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.</p>\r\n<h3 id=\"alarm-frame-count\">Alarm Frame Count</h3>\r\n<p>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.</p>\r\n<p><a href=\"https://forums.zoneminder.com/viewtopic.php?f=36&t=26222\" class=\"uri\">https://forums.zoneminder.com/viewtopic.php?f=36&t=26222</a></p>\r\n<p>Windows software to get basic idea ( install face plugin )<br />\r\n<a href=\"https://www.ispyconnect.co

I thought that was two years ago, but wow it\'s even two and a half years ago, back in late 2015.</p>\r\n<p>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 \r\n<a href=\"https://f-droid.org/packages/com.github.axet.audiorecorder/\">Audio Recorder</a> and you\'re good to go!</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>It even has an automatic skip silence function, but that\'s pretty useless for the places I record in. :-D</p>\r\n<p>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.</p>',311,0,0,'CC-BY-SA','android, recording, hpr',0,0,1),

It uses Ruby.</p>\r\n<p>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 <a href=\"https://gitlab.com/\">gitlab.com</a> (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 <a href=\"https://jekyllrb.com/\">Jekyll</a> (use the static site generator of your choice) to copy files over for deploying, and finally GitLab Pages deploys the new site.</p>\r\n<p>I believe all of this took me less than two hours to set up, effective time, once I got around to it (and was in the same time zone as my dad\'s computer).

(2558,'2018-05-23','Battling with English - part 1',678,'Misunderstandings about English grammar, spelling, punctuation, etc.','<h1 id=\"battling-with-english---part-1\">Battling with English - part 1</h1>\r\n<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<p>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 <strong>correct</strong> in an absolute way.</p>\r\n<p>For example, when I was at school we were taught that "<em>nice</em>" should not be used in written material. At that time it was becoming common to see phrases like "<em>I had a nice time</em>" meaning <em>pleasant</em> (in a bland sort of way). In my "<em>Concise Oxford Dictionary</em>" from 1976 the 6th definition, "<em>agreeable</em>" is marked "<em>colloquialism</em>", whereas today this is a common usage.</p>\r\n<p>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.</p>\r\n<p>In this series I want to examine some of the problem areas and try to give you the means of remembering the <strong>right</strong> way.</p>\r\n<p><strong>Note</strong>: I\'m not an authority on this stuff, but I have tried to teach myself not to make these mistakes over the years. I just wanted to share what I have learnt<a href=\"#fn1\" class=\"footnoteRef\" id=\"fnref1\"><sup>1</sup></a> with some links to higher authorities.</p>\r\n<h2 id=\"long-notes\">Long notes</h2>\r\n<p>I have provided detailed notes as usual, and these can be <a href=\"https://hackerpublicradio.org/eps/hpr2558/full_shownotes.html\">viewed here</a>.</p>\r\n<h2 id=\"links\">Links</h2>\r\n<ul>\r\n<li>Then:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/then\">Definition of "then"</a></li>\r\n<li><a href=\"https://www.etymonline.com/word/then\">Online Etymology Dictionary</a></li>\r\n</ul></li>\r\n<li>Than:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/than\">Definition of "than"</a></li>\r\n<li><a href=\"https://www.etymonline.com/word/than\">Online Etymology Dictionary</a></li>\r\n</ul></li>\r\n<li>Then versus Than\r\n<ul>\r\n<li>Writing Explained: <a href=\"https://writingexplained.org/then-vs-than-difference\">Then vs. Than: What’s the Difference?</a></li>\r\n<li>Grammarist: <a href=\"https://grammarist.com/usage/than-then/\">Than vs. then</a></li>\r\n<li>Merriam-Webster: <a href=\"https://www.merriam-webster.com/words-at-play/when-to-use-then-and-than\">When To Use Then and Than</a></li>\r\n</ul></li>\r\n<li>There:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/there\">Definition of "there"</a></li>\r\n<li><a href=\"https://www.etymonline.com/word/there\">Online Etymology Dictionary</a></li>\r\n</ul></li>\r\n<li>Their:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/their\">Definition of "their"</a></li>\r\n<li><a href=\"https://www.etymonline.com/word/their\">Online Etymology Dictionary</a></li>\r\n</ul></li>\r\n<li>They\'re:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/they%27re\">Definition of "they\'re"</a></li>\r\n</ul></li>\r\n<li>Tenet:\r\n<ul>\r\n<li>Oxford Dictionaries: <a href=\"https://en.oxforddictionaries.com/definition/tenet\">Definition of "tenet"</a></li>\r\n<li><a href=\"https://www.etymonline.com/word/tenet\">Online Etymology Diction

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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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 t

I had thought of getting a <a href=\"https://www.prusaprinters.org/prusa-i3/\" title=\"Prusa i3 MK3\">Prusa i3 MK3</a> 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.

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.</p>\r\n<p>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:</p>\r\n<p><a href=\"https://www.cnet.com/products/hp-compaq-elite-8300-cmt-core-i7-3770-3-4-ghz-4-gb-1-tb-b2d12utaba/specs/\" class=\"uri\">https://www.cnet.com/products/hp-compaq-elite-8300-cmt-core-i7-3770-3-4-ghz-4-gb-1-tb-b2d12utaba/specs/</a></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n',338,57,0,'CC-BY-SA','Computers, Repair, safety',0,0,1),

(2595,'2018-07-13','New laptop bargain?',252,'This is a short show about another trip to the computer auction and one of my purchases','<p>Greetings HPR listeners this is Tony Hughes again coming from Blackpool in the UK. 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:</p>\r\n<p><a href=\"https://www.realnorth.co.uk/\" class=\"uri\">https://www.realnorth.co.uk/</a></p>\r\n<p>So at the sale in June they had some really good 3-4 year old laptops for sale so I decided to take a trip and see if I could liberate a few bargains, and one of the items I came away with was 3 Toshiba Z30a Ultra Books of the i5 4th generation. The basic specs are:</p>\r\n<ul>\r\n<li>i5-4300U CPU</li>\r\n<li>128GB mSATA solid state drive</li>\r\n<li>13.3 inch display</li>\r\n<li>8Gig DDR Ram</li>\r\n<li>3 x USB3 ports</li>\r\n<li>VGA and HDMI video out</li>\r\n<li>Full Ethernet Port</li>\r\n<li>Combined Audio in/out jack</li>\r\n<li>SD card reader</li>\r\n<li>Mobile Intel ® HD Graphics with up to 1792MB dynamically allocated</li>\r\n<li>shared graphics memory.</li>\r\n</ul>\r\n<p>There will be a link in the show notes to the full specifications</p>\r\n<p><a href=\"https://www.toshiba.co.uk/discontinued-products/portege-z30-a-1fd/\" class=\"uri\">https://www.toshiba.co.uk/discontinued-products/portege-z30-a-1fd/</a></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n',338,57,0,'CC-BY-SA','computer auction,laptop',0,0,1),

(2609,'2018-08-02','SparkleShare',1460,'Klaatu demonstrates SparkleShare','<p>\r\nClacke mentioned SparkleShare in <a href=\"https://hackerpublicradio.org/eps.php?id=2542\" target=\"_blank\">episode 2542</a>, and it occurred to me that not everyone knows what Sparkleshare is. So here's a show about it.\r\n</p>\r\n\r\n<p>\r\nTo setup SparkleShare, refer to <a href=\"https://sparkleshare.org\" target=\"_blank\">SparkleShare.org</a>. It\'s available for Linux, Windows, and Mac; great for cross-platform collaboration.\r\n</p>\r\n\r\n<p>\r\nThe Linux installer uses <a href=\"https://flatpak.org\" target=\"_blank\">FlatPak</a>, so you do need to install that.\r\n</p>\r\n\r\n<p>\r\nOnce installed, launch SparkleShare in the usual way. If you have no usual way, you can use this command:</p>\r\n\r\n<pre>\r\n$ flatpak run org.sparkleshare.SparkleShare\r\n</pre>\r\n\r\n<p>\r\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.\r\n</p>\r\n\r\n<p>\r\nThe next screen displays the <strong>Sync Remote Project</strong> screen. You use this screen any time you want to add another share to your sparkle.\r\n</p>\r\n\r\n<img src=\"https://slackermedia.info/host/setup1.png\" alt=\"image showing the Sync Remote Project window of SparkleShare\" />\r\n\r\n<p>\r\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.\r\n</p>\r\n\r\n<p><strong>Adding a project from Gitlab</strong></p>\r\n\r\n<p>\r\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.\r\n</p>\r\n\r\n<img src=\"https://slackermedia.info/host/clientid.png\" alt=\"image describing the menu selection as listed in the above text\" />\r\n\r\n<p>\r\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 <strong>Settings</strong> screen. When your SSH Key has been added, Gitlab displays a key fingerprint (actually just a string of numbers) as confirmation.\r\n</p>\r\n\r\n<p>\r\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 <code>gitlab.com/notklaatu/foo.git</code> then the path that SparkleShare needs is <code>notklaatu/foo.git</code>\r\n</p>\r\n\r\n<p>\r\nClick the <strong>Add</strong> button to add the project to your local SparkleShare folder.\r\n</p>\r\n\r\n\r\n<p><strong>Adding a project hosted on your own server</strong></p>\r\n\r\n<p>\r\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:\r\n</p>\r\n\r\n<ul>\r\n<li><p>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.</p></li>\r\n<li><p>Your SparkleShare auto-generated "Client ID" is located in <code>$HOME/.config/org.sparkleshare.SparkleShare/ssh</code></p></li>\r\n<li><p>Is your SparkleShare SSH key (the "Client ID" in SparkleShare lingo) in your authorized_hosts file?\r\n</p></li>\r\n<li><p>Does a Git repository exist on your remote server in the location you think it exists?</p></li>\r\n</ul>\r\n\r\n<p><strong>Using SparkleShare</strong></p>\r\n\r\n<p>\r\nUse SparkleShare exactly as you would DropBox or the <a href=\"https://nextcloud.com/\" target=\"_blank\">NextCloud Desktop Client</a>: drag-and-drop a file to add it, drag it to the Trash to delete it. All SparkleShare folders sync\'d with any given project syncs automatically through the magickalfulness of Gi

Introduction and tutorial.','<h1 id=\"a-gentle-introduction-to-quilt\">A gentle introduction to quilt</h1>\r\n<p>Or, patch management for software.</p>\r\n<h2 id=\"speaker-intro\">Speaker Intro</h2>\r\n<p>Hi, I\'m bjb. I\'m a programmer.</p>\r\n<h2 id=\"motivation-and-topic-intro\">Motivation and topic intro</h2>\r\n<p>I needed to learn how to use the software tool "quilt", so you get to listen to my podcast about an introduction to quilt.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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".</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>By default there are 3 lines of context before and after the changed lines.</p>\r\n<p>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 ove

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.

If I miss something you may find it in the user manual link above.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h3 id=\"the-speech-compressor\">The Speech Compressor</h3>\r\n<p>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.</p>\r\n<p>IC meter position indicates the power transistor collector current</p>\r\n<p>VC meter position indicates the power transistor collector voltage</p>\r\n<p>Noise Blanker 1 (NB1)<br />\r\nFor pulse type noise, such as generated by automatic ignition systems.</p>\r\n<p>Noise Blanker 2 (NB2)<br />\r\nFor long duration pulse noise, like the Russian woodpecker.</p>',201,43,1,'CC-BY-SA','Amateur, Radio, Ham',0,0,1),

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, <a href=\"https://oneeyeopen.podbean.com/\">One Eye Open</a>, which Dave started listening to a couple of weeks ago.

(2663,'2018-10-17','Short review on a 2.5 inch SSD/HDD caddy',202,'Tony reviews a Short review on a 2.5 inch SSD/HDD caddy from ebay','<p>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.</p>\r\n<p>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.</p>\r\n<p>So I purchased a caddy off that font of all things techie E-bay for £5.50, link here:<br />\r\n<a href=\"https://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\">https://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</a></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>I am very happy with this purchase and it has already become a regular part of my travelling tool kit/laptop bag.</p>\r\n',338,23,0,'CC-BY-SA','Computers, Tool Bag',0,0,1),

(2664,'2018-10-18','My git workflow',495,'In this episode I talk about the workflow I use to contribute to opensource project using git','<h2 id=\"my-git-workflow\">My git workflow</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Once the project is forked, I clone it on my machine :</p>\r\n<pre><code>$ git clone git://server/path/to/myproject.git</code></pre>\r\n<p>Git automatically names my remote project <code>origin</code>.</p>\r\n<p>Then I add a reference to the original project :</p>\r\n<pre><code>$ git remote add upstream https://server/path/to/originalproject.git</code></pre>\r\n<p>Now my local repository references my fork under the name <code>origin</code> and the original project under the name <code>upstream</code>.</p>\r\n<p>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 :</p>\r\n<pre><code>$ git checkout -b bugfix</code></pre>\r\n<p>I can then make changes, test my code, make sure everything is ok, stage and commit my changes :</p>\r\n<pre><code>$ git add .\r\n$ git commit -m "commit message"</code></pre>\r\n<p>Now I need to push this local branch to my repository on github :</p>\r\n<pre><code>$ git push -u origin bugfix</code></pre>\r\n<p>Since I forked the original project, github knows that <code>origin</code> and <code>upstream</code> 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 <code>upstream</code>’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 <code>upstream</code>’s changes, and merge them :</p>\r\n<pre><code>$ git checkout master\r\n$ git fetch upstream\r\n$ git merge upstream/master</code></pre>\r\n<p>Now my local master branch is ahead of <code>origin</code>’s master branch, so I push those changes to github :</p>\r\n<pre><code>$ git push</code></pre>\r\n<p>I don’t need the <code>bugfix</code> branches (the local one and the github one), so I can delete those :</p>\r\n<pre><code>$ git branch -d bugfix\r\n$ git push origin -d bugfix</code></pre>\r\n<p>And now, my local repository is even with both <code>origin</code> and <code>upstream</code>, and I can start again.</p>\r\n<p>To summarize, here’s the complete workflow :</p>\r\n<pre><code>$ git checkout -b myawesomefeature\r\n$ git add .\r\n$ git commit -m "Awesome commit message"\r\n$ git push -u origin myawesomefeature</code></pre>\r\n<p>Create a pull request, wait for the maintainer to merge it.</p>\r\n<pre><code>$ git checkout master\r\n$ git fetch upstream\r\n$ git merge upstream/master\r\n$ git push\r\n$ git branch -d myawesomefeature\r\n$ git push origin -d myawesomefeature</code></pre>\r\n',370,104,0,'CC-0','git,github,workflow',0,0,1),

(2672,'2018-10-30','Porteus',3477,'Installing Porteus and the cool things you can do with thumbdrive installation','<p><a href=\"https://porteus.org\" target=\"_blank\">Porteus</a> is a portable Live Linux distro, based on Slackware, intended for use on thumbdrives or optical media. It is, more or less, the new <a href=\"https://hackerpublicradio.org/eps.php?id=0055\" target=\"_blank\">Slax</a>, now that Slax has switched to Debian.</p>\r\n\r\n<h2>Install</h2>\r\n\r\n<p>The official means of installation is to burn Porteus to disc, and then (optionally) install Porteus onto a thumbdrive from within Porteus. 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.</p>\r\n<p>\r\nFrom either Porteus or Slackware (you can try other distros, but results <em>will</em> vary), you can do a manual install, and here are the correct commands (as of this writing, the docs on porteus.org are not accurate). Assuming you have discovered, using <code>lsblk</code>, that your target device (the thumbdrive) is <code>/dev/sdx</code>:\r\n</p>\r\n\r\n<pre><code>$ sudo bash\r\n# mkdir -p /mnt/loop /mnt/drive\r\n# mount --options loop /path/to/Porteus*iso /mnt/loop\r\n# mount /dev/sdx1 /mnt/drive\r\n# rsync -av /mnt/loop/ /mnt/drive/\r\n# cd /mnt/drive/boot\r\n# chmod +x Porteus-installer-for-Linux.com\r\n# ./Porteus*com\r\n</code></pre>\r\n\r\n<p>\r\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 <a href=\"https://virt-manager.org/\" target=\"_blank\">virt-manager</a> running on Fedora successfully for this.\r\n</p>\r\n\r\n<p>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.</p>\r\n\r\n<h2>Boot</h2>\r\n\r\n<p>\r\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:\r\n</p>\r\n\r\n<p> Insert your USB stick (or DVD) into the computer.</p>\r\n<p>Restart the computer.</p>\r\n<p>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.\r\n</p>\r\n<p>\r\nOn Macs, keep your finger pressed on the Alt or Option key after hearing the boot sound.\r\n</p>\r\n\r\n<h2>Boot modes</h2>\r\n\r\n<p>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.\r\n</p>\r\n<p>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.</p>\r\n\r\n<h2>Installing software</h2>\r\n\r\n<p>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.</p>\r\n\r\n<p>\r\nTo install software, you mu

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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Submitting this show mostly because I’m curious what the community thinks of the idea.</p>\r\n',151,0,1,'CC-0','spoken language learning',0,0,1),

In database two first ones are:</p>\r\n\r\n<pre><code>\r\nPlanet json\r\n name Text\r\n position Int\r\n starSystemId StarSystemId\r\n ownerId FactionId Maybe\r\n gravity Double\r\n SystemPosition starSystemId position\r\n deriving Show\r\n\r\nPlanetReport json\r\n planetId PlanetId\r\n ownerId FactionId Maybe\r\n starSystemId StarSystemId\r\n name Text Maybe\r\n position Int Maybe\r\n gravity Double Maybe\r\n factionId FactionId\r\n date Int\r\n deriving Show\r\n</code></pre>\r\n<p>Third one is defined as a datatype:</p>\r\n\r\n<pre><code>\r\ndata CollatedPlanetReport = CollatedPlanetReport\r\n { cprPlanetId :: Key Planet\r\n , cprSystemId :: Key StarSystem\r\n , cprOwnerId :: Maybe (Key Faction)\r\n , cprName :: Maybe Text\r\n , cprPosition :: Maybe Int\r\n , cprGravity :: Maybe Double\r\n , cprDate :: Int\r\n } deriving Show\r\n</code></pre>\r\n\r\n<p>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 <em>ReportTransform</em> type class:</p>\r\n\r\n<pre><code>\r\n-- | Class to transform a report stored in db to respective collated report\r\nclass ReportTransform a b where\r\n fromReport :: a -> b\r\n\r\ninstance ReportTransform PlanetReport CollatedPlanetReport where\r\n fromReport report =\r\n CollatedPlanetReport (planetReportPlanetId report)\r\n (planetReportStarSystemId report)\r\n (planetReportOwnerId report)\r\n (planetReportName report)\r\n (planetReportPosition report)\r\n (planetReportGravity report)\r\n (planetReportDate report)\r\n</code></pre>\r\n\r\n<p>To easily combine bunch of collated reports together, we define instances\r\n of <em>semigroup</em> and <em>monoid</em> for collated report data.\r\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 <a href=\"https://wiki.haskell.org/Monoid\">https://wiki.haskell.org/Monoid</a> which explains it in detail.</p>\r\n\r\n<pre><code>\r\ninstance Semigroup CollatedPlanetReport where\r\n (<>) a b = CollatedPlanetReport (cprPlanetId a)\r\n (cprSystemId a)\r\n (cprOwnerId a <|> cprOwnerId b)\r\n (cprName a <|> cprName b)\r\n (cprPosition a <|> cprPosition b)\r\n (cprGravity a <|> cprGravity b)\r\n (max (cprDate a) (cprDate b))\r\n\r\ninstance Monoid CollatedPlanetReport where\r\n mempty = CollatedPlanetReport (toSqlKey 0) (toSqlKey 0) Nothing Nothing Nothing Nothing 0\r\n</code></pre>\r\n\r\n<p>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:</p>\r\n\r\n<pre><code>\r\n-- | Class to indicate if two reports are about same entity\r\nclass Grouped a where\r\n sameGroup :: a -> a -> Bool\r\n\r\ninstance Grouped PlanetReport where\r\n sameGroup a b =\r\n planetReportPlanetId a == plane

(2713,'2018-12-26','Resources in 4x game',1252,'One way to implement data types for raw resources in Haskell','<p>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.</p>\r\n<p>RawResource is basic building block:</p>\r\n<pre><code>newtype RawResource a = RawResource { unRawResource :: Int }\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>It can be parametrised with anything, but I’m using three different types:</p>\r\n<pre><code>data Biological = Biological\r\ndata Mechanical = Mechanical\r\ndata Chemical = Chemical</code></pre>\r\n<p>Example of defining harvest being 100 units of biological raw resources:</p>\r\n<pre><code> harvest :: RawResource Biological\r\n harvest = RawResource 100</code></pre>\r\n<p>Raw resources are often manipulated (added and subtracted mostly). Defining Num instance allows us to use them as numbers:</p>\r\n<pre><code>instance Num (RawResource t) where\r\n (+) (RawResource a) (RawResource b) = RawResource $ a + b\r\n (-) (RawResource a) (RawResource b) = RawResource $ a - b\r\n (*) (RawResource a) (RawResource b) = RawResource $ a * b\r\n abs (RawResource a) = RawResource $ abs a\r\n signum (RawResource a) = RawResource $ signum a\r\n fromInteger a = RawResource $ fromInteger a</code></pre>\r\n<p>For example, adding harvest to stock pile:</p>\r\n<pre><code> stock :: RawResource Biological\r\n stock = RawResource 1000\r\n\r\n harvest :: RawResource Biological\r\n harvest = RawResource 100\r\n\r\n newStock = stock + harvest</code></pre>\r\n<p>Comparing size of two resource piles is common operation. Ord instance has methods we need for comparing:</p>\r\n<pre><code>instance Ord (RawResource t) where\r\n (<=) (RawResource a) (RawResource b) = a <= b</code></pre>\r\n<p>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.</p>\r\n<p>Another way to add bunch of resources of same type together is defining Monoid instance:</p>\r\n<pre><code>instance Semigroup (RawResource t) where\r\n (<>) a b = a + b\r\n\r\ninstance Monoid (RawResource t) where\r\n mempty = RawResource 0</code></pre>\r\n<p>For example, combining harvests of many fields can be achieved as:</p>\r\n<pre><code> harvests :: [RawResource Biological]\r\n harvests = [RawResource 20, RawResource 50, RawResource 25]\r\n\r\n total :: RawResource Biological\r\n total = mappend harvests</code></pre>\r\n<p>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.</p>\r\n<p>Raw resources are often grouped together for specific purpose. This again uses phantom types to keep track the intended usage:</p>\r\n<pre><code>data RawResources a = RawResources\r\n { ccdMechanicalCost :: RawResource Mechanical\r\n , ccdBiologicalCost :: RawResource Biological\r\n , ccdChemicalCost :: RawResource Chemical\r\n } deriving (Show, Read, Eq)\r\n\r\ndata ResourceCost = ResourceCost\r\ndata ConstructionSpeed = ConstructionSpeed\r\ndata ConstructionLeft = ConstructionLeft\r\ndata ConstructionDone = ConstructionDone\r\ndata ResourcesAvailable = ResourcesAvailable</code></pre>\r\n<p>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:</p>\r\n<pre><code>instance Semigroup (RawResources t) where\r\n (<>) a b = RawResources\r\n { ccdMechanicalCost = ccdMechanicalCost a <> ccdMechanicalCost b\r\n , ccdBiologicalCost = ccdBiologicalCost a <> ccdBiologicalCost b\r\n , ccdChemicalCost = ccdChemicalCost a <> ccdChemicalCost b\r\n }\r\n\r\ninstance Monoid (RawResources t) where\r\n mempty = RawResources\r\n { ccdMechanicalCost = mempty\r\n , ccdBiologicalCost = mempty\r\n

(2707,'2018-12-18','Steganalysis 101',864,'Steganalysis is the process of identifying the presence of, and decrypting, steganography.','<h3 id=\"introduction\">1. Introduction</h3>\r\n<p>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.</p>\r\n<h3 id=\"what-is-steganography\">2. What is steganography?</h3>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h3 id=\"examples-also-from-wikipedia-the-great-repository-of-all-knowledge\">3.

