperature was much colder. Just having a PhD behind your name doesn't make you right.

                                                            This episode is dedicated to tiny kernels driving operating systems also\n known as micro-kernels. While discussing the last 100 years of operating\n system design and implementation, our two aging heroes also shed some\n light on operating systems in general and their recent history (like fifty\n years). Unless you're a true OS nerd, you find the episode mildly\n refreshing and educational on the layers of software underneath your\n beloved applications controlling the hardware and other shenanigans. If\n you're an OS nerd, this episode may have the potential of closing your few\n remaining knowledge gaps (or something like this). A fun show for\n children of all ages and beyond.

So all\n beans will be spilled on one of the most popular Linux distros out there. Like its past, present\n and future. Never mind how Canonical makes its moolah and where this goes...

                                                            Install CentOS or Debian on a Raspberry Pi. I'm using CentOS, but I'll admit that Debian is the easier option by far.

                                                            \n

                                                            Do this on 3 separate Pi units, each with the same specs.

                                                            \n

                                                            Set hostnames

                                                            \n

                                                            You must have unique hostnames for each Pi. Without unique hostnames, your cluster cannot function.

                                                            \n

                                                            There are several \"kinds\" of hostnames, so to avoid confusion I change all of them.

                                                            \n

                                                            I use a simple naming scheme: k for \"kubernetes\" + an integer, starting at 100 + c for \"cluster\":

                                                            \n
                                                            $ sudo hostname k100c\n$ sudo sysctl kernel.hostname=k100c\n$ sudo hostnamectl set-hostname k100c\n$ sudo reboot\n
                                                            \n

                                                            Do this for each Pi. At a minimum, you end up with Pi computers named k100c, k101c, and k102c.

                                                            \n

                                                            Set verbose prompts

                                                            \n

                                                            When working with many different hosts, it's helpful to have a very verbose prompt as a constant reminder of which host you're connected to. Add this to the ~/.bashrc of each Pi:

                                                            \n
                                                            export PS1='\\[\033[1;32m\\]\\! \\d \\t \\h:\\w \\n% \\[\033[00m\\]' \n
                                                            \n

                                                            Install a Pi finder script

                                                            Install an LED blinker so you can find a specific Pi when you need one. This brilliant script is by Chris Collins for his article Use this script to find a Raspberry Pi on your network, which explains how to run it.

                                                            Install K3s on your control plane

                                                            \n

                                                            K3s is Kubernetes for IoT and Edge computing. It's the easiest, cleanest, and most serious method of getting Kubernetes on an ARM device. You can try other solutions (Microk8s, Minikube, OXD, and so on), but the best support comes from k3s.

                                                            \n

                                                            First, you must install k3s on one Pi. You can use any of your Pi units for this, but I use host k100c because it's the first in the sequence, so it feels logical.

                                                            \n
                                                            [k100c]$ curl -sfL https://get.k3s.io -o install_k3s.sh\n[k100c]$ chmod 700 install_k3s.sh\n
                                                            \n

                                                            Read the script to ensure that it seems to do what you expect, and then:

                                                            \n
                                                            [k100c]$ ./install_k3s.sh\n
                                                            \n

                                                            After installation, you're prompted to add some arguments to your bootloader. Open /boot/cmdline.txt in a text editor and add cgroup_memory=1 cgroup_enable=memory to the end of it.

                                                            \n
                                                            console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p3 rootfstype=ext4 elevator=deadline rootwait cgroup_memory=1 cgroup_enable=memory\n
                                                            \n

                                                            Reboot:

                                                            \n
                                                            [k100c]$ sudo reboot\n
                                                            \n

                                                            Once the Pi is back up, verify that your node is ready:

                                                            \n
                                                            [k100c]$ k3s kubectl get node\nNAME    STATUS  ROLES                  AGE\nk100c   Ready   control-plane,master   42s\n
                                                            \n

                                                            This Pi is the \"control plane\", meaning it's the Pi that you use to administer your cluster.

                                                            \n

                                                            Get the node token

                                                            \n

                                                            Obtain the control plane's node token. Thanks to k3s, this is autogenerated for you. If you not using k3s, then you must generate your own with the command kubeadm token generate.

                                                            \n

                                                            Assuming you're using k3s:

                                                            \n

                                                            Add your control plane hostname to your hosts file

                                                            \n

                                                            If you know how to manage local DNS settings, then you can use a DNS service to identify the hosts in your cluster. Otherwise, the easy way to make your nodes know how to find your control plane is to add the control plane's hostname and IP address to the /etc/hosts file on each node. This also assumes that your control plane has a static local IP address. For example, this is the host file of k101c and k102c:

                                                            \n
                                                            127.0.0.1  localhost.localdomain localhost\n::1        localhost6.localdomain6 localhost6\n\n10.0.1.100 k100c\n
                                                            \n

                                                            Verify that each host can find the control plane. For example:

                                                            \n
                                                            [k101c]$ ping -c 1 k100c || echo "fail"\n[k101c]\n
                                                            \n

                                                            Add nodes to your cluster

                                                            \n

                                                            Now you can add the other Pi computers to your cluster. On each Pi you want to turn into a computer node, install k3s with the control plane and token as environment variables. On my second Pi, for instance, I run this command:

                                                            \n
                                                            [k101c]$ curl -sfL https://get.k3s.io | K3S_URL=https://k100c:6443 K3S_TOKEN="${MYTOKEN}" sh -\n
                                                            \n

                                                            On my third and final Pi, I run the same command:

                                                            \n
                                                            [k102c]$ curl -sfL https://get.k3s.io | K3S_URL=https://k100c:6443 K3S_TOKEN="${MYTOKEN}" sh -\n
                                                            \n

                                                            Verify your cluster

                                                            \n

                                                            On your control plane, verify that all nodes are active:

                                                            \n
                                                            % k3s kubectl get nodes\nNAME        STATUS     ROLES                  AGE     VERSION\nk100c       Ready      control-plane,master   2d23h   v1.21.4+k3s1\nk102c       Ready      <none>                 21h     v1.21.4+k3s1\nk101c       Ready      <none>                 20h     v1.21.4+k3s1\n
                                                            \n

                                                            It can take a few minutes for the control plane to discover all nodes, so wait a little while and try the command again if you don't see all nodes right away.

                                                            \n

                                                            You now have a Kubernetes cluster running. It isn't doing anything yet, but it's a functional Kubernetes cluster. That means you have a tiny Pi-based cloud entirely at your disposal. You can use it to learn about Kubernetes, cloud architecture, cloud-native development, and so on.

                                                            \n

                                                            Create a deployment and some pods

                                                            \n

                                                            Now that you have a Kubernetes cluster running, you can start running applications in containers. That's what Kubernetes does: it orchestrates and manages containers. You've may have heard of containers. I did an episode about Docker containers in episode 1522 of HPR, you can go listen to that if you need to catch up. I've also done an episode on LXC in episode 371 of my own show, GNU World Order.

                                                            \n

                                                            There's a sequence to launching containers within Kubernetes, a specific order you need to follow, because there are lots of moving parts and those parts have to reference each other. Generally, the hierarchy is this:

                                                            \n
                                                              \n
                                                            • namespaces are the \"project spaces\" of kubernetes. I cover this in great detail in my GNU World Order episode 13x39.
                                                              • \n
                                                            • create a deployment that manage pods.
                                                              • \n
                                                            • pods are groups of containers. it helps your cluster scale on demand.
                                                              • \n
                                                            • services are front-ends to deployments. A deployment can be running quietly in the background and it'll never see the light of day without a service pointing to it.
                                                              • \n
                                                            • traffic, or exposure. A service is only available to your cluster until you expose it to the outside world with an external IP address.
                                                              • \n
                                                            \n

                                                            First, create a namespace for your test application to use.

                                                            \n
                                                            [k100c]$ k3s kubectl create namespace ktest\n
                                                            \n

                                                            The Kubernetes project provides an example Nginx deployment definition. Read through it to get an idea of what it does. It looks something like this:

                                                            \n
                                                            apiVersion: apps/v1\nkind: Deployment\nmetadata:\n  name: nginx-deployment\nspec:\n  selector:\n    matchLabels:\n      app: nginx\n  replicas: 2 # tells deployment to run 2 pods matching the template\n  template:\n    metadata:\n      labels:\n        app: nginx\n    spec:\n      containers:\n      - name: nginx\n        image: nginx:1.14.2\n        ports:\n        - containerPort: 80\n
                                                            \n

                                                            This creates metadata named nginx-deployment. It also creates a label called app, and sets it to nginx. This metadata is used as selectors for pods and services later.

                                                            \n

                                                            For now, create a deployment using the example:

                                                            \n
                                                            [k100c]$ k3s kubectl --namespace ktest \\\ncreate -f https://k8s.io/examples/application/deployment.yaml\n
                                                            \n

                                                            Confirm that the deployment has generated and started new pods:

                                                            \n
                                                            [k100c]$ k3s kubectl --namespace ktest get all\n3s kubectl --namespace ktest get all\nNAME                                  READY\npod/nginx-deployment-66b[...]   1/1   Running\npod/nginx-deployment-66b[...]   1/1   Running\n\nNAME                               READY\ndeployment.apps/nginx-deployment   2/2\n\nNAME\nreplicaset.apps/nginx-deployment-66b6c48dd5\n
                                                            \n

                                                            See the pods labelled with app: nginx:

                                                            \n
                                                            [k100c]$ k3s kubectl --namespace ktest \\\nget pods -l app=nginx\nNAME                                READY STATUS\nnginx-deployment-66b6c48dd5-9vgg8   1/1   Running\nnginx-deployment-66b6c48dd5-prgrf   1/1   Running\nnginx-deployment-66b6c48dd5-cqpgf   1/1   Running\n
                                                            \n

                                                            Create a service

                                                            \n

                                                            Now you must connect the Nginx instance with a Kubernetes Service.

                                                            \n

                                                            The selector element is set to nginx to match pods running the nginx application. Without this selector, there would be nothing to correlate your service with the pods running the application you want to serve.

                                                            \n
                                                            [k100c]$ cat << EOF | k3s kubectl \\\n--namespace ktest create -f -\napiVersion: v1\nkind: Service\nmetadata:\n  name: nginx-deployment\n  labels:\n    run: nginx-deployment\nspec:\n  ports:\n  - port: 80\n    protocol: TCP\n  selector:\n    app: nginx\nEOF\nservice/nginx-deployment created\n
                                                            \n

                                                            Verify that the service exists:

                                                            \n
                                                            [k100c]$ k3s kubectl --namespace ktest get svc nginx-deployment\nNAME       TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)   AGE\nnginx-deployment   ClusterIP   10.43.32.89   <none>        80/TCP    58s\n
                                                            \n

                                                            A Service is backed by a group of Pods. Pods are exposed through endpoints. A Service uses POST actions to populate Endpoints objects named nginx-deployment. Should a Pod die, it's removed from the endpoints, but new Pods matching the same selector are added to the endpoints. This is how Kubernetes ensures your application's uptime.

                                                            Notice that the Endpoints value is set to a series of IP addresses. This confirms that instances of Nginx are accessible. The IP of the service is set to 10.43.251.104, and it's running on port 80/TCP. That means you can log onto any of your nodes (referred to as \"inside the cluster\") to interact with your Nginx app. This does not work from your control plane, only from a node.

                                                            The only thing left to do now is to route traffic from the outside world.

                                                            \n

                                                            Exposing a deployment

                                                            \n

                                                            For a deployed application to be visible outside your cluster, you need to route network traffic to it. There are many tools that provide that functionality.

                                                            \n

                                                            Install metallb:

                                                            \n
                                                            $ k3s kubectl apply \\\n-f https://raw.githubusercontent.com/metallb/metallb/v0.10.2/manifests/namespace.yaml\n$ k3s kubectl apply \\\n-f https://raw.githubusercontent.com/metallb/metallb/v0.10.2/manifests/metallb.yaml\n$ k3s kubectl create secret generic \\\n-n metallb-system memberlist \\\n--from-literal=secretkey="$(openssl rand -base64 128)"\n
                                                            \n

                                                            Determine what network range you want your cluster to use. This must not overlap with what your DHCP server is managing.

                                                            \n
                                                            ---\napiVersion: v1\nkind: ConfigMap\nmetadata:\n  namespace: metallb-system\n  name: config\ndata:\n  config: |\n    address-pools:\n    - name: address-pool-0\n      protocol: layer2\n      addresses:\n      - 10.0.1.1/26\n
                                                            \n

                                                            Save this as metallb.yaml and apply the configuration:

                                                            \n
                                                            $ k3s kubectl apply -f metallb.yaml\n
                                                            \n

                                                            You now have a configmap for metallb, and metallb is running.

                                                            \n

                                                            Create a load balance service mapping your deployment's ports (port 80 in this case, which you can verify with k3s kubectl -n ktest get all). Save this as loadbalance.yaml:

                                                            \n
                                                            ---\napiVersion: v1\nkind: Service\nmetadata:\n  name: ktest-ext\n  namespace: ktest\nspec:\n  selector:\n    app: nginx\n  ports:\n    - protocol: TCP\n      port: 80\n      targetPort: 80\n  type: LoadBalancer\n
                                                            \n

                                                            This service selects any deployment in the ktest namespace with an app name of nginx, and maps the container's port 80 to a port 80 for an IP address within your address range (in my example, that's 10.0.1.1/26, or 10.0.1.1-10.0.1.62).

                                                            \n
                                                            $k3s kubectl apply -f loadbalance.yaml\n
                                                            \n

                                                            Find out what external IP address it got:

                                                            Open a web browser and navigate to the external IP address listed (in this example, 10.0.1.3).

                                                            Some time ago, I did some Hacker Public Radio episodes in which I ostensibly demonstrated how to create a PDF with Scribus. Secretly, I was actually demonstrating how unexpected payloads could be embedded into a PDF. Did the PDF I uploaded as part of that episode no longer contain a payload if the listener who downloaded it wasn't aware that the payload existed?

                                                            \n

                                                            I've been diagnosed by educators as a \"life long learner,\" which as far as I can tell is a buzzword referring to someone who takes pleasure in learning new things. In our world of technology, dear listener, I think this term is just \"hacker.\" And that's appropriate, because this is Hacker Public Radio you're listening to now, and listeners of this show tend to be people who enjoy learning and exploring new ideas, taking apart gadgets to see what makes them tick, reverse engineering code and data to understand how it gets processed, and so on.

                                                            \n

                                                            The thing about being a hacker or a life-long learner is that there's a lot of stuff out there that wants to be hacked, or learnt. And it turns out that it's just not possible to learn everything. Sometimes, you're out of your depth. It can be tricky to recognize when you're out of your depth, and I think there's a certain learn-able skill to knowing that you don't know something. There's a lot of value to this skill, because when you can recognize you don't have expertise on something, you're able to look around you and find someone who has. That's significant because you can learn from someone with expertise.

                                                            \n

                                                            In my own humdrum life, before getting a full-time job at a tech company, I was commissioned on several occasions to build out infrastructure for a video game development project, an indie radio station, a few different multimedia projects, and so on. When I took on those roles, I became the resident expert. People turned to me for the authoritative word on what technological solutions should be used. When I told them, they were more or less obligated to listen, because that was the role I'd been hired for. If they were to ask me what a workstation should run, and I said Linux, but they bought a Mac instead, then my role would be unarguably redundant. They could just as easily type the question into a search engine on the Internet, and ignore the result. Or they could roll a die, or whatever.

                                                            \n

                                                            In those cases, though, it's a question of my opinion compared to someone else's opinion. Both are valid. Because I was the architect, my opinion mattered more to the long-term plan, but if the long-term plan were to change from having a highly-available cluster for fast 3d model rendering to having workstations with a familiar desktop, then my opinion would be less valid.

                                                            \n

                                                            But there are some areas in life where opinions don't matter. Specifically, that area is science. But what is science, anyway? People talk about science a lot, but it took me a long time, especially as someone who largely came from an artistic background, to comprehend the significance of the term, much less how it worked.

                                                            \n

                                                            Forget about all the high school classes and pop dietitians and physicists. Science is a framework. It's a set of principles designed to help our human brains hack the world around us in a methodical and precise way. Instead of letting our opinions, which may or may not be relevant, influence conclusions and decisions we make, science looks at the results of controlled input and output. Wait a minute. \"Input and output\"? Those are words I understand. Those are computer terms!

                                                            \n

                                                            Yeah it turns out that computers are the product of science, and in fact building computers and programming computers is a form of Computer Science. Those are just words we made up, but they reveal a lot about what we computer hackers do all day. Computers don't understand the influence of opinion, or your force of will, or the power of faith. They just take input and produce output. They do this very reliably.

                                                            \n

                                                            I don't know whether you've ever tried, but it's really hard to make a computer. Comprehending how a CPU processes rudimentary electrical pulses to transform them into complex instruction sets is mind-bending, at least to me. I've sat down and thought about it critically. I've set up a few experiments, too. There's one you can do with dominoes, believe it or not, that can somewhat help you design a logic circuit. There's a Turing Machine you can build with Magic The Gathering cards. And an electronics kit that'll help you build an 8bit CPU. But even with all of those experiments, the open RISC-V CPU still eludes my comprehension.

                                                            \n

                                                            And just to be clear: back in 2008 or so, I was hired to stress test a RISC CPU to determine whether it was efficient at rendering massive amounts of video. I designed tests in an attempt to prove that a RISC CPU could not out-perform the latest Intel Core2duo, and could not achieve the goal (RISC is better, what can I say?) So my affinity for RISC is far from just a passing interest. But I can't build a RISC-V or even really explain how a CPU works.

                                                            \n

                                                            For that, I understand that there are experts. These aren't just people I call experts because they're labeled that way on their shirt pocket. They're experts because they're building the RISC-V, and it works. I met some of them back at OSS Con in 2019. I recognize their expertise, because they're proving their knowledge.

                                                            Let's say I approached the RISC-V booth with the preconception that x86 was superior. After all, why would most consumer computers be running x86 if it weren't the best? I might be skeptical if I were told that RISC-V is superior for some tasks. Could they have ulterior motives? Could they have been paid off by Big Silicon to lie about RISC's performance in order to hurt x86's marketshare? Sure, it could happen. And that skepticism is important. It's arguably part of the scientific process. Look at the results of an experiment, replicate the input and ensure that the output is reliably the same.

                                                            But you can't be sure until you've duplicated the experiments that make the claim in the first place. Unfortunately, this often requires some pretty controlled environments, and possibly some pretty high end equipment.

                                                            The bottom line is that I'm never going to get around to doing that, I'm never going to have access to those resources, and I'm never going to have the understanding I'd need to comprehend all the potential variables involved. In short, I just don't have the expertise. But I'm willing to trust the expertise of a lot of people from all over the world working on this project. I'm going to trust that because they all agree on similar findings, that what they're saying about the design and architecture of their CPU, that there's a high likelihood that their findings are correct.

                                                            The same goes, as it turns out, for biological sciences. No matter how many one-off experiments discover that cigarette smoking is beneficial to your health, the wider scientific consensus is that it's harmful. No matter how man \"free-thinkers\" on the Internet discover that Covid-19 is actually no worse than the common cold, the worldwide scientific community asserts that it's actually harmful, and medical staffs across the globe assert that increased cases of Covid-19 cause bed and healthcare shortages for everyone else. Somebody online may assert that it's an impossibly unified globe-spanning political plot, but that relies on a bunch of untest-able opinions and interpretations of reality that fall well outside any scientific framework.

                                                            \n

                                                            It seems to me that this line of speculation makes about as much sense as asking whether your computer can really still add numbers accurately. Couldn't it occasionally be lying to you? The device you're using to listen to my voice right now not to scramble what I'm saying and accurately play what I recorded in the first place is based on the same scientific principles used by those in biological sciences. We're feeding data into functions, whether the function is written in code, forged in silicon, or written on paper as a math formula, and we're observing the results. When every expert in their field, across the entire globe, agrees on the output, I think we do too. It's either that, or we'd better all go build our own 8bit circuits out of chickens and batteries and just start to rebuild.

                                                            So did the PDF I uploaded as part of the Scribus episode no longer contain a payload if the listener who downloaded it wasn't aware that the payload existed? Obviously not. If the listener lacked the foresight or expertise to investigate the PDF for a hidden file, then they could have posted an episode of their own about how my PDF was completely normal. They'd have been confident in their findings. But you and I know that whatever experiments they might have used to come to the conclusion that Klaatu was NOT a liar was, in the end, insufficient. The payload did exist, but it was just outside this imaginary listener's detection or comprehension.

                                                            Critical thinking is important. But at the same time, the scientific framework requires more than just critical thinking, just as building a RISC-V CPU requires more than just being a fan of reduced instruction sets. And solving the Covid-19 crisis takes a lot more than just critical thinking and a couple of backyard \"experiments.\" We're not in the Dark Ages any more, folks. Get vaccinated. Stay safe, and I'll talk to you next time.

                                                            \n

                                                            After recently reclaiming my Neuton EM 4.1 electric lawn mower from my parents, I needed to replace the battery to make it operational. This mower was purchased in the early 2000s, and replacement batteries for it are no longer available from the manufacturer. Thankfully replacement 12V 10A batteries are available through third parties.

                                                            \n

                                                            Replacing Parts

                                                            \n

                                                            I faced two issues with finding replacement parts. The Neuton mowers run at 24V and need batteries that can provide 10 amps of current. They come with a battery case that holds two 12V 10A batteries connected in series. The case holds the batteries and provides a connector and circuitry for a 24V DC charger. When I received the mower back from my parents, it didn't have a battery case with it. While the Neuton website is still online, and looks like you can order some accessories still, they no longer carry replacement battery cases or batteries. I was able to find just the case on EBay. I then found replacement batteries on Amazon.

                                                            \n

                                                            Installing the batteries in the case is simple. One side of the case has a lid. The lid is held in place by plastic notches on the bottom and two screws at the top. The screws have size 10 star heads. The batteries sit side by side in the case, with their terminals facing the lid. I connected the inner terminals (negative of one battery to positive of the other) with the jumper wire that came with the case. I then connected the outer terminals to the battery case terminal wires, slid the batteries all the way into case, closed, and fastened the lid.

                                                            \n

                                                            The batteries are currently charging. The red charging light did come on when I plugged in the 24V DC charger, and nothing has exploded yet, so I am optimistic I will be able to use the mower again shortly.

After overcoming the initial difficulty of finding a keyboard that would connect wirelessly to the Mac Mini while using the Guix installer and some network difficulties, he describes the installation steps.

                                                            Guix has a graphical text based installer. It is reminiscent of the mid to late 90s Debian installers. Even with its old school feel, the installer is very nice. It is well laid out, has good onscreen description for each step of the installation process, and provides ample configuration selections from language, to to key board layout, to desktop and software selection.

                                                            Introduction

                                                            \n

                                                            On today's show I test whether the battery replacement for my Neuton mower is a success. This is a follow up to episode 3443. After some audio recording difficulties with the blue tooth headset I used with my phone, we hear if the replacement was successful. Before I could test the battery, I needed to replace the mower key. I think it would have been simple to just jump the terminals with a wire and maybe some alligator clips to hold the wire to the key terminals, but I was worried this would not guarantee the wire shaking loose as I moved. I looked on EBay and found a replacement key for about fifteen dollars US, and decided it was worth the cost and the wait before trying out the mower.

                                                            \n

                                                            After putting the key in the mower, pulling and holding the safety levers, and then pressing the start button. The mower wouldn't start. I checked the key was set properly, and saw the green LED on the handle lit and indicating that power was available. I pulled the key and battery out, and then reseated both of them, checking once again that the power indicator was lit. After some fooling around with the safety levers and start button, I realized you had to push the start button and then pull and hold the safety levers for the mower to start. The mower runs well, and the cost of the batteries and key will even out over time from the savings on not paying for a lawn service.

                                                            Linux and BSD are open source operating systems, while macOS is not. Of these POSIX-compliant systems, only Linux has landed on Mars so far.

                                                            That's pretty casual and loses the visual impact of a table or a list. So alternately, you could summarize what's common and highlight differences:

Dodge is one of the Lighten Modes, while Burn is one of the Darken Modes, but I pulled them out for their own tutorial because they are not only closely related (inverse of each other), but also because I wanted to cover their use as Tool Modes in addition to Layer Modes. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

                                                            \n

                                                            I have been looking into the audio quality issues of my shows. I think I have found a solution to them. Unfortunately, this show was recorded before I discovered it.

                                                            \n

                                                            In today's episode, I take the audience along my adventure in backing up my laptop's hard drives. During recent OS updates, the kernel updates started to fall. In my efforts to resolve the problem, I made things worse – to the point I decided it was time to reinstall the operating system. To prevent any data loss, I chose Clonezilla to image the drives.

                                                            \n\n

                                                            The Clonezilla Live edition lets you boot into a ncurses menu driven system that walks you through the process of either backing up your hard drives or restoring a Clonezilla backup. Clonezilla backups save space by imaging only the data on your drives (for those filesystems it recognizes – otherwise it uses dd to do a sector-by-sector copy)

                                                            \n\n

                                                            Overall the process was very smooth, and, at the end, I was confident to move forward with wiping my main hard drive and reinstalling the operating system knowing I had a way to restore any lost data.

                                                            I did a show about why I do not listen to non-mainstream podcasts as much as I used to. For me two things happened: I switched from being in the car for 16 hours a week to being a remote sales person at home. So the 16 hours I listened to podcasts every week in the car went away. The second reason I reduced was that many of the podcasts I was listening to were presented by people who do not share my values. So I stopped listening to them. The third reason I listen less is the Army opened up the online book library to retired service members and I do a lot of audio books in the moment.

Although my zip code covers 139.56 square miles, the result is accurate enough for my needs. When my zip code was submitted, the web page did not refresh. This means that the client interface made an API call to the backend server.

From this data, it is possible to recreate the query. \nHowever, I took an even easier route, and right-clicked on the query in the Network tab, and selected Copy > Copy as cURL to get the request as a curl command complete with all necessary arguments prefilled. Since I didn't want to write my entire AQI fetching script in bash, I copied the curl command into a text file and ported the request to Ruby.

                                                            Hello, my name is Dave, and welcome to another exciting episode of Hacker Public Radio. It's been a couple of years since my last episode, and I know that HPR is running low on shows. As I have had this one in planning for some time now, I though this was the right time to get it finished.

                                                            \n

                                                            Main

                                                            \n

                                                            At the time of recording this, I've been an Amateur Radio licence holder for 6 months. I took the notion of studying and applying for my Foundation licence (the first of three stages to a Full licence) when I read a blog post by Jon Spriggs G7VRI, back in March, entitled Might Amateur Radio be a hobby for you? I saw a presentation by Jon at OggCamp in 2018 in Sheffield where he gave a whistle-stop tour of what Amateur Radio actually is, and how easy it is to get involved in it.

                                                            \n

                                                            As a bit of background, I was quite involved in the CB Radio scene back in the late 80s and early 90s - I was introduced to CB by my dad, whose handle was \"Screwball\", in the 70s... he had a CB rig in his car since as far back as I can remember. I picked up the hobby from him, by actually liberating him of his rig when he stopped using it. Unfortunately it got stolen from my car. C'est la vie. Yes, my handle back then was \"The Love Bug\" - in fact, it was whilst looking for an alternative to \"Kool Kat\" as a handle that I first used the moniker \"The Love Bug\" - probably in the mid-80s - and it just stuck.

                                                            \n

                                                            So, after reading Jon's blog post, and doing some research into Amateur Radio myself, a whole bunch of things happened at the same time: I bought my first radio - a Baofeng UV-5RTP [Amazon UK], I joined the Radio Society of Great Britain (not a requirement, but I would recommend it), signed up for Essex Ham's Foundation Training Course (not a requirement, but strongly recommended as it's geared around the examination, and it's free!)

                                                            \n

                                                            The training took 3 weeks (in my own time), and I applied for my exam as soon as the training was complete. The exam was an hour long, under as close to exam conditions as an online exam would allow, and I was told by the online system that I'd passed as soon as I submitted my answers. It then took a few days to get the confirmation of passing (and a certificate) in the post, which then allowed me to apply to Ofcom (the authority for the radio spectrum here in the UK) for my licence and callsign. I was able to choose the suffix of my callsign, and - as BUG was taken - I opted for TLB (for The Love Bug), and thus my callsign is - currently - M7TLB (Mike Seven Tango Lima Bravo). I say \"currently\" - I'm not allowed to change my callsign, however the callsign is specific not only to me but also to the fact that I'm a Foundation Licence holder. Therefore, when I go for my Intermediate and then Full licence, I'll get new callsigns for each one, each superseding the previous.

                                                            \n

                                                            Anyhoo, once I got my Foundation licence, I went out that Sunday to log some contacts, or QSOs. So I parked up at a high point near to here, put a small aerial on the roof of the car (so that I didn't warm up my head when transmitting), and started calling CQ - essentially a way of saying \"I want to talk to somebody\" - \"Seek You\". As part of the licence conditions, you are only permitted to make contact with other identifiable and identified amateurs... general broadcasts to whomever might be listening are prohibited. Except when calling CQ to initiate that contact.

                                                            \n

                                                            So I'd call out something akin to \"CQ, CQ, this station Mike Seven Tango Lima Bravo, Mike Seven Tango Lima Bravo Portable, calling CQ.\" The \"Portable\" indicates that I'm not at my home station location. It's also a good indication that my transmission might be variable due to the portable nature of the station.

                                                            \n

                                                            I was transmitting using 8 watts of power, two watts fewer than the limit of my license, but significantly lower than the 400 watts that I could be using as a Full licence holder, so my hopes weren't high. My first contact was with a chap just outside Caistor, Lincolnshire... about 38 miles direct from where I was based. He was also using a portable station, but with a directional beam antenna, meaning that both transmission and reception from his end was able to focus on my direction. So yeah, impressed!

                                                            \n

                                                            My second contact was also a portable station, located at a high-point by the Woodhead Pass, in Penistone, about 18 miles direct from where I was. This contact was the gift that kept on giving, as there were two other portable stations at the same location, so I got three contacts in the log for that one.

                                                            \n

                                                            Things went quiet after that one, so after a further 5 calls out, I figured that was my lot. Still, I was happy with four QSOs on my first day!

                                                            \n

                                                            Later the same day, I went out for my daily constitutional, so I figured I'd take the radio - with the standard short rubber-duck antenna, and an earpiece - with me. At least that way, I wouldn't look too silly, or a target to be fair. My intention was just to bounce around the frequencies and listen to conversations, rather than put out any CQs myself... I was in a residential area, so I didn't want to draw attention to myself.

                                                            \n

                                                            Whilst listening, I heard someone calling CQ and inviting respondents to a different frequency, so I followed and listened. There were a couple of contacts already there that I couldn't hear, so I waited for the initial contact to finish working the first. When he put out a call for whomever originally responded, I jumped in with my callsign, thinking that there was no way he would hear me. Consider that I was walking around town, in a reasonably built-up area, with probably the worst antenna I could have chosen for distance, and he wasn't exactly coming through strong. He responded to me directly, asking me to standby whilst he worked the other station that responded. Well, I was shocked to hear him say to the other contact that he was in East Yorkshire, about 33 miles from here! He was using a directional beam antenna which was pointing due west... whereas I am south-west of his location, so when you consider the other things I mentioned, the fact that he was also not pointing his antenna directly at me I was completely amazed that I was able to hold this relatively decent quality conversation with someone that far away. Well pleased was I.

                                                            Cost-wise, I should warn that Amateur Radio can be an expensive hobby, but it absolutely doesn't have to be. At a bare minimum, to get me \"on the air\" I bought the Baofeng (£42.99), and paid for my Foundation examination (£27.50), so a little over £70 overall. I actually bought a number of accessories for the radio, and joined the RSGB, but these are in no way required expenses. The standard radio on its own is more than sufficient to gain some decent contacts, as I hope I've proven with the success from that Sunday.

                                                            \n

                                                            Since then, I have bought an HF (or High Frequency) radio from India, it's a low-power model (or QRP) which is unlikely to get very far, but there are transmission modes that I can use that are specifically intended for low-power operation. My next big thing is to get an antenna up in the back garden along with a decent tuner so that I can actually use that radio!!

                                                            In this episode I take you along for the ride as I hack the wiring in a classroom podium so that I can show musical scores on the Elmo document camera while playing audio through the podium's laptop VGA audio source. Without this hack, the students could either see the score, or they could hear the music, but not both. This simple hack installing two jumper wires allows them to see the score and hear the music at the same time, which is important in my classes. I could already do this by using a PDF music score on my laptop while playing the audio file, but this allows me to use a paper score and audio from my laptop at once. It essentially acts as an audio splitter, sending the audio signal to two channels at once.

                                                            Layer Modes, sometimes called Blending Modes, allow you to combine layers in a variety of ways. We continue with the Darken Modes, except for Burn, which was covered in the previous tutorial. Darken modes do what they say on the tin, they make things darker, and so they are kind of the inverse of the Lighten Modes. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24. I also take the time to discuss image formats such as JPG, PNG, and RAW.

                                                            Mechatronics is code, electronics and mechanics working together as a system. I am weak in all 3, but have built mini battlebot style robots completely from scratch, with every chassis part, every motor and wheel, and every circuit that drives them sourced for free from junk like discarded printers, dvds, tvs, computers and UPS.

                                                            \n

                                                            I am calling this ethos and the resultant aesthetic, Post Apocalyptic Robotics, that is robots that can be built by reclaiming existing post consumer products to create something new.

                                                            \n

                                                            Currently they are confined to smooth surfaces like battlebot arenas, but more rugged terrain bots are currently also being worked on, and I want to work towards autonomous and swarm robots as well.

                                                            \n

                                                            The recipes I release here, can be followed by anyone to build their own robots and devices, by simply gathering the required scrap units or similar as described; then disassembling, then finally reassembling into a new meta technological device.

                                                            \n

                                                            I hope that others will do the same, and come up with their own innovations and new recipes that can be added to our incipient swarms of meta-technological bots as they evolve ever more sophistication.

                                                            Meteors, asteroids, comets. Cataclysmic solar flares, massive volcanic eruptions and earthquakes triggering massive tsunamis, social unrest, runaway climate change, ransomware and EMPs attacks striking electric grids, deadly viral pandemics, mass hysteria, big boats blocking waterways, obscured malware in a systemd update, management engines at the heart of CPUs providing backdoors to Intel and AMD hardware at root -3 privilege... what could go wrong there?

                                                            \n

                                                            There are a large number of looming events which could collapse technological society as it is, wiping out most of the internet and shipping and transport and hopefully maybe even the government.

                                                            \n

                                                            Tech Prepping is more important than food prepping

                                                            \n

                                                            While most survivalist and prepper types concentrate on stacking cans of beans, seeds, fuel and ammo, the robot prepper will also be hoarding books on pdf, component datasheets, software libraries, breakout boards and every post EOL electronics product they can get their hands on.

                                                            \n

                                                            In a semi apocalyptic scenario where the trucks stop rolling, a lot of people who save seeds will be able to grow food in their communities, so food won't be such a big deal.

                                                            \n

                                                            There might even be some that figure out how to make petroleum from wood like mrteslonian channel on youtube.

                                                            \n

                                                            But a real crux will be analog, digital electronics technology, IT and mechatronics. Those communities with working electronics, mechatronics, and information technology infrastructure, will be at a distinct competitive advantage. They will be able to leverage this in such things as automation of agriculture, from watering schedules to weed pulling along with many other applications that will make the PAR communities ascendant. All else being equal, PAR will be a force multiplier vs hostile neighbours starved of their slaveslabs swiping because facebook no longer exists, or remnants of the tyrannical state coming out of their DUMB bunkers and thinking they still have the right to rule.

                                                            It's a good thing then, that we have a boost up to a mechatronic technological society all around us in the electronic consumer devices that although they may be decrepit, soiled and/or dead, nonetheless contain a wealth of component parts -most of which are hardy enough to function for a very long time, components that can be reused in new applications.

                                                            \n

                                                            It's like there is a supply chain for robot factories all around us. It's not infinite but it is very plentiful at the moment. Sadly, our society is blind to the current and future worth of the technological legacy in our midst and the electronics recycling is electronics destruction.

                                                            One of this new meta technology's main antecedents is BEAM(Biology Evolution Aesthetics Mechanics) robotics, Mark Tilden's robot projects that eschewed microprocessors in favour of circuits built of discrete components that mimic biological nerves and can react to environmental stimuli. There is a nice archive of BEAM related documents on the solarbotics site.

                                                            \n

                                                            Mark Tilden even wrote a book called 'Junk Bots', so must have had some of the same ideas I have... but where Mark uses transistors as the nerves and brains, I am using arduino since microprocessors are now very inexpensive.

                                                            \n

                                                            The use of arduino is the only thing keeping my projects from being completely PAR, but one day wish to have entirely PAR

                                                            Thus right to repair and hardware hacking are thus two important aspects to utilizing the processors inside consumer products to run other operating systems for our use. Unless we hoard thousands of atmega328p chips, it will be difficult to find processors that we can use unless they have been liberated via techniques described by Valerio De Giampietro. Reusing processors from printers and other products is a goal for the future, but right now, let's have some fun.

                                                            FUN and Education The first arduino PAR battlebot I built - the herald/interceptor; is powered by 5 18650 cells from trashed laptops, powertrain is a custom hybrid relay/MOSFET H-bridge, and it is driven by four electric motors and wheels harvested from PA printers. It has IR remote control and is very fast to the extent that I had to add rubber bumpers to it to keep it and others safe.

                                                            \n

                                                            I departed somewhat from the PAR ethos, with added front and rear ultrasonic sensors, and an mp3 player powering a tv speaker. Hence, it is the herald/interceptor

                                                            I think it has an interesting road warrior cyberpunk aesthetic, with the grey steel, aluminum and black ABS parts, and but for the wheels; star wars for the bolted on look of it

                                                            Can we set up PAR tournaments where we can bring our bots and battle it out? Cost is no longer a barrier.

                                                            Obviously you are going to learn a lot building a robot and the best way to learn is by doing.

                                                            Alright, now that I have shown some of the important strategic and fun implications of PAR meta technology, by raiding trashed consumer electronics for their components: I hope at the very least that everyone hearing this never again take their post use electronics to one of those recycling centers where all those precious components are destroyed, instead of keeping it in your basement where it belongs. You'd do better taking it to a landfill where perhaps some future wretched mutant can discover and make use of it, than take it to electronics recycling.

                                                            Next episode I'll show you how to build your PAR laboratory and give you the ingredients to the herald/interceptor battlebot, but if you're already excited to get started you can order an arduino Uno or nano, or an arduino kit with a bunch of sensors like I did when I got started. You can also start gathering things like printers, tvs, dvds, UPS and other waste, and get a soldering station if you don't already have one.

                                                            \n

                                                            In the coming episodes I will share the detailed recipe for my first post apocalyptic battlebot style robot I built complete with arduino code, and will show you how to build your own robot for free except for the arduino*. I'll also do email tech support for anyone having problems.

                                                            \n

                                                            I also want to go further into other tech prepper archiving, in case all or large parts of the internet are no longer accessible, and this may be where you programming specialists might be able to help. They kind of gave me weird looks on the arduino forums when I asked for a way to download all the libraries but was finally able to beg a script that let me download a lot of them, if not all.

                                                            \n

                                                            Also, all the component datasheets would be handy... it seems it would be prudent to have datasheets on all the components and microprocessors that you possibly can, and to have all the software libraries it would be practical to archive.

                                                            \n

                                                            I'll also go into more aspects and implications of this exciting meta technology, and I hope you will join me in building post apocalypse robotics and mechatronics fun.

                                                            Text editors are highly subjective and highly opinionated commodities. Everyone is aware of infamous rivalry between users of Emacs and Vi/Vim. Every single text editor has its own strengths and weaknesses. At the end of the day it's the question of your personal preferences and muscle memory when it comes to default key-bindings. Both Emacs and Vim have a learning curve. Steepness of that curve depends on the person's background and interests. Hey, but today I'm not here to talk about Emacs and Vim. I'm here to talk about a simple, easy to use and almost ever present text editor called GNU nano. So what exactly is this nano text editor? Well, according to documentation available on GNU nano's website,

                                                            GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to \"emulate Pico as closely as is reasonable and then include extra functionality\".

                                                            \n

                                                            Pico and Pine email suites are still around so what was the need to create nano in the first place? The answer is license. Pico and Pine email suites nowadays are available under Apache-2.0 license but that always wasn't the case and this ambiguity in the original licensing terms of the Pico editor led to the creation of nano. It was first created in 1999 with the name TIP (an acronym for TIP Isn't Pico), by Chris Allegretta. The name was changed to nano on January 10th, 2000 to avoid a naming conflict with the existing Unix utility tip. The name comes from the system of SI prefixes, in which nano is 1000 times larger than pico. In February 2001, nano became a part of the GNU Project. BTW if you want to know more about SI prefixes, I'd highly recommend you to listen to HPR episode 3453 - Engineering notation by Ken Fallon.

                                                            nano is really small in footprint and is relatively easy to use compared to Emacs and Vim and perhaps this is the reason why you'd invariably find it already installed on almost all GNU/Linux distributions. If you have ever used nano before you might have noticed that it looks kinda boring; there are no line-numbers nor there is any syntax highlighting and spell-checking also seems absent. But this is not true. nano has all of these features and even some more like regex searches, indentation, multiple buffers, available at its disposal. Then why does it come across as a plain Jane? The short answer is, I honestly don't know! For some unknown and obscure reasons many of nano's cool features are disabled by default. This results in nano coming across as a plain Jane little text editor that is uncool. And as I mentioned earlier, that is not true. But worry not! It is so darn easy to unleash the true potential of nano and make it shine. Are you ready? Great! Let's do it together then!

                                                            \n

                                                            First thing we need to to do is create a file with the name .nanorc in the $HOME directory. Open your terminal emulator and run,

                                                            \n
                                                            touch $HOME/.nanorc\n
                                                            \n

                                                            We'd also need to create a directory called Nano_Backups in our Documents directory. To do so run the following command,

                                                            \n
                                                            mkdir -p $HOME/Documents/Nano_Backups\n
                                                            \n

                                                            Next open that .nanorc file and simply paste the following content in it,

                                                            \n
                                                            set atblanks\nset autoindent\nset backup\nset backupdir "/home/USERNAME/Documents/Nano_Backups"\nset boldtext\nset constantshow\nset cutfromcursor\nset indicator\nset linenumbers\nset magic\nset minibar\nset mouse\nset showcursor\nset softwrap\nset speller "aspell -x -c"\nset trimblanks\nset whitespace "»·"\nset zap\nset multibuffer\n\nset titlecolor bold,lightwhite,blue\nset promptcolor lightwhite,lightblack\nset statuscolor bold,lightwhite,green\nset errorcolor bold,lightwhite,red\nset spotlightcolor black,lime\nset selectedcolor lightwhite,magenta\nset stripecolor ,yellow\nset scrollercolor cyan\nset numbercolor cyan\nset keycolor cyan\nset functioncolor green\n\ninclude "/usr/share/nano/*.nanorc"\n\nbind ^Q exit all\nbind ^S savefile main\nbind ^W writeout main\nbind ^O insert main\nbind ^H help all\nbind ^H exit help\nbind ^F whereis all\nbind ^G findnext all\nbind ^B wherewas all\nbind ^D findprevious all\nbind ^R replace main\nbind ^X cut main\nbind ^C copy main\nbind ^V paste all\nbind ^P location main\nbind ^E execute main\nbind ^A mark main\nunbind ^K main\nunbind ^U all\nunbind ^N main\nunbind ^Y all\nunbind M-J main\nunbind M-T main\nbind ^T gotoline main\nbind ^T gotodir browser\nbind ^T cutrestoffile execute\nbind ^L linter execute\nbind M-U undo main\nbind M-R redo main\nbind ^Z undo main\nbind ^Y redo main\n
                                                            \n

                                                            You'll have to replace USERNAME in the line number four, set backupdir \"/home/USERNAME/Documents/Nano_Backups/\" with your actual username and then save this file.

                                                            \n

                                                            Wouldn't it be nice if the colors in nano were different for a normal user and a root user? Yes, for sure. To do so create an empty .nanorc file in the root's directory,

                                                            \n
                                                            sudo touch /root/.nanorc\n
                                                            \n

                                                            Next create the backup directory Nano_Backups in root's Documents directory. To do so run the following command,

                                                            \n
                                                            sudo mkdir -p /root/Documents/Nano_Backups\n
                                                            \n

                                                            Open that /root/.nanorcfile and paste this content in it and save the changes,

                                                            \n
                                                            set atblanks\nset autoindent\nset backup\nset backupdir "/root/Documents/Nano_Backups/"\nset boldtext\nset constantshow\nset cutfromcursor\nset indicator\nset linenumbers\nset magic\nset minibar\nset mouse\nset showcursor\nset softwrap\nset speller "aspell -x -c"\nset trimblanks\nset whitespace "»·"\nset zap\nset multibuffer\n\nset titlecolor bold,lightwhite,magenta\nset promptcolor black,yellow\nset statuscolor bold,lightwhite,magenta\nset errorcolor bold,lightwhite,red\nset spotlightcolor black,orange\nset selectedcolor lightwhite,cyan\nset stripecolor ,yellow\nset scrollercolor magenta\nset numbercolor magenta\nset keycolor lightmagenta\nset functioncolor magenta\n\ninclude "/usr/share/nano/*.nanorc"\n\nbind ^Q exit all\nbind ^S savefile main\nbind ^W writeout main\nbind ^O insert main\nbind ^H help all\nbind ^H exit help\nbind ^F whereis all\nbind ^G findnext all\nbind ^B wherewas all\nbind ^D findprevious all\nbind ^R replace main\nbind ^X cut main\nbind ^C copy main\nbind ^V paste all\nbind ^P location main\nbind ^E execute main\nbind ^A mark main\nunbind ^K main\nunbind ^U all\nunbind ^N main\nunbind ^Y all\nunbind M-J main\nunbind M-T main\nbind ^T gotoline main\nbind ^T gotodir browser\nbind ^T cutrestoffile execute\nbind ^L linter execute\nbind M-U undo main\nbind M-R redo main\nbind ^Z undo main\nbind ^Y redo main\n
                                                            \n

                                                            What we have just done is, we have enabled some useful features of nano and changed the default keybindings to the more familiar ones like Ctrl+C for copying, Ctrl+X for cutting, Ctrl+V for pasting and a bunch of other key combinations. We've also enabled automatic backing-up of documents. Backups will get saved in the user's Documents/Nano_Backups directory.

                                                            \n

                                                            Spell checker is enabled in nano via this configuration but to utilize it you'll have to install aspell and aspell-dictionary from your package manager.

                                                            \n

                                                            Kudos! We have turned a timid GNU nano into a powerful wildebeest. Try this configuration and if possible leave your feedback.

                                                            \n

                                                            A word of warning. Package maintainers often ship stripped down versions of nano so one of these features might not be present in your installation and in that case, nano will throw some errors and refuse to start. You have two choices in that scenario; first, disable that feature by deleting the corresponding line from .nanorc file. Your second option is to download the nano source code and compile it yourself with all the features intact. If I were you, I'd go with the second option as compiling nano is really simple and straightforward. Only extra packages that you will need are libncurses-dev and libmagic-dev.

                                                            I wanted to write a test to see that parameters passed to validatePatchApiPersonR are validated correctly. patchApiPersonR is used by client to do partial updates on a Person entity. There's three different cases I wanted to check:

                                                            Detour on equality

                                                            \n

                                                            Equality in Haskell works slightly differently compared to for example C#. There is no built in, default implementation that gets used when the programmer hasn't written their own. If you want to compare equality, there needs to be implementation specific to your data types. This is done by making an instance of type class Eq (https://hackage.haskell.org/package/base-4.15.0.0/docs/Data-Eq.html).

                                                            \n
                                                            class Eq a where\n  (==) :: a -> a -> Bool\n  (/=) :: a -> a -> Bool\n
                                                            \n

                                                            There's two functions: == for equality and /= for inequality. You need to implement either one.

                                                            \n

                                                            Back to problem

                                                            \n

                                                            ECode is our structured error code type and defined as follows (this is short recap of previous episode):

                                                            \n
                                                            data ECode where\n    ECode :: (ErrorCodeClass a, ToJSON a, Eq a, Show a) => a -> ECode\n
                                                            \n

                                                            It can wrap anything that has correct type class instances and you will always get ECode as a result. It hides the specific type of thing being wrapped and only functions defined in type classes are available.

                                                            \n

                                                            First try

                                                            \n

                                                            Peel away ECode and compare what's inside and compare wrapped values:

                                                            \n
                                                            instance Eq ECode where\n    ECode a == ECode b =\n        a == b\n
                                                            \n

                                                            This will lead into a error \"Couldn't match expected type ‘a’ with actual type ‘a1’. ‘a1’ is a rigid type variable bound by a pattern with constructor...\". This is because ECode can wrap many different types, there is no quarantee that you're comparing values of same type. The whole error is show below for reference:

                                                            \n

                                                            \n

                                                            Second try

                                                            \n

                                                            We can use Show to turn ECode into string and compare them. This is what I did initially.

                                                            \n
                                                            instance Eq ECode where\n    a == b = show a == show b\n
                                                            \n

                                                            While this works, it feels hacky. It relies on string representations being different. If you accidentally write Show instance in a way that produces same string with two different values, the comparison breaks down.

                                                            \n

                                                            Third time is a charm

                                                            \n

                                                            After pondering a bit, I asked myself a question \"When are two ECode equal?\". The answer I arrived is \"When they have same http status code and description.\" Then I could write yet different take on equality:

                                                            \n
                                                            instance Eq ECode where\n    a == b =\n        httpStatusCode a == httpStatusCode b\n        &&  description a == description b\n
                                                            \n

                                                            This states that to two ECode values are equal, if they have same httpStatusCode and description.

                                                            \n

We continue with the Contrast Modes, which are ways of combining layers that can heighten the contrast my making light pixels lighter and dark pixels darker. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

                                                            Hi to all HPR listeners this is a short show just to say Hi and a happy New Year to those in HPR land I may not have talked to over the Mumble marathon (and that is most of you). My main news is my new Juno PC which I got just before Christmas and It is a massive upgrade for me from my old Gen 3 i7 PC I was using. In real world tests it is about 5 times faster than my old PC and editing Audio and images is a breeze. I got the Brutus 5000 with a Ryzen 9 5900 CPU 32Gb RAM and a 1TB Nvme SSD. It came pre loaded with Ubuntu 20.04 but I installed Linux Mint 20.2 and after getting the details of the PPA for the Juno Drivers everything is working fine. Ports wise for a tiny PC it is OK but I have added a USB 3 powered Hub with 4 extra ports and in the new year will get one with a few more to help me tidy up the wiring snakes on the desk.

                                                            \n

                                                            For some reason it no longer sees any bootable USB drives at boot after pressing of the boot menu key so a bit of investigation is needed to get that to work again, but on the whole I am a happy camper.

                                                            Overview

                                                            \n

                                                            On Christmas Day 2021 at 12:20 UTC the James Webb Space Telescope was launched. This is the largest telescope ever sent into space and the project has been delayed for many years. The entire astronomical community was very nervous about the launch and about the phase that will follow as the telescope is set up for use.

                                                            \n

                                                            Andrew Conway was previously a professional Astronomer, and Dave is very interested in the subject as an amateur. They got together on Mumble to witness the launch, and the dialogue was recorded and is presented here.

                                                            The James Webb Space Telescope (JWST) is a space telescope developed by NASA with contributions from the European Space Agency (ESA), and the Canadian Space Agency (CSA). The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program. It is intended to succeed the Hubble Space Telescope as NASA’s flagship mission in astrophysics. JWST was launched 25 December 2021 on Ariane flight VA256. It is designed to provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observations of some of the most distant events and objects in the Universe such as the formation of the first galaxies, and allowing detailed atmospheric characterization of potentially habitable exoplanets.

                                                            \n

                                                            JWST’s primary mirror, the Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 meter (21 ft 4 inch) diameter mirror – considerably larger than Hubble’s 2.4 m (7.9 ft) mirror. Unlike Hubble, which observes in the near ultraviolet, visible, and near infrared (0.1–1.0 μm) spectra, JWST will observe in a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.3 μm). This will enable it to observe high-redshift objects that are too old and too distant for Hubble. The telescope must be kept very cold to observe in the infrared without interference, so it will be deployed in space near the Sun–Earth L2 Lagrange point, about 1.5 million kilometers (930,000 mi) from Earth. A large sunshield made of silicon- and aluminum-coated Kapton will keep its mirror and instruments below 50 K (−223 °C; −370 °F).

                                                            \n

                                                            The NASA Goddard Space Flight Center (GSFC) in Maryland managed the development and the Space Telescope Science Institute is operating JWST. The prime contractor was Northrop Grumman.

                                                            \n

                                                            Development began in 1996 for a launch that was initially planned for 2007 with a US$500 million budget. There were many delays and cost overruns, including a major redesign in 2005, a ripped sunshield during a practice deployment, a recommendation from an independent review board, the COVID-19 pandemic, issues with the Ariane 5 rocket and the telescope itself, and communications issues between the telescope and the launch vehicle. Concerns among the involved scientists and engineers about the launch and deployment of the telescope have been well-described.

                                                            \n

                                                            Construction was completed in late 2016, when an extensive testing phase began. JWST was launched 12:20 UTC 25 December 2021 by an Ariane 5 launch vehicle from Kourou, French Guiana and was released from the upper stage 27 minutes later. The telescope was confirmed to be receiving power, and as of December 2021 is traveling to its target destination.

                                                            Witnessing the launch

                                                            \n

                                                            Andrew and Dave came up with the idea of watching the launch and talking about it on Mumble. Although this was not originally planned, the audio was recorded, and is included here.

                                                            \n

                                                            Note: Dave’s audio had a background hum which has been reduced a little with Audacity’s notch filter. Hopefully it’s not too distracting.

                                                            \n

                                                            We were puzzled that the altitude of the final stage of the rocket plus telescope decreased during launch. See the link below to a YouTube episode from Anton Petrov explaining what was going on.

                                                            \n

                                                            In the context of orbital mechanics, Dave spoke of another mission which is heading to Mercury but passing by inner planets to adjust speed. The name couldn’t be recalled at the time, but it was BepiColombo which is taking a 7-year path to its destination.

                                                            At the time of preparing these notes (2022-01-02) the JWST is en route to the (Sun-Earth) L2 point, about 1 million miles (1.5 million kilometres) from Earth. Along the way it is preparing itself for use, deploying the features which were folded up or stowed away when it was being launched. See the deployment explorer site for details of what is happening.

The good news is that the system will do what you tell it to do. But the bad news is that it will do what you tell it to do. You have to tell it in the precisely correct way, and that means Syntax. And with a number of commands you can modify them using Switches. And where do you learn all about Syntax and Switches? Why, in the HELP system, of course!

                                                            Go to Settings. Usually via the pulldown menu from the top twice, and click the cog icon. Search for 'Build Number', it's usually in Click on 'About Phone' Click on 'Build Number' seven times.

                                                            \n

                                                            Go back and then search for 'Developer options' it's usually in the System section

                                                            \n

                                                            You'll need to turn on two features 'Android Debugging' and 'ADB over network'

                                                            \n

                                                            While we are at it, go back and then search for 'IP Address' it's usually in the About phone section. You should see a IPv4 address eg: 192.168.1.100. Make note of the IP address as we'll use it later.

                                                            \n

                                                            Using ADB

                                                            \n

                                                            To get help use the command adb help

                                                            \n

                                                            USB

                                                            \n

                                                            Plug your phone using a usb cable. There will be a notification and a popup to allow the connection.

                                                            \n

                                                            Run adb shell and all going well you should see your phone. Commands like ls, cd, and find work well. For example find /storage/self/primary/.

                                                            \n

                                                            Network

                                                            \n

                                                            Unfortunately if you unplug your phone you no longer have a connection to it, but you can enable network access via tcp. Leave your phone connected to USB and then tell it to use a TCP/IP connection with the command adb tcpip 5555.

                                                            \n

                                                            Then connect to the phone using the phones IP address and port 5555, adb connect 192.168.1.100:5555. It should reply with a connected to message

                                                            \n
                                                            $ adb connect 192.168.1.100:5555\nconnected to 192.168.1.100:5555
                                                            \n

                                                            Now commands like adb shell should allow you to access the phone even if it's not physically connected via usb.

                                                            \n

                                                            Multiple devices

                                                            \n

                                                            Got multiple devices then you can connect them all in the same way as shown above. The only issue is you need to tell adb which one you want to address.

                                                            \n

                                                            The first thing you need to do is list the devices

                                                            \n
                                                            $ adb devices -l\nList of devices attached\n192.168.1.100:5555   device product:XXXX model:XXXX device:XXXX transport_id:9\n192.168.1.101:5555   device product:YYYY:ZZZZ device:ZZZZ transport_id:14
                                                            \n

                                                            The important bit is the transport_id at the end. You can then use the adb command as normal but specifying the -t option

                                                            \n
                                                            -t: allocate a pty if on a tty (-tt: force pty allocation)
                                                            \n

                                                            So for example adb -t 14 shell would connect to phone YYYY

                                                            \n

                                                            So that's it for remote control from the shell, but what if you want to see and interact with the screen itself ?

                                                            \n

                                                            Remote screen sharing with scrcpy

                                                            \n

                                                            From Wikipedia

                                                            \n

                                                            scrcpy is a free and open-source screen mirroring application that allows control of an Android device from a Windows, macOS, or Linux desktop computer. The software is currently developed by Genymobile, which also developed Genymotion, an Android emulator.

                                                            \n

                                                            The source code is available on github. It's available via apt install scrcpy on Ubuntu. In Fedora you'll need to enable it from the copr repo.

                                                            \n
                                                            dnf copr enable zeno/scrcpy\ndnf install scrcpy
                                                            \n

                                                            With only one phone connected you can just type scrcpy and the screen will appear. Remember right click is power, and the mouse is your finger ;-).

                                                            \n

                                                            If you have multiple devices connected you can connect using scrcpy --tcpip=192.168.1.101:5555

                                                            \n

                                                            scrcpy is a wonderful tool that deserves a show in itself, but in short it lets you interact with your phone as if it was a VNC/Remote Desktop session. You can copy text from the phone as well.

                                                            \n

                                                            It allows for control of the screen, as well as screen recording.

We continue with the Inversion Modes, which in various ways invert the lightness and the color values of the component layers. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

Printers and other products can sometimes be tricky to take apart. There may not be any visible screws to remove. The case cover may just snap into place and sometimes it feels like you are going to break the part before it unsnaps. Be aware that the ABS can snap if you force it past its breaking point, it is strong but when it breaks it can have sharp edges. Be especially careful when taking apart laptop batteries. Try not to short any circuits, and watch out because the metal strips that connect the 18650 cells are very sharp. Use pliers and metal cutters and remember not to create any circuits with your metal tools!

                                                            The Compose key allows you to input any character or sequence of characters regardless what keyboard layout you use, by typing the Compose key followed by a sequence of other keys. To use it, you must activate it in your system and choose what key you want to serve as the Compose key.

WinCompose enables the compose key on that wretched environment. It comes with a ton of additional sequences, plus a fancy GUI for creating your own.

                                                            Per its man page, bash \"[...] looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.\" Conventions and policies of your local system will determine which, if any, of these files already exist.

                                                            \n

                                                            A word of caution: be aware that creating a new .bash_profile in your home directory could have the unintended side-effect of preventing the reading and executing of commands in a .bash_login or .profile file already present, changing further the behavior of subsequent logins.

                                                            There's certain amount of boilerplate code in my game that keeps repeating time after time. I can't quite remove it, but I can hide it with template haskell.

                                                            \n

                                                            I'll be using PlanetName as an example throughout the show. newtype is Haskell's way of defining a new type, that wraps around an old type. This lets us to give better meaning to the wrapped type. Instead of talking about Text, we can talk about PlanetName and we won't accidentally mix it up with StarName or ContentsOfAlexandrianLibrary. It comes with no performance cost at all, as the wrapping is removed during the compilation.

                                                            \n

                                                            Below is how our PlanetName is defined:

                                                            \n
                                                            newtype PlanetName\n   = MkPlanetName {_unPlanetName :: Text}\n   deriving (Show, Read, Eq)\n
                                                            \n

                                                            It has:

                                                            \n
                                                              \n
                                                            • type constructor PlanetName
                                                              • \n
                                                            • data constructor MkPlanetName
                                                              • \n
                                                            • single field _unPlanetName
                                                              • \n
                                                            • type for that field Text
                                                              • \n
                                                            • deriving clause, telling compiler to automatically generate Show, Read and Eq instances
                                                              • \n
                                                            \n

                                                            If it were wrapping a Integer, we would add Ord and Num instances too.

                                                            \n

                                                            These instances give us some basic functions that we can use to turn out value into String and back or compare two values to see if they're equal or not. Ord lets us compare their relative size and Num adds some basic arithmetics like addition and subtraction.

                                                            \n

                                                            Remember, type constructor is used when talking about the type (function signatures, declaring type of a value, etc.), while data constructor is used to create values of the type (\"Earth\", \"Mars\", etc.). isPlanet :: PlanetName -> Bool states that isPlanet function takes one parameter of type PlanetName and returns value of type Bool. planet = MkPlanetName \"Earth\" creates a new value planet, that has type PlanetName and which value is MkPlanetName \"Earth\".

                                                            \n

                                                            Boilerplate

                                                            \n

                                                            When PlanetName is defined, I need to add some instances by hand: IsString, ToJSON, FromJSON, PersistField and PersistFieldSql.

                                                            \n

                                                            IsString lets me use string literals in code, without having to call the data constructor. Compiler is smart enough to infer from context if string I typed should be PlanetName or something else.

                                                            \n

                                                            ToJSON and FromJSON are used to turn value to and from json for transferring back and forth between client and server. In json our value is just simple string, but we still need to program that transformation.

                                                            \n

                                                            PersistFieldSql tells Persistent (database layer I'm using) what type of database field should be created to hold this data in database.

                                                            \n

                                                            PersistField contains functions for serializing our value to database and loading it from there.

                                                            \n

                                                            Below is full code that I want to abstract out as much as I can:

                                                            \n
                                                            newtype PlanetName\n   = MkPlanetName {_unPlanetName :: Text}\n   deriving (Show, Read, Eq)\n\ninstance IsString PlanetName where\n   fromString = (MkPlanetName . fromString)\n\ninstance ToJSON PlanetName where\n   toJSON = (toJSON . _unPlanetName)\n\ninstance FromJSON PlanetName where\n   parseJSON = (withText "PlanetName") (return . MkPlanetName)\n\ninstance PersistField PlanetName where\n   toPersistValue (MkPlanetName s) = PersistText s\n   fromPersistValue (PersistText s) = (Right $ MkPlanetName s)\n   fromPersistValue _ = Left "Failed to deserialize"\n\ninstance PersistFieldSql PlanetName where\n   sqlType _ = SqlString\n
                                                            \n

                                                            Template Haskell

                                                            \n

                                                            Template Haskell is an extension that adds metaprogramming capabilities to Haskell. One can write function that generates Haskell code and call it in appropriate place in source file. During compilation the function gets executed and resulting code injected in source file. After this source file is compiled normally. If you have used lisp macros, this is the similar thing.

                                                            \n

                                                            Generating the code

                                                            \n

                                                            We want a function that can be called like $(makeDomainType \"PlanetName\" ''Text) and it will create all the boiler plate for us.

                                                            \n

                                                            The function is show below:

                                                            \n
                                                            makeDomainType :: String -> Name -> Q [Dec]\nmakeDomainType name fType = do\n    tq <- reify fType\n    case tq of\n        TyConI (DataD _ tName _ _ _ _) ->\n            selectDomainType name tName\n        _ -> do\n            Language.Haskell.TH.reportError "Only simple types are supported"\n            return []\n
                                                            \n

                                                            reify is interesting function. When called during compile time and given a name, it'll figure what the name refers to and construct datastructure that contains relevant information about the thing. If you were to give it name of a function, you would have access to code inside of the function and could introspect it.

                                                            \n

                                                            Here we're using tq <- reify fType to find out what kind of type our code should wrap. Code uses pattern matching to match TyConI (DataD _ tName _ _ _ _). This is referring to a type constructor. In all other cases (more complex types, functions and so on), code reports and error.

                                                            \n

                                                            Since code should support different types of types and the respective generated code differs, next there's check to find out what kind of code to generate:

                                                            \n
                                                            selectDomainType :: String -> Name -> Q [Dec]\nselectDomainType name fType\n    | fType == ''Text = makeTextDomainType name\n    | fType == ''Int  = makeIntDomainType name\n    | otherwise = do\n                    Language.Haskell.TH.reportError "Unsupported type"\n                    return []\n
                                                            \n

                                                            This uses guard clause to check if fType is Text or Int and call respective function to generate it. Again, if there's no match, code reports an error.

                                                            \n

                                                            I could have written a function that generates all the code, but that would have been pretty long and hard to maintain. Instead of that, I opted to split generation in parts. makeTextDomainType calls these functions, one at a time and combines the results together to form the final code to be generated.

                                                            \n
                                                            makeTextDomainType :: String -> Q [Dec]\nmakeTextDomainType name = do\n    td <- makeNewTypeDefinition name ''Text\n    si <- makeIsStringInstance name\n    tj <- makeToJSONInstance name\n    fj <- makeFromJSONInstanceForText name\n    mp <- makePersistFieldInstanceForText name\n    mps <- makePersistFieldSqlInstance name ''Text\n    return $ td ++ si ++ tj ++ fj ++ mp ++ mps\n
                                                            \n

                                                            Some of the functions called are specific for Text type, while others are written to work with Text and Int. The latter ones have extra parameter passed in to indicate which type of code should be generated.

                                                            \n

                                                            Actual code generation

                                                            \n

                                                            Now we're getting into actual code generation. First one is makeNewTypeDefinition, which generates code for newtype.

                                                            \n
                                                            makeNewTypeDefinition :: String -> Name -> Q [Dec]\nmakeNewTypeDefinition name fType = do\n    deriv <- derivClausForNewType fType\n    return $\n        [NewtypeD []\n                 (mkName name)\n                 []\n                 Nothing\n                 (RecC (mkName $ "Mk" ++ name)\n                       [(mkName $ "_un" ++ name, Bang NoSourceUnpackedness NoSourceStrictness, (ConT fType))])\n                 [ DerivClause Nothing deriv]]\n
                                                            \n

                                                            First step is to call derivClausForNewType to create deriving clause (we'll look into that just in a bit). The major part of the code consist of generating newtype definition. There's two ways for code generation: quoting (which works very similar to lisp macros) and writing abstract syntax tree by hand. No matter what I tried, I couldn't get the quoting work for newtype, so I had to write the AST out by hand. And as you can see, it's not particularly pleasant experience. Constructor names are short and cryptic and there's plenty of them there. Some major parts:

                                                            \n
                                                              \n

                                                            • then there's a list of tuples defining fields of constructor, which has only one element in our case
                                                              • \n

                                                            That's quite lot to write and keep track of. It's especially tedious to come back to code and figure out what it is exactly doing.

                                                            \n

                                                            Lets not forget our deriving clause:

                                                            \n
                                                            derivClausForNewType :: Name -> Q [Type]\nderivClausForNewType fType\n    | fType == ''Text = return $ (ConT . mkName) <$> [ "Show", "Read", "Eq" ]\n    | fType == ''Int = return $ (ConT . mkName) <$> [ "Show", "Read", "Eq", "Ord", "Num" ]\n    | otherwise = do Language.Haskell.TH.reportError "Unsupported type"\n                     return []\n
                                                            \n

                                                            Again we're using guard to check if we're working with Text or Int and in any other case signal an error. <$> is used to call (ConT . mkName) function to elements in list of strings, getting back a list of type constructors.

                                                            \n

                                                            Next step, we create IsString instance for turning string literals into our domain type.

                                                            \n
                                                            makeIsStringInstance :: String -> Q [Dec]\nmakeIsStringInstance name = do\n    [d|instance IsString $(conT $ mkName name) where\n            fromString = $(conE $ mkName $ "Mk" ++ name) . fromString|]\n
                                                            \n

                                                            Here I could get quoting to work. In the example, everything inside of [d| ... |] is quoted literally, ie. I don't have to bother with AST, but can just write in plain Haskell what I want the result to be. $ that is immediately followed with another symbol is used to unquote. $(conT $ mkName name) executes conT $ mkName name and splices result inside the quote. Because name is a String, we can create a new String by appending \"Mk\" at the start of it. This creates our data constructor MkPlanetName. Notice how we use conT when creating a type constructor and conE for applying data constructor.

                                                            \n

                                                            For transforming our domain type to and from json we need ToJSON and FromJSON instances. Generating them is very similar than generating IsString instance, but I have included them below for sake of completeness.

                                                            \n
                                                            makeToJSONInstance :: String -> Q [Dec]\nmakeToJSONInstance name = do\n    [d|instance ToJSON $(conT $ mkName name) where\n            toJSON = toJSON . $(varE $ mkName $ "_un" ++ name)|]\n\nmakeFromJSONInstanceForText :: String -> Q [Dec]\nmakeFromJSONInstanceForText name = do\n    [d|instance FromJSON $(conT $ mkName name) where\n            parseJSON =\n                withText name\n                    (return . $(conE $ mkName $ "Mk" ++ name))|]\n
                                                            \n

                                                            Next we'll take serializing to and from database. Since Persistent takes care of the details, it's enough that we have two instances that interface with Persistent. First one of them is PersistField as show below:

                                                            \n
                                                            makePersistFieldInstanceForText :: String -> Q [Dec]\nmakePersistFieldInstanceForText name = do\n    let constName = mkName $ "Mk" ++ name\n        constPatt = conP constName [varP $ mkName "s"]\n        pTextPatt = conP (mkName "PersistText") [varP $ mkName "s"]\n    [d|instance PersistField $(conT $ mkName name) where\n            toPersistValue $constPatt =\n                PersistText s\n\n            fromPersistValue $pTextPatt =\n                Right $ $(conE constName) s\n\n            fromPersistValue _ =\n                Left "Failed to deserialize"|]\n
                                                            \n

                                                            This has more code into it as the type class requires us to implement three functions. Imagine how tedious this would be to write out as plain AST. But thanks to quoting, we can write most of the code as it were regular Haskell and just splice in the parts that vary.

                                                            \n

                                                            First notable part in it is constPatt = conP constName [varP $ mkName \"s\"], which creates a pattern used in pattern matching. When toPersistValue is called with MkPlanetName s as parameter, our pattern matches and we have access to s. When then call data constructor PersistText s and let Persistent to save this newly created value into database.

                                                            \n

                                                            Second pattern in the code is conP (mkName \"PersistText\") [varP $ mkName \"s\"] and we use it in fromPersistValue function. So when that function is called with PersistText s, our pattern matches and we have access to s. Which we then use to call MkPlanetName s to construct our domain type. If fromPersistValue would be called with something else, say numeric value from database, fromPersistValue _ pattern matches and we'll report an error. This normally shouldn't happen, but it's good practice to always cover all patterns, otherwise we get a nasty runtime exception and whole program grinds to halt.

                                                            \n

                                                            Last piece in our long puzzle is PersistFieldSql, which tells Persistent the type of the backing field in database.

                                                            \n
                                                            makePersistFieldSqlInstance :: String -> Name -> Q [Dec]\nmakePersistFieldSqlInstance name fType = do\n    let typeName = mkName name\n    let backingType = selectBackingSqlType fType\n    [d|instance PersistFieldSql $(conT typeName) where\n            sqlType _ = $backingType|]\n\nselectBackingSqlType :: Name -> ExpQ\nselectBackingSqlType fType\n    | fType == ''Text = conE $ mkName "SqlString"\n    | fType == ''Int  = conE $ mkName "SqlInt64"\n    | otherwise = do Language.Haskell.TH.reportError "Unsupported type"\n                     return $ ConE $ mkName "SqlString"\n
                                                            \n

                                                            This is probably starting to look familiar to you by now. We create instance of PersistFieldSql for our domain type. For Text we want to save data as SqlString and for Int we use SqlInt64. The actual, concrete and definite, column type is actually selected by Persistent based on this information. Persistent supports different kinds of databases, so it'll take care of mapping this information for the actual database product we're using.

                                                            \n

                                                            Using template Haskell can cut down amount of boiler plate code. It also lets you create new abstractions that might not be possible with the tools offered by regular Haskell. All this is nice until things don't work as planned and you have to figure out why. Debugging complicated template Haskell, especially if written by somebody else, can be tedious.

                                                            This is a story of a laptop with two power problems.

                                                            \n

                                                            The first and less severe is that sometimes the charging of the battery will get stuck at a certain percentage. This is not simply due to the effect commonly found with aging batteries but a fault with the laptop's charging hardware. A full reset of the charging system can fix it, which for this ASUS Zenbook UX550vd laptop requires a long press — meaning 40 seconds — from its shutdown state.

                                                            \n

                                                            The second and more serious issue is that the laptop thinks that it is plugged into AC power even when it is running only on battery. I ruled out an operating system or software issue because the issue remains whether running GNU/linux or Windows. The problem is serious because the power management software, in my case in KDE, will not respond to critically low battery levels by suspending or gracefully shutting down. It may be that a sudden loss of power damaged the previous SSD in this laptop, which was the subject of HPR 3428.

                                                            \n

                                                            My first attempt to fool KDE into seeing accurate battery information under /sys/class/power_supply/BAT0 using an overlay filesystem failed presumably because KDE's power system is listening out for some kind of event rather than simply monitoring those files. My second and successful attempt involved writing my own bash scripts run by cron to monitor battery levels and initiate actions when they got too low. There were errors with comedic consequences along the way. In fact, while writing these shownotes after I finished recording the audio, the laptop suspended itself because of a bug in my script - I used le (less than or equal to) rather than lt (less than) in my test for a change in the battery charge leading to unintended and fun consequences when the battery was fully charged.

                                                            Layer Modes, sometimes called Blending Modes, allow you to combine layers in a variety of ways. We continue with the HSV Components Modes, which brings us to yet another color model, in this case the Hue, Saturation, and Value model. We've already looked at RGB, which is the model used for most broadcast and online uses, and the CMYK model which is used for printing. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

                                                            All audio is mono. I used Audacity to record on my laptop at 44.1kHz. For the desktop mic I had to resort to using my son's desktop Windows 10 PC and Windows recording app which defaulted to 48kHz and I think it was the app rather than the mic that resulted in the surprisingly poor quality. It definitely sounds like some kind of noise gate is being applied but I didn't dig around to see what settings were available. For my phone's built-in mic I used Samsung's voice recording app which I presume came pre-installed on the phone. Recording via bluetooth on an android phone turned out to be tricky as the OS only wants you to use a bluetooth microphone for calls however I found an app called Bluetooth Headset Voice Recorder and then enabled call audio on bluetooth and was able to record (the rubbish) audio.

I did however tweak the gain on each track manually so that they were about the same volume.

                                                            \n

                                                            I write a moderate number of Bash scripts these days. Bash is not a programming language as such, but it’s quite powerful in what it can do by itself, and with other tools it’s capable of many things.

                                                            \n

                                                            I have enjoyed writing such scripts for many years on a variety of hardware and operating systems, and Bash is my favourite - partly because Linux itself is so flexible.

                                                            \n

                                                            This is just a short show describing three things I tend to do in Bash scripts to assist with some tasks I find I need to undertake.

                                                            1. Generate Bash variables from a text file - usually output from a program

                                                            2. Fill Bash arrays with data from a file or other source
                                                              3. \n
                                                            3. Use environment variables to control the Bash script’s execution
                                                              4. \n

                                                            In this episode, Rho`n unboxes his new PineTime smart watch development kit, and gives his initial impressions. The development kit consists of two watches. One watch is fully assembled and ready for daily use. The other watch is disassembled, consisting of a watch band, the watch back cover, and the assembled display, system on a chip (SOC), CPU, and battery. The kit also comes with a serial cable for connecting from your computer to the SOC.