Also, those servers sometimes need a keyboard and a mouse, and with only one USB port, that’s not too practical.</p>\r\n<p>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.

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.</p>\r\n<p>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.</p>\r\n<p>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. <a href=\"https://goo.gl/images/7xv5A5\">DC-9 stick shaker, a big cell phone vibrator</a> 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)</p>\r\n<p>Author: Brian<br />\r\nCreated: 2018-12-01 Sat 07:34<br />\r\nEmacs 25.3.1 (Org mode 8.2.10)</p>\r\n',326,0,0,'CC-BY-SA','aircraft,flight,stall',0,0,1),

(2723,'2019-01-09','Using Elm in context of 4X game client',2671,'Tuula talks their decisions on structuring Elm application','<p>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.</p>\r\n<p>Couple goals I had in my mind when I started this:</p>\r\n<ul>\r\n<li>easy to work with</li>\r\n<li>type safe</li>\r\n<li>extensible</li>\r\n<li>user authorization\r\n<ul>\r\n<li>regular player</li>\r\n<li>administrator</li>\r\n</ul></li>\r\n</ul>\r\n<p>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.</p>\r\n<h2 id=\"api-endpoints\">API Endpoints</h2>\r\n<p>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.</p>\r\n<pre><code>type Endpoint\r\n = ApiStarDate\r\n | ApiResources\r\n | ApiStarSystem\r\n | ApiStar\r\n | ApiPlanet\r\n | ApiPopulation PlanetId\r\n | ApiBuilding PlanetId\r\n | ApiConstructionQueue PlanetId\r\n | ApiConstruction Construction\r\n | ApiBuildingConstruction\r\n | ApiAvailableBuildings</code></pre>\r\n<p>For example, sending a GET request to retrieve all construction projects on a planet is done as:</p>\r\n<pre><code>Http.send (ApiMsgCompleted << ConstructionsReceived) (get (ApiConstructionQueue planetId) (list constructionDecoder))</code></pre>\r\n<p>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.</p>\r\n<h2 id=\"update-function\">Update function</h2>\r\n<p>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).</p>\r\n<p>Same way as API end points are encoded in a type, pages are too:</p>\r\n<pre><code>type Route\r\n = HomeR\r\n | ProfileR\r\n | StarSystemsR\r\n | StarSystemR StarSystemId\r\n | PlanetR StarSystemId PlanetId\r\n | BasesR\r\n | FleetR\r\n | DesignerR\r\n | ConstructionR\r\n | MessagesR\r\n | AdminR\r\n | LogoutR\r\n | ResearchR</code></pre>\r\n<p>routeToString function is used to map Route into String, that can be placed in hyperlink. Below is an excerp:</p>\r\n<pre><code>routeToString : Route -> String\r\nrouteToString route =\r\n case route of\r\n HomeR ->\r\n "/home"\r\n\r\n StarSystemR (StarSystemId sId) ->\r\n "/starsystem/" ++ String.fromInt sId\r\n\r\n PlanetR (StarSystemId sId) (PlanetId pId) ->\r\n "/starsystem/" ++ String.fromInt sId ++ "/" ++ String.fromInt pId</code></pre>\r\n<p>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:</p>\r\n<pre><code>routes : Parser (Route -> a) a\r\nroutes =\r\n oneOf\r\n [ map HomeR top\r\n , map ProfileR (s "profile")\r\n , map ResearchR (s "research")\r\n , map StarSyste

(2717,'2019-01-01','Mobile Device Security',621,'Cell phone cyber security 101','<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h3 id=\"passive-surveillance\">1. Passive Surveillance</h3>\r\n<p>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.</p>\r\n<p>Defense here is a bit more complicated for the general user, but shouldn’t be too intrusive for most:</p>\r\n<ol type=\"1\">\r\n<li>Use a VPN on your mobile devices.</li>\r\n<li>Switch to a DNS provider that provides secure DNSSEC.</li>\r\n<li>Implement proper encryption on access points.</li>\r\n</ol>\r\n<h3 id=\"spyware\">2. Spyware</h3>\r\n<p>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.

(2727,'2019-01-15','Passwords',467,'How to do passwords better. ','<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<h2 id=\"passwords\">Passwords</h2>\r\n<p>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?</p>\r\n<p>For me personally I employ and advise a three faceted approach:</p>\r\n<ol type=\"1\">\r\n<li>Complex passwords</li>\r\n<li>Unique passwords</li>\r\n<li>Two-factor authentication (where available)</li>\r\n</ol>\r\n<p>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:</p>\r\n<h2 id=\"password-managers\">Password Managers</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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:</p>\r\n<p>Take a poem, song lyrics or phrase that is easy for you to remember. For this example I’ll use the phrase:</p>\r\n<pre><code>"The stars at night are big and bright. Deep in the heart of Texas."</code></pre>\r\n<p>Then I take the first letters from each word and that gives me:</p>\r\n<pre><code>TsanababdithoT.</code></pre>\r\n<p>Then I swap out the vowels for some numbers/special characters. And that gives me:</p>\r\n<pre><code>T5@n@b@bd1th0T</code></pre>\r\n<p>I checked that password on Dashlane’s Password Strength Checker, and got the following results:</p>\r\n<pre><code>It would take a computer about

After a lot of troubleshooting, I tracked it down to embedded images in the card. The PHOTO;VALUE field to be precise.</p>\r\n\r\n<p>Some images worked and some didn\'t, and looking at the properties some that worked were larger than others that didn\'t. In the end I tracked down a post on <a href=\"https://stackoverflow.com/questions/17834815/how-to-find-the-max-image-size-supported-for-contacts-images\">stackoverflow</a> that hinted that the aspect ratio was important. And sure enough it was.</p>\r\n\r\n<blockquote class=\"wp-block-quote\">\r\n<p>starting with jelly bean (4.1), android now supports contact images that are 720x720.<br />before, starting with ICS (4.0), android has supported contact images that are 256x256.<br />and before that, contact photos had just a size of a thumbnail - 96x96.</p>\r\n<cite><a href=\"https://stackoverflow.com/users/878126/android-developer\">Stack exchange</a> </cite>\r\n</blockquote>\r\n\r\n\r\n<p>I tried a 720x720 on a few phones but decided to settle on 256x256 for now. </p>\r\n\r\n\r\n<p>To do image manipulation, I tend to use the <a href=\"https://www.graphicsmagick.org/\">GraphicsMagick</a> tools instead of the more popular <a href=\"https://www.imagemagick.org/script/index.php\">ImageMagick</a> suite. You should be able to achieve the same result in either.</p>\r\n\r\n\r\n<p>My requirements were:</p>\r\n<ul>\r\n<li>The images should be scaled so that the maximum height/width shrinks to 256, maintaining the aspect ratio.</li>\r\n<li>The images should always be 256x256 in size.</li>\r\n<li>Scaled images should be padded and centered on a white background.</li>\r\n<li>All color profile information should be removed.</li>\r\n</ul>\r\n\r\n\r\n<p>To use an example I took the following image and saved it as Linus_Torvalds.jpg</p>\r\n\r\n\r\n<p>By <a title=\"User:Krd\" href=\"//commons.wikimedia.org/wiki/User:Krd\">Krd</a> (photo)<a class=\"new\" title=\"User:Von Sprat (page does not exist)\" href=\"//commons.wikimedia.org/w/index.php?title=User:Von_Sprat&action=edit&redlink=1\">Von Sprat</a> (crop/extraction) - <a title=\"File:LinuxCon Europe Linus Torvalds 03.jpg\" href=\"//commons.wikimedia.org/wiki/File:LinuxCon_Europe_Linus_Torvalds_03.jpg\">File:LinuxCon Europe Linus Torvalds 03.jpg</a>, <a title=\"Creative Commons Attribution-Share Alike 4.0\" href=\"https://creativecommons.org/licenses/by-sa/4.0\">CC BY-SA 4.0</a>, <a href=\"https://commons.wikimedia.org/w/index.php?curid=54706023\">Link</a></p>\r\n\r\n\r\n<p>Step one is to use the <a href=\"https://href="https://www.graphicsmagick.org/GraphicsMagick.html#details-size\">-size</a> 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.</p>\r\n\r\n<pre><code>$ gm convert -size 256x256 \"Linus_Torvalds.jpg\" Linus_Torvalds_1.jpg<br />$ gm identify Linus_Torvalds_1.jpg\r\nLinus_Torvalds_1.jpg JPEG 366x509+0+0 DirectClass 8-bit 56.1Ki 0.000u 0m:0.000002</code></pre>\r\n\r\n\r\n<p><img style=\"border-style: solid;\" src=\"https://hackerpublicradio.org/eps/hpr2730/Linus_Torvalds_1.jpg\" /></p>\r\n\r\n\r\n<p>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 <a href=\"https://www.graphicsmagick.org/GraphicsMagick.html#details-resize\">-resize</a> option.</p>\r\n\r\n<pre><code>\r\n$ gm convert -size 256x256 \"Linus_Torvalds.jpg\" -resize 256x256 Linus_Torvalds_2.jpg\r\n$ gm identify Linus_Torvalds_2.jpg\r\nLinus_Torvalds_2.jpg JPEG 184x256+0+0 DirectClass 8-bit 47.7Ki 0.000u 0m:0.000001s</code><code>\r\n</code></pre>\r\n\r\n<p><img style=\"border-style: solid;\" src=\"https://hackerpublicradio.org/eps/hpr2730/Linus_Torvalds_2.jpg\" /></p>\r\n\r\n<p>So this has done a good job at sca

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 <em>mirepoix</em> (/mɪərˈpwɑː/ meer-PWAH); but the idea is the same to give a base flavour to soups, sauces, risotto and stew type dishes.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p><a href=\"https://en.wikipedia.org/wiki/Sofrito\" class=\"uri\">https://en.wikipedia.org/wiki/Sofrito</a></p>\r\n',338,93,0,'CC-BY-SA','Food, cookery, how to, food preparation',0,0,1),

Either that or I find it’s got some better ideas than I’ve been using which I have to find out about.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p><small><b>Apology:</b> I’m still suffering from the aftermath of some flu-like illness so have had to edit coughing fits out of the audio at various points. If you detect any remnants then I’m sorry!</small></p>\r\n<h2 id=\"long-notes\">Long notes</h2>\r\n<p>I have provided detailed notes as usual for this episode, and these can be <a href=\"https://hackerpublicradio.org/eps/hpr2736/full_shownotes.html\">viewed here</a>.</p>\r\n<h2 id=\"links\">Links</h2>\r\n<ul>\r\n<li><a href=\"https://hackerpublicradio.org/eps.php?id=2720\">HPR episode 2720 “<em>hpr2720 :: Download youtube channels using the rss feeds</em>”</a></li>\r\n<li><a href=\"https://hackerpublicradio.org/eps/hpr2720/youtube-rss.bash\"><code>youtube-rss.bash</code></a></li>\r\n<li><a href=\"https://en.wikipedia.org/wiki/Cat_(Unix)\">Wikipedia article on <code>cat</code></a>\r\n<ul>\r\n<li><a href=\"https://en.wikipedia.org/wiki/Cat_(Unix)#Useless_use_of_cat\">Useless use of <code>cat</code></a></li>\r\n</ul></li>\r\n</ul>',225,42,1,'CC-BY-SA','Bash,ShellCheck',0,0,1),

(2738,'2019-01-30','My Applications',229,'just a short show on the applications I use on my Linux Mint Box','<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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</p>\r\n<p>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.</p>\r\n<p>Well that’s it for this one. This is Tony Hughes signing off for now.</p>\r\n',338,0,0,'CC-BY-SA','productivity software',0,0,1),

They’re dangerous and might eat harvest or people.</p>\r\n<p>Special events build on top of the new system I explained in <a href=\"https://hackerpublicradio.org/eps.php?id=2733\">episode 2733</a>. They are read from same API as regular news and need same <code>ToJSON</code>, <code>FromJSON</code>, <code>ToDto</code> and <code>FromDto</code> instances as regular news (for translating them data transfer objects and then into JSON for sending to client).</p>\r\n<h2 id=\"loading\">Loading</h2>\r\n<p>Starting from the API interface, the first real difference is when JSON stored into database is turned into <code>NewsArticle</code>. 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.</p>\r\n<pre><code>addOptions (key, article) = case article of\r\n Special news ->\r\n (key, Special $ availableOptions news)\r\n _ ->\r\n (key, article)\r\n\r\navailableOptions :: SpecialNews -> SpecialNews\r\navailableOptions x =\r\n case x of\r\n KragiiWorms event _ choice ->\r\n KragiiWorms event (eventOptions event) choice</code></pre>\r\n<p><code>eventOptions</code> is one of the events defined in <code>SpecialEvent</code> type class that specifies two functions every special event has to have. <code>eventOptions</code> lists what options the event has currently available and <code>resolveEvent</code> resolves the event according to choice user might have made (hence <code>Maybe</code> in it).</p>\r\n<p>Type class is parametrized with three types (imaginatively named to <code>a</code>, <code>b</code> and <code>c</code>). 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 <code>KragiiWormsEvent</code>, <code>KragiiWormsChoice</code> and <code>KragiiResults</code>.</p>\r\n<pre><code>data KragiiWormsEvent = KragiiWormsEvent\r\n { kragiiWormsPlanetId :: Key Planet\r\n , kragiiWormsPlanetName :: Text\r\n , kragiiWormsSystemId :: Key StarSystem\r\n , kragiiWormsSystemName :: Text\r\n , kragiiWormsDate :: Int\r\n }\r\n\r\ndata KragiiWormsChoice =\r\n EvadeWorms\r\n | AttackWorms\r\n | TameWorms\r\n\r\ndata KragiiResults =\r\n WormsStillPresent\r\n | WormsRemoved\r\n | WormsTamed\r\n | CropsDestroyed (RawResource Biological)\r\n | FarmersInjured</code></pre>\r\n<p>Definition of the <code>SpecialEvent</code> type class is shown below. Type signature of <code>resolveEvent</code> is gnarly because it’s reading and writing database.</p>\r\n<pre><code>class SpecialEvent a b c | a -> b, a -> c where\r\n eventOptions :: a -> [UserOption b]\r\n resolveEvent :: ( PersistQueryRead backend, PersistQueryWrite backend\r\n , MonadIO m, BaseBackend backend ~ SqlBackend ) =>\r\n (Key News, a) -> Maybe b -> ReaderT backend m (Maybe EventRemoval, [c])</code></pre>\r\n<p>One more piece we need is <code>UserOption</code>.

(2758,'2019-02-27','Haskell - Data types and database actions',2566,'Brief summary of how to declare your own datatypes in Haskell and how to store data in database','<h2 id=\"intro\">Intro</h2>\r\n<p>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).</p>\r\n<h2 id=\"data-types\">Data types</h2>\r\n<p>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 <code>data</code> followed with type name, equals sign and one or more value constructors. Type name and value constructors have to start with uppercase letter.</p>\r\n<p>Simplest type is following:</p>\r\n<pre><code>data Simple = One</code></pre>\r\n<p>This declares a type called <code>Simple</code> that has single possible value: <code>One</code>.</p>\r\n<p>More interesting type is shown below. <code>Colour</code> has three possible values: <code>Red</code>, <code>Green</code> and <code>Blue</code>.</p>\r\n<pre><code>data Colour =\r\n Red\r\n | Green\r\n | Blue</code></pre>\r\n<p>It’s possible to have parameters in value constructor. Following is <code>Payment</code> type that could be used to indicate how payment was done. In case of <code>Cash</code> amount is stored. In case of <code>IOU</code> free text is recorded.</p>\r\n<pre><code>data Payment =\r\n Cash Double\r\n | IOU Text</code></pre>\r\n<p>Fictional usage of the <code>Payment</code> is shown below. Function <code>paymentExplanation</code> takes a <code>Payment</code> as parameter and returns <code>Text</code> 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 <code>IOU</code> value.</p>\r\n<p><code>paymentExplanation :: Payment -> Text</code> part is type declaration. It states that <code>paymentExplanation</code> takes argument of type <code>Payment</code> and returns result as <code>Text</code>.</p>\r\n<pre><code>paymentExplanation :: Payment -> Text\r\npaymentExplanation payment =\r\n case payment of\r\n Cash amount ->\r\n "Cash payment of " <> (show amount) <> " euros"\r\n IOU explanation ->\r\n explanation</code></pre>\r\n<p>Parameters don’t have to be hard coded in the type definition. Parametrized types allows creating more general code. <code>Maybe</code> is very useful data type that is often used for data that might or might not be present.

(2754,'2019-02-21','Craigslist Scam Catch',460,'Helped a client avoid being scammed on Craigslist and wanted to share some tips to HPR.','<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>She then showed me the email thread with the shipping company.</p>\r\n<p>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 <code>reallylongcompanyname@outlook.com</code></p>\r\n<p>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 ad

(2757,'2019-02-26','How to DM',2694,'Klaatu explains how to DM an RPG, and Lostnbronx demonstrates, step by step, how to build a dungeon','<h2>Klaatu</h2>\r\n<p>\r\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.\r\nPeople have told me that one of the biggest blockers to getting started is knowing what to do as GM.</p><p>\r\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.\r\nSo in this episode, Lostnbronx and I are going to provide you with some clear and direct instructions on what exactly a GM does.\r\n</p><p>\r\nThe short version is this:</p>\r\n<ol><li><p>\r\nTell the players where they are and what they see around them.\r\n</p></li><li><p>\r\nListen to the players when they tell you what they want to do.\r\n</p></li><li><p>\r\nTell the players the outcome, based on your privileged knowledge of the game world or on a roll of the dice, of their actions.\r\n</p></li></ol>\r\n<p>\r\nYou loop over that sequence, and you\'re game mastering!\r\n</p><p>\r\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.\r\n</p><p>\r\nTo that end, Lostnbronx and I have started a <a href=\"https://mixedsignals.ml\" target=\"_blank\">website dedicated to gaming</a>! 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.\r\n</p>\r\n\r\n<h2>Lostnbronx</h2>\r\n<p>\r\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.\r\n</p><p>\r\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.\r\n</p><p>\r\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.\r\n</p><p>\r\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.\r\n</p><p>\r\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 othe

(2768,'2019-03-13','Writing Web Game in Haskell - Planetary statuses',1122,'Tuula describes system for recording planetary statuses in their game','<h2 id=\"intro\">Intro</h2>\r\n<p>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.</p>\r\n<h2 id=\"data-types-and-database\">Data types and Database</h2>\r\n<p>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.</p>\r\n<pre><code>data PlanetaryStatus =\r\n GoodHarvest\r\n | PoorHarvest\r\n | GoodMechanicals\r\n | PoorMechanicals\r\n | GoodChemicals\r\n | PoorChemicals\r\n | KragiiAttack\r\n\r\nderivePersistField "PlanetaryStatus"</code></pre>\r\n<p>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 <code>PlanetaryStatus</code> is much more informative than <code>String</code> or <code>Text</code>.</p>\r\n<p>For database, we use following definition shown below in models file. It creates database table <code>planet_status</code> and respective Haskell data type <code>PlanetStatus</code>. 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.</p>\r\n<pre><code>PlanetStatus json\r\n planetId PlanetId\r\n status PlanetaryStatus\r\n expiration Int Maybe\r\n deriving Show Read Eq</code></pre>\r\n<p><code>expiration</code> column doesn’t have <code>NOT NULL</code> constraint like all other columns in the table. This is reflected in <code>PlanetStatus</code> record where data type of <code>planetStatusExpiration</code> is <code>Maybe Int</code> instead of <code>Int</code>. So some statuses will have expiration time, while others might not. I originally chose to represent time as <code>Int</code> instead of own data type, but I have been recently wondering if that was really a good decision.</p>\r\n<h2 id=\"kragii-attack-redux\">Kragii attack, redux</h2>\r\n<p>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 <code>[Entity Planet]</code> data that contains all planets that match the criteria.</p>\r\n<pre><code>-- | Load planets that are kragii attack candidates\r\nkragiiTargetPlanets :: (MonadIO m, BackendCompatible SqlBackend backend\r\n , PersistQueryRead backend, PersistUniqueRead backend) =>\r\n Int -> Int -> Key Faction -> ReaderT backend m [Entity Planet]\r\nkragiiTargetPlanets pop farms fId = do\r\n planets <- E.select $\r\n E.from $ (planet `E.LeftOuterJoin` population `E.LeftOuterJoin` building `E.LeftOuterJoin` status) -> do\r\n E.on (status E.?.

(2778,'2019-03-27','Functor and applicative in Haskell',1841,'Brief introduction on functor and applicative patterns in Haskell and where they can be used','<p>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.</p>\r\n<h2 id=\"functor\">Functor</h2>\r\n<p>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.</p>\r\n<p>Functor type class is defined below. There’s one function <code>fmap</code> that takes two parameters: a function from <code>a</code> to <code>b</code> and structure <code>f a</code>. Result will be structure <code>f b</code>.</p>\r\n<pre><code>class Functor f where\r\n fmap :: (a -> b) -> f a -> f b</code></pre>\r\n<p>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).</p>\r\n<pre><code>-- | this really raises x to 2nd power and doesn't double it\r\ndouble x = x * x</code></pre>\r\n<p>Given a list of <code>Int</code> we can raise them to power of two by using <code>fmap</code>:</p>\r\n<pre><code>> fmap double [1, 2, 3, 4, 5]\r\n[1, 4, 9, 16, 25]</code></pre>\r\n<p>Since function being applied to structure is type of <code>(a -> b)</code>, we can change type of the value inside of the structure. Below is example of turning list of <code>Int</code> to list of <code>Text</code>.</p>\r\n<pre><code>> fmap show [1, 2, 3, 4, 5]\r\n["1", "2", "3", "4", "5"]</code></pre>\r\n<p>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, <code>fmap</code>, that takes function of type <code>(a -> b)</code> and structure <code>f a</code> and turns it into structure of <code>f b</code>. Details how this is actually done depend on the specific functor.</p>\r\n<p>Other common functor is <code>Maybe</code> that is often used in cases where data might or might not be present. <code>Maybe a</code> has two possible values <code>Just a</code> indicating that value <code>a</code> is present and <code>Nothing</code> indicating that there is no value present. When <code>fmap</code> is used in this context, <code>Just a</code> will turn to <code>Just b</code> and <code>Nothing</code> will stay as <code>Nothing</code>.</p>\r\n<pre><code>> fmap (x -> x * x) $ Just 2\r\nJust 4\r\n> fmap (x -> x * x) Nothing\r\nNothing</code></pre>\r\n<p><code>Either a b</code> is sometimes used for value that can be correct or an error. It has two value constructors <code>Right b</code> indicates that value is correct, <code>Left a</code> indicates an error case. <code>a</code> and <code>b</code> don’t have to be of same type (and usually aren’t). For example, if we have <code>Either Text Int</code>, then we have value where error case is <code>Text</code> and correct value is <code>Int</code>.</p>\r\n<pre><code>> fmap double $ Right 5\r\nRight 25\r\n> fmap double $ Left "distance calculation failed because of flux-capacitor malfunction"\r\nLeft "distance calculation failed because of flux-capacitor malfunction"</code></pre>\r\n<p>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 <code>fmap</code> functions together like in the example below. Pay attention to in which order nested functors are defined as <code>Maybe [Int]</code> and <code>[Maybe Int]</code> are different things. Former is for case where list of <code>Int</code> 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.</p>\r\n<pre><code>> (fmap . fmap) do

Well I did but it took another 5 years before I finally recorded my first show in my own right.</p>\r\n<p>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.</p>\r\n<ol type=\"1\">\r\n<li><p>hpr2051 :: My Linux Journey<br />\r\nReleased on 2016-06-13<br />\r\nin this episode I talked about my journey in computing and starting to use Linux</p></li>\r\n<li><p>hpr2056 :: Interview with a young hacker<br />\r\nReleased on 2016-06-20<br />\r\nThis was my first of several interviews with <span class=\"citation\" data-cites=\"All_about_Code\">@All_about_Code</span> at my local Raspberry Jam</p></li>\r\n<li><p>hpr2065 :: Whats in My Bag<br />\r\nReleased on 2016-07-01<br />\r\nLooking at this show so tells me I have to redo this show as my bag is very different these days</p></li>\r\n<li><p>hpr2076 :: What Magazines I read Part 1<br />\r\nReleased on 2016-07-18<br />\r\njust what the title said, I talked about the magazines I was reading at that point in time.</p></li>\r\n<li><p>hpr2087 :: Magazines I read Part 2<br />\r\nReleased on 2016-08-02<br />\r\nThis was a follow up of the last show</p></li>\r\n<li><p>hpr2097 :: New Toys<br />\r\nReleased on 2016-08-16<br />\r\nI talked about my hardware journey over the last 30 odd years and talked about the i7 system I had just bought 2nd hand</p></li>\r\n<li><p>hpr2101 :: What’s on my podcatcher<br />\r\nReleased on 2016-08-22<br />\r\nA show about the podcasts I listen to.</p></li>\r\n<li><p>hpr2144 :: An Interview with All About Code at Manchester BarCamp<br />\r\nReleased on 2016-10-20<br />\r\na follow up interview with Josh</p></li>\r\n<li><p>hpr2151 :: BarCamp Manchester part 2<br />\r\nReleased on 2016-10-31<br />\r\nAn interview with Claire, the organiser of BarCamp Manchester.</p></li>\r\n<li><p>hpr2157 :: BarCamp Manchester part 3<br />\r\nReleased on 2016-11-08<br />\r\nThis was an interview with Alan O’Donohoe who had started the Raspberry Jam movement</p></li>\r\n<li><p>hpr2257 :: Watt OS<br />\r\nReleased on 2017-03-28<br />\r\nAcer Aspire One Netbook – Review</p></li>\r\n<li><p>hpr2265 :: WattOS on Lenovo X61s<br />\r\nReleased on 2017<br />\r\nLenovo X61s – Review</p></li>\r\n<li><p>hpr2271 :: Raspberry Pi Zero W<br />\r\nReleased on 2017-04-17<br />\r\nReview Episode on the then New Pi Zero W</p></li>\r\n<li><p>hpr2280 :: Lenovo X61s Part 2<br />\r\nReleased on 2017-04-28<br />\r\nFollow up review after a SSD upgrade and using Linux Lite</p></li>\r\n<li><p>hpr2286 :: Surviving a Stroke<br />\r\nReleased on 2017-05-08<br />\r\nA very personal episode about my surviving a Stroke in February 2017</p></li>\r\n<li><p>hpr2295 :: MX Linux<br />\r\nReleased on 2017-

(2788,'2019-04-10','Looping in Haskell',2848,'Tuula describes some loop-like constructs in Haskell','<p>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.</p>\r\n<h2 id=\"recursion\">Recursion</h2>\r\n<p>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.</p>\r\n<p>Simple recursive definition:</p>\r\n<pre><code>fibs :: Integer -> Integer\r\nfibs 0 = 0\r\nfibs 1 = 1\r\nfibs n = fibs (n-1) + fibs (n-2)</code></pre>\r\n<p>When called with <code>0</code> result is <code>0</code>. When called with <code>1</code> result is <code>1</code>. For all other cases, <code>fibs</code> is called with values <code>n-1</code> and <code>n-1</code> and the results are summed together. This works fine when <code>n</code> is small, but calculation gets slow really quickly with bigger values.</p>\r\n<p>Another way is to define list of all Fibonacci numbers recursively:</p>\r\n<pre><code>allFibs :: [Integer]\r\nallFibs = 0 : 1 : zipWith (+) allFibs (tail allFibs)</code></pre>\r\n<p>Here a list is constructed. First element is <code>0</code>, second element is <code>1</code> 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.</p>\r\n<p>Common pattern of processing elements in a list, producing a new list:</p>\r\n<pre><code>addOne :: [Integer] -> [Integer]\r\naddOne [] = []\r\naddOne (x:xs) = x + 1 : addOne xs</code></pre>\r\n<p>Two cases, when called with an empty list <code>[]</code>, result is empty list. For all other cases, list is taken apart <code>(x:xs)</code>, <code>x</code> contains first element of the list and <code>xs</code> is rest of the list. Body of the function creates a new list where head is <code>x + 1</code> and tail is <code>addOne xs</code>. This processes whole list of <code>Integer</code> by adding one to each value. It also reverses the list.</p>\r\n<p>Second common pattern is processing a list and reducing it to a single value:</p>\r\n<pre><code>sumAll :: Integer -> [Integer] -> Integer\r\nsumAll n [] = n\r\nsumAll n (x:xs) = sumAll (n + x) xs</code></pre>\r\n<p>If given list is empty (the terminal case), result is <code>n</code>. Second case again takes list apart <code>(x:xs)</code>, adds <code>x</code> and <code>n</code> together and recursive call <code>sumAll</code> with tail of the list.</p>\r\n<p>This common pattern is discarding some elements of a list:</p>\r\n<pre><code>evenOnly :: [Integer] -> [Integer]\r\nevenOnly [] = []\r\nevenOnly (x:xs) = \r\n if even x\r\n then x : evenOnly xs\r\n else evenOnly xs</code></pre>\r\n<p>Again, result of empty list is just empty list. In all other cases we first check if <code>x</code> is even. If so, new list is constructed where head is <code>x</code> and tail is <code>evenOnly xs</code>. If <code>x</code> isn’t even, it’s discarded and <code>evenOnly</code> is called recursively with tail of the list.</p>\r\n<h2 id=\"more-tools\">More tools</h2>\r\n<p>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 <code>evenOnly</code> actually works as I thought it would). For that reason, there are tools that abstract these common patterns and given them names.</p>\r\n<p>First is <code>map</code>. It applies given function to each element of a list, thus producing a new list:</p>\r\n<pre><code>> map (+1) [1..10]\r\n[2, 3, 4, 5, 6, 7, 8, 9, 10, 11]\r\n> map odd [1..10]\r\n[True, False, True, False, True, False, True, False, True, False]</code></pre>\r\n<p>Second is <code>fold</code>.

These include handling special events as explained in <a href=\"https://hackerpublicradio.org/eps.php?id=2748\">episode 2748</a> and doing observations and report writing in manner described <a href=\"https://hackerpublicradio.org/eps.php?id=2703\">episode 2703</a>.</p>\n<pre><code>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</code></pre>\n<h2 id=\"more-mapping\">More mapping</h2>\n<p>Remember <code>map</code> and <code>fmap</code> that are used to run a function to each element in a list or general structure? <code>mapM</code> works in a similar way, but is used in monadic context. In <code>processTurn</code> function, we’re dealing with input and output and have IO monad present to allow us to do that (<code>MonadIO m</code> part of the type signature).</p>\n<p>If you step back a bit and squint a bit, then <code>map :: (a -> b) -> [a] -> [b]</code> and <code>fmap :: (a -> b) -> f a -> f b</code> and <code>mapM :: Monad m => (a -> m b) -> t a -> m (t b)</code> 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.</p>\n<p>The difference is that <code>map</code> works only for lists, <code>fmap</code> works for functors (that were covered in <a href=\"https://hackerpublicradio.org/eps.php?id=2778\">episode 2778</a>) and <code>mapM</code> works for structures in monadic context.</p>\n<p>Best way to contact me nowadays is either by email or through fediverse where I’m Tuula@mastodon.social.</p>\n',364,107,0,'CC-BY-SA','haskell, persistent',0,0,1),

(2808,'2019-05-08','Haskell function types',1469,'Tuula gives overview of function types in Haskell','<p>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.</p>\r\n<h2 id=\"concrete-types\">concrete types</h2>\r\n<p>Simplest case is where types are spelled out definitely. Function <code>add</code> below takes two <code>Integer</code> parameters and produces <code>Integer</code> value. Note that types are written in upper case.</p>\r\n<p><code>add :: Integer -> Integer -> Integer</code></p>\r\n<p>It’s possible to not use concrete types. In following example <code>a</code> (note the lower case) can be anything. So function takes two values of <code>a</code>, a <code>Boolea</code> and produces <code>a</code>. This is useful technique for writing very general functions.</p>\r\n<p><code>choose :: a -> a -> Boolean -> a</code></p>\r\n<h2 id=\"ad-hoc-polymorphism\">ad hoc polymorphism</h2>\r\n<p>In previous example, we wouldn’t be able to do much at all with <code>a</code> 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.</p>\r\n<p><code>add :: (Num a) => a -> a -> a</code></p>\r\n<p>This version of <code>add</code> again takes two parameters, both being type <code>a</code> and produces value <code>a</code>. But <code>(Num a) =></code> part in the signature constraints <code>a</code> to be instance of <code>Num</code>. This type class (I’ll talk about these some other time) defines that each instance of it will have set of functions: <code>+</code>, <code>-</code>, <code>*</code>, <code>negate</code>, <code>abs</code>, <code>signum</code> and <code>fromInteger</code>. So now our <code>add</code> function can use those functions, regardless of what specific type <code>a</code> is.</p>\r\n<h2 id=\"parametrized-functions\">parametrized functions</h2>\r\n<p>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: <code>first :: [a] -> Maybe a</code></p>\r\n<p><code>first</code> takes single parameter, list of <code>a</code> and returns <code>Maybe a</code>. <code>Maybe</code> is a type that is used to signify a value that might or might not be present and has following definition:</p>\r\n<pre><code>data Maybe a =\r\n Nothing\r\n | Just a</code></pre>\r\n<p>So our function would return <code>Nothing</code> when given an empty list and <code>Just a</code> when given a list of at least one element.</p>\r\n<h2 id=\"using-functions\">using functions</h2>\r\n<p>Function application in Haskell doesn’t require parentheses around arguments. Calling our <code>add</code> function is just <code>add 1 2</code>. If one of the values is result of another function call, we need to tell which parameters belong to which function. Using <code>$</code> is one option: <code>add 1 $ add 2 3</code>, another option is to use parentheses: <code>add 1 (add 2 3)</code>.</p>\r\n<p>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 <code>addLots 5</code> will produce same value as <code>add 1000 5</code>:</p>\r\n<pre><code>addLots = add 1000\r\naddLots 5</code></pre>\r\n<p>Another contrived example of partial application:</p>\r\n<pre><code>findPodcasts :: [Podcast] -> Text -> [Podcast]\r\nsearch = findPodcasts loadedPodcasts\r\nmyPodcasts = search "Tuula"</code></pre>\r\n<h2 id=\"functions-as-types\">functions as types</h2>\r\n<p>Functions h

(2809,'2019-05-09','The Blue Oak Model License and Its One Big Gotcha',1268,'Introducing and examining a new and elegant permissive software license.','<p>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.</p>\r\n<p>I’m no legal expert, so take all of this as sort of a rough introduction to the license.</p>\r\n<p>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.</p>\r\n<p>However: just note that it has a feature, some would say bug, that <em>might</em> be a big deciding factor in whether you feel comfortable with it (listen for details)</p>\r\n<p>Nevertheless, I believe this license, or at least its style of language, will soon become extremely common.</p>\r\n<p>Further links:</p>\r\n<ul>\r\n<li><a href=\"https://blueoakcouncil.org/license/1.0.0\">The Blue Oak Model License 1.0.0</a> — the license itself. You may also wish to read <a href=\"https://blueoakcouncil.org/2019/03/06/model.html\">the group’s statement</a> about their methodology and how the license came to be.</li>\r\n<li><a href=\"https://writing.kemitchell.com/2019/03/09/Deprecation-Notice.html\"><em>Deprecation Notice: MIT and BSD</em></a> — the blog post I mention in the recording, by Blue Oak council member, developer and IP lawyer Kyle Mitchell. He explains some problems he sees with the MIT and BSD licenses and how the BOML addresses them.</li>\r\n<li><a href=\"https://news.ycombinator.com/item?id=19347797\">Discussion on Hacker News</a> — This was a pretty good discussion. Kyle Mitchell also chimed in here to respond to some criticisms and tire-kicking of this license (you can recognize him by his handle <code>kemitchell</code>).</li>\r\n</ul>\r\n<p>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 <em>license terms</em>, not <em>authorship</em> or <em>credit</em>. So for them an attribution requirement is a requirement to include the <em>license terms</em> with any distributed copies, not a requirement to give authorship credit to people.</p>\r\n<p>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!</p>\r\n<ul>\r\n<li><a href=\"https://thelocalyarn.com/cgi-bin/yarncode/doc/licensing/LICENSE.md\">The Local Yarn License 1.0.0</a> — This is the license as it currently sits in an experimental branch in my project’s Fossil repository</li>\r\n<li><a href=\"https://thelocalyarn.com/cgi-bin/yarncode/technote/8dfa234a1779782be090b36a6b1bcccfabd95b20\">Notes about my customizations</a> — Another tech note from the Fossil repo.</li>\r\n</ul>\r\n<p>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.</p>\r\n',376,0,0,'CC-BY-SA','legal, licensing',0,0,1),

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.</p>\r\n<p>As a Swede, I apologize. These two do not represent the Swedish or Finnish cancer or radiation research community, and our media have given them far more space in the public discourse than their work merits.</p>\r\n<p>They are heavily quoted in networks of pseudoscience, including anti-vaccine sites, right-wing "alternative facts" sites and Strålskyddsstiftelsen ("Swedish Radiation Protection Foundation"), a private foundation created in 2012 with a deceptive name meant to invoke authority, which has had to be corrected on multiple occasions by the actual Swedish Radiation Safety Authority, Strålskyddsmyndigheten.</p>\r\n<p>Strålskyddsstiftelsen received the 2013 "Misleader of the Year" award from the main Swedish scientific skeptics\' society, Vetenskap och Folkbildning ("Science and Public Education") for "[their fearmongering propaganda and biased reporting on the health effects of mobile telephony use and wireless networks]".</p>\r\n<p><a href=\"https://www.vof.se/utmarkelser/tidigare-utmarkelser/aretas-forvillare-2013/\" class=\"uri\">https://www.vof.se/utmarkelser/tidigare-utmarkelser/aretas-forvillare-2013/</a> (in Swedish)</p>\r\n<p>These networks are part of a feedback loop where they get media attention, politicians pick up on their claims and use them to invoke the precautionary principle and get precautionary regulation in place, or judges rule based on the claims, which then gets quoted by these entities as evidence that they were right all along.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>I’m no cancer researcher, but neither is Rainer Nyberg, he’s a retired professor in pedagogy. He’s a concerned citizen. <a href=\"https://en.wikipedia.org/wiki/Lennart_Hardell\" class=\"uri\">https://en.wikipedia.org/wiki/Lennart_Hardell</a> 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.</p>\r\n<p>We know that high-voltage 16.7 Hz fields increase the risk for leukemia in train drivers, but we don’t know why. I am open to the poss

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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h2 id=\"server-api\">Server API</h2>\r\n<p>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.</p>\r\n<pre><code>/api/research/available ApiAvailableResearchR GET\r\n/api/research/current ApiCurrentResearchR GET POST DELETE\r\n/api/research/production ApiResearchProductionR GET</code></pre>\r\n<h2 id=\"simulation\">Simulation</h2>\r\n<p>Simulation of research is done by <code>handleFactionResearch</code>, 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 <code>completed_research</code> table. Final step is updating what research will be available in the next turn.</p>\r\n<pre><code>handleFactionResearch date faction = do\r\n production <- totalProduction $ entityKey faction\r\n current <- selectList [ CurrentResearchFactionId ==. entityKey faction ] []\r\n let updated = updateProgress production <$> current\r\n _ <- updateUnfinished updated\r\n _ <- handleCompleted date updated $ entityKey faction\r\n _ <- updateAvailableResearch $ entityKey faction\r\n return ()</code></pre>\r\n<h2 id=\"research-point-production\">Research point production</h2>\r\n<p>Research points are produced by buildings. So first step is to load all planets owned by the faction and buildings on those planets. Applying <code>researchOutput</code> function to each building yields a list of <code>TotalResearchScore</code>, which is then summed up by <code>mconcat</code>. We can use <code>mconcat</code> as <code>TotalResearchScore</code> is a monoid (I talked about these couple episodes ago).</p>\r\n<pre><code>totalProduction fId = do\r\n pnbs <- factionBuildings fId\r\n let buildings = join $ fmap snd pnbs\r\n return $ mconcat $ researchOutput . entityVal <$> buildings</code></pre>\r\n<p><code>researchOutput</code> 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 <code>ResearchComplex</code>, while second one is for <code>ParticleAccelerator</code>. Final case uses underscore to match anything and indicate that we’re not even interested on the particular value being matched. <code>mempty</code> is again from our monoid definition. It is empty or unit value of monoid, which in case of <code>TotalResearchScore</code> is zero points in all research categories.</p>\r\n<pre><code>researchOutput Building { buildingType = ResearchComplex } =\r\n TotalResearchScore\r\n { totalResearchScoreEngineering = ResearchScore 10\r\n , totalResearchScoreNatural = ResearchScore 10\r\n , totalResear

(2848,'2019-07-03','Random numbers in Haskell',1957,'Tuula talks how to generate random numbers (and other values) in Haskell','<p>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.</p>\r\n<p>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.</p>\r\n<p>First part to the puzzle is type class <code>RandomGen</code>:</p>\r\n<pre><code>class RandomGen g where\r\n next :: g -> (Int, g)\r\n genRange :: g -> (Int, Int)\r\n split :: g -> (g, g)</code></pre>\r\n<p><code>next</code> produces tuple, where first element is random <code>Int</code> and second element is new random generator. <code>genRange</code> returns tuple defining minimum and maximum values this generator will return. <code>split</code> produces tuple with two new random generators.</p>\r\n<p>Using <code>RandomGen</code> to produce random values of specific type or for specific range requires a bit of arithmetic. It’s easier to use <code>Random</code> that defines functions for that specific task:</p>\r\n<pre><code>class Random a where\r\n randomR :: RandomGen g => (a, a) -> g -> (a, g)\r\n random :: RandomGen g => g -> (a, g)\r\n randomRs :: RandomGen g => (a, a) -> g -> [a]\r\n randoms :: RandomGen g => g -> [a]\r\n randomRIO :: (a, a) -> IO a\r\n randomIO :: IO a</code></pre>\r\n<ul>\r\n<li><code>randomR</code>, when given range and random generator, produces tuple with random number and new generator</li>\r\n<li><code>random</code>, is similar but doesn’t take range. Instead it will use minimum and maximum specific to that data type</li>\r\n<li><code>randomRs</code>, takes range and produces infinite list of random values within that range</li>\r\n<li><code>randoms</code>, simply produces infinite list of random values using range that is specific to datatype</li>\r\n<li><code>randomRIO</code> and <code>randomIO</code> are effectful versions that don’t need random generator, but use some default one</li>\r\n</ul>\r\n<p>In short, <code>RandomGen</code> is source of randomness and <code>Random</code> is datatype specific way of generating random values using random generator <code>RandomGen</code>.</p>\r\n<p>Final part of the puzzle is where to get <code>RandomGen</code>? One could initialize one manually, but then it wouldn’t be random. However, there’s function <code>getStdGen</code> that will seed <code>RandomGen</code> using OS default random number generator, current time or some other method. Since it has signature of <code>getStdGen :: IO StdGen</code>, one can only call it in IO monad.</p>\r\n<p>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 <code>RandomGen</code> in effectful function and pass it to pure function.</p>\r\n<h2 id=\"example\">Example</h2>\r\n<pre><code>import System.Random\r\nimport Data.List\r\n\r\n-- | get n unique entries from given list in random order\r\n-- | if n > length of list, all items of the list will be returned\r\ngetR :: RandomGen g => g -> Int -> [a] -> [a]\r\ngetR g n xs =\r\n fmap (xs !!) ids\r\n where\r\n ids = take (min n $ length xs) $ nub $ randomRs (0, length xs - 1) g\r\n\r\n-- | Returns 4 unique numbers between 1 and 10 (inclusive)\r\ntest :: IO [Int]\r\ntest = do\r\n g <- getStdGen\r\n return $ getR g 4 [1..10]</code></pre>\r\n<h2 id=\"in-closing\">In closing</h2>\r\n<p>Pseudo randomness doesn’t require IO, only seeding the generator does. Simple computation that don’t require many calls to <code>random</code> are easy enough. If you need lots of random values, <a href=\"https://hackage.haskell.org/package/MonadRandom-0.4.1/

Further research refines it and factories are able to produce higher quality components.</p>\r\n<p>Full definition of component is show below:</p>\r\n<pre><code>data Component = Component\r\n { componentId :: ComponentId\r\n , componentLevel :: ComponentLevel\r\n , componentName :: ComponentName\r\n , componentDescription :: ComponentDescription\r\n , componentWeight :: Weight\r\n , componentSlot :: ComponentSlot\r\n , componentType :: [ ComponentPower ]\r\n , componentCost :: RawResources ResourceCost\r\n , componentChassisType :: ChassisType\r\n }\r\n deriving (Show, Read, Eq, Ord)</code></pre>\r\n<p>Two particularly interesting fields are <code>componentSlot</code> and <code>componentType</code>. <code>componentSlot</code> has type of <code>ComponentSlot</code> 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. <code>componentType</code> has type of <code>ComponentPower</code>, which defines what component does in general. It could be sensor or provide supplies for the vehicle for example.</p>\r\n<p>Technology requirements are defined by function: <code>componentRequirements :: ComponentId -> Maybe Technology</code>. It defines which technology unlock a given component. Part of the definition is show below. Each and every <code>ComponentId</code> has to be handled.</p>\r\n<pre><code>componentRequirements ShipLongRangeSensors = Just HighSensitivitySensors\r\ncomponentRequirements ShipBridge = Nothing\r\ncomponentRequirements VehicleWheeledMotiveSystem = Nothing\r\ncomponentRequirements VehicleHoverMotiveSystem = Just HoverCrafts\r\n...</code></pre>\r\n<p>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. <code>type</code> with type of <code>ChassisType</code> 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.</p>\r\n<pre><code>Chassis json\r\n name ChassisName\r\n tonnage Weight\r\n type ChassisType\r\n technology Technology Maybe\r\n armourSlots SlotAmount\r\n innerSlots SlotAmount\r\n outerSlots SlotAmount\r\n sensorSlots SlotAmount\r\n weaponSlots SlotAmount\r\n engineSlots SlotAmount\r\n motiveSlots SlotAmount\r\n sailSlots SlotAmount\r\n deriving Show Read Eq</code></pre>\r\n<p>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 tw

So this is an update on what I currently carry in my ‘Geek’ Bag when out and about.</p>\r\n<p>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:</p>\r\n<ul>\r\n<li>Lenovo X230i</li>\r\n<li>Toshiba z30</li>\r\n<li>Dells E6220 x 2, E7250, E7440 and E6540</li>\r\n</ul>\r\n<p>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.</p>\r\n<p>But all the others have their place in the bag, for demonstrating Linux Distros at events or at my LUG.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.