                                                            I found the gladOS voice funny, hence I included that one, but these are the best sounding to my knowledge so far.

                                                            \n

                                                            I have seen that with there will be a new mimic release version 3 soon, which has a really great voice. And example with the voice of Alan Pope mycroft_demo. And synesthesiam who's working on these projects said that there will be hopefully a model, which can be trained with actual voice, which would fine tune the voice to sounds more like someone else.

We continue with the LCh Components Modes, which brings us to yet another color model, in this case the Hue, Saturation, and Value model. We've already looked at RGB, which is the model used for most broadcast and online uses, and the CMYK model which is used for printing, and in the previous tutorial we looked at the HSV model. This wraps up our look at color models, and also concluded our look at Layer Modes (or Blending Modes). These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

                                                            \n

                                                            This will create directory treasure-dungeon and initialize it by using rio template. rio is a standard library that I have recently started using. There's a tutorial available if you want to learn more about it. We'll cover only very basics while writing the game.

                                                            \n

                                                            Next step is to modify the project settings for the project that was created for us. Have a look at license file and change that to your liking. Then open up package.yaml and edit some of the metadata:

                                                            I have a repository at codeberg if you want to have a look what settings I ended up with.

                                                            \n

                                                            stack.yaml

                                                            \n

                                                            Having finished with package.yaml, save it and start editing stack.yaml. Here we change only one setting: - resolver: lts-18.27, this specifies which set of libraries to use. These are fetched from Stackage.

                                                            \n

                                                            Final step is to edit README.md to suit your needs.

                                                            \n

                                                            Using stack

                                                            \n

                                                            Now we can work on our project. Lets start by building it: stack build. This will build the example code. There's one library and one executable there. If everything went correctly, we can start our executable with stack exec -- treasure-dungeon. This should print a little message on screen and exit. We can also turn on verbose logging, by starting the project with stack exec -- treasure-dungeon --verbose 2> log.txt.

                                                            \n

                                                            Another useful command is stack test, which will compile and run tests for the project. There's couple simple ones as an example created by the template.

                                                            And if you want to clean up your project of intermediate files and exes, you can use stack clean.

                                                            Final thing before finishing, let's have a look at the project structure. There's three directories: app, src and test.

                                                            \n

                                                            app contains code for our executable. This is where we will be placing big portion of the code, mainly one that deals with user interactions.

                                                            \n

                                                            src contains code for our library. This is where we will be placing code that codifies rules of the game. We want to keep this part of the code oblivious about outside world, like screens, user input and such.

                                                            \n

                                                            test this is where tests live. We aren't going to do much with them most likely.

                                                            \n

                                                            In closing

                                                            \n

                                                            We started our card game project. It doesn't do much yet, but we already have an executable that we can build and run. Next time we'll look into how to roll a new character and get them equipped before venturing into treasure dungeon.

                                                            Introduction

                                                            \n

                                                            I’m writing a script to process image files sent in by HPR hosts with their shows. One of the things the script does is to strip Exif metadata from such images. That’s because this metadata may contain details that could identify the creator of the image - their camera, their location, and other things. Many people will be alert to this, but in case anything slips through it seems a courtesy to anonymise images sent to HPR.

                                                            \n

                                                            As I was implementing this I realised that one piece of Exif data: 'Orientation', can’t just be removed. Sometimes images are created with a particular orientation by the camera but are written with an Exif orientation setting that shows another orientation. If this is just removed the image might be shown wrongly.

                                                            \n

                                                            This short episode describes the journey I had learning about this issue and finding how to get round it.

                                                            \n

                                                            The Problem

                                                            \n

                                                            A show was sent in early March 2022 which had three images with orientation values in the Exif metadata. They had apparently been taken with one orientation but were being rotated for viewing.

                                                            \n

                                                            I later discovered that the orientation setting can be viewed with the exiftool command:

                                                            \n
                                                            $ exiftool -orientation testimage.jpg\nOrientation                     : Rotate 90 CW
                                                            \n

                                                            You can find information about the Orientation tag on the ExifTool web site.

                                                            \n

                                                            The actual image in this case is rotated 90° anti-clockwise (the top of the image is to the left) and this needs to be reversed. The setting 'Rotate 90 CW' causes it to be displayed after rotating 90° in the clockwise direction. The actual value for this setting is 6.

                                                            \n

                                                            The problem is that removing all the Exif data causes such an image to revert to its raw state as explained below.

                                                            \n

                                                            \n

                                                            It took me a little while to understand this problem because I couldn’t find a good explanation of what was going on.

                                                            \n

                                                            I found a repository on GitHub which would take a picture and generate all of the possible Exif orientations from it. I used it to generate pictures from one (a thumbnail) I used in an old HPR show. Here’s the original picture with an orientation setting of 6 (Rotate 90 CW), and then with the Exif metadata removed.

                                                            \n

                                                            I found and installed some tools:

                                                            \n
                                                              \n
                                                            • jpegexiforient - reads or writes the Exif Orientation Tag
                                                              • \n
                                                            • exifautotran - transforms Exif files so that Orientation becomes 1
                                                              • \n
                                                            • jpegtran - lossless transformation of JPEG files
                                                              • \n
                                                            \n

                                                            Note that these only operate on JPEG images.

                                                            \n

                                                            The exifautotran tool is a shell script that uses jpegexiforient to find the orientation and jpegtran to undo whatever rotation (or other transformation) has been defined.

                                                            \n

                                                            Reading the exifautotran script helped me understand all of this, but I did not use these tools in the end.

                                                            \n

                                                            In the script I had written to manage images I also needed to do other image operations:

                                                            \n
                                                              \n
                                                            • interrogate the image to find its size to determine whether a thumbnail was needed
                                                              • \n
                                                            • make a thumbnail if necessary
                                                              • \n
                                                            \n

                                                            To do this I had started to use the GraphicsMagick package.

                                                            \n

                                                            This package actually caters for the orientation transformation I wanted to perform and can handle many image types, not just JPEG.

                                                            \n

                                                            The technique is to use the command 'gm convert' with two options:

                                                            \n
                                                              \n
                                                            • -strip - remove all profiles and text attributes from the image

                                                            • -auto-orient - orient (rotate) the image so it is upright; adjusts the image orientation so that it is suitable for viewing

                                                            \n

                                                            Example:

                                                            \n
                                                            gm convert -strip -auto-orient sideways_pic.jpg normal_pic.jpg\n\n
                                                            \n

                                                            Running this on the images in question removed the Exif orientation after having rotated the pixels of the image to the 'Horizontal (normal)' state.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            I have modified my picture management script to use this technique, and so far it seems to do the job perfectly. It has to be admitted that images with Exif orientation metadata are rare though.

                                                            \n

                                                            The GraphicsMagick documentation indicates that the transformations needed to generate an upright image could cause problems with some images, so we will be alert to any issues. For the moment, it looks as if the problem is largely solved.

                                                            \n

                                                            Personally, I gained several things from this journey of discovery:

                                                            \n
                                                              \n
                                                            • I ended up understanding images a bit better.
                                                              • \n
                                                            • Using exiftool to examine these images helped me to understand the power of this tool1.
                                                              • \n
                                                            • I also discovered that if opened the example image with Gimp it spotted the orientation issue and asked if I wanted it to perform the transformation discussed above.
                                                              • \n
                                                            • I installed a KDE image tool called ShowFoto and it also reported the fact that the image existed in two forms, in the same way, and allowed Exif editing.
                                                              • \n

                                                            1. For the record, removing all Exif data with exiftool is achieved with the command:

                                                              \n
                                                              exiftool -all= image.jpg

We've already covered it before but there is a brief refresher about the hydraulic, and pneumatic systems before we get to changing the plate itself. As always be sure you follow the safety instructions provided by the manufacturer.

                                                            Reportedly the problem was resolved on March 30th but the next day it returned and at the time of writing the HPR site is still unavailable.

                                                            As reported on the last Community News all shows in the range 1-870 had been uploaded except for shows hpr0001 - hpr0003. Shows hpr0001 and hpr0002 had been \"blocked\" by existing non-HPR items from over 8 years ago, with the names we were going to assign. Show hpr0003 seemed to have been an early attempt to upload blocks of shows since it contained the audio for shows 1-9, but no notes.

Show hpr0003 has now been resolved by replacing the contents with the appropriate transcoded audio and the notes have been added to it.

The acronym NVM stands for non-volatile memory, which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCI Express (PCIe) add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices

Being an obvious piece of blatant technology\nmarketing, the Linux Inlaws are still waiting for the funds to arrive from the\nRust Foundation :-) (@Foundation: If you want to get in touch please send\na mail to sponsor at linuxinlaws eu). Jokes aside, the episode give a short\noverview of this new programming language without going into deeper technical\ndetails as this podcast is only the usual four hours long.

This is not just about organizing files, though that is certainly a part of it, but also about keeping your system running smoothly and recovering lost files in some circumstances.

The acronym NVM stands for non-volatile memory, which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCI Express (PCIe) add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices

                                                            Most of the time we work with JPEG images because that is the most common format for digital images. They have the virtue of decent quality combined with smaller file size, and so won't fill up your storage quite as fast. But if you want the highest quality you have to work with unprocessed images, called RAW images. These are simply the actual data recorded by the camera sensors, and they give you some advantages, such as better correction of white balance. But GIMP does not open RAW images directly. But there are some work-arounds which we discuss in this tutorial.

                                                            Quick peek at some places in code

                                                            \n

                                                            Main.hs has our Main module definition. It was generated by Stack when we started. In the end of the main function, it calls run function, which is defined in Run.hs file. This is the place where we can see overall flow of the program in one glance.

                                                            \n
                                                            run :: RIO App ()\nrun = do\n  choice <- showMainMenu\n  case choice of\n    StarNewGame -> do\n      logDebug "New game starting..."\n      logDebug "Rolling new character..."\n      player <- liftIO $ evalRandIO rollNewCharacter\n      displayNewCharacter player\n      logDebug "Selecting starting gear..."\n      gear <- selectStartingGear $ playerGear player\n      logDebug "Preparing game..."\n      game <- liftIO $ evalRandIO $ startGame player gear\n      logDebug "Dealing first card..."\n      finishedGame <- playGame game\n      logDebug "Displaying game over..."\n      displayGameOver finishedGame\n\n    ExitGame ->\n      return ()
                                                            \n

                                                            Another interesting module is Types. Here you can find how player, items, monsters and such are represented.

                                                            \n

                                                            Third and biggest module is UserInterface, which contains functions to display game status to player and ask their input.

                                                            \n

                                                            So, what does our run function do? Lets have a look:

                                                            Word about input and output

                                                            \n

                                                            One of the features of Haskell I like is the ability to show which functions are pure (always returning same output with given set of inputs and not having any side effects). In our program, every function that returns RIO a b has access to input and output. In addition to that, it also has access to system wide configuration (which we don't use much here) and logging functions.

                                                            \n

                                                            To write on the screen, we use putStrLn and reading a user input readLine. Since they're designed to work with IO instead of RIO a b, we have to use liftIO. But all that is technical details that we won't worry now.

                                                            \n

                                                            App is our configuration. We aren't directly using it, so it's safe to ignore for now.

                                                            \n

                                                            Showing main menu

                                                            \n

                                                            showMainMenu function will print out the menu and then call mainMenuInput. mainMenuInput will read input, validate that it's either 1 or 2 and return respectively StarNewGame or ExitGame. In case user enters something else, mainMenuInput will recurse until user enters valid input.

                                                            \n
                                                            -- | Display main menu\nshowMainMenu :: RIO App MainMenuChoice\nshowMainMenu = do\n  logDebug "Displaying main menu"\n  liftIO $ putStrLn "\\n\\n"\n  liftIO $ putStrLn "Treasure Dungeon"\n  liftIO $ putStrLn "****************"\n  liftIO $ putStrLn ""\n  liftIO $ putStrLn "1.

                                                            \n

                                                            You might wonder, why mainMenuInput can keep calling itself without filling the stack? That's because Haskell doesn't use stack in the same sense as many other programming languages. Haskell compiler is also smart enough to notice that call to mainMenuInput is last operation of the mainMenuInput, there is no work to be done after the call, and thus can optimize things even more. I don't know all the dirty details how this has been implemented and how things work behind the curtains.

                                                            \n

                                                            Rolling new character

                                                            \n

                                                            player <- liftIO $ evalRandIO rollNewCharacter rolls a new character, but what exactly is going on here? rollNewChacter has following signature: rollNewCharacter :: (RandomGen g) => Rand g Player. It doesn't take any parameters and returns Rand g Player, where g implements RandomGen. So, it's Rand monad that returns Player. In order to get the result of the computation, we call evalRandIO that uses global random number generator to compute. And since it's an IO operation, we need liftIO. It's bit confusing at first, so don't worry if you don't get all the details. The main point is that we're doing computation with random numbers.

                                                            \n

                                                            Implementation is not too complex:

                                                            \n
                                                            rollNewCharacter :: (RandomGen g) => Rand g Player\nrollNewCharacter = do\n  str <- dice 3\n  dex <- dice 3\n  mind <- dice 3\n  maxHp <- dice 4\n  return $ Player\n    { playerStrength  = MkStrength str\n    , playerDexterity = MkDexterity dex\n    , playerMind      = MkMind mind\n    , playerHP        = MkHP maxHp\n    , playerMaxHP     = MkHP maxHp\n    , playerGear      = [ ]\n    }
                                                            \n

                                                            This rolls three six sided dice for each attribute and 4 for hit points. The values are then used to create Player record that is returned.

                                                            \n

                                                            dice is implemented as following:

                                                            \n
                                                            dice :: (RandomGen g) => Natural -> Rand g Natural\ndice n = do\n  rolls <- getRandomRs (1, 6)\n  let roll = sum $ take (fromIntegral n) rolls\n  return $ fromInteger roll
                                                            \n

                                                            Again, we're using Rand monad for random number generation. getRandomRs supplies us an infinite list of numbers between 1 and 6. Then we use take to some of them and sum to add them together. fromIntegral n is needed, because take doesn't operate on Natural type, but Int. I wanted to use Natural though, because that ensures that the parameter n will always be 0 or more.

                                                            \n

                                                            In closing

                                                            \n

                                                            Now we have a basic layout for our program and know how to roll a character with random stats. Next time we'll finally look into getting some gear on them. The code for the game is available at my codeberg repository.

                                                            \n

                                                            Please remember that we normally ask that shows submitted by a host be spaced out by at least two weeks - unless the queue is extremely short of shows of course!

                                                            \n

                                                            Commas between tags

                                                            \n

                                                            A number of shows in recent weeks have been arriving with tags lists missing the requested commas. Hosts are requested to use these to separate tags, otherwise it can be difficult to work out where one tag ends and the next begins. How to interpret the following list, for example:

                                                            \n
                                                            dog fish custard
                                                            \n

                                                            Does it mean: 'dog fish, custard', 'dog, fish custard' or 'dog,fish,custard'?

                                                            \n

                                                            Host names/handles or series names as tags

                                                            \n

                                                            Next, a recommendation about the host name/handle or the series name as a tag. Tags are intended to help with finding shows.

                                                            \n

                                                            We have another way of finding shows by host; the host name or handle is a link at the top of the show page which can be clicked to go to a list of all of the shows ever submitted by that host.

                                                            \n

                                                            Also, if a show is part of a series, clicking on the series title on the show page will take you to all the shows in that series.

                                                            \n

                                                            So, two tags best avoided are: the host name and the series name.

                                                            \n

                                                            Use of Explicit only covers audio

                                                            \n

                                                            Be aware that the selection made during the submission of a new show between 'Explicit' and 'Clean' only relates to the audio. Due to the world-wide distribution of shows we need to be sensitive to potential offense caused by swearwords and the like in the notes themselves. We would appreciate all HPR hosts being aware of these issues.

                                                            \n

                                                            Please do not add your own intro and outro

                                                            \n

                                                            A final reminder: it was decided via discussion on the HPR mailing list that we would automate the addition of the intro and outro to show audio. We would appreciate it if hosts did not add these themselves because work is then required to remove them before preparing the show for release.

                                                            \n

                                                            Some work has been going on behind the scenes to improve the workflow which handles incoming shows and adds them to the database.

                                                            We have added a set of state values which indicate the processing flow so that people and software can track progress.

                                                            The calendar page has been adjusted to show some of these state mnemonics in addition to the Locked and Processing indicators we have had before.

                                                            The problems reported in the last Community News have now been resolved.

                                                            Older HPR shows on archive.org, phase 2

                                                            Now that all shows from number 1 to the latest have been uploaded to the Internet Archive there are other tasks to perform.

                                                            \n

                                                            During the uploading of shows in the range 1-870 we uploaded all the audio versions: wav, ogg, mp3, etc. We also uploaded any other files such as pictures or documentation. We do this for new shows as well.

                                                            \n

                                                            The reason for this is to make self-contained shows on the Internet Archive, where previously such shows referred to the HPR server for various components.

                                                            \n

                                                            The shows that had been uploaded during 2017 in the range 871 to 2429 did not include all these files. At that point we only had the mp3 versions of the audio, and these were what were uploaded, along with the notes.

                                                            \n

                                                            During phase 1 of the upload process a method of turning the mp3 audio into all of the other formats was included, and this method is now being used to re-process shows 871 to 2429.

That means we need to use directory commands to create a structure to store our files, and to find the files we have stored there. This tutorial takes us through the various commands you can use to do this.

                                                            The Surface Pro X is a 2-in-1 detachable tablet computer developed by Microsoft. It was developed alongside and was announced on 2 October 2019 alongside the Surface Pro 7 and Surface Laptop 3.[1] Updated hardware was announced alongside Surface Laptop Go and Surface accessories on October 1, 2020[2] and September 22, 2021.[3] The device starts at $899.99 USD / £849.99.[4][5]\n

                                                            The Surface Pro X comes with a Microsoft SQ1 or SQ2 ARM processor, which the company claimed has three times the performance of an x86 MacBook Air, whilst also having a 13-hour battery life. This is due to the increased power efficiency of ARM processors compared to traditional x86 processors.[1][6][7] Microsoft has previously used ARM processors in the discontinued Surface RT and Windows Phone devices.\n

                                                            Microsoft now offers a Wifi-only version of the device as announced at their Surface Event on September 22, 2021.[8]\n

                                                            Introduction

                                                            \n

                                                            This episode was prompted by show 3542 from Beeza entitled The Worst Car I Ever Had. Here’s my story.

                                                            \n

                                                            I moved to Edinburgh in 1981, and before long bought myself a car - the first one I had owned. Before that I’d owned a series of Lambretta motor scooters and small to medium powered motorbikes. I’d been using a bicycle a lot after that.

                                                            \n

                                                            The car I bought was an oldish Peugeot 104, small, not very powerful, but it did the job. It was fine for driving around town and I used it to go and visit my parents in Norwich, England a few times, a long journey. I once drove north, up to Ullapool, a shorter drive, but it wasn’t the car for long journeys. Mostly it was used around town.

                                                            \n

                                                            As the Peugeot started to give me trouble I looked around for a replacement. I was visiting my parents and went to a car dealer in Norwich and was shown an Austin Maestro. It was newer than the Peugeot and seemed to be in good condition, so I bought it, trading in the Peugeot as I did so.

                                                            \n

                                                            The Maestro range was seen as reasonably good as far as I knew, but this one suffered from some design flaws, in my opinion.

                                                            \n

                                                            The car I bought was only a few years old and had a fairly low mileage. It was the HLE model with a 1.3 litre petrol engine. It had 4 doors and a hatch at the back giving access to a reasonable amount of luggage space (often such hatchbacks are called 5-door cars in the UK). All Maestro models had front-wheel drive, and this one had a manual gearbox. Automatic British cars were not common at that time.

                                                            \n

                                                            The Maestro had a bunch of economy features:

                                                            \n
                                                              \n
                                                            • a 4-speed gearbox with some economy gear ratios
                                                              • \n
                                                            • an econometer on the dashboard with green and red LEDs indicating how economically the car was being driven
                                                              • \n
                                                            \n

                                                            The Issues

                                                            \n

                                                            The Maestro seemed to have been designed to be driven as empty as possible. As soon as there were any passengers, or luggage, or both, the car was a nightmare to drive.

                                                            \n

                                                            There were models in the range that performed well, I think. Being passed by them on motorways and when trying to drive up any kind of hill showed this to be true. I’ve read that the standard 1.3 model was pretty good without the economy features, but I never experienced one.

                                                            \n

                                                            The problem was that the gap in gear ratios between the second and third gear was enormous, as if you’d accidentally skipped a gear. The fourth economy gear could only be resorted to on flat roads – or going downhill – or with a tail wind – or with the car completely empty.

                                                            \n

                                                            I was happy to find a link describing these problems when doing research for this show. The description of the car made me laugh, but also brought back memories of the extreme frustration I experienced with this car!

                                                            \n

                                                            So, I conclude that this particular Maestro was a failure. It might be the reason I got it at a good price; the previous owner was probably keen to get rid of it. Also the car dealer knew a sucker when he saw one, and I was that fool!

                                                            \n

                                                            I kept the car for a few years, did very few long journeys in it and eventually replaced it with a Vauxhall Astra Mark III, which was in a totally different league!

                                                            \nThis week we stop to take a moment to focus on the Who rather than the What is attacking us. In CyberSecurity, we tend to get caught up in things that happen to us, that we forget that it is actually a person attacking us. Learning more about who wants the information we have will tell us the ways they go about stealing it. This gives us information to better protect our assets and begin active threat hunting. The show is about 15 minutes long.

Math is a subset of logical thinking and not the other way around. I can think of hundreds of occupations that require logical thinking that do not require any maths. It would be difficult to argue this point as it could be argued, as most people are exposed to counting no matter what level of literacy they may have access to. So let us refer to studies with crows that shows that they do think logically - despite any math knowledge.

The main different legacy virtualisation\ntechnologies like virtual machines (VMs) and this new-fangled approach is\nthat the OS kernel remains the same across virtualisation domains, thus giving\nthe hippsters and other followers of fashion a cheaper and potentially much\nfaster solution than virtualising the kernel and surrounding hawrdware and all\nthe rest of it. Plus more details on Martin's real faith. Don't miss out on\nthis episode if you're interested in any of these...

Wildcards can let you look for files and directories without specifying the complete name, and look for items with similar names or file extensions. And file attributes are an important part of file management.

                                                              3. It will stretch a little – Less likely to rupture if water contained in PEX freezes
                                                                4. \n

                                                                    \n

                                                                    2. \n

                                                                    3. \n

                                                                    3. \n

                                                            In today's show Dave and I will read out the mail list thread we didn't cover in the Community News.

                                                            \n

                                                            Before we get to that, I wanted to inform you that we now know that the host in question was deliberately trolling HPR.

                                                            \n

                                                            I know this because they told me, and when I asked them to stop they went on to explain that they are a gadfly. I had to look that one up.

                                                            \n

                                                            Whatever they claim to be, the end effect for us is trolling.

                                                            \n

                                                            Both Josh and Myself have had some unnecessary stressful weeks for someone's idea of a joke.

                                                            \n

                                                            That said there have been some positives about this as well.

                                                            \n

                                                            Again we see the HPR community at its best in providing support and reasoned arguments.

                                                            \n

                                                            We have identified a possible loop hole in governance, that has been addressed by having a special advisory committee aka the auditor team of volunteers.

                                                            \n

                                                            And when we come up with a way of dealing with troll issues, we also get a mechanism to deal with DMCA take down requests, and other complaints.

                                                            \n

                                                            So what do we do with a troll ? Easy, just ignore them, or to put it another way \"Stay Calm and Go On\".

                                                            \n

                                                            This works well for comments but its not enough when the tactic is deliberate targeting of HPR.

                                                            \n

                                                            A lot of effort has gone into this attack:

                                                            \n
                                                              \n
                                                            • First they built trust by posting technical shows. This is a similar tactic that we see spammers use.
                                                              • \n
                                                            • Then they submitted a series of shows that would cause HPR legal issues.
                                                              • \n
                                                            • They then did not respond to questions, presumably in the hope that we would delete the shows ourselves.
                                                              • \n
                                                            \n

                                                            By moving the shows out to later in the queue we were able to avoid claims of \"censorship\", and they eventually removed the problem shows of their own accord.

                                                            \n

                                                            So what attack vector will be used next, and how will we deal with it ?

                                                            \n

                                                            I have no idea, but how to deal with it is also not so easy. We'll have to cross that bridge when we come to it.

                                                            \n

                                                            We do however need to tackle the risky situation of having problem content available on the website.

                                                            \n

                                                            So I suggest that we continue to post the shows as normal, if we get a complaint then the Janitors will contact the host as normal.

                                                            \n

                                                            Should they be unavailable, uncooperative, or disagree, then the Janitors can either move the show to the backup queue, or hide it depending on the severity of the complaint.

                                                            \n

                                                            In all cases we'll keep the special advisory committee aka the auditor team of volunteers in the loop to make sure all is above board.

                                                            \n

                                                            The community can then decide on the best course of action.

                                                            \n

                                                            So therefore I would like to propose the following changes to our policies.

                                                            \n

YouTube has been something of a lifeline in the past years, helping me find stuff I actually want to watch, which (mostly) doesn’t have all the fake crap that’s on TV. I must say though, that I loathe and detest the apparent trend towards #shorts - I really don’t see the point of them!

We seek a stronger, fuller democracy – in our politics and culture as well as in our economy - based on workers’ equal collaboration and shared leadership inside enterprises and throughout society.

The seals find these things, such as spools or bundles of fishing line, and tend to play with them, and eventually the loop or spool gets stuck around their neck, which can cut them badly and eventually kill them.

                                                            This will be a short episode, but a very important one.

                                                            \n

                                                            Since we have people from around the world who listen to Hacker Public Radio, I cannot begin to speculate what your local building codes allow or prohibit. In the majority of states within the United States of America, a property owner can perform plumbing maintenance on their own residence. Otherwise you need to be a licensed plumber. That may not be true for all states, and there can be inspections required and sometimes even fines for code violations.

                                                            \n

                                                            Rules also vary for where PEX can be installed, how and how frequently it must be supported, and whether the work must be inspected or whether it requires a permit.

                                                            \n

                                                            The point of this section is to remind you to do your research to find out what the rules are in your specific region, and then be sure to follow them. When in doubt, consult a licensed plumber in your area.

                                                            Guest Host #2 provides tips and examples on how to use variables safely and politely provide default values. One example of assigning a default value is:

                                                            \n
                                                            foo=${foo:-"blah"}\n

                                                            Carl then closes out with the : (colon) shell builtin and provides a variation on the above default value:

                                                            \n

Picking up from the last episode, we are now delving in to the security measures we can implement to make ourselves a less attractive for Evil Steve. After implementing 2FA, we should now be setting up and using a password manager. Then we look for and changed passwords involved in known breaches (haveibeenpwned - link in show notes). The show is approximately 19 minutes long.

                                                            SimpleSSHD is an SSH2 server based on dropbear that supports scp, sftp, and rsync. It only supports public-key based authentication (no password/interactive auth except for bootstrapping). It does not use root, which means it must listen on a port over 1024 (defaults to port 2222).

Listen to the show! :-) . A cautious warning: This episode contains strong philosophical / political views, language and insights which may change your views on messaging systems in general and Kafka in particular. Two hints: Chris shares his view on what a database *really* is and Kris Jenkins tries hard to convince our two aging heroes that he's the man for the job (teaser: he decided to stay at his current position as a dev advocate at Confluent after all). Plus: More on love, death and robots. Interested in the details? Then don't miss this show! \n

Why, you may ask, given the fact that this podcast has only been in existence\nfor roughly over two years, are we reviewing this history? The answer - of course - is\nstraight forward: by sheer coincidence our two heroes got hold of a future episode\nwhich traveled back in time from the future. If you ever wondered about time-travel,\nthe paradoxes associated with this and what the next twenty years have in store not\njust from a Linux Inlaws perspective, this episode is for you.

He apparently died in November 2021 as a consequence of COVID-19. His family did not know who to contact in the wider community, so this news only became apparent recently.

                                                            My original intent was to create markdown files that could be feed into an existing static site generator, something like Hugo or Jekyll.

                                                            \n

                                                            I started with markdown but had to add too much html.

                                                            UNIX, Linux, and BSD

                                                            Linux was created by PC users attempting to use mainframe UNIX. BSD was created by mainframe UNIX users attempting to use a PC.

                                                            BSD is what I like to call a “Pedigree UNIX”, meaning that it is a pure blooded descendant of AT&T UNIX. Although all of the original AT&T code has been re-written so a permissive license, the heritage persists.

                                                            \n

                                                            In contrast to Linux (which shares no original Bell Labs code), BSD was originally all Labs code.

                                                            \n

                                                            BSD in the wild

                                                            \n

                                                            BSD style licensing is quite simple to understand compared to the tome that is the GPL. Interpreting it usually goes something like follows:

                                                            \n

                                                            Do whatever the hell you want with this code, just don’t blame me when it breaks something and don’t claim you wrote it

                                                            \n

                                                            Permissive licensing means that various companies can put lipstick on the UNIX pig and falsely assert that it’s anything other than lipstick on the UNIX pig. Not that UNIX is a pig, but you cannot disguise a pig with lipstick. Those burdened with the gift of sight and knowledge can spot a UNIX system quite easily.

                                                            Most Linux enthusiasts are missionaries. They are generally helpful and seek to guide the computing neophyte into the inner circle of FSF initiates.

                                                            \n

                                                            The BSD guys tend to be like hermits. They don’t care if you use their code, they only care that the code works for them. When you ask for help, a typical response will be “did you even read the error logs?” or “did you even RTFM? What about supplemental documentation? We didn’t write TFM just so you could go online and ask something clearly documented in TFM.”

                                                            \n

                                                            Not all BSD guys are bitter, but you really should consult available resources before asking questions

                                                            Forking vs distros

                                                            \n

                                                            In Linux land, all the distros are basically the same with varying coats of paint. We call these distributions because all “implementations” of linux are nearly identical code bases built with varying compile time options.

                                                            In BSD land, distros don’t exist. Free/Net/Open are entirely independent and don’t share a common upstream. They are forks of primordial BSD that run separate kernels, separate userlands, etc. Although code is shared amongst each other, a statically linked binary can’t simply be dumped from one to another and still run as it would in Linux land.

                                                            Selecting a FreeBSD fork that comes with a desktop is your goto. The currently maintained desktop distros are HelloSystems, GhostBSD, NomadBSD, and MidnightBSD.

                                                            I want a viable desktop operating system

                                                            \n

                                                            FreeBSD with a non-GNOME DE is fairly reliable. I’ve had success with KDE, XFCE, and various tiling window managers. GNOME is too reliant on systemd so the port is janky.

                                                            I want something to learn by example with

                                                            \n

                                                            OpenBSD is a great learning platform. The source code for userland utils is simple, short, and generally free from OS specific function calls. RTFM goes by the wayside when you easily RTFSC.

                                                            \n

                                                            OpenBSD eliminates many foot shooting scenarios by being a thorn in the side of the user who wants to do stupid things

                                                            \n

                                                            OpenBSD runs on a lot of architectures: i386, amd64, arm64, arm7, alpha, sparc64, risc64, ppc64, etc. The devs self-host these ports (ie build the release on a physical processor instead of cross compiling). This means that the alpha port is actually built on a VAX machine, the sparc port is actually built on a sparc machine, etc.

You will suffer less if you can find a pure Intel machine. The biggest things to look for are an intel CPU, intel wireless chipset, intel integrated graphics, and an intel sticker. Vpro vs no vpro doesn’t seem to make a difference in my anecdotal experience.

                                                            1. Think about a small problem you want to solve with code.

Yes, the platform that the Inlaws have been using since the very inception of this rapidly growing FLOSS podcast content. Wondering what the heck this episode is all about, why exactly Martin and Chris are talking about this now and the importance of statistics, lies and damned lies? Then just listen to this episode. You may also find out the difference between mere caching and content syndication. Never mind HPR's inner workings.

                                                            In this episode, I describe my ongoing attempt to develop a static site generator for the HPR website. As a search through the community mailing list will reveal, the idea for moving the HPR website has been rattling around for a few years. I have been interested in helping out with the website for a while, so when the latest round of discussion occurred I decided to give it a whirl.

                                                            \n

                                                            While I have read about various static site generators over the years, the only one I had any experience with was Template-Toolkit (TT2) when helping Ken Fallon and Dave Morriss develop the Free Culture Podcasts webpage. It is the tool Dave uses for various projects. Since they are the janitors for HPR, I figured a website generator based on the TT2 would be something relatively painless enough for them to use, and update when needed.

                                                            The code for this generator is hosted at https://repo.anhonesthost.net/rho_n/hpr_generator. The generator is written in Perl and generates the pages using TT2 templates.

Billions of unwanted calls to American consumers are being blocked each year.

Example: although Linux and GNU are overly complicated, they pass the duck test for being a UNIX. Pedigree or not, you know a nix when you see one.

                                                            UNIX is a multiuser time sharing networked operating system, running as an always online service. A UNIX system is a single mainframe computer running an operating system designed for multiple users to access concurrently over the network, equally (depending on implementation) sharing resources amongst the active users.

                                                            \n

                                                            In a traditional network setup, there is one mainframe UNIX machine with multiple dumb terminals connected to it over the network. None of the users touch the mainframe physically. Instead, they interact with it exclusively through their own dumb terms. These dumb terminals have minimal or no computing power of their own because all of the actual computation takes place on the mainframe. Built in networking is a given.

                                                            As for the actual software running on the mainframe, it's quite simple to visualize. A Unix system is a flexible but organized stack of concepts, each depending on the concept below, all working together for the sole purpose of enabling the end user to play video games and watch videos online.

                                                                   / user applications \\\n      /       shells        \\\n     /        daemons        \\\n    /       file systems      \\\n   /        kmods/drivers      \\\n  /           syscalls          \\\n /             kernel            \\\n/             hardware            \\\n
                                                            \n

                                                            In order to fully explain why UNIX is sublime, I will start from the bottom and work my way upward. Before I discuss the shell, I will explain the multiuser aspects of the system. Then, after a long arduous journey of verbosity, explain how to actually use the thing.

                                                            \n

                                                            Kernel

                                                            \n

                                                            The kernel is something the user rarely interacts with. It abstracts all the hard parts away from the user. No more poking random memory addresses to load a program from tape.

                                                            \n

                                                            Multitasking

                                                            \n

                                                            In order to support multiple users, resource sharing was implemented. When a user's process requests CPU time, it's put into a rotational queue along with the other requests for CPU time. Round robin style concurrency is one of the easiest to implement but most modern systems use a weighted model that prioritizes processes owned by specific users. Memory and disk space are typically assigned hard limits to prevent system crashes. \"Ask your sysadmin if you need more resources.\"

                                                            \n

                                                            Virtual Memory

                                                            \n

                                                            Abstracting memory management from users is almost necessary in a multitasking system. The kernel must be the arbiter of all. The most interesting thing about virtual memory is that it doesn't actually need to be a RAM stick, but can be a swap partition on a disk or even a remote cloud provider if you've actually lost your mind. This type of flexibility improves system stability. Instead of a kernel panic when memory runs out, the kernel can de-prioritize nonessential or idle processes by sending them to swap space.

                                                            \n

                                                            Paged Memory (logical memory)

                                                            \n

                                                            No more fragmented memories! The kernel maintains a page table that maps logical locations to physical locations. Instead one continuous chunk of memory, the kernel divides memory into small sections called \"pages\". When allocating memory, the kernel might not give a process continuous pages. The advantage of a paged memory scheme further enables multiuser computing. Example: When you have a large program like a web browser open, the pages that contains the unfocused tabs can be swapped out to disk without stalling the entire browser.

                                                            \n

                                                            Programming Interface pt. 0 (syscalls, kmods, drivers)

                                                            \n

                                                            When a process requests a resource, it sends a syscall to the kernel. The kernel then responds to the system call. This allows for privilege separation. Does your web browser need direct access to all memory? What about all files? Do we even want to write assembly every time we want to access a file? Syscalls are dual purpose: abstraction and security.

                                                            \n

                                                            Kernel modules are dynamic \"extensions\" that give the kernel new features (typically hardware support). The ability to dynamically load/unload modules as hardware changes increases uptime because it means a new kernel doesn't need to be compiled, installed, and booted into every time we plug in a different peripheral.

                                                            \n

                                                            Filesystem

                                                            \n

                                                            Hierarchical structure

                                                            \n

                                                            A UNIX filesystem is hierarchical. Each directory contains files or other directories, each with a specific purpose. This type of organization makes it very easy to navigate and manage a system. Each child directory inherits ownership and permissions unless otherwise specified (see Access Control).

                                                            \n

                                                            In order to visualize this, I imagine a tree-like structure descending from the root directory, /. The tree(1) program shows this type of hierarchy.

                                                            \n

                                                            Virtual Filesystems (logical filesystem)

                                                            \n

                                                            The idea behind virtual filesystems is, again, abstraction. Using the concept of a virtual file system, multiple disks can be presented to the user and programmer as a single unified filesystem. This means mounted local disks, NFS shares, and even the contents of a CDROM are presented as if the files contained therein are \"just on the big hard drive\".

                                                            \n

                                                            Additionally, using bind mounts, a directory can be mounted onto another directory as if it were just another filesystem.

                                                            \n

                                                            The final interesting thing about virtual filesystems is the concept of a ramdisk: mounting a section of memory so that it can be used as if it was an ordinary directory. <--Shoot foot here.

                                                            \n

                                                            Everything is a file

                                                            \n

                                                            Well, almost everything is presented as if it were a file. This greatly simplifies programming.

                                                            \n

                                                            Prime example: /dev/urandom is a random entropy generator presented as a file, making it very simple for a programmer to implement seeded RNG in a program.

                                                            \n

                                                            Another example: The kernel translates mouse input into a data stream that can be opened as a file. The programmer only needs to read from /dev/mouse0 instead of writing hundreds of mouse drivers for a clicky GUI.

                                                            \n

                                                            Exercise 1: Try running this command then wiggling your mouse:

                                                            \n
                                                            # Linux\n$ sudo cat /dev/input/mouse0\n\n# FreeBSD\n$ sudo cat /dev/sysmouse\n
                                                            \n

                                                            Yet another example: the TTY is just a file. You can even print it to a text file using setterm(1) on Linux.

                                                            \n

                                                            Exercise 2:

                                                            \n
                                                            [user@fedora ~]$ sudo setterm --dump 3\n[user@fedora ~]$ cat screen.dump\n\nFedora Linux 36 (Workstation Edition)\nKernel 5.18.5-200.fc36.x86_64 on an x86_64 (tty3)\n\nfedora login: root\nPassword:\nLast login: Sat Jul 30 14:34:20 on tty3\n[root@fedora ~]# /opt/pfetch/pfetch\n        ,'''''.   root@fedora\n       |   ,.  |  os     Fedora Linux 36 (Workstation Edition)\n       |  |  '_'  host   XXXXXXXXXX ThinkPad T490\n  ,....|  |..     kernel 5.18.5-200.fc36.x86_64\n.'  ,_;|   ..'    uptime 20d 22h 40m\n|  |   |  |       pkgs   3910\n|  ',_,'  |       memory 6522M / 15521M\n '.     ,'\n   '''''\n\n[root@fedora ~]#\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n[user@fedora ~]$\n
                                                            \n

                                                            Links

                                                            \n

                                                            Yet another way of \"mounting\" a file or directory to another file or directory is linking. There are two types of links: hard links and symbolic links.

                                                            \n

                                                            On UNIX, files are indexed by inodes (index nodes). Using links, we can make \"shortcuts\" to files.

                                                            \n

                                                            Hard linking adds a \"new index\" to a file. They share an inode. If the original file is removed, the file persists in storage because the secondary file created by a hard link still exists. Think \"different name, same file\"

                                                            \n

                                                            Symlinks are like pointers. A symlink points to the original file instead of the inode. If you remove the original file, the symlink breaks because it points to a file that points to an inode rather than simply pointing to an inode.

                                                            \n

                                                            Using links, we can make files more convenient to access as if we are \"copying\" files without actually copying files.

                                                            \n

                                                            Filename extensions

                                                            \n

                                                            On a UNIX system, file extensions are arbitrary. UNIX determines file type by reading the file headers. The file tells you exactly what type of file it is (just read it). The entire system does not break when a file extension doesn't match the expected contents of the file.

                                                            \n

                                                            Extensions only matter when you wilfully associate with the microsoft users leaving issues on your software repos. \"Not my OS, not my issue, it's open source so fork it if you don't like it\"

                                                            \n

                                                            Multiuser (timesharing)

                                                            \n

                                                            See also: Multitasking.

                                                            Exercise 3: attempt to use Windows like a multiuser operating system and get back to me when you have realized that any and all claims made by microsoft about how their \"multi user enterprise system\" is in any way capable of competing with a genuine multi-user UNIX system are false advertising.

                                                            \n

                                                            Users, Groups

                                                            \n

                                                            A multiuser system needs a way to manage users and categorize them for access control purposes. Every user has a single user account and belongs to 0 or more groups. Sorting users into groups at the time of account creation makes is significantly easier than granting/revoking permissions user-by-user. Additionally, using something like rctl(8) on FreeBSD allows a systems administrator to allocate resources to specific users, groups, or login classes (like groups).

                                                            \n

                                                            Daemons (services)

                                                            \n

                                                            On a UNIX system, every process is owned by a user. In the case of a service, the process is owned by a daemon account. Daemon accounts have limited permissions and make it possible to run persistent services as a non-root user.

                                                            \n

                                                            Since UNIX was designed to be a multiuser system, access control is required. We know about users, we know about groups, but what about permissions?

                                                            \n

                                                            There are three types of operations that can be done to a file: read, write, and execute. Who can the admin grant these permissions to? The Owner, the Group, and the Other (all). This type of access control is called discretionary access control because the owner of the file can modify files at their own discretion.

                                                            Programming interface Pt. 1 (data streams)

                                                            \n

                                                            All UNIX utilities worth using use 3 data streams:

                                                            \n

                                                                \n

                                                              • \n
                                                            • stdout\n
                                                                \n
                                                              • print to it the same way you print to a terminal (file)
                                                                • \n

                                                                \n
                                                              • print to it the same way print to a file, read from it the same way you read from a file
                                                                • \n

                                                            Shell

                                                            \n

                                                            The shell is how a user actually interacts with a UNIX system. It's a familiar interface that allows a human user to interact with a computer using real human language.

                                                            \n

                                                            Explicitly telling the computer to do is infinitely less agonizing than dealing with a computer that tries to do what it thinks you want it to do by interpreting input from a poorly designed, overly engineered interface.

                                                            \n

                                                            The shell, in addition to being an interactive interface, is also scriptable. Although math is a struggle, shell scripting is a fairly simple way of automating tasks. Taping together interoperable commands you already know makes everything easier. My favorite aspect about writing POSIX shell scripts is knowing that shell is a strongly, statically typed language where the only datatype is string.

                                                            \n

                                                            Problem that are difficult or messy to solve in shell usually mean it's time to write another small C program for your specific needs. Adding the new program into the shell pipeline is trivial.

                                                            \n

                                                            Pipes

                                                            \n

                                                            Pipes, the concept that makes UNIX so scriptable. A shell utility that follows the UNIX philosophy will have a non-captive interface, write uncluttered data to stdout, read from stdin, and error to stderr. The | pipe character instructs programs to send their stdout to the next stdin in the pipeline instead of printing to the terminal.

                                                            \n

                                                            All standard command line utilities are interoperable and can be easily attached like building blocks. \"Meta programming\" has never been easier.

                                                            \n

                                                            Pipes make it so that every UNIX program is essentially a filter. Sure, you could just use awk, but I prefer shell.

                                                            UNIX is a non-simple modular operating system designed for 1970s big iron mainframes but we love it too much to let it go. Compared to minimal hobbyist operating systems, UNIX is BIG. Compared to commercial operating systems, free UNIX is small. Maybe slightly more than minimum viable but the papercuts are mild enough to forgive.

                                                            \nA MUD ( originally Multi-User Dungeon, with later variants Multi-User Dimension and Multi-User Domain), is a multiplayer real-time virtual world, usually text-based. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, non-player characters, and actions performed in the virtual world. Players typically interact with each other and the world by typing commands that resemble a natural language.

                                                            The boys at bell labs decide UNIX wasn't good enough so they decided to build something better: a distributed multiuser operating system composed of many machines. Many of the same ideas behind UNIX were pushed to absurd extremes. The idea that \"everything is a file\" is made blatantly apparent to everyone and sometimes, in my opinion, can feel 'overly-abstracted'. Additionally, the concept of private namespaces makes the concept of virtual filesystems seem like 'baby's first filesystem abstraction'.

                                                            Just like UNIX, 9 started as a research operating system. Both are enjoyed by hobbyists, both are interesting ways of using a computer, both have a lot of fun in store. But the systems do diverge in one major aspect: UNIX is mainstream and 9 is still a research operating system. Plan 9 is currently distributed under the MIT license.

                                                            Plan 9 is a distributed computing environment assembled from separate machines acting as terminals, CPU servers, and file servers. A user works at a terminal, running a window system on a raster display. Some windows are connected to CPU servers; the intent is that heavy computing should be done in those windows but it is also possible to compute on the terminal. A separate file server provides file storage for terminals and CPU servers alike.

                                                            The goal of 9 was to build a distributed operating system that expands upon Unixy ideas, not to build something that's backwards compatible. \"We want to improve UNIX\" is mutually exclusive to \"we want to port UNIX to this wacky new kernel\". UNIX programs (and behemoths like FireFox) are difficult^impossible to port to 9 because of this design decision.

                                                            \n

                                                            Since 9 was designed to be a distributed operating system, many of the internals are oriented towards networking. On a single system installation, all three of the components that make a 9 network are working together in a client-server model. The filesystem is presented as a service, the CPU is presented as a service, and the terminal is presented as a service. This type of \"abstraction from the physical hardware\" makes it difficult to succinctly describe and explain 9.

                                                            \n

                                                            If you think about 9 as a heterogeneous network of machines the ideas start to make sense. If you think about 9 as a self-contained single-machine operating system the ideas only become more confusing.

                                                            \n

                                                            One thing that has helped me wrap my head around the client/server idea is actually thinking less. When running a MySQL server in a LAMP stack, the database server and client are running on the same machine. When writing a program, you instruct the client to access the database located at the address localhost. Despite the design intention to run the database as a separate machine, loopback device hacks ensue. The idea of client/server permeates 9.

                                                            The filesystem? Presented as a server regardless of what physical machine it's located on. The CPU? Presented as a server regardless of what physical machine it's located on. The terminal? Presented as a server regardless of the physical machine it's located on.

                                                            9p is a networking protocol that makes this client/server model possible. Internally, the filesystem is served to the client over 9p. Many applications make use of 9p, including text editors, windowing systems, plumber, etc. In UNIX, everything is a file. In 9, everything is a filesystem accessed via 9p.

                                                            The most important aspect of 9: namespaces.

                                                            \n

                                                            Namespaces have caused me much confusion until recently. In 9, each process constructs a unique view of the filesystem. The phrase that gets stuck in my head is \"a private namespace is a per-process view of the filesystem\". The easiest way to think about namespaces is to think about a \"virtual directory\". Unix has \"virtual filesystems\", 9 has \"virtual directories\".

                                                            \n

                                                            The concept of namespaces allows a user to pull resources from all over the network and present them as \"a single local filesystem\" with absolute disregard for where these resources are actually coming from. In order to construct a namespace, union directories are used. A union directory is a directory made of several directories bound to the same directory. This concept is similar to a bind mount on UNIX.

                                                            \n

                                                            The kernel keeps separate mount table for each process. Using namespaces, a user or admin can create more secure isolated environments (similar to a chroot).

                                                            \n

                                                            Processes and their children are grouped together so that inheritance of the namespace occurs. These process groups can be customized.

                                                            The 'per-process namespace' concept can be confusing to UNIX users at first, especially when binding (ie mounting) resources. When I first started using 9 I was very confused when I bound something in one terminal, switched to another, then became disoriented as the thing I just bound seemingly stopped existing. My big example is mounting the boot partition or a filesystem over ssh:

                                                            \n
                                                            # In this window, I have bound the boot partition.\n# It behaves expectedly.\nterm% 9fs 9fat\nterm% lc /n\n9/      9fat/   other/  ssh/\nterm% lc /n/9fat\n9bootfat        9pc64           oldplan9.ini    plan9.ini\n9pc             efi/            pbs.bak\nterm%\n
                                                            \n
                                                            # In this other window, the boot partition doesn't seem to be mounted.\n# This causes much confusion for the end user.\nterm% lc /n\n9/      9fat/   other/  ssh/\nterm% lc /n/9fat\nterm%\n
                                                            \n

                                                            Files

                                                            \n

                                                            The second most important aspect of 9: \"Everything is a file\" taken to absurdist absolutes. The kernel presents hardware devices as files bound to /dev. Within the namespace, devices are just files. Outside the namespace, devices are named with a leading # to help distinguish between pseudo-files and devices. These physical devices are bound to /dev/ and presented as files for easy administration, access, and programming. Presenting everything as a file accessible via 9p greatly reduces the total number of system calls.

                                                            Continuing with the idea that \"everything is a filesystem\", processes can offer services to other processes by placing virtual files into other processes' namespaces. File I/O on this special virtual file becomes interprocess communication. This is similar to a UNIX socket but significantly less difficult to program against because all of the hard parts have been abstracted: it's just simple file I/O.

                                                            \n

                                                            The /proc filesystem presents processes as a files in a filesystem. This makes writing programs that manage process extremely easy by reducing the total number of system calls to simple file I/O. The /proc filesystem allows users to manage processes using standard command line utilities like cat(1) and ls(1).

                                                            Just like UNIX, 9 was designed with portability in mind. 9 is written in a strange dialect of ANSI C which means it's portable. Although the system is self hosting, images are rarely built on a self hosting environment. Instead, the end user will download a generic amd64 or i386 image, cross compile for the obscure target architecture, wrap it up in an install image, then burn that image to an install disk. After installation, it is generally a good idea to recompile the entire operating system so that your copy is self-hosted.

The one I use is cwfs64x(4). cwfs is a strange filesystem. Every night, it makes a dump of the filesystem. You can access these dumps by running:

In the modern era, we have a WORM partition. The worm partition stores data forever so it will eventually get full and need cleaning. It is possible to run without a WORM but it's a bad idea. Built in version control.

I run 9front on a Thinkpad x220 and it seems to just work. Some people run it on a Raspi but I'm not sure why. It works quite well with KVM and QEMU if you're an OS tourist. I see no reason to add a dmesg because it will either work or it won't.

Some people have said that the 9 GUI looks similar to a smalltalk machine but I think it's just the only good stacking window manager. A three button mouse is necessary for using 9front. Shift-rightclick emulates middle click.

                                                            Rio is the Plan 9 windowing system. It's the successor to 8½ window manager. Rio is lightweight compared to X11 because access to graphical hardware is built into the kernel and using files+namespaces to access input devices.

                                                            \n

                                                            The most brief way of explaining rio is to think of it as a rectangle multiplexer, where each rectangle is served a file interface (9p). Although rectangles might seem counterintuitive at first, thinking less hard makes it easier to use. I still have difficulty efficiently using a mouse-centric interface after using terminal interfaces almost exclusively for many years. I dislike the windows way of using a mouse but the 9 way seems to make quite a lot of sense when I \"think less hard\" and allow the intuition to take control.

                                                            \n

                                                            The argument for mouse-centric computing and text editing is that it's faster. Of course, the average vim user is editing text faster than the speed of thought but most people aren't the average vim user. Instead, they only know how to use arrow keys to move a cursor. Without memorizing hundreds of vim bindings (and forgetting the names and birth dates of your family members in the process), obviously a mouse is faster.

                                                            Mouse controls are confusing at first because they follow the \"click and hold, hover to option, release\" to select an option. They look something like follows:

Color themes like Tango, Linux Console, Solarized, all of KDE, and WIndows XP are very obvious but not in a good way. Bright colors are subtly distracting and make it difficult to concentrate. When I'm configuring a UNIX system with dwm, I borrow Rio's color theme because it's an anti-theme. Give it time. It's charming in it's own way. Modifying the source code for rio allows for custom color themes. It's possible but you will be laughed at. Setting a wallpaper is also possible but I don't do this because my windows are always covering the dull gray background.

Standard UNIX shell concepts like pipes, file redirects, && and ||, etc. Scripting is not POSIX-like at all so reading the man page and various scripts written in rc is the only way to learn.

                                                            There are three primary ways of editing text on 9: ed(1), sam(1), and acme(1). There is no vi aside from the MIPS emulator, there is no emacs except for a man page explaining why there is no emacs.

                                                            I have primarily used acme in the past, but sam is a much better editor.

                                                            \n

                                                            sam is a lot like a graphical version of ed. I still need to learn ed because it's the standard editor. Some of the standard vi commands are available and regex works. I like sam quite a lot but it seems to corrupt files when the system crashes.

                                                            acme is a window manager, file browser, terminal emulator, and email client that some people use as a text editor. The coolest part about acme is the ability to write arbitrary editor and system commands in the menu bar, highlight them, then middle click to execute those commands.

Prime example: the /g/entoomen found a path traversal vulnerability in the 9front httpd server, then leveraged that vuln to exploit a vuln in the authentication system. Not that the boys back home did anything malicious with this bug . . . but the ability to pwn a system by sending cleverly crafted GET requests should tell you enough about the current state of security in 9.

Lots of tiny programs to write, not much interest in writing lots of tiny program. There is a general attitude among 9 users that \"9 is unique\" porting POSIX libs to 9 would ruin the appeal. I almost think I agree with this sentiment.

Notice how the 6 persists as the prefix/suffix to help developers remember which architecture this specific program is written for. Instead of unspecific object files with a .o suffix, the object file's suffix is actually representative of what types of opcodes the file contains. Similarly, after linking, the 6. prefix tells us that the binary is for an amd64 processor.

                                                            Why do people use 9 if it's so bad?

                                                            \n

                                                            I can't be sure about all other ~20 Plan 9 fans in the world, but for myself, it's purely out of a genuine curiosity and love for computing. My motivation for learning obscure, unnecessary, and quite frankly boring things related to computers is that it brings me some sense of satisfaction/accomplishment/enjoyment. Linux stopped being fun for me when I came to the realization that all distributions are fundamentally the same. I started exploring the BSD world only to realize that all UNIX-like operating systems are fundamentally the same. Although BSD remains a store of fun for me, I occasionally feel burned out on UNIX even if it's an abstract idea/experience/codebase I cherish.

                                                            \n

                                                            When I sit down at a computer my goal is always to discover something new, learn a new concept, explore alternative paradigms, and, most of all, to have fun in the process.

                                                            \n

                                                            For most people, 9 is a tourist experience. For me, it's the final frontier. Although I have yet to learn as much about 9 as I have about UNIX, every time I swap hard drives and boot into 9 I feel a sense of coming home. Sometimes I think I am wilfully resisting becoming a 9 expert because it will result in me struggling to find the next non-bad OS paradigm to explore.

                                                            \n

                                                            And when I think about \"using a computer\", what do I really do on the computer? I learn about it, learn about the software running on it, and proceed to write about it so that I can reinforce the ideas in a Feynman-esque way. I'm not really providing a real tangible value to the world because it's purely a \"hey, here's the things I learned the hard way so you don't have to\".

Then we move in to a discussion about the fallacy of stupid users with some great stories of stupid things done by those of us who really should know better. The moral of the story, is that we are all human and nothing will ever change that. Instead, we need to be prepared for when humans are human.

Although power management allows companies and individuals to cut power usage costs, it presents a problem for IT departments especially in being able to quickly and efficiently remotely manage PC's, especially during off-hours operation when those PC's are most likely to be in a suspended or standby state, assuming power management features are enabled.

                                                            Wait, the passwords for werc are stored in plain text? Let's log in

                                                            \n
                                                            [root@localhost]# firefox http://cirno/_users/login\n
                                                            \n

                                                            Now let's see if any of the werc users are also system users:

                                                            \n
                                                            # let's enumerate users\n[root@localhost]# curl http://cirno/..%2f..%2f..%2f..%2f..%2f..%2f/adm/users\n-1:adm:adm:glenda,pwn\n0:none::\n1:tor:tor:\n2:glenda:glenda:\n3:pwn:pwn:\n10000:sys::glenda,pwn\n10001:map:map:\n10002:doc::\n10003:upas:upas:glenda,pwn\n10004:font::\n10005:bootes:bootes:\n
                                                            \n

                                                            Let's hope that no one is re-using credentials. Let's check just to be sure

                                                            \n
                                                            $ PASS=supersecret /opt/drawterm -u pwn -h cirno -a cirno -G\ncpu% cat /env/sysname\ncirno\ncpu%\n
                                                            \n

                                                            This is what happens when you have path traversal vulnerabilities, an authentication vulnerability in your CMS, and share login/passwords

                                                            \n

                                                            How the static-or-cgi handler works

                                                            \n

                                                            rc-httpd calls various handler scripts that decide what to do with requests. In the example configuration for werc, rc-httpd is instructed to call the static-or-cgi script.

                                                            \n

                                                            I will compile these archaic rc scripts into pseudo code for the listener.

                                                            \n

                                                            The static-or-cgi handler (the handler specified in the httpd config) is simple:

                                                            \n
                                                            #!/bin/rc\ncgiargs=$*\n\nfn error{\n    if(~ $1 404)\n        exec cgi $cgiargs\n    if not\n        $rc_httpd_dir/handlers/error $1\n}\n\nif(~ $location */)\n    exec cgi $cgiargs\nif not\n    exec serve-static\n
                                                            \n
                                                              \n
                                                            1. If the requested file exists, call the cgi handler and pass it arguments.
                                                              2. \n
                                                            2. If the requested file does not exist, call the serve-static handler.
                                                              3. \n
                                                            \n

                                                            How the serve-static handler works

                                                            \n

                                                            The problem lies in the serve-static handler:

                                                            \n

                                                            \n
                                                              \n
                                                            1. encode the full file path into a url
                                                              2. \n
                                                            2. if the url points to a file outside of '*/', the document root, error 503
                                                              3. \n
                                                            3. if the url is broken, exit
                                                              4. \n
                                                            4. if the url points to a file that neither exists nor is readable, error 503
                                                              5. \n
                                                            5. if you haven't exited by now, serve the file
                                                              6. \n
                                                            \n

                                                            The problem is no sanitization. The script checks for files in the current directory BUT NOT BEFORE ENCODING THE URL STRING.

                                                            \n

                                                            The urlencode command works by decoding encoded characters.

                                                            \n
                                                            cpu% echo 'http://cirno/..%2f' | urlencode -d\nhttp://cirno/../\n
                                                            \n

                                                            Does ../ exist in */ ? the answer is yes.

                                                            \n

                                                            .. is a directory contained inside of */

                                                            \n

                                                            */../ is the current working directory.

                                                            \n

                                                            How they fixed it

                                                            \n

                                                            Adding a sanitizer. By comparing the encoded url against an actual hypothetical file path and exiting if there is a mismatch, all %2f funny business is avoided.

                                                            \n
                                                            \n

                                                            Other (optional) bad config options in werc

                                                            \n

                                                            rc-httpd aside, a bad werc config can still lead to website defacement if your non rc-httpd webserver has a path traversal vulnerability.

                                                            \n

                                                            Additionally I have modified the DAC for /sys/www to allow werc, a child process of rc-httpd to write to disk. rc-httpd runs as the none user so it's not typically allowed to write to disk unless explicitly permitted. I do not allow this on my 9 webserver because it's the worst idea in the history of all time ever.

                                                            \n

                                                            I enabled the dirdir and blagh modules as if I were the type of admin who does a chmod -R 777 /var/www/htdocs because that's what the wordpress installation guide told me to do so I could have a cool and easy way to modify my website from the browser.

                                                            \n

                                                            Let's pretend that I'm not the admin of this system and scrape the werc config just to see if the hypothetical badmin has these modules enabled.

                                                            \n

                                                            Hmmm, looks like these modules are enabled so we can assume that httpd is allowed to write to disk. Let's modify cirno/index.md to warn the admin. As a funny joke. Totally not a crime under the Computer Fraud and Abuse Act. Totally not an inappropriate way to warn admins about a vulnerability.

                                                            Luckily enough, the webserver runs as the none user with it's own namespace.

                                                            The major difference is that the hostowner (equivalent to root user) has a lot more things bound to his namespace:

                                                            An argument could be maid that the rc-httpd vulnerability was \"not a bug\" because \"namespaces are supposed to segregate the system\".

                                                            \n

                                                            I disagree on this point. Namespaces are good and all but security is a multi-layer thing. Relying on a single security feature to save your system means relying on a single point of failure. Chroot escapes, namespace escapes, container escapes, and VM escapes are all things we need to be thinking about when writing software that touches the internet. Although unlikely, getting pwnd in spite of these security methods is still possible; all user input is dangerous and all user input that becomes remote code execution always results in privilege escalation no matter how secure you think your operating system is. Each additional layer of security makes it harder for attackers to get into the system.

                                                            \n

                                                            For example, when I write PHP applications, I consider things in this order:

                                                            \n
                                                              \n
                                                            1. don't pass unnecessary resources into the document root via symlinks, bind mounts, etc.
                                                              2. \n
                                                            2. never ever use system() in a context where user input can ever be passed to the function in order to avoid shell escapes
                                                              3. \n
                                                            3. sanitize all user input depending on context. Ex: if the PHP program is directly referencing files, make a whitelist and compare requests to this whitelist. If the PHP process is writing to a database, use prepared statements.
                                                              4. \n
                                                            4. fire up a kali linux vm and beat the test server half to death
                                                              5. \n
                                                            5. iterate upon my ignorance
                                                              6. \n
                                                            6. doubly verify DAC just to be sure
                                                              7. \n
                                                            7. re-check daemon configs to make sure I'm not doing anything stupid
                                                              8. \n
                                                            8. FINALLY: rely on SELinux or OpenBSD chroots (depending on prod env) to save me if all else failed
                                                              9. \n
                                                            \n

                                                            And of course the other things like firewalls (with whitelists for ports and blacklists for entire IP address blocks), key based ssh authentication, sshd configurations that don't make it possible to enumerate users, rate limiters, etc.

                                                            \n

                                                            Each layer of security is like a filter. If you have enough layers of filters it would take an unrealistic amount of force to push water through this filter. Although no system is perfectly safe from three letter agencies, a system with multiple layers of security is typically safe from drive-by attacks.

                                                            \n

                                                            Final exercise: intentionally write a php script that does path traversal. Run this on a system with SELinux. Try to coax /etc/passwd out of the server. Now try php-fpm instead of mod_php or vice-versa. You'll be surprised when even MAC doesn't protect your system.

                                                            \n

                                                            Even now, after spending almost a month and a half worth of after work hacker hours almost exclusively on 9, I enjoy it more than when I began and even more than when using it in semi-regular spurts in years past. The purpose of research operating systems is to perform research, be it about the design of the system otherwise. Where would we be without private namespaces? How can I use this idea in the real world? What would the world look like if we had real distributed computing instead of web browsers (which are the new dumb terminal)? Is there a use case for this in the real world? What can we learn from single layer security models? What can we do to improve the system?

                                                            \n

                                                            Plan 9 is perfect for this type of research. I'm considering writing an httpd in C and a werc-like (minus the parts I don't like) in C and modifying the namespace for the listener so that I can run a webserver on 9 without pulling in /bin in order to reduce the possibility of a shell escape.

                                                            \n

                                                            I think that in order to improve ourselves, we must be critical of ourselves. We must be critical of the things we enjoy in order to improve them and learn something new in the process. For software especially, there is no such thing as perfection, only least bad. And my final thought:

So, I give my take on these and what they mean relative to my life experiences. Individual mileage may vary. I also discuss the need to have a public facing social media presence that is active and consistent. Hide the private Socials and search to see what actually shows up when searching for yourself.

Luke (the CEO) and Gavin (CTO) of TerminusDB spill the beans on the history of the project, ontologies and why they still matter not only in a mobile-first world and why a website called DB Engines simply doesn't do the trick (putting it very diplomatically). Never mind the road ahead... (including quantum AI and some other fancy stuff - you heard it here first!). And also next week's lotto numbers (perhaps).

                                                            In this episode, Rho`n fixes the safety mechanism to his Neuton electric mower. Recently the automatic cutoff mechanism was getting finicky. Needing to pull the safety bar back just the correct amount to keep the mower running. Often needing to keep hands on both the left and right sides of the safety bar to prevent the mower from turning off.

                                                            \n

                                                            After opening up the housing holding the safety bars, it appeared that the tension spring which causes the bars to disengage from the switch when the bars are released was loose. This would allow the prong that the bars push into the switch contact to slip off the contact and slide overtop of the switch—turning off the mower. After tightening the coils and putting it back in place, the issue was resolved.

                                                            I find that the youtube web ui is designed to keep users on the site by feeding them an unending stream of information. Bright colors, distracting thumbnails, peanut galleries, etc. I prefer to consume my videos in the same way I consume everything else: via RSS.

                                                            \n

                                                            RSS is my favorite way of aggregating things that other people have made because it allows me, the user, to interact with their things

                                                            The only dependencies not on a standard UNIX system are newsboat and a video player. I also use yt-dlp to download videos for later viewing. I like mpv but you can substitute your own.

                                                            Youtube (currently) provides RSS feeds for channels.

                                                            \n

                                                            Sometimes channels have vanity URLs that can make it difficult to find the channel ID. Other times, the URL contains the channel ID. All youtube channel IDs start with the string UC so we can easily grep for them.

                                                            \n

                                                            In order to turn this channel ID into something useful, we create the following URL:

                                                            \n

                                                            \n

                                                            Google takeout can also be used to export youtube subscriptions.

                                                            \n

                                                            The export format is a CSV that contains the channel IDs for all of our subscriptions.

                                                            Newsboat reads it’s list of URLs from ~/.config/newsboat/urls. Every url we add to this list will be automaticlly fetched. You can make separate URL lists for your list of videos and list of standard text based RSS feeds

                                                            \n

                                                            If you have an exported CSV, you can easily modify it so that newsboat will accept it as a list of URLs by deleting row 1, column 1+comma, and replacing the comma between the URL and channel name with a tab character. Doing a sed 's/channel\\//feeds\\/videos.xml?channel_id=/g' on the file is an easy way to replace the website URL with the feed url. Newsboat only reads the first field of every row so the channel name can be kept for easier subscription management.

So to counter the misinformation, Snopes offers detailed explanations from genuine sources (like WHO, CDC) and sets the facts straight.

                                                            \nReiserFS is a general-purpose, journaling file system initially designed and implemented by a team at Namesys led by Hans Reiser and licensed under GPLv2. Introduced in version 2.4.1 of the Linux kernel, it was the first journaling file system to be included in the standard kernel. ReiserFS was the default file system in Novell's SUSE Linux Enterprise until Novell decided to move to ext3 on October 12, 2006, for future releases.
                                                            \n\nNamesys considered ReiserFS version 3.6 which introduced a new on-disk format allowing bigger filesizes, now occasionally referred to as Reiser3, as stable and feature-complete and, with the exception of security updates and critical bug fixes, ceased development on it to concentrate on its successor, Reiser4. Namesys went out of business in 2008 after Reiser's conviction for murder. The product is now maintained as open source by volunteers. The reiserfsprogs 3.6.27 were released on 25 July 2017.
                                                            \n\nReiserFS is currently supported on Linux without quota support. It has been discussed for removal from the Linux kernel since early 2022 due to a lack of maintenance upstream, and technical issues inherent to the filesystem, such as the fact it suffers from the year 2038 problem; it was deprecated in Linux 5.18, with removal planned for 2025.\n

                                                            I typically download and use one of the compressed memstick images. The mini image is fine but you probably want the regular memstick image if this is the first time you've ever installed FreeBSD. It alleviates some of the stress that comes with installing wireless drivers.

                                                            \n
                                                            \n

                                                            Initial installation

                                                            The standard steps for installing Linux apply:

                                                            \n
                                                              \n
                                                            1. disable secure boot
                                                              2. \n
                                                            2. enable USB booting
                                                              3. \n
                                                            3. select boot device at startup time
                                                              4. \n

                                                            Because this is hardware specific, it's a homework assignment for the audience.

                                                            \n

                                                            Installation

                                                            \n

                                                            FreeBSD has a menu driven installer that walks the user through various steps:

                                                            \n

                                                            1. set keymap (leave default if you don't know)

                                                            \n

                                                            2. set hostname

                                                            \n

                                                            3. select sets

                                                            \n

                                                            There are many sets to choose from. New users probably want to install all of them. I typically only install the lib32 set and add the rest later.

                                                            \n

                                                            4. Partitioning

                                                            \n

                                                            bsdinstall makes it easy to partition your drives. The Auto(ZFS) option is probably what you want as the default UFS configuration is unjournaled.

                                                            \n

                                                            In the Auto(ZFS) menu, for a single hard drive installation, you want to stripe one disk. Select your hard drive.

                                                            \n

                                                            If you want full disk encryption, select the Encrypt Disks option.

                                                            \n

                                                            You also want to bump up the swap size to ram*1.5 as a general rule (so, for 4g of ram you will set 6g of swap, for 8g or ram you set 12g swap). If you selected Encrypt Disks, you should also select Encrypt Swap

                                                            \n

                                                            When you are done, proceed with the installation. You will gt a confirmation message asking if you want to destroy the disk(s) you selected. This is your last chance to go back.

                                                            \n

                                                            If you selected Encrypt Disks, you will be presented with a password prompt. This is the disk encryption password, not any user password.

                                                            \n

                                                            5. Wait for sets to install

                                                            \n

                                                            6. Configure root user

                                                            \n

                                                            After the sets are installed, you will set a root password.

                                                            \n

                                                            7. Network Config

                                                            \n

                                                            If your wireless card is supported, all the hard parts are already done for you. If your wireless card is not supported, you might need to plug in an ethernet cable and compile the drivers into the kernel.

                                                            \n

                                                            Select your card (em* is ethernet, wifi cards are named after their drivers)

                                                            \n

                                                            If you choose wifi, the installer will scan for networks and give you a menu to select one. If the network is encrypted, you will be presented with a password prompt.

                                                            You will be presented with a menu that enables/disables services on system startup. You probably want all of them except local_unbound.

                                                            The next menu enables/disables security features. If nothing else, select disable_sendmail and clear_tmp

                                                            \n

                                                            Simply add your user. You might want to add him to the wheel group if you plan on using sudo. I set my shell to tcsh but you can always change this later. A

                                                            \n

                                                            You may want to install the handbook or modify any configurations you've made so far. This will take some time. When you are done, apply the config and exit.

                                                            Before you reboot the system and exit the installer, you are given a last opportunity to make any manual configurations. This is rarely needed for the average desktop user.

                                                            Installing packages

                                                            \n

                                                            Before we begin modifying the system, we need a better editor.

                                                            \n

                                                            The pkg utility is used in a nearly identical way to any Linux package manager. The syntax pkg $verb $object persists. Verbs include install, remove, update, upgrade, search, etc.

                                                            \n

                                                            Because the only editors installed by default are vi, ed, and ee, let's install vim.

                                                            \n

                                                            There are multiple vim flavors, I like vim-tiny.

                                                            \n
                                                            root@fbsd# pkg bootstrap\nroot@fbsd# pkg update\nroot@fbsd# pkg search vim\nroot@fbsd# pkg install vim-tiny\n
                                                            \n

                                                            We probably want sudo (or doas) also:

                                                            \n
                                                            root@fbsd# pkg install sudo\nroot@fbsd# visudo\n
                                                            \n

                                                            Find the line that says:

                                                            \n
                                                            # %wheel ALL=(ALL:ALL) ALL\n
                                                            \n

                                                            and move the # from the beginning of the line to enable the wheel group to do actions as root.

                                                            \n

                                                            \n

                                                            We can tweak the bootloader to make the system more desktop-like. Edit /boot/loader.conf

                                                            \n
                                                            # /boot/loader.conf\n# -----------------\n[ lots of default stuff ]\n\n# custom stuff\n\n# boot faster\nautoboot_delay=2\n
                                                            \n

                                                            Refer to loader.conf(5) for more tweaks and /boot/defaults/loader.conf for examples.

                                                            We can tweak the init system also. Edit /etc/rc.conf

                                                            \n

                                                            See rc.conf(5) and /etc/defaults/rc.conf for more information on what you can do.

                                                            Snapshotting a sane fresh installation

                                                            \n

                                                            At this point, it is wise to take a recursive snapshot of your FreeBSD installation. This provides us with an easy way to roll back to a fresh, known working system configuration.

                                                            \n
                                                            root@fbsd# zfs snapshot -r zroot@freshinstall\nroot@fbsd# zfs list - tsnapshot\n
                                                            \n

                                                            If the system becomes unrepairable, we can simply rollback instead of reinstalling with a simple command:

                                                            \n
                                                            root@fbsd# zfs rollback -r zroot@freshinstall\n
                                                            \n

                                                            To rollback every dataset, we can use xargs:

                                                            \n
                                                            root@fbsd# zfs list -t snapshot | grep freshinstall | cut -d ' ' -f 1 | xargs -I % zfs rollback %\n
                                                            \n

                                                            Using zfs snapshots before and after making any potentially dangerous configuration changes saves a lot of headache in the long run because zfs is accessible from the recovery shell. Rollback with caution, user data may be lost.

                                                            This varies depending on your GPU.

                                                            After installing this package, you will see a message on how to enable the driver for your specific hardware:

                                                            \n

                                                            To enable one of these, you will need to add a line to your /etc/rc.conf. The earlier you place this line in the file, the sooner the kmods will load. For intel graphics, for example, you will add the following line:

                                                            \n

                                                            Refer to The handbook's instructions on desktops for instructions on non-suckless (ie suckmore setups). I have tested some of them on FreeBSD. KDE and Xfce are reliable. GNOME is mostly reliable. If you are running a big DE, you might have to modify polkit rules to do things like reboot the system from the GUI. Many larger desktops rely on FreeDesktop.org components. I personally do not like dbus so instead I use the suckless tools.

                                                            Sometimes desktops behave unexpectedly on FreeBSD (ie users cannot manage power settings, reboot the system, etc). Make sure your login user is in the wheel group (it's your computer, you probably are already in the wheel group) and most of the issues will be resolved. For users you don't want in the wheel group, you'll need to write a few polkit rules.

                                                            \n

                                                            Additionally, big desktops are typically compiled without the graphical components for modifying network connections.

                                                            Similar to Arch or Gentoo, there is a bit of legwork left to the end user. You'll never know what you might learn about systems administration if you don't wilfully give yourself the opportunity.

                                                            Init system

                                                            \n

                                                            Instead of systemd, FreeBSD uses rc scripts for starting and stopping services. Everything is pretty much shell scripts. To modify the startup process, you simply edit /etc/rc.conf in a text editor.

                                                            \n

                                                            For systemctl like starting/stopping/enabling, you can do the following:

                                                            \n
                                                            root@fbsd# service sshd enable\nroot@fbsd# service sshd start\nroot@fbsd# service sshd restart\nroot@fbsd# service sshd stop\nroot@fbsd# service sshd disable\nroot@fbsd# service sshd onestart\nroot@fbsd# service sshd status\n
                                                            \n

                                                            Each service has it's own init file so sometimes a specific service might take different arguments than the standard ones you might expect.

                                                            \n

                                                            Networking

                                                            \n

                                                            Network interfaces are configured classically using ifconfig(8). If you want a network interface to persist across reboots, you add the information in /etc/rc.conf.

                                                            \n

                                                            WiFi is managed with wpa_supplicant. Refer to man wpa_supplicant.conf(8) for more information.

                                                            \n

                                                            FreeBSD uses tcsh(1) as the default shell and includes sh(1) for bourne-like compatibility. You can install bash if you want.

                                                            Package management

                                                            \n

                                                            There are two primary ways of managing software: binary packages and ports. Don't mix them if you don't know what you're doing, it can cause problems.

                                                            \n

                                                            To be brief: ports are like Gentoo. You spend a lot of time watching compiler output. The following programs help: synth, portmaster, poudriere.

                                                            \n

                                                            to be verbose: here is a quick guide on using the binary package management system:

                                                            \n
                                                            pkg update\npkg upgrade\npkg search foobar\npkg install foobar\npkg remove foobar\npkg autoremove\n
                                                            \n

                                                            As you can see, the syntax is nearly identical to dnf or apt.

                                                            \n

                                                            Filesystem

                                                            \n

                                                            The hierarchy of FreeBSD is slightly different than a typical Linux system. Refer to man hier(7) for more information.

                                                            \n

                                                            The biggest difference is that FreeBSD a logically organized system. For example: On Linux, everything seems to end up in /bin (which is a symlink to /usr/bin). Additionally, /sbin is just a symlink to /usr/sbin. On FreeBSD, the system is more organized. For example:

                                                            \n

                                                            /bin contains everything required to boot the system and /sbin contains everything required for fundamental administration.

                                                            \n

                                                            /usr/bin contains most everything else

                                                            \n

                                                            /usr/local contains everything installed by the package management system.

                                                            \n

                                                            User installed programs are configured in /usr/local/etc. This might be confusing at first but you'll get the hang of it.

                                                            \n

                                                            This logical separation might cause confusion when compiling software from source on FreeBSD but it's not too difficult to solve if you already know how about linker options and makefile modification.

                                                            \n

                                                            As for filesystems, apparently ext2, ext3, and ext4 have read/write support using the ext2fs(5) driver. I probably wouldn't boot from them but this exists. UFS is not journaled by default, proceed with caution. ZFS is very good.

                                                            \n

                                                            ZFS non-starter

                                                            \n

                                                            ZFS is cool because we can create partitions on a whim. Here is some shell output demonstrating listing datasets, creating datasets with a quota, destroying datasets, creating and using encrypted datasets, etc.

                                                            Really, I think FreeBSD is a viable desktop operating system for the types of people who already use Linux in a terminal-centric capacity. After all, UNIX is UNIX.

                                                            Overview

                                                            \n

                                                            Many programming languages have the concept of short-circuit evaluation in Boolean expressions. What this means is that in an expression such as:

                                                            \n
                                                            A AND B
                                                            \n

                                                            if A is false then the whole expression must be false, and B doesn’t have to be evaluated. That is because both arguments to AND have to be true for the overall result to be true.

                                                            \n

                                                            If A is true on the other hand, then B has to be evaluated to determine if the overall result is true.

                                                            \n

                                                            Similarly with:

                                                            A OR B
                                                            \n

                                                            if A is true then the whole expression must be true and B can be skipped without evaluation. This is because only one argument to OR needs to be true to return a true result.

                                                            \n

                                                            If A is false on the other hand, then B has to be evaluated to determine if the overall result is false.

                                                            \n

                                                            Both of these expressions are evaluated from left to right. This is not a given in all languages. Some use special operators such as 'and_then' and 'or_else' which explicitly perform short-circuiting and left-to-right evaluation.

                                                            In simple terms, short-circuiting is where the evaluation of an expression is stopped as soon as its outcome is determined.

                                                            \n

                                                            The Wikipedia article Short-circuit evaluation defines it as:

                                                            \n
                                                            \n

                                                            Short-circuit evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the overall value must be false; and when the first argument of the OR function evaluates to true, the overall value must be true.

                                                            Use case

                                                            \n

                                                            I was writing a Bash script in which I wanted to ask questions about various steps - should they be done or not? Alternatively, I wanted to be able to set an option to run without interaction and assume the answer is 'yes' to all questions.

                                                            \n

                                                            I’d encountered short-circuit evaluation before in Pascal and Perl so I wondered if I could use it in Bash.

                                                            \n

                                                            The expression I was trying to write was:

                                                            \n
                                                            if [[ $YES -eq 1 ]] || yes_no 'Create directory? %s ' 'N'; then\n    # Create directory\nfi
                                                            \n\n

                                                            The requirement was that if YES was set to 1 I didn’t want the function to be called at all.

                                                            \n

                                                            I was a little surprised, and very happy, to find that this is what happens.

                                                            \n

                                                            Here is the full example from the script that started me thinking about this issue - and therefore caused me to make this show:

                                                            \n
                                                            #\n# We need a show directory. If it doesn't exist then we'll create it because\n# other scripts will use it.\n#\nif [[ ! -d $SHOWDIR ]]; then\n    echo "${red}There is no directory for show $show${reset}"\n\n    #\n    # If the -Y option was not chosen ask with 'yes_no'. It -Y was chosen\n    # we're to go ahead regardless. This relies on the fact that Bash\n    # "short-circuits" logical expressions like this.\n    #\n    if [[ $YES -eq 1 ]] || yes_no 'Create directory? %s ' 'N'; then\n        mkdir "$SHOWDIR"\n        _silent "${green}Directory created for show $show${reset}"\n    else\n        _silent "${yellow}Not changed${reset}"\n    fi\nfi
                                                            \n

                                                            Notes:

                                                            \n
                                                              \n
                                                            • I have a Bash function that defines colours which is included into this script. That’s why you see 'echo \"${red}...${reset}\"' in the above. I also have a function to turn off colour by setting the relevant variables to empty strings.
                                                              • \n
                                                            • The 'yes_no' function takes a prompt string with an (optional) '%s' placeholder for the expected inputs and default. This is followed by the default: 'N'.
                                                              • \n
                                                            • The function '_silent' writes the message given as its argument, depending on the setting of a 'SILENT' variable set earlier.
                                                              • \n
                                                            \n

                                                            Should it be used?

                                                            \n

                                                            Case 1

                                                            \n

                                                            Bash uses short-circuiting in other contexts. This was discussed in the Bash Tips series, episode 10 with the example:

                                                            \n
                                                            [ -e /some/file ] || exit 1
                                                            \n

                                                            Here the test is performed using '-e' to determine if '/some/file' exists. The result is either true or false. If the test returns true then the overall result of the or is true and the evaluation is short-circuited so that the 'exit 1' is not invoked. If the test is false then the second expression has to be evaluated to determine the overall result, so the 'exit 1' is invoked and the script exits.

                                                            \n

                                                            Incidentally, the '[ -e file ]' construct is actually an instance of the test command so could be written:

                                                            \n
                                                            test -e /some/file || exit 1
                                                            \n

                                                            You might be familiar with command pipelines which use this technique, such as:

                                                            \n
                                                            sudo apt update && sudo apt upgrade
                                                            \n

                                                            If the 'apt update' is successful the 'apt upgrade' is run. If it fails then the second command is not run.

                                                            \n

                                                            Case 2

                                                            \n

                                                            We have seen the example that prompted me to make this show:

                                                            \n
                                                            if [[ $YES -eq 1 ]] || yes_no 'Create directory? %s ' 'N'; then\n    # Create directory\nfi
                                                            \n

                                                            This could have been written as:

                                                            \n
                                                            if [[ $YES -eq 1 ]]; then\n    # Create directory\nelif yes_no 'Create directory? %s ' 'N'; then\n    # Create directory\nfi
                                                            \n

                                                            I prefer the first way, but it could be argued in a development environment that co-workers might find it confusing.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            So, my conclusion is that short-circuiting is a desirable feature that I will continue to use.

These criminals often attack schools because they are\nprofitable targets. If all ransomware victims refused to pay, the\nattacks would stop. Indeed, paying up might be illegal: The Treasury\nDepartment released guidance last year noting that giving money to\nglobal criminal organizations can violate sanctions law.

While no full credit\ncard information was accessible, the information was enough to grant the\nattackers access to Verizon user accounts, which hold semi-sensitive\ndata such \"name, telephone number, billing address, price plans, and\nother service-related information,\" per a notice from Verizon.

                                                            Account access also potentially enabled attackers to process\nunauthorized SIM card changes on prepaid lines. Also known as SIM\nswapping, unauthorized SIM card changes can allow for the transfer of an\nunsuspecting person's phone number to another phone.

                                                            From there, the counterfeit phone can be used to receive SMS messages\nfor password resets and user identification verifications on other\naccounts, giving attackers potential access to any account they have, or\ncan guess, the username for. Consequently, Verizon recommended affected\ncustomers secure their non-Verizon accounts such as social media,\nfinancial, email and other accounts that allow for password resets by\nphone.

Devices that perform quantum computations are known as\nquantum computers. Though current quantum computers are too small to\noutperform usual (classical) computers for practical applications,\nlarger realizations are believed to be capable of solving certain\ncomputational problems, such as integer factorization (which underlies\nRSA encryption), substantially faster than classical computers.

That'll lay bare private communications, company\ndata and military secrets. Today's quantum computers are too rudimentary\nto do so. But data surreptitiously gathered now could still be sensitive\nwhen more powerful quantum computers come online in a few years.

This generally done using a dictionary attack, where an\nattacker will try known passwords and words until they find the one that\nunlocks an account. There are databases available on the internet that\ncontain personal names as well as dictionary and slang words, in scores\nof languages, along with passwords found in data breaches, and\nmore.

The AES algorithm\nis a symmetric block cipher that can encrypt (encipher) and decrypt\n(decipher) information. Encryption converts data to an unintelligible\nform called ciphertext; decrypting the ciphertext converts the data back\ninto its original form, called plaintext. The AES algorithm is capable\nof using cryptographic keys of 128, 192, and 256 bits to encrypt and\ndecrypt data in blocks of 128 bits.

In June 2003, the U.S.\nGovernment announced that AES could be used to protect classified\ninformation: For cryptographers, a cryptographic \"break\" is anything\nfaster than a brute-force attack – i.e., performing one trial decryption\nfor each possible key in sequence. A break can thus include results that\nare infeasible with current technology. Despite being impractical,\ntheoretical breaks can sometimes provide insight into vulnerability\npatterns. The largest successful publicly known brute-force attack\nagainst a widely implemented block-cipher encryption algorithm was\nagainst a 64-bit RC5 key by distributed.net in 2006.

Machine Learning, as the name says, is all about machines\nlearning automatically without being explicitly programmed or learning\nwithout any direct human intervention. This machine learning process\nstarts with feeding them good quality data and then training the\nmachines by building various machine learning models using the data and\ndifferent algorithms.

Once you've split up clips\nand put them in the right order on the timeline you can still adjust the\ncut point even though you previously split the clip because the clip is\nreferenced to the original file in the playlist.

As per usual I'd like to start by thanking the\npeople at HPR for making this podcast possible. HPR is a Community led\npodcast provided by the community for the community that means you can\ncontribute to. The HPR team have gone to great deal of effort to\nsimplify and streamline the process of providing podcasts. There are\nmany ways to record an episode these days using phones tablets PCs and\nalike. The hardest barrier is sending in your first show. Don't get too\nhung up about quality, it's more important just to send something in.\nThe sound quality of some of my early shows wasn't very good. If I can\ndo it anyone can and you might just get hooked in the process.

                                                            Well it's been almost a year since I've sent in a show. Looking at\nthe HPR site my last episode was back in November 2021. I suspect like\nmany others life has become more complicated and I find I have much less\nspare time and because I have much less spare time I have much less time\nto pursue my hobbies and because of this I have less to speak about and\nbecause of this I have less time to record what I've been doing and it\nall turns into to vicious circle. Fortunately I recently had some time\noff work and had a lovely holiday. During the holiday I ended up\nrecording some video which I decided I wanted to edit. I've done some\nvideo editing in the past using various video editing packages. The best\nand most recent of which is shotcut.

                                                            Shotcut workflow

                                                            \n

                                                            Start by creating a folder to hold all the required media files.\nAudio tracks and sound effects can be added to this folder later. Make\nsure all your video files are using the same frame rate in my case 30\nframes per second.

                                                            \n

                                                            Open each video file in VLC one at a time going through each video\nfile looking for the best portions of video. Make a note of where the\nbest portions of the video are by writing down the start and end points\nin minutes and seconds.

                                                            \n

                                                            I do this because the interface of VLC is more responsive than\nshortcut and the resolution of displayed video is far greater than the\npreview in shortcut. This makes it quicker and easier to find the best\nportions of video.

                                                            \n

                                                            Open shortcut and make sure the new project is set to the same frames\nper second as the media files you're working with, in my case 30 frames\nper second. You can check the frame rate of your project by looking at\nthe selected video mode in the new projects window. If you select\nautomatic it will ensure the project resolution and frame rate\nautomatically match that of your media files.

                                                            \n

                                                            Start by adding all the video files to the playlist, this can be done\nin a number of ways for example it can be done by clicking on the open\nfile button in the top toolbar or within the open files menu.\nAlternatively you can drag and drop files into the playlist. I find this\nto be the easiest way to add media files to a project. Once this is done\nsave your project.

                                                            \n

                                                            Drag the first file from the Playlist to the timeline making sure\nthat the start of the video starts at 0 seconds.

                                                            \n

                                                            Click on the timeline in the position where the first start point of\ninterest is needed. Use the S key to split the video at this point.\nDon't worry about being too accurate as this can be moved at a later\nstage.

                                                            \n

                                                            Repeat this process for the end point of interest.

                                                            \n

                                                            Repeat this again for all the other sections of start and end points\nof interest.

                                                            \n

                                                            Remove the unwanted sections of video by clicking on a section then\nhitting the delete key. This will remove the unwanted section leaving an\nempty space behind.

                                                            \n

                                                            Once all the unwanted sections are removed click on the sections of\nvideo and pull them to the left to close the gaps up. I find it useful\nto leave some space between the good sections of video as it makes it\neasier to see where splits are and makes it easier later on to rearrange\nthe order of the individual clips.

                                                            \n

                                                            Check the start and end points of the remaining sections of video to\nsee that the start and end points stop in the correct place. You can do\nthis by clicking the play button on the preview window. The video start\nand end points can be adjusted by dragging the section left or right in\nin the timeline section; this is where leaving spaces Between each\nsection of video can be handy as it allows for fine tuning.

                                                            \n

                                                            Add a new blank video track to the timeline to hold the next video.\nNote this wasn't required when adding the first video track but it is\nneeded for each subsequent track. A video track can be added by right\nclicking on an empty portion of the timeline and selecting add video\ntrack. Alternatively use the ctrl + I key.

                                                            \n

                                                            Drag your second video from the playlist onto the newly created blank\nvideo track in the timeline. As before make sure that the start of the\nvideo starts at 0 seconds.

                                                            \n

                                                            Before previewing any section of the second video track click the\nsmall eye shaped hide icon in the left section of the first video track\nlabelled output. This will prevent previewing both video tracks at the\nsame time.

                                                            \n

                                                            Repeat the process above of chopping the second video track into\nsections using the S key to split the video up. Remove the unwanted\nsections. Finally adjust the start and end points of the remaining\nsections.

                                                            \n

                                                            Repeat the steps above to add the remaining video files one at a time\nfrom the playlist to the timeline.

                                                            \n

                                                            When complete you end up with separate video tracks in the timeline\neach containing good sections of video.

                                                            \n

                                                            At this stage I can't be too specific about how to continue as there\nare a number of different options depending on your particular Project.\nYou can for example start by combining the good sections of video into\none video track by dragging them from one track to another then add if\nrequired an audio track or you can add the audio track first and then\ntry to sync things up to the audio track moving bits and pieces of video\ninto one video track remembering to hide the unwanted sections of video\nby clicking on the small hide eye icons. Don't do too much editing\nwithout saving the project. If you get a message about low memory save\nthe project then reopen it.

                                                            \n

                                                            To export the final video click on the export button in the toolbar.\nI pick the default option, this creates an H.264/AAC MP4 file suitable\nfor most users and purposes. You can check the frame rate is the same as\nyour original media files by clicking on the advanced tab. Click the\nexport file button and give it a file name. It may take some time to\ncreate the export file. This will be dependent on the speed of your\ncomputer and the length and resolution of your project.

                                                            While Shotcut is far from perfect on my puny PC it is surprisingly\nusable and stable and is the best option I’ve found so far.

                                                            \n

                                                            Finally here are some general shotcut tips I have when doing video\nediting on a puny PC with limited ram, slow processor and built in\ngraphics card such as mine.

                                                            General Tips\nwhen working with a low powered PC

                                                            \n

                                                            Close all open applications leaving only shortcut open this helps\nwith RAM usage

                                                            \n

                                                            Shortcut is surprisingly stable with a feeble PC such as mine. I\nwould still recommend saving your project regularly as it is quick and\nvery easy to do.

                                                            \n

                                                            If you get a message about running out of RAM then try not to do too\nmuch more editing before saving the project. Once saved close shotcut\nand then reopen it. The longer your project is and the higher your\nproject resolution the more RAM you will need.

                                                            \n

                                                            When you are about to export your final video save the project close\nshortcut reopen shotcut and immediately export your project as any\nprevious editing may be taking up precious ram.

                                                            \n

                                                            Be patient when clicking on the timeline to repositioned the play\nhead. Always wait for the preview window to update. This can sometimes\ntake a few seconds.

                                                            \n

                                                            When trying to sync video to audio you need to zoom in in quite a\nlong way before getting an audio preview. When doing this and moving the\nplay head you'll get a choppy version of the audio with this it is still\nperfectly possible to find the beat of the music allowing you to sync\nyour video to the music. If this doesn't seem to work for you then try\nzooming in closer.

                                                            \n

                                                            Ok that's about it for this podcast. Hope it wasn't too boring and it\nmade some sense. If you want to contact me I can be contacted at\nmrxathpr at googlemail.

                                                            • First, authentication. This is the process of verifying the\nvalidity of something; in our case, user credentials/identity. The most\ncommon way to authenticate is: USERNAME and PASSWORD.\nThis is just a single layer (single-factor authentication) and isn’t\nenough to discourage attackers.

                                                            • Second, 2FA (Two-factor Authentication). 2FA increases the\ndifficulty for attackers by providing users an additional layer of\nsecurity to accomplish authentication. Common 2FA methods are: TOTP/OTP\n(the One Time Password), Authenticator\nApplications (Bitwarden, KeePassXC,...), and Security Keys (Yubikey). This works similar to ATMs;\nto authenticate the user must provide both knowledge (account\nPIN) and a physical object (bank card).

                                                            • Last, but not least, MFA (Multifactor Authentication). Similar to\n2FA, MFA offers users security with the addition of biometrics\n(fingerprint scan, retina scan, facial recognition, and voice\nrecognition). Attackers must overcome the knowledge factor, Possession\nfactor, Inherence/Biometric factor, Time factor, and sometimes Location\nfactor.

                                                            Overview

                                                            \n

                                                            Have you ever written a Bash script (or any shell script) where you\ngenerate a message like 'Found 42 files' and the day comes\nwhen it reports 'Found 1 files'?

                                                            \n

                                                            Have you been irritated by this? I have, and I go to lengths to deal\nproperly with (English) plurals in my Bash scripts.

                                                            \n

                                                            Method 1

                                                            \n

                                                            The simplest solution would be to use an 'if'\nstatement:

                                                            \n
                                                            if [[ $fcount -eq 1 ]]; then\n    echo "Found 1 file"\nelse\n    echo "Found $fcount files"\nfi
                                                            \n

                                                            This works, but to have to do it for every message would be a\npain!

                                                            \n

                                                            Method 2

                                                            \n

                                                            The next approach to this problem might be to write a Bash\nfunction.

                                                            \n
                                                            pluralise () {\n    local singular="${1}"\n    local plural="${2}"\n    local count="${3}"\n\n    if [[ $count -eq 1 ]]; then\n        echo "$singular"\n    else\n        echo "$plural"\n    fi\n}
                                                            \n

                                                            This can be called as follows:

                                                            \n
                                                            $ i=1; echo "Found $i $(pluralise "file" "files" $i)"\nFound 1 file\n$ i=42; echo "Found $i $(pluralise "file" "files" $i)"\nFound 42 files
                                                            \n

                                                            The string being displayed with echo contains a command\nsubstitution ('$(command)') which returns\n'file' or 'files' depending on the value\ngiven.

                                                            \n

                                                            The first two arguments can be more complex than plain strings:

                                                            \n
                                                            $ i=1; echo "There $(pluralise "is 1 light" "are $i lights" $i)"\nThere is 1 light\n$ i=4; echo "There $(pluralise "is 1 light" "are $i lights" $i)"\nThere are 4 lights
                                                            \n

                                                            The pluralise\nfunction is available for download.

                                                            \n

                                                            Method 3

                                                            \n

                                                            The GNU project has developed a set of utilities called the GNU\ngettext utilities consisting of tools and documentation for\ntranslation. This is a large subject which is not suitable for a short\nHPR episode such as this one.

                                                            \n

                                                            Among the tools is 'ngettext' which performs the\nfunction we have been discussing - choosing among plural forms. It also\nimplements translations if desired (and translation files are provided\nas part of the software being developed).

                                                            \n

                                                            We will not discuss the translation topic here, but the choice of\nplurals is something that can be used in Bash scripts.

                                                            \n

                                                            The 'ngettext' tool takes three mandatory\nparameters:

                                                            \n
                                                              \n
                                                            • MSGID - the singular form of the text
                                                              • \n
                                                            • MSGID-PLURAL - the plural form of the text
                                                              • \n
                                                            • COUNT - the value used to make the singular/plural\nchoice
                                                              • \n
                                                            \n

                                                            There are other optional parameters and options but they are not\nrelevant here.

                                                            \n

                                                            The tool can be used in exactly the same way as the\n'pluralise' example above.

                                                            \n
                                                            $ i=1; echo "There $(ngettext "is 1 light" "are $i lights" $i)"\nThere is 1 light\n$ i=4; echo "There $(ngettext "is 1 light" "are $i lights" $i)"\nThere are 4 lights
                                                            \n

                                                            Whether you use this or a Bash function is your choice.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            I have been using ngettext in my scripts since I\ndiscovered it. If you also need to provide messages in your projects in\nother languages then this might be a good idea.

                                                            I admit that my understanding of the GNU gettext project\nis superficial, so, on reflection it might be better to use a Bash\nfunction, since I don’t currently need all of the features GNU\ngettext provides.

On October 10, 2022, European authorities arrested 31\nsuspects across three nations. The suspects are believed to be related\nto a cybercrime ring that allegedly advertised an “automotive diagnostic\nsolution” online and sent out fraudulent packages to their victims. The\nfraudulent packages contained malware and once installed onto the\nvictims vehicle, the attackers were able to unlock the vehicle, start\nthe ignition, then steal the vehicle without the physical key fob.\nEuropean authorities confiscated over €1 million in criminal assets\n(malicious software, tools, and an online domain).

                                                            I installed a new 1TB Crucial MX500 SSD into my work computer. While\nwe are mostly a Windows based business, as the IT guy I do get a bit of\ndiscretion when updating my own machine (i.e. I get to solve all the\nproblems I create). Last year, I decided to run the Pop!_OS distribution\nof Linux on my work computer and run Windows in a VM on it. Recently the\nWindows image had grown and was causing disk space notifications. This\nprompted the additional hard drive.

                                                            \n

                                                            During the initial installation of Pop!_OS, I remember deciding not\nto bother with installing Linux Volume Management (LVM). I have used it\nin the past, but I am still much more comfortable with the old style\ndevice mapping and mounting disk partitions to directories. I even\nrationalized that if I needed to add more space, I will just add a new\ndisk with one big partition and map it to the home directory.

                                                            Now a year later I am adding a new HD and thinking, I really hate all\nthe space that is most likely going to be wasted once I move the Windows\nimage to the new drive. Ok, I guess I should figure out how to install\nLVM, and use it to manage the space on both drives. Luckily there a\nnumber of good blogs to be found on adding LVM to an existing system.\nThe following are the steps and commands I used to accomplish my\ngoal.

                                                            \n

                                                            Commands

                                                            \n

                                                            Most of the following commands need to be run as root. I decided to\nchange to root user instead of typing sudo before every command. The\nbasic steps to creating a single filesystem sharing the storage space\nbetween two physical disk partitions are:

                                                            \n
                                                              \n
                                                            1. Let LVM know about the new disk.
                                                              2. \n
                                                            2. In my case, create a volume group and add the new disk and its full\nstorage space to it.
                                                              3. \n
                                                            3. Copy the disk partition with the root filesystem from the origin\ndisk to the new volume group
                                                              4. \n
                                                            4. Expand the root filesystem on the volume group to the full size of\nthe volume group.
                                                              5. \n
                                                            5. Update system configuration to boot with the root filesystem on the\nnew volume group.
                                                              6. \n
                                                            6. Let LVM know about the old root disk partition.
                                                              7. \n
                                                            7. Add the old root partition to the volume group.
                                                              8. \n
                                                            8. Expand the root filesystem on the volume group to include the new\nspace in the volume group.
                                                              9. \n

                                                            Hmmm why can't it copy the smaller disk onto a larger one?

                                                            Whoops, the default unit for the lvcreate is MB, and I forgot to add\nG to my size. A good reason to always include units in whatever you do\n:) Also, pay attention to any reports printed at the end of a successful\ncommand. When I scrolled back I realized it told me the size it\ncreated.

                                                            Lately I've been thinking a lot about power consumption when it comes\nto computing. Intuitively, I know that arm devices pull significantly\nless power than amd64 machines but I've never really tested this in the\nreal world. So, some preliminary power consumption stats:

                                                            These numbers are fairly easy to find: just look at the power supply\nfor a MAXIMUM OUTPUT value or something similar. This is the point at\nwhich the power supply fails so we can safely assume this is the maximum\npower draw for any given computer. Of course, this is DC output and not\nAC output and anyone who knows anything about electricity knows that\nconverting AC to DC is expensive but these values are useful as a\ngeneral estimate. I\nwrote something similar about computer power consumption some time\nago

                                                            My goal in all of this was to find a self contained computer that\nruns UNIX, doesn't take much power, isn't a consumption rectangle\n(smartphone), and can be charged from both AC with a rectifier and\nstored DC without an inverter. Charging from existing stored power was\nprobably the most novel consideration. Everything else is a given.

                                                            A few obvious answers come to mind:

                                                            The PBP is an obvious choice. It's an open hardware ARM laptop that\ncan be charged via a barrel cable (AC->DC) or via USB-C. Charging\nfrom USB-C is a very useful feature because it means I can easily choose\nbetween charging from the mains where efficiency loss is acceptable and\ncharging from a DC source where efficiency loss is unacceptable.

                                                            The actual use case is \"what computer can I run off of a old car\nbattery or the alternator in my car without burning power with an\ninverter?\". I'll revisit this use case in a later section.

                                                            I took these notes immediately upon opening the PBP. They remain\nunedited because I want to be honest on the first impressions.

                                                            I was worried about DHL dropping my package out of a plane. Or\nleaving it out in the rain. Or having one of the employees use it as a\nsoccer ball. Or having the thing get stuck in customs. It ended up\narriving safely and was packaged well. Two boxes within a padded\nenvelope within another envelope. Surprising for DHL.

                                                            1. load bootloader from nvram

                                                            2. query storage device

                                                              4. \n
                                                            4. otherwise, use the bootloader from nvram
                                                              5. \n

Different kernels show different garbled nonsense so\nit's a bit of fun. The keyboard does not work in u-boot.

Even sadder, no Plan 9 ported\nto PBP either. Running a \"distro based on a distro based on a distro\nbased on arch\" is the antithesis of my computing philosophy. Luckily\nenough, there is a big list\nof operating systems that run on the PBP. Most of these are distros\nbased on distros based on distros. OpenBSD instantly appeals to me but\nthere is no support for graphical TTYs as of yet (installation must be\nperformed over serial) so this is a non-starter. NetBSD also appeals to\nme but no wifi in 9.x, only in -CURRENT. A wide selection of actually\nusable software, take your pick.

                                                            The PBP has 6 cores (2 fast, 4 slow) and 4gb ram. The cpu is fairly\nslow but entirely usable. On large procedural jobs like software\ncompilation, it's painful. For concurrent jobs, it's mostly fine.

                                                            As expected, the PBP is slower when it comes to compilation than a\nstandard amd64 machine. Surprisingly enough, NetBSD was significantly\nslower than Manjaro. This is likely due to the Linux kernel knowing how\nto better handle multiple CPUs with varying speeds.

                                                            Did the PBP fulfill it's\nneeds?

                                                            \n

                                                            The intended use case was \"UNIX machine I can charge from an existing\nbattery or alternator\". This immediately invokes ideas of \"why would I\neven need wifi support?\"

                                                            \n

                                                            Ultimately, I ended up flashing a bad image to the SPI flash chip and\nI cannot get the system to boot (or even show signs of life). I have\nattempted to enter maskrom mode to re-flash the SPI but I am\nunsuccessful. There are a few other things I need to try. I'll update\nthis if I ever get it functional again.

                                                            \n

                                                            I did not have the opportunity to test the machine in the exact\nenvironment I got it for but it was fun before I bricked it. Again, a\nplace for updates.

                                                            Who is the PBP for?

                                                            Obviously, the types of people who are interested in pine64 devices\nand similar SBCs are already computer owners (if not computer hoarders).\nIt's unlikely that the PBP will become my (or anyone's) primary computer\nbut that doesn't mean that it's useless. The entire point of arm SBCs is\nto have fun so why not have fun?

                                                            \n

                                                            Just don't flash your SPI if you want it to work as expected.

                                                            Some final thoughts on\nopen hardware

                                                            \n

                                                            Oftentimes, before purchasing freedom centric hardware, I search for\na few reviews so that I can set my expectations correctly. Oftentimes\nthese reviews are very epidermal: they're not even skin deep.\nThese reviewers are consumers producing reviews for a consumer audience,\nnot hackers producing in-depth reviews for hacker audience. These types\nof reviews are frustrating for me but fundamental flaws seem to shine\nthrough the lack of thoroughness.

                                                            \n

                                                            I think that the general negative reviews on open hardware largely\nstem from unrealistic expectations. The community seems to over-hype\nmany of these devices out of ignorance, stating that $freedomDevice is\nthe $proprietaryAlternative killer, the end all be all device that will\nusher in the year of the Linux $deviceCategory. Oftentimes, it seems\nlike the high expectations fall flat when confronted with the reality of\nopen hardware: it's either way too expensive or way too\nexperimental.

                                                            \n

                                                            It seems like many of these devices are lacking both developer time\nand users who are both enthusiastic and knowledgeable. Pitfalls of\nmobile UNIX include bad power management, difficulty hotplugging\nwireless chipsets, graphical interfaces attempting to cope with the fact\nthat they don't have a physical keyboard, etc. There is still much work\nto be done. As for users, it seems that the most enthusiastic users\nalways have the impression that $linuxDevice will have 1:1 feature\nparity with $proprietaryDevice. Maybe it's just that the loudest users\nare heard or that we only want to hear utopian dreams of a free software\nfuture.

                                                            \n

                                                            A prime example of this conflict between expectations and reality:\nLinux smartphones. It doesn't help when many linux smartphones over the\nyears were advertised as a viable android competitor rather than\nanything other than what they actually were: an arm board attached to a\ntouch screen and a modem.

                                                            \n

                                                            I oftentimes ask myself \"what is open source worth?\". How much money\nare you willing to throw at an idea you like? Surely, money thrown at an\nidea you like is being used better than money thrown at an idea you\ndon't like. In many cases, it seems like open hardware devices are more\nexpensive than their proprietary counterparts for a few reasons. The two\nlargest reasons are small batch manufacturing and the fact that open\nhardware isn't subsidized by pre-installed adware (in the case of nearly\nevery device that comes pre-loaded with proprietary software).

                                                            \n

                                                            What is open source worth? A few extra dollars, a few extra hours of\nconfiguration, a few extra papercuts, and a clean conscious knowing that\nI didn't pay for yet another windows license I will never use and will\nnever get a refund for. Open source is worth investing in because the,\nalbeit slow, improvements to open hardware and software have wider\nimplications than just \"buying a laptop with Linux pre installed\".

                                                            SMITE is a free-to-play online MOBA (Multiplayer Online Battle Arena)\nand ARTS (action real-time strategy) game developed by Titan Forge Games\nand published by Hi-Rez Studios. The game is currently available on PC,\nXbox One, PlayStation 4 and Nintendo Switch. Players choose from a large\nselection of playable gods, immortals, and creatures from ancient\nmythology and join session-based arena combat. Each of the playable\ncharacters have their own unique abilities and fighting styles. This\nsession-based arena combat is mostly 5 players against another set of 5\nplayers, but there are several other Game Modes with different rules and\nobjectives, and the goal in most of them is to defeat the Titan located\nin the opposite team's base while protecting your own Titan.

                                                            Inetd, the internet\nsuper-server

                                                            \n

                                                            Inetd is slowly becoming one of my favorite daemons. It makes writing\nprograms that talk over the network super easy. Inetd handles all of the\nhard socket stuff and allows admins to write simple UNIX-ey programs.\nInetd is useful because it allows us to write services that only run\nwhen they are requested in order to reduce total system load.

                                                            \n

                                                            How inetd works

                                                            \n

                                                            Inetd can be conceptualized as a sort of \"wrapper daemon\". Inetd is\nalways running despite the fact that many of it's sub-services are\nnot always running.

                                                            \n

                                                            Inetd listens on a specific port. When it gets a request, it handles\nall of the hard socket parts. This request is then passed to one of our\ninetd services

                                                            \n

                                                            We will use a simple server that echoes the request back to the user\nas an example. We will call this inetd service\nechod

                                                            \n

                                                            Inetd passes requests to echod as text.\nechod will read from stdin and write to stdout. Everything\nwritten to stdout is passed to the client. echod will then\nexit.

                                                            \n

                                                            echo server example

                                                            \n

                                                            I use OpenBSD on my webserver. Sadly, systemd sockets have replaced\ninetd on many linux systems. systemd sockets are entirely painful to\nuse. I can't verify that these examples will work on non-OpenBSD systems\nbut the openbsd-inetd package is available on a wide\nvariety of debianoiads.

                                                            \n

                                                            Let's write out out echod service and the configuration\nfiles required to get it working.

                                                            \n

                                                            Edit /etc/inetd.conf

                                                            \n
                                                            # port  socket type protocol    wait/nowait user    server program      server arguments(optional)\n9999    stream      tcp         nowait      daemon  /opt/echod/echod.sh
                                                            \n

                                                            And our echod service file, located at\n/opt/echod/echod.sh:

                                                            \n
                                                            #!/bin/sh\nwhile read l; do\n        echo $l;\ndone;\n\nexit 0;
                                                            \n

                                                            Be sure to chmod +x echod.sh and\nrcctl enable inetd && rcctl start inetd or it won't\nrun.

                                                            \n

                                                            Testing

                                                            \n

                                                            Sometimes you can use curl to test a service but I will use netcat\ninstead because it doesn't assume http.

                                                            \n
                                                            $ echo "foobar" | nc -N localhost 9999\nfoobar\n$
                                                            \n

                                                            You can also use telnet to test the service:

                                                            \n
                                                            $ telnet localhost 9999\nTrying 127.0.0.1...\nConnected to localhost.\nEscape character is '^]'.\nfoo\nfoo\nfoobar\nfoobar\necho back\necho back\n^]\ntelnet> Connection closed.\n$
                                                            \n

                                                            Finger server example

                                                            \n

                                                            Many months ago, I wrote a finger server to learn more about how\ninetd works (and to write a finger daemon that doesn't allow for\nenumerating non-regular users). You can download the source\ncode for my finger server from my gitlab.

                                                            \n

                                                            This finger server only allows information from users who have a home\ndirectory in /home/ to be displayed. It also has hard-coded\nfilenames it looks for. Example output looks something like:

                                                            \n
                                                            $ finger binrc@localhost\n[localhost/127.0.0.1]\nbinrc@openbsd.my.domain\n\nhttps://0x19.org\n\nWorking on an HPR episode\n\nbinrc.nospam@nospam.protonmail.com\n\nNo .pgpkey\n\n$

                                                            Gopher server example

                                                            \n

                                                            Currently, I am working on a gopher server that runs through inetd to\nlearn more about how gopher works (and to write a gopher server that\ndoesn't allow for path traversal). I have yet to add autoindex support\nbut I thought it would be good to include anyway because it really\ndemonstrates how simple it can be to write an inetd service. You can download the source code\nfor my gopher server from my gitlab.

                                                            \n

                                                            This gopher server reads input from standard in and prints the\nrequested file to standard out. Writing an inetd service can be as easy\nas writing an application specific version of cat(1).

                                                            \n

                                                            Giving the service SSL

                                                            \n

                                                            You can pair inetd with relayd to make any inetd service use ssl. In\nthis example, I am symlinking my existing httpd certs obtained with acme.sh

                                                            \n
                                                            # ln -s /etc/ssl/example.com.fullchain.pem /etc/ssl/example.com\\:9998.crt\n# ln -s /etc/ssl/private/example.com.key /etc/ssl/private/example.com\\:9998.key
                                                            \n

                                                            A sample relayd configuration looks like:

                                                            \n
                                                            log connection\n\ntcp protocol "echod" {\n        tls keypair "example.com:9998"\n}\n\nrelay "echod" {\n        listen on example.com port 9998 tls\n        protocol "echod"\n        forward to 127.0.0.1 port 9999\n}
                                                            \n

                                                            After enabling and starting relayd, it will now be listening on port\n9998. When it receives traffic on 9998, it\nwill perform all of the fancy cryptography stuff and pass the request to\nlocalhost:9999. Since relayd is listening on\n9999 and passing requests on 9999 to the echo\nserver, we are now running an echo server with ssl.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            Do I run inetd in production? No, not really. I have in the past but\nI haven't needed it seeing as finger, echo, and gopher are dead\nprotocols. Even if inetd is largely useless in the modern era, it's\nstill fun to play with.

                                                            I have wanted an e-ink based e-reader for a while. Reading on my\ncomputer is ok. Reading on my phone is doable, but is very annoying. If\nI don't keep my finger on the screen, it will go blank and then I have\nto make sure and press the power button to bring the screen back to life\nbefore it locks. A tablet would probably be a nice compromise, but I\nreally wanted to try out an e-ink display, and didn't want the potential\ndistractions of a more multi-purpose device. I wanted not only and e-ink\ndisplay, but also one that ran a linux operating system, and a reader\nthat I could potentially put a different Linux distribution on, or\nmodify myself somehow. When asked what I wanted for Christmas this year\nby my wonderful girlfriend, I sent her a link to the KOBO Libra H20.

Has very nice features for editing meta data and\norganizing my books. It will also transfer the books to the Libra H20\nand update its internal database. One thing I found is KOBO does have\nits own EPUB format that it uses to optimize display of books. In\nparticular, it fixes an issue where images in standard EPUB format don't\nscale to the size of the page. Calibre has a plugin system, and a 3rd\nparty plugin is available that will convert a standard EPUB format to\nKePUB when you transfer the book to the e-reader.

                                                            I have been enjoying my KOBO reader. It can feel a little slow at\ntimes, especially rendering pdf files where the page is a picture of the\ntext and not made up of electronic characters, and it does render images\nin standard epub format a bit small at times. Other than these two\nthings, it is very easy to read in all lighting settings, and I enjoy\nreading using the KOBO.

Then we look at how batch files can be nested, that is, how one batch file can call another batch file, thus chaining batch files together.

                                                            A question came up in November regarding the HPR RSS feeds. All of\nthe URLs in these feeds use 'http' as opposed to\n'https'.

                                                            \n

                                                            Although this may seem odd, this is a fairly common thing to do,\nbecause the RSS standard (such as it is) does not cater for\n'https' links. There is a concern that passing an RSS feed\nwith such links to a validator (such as the W3C Feed Validation Service)\nwill result in it being marked as invalid.

                                                            A battery converts chemical energy into electrical energy by a\nchemical reaction. Usually the chemicals are kept inside the battery. It\nis used in a circuit to power other components. A battery produces\ndirect current (DC) electricity (electricity that flows in one\ndirection, and does not switch back and forth).

                                                            Using the electricity from an outlet in a building is cheaper and\nmore efficient, but a battery can provide electricity in areas that do\nnot have electric power distribution. It is also useful for things that\nmove, such as electric vehicles and mobile phones.

                                                            Batteries may be primary or secondary. The primary is thrown away\nwhen it can no longer provide electricity. The secondary can be\nrecharged and reused.

Attackers were able\nto access unauthorized customer data; business transactions and other\ninteractions between Microsoft and its customers. SOCRadar, a cyber security company, is\ncalling the security breach “BlueBleed”. SOCRadar discovered the breach\non September 24, 2022 Microsoft is downplaying the security breach but\nsecurity researcher Kevin Beaumont isn't buying it. Mr. Beaumont suggest\nMicrosoft dropped the ball on informing its customers, and federal\nregulators, of the security breach in a timely manner.

After install, the malicious android\napps automatically run services without the user knowing or interacting\nwith the app. That’s right, they auto run after install. These malicious\napps then disguise themselves by changing their icon to the “Google\nPlay” icon and renaming to themselves to “Google Play” or “Settings”.\nThe malicious apps quickly create permanent malicious services. McAfee’s\nMobile Research Team demonstrates the resilience of the malware by using\nkill\n-9 on the service processes. More malicious processes generate\nimmediately as if nothing happened.

                                                            \n

                                                            I have recently been wondering about the use of abbreviations which\nare built from the first letter of a word followed by a number and the\nlast letter. The number represents the count of letters between the\nstart and end letter. Thus accessibility becomes\na11y. This came to light (to me anyway) during an email\nexchange with Mike Ray regarding the accessibility issues on the tag\nindex page on the HPR site. The website issues were resolved, but I was\nleft wondering how useful the term a11y is, or whether it\njust jars with me!

                                                            \n

                                                            According to the Wikipedia article\nthis type of word is known as a numeronym, but they may also be\nreferred to as alphanumeric acronyms, alphanumeric\nabbreviations, or numerical contractions.

                                                            \n

                                                            As the Wikipedia article notes these types of abbreviations are\nalmost always used to refer to their computing sense — such as\ng11n for globalisation — in the context of computing,\nnot the general context.

                                                            Looking at a11y as an\nexample

                                                            \n

                                                            While I sympathise with the motivation behind using\n'a11y' to mean accessibility, I do find it odd and\ncounter-intuitive. I often find myself pondering the acceptability of\nthis type of abbreviation. How many other words in common English fit\npatterns like this I wonder? Quite a few I would expect. How does this\naffect the admissibility of such abbreviations?

                                                            \n

                                                            Not only are they adventurously strange to my simple brain, but I\nfind them to be aesthetically displeasing. My experiments with the\nstandard Linux dictionary looking for words that fit this pattern I find\naffirmatively supportive of this view. I describe this experiment\nlater.

                                                            Algebraically, it is to be expected that there are many dictionary\nwords of 13 characters which start with 'a' and end with\n'y'. Looking at them allegorically, such numeronyms convey\nlittle meaning except in very limited contexts since the motivation\nseems to be to reduce the need to type long words. Alternatively, if\nthey were accepted by data entry software and expanded automatically a\nbetter case could be made for applicability, but only one word could be\nassigned to a numeronym.

                                                            In my mind there is a certain artificiality in the use of these\nabbreviations.

                                                            The following piece of Bash scripting scans the file\n/usr/share/dict/words and picks out words which match the\na11y pattern (after removing those ending in\n's). It writes the word and the numeronym\ngenerated from it, which it computes, though it’s unnecessary in this\ncase because they all generate the same numeronym. I did it this way\nbecause I wanted to apply the algorithm to other words:

                                                            \n

                                                            Here’s a variant which selects all words which are 8-20 letters long,\nand picks 20 at random to which to apply the numeronym\nalgorithm:

                                                            This is a made-up (possibly nonsensical) word, but I thought I could\ntry my algorithm on it:

                                                            \n

                                                            Numeronyms don’t appeal to me. Notwithstanding my little jokes above,\nI know the proposal is not to replace all longer words\nwith them; this would cause chaos! However, as a means of denoting long\nwords this seems wrong.

                                                            \n

                                                            I assume that their evolution occurs like this:

                                                            \n
                                                              \n
                                                            • We use a word often in a particular context
                                                              • \n
                                                            • The word is long and not easy to type
                                                              • \n
                                                            • For the sake of speed and to avoid typographic errors we make a\nnumeronym
                                                              • \n
                                                            • We then tell the world that \"i18n\" (as an example)\nmeans internationalisation.
                                                              • \n
                                                            • Those in the know have no problems with it but many people who\nencounter it later puzzle over it - as I am doing here!
                                                              • \n
                                                            \n

                                                            It seems fair to say that this obscure process has fulfilled the need\nto abbreviate this awkwardly long word - in the limits of the context\nwhere it has evolved. However it has not conveyed information very well;\nit has mainly benefited those who write (or read) documentation relating\nto the context.

                                                            \n

                                                            Many editor and word processor applications have the facility of\nexpanding abbreviations like this, in my experience. I would prefer to\nuse this rather than embed the coded abbreviation into the language.

                                                            \n

                                                            On the other hand, I’m OK with\nPneumonoultramicroscopicsilicovolcanoconiosis being replaced by\nP43s!

                                                            \n

                                                            I will confess that I had a similar reaction to XKCD’s “Up Goer Five”\nidea. He explains the Saturn 5 - “Explained using only the ten\nhundred words people use the most often”.

                                                            \n

                                                            Maybe you disagree with me! If so, feel free to add a comment to this\nshow — or indeed, record a show of your own!

                                                            It's often referred to as loopback, home, or\nlocalhost and is usually defined in\n/etc/hosts

                                                            \n

                                                            The address is used by programs running on a given computer to\ncommunicate with other programs running on the same computer.

                                                            IPv4 network standards reserve the entire address block 127.0.0.0/8\n(more than 16 million addresses) for loopback purposes.

                                                            If you are confused, then just think of it like you when your boss\nsays \"I'm going home now, you should also go home.\"

                                                            \n

                                                            It's clear that they mean \"I'm going to my home now,\nand you should also go to your home.\"

                                                            \n

                                                            So the address 127.0.0.1 on pc_middle is only available\non pc_middle, and equally the address 127.0.0.1 on\npc_right is only available on pc_right.

                                                            \n

                                                            The server is listening on its loopback address 127.0.0.1 on\npc_middle, while the client is listening on its loopback\naddress 127.0.0.1 on pc_right

                                                            \n

                                                            It is the RemoteForward configuration that creates a ssh\ntunnel that is doing the heavy lifting.

                                                            \n
                                                            RemoteForward 127.0.0.1:24800 127.0.0.1:24800
                                                            \n

                                                            It tells the Remote (in this case pc_right ) to listen\nto the port 24800 its loopback address.

                                                            \n

                                                            This is where the client on pc_right will be talking\nto.

                                                            \n

                                                            The ssh connection will then Forward any packets back to the other\nside (in this case pc_middle )

                                                            \n

                                                            And to send to the port 24800 its loopback address.

                                                            \n

                                                            And on that address the server is listening.

                                                            Federated social media can open up some wonderful possibilities to reimagine some of the social apps we already use and find ways to do them better. In this episode I want to highlight a new contender for a Fediverse application that may be able to replace Goodreads. Is it up to the task? We'll look at the pluses and minuses in this episode.

                                                            \n

                                                            This is a psychological experience.

                                                            \n

                                                            When I describe it in full, if you are of any age, you will almost\ncertainly think \"oh yes, that has happened to me.\"

                                                            \n

                                                            For older listeners, the name Baader-Meinhof might be memorable as a\nname given to a group who liked to call themselves the 'Red Army\nFaction.'

                                                            \n

                                                            The name Baader-Meinhof, after two notable members of the group, was\ngiven to it by journalists.

                                                            \n

                                                            In the late sixties, all through the seventies, and even into the\neighties, the Red Army Faction were responsible for a number of\nterrorist attacks in and around East and West Germany. One person's\nterrorist is another person's freedom fighter, but we will not get into\nthat discussion.

                                                            \n

                                                            This psychological phenomenon was given the name, after a man wrote a\nletter to a newspaper in 1994 pointing out that he had recently heard\nthe name, Baader-Meinhof, and thereafter, seemed to hear or see it again\nand again.

                                                            \n

                                                            Following that, many people wrote to the same newspaper making\nsimilar comments, about recently heard names, usually nouns, which were\nthen noticed by them frequently.

                                                            \n

                                                            The phenomenon was also given the name 'Frequency Illusion' in\n2005.

                                                            For many people, public speaking is a very traumatic thing.

                                                            \n

                                                            It is not something that has ever held any great terror for me. That\nis especially true now I am totally blind.

                                                            My Public Speaking Rules

                                                            \n

                                                            These are some rules I live by when public speaking. These apply to\nthings like technical talks or lectures. Not necessarily to after dinner\nspeaking, or the speech you might give as the best man at a wedding.\nThose things are different entirely:

                                                            \n
                                                              \n

                                                            1. NEVER start a talk with an apology for being a bad public\nspeaker. You will be implanting in the audience the subconscious\nsuggestion that they are about to sit through a talk given by a bumbling\nidiot with limited knowledge of the published subject.

                                                              2. \n

                                                            2. Three part rule. A talk about a technical or serious subject\nshould be divided into these three parts

                                                              • the meat of the talk

                                                              \n

                                                              This was given to me a very long time ago by a retired lecturer from\nthe London School of Economics.

                                                              3. \n

                                                            3. The people in the audience wanted to be there. So there is little\nor no hostility in the room. And much empathy.

                                                              4. \n

                                                            4. Don't rush yourself. Pace the talk. Rushing can be a nasty\nfeedback loop which makes your pace increase and your level of\nconfidence plummet.

                                                              5. \n

                                                            5. Don't be afraid of pauses, or silence. These moments can give you\nbreathing space to summarise in your own mind where you are at, whether\nthe last thing you said needs amplification, and what is to come\nnext.

                                                              6. \n

                                                            6. Don't be afraid of the 'ums and erms.' But keep it to a minimum.\nSilence is better than verbal ticks.

                                                              7. \n

                                                            7. Keep humour to a minimum. Depends on the kind of event. If you\nare the best man at a wedding, you are supposed to inject humour,\nprobably at the expense of the groom.

                                                              8. \n

                                                            8. You don't need to pick out one audience member to talk to. You\nare just as effective if you are focused on the back wall. Talking to\njust one member of the audience, particularly if they are right at the\nfront, is probably not a good look. Glancing round the room helps to\nmake everybody feel included.

                                                              9. \n

                                                            Notes

                                                            \n

                                                            I probably broke some of my rules, in particular inserting verbal\nticks early in the podcast. I think I improved focus as I went on.

                                                            \n

                                                            I inserted some humour, including some comments about my family\nChristmas, but then it is, well, Christmas.

                                                            \n

                                                            I am almost never happier than when I am learning new things.

                                                            \n

                                                            I am fiercely proud of, and amazed at the amount of things I know\nabout a lot of subjects. I am a knowledge sponge.

                                                            \n

                                                            The one thing that does make me happier than learning, is sharing\nwhat I know. Which I often do in a tone which suggests I am just amazed\nat the fact I know this stuff at all.

                                                            \n

                                                            Remember, the things you don't yet know are more important than the\nthings you already know. That is true for everybody. So share your\nknowledge in good spirit, keeping arrogance out of the picture.

                                                            \n\n

                                                            In this show we are going to make a punch-card computer out of stuff from your kitchen.

                                                            \n\n

                                                            Most of the materials are things you would otherwise have thrown away.

                                                            \n\n

                                                            What you will need

                                                            \n\n
                                                              \n
                                                            • An empty breakfast cereal box.
                                                              • \n
                                                            • Some bamboo barbecue skewers, eight for an eight bit computer, nine for a nine bit etc. These things come in cheap packs of many skewers. Or you could clean up used skewers.
                                                              • \n
                                                            • Scissors or a sharp craft knife.
                                                              • \n
                                                            • Some glue. Preferably washable PVA glue if you care about your clothes or have a small child 'helping'.
                                                              • \n
                                                            • Some pieces of card which you can write on, the number corresponds to the 'bit-ness' of the computer. If you used eight skewers, you need eight bits of card. These need to be slightly narrower than the cereal box. They could be made from other cereal boxes sliced up. A height of about four inches, ten centimetres is good.
                                                              • \n
                                                            • An enquiring mind and temporarily suspended credulity.
                                                              • \n
                                                            \n\n

                                                            What to do

                                                            \n\n

                                                            Step 1:

                                                            \n\n

                                                            Prepare the case of the computer.

                                                            \n\n

                                                            Cut off the box flaps at the top where the cereal was poured out.

                                                            \n\n

                                                            The computer will eventually be used standing up in the usual position with the open end at the top.

                                                            \n\n

                                                            Step 2:

                                                            \n\n

                                                            Making a chute at the bottom.

                                                            \n\n

                                                            You need to make a sort of chute at the bottom so that stuff that falls down into the box will slide out the front.

                                                            \n\n

                                                            Do this by cutting a horizontal line across the width of the box about four or five inches, about eight centimetres from the bottom edge of the box.

                                                            \n\n

                                                            Now cut down the front edges of the box from the horizontal slit to the bottom.

                                                            \n\n

                                                            This will make a flap that you can fold down by putting your hand inside and pushing it out.

                                                            \n\n

                                                            Hinge it down and make a fold in this flap about half an inch (one centimetre) from the front edge of the flap.

                                                            \n\n

                                                            Coat the inside of the flap, above the fold, with glue. Now push the flap back up and press the folded (gluey) portion of the flap against the inside of the back of the box. You could use some sticky tape to hold it down while it dries.

                                                            \n\n

                                                            When the glue has dried you will be able to see how this now forms a chute at the bottom of the box.

                                                            \n\n

                                                            Step 3:

                                                            \n\n

                                                            Now draw a horizontal line across the front side of the box about an inch, or 2.5 centimetres from the open end.

                                                            \n\n

                                                            Now is the trickiest part because you will need to do some arithmetic. Pity you don't have a computer, right?

                                                            \n\n

                                                            You need to measure out a number of points across this line which correspond to the bit-ness of your computer. So if you are making an eight bit computer, you need eight marks spaced equally across this line, that's nine gaps across.

                                                            \n\n

                                                            When you have done this you are going to pierce holes in the box with either one of the BBQ skewers or something sharper. You need for the skewers to pass right through the box and out the back side, in the same position as accurately as possible. This might be easier if you draw and measure out the same points on the back panel and push holes through from both sides.

                                                            \n\n

                                                            Either way what you are aiming for is to make the path through the box as accurately level and equi-distant as possible. The skewers should pass through the box and remain parallel.

                                                            \n\n

                                                            Step 4:

                                                            \n\n

                                                            We are now going to make the punched cards.

                                                            \n\n

                                                            Create the same number of cards as the bit-ness of your computer. So an eight bit computer will require eight cards.

                                                            \n\n

                                                            The cards will be almost as wide as the inside of the box, and tall enough to write stuff on but not high enough to show their bottom edges through the chute hole at the bottom of the computer. And not so tall that when they fall to the bottom they get wedged between the chute and the back wall of the computer.

                                                            \n\n

                                                            Laying each card flat on the table, draw a horizontal line across the card about\nthe same distance from its top edge as you drew the line into which you punched holes in the body of the computer.

                                                            \n\n

                                                            You will need to measure out the same number of holes across this as the holes across your computer. Again accuracy is important if the computer is to work smoothly.

                                                            \n\n

                                                            Make each hole in the punched cards large enough that the skewers you used pass through the hole with no resistance. A hand-held single hole punch is good for this.

                                                            \n\n

                                                            The holes need to line up when the stack of cards is held flat in a pack.

                                                            \n\n

                                                            Step 5:

                                                            \n\n

                                                            Programming your punched cards.

                                                            \n\n

                                                            Take each card in turn and change all but one of the holes into a slot from the holes to the top of the card.

                                                            \n\n

                                                            For example, for card one, in an eight bit computer, leave hole zero (left-most for little-endian) as it is and for holes 1 to 7 cut from each side of the hole to the top edge, removing the little bit of card.

                                                            \n\n

                                                            So when a card is done it will look a bit like a comb with one hole somewhere along the row, corresponding to which bit the card represents.

                                                            \n\n

                                                            For the next card cut all the holes except the one to the right of the last one.

                                                            \n\n

                                                            When you have done this and placed the cards in a stack, you will see that what you have is a stack of cards, each of which has 1 intact hole and bit-ness minus 1 slots.

                                                            \n\n

                                                            Step 6:

                                                            \n\n

                                                            Loading the program into your computer.

                                                            \n\n

                                                            Holding the cards together in a stack, feed them into the top of the computer, with the punches at the top closest to the open top end of the box.

                                                            \n\n

                                                            Holding the cards in place so that their holes line up with the holes in the box, push skewers through from the front of the box, through the corresponding holes and slots in the stack of cards.

                                                            \n\n

                                                            Now when you stand the computer up, what you have is a box containing a stack of punched cards, each of which is only held in place by one skewer.

                                                            \n\n

                                                            And if you cut the cards to be very close to the width of the box, the cards will sit straight without drooping down at one end.

                                                            \n\n

                                                            Step 7:

                                                            \n\n

                                                            Getting some data out of your computer.

                                                            \n\n

                                                            Before you loaded the cards into the computer, you wrote some data on them, right?

                                                            \n\n

                                                            If you have an eight bit computer and you have eight kids, you will never forget their birthday again. Write the name and birthday of each child on a card and write their name above the skewer hole on the box, using the hole which corresponds to their card, the one with the intact (not a slot) in it.

                                                            \n\n

                                                            When you pull that skewer out, the corresponding card is no longer held in the box, and it drops down and slides out of the chute. Pity it's not quite as much fun as getting nice crisp bank notes out of a cash-machine.

                                                            \n\n

                                                            Finally, take a magic-marker and write 'Windows Vista' on the front of the box. And it might be a good idea to snip off the sharp ends of the bamboo skewers before you put your eye out or damage a small child.

                                                            \n\n

                                                            Troubleshooting

                                                            \n\n

                                                            Problem: When I pull out a skewer, no card drops out.

                                                            \n\n

                                                            Possible causes: There is too much friction between the cards or between the outer edges of the card and the sides of the box. When you load the cards, try to spread them apart a bit. And make the cards a few millimetres narrower than the box. Or the holes and slots in the cards are too small and there is too much friction between the edges of a slot and a skewer.

                                                            \n\n

                                                            Conclusion

                                                            \n\n

                                                            This is a totally pointless activity and you need to get out more.

                                                            \n\n

                                                            I remember seeing this somewhere when I was a very small child. Either in a book or on TV. I think it may have been my slightly older brother who made it. I have the vaguest recollection of a cereal box with some of my mum's knitting needles sticking out.

                                                            \n\n

                                                            If you used eight bamboo skewers, you are now the proud owner of an eight bit computer with eight bits of random access memory.

                                                            \n\n

                                                            A slight drawback is that each time you ask for output (pull out a skewer) the data bit you asked for is no longer inside the computer's memory. So you will have to 'reboot' every five minutes (sound familiar?).

                                                            \n\n

                                                            And because of the way it works, eight bits does not mean 256 different cards.

                                                            \n\n

                                                            But it's fun and a young kid will delight in pulling out a skewer to make a card drop out. There is glue involved as well.

                                                            As a Plasma user, how could I resist.

                                                            \n

                                                            I had previously installed Fedora 36 on the MAC and was receiving\nrandom hardware issues at boot time, I wanted to see if the issue\npersisted on and Arch base, and since I had never used Arch, this was a\nperfect test case.

                                                            \n

                                                            1. The queue of shows is abysmally sparse. There are far more\nopenings for shows in the next few weeks than there are shows\nposted.

                                                            \n

                                                            Alright. Enough preliminaries.

                                                            \n

                                                            A long time ago, at an undisclosed university far, far away, I took\nmy first class about Ethics. One of the things I remember most was the\nquestion of \"Just because you can do a thing, does that mean you should\ndo the thing?\"

                                                            \n

                                                            This was applied to many different scenarios - from nation states\nbuilding weapons of mass destruction, to authoring computer viruses, and\neven to saying what you are thinking at any given moment.

                                                            \n

                                                            It should quickly become obvious that you should not always do a\nthing simply because you can do it. And today, I would like to relate\nthat to DIY home improvement projects, especially as we work our way up\nin years.

                                                            \n

                                                            For regular listeners, you may recall my series \"Everything You\nAlways Wanted to Knox about PEX\" recorded and shared in May through July\nof 2022 (hpr3604, hpr3614, hpr3624 & hpr3634). In\nthis series, I recounted the process of replumbing my home using PEX\nwith helpful advice for anyone else who wants to try it. What I did not\nrealize at the time I was doing the project was the toll that doing so\nmuch work overhead, by myself, was taking on my old shoulder joints. It\nwas only one straw, but a rather significant one, which eventually broke\nthe camel's back. Or, in my case, resulted in several severe tears in my\nrotator cuff and bicep tendon.

                                                            \n

                                                            Therapy was marginally effective, and surgery was eventually required\nto put things back together the way they belonged. My effort to save\nmoney and do the project myself \"Because I could\" helped lead to\nsignificantly more expenses and more than a year of recovery.

                                                            \n

                                                            I am not sharing this for sympathy, but rather because I learned\nsomething important. Now that I am getting older, as I decide which\nprojects I should do myself and which to pay professionals to do, it is\nimportant to factor in the potential impact on my body, my mind and\nthose around me, even if all goes well.

                                                            \n

                                                            Just because you can do a thing does not necessarily mean you should\ndo a thing.

As I mentioned in the previous report on Bookwyrm, it is not unusual to return to an app a few months later and see new features have been added that make it better. In this report I want to highlight three news stories that I think may be of interest.

                                                            The Joule Thief is a delightfully simple circuit that can light an\nLED that requires 2V or more from a battery that is depleted to 1V or\nless. There are three components in addition to the battery and LED: an\nNPN transistor, a resistor and a double wound inductor. The key thing\nabout the inductor is that the same core shares two windings but in\nopposite directions.

                                                            \n

                                                            The explanation of how it works is simple enough, as long as you\nalready understand how inductors and transistors work. In other words,\nit isn't simple at all! In short, the double wound inductor and\ntransistor conspire to generate a transient high voltage spike and so\nturn LED on and off so rapidly that the human eye cannot perceive\nit.

                                                            \n

                                                            The idea of such a circuit is approaching its centenary but the name\nitself is only around 20 years old. I recommend you check out Big Clive's web site as it was\nhe who came up with the name \"Joule Thief\". I also recommend this video in\nwhich he constructs a circuit using some ninja-level soldering\nskills.

                                                            Synopsis

                                                            \n

                                                            The Friday before Christmas, my partner's mother called and asked if I had a short indoor extension cord she could borrow. When I arrived at her house, she showed me her display of ceramic Christmas trees for which she needed the extension cord. These decorations have two pieces. A base which holds a small light bulb, and then the tree which sits over the light and has translucent colored plastic 'Christmas lights' which are illuminated by the light bulb inside the tree. There were four ceramic trees of varying heights—from 14\" (~36 cm) to 6\" (~15 cm) tall. While helping to arrange each of the trees electrical cords and plugging them into the extension cable, one of the trees wouldn't stay lit. If you turned the base or moved the cord it would light back up, but then go out once you took pressure off the cord. I could also hear crackling at times when moving the cord—not a sound you want to hear in an electric ornament.

                                                            \n

                                                            After separating the pieces and turning over the base, I could see not only the sparks, but why it was sparking. At some point, one of wires had come lose from the light socket and was taped back in place with what looks like duct tape. The ornament was made in the 1950s. I'm not sure when the repair was made. It is an ornament that has been passed through the family over the years. The plastic which held the wire in place had failed over the years, and the tape was also failing from the electric sparks that would occur when the wire was moved around. You could see burn marks on the tape around the wire.

                                                            \n

                                                            At first I thought I may be able to fix the side with the bad wiring. Maybe solder the wire onto the socket to give it a good electrical connection, and then use electrical tape to cover the hole where the socket casing had failed, but in the process of taking the wire out and removing all the old duct tape, the socket's electrical contact fell apart. This was for the best, the whole socket needed replacing, but I wasn't sure I could find a replacement socket that would fit through the hole in the ceramic base.

                                                            \n

                                                            While doing my last minute Christmas shopping on Christmas Eve, I stopped at one of the big box hardware stores to browse the electrical section and see if I could find a replacement socket that might work. Of course I hadn't brought either the old socket or the light bulb, but I found a small rack with replacement sockets that looked like it might work. The candelabra style socket replacement looked like the correct size—for both the light bulb and the hole in the base of the ornament.

                                                            \n

                                                            Once I was home, I tested the fit of the light bulb, and the socket was the correct size. It was just a little to big for the hole in the base, but I was hoping I could just grind off some of the raised plastic lettering and maybe a little off the sides of the socket here and there to get it to fit in the base. I was leery of using my Dremel tool to make the hole bigger in the ceramic base. I didn't want it to crack or chip the finish. I ended up doing both. Grinding down some of the plastic on the replacement socket and grinding out the hole in the ceramic base.

                                                            \n

                                                            A bit of electrical tape wrapped around the new socket created a snug fit between the hole in the ornament's base and the socket. I then hot glued the socket to the inside of the base to provide extra stability. Next step was attaching the old cord to the new socket. The cord was in good shape except where it was connected to the old socket. I evened up the end of the cord, then stripped it, and then connected the cord to the new socket with wire nuts.

                                                            \n

                                                            After flipping over the base and screwing in the light bulb, I tested the repair. Success!

                                                            I bought this from Amazon after seeing a video of it on the Big\nClive YouTube channel. It was under £10. This version is no longer\navailable but there is a version 2 for a similar price. I haven’t tried\nthis one.

                                                            \n

                                                            The Nitecore Tube is a small plastic-bodied torch with fittings for a\nkey ring. I have not been keen to keep it on my keyring for fear of\ndamage from the keys, so I keep it always in my shirt pocket.

                                                            \n

                                                            The torch is controlled through a rubber-like button on one side, and\nhas a micro USB port on the edge which is covered by a rubber cap.

                                                            \n

                                                            While charging, a blue LED can be seen inside the body of the torch,\nwhich turns off when the charging process is complete.

                                                            \n

                                                            The torch can operate at a number of brightness levels and has a\nlock mode:

                                                            I don’t use this torch a huge amount. The fact that it’s always in my\npocket means I have a source of quite bright light when I need one. The\nlower level light is useful for moving around in the dark or in a gloomy\nplace. The brighter level I tend to use to read labels on jars, bottles\nand other containers. For some reason, these labels are often designed\nwith minimal contrast (like a dull orange lettering on a purple\nbackground) which my eyes just can’t cope with. The Nitecore is my\nsaviour with this sort of stuff!

                                                            I don’t charge it very often, but it is easy to do it with a phone\ncharger - I have several micro USB cables around, so it’s no\nproblem.

                                                            This is a great little device. I have other torches for when I need a\nstronger, more broadly illuminating light source. I wouldn’t be carrying\nany of these around with me though. The Nitecore is small and compact\nenough that I can keep it on me all the time.

                                                            I discuss dependent types, which are types that can contain non-type\nprograms. An example of a dependent type is a list whose type contains\nits length. Instead of just writing List<String> for\na list that contains strings, dependent types include types like\nList<String, 5> that describe lists of exactly five\nstrings. Dependent types can also be used to represent mathematics, in\nwhich case the programs that they describe count as proofs, and tools\nfrom programming can be used to write math.

                                                            \n

                                                            Dependent types used to be something that really required a research\nbackground, but there has been a lot of progress on making them more\nuser-friendly and on writing accessible introductions lately.

                                                            Notes: Forgot to mention that I hot glued the top lid (original lid\nfor the 'speaker box'), on top of the boards. I had used the device with\nthe top uncovered for a month because I hoped I would find a better\nchoice but after getting tired of the wires detaching and worrying about\nthe sdcard slot getting wrecked I decided to commit to glueing the lid\non.

                                                            The boards are very robust, I dropped them in the snow a few times.\nThey would stop working but after drying off would function.

                                                            I didn't find the datasheet with the resistance values for other\nvalues until after I glued the lid so will have to open it up again or\nget into one of the switch lines and do resistor combinations... now\nthat I know more I think I should be able to control the mp3 player with\none analog output pin from the arduino for all the functions, since it\nseems the pin 8 that all the switch resistors lead to detects voltage\nlevels from the voltage divider created when one of the switches goes to\nground.

                                                            In the early days of computing, the computing power was kept in centralized large mainframes and users would connect to them via so called \"dumb\" terminals. These often provided their output through a printer and continuous feed of paper. However in 1964 UNIVAC introduced the Uniscope 300, which was one of the first terminals to provide a video monitor for display. With the introduction of this system came the introduction of several concepts that we take for granted today and they are described during the reading of this brochure.

                                                            As I mention in the episode, $15,000 USD in 1964 is worth considerably more today, according to an online inflation calculator it is now worth approximately $144,000 today. So even if that was for 48 terminals as it seems to mention in the hand written note, that might equate to about $3000 per terminal in 2023 dollars.

                                                            Remapping Mouse Buttons with XBindKeys on Linux

                                                            After a really long time of not bothering to figure out how to do this, I finally did some research and found out how to remap the extra buttons on my Kensington Expert mouse and my Logitech marble trackball mouse in a Linux environment. The tools it needed were xvkbd, xdotool, and xbindkeys. I already had the first two installed, but had never used xbindkeys before. I also used xev to identify the button numbers and key numbers.

                                                            \n\n

                                                            The Kensington Expert Mouse is one that I've had for about 15 years, and it was fairly expensive when I bought it, something like $75 or $80. It has four large buttons with a large trackball in the middle and a scroll wheel going around the track ball. I bought it at a time when I was doing a lot of graphic work that required clicking and dragging and double-clicking and stuff like that. If you're using it in a Mac or Windows environment, there is a special configuration tool that you can use to set it up just how you want. I had always configured it so that the upper left and upper right buttons were used for double-clicking and click dragging. This helped reduce a lot of strain on my hands. I have never gotten this to work on Linux, though, until today.

                                                            \n\n

                                                            If you want to do this yourself, the first thing to do is make sure you have these packages installed: xvkbd, xdotool, and xbindkeys.

                                                            \n\nThen create a configuration file in your home directory:\n\n
                                                            \n~/.xbindkeysrc\n
                                                            \n\nIn order to map the upper left button to \"double click,\" and the upper right button to \"click and drag,\" I added these lines to the configuration file:\n\n
                                                            \n# Double-click assigned to button 2 (upper left)\n\n\"xdotool sleep 0.2 click 1 ; xdotool click 1\"\n      b:2\n\n# Click and Drag assigned to button 8 (upper right)\n\n\"xdotool sleep 0.2 mousedown 1\"\n      b:8\n
                                                            \n\nTo test the settings, simply kill the xbindkeys process and restart it by typing xbindkeys:\n\n
                                                            \nuser@hostname:~$ pkill -f xbindkeys\nuser@hostname:~$ xbindkeys\n
                                                            \n\n\n

                                                            On my desktop computer I have a Logitech marble trackball mouse, and it has two small keys that are assigned to back and forward by default. This can be handy for navigating file managers and web pages, but I wanted them to be assigned to \"page up\" and \"page down\" (to make up for the lack of a scroll wheel on the mouse). Here is the configuration file for that machine:

                                                            \n\n
                                                            \n\"xvkbd  -text \"\\[Page_Down]\"\"\n       b:8\n\n\"xvkbd  -text \"\\[Page_Up]\"\"\n       b:9\n
                                                            \n\n

                                                            I suppose I could have used xdotool for this configuration file as well, but for reasons I can't remember now, I tried xvkbd first and it worked, so I did not experiment further. I used xdotool for the Kensington because xvkbd did not have a way to perform virtual mouse clicks.

                                                            Upon arrival, I was required to quarantine for 3 days as well as take a home test (referred to as RAT: Rapid Antigen Test, by the locals) every day for the first 7 days

                                                            On the third day I received my PCR and RAT tests as Covid Positive.

                                                            By law I was now required to quarantine in my hotel until I tested negative on 2 consecutive days. Since my symptoms were very mild, a sniffle and low grade temp, merely 2-3 deg above normal, I could stay in the hotel and was not required to\ntransfer to a public health center.

                                                            I was also required to register the positive results with a government website. This registration kicked off a series of events, including a visit from a health representative. (he stood in the hall, I was not permitted to leave the room) I was Required to install an app on my phone called "Stay Home Safe'' and to wear a wristband that I presume was a GPS and possibly temp/pulse tracking device that connected to my phone by bluetooth. The agent installed the app, and synced the watch to it.\n

                                                            GitLab always deploys your website from a specific folder called\npublic in your repository. To deploy your site, GitLab uses its built-in\ntool called GitLab CI/CD to build your site and publish it to the GitLab\nPages server. The sequence of scripts that GitLab CI/CD runs to\naccomplish this task is created from a file named .gitlab-ci.yml, which\nyou can create and modify. A specific job called pages in the\nconfiguration file makes GitLab aware that you're deploying a GitLab\nPages website.

In computer security, an attack vector is a\nspecific path, method, or scenario that can be exploited to break into\nan IT system, thus compromising its security. The term was derived from\nthe corresponding notion of vector in biology. An attack vector may be\nexploited manually, automatically, or through a combination of manual\nand automatic activity.

                                                              • In computer networking, port forwarding or port mapping is an\napplication of network address translation (NAT) that redirects a\ncommunication request from one address and port number combination to\nanother while the packets are traversing a network gateway, such as a\nrouter or firewall. This technique is most commonly used to make\nservices on a host residing on a protected or masqueraded (internal)\nnetwork available to hosts on the opposite side of the gateway (external\nnetwork), by remapping the destination IP address and port number of the\ncommunication to an internal host.

                                                            In our 14th Software Freedom Podcast episode Matthias Kirschner talks with our guest, Elektra Wagenrad, about the origins of Freifunk, the B.A.T.M.A.N. protocol, and the Mesh Potato project. If you are new to the world of mesh networking this episodes is an easy entrance to it. Elektra not only explains the theory behind the protocols but also dives deeper into the philosophical idea of it. In this context, Matthias and Elektra also touch on the difficult topic of limiting the use of Free Software, using the example of the former ban on the use of the B.A.T.M.A.N. protocol for military activities. Last but not least they also discuss the EU’s Radio Equipment Directive and the FSFE's Router Freedom activity.

                                                            I like the idea that there are tools available to enhance the\n'cd' command, remembering places you have been in the file\nsystem and taking you there easily.

                                                            I was using 'autojump' for a while last year, but didn’t\nreally get on with it. This was mainly because there was no way of\nexcluding certain directories which had been visited from its list.

                                                            zoxide is a smarter cd command, inspired by z1 and\nautojump.

                                                            It remembers which directories you use most frequently, so you can\n“jump” to them in just a few keystrokes. zoxide works on all major\nshells.

                                                            What does it do?

                                                            • It offers the functionality of the Linux/Unix 'cd'\ncommand.

                                                            • It collects the directories you have visited into a database and\ngives them a ranking relating to the number of times they have been\nvisited. It applies aging rules and removes these when the ranking drops\nbelow one. It uses frecency to do this - a combination of\nfrequency and recency. (See the Wikipedia page\nexplaining this word)

                                                            • It performs algorithmic matching on the directory you specify and\ntakes you to the highest ranking best match.

                                                            • It “knows” where it is (in the Bash shell) by calling a function\nout of the PROMPT_COMMAND variable. This can be used to\nexecute one or more commands before displaying the prompt for a new\ncommand. This is a common way to hook monitoring commands into\na Bash session.

                                                            Where can you get it?

                                                            \n

                                                            I installed it from the Debian Testing repo, but I got\n'zoxide v0.4.3-unknown' whereas the latest version is\n0.9.0. Installing from the GitHub page seems the\nbest option if you want the latest version.

                                                            \n

                                                            There is an installation script on the GitHub page and it’s possible\nto download it with curl and pipe it to Bash. I’m never\ncomfortable doing this, but that’s your choice.