I found it about 3 weeks ago at <a href=\"https://www.handupthrift.com/\" target=\"_blank\">Hand-Up Thrift store</a> in Lafayette Louisiana for $5. It was in partially working condition, without a power cord, and in need of some work. I cleaned the contact points, overhauled the fast-forward idler wheel, lubricated both of the tape shafts, replaced the belts, hacked an old electric razor cord to work as a power cord, and tightened up the record linkage. One thing I still can\'t get working is recording using the microphone.</p>\r\n\r\n<p>I spend about half of this episode talking about trying to make a super-long recording fit on a 5-inch reel and playing at 4.8 cm/second. I use Kimiko Ishizaka\'s wonderful <a href=\"https://kimiko-piano.com/open-goldberg\" target=\"_blank\">Open Goldberg Variations</a> and <a href=\"https://music.kimiko-piano.com/album/bach-well-tempered-clavier-book-1\" target=\"_blank\">Open Well-Tempered Clavier</a> as the music. To do this, I speeded up all of the tracks to play at 4x speed, for which I use the following script to loop through all mp3s in the current directory and subject them to the appropriate <a href=\"https://linux.die.net/man/1/sox\" target=\"_blank\">sox</a> command:</p>\r\n\r\n<pre>\r\n#!/bin/bash\r\n\r\nfor i in *.mp3; do\r\n# speed em up 4x\r\n infile=$(basename $i)\r\n stem=$(basename \"$i\" .mp3)\r\n outfile=\"$stem\"_4x.mp3\r\n sox $infile $outfile speed 4.0\r\n sleep .1\r\ndone\r\n</pre>\r\n\r\n<p>It worked! Well. The script and <code>sox</code> 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.

(2868,'2019-07-31','Custom data with Persistent',1202,'Tuula explains how to serialize custom data with Persistent','<p>Podcast episode is about two things, serializing custom data with Persistent and <code>IsString</code> typeclass.</p>\r\n<p>I’m using Persistent in conjunction with Yesod (web framework). Process in short is that data is defined in <code>/config/models</code> 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.</p>\r\n<p>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.</p>\r\n<p>For example, following piece defines enumeration <code>BuildingType</code> that is mapped in <code>varchar</code> field in database. Enumeration is thus stored as text.</p>\r\n<pre><code>data BuildingType = SensorStation\r\n | ResearchComplex\r\n | Farm\r\n | ParticleAccelerator\r\n | NeutronDetector\r\n | BlackMatterScanner\r\n | GravityWaveSensor\r\n deriving (Show, Read, Eq)\r\n\r\nderivePersistField "BuildingType"</code></pre>\r\n<p>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.</p>\r\n<p>Our example is for <code>StarDate</code>, which is just glorified <code>Int</code>. I’m using newtype to make <code>StarDate</code> distinct from any other <code>Int</code>, even when it behaves just like <code>Int</code>.</p>\r\n<pre><code>newtype StarDate = StarDate { unStarDate :: Int }\r\n deriving (Show, Read, Eq, Num, Ord)\r\n\r\ninstance PersistField StarDate where\r\n toPersistValue (StarDate n) =\r\n PersistInt64 $ fromIntegral n\r\n\r\n fromPersistValue (PersistInt64 n) =\r\n Right $ StarDate $ fromIntegral n\r\n\r\n fromPersistValue _ =\r\n Left "Failed to deserialize"\r\n\r\n\r\ninstance PersistFieldSql StarDate where\r\n sqlType _ = SqlInt64</code></pre>\r\n<p>One more trick, that doesn’t directly relate to Persistent is <code>IsString</code> type class. Instead of having to specify all the time what type text literal is, one can let compiler to deduce it from usage.</p>\r\n<p>For example, if I had a newtype like:</p>\r\n<pre><code>newtype PlanetName = PlanetName { unPlanetName :: Text }</code></pre>\r\n<p>I can turn on OverloadedStrings pragma and create <code>IsString</code> instance:</p>\r\n<pre><code>instance IsString PlanetName where\r\n fromString = PlanetName . fromString</code></pre>\r\n<p>Now I can write: <code>placeName = "Earth"</code> instead of <code>placeName = PlanetName "Earth"</code> and compiler can deduce correct type based on how the <code>placeName</code> is used.</p>\r\n<p>Thanks for listening, if you have any questions or comments, you can reach me via email or in the fediverse, where I’m <code>Tuula@mastodon.social</code>.</p>\r\n',364,107,0,'CC-BY-SA','haskell, persistent, database',0,0,1),

They are used to defined set of functions that can operate more than one specific type of data.</p>\r\n<h2 id=\"equality\">Equality</h2>\r\n<p>In Haskell there’s no default equality, it has to be defined.</p>\r\n<p>There’s two parts to the puzzle. First is type class <code>Eq</code> that comes with the standard library and defines function signatures for equality and non-equality comparisons. There’s type parameter <code>a</code> in the definition, which is filled by user when they define instance of <code>Eq</code> for their data. In that instance definition, <code>a</code> is filled with concrete type.</p>\r\n<pre><code>class Eq a where\r\n (==) :: a -> a -> Bool\r\n (/=) :: a -> a -> Bool\r\n\r\n x /= y = not (x == y)</code></pre>\r\n<p>Definition above can be read as “class Eq a that has two functions with following signatures and implementations”. In other words, given two <code>a</code>, this function determines are they equal or not (thus <code>Bool</code> as return type). <code>/=</code> is defined in terms of <code>==</code>, 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).</p>\r\n<p>If we define our own <code>Size</code> type, like below, we can compare sizes:</p>\r\n<pre><code>data Size = Small | Medium | Large\r\n deriving (Show, Read)\r\n\r\ninstance Eq Size where\r\n Small == Small = True\r\n Medium == Medium = True\r\n Large == Large = True\r\n _ == _ = False</code></pre>\r\n<p>And here’s couple example comparisons.</p>\r\n<pre><code>> Small == Small\r\nTrue\r\n> Large /= Large\r\nFalse</code></pre>\r\n<p>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 <code>deriving (Show, Read, Eq)</code>.</p>\r\n<pre><code>data Size = Small | Medium | Large\r\n deriving (Show, Read, Eq)</code></pre>\r\n<h2 id=\"hierarchy-between-type-classes\">Hierarchy between type classes</h2>\r\n<p>There can be hierarchy between type classes, meaning one requires presence of another. Common example is <code>Ord</code>, which is used to order data.</p>\r\n<pre><code>class Eq a => Ord a where\r\n compare :: a -> a -> Ordering\r\n (<) :: a -> a -> Bool\r\n (>=) :: a -> a -> Bool\r\n (>) :: a -> a -> Bool\r\n (<=) :: a -> a -> Bool\r\n max :: a -> a -> a\r\n min :: a -> a -> a</code></pre>\r\n<p>This definition can be read as “class Ord a, where a has instance of Eq, with pile of functions as follows”. <code>Ord</code> has default implementation for quite many of these, in terms of others, so it’s enough to implement either <code>compare</code> or <code><=</code>.</p>\r\n<p>For our <code>Size</code>, instance of <code>Ord</code> could be defined as:</p>\r\n<pre><code>instance Ord Size where\r\n Small <= _ = True\r\n Medium <= Small = False\r\n Medium <= _ = True\r\n Large <= Large = True\r\n Large <= _ = False</code></pre>\r\n<h2 id=\"writing-generic-code\">Writing generic code</h2>\r\n<p>There’s lots and lots of type classes in standard library:</p>\r\n<ul>\r\n<li><code>Num</code> for numeric operations</li>\r\n<li><code>Integral</code> for integer numbers</li>\r\n<li><code>Floating</code> for floating numbers</li>\r\n<li><code>Show</code> for turning data into strings</li>\r\n<li><code>Read</code> for turning strings to data</li>\r\n<li><code>Enum</code> for sequentially ordered types (these can be enumerated)</li>\r\n<li><code>Bounded</code> for things with upper and lower bound</li>\r\n<li>and so on…</li>\r\n</ul>\r\n<p>Type classes allow you to write really generic code.

Main one is <code>Person</code>, which stores name, gender, sex, date of birth and some stats (and then some more).</p>\r\n<p>There are lots of various ways of naming people and I chose to model three for the starters:</p>\r\n<pre><code>data PersonName =\r\n RegularName FirstName FamilyName (Maybe Cognomen)\r\n | SimpleName FirstName (Maybe Cognomen)\r\n | RegalName FirstName FamilyName RegnalNumber (Maybe Cognomen)\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>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.</p>\r\n<p>Sex and gender I’m modeling with simple system of two enumerations, sex can be <code>Female</code>, <code>Male</code> or <code>Intersex</code>, while gender has values <code>Man</code>, <code>Woman</code>, <code>Agender</code> and <code>Nonbinary</code>. System is coarse, but should be enough to get started with the game. Later on, this can be expanded to more nuanced system.</p>\r\n<p>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.</p>\r\n<p>Relations are modeled as <code>PersonRelation</code> and thus stored in <code>person_relation</code> table:</p>\r\n<pre><code>Relation json\r\n originatorId PersonId\r\n targetId PersonId\r\n type RelationType\r\n visibility RelationVisibility\r\n deriving Show Read Eq</code></pre>\r\n<p>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 <code>RelationVisibility</code>, 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.</p>\r\n<p>Intel is modeled as <code>HumanIntelligence</code> and stored in <code>human_intelligence</code> table:</p>\r\n<pre><code>HumanIntelligence json\r\n personId PersonId\r\n ownerId PersonId\r\n level PersonIntel\r\n deriving Show Read Eq</code></pre>\r\n<p>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.</p>\r\n<p>Different types of intels are listed as <code>PersonIntel</code>:</p>\r\n<pre><code>data PersonIntel =\r\n Stats\r\n | Demesne\r\n | FamilyRelations\r\n | SecretRelations\r\n | Opinions OpinionIntel\r\n | Traits\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>Person related data is sent back to client in <code>PersonReport</code> record (I’m not copying it here as it’s relatively large). We can have a look on how one field is processed.</p>\r\n<p>For example, in case of traits. <code>PersonReport</code> has field <code>personReportTraits :: !(Maybe [TraitReport])</code>. 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

(2888,'2019-08-28','Pattern matching in Haskell',1236,'Tuula talks about one of their favourite features in Haskell','<p>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.</p>\r\n<p>First example is a function that takes a <code>Bool</code> and returns a respective <code>String</code>:</p>\r\n<pre><code>boolToString :: Bool -> String\r\nboolToString n =\r\n if n\r\n then "True"\r\n else "False"</code></pre>\r\n<p>Nothing too fancy, just an <code>if</code> expression inside a function. We can move that <code>if</code> out of there though and define exactly same functionality, but with patterns:</p>\r\n<pre><code>boolToString :: Bool -> String\r\nboolToString True =\r\n "True"\r\n\r\nboolToString False =\r\n "False"</code></pre>\r\n<p>There’s one definition for <code>boolToString</code>, but two different patterns used.</p>\r\n<p>Second example is bit more complex, this time we have <code>Maybe Int</code> that is being turned into <code>String</code>. <code>Maybe</code> has two value constructors <code>Nothing</code> and <code>Just a</code>. We have two cases for <code>Just</code>, specific one for when it’s <code>Just 1</code> and more general one <code>Just n</code> that takes care of rest of the cases.</p>\r\n<pre><code>isBig :: Maybe Int -> String\r\nisBig Nothing =\r\n "Not at all"\r\n\r\nisBig (Just 1) =\r\n "Just perfect"\r\n\r\nisBig (Just n) =\r\n if n < 10\r\n then "Just slightly"\r\n else "Definitely is"</code></pre>\r\n<p>Some example usage:</p>\r\n<pre><code>> isBig Nothing\r\n"Not at all"\r\n> isBig $ Just 0\r\n"Just perfect"\r\n> isBig $ Just 50\r\n"Definitely is"</code></pre>\r\n<p>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:</p>\r\n<pre><code>data Customer = Customer\r\n { customerName :: String\r\n , customerDiscountPct :: Double\r\n , vipCustomer :: Bool\r\n }\r\n\r\ntotalFee :: Double -> Customer -> Double\r\ntotalFee bill cust@(Customer { vipCustomer = True }) =\r\n bill * 0.9 * customerDiscountPct cust\r\n\r\ntotalFee bill cust =\r\n bill * customerDiscountPct cust</code></pre>\r\n<p>There’s two cases of <code>totalFee</code> function. First one is for when passed in <code>Customer</code> has <code>vipCustomer</code> field <code>True</code>. Second one takes care of general case. In the first case we’re using <code>@</code> to bind <code>Customer</code> as a whole to <code>cust</code> name.</p>\r\n<p>Lists can be matched too. The basic idea is exactly the same:</p>\r\n<ul>\r\n<li><code>(x:xs)</code> matches a list with at least one item, <code>x</code> is first item, <code>xs</code> is rest of the items (might be an empty list)</li>\r\n<li><code>(x:y:_)</code> matches two first items in a list of at least two items, <code>x</code> is first, <code>y</code> is second, <code>_</code> is rest</li>\r\n<li><code>[]</code> matches empty list</li>\r\n<li><code>(x:[])</code> matches list of exactly one item</li>\r\n</ul>\r\n<p>Underscore <code>_</code> 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.</p>\r\n<p>Next example is recursively counting amount if items in a list using pattern matching:</p>\r\n<pre><code>count :: [a] -> Int\r\ncount [] =\r\n 0\r\n\r\ncount (x:xs) =\r\n 1 + count xs</code></pre>\r\n<p>Fibonacci

This episode has somewhat more code than previous one, so following along with the shownotes might be a good idea. I’m trying to minimize amount of code I read out aloud.</p>\r\n<h2 id=\"intro\">Intro</h2>\r\n<p>One person’s opinion of another is expressed as <code>OpinionScore</code> that ranges from -100 to 100.</p>\r\n<p>Computing the score is based on intelligence player has available to them. Internally we have <code>ReportResult</code> that tracks score, reasons for the score and confidence level about the results. It’s defined as:</p>\r\n<pre><code>data ReportResult =\r\n FeelingLevel OpinionScore\r\n | ReasonsLevel OpinionScore [OpinionReason]\r\n | DetailedLevel OpinionScore [OpinionReason]\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>We’re going to be adding up these results quite a bit, so we define <code>SemiGroup</code> and <code>Monoid</code> instances for it. 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:</p>\r\n<pre><code>instance Semigroup ReportResult where\r\n (FeelingLevel s1) <> (FeelingLevel s2) = FeelingLevel (s1 <> s2)\r\n (FeelingLevel s1) <> (ReasonsLevel s2 _) = FeelingLevel (s1 <> s2)\r\n (FeelingLevel s1) <> (DetailedLevel s2 _) = FeelingLevel (s1 <> s2)\r\n (ReasonsLevel s1 _) <> (FeelingLevel s2) = FeelingLevel (s1 <> s2)\r\n (ReasonsLevel s1 r1) <> (ReasonsLevel s2 r2) = ReasonsLevel (s1 <> s2) (r1 <> r2)\r\n (ReasonsLevel s1 r1) <> (DetailedLevel s2 r2) = ReasonsLevel (s1 <> s2) (r1 <> r2)\r\n (DetailedLevel s1 _) <> (FeelingLevel s2) = FeelingLevel (s1 <> s2)\r\n (DetailedLevel s1 r1) <> (ReasonsLevel s2 r2) = ReasonsLevel (s1 <> s2) (r1 <> r2)\r\n (DetailedLevel s1 r1) <> (DetailedLevel s2 r2) = DetailedLevel (s1 <> s2) (r1 <> r2)\r\n\r\n\r\ninstance Monoid ReportResult where\r\n mempty = DetailedLevel mempty mempty</code></pre>\r\n<h2 id=\"opinion-based-on-traits\">Opinion based on traits</h2>\r\n<p>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 <code>traitPairOpinion</code> function, which definition I’m omitting as it’s rather long and not too interesting. It’s signature is: <code>traitPairOpinion :: TraitType -> TraitType -> Maybe (OpinionScore, OpinionReason)</code>. So, given two traits, tells how that pair affects to opinion and reasoning for it.</p>\r\n<p>In order to have nicer format for out data, we introduce a helper function:</p>\r\n<pre><code>traitPairScore :: TraitType -> TraitType -> (OpinionScore, [OpinionReason])\r\ntraitPairScore a b =\r\n case traitPairOpinion a b of\r\n Nothing ->\r\n mempty\r\n\r\n Just (s, r) ->\r\n (s, [r])</code></pre>\r\n<p>This is because <code>(OpinionScore, OpinionReason)</code> isn’t monoid, but <code>(OpinionScore, [OpinionReason])</code> is, which means we can combine them with <code><></code>.</p>\r\n<p>Actual score calculation based on traits, we do it like this:</p>\r\n<pre><code>traitScore :: [TraitType] -> [PersonIntel] -> [TraitType] -> [PersonIntel] -> ReportResult\r\ntraitScore originatorTraits originatorIntel targetTraits targetIntel =\r\n if (Traits `elem` originatorIntel) && (Traits `elem` targetIntel)\r\n then DetailedLevel score reasons\r\n else FeelingLevel score\r\n where\r\n (score, reasons) = mconcat $ traitPairScore <$> originatorTraits <*> targetTraits</code></pre>\r\n<p>The interesting part is <code>mconcat $ traitPairScore <$> originatorTraits <*> targetTraits</code>.

(2903,'2019-09-18','What is PMEM',453,'Persistent memory (PMEM), also known as storage-class memory','<h3 id=\"what-is-persistent-memory\">What is persistent memory?</h3>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<h3 id=\"persistent-memory-benefits\">Persistent Memory Benefits</h3>\r\n<p>Persistent memory in the data center allows applications to run without incurring the latency penalty of going out to storage.</p>\r\n<p>The main advantages of persistent memory include:</p>\r\n<ul>\r\n<li>Provides access latencies less than those of flash SSDs.</li>\r\n<li>Increases throughput more than flash storage.</li>\r\n<li>Cheaper than DRAM.</li>\r\n<li>PMEM is cacheable. This is a huge advantage over PCIe interconnect, which cannot be cached in the CPU.</li>\r\n<li>Real-time access to data; allows ultrafast access to large datasets.</li>\r\n<li><p>Data persists in memory after power interruption, like flash.</p></li>\r\n<li>Persistent Memory Use Cases\r\n<ul>\r\n<li>Fraud detection</li>\r\n<li>Cyberthreat analysis</li>\r\n<li>Web-scale personalization</li>\r\n<li>Financial trading</li>\r\n<li>Internet of Things (IoT)</li>\r\n</ul></li>\r\n</ul>\r\n<pre><code> Non \\\r\n Volatile /- Non-volatile: you plug it off and on again, and the Information is still there\r\n\r\n Double \\\r\n In-line | DIMM: This the HW format\r\n Memory |\r\n Module /</code></pre>\r\n<h3 id=\"persistent-memory-vs.-nvram\">Persistent Memory Vs. NVRAM</h3>\r\n<p>Nonvolatile random-access memory (NVRAM) is random-access memory that retains its information even if there is no power. 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.

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.</p>\r\n<p>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.</p>\r\n<p>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.<br />\r\nMy full review is on the Distrohoppers Blog as is a link to the Audio of the show.</p>\r\n<p>That’s it for this time, this is Tony Hughes saying goodbye until next time.</p>\r\n<p><a href=\"https://distrohoppersdigest.blogspot.com/\" class=\"uri\">https://distrohoppersdigest.blogspot.com/</a></p>\r\n<p><a href=\"https://endeavouros.com/\" class=\"uri\">https://endeavouros.com/</a></p>\r\n<p><a href=\"https://www.archlinux.org/\" class=\"uri\">https://www.archlinux.org/</a></p>\r\n',338,0,0,'CC-BY-SA','EndeavourOS, Linux, Arch Linux, Distrohopping',0,0,1),

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.

(2918,'2019-10-09','Selecting random item from weighted list',1604,'How to selected random item from weighted list using Haskell','<h2 id=\"intro\">Intro</h2>\r\n<p>We’re going to have a look how to select random item from weighted list. There isn’t that much code this time, but it certainly took many tries to get it working and looking nice.</p>\r\n<h2 id=\"analogy\">Analogy</h2>\r\n<p>Imagine stack of building blocks of different heights stacked on top of each other. 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.</p>\r\n<h2 id=\"explanation-of-algorithm\">Explanation of algorithm</h2>\r\n<p>We have list of items and associated weight, defined as <code>Frequency a = Frequency Int a</code>.</p>\r\n<p>Total is sum of all the weights and we select a random number <code>n</code> between 1 and total.</p>\r\n<p><code>pick</code> function has signature of <code>[Frequency a] -> n -> Maybe a</code>. Empty list will result <code>Nothing</code>. When picking item, if <code>n</code> 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 <code>n</code> and try again. Eventually we either arrive to item which weight is greater than <code>n</code> or to empty list.</p>\r\n<h2 id=\"quick-detour-on-random-number-generators\">Quick detour on random number generators</h2>\r\n<p>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.</p>\r\n<p>Passing these random number generators around in code gets tedious, but there’s different solution: <code>MonadRandom</code>. 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: <code>getRandomR :: Random a => (a, a) -> m a</code>. Given a lower and upper bound, it will return you a random value wrapped in context that carries that new random number generator.</p>\r\n<p>In the end, we need to take our computation (that can be complex and use multiple calls to random number generator) and turn that <code>m a</code> into <code>a</code>. This is done with <code>runRand :: RandomGen g => Rand g a -> g -> (a, g)</code>. We give it our computation and a <code>RandomGen g</code> that can generate random values and receive <code>(a, g)</code> where <code>a</code> is our result and <code>g</code> new random number generator. In cases where we aren’t going to use the new generator, we can use <code>evalRand :: RandomGen g => Rand g a -> g -> a</code>, which discards it and returns just <code>a</code>.</p>\r\n<h2 id=\"actual-implementation-with-explanation\">Actual implementation with explanation</h2>\r\n<p>First, <code>Frequency</code> for expressing weight of individual item. It’s parametrized, so can be used with any data.</p>\r\n<pre><code>data Frequency a = Frequency Int a\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>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 <code>Nothing</code>, otherwise with <code>Just a</code>. 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.</p>\r\n<pre><code>pick :: [Frequency a] -> Int -> Maybe a\r\npick []

(2928,'2019-10-23','Building markov chains with Haskell',1798,'How to build markov chains with Haskell','<h2 id=\"intro\">Intro</h2>\r\n<p>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.</p>\r\n<h2 id=\"configuration\">Configuration</h2>\r\n<p>We’re after generic system, hence parametrized data types.</p>\r\n<p>First part is <code>Configuration a</code> that lists possible starting elements of chain and elements that can follow a particular element.</p>\r\n<pre><code>data Config a = Config\r\n { configStarts :: ![Item a]\r\n , configContinuations :: !(Map a [Item a])\r\n } deriving (Show, Read, Eq)</code></pre>\r\n<p>Second part is <code>Item a</code>, that just holds single item that could appear in chain and relatively frequency for its appearance.</p>\r\n<pre><code>data Item a =\r\n Item (Frequency (Maybe a))\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p>We’re using <code>Maybe a</code> as in some cases there’s chance of element being last element in chain. Thus, <code>Nothing</code> will represent end of chain.</p>\r\n<p>In previous episode, we implemented <code>choose</code>, but later on I decided to rename it to <code>chooseM</code>. So when you see <code>chooseM</code>, it’s just different name for what we implemented previously.</p>\r\n<h2 id=\"building-a-chain\">Building a chain</h2>\r\n<p>Since building a configuration depends on the case quite a bit, we’re just going to assume that we have one at hand.</p>\r\n<p>Our chains are built by <code>chainM :: (Ord a, RandomGen g) => Config a -> Rand g [a]</code>. Given a config, it creates computation that when run will return list of <code>a</code>, which is our chain.</p>\r\n<p>Implementation is fairly straightforward:</p>\r\n<pre><code>chainM config = do\r\n starter <- chooseM (itemToFreq <$> configStarts config)\r\n case join starter of\r\n Nothing ->\r\n return []\r\n\r\n Just h -> do\r\n t <- tailOfChain config h\r\n return $ h : t</code></pre>\r\n<p>First we select item from starting elements. In case there isn’t one, result will be a empty list. Otherwise we use <code>tailOfChain</code> to compute rest of the list and return a list of starter element followed by that tail.</p>\r\n<p>For tail we need to figure out first what possible elements there are that can follow a given element. This is done by <code>candidates</code> function. <code>lookup</code> finds a possible list of elements in <code>configContinuations</code>. We use <code>itemToFreq</code> to turn this list into frequencies. Since <code>items</code> might be <code>Nothing</code> (in case where there aren’t any suitable continuations present) and any continuation in the list might be <code>Nothing</code> (in case where this is possibly terminating element), we have to use <code>(fmap . fmap)</code> to apply <code>itemToFreq</code> to each possible element. Moreover, <code>concat</code> turns our <code>Maybe [Frequency (Maybe a)]</code> into <code>[Frequency (Maybe a)]</code>, if we have <code>Nothing</code> at this stage, result will be an empty list <code>[]</code>.</p>\r\n<pre><code>candidates :: (Ord a) => Config a -> a -> [Frequency (Maybe a)]\r\ncandidates config x =\r\n concat $ (fmap . fmap) itemToFreq items\r\n where\r\n items = lookup x (configContinuations config)</code></pre>\r\n<p>That <code>concat</code> part could have been written as:</p>\r\n<pre><code> case (fmap . fmap) itemToFreq items of\r\n Nothing ->\r\n []\r\n\r\n Just x ->\r\n x</code></pre>\r\n<p>and the end result would be identical.</p>\r\n<p>Now that we know how to figure our possible continuation elements, we can implement computing tai

(2938,'2019-11-06','Naming pets in space game',1236,'How to use markov chains to generate names','<h2 id=\"intro\">Intro</h2>\r\n<p>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.</p>\r\n<h2 id=\"idea\">Idea</h2>\r\n<p>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.</p>\r\n<h2 id=\"config\">Config</h2>\r\n<p>While we’re not going to dig very deep into making configurations for markov chains, we can have look at the overall process.</p>\r\n<p>We have list of names to serve as examples and three functions, which implementation I won’t delve into:</p>\r\n<ul>\r\n<li><code>start</code> for adding starting element</li>\r\n<li><code>links</code> for recording link between two elements</li>\r\n<li><code>end</code> adds ending element</li>\r\n</ul>\r\n<p><code>addName</code> function is used to add single name into config:</p>\r\n<pre><code>addName :: Int -> Text -> Config Text -> Config Text\r\naddName n s config =\r\n links pairs $\r\n end elements $\r\n start elements config\r\n where\r\n elements = chunksOf n s\r\n pairs = zip elements (safeTail elements)</code></pre>\r\n<p>First <code>s</code> (name) is split into strings of length <code>n</code>. These <code>elements</code> 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.</p>\r\n<p>We can then fold a list of examples into config:</p>\r\n<pre><code>nameConfig :: [Text] -> Int -> Config Text\r\nnameConfig xs n =\r\n foldr (addName n) emptyConfig xs</code></pre>\r\n<p>This starts with <code>emptyConfig</code> and calls <code>addName</code> repeatedly until all elements of list containing examples have been processed.</p>\r\n<h2 id=\"implementation\">Implementation</h2>\r\n<p>Now that we have configuration, we can start generating names. As usual, I like to keep things specific and generate <code>PetName</code> instead of just <code>Text</code>. 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.</p>\r\n<p>General implementation of generating infinite list of strings of specific kind is shown below:</p>\r\n<pre><code>names :: (RandomGen g, Eq b) => (Text -> b) -> Config Text -> g -> [b]\r\nnames t config g =\r\n nub $ (t . toTitle . concat) <$> chains config g</code></pre>\r\n<p>It’s easier to read if you start from right. <code>chains config g</code> generates infinite list of markov chains with given configuration. Next we create a new function <code>(t . toTitle . concat)</code>, which uses <code>concat</code> to combine list of <code>Text</code> into single <code>Text</code>, <code>toTitle</code> to capitalize is correctly and <code>t</code> to transform it to something (<code>PetName</code> in our case). <code><$></code> is then used to apply this function to each element of our infinite list. Finally <code>nub</code> is used to remove duplicate entries.</p>\r\n<p>With <code>names</code> we can then define <code>petNames</code>:</p>\r\n<pre><code>petNames :: (RandomGen g) => g -> [PetName]\r\npetNames =\r\n names MkPetName greekNameConfig</code></pre>\r\n<p><code>MkPetName</code> is value constructor that turns <code>Text</code> into <code>PetName</code> (this is <code>t</code> used by <code>names</code> function).</p>\r\n<h2 id=\"pets\">Pets

(2948,'2019-11-20','Testing with Haskell',2560,'Introduction on HSpec and QuickCheck','<h2 id=\"intro\">Intro</h2>\r\n<p>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.</p>\r\n<h2 id=\"hspec\">HSpec</h2>\r\n<p>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.</p>\r\n<pre><code>spec :: Spec\r\nspec = do\r\n describe "Very important feature" $ do\r\n it "Execution should be error free" $ do\r\n ...\r\n\r\n it "Flux capacitors can be charged" $ do\r\n ...\r\n\r\n describe "Somewhat less important feature" $ do\r\n ...</code></pre>\r\n<h2 id=\"unit-test\">Unit test</h2>\r\n<p>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:</p>\r\n<pre><code>spec :: Spec\r\nspec = do\r\n describe "Markov chain configuration" $ do\r\n it "Adding new starting element to empty configuration creates item with frequency of 1" $ do\r\n let config = addStart ("AA" :: DT.Text) emptyConfig\r\n config ^? (configStartsL . _head . itemFreqL) `shouldBe` Just 1\r\n config ^? (configStartsL . _head . itemItemL . _Just) `shouldBe` Just "AA"\r\n\r\n it "Adding same element twice to empty configuration creates item with frequency of 2" $ do\r\n let config = addStart "AA" $\r\n addStart ("AA" :: DT.Text) emptyConfig\r\n config ^? (configStartsL . _head . itemFreqL) `shouldBe` Just 2\r\n config ^? (configStartsL . _head . itemItemL . _Just) `shouldBe` Just "AA"</code></pre>\r\n<p>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.</p>\r\n<p>Both tests use lenses for reading nested data structure. Episode doesn’t cover them much at all, as it’s enough to know that <code>(configStartsL . _head . itemFreqL)</code> 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.</p>\r\n<p>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.</p>\r\n<h2 id=\"property-based-test\">Property based test</h2>\r\n<p>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:</p>\r\n<pre><code>spec :: Spec\r\nspec = do\r\n describe "planets" $ do\r\n describe "food" $ do\r\n it "food requirement for positive amount of population is more than zero" $ do\r\n forAll positivePopulation $ \\x -> foodRequirement x > RawResource 0\r\n\r\n it "food base production for farms is equal or greater than their amount" $ do\r\n forAll someFarms $ \\x -> (sum (fmap foodBaseProduction x)) > (RawResource $ length x)</code></pre>\r\n<p>Above we have two tests. First one checks that with any non-zero population, <code>foodRequirement</code> is greater than 0. Second one check that with any positive amount of farm, <code>foodBaseProduction</code> is greater than amount of the farms.</p>\r\n<p><code>positivePopulation</code> is Generator, that is used by QuickCheck to generate random data for testing. Its definition is shown below:</p>\r\n<pre><co

I went back to the computer and read the announcement<br>\r\nin the IRC Logs and confirmed the news. Some dude I had never met, never<br>\r\nseen in my life, and didn’t even know his real name, was gone and I was<br>\r\nin the back room crying my eyes out.</p>\r\n<p>Crying for the loss of a friend.</p>\r\n<p>When had he become a friend ?</p>\r\n<p>People have been socializing since the dawn of humans, be it at the camp<br>\r\nfire, the forge, pub, hairdresser, sports club, church, or wherever.</p>\r\n<p>For us it was via Linux podcasting. You are there because you share a<br>\r\ncommon interest. If you were into Linux podcasting then you could not<br>\r\nhelp but get to know fiftyonefifty. The guy turned up everywhere if not<br>\r\non the podcasts themselves he was commenting on them. I have 619<br>\r\nmessages from him about HPR alone.</p>\r\n<p>He submitted his first show back in 2010 and has been a regular since<br>\r\nthen. At some point after that I knew that he was on my “special list”<br>\r\nof people who I could rely upon to fill the queue if needed.</p>\r\n<p>And as I sat there crying I realized that he had also sneaked onto my<br>\r\nlist of friends.</p>\r\n<p>I’ve not always been a fan of the New Year Show, but now I am glad for<br>\r\nit. While I may never get to share a beer with him any more, or take him<br>\r\nup on his promise to let me fire off some rounds on his farm, I did at<br>\r\nleast get to shoot the breeze with him for many a happy hour.</p>\r\n<p>Goodbye old friend you will be missed</p>\r\n<p><strong>Anonymous</strong><br>\r\nA Ramble for FiftyOneFifty: King of Ramblers</p>\r\n<p>I am writing a Ramble for a man I knew only as FiftyOneFifty. I never knew his real name,<br>\r\nnor do I know if he knew mine. In many things, Names do not matter, People, Actions, and<br>\r\nfeeling do. We podcasted together off and on, over several years. I don’t recall exactly<br>\r\nhow many. It doesn’t matter now, since they are all that there will ever be. We grew to be<br>\r\ngood friends. I never met him in person, online life is like that. I only know my life would be<br>\r\nmuch poorer, if I had not known him. Hearing he died, shattered me. This Ramble is my try<br>\r\nat putting most the pieces back in place. Of course, nothing can replace the largest piece,<br>\r\nthe Man Himself.

(2926,'2019-10-21','Full Circle Magazine',181,'Just a short show to request support for one of the Linux communities longest standing Magazines','<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>All the best for now.</p>\r\n<h2 id=\"links\">Links</h2>\r\n<ul>\r\n<li><a href=\"https://www.woodbrooke.org.uk/\" class=\"uri\">https://www.woodbrooke.org.uk/</a></li>\r\n<li><a href=\"https://fullcirclemagazine.org/\" class=\"uri\">https://fullcirclemagazine.org/</a></li>\r\n<li><a href=\"https://fullcirclemagazine.org/issue-149/\" class=\"uri\">https://fullcirclemagazine.org/issue-149/</a></li>\r\n</ul>\r\n',338,0,0,'CC-BY-SA','Full Circle Magazine, Ubuntu, Linux, Free Magazine, Creative Commons',0,0,1),

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.</p>\r\n<p>Mimblewimble is a new protocol that uses cryptography to achieve striking reductions in blockchain size, so users can run a full node on low powered devices like phones. 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.</p>\r\n<p>We’re not going to focus on the cryptography, although it’s a fascinating example of just how much progress is being made in recent years. We’ll focus instead on what makes this mysterious network protocol unique among cryptocurrencies.</p>\r\n',379,110,0,'CC-BY-SA','blockchain, privacy',0,0,1),

(2958,'2019-12-04','Haskell modules',1387,'Tuula talks about haskell modules','<p>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.</p>\r\n<h2 id=\"defining\">Defining</h2>\r\n<p>Each module is defined in separate file. In our example, we have file called <code>multiplexer.hs</code>, which contains our module definition.</p>\r\n<p>At the beginning of the file, we have following:</p>\r\n<pre><code>module Multiplexer (mix, match, Plexer, Scooper(..))\r\n where\r\n ....</code></pre>\r\n<p>We’re omitting actual function and type definitions as they aren’t important to this episode. In any case, there’s two functions: <code>mix</code> and <code>match</code> and two types: <code>Plexer</code> and <code>Scooper</code> that module exports (that is, these are available outside of the module). <code>Plexer</code> is imported as a type only and <code>Scooper</code> with field accessors or value constructors depending if it’s a record or algebraic datatype.</p>\r\n<h2 id=\"using-modules\">Using modules</h2>\r\n<p>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 <code>main.hs</code> that defines entry point for our program and we would like to import the definitions from <code>Multiplexer</code> module.</p>\r\n<p>Easiest one is to just have <code>import Multiplexer</code> at the start of the <code>main</code>. This brings all exported identifiers from <code>Multiplexer</code> and we can then use them. Both qualified and unqualified names are imported. Qualified means name is prepended with module name: <code>Multiplexer.mix</code> instead of just <code>mix</code>.</p>\r\n<p>If we want, we can specify what exactly should be imported: <code>import Multiplexer (mix, match)</code>. This causes only functions <code>mix</code> and <code>match</code> be imported, while <code>Plexer</code> and <code>Scooper</code> are unavailable for us. Again, both qualified and unqualified names are imported.</p>\r\n<p>In case we want only qualified names, we’ll write <code>import qualified Multiplexer</code>. After this <code>mix</code> isn’t available, but <code>Multiplexer.mix</code> is (and all the other identifiers exported by <code>Multiplexer</code>).</p>\r\n<p>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 <code>import Multiplexer as M</code>. After this, instead of <code>Multiplexer.mix</code> you write <code>M.mix</code>.</p>\r\n<p>Final thing I’m going to mention is importing everything else except specified identifiers. This is done by writing <code>import Multiplexer hiding (mix)</code>. This imports everything exported by <code>Multiplexer</code>, except <code>mix</code>.</p>\r\n<h2 id=\"summary\">Summary</h2>\r\n<p>There are many ways of importing and they can be mixed. Here’s a list of them:</p>\r\n<ul>\r\n<li><code>import Multiplexer</code></li>\r\n<li><code>import Multiplexer ()</code></li>\r\n<li><code>import Multiplexer (mix, match, Plexer, Scooper(..))</code></li>\r\n<li><code>import qualified Multiplexer</code></li>\r\n<li><code>import qualified Multiplexer (mix, match, Plexer, Scooper(..))</code></li>\r\n<li><code>import Multiplexer hiding (mix, match)</code></li>\r\n<li><code>import qualified Multiplexer hiding (Plexer, Scooper)</code></li>\r\n<li><code>import Multiplexer as M</code></li>\r\n<li><code>import Multiplexer as M (mix, match)</code></li>\r\n<li><code>import qualified Multiplexer as M</code></li>\r\n<li><code>import qualified Multiplexer as M (Plexer, Scooper(..))</code></li>\r\n</ul>\r\n<p>In short:</p>\r\n<ul>\r\n<li>Some identifiers can be chosen to be imported, while leaving others unimported</li>\r\n<li>Modules can be imported qualified (forcing an obligatory namespace qualifier to imported identi

(2966,'2019-12-16','World of Commodore 2019 Episode 1: The Interviews',1174,'In this first episode, I interview exhibitors and members at the World of Commodore in 2019.','<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<ul>\r\n<li><a href=\"https://www.tpug.ca/\" class=\"uri\">https://www.tpug.ca/</a></li>\r\n<li><a href=\"https://signalsfromspace.ca/\" class=\"uri\">https://signalsfromspace.ca/</a></li>\r\n<li><a href=\"https://doublesidedgames.com/\" class=\"uri\">https://doublesidedgames.com/</a></li>\r\n<li><a href=\"https://pquirk.com/2019/12/08/world-of-commodore-2019-episode-1/\" class=\"uri\">https://pquirk.com/2019/12/08/world-of-commodore-2019-episode-1/</a></li>\r\n</ul>\r\n',383,103,0,'CC-BY-SA','Commodore,PET,Amiga,Gecko,retro',0,0,1),

The series was recorded in one go and split into multiple parts. This last section is pretty short; it covers the main program section at the bottom of my script that calls all the other functions and allows the user to quit the program. In this episode I also mention explanatory notes that I included in my script. These are mainly for my own benefit so I could remember how I set up lirc. I’ve included these notes at the end of these show notes.</p>\r\n<p><b>Main program</b><br />\r\nTurn LCD backlight on, print <em>System up</em> message to LCD, wait a few seconds then clear screen. Activate push buttons on control and display board. Activates various IR buttons waiting on input from the remote control. Print quit message to terminal, waiting for input, repeat message until q is entered by user. When q is entered deactivate buttons and turn LCD backlight off.</p>\r\n<p>Below are my Lirc explanatory comments at the end of my Python script.</p>\r\n<blockquote>\r\n<p><code>lirc</code><br />\r\nThis is the Linux IR control program<br />\r\nLIRC (Linux Infrared remote control) is an open source package that allows users to receive and send infrared signals with a Linux-based computer system.</p>\r\n<p><code>Irrecord</code><br />\r\nTool used to record valid IR codes from your remote control. It generates the file <code>/etc/lirc/lircd.conf</code>, possibly overwrites original file so use with caution. It attempts to recognise your remote control from a series of button pushes. If the remote is not recognised then it captures the codes in raw mode, I abandoned this tool and got a valid IR file for a very similar remote control on the internet, see info below</p>\r\n<p><code>/etc/lirc/lircd.conf</code><br />\r\nFile used to store IR codes for your remote control, either using the tool <code>irrecord</code> or from somewhere on the internet. This file is a direct copy of file <code>\"BN59-00861A-SAMSUNG-TV.conf\"</code> I added the Samsung TV string to the file name.</p>\r\n<p><code>irw</code><br />\r\nTool used to get the key names for your particular remote control, for this to work you must first have a valid <code>/etc/lirc/lircd.conf</code> file</p>\r\n<p><code>~/.lircrc</code><br />\r\nThis file is used to store the remote control key names that you want to activate, and what action is to be taken when the button is pushed. Adding the field <code>\"remote =\"</code> allows the use of multiple remote controls. The remote control key names can be found by using the command <code>\"irw\"</code>, I created a file called <code>~/scripts/remote-key-names-sorted.txt</code> to store the valid key names for my Samsung remote control</p>\r\n<p><code>~/scripts/remote-key-names-sorted.txt</code><br />\r\nList of valid remote control key names for my Samsung remote control, this was generated using the <code>irw</code> command.

(3014,'2020-02-20','A Headless Raspberry Pi Streaming Radio',1068,'I use a Raspberry Pi to make a streaming radio device for my pillow speaker.','<p>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 <a href=\"https://www.raspberrypi.org/products/raspberry-pi-2-model-b/\">Raspberry Pi 2 Model B</a> with <a href=\"https://ubuntu.com/download/raspberry-pi\">Ubuntu Server</a>. 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 <a href=\"https://www.downloadhelper.net/\">Video Download Helper</a> to reveal the URL on a page with media playing (in this case it’s from TuneIn):</p>\r\n\r\n<pre><code>https://XX.XXX.XXX.XXX/radio-stationmp3-48?session-id=af1b271fefba04b650f8e253c6b253bd&source=TuneIn\r\n</code></pre>\r\n\r\n<p>Strip off everything after the <code>48</code> to get raw URL:</p>\r\n\r\n<pre><code>https://XX.XXX.XXX.XXX/radio-stationmp3-48\r\n</code></pre>\r\n\r\n<p>Command to play stream with <a href=\"https://www.mpg123.de/\">mpg123</a> on the Pi.

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 <a href=\"https://play.google.com/store/apps/details?id=org.connectbot&hl=en_US\">ConnectBot</a>. Once I’m into the Pi I run the radio commands from CLI like <code>espn</code> or <code>kmfa</code> or <code>krvs</code>. To stop playback I kill the process with <code>pkill mpg</code>. 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 <a href=\"https://smile.amazon.com/gp/product/B005GUQ0FI/\">FM transmitter</a>, so that I can use an FM radio to listen to the stream while I’m walking around the house.</p>\r\n\r\n<p>Click the image below to see pictures of the setup.</p>\r\n\r\n<p><a data-flickr-embed=\"true\" href=\"https://www.flickr.com/photos/137675441@N05/albums/72157712927722077\" title=\"Raspberry Pi Radio\"><img src=\"https://live.staticflickr.com/65535/49473218252_39195601ed.jpg\" width=\"500\" height=\"281\" alt=\"Raspberry Pi Radio\"></a></p>\r\n\r\n<h3 id=\"links\">Links</h3>\r\n\r\n<ul>\r\n<li><a href=\"https://www.raspberrypi.org/products/raspberry-pi-2-model-b/\">Raspberry Pi 2 Model B</a></li>\r\n<li><a href=\"https://ubuntu.com/download/raspberry-pi\">Ubuntu Server</a></li>\r\n<li><a href=\"https://www.downloadhelper.net/\">Video Download Helper</a> (Firefox extension)</li>\r\n<li>The <a href=\"https://smile.amazon.com/gp/product/B001MSS6CS/\">USB Audio interface</a> I use</li>\r\n<li>Panda Wireless <a href=\"https://smile.amazon.com/gp/product/B00762YNMG\">USB WiFi adapter</a></li>\r\n<li><a href=\"https://www.mpg123.de/\">mpg123</a> command-line audio player</li>\r\n<li><a href=\"https://play.google.com/store/apps/details?id=org.connectbot&hl=en_US\">ConnectBot</a></li>\r\n<li><a href=\"https://smile.am

(3013,'2020-02-19','Bash Tips - 21',2497,'Environment variables','<h2 id=\"the-environment-more-collateral-bash-tips\">The Environment <small><small>(More collateral Bash tips)</small></small></h2>\r\n<h3 id=\"overview\">Overview</h3>\r\n<p>You will probably have seen references to <em>The Environment</em> in various contexts relating to shells, shell scripts, scripts in other languages and compiled programs.</p>\r\n<p>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 <em>environment</em>. This is a list of name-value pairs, of the form <code>name=value</code>.</p>\r\n<h4 id=\"using-the-environment\">Using the environment</h4>\r\n<p>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 <code>\'HOME\'</code>, which is set to the current user’s home directory and <code>\'PWD</code>, 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.</p>\r\n<p>The environment contains global data which is passed down to subprocesses (<em>child</em> processes) by copying. However, it is not possible for a subprocess to pass information <b>back</b> to the superior (<em>parent</em>) process.</p>\r\n<h4 id=\"viewing-the-environment\">Viewing the environment</h4>\r\n<p>You can view the environment in a number of ways.</p>\r\n<ul>\r\n<li><p>From the command line the command <code>printenv</code> can do this (this is usually but not always a stand-alone command: it’s <code>/usr/bin/printenv</code> on my Debian system). We will look at this command later.</p></li>\r\n<li><p>The command <code>env</code> without any arguments does the same thing as <code>printenv</code> 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.</p></li>\r\n<li><p>Scripting languages like <code>awk</code> (as well as Python and Perl, to name just a few) can view and manipulate the environment.</p></li>\r\n<li><p>Compiled languages such as <code>C</code> can do this too of course.</p></li>\r\n<li><p>There are other commands that will show the environment, and we will look at some of these briefly.</p></li>\r\n</ul>\r\n<h4 id=\"changing-variables-in-the-environment\">Changing variables in the environment</h4>\r\n<p>The variables in the environment are not significantly different from the <em>shell parameters</em> we have seen throughout this Bash Tips series. The only difference is that they are marked for <em>export</em> to commands and sub-shells. You will often see variables (or parameters) in the environment referred to as <em>environment variables</em>. 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.</p>\r\n<p>The standard variables in the environment have upper-case names (<code>HOME</code>, <code>SHELL</code>, <code>PWD</code>, 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.</p>\r\n<p>Variables can be created and changed a number of ways.</p>\r\n<ul>\r\n<li>They can be set up at login time (globally or locally) through various standard configuration files. It is intended to look at this subject in an upcoming episode so we will leave discussing the subject until then.</li>\r\n<li>By preceding the command or script invocation with <em>name=value</em> expressions which will temporarily place these variables into the environment for the command</li>\r\n<li