                                                            \n

                                                            I also installed fzf from the Debian Testing repo,\nthough I’m still learning what this can do, since it’s very rich in\nfeatures!

                                                            \n

                                                            How do you set it up?

                                                            \n

                                                            This process is shell-specific. I run Bash so I have added it to my\n~/.bashrc and the command there is:

                                                            \n
                                                            eval "$(zoxide init bash)"
                                                            \n

                                                            What this does is generate a number of Bash functions and aliases and\nsome commands which are fed into eval and executed in the\ncurrent context.

                                                            \n

                                                            Function z is created which gives a way of invoking\nzoxide in fewer keystrokes, though the full functionality\nof zoxide is not available through this function, use the\nfull zoxide command.

                                                            \n

                                                            Function zi lists all of the stored directories courtesy\nof fzf. I haven’t tested this without fzf, so\nI’m not sure what it does if it’s not available. The scrollable list can\nbe navigated and a directory chosen with the Enter key (or\ndouble mouse click). In the scrollable list, if characters are typed\nthey are used to select directories from the list, so that it’s simple\nto find a directory whose exact name you have forgotten.

                                                            How to tune it?

                                                            \n

                                                            The zoxide behaviour can be modified through environment\nvariables (and at setup time).

                                                            \n

                                                            For example it is possible to define directories which are not to be\nstored using the environment variable _ZO_EXCLUDE_DIRS.\nThis must be done before running zoxide init. In my case, I\nhave the following in my ~/.bashrc:

                                                            \n
                                                            export _ZO_EXCLUDE_DIRS="/media/extras:/media/extras/*"\neval "$(zoxide init bash)"
                                                            \n

                                                            The setup details are to be found in the GitHub documentation.

                                                            \n

                                                            Conclusion

                                                            \n

                                                            I really like this. It’s fast and configurable, and with\nfzf gives some great command-line features. There are\neditor plugins, such as zoxide.vim for Vim and Neovim (not\nused yet). It also integrates with other third-party tools.

                                                            \n

                                                            It seems to be the best of its type!

                                                            The hole needs to be as close to the exact dead-centre of the plate as you can make it.

                                                            \n\n

                                                            Here in the UK it is possible to obtain a hole punch called a Q-Max punch from Maplin, the supplier of electronic and hobby parts.

                                                            It is very important that this hole is:

                                                              \n
                                                            • As close to the centre of the end-plate as is humanly possible
                                                              • \n
                                                            • Has edges which are clean and crisp. Hence the use of a hole punch.
                                                              • \n
                                                            \n\n

                                                            It is these two factors more than any other that will effect the efficiency of the cannon.

                                                            \n\n

                                                            Step 2:

                                                            \n\n

                                                            Cut off the mouth-piece end of the balloon.

                                                            \n\n

                                                            Stretch it over the open end of the Pringles can and pull it as tight over the end as you can.

                                                            \n\n

                                                            When I say the open end I mean the end from which you removed the lid and chomped on the chips.

                                                            \n\n

                                                            Use the parcel tape to wrap the balloon tightly around the circumference of the cylinder, anchoring it in position so that the open end of the can is now like a drum formed by the stretchy membrane of the balloon. Nice and tight.

                                                            \n\n

                                                            The cannon is now ready to fire.

                                                            \n\n

                                                            Firing the cannon

                                                            \n\n

                                                            Pinch the centre of the balloon membrane and pull it back as far as you can. This might be easier if you push some kind of (blunt ended) rod into the can from the hole end and push out the membrane until you can pinch it.

                                                            \n\n

                                                            Some other stretchy latex device which has a little bulb at the end might be easier to get hold of, but I can't think of such an item, can you?

                                                            \n\n

                                                            When you let go of the membrane with it stretched out as far as you can go, what happens?

                                                            \n\n

                                                            Well, if you made the small circular hole at the metal-plate end of the cylinder nice and clean and central, the cannon fires a coherent vortex of air.

                                                            \n\n

                                                            What do I mean by a 'vortex'?

                                                            \n\n

                                                            Imagin a ring doughnut compromised of air shooting out of the end of the tube like a smoke ring out of a Hobbit.

                                                            \n\n

                                                            The vortex is spinning. Not like the bullet fired from a rifled barrel, but as if it is constantly trying to turn itself inside-out.

                                                            \n\n

                                                            This spinning keeps the torus (this is what the shape of a ring doughnut is called) coherent and intact for several feet.

                                                            \n\n

                                                            If you made the hole in the metal plate end of the tube nice and clean, and you stretched the balloon membrane out as far as you possibly can, the cannon is capable of blowing out the flame of a candle at about ten feet (three metres) in the still air in a room.

                                                            \n\n

                                                            As soon as it leaves the cannon, the vortex will begin to degrade and fall apart.

                                                            \n\n

                                                            A word of warning

                                                            \n\n

                                                            This little toy might only be firing a torus of air, but do not be tempted to shoot yourself or the cat in the face at point blank range. It hurts.

                                                            \n\n

To make the recording I used the Hi-Q mp3 recorder app on my Android device. In the end I didn't do anything in post-production to adjust the volume or compression of the audio. It turned out pretty well "as is."

                                                            • make sure you start this with a \"fresh\" tmux instance

                                                            • symlink the last file to the desired save file: $\nln -sf <file_name> last

                                                            This is the definition of Unicode on Wikipedia:

                                                            Unicode, formally The Unicode Standard, is an information technology\nstandard for the consistent encoding, representation, and handling of\ntext expressed in most of the world's writing systems. The standard,\nwhich is maintained by the Unicode Consortium, defines as of the current\nversion (15.0) 149,186 characters covering 161 modern and historic\nscripts, as well as symbols, thousands of emoji (including in colors),\nand non-visual control and formatting codes.

                                                            \n

                                                            Hello and Welcome hacker public radio audience my name is … and\nwelcome to this podcast.

                                                            \n

                                                            As usual I'd like to thank the people at HPR for making this service\navailable to us all on these here inter-tubes. Hacker Public Radio is a\ncommunity led podcast provided by the community for the community. That\nmeans you can contribute too.

                                                            \n

                                                            In this episode I decided to see if I could get get ChatGPT to write\nan HPR episode about itself. I was initially reluctant to do this.\nHowever, since HPR was recently short on shows and I was rather short on\ntime and ideas I decided to give it a go.

                                                            \n

                                                            One reason for my reluctance was that I didn't want HPR to be flooded\nwith shows generated by ChatGPT. The other reason being that a great\nshow covering ChatGPT was previously provided by the hpr host \"dnt\"\nentitled \"Chatbot hallucination\". Refer to 3803 https://hackerpublicradio.org/eps.php?id=3803.\nIn comparison, my poor attempt took about 10 minutes to generate while I\nwas waiting to be called for lunch.

                                                            \n

                                                            Below are the steps I used to generate the prompt to generate a show\nfor HPR.

                                                            \n

                                                            You interface with ChatGPT by providing it prompts. This just means\ntyping some text into the input field within the ChatGPT website.

                                                            \n

                                                            The steps I used\nto produce the ChatGPT prompt

                                                            \n

                                                            Here is how I did it. Keep in mind that the complete process took\njust 10 minutes.

                                                            A solar flare is a huge release of energy at and near the surface of the Sun in the form of electromagnetic radiation and fast particles. On 19 January 2023 at around 11:00 UTC I was lucky enough to see a solar flare with my own eyes using a Coronado PST Solar Telescope that belongs to the Astronomical Society of Glasgow.

Some of the services for which the companies charge\nfees, such as sending the perpetrators cease and desist orders, make\nvictims feel better but are not legally enforceable. The companies may\nalso attempt to discourage victims from reporting the sextortion to law\nenforcement. Limited reporting indicates the companies are directly or\nindirectly involved in the sextortion activity.

Criminals tell victims they are suspects in\nfinancial crimes and threaten them with arrest or violence if they do\nnot pay the criminals. Criminals exploit widely publicized efforts by\nthe People’s Republic of China government to harass and facilitate\nrepatriation of individuals living in the United States to build\nplausibility for their fraud. Criminals typically call victims,\nsometimes using spoofed numbers to appear as if the call is from the\nChinese Ministry of Public Security, one of its localized Public\nSecurity Bureaus, or a US-based Chinese Consulate. Criminals may also\ncommunicate through online applications.

Since\nChat GPT learns from existing text, it may pick up biases or\ninaccuracies that exist in the data it is trained on. Additionally,\nthere is a risk that Chat GPT may generate inappropriate or offensive\nresponses if it is not properly monitored.

                                                            Chat GPT has already been used in a variety of industries and fields,\nbut there is still a lot of potential for future applications. For\nexample, it could be used to power virtual assistants that are even more\nintelligent and personalized than current offerings. It could also be\nused to generate more sophisticated chatbots that can assist with\ncomplex tasks.

                                                            Common Misconceptions and\nConcerns

                                                            \n

                                                            One common misconception about Chat GPT is that it is a threat to\nhuman jobs. While it is true that Chat GPT can automate certain tasks,\nit is unlikely to replace humans entirely. Instead, it is more likely to\naugment human abilities and make certain tasks more efficient.

                                                            \n

                                                            Another concern is the ethical implications of using AI language\nmodels like Chat GPT. It is important to ensure that the data used to\ntrain Chat GPT is diverse and free of biases. Additionally, it is\nimportant to ensure that Chat GPT is used responsibly and not used to\nspread misinformation or harm individuals.

                                                            \n

                                                            Chat GPT is a powerful tool that has the potential to revolutionize\ncustomer service, content creation, and chatbots. While there are some\nlimitations and concerns associated with its use, the benefits of using\nChat GPT are clear. As the technology continues to evolve, it is\nimportant to consider the ethical implications and ensure that it is\nused responsibly.

                                                            Hello, my name is André Jaenisch. You can find myself online under\nRyuno-Ki as well.

                                                            \n

                                                            This is my first episode on Hacker Public Radio!

                                                            Today I want to introduce myself.
                                                            \nI'm a web developer for ten years now and recently turned into a\nfreelancer.
                                                            \nMy area of expertise is with Frontend technologies, although I also know\nNode.js and Python. I taught myself these languages because my studies\nin mathematics did not cover them.
                                                            \nDuring my studies I switched to GNU/Linux. I started with Ubuntu but\ndiscovered that I prefer Rolling Release distributions more. So I jumped\nto Sabayon Linux which was based on Gentoo back then but pre-compiled\nthe binaries while staying compatible. Now they decided to turn into\nanother direction so I was looking for another home. I tried Gecko Linux\nbased on openSUSE for a while until they had bad news in the press. I'm\ncurrently running Kaisen Linux which is based on Debian Bookworm.

                                                            \n

                                                            Speaking of, I love to read. I have whole shelves filled with books\nhere.
                                                            \nThere is so much to learn from books even in the age of the Internet. I\nenjoy that they have a finite amount of content you can walk\nthrough.

                                                            \n

                                                            I learned about Hacker Public Radio at FOSDEM 2023. When I mentioned\nthat I have a RODE NT-USB microphone at home already I was encouraged to\ncontribute to the show. Now I have been listening to the podcast since\nthe beginning of the year and already heard some of the emergency shows.\nI noticed that the hackers on the show are mainly from the United\nStates. I hope you welcome people from other parts of the world as\nwell.

                                                            \n

                                                            I'm from Germany in Europe. A beautiful place to live and I bet as\ndiverse as in the States when it comes to the landscape. We have more\nthan Berlin and Bavaria here!

                                                            \n

                                                            I'm not quite sure what kind of content you would love to hear about.\nI have the requested topics page in front of me and could talk about\ndifferent items. For example, my first smartphone ever was a Firefox OS\n(I still have it. As well as a tablet).
                                                            \nI switched to Android with F-Droid when Mozilla was cancelling the\nproject. I'm running on a Fairphone here, which is a small Dutch\nmanufacturer that already managed to move the whole industry into a more\nsustainable direction. Because we produce lots of waste. So I could talk\nabout that.

                                                            \n

                                                            Or I could talk about building things for the web. Usually I blog\nabout that because I feel like text feels more natural to it. But then I\nsaw that some episodes contained code snippets in the show notes.

                                                            \n

                                                            I could talk about mathematics. We don't have enough podcasts about\nmath! My focus was on statistics and numerics so that might be\ninteresting?

                                                            \n

                                                            What I would love to hear more about is music theory. You see I\nhaven't learned to play an instrument in my life. Mainly because those\nare expensive. My personal taste goes more into heavy metal but I'm not\nsure whether you would call me a fan. What does make a metalhead anyway?\nBut in order to improve my game development having some sort of music\nand sound effects is important. So I was really enjoying the episode\n3792 on reading music sheets. I lend some books on the library to learn\nmore. These subjects weren't covered in depth in my school days!

                                                            \n

                                                            Another subject I would like to learn more about is electronics.\nEspecially repairing one's computers. Look, I'm using ThinkPads since\nyears now. I have a X250 (from FOSDEM) in current use. But I also have a\nX200 and a T520 gathering dust here. Mainly because something „broke”\nwith the hardware and I'm too afraid to crack them open.
                                                            \nThen there's a HP Pavilion standing under my desk to wait for repair.\nAnd even one of the old machines from the DOS era with an original\nLemmings installed! But I have no idea how to refurbish them into a\nbootable state. Do you have ideas?

                                                            \n

                                                            I'm sharing my homepage as well as\nmy e-mail address in\nthe show notes. I would really love to hear back from you.

                                                            \n

                                                            I feel like I already touched on different ideas today, but looking\nat the time the recording is rather short. Personally I can tune into\nepisodes up to 30 minutes best, so I will try to respect this threshold\nmyself.

Lourenco used the 23 credit cards to make more than $423,000 in\nunauthorized purchases. He also used the debit card for a joint bank\naccount belonging to two of the victims to make an additional $57,000 in\nunauthorized charges. Lourenco admitted that he knew at least one of his\nvictims was a vulnerable victim when he used the victim’s identity to\ncommit his crime.

                                                            Hello again, my name is André Jaenisch, also known as Ryuno-Ki.

                                                            \n

                                                            Last week I recorded my first episode for Hacker Public Radio, the\npodcast you are listening to right now. This one is recorded on 15th May\n2023. Again I'm publishing it under a Creative Commons Attribution\nShare-Alike 4.0 International License.

                                                            \n

                                                            I was surprised to get mentioned on the Fediverse after submitting my\nshow. You can find me there at RyunoKi@layer8.space (no dash, eight as\ndigit, link in the shownotes) in case you want to reach out to me.

                                                            \n

                                                            I'm also delighted to have received an email even before my last\nepisode was airing. I was asked whether I am interested in recording an\nepisode on my experience with contributing to Hacker Public Radio for\nthe first time. So this is going to be the topic for today. As a warning\nupfront: I have a reputation of overthinking stuff. I blame my\nneurodiversity for it. That being said I'm positive that sharing my\nthought process can help make the service better for everyone.

                                                            About recording software

                                                            \n

                                                            I'm recording this episode again using Audacity. Now there is choice\nabout which software you can use for a podcast. Online based as well as\noffline one. Audacity was in the news for sending analytics home.\nHowever I couldn't find any indication in the settings for it (to\nopt-out). The forks of the software weren't packaged up for Debian as\nfar as I could tell. Or perhaps they require an additional sources.list\nentry, I don't know.

                                                            \n

                                                            Before recording my very first podcast here I had only experience\nwith some video recording. Oftentimes done by the host but I also\nprepared a few videos for an online course (which I couldn't publish\nbecause life happened) and talks I gave during the pandemic years.

                                                            \n

                                                            Learning about how to\npodcast

                                                            \n

                                                            As I often do when I enter a new subject, I went to the library and\ngrabbed some books to learn more. In particular I lended Podcasts by\nDirk Hildebrand. A small\nbook in German published at Haufe. I add a link in the\nshownotes.

                                                            \n

                                                            Reading through it I learned that I'm doing okay. It's really easy to\nstart a podcast as HPR promises! The thing I should spend some attention\non is keeping a consistent distance to the microphone, enable some level\nof feedback during the recording so that I can listen to what is\nrecorded while speaking (using my gaming headset Logitech G230) and\nprepare a script.

                                                            \n

                                                            I don't have to think about designing images for the show or episode\nbecause HPR will take care of that for me. It might be different if I\nstart my own podcast. Perhaps using Funkwhale or Castopod. Right now I'm not taking\nsteps towards that. Mainly because I need to rent some webspace first.\nIn my experience streaming media takes considerable amount of bandwidth.\nPair that with hosters that try hard to convince you to buy your domains\nwith them as well and the choice shrinks. I have my DNS provider\nalready, thank you very much.

                                                            \n

                                                            Adapting lessons learned

                                                            \n

                                                            I looked into how to do that in Audacity and I think the best I could\ndo for now is hitting on the microphone icon next to the meters in the\nupper right of the interface and enable observation before I start\nrecording. Also leaving a little bit of time before and after the\nrecording allows me to cut keyboard clicks for starting and stopping the\nrecording. In HPR 3802 I also learned about skipping silences which is a\nEffect in the Special category here. I hope I don't have pauses so long\nthat it warrants to truncate them.

                                                            \n

                                                            My main thought about going with Audacity was post-processing\ndirectly after the recording. I learned from my talks that I already\nfeel comfortable with a script in front of me. It gives me the security\nI need to avoid too many ums.

                                                            \n

                                                            What's missing on HPR

                                                            \n

                                                            However, I feel like a few things are missing. Considering that this\nis a podcast that is distributed through HPR and its partners I would\nlike to have chapter markers. I couldn't find a hint on how to add them\nin the form I was presented. Using timestamps it allows to easily see\nthe outline of a recording which aids in the decision making process on\nwhether it's worth the time to listen to a particular episode. I hope\nyou consider the episodes here useful to make time for them :) Thank\nyou.

                                                            \n

                                                            Another question mark I had when preparing the recording were the\nsettings. I'm used to have a guideline when recording videos for an\nonline talk. Things like preferred format and container, to technical\ndetails like stereo or mono to the sampling rate (value and whether\nstatic or variable). The only thing I found is a hint that submissions\nwill be transcoded to mono. I record in stereo with the default 44,1 kHz\nsampling rate here. There was no recommendations on the format so I went\nwith OGG Vorbis instead of MP3 because of license freedom. Audacity\nappear to not support FLAC so I have to use a lossy format. It's true\nthat MP3 enjoys wide support, but I want to encourage freedom when given\nthe choice. I could have chosen WAV files but those tend to become huge\nreally fast.

                                                            \n

                                                            Adding metadata

                                                            \n

                                                            Now I also add metadata to the recording. Vorbis offers comments for\nthat. You can compare it to ID3 tags for MP3 files. Given that I\ncouldn't find a way to enter these chapter information in HPR web forms\nI'm experimenting with EasyTAG from the debian repository. From reading\nthe source code of my podcatcher of choice (AntennaPod for Android as\ndistributed in the F-Droid app store) I can tell that it parses these\ncomments at least. If that doesn't yield results I hope to see, there is\nvorbiscomment of the vorbis-tools package for the command line. And Kid3\nwith a Qt or CLI interface. Expect some slightly different metadata by\nme over the course of my contributions.

                                                            Last thing I want to highlight before ending this episode is\nshownotes. Now I have more experience with blogging than recording a\npodcast. When researching recommendations online there is all this SEO\nfluff that goes into writing subtitles. Usually with catchy titles,\nclickbait and all the rest. I have opinions here. However, I enjoy that\nthere is no „leave a rating and a review” part in the episodes I\nlistened to so far, because a podcast is a special RSS feed basically.\nWhy would I want to bind myself to a special platform? But then I also\nwant to be able to read up and search through the content of a podcast\nepisode. Right now I'm sharing my prepared script as a shownote. It\ncould come off as a wall of text. I'm open to feedback on this front.\nYou can find my Keyoxide profile below. Please do reach out to me.

FIPS standards establish requirements for ensuring computer\nsecurity and interoperability, and are intended for cases in which\nsuitable industry standards do not already exist. Many FIPS\nspecifications are modified versions of standards the technical\ncommunities use, such as the American National Standards Institute\n(ANSI), the Institute of Electrical and Electronics Engineers (IEEE),\nand the International Organization for Standardization (ISO).

These standards and\nguidelines are developed when there are no acceptable industry standards\nor solutions for a particular government requirement. Although FIPS are\ndeveloped for use by the federal government, many in the private sector\nvoluntarily use these standards.

Many good pull requests were never merged\nand the original project is missing some features which users can expect\nfrom a modern password manager. Hence, we decided to fork KeePassX to\ncontinue its development and provide you with everything you love about\nKeePassX plus many new features and bugfixes.

However, it is written in C# and\ntherefore requires Microsoft's .NET platform. On systems other than\nWindows, you can run KeePass using the Mono runtime libraries, but you\nwon't get the native look and feel which you are used to.

                                                              • Cloud synchronization with Dropbox, Google Drive, OneDrive,\nownCloud, Nextcloud etc. can be easily accomplished by simply storing\nyour KeePassXC database inside your shared cloud folder and letting your\ndesktop synchronization client do the rest. We prefer this approach,\nbecause it is simple, not tied to a specific cloud provider and keeps\nthe complexity of our code low.

                                                              • Yes. But only if you store them in the same database as your\npassword. We believe that storing both together can still be more secure\nthan not using 2FA at all, but to maximize the security gain from using\n2FA, you should always store TOTP secrets in a separate database,\nsecured with a different password, possibly even on a different\ncomputer.

                                                            A kitchen experiment to demonstrate the power of condensing steam

                                                            \n\n

                                                            What do you think about when you consider how a steam engine works?

                                                            \n\n

                                                            Well you probably think about a fire used to heat water in a pressure vessel to form super-heated steam.

                                                            \n\n

                                                            Then that steam is injected into cylinders in a controlled and sequenced manner to push a piston up the length of the cylinder. Piston rods and cranks are used to change the linear motion into rotary motion to drive wheels or gears.

                                                            \n\n

                                                            Inertia causes the rotary motion, through the same cranks and rods, to expel the spent steam from the cylinder, before the whole cycle begins again.

                                                            \n\n

                                                            But that's only half the story.

                                                            \n\n

                                                            Steam engines also use the power of a partial vacuum created by condensing steam to produce linear motion in the same way, or to suck the hot products of combustion from the fire through pipes which pass through the pressure-vessel and heat the water.

                                                            \n\n

                                                            What you will need for the experiment

                                                            \n\n
                                                              \n
                                                            1. An empty drinks can, such as a 330ml soda can.
                                                              2. \n
                                                            2. A shallow container, such as a baking tray.
                                                              3. \n
                                                            3. A pair of barbecue tongs or kitchen tongs with which you will be able to grasp a hot can without burning your hand or getting too close to the heat.
                                                              4. \n
                                                            4. A source of heat, the cooker top in the kitchen is ideal.
                                                              5. \n
                                                            \n\n

                                                            How to do it

                                                            \n\n

                                                            Step 1:

                                                            \n\n

                                                            Thoroughly wash out the empty can. Any sugary residue might burn and smell.

                                                            \n\n

                                                            Put about a centimetre (half an inch) of water into the can. Enough to cover the centre of the concave end of the can inside.

                                                            \n\n

                                                            Step 2:

                                                            \n\n

                                                            Place your shallow container next to your source of heat. This will most probably be a baking tray on the kitchen worktop next to the cooker where you will heat your can.

                                                            \n\n

                                                            Put about a centimetre (half an inch) of cool water in the tray.

                                                            \n\n

                                                            Step 3:

                                                            \n\n

                                                            Place your can on the heat. It will quickly begin to boil because it only contains a small amount of water.

                                                            \n\n

                                                            Wait until the water is really boiling and filling the can with steam.

                                                            \n\n

                                                            Grasp the can with the tongs. You need to do this in an underhand grip which will allow you to, in one swift and smooth motion, remove the can from the heat, turn it over and plunge the open end into the cool water in the tray.

                                                            \n\n

                                                            Do exactly that. As swiftly and smoothly as you can.

                                                            \n\n

                                                            Here you will see the need for a vessel like a baking tray, the larger target makes the quick and smooth transfer of the can from the heat to the condensing cool water easier.

                                                            \n\n

                                                            What happens?

                                                            \n\n

                                                            The can is full of steam, which will instantly condense when the open end of the can is plunged into the cool water.

                                                            \n\n

                                                            Bam!

                                                            \n\n

                                                            The partial vacuum created in the can will cause it to be very quickly and impressively crushed.

                                                            \n\n

                                                            The power of a partial vacuum is far easier to harness and is more powerful than pushing a piston along a cylinder with pressurised steam.

                                                            \n\n

                                                            The mechanism of an efficient steam engine will inject pressurised steam into a cylinder during the phase of motion where the piston is pushed up the length of the cylinder, and inject a small amount of cold water into the cylinder fractionally after the full travel of the piston and as it is just beginning the return stroke. In this way the cylinder is both pushed and pulled up and down the cylinder.

                                                            \n\n

                                                            But the condensing part of the cycle is far more efficient at pulling the piston than the steam injection phase is at pushing it.

                                                            \n\n

                                                            The dramatic 'chugging' of a steam engine as it pulls away from a station is the part of the sequence in which condensing steam is used to create a partial vacuum in the smoke-box at the front of the engine. The hot products of combustion are drawn by this partial vacuum from the fire at the far end of the engine, through the pipes which pass through the boiler, increasing the efficiency of the heating of the water. The same partial vacuum is also used to increase the draft of air into the furnace.

                                                            \n\n

                                                            It is mostly the rush of clean air into the furnace, drawn by the partial vacuum, which gives rise to the deep and pleasing heart-beat of a big powerful engine as it works hard to move a heavy train from a standing start.

                                                            \n\n

                                                            I always find that confusing, so for me it's a lot easier to see what\nis going on by creating some example files.

                                                            \n

                                                            First let's create some test files by echoing the number 1 and the\nnumber 2 into a file called 1and2.txt

                                                            \n
                                                            [host@hpr]$ echo "1" > 1and2.txt\n[host@hpr]$ echo "2" >> 1and2.txt
                                                            \n

                                                            And let's create another one with the value 2 and 3 and we'll call it\n2and3.txt

                                                            \n
                                                            [host@hpr]$ echo "2" > 2and3.txt\n[host@hpr]$ echo "3" >> 2and3.txt
                                                            \n

                                                            Then we can see what each command does using these examples.

                                                            A poker deck is a great starting point for developing game mechanics without getting distracted by what the game assets will look like. Playing cards have lots of unique things you can structure game play around, like two colours, four suits, face cards, Joker, and so on.

                                                            Tarot cards add even more variety, because a tarot deck usually has unique art on every card, which provides you plenty of elements to work with. Etsy has lots of custom tarot decks that are beautifully designed by indie artists.

                                                            An easier option is to use LibreOffice Draw. Go to Page > Page Properties > and set page size to 57mm x 89mm (2.25 x 3.5 inches).

                                                            Minimalism is a great tool for any content creator on a budget. Think of the simplest requirement to convey your game mechanic. If your cards look better than your game mechanics play, nobody's going to play your game. Spend your time and effort on the game, not the design. (There's a balance to be struck, though. If your game assets make no sense and people can't figure out how to play the game, that's a problem too.)

                                                            Our Audio

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We've been making\nsmall adjustments to our audio mix each month in order to get the best\npossible sound. Its been especially challenging getting all of our\nvoices relatively level, because everyone has their own unique setup.\nMumble is great for bringing us all together, and for recording, but\nit's not good at making everyone's voice the same volume. We're pretty\nhappy with the way this month's show turned out, so we'd like to share\nour editing process and settings with you and our future selves (who, of\ncourse, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to\nminimize the silence between people speaking. When used with it's\ndefault (or at least reasonable) settings, Truncate Silence is extremely\neffective and satisfying. It makes everyone sound smarter, it makes the\nfile shorter without destroying actual content, and it makes a\nconversations sound as easy and fluid during playback as it was while it\nwas recorded. It can be even more effective if you can train yourself to\nremain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass\nthe file through Truncate Silence ONCE. If you pass it through a second\ntime, or if you set it too aggressively your audio may sound sped up and\nchoppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                            Threshold: -30db\n\nNoise Floor: -50db\n\nRatio: 3:1\n\nAttack Time: 0.2sec\n\nDecay Time: 1.0 sec`
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on\npeaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter\nfrom the file and save them in a separate file for possible use as\nouttakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around\n-12db while people are speaking, and we try to keep the peaks under\n-6db, and we adjust the Gain on each of the new tracks so that all\nvolumes are similar, and more importantly comfortable. Once this is done\nwe can \"Mix and Render\" all of our tracks into a single track for export\nto the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the\nshownotes. This is when we can cut out anything that needs to be cut,\nand we can also make sure that we put any links in the shownotes that\nwere talked about during the recording of the show. We finish the\nshownotes before exporting the .aup file to .FLAC so that we can paste a\ncopy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the\nintro, outro and possibly outtakes, and we rename each track\naccordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after\neach of these steps. Audacity has a reputation for being \"crashy\" but if\nyou remember save after every major transform, you will wonder how it\never got that reputation.

                                                            Cybercrime, also known as scams or fraud, is constantly evolving due\nto the many data breaches occurring around the world. Attackers gather\nmore of our personal data from these data breaches, then use that data\nto develop or modify their attacks. Users must remain on guard against\nsocial engineered attacks aimed at defrauding users of personal\ninformation and/or property (usually money/currency). I’m suggesting\nusers update themselves as they would update their computers. Knowing\nthe types of attacks and how the attack is deployed will benefit you in\nthe fight against Cybercrime.

                                                            I've been meaning to put down my thoughts about SystemD for the HPR\ncommunity for some while, so here goes.

                                                            \n

                                                            I want to say that I am not a SystemD hater. When SystemD was a hot\ntopic of debate, many became irrational over it, but I want to start by\nsaying that I don't think it's a bad technology. I think it is a rather\ngood technology. I just don't want it on my personal computer. So I\nwould like to run things down in this order: what is it (as in, what is\nit really,) what makes it a good technology, why I don't want it now\n(but might later,) and a few tips for you if you decide that you don't\nwant it currently.

                                                            \n

                                                            SystemD Is not an init system. SystemD includes an init system.\nSystemD Init was faster than SysVInit, but SystemD Init isn't the\nfastest init system, and SysVInit now has a parallelization helper, at\nleast on Debian.

                                                            \n

                                                            So, if SystemD Init is not SystemD, than what is SystemD? To\nunderstand this we must first understand something about Linux. Linux\noperates under a model where there are root processes, and there are\nuser processes. These two kinds of processes are usually called\n\"layers.\" SystemD is actually a third layer, that can be called a system\nlayer. So when SystemD is added to a Linux system, that changes the\nsystem so that there are three layers, a root layer, a user layer, and a\nsystem layer. As such, you now ask SystemD to set how the system runs.\nThis is why SystemD includes things like an init system, because if you\nwant to change what the system is running, you ask SystemD to change it.\nSystemD then messages an appropriate system to implement the change,\nlike messaging its init system to bring up or bring down a system\ndaemon. Once you play out this in your head a bit, you really realize\nthat SystemD acts more like a message passing system in this regard.

                                                            \n

                                                            So why do I say SystemD is a good technology? Because this can\nstandardize system control. Without SystemD a fleet of computers becomes\nlike individual fingerprints or unique snowflakes. If you manage many\ncomputers, as many professional IT people do, you want them to all run\nthe same, all have the same profiles and general configurations. So if\nyou have a bunch of computers you are running, you can run a lot more if\nthey are all run the same way. If your job requires you to run 10,000\nwebservers, you want them to run identically because it is impossible to\nkeep an understanding of 10,000 unique configurations in a human\nhead.

                                                            \n

                                                            SystemD really shines in its support of virtualization as well. So\nto speak of servers, I used to run an email server for a few friends.\nEach of us had a userid and number as unix users. The mapping of unix\nuserids and postfix userids can get confusing when it gets big. Thanks\nto SystemD's virtualization work, you can actually put a service like\nemail into a namespace situation so that it has only the users root and\nthe daemon user id (like \"postfix\"), so SystemD greatly enhances\nsecurity for server installations. This might help explain its\ndominance in linux distributions that have been traditionally\nserver-centric, such as debian and redhat.

                                                            \n

                                                            So why don't I don't want it? Well, I've been doing a lot of talking\nabout professional computer work and corporate work environments, but I\nuse a \"Personal Computer\" as a hobby. I've been out-of-industry for\ndecades now. And when I say \"Personal Computer\" I'm not talking a\nhardware specification, rather I'm talking about \"This is my personal\ncomputer where I do things my way, as opposed to my work computer where\nI do things my companies way\". Dear listener, please remember that I did\nthe first community show contribution to HPR, and my topic was about\npersonalization. For me, a hobbyist interested in operating system\nexperimentation, I don't want a system layer, I want a traditional\nunix-like system that operates on a two-layer model and does things my\nway, nobody else's way.

                                                            \n

                                                            So, what advice can I give to those who don't want SystemD now? Well,\nrecently I've left Debian. Debian, you see, supports init system\ndiversity, but as you now know dear listener, that is different than\nbeing without SystemD. You may have heard that SystemD is\nlinux-specific, that is to say that it runs only on linux, not anything\nlike a BSD system or a Windows system. But you may be curious to know\nthat it is also Gnu-libC specific. Which means that the C compiler must\nuse GNU's libC standard library. Thus, if you have a system built around\nthe Musl C standard library like Alpine or Void, or a system like\nAndroid that runs on the Bionic C Standard library, you wont have a\nSystemD system. I'm personally learning Void as its package manager\nsupports both binary and a ports collection much like the BSD's. But\nthat is what I'm doing on my personal computer, I leave you in the\nfreedom to do things your way on your personal computer!

                                                              repetition of this is what builds friendship. this is why friendships often develop at work, but can dissolve quickly after a job change.

                                                              the situation matters. chatting with someone who's being paid to interact with you, like somebody working at a store, doesn't count because in context they more or less cannot choose to stop communicating with you until you leave the store. chatting with someone who has anything to gain by chatting with you doesn't count (like an intern at work).

                                                              to speed up a developing friendship, you can invite the person to interact with you on something with a clearly defined goal. You like coding? I like coding! Would you care to collaborate for 4 hours on a script that would help me find my Raspberry Pi on my network?

                                                              \n

                                                            • \n

                                                              during the activity, continue to communicate. this can be difficult because you're doing an activity that you both claim to enjoy, so in theory the activity should be sufficient to further the friendship. However, the activity doesn't build the friendship, it only builds a partnership. It's the communication that builds friendship.

                                                              \n

                                                            unfortunately, there's no clear point during this process at which you know you have made a friend. so you have to define what a friend is, to you, and then work toward that goal.

                                                            \n

                                                            Here are some examples of definitions for friendship. There is no right or wrong here, it's really just setting your own expectations and requirements:

                                                            \n
                                                              \n

                                                              • What is a \"Vulnerability\"\n(computing)? Vulnerabilities are flaws in a computer system that\nweaken the overall security of the device/system. Vulnerabilities can be\nweaknesses in either the hardware itself, or the software that runs on\nthe hardware.
                                                                • \n
                                                              • What is an \"Attack\nSurface\"? The attack surface of a software environment is the sum of\nthe different points (for \"attack vectors\") where an unauthorized user\n(the \"attacker\") can try to enter data to or extract data from an\nenvironment. Keeping the attack surface as small as possible is a basic\nsecurity measure.
                                                                • \n
                                                              • What is an \"Attack\nVector\"? In computer security, an attack vector is a specific path,\nmethod, or scenario that can be exploited to break into an IT system,\nthus compromising its security. The term was derived from the\ncorresponding notion of vector in biology. An attack vector may be\nexploited manually, automatically, or through a combination of manual\nand automatic activity.
                                                                • \n
                                                              • What is\n\"Standardization\"? Standardization is the process of implementing\nand developing technical standards based on the consensus of different\nparties that include firms, users, interest groups, standards\norganizations and governments. Standardization can help maximize\ncompatibility, interoperability, safety, repeatability, or quality. It\ncan also facilitate a normalization of formerly custom processes.\n

                                                              • What is a \"Replay\nattack\"? A replay attack is a form of network attack in which valid\ndata transmission is maliciously or fraudulently repeated or delayed.\nAnother way of describing such an attack is: \"an attack on a security\nprotocol using a replay of messages from a different context into the\nintended (or original and expected) context, thereby fooling the honest\nparticipant(s) into thinking they have successfully completed the\nprotocol run.\"
                                                                • \n
                                                              • What is a\n\"Man-in-the-middle attack\"? In cryptography and computer security, a\nman-in-the-middle, ..., attack is a cyberattack where the attacker\nsecretly relays and possibly alters the communications between two\nparties who believe that they are directly communicating with each\nother, as the attacker has inserted themselves between the two\nparties.
                                                                • \n
                                                              • What is \"Transport Layer\nSecurity\" (TLS)? Transport Layer Security (TLS) is a cryptographic\nprotocol designed to provide communications security over a computer\nnetwork. The protocol is widely used in applications such as email,\ninstant messaging, and voice over IP, but its use in securing HTTPS\nremains the most publicly visible.
                                                                • \n

In computing, a handshake is a signal between two\ndevices or programs, used to, e.g., authenticate, coordinate. An example\nis the handshaking between a hypervisor and an application in a guest\nvirtual machine.
                                                                • \n

                                                            \n

                                                            I have occasionally been using a tool called ack for a\nfew years now. It’s billed as “an alternative to grep for\nprogrammers”.

                                                            \n

                                                            There are several features I find particularly useful:

                                                            \n
                                                              \n

                                                            • It can restrict text searches to files of a particular\ntype

                                                              • \n

                                                            • It uses Perl regular expressions which may be the most powerful\nand feature rich types of RE’s available at present

                                                              • \n

                                                            • You can limit the search area within a file if desired

                                                              • \n
                                                            \n

                                                            It is a very comprehensive and useful tool, though maybe quite\ncomplex to use. Personally I use it in special cases where I need its\npower, and otherwise use the usual grep.

                                                            \n

                                                            In this episode I will give you the flavour of its capabilities and\notherwise leave you to research more if it sounds interesting.

                                                            \n

                                                            Installing ack

                                                            \n

                                                            The tool can be found in repositories. I use Debian, and\nack is in the Debian repo and can be installed with:

                                                            \n
                                                            sudo apt install ack
                                                            \n

                                                            Installing it this way the version I have (and am describing here) is\n3.6.0. There is a new version, 3.7.0 available from the website.

                                                            \n

                                                            The documentation on the website suggests installing it as a Perl\nmodule using CPAN, which is something I will do soon I\nthink.

                                                            \n

                                                            Perl regular expressions

                                                            \n

                                                            These are very sophisticated.

                                                            \n

                                                            A project to convert the Perl regular expression capabilities into a\nportable library form was undertaken by Philip Hazel of Cambridge\nUniversity in 1997, and was called Perl Compatible Regular\nExpressions or PCRE.

                                                            \n

                                                            Philip Hazel was the originator of the exim mail\ntransfer agent (MTA, or mail server), and wanted to use PCRE within\nit.

                                                            Since then PCRE (and later PCRE2) is the way regular expressions are\nimplemented in a lot of other software, which shows how widespread use\nof the Perl RE has become.

                                                            \n

                                                            The ack documentation refers to the Perl manual for\ndetails of this type of regular expression, and to a tutorial, if you\nwish to gain a deeper understanding.

                                                            \n

                                                            It should be noted that GNU grep can use Perl compatible\nregular expressions when matching lines in files, but this feature is\nmarked as experimental.

                                                            \n

                                                            File types

                                                            \n

                                                            The ack command has rules for recognising file types. It\ndoes this by looking at the name extensions ('.html' or\n'.py' for example), and in some cases by examining their\ncontents. The complete list of types can be found by running:

                                                            \n
                                                            ack --help-types
                                                            \n

                                                            … or, for a more detailed but less readable list:

                                                            \n
                                                            ack --dump
                                                            \n

                                                            Some examples are:

                                                              • \n

                                                              • \n
                                                            • lua for Lua files
                                                              • \n
                                                            • python for Python files
                                                              • \n

                                                              • \n
                                                            \n

                                                            These names can be used with the options -t TYPE and\n--type=TYPE and also by simply preceding them with two\ndashes (--TYPE). There are also ways of requesting files\nnot of a given type: -T TYPE, --type=noTYPE\nand --noTYPE.

                                                            \n

                                                            To check files in the current directory of type shell an\nack command like the following might be used and the\nfollowing type of output produced:

                                                            \n
                                                            $ ack --shell declare\nBash_snippet__using_coproc_with_SQLite/examples/coproc_test.sh\n11:declare -a com=('date +%F' 'whoami' 'id' 'echo "$BASH_VERSION"'
                                                            \n

                                                            Note that ack reports the file path and numbered lines\nwithin it that match.

                                                            \n

                                                            You can add your own file types to ack. There is a\nconfiguration file called .ackrc in which new types can be\ndeclared. See below for more information.

                                                            \n

                                                            The file type feature is one that makes me use ack again\nand again.

                                                            \n

                                                            The .ackrc file

                                                            \n

                                                            This file contains “command-line options that are prepended to\nthe command line before processing”.

                                                            \n

                                                            It’s a useful way to add new types (or even modify existing\nones).

                                                            \n

                                                            It can be located in a number of places. Mine is\n~/.ackrc with other configuration files in my home\ndirectory.

                                                            \n

                                                            It’s possible to generate a new .ackrc with the option\n--create-ackrc. This saves all the default settings in the\nfile which makes it simple to adjust anything you need to change.

                                                            \n

                                                            As an example of a change, I have Markdown files with the extension\n.mkd. However, by default ack only recognises\n.md, and .markdown. To add .mkd\nto the list I can add one of the following to the\n.ackrc:

                                                            \n
                                                            # Either add `.mkd` to the list\n--type-add=markdown:ext:mkd\n# or replace the list with a new one\n--type-set=markdown:ext:md,mkd,markdown
                                                            \n

                                                            Note that lines beginning with # are comments. Note also\nthat --type-add and --type-set have to be\nfollowed by an = sign, not a space in this file.

                                                            \n

                                                            If you examine the settings with ack --dump you will see\nthe default command and the one you have added. If you use\nack --help-types you will see the new extension added to\nthe default list.

                                                            \n
                                                            markdown     .md .markdown; .mkd
                                                            \n

                                                            If I use this to search files in the directory where I keep my HPR\nepisodes I see:

                                                            \n
                                                            $ ack --markdown 'inner ear'\nHacking_my_inner_ear/hpr2109_full_shownotes.mkd\n24:became fascinated by the structure of the human [inner ear][2], and studied it\n28:The human inner ear performs two major functions:\n.\n.\n.

                                                            Quick review of selected\nack options

                                                            \n

                                                            Usage

                                                            \n

                                                            The ack command is designed to be similar in as many\nrespects as possible to grep. The command is used in\ngeneral as follows:

                                                            \n
                                                            ack [OPTION]... PATTERN [FILES OR DIRECTORIES]
                                                            \n

                                                            The [OPTION] part denotes any options (some discussed\nbelow) and PATTERN is the PCRE search pattern. There are\nsome cases where this must be omitted - such as when files of a\nparticular type are being listed. See example 1 below for such a\ncase.

                                                            \n

                                                            In some cases a particular file is being searched, or all files in\ncertain directories, and that is what\n[FILES OR DIRECTORIES] denotes.

                                                            \n

                                                            The full documentation for ack can be seen with the\nusual man ack command, and also using\nack --man. There is also an option --help\nwhich gives a summary of all of the available options.

                                                            \n

                                                            Options

                                                            \n

                                                            There are many options specific to ack and some in\ncommon with grep, and we’ll look at just a few here:

                                                            \n
                                                              \n

                                                            • -i - like grep this makes the matched\npattern case insensitive.

                                                              • \n

                                                            • -f - Only print the files that would be searched,\nwithout actually doing any searching. See example 1 below.

                                                              • \n

                                                            • -g - Same as -f, but only select files whose names\nmatch PATTERN. This interacts with file type searches like\n--html, so beware.

                                                              • \n

                                                            • -l - reports the file names which contain matches\nfor a given pattern

                                                              • \n

                                                            • -L - reports the file names which do not\ncontain matches for a given pattern

                                                              • \n

                                                            • -c - reports file names and the number of matches;\nused on its own it reports all files, those that match and\nthose that do not. If used with -l then you only see the\nnames of file that have matches, as well as a count of matches. See\nexample 2 below.

                                                              • \n

                                                            • -w - forces the search pattern to match only whole\nwords. See example 3 below. (Note: there is an equivalent in GNU grep,\nwhich I had not checked when I recorded the audio).

                                                              • \n
                                                            \n

                                                            Examples

                                                            Biltong is a form of dried, cured meat which originated in Southern African countries (South Africa, Zimbabwe, Malawi, Namibia, Botswana, Eswatini and Zambia). Various types of meat are used to produce it, ranging from beef to game meats such as ostrich or kudu. The cut may also vary being either fillets of meat cut into strips following the grain of the muscle, or flat pieces sliced across the grain. It is related to beef jerky; both are spiced, dried meats; however the typical ingredients, taste, and production processes may differ.

                                                            The word \"biltong\" is from the Dutch bil (\"buttock\") and tong (\"strip\" or \"tongue\").

                                                            Since then, there has been a process of adapting the software to the\nnew configuration. Unfortunately Rho`n has not been\navailable during this process, but we are gradually learning our way\naround his excellent software and making changes to suit our needs.

This not\nonly let us visit a much different part of the country, but it also\nallowed us to go back to our plan to visit some NASA facilities.

                                                            P.S. Some people really like finding mistakes. For their enjoyment,\nwe always include a few.

                                                            \n
                                                            \n

                                                            This episode was processed using Audacity. We've been making\nsmall adjustments to our audio mix each month in order to get the best\npossible sound. Its been especially challenging getting all of our\nvoices relatively level, because everyone has their own unique setup.\nMumble is great for bringing us all together, and for recording, but\nit's not good at making everyone's voice the same volume. We're pretty\nhappy with the way this month's show turned out, so we'd like to share\nour editing process and settings with you and our future selves (who, of\ncourse, will have forgotten all this by then).

                                                            \n

                                                            We use the \"Truncate Silence\" effect with it's default settings to\nminimize the silence between people speaking. When used with it's\ndefault (or at least reasonable) settings, Truncate Silence is extremely\neffective and satisfying. It makes everyone sound smarter, it makes the\nfile shorter without destroying actual content, and it makes a\nconversations sound as easy and fluid during playback as it was while it\nwas recorded. It can be even more effective if you can train yourself to\nremain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass\nthe file through Truncate Silence ONCE. If you pass it through a second\ntime, or if you set it too aggressively your audio may sound sped up and\nchoppy.

                                                            \n

                                                            Next we use the \"Compressor\" effect with the following settings:

                                                            \n
                                                            Threshold: -30db\n\nNoise Floor: -50db\n\nRatio: 3:1\n\nAttack Time: 0.2sec\n\nDecay Time: 1.0 sec
                                                            \n

                                                            \"Make-up Gain for 0db after compressing\" and \"compress based on\npeaks\" were both left un-checked.

                                                            \n

                                                            After compressing the audio we cut any pre-show and post-show chatter\nfrom the file and save them in a separate file for possible use as\nouttakes after the closing music.

                                                            \n

                                                            We adjust the Gain so that the VU meter in Audacity hovers around\n-12db while people are speaking, and we try to keep the peaks under\n-6db, and we adjust the Gain on each of the new tracks so that all\nvolumes are similar, and more importantly comfortable. Once this is done\nwe can \"Mix and Render\" all of our tracks into a single track for export\nto the .FLAC file which is uploaded to the HPR server.

                                                            \n

                                                            At this point we listen back to the whole file and we work on the\nshownotes. This is when we can cut out anything that needs to be cut,\nand we can also make sure that we put any links in the shownotes that\nwere talked about during the recording of the show. We finish the\nshownotes before exporting the .aup file to .FLAC so that we can paste a\ncopy of the shownotes into the audio file's metadata.

                                                            \n

                                                            At this point we add new, empty audio tracks into which we paste the\nintro, outro and possibly outtakes, and we rename each track\naccordingly.

                                                            \n

                                                            Remember to save often when using Audacity. We like to save after\neach of these steps. Audacity has a reputation for being \"crashy\" but if\nyou remember save after every major transform, you will wonder how it\never got that reputation.

                                                            Hello this is Trey, and I am recording this in the shadow of the loss\nof a good friend and mentor who helped guide me in my career and in\nhobbies like electronics, aviation, and amateur radio. The amateur radio\narea is what I will be discussing today.

                                                            \n

                                                            Many terms within amateur radio find their origins from the days of\ntelegraph, when operators would use Morse code to send messages across\ngreat distances using wires strung from pole to pole. The telegraph\n“key” (or code key) was basically a momentary contact switch which would\nclose an electrical connection when pressed. Pressing the key down for a\nshort period of time would send a short pulse down the line, which is\nreferred to as a “dit” (Sometimes the term “dot” is used). This may be\nwritten using the period “.” symbol. Holding the key down for a bit\nlonger would send a longer pulse down the line, called a “dash”\n(Sometimes the term “dah” is used) and it may be written using the\nhyphen “-” symbol.

                                                            Telegraph operators became a close knit community, even though they\nwere geographically separated. Often one operator could identify another\noperator by subtleties in the style or personality of how they sent\ntheir messages. This was known as the operator’s “fist” and today we\nwould describe it as a “behavioral biometric”. As the community of\ntelegraph operators moved around or were replaced, new “fists” would be\nidentified, as new personalities of code sending were tapped out on the\ntelegraph keys.

                                                            \n

                                                            When an operator passed away, it was a loss to the community, and a\nloss of someone who might have been befriended remotely by other\noperators. The term of respect created for this situation was “Silent\nKey” sent as the abbreviation “SK” ( … -.- ). It meant that the\nparticular operator would never send code again. His telegraph key would\nbe silent.

                                                            This tradition has been carried on among amateur radio operators or\n“Hams”. This is also a close knit community of people. While some still\nuse Morse code to communicate (Referred to as “CW” for continuous wave),\nthere are many other forms in use, including voice and digital modes.\nBut regardless of how we communicated with them, when we lose one of our\nown, we still say they are SK. Silent key. No longer able to\ntransmit.

This is caused by the\nrelease of a volatile liquid, syn-propanethial-S-oxide and its aerosol,\nwhich stimulates nerves in the eye. This gas is produced by a chain of\nreactions which serve as a defence mechanism: chopping an onion causes\ndamage to cells which releases enzymes called alliinases. These break\ndown amino acid sulfoxides and generate sulfenic acids. A specific\nsulfenic acid, 1-propenesulfenic acid, is rapidly acted on by a second\nenzyme, the lacrimatory factor synthase (LFS), producing the\nsyn-propanethial-S-oxide. This gas diffuses through the air and soon\nreaches the eyes, where it activates sensory neurons. Lacrimal glands\nproduce tears to dilute and flush out the irritant.
                                                                \n

                                                              • Cooking onions and sweet onions are better stored at room\ntemperature, optimally in a single layer, in large mesh bags in a dry,\ncool, dark, well-ventilated location. In this environment, cooking\nonions have a shelf life of three to four weeks and sweet onions one to\ntwo weeks. Cooking onions will absorb odours from apples and pears.\nAlso, they draw moisture from vegetables with which they are stored\nwhich may cause them to decay.
                                                                \n

                                                              • Sweet onions have a greater water and sugar content than cooking\nonions. This makes them sweeter and milder tasting, but reduces their\nshelf life. Sweet onions can be stored refrigerated; they have a shelf\nlife of around 1 month. Irrespective of type, any cut pieces of onion\nare best tightly wrapped, stored away from other produce, and used\nwithin two to three days.

                                                            For reasons I go into, this is in some respects a different game from\nCivilization II, at least different enough to deserve some separate\nattention. The multiple map feature makes for some interesting game play\npossibilities that add interest to this version, and the fact that it\nhas no defined end point is also intriguing. And the scenarios add some\ninteresting story differences as well.

                                                            Crusader Kings II is a dynasty simulator, where your goal is to guide\nyour dynasty through the middle ages. It's very large game and this\nepisode can only scratch the surface.

You need to manage vassals in your realm and keep your\nneighbours at bay. When you're not busy with that, you can relax and go\nhunting, build an observatory or join a secret society (to name just a\nfew).

                                                            Hi all! Today I'm gonna be talking about my adventures in setting up\nPi-hole. This will be without screenshots, but instead in all text,\nsorry! Also this is all written as kind of an \"Aftermath\" story. This is\nbeing written after the fact, so this might be missing some details, but\nmost of it is there.

                                                            \n

                                                            Intro: What is Pi-hole

                                                            \n

                                                            Pi-hole is a DNS/DHCP server that\nallows for easy network-wide ad-blocking, along with all the nice\ncustomizations that come with being a DNS server, such as custom\ndomains.

                                                            \n

                                                            First Step: Get it running

                                                            \n

                                                            The first step was getting Pi-hole running. I did this using Docker\nCompose on a \"NAS\" which is honestly a full on server at this point. A\nquick copy/paste from Pi-hole's\nREADME and I was up and running! I set a singular system to use this\nas a DNS server, and after that, I figured I was set and ready to\ngo.

                                                            \n

                                                            Second Step: DHCP town

                                                            \n

                                                            Of course, I wasn't satisfied just finishing there. I want automatic\nDNS setting for any device that connects to my network. Of course, I\ncould just set the DNS upstream in my OpenWRT router to use the IP address of\nmy server, but that isn't good enough for me. This means I'd be missing\nout on automatic per-client information, since when setting a DNS server\nfor OpenWRT, it only sets itself to forward any DNS requests up to the\nDNS server, which means from Pi-hole's perspective, all the requests are\ncoming from the router and nowhere else. The solution is to set up\nPi-Hole as a DHCP server. Keep in mind this isn't a tutorial, so let's\ngo through what I did first. The first step was to turn on the DHCP\nserver in Pi-Hole. This was super easy, just a checkbox and click save.\nCool! Then I disabled the DHCP server in OpenWRT, and that was all set.\nA few restarting of network devices later, like my phone, and they\nautomatically connected to the Pi-Hole server, and worked like a charm.\nNext up, I set up Tailscale. I use Headscale, but the setup is\nessentially the same as if you were using Tailscale's UI. Set in the\nconfig to override local DNS, set the nameserver to the Tailscale IP\naddress of the server, and turn on magic DNS, et voila! Now to restart\nthe Tailscale nodes, and make sure that on the server, you set it to not\naccept the DNS from Tailscale. If you don't do that, it'll get in an\nendless loop of trying to use itself as the DNS server, and it's just no\ngood. Okay! It's all set, and I check the dashboard, and it's already\nblocking DNS requests. Perfect!

                                                            \n

                                                            Third Step: Whoopsies!

                                                            \n

                                                            This was fine and great, but when I went to reboot my server, which I\ndo weekly, something bad happened. The interface for the server didn't\ncome up. This is a problem, since it's the DHCP server for my network,\nso without that working, the network was dead in the water. It can't\ngive out IP addresses. What's going on? I go ahead and access my server\ndirectly. No matter how hard I try, it can't connect to the interface.\nWhat's the big deal? Well this is pretty simple, and a question popped\nin my head that go me there. \"How does this server even get its IP\naddress?\" You see when I set up pi-hole, it just kept using the IP\naddress that the router gave it, which it was more than happy to use,\nbut the moment the router didn't have a DHCP server, the NAS didn't have\na way to get an IP address anymore. So what do you do then? The answer\nis pretty simple. Give the server a static IP. Make sure in the DHCP\nserver of pi-hole, you set a reservation in it for the server, then in\nNetworkManager, which I use, set it to have a static IP, and set its DNS\nto point to localhost. Perfect! This works like a charm!

                                                            \n

                                                            Fourth Step: Adlists

                                                            \n

                                                            Okay, phew! Crisis averted. Just some missing networking knowledge.\nSo what's next up on the list? Hmmm... Let's see... The default adlist\nis kinda small, let's go see if we can find some new adlists. Apparently\nthis is more difficult than you'd think. A quick search on DDG only came\nup with an equivalent search in GitHub. Not useful! I have no idea the\ntrustworthiness and stability of these adlists. Let's see. Another\nsearch leads to a Reddit article that then links to a different list.\nBingo! An Adlist list. Exactly what I\nneeded. I went ahead and looked into these lists, and added a few of\nthem. Perfect!

                                                            \n

                                                            Fifth Step: Maintenance

                                                            \n

                                                            docker compose pull && docker compose up -d
                                                            \nOf course, this isn't it. I actually use an a/b update scheme, but you\nget the gist. Updates are taken care of, and just make sure you try and\nkeep the server up as long as possible, and keep downtime to a\nminimum.

                                                            \n

                                                            Sixth Step: Moving off the\nNAS.

                                                            \n

                                                            After a while of running this, the necessity of having the NAS on the\nwhole time was starting to get frustrating. The answer there was to move\nit off the NAS. I did this by installing it on a Raspberry Pi 3B,\nrunning Arch Linux ARM. The setup was identical to before once I had\ngotten ALARM running.

Coherent Unix had to make a choice to compete with either Windows,\nSCO Unix, or Linux, and had enough budget to add either X Windows or\nTCP/IP networking. They chose X11, and IMO that killed any chance of\nCoherent Unix being useful in a world of Linux and FreeBSD.

RVs are said to\nundergo an earthquake every time you tow them, and so there are things\nthat need to be addressed. And the tow vehicle needs to be in good shape\nas well. So in this episode we discuss how we did the necessary\nequipment maintenance.

We're adding plugins\nto support open source large language models (LLMs) like GPT-2 and\nLlama2. Here's how you can use LLMs in your own Python Programs.

                                                            \n

                                                            1. Create a Hugging Face account:

                                                            1. Create and copy your access token:
                                                              2. \n

                                                            1. Create a .env file with your access token string:

                                                            echo "HUGGINGFACE_ACCESS_TOKEN=hf_..." >> .env

                                                              \n
                                                            1. Load the .env variables in your python script using\ndotenv package and os.environ:
                                                              2. \n

                                                              \n
                                                            • TIP: Use os.environ to retrieve the dict of variable\nvalues rather than dotenv.load_values- Otherwise other\nenvironment variables that have been set by other shell scripts such as\n.bashrc will be ignored.

                                                            Some of you may know me from in COM chat on sdf dot org or as a\nfedizen on the tilde dot zone instance of mastodon.

                                                            \n

                                                            Now, the other day I finally got around to checking out HPR properly,\neven though my masto-pal claw-dio-m turned me on to it a couple of years\nago.

                                                            \n

                                                            Recently, on a friday night in irc on tilde radio, I noticed there\nwere whole series on hpr and not only single shows and that got me kind\nof excited.
                                                            \nI guess I'm easily excitable.

                                                            \n

                                                            Anyhow, something I could listen to at work or while driving. Still,\nI managed to forget about it until /just/ before I was leaving the house\nfor work on Monday morning. I rushed to copy over a few shows - nearly\nat random onto my phone and headed out to work.

                                                            \n

                                                            After I got my morning sorted at work, I told VLC to play-all and\nenjoyed a couple of shows. I noticed that each show I had chosen had a\nbeg post at the beginning. I figured I could make one on at least\nsomething from my messy gemlog/bin dir.

                                                            \n

                                                            However, after a break, I came back and couldn't remember which 4\ndigit numbered dot mp3 I had finished up on, which mildly irked me.\nWell, as we all know, irk becomes itch and I put my sad regex skills to\nthe test scraping the hpr website with a custom bash script later when I\ngot home.

                                                            \n

                                                            A very custom bash script. Like all scrapers, if any of the guys at\nhpr even breathe the wrong way, it will probably break horribly. On the\nother hand, I've had scrapers that looked just as sad running for many\nyears against a canadian government site. So. Who knows?

                                                            \n

                                                            All the script uses are some built-ins from bash along with sed and\nwget for the actual getting. My local instance of searX N G was left\nsmoking as scrambled for sed incantations to string together. I'm not a\nsed guy.

                                                            \n

                                                            Usage is simple, as the script only accepts one argument: ... the\nfour digit series number of the show you want to download. It will\ncreate a dir with the series name and download every mp3 it finds,\nrenaming each show to the show title.

                                                            \n

                                                            I was tempted to doll it up with some niceties like options for\ndownload dir, a selector for a series with a dialog of some kind... yada\nyada yada.

                                                            \n

                                                            But... we all know what happens when you stretch a quick hack with a\nbash script too far for the scripting language: hours of misery wishing\nyou'd started with some other language.

                                                            \n

                                                            So far, I've used the script to download 8 series. DU dash S H tells\nme they add up to 2 dot 2 gig, so it seems to work well enough.

                                                            \n

                                                            It comes with the same iron clad warranty as everything I write:

                                                            \n

                                                            Some thoughts on the different ways you can run an open source\nsoftware project, comparing projects like password-store, which are\nbased on a mailing list and use a minimal forge platform, and others\nthat are based on a fancy forge like Github.

                                                            \n

                                                            I think the fancy forge gives the open source software project a vibe\nthat we're more used to, in our capitalist society. It's a more\ncentralized structure that feels more like a service that's being\noffered to the public, mostly in one direction. Meanwhile software\nprojects that don't have a platform for creating road maps, issues, pull\nrequests etc actually foster a stronger and more open community\nstructure, rather counter-intuitively, because the software is free and\neveryone is able to contribute and modify the software for their own\nuse, and they in fact do. The idea of a canonical version of the\nsoftware is only a convenience, not a defining feature of it.

                                                            Here I describe my method for creating a macro using equalizer,\ncompressor and normalize presets in Audacity, which can be used\nrepeatedly to get consistent results, as long as you use the same voice,\nmicrophone and recording location.

                                                            Overview

                                                            \n

                                                            Recently Ken Fallon did a show on HPR, number\n3962, in which he used a Bash\npipeline of multiple commands feeding their output into a\nwhile loop. In the loop he processed the lines produced by\nthe pipeline and used what he found to download audio files belonging to\na series with wget.

                                                            \n

                                                            This was a great show and contained some excellent advice, but the\nuse of the format:

                                                            \n
                                                            pipeline | while read variable; do ...
                                                            \n

                                                            reminded me of the \"gotcha\" I mentioned in my own show\n2699.

                                                            \n

                                                            I thought it might be a good time to revisit this subject.

                                                            \n

                                                            So, what's the problem?

                                                            \n

                                                            The problem can be summarised as a side effect of pipelines.

                                                            \n

                                                            What are pipelines?

                                                            \n

                                                            Pipelines are an amazingly useful feature of Bash (and other shells).\nThe general format is:

                                                            \n
                                                            command1 | command2 ...
                                                            \n

                                                            Here command1 runs in a subshell and produces output (on\nits standard output) which is connected via the pipe symbol\n(|) to command2 where it becomes its\nstandard input. Many commands can be linked together in this\nway to achieve some powerful combined effects.

                                                            \n

                                                            A very simple example of a pipeline might be:

                                                            \n
                                                            $ printf 'World\nHello\n' | sort\nHello\nWorld
                                                            \n

                                                            The printf command (≡'command1') writes two\nlines (separated by newlines) on standard output and this is\npassed to the sort command's standard input\n(≡'command2') which then sorts these lines\nalphabetically.

                                                            \n

                                                            Commands in the pipeline can be more complex than this, and in the\ncase we are discussing we can include a loop command such as\nwhile.

                                                            \n

                                                            For example:

                                                            \n
                                                            $ printf 'World\nHello\n' | sort | while read line; do echo "($line)"; done\n(Hello)\n(World)
                                                            \n

                                                            Here, each line output by the sort command is read into\nthe variable line in the while loop and is\nwritten out enclosed in parentheses.

                                                            \n

                                                            Note that the loop is written on one line. The semi-colons are used\ninstead of the equivalent newlines.

                                                            \n

                                                            Variables and subshells

                                                            \n

                                                            What if the lines output by the loop need to be numbered?

                                                            \n
                                                            $ i=0; printf 'World\nHello\n' | sort | while read line; do ((i++)); echo "$i) $line"; done\n1) Hello\n2) World
                                                            \n

                                                            Here the variable 'i' is set to zero before the\npipeline. It could have been done on the line before of course. In the\nwhile loop the variable is incremented on each iteration\nand included in the output.

                                                            \n

                                                            You might expect 'i' to be 2 once the loop exits but it\nis not. It will be zero in fact.

                                                            \n

                                                            The reason is that there are two 'i' variables. One is\ncreated when it's set to zero at the start before the pipeline. The\nother one is created in the loop as a \"clone\". The expression:

                                                            \n
                                                            ((i++))
                                                            \n

                                                            both creates the variable (where it is a copy of the one in the\nparent shell) and increments it.

                                                            \n

                                                            When the subshell in which the loop runs completes, it will delete\nthis version of 'i' and the original one will simply\ncontain the zero that it was originally set to.

                                                            \n

                                                            You can see what happens in this slightly different example:

                                                            \n
                                                            $ i=1; printf 'World\nHello\n' | sort | while read line; do ((i++)); echo "$i) $line"; done\n2) Hello\n3) World\n$ echo $i\n1
                                                            \n

                                                            These examples are fine, assuming the contents of variable\n'i' incremented in the loop are not needed outside it.

                                                            \n

                                                            The thing to remember is that the same variable name used in a\nsubshell is a different variable; it is initialised with the value of\nthe \"parent\" variable but any changes are not passed back.

                                                            \n

                                                            How to avoid the\nloss of changes in the loop

                                                            \n

                                                            To solve this the loop needs to be run in the original shell, not a\nsubshell. The pipeline which is being read needs to be attached to the\nloop in a different way:

                                                            \n
                                                            $ i=0; while read line; do ((i++)); echo "$i) $line"; done < <(printf 'World\nHello\n' | sort)\n1) Hello\n2) World\n$ echo $i\n2
                                                            \n

                                                            What is being used here is process\nsubstitution. A list of commands or pipelines are enclosed with\nparentheses and a 'less than' sign prepended to the list\n(with no intervening spaces). This is functionally equivalent to a\n(temporary) file of data.

                                                            \n

                                                            The redirection feature allows for data being read from a\nfile in a loop. The general format of the command is:

                                                            \n
                                                            while read variable\n    do\n       # Use the variable\n    done < file
                                                            \n

                                                            Using process substitution instead of a file will achieve what is\nrequired if computations are being done in the loop and the results are\nwanted after it has finished.

                                                            \n

                                                            Beware of this type of\nconstruct

                                                            \n

                                                            The following one-line command sequence looks similar to the version\nusing process substitution, but is just another form of pipeline:

                                                            \n
                                                            $ i=0; while read line; do echo $line; ((i++)); done < /etc/passwd | head -n 5; echo $i\nroot:x:0:0:root:/root:/bin/bash\ndaemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin\nbin:x:2:2:bin:/bin:/usr/sbin/nologin\nsys:x:3:3:sys:/dev:/usr/sbin/nologin\nsync:x:4:65534:sync:/bin:/bin/sync\n0
                                                            \n

                                                            This will display the first 5 lines of the file but does it by\nreading and writing the entire file and only showing the first 5 lines\nof what is written by the loop.

                                                            \n

                                                            What is more, because the while is in a subshell in a\npipeline changes to variable 'i' will be lost.

                                                            \n

                                                            I have always wondered about processes in Unix. The process you log\nin to, normally called a shell runs a command language\ninterpreter that executes commands read from the standard input or\nfrom a file. There are several such interpreters available, but we're\ndealing with bash here.

                                                            \n

                                                            Processes are fairly lightweight entities in Unix/Linux. They can be\ncreated and destroyed quickly, with minimal overhead. I used to work\nwith Digital Equipment Corporation's OpenVMS operating system\nwhich also uses processes - but these are much more expensive to create\nand destroy, and therefore slow and less readily used!

                                                            \n

                                                            Bash pipelines, as discussed, use subshells. The description\nin the Bash man page says:

                                                            \n
                                                            \n

                                                            Each command in a multi-command pipeline, where pipes are created, is\nexecuted in a subshell, which is a separate process.

                                                            \n
                                                            \n

                                                            So a subshell in this context is basically another child\nprocess of the main login process (or other parent process), running\nBash.

                                                            \n

                                                            Processes (subshells) can be created in other ways. One is to place a\ncollection of commands in parentheses. These can be simple Bash\ncommands, separated by semi-colons, or pipelines. For example:

                                                            \n
                                                            $ (echo "World"; echo "Hello") | sort\nHello\nWorld
                                                            \n

                                                            Here the strings \"World\" and \"Hello\", each\nfollowed by a newline are created in a subshell and written to standard\noutput. These strings are piped to sort and the end result\nis as shown.

                                                            \n

                                                            Note that this is different from this example:

                                                            \n
                                                            $ echo "World"; echo "Hello" | sort\nWorld\nHello
                                                            \n

                                                            In this case \"World\" is written in a separate command,\nthen \"Hello\" is written to a pipeline. All\nsort sees is the output from the second echo,\nwhich explains the output.

                                                            \n

                                                            Each process has a unique numeric id value (the process id\nor PID). These can be seen with tools like ps or\nhtop. Each process holds its own PID in a Bash variable\ncalled BASHPID.

                                                            \n

                                                            Knowing all of this I decided to modify Ken's script from show\n3962 to show the processes being created - mainly for my interest,\nto get a better understanding of how Bash works. I am including it here\nin case it may be of interest to others.

                                                            \n
                                                            #!/bin/bash\n\nseries_url="https://hackerpublicradio.org/hpr_mp3_rss.php?series=42&full=1&gomax=1"\ndownload_dir="./"\n\npidfile="/tmp/hpr3962.sh.out"\ncount=0\n\necho "Starting PID is $BASHPID" > $pidfile\n\n(echo "[1] $BASHPID" >> "$pidfile"; wget -q "${series_url}" -O -) |\\n    (echo "[2] $BASHPID" >> "$pidfile"; xmlstarlet sel -T -t -m 'rss/channel/item' -v 'concat(enclosure/@url, "→", title)' -n -) |\\n    (echo "[3] $BASHPID" >> "$pidfile"; sort) |\\n    while read -r episode; do\n\n        [ $count -le 1 ] && echo "[4] $BASHPID" >> "$pidfile"\n        ((count++))\n\n        url="$( echo "${episode}" | awk -F '→' '{print $1}' )"\n        ext="$( basename "${url}" )"\n        title="$( echo "${episode}" | awk -F '→' '{print $2}' | sed -e 's/[^A-Za-z0-9]/_/g' )"\n        #wget "${url}" -O "${download_dir}/${title}.${ext}"\n    done\n\necho "Final value of \$count = $count"\necho "Run 'cat $pidfile' to see the PID numbers"
                                                            \n

                                                            The point of doing this is to get information about the pipeline\nwhich feeds data into the while loop. I kept the rest\nintact but commented out the wget command.

                                                            \n

                                                            For each component of the pipeline I added an echo\ncommand and enclosed it and the original command in parentheses, thus\nmaking a multi-command process. The echo commands write a\nfixed number so you can tell which one is being executed, and it also\nwrites the contents of BASHPID.

                                                            \n

                                                            The whole thing writes to a temporary file\n/tmp/hpr3962.sh.out which can be examined once the script\nhas finished.

                                                            \n

                                                            When the script is run it writes the following:

                                                            \n
                                                            $ ./hpr3962.sh\nFinal value of $count = 0\nRun 'cat /tmp/hpr3962.sh.out' to see the PID numbers
                                                            \n

                                                            The file mentioned contains:

                                                            \n
                                                            Starting PID is 80255\n[1] 80256\n[2] 80257\n[3] 80258\n[4] 80259\n[4] 80259
                                                            \n

                                                            Note that the PID values are incremental. There is no guarantee that\nthis will be so. It will depend on whatever else the machine is\ndoing.

                                                            \n

                                                            Message number 4 is the same for every loop iteration, so I stopped\nit being written after two instances.

                                                            \n

                                                            The initial PID is the process running the script, not the login\n(parent) PID. You can see that each command in the pipeline runs in a\nseparate process (subshell), including the loop.

                                                            \n

                                                            Given that a standard pipeline generates a process per command, I was\nslightly surprised that the PID numbers were consecutive. It seems that\nBash optimises things so that only one process is run for each element\nof the pipe. I expect that it would be possible for more processes to be\ncreated by having pipelines within these parenthesised lists, but I\nhaven't tried it!

                                                            \n

                                                            I found this test script quite revealing. I hope you find it useful\ntoo.

Mounting may happen automatically if the medium contains a readable\nfile system. In the best case, it will prevent the burn programs from\nusing the burner device.

                                                            \nThis time of year can be stressful.

                                                            \n

                                                            A few years ago, I discovered a fun activity, which challenged my\nmind and helped me focus and detach from the stress for a little while\neach day, through the month of December. It helped me manage the stress\nin an enjoyable way.

                                                            \n

                                                            Since then, I have found and tried several other similar activities,\nso I wanted to share a little about them with you for the next few\nepisodes so you can see what might work for you.

                                                            \n

                                                            The first I would like to share is called the Advent of Code\nChallenge (https://adventofcode.com/). In HPR episodes 2973 (https://hackerpublicradio.org/eps/hpr2973/index.html)\nand 3744 (https://hackerpublicradio.org/eps/hpr3744/index.html),\nDaniel Perrson shared some great details about this challenge. I\nencourage you to go review his episodes.

                                                            \n

                                                            But the TLDR (Or maybe the TLDL -- Too Long Didn't Listen?) for\nAdvent of Code is that it is a 25 day challenge which begins on December\n1. Once you register at adventofcode.com, Each day, you will be\npresented with a problem to solve and some sample data to use for\nverification that your program works. You can choose to use any\nprogramming language or application you desire produce the answer. Last\nyear, I used this to brush up on my Python skills. Others use Visual\nBasic, C (and all its variants), Rust, Go, etc. I have seen people use\nCobol, Fortran, and Pascal, or even Microsoft Excel. It is really up to\nyou. You are then presented a dataset which is unique to your login, and\nagainst which you run your code. When complete, you submit the answer\ncame up with on the adventofcode.com web site and they will tell you if\nyou are correct or not.

                                                            \n

                                                            If you are competitive (And REALLY GOOD) there is a Global\nLeaderboard. If you want to compete with a group of friends, you can\nbuild your own leaderboard and invite others to take part with you.

                                                            \n

                                                            There are tons of resources online, from youtube channels to reddit\n(https://www.reddit.com/r/adventofcode/), to Discord (https://discord.gg/tXJh262)

                                                            \n

                                                            So, if you are looking for a way to challenge your mind and detach\nfrom holiday stress, Advent of Code may be something you might try.

                                                            \n

                                                            If this is not your cup of tea, I will be sharing several other\noptions for holiday challenges in future episodes.

                                                            A few months ago I wondered how to deal with them reliably (and\neasily). There are many sites offering to transcribe English (and other\nlanguages) to IPA, a few of which are free. I only found one that would\nattempt to speak IPA, and that is IPA\nReader.

                                                            \n

                                                            Paste the IPA into the form, select a reader voice, and click \"Read\".\nSome of the voices seem a bit odd. I settled on \"Brian\" for British\nEnglish, and it seems fine.

                                                            By design, X11 applications can't access window or screen contents\nfor wayland clients. This is fine in principle, but it breaks screen\nsharing in tools like Discord, MS Teams, Skype, etc and more.

                                                            \nHello Hacker Public Radio, Brian in Ohio here. I am out from under my\nrock and this episode is about an old file format that despite its age\nis still in use in many places today.

                                                            \n

                                                            That format is the Intel Hex format. What is this format? Glad you\nasked.

                                                            \n

                                                            From the book of knowledge we read,

                                                            \n

                                                            Intel hexadecimal object file format, Intel hex format or Intellec\nHex is a file format that conveys binary information in ASCII text\nform.

                                                            \n

                                                            If you have ever programmed an arduino board the file that is used to\nprogram the board.

                                                            \n

                                                            The file generated by the arduino eye dee eee is an intel hex\nfile.

                                                            \n

                                                            The format consists of any number of lines, called records.

                                                            \n

                                                            Intel HEX consists of lines of ASCII text that are separated by line\nfeed or carriage return characters or both.

                                                            \n

                                                            Each text line contains uppercase hexadecimal characters that encode\nmultiple binary numbers.

                                                            \n

                                                            The binary numbers may represent data, memory addresses, or other\nvalues, depending on their position in the line and the type and length\nof the line.

                                                            \n

                                                            Each text line is called a record.

                                                            \n

                                                            A record consists of six fields that appear in order from left to\nright

                                                            \n
                                                              \n
                                                            1. Start code, one character, an ASCII colon.
                                                              2. \n
                                                            2. Byte count, indicating the number of bytes in the data field.
                                                              3. \n
                                                            3. Address, four hex digits, representing the 16-bit beginning memory\naddress offset of the data.
                                                              4. \n
                                                            4. Record type two hex digits, 00 to 05, defining the meaning of the\ndata field.
                                                              5. \n
                                                            5. Data, a sequence of bytes of data
                                                              6. \n
                                                            6. Checksum, a computed value that can be used to verify the record has\nno errors.
                                                              7. \n
                                                            \n

                                                            An end of file record must occur exactly once per file in the last\nrecord of the file. The byte count is 00, the address field is typically\n0000 and the data field is omitted.

                                                            \n

                                                            A record's checksum byte is the two's complement of the least\nsignificant byte of the sum of all decoded byte values in the record\npreceding the checksum.

                                                            \n

                                                            It is computed by summing the decoded byte values and extracting the\nleast significant byte of the sum, and then calculating the two's\ncomplement of the sum, by inverting its bits and adding one.

                                                            \n

                                                            I have included in the show notes an example of a record with pipes\nused to break up the line.

                                                            \n

                                                            Hope you enjoyed the espeak episode.

                                                            \nWhy unsubscribe? 1. For the environment. It is dirt cheap to spam\ne-mails around. But the amount adds up in electricity and traffic. 2.\nFor your own privacy. 2a. If you use a commercial mail provider that\nscans your mails, then each time you get one of those, it is scanned and\nthe profile on you grows. 2b. In case the sender of the newsletter is\never hacked (chances are it will at a certain point), your address will\nleak to the crackers. 2c. The sender has your address and can (and\nprobably will) trade it for money. In an ideal world (we all like to\nthink that hope dies last) they delete your address when you\nunsubscribe. If not, it's probably a violation of GDPR.

That is exactly what is going on this show. First there is\nsome useful information about sextortion, the forms it manifests in and\nconsequences it can have in real life, that's the good stuff. Then comes\nthe bad and the straight-out ugly bit. While the speaker starts of with\na pretty factual analysis, eventually he slides into a very much\nopinionated stance against any form of digital eroticism. Don't do\n***** kids! Where have we heard that before, right?\nSeriously, if you are an adult having a problem with the fact that\npeople exchange nudes in their sexual discovery journey then that is\njust your own moral problem, do not project that on the rest of the\nworld please. People have done that about sex, drugs, music, religious\nbelieves, cultural habits, and pretty much everything we humans design\nto entertain ourselves and to carry out our identity into the world.\nSaying \"Don't do that\" really is totally random moral stance since what\nis found to be offensive in your part of the world might be totally\ninnocent behavior where I live and vice versa. So, again, because\nrepetition seems to work for Coca-Cola: don't project your own random\nmoral objections onto the world. They are legit, they are rightfully\nyours to keep. But don't try to push them further than that, because\nthat's just randomly stupid.

                                                            In this episode I continue the series \"Today I learnt..\" which was\nstarted by Dave\nMorriss in HPR 4002

                                                            I mention that I first tried to remove the password from my pdf using\nthe excellent pdf manipulation program Okular recommended to me by Dave\nMorriss.

                                                            \n

                                                            After some googling I found the following solution\nto my password protected PDF.

                                                            \n

                                                            The command line program I used to remove the password from my pdf\nwas qpdf.

                                                            In his lonely man cave, a HPR Janitor is visited by the ghost of\nprocrastination. Two years later he is again visited, but this time by\nthe ghost of desperation. And then finally by the ghost of rambling.

                                                            Today we learn about AC and DC voltage, about Ohms Law and how to\nwire up a LED to a USB connector.

                                                            \n

                                                            A long rambling show which in the end came down to using ohms law to\nfind the value of the resister.

                                                            \n

                                                            Knowing any 2 of the 3 values in Ohms law will give us the resistor\nwe need.

                                                            \n

                                                            The current will be the same, so we can just measure, and it turns\nout to be 22 mA (milliamperes) or 0.022 amp. This is measured in Amps,\nand has the symbol I

                                                            \n

                                                            The voltage we need to use up is 2 volts as we are going from 5 Volts\nUSB AC Adapter to 3 Volts used by the two AA battery in series. Giving\nus 2 Volts with unit of V.

                                                            \n

                                                            We can then find the Resistance measured in Ohms by dividing 2 Volts,\nby 0.022 Amps to give us 90 Ohms of Resistance.

                                                            \n

                                                            The V is always on top of the triangle with I and R underneath.

                                                            \n

                                                            So not having a 90 Ohm resistor a 100 Ohm would work just as\nwell.

                                                              • Within a capitalist economic system, commodification is the\ntransformation of things such as goods, services, ideas, nature,\npersonal information, people or animals into objects of trade or\ncommodities. A commodity at its most basic, according to Arjun\nAppadurai, is \"anything intended for exchange,\" or any object of\neconomic value.

                                                              • Attention economics is an approach to the management of information\nthat treats human attention as a scarce commodity and applies economic\ntheory to solve various information management problems. According to\nMatthew Crawford, \"Attention is a resource-a person has only so much of\nit.\" Thomas H. Davenport and John C. Beck add to that definition:

This phenomenon is distinct from government\nsurveillance, though the two can reinforce each other. The concept of\nsurveillance capitalism, as described by Shoshana Zuboff, is driven by a\nprofit-making incentive, and arose as advertising companies, led by\nGoogle's AdWords, saw the possibilities of using personal data to target\nconsumers more precisely.

                                                            The playerctl utility controls MPRIS-enabled media players. In\naddition to offering play, pause and stop control, playerctl also offers\nprevious and next track support, the ability to seek backwards and\nforwards in a track, and volume control. playerctl also supports\ndisplaying metadata (e.g., artist, title, album) for the current track,\nand showing the status of the player.

                                                            \n

                                                            Players that can be controlled using playerctl include audacious(1),\ncmus(1), mopidy(1), mpd(1), quodlibet(1), rhythmbox(1), vlc(1) and\nxmms2(1). However, any player that implements the MPRIS interface\nspecification can be controlled using playerctl including web\nbrowsers.

                                                            A circadian rhythm (/sərˈkeɪdiən/), or circadian cycle, is a natural\noscillation that repeats roughly every 24 hours. Circadian rhythms can\nrefer to any process that originates within an organism (i.e.,\nendogenous) and responds to the environment (is entrained by the\nenvironment). Circadian rhythms are regulated by a circadian clock whose\nprimary function is to rhythmically co-ordinate biological processes so\nthey occur at the correct time to maximise the fitness of an individual.\nCircadian rhythms have been widely observed in animals, plants, fungi\nand cyanobacteria and there is evidence that they evolved independently\nin each of these kingdoms of life.

Some of those shows\nwere unedited and had some dead air that I wanted to remove. It\ntook me a few tries, but I eventually figured out how to truncate\nsilence with sox

Before the\nsansa clips came out, my favorite was the sansa e200 series https://en.wikipedia.org/wiki/Sansa_e200_series They\ncould run the alternative firmware, rockbox. https://www.rockbox.org/\nI remember wasting hours playing frozen bubble on my mp3 player.

                                                            There were a few times where I would run out of episodes to listen\nto. So I decided to add some podcasts to my work iPhone. For most of the\ntime I worked there, I would take my sansa with me and listen to every\nthing on it. Then if I ran out, I had my phone with me, so I would\nlisten to podcasts on it.

                                                            \n
                                                            \n

                                                            This process meant I had 2 sets of podcasts - provided by mashpodder\n- iPhone app.

                                                            \n
                                                            \n

                                                            I kept this practice of having 2 podcast sources for a few years, but\nI eventual stopped using the sansa. Phones were getting better, and the\nsansa devices were getting harder to find.

                                                            \n
                                                            \n

                                                            I wanted to start listening to my bashpodder podcasts on my phone. I\nlooked for a few file transfer solutions, but eventually settled on\nmaking my own RSS feed of files I had downloaded.

                                                            \n
                                                            \n

                                                            I found a python script that would take a directory listing of mp3s\nand build a RSS feed. Now I had a cron job that would - download -\nprocess with sox - create the RSS feed - rsync RSS XML file on podcast\nfiles to a VPS

                                                            \n

                                                            \n

                                                            I used a VPS so I could download new episodes to my phone from\nanywhere. After a while, I experimented with using a AWS S3 to host the\nfiles. I stopped using S3 when the free tier ran out, and I started\ngetting charged for storage and bandwidth.

                                                            \n
                                                            \n

                                                            Eventually, when I started working at home I no longer needed the RSS\nfeed to be available from anywhere. So I just started using a http\nserver in my home lab to host my RSS feed and files. I can update my\nphone with the files I download and process as long as I am on my home\nnetwork

                                                            \n
                                                            \n

                                                            Also, one other change I made at some point was switching from\nbashpodder to mashpodder. There were a few podcast that bashpodder was\nnot able to parse.

                                                            Today, I listen to podcasts via antenna pod Most of of the podcasts I\nsearched for and subscribed to via the app. There are still a few\npodcasts that I get via mashpodder and pre-process with sox. Since the\nphone app is good at altering the tempo (I like 2x), I no longer have to\nuse sox for speeding up. But I still use sox for leveling the audio and\ntruncating silence.

                                                            \n

                                                            My tendency is to have the podcasts that are produced by\nstudios/companies via the app and podcasts produced by enthusiasts via\nmashpodder/sox

                                                            Here is a quick overview of the NAS systems/technology I use today\nand what I have used in the past. Some NAS systems don’t have all the\nfeatures you want but today it’s becoming easier to make them do it with\na few configurations. Overall, NAS technology has grown over the years\nand it’s blurred the lines in what we use to think of individual systems\nnow bundled up into single devices.

                                                            \n

                                                            This is not a good overview of gdb, I don't think, for\nthat I would recommend episode\n415 on Klaatu's Gnu World Order podcast.

                                                            \n

                                                            The program that we build up to is this:

                                                            \n
                                                            // file: main.c\n#include <stdio.h>\n#include <string.h>\n\nvoid greet(char* greeting)\n{\n-    int end = strlen(greeting);\n+    int end = strlen(greeting) - 1;\n    if (greeting[end] == '\n')\n        printf("%s", greeting);\n    else\n        printf("%s\n", greeting);\n}\n\nint main ()\n{\n    greet( "Hello world!\n");\n    return 0;\n}
                                                            \n

                                                            Where we use gdb to find out that we are checking one character past\nthe end in the if-condition rather than the last character, this then\nresults in a double new-line.

                                                            \n

                                                            Once the debugger is launched within vim, termdebug offers a few ways\nto control the debugging, namely:

                                                            \n

                                                            :Source - focus on source window. :Gdb -\nfocus on debugger window. :Program - focus on program\noutput window :Break - introduce a break point in line\nunder the cursor (in the source window) :Clear - clear the\nbreak point in the line under the cursor. :Evaluate - show\nthe value of the expression under the cursor.

                                                            \n

                                                            ... And a good deal more, if you're interested just have a gander at\n:help termdebug.

                                                            \n

                                                            I hope this helps someone make their debugging experience slightly\nless painful, as it has helped me recently :)

                                                            Alright, enough of me poorly impersonating a pirate. As you may or\nmay not know, based on comments in one or more of my previous episodes,\nI dabble a bit in clock repair. Specifically, mechanical clocks, powered\nby springs or gravity. My grandfather was a clockmaker, and I remember\nsitting, as still and quietly as I could, in his shop watching him work.\nI was fascinated, but I could not ask any questions, make any noise, or\ntouch anything at risk of being told to leave. So, I learned very\nlittle, but it did plant a seed deep inside me which would flourish many\nyears after my grandfather passed away.

                                                            \n

                                                            I plan to do a series about mechanical clocks and some of my\nexperiences with clock repair in upcoming months. This has been\nsimmering on the back burner for quite a while as I debated if it would\nreally be of interest to hackers. My mind creates stories of listeners\nshouting “Oh for crying out loud! First six episodes about plumbing and\nnow clocks? Get to something interesting!” However, I am pressing on. If\nyou like this episode and want more in the series, please leave a\ncomment. If you would prefer other types of content on HPR, then skip\nthe rest of this episode and record one more suited to your desires or\ndetailing what you would like to hear and why.

                                                            Also, you will probably hear the ticking (and maybe striking) of\nvarious different clocks in the background of this recording. My new\nhome office space is also the home for close to a dozen clocks in\nvarious states of repair. It is challenging to remove their sounds from\nthe recording, and given the subject matter of this series, I am not\neven going to try to remove them.

                                                            \n

                                                            Back to the topic. A couple of years ago, I purchased a very\ninexpensive box of assorted clocks and clock parts from a local seller.\nThese were in various states of disrepair. One item in the advertisement\nfor this box immediately caught my eye. It was a brass Urgos brand\n“Ship’s Bell” clock. This timepiece was literally dripping with oil, but\nseemed to be intact, and I started working on it. In a later podcast, I\nwill describe my approach to items like this and what is involved in\ninitially cleaning and evaluating them. Due to life challenges, it took\nme over a year to get this clock reassembled and working.

                                                            \n

                                                            With this clock, I learned that ship’s bells do not strike a normal\nhour count like traditional striking clocks. Instead, their strike\ndirectly relates to the time of an historic ship’s watch schedule.\nAccording to “The Ship’s Bell”, an article from Naval History and\nHeritage Command (https://www.history.navy.mil/browse-by-topic/heritage/customs-and-traditions0/the-ship-s-bell.html),\nearly shipboard timekeeping was done through the use of a half-hour\nglass. The job for one of the ship’s boys was to watch the glass, turn\nit when it ran out, and then strike the ship’s bell so all onboard would\nbe aware of the time every half hour.

                                                            \n

                                                            On sea vessels, various persons on duty “Keep watch” at, or around,\ntheir station. These include the “Lookout” who was constantly “watching”\nall around the ship to ensure there was no danger and to alert of any\nsightings of land or other vessels. (https://en.wikipedia.org/wiki/Watchkeeping )

                                                            \n

                                                            The ship’s bell had many other uses beyond timekeeping, and those are\ndescribed in detail in the previously mentioned Naval History article.\nWith all this bell ringing, patterns were developed. For timekeeping,\nthis basically broke down to a specific pattern of incrementing strikes\nevery half hour, throughout the ship’s watch. Each watch is a 4 hour\nlong shift, the first five of which are broken down as follows:

                                                            The remaining 4 hours are broken up into two “Dog Watches”, but those\nare outside the scope of this discussion. You can learn more about these\ndetails in Tom Burden’s article titled “Ship’s Bell Time” and found at\nhttps://www.westmarine.com/west-advisor/Ships-Bell-Time.html

                                                            Ship’s bell strikes increment every half hour. At the beginning/end\nof a 4-hour watch, the bell strikes 8 times, in groups of 2 strikes with\na tiny pause in between. Here is an example from my (now working) ship’s\nbell clock.

                                                            \n
                                                            {ding}{ding} pause {ding}{ding} pause {ding}{ding} pause {ding}{ding} pause
                                                            \n

                                                            One half hour into the watch, the ship’s bell will sound a single\nstrike

                                                            \n

                                                            One hour into the watch, the ship’s bell will sound two strikes

                                                            \n

                                                            An hour and an half into the watch, the ship’s bell will sound three\nstrikes in the following pattern:

                                                            \n
                                                            {ding}{ding} {pause} {ding}
                                                            \n

                                                            At the two hour mark, there will be four strikes, following that same\npattern:

                                                            \n
                                                            {ding}{ding} {pause} {ding}{ding}
                                                            \n

                                                            Etc… I will not list all of these, but you get the idea. Because the\nstrikes are paired in groups of two, an even number of strikes denotes\nthe top of the hour, and it is easy to count the number of pairs (1, 2,\n3, or 4). If the bells end in a single strike (odd number total), you\nknow it is the bottom of the hour.

                                                            \n

                                                            It seems strange at first, but it can be easily learned in a short\namount of time. And now, the phrase I used at the beginning of this\npodcast, “Eight bells and all’s well” should make sense. Eight bells\nindicates the end of the watch, and an individual on watch duty is\nstating that their shift is finished and there was nothing to\nreport.

                                                            \n

                                                            I hope that you have enjoyed this episode. Your feedback is\nencouraged, through comments and especially by recording your own HPR\nepisode.

TEC-1 was designed\nspecifically to get the ordinary bloke involved with computers.

                                                            • The ability to use SSH

                                                            \n

                                                            Once we have SSH'd into the Pi the first thing we should do is update it:

                                                            \n
                                                            sudo apt update && sudo apt upgrade -y
                                                            \n

                                                            Then we need to install the Pi-hole software itself. We can do this with the command:

                                                            \n
                                                            curl -sSL https://install.pi-hole.net | bash
                                                            \n

                                                            This will start an installation wizard

                                                            \n

                                                            Once this has completed, it is recommended that you set a new admin password:

                                                            \n
                                                            pihole -a -p

                                                            I talk about my migration from Adobe Photoshop Elements to digiKam as\nphoto catalog software, or DAM Digital Asset Management as it often is\nreferred to nowadays.

                                                            \n

                                                            My latest was release 14 which I bought 2015, which also was when I\nmigrated from Windows to macOS.

                                                            \n

                                                            Photoshop Elements is without hesitation a good software. One major\ndrawback is that is a proprietary software from which I cannot export\ndata on my conditions.

                                                            \n

                                                            After a few of years on release 14 the geotagging stopped working.\nThe error message told that this was caused by a change by Google. Adobe\nPhotoshop Elements had a fix for this error - but only incorporated in\nthe next release of the software. No fix was planned for my release. So\nto get geotagging working again, I would have to buy a new release.

                                                            \n

                                                            I also got problem that it now and then crashed and needed to be\nrestarted. Something needed to be done.

                                                            \n

                                                            I considered if I should buy a new release of Photoshop Elements or\nchange to any other software. At the same time I also became more\nattracted to Linux. I also became more interested in free and open\nsoftware.

                                                            \n

                                                            A big drawback with changing to something else than Adobe is that I\nmost certainly will loose some of the work I have put into photos in\nPhotoshop Elements.

                                                            \n
                                                              \n

                                                            1. The Photo editing data and raw conversion settings for individual\nphotos will be lost. This is almost impossible to migrate between\nsoftware. What can be done is to save what I have edited as new photos.\nI am fine with this, it will not stop me from changing\nsoftware.

                                                              2. \n

                                                            2. Meta data is very important to me. Meta data contains not only\ninformation about the shooting from the camera itself. But also my tags,\ndescription texts and more I had added in Photoshop Elements. Meta data\nalso includes face tagging. This goes both for digital camera photos as\nwell as digitized analog photos.

                                                              3. \n

                                                              1. Preferable free and open source
                                                                2. \n
                                                              2. Available on multiple platforms, in particular available on macOS\nand Linux
                                                                3. \n
                                                              3. That meta data can be migrated including face tagging
                                                                4. \n

                                                            \n

                                                            The one that I found to best meet my criteria is digiKam.

                                                            \n

                                                            DigiKam is mostly known for its catalog capabilities. But digiKam\nalso includes import and export functions as well as raw conversion and\nphoto editing.

                                                            \n

                                                            My migration.

                                                            \n

                                                            Photoshop Elements stores the data in a data base. It is possible to\nexport metadata to files and sidecars. But not all data. Face tagging\ncannot be exported. The name of the person can be exported but not the\ncoordinates of the face tag which only is stored in the data base.

                                                            \n

                                                            The data base itself cannot be read by other software, except by\nAdobe software: Adobe Lightroom Classic can import the data from\nPhotoshop Elements data base into its own data base. This was very\nimportant for my migration success. Lightroom can export also the face\ntagging.

                                                            \n

                                                            I discovered an issue with the time- and datestamps. In Photoshop\nElements it is possible to give incomplete date and time, for example\nonly state the year if I do not know all details. Already Lightroom had\nproblem to interpret this information correctly and I had to implement a\nworkaround with tags. In general, several time and date attributes exist\nand it is something to understand what is what and how each of the is\ndefined, displayed and managed in the software.

                                                            \n

                                                            From Lightroom Classic I exported meta data including face tags to\nfiles and sidecars.

                                                            \n

                                                            And migration to digiKam worked good enough. I still have access to\nmy Photoshop Elements database if I want to go back and check\nanything.

                                                            \n

                                                            My next step was to migrate from digiKam on macOS to digiKam on\nLinux. This migration was relatively easy. My current settings in\ndigiKam is to always write data to sidecars, in addition to the digiKam\ndata bases. So I copied photo files and sidecars from macOS to Linux. I\ntook the opportunity to rearrange my folder structure. Then I imported\ninto digiKam and digiKam built new data bases in Linux based on photos\nand sidecars.

                                                            The Pomodoro Technique is a time management method developed by\nFrancesco Cirillo in the late 1980s. It uses a kitchen timer to break\nwork into intervals, typically 25 minutes in length, separated by short\nbreaks. Each interval is known as a Pomodoro, from the Italian word for\ntomato, after the tomato-shaped kitchen timer Cirillo used as a\nuniversity student.

Once the data had been downloaded, the NCSC took the lead\nin systematically categorising and triaging all documents relevant to\nthe Federal Administration. The results showed that the volume of data\nrelevant to the Federal Administration comprised around 65,000\ndocuments, or approximately 5% of the total published data set. The\nmajority of these files belonged to Xplain (47,413) with a share of over\n70%; around 14% (9,040) belonged to the Federal Administration. Around\n95% of the Federal Administration’s files belonged to the administrative\nunits of the Federal Department of Justice and Police (FDJP): the\nFederal Office of Justice, Federal Office of Police, State Secretariat\nfor Migration and the internal IT service centre ISC-FDJP. With just\nover 3% of the data, the Federal Department of Defence, Civil Protection\nand Sport (DDPS) is slightly affected and the other departments are only\nmarginally affected in terms of volume.

I thought this was very clever. Haven't seen this\non modern buses or trams, perhaps because they don't meet modern safety\nregulations.

                                                            In hpr4071 I talked about my migration from Adobe Photoshop Elements\nand Lightroom to digiKam.

                                                            \n

                                                            Today I will give you some suggestions to getting started with\ndigiKam, based on my experience and my opinion.

                                                            \n

                                                            You find the digiKam website at https://www.digikam.org/.

                                                            \n

                                                            On the documentation page you find a good and exhaustive\ndocumentation. The big user manual can be read online or downloaded as\nan epub book. I suggest you browse the manual before you install\ndigiKam.

                                                            \n

                                                            My second suggestion is that you go to the Support page on the\ndigiKam site and look at the Mailing List Subscription section. You can\nbrowse the mailing list archive online. But I really recommend you to\nalso join the mailing list. It is a very active mailing list where also\nthe main developers participates actively. Many questions are specific\nand may not be of interest to you. But I have found that I learn a lot\nabout digiKam, its capabilities and other ways of working with photos\nthan I have thought of. Of course I also learn about issues. I have\nasked some questions myself and also contributed with answers. I highly\nrecommend you to join the mailing list.

                                                            \n

                                                            Thirdly, before you install digiKam, I suggest you copy a couple of\nyour photos into a new sample folder. When you start digiKam for the\nfirst time a guide starts to help you to configure initial settings. One\nconfiguration is to tell digiKam where your photos are located. I\nsuggest you use this sample folder only. Later on you add your real\nphoto folders and you can also at the same screen delete the sample\nfolder from digiKam. I suggest this because then you can consider\nsettings in more detail first which includes the settings for meta data\nimport to digiKam.

                                                            Forthly, consider also where you want to store the digiKam databases.\nMyself, I created a folder for them at the top level of my home catalog.\nBut you can store them wherever you want to.

                                                            \n

                                                            Install digiKam. Go to the digiKam settings. There are a lot of\nsettings. I will focus only on meta data settings.

                                                            \n

                                                            DigiKam stores what you do in its own databases. That is mandatory.\nIn the settings, it is possible to select what should be written to\nmetadata and not. Meta data settings also have settings for associated\nfiles, which most of all is about xmp side cars.

                                                            \n

                                                            You can select that digiKam should read from associated files. This\nis important to decide before your photo collection is imported into\ndigiKam. If you forget, it is possible to read meta data again after you\nchange settings.

                                                            \n

                                                            Then there is an option if digiKam should write to side cars or not.\nAnd if yes, if it should write to both side cars and the object, or only\nif the object is write protected.

                                                            \n

                                                            Next I want to highlight the tick box if Associated files should be\ncompatible with commercial programs. This needs further\nexplanation:
                                                            \n

                                                            \n
                                                              \n
                                                            • Default in digiKam is to have separate xmp side cars for each type\nof photo file. For example, if you have a photo stored both as jpg and\nraw, they will have separate side cars. This indeed has its advantages\nbut is in my knowledge not according to xmp side car standard. According\nto standard, which digiKam refers to as commercial, the jpg and raw\nshare the same sidecar. For example Adobe Lightroom uses the commercial\nmethod.
                                                              • \n
                                                            \n

                                                            Examples to clarify:

                                                            \n
                                                              \n
                                                            • DigiKam side car file syntax: photo1.jpg.xmp and\nphoto1.raw.xmp.
                                                              • \n
                                                            • Standard/commercial file syntax: photo1.xmp.

                                                            \n

                                                            I highly recommend you to spend an hour or two to review all\nsettings, not only meta data, before you start to use digiKam for your\nreal photos. If there is something you do not understand, go to the\ndocumentation and do not hesitate to consult the digiKam mailing\nlist.

                                                            Home automation or domotics is building automation for a home. A home\nautomation system will monitor and/or control home attributes such as\nlighting, climate, entertainment systems, and appliances. It may also\ninclude home security such as access control and alarm systems.

                                                            \n

                                                            The phrase smart home refers to home automation devices that have\ninternet access. Home automation, a broader category, includes any\ndevice that can be monitored or controlled via wireless radio signals,\nnot just those having internet access. When connected with the Internet,\nhome sensors and activation devices are an important constituent of the\nInternet of Things (\"IoT\").

                                                            \n

                                                            A home automation system typically connects controlled devices to a\ncentral smart home hub (sometimes called a \"gateway\"). The user\ninterface for control of the system uses either wall-mounted terminals,\ntablet or desktop computers, a mobile phone application, or a Web\ninterface that may also be accessible off-site through the Internet.

                                                            I tried this out a few years ago, but after a lot of frustration with\nconfiguration of esp32 arduinos, and raspberry pi's I left it be.\nRecently inspired by colleagues in work, I decided to get back into it\nand my initial tests show that the scene has much improved over the\nyears.

                                                            Home Assistant is free and open-source software for home automation,\ndesigned to be an Internet of things (IoT) ecosystem-independent\nintegration platform and central control system for smart home devices,\nwith a focus on local control and privacy. It can be accessed through a\nweb-based user interface, by using companion apps for Android and iOS,\nor by voice commands via a supported virtual assistant, such as Google\nAssistant or Amazon Alexa, and their own \"Assist\" (built-in local voice\nassistant).

                                                            The Home Assistant software application is installed as a computer\nappliance. After installation, it will act as a central control system\nfor home automation (commonly called a smart home hub), that has the\npurpose of controlling IoT connectivity technology devices, software,\napplications and services from third-parties via modular integration\ncomponents, including native integration components for common wireless\ncommunication protocols such as Bluetooth, Thread, Zigbee, and Z-Wave\n(used to create local personal area networks with small low-power\ndigital radios). Home Assistant as such supports controlling devices and\nservices connected via either open and proprietary ecosystems as long\nthey provide public access via some kind of Open API or MQTT for\nthird-party integrations over the local area network or the\nInternet.

For example, a product by\nPhilips called Hue would use the Philips Hue term integration and allow\nHome Assistant to talk to the hardware controller Hue Bridge. Any Home\nAssistant compatible term devices connected to the Hue Bridge would\nappear in Home Assistant as devices.

                                                            Once an term integration has been added, the hardware and/or data are\nrepresented in Home Assistant as devices and\nentities.

                                                            \n

                                                            Entities are the basic building blocks to hold data in Home\nAssistant. An term entity represents a term sensor, actor, or function\nin Home Assistant. Entities are used to monitor physical properties or\nto control other term entities. An term entity is usually part of a term\ndevice or a term service. Entities have term states.

                                                            \n

                                                            Devices are a logical grouping for one or more term entities. A term\ndevice may represent a physical term device, which can have one or more\nsensors. The sensors appear as entities associated with the term device.\nFor example, a motion sensor is represented as a term device. It may\nprovide motion detection, temperature, and light levels as term\nentities. Entities have states such as detected when motion is\ndetected and clear when there is no motion.

                                                            • Dashboards\ncan show a state of an term entity. For example, if a light is on or\noff.
                                                              • \n
                                                            • An automation can be triggered from a\nstate change on an term entity. For example, a motion sensor entity\ndetects motion and triggers a light to turn on.
                                                              • \n
                                                            • A predefined color and brightness setting for a light saved as a scene.
                                                              • \n

                                                            \n

                                                            An area in Home Assistant is a logical grouping of term devices and\nterm entities that are meant to match areas (or rooms) in the physical\nworld: your home. For example, the living room area groups\ndevices and entities in your living room. Areas allow you to target\nservice calls at an entire group of devices. For example, turning off\nall the lights in the living room. Locations within your home such as\nliving room, dance floor, etc. Areas can be assigned to term floors.\nAreas can also be used for automatically generated cards, such as the Area card.

                                                            A set of repeatable term actions that can be set up to run\nautomatically. Automations are made of three key components:

                                                            \n

                                                            1. Triggers - events that start an term automation. For example, when\nthe sun sets or a motion sensor is activated.
                                                              2. \n
                                                            2. Conditions - optional tests that must be met before an term action\ncan be run. For example, if someone is home.
                                                              3. \n
                                                            3. Actions - interact with term devices such as turn on a light.
                                                              4. \n

                                                            Similar to term automations, scripts are repeatable term actions that\ncan be run. The difference between term scripts and term automations is\nthat term scripts do not have triggers. This means that term scripts\ncannot automatically run unless they are used in an term automations.\nScripts are particularly useful if you perform the same term actions in\ndifferent term automations or trigger them from a dashboard. For\ninformation on how to create term scripts, refer to the scripts\ndocumentation.

                                                            Scenes allow you to create predefined settings for your term devices.\nSimilar to a driving mode on phones, or driver profiles in cars, it can\nchange an environment to suit you. For example, your watching\nfilms term scene may dim the lighting, switch on the TV and\nincrease its volume. This can be saved as a term scene and used without\nhaving to set individual term devices every time.

Add-ons are usually apps that can\nbe run with Home Assistant but provide a quick and easy way to install,\nconfigure, and run within Home Assistant. Add-ons provide additional\nfunctionality whereas term integrations connect Home Assistant to other\napps.

                                                            Summary

                                                            \n

                                                            There is a formula consisting of 6 building blocks that can help\ngenerate high quality outputs from ChatGPT and Google Bard: task,\ncontext, exemplars, persona, format, and tone.

                                                            \n

                                                            The order of importance for the building blocks is task first, then\ncontext, with the others being optional but helpful.

                                                            \n

                                                            The task should clearly articulate the end goal using an action verb\nlike \"generate\" or \"analyze\".

                                                            \n

                                                            Context provides relevant background information to constrain\npossibilities.

                                                            \n

                                                            Exemplars like examples or frameworks included in the prompt can\nimprove output quality.

                                                            \n

                                                            The persona allows specifying who ChatGPT should be, like a job\nrecruiter.

                                                            \n

                                                            The format specifies how the output should be structured, like an\nemail or bullet points. Tone provides keywords to set the feeling, like\n\"friendly\" or \"serious\".

                                                            \n

                                                            I hope this email finds you well. I wanted to touch base on a\ncritical aspect of our Security Information and Event Management (SIEM)\nprocess that could significantly enhance our efficiency.

                                                            \n

                                                            TL;DR: We need to ensure that stakeholders understand their data and\nhave clear objectives before we initiate the SIEM onboarding process.\nThis will prevent the team from spending excessive time onboarding data\nthat may not meet the intended use cases or for which the requester has\nno actionable plan.

                                                            \n

                                                            During our recent SIEM onboarding efforts, we've encountered several\ninstances where considerable time and resources were invested in\nintegrating data sources, only to discover that the requesters were\nunclear about their objectives or the data did not fulfill their\nanticipated needs. For example, last month, the team dedicated over 40\nhours to onboarding a new data source for the marketing department.\nAfter completion, it became apparent that the marketing team was unsure\nhow to leverage this data for threat detection or compliance reporting,\nrendering the effort less effective.

                                                            \n

                                                            To address this, I propose we implement a preliminary consultation\nphase for each SIEM onboarding request. In this phase, requesters must\narticulate: - The specific security or compliance questions they aim to\nanswer with the data. - How they intend to use the data within the SIEM\nenvironment. - Any particular data formats or schemas they anticipate\nwill be necessary.

                                                            \n

                                                            By doing so, we can align our onboarding efforts with the actual\nneeds and ensure that every hour spent is towards enhancing our security\nposture and providing actionable insights.

                                                            \n

                                                            I believe this approach will not only save time but also empower our\nstakeholders to make better-informed decisions regarding their security\ndata needs.

                                                            Looking forward to your thoughts on this.

                                                            1. Here are 8 basic tips that work for me, followed by one super\nsecret tip that I recently discovered.

                                                              2. \n

                                                            2. Consistency is important. Don’t mix photos from 10 years ago with\nnew ones. Faces change, people lose weight or gain weight and it all\njust lowers fidelity.

                                                              3. \n

                                                            3. Avoid big expressions, especially ones where the mouth is\nopen.

                                                              4. \n

                                                            4. It is much easier to train if the hair doesn't change much. I\ntried an early model of a woman using photos with hair up, down, in\nponytail, with a different cut, etc. It seems like it just confused\nSD.

                                                              5. \n

                                                            5. Avoid selfies (unless you ONLY use selfies.) There is MUCH more\nperspective distortion when the camera is that close. For optimal\nresults, a single camera with a fixed lens would be used, and all photos\nshould be taken at the same distance from the subject. This usually\nisn't possible, but at least avoid selfies because they cause major face\ndistortion.

                                                              6. \n

                                                            6. Full body shots are not that important. Some of the best models I\ntrained used only 15 photos cropped to the head / shoulder region. Many\nof these were full body shots, but I cropped them down. SD can guess\nwhat the rest of the body looks like, and if not, just put it in the\nprompts. The only thing hard to train is the face, so focus on\nthat.

                                                              7. \n

                                                            7. I no longer use any profile shots as they don’t seem to add\nvalue. I like to have a couple looking slightly left and a couple\nlooking slightly right (maybe 45 degrees.) All the rest can be straight\nat the camera. Also, try to avoid photos taken from really high or low\nangles.

                                                              8. \n

                                                            8. If possible, it’s good to have some (but not all) of the photos\nbe on a very clean background. On my last batch, I used an AI background\nremoval tool to remove the background from 1/4 of the photos and\nreplaced it with a solid color. This seemed to improve results.

                                                              9. \n

                                                            9. Careful with the makeup. It should be very consistent across all\nthe photos. Those cool “contour” effects that trick our eyes, also trick\nSD.

                                                              10. \n

                                                            Introduction

                                                            \n

                                                            This is the start of a short series about the JSON data format, and how\nthe command-line tool jq\ncan be used to process such data. The plan is to make an open series to\nwhich others may contribute their own experiences using this tool.

                                                            \n

                                                            The jq command is described on the GitHub page as follows:

                                                            \n
                                                            \n

                                                            jq is a lightweight and flexible command-line JSON processor

                                                            \n
                                                            \n

                                                            …and as:

                                                            \n
                                                            \n

                                                            jq is like sed for JSON data - you can use\nit to slice and filter and map and transform structured data with the\nsame ease that sed, awk, grep and\nfriends let you play with text.

                                                            \n
                                                            \n

                                                            The jq tool is controlled by a programming language\n(also referred to as jq), which is very powerful. This\nseries will mainly deal with this.

                                                            \n

                                                            JSON (JavaScript Object\nNotation)

                                                            \n

                                                            To begin we will look at JSON itself. It is defined on\nthe Wikipedia page\nthus:

                                                            \n
                                                            \n

                                                            JSON is an open standard file format and data\ninterchange format that uses human-readable text to store and transmit\ndata objects consisting of attribute–value pairs and arrays (or other\nserializable values). It is a common data format with diverse uses in\nelectronic data interchange, including that of web applications with\nservers.

                                                            \n
                                                            \n

                                                            The syntax of JSON is defined by RFC 8259 and by\nECMA-404.\nIt is fairly simple in principle but has some complexity.

                                                            \n

                                                            JSON’s basic data types are (edited from the Wikipedia page):

                                                            \n
                                                              \n

                                                            • Number: a signed decimal number that may contain a\nfractional part and may use exponential E notation, but cannot include\nnon-numbers. (NOTE: Unlike what I said in the audio,\nthere are two values representing non-numbers: 'nan' and\ninfinity: 'infinity'.

                                                              • \n

                                                            • String: a sequence of zero or more Unicode characters.\nStrings are delimited with double quotation marks and support a\nbackslash escaping syntax.

                                                              • \n

                                                            • Boolean: either of the values true or\nfalse

                                                              • \n

                                                            • Array: an ordered list of zero or more elements, each of\nwhich may be of any type. Arrays use square bracket notation with\ncomma-separated elements.

                                                              • \n

                                                            • Object: a collection of name–value pairs where the names\n(also called keys) are strings. Objects are delimited with curly\nbrackets and use commas to separate each pair, while within each pair\nthe colon ':' character separates the key or name from its\nvalue.

                                                              • \n

                                                            • null: an empty value, using the word\nnull

                                                              • \n
                                                            \n

                                                            These are the basic data types listed above (same order):

                                                            From the Wikipedia page:

                                                            \n
                                                            \n

                                                            jq was created by Stephen Dolan, and released in October\n2012. It was described as being “like sed for JSON data”. Support for\nregular expressions was added in jq version 1.5.

                                                            This tool is available in most of the Linux repositories. For\nexample, on Debian and Debian-based releases you can install it\nwith:

                                                            \n

                                                            There is a detailed manual describing the use of the jq\nprogramming language that is used to filter JSON data. It can be found\nat https://jqlang.github.io/jq/manual/.

                                                            The HPR statistics page

                                                            \n

                                                            This is a collection of statistics about HPR, in the form of JSON\ndata. We will use this as a moderately detailed example in this\nepisode.

                                                            \n

                                                            A link to this page may be found on the HPR Calendar page\nclose to the foot of the page under the heading Workflow.\nThe link to the JSON statistics is https://hub.hackerpublicradio.org/stats.json.

                                                            \n

                                                            If you click on this you should see the JSON data formatted for you\nby your browser. Different browsers represent this in different\nways.

                                                            \n

                                                            You can also collect and display this data from the command line,\nusing jq of course:

                                                            \n
                                                            $ curl -s https://hub.hackerpublicradio.org/stats.json | jq '.' | nl -w3 -s'  '\n  1  {\n  2    "stats_generated": 1712785509,\n  3    "age": {\n  4      "start": "2005-09-19T00:00:00Z",\n  5      "rename": "2007-12-31T00:00:00Z",\n  6      "since_start": {\n  7        "total_seconds": 585697507,\n  8        "years": 18,\n  9        "months": 6,\n 10        "days": 28\n 11      },\n 12      "since_rename": {\n 13        "total_seconds": 513726307,\n 14        "years": 16,\n 15        "months": 3,\n 16        "days": 15\n 17      }\n 18    },\n 19    "shows": {\n 20      "total": 4626,\n 21      "twat": 300,\n 22      "hpr": 4326,\n 23      "duration": 7462050,\n 24      "human_duration": "0 Years, 2 months, 27 days, 8 hours, 47 minutes and 30 seconds"\n 25    },\n 26    "hosts": 356,\n 27    "slot": {\n 28      "next_free": 8,\n 29      "no_media": 0\n 30    },\n 31    "workflow": {\n 32      "UPLOADED_TO_IA": "2",\n 33      "RESERVE_SHOW_SUBMITTED": "27"\n 34    },\n 35    "queue": {\n 36      "number_future_hosts": 7,\n 37      "number_future_shows": 28,\n 38      "unprocessed_comments": 0,\n 39      "submitted_shows": 0,\n 40      "shows_in_workflow": 15,\n 41      "reserve": 27\n 42    }\n 43  }
                                                            \n

                                                            The curl utility is useful for collecting information\nfrom links like this. I have used the -s option to ensure\nit does not show information about the download process, since it does\nthis by default. The output is piped to jq which displays\nthe data in a “pretty printed” form by default, as you see. In this case\nI have given jq a minimal filter which causes what it\nreceives to be printed. The filter is simply '.'. I have\npiped the formatted JSON through the nl command to get line\nnumbers for reference.

                                                            \n

                                                            The JSON shown here consists of nested JSON objects. The\nfirst opening brace and the last at line 43 define the whole thing as a\nsingle object.

                                                            \n

                                                            Briefly, the object contains the following:

                                                            We will look at ways to summarise and reformat such output in a later\nepisode.

                                                            I have been struggling with my body weight since I was 35, and I’m\nnow 60.
                                                            \nI know that not all listeners are familiar with the kilogram as unit of\nmeasurement, but we can use the BMI (Body Mass Index) formula to discuss\nthis. It should be somewhere between 22 and 25 and mine has been 33 for\na long time. A very long time. No matter what I tried.

                                                            \nYes, they talk about changing your life style but any change that is too\ndrastic is bound to fail in the end.

                                                            Not another diet hype. That is an industry on its own.
                                                            \nThis is scientific stuff. With lots of links to research papers.
                                                            \nWith large groups and thoroughly peer reviewed.

                                                            \nThere exist other medical reasons why people gain weight.
                                                            \nBut, assuming most people start out in life being healthy, then most\npeople gaining weight are not ill.
                                                            \nSo, if you gain weight, consult your doctor first to rule out any\nmedical reasons.

                                                            So what if insulin is the culprit for gaining weight?
                                                            \nInsulin is a hormone. Its job is to send signals through the body.
                                                            \nIts use is to allow body cells to absorb nutrients in the blood\nstream.

                                                            \n

                                                            Every time you eat the insulin peaks and subsides normally three\ntimes a day.

                                                            \n

                                                            Body process called gluconeogenesis. Making fat in the liver for one\nday storage.

                                                            \n

                                                            If you eat the body makes insulin. That is normal.
                                                            \nIf you eat more, the body makes more insulin.
                                                            \nBody cells adjust to the higher level and become tone deaf to insulin:\nInsulin resistant.
                                                            \nThis means next time the insulin level needs to be higher.
                                                            \nAnd higher levels of insulin mean you will gain weight.

                                                            \n

                                                            If you eat sugar, it is so easy to break down that it goes\nimmediately into storage, e.g. body fat.

                                                            \n

                                                            The thing is, wheat is chemically a long string of sugars. So the\nbody will break it down into sugar and send that too to storage.

                                                            \n

                                                            And almost any food we buy these days contains sugar.
                                                            \nExcept unprocessed foods like vegetables.

                                                            \n

                                                            How to lose weight? Well, the body needs to access the fat in\nstorage. So we need to extend not eating until the liver has run dry of\nthe daily dose of liver fat.

                                                            \n

                                                            This is very easy. Just extend the daily period that you do not\neat.
                                                            \nWhen do you not eat? When you sleep. So, skip breakfast. The name says\nit all, you are breaking your fast.

                                                            \n

                                                            Drink some coffee (no sugar of course), or tea, or water and try to\nstart eating later in the day.

                                                            \n

                                                            And another word for not eating is fasting. But it is a voluntary\nfast!

                                                            \n

                                                            So I tried this for one day. Skip breakfast and try to eat it at\nnoon. I mean, what could possibly go wrong, right? The next day I had\nlost some weight. And it was sooo easy! I could say 300 grams but again,\nyour mileage may vary or you have no clue what one gram is, let alone\n300. But that is not the point. The point is that I lost weight! And to\nme this has been super easy.

                                                            \n

                                                            So the solution turns out to be:

                                                            \n
                                                              \n
                                                            • extend the time your insulin levels are low. 16, 24 or 36\nhours.
                                                              • \n
                                                            • eat as little sugar as possible.

                                                            \n

                                                            Which brings me to food categories.

And when cortisol rises,\nso too does the insulin levels in your body. So, this simply means that\nstress will lead to weight gain.

                                                            I will talk about information feeds from web sites delivered to my\ncomputer device. I use the term feeds and by that I mean both RSS feeds\nand Atom feeds, the two feed protocols which are very similar.

                                                            \n

                                                            I believe it is very likely you as listener to Hacker Public Radio\nknow about feeds. Not unlikely you even know the technical details far\nbetter than I do.

                                                            \n

                                                            Nowadays many of us use feeds very often without thinking of them as\nfeeds, when we subscribe to podcasts.

                                                            \n

                                                            But feeds have been around for many years. Back in the days, I used\nfeeds for websites I was interested in. But somehow I forgot about it\nand web browsers stopped to support feed subscriptions.

                                                            \n

                                                            A year or two ago I started my new journey into feeds. Although it is\nnot so much talk about feeds nowadays, very many web sites have support\nfor feed subscriptions.

                                                            \n

                                                            To start, at my own personal web site (https://www.hemrin.com/)\nmany of the pages have feeds, typically those that are blog-like pages,\nand you can subscribe to several feeds on my site.

                                                            \n

                                                            From Hacker Public Radio I subscribe to a feed for all show comments.\nSo when you write a comment regarding my show today, I will get notified\nin my feed manager.

                                                            \n

                                                            I primarily use Thunderbird to manage my feeds. I do not need my\nfeeds to be synced to other devices. I use Thunderbird daily for e-mails\nand it is therefore very practical and natural for me to use it also for\nfeeds. In addition I use the Feeder app on my Android-based phone for\nsome feeds.

                                                            \n

                                                            I do not use feeds for web sites I anyway will visit often or that\nhave a lot of news. I would be overwhelmed of feeds. Instead I use feeds\nfor web sites which are not updated so frequently but are sites I want\nto keep an eye on. But some are updated daily, like from the\nparliament.

                                                            \n

                                                            In some cases, feeds are an alternative to subscribe to e-mail\nnotifications and e-mail newsletters.

                                                            \n

                                                            The beauty with feeds is that I am in charge and without giving out\ne-mail or anything - the site owner do not know I subscribe.\nSubscription starts so simple as I type the feed-url into my Thunderbird\nfeed manager. And when I want to end a subscription, I simply delete\nit.

                                                            \n

                                                            Furthermore I subscribe to Status pages. I get notifications for\nexample from my internet service provider for their planned and\nunplanned maintenance.

                                                            \n

                                                            Several authorities have interesting feeds.

                                                            \n

                                                            I have feeds from some companies and organizations.

                                                            \n

                                                            I have feeds from many software developers, for example Thunderbird\nand Linux Mint.

                                                            \n

                                                            I have feeds from some journalists and politicians and alike.

                                                            \n

                                                            I have feeds from persons with competence in various areas I am\ninterested in. And other persons who are interesting for the persons\nthey are and their thoughts.

                                                            \n

                                                            So, this show is to tell you that I have rediscovered feeds and found\nthem useful for me. Maybe you already use feeds. Maybe this show will\ninspire you to have a look into feeds as a useful tool for your personal\nor professional life.

                                                            Overview

                                                            \n

                                                            In the last\nepisode we looked at how JSON data is structured and saw how\njq could be used to format and print this type of data.

                                                            \n

                                                            In this episode we'll visit a few of the options to the\njq command and then start on the filters written in the\njq language.

                                                            \n

                                                            Options used by jq

                                                            \n

                                                            In general the jq command is invoked thus:

                                                            \n
                                                            jq [options...] filter [files...]
                                                            \n

                                                            It can be given data in files or sent to it via the STDIN (standard\nin) channel. We saw data being sent this way in the last episode, having\nbeen downloaded by curl.

                                                            \n

                                                            There are many options to the command, and these are listed in the\nmanual page and in the online manual. We will\nlook at a few of them here:

                                                            \n
                                                            \n
                                                            --help or -h
                                                            \n
                                                            \n

                                                            Output the jq help and exit with zero.

                                                            \n
                                                            \n
                                                            -f filename or\n--from-file filename
                                                            \n
                                                            \n

                                                            Read filter from the file rather than from a command line, like awk´s\n-f option. You can also use ´#´ to make comments in the file.

                                                            \n
                                                            \n
                                                            --compact-output or -c
                                                            \n
                                                            \n

                                                            By default, jq pretty-prints JSON output. Using this\noption will result in more compact output by instead putting each JSON\nobject on a single line.

                                                            \n
                                                            \n
                                                            --color-output or -C and\n--monochrome-output or -M
                                                            \n
                                                            \n

                                                            By default, jq outputs colored JSON if writing to a\nterminal. You can force it to produce color even if writing to a pipe or\na file using -C, and disable color with\n-M.

                                                            \n
                                                            \n
                                                            --tab
                                                            \n
                                                            \n

                                                            Use a tab for each indentation level instead of two spaces.

                                                            \n
                                                            \n
                                                            --indent n
                                                            \n
                                                            \n

                                                            Use the given number of spaces (no more than 7) for indentation.

                                                            \n
                                                            \n
                                                            \n

                                                            Notes

                                                            \n
                                                              \n

                                                            • The -C option is useful when printing output to the\nless command with the colours that jq normally\ngenerates. Use this:

                                                              \n
                                                              jq -C '.' file.json | less -R
                                                              \n

                                                              The -R option to less allows colour escape sequences to\npass through.

                                                              \n
                                                              $ jq -C '.' file.json > formatted.json
                                                              \n

                                                              This is why jq normally only generates coloured output\nwhen writing to the terminal.

                                                            As we saw in the last episode JSON can contain arrays and objects.\nArrays are enclosed in square brackets and their elements can be any of\nthe data types we saw last time. So, arrays of arrays, arrays of\nobjects, and arrays of both of these are all possible.

                                                            \n

                                                            Objects contain collections of keyed items where the keys are strings\nof various types and the values they are associated with can be any of\nthe data types.

                                                            This more complex object was generated by the Random User Generator\nAPI. It is a subset of what can be obtained from this site.

                                                            This one comes from the file countries.json from the Github project\nmledoze/countries. It is a subset of the entry for\nMexico.

                                                            Identity filter

                                                            \n

                                                            This is the simplest filter which we already encountered in episode\n1: '.'. It takes its input and produces the same value as\noutput. Since the default action is to pretty-print the output it\nformats the data:

                                                            \n
                                                            $ echo '["Hacker","Public","Radio"]' | jq .\n[\n  "Hacker",\n  "Public",\n  "Radio"\n]
                                                            \n

                                                            Notice that the filter is not enclosed in quotes in this example.\nThis is usually fine for the simplest filters which don't contain any\ncharacters which are of significance to the shell. It's probably a good\nidea to always use (single) quotes however.

                                                            \n

                                                            There may be considerations regarding how jq handles\nnumbers. Consult the jq\ndocumentation for details.

                                                            \n

                                                            Object Identifier-Index\nfilter

                                                            \n

                                                            This form of filter refers to object keys. A particular key is\nusually referenced with a full-stop followed by the name of the key.

                                                            \n

                                                            In the HPR statistics data there is a top-level key \"hosts\" which\nrefers to the number of currently registered hosts. This can be obtained\nthus (assuming the JSON is in the file stats.json):

                                                            \n
                                                            $ jq '.hosts' stats.json\n357
                                                            \n

                                                            The statistics file contains a key 'stats_generated'\nwhich marks a Unix time value (seconds since the Unix Epoch 1970-01-01).\nThis can be decoded on the command line like this:

                                                            \n
                                                            $ date -d "@$(jq '.stats_generated' stats.json)" +'%F %T'\n2024-04-18 15:30:07
                                                            \n

                                                            Here the '-d' option to date provides the\ndate to print, and if it begins with a '@' character it's\ninterpreted as seconds since the Epoch. Note that the result is in my\nlocal time zone which is currently UTC + 0100 (aka BST).

                                                            \n

                                                            Using object keys in this way only works if the keys contain only\nASCII characters and underscores and don't start with a digit. To use\nother characters it's necessary to enclose the key in double quotes or\nsquare brackets and double quotes. So, assuming the key we used earlier\nhad been altered to 'stats-generated' we could use either\nof these expressions:

                                                            \n
                                                            ."stats-generated"\n.["stats-generated"]
                                                            \n

                                                            Of course, the .[<string>] form is valid in all\ncontexts. Here <string> represents a JSON string in\ndouble quotes. The jq documentation refers to this as an\nObject Index.

                                                            \n

                                                            What if you want the next_free value discussed in the\nlast episode (number of shows until the next free slot)? Just typing the\nfollowing will not work:

                                                            \n
                                                            $ jq '.next_free' stats.json\nnull
                                                            \n

                                                            This is showing that there is no key next_free at the\ntop level of the object, the key we want is in the object with the key\nslot.

                                                            \n

                                                            If you request the slot key this will happen:

                                                            \n
                                                            $ jq '.slot' stats.json\n{\n  "next_free": 8,\n  "no_media": 0\n}
                                                            \n

                                                            Here an object has been returned, but we actually want the value\nwithin it, as we know.

                                                            \n

                                                            This is where we can chain filters like this:

                                                            \n
                                                            $ jq '.slot | .next_free' stats.json\n8
                                                            \n

                                                            The pipe symbol causes the result of the first filter to be\npassed to the second filter. Note that the pipe here is not the same as\nthe Unix pipe, although it looks the same

                                                            \n

                                                            There is a shorthand way of doing this \"chaining\":

                                                            \n
                                                            $ jq '.slot.next_free' stats.json\n8
                                                            \n

                                                            This is a bit like a file system path, and makes the extraction of\ndesired data easier to visualise and therefore quite straightforward, I\nthink.

                                                            \n

                                                            Array index filter

                                                            \n

                                                            We have seen the object index filter .[<string>]\nwhere <string> represents a key in the object we are\nworking with.

                                                            \n

                                                            It makes sense for array indexing to be\n.[<number>] where <number>\nrepresents an integer starting at zero, or a negative integer. The\nmeaning of the negative number is to count backwards from the last\nelement of the array (which is -1).

                                                            \n

                                                            So, some examples might be:

                                                            \n
                                                            $ echo '["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]' | jq '.[1]'\n"Monday"\n\n$ echo '["Sun","Mon","Tue","Wed","Thu","Fri","Sat"]' | jq '.[-1]'\n"Sat"\n\n$ echo '[1, 2, 3, [4, 5, 6]]' | jq '.[-1]'\n[\n  4,\n  5,\n  6\n]
                                                            \n

                                                            We will look at more of the basic filters in the next episode.

                                                            I was inspired by Knightwise's\nepisode\n4109 on future-proofing HPR.
                                                            \nI agree with many of your criticisms, but I'm not sure that a marketing\nstrategy is the best way forward. Many of the most successful and\nsustainable businesses and organizations have been built on\nword-of-mouth.
                                                            \nFor example I heard of Google, Zoom, Gmail, Facebook, Slack, Twitter,\nDiscord, etc from my IRL friends and coworkers rather than from a\nmarketing message. And most of the open source communities I'm a part of\n(Linux, Python, Firefox, Hugging Face, etc) are successful precisely\nbecause their success is not subject to a BigTech algorithm or\nexploitative terms-and-conditions.
                                                            \nMost open source projects are able to build community much by actively\nresisting the temptation to create a marketing message or social media\ncampaign and instead focusing on the authenticity and quality of their\n\"product\" and catering to their contributors' and users niche needs and\nsensibilities.

                                                            All right. Well, good evening, hackers. My name is Clinton. And this\nis a very off the cuff episode for me just to announce that I've got a\nnew microphone. So I just wanted to run through a couple of details of\nthat. Make a show, say a little about the microphone while I got it.\nWhat I hope to do with it. So this is a roadie wireless go to setup. It\ncomes with three little boxes. Roughly, roughly, you can fit each one of\nthe little boxes inside a matchbox. So there are three of these that\ncome with the set that I bought. Two of them are microphones that you\nclip onto your lapel. The third is a transceiver. So at the moment, I've\ngot the transceiver on and I've got one of the microphones on. I bought\nthis because I'm going to be going to a conference soon. And one of the\nthings that I do try to do at conferences is to interviews with people.\nAnd this is kind of nice in that I can switch these two microphones on.\nGive one to myself. Give one to the person I'm interviewing. And I don't\nhave to use a single microphone and shove it underneath their faces. And\nI don't have to swap the microphone between the two of us. The other\nfeature, like the particular reason I've got this model is that each of\nthe two microphone units actually has built in RAM. So it will actually\nrecord, like if you've got it set up in the mode, which I do, you can\nget each microphone to do a backup recording of your presentation. The\nregular mode for this set of microphones is to actually treat the\ntransceiver as a source and plug it into computer or plug it into your\ncamera as a external microphone. But it has this lovely mode, which I'm\nrecording this particular episode to. We can just turn it on. It's not\nthe transceiver is not plugged into a computer. It's not plugged into\nanything. And it'll record something like 40 hours of voice. And later\non, I can hook it up to my computer as a standard mass storage device\nand just download the waveform I believe. So it does have some Windows\nfirmware or Mac firmware. I didn't have too much fun getting that to\nwork under Linux. I tried under a couple of different VM products and\nwasn't having any luck. So try it under wine. I tried under open box.\nEventually I did end up installing like a full Windows 10 install onto a\nqemu image. And that had enough stuff working such that I could install\nthe Rode firmware on it. That let me do an upgrade of the firmware on\nthe two microphones and the transceiver because the first thing you do\nwhen you buy something these days is out of the box you have to upgrade\nthe firmware because why would they do that at the factory before they\nsend it out when they can just make the users do that. And there is a\nphone app but it does not let you update the firmware on these\nparticular hardware models. If I remember the error message correctly it\ndoes look like the Android app lets you update the firmware on other\nRode microphone devices but not this particular model. So I had to go\ndown the track of setting up a qemu. I did find a good blog post on how\nto set up a Windows box on qemu. It had a few things that seem outdated\nso maybe it's a job for future me to write an updated blog post on how\nto do this. If for nothing else instructions on how to do this in future\nwhen I need to rerun the firmware update. The other thing that I really\nneeded to use the software for though is to switch on the recording\noption. So out of the box these things do not record to the memory\nthat's built into the microphones. So I had to get, I had to update the\nfirmware and then I had to run the software on both of the microphones\nto switch on the recording option. But now that that switched on I can\njust hook it up as a USB master device as I've mentioned before and\npresumably I can just copy the files and delete the files and I won't\nactually have to run that software. So yeah there's a number of options\ngoing forward so I can write that blog post with the updated details.\nThere were a number of hoops that I found that I did not have to go\nthrough of the blog post I found so things are getting easier over time.\nDepending on how in depth I want to go I could potentially one day sit\ndown and install like a USB listening device and see if I can work out\nhow to work out if there are any magic packets getting sent to do the\nconfiguration on the device. Do I need to break any crypto stuff or is\nit just a straight command like plug in the device and send a command\nwith a few funky options. So maybe in the very distant future when I've\ngot no other things on I could try and work out a pure USB non windows\nsolution for setting some of these configuration options. I'm not sure\nI'd go down the track of updating the family I think that's probably a\nlittle bit too risky but you know maybe one day in the future. But yeah\nbasically this set of microphones assuming that it works out okay\nassuming that it sounds good. I'll hopefully be using these for\nconferences coming up. Hopefully as well I'll be able to use it for\ncamping and stuff like that so if I'm out and about I'll just be able to\npull out these two things transceiver, microphone, a couple of clicks\nturn them on they talk to each other wirelessly and then start recording\nsomething. So it's much smaller than the current microphone that I'm\nusing so it's much easier to travel with. There are two of them so that\nwhen I'm interviewing someone it's much easier and it's got recording\nmemory so I don't actually have to plug them into a computer so all up\nit should be much easier to use. I think it might even give better\nrecording outputs and hopefully like increase the number of talks and\npresentations that I give on HBO. So that's been Clinton this has been a\nvery off the cuff recording I very much am used to sitting down and\nwriting out a full script for these things so I'm doing this because\nit's cool new hardware but also because HPR needs more episodes. So yeah\nmaybe other people can do an episode on what particular funky wireless\nor what particular microphones that they've got that they enjoy using\nand what the advantages are and disadvantages are. That's it for now.\nCiao.

                                                            Today we will be installing Home Assistant Operating System (HAOS),\non a x86-64 machine.

                                                            \n
                                                            \n

                                                            Home Assistant can be repurposed and installed on various hardware,\nsuch as an Odroid or a generic x86-64 machine. The Home Assistant\nOperating System allows you to install Home Assistant on these devices\neven if you have little to no Linux experience.

                                                            \n
                                                            \n

                                                            We are going to my HP t610 Flexible Thin Client, which has a 16GB\nSATA Flash Drive, and I upgraded it to 16G of Ram.

                                                            \n

                                                            Note that this will install Home Assistant Operating\nSystem (HAOS) as a computer appliance. That means that it will run a\nbare OS with the various components in a customised docker setup. It\nwill take over the entire computer, and requires secure boot to be\ndisabled.

                                                            \n

                                                            On the HP t610 Flexible Thin Client, that involves pressing \"Esc\" at\nboot to get to the bootup menu. If that doesn't work try pressing \"F10\"\njust after turning on the power.

                                                            \n

                                                            Two methods to install

                                                            \n

                                                            HAOS has no integrated installer like you would expect with\ndistro\nhopping, but it requires that the image be burned directly onto the\ndisk of the computer itself.

                                                            \n

                                                            It has two methods to do this and \"Method 2: Installing HAOS directly\nfrom a boot medium\", is basically take the disk out of the target system\nand attach it to your own computer. The use a burning tool like Balena\nEtcher, or dd to write the image to disk. Much as you would\nburn a sdcard for a raspberry pi. I don't have a way to do this so let's\ngo with method 1.

                                                            \nMethod\n1: Installing HAOS via Ubuntu booting from a USB flash drive\n

                                                            Here you download and burn live operating system as you would if you\nwere\ndistro\nhopping, the document suggests to use Ubuntu. I tried it but my HP\nt610 Flexible Thin Client didn't like it. It also didn't like Fedora\ndespite having worked earlier, so I just used\nDebian\nLXQT.

                                                            \n\n

                                                            Now you have Debian running off a usb stick on your target\nmachine.

                                                            \nSteps\nto burn Home Assistant Operating System (HAOS) to disk on target\n

                                                            Anything after the '#' character is a comment and doesn't need to be\ntyped.

                                                            \n

                                                            Note The following steps are optional, and you\nshould only do them if you wish to ssh to the target machine from your\npc.

                                                            \n
                                                            # Anything after the '#' charachter is a comment and doesn't need to be typed.\napt install openssh-server  # Install the ssh server on the target\nsystemctl start ssh         # Start it once installed\npasswd user                 # Change the password or you can just use the default which is `live`\nip add                      # Get the IP address of the target\nssh user@ip.of.the.computer # Replace ip.of.the.computer with the actual ip address in the step above
                                                            \n

                                                            Open a terminal on the machine, and type the su -\ncommands to get root access on the Debian OS running from the usb drive\non the target machine.

                                                            \n
                                                            user@debian:~$ su -\nPassword:\nroot@debian:~#
                                                            \n

                                                            Now you are root, the super user admin, you can install the\nwget command using the Debian apt package\nmanager.

                                                            \n
                                                            root@debian:~# apt install wget
                                                            \n

                                                            Once wget is installed, we can use it to download the latest image\nfrom the\nHAOS\nDownload Page, which is haos_generic-x86-64-12.1.img.xz\nat time of writing.

                                                            \n
                                                            root@debian:~# wget https://github.com/home-assistant/operating-system/releases/download/12.1/haos_generic-x86-64-12.1.img.xz
                                                            \n

                                                            Now we have the image we are going to write to the disk, but the\nquestion is which disk to write it to.

                                                            \n

                                                            Your target PC will be different to mine but the tool\nlsblk is good for showing what is installed and\nmounted.

                                                            The loop0 is the mount where Debian is running from,\nwhile the mounted sdb1 and sdb2 have the word\nlive telling us that's the actual USB drive we installed Debian\non to.

                                                            \n

                                                            While your disk will be different, for me the disk to install it on\nis sda. The partitions sda1,\nsda2, and sda3 are left overs from a previous\ninstall. They will be overwritten anyway.

                                                            \n

                                                            The drive I will be targeting is therefore known to the system as\n/dev/sda

                                                            The dd command will do a disk duplication and writes the\nones and zeros from the if input file, to the\nof output file.

                                                            \n

                                                            The command below will take a while and not display anything

                                                            I don't know much of anything. I'm a Linux user, about the same way\nmost people are Windows users. I have gotten more technical over the\npast few years largely due to being a regular on various Linux podcasts.\nI don't have sufficient education to be hired in computers (although\nI've tried several times), and I did spend a few years in radio back in\nmy youth.

                                                            \n

                                                            So what do you have to know to become a podcaster? Almost nothing.\nJust so long as you have a computer, an Internet connection, and a\nmicrophone. (For some shows, you may need a webcam.)

                                                            \n

                                                            I got into podcasting by asking questions. I tried for almost 2 years\nto get Chris Fisher at Jupiter Broadcasting to co-feature me, with zero\nexperience, on a podcast about using Linux desktops. It never happened.\nSo when in 2018 Rob Hawkins asked for new hosts to take over mintCast, I\nwas one of the first 10 or so people to apply, and one of 6 who\neventually stuck with it. All I had was a computer, an Internet\nconnection, and a Blue Yeti microphone my little sister gave me. Within\na few months, I started another podcast, Distrohoppers' Digest with Tony\nHughes. And a couple years later, I was asked to take over Full Circle\nWeekly News. Apparently some people like my voice. Since starting my\nlittle mini-career in podcasting, I have probably more than doubled what\nI know about Linux. I'm not all that scared of the Terminal\nanymore...

                                                            \n

                                                            Some microphones are pretty bad, and my Blue Yeti was the worst one\non the show when I joined mintCast. In about a year, I found a very\ninexpensive CAD Audio U29 USB mic, currently $20 at Amazon, and that\nworked pretty well. Some time after taking on Full Circle Weekly News,\nthe magazine bought me a Samson Q2U ($60), which I'm still using. I love\nthis mic, as it can be used either as a USB mic or plugged into a sound\nbox for even better audio.

                                                            \n

                                                            When I started, I had a T430 laptop and the Blue Yeti microphone. My\nlisteners and co-hosts have made my life better with new and used\nequipment I could never have afforded on my own, including laptops,\nRaspberry Pis, modems, routers, headphones, and even a sound box. My\ncurrent setup includes a 2016 Lenovo ThinkCentre M600 Tiny, which cost\nme under $200 on eBay, a Focusrite Solo sound box (a gift from a\nfriend), a WavLink ST336A external goodies box (also a gift), and an old\nDynex 26\" TV I use as a monitor I paid $15 for locally. I have a boom\narm for my microphone, which is made by Neewer and costs $15 on Amazon.\nMy keyboard is a Fellowes Microban Natural, which I need as a trained\ntouch typist. And I put all this stuff on a little rolling computer\ndesk, which I bought used locally for $25.

                                                            \n

                                                            The only software I use is Audacity, and I didn't need to know any\nmore than the basics. If you're part of a team, such as mintCast, you\naren't even required to do any audio editing, although if you know your\nway around Audacity you will find your skills very welcome.

                                                            \n

                                                            If you want to start podcasting, have the equipment, contact Ken\n(Note: I misspoke in the audio and said Ronnie where I\nmeant Ken) and do something here at HPR, which is a fairly low\nentry bar, or you might contact long-running shows such as mintCast.\nParticipation and commitment are usually all that is required.

                                                            \n

                                                            OK, so maybe you want to do more than produce an HPR show or join\nmintCast. You have your own idea and you want to get it out there, your\nown personal podcast. This is where it gets a little more detailed. If\nyou already have the information you need, you can stop the podcast\nhere, but...

                                                            \n

                                                            First, you'll need a website or blog (if you're really broke, there\nare free WordPress sites available at wordpress.com, or you could use\nthe dreaded Google blogs (blogger and blogspot). Other than that, you'd\nhave to register a domain name, find a webhost, and write a website,\nsome of which can be cheap (or not!). Then you have to find a way to\nstream your podcast. Google has closed Feedburner, but there are some\npaid places like Red Circle you can get for not much bread. Those will\nprobably help you stream your podcast to places like Apple Music,\nArchive.org, Spotify, etc. But if you want help from me, I'm already\nlost. mintCast is handled by Bill H., Distrohoppers' Digest is handled\nby Dale M., and my Full Circle Weekly News is uploaded to Ronnie for\npublication.

                                                            \n

                                                            Or maybe you want to do it with a few friends, and they can't cram\nthemselves into your bedroom to do that. In that case, you should\nexplore using Discord, Jitsi, VDO.ninja, or (sizzle preserve us!) Zoom.\nEveryone will need to record their own part of the stream, and you'll\nneed someone who knows Audacity well enough to edit a few (or several)\nstreams together. Maybe you want to post it on YouTube. If you want both\na video and audio podcast, someone will have to learn OBS and\nAudacity, and if you want the video podcast to be edited, have fun\nlearning one of the many video editors out there (you might start with\nKDEnlive).

                                                            \n

                                                            For more information on streaming, you'll need to get someone else to\nmake an HPR podcast on the subject. Way over my head.

                                                            \n

                                                            I hope this little show has pushed a few of you into wanting to try\nyour hand. It doesn't take much, or it takes a whole lot, depending on\nwhat you want to do, and your future listeners will thank you. My\nlisteners have certainly shown me lots of thanks.

                                                            The reason I found HPR can be traced back to the 1990's when I first\nheard about Linux and I got interested in Linux. But it was not until\nten years ago that I actually started to try Linux for real. A friend\nwas enthusiastic about Linux. Although he did not have a computer\nhimself, he made CD copies of multiple Linux distributions and gave to\nme. And it happened more than once.

                                                            \n

                                                            At this time I was on macOS on a macMini. But I also had a cheap\nlaptop with Windows 10 for a few programs. That laptop was too cheap\nwith too little memory and soon, despite it was not old, it could not\nmanage to keep Windows updated, it had too little memory even without\nadditional software: 32 GB hard drive and 2 GB RAM. So, this was the\ndriver to install Linux for real. I installed Linux Mint. And the laptop\nwas now usable again, with an updated operating system.

                                                            \n

                                                            My interest in Linux Mint led me to start listen to the pod Mintcast\nsome years ago.

                                                            \n

                                                            One of the hosts of Mintcast was also an HPR correspondent, and in\nhis presentation of himself at every pod episode he told he gave shows\nat HPR and shared his ID number.

                                                            \n

                                                            Every Mintcast pod episode also had acknowledgements where Mintcast\nthanked HPR for letting them use the HPR Mumble server.

                                                            \n

                                                            At the end of each year, Mintcast also sends the jingle for the HPR\nNew year show where everyone is welcome to live chat or just listen.

                                                            \n

                                                            I know I have tuned in and listened to the New year show. Eventually\nI also listened to one or another show in earlier years.

                                                            \n

                                                            When Mintcast this year, 2024, has talked about Hacker Public Radio\nthey have mentioned it was low on episodes and encouraged Mintcast\nlisteners to contribute.

                                                            \n

                                                            It was after this I finally started to become a regular listener to\nHacker Public Radio and at the same time recorded my first show.

                                                            \n

                                                            I like HPR for its community based host approach.
                                                            \nI like that shows mostly have the Creative Commons\nAttribution-ShareAlike 4.0 International (CC BY-SA 4.0) license.
                                                            \nI like the concept of knowledge and experience sharing.
                                                            \nI like that the content is what matters most, the equipment and\npresentation skills are of less importance.
                                                            \nI like the monthly community shows with feedback and review of shows and\ncomments.
                                                            \nI like the occasional comments to my shows and my possibility to comment\nother shows on the website.

Obviously, we normally take great care that incoming shows\nare unlikely to trigger such problems in the first place.

                                                            • There is a feed which is normally referred to as the \"Future Feed\",\nwhich can be found on the RSS Syndication\npage. It receives shows which are posted out of order as they come\nin and may be replaced/reposted if errors are found. This is intended as\na means to find issues with metadata or the audio quality of new shows\nbefore they hit the main feed.

                                                            We live in a time where everything is streamed; from our TV, radio,\npodcasts everything is fine until the internet goes down. Gone are the\ndays of simply turning on the TV with a set top aerial. With this in\nmind, I set up an old Raspberry Pi 2 and connected it to use as a video\nand music server through a Samba share.

                                                            \n

                                                            To complete this task you will need:

                                                            \n
                                                              \n
                                                            • A Raspberry Pi
                                                              • \n
                                                            • A micro-SD card
                                                              • \n
                                                            • An Ethernet cable
                                                              • \n
                                                            • An external hard drive (min 2TB recommended)
                                                              • \n
                                                            \n

                                                            Step 1: Update your Pi software in the terminal:

                                                            \n
                                                            sudo apt update && sudo apt upgrade
                                                            \n

                                                            Step 2: To allow us to share our files over a network we will install\nSamba:

                                                            \n
                                                            sudo apt install samba
                                                            \n

                                                            Step 3: To find UUID and the file system of the drive, enter:

                                                            \n
                                                            sudo blkid
                                                            \n

                                                            Ignore the line with fat32, this is your Micro-SD\ncard.

                                                            \n

                                                            Step 4: We need to mount this drive automatically whenever the\nRaspberry Pi is switched on. Firstly, we'll need to create a location to\nmount the external hard drive, we can do this by using the command:

                                                            \n
                                                            sudo mkdir /media/external
                                                            \n

                                                            Step 5: Now we need to edit the fstab to tell the Raspberry Pi to\nautomount the external drive every time it is switched on

                                                            \n
                                                            sudo nano /etc/fstab
                                                            \n

                                                            Insert the following line at the bottom of the page:

                                                            \n
                                                            UUID="{the UUID you noted down in step 3}"     /media/external   {type noted in step 3}     auto,user,rw      0     0
                                                            \n

                                                            The above should all be on one line, pressing the tab key to create a\ngap between each piece of information.

                                                            \n

                                                            Step 6: Now we need to set up which folders are going to be shared.\nI'll assume that we are going to make the whole of the external drive\navailable over the network

                                                            \n
                                                            sudo nano /etc/samba/smb.conf
                                                            \n

                                                            At the bottom of the page add the following, note that you can call\nthis anything you wish, just exchange the word external but you must\ninclude [ ]:

                                                            \n
                                                            [external]\npath = /media/external\navailable= yes\nbrowsable = yes\npublic = yes\nwritable = yes
                                                            \n

                                                            It's worth noting before we continue that I've set the option\nwritable = yes, this means that you can add to or remove\nthe contents of the external drive over the network. If you are not\ncomfortable having this option then simply change it to\nwritable = no. Now save and exit (ctrl + X), make sure that\nyou answer 'yes' to save your changes.

                                                            \n

                                                            Step 7: We will now set the Raspberry Pi to log in automatically on\nstartup, if the user Pi isn't logged in then all of things we've just\nset up will not work. Type:

                                                            \n
                                                            sudo nano /etc/inittab
                                                            \n

                                                            Navigate down to the line:

                                                            \n
                                                            1:2345:respawn:/sbin/getty --noclear 38400 tty1
                                                            \n

                                                            and add --autologin pi after getty to make\nthe line:

                                                            \n
                                                            1:2345:respawn:/sbin/getty --autologin pi --noclear 38400 tty1
                                                            \n

                                                            Save and exit (ctrl + X) make sure that you answer 'yes' to save\nit.