(3020,'2020-02-28','Validating data in Haskell',1500,'Tuula talks about wow to validate incoming http request before acting on them','<h1 id=\"background\">Background</h1>\r\n<p>The space game I working on needs a admin interface that can by used by game masters to view and modify the simulation.</p>\r\n<p>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.</p>\r\n<pre><code>/api/admin/people AdminApiPeopleR GET\r\n/api/admin/people/#PersonId AdminApiPersonR GET PUT\r\n/api/admin/addPerson AdminApiAddPersonR POST</code></pre>\r\n<h1 id=\"types-and-parsing\">Types and parsing</h1>\r\n<p>There are two important approaches on making sure that data is valid. Making illegal state unpresentable and parsing instead of validation.</p>\r\n<p>If it’s impossible to create invalid data, you don’t have to validate it. Instead of using <code>Integer</code> and checking that given parameter is 0 or more, you should use <code>Natural</code>. Since <code>Natural</code> can’t have negative values, you don’t have to validate it. Similarly, instead of using a list, you could use <code>NonEmpty</code> to make sure that there’s at least one element present in the collection.</p>\r\n<p>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.</p>\r\n<h1 id=\"person-creation\">Person creation</h1>\r\n<p>Function in charge of generating a new person has signature of <code>generatePersonM :: RandomGen g => StarDate -> PersonOptions -> Rand g Person</code>. Given a current <code>StarDate</code> and <code>PersonOptions</code> describing what kind of person is needed, it will return a computation that can be executed to generate a random person.</p>\r\n<p><code>PersonOptions</code> 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.</p>\r\n<pre><code>data PersonOptions = PersonOptions\r\n { personOptionsAge :: Maybe AgeOptions\r\n } deriving (Show, Read, Eq)</code></pre>\r\n<p><code>AgeOptions</code> has two possibilities. <code>AgeBracket</code> describes case where age should be inside of given range. <code>ExactAge</code> specifies exactly what age should be.</p>\r\n<pre><code>data AgeOptions =\r\n AgeBracket Age Age\r\n | ExactAge Age\r\n deriving (Show, Read, Eq)</code></pre>\r\n<p><code>Age</code> is newtype wrapping <code>Natural</code>, thus <code>Age</code> can never be less than zero.</p>\r\n<pre><code>newtype Age = Age { unAge :: Natural }\r\n deriving (Show, Read, Eq, Num, Ord)</code></pre>\r\n<p>Hand written <code>FromJSON</code> instance takes care of rejecting numbers that aren’t integers and at least zero. One could skip the checks here and parsed <code>Age</code> still couldn’t be negative. Advantage of explicit checks is that we get much nicer error message instead of just annoying runtime exception.</p>\r\n<pre><code>instance FromJSON Age where\r\n parseJSON =\r\n withScientific "age"\r\n (\\x -> case toBoundedInteger x of\r\n Nothing ->\r\n mempty\r\n\r\n Just n ->\r\n if n >= 0 then\r\n return $ Age $ fromIntegral (n :: Int)\r\n\r\n else\r\n mempty)</code></pre>\r\n<p>So, when creating a new person, you can have:</p>\r\n<ul>\r\n<li>no age options at all, computer can pick something</li>\r\n<li>specific age, computer calculates date of birth based on current date</li>\r\n<li>age bracket, computer calculates date of birth based on current date and bracket</li>\r\n<li

But join is not part of the canonical monad definition, which is given by:</p>\r\n<pre><code> return :: Monad m => a -> m a` ; and`\r\n (>>=) :: Monad m => m a -> ( a -> m b ) -> m b\r\n</code></pre>\r\n<p>A good or rather trivial way to think of the relationship between <code>return</code> <code>join</code> and <code>(>>=)</code> is that in essence, since each monad is a functor, then what <code>(>>=)</code> does is that it maps the second argument over the first argument, and then uses <code>join</code> to merge the two applications of the monad constructor, i.e.:</p>\r\n<pre><code> (x >>= f) = join $ fmap f x\r\n</code></pre>\r\n<p>However, join needs to be constructed from <code>return</code> and <code>(>>=)</code>. The naive solution is that we want to <code>trick</code> <code>(>>=)</code> to let us apply a function that does not pile up yet another <code>m</code> onto our initial type <code>m (m a)</code> and surprisingly, this will actually work if we let</p>\r\n<pre><code> join x = (x >>= id)\r\n</code></pre>\r\n<p>Initially this is surprising since <code>id</code> has the signature <code>(c -> c)</code> instead of the necessary <code>a -> m b</code>! However, when <code>c</code> is not an atomic type, but rather of the form <code>m d</code> for some (maybe atomic) type <code>d</code>, then we actually have the signature <code>m d -> m d</code>, and if we bind type <code>a</code> to <code>m d</code> and type <code>b</code> to <code>d</code>, we obtain <code>id</code> with actual type signatuare <code>a -> m b</code>, and it can indeed be used as the second argument of <code>(>>=)</code>, and everything actually makes sense.</p>\r\n<p>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 <code>>>=</code>:</p>\r\n<pre><code> join = (>>= id)\r\n</code></pre>\r\n<p>This is all fine and well for the type number, and it <em>does</em> work, but it\'s also important to understand how it works, so let\'s see it in a simple example, using the <code>Maybe</code> monad. So let\'s start by refreshing the implementation of the monad instance:</p>\r\n<pre><code>instance Monad Maybe where\r\n\r\n (>>=) :: Maybe a -> (a -> Maybe b) -> Maybe b\r\n (>>=) Nothing _ = Nothing\r\n (>>=) (Just x) f = f x\r\n\r\n return :: a -> Maybe a\r\n return = Just\r\n</code></pre>\r\n<p>So let\'s now go through the successive bindings when performing <code>(>>=id)</code>:</p>\r\n<pre><code> Just x = Just (Just 2) => x = Just 2\r\n Just x >>= id = id x = x\r\n x = Just 2\r\n</code></pre>\r\n<p>This example is pretty much verbatim the same thing for the <code>Either</code> 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 <code>List</code> monad:</p>\r\n<p>instance Monad List where</p>\r\n<pre><code> (>>=) :: [a] -> (a -> [b]) -> [b]\r\n (>>=) [] _ = []\r\n (>>=) (x:xs) f = f x ++ (xs >>= f)\r\n\r\n return :: a -> [a]\r\n return = (:[])\r\n</code></pre>\r\n<p>Following the bindings again we have</p>\r\n<pre><code> [[2,3],[4]] = (x:xs) => x = [2,3] ; xs = [[4]]\r\n (x:xs)

If so, you’ve used <a href=\"https://www.gnu.org/software/automake/faq/autotools-faq.html\" target=\"_blank\">GNU Autotools</a>. 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.</p>\r\n\r\n<p>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.</p>\r\n\r\n<h2 id=\"autotools-at-work\">Autotools at work</h2>\r\n\r\n<p>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 <a href=\"https://opensource.com/article/18/1/how-install-apps-linux\">installing apps on Linux</a>.</p>\r\n\r\n<p>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.</p>\r\n\r\n<p>Autotools works in stages:</p>\r\n\r\n<ol>\r\n<li>First, during the <strong>./configure</strong> 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.</li>\r\n<li>Next, during the <strong>make</strong> step, Autotools builds the application, usually by converting human-readable source code into machine language.</li>\r\n<li>Finally, during the <strong>make install</strong> step, Autotools copies the files it built to the appropriate locations (as detected during the configure stage) on your computer.</li>\r\n</ol><p>This process seems simple, and it is, as long as you use Autotools.</p>\r\n\r\n<h2 id=\"the-autotools-advantage\">The Autotools advantage</h2>\r\n\r\n<p>GNU Autotools is a big and important piece of software that most of us take for granted. Along with <a href=\"https://en.wikipedia.org/wiki/GNU_Compiler_Collection\" target=\"_blank\">GCC (the GNU Compiler Collection)</a>, Autotools is the scaffolding that allows Free Software to be constructed and installed to a running system. If you’re running a <a href=\"https://en.wikipedia.org/wiki/POSIX\" target=\"_blank\">POSIX</a> 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.</p>\r\n\r\n<p>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.</p>\r\n\r\n<h3 id=\"portability\">Portability</h3>\r\n\r\n<p>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 platfor

(3052,'2020-04-14','Locating computers on a network',1322,'Ken explains some different ways to locate computers on the network','<h1>Locating computers on a network</h1>\r\n\r\n<p>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.</p>\r\n\r\n<h2 id=\"locating-using-your-router\">Locating using your router.</h2>\r\n\r\n<p>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/<a href=\"https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol\">DHCP</a> server on your network then this should be a matter of logging in and getting the address from the menu area probably called <code>Network</code> or <code>LAN</code> 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 <em>Raspberry Pi Foundation</em>.</p>\r\n\r\n<p>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, <a href=\"https://www.youtube.com/watch?v=5u52wbqBgEY\">How does Ethernet work? (animated)</a> by <a href=\"https://www.youtube.com/channel/UCXkx8hX8Xo4lb7T0_-yZzVg\">Janos Pasztor</a></p>\r\n\r\n<h2 id=\"arp\">ARP</h2>\r\n\r\n<p>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 <a href=\"https://en.wikipedia.org/wiki/Address_Resolution_Protocol\">ARP</a> protocol. This provides a mapping between a device\'s permanent <a href=\"https://en.wikipedia.org/wiki/MAC_address\">MAC address</a> and their, often temporarily, assigned <a href=\"https://en.wikipedia.org/wiki/IP_address\">IP address</a>.</p>\r\n\r\n<p>When your computer <code>192.168.1.1</code> wants to talk to another device it will need to know the Ethernet <a href=\"https://en.wikipedia.org/wiki/MAC_address\">MAC address</a> of the other device. Let\'s assume it wants to connect to the local printer <code>192.168.1.2</code> 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.</p>\r\n\r\n<p>Linux has a command called <code>arp</code> which will show you a list of the IP addresses mapped to the MAC/HWaddress address.</p>\r\n<pre><code># arp -n\r\nAddress HWtype HWaddress Flags Mask Iface\r\n192.168.1.254 ether ff:ee:dd:cc:bb:aa C eno1\r\n192.168.1.2 ether 00:11:22:33:44:55 C eno1\r\n192.168.1.1 ether 00:aa:bb:cc:dd:ee C eno1\r\n</code></pre>\r\n\r\n<p>From a <a href=\"https://en.wikipedia.org/wiki/Internet_Protocol\">Internet Protocol (IP)</a> point of view all your devices in your house are probably in the same <a href=\"https://en.wikipedia.org/wiki/Subnetwork\">Subnet(work)</a>. But what if you need to communicate outside your network? For example to ping a well known server <code>8.8.8.8</code> to check if you have an Internet Connection. The IP settings also include a <a href=\"https://en.wikipedia.org/wiki/Default_gateway\">Default gateway</a> to send all traffic not intended for the local network.</p>\r\n\r\n<h2 id=\"finding-the-default-gateway\">Finding the Default gateway</h2>\r\n\r\n<p>Your c

It reported that the <code>pifacecad</code> module wasn’t present. I tried to install the module using the standard <code>apt-get</code> 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 <code>python-lirc</code> library. I’m guessing the upgrade broke something.</p>\r\n<p>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 <code>raspi-config</code> util and rebooted the pi.</p>\r\n<p>I then tested the installation by running the <code>sys-info.py</code> example that is mentioned in the installation documentation that comes with the pifacecad board.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.

How to do this?</p>\r\n<p>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!</p>\r\n<p>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.</p>\r\n<h3 id=\"the-problem\">The problem</h3>\r\n<p>The thing I was having difficulties with was an <code>alias</code> definition of a useful pipeline:</p>\r\n<pre><code>nmap -sn 192.168.0.0/24 | awk '/^Nmap scan report/{print ""; print; next}{print}'</code></pre>\r\n<p>This uses <code>nmap</code> (see Ken’s show <a href=\"https://hackerpublicradio.org/eps.php?id=3052\" title=\"hpr3052 :: Locating computers on a network\">3052</a> for a discussion of its use) piped into an <code>awk</code> one-liner that formats the information returned by <code>nmap</code>.</p>\r\n<p>The <code>alias</code> command can be used to store such a command or command sequence as a single simple command. It’s usually added to the <code>~/.bashrc</code> file so it gets added to every Bash shell you start up (note <em>Bash Tips #22</em>, currently being written, will cover these startup files).</p>\r\n<p>An <code>alias</code> definition looks something like this:</p>\r\n<pre><code>alias la='ls -Al'</code></pre>\r\n<p>The alias itself <code>\'la\'</code> is defined as the command <code>ls -Al</code>.</p>\r\n<p>So how to make my <code>nmap</code> sequence into an alias given that the commands contain both single and double quotes?</p>\r\n<h3 id=\"quoted-strings-in-bash\">Quoted strings in Bash</h3>\r\n<p>Bash is (to my mind) a bit weird with quoted strings.</p>\r\n<p>There are two sorts of quotes in Bash (leaving aside the <em>backquote</em> or <em>backtick</em> – <code>`</code>):</p>\r\n<ul>\r\n<li><p>Single quotes, also called <em>hard</em> quotes (<code>\'</code>). The literal value of characters between the quotes is preserved. Single quotes are not allowed, even if preceded by backslash escape characters.</p></li>\r\n<li><p>Double quotes, also called <em>soft</em> quotes (<code>\"</code>). Certain characters within the quotes have special meanings, such as <code>\'$\'</code> and <code>\'\\'</code>. Double quotes are allowed in the string when preceded by a backslash.</p></li>\r\n</ul>\r\n<p>There’s a more comprehensive treatment of these quoting types (and others) in the <a href=\"https://www.gnu.org/software/bash/manual/html_node/Quoting.html\" title=\"Bash Reference Manual: 3.1.2 Quoting\">Bash Reference Manual</a>.</p>\r\n<h3 id=\"changing-quotes-and-concatenating-strings\">Changing quotes and concatenating strings</h3>\r\n<p>To make a variable containing a string with embedded quotes you can do this:</p>\r\n<pre><code>$ x='string1'"'"'string2'\r\n$ echo $x\r\nstring1'string2</code></pre>\r\n<p>What we did here was close <code>\'string1\'</code>, start a new string enclosed in double quotes <code>\"\'\"</code>, then append a second string <code>\'string2\'</code>. Bash treats the three strings as one, but they have to be contiguous. There must be no intervening spaces<a href=\"#fn1\" class=\"footnote-ref\" id=\"fnref1\"><sup>1</sup></a>.</p>\r\n<p>This solution is rather ugly. You could also use Bash string concatenation to do this, though it’s more long-winded:</p>\r\n<pre><code>$ x='string1'\r\n$ x+="'"\r\n$ x+='string2'\r\n$ echo $x\r\nstring1'string2</code></pre>\r\n<p>The same principles hold for double quotes of course:</p>\r\n<pre><code>$ x="string1"'"'"string2"\r\n$ echo $x\r\nstring1"string2</code>

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, <a rel=\"noreferrer noopener\" href=\"https://www.palain.com/health-topics/scientific-and-medical-reports/\" target=\"_blank\">Scientific and Medical Reports</a>, which is highly relevant right now. While I could not have predicted this pandemic when I wrote it, it contains basic principles that are <em>always</em> relevant. </p>\r\n\r\n\r\n\r\n<p>The nature of the press is that it is like the carnivorous plant in the movie <em>Little Shop of Horrors</em>, 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:</p>\r\n\r\n\r\n\r\n<ul><li>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.</li><li>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.</li><li>If you really want to know w

The document is marked with an <code>fh:complete</code> element.</li>\r\n <li>Section 3 defines the <em>paged feed</em>: It is a series of documents connected with Atom <code>link</code> elements with <code>rel</code> set to the <em>link relations</em> <code>first</code>, <code>last</code>, <code>previous</code> or <code>next</code>.</li>\r\n <li>Section 4 defines the <em>archived feed</em>: It has a <em>subscription document</em> that may change at any time, and a series of <em>archive documents</em> that are expected to have stable contents and URIs. The link relations defined are <code>current</code>, <code>prev-archive</code> and <code>next-archive</code>. The semantics are clearer: <code>prev-archive</code> 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.

(3088,'2020-06-03','Matchbox Restoration Part 2',307,'Second episode discussing restoring Matchbox diecast models Tony talks tools and materials needed ','<h3 id=\"matchbox-hpr-episode-2-equipment\">Matchbox HPR Episode 2 – Equipment</h3>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Wire brushes for cleaning the remains of any paint that didn’t get removed by the paint stripper.</p>\r\n<p>Hemostat Clamp Tweezers or crocodile clips on a rod, for use to hold the model during spray painting</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Small table vice for holding the model. A set of helping hands for the same during painting, particularly when painting fine details.</p>\r\n<p>So that’s the tools, now the consumables:</p>\r\n<ul>\r\n<li>Gloves – Rubber washing up gloves to protect from some of the chemicals used to strip paint.</li>\r\n<li>Latex gloves for using when spray painting as you have more control while wearing these rather than the looser fitting rubber washing up gloves.</li>\r\n<li>Work gloves to use when drilling or using other tools.</li>\r\n<li>Paint face mask to prevent inhaling fumes.</li>\r\n<li>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.</li>\r\n<li>Model filler for repairing dents in the casting</li>\r\n<li>Wir

I wanted to make the<br />movies and TV Shows easily accessible on the TV without using a DVD or Blu ray<br />player.</p>\r\n<p>It would give my wife and I a chance to sit and watch a show without much<br />fuss. The latest show we are on is Sue Thomas F.B. Eye.<br />The main character, Sue has been deaf from about the age of 4 years.<br />She is adept at reading lips and learned to speak despite being deaf.</p>\r\n<p><a title=\"Sue Thomas F.B.

The fan<br />still worked, so I wired it to the Pi on the 5v line. It runs at half the<br />speed it was designed for, but that makes it run almost silent. With the<br />heatsinks added, stays about 35C when idle and 50C when encoding video.</p>\r\n<h3>Pi Networking.</h3>\r\n<p>I have 2 Pi\'s connected via ethernet. One is on 192.168.2.5 with a gateway of<br />192.168.2.6, with the other on 192.168.2.6 with a gateway of 192.168.2.5.<br />Essentially just a crossover network.

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.</p>\r\n<p>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.</p>\r\n<p>Picture 000:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_000.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_000_thumbnail.jpg\" alt=\"Picture 000\" /></a></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Picture 001:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_001.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_001_thumbnail.jpg\" alt=\"Picture 001\" /></a></p>\r\n<p>I drilled out this post. 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.</p>\r\n<p>Picture 003:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_003.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_003_thumbnail.jpg\" alt=\"Picture 003\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 005:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_005.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_005_thumbnail.jpg\" alt=\"Picture 005\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 006:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_006.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_006_thumbnail.jpg\" alt=\"Picture 006\" /></a></p>\r\n<p>Picture 006x:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_006x.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_006x_thumbnail.jpg\" alt=\"Picture 006x\" /></a></p>\r\n<p>This process was repeated with the other 3 castings and the result is shown in the next picture</p>\r\n<p>Picture 008:<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3098/img_008.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3098/img_008_thumbnail.jpg\" alt=\"Picture 008\" /></a></p>\r\n<p>As you can see the casting on the upper left of the ima

(3101,'2020-06-22','Metrics',1553,'A layman\'s explanation of the mathematical concept of metric.','<p>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.</p>\r\n<h3 id=\"what-is-a-metric\">What is a metric?</h3>\r\n<p>A type of ruler that is used in mathematics.</p>\r\n<h3 id=\"why-not-just-use-a-ruler\">Why not just use a ruler?</h3>\r\n<p>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.</p>\r\n<h3 id=\"whats-the-simplest-example-of-a-metric\">What\'s the simplest example of a metric?</h3>\r\n<p>In 1D, distance s equals change in x coordinate.</p>\r\n<h3 id=\"ok-can-i-have-a-more-interesting-example-please\">OK, can I have a more interesting example please?</h3>\r\n<p>On a flat 2D surface, distance squared is the change in x squared plus change in y squared.</p>\r\n<h3 id=\"isnt-that-pythagoras\">Isn\'t that pythagoras?</h3>\r\n<p>Yes, it is, but using the word distance and two co-ordinates.</p>\r\n<h3 id=\"what-other-co-ordinates-can-we-use-for-a-flat-2d-surface\">What other co-ordinates can we use for a flat 2D surface?</h3>\r\n<p>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.</p>\r\n<h3 id=\"does-pythagoras-still-work-in-polar-coords\">Does Pythagoras still work in polar coords?</h3>\r\n<p>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 <em>change</em> in distance squared equals the <em>change</em> in radius squared plus radius squared times the <em>change</em> in φ squared.</p>\r\n<h3 id=\"why-do-we-have-to-talk-about-changes-in-s-r-and-φ\">Why do we have to talk about changes in s, r and φ?</h3>\r\n<p>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.</p>\r\n<h3 id=\"can-we-use-cartesian-or-polar-co-ordinates-on-the-surface-of-the-earth\">Can we use Cartesian or polar co-ordinates on the surface of the Earth?</h3>\r\n<p>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.</p>\r\n<h3 id=\"why-not\">Why not?</h3>\r\n<p>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.</p>\r\n<h3 id=\"i-want-to-know-more-or-my-mind-is-not-fully-blown\">I want to know more OR my mind is not fully blown.</h3>\r\n<p>I will probably do more shows on this.</p>\r\n<h3 id=\"can-i-have-some-links\">Can I have some links?</h3>\r\n<p>Sure:</p>\r\n<ul>\r\n<li><a href=\"https://en.wikipedia.org/wiki/Alcubierre_drive\">Alcubierre drive</a></li>\r\n<li><a href=\"https://en.wikipedia.org/wiki/Darts\">Dart board</a></li>\r\n<li><a href=\"https://en.wikipedia.org/wiki/Polar_coordinate_system\">Polar coordinates</a></li>\r\n<li><a href=\"https://en.wikiped

(3109,'2020-07-02','Matchbox Restoration Part 4',277,'In this the 4th in the series Tony discusses paint removal on the castings of the MK10 Jaguars','<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Picture 000<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3109/img_000.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3109/img_000_thumbnail.jpg\" alt=\"Picture 000\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 001<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3109/img_001.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3109/img_001_thumbnail.jpg\" alt=\"Picture 001\" /></a></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Picture 002<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3109/img_002.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3109/img_002_thumbnail.jpg\" alt=\"Picture 002\" /></a></p>\r\n<p>Picture 003<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3109/img_003.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3109/img_003_thumbnail.jpg\" alt=\"Picture 003\" /></a></p>\r\n<p>Picture 004<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3

(3124,'2020-07-23','Matchbox Restoration Part 5',310,'In this the 5th in the series Tony discusses the painting process on the castings of the MK10 Jaguar','<h2 id=\"hpr-matchbox-show-episode-5\">HPR Matchbox show Episode 5</h2>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Image 001<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3124/img_000.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3124/img_000_thumbnail.jpg\" alt=\"Image 001\" /></a></p>\r\n<p>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.</p>\r\n<p>Image 002<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3124/img_001.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3124/img_001_thumbnail.jpg\" alt=\"Image 002\" /></a></p>\r\n<p>Image 003<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3124/img_002.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3124/img_002_thumbnail.jpg\" alt=\"Image 003\" /></a></p>\r\n<p>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.</p>\r\n<p>Image 004<br />\r\n<a href=\"https://