                                                            \n

                                                            Step 8: We can try it out our system and auto-login by using the\ncommand

                                                            \n
                                                            sudo reboot
                                                            \n

                                                            Assuming that everything goes well, your system should be up and\nrunning. Try and find it on a computer through the file manager. I\npersonally recommend saving the Pi location on Kodi for an easy to use\nsolution for browsing your media on a TV.

                                                            In two earlier episodes I have been talking about digiKam photo\nmanagement software. I hope to come back to that topic in another\nepisode in the future. But not today.

                                                            \n

                                                            Today I will talk about what happened to me about two weeks ago.\nMaybe it was because I had used the hibernate state, which I rarely use,\nthat caused my laptop to behave somewhat strange. So I decided to turn\nit off. It was my Lenovo Thinkpad T460p laptop, running Linux Mint\nDebian Edition.

                                                            \n

                                                            So I turned it off the normal way with the soft button inside the\noperating system. But instead of power off I was shown a full terminal\nscreen with a lot of text what it was doing. But it never came to the\nconclusion to turn off.

                                                            \n

                                                            I have learned that in those situations, although tempting, that on\nLinux I should not force turn off with the physical mechanical power\nbutton. I have tried that before on another Linux laptop, and it was not\na success, rather the opposite.

                                                            \n

                                                            What I should do with Linux is to talk with electrodes directly to\nthe central brain, or in other words, call the Linux kernel with help of\na system request and by that sidestep the operating system.

                                                            \n

                                                            A System Request is done with the SysRq key on the keyboard. In this\nsituation I did the reisub key sequence with a system request:

                                                            \n

                                                            If I hold the System Request key together with the Alternate Alt key,\nand when still holding them down, I type the letters r, e, i, s, u and\nb, one by one in a very slow pace, I take seconds between them. Then I\nrelease all keys and the machine reboots.

                                                            \n

                                                            This was very successful for me and the laptop has since then worked\nas normal.

                                                            \n

                                                            I use an external full size keyboard that has a System Request\nkey.

                                                            \n

                                                            But not all laptops has such a key any more. System Request can be\nreached also on all or most of those laptops with some key combination.\nBut that key combination varies between manufacturers and models.

                                                            \n

                                                            In the show notes I add a link to a How to geek article about reisub\nas well as to Wikipedia about System Request:

                                                            It is obvious to most people that we need to stop burning fossil\nfuels to prevent even worse global climate change. Options like solar\npanels and windmills are options for providing clean renewable\nelectricity, but since so much of our fossil fuel use is for\ntransportation, we need to make strides in improving batteries and\ncharging. Fortunately there have been some very positive developments\nthat will show up within just a few years

                                                            I keep hearing people complain that they can't find a decent computer\nunder $2,000. My response is: lower your expectations, and help end\ndigital waste. Do you really need a top-end gaming machine? Most games\nwill run on older computers just fine. And there are LOTS of 2016 models\n(and a few newer years) coming off office leases.

                                                            \n

                                                            My suggestion is the Lenovo ThinkCentre M700 Tiny; I will have other\nsuggestions later in the podcast, but this is what I went with an have\npersonal experience. The M700 Tiny is a box about the size of an older\nexternal DVD drive, with your choice of an i3, i5 or i7 processor, up to\n64 Gb RAM, and a power supply sipping away at up to 35 watts. If you go\non eBay or your local equivalent, you can find these for ridiculously\nlow prices.

                                                            \n

                                                            My recommendation is to go for a box with an i5, 8 or 16 Gb RAM, with\nor without a drive. You can find them even cheaper if you search for \"no\nOS\", which frequently still includes the drive, but SSDs are quite cheap\nthese days so it hardly matters. I recommend the i5 rather than the i7\nbecause, in the 2016 models, the i7 wasn't much more than a heat\nproducer compared to the i5 but no faster, and the i5-based machines are\noften $100-150 cheaper.

                                                            \n

                                                            Of course I recommend putting the Linux of your choice on these\nmachines when you get it.

                                                            \n

                                                            You will need a monitor and keyboard for this. If you don't already\nhave one, I would suggest looking locally for a used 26\" LCD/LED TV. You\nwill also want a cable for it, and you can either get a DisplayPort\ncable while you're at eBay, or a DP-to-HDMI adapter to use the HDMI\ncable which probably comes with the TV. For a keyboard, you should go to\nyour local big box store and get one you like, if you don't want to buy\nused. You can find them from $5 to $20.

                                                            \n

                                                            I apologize for my US-centric prices, but you should have similar\nprices in your local currency if you have eBay or something like it.

                                                            \n

                                                            I just did a quick lookup for \"M700 Tiny No OS\" on eBay, and saw i5\nmachines which were purported to work from between $80 and $120 with 8\nGb RAM. Be careful to watch for shipping prices, I see a particularly\ngood-looking refurbished model with 16 GB for under $120 -- but the\nshipping is over $35 from Australia!

                                                            \n

                                                            If you want an AMD chip, you'll need to research the model number...\nbut they do make them, just not as many.

                                                            \n

                                                            If you don't like Lenovo, you can find Dells and HP EliteDesks in the\nsame range. One good thing about the HPs is that they label which\ngeneration they are -- G2, G3, G4. Newer generations cost more, but will\nbe more future-proof. There is currently an HP EliteDesk 800 G2 with 8\nGb RAM and No OS on eBay for $50! Again, if you buy a G3 or G4 it will\ncost more, but be a newer machine as well.

                                                            \n

                                                            These are all 64-bit quad-core computers, some over 3 GHz, with low\npower demands. Cheap to buy, cheap to use. Any version of Linux will run\non them, and if you're desperate you can run Windows 10 on them as\nwell.

                                                            \n

                                                            That should be enough to get you started. If you have questions,\nwrite me at bardmoss@pm.me.

The seals are mainly on the beach\nand the team runs to intercept the ones they spot with garbage around\nthem. They net them and remove whatever they have picked up and release\nthe seals. In many cases the fishing line, net, or other junk has cut\ndeeply into the seal's skin and muscle, and would kill them if not\nremoved. Episodes are usually daily and mostly short.\n

                                                            \nSo Krita is a digital painting application.

                                                            \nSo we've got a huge number of brush engines, color spaces for people who\nneed to print and lots of features really focused at creating art from\nstart.

                                                            \n

                                                            Pretty much everything. I've seen so many different artworks,\ndifferent styles.

                                                            \nPeople are working with illustrations.
                                                            \nThere are people who design those trade book card with Krita.
                                                            \nGames, I mean, whole animated games, like platform games.
                                                            \nIt's used for all that sort of thing, for everything, in every style, in\npretty much every country in the world.

                                                            \n

                                                            There are so many! We got sent a copy of a book on American wild\nbirds.
                                                            \nThat was entirely done in Krita.

                                                            \nTalk a little bit about yourself. What role did you play in the creation\nof Krita?

                                                            \n

                                                            This year Krita is 25 years old.
                                                            \nWhich meant I wasn't there at the absolute beginning.
                                                            \n

                                                            \n

                                                            So, in 2003, my parents gave me for my birthday a really small\ngraphics tablet, a Wacom Graphire.
                                                            \nAnd I wanted to use it to draw a map for a fantasy novel I was writing\nback then.
                                                            \nThe novel never got finished, because of course I wanted to use Linux as\nmy desktop operating system.
                                                            \nAnd I sort of couldn't get into GIMP, and I started looking around for\nan application other than GIMP that I could maybe improve or could maybe\nbe good enough.
                                                            \n

                                                            \n

                                                            Well, I found Krita.
                                                            \nIn 2003, it had already gone through three names: KImageShop. That\ndidn't last long. Krayon. That didn't last long either. And it was\nfinally called Krita.
                                                            \nIt has also gone through three complete rewrites.
                                                            \nSo when I started working on Krita in 2003, it didn't even have a brush\ntool.
                                                            \nYou could open images, add images as layers, and move the layers\naround.
                                                            \nAnd that was everything.
                                                            \n

                                                            \n

                                                            So, it was a really good place to get started.
                                                            \nExcept, of course, that it turns out that I'm not a genius.
                                                            \nI'm not even a computer scientist.
                                                            \nI mean, I'm a linguist.
                                                            \nAnd writing a good brush engine is pretty difficult.
                                                            \n

                                                            \n

                                                            So, I started blogging about how I was completely failing at creating\na nice brush engine. And how is was failing.
                                                            \nThat turned out to be a turning point for the project because people saw\nthat: \"Oh, there's someone working on it, and they're not making any\nprogress, mmm, I will take a look as well.\" They started getting\nenthusiastic and pretty soon after 2004, we already had our fourth\ncomplete core rewrite.
                                                            \nSo that's how I got started.
                                                            \n

                                                            \n

                                                            So how many people were involved in the Krita community by that\ntime?

                                                            \n

                                                            Mid 2004, it was about a dozen.
                                                            \nKrita was still part of KOffice, which was KDE's suite of productivity\napplications.
                                                            \nAnd KOffice developed that still, because they were porting from one\ndocument format to another document format.
                                                            \n

                                                            \n

                                                            But suddenly there was an application that we really wanted to\nrelease. And that's when KOffice got released again as well.
                                                            \nSo it's a bit hard to say how many people are actually working on Krita\nbecause there were also some people working on the core libraries that\nevery application used, but say a dozen.
                                                            \n

                                                            \n

                                                            And can you speak a little bit about how the community evolved\nsince?

                                                            \n

                                                            Yes. Until around 2006, we didn't really have a focus. Krita was a\nGIMP clone or a Photoshop clone. And, in 2006, David Revoy, a French\nartist who only uses free software, tried Krita, and he told us it's no\ngood. While we thought we had quite a nice application by then.
                                                            \n

                                                            \n

                                                            Afterwards, we started taking this very seriously. So, when we have a\nsprint, we also invite artists.
                                                            \nWe actually videotape the artists working with Krita.
                                                            \nAnd that's for the developers a really nice way of getting to know where\nthe bottlenecks are for users.
                                                            \nSo because we involved artists, our developer community also started to\ngrow.
                                                            \n

                                                            \n

                                                            At some point of time, most growth came through Google Summer of\nCode, but those days are over.
                                                            \nThat program is not doing a lot anymore. We've only got one student this\nyear.
                                                            \nSo that started the second phase. Let's make Krita good enough for David\nRevoy.
                                                            \n

                                                            \n

                                                            We also invited Peter Sicking to a print.
                                                            \nPeter Sicking is the guy who was involved in defining the mission\nstatement for GIMP.
                                                            \nHe sat down with us and asked us: \"What do you really want to do?\" Make\nKrita good for David Revoy.
                                                            \nThat's a bit thin as a mission statement.
                                                            \nSo we came up with we want to make Krita purely a painting\napplication.
                                                            \nSure, there are filters and other stuff, but if it's good for painting,\nit goes in.
                                                            \n

                                                            \n

                                                            So we started working on that and that took quite a long time to get\nthere, especially because we were stupid.
                                                            \nWe started doing a complete rewrite in 2007 of everything.
                                                            \nThat was the fifth.
                                                            \nSo, that continued, everyone was working on Krita as a hobby. Most\npeople were still students, until our Slovak student, Lukáš, was working\non his thesis.
                                                            \nAnd his thesis was brush engines for Krita.
                                                            \nAnd of course he got 10 out of 10 because he could show his professors\nthat he had created real software that was used by real people all over\nthe world.
                                                            \nAnd then he was like, okay, I'm almost done with university.
                                                            \nWhat should I do? If you guys can pay my rent, then I can work on Krita\nfull time.
                                                            \nIf not, I'm going to flip burgers.
                                                            \nSo I ask him what his rent was. It was like 35 euros a month.
                                                            \nSo I thought, well, let's do a fundraiser and we can pay you for, say,\nsix months.
                                                            \nSix months turned into a year.
                                                            \nAnd after that, Lukas got a job at a different company, but it started\nsponsored development.
                                                            \n

                                                            \n

                                                            And that's been really important for the growth of our community,\nbecause by now there are six people working full time on Krita.
                                                            \nThe second student we hired on graduation was Dmitry Kazakov, a Russian\nguy, and he's currently our lead developer.
                                                            \nSo because we're all there, lots of volunteer developers can see that\ntheir patches and merge requests get reviewed, they get merged and that\nmakes people happy.
                                                            \nSo we have a really healthy mix right now of sponsors and volunteer\ndevelopers.
                                                            \n

                                                            \n

                                                            That sounds great. You mentioned sprints a couple of times, can you\ntell us a little bit more about how that is organized?

                                                            \n

                                                            In theory, we organize one big sprint a year.
                                                            \nOf course, it hasn't been possible.
                                                            \nSome people have had to flee Russia, for instance.
                                                            \nSo visa problems are real problems.
                                                            \nAnd the way it mostly used to happen was I would invite everyone to\nDeventer, have some people sleep upstairs, in our spare bedrooms.
                                                            \nAnd the rest would go to Hotel Royale in Deventer, which has two big\nrooms on the top floor.
                                                            \n

                                                            \n

                                                            Then we'd go down in the cellar of the church. It's a 12th century\ncellar. Really roomy, and we would just do some hacking, then do a\nmeeting.
                                                            \nAnd in the evenings, we would go out for dinner, and just get to know\neach other better.
                                                            \nOne thing that I really miss about sprints, or rather not having\nsprints, is the time we would spend in my study over there.
                                                            \nJust, just a couple of us.
                                                            \nThe rest would be hacking around.
                                                            \nAnd we would try to just go through the list of bug reports.
                                                            \nAnd for us, sprints are fun.
                                                            \nWe also invite developers, artists, documentation writers.
                                                            \n

                                                            \n

                                                            Yeah, that sounds like a lot of fun.
                                                            \nSo, if a new contributor would like to join Krita, what would be the\ntypical on ramps that they could come into?

                                                            \n

                                                            It used to be that people would mostly join us on IRC. Nowadays, we\nalso have Matrix, because building Krita from scratch is not easy.
                                                            \nBut we've got a great manual for that by now.
                                                            \nSo either people join us on IRC and ask for help building Krita, and\nthen maybe ask, do you know a nice bug or feature ish that I could start\nworking on?

                                                            \n

                                                            And then we, we'd help them with that.
                                                            \nBut these days it's mostly people who out of the blue, post a merge\nrequest on KDE's GitLab instance.
                                                            \nAnd then we're \"Oh, this person from Serbia, this person from Denmark,\nthey have suddenly have a really nice patch!\" And sometimes a patch\nneeds to be improved.
                                                            \nSometimes it can go in as is.
                                                            \nAnd then we try to get them, in our chat channel, because that's still\nthe place where we have most development discussions.
                                                            \nAnd the mailing list is almost dead, but that holds for many mailing\nlists.
                                                            \nAfter that, once you've got three merge requests in Krita, merged into\nKrita, we will ask you: \"Do you want to have a developer account, so you\ncan review other people's work, merge it, get full access to\neverything?\" And sometimes they are \"Yes, I've always wanted that\", and\nsometimes \"I'm not really comfortable with that, I just want to send you\nmore patches\", and that's fine.
                                                            \n

                                                            \n

                                                            Sounds great.
                                                            \nIn terms of features, are there any particular features of Krita that\nyou're particularly proud of, or that sets Krita apart from other\ndrawing programs?

                                                            \n

                                                            Over the years, we had a number of firsts.
                                                            \nLike, before Adobe even knew that OpenGL existed, we had a hardware\naccelerated canvas implementation.
                                                            \nThen, about the same year, I think it was 2005, we implemented support\nfor all kinds of color models.
                                                            \nLike CMYK, LAB, also painterly color models.
                                                            \nThat's stuff that tries to mix spectral wavelengths to simulate the way\npaint mixes.
                                                            \n

                                                            \n

                                                            That feature is out because it never worked well enough.
                                                            \nThen we got, I think, a really nice way of doing animations.
                                                            \nOf course the brush engines are great.
                                                            \n

                                                            \n

                                                            Oh, and this is something that almost nobody knows, but we support\npainting in HDR.
                                                            \nSo color values lower than zero and bigger than one, fully\ndynamic.
                                                            \n

                                                            \n

                                                            And the way we work with those images is compatible with the way\nBlender imports images.
                                                            \n

                                                            \n

                                                            So, you mentioned Blender, are there any other products that Krita\nworks particularly well with, or that are nice complements to Krita?

                                                            \n

                                                            Scribus. Scribus is a desktop publishing application, it's also free\nsoftware.
                                                            \nDevelopment is a bit slow at the moment, but it's really solid.
                                                            \nWe used it for our 2006, I think it was 2006, Krita art book, for\ninstance.
                                                            \nAnd Inkscape of course, as well.
                                                            \n

                                                            \n

                                                            Krita does have vector layers, and they are quite advanced, but still\nInkscape is a really good complement.
                                                            \nKrita and Inkscape are the only applications that currently implement\nthe W3C mesh gradient standard.
                                                            \n

                                                            \n

                                                            Cool, and in terms of current development, which features are you\nmost excited about which are coming up?

                                                            \n

                                                            What's coming up is the port of Qt6, new version of our development\nlibrary.
                                                            \nThat's going to really eat development time.
                                                            \nBut again, we've got some volunteers who already started working on\nthat.
                                                            \n

                                                            \n

                                                            I'm not sure I'm really excited about it, but, but we have to\ninvestigate it. We are looking into AI assisted inking.
                                                            \nSo you would train Krita on the way you would normally ink your\nsketches.
                                                            \nAnd then Krita should be able to semi-automatically ink your sketches\nfor you.
                                                            \nBecause for many artists inking is a bit of a boring step, because when\nyou're doing inking, you're often really, really careful.
                                                            \nAnd that means that the lines are a bit, often a bit deader compared to\nthe sketch, um, Trying to use AI to assist with that is something we are\ninvestigating.
                                                            \n

                                                            \n

                                                            We are working on that together with Intel because Intel is one of\nour corporate sponsors.
                                                            \nBut we are also doing all kinds of projects with Intel. Like, Intel also\nworked with us on that HDR feature, for instance.
                                                            \n

                                                            \n

                                                            Oh, and text. That's, that's important as well. Volterra has been\nworking on that.
                                                            \nThe text shape and the text tool, like the object that contains text on\ncanvas and the tool that modifies it are of course two different\nprojects.
                                                            \nThis will implement full SVG to text including CSS, ligatures, font\nfeatures and everything.
                                                            \nAnd she's already implemented it.
                                                            \nAnd the text shape itself, it can do vertical text, like for Chinese or\nJapanese.
                                                            \n

                                                            \n

                                                            It can do Ruby, which is the furigana, the small, text that in\nJapanese you put next to the kanji, the Chinese derived characters, so\nyou know how to pronounce them.
                                                            \nAnd she's now working on the UI, and, and it's something we've wanted to\nstart working on, uh, years ago already, I think it was 2017.
                                                            \n

                                                            \n

                                                            Actually, I was working on that, but then I was distracted by the\nDutch tax office which wanted to have money.
                                                            \nAnd I had to do difficult stuff and hire accountants and so on.
                                                            \nAnd it's not easy being a manager.
                                                            \n

                                                            \n

                                                            So that's the two big things that are coming, hopefully: The\nexperimental assisted inking an a super deluxe text tool.
                                                            \n

                                                            \n

                                                            Cool.
                                                            \nSo what does your release schedule look like? Do you have set dates or\nis it ready when it's ready?

                                                            \n

                                                            Ready when it's ready, but it's often ready.
                                                            \nIf our infrastructure is working correctly, then we typically do a\nbugfix release every two months.
                                                            \n

                                                            \n

                                                            There have been years when we did one every month, but that was just\neating up too much of our time. We try to have one or two full feature\nreleases a year as well.
                                                            \nOf course, we moved from Jenkins as our binary factory platform to\nGitLab CI.
                                                            \nAnd that means we haven't been able to do a release for six months\nbecause so many bits needed fixing, bits were broken.
                                                            \nThe whole pipeline had to be rewritten.
                                                            \nBut that's done now.
                                                            \nSo we just released 5.2.3 beta 1. And we hope to do the 5.3 pretty soon,\nwhich is a bug fix release.
                                                            \nAnd 5.3 will be a feature release again.
                                                            \nI think we've got almost enough features in there. We're only waiting\nfor the text tool to be completed.
                                                            \n

                                                            \n

                                                            That sounds great.
                                                            \nIn terms of, uh, volunteers, are there any areas that you would really\nappreciate someone helping out and looking into things?

                                                            \n

                                                            Android experts, because our Android expert started at a very\ndifficult university and doesn't have any spare time anymore.
                                                            \nAnd Android is, is a difficult platform.
                                                            \nPlatform itself, the libraries, it changes all the time.
                                                            \n

                                                            \n

                                                            We do have a UX designer, Scott Petrovic, but more help there would\nalso be welcome.
                                                            \n

                                                            \n

                                                            And for the rest, it's actually mostly not what we wish to be done,\nbut what volunteers wish to do and most work is welcome.
                                                            \n

                                                            \n

                                                            Sounds great. On the topic of platforms, which platforms does Krita\nsupport right now?

                                                            \n

                                                            That's Linux.
                                                            \nWe prefer our own binary builds in AppImage format because we have to\npatch a lot of the libraries that Krita depends on.
                                                            \nWindows, MacOS, Android.
                                                            \nIf and when iPadOS gets opened up, we might port to iOS.
                                                            \nBut both for iOS and Android, Oh, we also support Chrome OS, but that's\nAndroid.
                                                            \nFor iPadOS and Android, so tablet form factor, we really want to\noptimize our user interface for touch and for that we need to have the\nport to Qt6 done.
                                                            \nSo that's going to take some time.
                                                            \n

                                                            \n

                                                            Sounds like there's a lot of exciting things coming.
                                                            \nI think that's all I have for you today. So I'd like to really thank you\nfor taking the time to speak to us.
                                                            \n

                                                            \n

                                                            It was a pleasure. Um, is there any things we haven't covered that\nyou would like to, uh, talk about?

                                                            \n

                                                            Oh, I want to brag a bit.
                                                            \n

                                                            \n

                                                            Go for it.
                                                            \n

                                                            \n

                                                            Because we have about 7 million users.
                                                            \nThat's quite a lot.
                                                            \nI mean, I used to do commercial software development.
                                                            \nAnd most of the companies we worked for never ever released.
                                                            \nSo that makes it so much more fun to work on.
                                                            \n

                                                            \n

                                                            Yeah, that's genuinely amazing.
                                                            \nAwesome. Thank you very much.

His show was prompted by a\npost we put out entitled Happy\nnew year - should we continue with HPR ?, wherein we asked you to\nvote on the future of HPR. The vote was a not so subtle redirect to our\nupload page.

                                                            \n

                                                            1. More subscribers does not mean more contributors.

                                                            3. Use social media to bring people to HPR and not\ndrive the discussions away from HPR.

It relies on\nthe fact that there are copies of the lost files on the Internet\nArchive, and on a backup disk. These are being copied across to the HPR\nserver and linked into shows again.

Something that allows you to use hotkeys to pause and rewind 10 seconds at a time would be ideal.

There is a difference in the two\norientations in other words. Sometimes it's in the galactic plane, and\nat times it's \"above\" or \"below\".

There seems to be a correlation\nbetween these events - gamma ray exposure and extinctions - though there\nis no certainty that this is so. Extinctions may have multiple causes,\nso the relationship cannot be simple.

The oily substance they produce helps to prevent the\neye surface from drying out by mixing with the tears. It also helps the\neyelids to make an airtight seal when the eyes are closed. There are\nmany functions.

                                                            I'm using text to speech as suggested by Beeza\nin episode hpr4167 ::\nRemoving another obstacle to recording an HPR show but using\npiper from hpr4172 ::\nRe: hpr4072 Piper voice synthesis by Archer72.

                                                            For this tutorial I suggest how it might be possible to use tor browser to download\ndifficult to find public domain works.

                                                            \n

                                                            As well as letting you browse privately, it also enables a SOCKS Proxy which other\napplications can use.

                                                            \n

                                                            Wikipedia maintains a list of List\nof films in the public domain in the United States.

                                                            \n

                                                            I found out about this list after reading Copyright\nin Zombies, Vampires, Frankenstein and More!.

                                                            \n

                                                            Once you have ensured that it's perfectly legal do download the movie\nin your Jurisdiction, then use tor to go to duck duck go video\nsearch.

                                                            \n

                                                            In our hypothetical scenario, say we wanted to download Night\nof the Living Dead, released in 1968 by Director George A. Romero\nand came out of copyright in 1968 due to \"Missing copyright notice and\nerrors from the distributor.\" From List\nof films in the public domain in the United States Night of the\nLiving Dead entered the public domain because the original theatrical\ndistributor, the Walter Reade Organization, neglected to place a\ncopyright indication on the prints. In 1968, United States copyright law\nrequired a proper notice for a work to maintain a copyright\"

                                                            \n

                                                            This is why there are so many variations on zombie movies.

                                                            \n

                                                            In the example ok.ru is the site hosting the movie, and it has a link\nof https://ok.ru/video/foo_bar

                                                            \n

                                                            It would be simple enough to just point yt-dlp - A feature-rich\ncommand-line audio/video downloader, to the url and download it.

                                                            \n

                                                            You could also take advantage of the fact that yt-dlp supports a SOCKS\nproxy.

                                                            \n
                                                            --proxy URL\n    Use the specified HTTP/HTTPS/SOCKS proxy.  To enable SOCKS proxy, specify a proper scheme, e.g.  socks5://user:pass@127.0.0.1:1080/.  Pass in an empty st9ring (--proxy "") for direct connection
                                                            \n

                                                            So if you were to run\nyt-dlp --proxy socks5://localhost:9150 https://ok.ru/video/foo_bar\nit would download the movie via tor.

                                                            \n

                                                            I am in no way condoning the downloading of illegal material, and am\nnot suggesting in any way that you do so.

The format is normally auto detected for input files and guessed from\n    the file extension for output files, so this option is not needed in most cases.\n\n-framerate\n    Set the grabbing frame rate. Default is "ntsc", corresponding to a frame rate of "30000/1001".\n\n-video_size\n    Set the video frame size.\n\n-input_format\n    Set the preferred pixel format (for raw video) or a codec name. This option allows one to select the input\n    format, when several are available.\n\n-thread_queue_size size (input)\n    This option sets the maximum number of queued packets when reading from the file or device. With low\n    latency / high rate live streams, packets may be discarded if they are not read in a timely manner;\n    raising this value can avoid it.\n\n-i filename (input)\n    input file name\n\n-f fmt (input/output)\n    Force input or output file format. The format is normally auto detected for input files and guessed from\n    the file extension for output files, so this option is not needed in most cases.\n\n-c[:stream_specifier] codec (input/output,per-stream)\n-codec[:stream_specifier] codec (input/output,per-stream)\n    Select an encoder (when used before an output file) or a decoder (when used before an input file) for one\n    or more streams. codec is the name of a decoder/encoder or a special value "copy" (output only) to indicate\n    that the stream is not to be re-encoded.\n\n    For example\n\n            ffmpeg -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT\n\n    encodes all video streams with libx264 and copies all audio streams.\n\n    For each stream, the last matching "c" option is applied, so\n\n            ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT\n\n    will copy all the streams except the second video, which will be encoded with libx264, and the 138th audio,\n    which will be encoded with libvorbis.

                                                            We used the v4l2 for the Video4Linux format.\nA frame rate of 30, and input format of mjpg which are limitations of the\ncard. Given the source PAL-I has 625\nlines, a video_size of 720x480 is reasonable. After ffmpeg\ncomplained, I added thread_queue_size of 512 to help out. Then the rest\nis specifying the input for the video, and setting the audio to flac.

                                                            The intention was to put in a tape in the morning before going to\nwork. Swap it for another when I got home, and yet another when I went\nto bed.

                                                            \n

                                                            As there was no mechanism to know when the recording was done, I\nfirst checked the length of the tape by Fast Forwarding it to the\nend.

It would eventually recover after a\nfew days, but I lost a lot of time and couldn't trust the process. I\nchecked the memory and hard disk, even writing to usb and a nas.

                                                            \n

                                                            With each hour of recording coming in at 6.6G, some tapes lead to 60G\nfiles.

                                                            \n

                                                            I suspect that my luks\nencrypted disk was struggled with the huge files that were been\nproduced.

                                                            \n

                                                            So keeping it simple I called out my HP t610\nFlexible Thin Client with 2nd hand 1T hard disk, and set it up with\na clean install of Debian.

                                                            I wanted to be able to\nscrubb\nforward and back, to see if there was anything recorded on the tapes.\nUnfortunately the mkv flac/mjpeg format doesn't allow\nscrubbing,\nso the recorded media first needed to be transcoded to a format that did\nallow scrubbing, but also reduced the file size dramatically.

                                                            \n

                                                            By specifying the filename as next this command converted the media\nto mp4. ffmpeg -i ${next} ${next%.*}.mp4

                                                            \n

                                                            This reduces the size by about 50%.

                                                            This is a fantastic card game suitable for 3 or more players. We've\neven played it with up to 7 players.

                                                            \n

                                                            The game utilizes a standard deck of cards.

                                                            \n

                                                            Each player is dealt 7 cards.

                                                            \n

                                                            The remaining cards form a pile in the center face down.

                                                            \n

                                                            The objective of the game is to have the most sets of cards by the\nend.

                                                            \n

                                                            A set is defined as 4 cards of the same rank, such as all the 3s or\nall the kings. The suits of the cards are irrelevant in this game.

                                                            \n

                                                            Determine who will take the first turn. This player must have a card\nof the rank they intend to ask for in their hand.

                                                            \n

                                                            They then inquire from another player if they have any cards of that\nspecific rank. For example, \"Oscar, do you have any 5s?\" If Oscar has\nany fives, he must give all the cards which have five on them to the\nasking player.

                                                            \n

                                                            The player who has requested the card gets another turn. They can ask\nany of the other players. When a player asks for a card and that player\ndoes not have that card in their hand they say \"Go Fish\", and the player\nwho has asked the question must draw a card from the pile. Their turn is\nover and passes to the next player in a clockwise direction.

                                                            \n

                                                            If a player collects 4 cards of the same rank, they form a set and\nare placed aside. If a player runs out of cards, they can draw one from\nthe pile and ask for cards of that rank. If there are no more cards left\nin the pile, that player is out of the game. But don't worry, you can\nstill win. The game continues until all the cards have been played. Once\nall the cards are played, the player with the most sets wins

                                                            This game is both amusing and challenging, and it will certainly make\nyou laugh as you discover what cards other players hold. For instance,\nif Oscar has one five, Josie has two fives, Al has one five, and Rainy\nhas no fives. Oscar can ask Josie if she has a five, and since she does,\nshe has to give the cards to Oscar. He then gets another turn and asks\nRainy, but she doesn't have any and says \"go fish\". Now Al knows that\nOscar has three fives in his hand. So, when it's Al's turn, he can ask\nOscar if he has any fives, and since he does, he has to hand them over.\nThis way, Al wins that set of cards.

                                                            \n

                                                            Give it a try and you'll find yourself laughing out of frustration.\nI'll include the rules of the game in the show notes.

                                                            My subject today is Piper voice synthesis, continued.\n

                                                            synthesis, I am responding to his comment with a solution. I'm\nglad that Ken
                                                            commented, because I had put the problem on the back\nburner and forgot about it.
                                                            Both of us had the make\ncommand for the Piper github repo fail at 22%.

                                                            \nI ignored it for the time being and compiled Piper for the Raspberry Pi\ninstead.
                                                            Now here is the comment that got me to figure out how to\nget Piper working on my

                                                            Hi Ken, I get the same failure, and found that there was a release in\n2023

                                                            In further conversations with Ken, I found that a vital part of Piper\nvoice
                                                            synthesis had been forgotten. For example, if you are using\nPiper to convert a
                                                            text file to .wav, the command need to include\nthe following:
                                                            input.txt piper executable location, i.e.\n/opt/piper/piper

                                                            \n

                                                            --model, and the model location, i.e.\n/opt/piper-voices/

                                                            \n

                                                            note, the voice used need to include the voice in .onnx format and\nalso the
                                                            voice configuration in .json format

                                                            \n

                                                            --output_file output.wav

                                                            \nThe final script is included in the show notes.\n

                                                            \n
                                                            #!/bin/bash\ncat "$1" | /opt/piper/piper --model /opt/piper-voices/en_US/kusal/medium/en_US-kusal-medium.onnx --output_file output.wav
                                                            \n

                                                            That's it! Now if you had downloaded the voices from hpr4172, there\nshould be a
                                                            successful voice to text output.

                                                            \n

                                                            To put the final touches on 'my' voice, which is the\nen_US-kusal-medium voice,
                                                            processed just a bit with the\nsox program.

                                                            \n
                                                            ## ~/bin/make-my-voice.sh\n#!/bin/bash\n# Add 2 seconds of silence to the beginning of the file\nsox $1 output.wav pad 2\n\n## Reduce clipping\nsox output.wav output-mid.wav vol 0.99\n\n# Reduce the tempo by 12%\nsox output-mid.wav final_output.wav tempo 0.88

                                                            One last thing. It was brought to my attention that the Piper voice,\nBryce 'may'
                                                            sound like William Shatner in the original Star Trek tv\nseries.

                                                            I will put that clip in here and see what the community thinks. Feel\nfree to

In the past I have\nloaded these into a Bash array and turned them into a comma-delimited\nstring, using the parameter substitution capabilities of Bash which can\nadd a comma to each element. The trouble with this is that it leaves a\ntrailing comma which has to be removed. I stumbled upon\npaste as an alternative way of doing this.

                                                            \n

                                                            The first thing that we will need to do is to go to the DuckDNS website, sign in using your preferred method, once you complete the captcha then you will be given your unique token (copy or take a note of it, but don't share this with anybody).

                                                            \n

                                                            Next you will want to create your own unique address, type in your chosen domain and click on Add Domain.

                                                            \n

                                                            Now it is time to setup your Raspberry Pi. Log into your Pi and open a terminal. The first thing that we will do is make sure that it is up to date:

                                                            \nsudo apt update && sudo apt upgrade -y\n

                                                            Install Curl using the command:

                                                            \nsudo apt install curl\n

                                                            You will now create two new folders, the first is where the script will be kept, the second to store the logs:

                                                            \nsudo mkdir /opt/duckdns/ && sudo mkdir /var/log/duckdns/\n

                                                            We need to add a bash script that will update your IP with the DuckDNS service. First of all create a new file called duck.sh with the code:

                                                            \nsudo nano /opt/duckdns/duck.sh\n

                                                            At this point the file is empty, we need to enter in the command below. However you must replace DUCKDNSDOMAIN with the domain that was created on the DuckDNS website and replace DUCKTOKEN with your DuckDNS Token:

                                                            \necho url=\"https://www.duckdns.org/update?domains=DUCKDNSDOMAIN&token=DUCKTOKEN&ip=\" | curl -k -o /var/log/duckdns/duck.log -K -\n

                                                            Now save and exit (ctrl+X, Y, enter on Nano).

                                                            \n

                                                            Next we can set the script's permission so that nobody else will gain access to your token:

                                                            \nsudo chmod 700 /opt/duckdns/duck.sh\n

                                                            Last step: we need to set a cron task so that your Pi will update DuckDNS domain every 5 minutes:

                                                            \nsudo crontab -e\n

                                                            Navigate to the bottom of the page and add the line:

                                                            \n*/5 * * * * /opt/duckdns/duck.sh >/dev/null 2>&1\n

                                                            Save and exit and your dynamic DNS should be up and running within five minutes.

                                                            In the future I plan on doing podcasts on specific Plain Text\nPrograms, some that I wrote and some that were written by others. Any\nprogram that I will discuss will be licensed with a free culture\nlicense.

                                                            \n

                                                            The first thing I want to emphasize about Plain Text Programs is that\nthere's no database like SQL or LLM. All text data is written in plain\ntext files stored on a file system.

                                                            \n

                                                            Now, I love databases. Before I retired I was a database programmer.\nAnd as a database programmer I learned a lot about the difficulties\nmaintaining programs that rely on databases. There's a lot of cool stuff\nyou can do with a database that's just not reasonable to try with plain\ntext. Now that I'm retired I don't really want to work that hard\nanymore. I want programming to be easy and fun.

                                                            \n

                                                            Plain text does not mean there can't be images or other media. Image\nfiles like .jpg or .png can be stored in the file system just like text\nfiles. No worries.

                                                            \n

                                                            A big advantage of Plain Text Programs is portability. To back up a\nworking program you copy the directory tree that holds the program's\nfiles. To install or restore a Plain Text Program copy the tree onto a\nsystem or server.

                                                            \n

                                                            I usually work on Linux using the PHP programming language. This is\nof course my preference. Any language running on any file system can be\nused to write Plain Text Programs.

                                                            \n

                                                            My minimum install will usually have a configuration file, at least\none program file, and a set of text files.

                                                            I also use Plain Text Programs that other programmers wrote

                                                            \n\n

                                                            Links to these programs are in the script.

                                                            \n

                                                            So these are mostly websites or web applications but Plain Text\nPrograms do not have to be outward facing. They can just be an easy\nprogram that you write to automate a task that you have to do\nperiodically. Like my Backup The Web Server program that I wrote in\nbash.

                                                            \n

                                                            I write my Plain Text Programs websites so that updates and additions\nare made with FTP. FTP is a well established secure way to transfer\nfiles from your development system to your web server. Another good\noption, particularly for static websites that are generated on the\ndevelopment system and then mirrored up to the server, is rsync.

                                                            \n

                                                            I believe that simplicity is the key. I have written complicated\nPlain Text Programs including the social network writing game, Collab.\nBut I think a simple one page or few pages design fits the plain text\nparadigm better.

                                                            Well, I'm going to call this a wrap for now. I plan on covering\nspecific Plain Text Programs in future podcasts and I may occasionally\nstep back and look at the big picture or discuss ideas and\nspecifications for future projects.

From the picture droplets of\nliquid can clearly be seen on the right hand connecting terminal\nindicating that the battery is leaking and must be removed before damage\noccurs. On the right hand side of the picture notice the two connectors\nattached to the circuit board that are terminated with unused sockets. I\nhave no idea what these sockets are used for. There are brass pillars\neither side of the connectors. I assume some sort of add on board could\nbe purchased and perhaps this is what the unused connectors are for. I\nalso mention an unpopulated IC socket that can be seen in the top left\nhand side of the picture. This is probably for another optional\nextra.

                                                            MeshCom is a project to exchange text messages via LORA radio\nmodules. The primary goal is to realize networked off-grid messaging\nwith low power and low cost hardware.

                                                            \n

                                                            The technical approach is based on the use of LORA radio modules\nwhich transmit messages, positions, measured values, telecontrol and\nmuch more with low transmission power over long distances. MeshCom\nmodules can be combined to form a mesh network, but can also be\nconnected to a message network via MeshCom gateways, which are ideally\nconnected via HAMNET. This enables MeshCom radio networks, which are not\nconnected to each other via radio, to communicate with each other.\n

                                                            Good Samaritan laws offer legal protection to people who give\nreasonable assistance to those who are, or whom they believe to be\ninjured, ill, in peril, or otherwise incapacitated. The protection is\nintended to reduce bystanders' hesitation to assist, for fear of being\nsued or prosecuted for unintentional injury or wrongful death.
                                                            \n

                                                            \n

                                                            A duty to rescue is a concept in tort law and criminal law that\narises in a number of cases, describing a circumstance in which a party\ncan be held liable for failing to come to the rescue of another party\nwho could face potential injury or death without being rescued. The\nexact extent of the duty varies greatly between different\njurisdictions.
                                                            \nA duty to rescue arises where a person creates a hazardous situation. If\nanother person then falls into peril because of this hazardous\nsituation, the creator of the hazard – who may not necessarily have been\na negligent tortfeasor – has a duty to rescue the individual in\nperil.
                                                            \nSpouses have a duty to rescue each other in all U.S. jurisdictions.

                                                            \n

                                                            A tort is a civil wrong, other than breach of contract, that causes a\nclaimant to suffer loss or harm, resulting in legal liability for the\nperson who commits the tortious act. Tort law can be contrasted with\ncriminal law, which deals with criminal wrongs that are punishable by\nthe state. While criminal law aims to punish individuals who commit\ncrimes, tort law aims to compensate individuals who suffer harm as a\nresult of the actions of others.
                                                            \nIn common, civil, and mixed law jurisdictions alike, the main remedy\navailable to plaintiffs under tort law is compensation in damages, or\nmoney.

                                                            \n

                                                            Dirt Simple Photo Gallery is the program that started me down the\nPlain Text Programs path. It predates my own thinking about Plain Text\nPrograms by at least a decade. Ever since I wrote it I use it all the\ntime. It is now my preferred web page generator for all kinds of web\npages, not just galleries.

                                                            \n

                                                            Like most of my programs I wrote it because I needed it. Vivian and I\nwere putting on music events like Blues Fest, Sunday In The Park, Jazz\nThursday, New Jazz In Jonesboro, and Bebopalooza. I recorded all the\nshows. Sometimes video, always audio. And we loved taking pictures of\nthe musicians singing and playing.

                                                            \n

                                                            After the shows we would dump the photo files to a hard drive, make\nall the original photos read only, and back them up to a CD or DVD. We\nreally enjoyed scrolling through the photos, picking the ones we liked,\ncropping them and enhancing them, and resizing them for the\ninternet.

                                                            \n

                                                            And then that's where it fell apart. We recorded the show. We took\nthe pictures. We cropped the pictures and had them ready to go for our\nDelta Boogie website. And we didn't want to write the html.

                                                            \n

                                                            Some days we would have five or six bands playing. We usually had ten\nto twenty photos of each band that we picked out of hundreds of photos\ntaken. Do the math. That's a lot of typing HTML code like a href =, img\nsrc, etc. A lot a captions to write. A lot of work to get done in a\nweek. Because the next weekend we had another show. Another set of\nphotos. Another bunch of html backlog.

                                                            \n

                                                            And the thing I found out. If we didn't get the pages posted right\naway we almost never had time to post them later. I mean we had kids to\nraise, cooking to do, cars to fix, school to attend, not to mention\nwork.

                                                            \n

                                                            So, I loved writing programs more than I loved marking up html. And I\ncould write one program and avoid marking up tons of html. And so I\nwrote the Dirt Simple Photo Gallery.

                                                            \n

                                                            Even back in the dark ages of the internet also known as the nineties\nthere were photo gallery programs. And just like today they were\ncumbersome and running them was a lot like data entry. You know what I\nhate worse than writing html? Data entry.

                                                            \n

                                                            I had this idea. I would take all the photos we had ready for a\ngallery and I would upload them to a directory on our server. Then I\nwould upload an index.php file and we'd have a photo gallery.

                                                            \n

                                                            And that's just how Dirt Simple Photo Gallery works. And if that's\nreally all you need you're done.

                                                            \n

                                                            It wasn't quite all we needed. So I added a title.txt file and a\nnotes.txt file so there could be a bit more than just the photos and\ncaptions on the web page. I was careful that I didn't have to write any\nhtml in the notes.txt file. The program even automatically turns copy\nand pasted links into hot links.

                                                            \n

                                                            Now, you can include html in the notes.txt file. You can even embed\niframes if you want to include an audio or video player. But you don't\nhave to. Also, iframe embeds are just a copy and paste exactly like\nlinks. Easy peasy.

                                                            \n

                                                            There's also the problem of the captions and the sort order of the\nphotos.

                                                            \n

                                                            Captions

                                                            \n

                                                            I use the file names to carry the meta data required for captions and\nsort order.

                                                            \n

                                                            These are the characters I use in the file names. Alphanumeric,\ncommas, apostrophes, dashes, and underscores. I don't use spaces but the\nunderscores are converted to spaces in the captions. I use Thunar and I\nlove the bulk rename option where I can search and replace a set of file\nnames and change all the spaces into underscores.

                                                            \n

                                                            I have code that allows you to include special characters in your\ncaptions by using html character sets but it's confusing to think about.\nAnd I discovered the only special characters I really needed were\ndashes, commas, and apostrophes. All three of these characters are legal\nin file names on all major systems. Dashes are not problematic. Commas\ncan cause problems if you are using comma delimited data but, I'm not,\nso no worries. Apostrophes can also be an issue because in php they are\nused as single quotes and can be used to delimit strings in the code.\nThere is a way around this with php. Use double quotes to surround the\nentire string. If there is a place inside of that string where you would\nuse single quotes, which is not uncommon in html, replace the single\nquotes with escaped double quotes, that is \". So that's what I did.

                                                            \n

                                                            So now I can use all the apostrophes I want in my file names and they\nfly right through my code, never accidentally truncating a string and\nthrowing errors.

                                                            \n

                                                            Commas and apostrophes are important in captions. Captioning group\nshots without commas leads to misunderstanding people's names. And if\nyour caption has a possessive in it like Joe's Garage leaving the\napostrophe out is just wrong.

                                                            \n

                                                            Using double quotes in a file name will truncate strings in the php\ncode and throw errors. Usually, anywhere you would want a double quote a\nsingle quote will do.

                                                            \n

                                                            There are other special characters, like dashes, that aren't\nproblematic. Forward slashes and back slashes should not be used in file\nnames ever. Some special characters may work on some systems and not on\nothers. I've been using this program for almost 25 years and I really\nwant commas and apostrophes and don't really care about other special\ncharacters in captions. You may have special needs for special\ncharacters I don't. That's why it's open source. If you need something\nthe program isn't designed to provide test it. Fix it. Right now there\nare fewer than 100 lines of code in the program. I have confidence in\nyou.

                                                            \n

                                                            \n

                                                            Default sorting of images is alphabetical by file name. If you just\nname your files with good captions and don't add any numbers as a prefix\nthat's what you'll get. Alphabetical by caption. This may be just what\nyou need.

                                                            \n

                                                            If, however, you want some other sort order you can prefix your files\nwith nnn- where n is any integer.

                                                            \n

                                                            000-filename.ext displays the picture at the top of the page. If the\nphoto is narrow enough, the text from notes.txt will wrap around it to\nthe left.

                                                            \n

                                                            All the photos numbered 001- to 999- will display in a single column\nbelow the text. Unnumbered photos will also display below the text in\nalphabetical order. So if you want a photo at the top of the page add\nthe prefix 000- to the file name. If alphabetical order is what you want\nfor the rest of the photos you don't have to rename them.

                                                            \n

                                                            Permitted extensions are jpg, png, or gif. (It's hapeg stupid!) It's\neasy to add other permitted extensions in the code but, of course, they\nhave to be rendered by a browser. I did not include the jpeg extension\nchoosing to rename jpeg files to jpg. This made it slightly easier to\ncode.

                                                            \n

                                                            There is a config.inc file where you can set your table width. The\ndefault is 700. I resize my photos to be 600 max width. I usually use\njpg files with a quality level of 90. This reduces storage space and\nenables fast loading of images. The config.inc file also allows you to\nchange background color, text color, link color, etc. There is also a\nCSS section in the config.inc file so you can change the font, the\nheadline sizes, etc. Or add your own CSS.

                                                            \n

                                                            If you have trouble getting the text wraparound to look good on your\npage there is a way to disable it in the config.inc file.

                                                            \n

                                                            Install the page with ftp. Make a directory, where you want it on\nyour website, and give it a good name. Upload index.php, title.txt,\nnotes.txt, config.inc, and the image files into the directory. Go to\nyour website and check it out. That's it.

                                                            \n

                                                            Page maintenance is the same. Fix captions by renaming files. Add and\ndelete images. Update the title or the text in notes.txt and upload the\nchanges. Change the font, colors, or CSS in config.inc and upload the\nchanges.

                                                            This is a look at the very first serial of Doctor who, and how the\ncast was first put in place. It is in many ways an unlikely story for a\nshow that has gone on for 60 years and counting. I find the early\nstories to be charming and worth a look, and many things from these\nearly stories come back in later stories as well.

                                                            Overview

                                                            \n

                                                            In this episode we will continue looking at basic filters. Then we\nwill start looking at the feature that makes jq very\npowerful, the ability to transform JSON from one form to another. In\nessence we can read and parse JSON and then construct an alternative\nform.

                                                            \n

                                                            More basic filters

                                                            \n

                                                            Array/String Slice:\n.[<number>:<number>]

                                                            \n

                                                            This filter allows parts of JSON arrays or strings to be\nextracted.

                                                            \n

                                                            The first number is the index of the elements of the array or string,\nstarting from zero. The second number is an ending index, but it means\n\"up to but not including\". If the first index is omitted it refers to\nthe start of the string or array. If the second index is blank it refers\nto the end of the string or array.

                                                            \n

                                                            This example shows using an array and extracting part of it:

                                                            \n
                                                            $ x="[$(seq -s, 1 10)]"\n$ echo "$x"\n[1,2,3,4,5,6,7,8,9,10]\n$ echo "$x" | jq -c '.[3:6]'\n[4,5,6]
                                                            \n

                                                            Here we use the seq command to generate the numbers 1-10\nseparated by commas in a JSON array. Feeding this to jq on\nits standard input with the slice request '.[3:6]' results\nin a sub-array from element 3 (containing value 4), up to but not\nincluding element 6 (containing 7). Note that using the\n'-c' option generates compact output, as we discussed in\nthe last episode.

                                                            \n

                                                            For a string, the idea is similar, as in:

                                                            \n
                                                            $ echo '"Hacker Public Radio"' | jq '.[7:10]'\n"Pub"
                                                            \n

                                                            Notice that we provide the JSON string quotes inside single quotes\nfollowing echo. The filter '.[7:10]' starts\nfrom element 7 (letter \"P\") up to but not including element 10\n(letter \"l\").

                                                            \n

                                                            Both of the numbers may be negative, meaning that they are offsets\nfrom the end of the array or string.

                                                            \n

                                                            So, using '.[-7:-4]' in the array example gives the same\nresult as '.[3:6]', as do '.[3:-4]' and\n'.[-7:6]'. This example uses the x variable\ncreated earlier:

                                                            \n
                                                            $ for f in '.[-7:-4]' '.[3:6]' '.[3:-4]' '.[-7:6]'; do\n> echo "$x" | jq -c  "$f"\n> done\n[4,5,6]\n[4,5,6]\n[4,5,6]\n[4,5,6]
                                                            \n

                                                            Similarly, using '.[-12:-9]' gives the same result as\n'.[7:10]' when used with the string.

                                                            \n
                                                            $ echo '"Hacker Public Radio"' | jq '.[-12:-9]'\n"Pub"
                                                            \n

                                                            As a point of interest, I wrote a little Bash loop to show the\npositive and negative offsets of the characters in the test string -\njust to help me visualise them. See the footnote1 for details.

                                                            \n

                                                            Finally, here is how to get the last character of the example string\nusing positive and negative offsets:

                                                            \n
                                                            $ echo '"Hacker Public Radio"' | jq '.[18:]'\n"o"\n$ echo '"Hacker Public Radio"' | jq '.[-1:]'\n"o"
                                                            \n

                                                            Array/Object Value Iterator:\n.[]

                                                            \n

                                                            This filter generates values from iterating through an array or an\nobject. It is similar to the .[index] syntax we have\nalready seen, but it returns all of the array elements:

                                                            \n
                                                            $ arr='["Kohinoor","plastered","downloadable"]'\n$ echo "$arr" | jq '.[]'\n"Kohinoor"\n"plastered"\n"downloadable"
                                                            \n

                                                            The strings in the array are returned separately, not as an array.\nThis is because this is an iterator, and its output can be linked to\nother filters.

                                                            \n

                                                            It can also be used to iterate over values in an object:

                                                            \n
                                                            $ obj='{"name": "Hacker Public Radio", "type": "Podcast"}'\n$ echo "$obj" | jq '.[]'\n"Hacker Public Radio"\n"Podcast"
                                                            \n

                                                            This iterator does not work on other data types, just arrays and\nobjects.

                                                            \n

                                                            An alternative iterator .[]? exists which ignores\nerrors:

                                                            \n
                                                            $ echo "true" | jq '.[]'\njq: error (at <stdin>:1): Cannot iterate over boolean (true)
                                                            \n

                                                            Ignoring errors:

                                                            \n
                                                            $ echo "true" | jq '.[]?'
                                                            \n

                                                            Using multiple filters

                                                            \n

                                                            There are two operators that can be placed between filters to combine\ntheir effects: the comma (',') and the\npipe ('|').

                                                            \n

                                                            Comma operator

                                                            \n

                                                            The comma (',') operator allows you to chain together\nmultiple filters. As we already know, the jq program feeds\nthe input it receives on standard input or from a file into whatever\nfilter it is given. So far we have only seen a single filter being\nused.

                                                            \n

                                                            With the comma operator the input to jq is fed to all of\nthe filters separated by commas in left to right order. The result is a\nconcatenation of the output of all of these filters.

                                                            \n

                                                            For example, if we take the output from the HPR stats page which was\nmentioned in part 1\nof this series of shows, and store it in a file called\nstats.json we can view two separate parts of the JSON like\nthis:

                                                            \n
                                                            $ curl -s https://hub.hackerpublicradio.org/stats.json -O\n\n$ jq '.shows , .queue' stats.json\n{\n  "total": 4756,\n  "twat": 300,\n  "hpr": 4456,\n  "duration": 7640311,\n  "human_duration": "0 Years, 2 months, 29 days, 10 hours, 18 minutes and 31 seconds"\n}\n{\n  "number_future_hosts": 6,\n  "number_future_shows": 18,\n  "unprocessed_comments": 0,\n  "submitted_shows": 0,\n  "shows_in_workflow": 51,\n  "reserve": 20\n}

                                                            This applies the filter .shows (an object\nidentifier-index filter, see part 2)\nwhich returns the contents of the object with that name, then it applies\nfilter .queue which returns the relevant JSON object.

                                                            Pipe operator

                                                            \n

                                                            The pipe ('|') operator combines filters by feeding the\noutput of the first (left-most) filter of a pair into the second\n(right-most) filter of a pair. This is analogous to the way the same\nsymbol works in the Unix shell.

                                                            \n

                                                            For example, if we extract the 'shows' object from\nstats.json, we can then extract the value of the\ntotal' key' as follows:

                                                            \n
                                                            $ jq '.shows | .total' stats.json\n4756
                                                            \n

                                                            Interestingly, chaining two object identifier-index filters\ngives the same output:

                                                            \n
                                                            $ jq '.shows.total' stats.json\n4756
                                                            \n

                                                            (Note: to answer the question in the audio, the two filters shown can\nalso be written as '.shows .total' with intervening\nspaces.)

                                                            \n

                                                            We will see the pipe operator being used in many instances in\nupcoming episodes.

                                                            \n

                                                            Parentheses

                                                            \n

                                                            It is possible to use parentheses in filter expressions in a similar\nway to using them in arithmetic, where they group parts together and can\nchange the normal order of operations. They can be used in other\ncontexts too. The example is a simple arithmetic one:

                                                            \n
                                                            $ jq '.shows.total + 2 / 2' stats.json\n4757\n$ jq '(.shows.total + 2) / 2' stats.json\n2379
                                                            \n

                                                            Examples

                                                            Here we are using a file called countries.json obtained\nfrom the GitHub\nproject listed below. This file is around 39,000 lines long so it is\nnot being distributed with the show. However, it's quite interesting and\nyou are encouraged to grab a copy and experiment with it.

                                                            • Note that we used a comma operator between the\nfilters.
                                                              • \n

                                                            What Is A Plain Text Program?

                                                            \n

                                                            Today I'm going to go into more detail about what I mean when I say\nPlain Text Program. I want to emphasize that this is just me. Others may\nhave different ideas on this topic. This is how I try to write Plain\nText Programs. I will feature other people's work that I still consider\nto be Plain Text Programs that do not follow all of these\nguidelines.

                                                            \n

                                                            I want to thank the hosts on the monthly HPR Community News podcast\nfor inspiring me. They had questions. I also want to thank those making\ncomments. I'm new to Hacker Public Radio and I will try to be more\ntimely responding to comments in the future.

                                                            \n

                                                            What Is A Plain Text File?

                                                            \n

                                                            Text files are usually edited in a text editor or in a word processor\nand saved with the .txt extension. They consist of a string of\ncharacters. Text files can be divided into lines using the newline\ncharacter, \\n, or the carriage return and newline\ncharacters, \\r\\n. You don't have to type these characters.\nYour editor puts them in for you.

                                                            \n

                                                            Text files do not have to use the .txt extension. Most programming\nfiles, like .php or .c files are plain text. I will only be discussing\nprograms that are open source and that store their code in text\nfiles.

                                                            \n

                                                            Plain text configuration files often have no extension. For my Plain\nText Programs I use config.inc.

                                                            \n

                                                            There is no difference between text files and plain text files.\nPeople often say plain text files to distinguish them from word\nprocessor files like .doc or .odt files.

                                                            \n

                                                            Plain Text Programs use text files to store text like a title or a\nblog post. When I talk about Plain Text Programs I also mean something\nmore than this. That's what this podcast is about.

                                                            \n

                                                            No Database?

                                                            \n

                                                            Plain Text Programs do not use a database like mysql or postgres.\nAlso the file system does not imitate a database, creating keys,\nindexing, etc.

                                                            \n

                                                            Instead the file system performs the database functions by accessing\nfiles which can be text files, graphics files, or other files. These\nfiles can be all in one directory or in multiple directories in a single\ndirectory tree.

                                                            \n

                                                            If password security is required in a Plain Text Program that runs on\nthe internet I make an exception to the single tree rule to allow\npasswords to be stored outside of the webspace.

                                                            \n

                                                            So the assets a Plain Text Program accesses are just files in the\nfile system.

                                                            \n

                                                            No HTML Or Other Markup\nRequired

                                                            \n

                                                            I have no rule against allowing html or other markup. But I do not\nassume that the maintainer knows how to do this or wants to learn it.\nThe reason I started writing Plain Text Programs was to avoid html\nmarkup. I want to be able to type text files, save them, and upload\nthem, without being concerned about anything except the text itself.

                                                            \n

                                                            The text files holding the content are written in block paragraph\nstyle with a blank line between paragraphs. Text files are not required\nin a Plain Text Program but most Plain Text Programs do use some text\ndata which should be stored in text files.

                                                            \n

                                                            If this is a web application, links can be copied and pasted from the\nbrowser with no additional markup required.

                                                            \n

                                                            Other assets in the directory, like .gif, .jpg, or .png images,\ndisplay automatically.

                                                            \n

                                                            I use the file names for meta data like title, caption, or sort\norder. I can also sort chronologically using the file timestamps.

                                                            \n

                                                            If there is a hierarchy of directories the program can use the\ndirectory name of the child directories for the link text. For instance\nthe Delta Musicians directory tree can have a Table Of Contents at the\ntop level that lists the musicians in alphabetical order. Each musician\ngets their own subdirectory and the name of that subdirectory is used to\ngenerate the link and link text for that page.

                                                            \n

                                                            Then, each page can use Dirt Simple Photo Gallery and the program\ngenerates the caption from the image's file name.

                                                            \n

                                                            All configuration is also done in a text file. I use a well\ndocumented config.inc file that initializes php variables.\nThe maintainer of the application is never required to edit source\ncode.

                                                            \n

                                                            Does Plain Text\nMean There Is No GUI Interface?

                                                            \n

                                                            No. I write mostly web apps so they run in the browser interface.\nAlso, Plain Text Programs do not require a GUI. It could run in a\nterminal or as a cron job. The program could play a music playlist or\nrun a slideshow with no input at all.

                                                            \n

                                                            What Do\nI Have To Know To Maintain A Plain Text Program?

                                                            \n

                                                            The maintainer of the program will have to be able to 1. Create and\nedit text files in a text editor or word processor 2. Copy and paste\nlinks, iframe embeds, file names, titles, etc. 3. Rename files 4. Upload\nand download with ftp

                                                            \n

                                                            Executive Summary

                                                            \n

                                                            A Plain Text Program does not use a database like sql. Instead it\nstores the assets in the file system and accesses them using the file\nsystem.

                                                            \n

                                                            A Plain Text Program does not require html or other markup. Text\nassets are written in block paragraph format. If the maintainer prefers\nto use a word processor instead of a text editor that's fine as long as\nthe files are saved as text files with the .txt extension. Most word\nprocessors support this.

                                                            \n

                                                            Plain Text Programs can support links if the links are copied and\npasted into the text file with no markup required.

                                                            \n

                                                            Plain Text Programs can support iframe embeds if the embed code is\ncopied and pasted onto its own line in the text file.

                                                            \n

                                                            All of the assets for a Plain Text Program are stored in a single\ndirectory tree. This is one of the main advantages of Plain Text\nPrograms because it makes them easy to backup and restore so they are\nvery portable. I sometimes make an exception to this if I want to save a\npassword on a webserver outside of the webspace.

                                                            \n

                                                            A Plain Text Program uses the file and directory names for meta data\nlike titles, captions, or sort order. The file timestamps can be used\nfor chronological sorting.

                                                            \n

                                                            All configuration is done by editing a well documented text file. The\nmaintainer should not have to edit the program code.

                                                            \n

                                                            The maintainer should be allowed to edit the program code. I will\nonly discuss open source programs that store the program itself in text\nfiles.

We also had a\nlot of changes due to the ongoing Internet Archive outage that is still\nimpacting us. A quick fix was to host the 10 day feed directly from the\nHPR server, but since then we have made all the media available on the\nHPR Community Content Delivery Network.

I\nfirst offered help to Ken in 2012 in response to an appeal he made. We\nmet at OggCamp in that year, and I joined the Community News recording\nfor episode 1066 in September\n2012. My first show was 1091 in October\nthat year.

                                                            • Cost: £25

                                                            • Description: It has a single button used to turn it on and to\nadjust the heat level.

                                                            • It has three different USB sockets. These are used when either\ncharging the hand warmer or using it as a power bank to charge other\ndevices.

                                                            \n

                                                            During OggCamp I mentioned to Ken that I had an electric hand warmer\nand he asked me if it was any good. He suggested I do a long term\nproduct review of it. So here is my review

                                                            \n

                                                            I do lots of dog walking and suffer from cold hands.

                                                            \n

                                                            I've had different hand warmers over the years:

                                                            \n
                                                              \n
                                                            • Ones that you boil in water. Don’t last long
                                                              • \n
                                                            • One that is activated by removing from its packet. Lasts for many\nhours actually too long. They seems very wasteful as they are single\nuse.
                                                              • \n
                                                            • Zippo hand warmer works well but is a faff to setup and sometimes\ngoes out.
                                                              • \n
                                                            \n

                                                            This electric hand warmer is by far the best solution I've found.

                                                            \n

                                                            It saved me twice during OggCamp as I used it on two occasions to top\nup my phone. When arriving and leaving OggCamp.

                                                            \n

                                                            This was the first time I’d used the hand warmer to charge anything.\nI was very glad it worked.

                                                            \n

                                                            At the time of purchase I was rather sceptical about the whole idea\nof electric hand warmers.

                                                            \n

                                                            The batteries are not used in ideal conditions. They get very hot and\nwhen in use a lot of current is drawn from them.

                                                            \n

                                                            My Hand warmer is now almost 4 years old and is still going strong\nwith no noticeable degradation in capacity.

                                                            \n

                                                            It has a rated capacity is 10,000 mAh. The highest charge it achieved\nwas about 1 year into use. It accepted 8034 mAh of charge. I haven’t\nchecked again since November 2021. However it still continues to last\nmany hours / multiple dog walks.

                                                            \n

                                                            I always get a bit nervous over the summer months as it is left for a\nnumber of months unused. Luckily living in Scotland I don’t need to wait\nlong until the weather gets cold. Did I mention before about the\nhorrible weather in Scotland?

                                                            \n

                                                            How I look after the battery

                                                            \n
                                                              \n

                                                            • Always wait for the battery to return to room temperature before\nputting it on charge.

                                                              • \n

                                                            Today I will talk about digitizing analog photos. I will talk about\ntwo methods.

                                                            \n

                                                            I have scanners from different manufacturers, flat bed scanner and\ndedicated film scanner. Each scanner is delivered with software. Each\nsoftware is generally good. But it is a problem to manage several\nsoftware. Secondly, none of them works for Linux operating system. I\nwanted to simplify my software learning, so I wanted one software for\nall my existing and any future scanner. Secondly I intended to migrate\nto a Linux operating system, which I now have done.

                                                            \n

                                                            Those two requirements lead me to switch over to VueScan software. I\nhad tested VueScan before and also gotten recommendations from\nphotographic friends. VueScan is a proprietary software made by a small\nfamily run company. It’s available for Linux, Windows and macOS. VueScan\nsupports very many hardware scanners. I do not know about any better\nsoftware for Linux and is maybe also the best choice for any operating\nsystem. I do not regret my switch to VueScan.

                                                            \n

                                                            A second method to digitize photos is reproduction with a camera.\nThat is to use a camera to shoot a photo of the photo.

                                                            \n

                                                            Some say it is the superior technology. I don’t know. But as I am\ncoming from the scanning technology and starting to explore the repro\ntechnology, I will give my early thoughts from that perspective.

                                                            \n

                                                            My initial plan has been to use repro photography for prints that are\nglued into albums and therefore difficult to manage in the scanner. It\nis also an excellent method to digitize other papers in book format. But\nI have not really started to do that.

                                                            \n

                                                            However, a while ago I started to look into 6x9 cm negatives. My\nscanner can just manage 6x9. But I do not have a fixture for 6x9. So it\nis both somewhat tricky to position the negative as well as to keep it\nflat. A thin plexiglass plate might be possible to use to keep it flat.\nEven without plexiglass, I have tested I can get well acceptable result\nwith the scanner.

                                                            \n

                                                            I started to try out the repro method. I have not come so far in my\ntrials that I can decide which is the best method for me.

                                                            \n

                                                            My camera is a modest camera compared to state of the art. My flat\nbed scanner should give better or comparable resolution than my modest\ndigital camera. The fixture I have for repro do not keep the negative\nfully flat, because 6x9 is a rather big size. So I plan to explore if I\ncan improve quality with a plexiglass plate above the negative.

                                                            \n

                                                            An issue with the repro method is to keep all angles in control, to\nmount the camera in exactly correct angle in relation to the object.\nFocus can also be another issue. I consider it is better to use manual\nfocus rather than auto focus. When I take the repro photos, I have the\ncamera connected to a laptop and I use the Entangle software to control\nthe camera settings. I can use the camera live view to position the\nobject as well as to focus.

                                                            \n

                                                            I use RawTherapee software to convert the negative photo to a normal\nphoto. RawTherapee comes with pre-installed profiles for this process.\nThe default profile values can be adjusted and also stored as new\npersonal profiles.

                                                            \n

                                                            A major advantage of the repro method compared to the scanner method\nis the speed. Once all is configured, it takes one hundred of a second\nor so to do the digitize itself, while it can take minutes with the\nscanner.

                                                            \n

                                                            I use digiKam as my photo catalog software.

                                                            \n

                                                            All software I currently use with the exception of VueScan are free\nand open source. I use all on Linux operating system, some of them are\navailable on other platforms. I include links to their websites in the\nshow notes.

                                                            Guix has a graphical text based installer. It is reminiscent of the mid to late 90s Debian installers. Even with its old school feel, the installer is very nice. It is well laid out, has good onscreen description for each step of the installation process, and provides ample configuration selections from language, to to key board layout, to desktop and software selection.

                                                            Privacy is the ability of an individual or group to seclude\nthemselves or information about themselves, and thereby express\nthemselves selectively.

                                                            Today I want to talk about why digitizing analog photos.

                                                            \n

                                                            Three years ago, I wrote a chapter in the annual book for a home\nvillage association. The chapter was about life in a small village in\nthe 1930's. In addition to the text I had a couple of black and white\nphoto prints from those days.

                                                            \n

                                                            I said black and white. But honestly, an eighty year old black and\nwhite print is not only black and white. Because of aging, type of paper\nand development method, the black and white print has colours. Should\nthe photos in the book chapter be of best black and white photo quality,\nor should they reflect the prints as they are at the time of the book\nrelease?

                                                            There is no right or wrong answer into that question. But it relates\nto the topic, why digitize?

                                                            \n

                                                            I have found the web site \"Preserving history. How to Digitally\nArchive and Share Historical Photographs, Documents, and Audio\nRecordings\".

                                                            \n

                                                            The main focus is photographs, but as the title states it is also\nabout documents and audio. The web site is written and organized as a\nbook and is a very comprehensive and useful resource. It is a few years\nold but is still to a large extent accurate and relevant. The exact\ndetails, which equipment, formats, settings and so on can be discussed.\nAnd as technology has evolved, what the book describes as best has to\nsome extent changed so the best practise can now in some cases be seen\nas good practise.

                                                            \n

                                                            The book has a chapter titled \"Historical Archive Versus Personal\nPhotograph Collection\".

                                                            \n

                                                            The historical archive is about to preserve the object in every\ndetail, e.g. colours, scratches, borders and dimensions. It is\napplicable for true archives, like museums and other public\narchives.

                                                            \n

                                                            The other reason to digitize is of personal and family reasons. In\nthis scope, the focus is to have good photos. This approach gives better\nflexibility in method, equipment and settings, and in general the work\nwill probably be less time consuming.

                                                            \n

                                                            So the take away from this episode is that I recommend you to give\nthe purpose of why you digitize photos a thought before you start a big\ndigitizing project. And that you need to balance any desire to make the\nbest possible archival copy with the best possible equipment and all\ntime in the world with what is realistic for you, and what is good\nenough. And at the other end, the happiness to have and share a digital\nphoto copy of any quality is better than none at all, but considering a\nbit more of work and attention may improve the quality\nsignificantly.

                                                            \n

                                                            Finally, I also want to give a few remarks to my own episode number\n4244.

                                                            \n

                                                            I talked about placing the negative or positive in direct contact to\nglass under or above it. Be observant, there is a risk this will create\nNewton rings which can affect the result in a not acceptable way.

                                                            \n

                                                            The problem that the object is not totally flat in a flat bed scanner\nshould in most cases not be a problem because the scanners are normally\ndesigned to manage a bit of focus depth.

                                                            \n

                                                            Remarks on my repro setup:

                                                            \n

                                                            My digital camera is mounted on a repro stand. The stand is similar\nto the stand used in an analog darkroom.

                                                            \n

                                                            The \"duplication direction\" is opposite to the analog darkroom: The\ncamera is mounted on the stand, while the object to be duplicated is\nplaced on the base plate.

                                                            \n

                                                            I have a light table on the base plate when a negative or positive is\nduplicated.

                                                            \n

                                                            Mounted on the camera, depending on lens, may an extension tube be\nneeded to achieve the macro distance to duplicate a small object.

                                                            \n

This is when\nmany of the great authors developed their craft and became famous, and\nin turn set the ground for science fiction going forward.

All the\nprocessing will happen first, and then all the checks will be done at\nthe same stage just prior to posting. For this to work we need help\nfinding a simple manageable WYSIWYG editor that can produce sane HTML\nwhen the host uploads the show. We also need a new system to distribute\nthe files from an origin to all the mirrors.

                                                            Episode 4 - Embed Mastodon\nThreads

                                                            \n

                                                            This is Episode 4 of the Plain Text Programs Podcast hosted at Hacker\nPublic Radio. As always I will include links with the show notes rather\nthan reading them on the podcast except there will be one exception to\nthat today, the link to my Plain Text Blog, home.gamerplus.org.

                                                            \n

                                                            My blog and this podcast were my inspiration for writing the Embed\nMastodon Threads program. Besides posting the show notes at Hacker\nPublic Radio where they have a comments section I also post them at my\nblog. Then I make a Mastodon post that includes a link to the show notes\non my blog and designate it as being the comment thread for that episode\nof the podcast. I also post a link to the comment thread on Mastodon in\nmy show notes. Or at least I did in the past.

                                                            \n

                                                            It came to mind that it would be nice to be able to display the\ncomment thread at the bottom of the blog post. So I made a Mastodon post\nabout this, and I quote.

                                                            \n
                                                            \n

                                                            So here's my idea.

                                                            \n

                                                            I want to use mastodon toots as a comment thread for my blog\nposts.

                                                            \n

                                                            At the bottom of the blog post I want to embed the toot and the\nreplies.

                                                            \n

                                                            I can pull the toot id from the embed code.

                                                            \n

                                                            Then I want to make a database query to get all the replies to that\ntoot.

                                                            \n

                                                            Then I can generate the embed codes needed to show the toot and all\nthe replies.

                                                            \n

                                                            I'm a mysql guy, not postgres. Also a Mastodon newb.

                                                            \n

                                                            I want to know how to get the reply ids for a toot.

                                                            \n

                                                            Any help, links, etc?

                                                            \n

                                                            End quote.

                                                            \n

                                                            I immediately got responses from some programmers expressing interest\nin the idea and giving good advice.

                                                            I did some research based on their suggestions. I had a good night's\nsleep. And then I made another post in the morning. And I quote.

                                                            Mastodon is so great.

                                                            \n

                                                            I had this idea last night and fiddled around with it long enough to\nrealize I was doing it wrong.

                                                            \n

                                                            So I made a post on Mastodon and almost immediately got help.

                                                            \n

                                                            I found some good info on the Mastodon API.

                                                            \n

                                                            I wake up this morning to more help and I found out about using curl\nin php to make https requests.

                                                            Then a musician friend of mine who I've been following since before\nMastodon sends a working example, with code, in a javascript\nenvironment.

                                                            And I've got a plan.

                                                            So I looked into tootcli and the Mastodon API and I realized that I\ndidn't need to access the database for my program, I could just use the\nAPI.

                                                            My second clue came from EcksDy. And I quote.

                                                            \n

                                                            So then I started to research using curl in PHP to retrieve json data\nfrom the Mastodon API and that's what I went with.

                                                            \n

                                                            I set up a testbed and Malin chimed in with test results. He\ncontinued to help with testing and ideas throughout the rest of the\nproject.

                                                            \n

                                                            That's why Mastodon is so great! Way better than consulting an AI\nbot.

                                                            \n

                                                            So I had my work cut out for me. Here is where this program is like\nmy Plain Text Programs. I work hard, up front, until I am convinced that\nI have an idea that will be easy to implement. This is much easier than\ndoing it the hard way first and then rewriting the program later after\nit becomes difficult to maintain.

                                                            \n

                                                            I said I had a plan. This was my plan.

                                                            \n

                                                            Write a PHP program that will generate a webpage that can be embedded\nin an iframe. This program will take a link as a parameter included in\nthe url.

                                                            \n

                                                            Get that link from the Mastodon embed code for the parent post.

                                                            \n

                                                            Use the API to retrieve the data associated with the parent post\nincluding the replies.

                                                            \n

                                                            Then generate the page by inserting the appropriate data into\nMastodon's existing embed structure.

                                                            \n

                                                            That's kind of a broad framework but it certainly seemed doable. And\nit was.

                                                            \n

                                                            So first I wanted to make the API call so I could look at the\ndata.

                                                            How to easily create cURL API requests in PHP (Wordpress, Laravel,\nSymfony) https://www.youtube.com/watch?v=iRLgEWMNA6w&t=602s

                                                            \n

                                                            He recommended that you use curl in the terminal to test your API\ncall. Then you use a web app called Curl-to-PHP to generate your PHP\ncode to make the same API call from your program.

                                                            \n

                                                            My first time consuming stumbling block was what I call the problem\nwith the colon.

                                                            \n

                                                            There are some great documents detailing the syntax for API calls\nwhich I will link to in the show notes.

                                                            \n

                                                            And where you are supposed to insert an id they show that as :id.

                                                            \n

                                                            Like an idiot I thought the colon was part of the syntax, not as they\nintended, a marker to indicate insert your id here. This is why I like\nto see actual code examples in syntax documents.

                                                            \n

                                                            Anyway I couldn't get it to work so I searched around until I found\nsome code examples and that turned on the lightbulb in my head.