The largest of these circles is at latitude 0° and is called the <strong>equator</strong>. Its circumference is equal to that of the Earth and so it is an example of a <strong>great circle</strong>.</p>\r\n<p>On the right we see lines of constant longitude. These run from pole to pole and are perpendicular to the equator. Each of these lie on a great circle (in fact they are half a great circle each).</p>\r\n<p>Great circles on the surface of a sphere are analogous to straight lines on a flat 2D surface. 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 <strong>geodesic</strong>. In physics, particles that are not subject to any forces will follow geodesics.</p>\r\n<p>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.</p>\r\n<p>Here are the equations discussed in this show and the previous one:</p>\r\n<img alt=\"Sphere with latitude and longitude\" src=\"https://hackerpublicradio.org/eps/hpr3126/metric_equations.png\">\r\n\r\n',268,0,0,'CC-BY-SA','maths,relativity,physics,earth',0,0,1),

(3132,'2020-08-04','Keeping track of where I am',1362,'How I keep track of where I am','<p>This episode covers how I keep track of what I\'m listening to</p>\r\n<p>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.</p>\r\n<p>These ideas slowly evolved over time and I think some of them may now be redundant. I think I need to do some tidying.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Command used to create index</p>\r\n<pre><code>id3v2 -l *.mp3 | grep 'TIT2' | cut -c44- >> readme.txt\r\nid3v2 -l *.mp3 | grep 'TIT2' | cut -c44- | egrep 'HPR[01][9][7-9]' >> readme.txt\r\nid3v2 -l *.mp3 | grep 'TIT2' | cut -c44- | egrep 'HPR[1-9]' |less >> readme.txt\r\n========================================================\r\n========================================================</code></pre>\r\n<p>Example output</p>\r\n<pre><code>epr0006.mp3 - dosman complete\r\nhpr0010.mp3 - linux boot process, part 1 complete\r\nhpr0012.mp3 - zen virtulization complete\r\nhpr0018.mp3 - book review complete</code></pre>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>The script sometimes worked but it was a bit flaky and didn\'t always work.</p>\r\n<p>My final solution is in multiple parts</p>\r\n<p>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.</p>\r\n<p>First script</p>\r\n<pre><code>~/scripts/podcasts\r\n\r\nquick lash up of script created 29/12/12 (DD/MM/YY)\r\nCreated to keep track of last position of listened podcast\r\n\r\nScript displays last 4 lines of logfile "podcasts.txt"\r\nThe four lines consist of a Dashed line separator, the last recorded Track\r\nTitle, last recorded Filename and the last recorded track position.\r\nThe script then pauses and displays a message saying\r\npress any key to continue.\r\nRuns mocp\r\nWhen the frontend of mocp exits\r\nThe script gets the current track filename\r\nIf the result is empty ie no filename then\r\n exit with error saying (moc was not playing anything)\r\nif not empty\r\n append a dashed line separator, the current track title, the current\r\n filename, the current track position to logfile it then

(3136,'2020-08-10','Matchbox Restoration Part 6',286,'Matchbox Cars, Diecast Models, Restoration, Reassembly of the model','<p>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.</p>\r\n<p>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.</p>\r\n<p>Picture 001<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_001.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_001_thumbnail.jpg\" alt=\"Picture 001\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 002<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_002.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_002_thumbnail.jpg\" alt=\"Picture 002\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 003<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_003.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_003_thumbnail.jpg\" alt=\"Picture 003\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 004<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_004.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_004_thumbnail.jpg\" alt=\"Picture 004\" /></a></p>\r\n<p>Followed by the plastic interior, the eagle eyed among you will notice a colour change to the body work as I forgot to take a picture of this stage on the gold model. 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.</p>\r\n<p>Picture 005<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_005.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_005_thumbnail.jpg\" alt=\"Picture 005\" /></a></p>\r\n<p>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.</p>\r\n<p>Picture 006<br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3136/img_006.jpg\"><img src=\"https://hackerpublicradio.org/eps/hpr3136/img_006_thumbnail.jpg\" alt=\"Picture 006\" /></a></p>\r\n<p>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 pre

(3145,'2020-08-21','A light bulb moment, part 1',649,'Finding the working voltage of a bulb','<p>This show came about because of an email from Dave Morriss on the 4th March 2020</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>I can demonstrate this by measuring the resistance of two light bulbs I have lying around the house.</p>\r\n<p>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</p>\r\n<p>The other bulb was a Halogen E14 screw in bulb rated at 28W and its operating voltage like the previous bulb was 240V.

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.</p>\r\n<p>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.</p>\r\n<p>Another person suggested trying to estimate the length of the filament and using this to determine the working voltage.</p>\r\n<p>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.</p>\r\n<p>It isn\'t so simple if bulb requires a higher voltage.</p>\r\n<p>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.</p>\r\n<p>Feel free to write a comment if any of you out there have any other idea on finding the working voltage of a bulb this way it can be shared with the rest of us during the Community Ne

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. <br />\r\nFrom <a href=\"https://musopen.org/music/14910-the-four-seasons-op-8/\">Vivaldi The Four Seasons, Op. 8</a>\r\n</p>\r\n\r\n<p>\r\n<a href=\"https://musopen.org/music/performer/the-modena-chamber-orchestra/\">The Modena Chamber Orchestra Music</a>\r\n</p>',383,22,0,'CC-BY-SA','Vivaldi, four seasons, creative commons',0,0,1),

(3158,'2020-09-09','Fingerprint access control? LOL... ',1201,'A story about pentesting physical security','<p>Hello everyone, my name is Cedric and I\'m here again with another story on pentesting and security, straight from the trenches.</p>\r\n<p>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.</p>\r\n<p>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 ;-)</p>\r\n<p>Our approach was basically the same as that of a professional burglar: we\'d start with a week of preparation and scoping the place.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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

It took a great deal of effort to convince people to use it because gas lighting was so well established and worked well.</p>\r\n<p>Many houses in Britain didn\'t install electric lighting until the 1930s</p>\r\n<p>Finally electricity won as it could be used for so many other things.</p>\r\n<p><u><strong>The tungsten filament bulb</strong></u></p>\r\n<p>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.</p>\r\n<p><u><strong>The tungsten halogen bulb</strong></u></p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p><u><strong>Fluorescent neon lights</strong></u></p>\r\n<p>Fluorescent neon lights were invented in 1905 by a French man called George Claude. These were used for advertising mainly in America.</p>\r\n<p><u><strong>Fluorescent strip light</strong></u></p>\r\n<p>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.</p>\r\n<p>Fluorescent tubes are four times as efficient as normal incandescent light bulbs and run cool.</p>\r\n<p>The first energy efficient light bulbs were just fluorescent lights folded into a compact bulb shape.</p>\r\n<p><u><strong>Sodium lights</strong></u></p>\r\n<p>Sodium lights used mainly in street lighting are twice as efficient again as fluorescent bulbs they give off a rather horrible orange colour.</p>\r\n<p>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 <a href=\"https://en.wikipedia.org/wiki/Sodium-vapor_lamp\" class=\"uri\">https://en.wikipedia.org/wiki/Sodium-vapor_lamp</a></p>\r\n<p>The next big development was LED lighting which I\'ll cover in my next episode.</p>\r\n',201,0,0,'CC-BY-SA','Hardware, electrical',0,0,1),

(3192,'2020-10-27','A light bulb moment, part 3',777,'The LED revolution','<p><strong><u>LED History</u></strong></p>\r\n<p>The history of the LED revolution is both long and complex but I\'ll do my best to cover it. Please forgive me if I mispronounce some of the materials and processes I\'m not a lighting expert as I stated right back at the beginning of this series.</p>\r\n<p>The following excerpts are from Wikipedia; the link will be in the show notes, <a href=\"https://en.wikipedia.org/wiki/Light-emitting_diode\">https://en.wikipedia.org/wiki/Light-emitting_diode</a></p>\r\n<p>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.</p>\r\n<p>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]</p>\r\n<p>In 1968 Monsanto was the first organization to mass-produce visible LEDs, these were red LEDs suitable for indicators.[32]</p>\r\n<p>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]</p>\r\n<p>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.</p>\r\n<p>The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines</p>\r\n<p>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]</p>\r\n<p>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.</p>\r\n<p>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].</p>\r\n<p>In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a \"transparent contact\" LED using indium tin oxide (ITO) on (AlGaInP/GaAs).</p>\r\n<p>In 2001[62] and 2002,[63] processes for growing gallium nitride (GaN) LEDs on silicon were successfully demonstrated.</p>\r\n<p>In January 2012, Osram demonstrated high-power InGaN LEDs grown on silicon substrates commercially,[64] and GaN-on-silicon LEDs are in producti

This is often called a "key and value pair", but in YAML it's just called a mapping.\r\n</p>\r\n\r\n<h2>Combining data blocks</h2>\r\n\r\n<p>\r\nYou can embed these data types into one another.

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.</p>\r\n<p>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.</p>\r\n<p>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:</p>\r\n<p><em>Pictor all sky images of hydrogen in our galaxy</em><br />\r\n<a href=\"https://hackerpublicradio.org/eps/hpr3243/img_001.png\"><img src=\"https://hackerpublicradio.org/eps/hpr3243/img_001_thumbnail.png\" alt=\"Pictor all sky images of hydrogen in our galaxy\" /></a></p>\r\n<p>Here are the results of the observation I performed during the show.

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.\r\n</p>\r\n<ul>\r\n<li><a href=\"https://www.linkedin.com/in/anco-scholte-ter-horst-5309171/\">https://www.linkedin.com/in/anco-scholte-ter-horst-5309171/</a></li>\r\n<li><a href=\"https://opennebula.io/\">https://opennebula.io/</a></li>\r\n<li><a href=\"https://internet.nl/\">https://internet.nl/</a></li>\r\n<li><a href=\"https://nl.wikipedia.org/wiki/Freedom_Internet\">https://nl.wikipedia.org/wiki/Freedom_Internet</a></li>\r\n<li><a href=\"https://en.wikipedia.org/wiki/XS4ALL\">https://en.wikipedia.org/wiki/XS4ALL</a></li>\r\n<li><a href=\"https://www.bit.nl/\">https://www.bit.nl/</a></li>\r\n</ul>\r\n',30,78,0,'CC-BY-SA','Freedom.nl,xs4all,ISP,crowdfunding',0,0,1),

(3252,'2021-01-19','Simple JSON querying tool (also YAML, and to a lesser extent XML)',1137,'crvs talks about jq, yq and xq','<h1 id=\"json\">JSON</h1>\r\n<p>Json is a cool little data serialization language, that allows you to easily and clearly demarcate blocks of data by nesting data structures such as lists (enclosed by square brackets) and key-value pairs or \"dictionaries\" (enclosed by curly braces). So that in the end you get something that looks like this</p>\r\n<pre><code>{\r\n"first list" : [ "element1", "element2", {"element3" : "is another k-v pair", "but contains" : ["a" , "list", "of", "words"]}] ,\r\n"this value is a string" : "1" ,\r\n"and this is a number" : 23 ,\r\n"and floating point" : 1.413\r\n}</code></pre>\r\n<p>Aside from:</p>\r\n<ul>\r\n<li>Lists are enclosed in [] and each element is separated by ,</li>\r\n<li>Key-value pair lists are enclosed in {} and have the key and value separated by : and each pair is separated by ,</li>\r\n<li>Keys have to strings quoted with double quotes</li>\r\n<li>Numbers may be left unquoted (but just in value fields)</li>\r\n</ul>\r\n<p>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. <a href=\"https://stedolan.github.io/jq/\">My favourite JSON parser is jq(1)</a>.</p>\r\n<p>A canonical representation of the JSON example above can easily be obtained with jq by simply calling <code>jq \'\' file.json</code> (or piping the file through stdin, or even putting the contents properly quoted as the second argument).</p>\r\n<pre><code>{\r\n "first list": [\r\n "element1",\r\n "element2",\r\n {\r\n "element3": "is another k-v pair",\r\n "but contains": [\r\n "a",\r\n "list",\r\n "of",\r\n "words"\r\n ]\r\n }\r\n ],\r\n "this value is a string": "1",\r\n "and this is a number": 23,\r\n "and floating point": 1.413\r\n}</code></pre>\r\n<p>You can also use jq in a shell script to obtain, for example the second element of the first list:</p>\r\n<pre><code>$ jq '."first list"[1]' example.json\r\n"element2"</code></pre>\r\n<p>So to get the value associated to a key you use the notation <code>.key</code> and to get the k-th element you use the notation <code>[k-1]</code>. To remove the quotes on the string you can use the <code>-r</code> flag which stands for raw output.</p>\r\n<p><code>jq(1)</code> also gives you a few more functionalities that can be useful like getting the number of elements in a list with the length function.</p>\r\n<pre><code>$ jq 'length' example.json\r\n3\r\n$ jq '."first list"[2]."but contains" | length'\r\n4</code></pre>\r\n<p>Another useful feature is getting the list of keys from a key-value pair list which can be done with the function <code>keys</code></p>\r\n<pre><code>$ jq '."first list"[2] | keys[]' example.json\r\n"but contains",\r\n"element3"</code></pre>\r\n<p>The query language is much much more flexible than this, but for most cases this should be enough for simple configuration querying.</p>\r\n<h1 id=\"yaml-and-xml\">YAML and XML??</h1>\r\n<p><a href=\"https://pypi.org/project/yq/\">The yq project</a> 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.</p>\r\n<p>So for example looking at the previous file through <code>yq</code> gives:</p>\r\n<pre><code>$ yq -y '' example.json\r\nfirst list:\r\n - element1\r\n - element2\r\n - element3: is another k-v pair\r\n but contains:\r\n - a\r\n - list\r\n - of\r\n - words\r\nthis value is a string: '1&

(3264,'2021-02-04','Intro to Nagios',1200,'Introduce some nagios basics and walk through setting up nagios on Ubuntu','<h1 id=\"nagios-basics\">Nagios Basics</h1>\r\n<h2 id=\"introduction\">Introduction</h2>\r\n<p>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</p>\r\n<p>Nagios is a network monitoring tool. You define some things for nagios to check, and nagios will alert you if those checks fail.</p>\r\n<p>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</p>\r\n<ul>\r\n<li>enabling/disabling notifications</li>\r\n<li>Scheduling Downtime</li>\r\n<li>Forcing immediate checks</li>\r\n</ul>\r\n<p>Nagios is primarily configured with text files. You have to edit the nagios config files for things like</p>\r\n<ul>\r\n<li>adding servers</li>\r\n<li>customizing commands</li>\r\n</ul>\r\n<h2 id=\"nagios-core-vs-nagiosxi\">Nagios core vs NagiosXI</h2>\r\n<p>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.</p>\r\n<p>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</p>\r\n<p>The <code>community</code> version of nagios is normally referred to as <code>nagios core</code> This episode will focus on the nagios core</p>\r\n<h2 id=\"nagios-documentation\">Nagios Documentation</h2>\r\n<p>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.</p>\r\n<p>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</p>\r\n<p>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.</p>\r\n<p>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</p>\r\n<p>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</p>\r\n<h2 id=\"hosts-and-services\">Hosts and Services</h2>\r\n<p>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.</p>\r\n<p>From the Nagios documentation</p>\r\n<blockquote>\r\n<p>A host definition is used to define a physical server, workstation, device, etc. that resides on your network.</p>\r\n</blockquote>\r\n<p>Also from the nagios documentation</p>\r\n<blockquote>\r\n<p>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</p>\r\n</blockquote>\r\n<p>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</p>\r\n<h2 id=\"installation-and-setup\">Installation and setup</h2>\r\n<p>Install the packages</p>\r\n<pre><code>apt install nagios4</code></pre>\r\n<p>On

Therefore you should check the available and used disk space usage first:</p>\r\n<pre><code>$ df -h</code></pre>\r\n<p>Step 2: Check package status</p>\r\n<p>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:</p>\r\n<pre><code>$ sudo dpkg --audit\r\n$ sudo dpkg --get-selections | grep hold</code></pre>\r\n<p>Step 3: Update system</p>\r\n<p>Before upgrading, the Raspbian should be completely updated:</p>\r\n<pre><code>$ sudo apt-get update\r\n$ sudo apt-get upgrade\r\n$ sudo apt-get dist-upgrade</code></pre>\r\n<p>Step 4: Modify Release</p>\r\n<p>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:</p>\r\n<pre><code>$ sudo sed -i /deb/s/jessie/stretch/g /etc/apt/sources.list\r\n$ sudo sed -i /deb/s/jessie/stretch/g /etc/apt/sources.list.d/*.list</code></pre>\r\n<p>Step 5: Updating package lists</p>\r\n<p>The new package lists must then be updated and imported:</p>\r\n<pre><code>$ sudo apt-get update</code></pre>\r\n<p>Step 6: Update to \"Stretch\"</p>\r\n<p>Now we are ready to start the upgrade:</p>\r\n<pre><code>$ sudo apt-get upgrade\r\n$ sudo apt-get dist-upgrade</code></pre>\r\n<p>Step 7: Clean up installation</p>\r\n<p>Old, unnecessary packages are removed after the system update with the following commands:</p>\r\n<pre><code>$ sudo apt-get autoremove\r\n$ sudo apt-get autoclean</code></pre>\r\n<h2 id=\"what-was-reported-during-upgrade\">What was reported during upgrade</h2>\r\n<h3 id=\"repo-for-get_iplayer-no-longer

(3286,'2021-03-08','Wireguard How To',574,'My findings setting up wireguard at home and in my office at work.','<h2 id=\"wireguard-how-to\">Wireguard How To</h2>\r\n<p>Firstly, I am not an expert. These are just my findings setting up wireguard at home and in my office at work.</p>\r\n<p>I\'ve used a program called <code>sshuttle</code> 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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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 <a href=\"https://bugs.python.org/issue35415\" class=\"uri\">https://bugs.python.org/issue35415</a>.</p>\r\n<p>Anyway.</p>\r\n<p>I thought it was about time I looked at setting up a proper VPN on my work network.</p>\r\n<p>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.</p>\r\n<p>Then I spent a couple more hours poking around trying to figure out why it wouldn\'t work.</p>\r\n<p>I eventually gave up frustrated.</p>\r\n<p>I\'m not blaming openVPN, I know it works for many many people, but I couldn\'t see what was wrong.</p>\r\n<p>So I did what we all do in a situation like this.</p>\r\n<p>I took to social media, which in my case is my pleroma server and posted a message to the fediverse.</p>\r\n<p><em>\"OpenVPN has fried my brain. Need booze\"</em><br />\r\nThen I had a beer, a nice cold Stiegl goldbrau if I remember right.</p>\r\n<p>A few minutes later a message popped up from theru, it contained one word with a smiley face. Wireguard.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>I\'m using Arch linux on my servers but I see the Linode Debian \'how to\' works in the same way.</p>\r\n<p>So we are going to log into the server and start the setup.</p>\r\n<h3 id=\"st-create-private-and-public-keys\">1st create Private and Public keys</h3>\r\n<p>Create directory for Keys</p>\r\n<pre><code>cd ~\r\nmkdir wireguard\r\ncd wireguard</code></pre>\r\n<p>Create Server Keys</p>\r\n<pre><code>umask 077\r\nwg genkey | tee privatekey | wg

(3296,'2021-03-22','Spam Bot Honey Pot',364,'Implementing a honey pot style spam filter for your HTML forms','<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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\".</p>\r\n<p>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 v

(3305,'2021-04-02','Nagios part 2',1428,'Follow up to hpr3264 - Notifications, SNMP, Remote Checks','<p>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.</p>\r\n<h2 id=\"why-use-nagios\">Why use nagios</h2>\r\n<p>One thing I meant to talk about but forgot in the intro is why you may want to run nagios as a hobbyist.</p>\r\n<ul>\r\n<li>Education, learning a new technology for fun</li>\r\n<li>Network Monitoring is a valuable skill and benefit your career if you work in IT</li>\r\n<li>Early warning for failing hardware</li>\r\n<li>Monitoring self hosted applications</li>\r\n<li>Notification for home security devices IP cameras</li>\r\n</ul>\r\n<p>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.</p>\r\n<h2 id=\"notification-options\">Notification Options</h2>\r\n<h3 id=\"email\">Email</h3>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>There are a few ways to get around this problem. I use the email delivery service <code>Sendgrid</code>. They do all the work of staying off the list of spammers, and most email providers trust mail send via Sendgrid.</p>\r\n<p>I wont go into the instructions for configuring postfix to relay outgoing mail via Sendgrid, but their documentation is easy to follow.</p>\r\n<p>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.</p>\r\n<h3 id=\"push-alerts\">Push alerts</h3>\r\n<p>There are a few options (besides email) for getting alerts on your phone.</p>\r\n<h4 id=\"anag\">aNag</h4>\r\n<p>The easiest way to get alerts is probably the <code>aNag</code> 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.</p>\r\n<p>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.</p>\r\n<p>If you decide to put nagios on a public network, be sure to configure apache to only use HTTPS. <code>certbot</code> makes this really easy.</p>\r\n<h4 id=\"pushover\">Pushover</h4>\r\n<p>Another option is to us a Push Notification service that can send notifications that are triggered by API calls.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Remember from the previous episode, nagios has a <code>conf.d</code> directory and will load any files in that directory. So we will create a new file <code>/etc/nagios4/conf.d/pushover.cfg</code> and restart nagios. The contents of the pushover file will be in the show notes.</p>\r\n<p>To use pushover for specific checks, and the contact to that check. See the example in the show notes. Or if you want to use pushover for everything Modify the definitions for the host and service templates to use pushover as a contact</p>\r\n<p>The script that calls the Pushover API is at <code>https://github.c

Kuhn (from the <a href=\"https://faif.us/\">Free as in Freedom podcast</a>) wrote an article titled \"On Recent Controversial Events\" about the issue. I am submitting that article here under the terms of the Creative Commons Attribution-Share Alike 3.0 United States License. The post contains many links and is available in the shownotes for this show. Some examples are included at the end of the blog post, and listener discretion is advised.</p>\r\n<h1>\r\n<a href=\"https://ebb.org/bkuhn/blog/2019/10/15/fsf-rms.html\">On Recent Controversial Events</a>\r\n</h1>\r\n<p class=\"topAttributionWithDate\">\r\nTuesday 15 October 2019 by Bradley M. Kuhn\r\n</p>\r\n<p>\r\nThe last 33 days have been unprecedentedly difficult for the software freedom community and for me personally. 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 <a href=\"https://www.fsf.org/news/richard-m-stallman-resigns\">his resignation from the Free Software Foundation (FSF)</a>, 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.\r\n</p>\r\n<p>\r\nI have been silent the last month because, until two days ago, I was an at-large member of <a href=\"https://www.fsf.org/about/staff-and-board\">FSF’s Board of Directors</a>, and a <a href=\"https://static.fsf.org/nosvn/fsf-amended-bylaws-current.pdf\">Voting Member</a> 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 <a href=\"https://www.fsf.org/news/richard-m-stallman-resigns\">come</a> <a href=\"https://www.fsf.org/news/fsf-and-gnu\">directly</a> 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.\r\n</p>\r\n<p>\r\nThe situation was further complicated because folks at my employer, Software Freedom Conservancy (where I also serve on the <a href=\"https://sfconservancy.org/about/board/#bkuhn\">Board of Directors</a>) 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