                                                            \n

                                                            Now I was able to make API calls using curl in the terminal. I copied\nthe working curl command and pasted it into the Curl-to-PHP website and\nit output some code. And it worked! Which I was very glad about because\nprevious research into how to make API calls with PHP was confusing to\nsay the least. Sometimes PHP gifts you with and abundance of riches\nwhich doesn't always make life easier.

                                                            \n

                                                            So I made my API call from my program. The Curl-to-PHP code returned\n$result. And then I used the json_decode command to turn the result\nstring into an array of Mastodon data.

                                                            \n

                                                            $obj = json_decode($result, true);

                                                            \n

                                                            And I could use the print_r command to look at that data.

                                                            \n

                                                            print_r($obj);

                                                            \n

                                                            I immediately put the print_r command at the bottom of my program\nwhere it resides today as commented out debug code. This way while I was\nlooking at my program output I could just scroll down or search to find\nwhat the actual data looked like.

                                                            \n

                                                            So I fumbled around for a while before I figured out that I would\nneed the id and the url to make my idea work.

                                                            \n

                                                            Accessing json data is reading an array. So easy peasy or maybe not.\nThis code returns the id of the reply from inside a while loop where $i\nis the index.

                                                            \n

                                                            $id = $obj['descendants'][$i]['id'];

                                                            \n

                                                            Like I said, it looks easy now. Needless to say it took some head\nscratching to figure out the exact syntax.

                                                            \n

                                                            I used to be a mason and people would always ask me how I learned\nmasonry. I'd look them in the eye and say, \"Trowel and error\". There\nwas, in fact, a lot of trowel and error going on.

                                                            \n

                                                            So then I generated the embed code to display each post and it\nworked. For all of my posts. Not for replies from other servers.

                                                            \n

                                                            So I scrolled down and examined the json data and I found the url\nfield that had all the info about the replies, server, username, and id.\nSo I picked up the url field the same way I picked up the id field and\nupdated my code with the url server and name.

                                                            \n

                                                            This still didn't work. After staring at the json data for a while\nthe light finally dawned. The id I was using was the gamerplus id from\nmy server. The id I needed to use was in the url field from their\nserver.

                                                            \n

                                                            Now that I had become enlightened it was easy to notice that the url\nfield contained the exact info that I needed to use in the embed.\nRemember what I said about doing it the hard way before you replaced\nthat code with the easy way. That can happen even when you have a\nplan.

                                                            \n

                                                            So by using the url data in the embed I have less string handling and\nfewer lines of code.

                                                            \n

                                                            I went to bed and in the morning I made this post.

                                                            \n

                                                            So the data structure I needed is called a multidimensional array or\nan array of arrays.

                                                            \n

                                                            In terms of a database table it is two columns and a bunch of\nrows.

                                                            \n

                                                            In terms of PHP arrays it's an array where each element is an array\nwith two values in it, the id and the url. Now, in my case, the id is\nfrom the gamerplus server. The url is from whatever server the replyer\ncalls home.

                                                            \n

                                                            I initialize the array with the parent post.

                                                            \n

                                                            $ids = array(array($id,$url));

                                                            \n

                                                            You can see the nested arrays in the code.

                                                            \n

                                                            Then I add items to the array like this.

                                                            \n

                                                            $ids[] = array($id,$url);

                                                            \n

                                                            I access an array item like this.

                                                            \n
                                                            foreach($ids as $id) {\n  $url = $id[1];
                                                            \n

                                                            The 1 refers to the second element of the array because programmers\nstart counting at 0.

                                                            \n

                                                            Then using the url and the domain that I captured from the GET\nparameter that passes the parent url into the program I build the iframe\nembed for that post using the Mastodon embed as a template.

                                                            \n

                                                            Which worked but the posts weren't displayed in chronological order.\nBecause the json data isn't necessarily in chronological order.

                                                            \n

                                                            So I had to sort the multidimensional array on the id. Which isn't as\nstraight forward as the sort() command.

                                                            \n

                                                            So I found this article on stackoverflow called

                                                            \n

                                                            How do I sort a multidimensional array by one of the fields of\nthe inner array in PHP?

                                                            \n

                                                            It had a two line solution that I modified to work with my array.

                                                            \n

                                                            And now all my posts were in chronological order.

                                                            \n

                                                            My first post quoted above was posted on Friday, October 25, at 8:40\nPM.

                                                            \n

                                                            On Monday, October 28 at 8:52 PM I wrote, \"Here's the blog post proof\nof concept/working code.\"

                                                            \n

                                                            Three days from \"I have an idea\" to \"working code\". That wasn't all I\ndid in those three days. Saturday I had a repertoire session with my\nband, Jazz Buskers. Sunday I produced my radio show, Something Blue. But\nwhen I'm in the middle of a programming project I get hyper focused.\nSometimes I have to force myself to step away.

                                                            \n

                                                            And I have worked on the code a little bit today. And I will in the\nfuture too. I did a lot of testing today and some Mastodon servers\nand/or accounts just don't support embeds. But if you want to use Embed\nMastodon Threads on your blog or website your toot will probably be the\nparent and if it works on your account, you're good.

                                                            \n

                                                            Also posts from different servers look different. Sometimes the\nbackground color is different. Sometimes the links look different.\nSometimes the whole post is a link to that post on Mastodon.

                                                            \n

                                                            I decided to embrace that as a feature rather than a bug with the\ndifferent look making it easier to distinguish posts made on Gamer+ from\nposts made on other servers.

                                                            \n

                                                            I have uploaded Embed Mastodon Threads to home.gamerplus.org. At my\nblog I have a post called Embed Mastodon Threads Hosted On Gamerplus\nwhere I say, \"The program is licensed GPL and I will put up a codeberg\nrepository so you can download it and install it wherever you want. But\nfeel free to use my server.\" And then I go into detail about just how to\ndo that in the embedded comments thread.

                                                            \n

                                                            The program is 46 lines of code with 11 lines of comments including\nattribution comments and debug code that is commented out. So 35 lines\nof code. Over three days that's 12 lines of code a day. About double\nnormal expectations for a programmer.

                                                            \n

                                                            This has been a long podcast, certainly longer than most of my\npodcasts will be. But I wrote it right after I did the project and it\ngave me an opportunity to discuss the development process. There were\nmany issues I had that I didn't mention but I think I hit the high\npoints.

                                                            \n

                                                            Throughout the whole project I was posting to my threads on Mastodon\nso that also helped me check back on the development history of this\nthree day project. The stream of boosts and replies from my compatriots\nhelped keep me going too.

                                                            \n

                                                            It was a rush!

                                                            \n

                                                            So this is not exactly a plain text program because it uses a\ndatabase accessed through the Mastodon API. Still, I do not have to\nmaintain that database, it's just there on every Mastodon instance,\nready to use.

                                                            \n

                                                            Most of my plain text programs are web apps or web pages. This one is\na web service.

                                                            \n

                                                            And it is simple to use. All you have to be able to do is copy the\nembed code from Mastodon, extract the link, and paste the link into the\nurl that calls the web service. Then you put that url into an iframe on\nyour blog or web page.

                                                            \n

                                                            I have a help page for using Embed Mastodon Threads in the same\ndirectory as the thread.php program where you can generate and copy your\niframe code. In fact the help page is also a Plain Text Program which I\nmay talk about in a future podcast. On the help page are instructions on\nhow to get a link from the Mastodon embed code. Then you paste the link\ninto a form and hit submit. The page generates your iframe embed code\nthat you can use in your blog or web page. The page also displays what\nthe embedded thread will look like.

                                                            \n

                                                            TuxJam co-host Kevie continues his series on Raspberry Pi projects with a look at the 3D RGB Xmas Tree from The Pi Hut. This is compatible with all of the Raspberry Pis,and, if you are going to use this as a stand alone Christmas decoration, it is recommended that you use RaspberryPi OS Lite.

                                                            Obviously there does need to be a bit of setup, it is not plug and play, but that would be boring for a Pi project; wouldn't it? As I said: I used mine with a Pi Zero 2W and if you are starting from scratch then I would recommend using Pi Imager as this will allow you to set a user, password, automatic login, wifi and SSH. Call it something like tree for the client name on the network so that it is easy to find. Doing all of this will mean that this Pi never needs to be connected to a monitor. The notes below should take you through the process step-by-step.

                                                            \n
                                                              \n\t
                                                            1. Once the tree has been installed and the Pi is booted up, install GPIOZero (this step is only necessary if you installed RaspberryPiOS Lite) sudo apt install python3-gpiozero
                                                              2. \n\t
                                                            2. Create a new directory: mkdir tree and move into it with cd tree
                                                              3. \n\t
                                                            3. Now it's time to get the code: wget https://tinyurl.com/3rrezjv9 -O tree.py
                                                              4. \n\t
                                                            4. I went for the Xmas Tree Sparkle sequence by Rendzina. To get this simply type: wget https://tinyurl.com/5e8cxrb5 -O XmasTree_Sparkle.py
                                                              5. \n\t
                                                            5. Test out the sequence: python XmasTree_Sparkle.py
                                                              6. \n\t
                                                            6. To automate the tree we can set a cron task: sudo crontab -e
                                                              7. \n\t
                                                            7. Add the following lines to the end of the Crontab file: 30 22 * * * /sbin/shutdown -h now This shuts it down at 10.30pm every night. @reboot python /home/pi/tree/XmasTree_Sparkle.py This will switch on the tree when the Pi boots up.
                                                              8. \n\t
                                                            8. Exit and save.
                                                              9. \n\t
                                                            9. Reboot the Pi: sudo reboot
                                                              10. \n
                                                            \n\n

                                                            \n Firstly, a little about why I have a complicated DHCP setup, and\n it starts with the router my previous ISP gave me.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n My router could just about cope with serving DHCP, but at the time\n when I was experimenting with running services on my home lab, the\n DNS server on the router wouldn't return addresses for hosts on my\n network, just those on the public internet. This wasn't a great\n experience! So, I installed PiHole [1] - initially because I'd\n heard good things about it's ad blocking capabilities, but later\n because it was just a pretty and sensible DHCP and DNS server that\n I could do things with.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Under the covers, PiHole is running DNSMasq [2], which means that\n all the configuration is plain text files that I can overwrite\n with Ansible [3].

                                                            \n

                                                            \n My PiHole was running on a Raspberry Pi 2 [4], in a lego-style\n case [5] plugged into the back of my router. And this was fine for\n a few months. And then it ran out of storage space, I changed\n jobs, my wife complained one too many times, and I reverted back\n to using the router's DHCPd and DNS. I also picked up either\n Nebula [6] or Tailscale [7] at around that time too, so I didn't\n need internal DNS to resolve to home services any more, and\n anything public I setup external DNS records pointing to the\n internal addresses. Job done.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Scrub forward a couple of years, and when I changed jobs, I got a\n joining bonus which paid for me to get wired network around my\n house. I also setup my own Proxmox [8] cluster, which I documented\n on a post [9] on my blog [10]. Again, everything was peachy. I\n setup home assistant [11], which I expose on to the internet via a\n proxy on my VPS, and everything was still good... but things are a\n little more complicated now - I've got more stuff to keep track of\n and the router's DHCP server was struggling a little... but it was\n all OK.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n And then I changed ISP. My new ISP shipped a router running a\n customized version of OpenWRT [12], and I thought, finally, a good\n router! And then I realised I couldn't do *anything* sensible with\n it. It was so locked down, I couldn't even change the admin\n password without factory resetting it! Ugh. Within a couple of\n weeks my wife was complaining about random intermittent DNS\n requests failing, and I was seeing it too. So, I found on the\n Proxmox Helper Scripts [13] website that someone had put a script\n to setup a PiHole instance... So naturally, as I had two Proxmox\n Servers by this point, I ran two PiHole servers. This lasted a few\n months until I performed a system upgrade to the proxmox cluster\n and it took down both Proxmox cluster members at the same time and\n DNS fell off the network! I revived the Raspberry Pi 2 which now\n sits attached to the router again! Yes!

                                                            \n Meanwhile, I was now getting more into IoT and I had several Tuya\n IoT devices connected over Wifi, and the 254 network addresses\n available in the /24 sized network [14] to me at home didn't seem\n enough, so I decided to expand my network to a /22, giving me\n enough address space for 1022 devices. Plus, I have kids, who each\n have computers and phones and games devices, my wife and I both\n work from home, so we both have computers from work and our own\n devices too... so I decided, now is the time to plan out my\n network.

                                                            \n I decided to use PHPIPAM [15] having been asked to look at it at\n work, and found it was a good fit for what I wanted to do with it.

                                                            \n PHPIPAM is really designed for owners of large-scale networks,\n people who allocate chunks of public IP scopes and IPv6 address\n ranges, but it will subdivide smaller network blocks, and so I\n could carve up my network.

                                                            \n

                                                            \n I decided to split my /22 into four /24 networks. One was\n dedicated to DHCP addressed items, with one smaller subnet in\n there allocated to the Proxmox hosted PiHole and another to the\n Raspberry Pi hosted PiHole, and both are basically a catch-all for\n anything I've not yet allocated. One was for end-user devices,\n like phones, computers, TVs and Games Consoles separated into\n smaller subnets per-person and one additional subnet for\n room-shared devices like TVs and Games Consoles. One subnet was\n separated into smaller subnets for IoT devices and core network\n things, like mains and network switches, light bulbs, cameras and\n printers. The last /24 subnet was undivided, but was for servers,\n both physical and virtual.

And, while I'd been using Gravity Sync [15] to\n synchronize between the two PiHole devices, sometimes it took a\n while for Gravity Sync to sync.

                                                            \n So, I turned to Ansible.

                                                            \n A few years ago, I'd helped write some Ansible modules which were\n used to interact with a cloud service my employer at the time was\n running, so I had a kind of idea on how Ansible works under the\n surface, the documentation for writing a new set of lookups was\n OK, and ChatGPT helped where I lost my way.

                                                            \n I knew that there was a Terraform [17] Provider [18] for PHPIPAM,\n so there was a working API... and so I knew I could look up data\n in PHPIPAM. I wrote some Ansible lookups [19] to confirm the data\n was accessible from PHPIPAM, and it was! Great, now all I needed\n to do was to drop files into PiHole.

                                                            \n I'd heard Alex [20] from the Self Hosting Podcast [21] talking\n about how he wrote some Ansible to automate his PiHole management\n [22], but it assumed a lot about how your network was setup and\n integrated a lot with other things he did - no complaints there!\n It's his network after all! But so I knew I needed to do 5 things.

                                                            \n I live in the eastern part of the state of Tennessee in the\n southeast United States. Our summers are fairly hot and humid, but\n our winters are generally mild. Last winter, we experienced an ice\n storm, with temperatures dropping into the single digits\n (Fahrenheit) or below -12 degrees Celsius. This was not a\n problem until tree limbs heavy with ice began to break off and\n fall, on occasion taking power lines with them. As a direct\n result, we lost power at my home. The icy road conditions\n made it difficult for service vehicles to reach impacted areas,\n and also made it impossible for us to leave our home.

                                                            \n My house is heated by a natural gas forced air\n furnace. However, the fan which blows hot air throughout the\n house, and the electronics which control everything from telling\n the furnace to turn on to igniting the gas, all require\n electricity. For anyone unfamiliar with how a forced air furnace\n works, I am including a link to a helpful YouTube video by The DIY\n HVAC Guy \n Link\n

                                                            \n So, with the loss of electrical power, came a loss of heat. We\n experienced a full day of being huddled under blankets and\n drinking warm beverages. These I could heat up on my gas\n stove, when I used a match or lighter to ignite the\n burner. Thankfully, the next day our power was restored, and\n our home warmed up again.

                                                            \n But that got me thinking, and searching for solutions. I\n needed to provide an alternative electrical power option for my\n gas furnace so that it would continue to work when the electricity\n was interrupted. I found a really interesting video, also by\n The DIY HVAC Guy (\n Link\n ), explaining an option for retrofitting the electrical\n connections to the furnace, but I never got around to doing\n it.

                                                            \n That changed, a couple months ago, when I found a real deal on a\n brand new portable solar generator. It is effectively a large\n lithium iron phosphate (LiFePO4) battery, an inverter, and a\n charging system, all bundled together in an easy to carry\n case. It provides over 1,000 watt hours of power. It can\n be charged using portable solar panels (which I purchased at the\n same time), or supported using external power sources from 12v to\n 48v DC.

                                                            \n The retrofit of the of the electrical feed line into my furnace\n was easily accomplished by doing something very similar to what\n was done in the video linked above. I turned off the circuit\n breaker for the furnace in the house's main electrical panel, and\n then located the switch box mounted on the side of my\n furnace. I removed the switch plate cover and tested the\n wires inside using a non-contact voltage tester, which would light\n up and scream at me if there was still any power to any of the\n wires. No screaming. No power. Good.

                                                            \n Next, I removed the switch from the box, disconnected the\n black power source \"hot\" wire from the switch. This would\n carry 120v AC directly to the switch and allow a user to turn\n the furnace on and off. The wires going into the furnace\n included a black \"hot\" wire, connected to the other side of the\n switch, and a white \"neutral\" wire which was connected using a\n wire nut to the white \"Neutral\" wire from the house wiring. I\n disconnected all of these wires, and also the ground wire from the\n house wiring.

                                                            \n I removed the front service panel from the furnace so that I could\n perform the next steps safely. I removed the \"single gang\"\n electrical box (which had housed the on/off switch) from the side\n of the furnace, where it had been attached using a single sheet\n metal screw. The term \"single gang\" describes a box which is\n only wide enough to accommodate a single standard sized switch or\n a single duplex outlet. A \"double gang\" box is wide enough\n for two such devices, and a \"triple gang\" is wide enough for\n three. Use the provided \n link for a more complete description of this naming.

                                                            \n I chose to replace the single gang box, which only held a switch,\n with a double gang box to accommodate both a switch and a\n duplex outlet. I could have used the existing box and used a\n single gang outlet/switch combination (Like the one at the\n provided \n link ), but I wanted to use a heavier duty switch and\n outlet.

                                                            \n I mounted a new double gang box to the side of the furnace using\n multiple sheet metal screws. Then I passed the Romex house\n wiring through a knockout hole in the side of the box and a\n protective wire clamp. I wired the black \"Hot\" wire from the\n house to the brass colored screw on a commercial grade 120v 15A\n duplex outlet. The neutral wire from the house went to the\n silver colored screw on the outlet, and the bare ground wire from\n the house connected to the green ground screw on the\n outlet. This was now connected just like any other outlet in\n the house, and controlled by the breaker in the house's main\n panel. I wrapped this duplex outlet with electrical tape, as\n I like to do any time I am working in a metal box or a box\n containing more than one device. Then I secured the duplex\n outlet to the box with included screws.

                                                            \n I knocked out another one of the side holes in the box, and\n installed another wire clamp, through which I passed some heavy\n duty 12ga (About 2mm conductor diameter) 3 conductor flexible\n cable. The black wire from this went to one screw connector\n on the switch, and the black wire from the furnace connected to\n the other screw connector on the switch. I connected the\n white wires (from the flexible cable and from the furnace)\n together using a wire nut, and connected the ground wire from the\n flexible cable to the green screw on the box.

                                                            \n The final installation steps were to connect a quality, 120v 15A\n plug to the other end of the flexible cable.

                                                            \n Now for the first test. I turned the breaker back on, and\n used an outlet tester to verify the newly installed outlet on the\n side of the furnace was working and wired correctly. I use\n one which displays voltage along with any wiring faults, and which\n also has a button which can be used to test ground fault circuit\n interrupts (GFCI) like the one found at the provided \n link .

                                                            \n Everything checked out properly, so I plugged the furnace into the\n outlet, using the flexible cord. Nothing happened, so I\n flipped the switch to the \"On Position\". I immediately\n saw blinking lights on the furnace controller board. Next, I\n adjusted the thermostat for heat, and within a minute, the furnace\n had ignited the burners and was blowing hot air.

                                                            \n Good. All my connections were verified, so I turned off the\n furnace, unplugged it, and installed the faceplate on the\n box. Yes, I know I could have done this before I plugged\n in the furnace. However, with over 40 years of experience\n building, repairing, and modifying electrical and electronic\n devices. I have learned to never put back together more than\n you must for a specific test. Otherwise, you will just need\n to go back and take it apart again when your test\n fails.

                                                            \n What was next? More testing, of course. I needed to\n figure out how much power the furnace used when generating\n heat. Because of the way the furnace was now wired, it was\n simple to connect an inline power meter between the outlet and the\n furnace plug. I plugged one in and turned everything back on\n again. The measured peak power use was 375 watts. The\n solar generator can easily handle this for a couple hours and I\n can charge it from various sources during gaps in operation.

                                                            \n So, I connected the solar generator and... Nothing. The\n furnace would not even complete its self-test\n sequence. Great... Did I break something? I plugged the\n furnace back in directly to the power outlet, and everything\n worked properly. Well, that's a plus, at least.

                                                            \n So, I spent the next several hours troubleshooting two different\n blinking light error codes on the furnace controller board. One\n referenced \"Hot & Neutral Reversed\" while the other referenced\n \"Open Ground\". That was odd. Well, I had never actually\n tested the output of this brand new solar generator, so I plugged\n my outlet tester into the solar generator, and it verified \"Open\n Ground\". Time for a technical support call.

                                                            \n You can purchase a Generator Bonding Plug, also called a\n Ground-Neutral Shunt, and I have included several links as\n reference. ( \n Bonding Plug or \n Ground Neutral Shunt\n  ). I found them selling for anywhere between $10 - $35\n USD. But all they are is a $1 - $2 USD plug with a wire\n connecting the ground terminal to the neutral terminal. So,\n naturally, I built one using a spare plug I had. I connected\n it to the solar generator, and the outlet tester was very\n happy.

The two things that we will need to set this up are the audio stream url and the time of the show.

                                                            To set this up we need to go setup a new Cron task: crontab -e and navigate to the bottom of the file.

                                                            Then we need to enter ffmpeg -i followed by the stream URL.

                                                            It is important that we include the duration of the recording, so that this doesn't output a huge file. To set the time enter -t HH:MM:SS making sure to replace the HH(hours) MM(minutes) and SS(seconds) with numbers.

                                                            \n\n

                                                            Almost done. The last thing we need to do is to enter the location for the file to go along with the name /path/filename.ogg.

                                                            \n\n

                                                            So in short form the command is * * * * * ffmpeg -i https://streamurl -t HH:MM:SS /path/filename.ogg.

                                                            The first was episode 4258 where I gave my introduction and computer history.

                                                            Once again I am recording the audio on my Samsung Galaxy S21 Ultra phone, running Android 14, with Audio Recorder by Axet. The app was installed from F-Droid.

                                                            He said he wanted to hear more, and highly suggested that I record the story as an HPR show, so here we are.

                                                            \n

                                                            I plan to ask the questions I hear from so many, and attempt to answer them as best I am able.

                                                            What is the History of God's Pantry Food Bank?

                                                            Mim Hunt, the founder of God's Pantry Food Bank, vowed to leave \"the heartbreaking profession of social work\" behind when she returned to her hometown of Lexington after serving as a child welfare worker in 1940's New York City. She and her husband, Robert, opened \"Mim's,\" a combination gift shop, antique gallery, and health food store, but after seeing poverty in Lexington that rivaled what she'd fought against in New York, she found herself unable to remain silent.

                                                            \n

                                                            Mim began her work in Lexington by filling her station wagon with food, clothing, and bedding, and distributing it directly to individuals in need.

                                                            Soon, neighbors were bringing food donations to what became known as \"Mim's Pantry\" located at her home on Lexington's Parkers Mill Road. But Mim quickly corrected them. \"I don't fill these shelves,\" she said. \"God does. This is God's Pantry.\" God's Pantry Food Bank was born out of this work in 1955 and remained mobile until the first pantry was opened in 1959.

                                                            \n

                                                            Since its founding, the food bank has grown in many ways. What started with one woman attempting to do what she could to address a need is now an organization serving 50 counties in Central and Eastern Kentucky through a number of programs with a dedicated staff committed to the mission of solving hunger.

                                                            Mim Hunt devoted her life to helping others, and we continue to honor her legacy at God's Pantry Food Bank. Her work is proof that one person, with every small action, can make a large impact. We invite you to join us in continuing Mim's work.

                                                            \n

                                                            In February 2023 I wrote a blog post with my explanation of Food Bank. My website is LinuxSpider.net, and you will find the direct link in the shownotes.

                                                            \n

                                                            The blog was written as a response to friends, mostly from the United Kingdom, asking me very this question.

                                                            \n

                                                            To many there, and indeed here in USA also, what is called a Food Bank is what I call a local Food Pantry. Nobody is wrong here at all. We all gather food from various sources and distribute it to our neighbours who are in food insecure need.

                                                            \n

                                                            Most Pantries are totally staffed by volunteers and often open limited hours.

                                                            The Food Bank has a larger scope in where we source food from, the amount sourced, does have paid staff but still dependent on volunteers, and we are open at least 40 hours a week. More if you include projects that involve evenings and Saturdays.

                                                            How did I get started at the Food Bank?

                                                            \n

                                                            As mentioned in my introduction show I moved from Scotland to Kentucky in May 1999 and married Arianna in June 1999.

                                                            \n

                                                            Before our wedding I had received my green card. My future Mother-in-Law Eva recommended I check with God's Pantry Food Bank to see if they were hiring.

                                                            \n

                                                            She was working for Big Lots and had applied for a warehouse job at the Food Bank. Unfortunately for her she never got the job, but she was quite impressed by the organisation. She knew that I had warehouse and driving experience.

                                                            \n

                                                            So, one day after dropping Arianna at her University of Kentucky Medical Staff Office I stopped by the Food Bank on South Forbes Road to ask.

                                                            \n

                                                            The answer was that they were indeed hiring for the warehouse, and to come back that afternoon to meet with CW Drury, the Warehouse Manager. I drove home, put on smarter clothes, and drove back.

                                                            \n

                                                            It was a pleasure meeting CW and hearing about the job. Although most of the explanation of what they did in their mission went over my head at the time, I knew needed a job, and wanted to join this company.

                                                            \n

                                                            A few days before our wedding I received a phone call from CW offering me the position. I accepted and went for my medical the next day.

                                                            \n

                                                            My first day with God's Pantry Food Bank was on Tuesday 6th July 1999, the day after our honeymoon.

                                                            \n

                                                            I will admit that although my previous job in Scotland was a physical one, quite a few months had passed, and the heat was hot that Summer in Kentucky! I went home exhausted everyday, but totally enjoying the work I was doing.

                                                            \n

                                                            I started off mostly picking orders, assisting Agencies that came in, going to the local Kroger supermarkets to pick up bread, deliver and pick up food barrels of donations, and all the other duties CW assigned me to.

                                                            \n

                                                            I particularly enjoyed the software part of the job. I forget the name of the software back then, but do remember learning the 10 digit Item Codes.

                                                            \n

                                                            \n

                                                            The first code I memorised was Bread Products: 1040010731

                                                            \n

                                                            This broke down to Donated, Bread Category, UPC number, and Dry Storage.

                                                            \n

                                                            I must admit we did not create a new code when we started storing Bread Product in the Cooler. That is probably the only exception

                                                            \n

                                                            It has been my responsibility all these years to maintain the Item Category Code sheet with different codings we have used and had to invent.

                                                            \n

                                                            An example is that when the source digit had already used 1 to 9, we had to start using letters. Although there were concerns at the time, everything worked out well.

                                                            \n

                                                            When I started at South Forbes Road there were 11 employees there and Debbie in Prestonsburg. 12 in total, in 2 locations.

                                                            \n

                                                            These days we have over 80 employees in 5 locations: Lexington, Prestonsburg, London, Morehead, and a Volunteer Center on Winchester Road, Lexington, near the Smuckers JIF Peanut Butter plant.

                                                            \n

                                                            My time at 104 South Forbes Road was for a full 4 weeks!

                                                            \n

                                                            In August 1999 we moved to 1685 Jaggie Fox Way, into a customised warehouse with 3 pallet tall racking, and lots of office space. It felt so large back then!

                                                            \n

                                                            On my first couple of days of unloading trucks there I totally wore out a pair of trainers!!

                                                            \n

                                                            Jaggie Fox does sound like a strange name for a street, but I later learned it came from 2 ladies, Mrs Jaggie and Mrs Fox who owned the land before the business park purchase. Anyway, that's what I have been told by mulitple people.

                                                            \n

                                                            Technology was fun in 1999, as we had a 56K phone modem, about 10 computers, and 1 printer. You can imagine the shared internet speed.

                                                            \n

                                                            I forget how long, but we eventually got DSL, then Cable.

                                                            \n

                                                            What have been my duties at the Food Bank?

                                                            \n

                                                            For my first decade of employment I worked the warehouse and as a driver.

                                                            \n

                                                            This included delivering food to the 4 to 5 local pantries that we ran ourselves in local church buildings in Fayette County.

                                                            \n

                                                            Funny story is that a couple of years into the job, I was approached by the Development Manager and asked if I knew websites and HTML. I informed her that I was familiar, and she made me responsible for the maintenance of the website that University of Kentucky students had created. It indeed was quite basic with only HTML and images.

                                                            \n

                                                            I had this duty for a few years before a professional company was hired.

                                                            \n

                                                            I mentioned Inventory software. In early 2000 we moved to an ERP, that is an Enterprise Resource Planning suite named Navision written by a Danish company. That company was then taken over by Microsoft. For as while it was called Microsoft NAV, and these days it is part of Dynamics 365.

                                                            \n

                                                            Feeding America commissioned a module named CERES which assisted us non-profits to use profit orientated software. Inhouse, we just call the software CERES.

                                                            \n

                                                            Even though I was no longer maintaining the website, I was still involved in IT to a degree. I became the inhouse guy who would set up new employees with their own computer. Ah, the days of Active Directory. I never did like it!

                                                            \n

                                                            I was also the guy the staff came to first with their computer problems. Funny how a lot of these issues were fixed when I walked in their office. If I could not fix an issue there and then, we did have a contract company on-call.

                                                            \n

                                                            They maintained our server and other high level software.

                                                            \n

                                                            This was still when I was in the warehouse role.

                                                            \n

                                                            After that first decade I was allocated to be our Welcome Center person, which I did for 3 years.

                                                            \n

                                                            This involved welcoming agencies, guests, salespersons, volunteers, and assisting other staff members in many ways.

                                                            \n

                                                            I also went from being a driver to the person who handed out delivery and pick-up routes to the drivers.

                                                            \n

                                                            During these years I became a heavy user of CERES working with the agencies and printing out pick-sheets to our warehouse picking staff.

                                                            \n

                                                            Although I really enjoyed the work, I will openly admit that I am not always the best in heavily social situations. I did have some difficulty when the Welcome Center was full of people needing my attention and I was trying to get software and paperwork duties done. Somehow I survived!

                                                            \n

                                                            My next stage of employment was moving into the offices and becoming the assistant to the Operations Director.

                                                            \n

                                                            This is when I really took on the role of food purchaser, ordering fresh produce and food from vendors as part of our budget.

                                                            \n

                                                            I also took over the responsibility of bidding for food donations from the Feeding America portal named Choice. National Donors offer truckloads of food and other items to the network, and we Food Banks bid on them in an allocated share system. The donations are free, but we pay for the truck freight from the shipping locations.

                                                            \n

                                                            A full time IT person was hired. We are now on our 4th IT Manager. The last 2 each had assistants.

                                                            Although I am grandfathered in as an admin, my duties in this regard are very low, but still have the abity to install software as needed. Quite handy on my own laptop.

                                                            \n

                                                            As well as being the Food Procurement Officer I also became the Reporting Officer.

                                                            \n

                                                            This has been greatly aided by our team receiving the ability to write our own reports from the Navision SQL database using Jet Reporting.

                                                            \n

                                                            This is an Excel extension that allows us to access field data not directly obtainable in the CERES program.

                                                            \n

                                                            The fore-mentioned Robert Srodulski used to spend a day creating a monthly report that included all of our 50 counties across multiple categories of data. He would step by step complete an Excel worksheet with all this information.

                                                            \n

                                                            I took his spreadsheet, converted it into a Jet Report, and it now runs in about 5 minutes!

                                                            \n

                                                            It is my responsibility to supply reports on a regular monthly, quarterly, and yearly basis to my Directors, fellow staff, and to Feeding America.

                                                            \n

                                                            Yes, I do have an orange mug on my desk that says "I submitted my MPR". That is the Monthly Pulse Report. It sits next to my red swingline stapler!

                                                            \n

                                                            What are God's Pantry Food Bank's sources of food?

                                                            \n

                                                            This is probably the question I get asked the most when friends and online contacts find out what I do for a career.

                                                            \n

                                                            We receive and obtain food from various sources, including:

                                                              \n

                                                            • Local donations from people like you. Thank you!

                                                            • Local farmers.

                                                            • Local retail companies and other businesses giving food directly to us and to our Partner Agencies. We are the official food charity of many retailers, including Walmart and Kroger.

                                                            • National Companies, mostly through the Feeding America Choice Program.

                                                              \n

                                                            • The USDA, U.S. Department of Agriculture, supplies us with multiple programs of food: TEFAP (the Emergency Food Assistance Program), CCC (Commodity Credit Corporation), and CSFP (Commodity Supplemental Food Program).

                                                              \n

                                                            • Purchased food, including Fresh Produce, via donations and grants.

                                                              \n

                                                            \n

                                                            Without all this food coming in, we would not be able to distribute to our internal programs or to our partner agencies, allowing them to run Backpacks for Kids, Food Boxes for Seniors, Food Pantries, Mobile Distributions, Sharing Thanksgiving, and a multitude of other services we offer our neighbours.

                                                            \n

                                                            We have a team of Food Sourcers that work directly with the retail companies, so I am not fully involved there, but I am the main Food Purchaser for the majority of the food we buy. Specialised internal programs like Backpack and local Pantries do order specific foods that they need on a regular basis. I try to supply for the long term.

                                                            \n

                                                            With the USDA CSFP program I am responsible for the ordering of that food through a Government website. Often 6 to 12 months ahead of time.

                                                            \n

                                                            Here's a truth that staggers many people when I inform them:

                                                            \n

                                                            If you are spending cash on food donations to God's Pantry Food Bank, the most efficient use of those funds is to donate it to us.

                                                            \n

                                                            I truly can obtain about $10 worth of food for every $1 given.

                                                            \n

                                                            An example is that I recently obtained a full truckload donation of 40,000lb of Canned Sliced Beets (yum!) that we are paying only freight on.

                                                            \n

                                                            Do the maths.

                                                            I personally waited until the very last day, Friday 13th of December, to move out of my Jaggie Fox office and into my new one at Innovation. Our official first day was on Monday 16th December 2024.

                                                            \n

                                                            What I tooted and posted on that Friday caught the eye of my CEO, Michael Halligan, and he asked me if he could share it with others. Of course he should!

                                                            In the Shownotes I have included a link to my Mastodon toot. It's too long a number to read out.

                                                            I am absolutely loving our new location.

                                                            It's my challenge to fill the cooler, freezer, and dry warehouse with donated food!

                                                            \n

                                                            My new office is 97% set up to my workflow, including my infamous hanging report boards, and spiders everywhere.

                                                            All that said, it truly is the only job I have ever had which I absolutely enjoy, but totally wish did not exist!!

                                                            What happens if one sine wave is modulated with another sine wave?\nSimilar to sending a pure tone over AM radio.

                                                            \n

                                                            Apparently the result is two frequencies, one equal to the difference\nof the two original frequencies and one equal to the sum.

                                                            The original tones were 1 kHz and 0.5 kHz.

                                                            \n

                                                            The result was a peak at 0.5 kHz (the difference) and one at 1.5 kHz\n(the sum).

                                                            On another note, the manual mentions in practice if one of the tones\nis the carrier frequency and one of them is the signal, then the carrier\nshould not be modulated all the way down to zero or all the way up to\nmaximum. This avoids distortion and clipping so the quality is better\nwhen received. It is also more power efficient so the transmission can\ntravel further given the transmitter has a limited power output.

                                                            \nThe Wayback Machine by The Internet Archive is a very good resource for web sites no longer existing or older revisions of them.

I have also used it for fact based sites which I want to always have access to, like a reference book. One of my recent use cases was a magazine that has closed down and announced the web site will also soon be terminated. Although it is available in the Wayback machine, I wanted to have a copy myself for a short period of time.

                                                            \nThe software I use for this HTTrack. This software is available for Windows, Android, Linux and unix-like systems. It is at least for some platforms available with a graphical user interface. I have myself only used HTTrack with the terminal interface on Linux. HTTrack is a free and open source software.

                                                            \nIn its simplest way to operate, it is just to type \"httrack\" followed by the url to the start page of the site to be copied.

                                                            \n

                                                            \nIn many cases this works well, I get a perfect copy. In other cases, it works less well. First of all, of course, I do not copy very big websites, both for the amount of time it takes and the disc space. What is stated in the robot textfile can also matter for the result. Another issue can be the folder structure of the site, HTTrack may not find all folders in its default setup, for example how images are stored. I have myself also got issues when menues and links not works normally where I instead have to right click to open the link.

                                                            \n

                                                            \n

                                                            \nThe HTTrack web site has quite a lot of information in the documentation and it also has a forum. And in the terminal, there is also good help about all additional available commands. I have in general for my usage found the simple first attempt to copy sites gives perfect or good enough result directly without need to research details.

                                                            \n

                                                            \n

                                                            \n

                                                            \nSo, when I want to preserve snapshot of earlier releases of my own sites or when I want to have an offline and preserved copy of an important site, I consider HTTrack to be an easy to use and yet powerful tool. I am aware other similar tools exist, but this is the one I currently use.

A quick work around for this was to put it in a url shortener, for this example I'm using \nTinyURL\n.

                                                            \nAnother issue arose when the stream recorded without first removing the audio file, I could see this being an issue when you want to record a show when you will be away over multiple weeks. To overcome this we simply edit the Crontab file (command \ncrontab -e\n) and add the following to the end of the file, before the extension: \n$(date +\"%Y_%m_%d\")\n

                                                            \n

                                                            \n\nThe first half of the book is to build a tree-walking interpreter in Java.  The 2nd half of the book is to build a bytecode compiler in C.  Both of them are for a programming language the author called lox. L-O-X.\n

                                                            \n\nThe book is smart because it is based on generic Java and C code, and does not specify any IDE or make file to use.  You will have to figure out that yourself.  That may sound like a hurdle but in fact it is a blessing.  That makes the code in the book very portable.\n

                                                            \nI am so looking forward to the new Superman movie by DC, with\nJames Gunn as showrunner. In that film the actor Nathan Fillion\nplays a Green Lantern named Guy Gardner.

                                                            \n

                                                            \nRecently I remembered that I owned a Green Lantern Blu-ray\nanimated movie with Nathan Fillion as the voice of Hal Jordan.\nThat movie is named Emerald Knights.

                                                            \nThese days when I purchase a Blu-ray it normally comes with a\ndigital code for \nMovies Anywhere\n. Therefore I often never play the physical disk at all. This\nparticular disk did not have that option.

                                                            \n

                                                            \n

                                                            \nI searched the streaming services for where to watch Green\nLantern: Emerald Knights. Seems it is only available for rent or\npurchase. Obviously since I own the disk I am not going to do\nthat.

                                                            \n

                                                            \nTherefore, I tried once again to try to play the disk directly on\nmy Linux system.

                                                            \nWe do have dedicated Blu-ray players in the house. One is a\nSamsung unit in our living room, but that is where my\nDragon-in-Law Eva lives. The other is a Playstation 3 in our\nbedroom. There is also the factor that I wanted to watch while\ndoing other computer projects in my own room.

Many use this program\nto copy their Blu-Rays to a storage medium for their own\nhome-streaming purposes. I have yet to go down that road, as I\njust wanted to play the disk. Plus I don't have that much storage.

                                                            \n

                                                            \n- Create a user, add it to the sudo group, with password \"\" and /bin/bash for shell

                                                            \n

                                                            \n- Create a .ssh for your user, and echo in your SSH public keyboard

                                                            \nBy doing -p \"\" we set the password to empty.

                                                            \n

                                                            \nIf we had not done -p \"\" the password would have been empty but locked, so you wouldn't be able to sudo.

                                                            \n

                                                            \nAlso go ahead and lock your root user password, which you could also do from the file.

                                                            1. You can't use the first and the last IP address in a /24\n block.

I have filled it with all of the cables,\n chargers, headphones, etc. that I might need when on the road. Now\n when I am packing I don't have to run around looking for cables, I\n only need to throw this pouch into my bag and I am ready to go.\n This is a real time saver, and I always have what I need.

                                                            \n The Indie Archive is a archival solution for indie producers.\n Since most indie producers run on a shoestring budget it's\n important that the Indie Archive is inexpensive to install and\n run. It's especially important that monthly expenses are minimal\n because a reasonable expense most months will sometimes be more\n than an indie producer can afford during some months.

                                                            \n Indie Archive is an archival system which is different than a\n backup system. If you don't have a backup system do that first. My\n backup system uses the same tools as Indie Archive, rsync and\n rsnapshot. My brother uses the online backup service Carbonite.\n There are many other options.

                                                            \n A good backup system runs automatically to back up everything\n frequently and preserve version history. It's also good to have\n backups offsite.

                                                            \n An archival system, like Indie Archive, keeps multiple redundant\n copies across several hard drives on several systems in multiple\n locations. An archival system also checks file integrity as\n protection against file corruption or user error.

                                                            \n

                                                            \n

                                                            \n When you have a project you really never want to lose, like a\n finished novel, a music album, a video, or any other major effort\n that involves significant work, that's when you need an archival\n system.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n So The Indie Archive does not automatically backup your projects\n every day. That's what your backup system should do.

                                                            \n The Indie Archive is an archival system where the producer of the\n content decides what needs to be archived and when it needs to be\n archived and then manually moves a directory containing the files\n onto the Indie Archive carefully preserving the file's metadata\n during the transfer. Then these files are propagated over at least\n 7 hard drives on 4 different systems in three locations.

                                                            \n File integrity checks are run daily comparing the files and\n reporting discrepancies.

                                                            \n Two of the systems are kept in the studio where the content is\n produced. I call them the primary and secondary systems. They have\n a boot drive and two data drives each.

                                                            \n One of the systems is kept offsite at a nearby location. I call it\n the remote system. It also has a boot drive and two data drives.\n If you have a more distant location where you can put a second\n remotes system you can have remotenear and remotefar systems.\n Otherwise ...

                                                            \n The final system is somewhere in the cloud provided by a\n professional data storage provider. It has a single copy of the\n data and usually some additional data retention. The provider\n makes the backups of this data. This is the part that might\n involve a monthly bill. So, depending on the size of your file\n set, it could be free or it could cost so much a month. There are\n a lot of options for cloud storage providers.

                                                            \n As far as the hardware goes the systems are the same. Now, I\"m a\n Linix guy and I do all my production work on Linux so I'm using\n Linux. I want to test the system on several versions of Linux and\n with BSD.

                                                            \n I'm not a Mac guy or a Windows guy so I won't be going there. The\n software is open source and the required programs run on all three\n platforms so I'll let a Mac or Windows programmer test The Indie\n Archive for their systems. My guess is that the Mac fork will be\n easier than the Windows fork because of the file metadata. It\n might even be possible to add Mac folders to The Indie Archive\n running Linux but I'll let someone who actually has a Mac figure\n that out.

                                                            \n I don't think the same is true for Windows. Windows file metadata\n is different and so if you want to preserve the metadata you will\n probably have to install The Indie Archive on Windows systems.

                                                            \n So, I'm developing and deploying on Linux and I will also test on\n BSD. So far I have tested Debian, Ununtu, FreeBSD, Midnight BSD,\n and Xubuntu and The Indie Archive works fine all of these\n operating systems.

                                                            \n So, back to the hardware. Pretty much any older system that will\n support at least three sata drives will work. I'm using older\n business class desktops, Dell and HP. I pulled mine out of storage\n but they are very inexpensive to buy if you're not like me with a\n shed full of old computer stuff. I just bought a Small Form Factor\n HP Desktop on ebay for $30 including tax and shipping.

                                                            \n To clarify, it's best if the primary system supports 4 sata\n drives. The secondary and remote systems do not need an optical\n drive so they should support three sata drives but they can be run\n on two sata drives if you boot from the primaryfile drive. I am\n currently testing a remote system with two sata drives running\n Midnight BSD.

                                                            \n There are three drives on each system, a boot drive and two data\n drives. The boot drives can be SSD or spinning hard drives and\n need to be big enough to hold the OS comfortably. The data drives\n need to be large enough to hold the files you want to archive and\n they should be high quality spinning drives, I use the multi\n terrabyte HGST drives and I am also looking at some Dell drives\n made by HGST.

                                                            \n

                                                            \n

                                                            \n There will be a data drive and a snapshot drive on each system. If\n they are not the same size the snapshot drives should be larger. I\n am testing with 3 terrabyte data drives and 4 terrabyte snapshot\n drives. Besides the main data set that is being archived the\n snapshot drives also hold the version history of files that have\n been deleted or changed. So, that's why they should be the larger\n drive.

                                                            \n

                                                            \n

                                                            \n

                                                            \n So my primary system has a primaryfiles directory with a 3\n terrabyte drive mounted to it and a primarysnapshots directory\n with a 4 terrabyte drive mounted to it. Same for the secondary and\n remote systems.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Now, so far I only had to buy one drive but generally speaking the\n six data drives will be the major expense in assembling the\n systems.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n So a good bargain on six 4 terrabyte drives could be $120 used or\n $270 new. And this is the most expensive part.

                                                            \n I install used HGST drives all the time and rarely have problems\n with them. I have worked for clients who won't buy used, only new.\n Since the file integrity checks should give early warning on a\n drive failure and since there is a seven drive redundancy on the\n data files, if I were buying drives for The Indie Archive I'd go\n with six used 4 terrabyte HGST drives for $120.

                                                            \n There is no reason not to use drives all the same size as long as\n the snapshot drives are large enough. The size of data drives you\n need depends on the size of your projects and the time it takes to\n do a project. Look at your hard drives on your working systems.\n Think about what directories you would like to see in archival\n storage. What is the total size of these directories? Check how\n many gigabytes these projects have consumed in the last year.\n Think forward a few years. Assume you will use more disc space in\n the future than you are now. Do some quick arithmetic and make a\n decision.

If I had to buy\n drives I probably would have tried to start larger. I am sure that\n at some point in the not to distant future, when I am running The\n Indie Archive and not developing it, I will have to upgrade my\n drives.

                                                            \n I know that there are network options available but I am hesitant\n to recommend them because if I can transfer files from a system to\n the primary sytem over the LAN than anyone can do the same. Or\n delete files. Or accidentally delete directories. I kind of want\n to keep tight control over access to the primary system. It kind\n of ruins the archival quality of The Indie Archive if anyone on\n the LAN can accidentally mess with it.

                                                            \n

                                                            \n So, I am open to dialogue on these issues. I'm kind of where I\n want it to be easy to add projects to The Indie Archive but not\n too easy, if you know what I mean. I feel like having to sit down\n at the primary system and enter a password should be the minimum\n amount of security required to access the primary system.

                                                            \n The primary system also runs file integrity checks daily from a\n cron job. All of the propagation and file integrity scripts have\n to be run as root to preserve the metadata since only root can\n write a file that it doesn't own.

                                                            \n

                                                            \n The secondary system is the ssh server for The Indie Archive. The\n primary system logs onto the secondary system as root using ssh.\n Security is managed with public and private keys so entering a\n password is not required. After the keys are set up for both the\n primary and remote systems, password authentication is disabled\n for the ssh server so only those two systems can ssh into the\n secondary system.

                                                            \n

                                                            \n

                                                            \n When the propagation script is run on the primary system rsnapshot\n is used to create a current version of the primaryfiles directory\n in the primarysnapshots directory.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Then the primary system uses rsync over ssh to make a copy of the\n primaryfiles directory to the secondaryfiles directory.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Then the primary system logs onto the secondary system as root and\n rsnapshot is used to create a current version of the\n secondaryfiles directory on the secondarysnapshots directory.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Finally, if cloud storage is being used, the primary system uses\n gcloud rsync to make a copy of the primaryfiles directory to a\n google cloud storage bucket archive. I have this bucket set to 90\n days soft delete. If you are using another type of cloud storage\n on Google, AWS, Mega, or other storage providers this command will\n have to be adjusted.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n The reason I chose the gcloud archive bucket is because of the\n storage cost per gigabyte. They have the cheapest cost per\n gigabyte that I found. This will keep the monthly bill low.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Once a day the primary system runs the file integrity check from a\n cron job using rsync to compare the primaryfiles directory to the\n current version, alpha.0, in the primarysnapshots directory\n logging any discrepancies. It then does the same comparing\n primaryfiles to secondaryfiles and to the current version in the\n secondarysnapshots directory, logging discrepancies and notifying\n the maintainer of any discrepancies. Notification is done by email\n using curl and an SMTP provider.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n The remote system runs on it's own schedule, logging into the\n secondary system daily to copy data from secondaryfiles to\n remotefiles and then using rsnapshot to make a copy of remotefiles\n to the remotesnapshots directory.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Since it's run on a daily schedule it uses rsnapshot with the\n standard daily, weekly, monthly, and yearly backups.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n The remote system also runs a daily file integrity check comparing\n remotefiles to the current version on remotesnapshots and\n comparing remotefiles to both data directories on the secondary\n system, again logging the results and notifying the maintainer of\n any discrepancies.

                                                            \n

                                                            \n

                                                            \n If there is an outward facing static IP at the location with the\n primary and secondary systems then the remote system can use that\n static IP to ssh into the secondary system. If there is not a\n static IP then the remote system uses a DuckDNS subdomain to log\n onto the secondary system. Any system using the same router as the\n secondary system can run a cron job to update DuckDNS with the\n current IP address.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n Since a static IP is a monthly expense it's important that there's\n an alternative that does not require paying another bill.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n So the secondary system has the ssh server but it doesn't really\n do much. Both of the other systems connect to it and use it as the\n junction for data propagation and file integrity checks.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \n So, as you can tell, there's a lot going on to make The Indie\n Archive work. Future podcasts will get down into the details and\n discuss some of the choices I had to make and why I made them.

                                                            \n

                                                            \n

                                                            \n

                                                            \n The funny thing about this project is that the actual code was the\n least amount of work. Figuring out exactly how rsync and rsnapshot\n work together was quite a bit of work. Configuration for both\n rsnapshot and ssh took a bit of head scratching. Then there were a\n few user id tricks I had to work through to make The Indie Archive\n usable. But, by far the most work was writing The Indie Archive\n installation document detailing each step of installing the\n software on three systems.

                                                            \n It's been fun so far. If you have input I always appreciate the\n help. I get quite a bit of help on Mastodon.

                                                            I never was attached to history (I’m a\n shame with events, names, dates ), much less of history\n fictionalized, like historical romances. But I\n ended up working on a piece of it. The event passes between 1931\n and 1945. It relates to WWII — it’s part of it.

                                                            \n

                                                            So , I talk about producing an specific\n audiod rama, covering two points, that are at really three:

                                                            \n
                                                              \n
                                                            • WHAT is the story: the chaos that came to me asking to come\n out; and
                                                              • \n
                                                            • WHY I decided to present it (and HOW:) by a podcast of\n fiction with history.
                                                              • \n
                                                            \n

                                                            In the end , I summarize that I got touched\n by the subject, it impacted me with disastrous images both in\n words and images. And I like audio, well-made audio content. In\n synthesis, the real story touched me and urged the crave of\n creating something from it, resulting in an audio drama. A minute\n of it translated on the end.

                                                            \n

                                                            First, the WHAT. In the wanderings of the World Wide Web, a\n notable event was revealed before my eyes, a war scene that was\n under dust for decades, but people, even participants of it in\n varied degrees, came to reveal the fact; so, today, we know it.

                                                            \n

                                                            China and Japan engaged in war by the year 1931. More exactly,\n that is when Japan started colonizing China by the provinces\n of Manchuria, northeastern of the country.

                                                            \n

                                                            The resistence started in 1937, with reaction by the Chinese\n troops. Japan was so much more powerful, though (and that’s why\n China took so long to decide fighting the Imperial Army of Japan).\n It took time, and without the best outcome, but it demanded\n courage, it showed force, and humanity, moral value. And this\n conflict is part of the second World War, that\n by one side had Japan, Italy\n and Germany (the German Reich), heading the Axis\n powers; who were fought against by the Allied powers,\n headed by the Soviet Union, Great Britain, France, United States\n and China.

                                                            \n

                                                            Even with basically all the rest of the world against the Axis,\n the Japanese occupied the 3 provinces of Manchuria from 1932 until\n the end of the war, in September 2, 1945, making of it the main\n territorial base for development of weapons. The Encyclopedia\n Britannica explains us the following, quote:

                                                            \n

                                                            On March 9, 1932, the Japanese created the puppet state\n of Manchukuo […] out of the three historical Manchurian\n provinces. The last Qing (Manchu) emperor, Puyi, was brought\n to Manchuria from his retirement in Tianjin and made “chief\n executive,” and later emperor, of the new state. The Manchukuo\n government, though nominally in Chinese hands, was in fact rigidly\n controlled and supervised by the Japanese, who proceeded to\n transform Manchuria into an industrial and military base for\n Japan’s expansion into Asia. The Japanese took over the\n direction, financing, and development of all the important\n Manchurian industries, with the fortunate result that by the end\n of World War II Manchuria was the most industrialized\n region in China.

                                                            Now, very briefly, we come to the Unit 731. It was a big Japanese\n construction first officially designated as a “Epidemic Prevention\n and Water Supply Department”. It was commanded by the\n tenant-general of the Army and microbiologist Shirō Ishii.

                                                            I wanted until now to say what is the theme before hopping to the\n motivation to do something about the knowledge. Let’s get to the WHY:

                                                            \n

                                                            I came to know of the theme by chance, navigating the web and\n suddenly coming to a strange photo of human experiencing, the\n description of Unit 731. I searched more about it and was simply\n astonished to know it happened, and inflicted by the so-estimated\n Japan, a headquarter of technology and populated by reverent\n people. We are (that is, I am) often so biased,\n for the good or the bad.

                                                            \n

                                                            That is, what the general public know about World War II,\n including me? The holocaust of the Jews. This is much, but more\n happened, and more can be known for our critical view of the\n World, the countries and its interests, and the rational thinking\n that might be better with this knowledge.

                                                            \n

                                                            The Unit 731 was not the only one with deadly human\n experimentation, other facilities existed, but 731 came to be\n better known; first, it was hidden, but now, decades after the\n events, documents and confessions came to the ground and can’t be\n denied anymore. And in other sites, Shirō Ishii was already\n inflicting them probably since the fall of 1933, mainly Chinese\n people, but also Soviets, Mongolians and Koreans, men, women and\n children.

                                                            \n

                                                            That’s basically it. The research I made (and the movie I saw, a\n fiction, based on it, horrendous) led me to dream about the theme,\n so I felt to throw it, what was developed and developing inside,\n in some manner. I like the voice, the radio, and it is accessible\n to do, not requiring many equipments etc., so my first choice was\n to tell it. How? At first, I\n hypothetized about proposing a script to some Brazilian podcast\n that tell stories. Soon I realized it could not fit so well in the\n lines of the ones I know. Some days after, the idea of a little\n fictionalized story, short story, came as a thing I like, and also\n with the advantages of: 1. being beautiful (men is made of\n stories, real or otherwise appropriated by the mind and senses);\n 2. being impactful (connection with characters); 3. being fast in\n the way I proposed it to be (one little episode). Not necessarily\n only this or in this order, but the idea was that.

                                                            \n

                                                            One thing more, of course: as any interested in the subject can\n note, there is so many technical things produced about it, I\n wanted to do something that caught the emotions and interest of\n people, spreading the possibility of them knowing what, elsewhere,\n they wouldn’t come to see. I wanted to make it different in that\n sense, but as true to the facts as a little audio fiction can be.\n It’s History to our minds, for our own construction and of our\n world view. But, if not, if the listener just come for the art, it\n can be (I hope) an enjoying story after all. That was the WHY I\n decided to do something with the knowledge (in an expression, fire\n in my heart), and HOW it became a fiction podcast (to do\n something I like, and different about the subject, attractive).

                                                            That was my theme here for our moment in HPR! The motivation\n behind need to create. It was hard, I get moved easily\n with shocking scenes in words or images, but It catched me.\n Deciding how to “let go” and then producing it was not tranquil,\n also; the hands-on, the technical part, was as\n follows:

                                                            \n

                                                            I have written some pages summarizing the events I have outlined\n here. Having the base, I came with a story in my mind and in two\n days or three I think I wrote it, in 3 and a half pages, the story\n that you’re going to listen. In a more silent night I went to my\n room, with my notebook and a USB condenser microphone, and\n recorded. Fast. The editing, cutting, compressing, normalizing,\n and choosing free sounds (all referenced in description) and\n fitting them in the story, took a long and time and patience,\n maybe 10 or more dedicated hours along days. I’m not very\n efficient, some of it was the necessary lack of hurry of art, but\n some was my slowness in getting to the technical part of what I\n wanted to do (this bit of information in this milisecond, move\n track 3 together with track 4 without affecting the sync of the\n other tracks and clips in the same track, cut the music at this\n point but with a gentle fade…). I used Audacity. I had a\n Reaper licence (I remember being a bit more efficient with it) but\n lost it after formatting without having the serial number anymore,\n so I went with my long-choice of the free and open source\n alternative.

                                                            That was my work for the audiodrama podcast in my language.\n Which, in between the days I have been preparing this presentation\n script for HPR, I have released. You may find it in the\n description, or searching in your podcast app for the name (in\n Portuguese): “O Departamento de Prevenção de Epidemias e\n Distribuição de Água”, under the author name “Sem Luz em Saint\n Louis”.

                                                            Thank God we know that, from the beginning, man has lived in war.\n It’s envy, a desire for power, a desire for money. It is never a\n good motivation, but purely selfishness. I arrived at the\n department a week ago and, although I have no desire to\n collaborate with what happens here, I know enough to realize that\n it is impossible to leave this place free.

                                                            \n

                                                            When the Japanese invaded this region, Manchuria, in the long war\n against China, we did not expect the brutality that was witnessed.\n A few years ago, after the end of the Great War, several countries\n signed the Geneva Protocol. Although it only prohibits the use of\n chemical weapons, biological agents, asphyxiating, and related\n specificities, we believed it would mean more — that it would\n signify a general humanization of combat methods on land, sea, and\n air when there might be another Great War. I did not expect it to\n come in my lifetime nor to be captured to participate in it\n firsthand.

                                                            \n The first step is to plan the episode. What will it be about and\n also consider the purpose of the show: is it to introduce a topic,\n give information, entertain, be a tutorial or instructional, an\n informal yarn.

                                                            \n

                                                            \n Write down the points that you want to cover and any links that\n you are going to reference. This will help you when it comes to\n recording and also it can act as your show notes.

                                                            \n

                                                            \n For early stage simple and effective recording use your mobile\n phone. I recommend \n \n Audio Recorder\n \n as it allows you to record in WAV, you can change the sample rate\n and it doesn't include adverts or any features that are paid for\n only.

                                                            \n

                                                            \n \n

                                                            \n

                                                            \n For recording on a Linux desktop I would recommend using something\n simple like \n \n Reco\n \n .

                                                            \n

                                                            \n \n

                                                            \n

                                                            \n If you want to record a show with somebody else then you will need\n to use a PC as Google banned applications that have the ability to\n record calls. To do this with Reco you simply click on the \n Record from\n button and you are given the choice of microphone, system audio or\n both. Set this to \n both\n and whichever way you chat Reco will record the conversation.

                                                            \n

                                                            \n Once you have recorded your file then simply head to the HPR\n website:

                                                            One way in which the Fediverse is different from corporate social\nmedia is that there is no center. By definition, these platforms are a\nfederation of independent servers. This has consequences in that you may\nhave a server that is run by a single person and if that person gets\ntired of doing it, or faces life situations that get in the way, your\nserver may have to go away. But the mechanisms are in place to handle\nthis situation. I am going to explain in this short episode how you\nmigrate from one server to another.

                                                            If you have a running Linux system, then you have an example of what SELinux requires for normal operation. You don't have to learn about security contexts or memorize labels. For most anything you try to do on your computer, there are likely already files doing something similar. Use those files as templates.

                                                            \n

                                                            You can look at the security labels of any file you have access to by using the 

                                                            -Z
                                                            (that's a capital Z) option of 
                                                            ls
                                                            :

                                                            \n

                                                            $ touch hellotouch hello.txt\n$ ls -Z hello.txt\nunconfined_u:object_r:user_home_t:s0 hello

                                                            \n

                                                            An empty file created by a user in the user's own home directory has, as you might expect, a very specific security profile. Even with the executable bit set, that file would not be permitted to run as a systemwide service. It just doesn't have the correct security context.

                                                            \n

                                                            If you use an 

                                                            ll
                                                            alias, try adding the 
                                                            -Z
                                                            option to its option list so you get used to seeing SELinux labels. The more you see what labels exist on your system, and how they relate to various system roles, you're more likely to recognize when they're wrong.

                                                            Suppose you were developing a custom SELinux service for your laptop. You've written a shell script, a service file, and you've placed them in the appropriate system locations. You're also careful to set ownership and permissions correctly. But no matter what you do, you get errors when attempting to start the service.

                                                            \n

                                                            You suspect that SELinux might be preventing an unrecognized service from running. That would normally be appreciated, but in this case you want to make an exception.

                                                            \n

                                                            First, confirm that the service runs successfully with SELinux in Permissive mode:

                                                            \n

                                                            $ sudo setenforce Permissive\n$ sestatus | grep Current\nCurrent mode:                 permissive\n$ sudo systemctl start hello.service || echo \"fail\"\n$\n$ sudo setenforce Enforcing

                                                            \n

                                                            Then look at the files you've created using the 

                                                            -Z
                                                            and compare them with other files that you know to be working properly. Note the differences:

                                                            \n

                                                            $ ls -Z /usr/lib/systemd/system/hello.service\nunconfined_u:object_r:systemd_unit_file_t:s0\n$ ls -Z /usr/lib/systemd/system/rdisc.service\nsystem_u:object_r:rdisc_unit_file_t:s0

                                                            \n

                                                            The working service (

                                                            rdisc.service
                                                            in this example, chosen at random) features the 
                                                            system_u
                                                            label as well as a special 
                                                            rdisc_unit_file_t
                                                            label. Suppose you know from previous experience with 
                                                            ls -Z
                                                            that a common SELinux label for systemd service files is 
                                                            systemd_unit_file_t
                                                            so you ignore that difference. However, 
                                                            unconfined_u
                                                            and 
                                                            system_u
                                                            seem to be important.

                                                            \n

                                                            Use the 

                                                            chcon
                                                            (\"change context\") command to change the security context of your service file:

                                                            \n
                                                            \n$ sudo chcon system_u:object_r:systemd_unit_file_t:s0 \\\n/usr/lib/systemd/system/hello.service\n$ ls -Z /usr/lib/systemd/system/hello.service\nsystem_u:object_r:systemd_unit_file_t:s0\n
                                                            \n

                                                            Your systemd service is probably triggering some executable file on your system. If you created that yourself, it probably also has the incorrect security context. Comparing it to a known working script:

                                                            \n

                                                            $ ls -Z /usr/bin/example.sh\nunconfined_u:object_r:gconf_home_t:s0\n$ ls -Z /usr/bin/brltty-prologue.sh\nsystem_u:object_r:bin_t:s0

                                                            \n

                                                            Again, there's one obvious difference, which you can correct with 

                                                            chcon

I tested it with some BSD systems and installed Indie Archive without a GUI. Ghost BSD didn't install but Midnight BSD did install so I used the Midnight BSD GUI and installed Indie Archive. None of this was easy for me because I'm a BSD newb and unless you already use BSD I can't recommend it for Libre Indie Archive. Remember, not all indie producers are computer programmers, and I want Indie Archive to work for those producers as well as for the computer savvy.

                                                            \n

                                                            \n

                                                            \nThen on a whim I thought I would try the Xubuntu 24.04 distro and it installed no problems. Thanks XFCE for keeping it light.

                                                            \nThe other reason I am developing and documenting for Xubuntu is that I can use the Xubuntu install document and install on Ubuntu or Debian with only minor differences. I know because I tried it. This is probably also true for other Debian and Ubuntu derived distributions.

                                                            \n

                                                            \n

                                                            \nSo, if you want to help, you could take the Xubuntu install document and see if it works on other distributions. Write down what you had to change and let me know. I plan on making an install checklist out of the install document and it would be great to have a checklist with the actual commands for several distributions.

                                                            \nSo, that was the intro. Now on to the topic.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nI am planning on installing remotenear and remotefar systems, remotenear being a short drive away (or maybe in your home if your studio is not in your home, like mine) and the remotefar further away to avoid losing data in the case of a regional catastrophe like flood, fire, tornado, or hurricane.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nStill even a short drive is not what I want to do any time there might be something I need to check on a remote system so I have devised a way to manage it from the secondary system.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nWhen a remote system is delivered to a new location it will be headless. No monitor, no keyboard, and no mouse. At the remote location it is plugged into a UPS and attached to the network with an ethernet cable and attached to the UPS with a usb cable. Then it is turned on.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nEven without a keyboard or a mouse there is still some local control of the system available. As part of the remote system install we go into the power management settings and next to \"when power button is pressed\" we select shutdown.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nSo, a short press on the power button initiates a Xubuntu shutdown just like the shutdown that you get from the menu or Alt F4.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nIf that doesn't work a long press of the power button will turn the system off. This is like unplugging the system or losing power and is not recommended but Xubuntu will rebuild the file structure when the system is restarted.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nAnd if you do lose power the UPS will send a signal to the computer shutting it down with a controlled shutdown, just like a short press of the power button or a shutdown from the menu.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nI would like to carry this one step further and enable automatic power up for the computer. A quick search shows cyberpower PowerPanel software for linux. Also you can set a power restore function in the BIOS to restart the system when the power is restored. I just checked and this worked on my little HP.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nSo ... with just the power button and an attached UPS you can get both manual and automatic control of shutting the remote system down and restarting it.

                                                            \nPretty cool for a rather sparse interface.

                                                            \nIf you know more about how to set this up please let me know. There's a big jump between doing a search to see if something is possible and actually implementing it.

                                                            \nOkay, that was the easy part. Now for the fun part.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nFirst off, the remote system is probably not going to be at your place but at the home or business of friends or family. And they probably don't have a static IP, and they may not be able to implement port forwarding in their router, and they may not be able to control their firewall.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nSo we can't go, \"I'll just ssh in when I need to fix a problem\". And you don't really want to change their setup anyway because all of the above add to their security risk.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nAlso their router undoubtedly gives dynamic IP addresses so we want the remote system to use that because when we are setting it up we might not even know what subnet their LAN uses.

                                                            \n

                                                            \n
                                                            \n

                                                            \n

                                                            \nBut, at the same time it doesn't make any sense at all to try to maintain a remote system that you can't log into.

                                                            \n

                                                            \n

                                                            \nSo, the tool for setting up a terminal session on the remote system is called a remote tunnel reverse shell. The remote system is already connecting to the secondary system with rsync ssh when the cron job fires off every day to update the files. So, the secondary system is running an ssh server and the remote system has the public key that allows access without entering a password.

                                                            \nThere are two parts to setting up a remote tunnel reverse shell. The secondary system has to be listening for the remote system on a port, I use port 7070. And then the remote system runs a bash command with the -i parameter that means reverse shell, and with the port, 7070.

Except on your LAN the ip address may be different.

                                                            \nSo when I was testing the email notifications part of check.sh and fiddling around with the code all of a sudden I quit getting notifications at all. I learned a lot about bash scripting trying to figure out what I did wrong and it turned out it wasn't me.

                                                            \nAfter I sent myself numerous emails saying yes from a weird email address gmail decided they were spam. So I went into my spam folder and marked the notification email as not spam. That fixed it for me but if you are setting up email notifications for Libre Indie Archive or for anything be sure you white list the email address so that the email powers that be don't suddenly decide that your notifications are spam and you quit getting important notifications.

                                                            \nIn gmail you set up a filter entry with the notifier's email address and set the action to be \"Never send it to Spam\".

                                                            \nBecause getting these emails is important. First they remind me to have the secondary system listen. Then they remind me to change letmein.txt from yes to no after I'm done with the remote terminal. And while you're changing letmein.txt to no make sure the listener is off. Leaving it listening for an extended period of time is a security risk.

                                                            Learning to use the terminal is an important step in becoming a\n true power user of Linux, but it’s easy (and normal) to make\n mistakes along the way. Here are the top 5 mistakes new terminal\n users make, and what you can learn from them.

                                                            \n

                                                            1. Current working directory

                                                            \n

                                                            When you first open a terminal, your current working directory\n is your home folder. You have access to all those directories\n you see in your home directory every time you open a file\n manager (Desktop, Documents, Downloads,\n Music, Pictures, and Videos).\n You can verify your location with the pwd command:

                                                            \n 
                                                            $ pwd\n/home/seth
                                                            \n

                                                            You can list the files and folders within your current\n directory with the ls or dir or tree\n commands:

                                                            \n 
                                                            $ ls\nDesktop  Documents  Downloads\nMusic    Pictures   Videos
                                                            \n

                                                            But you don’t usually stay in one place while using the\n terminal. You frequently move from folder to folder so you can\n open or modify or edit files. It’s easy to get lost, forgetting\n what directory you’re in and what files are around you.

                                                            \n

                                                            Lesson learned: When working in the terminal,\n it’s important to regularly verify your current working\n directory with pwd so you don’t accidentally issue\n a command you intended to run in a different location.

                                                            \n

                                                            2. Use interactive options when using\n wildcards

                                                            \n

                                                            Wildcards are great shorthand to make command entry faster, and\n to perform bulk actions on lots of files. However, they can be\n dangerous when you get them wrong.
                                                            \n It’s easy to process hundreds of the wrong files by using a\n wildcard in the wrong directory, or by using a wildcard that’s\n too broad.

                                                            \n

                                                            For example, suppose you want to run a sed\n command on all HTML files in a directory, so you run this:

                                                            \n 
                                                            $ sed --in-place 's/day/night/g' *ml
                                                            \n

                                                            Job done, until you find out that you accidentally ran that\n command on all your XML files, too.

                                                            \n

                                                            Lesson learned: Run a safe test command on the\n wildcard you think you want to target before making a\n change. Some commands have a literal --dry-run\n option. Others have an --interactive option that\n forces the command to prompt you to confirm that you want to\n carry out the action. Sometimes the logic is reversed: a command\n refuses to make a major change unless you use a command (for\n example, sed doesn’t write changes to a file\n without the --in-place option or redirection).

                                                            \n

                                                            When in doubt, improvise. You can always “expand” a wildcard\n using the echo command:

                                                            \n 
                                                            $ echo ./*ml\n./four.html ./one.xml ./three.html ./two.xml\n$ echo ./*tml\n./four.html ./three.html
                                                            \n

                                                            3. File paths

                                                            \n

                                                            Many new terminal users don’t understand where files are\n located within the file system. It’s not a common mistake to\n make on the desktop because there are visual reminders there.\n You wouldn’t try to double-click on a document to open it if\n there was no icon to double-click. It’s easy to assume that the\n terminal application contains all your files all at once, but\n the terminal is, by design, limited in scope. Were the terminal\n to have access to every file everywhere on your system all at\n once, you’d end up accidentally renaming and moving and copying\n a lot more files than intended. Specificity is a super power,\n and it’s defined by the file path.

                                                            \n

                                                            A file path describes where a file exists in a file system. A\n full (or “absolute”) file path always starts from the single\n folder at the start of your operating system, indicated by just\n a /, and then lists each folder within that folder\n until it traces the path to a specific file. For example, I have\n a file called IMG_0001.JPG in my Pictures\n directory. You probably have a mental image of where that file\n is and how you’d get there on the desktop. But for the terminal\n to understand how to find it, the location must be expressed as\n /home/seth/Pictures/IMG_0001.JPG.

                                                            \n

                                                            An absolute file path is definitive. The terminal always\n understands an absolute file path, no matter what your current\n working directory is.

                                                            \n

                                                            The absolute path to a file can be unwieldy, though. Once you\n understand absolute paths, you can abbreviate any path to a relative\n file path.

                                                            \n

                                                            A relative file path is based on your current location in the\n terminal. As long as you’re in the Pictures\n folder, the full path /home/seth/Pictures/IMG_0001.JPG\n can be shortened to just IMG_0001.JPG, or ./IMG_0001.JPG\n for added clarity (the . indicates no movement\n from your current location, and the / is a\n directory separator as usual).

                                                            \n

                                                            But suppose your current working directory was your home\n directory. Your Pictures folder is located in your\n home directory, so to get to IMG_0001.JPG you have\n to enter Pictures first. The relative path in that\n case is ./Pictures/IMG_0001.JPG or just Pictures/IMG_0001.JPG.

                                                            \n

                                                            Lesson learned: An absolute file path always\n starts from the start of a file system. A relative file path\n changes based on your location. The terminal understands both.\n For new users, the absolute file path is the most explicit and\n exact way to reference a file, so practice using them until\n you’re comfortable with the concept of file paths.

                                                            \n

                                                            4. Executable permissions

                                                            \n

                                                            By default, most files aren’t executable. You can’t run them\n like an application, because most files are meant to be opened in\n an application. That’s not true for shell scripts, though.

                                                            \n

                                                            Shell scripts are text files containing a list of commands, and\n they’re meant to be run like an application. They’re a powerful\n way to string existing commands together to form a new custom\n command. However, because a shell script starts out as a regular\n text file, it’s not seen by your terminal as an executable\n entity.

                                                            \n

                                                            To execute a file as an application, you can grant it\n executable permission with the chmod command:

                                                            \n 
                                                            $ chmod +x ./example.sh
                                                            \n

                                                            Alternatively, you can run the file in a sub-shell:

                                                            \n 
                                                            $ bash ./example.sh
                                                            \n

                                                            Notice that in these examples, I use the ./\n notation as if the example.sh shell script exists\n in my current directory.

                                                            \n

                                                            5. Typing errors

                                                            \n

                                                            It sometimes feels like the more you type, the more you’re\n getting done. In a terminal, though, typing too much is one of\n the best ways to introduce mistakes.

                                                            \n

                                                            When you try to type a long and complex command, you’re liable\n to spell something wrong or use the wrong option. When you try\n to type a filename or a file path, you might forget to escape\n special characters (like spaces). The errors aren’t usually\n catastrophic, but they’re frustrating and time consuming.

                                                            \n

                                                            Lesson learned: There are several ways to\n ensure you’re entering the correct commands into your terminal:

                                                            \n
                                                              \n
                                                            • Copy and paste: If you’re using a command\n you found on a trusted website, copy it in your browser and\n then paste it into your terminal using Ctrl+Shift+V\n or right-click and select Paste.
                                                              • \n
                                                            • TAB: You can type part of a command or file\n path, and then press the TAB key on your\n keyboard for either auto-completion or for suggested\n completions. Use it even when you don’t think you need it.\n It’ll save you errors every single time, even when\n it appears to not work (hint: it’s not working because you’re\n trying to auto-complete something that’s not where you think\n it is).
                                                              • \n
                                                            • Drag-and-drop: It’s the 21st century! You\n can drag a file or folder from anywhere on your computer, and\n drop it into your terminal. It gets replaced by its absolute\n path automatically.
                                                              • \n
                                                            \n

                                                            Practice makes perfect

                                                            \n

                                                            To get good in the terminal, you have to use it as often as you\n can. You don’t have to use it for “serious” work at first, and\n you arguably shouldn’t, but you can and should do simple\n exercises in the terminal. Understand file paths, get used to\n wildcards, learn shortcuts, use the TAB key.\n The biggest mistake you can make when learning the terminal is\n to not use the terminal, so open it up every day, do your\n exercise, and you’ll be an expert in the terminal in no time.

                                                            \n

                                                            \n Foreign adversaries have colonized America’s computers from at\n least 1986. Four decades later, online safety is the largest\n failure in the history of human engineering. Radical stewardship\n in cybersecurity would bring radical progress, but responsibility\n for losses will need to flow from the bottom up. The buck stops\n with victims, who must accept all blame for cyberattacks. Only\n then will people at risk properly vet the products and vendors\n they select.

                                                            \n

                                                            \n A leading challenge in stewardship is balancing the opaque,\n proprietary nature of VLSI complex logic with the owner’s need for\n complete control. Since these aspects are incompatible and owner\n control is essential, it’s necessary to design computers that\n avoid complex VLSI entirely. One such architecture, Dauug | 36, is\n being developed at Wright State University to deliver 36-bit\n computing, preemptive multitasking, paged virtual memory, and\n hundreds of opcodes, all without using a single microprocessor or\n anything like one.

As a disadvantage, they catch even minimal sound details of the environment, vibrating with little sound waves around, even distant. That’s why you might get as recording result the clear details of noise from the street, or reverberation (echo) of an untreated room if you use it without the best environment. \n(If it’s ok for you even in these situations, it’s a merit of other factors, not a merit of the condenser diaphragm)\n. \nUsage\n: A favorite of singers in studio, among several other applications. As you can see on videos of professionals singing, one don’t talk on top of it (which might produce a low and undesired muffled sound) but on the side — and on the correct side, because most models of microphones have a cardioid pollar pattern.

It’s the best for amateur use, or in a room without acoustic treatment. \nUsage\n: \nMusicians\nperforming live use dynamic microphones so the instruments (and crowd) around don’t get their sound amplified by this artist’s microphone. \nRadios\nprefer dynamic mics, because it goes to a more impactful voice, rejects eventual sounds from noisy mixers or keyboards nearby that the radio host might be operating.

For example, some are omnidirectional (captures sound equally from all the sides); most of them are cardioid, capturing the sound coming from the front (the speaker, the instrument directed to it), but rejects sound from the rear.

                                                            \n

                                                            \n. So you can easily find what is the part you have to change or write, and only delete the * when you do that part. At the end, you can check if there is any * remaining, if not, the document is ready.

It’s a one by one process, but once for all.

                                                            I found this book while searching for forths for the arduino uno\n boards. the source code and documentation for eforth is available\n in a lot of places I will put a few links in the show notes.

                                                            When I first encountered dr tings forth for arduino I was\n interested for one reason, it was easily assembled using avra, the\n gnu port of the atmel assembler. this was nice because using\n atmels (now microchips) assemblers on Linux required installing\n wine and installing wine, in the past, on a 64 bit Slackware meant\n installing 32 bit libraries to have a multI lib Slackware. ( that\n not an issue now). assembling the forth code in avra is quick, its\n only a little bit over 5k in size in the end.

                                                            \n After playing with eforth for a while I became frustrated because I\n could create new words in the dictionary and the examples ran fine,\n but nothing persisted across reboot. so I dropped eforth and ended\n up using flashforth, which is a great, robust full featured forth. I\n still recommend flashforth if your starting out with forth on a\n microcontroller its solid software with good documentation.

                                                            \n At the end of last year I thought it would be fun to write my own\n forth. and after looking into doing that I revisited 328eforth and\n thought, no how about I fix the problems with eforth on the arduino.\n so I dug out the book and began reading.\n

                                                            \n Transferring Large Data Sets

                                                            \n

                                                            \n Very large data sets present their own problems. Not everyone has\n directories with hundreds of gigabytes of project files, but I do,\n and I assume I'm not the only one.

                                                            \n

                                                            \n For instance, I have a directory with over 700 radio shows, many\n of these directories also have a podcast, and they also have\n pictures and text files.

                                                            \n

                                                            \n Doing a properties check on the directory I see 450 gigabytes of\n data.

                                                            \n

                                                            \n When I started envisioning Libre Indie Archive I wanted to move\n the directories into archival storage using optical drives. My\n first attempt at this didn't work because I lost metadata when I\n wrote the optical drives since optical drives are read only.

                                                            \n

                                                            \n After further work and study I learned that tar files can preserve\n meta data if they are created and uncompressed as root. In fact,\n if you are running tar as root preserving file ownership and\n permissions is the default.

                                                            \n

                                                            \n So this means that optical drives are an option if you write tar\n archives onto the optical drives.

                                                            \n

                                                            \n I have better success rates with 25 GB Blue Ray Discs than with\n the 50 GB discs. So, if your directory breaks up into projects\n that fit on 25 GB discs, that's great.

                                                            \n

                                                            \n My data did not do this easily but tar does have an option to\n write a data set to multiple tar files each with a maximum size,\n labelling them -0 -1, etc.

                                                            \n

                                                            \n When using this multi volume feature you cannot use compression.\n So you will get tar files, not tar.gz files.

                                                            \n

                                                            \n It's better to break the file sets up in more reasonable sizes so\n I decided to divide the shows up alphabetically by title, so all\n the shows starting with the letter a would be one data set and\n then down the alphabet, one letter at a time.

                                                            \n

                                                            \n Most of the letters would result in a single tar file labeled -0\n that would fit on the 25 GB disc. Many letters, however, took two\n or even three tar files that would have to be written on different\n disks and then concatenated on the primary system before they are\n extracted to the correct location in primaryfiles.

                                                            \n

                                                            \n There is a companion program to tar, called tarcat, that I used to\n combine 2 or 3 tar files split by length into a single tar file\n that could be extracted.

                                                            \n

                                                            \n I ran engrampa as root to extract the files.

                                                            \n

                                                            \n So, I used a tar command on the working system where my Something\n Blue radio shows are stored. Then I used K3b to burn these files\n onto a 25 GB Blu Ray Disc carefully labeling the discs and writing\n a text file that I used to keep up with which files I had already\n copied to Disc.

                                                            \n

                                                            \n Then on the Libre Indie Archive primary system I copied from the\n Blu Ray to the boot drive the file or files for that data set.\n Then I would use tarcat to combine the files if there was more\n than one file for that data set. And finally I would extract the\n files to primaryfiles by running engrampa as root.

                                                            \n

                                                            \n Now I'm going to go into details on each of these steps.

                                                            \n

                                                            \n First make sure that the Libre Indie Archive program, prep.sh, is\n in your home directory on your workstation. Then from the data\n directory to be archived, in my case the something_blue directory\n run prep.sh like this.

                                                            \n 
                                                            \n~/prep.sh
                                                            \n

                                                            \n This will create a file named IA_Origin.txt that lists the date,\n the computer and directory being archived, and the users and\n userids on that system. All very helpful information to have if at\n some time in the future you need to do a restore.

                                                            \n

                                                            \n Next create a tar data set for each letter of the alphabet. (You\n may want to divide your data set in a different way.)

                                                            \n

                                                            \n Open a terminal in the same directory as the data directory, my\n something_blue directory, so that ls displays something_blue (your\n data directory). I keep the Something Blue shows and podcasts in\n subdirectories in the something_blue directory.

                                                            \n

                                                            \n Here's the tar command.

                                                            \n

                                                            \n Example a:

                                                            \n 
                                                            \nsudo tar -cv --tape-length=20000000 --file=somethingblue-a-{0..50}.tar /home/larry/delta/something_blue/a*
                                                            \n

                                                            \n This is for the letter a so the --file parameter includes the\n letter a. The numbers 0..50 in the squirelly brackets are the\n sequence numbers for the files. I only had one file for the letter\n a, somethingblue-a-0.tar.

                                                            \n

                                                            \n The last parameter is the source for the tar files, in this case

                                                            \n 
                                                            \n/home/larry/delta/something_blue/a*
                                                            \n

                                                            \n All of the files and directories in the something_blue directory\n that start with the letter a.

                                                            \n

                                                            \n You may want to change the --tape-length parameter. As listed it\n stores up to 19.1 GB. The maximum capacity of a 25 GB Blu-ray is\n 23.3GB for data storage.

                                                            \n

                                                            \n Example b:

                                                            \n

                                                            \n For the letter b, I ended up with three tar files.

                                                            \n 
                                                            somethingblue-b-0.tar
                                                            somethingblue-b-1.tar
                                                            somethingblue-b-2.tar
                                                            \n

                                                            \n I will use these files in the example below using tarcat to\n combine the files.

                                                            \n

                                                            \n I use K3b to burn Blu-Ray data discs. Besides installing K3b you\n have to install some other programs and then there is a particular\n setup that needs to be done including selecting cdrecord and no\n multisession. Here's an excellent article that will go step by\n step through the installation and setup.

                                                            \n I also always check Verify data and I use the Linux/Unix file\n system, not windows which will rename your files if the filenames\n are too long.

                                                            \n

                                                            \n I installed a Blu-Ray reader into the primary system and I used\n thunar to copy the files from the Blu-Ray Disc to the boot drive.

                                                            \n

                                                            \n In the primaryfiles directory I make a subdirectory,\n something_blue, to hold the archived shows.

                                                            \n

                                                            \n If there is only one file, like in example a above, you can skip\n the concatenation step.

                                                            \n

                                                            \n If there is more than one file, like Example b above, you use\n tarcat to concatenate these files into one tar file.

                                                            \n

                                                            \n You have to do this. If you try to extract from just one of the\n numbered files when there is more than one you will get an error.\n So if I try to extract from somethingblue-b-0.tar and I get an\n error it doesn't mean that there's anything wrong with that file.\n It just has to be concatenated with the other b files before it\n can be extracted.

                                                            \n

                                                            \n There is a companion program to tar called tarcat that should be\n used to concatenate the tar files.

                                                            \n

                                                            \n Here's the command I used for example b, above.

                                                            \n 
                                                            \ntarcat somethingblue-b-0.tar somethingblue-b-1.tar somethingblue-b-2.tar > sb-b.tar
                                                            \n

                                                            \n This will concatenate the three smaller tar files into one bigger\n tar file named sb-b.tar

                                                            \n

                                                            \n In order to preserve the meta data you have to extract the files\n as root. In order to make it easier to select the files to be\n extracted and where to store them I use the GUI archive manager,\n engrampa. To run engrampa as root open a terminal with CTRL-ALT t\n and use this command

                                                            \n 
                                                            sudo -H engrampa
                                                            \n

                                                            \n Click Open and select the tar file to extract. Then follow the\n path until you are in the something_blue directory and you are\n seeing the folders and files you want to extract. Type Ctrl a to\n select them all. (instead of the something_blue directory you will\n go to your_data directory)

                                                            \n

                                                            \n Then click Extract at the top of the window. Open the directory\n where you want the files to go. In my case,\n primaryfiles/something_blue

                                                            \n

                                                            \n Then click Extract again in the lower right.

                                                            \n

                                                            \n After the files are extracted go to your data directory in\n primaryfiles and check that the directories and files are where\n you expect them to be.

                                                            \n

                                                            \n You can also open a terminal in that directory and type

                                                            \n 
                                                            \nls -l
                                                            \n

                                                            \n to review the meta data.

                                                            \n When dealing with data chunks sized 20 GB or more each one of these\n steps takes time. The reason I like using an optical disk backup to\n transfer the files from the working system to Libre Indie Archive is\n because it gives me an easy to store backup that is not on a\n spinning drive and that cannot be overwritten. Still optical disk\n storage is not perfect either. It's just another belt to go with\n your suspenders.\n

                                                            \n Another way to transfer directories into the primaryfiles\n directory is with ssh over the network. This is not as safe as\n using optical disks and it also does not provide the extra\n snapshot backup. It also takes a long time but it is not as labor\n intensive.

                                                            \n

                                                            \n After I spend some more time thinking about this and testing I\n will do a podcast about transferring large data sets with ssh.

                                                            \n

                                                            \n Although I am transferring large data sets to move them into\n archival storage using Libre Indie Archive there are many other\n situations where you might want to move a large data set while\n preserving the meta data. So what I have written about tar files,\n optical discs, and running thunar and engrampa as root is\n generally applicable.

                                                            First, I create a Git repository some place on the server. This\n is the Git repo that's going to be populated with your content,\n but it doesn't have to be in a world-viewable location on your\n server. Instead, you can place this anywhere, and then use a Git\n hook or a cronjob to copy files from it to a world-viewable\n directory. I don't cover that here. I refer to this location as\n the staging directory.

                                                            \n

                                                            Next, create a bare repository on your server. In its hooks\n directory, create a shell script called post-receive:

                                                            \n 
                                                            #!/usr/bin/bash\n#\nwhile read oldrev newrev refname\ndo\n       BR=`git rev-parse --symbolic --abbrev-ref $refname`\n       if [ \"$BR\" == \"master\" ]; then\n               WEB_DIR=\"/my/staging/dir\"\n               export GIT_DIR=\"$WEB_DIR/.git\"\n               pushd $WEB_DIR > /dev/null\n               git pull\n               popd > /dev/null\n       fi\ndone \n
                                                            \n Now when you push to your bare repository, you are triggering the\n post-receive script to run, which in turn triggers a git pull in\n your staging directory.\n

                                                            Once your staging directory contains the content you want to\n distribute, you can copy them to live directories, or you could\n make your staging directory live (remember to exclude the .git\n directory though), or whatever you want.

                                                            \n

                                                            For gopher, I create a file listing by date using a shell\n script:

                                                            \nThe water from the tap is safe, recognized as drinking water (in my city, and maybe in many if not most). The water treatment company (\"Sanepar\") here even sells their water bottled, and sponsors events that distribute them (sports events) to show the quality.
                                                            \nBut people don't use to drink from the tap it directly. If they do not use a filter, it's common to buy water in 20 liters carboys \n(big plastic bottles, 20L is a bit more than 5 gallons)\n. I use this last option, but drink water under the shower also.
                                                            \nMost people (that I know, of course) simply \ndon't drink water\n! I don't know. I don't understand how it is, but they don't drink water, not even a liter per day. Coffee and soda are the most common \"substitutes\".\n

                                                            \nStatistics about religion are very misleading. You can find different numbers but it's generally: more than half identifying as Catholics. More than 20% evangelical, 10% without religion.
                                                            \nBut those numbers say nothing about reality of what you find in the streets. Maybe because in some areas it's embarassing to identify as an atheist, as if you're immoral and cannot be trusted; so, people without religion simply say the religion of the family, or the generic \"catholic, non-practicing\".\n

                                                            \nIn many other parts of the country, of course, it's different. For example, I lived in a capital city on the north, and everybody expected you to say \nGood Morning!\n when entering an elevator in the morning, behavior that generally makes people think you're strange here in my southern city.

                                                            \n

                                                            \nWhen I thought back I remembered that my PC was running a bit slower than usual and that that the lack of space in the root partition could have been to blame.

                                                            \nIt’s not a good idea to try and resize and or move a mounted filesystem so a bootable live version of Gparted would be a good idea. The reason for this is that if you run Gparted from your normal Linux OS and the OS decides to write something to the disk while Gparted is also trying to write or move things on the disk then as you could imagine very bad things could and probably would happen.

                                                            \n

                                                            \nI booted up the live CD and setup the various operations such as shrinking the home partitions, moving it to the right to leave space for the root partition then finally increasing the size of the almost full root partition.

At this point I thought / hoped that nothing had actually happened. My guess was that the old live Gparted distribution I was using didn’t support Ext4 though I could be completely wrong on this.

                                                            \nThis still left me with the original problem in that I had little free space on my root filesystems.

                                                            \n

                                                            \nThis time I decided to take my time and break the task up into smaller chunks and not to do it in one go.

                                                            \n

                                                            \nFirst I downloaded the newest Live distribution version of Gparted

                                                            \n

                                                            \nI performed the checksum test to make sure the download was successful with no errors.

                                                            \n

                                                            \nThe next day I tried to write it to a CD-ROM something I haven’t done for a very long time.

                                                            \n

                                                            \nI initially couldn’t understand why I couldn’t click on the write button then I looked at my blank CD-ROM using the UBUNTU GNOME DISKS application. It reported that the disk was read only.

                                                            \n

                                                            \nI did a bit of goggling and came across a post saying that they had come across this and that they solved this by installing the CD-ROM writing application Brasero.

                                                            \n

                                                            \n\nWikipedia article about Brasero\n)

                                                            \n

                                                            \n\nOfficial website for Brasero\n

                                                            \n

                                                            \nInstalling Brasero solved the problem and allowed me to write the image file to CD-ROM. I was actually surprised that it wasn’t installed as I’ve used this application in the past. Just goes to show how long it’s been since I’ve written anything to CD-ROM!

                                                            \n

                                                            \nI booted the CD-ROM to check that Gparted worked and didn’t see any explanation marks on any of my partitions. I was short on time and didn’t want to rush things so decided to stop at this point.

                                                            \n

                                                            \nLater on I popped the live bootable Gparted CD-ROM running version 1.6.0.3 AMD 64 version into my PC and booted it up.

                                                            \n

                                                            \nEverything seemed okay and there were no errors showing.

                                                            \n

                                                            \nI took my home partition SDA6 and shrunk it down by about 20 GB and then shifted it 20 GB to the right to the end of the disk.

                                                            \n

                                                            \nThis left a 20 GB gap at the end of my root partition.

                                                            \n

                                                            \nI then increased the size of my root partition SDA5 by approximately 20 GB to fill the empty space.

                                                            \n

                                                            \nIt took Gparted about one hour and 40 minutes to complete all the operations.

                                                            \n

                                                            \nThe root partition is now reporting 61% full rather than 86% full.

                                                            \n

                                                            \nThe root partition is now approximately 53 GB in size with 31 GB used. 22 GB is now free which is a bit more comfortable.

                                                            \n\nPicture 1 \nIs a screenshot of GParted showing the new sizes of my root and home partitions.

                                                            \n

                                                            \nI removed the GParted CD from my CD-ROM drive and rebooted the PC to thankfully find all was well and no errors reported.

                                                            \n

                                                            I am using a Zoom H1essential\n Stereo\n Handy Recorder microphone, recording into Audacity for this\n show.

                                                            \n

                                                            Why visit the record shop?

                                                            \n

                                                            Picking up a record at the record shop expands my music\n choices.
                                                            \n I get a chance to talk to the owner on the weekend when searching\n for\n new music. He is an archaeologist and a teacher at a local college\n during\n the week, and is knowledgeable on all the music in the store.

                                                            \n

                                                            I wanted a way to listen to the records while on my laptop,\n preferably with headphones, as to not disturb the household.

                                                            \n

                                                            How is this accomplished?

                                                            \n

                                                            This is done using a combination of Darkice to capture the\n stream,\n and Icecast to stream it to the local network.

                                                            \n

                                                            What is Icecast?

                                                            \n

                                                            Icecast is a streaming media (audio/video) server which\n currently\n supports Ogg (Vorbis and Theora), Opus, WebM and MP3 streams. It\n can be\n used to create an Internet radio station or a privately running\n jukebox\n and many things in between. It is very versatile in that new\n formats can\n be added relatively easily and supports open standards for\n communication\n and interaction.

                                                            This is just an introduction, here is the rough text of the audio:

                                                            \n

                                                            Hello HPR:

                                                            \n

                                                            I'm murph, I've been an HPR listener for a long-time, into the TWAT days. I'll try to keep it quick.

                                                            \n

                                                            I started in computers in the early 80's with a VIC-20. After a few of the Commodore 8-bits, I settled into the Amiga line, which I daily drove up into this century, and stll have a few.

                                                            \n

                                                            In college in the 90's, I had a dilemma. I wanted to do C programming homework from home, but the expensive Amiga compiler wasn't compatible with the Sun workstations at school. Another student introduced me to Linux, and I promptly ordered a set of Slackware CDs and figured out how to install. I was looking for the compilers to complete my studies, but have stayed for the freedom, and the communities, like this one. I've used countless distros over the years, and use a few for different needs.

                                                            \n

                                                            I am still a Linux user, and system administrator. I've given a few talks on things like gnu/screen, mastodon, tmux ay conventions like Penguicon, SCaLE, HOPE and some more regional conferences.

                                                            \n

                                                            I was inspired by Lyle and Thaj Sera's HPR birds of a feather talk, and thought that it would make a good presentation, and asked them to let me base a talk off of it, which they encouraged. Part of that is how to submit a show, which resulted in me finally, after all this time, finally submitting one of my own, as opposed to the occassional show I've crassly barged into.

                                                            \n

Did it only with some testing, and knowing that sibilance normally is at about 6 kHz (when it happens, because here the dynamic microphone ended up not capturing too much of it).

                                                            \n

                                                            Password management is one of those computing problems you\n probably don't think about often, because modern computing usually\n has an obvious default solution built-in.

                                                            \n

                                                            A website prompts you for a password, and your browser auto-fills\n it in for you.

                                                            \n

                                                            Problem solved.

                                                            \n

                                                            However, not all browsers make it very easy to get to your\n passwords store, which makes it complex to migrate passwords to a\n new system without also migrating the rest of your user profile,\n or to share certain passwords between different users.

                                                            \n

                                                            There are several good open source options that offer\n alternatives to the obvious defaults, but as a user of Linux and\n UNIX, I love a minimal and stable solution when one is available.

                                                            \n

                                                            The pass command is a password manager that uses\n GPG encryption to keep your passwords safe, and it features\n several system integrations so you can use it seamlessly with your\n web browser of choice.

                                                            \n

                                                            Install pass

                                                            \n

                                                            The pass command is provided by the PasswordStore project.

                                                            \n

                                                            You can install it from your software repository or ports\n collection.

                                                            \n

                                                            For example, on Fedora:

                                                            \n 
                                                            \n$ sudo dnf install pass\n
                                                            \n

                                                            On Debian and similar:

                                                            \n 
                                                            \n$ sudo apt install pass\n
                                                            \n

                                                            Because the word pass is common, the name of the\n package may vary, depending on your distribution and operating\n system.

                                                            \n

                                                            For example, pass is available on Slackware and\n FreeBSD as password-store.

                                                            \n

                                                            The pass command is open source, so the source code\n is available at git.zx2c4.com/password-store.

                                                            \n

                                                            Create a GPG key

                                                            \n

                                                            First, you must have a GPG key to use for encryption.

                                                            \n

                                                            You can use a key you already have, or create a new one just for\n your password store.

                                                            \n

                                                            To create a GPG key, use the gpg command along with\n the --gen-key option (if you already have a key you\n want to use for your password store, you can skip this step):

                                                            \n 
                                                            \n$ gpg --gen-key\n
                                                            \n

                                                            Answer the prompts to generate a key.

                                                            \n

                                                            When prompted to provide values for Real name,\n Email, and Comment, you must\n provide a response for each one, even though GPG allows you to\n leave them empty.

                                                            \n

                                                            In my experience, pass fails to initialize when one\n of those values is empty.

                                                            \n

                                                            For example, here are my responses for purposes of this article:

                                                            \n 
                                                            \nReal name: Tux\n\nEmail: tux@example.com\n\nComment: My first key\n
                                                            \n

                                                            This information is combined, in a different order, to create a\n unique GPG ID.

                                                            \n

                                                            You can see your GPG key ID at any time:

                                                            \n 
                                                            \n$ gpg --list-secret-keys | grep uid\n\nuid:     Tux (My first key) tux@example.com\n
                                                            \n

                                                            Other than that, it's safe to accept the default and recommended\n options for each prompt.

                                                            \n

                                                            In the end, you have a GPG key to serve as the master key for\n your password store.

                                                            \n

                                                            You must keep this key safe.

                                                            \n

                                                            Back it up, keep a copy of your GPG keyring on a secure device.

                                                            \n

                                                            Should you lose this key, you lose access to your password store.

                                                            \n

                                                            Initialize a password store

                                                            \n

                                                            Next, you must initialize a password store on your system.

                                                            \n

                                                            When you do, you create a hidden directory where your passwords\n are stored, and you define which GPG key to use to encrypt\n passwords.

                                                            \n

                                                            To initialize a password store, use the pass init\n command along with your unique GPG key ID.

                                                            \n

                                                            Using my example key:

                                                            \n 
                                                            \n$ pass init \"Tux (My first key) <tux@example.com>\"\n
                                                            \n

                                                            You can define more than one GPG key to use with your password\n store, should you intend to share passwords with another user or\n on another system using a different GPG key.

                                                            \n

                                                            Add and edit passwords

                                                            \n

                                                            To add a password to your password store, use the pass\n insert command followed by the URL (or any string) you\n want pass to keep.

                                                            \n 
                                                            \n$ pass insert example.org\n
                                                            \n

                                                            Enter the password at the prompt, and then again to confirm.

                                                            \n

                                                            Most websites require more than just a password, and so pass\n can manage additional data, like username, email, and any other\n field.

                                                            \n

                                                            To add extra data to a password file, use pass edit\n followed by the URL or string you saved the password as:

                                                            \n 
                                                            \n$ pass edit example.org\n
                                                            \n

                                                            The first line of a password file must be the password itself.

                                                            \n

                                                            After that first line, however, you can add any additional data\n you want, in the format of the field name followed by a colon and\n then the value.

                                                            \n

                                                            For example, to save tux as the value of the username\n field on a website:

                                                            \n 
                                                            \nmyFakePassword123\n\nusername: tux\n
                                                            \n

                                                            Some websites use an email address instead of a username:

                                                            \n 
                                                            \nmyFakePassword123\n\nemail: tux@example.com\n
                                                            \n

                                                            A password file can contain any data you want, so you can also\n add important notes or one-time recovery codes, and anything else\n you might find useful:

                                                            \n 
                                                            \nmyFake;_;Password123\n\nemail: tux@example.com\n\nrecovery email: tux@example.org\n\nrecovery code: 03a5-1992-ee12-238c\n\nnote: This is your personal account, use company SSO at work\n

                                                            List passwords

                                                            \n 
                                                            \n$ pass list\n\nPassword Store\n\n├── example.com\n\n├── example.org\n

                                                            You can also search your password store:

                                                            Integrating your password\n store

                                                            \n

                                                            Your password store is perfectly usable from a terminal, but\n that's not the only way to use it.

                                                            \n

                                                            Using extensions, you can use pass as your web\n browser's password manager.

                                                            \n

                                                            There are several different applications that provide a bridge\n between pass and your browser.

                                                            \n

                                                            Most are listed in the CompatibleClients\n section of passwordstore.org.

                                                            \n

                                                            I use PassFF,\n which provides a Firefox\n extension.

                                                            \n

                                                            For browsers based on Chromium, you can use Browserpass\n with the Browserpass\n extension.

                                                            \n

                                                            In both cases, the browser extension requires a \"host\n application\", or a background bridge service to allow your browser\n to access the encrypted data in your password store.

                                                            \n

                                                            For PassFF, download the install script:

                                                            \n 
                                                            \n$ wget https://codeberg.org/PassFF/passff-host/releases/download/latest/install_host_app.sh\n
                                                            \n

                                                            Review the script to confirm that it's just installing the host\n application, and then run it:

                                                            \n 
                                                            \n$ bash ./install_host_app.sh firefox\n\nPython 3 executable located at /usr/bin/python3\n\nPass executable located at /usr/bin/pass\n\nInstalling Firefox host config\n\nNative messaging host for Firefox has been installed to /home/tux/.mozilla/native-messaging-hosts.\n
                                                            \n

                                                            Install the browser extension, and then restart your browser.

                                                            \n

                                                            When you navigate to a URL with an file in your password store, a\n pass icon appears in the relevant fields.

                                                            \n

                                                            Click the icon to complete the form.

                                                            \n

                                                            Alternately, a pass icon appears in your browser's\n extension tray, providing a menu for direct interaction with many\n pass functions (such as copying data directly to your\n system clipboard, or auto-filling only a specific field, and so\n on.)

                                                            \n

                                                            Password management like UNIX

                                                            \n

                                                            The pass command is extensible, and there are some\n great add-ons for it.

                                                            \n

                                                            Here are some of my favourites:

                                                            You can sync your password stores between different machines\n using rsync or syncthing, or even backup the store to cloud\n storage.

So now we will take a look at\n these remaining novels.

Imagine the antenna is at the\n centre of a sphere, the signal strength at the surface of the\n sphere is equal at all points. The gain of an isotropic antenna is\n defined as 1, meaning:

                                                            The simplest practical antenna is a half wave dipole antenna,\n where each of the two legs is a quarter wave length long. The feed\n is at the centre, and the two legs are generally horizontal, and\n aligned away from the feed point 180 degrees apart. The dipole\n antenna exhibits gain perpendicular to the legs. The maximum gain\n is 1.64 times the isotropic antenna - a gain of approximately\n 2.15dBi. The gain off the ends of the dipole is much lower - the\n total power radiated by the antenna can not exceed the power being\n input, so if there is more radiation (gain) in one direction,\n there must be a corresponding reduction in a different direction.\n So:

                                                            ERP and EIRP are both used to indicate the power achieved using\n an antenna.ERP compares the antenna performance with a dipole, and\n EIRP compares the performance with an isotropic antenna. So, the\n ERP is the power which would need to be fed into a dipole antenna,\n to get the same effect in the direction your antenna is pointing.\n EIRP is the power required for an isotropic antenna to gain\n equivalence.

If I attach a Yagi-Uda antenna with a\n gain of 10dB, the ERP is 21.77 dB. Using the formula\n above, from this number you can calculate that this is the\n equivalent of 150.3142 Watts ERP. To understand the EIRP, we need\n to add 2.15 to the 21.77 dB value, giving 23.92 dB EIRP.\n Again, converting to actual power gives 246.515 Watts EIRP.

You can set your\n transmitter to output sufficient power to overcome any feed line\n losses, and present up to the power permitted to the antenna. A\n good antenna can then be used to get the transmitted power out\n and across the world. For feedline loses, the value is given in\n dB per 10 metres. For example, RG58 is 2dB / 10 metres (at\n 100MHz - choose the right feeder coax for your target\n frequency!). If you have 15 metres, then you will have 3 dB\n feeder loss, so half of your transmitter power will be lost in\n the feed line. If you know this and your transmitter can output\n more, then you can increase the transmitter power accordingly.\n So for 25W at the transmitter, with 3dB loss in the feeder, you\n can set the output to 50W.\n

So, with our example\n above, if we have 11.77 dB of output power, then -1 dB insertion\n loss for a bandpass filter, -3 dB loss for the feeder, and 5dB\n gain on the antenna, the overall ERP is 12.77 dB. You can convert\n this back to Watts, to get 18.92W ERP.

                                                            \n Isaac Asimov is best known for two series, the Foundation series\n and the Robot series, and he eventually tied them together. But he\n also wrote some stand-alone novels that are quite good, and I want\n to discuss them here. They are The End Of Eternity, The Gods\n Themselves, and Nemesis.

                                                            \nYou could fix it by modifying the \ngrep\n arguments and add additional searches looking for \nenclosure\n. The problem with that approach is that you'll forever and a day be chasing issues when someone changes something.

                                                            \n

                                                            \nSo the approach is officially \"Grand\", but it's a very likely to break if you're not babysitting it.

                                                            \nI recommend never parsing \nstructured documents\n, like xml or json with grep.

                                                            \n

                                                            \nYou should use dedicated parsers that understands the document markup, and can intelligently address parts of it.

                                                            \n

                                                            \nAlways refer to examples and specification

                                                            \n

                                                            \nA specification is just a set of rules that tell you how the document is formatted.

                                                            \n

                                                            \nThere is a danger in just looking at example files, and not reading the specifications. I had a situation once where a software developer raised a bug as the files didn't begin with \nken-test-\n followed by a \nuuid\n. They were surprised when the supplied files did not follow this convention as per the examples. Suffice to say that was rejected.

                                                            \n

                                                            \nFor us there are the rules from the \nRSS specification\n itself, but as it's a XML file there are \nXML Specifications\n. While the RSS spec is short, the XML is not, so people tend to use dedicated libraries to parse XML. Using a dedicated tool like \nxmlstarlet\n will allow us to mostly ignore the details of XML.

                                                            \nThe specification goes on to say \"At the top level, a RSS document is a element, with a mandatory attribute called version, that specifies the version of RSS that the document conforms to. If it conforms to this specification, the version attribute must be 2.0.\" And sure enough then the second line show that it's a RSS file.

                                                            Out of nowhere, my Firefox browser on my Mac mini started\n automatically adding every page I visited to my bookmarks.

And guess\n what? The source of my trouble turned out to be an 4 SVG files\n hiding malicious code.

They can secretly\n carry malware. In my case those were the files, a logos of\n reputable delivery companies like deliveroo and JustEat which I\n have downloaded while I was updating a website for my client.\n Today, we’re breaking down how SVG files are being weaponized, why\n they’re so effective, and how to protect yourself.

                                                            \nKevie was using a Bash pipeline to find the latest episode in an RSS\nfeed, and download it. He used \ngrep\n to parse the XML of the\nfeed.

                                                            \n\n

The same applies to other complex formats\nsuch as HTML, YAML and JSON.

It starts by defining a\n\nwhile\n loop, but the data which the \nread\n\ncommand receives comes from a \nprocess substitution\n of the form\n\n'<(statements)'\n (see the \n\nprocess\nsubstitution section\n of \"hpr2045 :: Some other Bash tips\"\n).

This is from Ken's original code. Each\nline is read into the variable \nitem\n, and the first element\n(before the semicolon) is extracted with the Bash expression\n\n\"${item%;*}\"\n. Parameter manipulation expressions were\nintroduced in \nHPR show\n1648\n. See the full notes section \nRemove\nmatching suffix pattern\n for this one.

                                                              \nThe \necho\n which generates the list of podcast URLs\nprefixed with an ISO time stamp uses \n';'\n as the delimiter\nwhere Ken used a \ntab\n character. I assume this was done for\nthe benefit of either the following \nsort\n or the\n\nawk\n script. It's not needed for \nsort\n since it\nsorts the line as-is and doesn't use fields. My version doesn't use\n\nawk\n.

                                                              \nRather than using \nawk\n I use \ncut\n to\nremove the time stamp from the front of each line, returning the second\nfield delimited by the semicolon. The result of this will be the URL for\n\nwget\n to download. In this case \nwget\n receives\nthe URL on standard input (\nSTDIN\n), and the\n\n--input-file=-\n option tells it to use that information for\nthe download.

                                                            \nI might have replaced the \nhead\n and \ncut\n with\na \nsed\n expression, such as the following as the last\nline:

                                                            \n\n

                                                            \n\n

                                                            \nHere, the \nsed\n expression operates on the first line from\nthe \nsort\n, where it removes everything from the start of the\nline to the semicolon. The expression then causes \nsed\n to\nquit, so that only the edited first line is passed to\n\nwget\n.

                                                              \nAn optional directory to look for the file. If this is omitted,\nthen the current directory will be used.

Since Bash glob pattern searches will return the search\npattern when they fail, it was necessary to use the\n\nnullglob\n (see references) option to prevent this, turning\nit on before the search and off afterwards.

                                                            \n\n

                                                            \nThis technique was replaced later with a pipeline using the\n\nfind\n command.

                                                            \n\n

                                                            \nThe function is in the file \nnewest_matching_file_1.sh\n,\nand it's loaded (\"sourced\", or declared) like this:

I keep this script in my \n~/bin\n directory, so it\ncan be invoked just by typing its name. I also maintain a symlink called\n\nnmf\n to save typing!

                                                            \nIn regular expressions \n'.*'\n means \"any character zero or\nmore times\". The \n'.'\n in \n'.png'\n is escaped\nbecause we need an actual dot character.

                                                            \nThe approach in both cases is fairly simple. Files matching a pattern\nare accumulated, in the Bash case including the modification time. The\nfiles are sorted by modification time and the one with the lowest time\nis the answer. The Bash version has to remove the modification time\nbefore printing.

                                                            \nThis algorithm could be written in many ways. I will probably try\nrewriting it in other languages in the future, to see which one I think\nis best.

                                                            In this episode, I talk about how I use Newsboat and Podboat for a\ncouple of tasks.

This only give an internal description, as the Main title\nis determined by the RSS feed itself. This can be manually set, for\nexample, in the HPR Future feed. The default feed title is the same as\nthe feed for two weeks. To set manually, us a tilde ~\nbefore the Feed Title shown in this example. Tags follow the Feed Title,\ntyped in parentheses and with no spaces. Multiple tags can be used\nhere.

                                                            • Replace the /r/commandline with /r/commandline.rss

                                                            \n
                                                            \n

                                                            Lemmy is part of the Fediverse, and became popular after the June\n2023 controversy involving charging excessive money for Reddit’s\nAPI.
                                                            \nThis in turn, caused third party Reddit apps to be no longer viable.

                                                            Where %h is the Hostname, and %n is the Podcast name

                                                            \n

                                                            The file name is formatted in the following way

                                                            \n

                                                            Where %n is the podcast name, %t is the podcast title and %u\nindicates the file extension

                                                            Finally, there is a custom line for podlist-format which\nfor podcast purposes I won’t list out.

                                                            \nin order to pause a show with the bluetooth button on an earbud.

                                                            Then enable the service with\nsystemctl --user enable mpris-proxy.service and\nsystemctl --user start mpris-proxy.service

                                                            \n Hi. My name is Moss Bliss, and this is Hacker Public Radio. This\n is my 3rd HPR solo podcast, and you can also hear me on mintCast\n and Full Circle Weekly News most weeks.

                                                            \n

                                                            \n I watch TV via streaming on a Lenovo\n ThinkCentre M700 Tiny. I change streams and services using a\n wireless keyboard, from my recliner across the room. For a couple\n years, I was using a Logitech\n K400r, and it worked pretty well. Good keys, nice touchpad,\n a couple of extra features. It was kind of flimsy though, with\n lots of flex and keys popping off from time to time -- not so much\n of a problem as they popped back on well -- and then the plastic\n on-off slider just wore out. It had a raised strip on the plastic\n slider which served as something to grab with a nail, and it just\n eventually wore down. So I went looking for something perhaps a\n bit sturdier.

                                                            \n

                                                            \n

                                                            \n What I found was a Rii Model K22.\n The box had some different numbers in addition to that, and the\n label on the keyboard also had other numbers, but the best way to\n find it is to look for the K22. It was a solid, mostly metal,\n keyboard, so I bought it. No flex to speak of, and the keys are\n made to not pop off.

                                                            \n

                                                            \n There are some caveats. The volume up-down and mute buttons are\n part of the touchpad, not physical buttons, and are not lighted.\n In a dark room, with a black keyboard and touchpad, it can be easy\n to hit the wrong area of the touchpad. Also, I have yet to get the\n scroll feature -- supposedly the right side of the touchpad -- to\n work properly, but most of the time I can scroll with two fingers\n on the touchpad. Also, and I have no clue why, it sometimes brings\n up a menu I've never seen before getting this keyboard. Yes, it's\n pretty easy to make it go away, but still...

                                                            \n Unlike the K400r, the K22 has a rechargeable battery built in, and\n charges via USB-C. Also, the touchpad is significantly larger than\n that of the K400r. I have had no problems with touchpad's\n responsiveness, other than the issues already mentioned. I'm not\n really very good with touchpads, so perhaps I just haven't learned\n the features.

The\n cheaper model has fewer buttons and a few cutbacks on design\n features. The K400r has a 4.2 star rating, with 67% 5-star and 16%\n 4-star. The Amazon AI reports, \"Customers find the keyboard\n functional and easy to use. They appreciate its responsive keys\n and convenient setup. Many find it a good value for the price,\n lightweight, and convenient to use from the couch. However,\n opinions differ on the size and touchpad responsiveness.\" The\n Logitech is wifi only, but it does come with the ubiquitous\n Logitech wifi dongle.

I'm sure there are use\n cases where the Rii K22 would not be the best fit, but for my use,\n it is a huge step up from the K400r. The build quality and\n materials alone make it perfect for my use, where I sit in my\n recliner and use it to maneuver my browser and streams, and then\n toss it in the corner when I'm done.

                                                            \nThanks Marty, today I'm going to improvise jazz piano on a song inspired by Immanuel Kant.

                                                            \n

                                                            \nNow Immanuel Kant was an influential philosopher back in the 18th century and he remains influential today. Kant created a dichotomy between phenomenon and noumena where phenomenon applies to things we can perceive with the senses and noumena are things that cannot be perceived. So I wrote this song called \"Noumenolgy\" about the study of things that cannot be perceived.

                                                            \n

                                                            \nAt first I thought this would be an ideal academic tenure, I mean, who could prove you wrong? But further thought led me to many scientists who deal with noumena on a daily basis.

                                                            \n

                                                            \nTake cosmology for instance, the study of the origins of the universe. Cosmologists have come up with the idea of the big bang, something that happened about 14 billion years ago. They check how fast the universe is expanding to come up with a number like that. And they keep building bigger and bigger telescopes because the farther away something is the longer it took for it's light to get to us which means we're really looking back into the past when we look at distant galaxies.

                                                            \n

                                                            \nWell, the big bang is noumenal. I mean, nobody's going to actually perceive it. So you could say that some cosmologists are, in fact, noumenologists.

                                                            \n

                                                            \nOr take particle physics. String theory, where we look at the stuff that makes protons and electrons, started as a mathematical exercise without proof in the real world. Definitely noumenologically inclined.

                                                            \n

                                                            \nBut those particle physicists kept building bigger and bigger cyclotrons banging atoms together to see what escaped and they started detecting the mathematically predicted sub-particles. I read last week that they discovered a particle that has mass going in one direction and no mass going in the other. Now, how does that work?

                                                            \n

                                                            \nMoving on from philosophy, cosmology, and physics to noumena that actually affect ordinary people. Songwriters have written more songs about it than any other subject. Stories about it finance the publishing industry allowing them to publish books on philosophy and cosmology. And Jesus preached about it as his core message. Of course, I'm talking about love, something everyone experiences that has no phenomenal existence.

                                                            \n

                                                            \nYou can't see it. You can't touch it. What is love? remains a valid philosophical question. So there we are. Back to Kant.

                                                            \n

                                                            \nOn the song \"Noumenology\" I scat sing with a bebop and a doowop replacing actual words. So I got to thinking this morning, maybe I should write a lyric? Maybe about a cosmologist and a physicist who fall in love. Or even better a cosmologist and a physicist who bond over their shared their love for noumenology.

                                                            \n

                                                            \nWhich brings us to the big question. Just what is up with Hairy Larry's brain and how does he come up with this stuff? I'm going to reveal my secret. Sometimes it's dreams.

I'll defend one other, that can be as imprecise as every other, but, I feel, brings the concept closer to the general meaning of the word: \"A hacker is someone in pursuit of efficiency and knowledge, be it in some specific field or maybe in anything that can be known\".

It's targeted to what achieve emotional, relevant responses to the person, that has to do with purpose. Everyone has a purpose, and we can see purpose as a matrix.

                                                            \nWhere is the happy hacker located? Let's remember, a hacker is someone that seeks out meaning. The definition proposed in this show is: \"A hacker is someone in pursuit of efficiency and knowledge\". So, the blessed hacer is the one on the top of the matrix of purpose: it is someone that has a purpose that is relevant to him. He does not need success, he needs a reason to pursue it, even though the results are not always 100% dependent on him.

                                                            \n

                                                            \nIf someone gives him (or her, of course) one ideia of purpose, and he adopts it as his personal search, he can achieve great success  be it on any area you can imagine. But, if it is not of his heart, he will end up being less than he could be, feeling unsuccessful. Because, a hacker is not searching for efficiency on the void: he needs his brain inputted in what has relevance on this own, intimate understanding of the universe. And this is why \"a hacker is someone in pursuit of knowledge and efficiency\". Both together, conveying as a meaning, a meaning the hacker dedicates himself to, and that makes him happy, even in days, months or years without observable results.

They do not try to use their brains to maximum learning, to have transcending conversations, to, eventually, teaching other people, formally or informally.

It's not a matter of what you like more, or how you prefer to do or not to do things. It's an entirely differen mind, more sensitive in some parts, more out-of-this-world in some others.

                                                            Today we talk with Margreet Pakkert, who was kind enough to record an interview during the Flevoland 2025 Field Work Archaeology Open Day . The students were supervised as they document a Dutch Waterschip . This is a type of fishing vessel that was common in the Zuiderzee before it was reclaimed to form the province of Flevoland . As fish were caught they were kept alive in two chambers in the boat that were open to the sea¸ allowing the fishermen to deliver the freshest of fish to their market .

                                                            As the water table in Flevoland is lowering, the shipwreck will soon rot away. So the team are out teaching students the craft of documenting the find and preserving what is unique. The ship itself sank between 1520 and 1530.

                                                            Search in the search bar for \"contacts\" and when displayed, click\n the 'Activate' button of the \"contacts\" app.

                                                            \n

                                                            When done, the same menu now contains: Discuss, To-do, contacts,\n Project, Email Marketing, Surveys, Employees

                                                            \n

                                                            and the earlier mentioned Apps and Settings.

                                                            \n

                                                            Go back to 'Apps' and Activate the \"Sales\" app. This will also\n install the \"Invoicing\" app.

                                                            \n

                                                            Time to start playing around.

                                                            \n

                                                            Some tech stuff, interesting locations

                                                            \n

                                                            ===============

                                                            \n

                                                            /etc/odoo/odoo.conf

                                                            \n

                                                            Here you can add additional addons later:\n /var/lib/odoo/.local/share/Odoo/addons/18.0/

                                                            \n

                                                            Here are all files uploaded to Odoo: find\n /var/lib/odoo/.local/share/Odoo/filestore/

                                                            \n

                                                            This is where user sessions are administrated: find\n /var/lib/odoo/.local/share/Odoo/sessions/

                                                            \n

                                                            And these are the main locations where the Odoo program can be\n found.

In this show Beni educates Andrew the \nLuddite\n and explains why moving from IPv4 to IPv6 is a good idea. They also explore how IPv6 can be used in a world where ISPs and devices do not all support it and what tools, tips and tricks are available during this rather long transitional phase to the newish (like 30 years old, a blink of an eye in IT) protocol.

                                                            \nHello, this is Archer72 for Hacker Public Radio.

                                                            \n\n

                                                            \nIn episode, it seems that AI is a trap. This over-arching\ngeneralization is my opinion and may not reflect the opinions of\nHPR.

                                                            \n\n

                                                            \nSo the back story to this is that I was listening to the 26 hour\nHacker Public Radio New Year’s show, and the discussion came up in the\n\nTech and Coffee Telegram\nChannel\n My Resolution was to stop using ChatGPT for an AI chat bot,\nwith the implication being to not using AI at all, but instead, to use\n\nDuckduckgo\n and\n\nBrave\nSearch\n

                                                            \n\n

                                                            \nProbably less than a week or two later, I was trying to figure out\nsomething, and figured that I’d use the easy way and use \nClaude.ai\n , which is\nactually pretty good if you have short and concise questions. I’ve found\nthat if you have a long drawn-out question, it is better to do a Google\nor \nDuck search\n\nand document your results.
                                                            \n\nI document in Vim, but you can use whatever is best.

                                                            \n\n

                                                            \nThis way you can clearly show what works and doesn’t work and refer\nto what you find later, instead of relying on an online service. And\nsometimes, depending on the AI bot you use, exporting is not very\nstraightforward. With the exception of \nDuck.ai\n, that has a button for a quick share of a\ntext file. Then you share it to your self somewhere else like in \nProton\nmail\n

                                                            \n\n

                                                            \nWell… Over the past weekend, I was just making a quick upload button\nto my own server. The previous weekend, I got HTTPS working. This was\njust from following the guide on the \nLet’s Encrypt -\nDocumentation\n and \nEFF Certbot instruction -\nApache2\n websites. At least that time, instead of using the AI bot, I\njust followed clear documentation.

                                                            \n\n

                                                            \nSee, the thing about going right to the \nDebian Wiki\n or\nthe \nArch Wiki\n\nis that users and developer have already documented plenty. I figured\nout that part of the hacker method is not to take the ‘easy’ way, but to\ndocument out what you are trying to learn.

                                                            \n\n

                                                            \nSo this past weekend, I was trying to learn something about that\nupload form, and I probably took longer going back and forth with the AI\nbot than If I had taken the time to search the documentation. And even\nif it did take longer with the documentation, I would have learned\nsomething else and created a Markdown document of my own. There is a\ntool I use once in a while, which is part of the \nDuckduckgo\n search,\ncalled \nSearch Assist\n

                                                            \n\n

                                                            \nThis can be good, because a have a horrible memory. If there is\nsomething small that I can’t remember how to do, I let \nDuck.ai\n take care of it. But recently, I have turned\noff the option where it says to sometimes show \nSearch Assist\n, but instead only when it is on\ndemand. That way I won’t be tempted to go down a rabbit hole in order to\nfind what I am looking for. Instead base what I am looking for on\nstandard tools.

                                                            \n\n

                                                            \nSo Yes, AI is a trap, but is also useful for certain things. But if\nyou are careful how you use it, it’s not always a bad thing.

                                                            \n\n

                                                            \nI've found HPR about a year ago and wanted to record a show since. But life is busy. I'm trying it out, in a supermarket parking lot in my car. This is my second attempt, so we'll see how it works.

                                                            \nHow I got into tech? In a way I've kind of always been there. At least since I was a child. The story that I like to tell is when I was about 4 years old my cousing launched me Mortal Kombat on his Amiga computer and I got interested. That's my oldest tech related memory. As a kid I've mostly played video games. Mostly on clones of old 8-bit consoles like Atari 2600 or NES, later some unspecified models of Commodore and Schneider computers. I don't even remember what exact models they were. Got my first PC at about 10 years old, it was an Intel 486SX, 12 MB RAM, 850 MB HDD, running Windows 95. Still mostly playing games on the computer but, as it was running Windows, as you maybe know, with Windows come problems. Sometimes user-induced, but not always. Spoiler, it's been over 25 years and this trend continues.

                                                            \n

                                                            \nAround the same time my sister went to high school and got a Turbo Pascal textbook. This is what really got me interested in programming and that's when my interests and career in software development begun. Since that time I had a very good idea what I want to do in life. I just knew I wanted to work with computers, primarily doing software engineering. I went to a technical university, Wrocław University of Science and Technology. And there I got interested in other computer related things like networking and I also got into digital and analog electronics. Just because I really wanted to go that one level deeper, to learn about how computers work, and electronics in general.

                                                            \nI also have other interests, but tech and non-tech related, like for example science fiction literature and I would like to record some shows about those in the future. We shall see.

                                                            \nThere is one specific story I want to tell, but I think I will save it for October. Why October? Because it is a workplace horror story about... Windows. Well, not really a horror story story, but it was really bizarre and can be described as such. In the meantime I don't want to promise anything. But maybe I will record a show about what I am currently doing at work, which is the topic of audit trail in software applications. But I am chaotic and may do something entirely different. We shall see.

                                                            \nI think that's all I want to say today. I would really appreciate if you left some feedback. Was the audio OK, is my English enough, did I speak too fast? English is not my first language and I've noticed over the years that I really tend to speak too fast when using English. And that's it, thank you for listening. Hopefully we'll hear in the future from me.

                                                              \n This is a good time to discuss the Victory types in Civ 5. We have\n talked about choosing appropriate strategies and that mostly has\n to do with what kind of Victory you are aiming for. Now you can\n change the objective as the game goes on, so if you realize you\n can’t win your original Victory type, you can switch to another.\n But success is a lot easier if you make the right choices early\n on.

                                                              \n

                                                              • \n Domination – To win this, you must keep possession of your own\n original capital, and capture everyone else’s original capital.\n Original capital is the first city founded by each Empire. It\n can never be destroyed, but can be captured. Once the original\n capital city of an Empire is captured, another city will become\n the \n current \n capital, but capturing that does not count towards victory, and\n a current capital can be destroyed.
                                                                • \n
                                                              • \n Science – To win this, build and launch a spaceship to Alpha\n Centauri. To build a spaceship requires technologies at the end\n of the Technology tree, but you don’t have to actually research\n every possible technology to do this. You build the parts in\n your various cities, and assemble them in your Capital. Once you\n have assembled all the parts, the spaceship will automatically\n launch and you win the game.
                                                                • \n
                                                              • \n Cultural – This depends on your culture compared to the other\n Empires, and involves the Tourism mechanic. If you attract\n tourists from another Empire, your culture will become more\n dominant over theirs. There are 6 levels for your Empire\n vis-a-vis the others: Unknown, Exotic, Familiar, Popular,\n Influential, and Dominant. These are defined by the amount of\n tourism you receive from an Empire compared with their own\n production of Culture. If the tourism you receive is at least\n equal to their own Culture production, you are Influential. And\n to get Culture victory you have to be at least Influential with\n every other Empire still in the game. The basic source of\n tourism comes from Great Works of Art, and Artifacts. Great\n Works of Art are produced by Great Artists, and Artifacts are\n dug up by your Archeologists once you discover this. Your own\n Culture production both defends against tourism of other Empires\n (i.e. your own citizens would rather enjoy your culture than\n travel to other Empires), and helps to produce the Great Works\n of Art. This victory type and the Tourism Mechanic is one of the\n innovations in Civ 5 , and carries over and is developed further\n in Civ 6.
                                                                • \n
                                                              • \n Diplomatic – To win this, you have to voted in as World Leader\n in the United Nations. You can gain votes in several ways.\n First, you can liberate the conquered capital of another Empire\n and return it to them. That will guarantee that they will vote\n for you in the United Nations. Or, and this is most common, you\n can ally with City-States and get their vote in the UN. Finally,\n if a City-State has been previously conquered by another Empire,\n you can liberate it and they will vote for you in the UN. Once\n the UN is achieved, votes take place every 20 turns, so if you\n fall short on one try, you can try to line up more votes for the\n next try, which usually means allying with a few more\n City-States.
                                                                • \n
                                                              • \n Time – If no one has won by the above means, the Empire with the\n highest score when time runs out will win. In a Standard game,\n that is in 2050 AD, and is turn 500. But note that turn 500 is\n not a turn when you can make a play. Your last chance to\n actually do anything is turn 499.
                                                                • \n

                                                              \n Terrain

                                                              \n Civilization V changed the game board from squares to hexes, which\n was the first big change. But another change makes terrain even\n more important in Civ V, and that is that you can only have one\n unit per tile. The giant death stacks of units that you could\n employ in Civ III and Civ IV are now gone. That means that any\n military campaign will mostly be fought on a variety of tiles.\n Most of this we will discuss later when we look at the military\n and how to fight wars, but knowing how terrain affects your units\n in terms of strength and mobility will be a big part of that. So\n first we need to know what the Terrain Types are. Of course, the\n other reason we need to know this is in terms of where to settle,\n where to farm, where to mine, and so on. And special resources are\n a modifier, but first we’ll look at the Terrain Types by\n themselves. They can be analyzed in terms of their Base\n Production, i.e., what they will produce without any improvements\n such as farms and mines, Movement Cost, i.e. how many movement\n points it takes to move into the Tile, and Defensive Bonus, i.e.\n how the strength of your units is modified if they are in combat.

Note that the Base\n Production for tiles with Forests will be 1 Food and 1\n Production regardless of the underlying Terrain Type. But\n Forests can be cleared by Workers once Mining is discovered.
                                                                • \n

They are lighter in color than\n deep ocean tiles. Coast tiles can be traveled on by early water\n units which cannot travel on the deeper ocean tiles. Coast tiles\n produce one gold each.

This will reduce food by\n 3, production by 3, and gold by 3. Movement cost is 2. In\n practice this will mean the tile produces nothing. A Worker unit\n can clean this up, but it will take time. So until that happens,\n you should look for opportunities to move your citizen into some\n other occupation until it is cleaned up. And you have to clean\n it up before building or restoring any improvements.

                                                              \n Admittedly, this is a lot of detail to take in, but there are a\n few basic rules you might want to keep in mind. First, you don’t\n want to settles cities where there are lots of Desert, Tundra, or\n Snow tiles. One or two Tundra tiles are OK if there are other\n positive features, like access to a luxury resource, but Desert\n and Snow tiles are completely useless. Again if there are lots of\n desirable tiles available, having one or two Desert or Snow is not\n problem, since in most cases you never will work all of the tiles\n in most cities. But look for the good tiles. Similarly, Mountain\n tiles are not generally useful, however if you are going for a\n Science victory they can be handy if you settle a city immediately\n adjacent to a mountain, since that will let you build an\n Observatory in the city. Observatories cost zero maintenance and\n add 50% to the science output of the city, making them very\n valuable. Mountains are also handy as barriers to keep away your\n enemies. Jungle tiles can also cause disease outbreaks, but\n clearing the jungle from the tile will put a stop to that. I will\n always clear away any jungle or Marsh tiles within my cities.\n Defensive bonuses are also important, but that is better covered\n when we get to warfare.

                                                              Hello, this is your host, Archer72 for another episode of\nHacker Public Radio.

                                                              \n

                                                              In this episode, I continue to fall for the AI trap.

                                                              \n

                                                              Here I was, minding my own business, when I was bothered by\nthe icon only showing a generic icon for the Beeper app.

                                                              \n

                                                              Now, I'm not saying that Duck.ai is not useful, but be\nvery careful what you ask for.

                                                              \n

                                                              It was probably a combination of the early morning, and not\nreading completely through the AI suggestions, but I ended\nup losing all icons on the Gnome desktop except for a few\nlike Firefox. I won't leave the problematic command so I\ndon't trip up the listener, but it involved updating a\ndesktop database. This in turn left a dash or blank where\nthe icons should be.

                                                              \n

                                                              If that wasn't bad enough, it was suggested to reset Gnome\nsettings, and nothing was as it seemed before. Things that\nI had taken for granted were not there. You forget what\ncustom settings are there when mistakes like this are made.

                                                              \n

                                                              So the short answer is that the icons directory, located on\nmy Debian system should be located in

                                                              \n

                                                              .local/share/icons.

                                                              \n

                                                              Instead it was in a sub-directory

                                                              \n

                                                              .local/share/icons/icons

                                                              \n

                                                              Correcting the directory location solved everything, but I\nwas still left to reset my custom Gnome keybindings.

                                                              \n

                                                              I used this because I am a Vim user, and this feels more\nnatural when I need to hit Escape to change modes.

And I have had a love for doing so ever since. Over the last few years, I have built several Arduino based gadgets on different platforms, including a couple which run on breadboards sitting beside me on my desk (I will share more about one of those later).   \n

Nothing catastrophic, just one of those dull throbs\n that tells you something's going on in there that could turn nasty\n if ignored. The receptionist calls my name, and I walk into Dr.\n ChatControl's office.

                                                              \n

Toothaches\n are a serious problem. Did you know that in 2023 alone, at least\n 101,988 people in Europe experienced dental pain? That's over 60%\n of all global dental complaints traced to this region.\"

                                                              \n He hands me a pamphlet titled \n Safety-by-Design for Oral Health\n . \"From now on, you'll need to implement parental controls on your\n diet. Every candy will come with an age verification wrapper and\n user reporting mechanisms. so your teeth can flag potential\n problems, and verify your age before consuming any hard foods.\"

                                                              \n \"Now,\" Dr. ChatControl continues, \"since your mitigation measures\n haven't been implemented yet because you just got here - I'm\n authorized to issue a detection order.\" He holds up an\n official-looking document with a judge's signature. \"This allows\n me to scan not just the tooth that hurts, but your entire mouth.\n Also your sinuses. And your lymph nodes. And, just to be thorough,\n everyone in the waiting room.\"

                                                              \n \"It's targeted,\" he assures me. \"We're only scanning high-risk\n areas—which, according to our independent EU Dental Centre, is\n every tooth, every patient, all the time.\"

                                                              \n \"But here's the clever part,\" Dr. ChatControl says, pulling out\n what looks like a tiny sander strapped to an airbrush.

So we need to\n replace the enamel with an optimized layer that perfectly protects\n against currently known sugars and acids but allows our government\n approved detection equipment to inspect the content of your\n teeth.\"

                                                              \n

                                                              \n I' flabberghasted. \"You want to weaken my enamel?\"

                                                              \n \"Only slightly!\" he said cheerfully. \"Just enough so that our\n scanner can monitor what's happening inside your teeth at all\n times. Don't worry,the new enamel will still protect you from\n everything else.\"

                                                              \n

                                                              \n \"How's that possible if you can penetrate it?\", I continue, still\n cautious.

                                                              \n

                                                              \n \"Well, factory approved candies, for example,\" he says. \"Reputable\n candy manufacturers have agreed to respect the adapted enamel and\n not penetrate it. They've signed a treaty to use optimized\n sugars.\"

                                                              \n

                                                              \n \"Ah,\" he said, adjusting his glasses. \"Well, those are obviously\n illegal! Those criminals don't tend to honor treaties. So yes, the\n adapted enamel will make your teeth more vulnerable to\n unauthorized cavity formation, bacterial attacks, and anyone who\n wants to exploit the fact that your natural protection has been\n replaced with a see-through version.\"

                                                              \n

                                                              \n \"So you're making my teeth less secure,\" I repeat.

                                                              \n

                                                              \n \"We're making them more observable,\" he corrects, with a slightly\n annoyed tone. \"There's a difference. Your teeth will still be\n protected, just not from us. Or hostile foreign candy shops. Or\n those criminal artisanal real-sugar-nuts. But you have no business\n there anyway. But they definitely protect against harms from\n law-abiding candy!\"

                                                              \n

                                                              \n \"But... Over 500 leading dentists signed a letter saying this\n would create massive vulnerabilities\", I point out.

                                                              \n

                                                              \n \"Those dentists aren't thinking about long term dental hygiene.\"\n Dr. ChatControl sighs dismissively. \"Besides, it's not a backdoor\n if we're replacing your front door with a tinted glass door given\n all our citizens are law abiding!\"

                                                              \n

                                                              \n His tone gets sterner if he continues: \"Let me say more, If you\n refuse to upgrade your enamel, we will consider you a risk of\n dental terrorism. This no longer is about only your teeth, you\n must know. If you choose to blatantly ignore your teeth, you are a\n threat to society!\"

Of course, I am no git expert by any means, but as it\nhas been said in comments Hacker Public Radio is my memory.

Suggested follow-ups are not good, prefer instead to talk to the AI, as a real conversation, to get confirmation, or contrast something you disagree with etc.

(They do not know what they are telling, nor understand the value of sources.) And you can expect different outputs for the same inputs. (They are not deterministic.)

But for the intellectual work, if you like to think, if you’re good on written expression, the LLM may get passable results in less time… at the price of removing from you the chance to dedicate yourself to the comprehension and production. \nSo\n, it’s not always a matter of producing like a king — effectiveness above all and everything —; it may be important to satisfy what you value as meaningful — learning, maybe; or feeling the satisfaction of the conclusion —, so that you can sustainably follow a routine that is not a pain on the eye (expression to mean something disgust).

These span \n\n28 MHz to 29.700 MHz. \n\nI had the antenna connected to a 10 meter transceiver to listen in on the radio traffic. Yes, I will include pictures of the antenna in the show notes. \n

Continuous wave, is abbreviated CW in amateur radio circles, and it stands for morse code signals transmitted over radio frequencies. The tones indicating dots and dashes of Morse code were clearly audible through the radio's speaker. \n

The term QSO the amateur radio term for radio conversations.  I also have no interest in digital modes (yet). I like the simplicity of voice and CW. There I am, back at Morse code again. \n

                                                              \n\nWhat if there was a way that I could transmit a signal in Morse code and get reliable feedback on signal propagation, without the need to try to reply to any responses? It would need to be an accurate, repeatable, properly structured and timed Morse code transmission, more than my training (at that point, or even this point) could accomplish. \n

This is the pilot episode of Hacks Poetic, a new spoken word series that explores the intersection between creative language and technical knowledge. The program offers a series of poetic writing containing thoughts and information on subjects of interest to computing and hacking enthusiasts. You will hear poems about robots, expanding rural connectivity, details about a notoriously difficult video game and much more hidden between the lines. It is my hope that encoding ideas this way will allow for a different kind of understanding and perhaps reach a new audience compared to more conventional formats on the subject. My name is Kirbotica and I'll be your guide through this unique digital journey of the mind. So sit back, relax and listen, and see if something you hear can spark new thoughts and ideas within you.

Dragon Ball was originally inspired by the classical\n 16th-century Chinese novel Journey to the West, combined with\n elements of Hong Kong martial arts films. Dragon Ball characters\n also use a variety of East Asian martial arts styles, including\n karate[1][2][3] and Wing Chun (kung fu).[2][3][4] The series\n follows the adventures of protagonist Son Goku from his childhood\n through adulthood as he trains in martial arts. He spends his\n childhood far from civilization until he meets a teenage girl\n named Bulma, who encourages him to join her quest in exploring the\n world in search of the seven orbs known as the Dragon Balls, which\n summon a wish-granting dragon when gathered. Along his journey,\n Goku makes several other friends, becomes a family man, discovers\n his alien heritage, and battles a wide variety of villains, many\n of whom also seek the Dragon Balls. \n https://en.wikipedia.org/wiki/Dragon_Ball\n

                                                              \n\nThat was me, tapping out \"CQ CQ\" in Morse code using the practice set I keep on my desk. This consists of a set of code paddles, connected to an Arduino Nano, which I built several years ago based what I learned watching \n\nCode Practice Oscillator; Aka: The Three Arduinos\n\non Jmhrvy1947's YouTube Channel, and based on the code from \n\nhis GitHub\n\n \n\nhttps://github.com/jmharvey1/ArduinoCPO\n\n. I did need to make modifications, both to support the Ardunio Nano on which I chose to run it, and for my own sanity, as the way that I learned to write code for Ardunio is very different. I focus on readability and flexibility. You can see these changes on \n\nmy own GitHub\n\n(\n\nhttps://github.com/jttrey3/PracticeOscillator/blob/main/PracticeOscillator.ino\n\n) \n

                                                              \n\n \n

                                                              \n

                                                              \n\nAnyway, I have been studying. I have been watching videos. I have been practicing. I might actually be learning some of this stuff. If you are interested in more details about the resources I am using, leave a comment for this episode, or drop me an email using the address in my profile, and I may record an episode about it. \n

                                                              \n

                                                              \n

                                                              \n\nThe result is that I have been learning. But also, the google and YouTube algorithms have been learning about me. And they have started to feed me more videos about Morse code. It is both helpful, and super creepy at the same time. \n

                                                              \n\nSo one day, when I opened YouTube, a title in my feed caught my eye. \"\n\nNEW CW OP USE THE REVERSE BEACON NETWORK TO IMPROVE YOUR CODE\n\n\". \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nI said to myself, \"Self, this could be interesting.\" I watched Keith's video and learned about the \n\nReverse Beacon Network\n\n.  According to their website, \"The Reverse Beacon Network (RBN) is a revolutionary new idea. Instead of beacons actively transmitting signals, the RBN is a network of stations listening to the bands and reporting what stations they hear, when and how well.\" \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nLet's pause for a second and discuss amateur radio beacons. These are stations which repeatedly broadcast their identity on dedicated frequencies. Other operators around the world, who hear a beacon, can evaluate the signal propagation between their station and the beacon location.  \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nThe RBN is just the opposite. Here, the station operator can transmit a test signal with their call sign, using CW or other digital modes. Then, they can look at the RBN website to see which RBN listening stations received their transmission, and even get a signal report. \n

                                                              \n\nOn the \n\nmain page\n\nof the RBN website, one can observe a world map with paths showing where signals were received, and where they originated based on the registered grid square of the originating call sign. The table displayed below the map reveals the sending and receiving call signs, their distance apart (In miles or kilometers), the frequency, the mode, the type of transmission, the signal to noise ratio, the speed of the transmission, and the time/date using UTC. \n

These receiving stations report what they receive as well as the signal strength back into the Reverse Beacon Network to be recorded and published over the internet. \n

                                                              \n\nDave Casler discussed the RBN back in 2016 on his YouTube video \n\nThe Ham Radio Reverse Beacon Network, AD#32\n\n. This gives very good detail of how the network works. \n

                                                              \n\nThis sounds like exactly what I have been looking for. All I need to do is come up with a way to reliably, accurately, and consistently transmit \"CQ CQ CQ TEST DE\" followed by my call sign three times at a constant 20 words per minute (WPM). If I can do this a few times, I can then check the RBN to see where I was received. By including the \"TEST\" string, recipients know that I do not wish to start a conversation. I can get accurate reporting of where my signal is going and how strong it is. \n\n \n

                                                              \n\nBut remember that my morse code skills are still inadequate. And my radios do not have \"Keyer memories\" like those which can be found in higher end transceivers like the Icom 7300, enabling programmed messages to be sent at the touch of a button.  \n

                                                              \n\nBut there is a fairly inexpensive solution to this problem. One which has been nagging at the back of my mind. Maybe, I could use the Cheap Yellow Display to effectively add \"Keyer memory\" to any of my radios by simply plugging it in to the code key input port. These stored messages could be transmitted by simply touching their specific icon on the touch screen. \n

It is a portable, programmable morse code \"Keyer memory\" which can be connected to any of my HF transceiver radios by simply plugging it in to the code key input port. Then I could transmit stored messages by simply touching their specific icon on the touch screen. \n

                                                              \n\nIn general, the paddle is two separate normally open switches. In the most common configuration, if an operator presses and releases the paddle on the right, a dash is sent. If the paddle on the right is held, a continuous series of dashes will be sent until that paddle is released. \n

                                                              \n

                                                              \n\nThe left paddle works similarly. If it is pressed and released, a single dot is sent. If it is pressed and held, a series of dots is sent until it is released. The function of these paddles can be swapped from left to right using the radio configuration. There is additional functionality which can be configured in some radios for when both paddles are pressed simultaneously, but I am not going to describe those here.   \n

                                                              \n\nThe paddle generally uses a 3.5mm stereo male phone connector with the sleeve being common. The tip of the phone connector is wired to the left paddle and ring of the connector is wired to the right paddle. Most modern radios have a built in keyer which can be configured for a paddle and will automatically transmit the dots or dashes at whichever speed is configured based on the paddle pressed. \n

This way, when the current source is stopped, the diode gives a path for the inductive kickback current to safely flow while the magnetic field dissipates. Explained in greater detail at \n\nhttps://inductive-kickback.com/2019/04/inductive-kickback-made-simple-to-grasp-easy-to-handle/\n\n  \n

I also want to be able to program each macro individually from the graphical user interface (GUI). \n

Most of the CYD resources I have been referencing recommend using Squareline Studio for GUI development on the CYD. Sadly, Squareline Studio is not open source. If any of you have experience with a good, open source alternative to Squareline Studio, please record a show to help the rest of us. Squareline does have a free trial and a free single user / single computer license, which I am using for this project. It will run on Windows, Linux, and Mac.\n\n \n

I would like to have a keyboard page where the user can type a custom message and send it. \n

I defined actions within Squareline, such that when the specific navigation button is pressed, it will change the button appearance to look like it has been pressed and will then scroll left or right to a specified screen. Actions were also valuable for the Speed (WPM) slider on the Config screen. When this slider is moved left and right, the GUI will change the actual number for WPM to the right of the slider. \n\n \n

And we will also discuss Morse code speed in a future episode in this series. The original code (As found on \n\nhttps://github.com/jmharvey1/ArduinoCPO\n\n )\n\n specified 12 words per minute (WPM) as the default speed, with buttons to increase or decrease this. However, I am practicing at 20 WPM. Every time I turn on the practice set, I need to turn up the speed and guess when I am close to 20. I went ahead and opened the PracticeOscilator project in Arduino IDE and updated the wpm variable to a value of 20. No, you will not see this change reflected in my own GitHub repo because:\n\n \n

I spent several days troubleshooting, using other Arduino devices, different USB ports, and different cables, all to no avail. If anyone has any recommendations, I am open to suggestions.\n\n \n

                                                              \n\nSo, I dug out my son's old Windows 10 PC and started again. I had to install the Arduino IDE, load all the necessary libraries, and my code from Github (Which I had to manually change once again, because I don't fully get git). Finally I was able to update the Arduino Nano with its new code, and it works perfectly.\n\n \n

                                                              \n\nTo review, my project is to build a portable morse code \"Keyer memory\" which can be connected to any of my amateur HF transceiver radios by simply plugging it in to the code key input port. This is based around an ESP32 platform which comes prepackaged on a yellow PC board with a color touchscreen display, WIFI, and Bluetooth. We fondly call this contraption the Cheap Yellow Display.   \n

                                                              \n\n \n

                                                              \n

                                                              \n\nSo far, I have defined the necessities, collected the required hardware, and failed miserably building the graphical user interface (GUI).  \n

                                                              \n

                                                              \n\nWhile I sort out the technical challenges getting my GUI code to play nicely with the CYD's touchscreen, it is important that we spend some time discussing Morse code itself, and the timing standards we will need to follow. \n

                                                              \n\nI am not going to dive too deeply into the history behind telegraphs and Morse code, but it is very interesting. If you want to learn more, Wikipedia has the origins and evolution written out quite nicely at \n\nhttps://en.wikipedia.org/wiki/Morse_code\n\n  \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nFor our purposes, we will fast forward from the year 1820 (When telegraphy began) all the way to 1865 when the International Telecommunication Union (ITU)  standardized, what it called \"International Morse Code\". When I say Morse Code for the remainder of this podcast, I am referring to this ITU International Morse Code.   \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nMorse code typically includes the following characters: \n

                                                              \n

                                                              \n
                                                              \n

                                                              \n
                                                                \n
                                                              • \n\nThe 26 letter basic Latin alphabet \n
                                                                • \n
                                                              • \n\nThe Indo-Arabic numerals 0 to 9 \n
                                                                • \n
                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nThere is also a single accented Latin letter (É), which is written as an E with an accent mark, and a handful of punctuation marks. \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nThese characters are encoded using a sequence of short and long signals. Each short signal is referred to as a \n\ndit\n\n. Each long signal is referred to as a \n\ndah\n\n. At a young age, I began to refer to them as dots and dashes, as this is how they are usually written. For example, the letter \"A\" consists of a single dit followed by a single dah. When written out this would look like a period followed by a hyphen (what some might call a minus sign)   .- \n\n \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nThis encoding method allows messages to be sent by \n\nturning on and off an electrical signal. This could result in a light flashing or a tone sounding to the pattern of the signal. The timing of a dit and dah, along with the spacing between them is carefully defined.  \n\n \n

                                                              \n\nMorsecode.world does a great job explaining the timing, and you can find their explanation at \n\nhttps://morsecode.world/international/timing/\n\n  \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nIt all starts with the dit, or more accurately, the amount of time the dit signal is turned on. We will call this length of time 1 unit. We will get to the actual length of time for a unit later in this episode. For now, it is just one unit.\n\n \n

                                                              \n

                                                              \n\n \n

                                                              \n

                                                              \n\nSo, if a dit is 1 unit long, a dah will be 3 units long, so there is an obvious and consistent difference between a dit and a dah. Also, empty space between elements of the same character is 1 unit long. The space between characters should be 3 units long.\n\n \n

                                                              \n\nRemember when we send these grouped together like a word, we need 3 units of spacing between each character. You can hear this now. This is Morse code for the letters \"HPR\" at 15 words per minute  .... .--. .-. \n

                                                              \n

                                                              \n

                                                              \n\n \n

                                                              \n\nThe speed of morse code is measured in \"words per minute\". But how do you calculate this when some characters are short (Like the letter \"E\" which is only a single dit long), and other characters are long (Like the letter \"J\" which starts with a single dit and is followed by 3 dahs)?\n\n \n

                                                              \n

We could not keep it that simple. Some guy named \n\nDonald R. \"Russ\" Farnsworth had to complicate things and increase the gaps between letters and words to make interpreting code much easier. There are even more maths for Farnsworth timing...\n\n \n

If you know or are interested in researching it, I look forward to listening to your show in the future.\n\n \n

(\n\nhttps://morsecode.world/international/timing/farnsworth.html\n\n ). But I don't want to get into all of it in detail here. Not when there is a shortcut we can use in our code. Simplified, we can take 1,200 and divide it by the WPM we desire, and it will give us a close enough approximation of the number of milliseconds long a dit should be.\n\n \n