(3317,'2021-04-20','Reading a manifesto: Towards A Cooperative Technology Movement',1015,'If open source misses the point of free software philosophy, what point is free software missing?','<p>Three good decades ago, Richard Stallman founded the free software movement and gave it a name.</p>\r\n<p>Two good decades ago there was a fork and Eric S. Raymond, Bruce Perens and others founded the open\r\nsource software movement, and neglected to tell us who gave it a name.\r\n(it was Christine Peterson<a href=\"#footnote0\">[0]</a>)</p>\r\n<p>Ever since then, the free software side of the two movements has been careful to guard the boundary\r\nbetween the two, see Richard Stallman\'s essay \"<em>Open Source Misses the Point</em>\".<a href=\"#footnote1\">[1]</a></p>\r\n<p>But lately a lot of people have increasingly been feeling that <em>free software</em> misses the point.\r\nIronically a lot of this has been coming from the <em>open source</em> side of things, as the official free\r\nsoftware philosophy has been firmly anchored with Stallman, and he hasn\'t been interested in moving\r\nhis philosophy in more inclusive directions.</p>\r\n<p>For sure, there are a lot of people in free software who have been wanting to go in this direction\r\nas well. I\'ve been thinking of it as a \"free software plus\", as it builds on the free software\r\nphilosophy, but adds aspects of social responsibility. The fact that Stallman was forced to resign\r\nfrom being Free Software Foundation president two years ago was a sign that people inside free\r\nsoftware cared about more than just the code and what freedoms it gives the recipient.</p>\r\n<p>A month ago, if you are listening to this on April the 20th 2021,\r\na manifesto was published called \"<em>Towards A Communal Software Movement</em>\", and I\'ll get to\r\nthat in a minute. I mentioned the names of the drivers of the previous movements, but this author\r\nhas said \"I intentionally left authors\' names out of it\"<a href=\"#footnote2\">[2]</a>, and I think that makes sense. Part of the\r\nproblems with previous movements has been this Great Man of History fallacy, which may have kept\r\nthem focused and on track, but it has also held them back.</p>\r\n<p>The movement is young and has already changed names once as I was writing about it. The manifesto is\r\nnow \"<em>Towards A Cooperative Technology Movement</em>\", and I have updated the shownotes and my commentary\r\nto reflect that.</p>\r\n<p><a href=\"https://misskey.de/notes/8k0igd5tcd\">https://misskey.de/notes/8k0igd5tcd</a></p>\r\n<p>I see the difference between free software and cooperative technology similarly as the difference\r\nbetween open source and free software.</p>\r\n<p>There are certainly people within open source and on the Open Source Initiative board that look\r\nfurther than just the license, and treat open source like just another brand name for free software.</p>\r\n<p>But at its core, the Open Source Definition is all about the licensing and that document is the\r\nshared common ground for all open source. People write code for different reasons and there\'s a\r\nlicense and contribution model that allow them to come together without those differences of purpose\r\ngetting too much in the way.</p>\r\n<p>So if the software and the license is \"what\" we\'re building, the philosophical documents of free\r\nsoftware provide the guidance on \"why\" we are building it: We want to get away from proprietary\r\nsoftware, we want to control our own computing, we want the freedoms to use, learn, modify and\r\nshare, etc. Free software is about our freedoms.</p>\r\n<p>So just like \"free\" is right there in the name, maybe the \"community\" in \"communal software\" or\r\nthe \"cooperative\" in \"cooperative technology\" is\r\nall about the \"who\": Who gets the freedom, who has the influence, who is affected.</p>\r\n<p>And again, lots of people in free software do care about community principles beyond code, care about\r\nsocial responsibility, but the shared baseline is the care for formal, technical and individual

I have been listening to HPR for about a year and after hearing repeated pleas for episodes, I thought I would record some of my own.</p>\r\n<p>I cannot guarantee quality of production nor content, but I hope you find them entertaining.</p>\r\n<p>This episode is simply an introduction with a little bit of information about me</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>Thank you for listening to me prattle on about myself, and have an awesome day.</p>\r\n',394,0,0,'CC-BY-SA','Introduction',0,0,1),

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.\r\n</p>\r\n<p>\r\n<a href=\"https://www.fsf.org/news/rms-addresses-the-free-software-community\">RMS acknowledges that he has made mistakes.</a> 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.\r\n</p>\r\n<p>\r\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.\r\n</p>\r\n<p>\r\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.\r\n</p>\r\n<p>\r\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.

If you wait too long, your connection will likely time out.\r\nView the default landing page of the site you\'ve connected with:\r\n</p>\r\n\r\n<pre><code>\r\nGET / HTTP/1.1\r\nHOST: example.com\r\n</code></pre>\r\n\r\n<p>\r\nIn return, you get a dump of the HTML source of the default page (usually <code>index.html</code>) in your terminal.\r\n</p>\r\n\r\n<p>\r\nYou can also use OpenSSL s_client for email servers using SSL.\r\nBefore you can send credentials, you must encode your email username and passphrase into Base64.

Blanchard\r\n</dd>\r\n</dl>\r\n</blockquote>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n',129,0,0,'CC-BY-SA','Tablet, phone, desktop, windows, pine64, pinetime',0,0,1),

(3367,'2021-06-29','Making books with linux - part 1',3367,'A discussion about assembling books using simple tools commonly found in most linux distros.','<p>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.</p>\r\n<p>Andrew was inspired by a simple and elegant approach to eBook creation by Jon Kulp, possibly from listening to <a href=\"https://hackerpublicradio.org/eps.php?id=1909\">HPR 1909</a> several years ago.</p>\r\n<p>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.</p>\r\n<p>This is not WYSIWYG (what you see is what you get) but using the <em>entr</em> 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).</p>\r\n<p>Dave describes how he achieves something similar to what Andrew has created by using <em>make</em> to co-ordinate the processing. The process of compiling the source text files into a final document does have some similarities with code compilation.</p>\r\n<p>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 <a href=\"https://github.com/mcnalu/howscotlandworks\">How Scotland Works</a>.</p>\r\n<p>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 <a href=\"https://github.com/mcnalu/howscotlandworks/tree/master/scripts/index\">here</a>.</p>\r\n<p>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.</p>\r\n<p>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!</p>\r\n',268,0,0,'CC-BY-SA','linux,books,ebooks,scripts',0,0,1),

(3362,'2021-06-22','Spam Bot Honey Pot: Eating your own dog food',1148,'Reviewing some stats and the accessibility by screen reader of this spam filter method.','<p>\r\nIn this episode, I revisit my spam bot honey pot method of spam detection for \r\nweb forms. The first part of the episode is a response to rtsn comment asking \r\nfor a follow up on how the method worked out. In the second part of the podcast \r\nI use the built-in screen reader of my Pop_OS system to review my test form and \r\nmy work form for audible accessibility and to check that the spam catching URL \r\nfield is not reveled by a screen reader. \r\n</p>\r\n<p>\r\nFor my work site, I pushed the spam catcher to production on 16 February 2021. \r\nThe total submitted form messages from that day until today, 29 May 2021, is 661.\r\nOf the total submitted, the method identified 527 spam messages, and passed \r\nalong 134 messages. Of those 134, 38 messages were uncaught spam--while the \r\nremaining 96 messages were valid inquiries. Overall, it seems to be doing a \r\ngood job. At one point, I thought about closing down the form, but the data \r\ndoes show we are receiving enough valid messages to make it worth keeping around \r\nand this method makes finding the good messages much easier.\r\n</p>\r\n<p>\r\nDuring the second part of the podcast, I find using a screen reader, like any \r\ntool, takes some practice. It also reveals that making a form audibly accessible \r\ndoes take some care, and should be reviewed with a screen reader. My method \r\nfor hiding the honey pot URL field from the screen reader was effective, but my \r\noverall implementation to make it accessible needs more work.\r\n</p>',293,0,0,'CC-BY-SA','Spam,HTML,Forms,accessibility,screen reader',0,0,1),

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. \r\n</p>\r\n<p>\r\n<a href=\"https://play.google.com/store/apps/details?id=org.prowl.torque&hl=en_US&gl=US\">Torque Pro (OBD 2 and Car)</a><br />\r\nSee what your car is doing in realtime, get OBD fault codes, car performance, sensor data and more!\r\nTorque is a vehicle / car performance / diagnostics tool and scanner that uses an OBD II Bluetooth adapter to connect to your OBD2 engine management / ECU\r\n</p>\r\n<p>\r\n<a href=\"https://www.myg37.com/forums/engine-drivetrain-and-forced-induction/298338-vdc-stays-on-randomly.html\">Forum Thread</a>\r\n</p>\r\n<p>\r\n<a href=\"https://www.nicoclub.com/search#gsc.tab=0&gsc.q=infinity&gsc.sort=\">Search on NicoClub.com for Infinity Manuals</a>\r\n</p>\r\n',36,0,0,'CC-BY-SA','car,auto,odb2',0,0,1),

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.\r\n</p>\r\n<p>\r\nProduct development began in 2015. Two prototype test-flight satellites were launched in February 2018. 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.\r\n</p>\r\n<p>\r\nOn 15 October 2019, the United States Federal Communications Commission (FCC) submitted filings to the International Telecommunication Union (ITU) on SpaceX\'s behalf to arrange spectrum for 30,000 additional Starlink satellites to supplement the 12,000 Starlink satellites already approved by the FCC.\r\n</p>\r\n<p>\r\nAstronomers have raised concerns about the constellations’ effect on ground-based astronomy and how the satellites will add to an already jammed orbital environment. 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.\r\n</p>\r\n',243,0,0,'CC-BY-SA','internet, leo, satellites, ISP',0,0,1),

(3384,'2021-07-22','Page Numbers in EPUB eBook Files',1699,'Response to HPR 3367 I describe how to specify page numbers in an EPUB eBook.','<p>This episode is a response to <a href=\"https://hackerpublicradio.org/eps.php?id=3367\">hpr3367</a> 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.</p>\r\n\r\n<p>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 <a href=\"https://hackerpublicradio.org/eps.php?id=1512\">hpr1512</a>, 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.</p>\r\n\r\n<p>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.</p>\r\n\r\n<h3>Converting to EPUB 3</h3>\r\n\r\n<p>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 <code>Tools</code> menu and choose <code>Upgrade book internals</code>. This will create the new navigation file <code>nav.xhtml</code> to replace the old <code>toc.ncx</code> file. You\'ll need to edit this new file later to enable the page numbers.</p>\r\n\r\n<h3>Insert page anchors</h3>\r\n\r\n<p>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 <a href=\"https://hackerpublicradio.org/eps.php?id=1284\">Blather</a> 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:</p>\r\n\r\n<pre>\r\n<span epub:type="pagebreak" id="page57" title="57"></span>\r\n</pre>\r\n\r\n<h3>Page List in Navigation File</h3>\r\n\r\n<p>Finally you need to put a <strong>page list</strong> 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

(3386,'2021-07-26','What\'s for dinner?',1342,'Some scripts and a database for randomly choosing which meal to cook','<h2 id=\"overview\">Overview</h2>\r\n<p>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.</p>\r\n<p>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 <code>choose_meal</code>, 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!</p>\r\n<p>It wasn’t long before <code>choose_meal</code> was rewritten in <a href=\"https://www.perl.org/\" title=\"Perl scripting language\">Perl</a>. This time I decided to use a database, and chose <a href=\"https://www.sqlite.org/index.html\"><code>SQLite</code></a> to create it. My database contained just two tables, one for the meals themselves (called slightly confusingly <code>\'meal_history\'</code>), and another for a record of the choices made (called <code>\'meal_log\'</code>) – the ability to produce historical reports seemed like a desirable feature!</p>\r\n<p>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.</p>\r\n<p>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 <a href=\"https://gitlab.com/davmo/weekly_menus\" title=\"Weekly Menus repository\">GitLab repository</a> and the preparation of this show was begun.</p>\r\n<p>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.</p>\r\n<p>I might rethink this in the future however.</p>\r\n<h2 id=\"long-notes\">Long notes</h2>\r\n<p>Follow this link to <a href=\"https://hackerpublicradio.org/eps/hpr3386/full_shownotes.html\">read the detailed notes</a> associated with this episode.</p>\r\n<h2 id=\"links\">Links</h2>\r\n<ul>\r\n<li><p><a href=\"https://www.perl.org/\">Perl</a></p>\r\n<ul>\r\n<li><a href=\"https://www.perl.org/get.html\">Perl 5</a>: (currently v5.35.0)</li>\r\n<li><a href=\"https://www.raku.org/\">Raku</a>: originally called Perl 6, a totally different scripting language.</li>\r\n<li><a href=\"https://www.perl.com/article/announcing-perl-7/\">Perl 7</a>: updates to Perl 5, removal of some historical stuff</li>\r\n</ul></li>\r\n<li><p><a href=\"https://www.sqlite.org/index.html\">SQLite</a>: a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine.</p></li>\r\n<li><p><a href=\"https://gitlab.com/davmo/weekly_menus\">GitLab repository for <em>Weekly Menus</em></a></p></li>\r\n</ul>',225,0,1,'CC-BY-SA','Perl,SQLite3,database,food',0,0,1),

(3392,'2021-08-03','Structured error reporting',1714,'Tuula talks about how she improved build times by breaking down error reporting to smaller parts','<h2 id=\"initial-state\">Initial state</h2>\r\n<p>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:</p>\r\n<pre><code>-- | Error codes for all errors returned by API\r\ndata ErrorCode\r\n -- common error codes\r\n = ResourceNotFound\r\n | InsufficientRights\r\n | FailedToParseDataInDatabase\r\n -- errors specific to news\r\n | SpecialEventHasAlreadyBeenResolved\r\n | UnsupportedArticleType\r\n | SpecialNewsExtractionFailed\r\n | TriedToMakeChoiceForRegularArticle\r\n -- errors specific to simulation state\r\n | SimulationStatusNotFound\r\n | DeltaTIsTooBig\r\n | TurnProcessingAndStateChangeDisallowed\r\n | SimulationNotOpenForCommands\r\n | SimulationNotOpenForBrowsing\r\n -- errors specific to people\r\n | StatIsTooLow Text\r\n | CouldNotConfirmDateOfBirth\r\n | DateOfBirthIsInFuture\r\n | FirstNameIsEmpty\r\n | FamilyNameIsEmpty\r\n | CognomenIsEmpty\r\n | RegnalNumberIsLessThanZero\r\n -- errors specific to new person creation\r\n | AgeBracketStartIsGreaterThanEnd\r\n | PersonCreationFailed\r\n deriving (Show, Read, Eq)\r\n</code></pre>\r\n<p>Then I had some helper functions to turn any value of that type into a nice error message:</p>\r\n<pre><code>errorCodeToStatusCode :: ErrorCode -> Int\r\nstatusCodeToText :: Int -> ByteString\r\nerrorCodeToText :: ErrorCode -> Text\r\nraiseIfErrors :: [ErrorCode] -> HandlerFor App ()\r\n</code></pre>\r\n<p><code>errorCodeToStatusCode</code> was responsible for turning <code>ErrorCode</code> into http status code. For example <code>StatIsTooLow \"intrigue\"</code> would be <code>400</code>. <code>statusCodeToText</code> would take this code and turn it into short error message given in http response. <code>400</code> would be <code>Bad Request</code>. <code>errorCodeToText</code> would give a bit more verbose explanation of what happened, <code>StatIsTooLow \"intrigue\"</code> would be mapped to <code>\"Stat intrigue is too low\"</code>. Finally <code>raiseIfErrors</code> would take a list of <code>ErrorCode</code> 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:</p>\r\n<pre><code>[\r\n { code:\r\n { tag: "StatIsTooLow"\r\n , contents: "intrique"\r\n }\r\n , error: "Stat intrigue is too low"\r\n }\r\n]\r\n</code></pre>\r\n<p>There’s two tags: <code>code</code>, which contains machine readable details about the error and <code>error</code>, which contains error message that can be shown to user.</p>\r\n<p>While this worked fine, there was some problems with it. <code>ErrorCode</code> 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.</p>\r\n<h2 id=\"solution\">Solution</h2>\r\n<p>Breaking up the <code>ErrorCode</code> 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 <code>raiseIfErrors :: [ErrorCode] -> HandlerFor App ()</code> wanted a list of <code>ErrorCode</code> and elements in a list have to be of same type.</p>\r\n<p>I started by splitting <code>ErrorCode</code> to smaller types. Each of the smaller error types have automatically derived toJSON and fromJSON functions for serializing them to and from JSON:</p>\r\n<pre><code>data PersonCreationError =\r\n StatIsTooLow Text\r\n | CouldNotConfirmDateOfBirth\r\n | DateOfBirthIsInFuture\r\n | FirstNameIsEmpty\r\n | FamilyNameIsEmpty\r\n | CognomenIsEmpty\r\n | RegnalNumberIsLessThanZero\r\n deriving (Show, Re

(3396,'2021-08-09','Card roles in Magic the Gathering',2367,'There are over 25,000 cards in MTG. You only need 60 to play.','<p>Cutting to the chase:</p>\r\n<p>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.\r\n</p>\r\n\r\n<p>My list is by no means definitive, but I think these are the basic universal roles you need, regardless of how you play:</p>\r\n\r\n<ul>\r\n<li>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.</li>\r\n<li>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.<//i>\r\n<li>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.</li>\r\n<li>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.</li>\r\n</ul>\r\n\r\n<p>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.\r\n</p>\r\n\r\n<p>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 <a href=\"https://tappedout.net/mtg-decks/list-of-edh-draw-cards/\" target=\"_blank\">TappedOut.net</a> or <a href=\"https://magic.wizards.com/en/articles/archive/feature/top-50-card-drawing-cards-2003-03-21-0\" target=\"_blank\">magic.wizards.com</a>.</p>\r\n\r\n<p>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.\r\n</p>\r\n\r\n<p>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.</p>\r\n\r\n',78,0,0,'CC-BY-SA','magic, mtg, card, tcg',0,0,1),

(3408,'2021-08-25','Composting',336,'Inspired by episode 3157, Rho`n describes his experience of learning to compost','<h2 id=\"introduction\">Introduction</h2>\r\n<p>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.</p>\r\n<p>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].</p>\r\n<h2 id=\"kitchen-compost-bin\">Kitchen Compost Bin</h2>\r\n<p>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.</p>\r\n<h2 id=\"outside-compost-bin\">Outside Compost Bin</h2>\r\n<p>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).</p>\r\n<h2 id=\"my-composting-experience\">My Composting Experience</h2>\r\n<p>So far I h

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 <code>~/Music</code> directory which I talked about in 2013 (show <a href=\"https://hackerpublicradio.org/eps.php?id=1204\">1204</a>). The original scripts are still available on <a href=\"https://gitlab.com/davmo/magnatune-downloader\">GitLab</a> and I know of one other person who made use of them!</p>\r\n<p>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.</p>\r\n<p>It’s this <code>\'show_queue\'</code> script I am currently updating (called <a href=\"https://hackerpublicradio.org/eps/hpr3413/show_queue_orig\"><code>show_queue_orig</code></a>, 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 <code>grep</code> a pre-prepared summary in another file. This file of summaries had been made from a master XML file provided by Magnatune (see <code>update_albums</code> on GitLab).</p>\r\n<p>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.</p>\r\n<p>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 <a href=\"https://hackerpublicradio.org/eps/hpr3413/show_queue_db_1\"><code>show_queue_db_1</code></a> 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 <code>sqlite3</code> command in a loop, so I looked around for an alternative way.</p>\r\n<p>In April 2019 <a href=\"https://hackerpublicradio.org/correspondents/0311.html\">clacke</a> did a show (number <a href=\"https://hackerpublicradio.org/eps.php?id=2793\">2793</a>) about the Bash <code>coproc</code> command.</p>\r\n<p>This command creates a <em>subshell</em> running a command or group of commands which is connected to the calling (<em>parent</em>) process through two file descriptors (<em>FD</em>s). 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.</p>\r\n<p>I was vaguely aware of <code>coproc</code> 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.</p>\r\n<p>To solve my need to show my Magnatune queue of future purchases, it looked as if a <code>sqlite3</code> instance running in a subshell could be given queries one after the other and return the answers I needed. My journey to a Bash script using <code>coproc</code> then followed.</p>\r\n<h2 id=\"long-notes\">Long notes</h2>\r\n<p>Follow this link to <a href=\"https://hackerpublicradio.org/eps/hpr3413/full_shownotes.html\">read the detailed notes</a> associated with this episode.</p>\r\n<h2 id=\"links\">Links</h2>\r\n<ul>\r\n<li>Bash Reference Manual:\r\n<ul>\r\n<li><a href=\"https://www.gnu.org/software/bash/manual/bash.html#Coprocesses\">3.2.6 Coprocesses</a></li>\r\n<li><a href=\"https://www.gnu.org/software/bash/manual/bash.html#Duplicating-File-Descriptors\">3.6.8 Duplicating File Descriptors</a></li>\r\n</ul></li>\r\n</ul>\r\n<ul>\r\n<li>Stack Exchange:\r\n<ul>\r\n<li><a href=\"https://unix.stackexchange.com/questions/86270/how-do-you-use-the-command-coproc-in-various-shells\">How do you use the command coproc in v

I\'m using CentOS, but I\'ll admit that Debian is the easier option by far.</p>\r\n<p>Do this on 3 separate Pi units, each with the same specs.</p>\r\n<h2 id=\"set-hostnames\">Set hostnames</h2>\r\n<p>You must have unique hostnames for each Pi. Without unique hostnames, your cluster cannot function.</p>\r\n<p>There are several \"kinds\" of hostnames, so to avoid confusion I change all of them.</p>\r\n<p>I use a simple naming scheme: <code>k</code> for \"kubernetes\" + an integer, starting at 100 + <code>c</code> for \"cluster\":</p>\r\n<pre class=\"bash\"><code>$ sudo hostname k100c\r\n$ sudo sysctl kernel.hostname=k100c\r\n$ sudo hostnamectl set-hostname k100c\r\n$ sudo reboot\r\n</code></pre>\r\n<p>Do this for each Pi. At a minimum, you end up with Pi computers named k100c, k101c, and k102c.</p>\r\n<h2 id=\"set-verbose-prompts\">Set verbose prompts</h2>\r\n<p>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 <code>~/.bashrc</code> of each Pi:</p>\r\n<pre><code>export PS1=\'\\[\033[1;32m\\]\\! \\d \\t \\h:\\w \\n% \\[\033[00m\\]\' \r\n</code></pre>\r\n<h2 id=\"install-a-pi-finder-script\">Install a Pi finder script</h2>\r\n<p>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 <a href=\"https://opensource.com/article/20/6/find-raspberry-pi\">Use this script to find a Raspberry Pi on your network</a>, which explains how to run it.</p>\r\n<pre class=\"bash\"><code>#!/bin/bash\r\n\r\nset -o errexit\r\nset -o nounset\r\n\r\ntrap quit INT TERM\r\n\r\nCOUNT=0\r\nLED="/sys/class/leds/led0"\r\n\r\nif !

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.</p>\r\n<p>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.</p>\r\n<pre class=\"bash\"><code>[k100c]$ curl -sfL https://get.k3s.io -o install_k3s.sh\r\n[k100c]$ chmod 700 install_k3s.sh\r\n</code></pre>\r\n<p>Read the script to ensure that it seems to do what you expect, and then:</p>\r\n<pre class=\"bash\"><code>[k100c]$ ./install_k3s.sh\r\n</code></pre>\r\n<p>After installation, you\'re prompted to add some arguments to your bootloader. Open <code>/boot/cmdline.txt</code> in a text editor and add <code>cgroup_memory=1 cgroup_enable=memory</code> to the end of it.</p>\r\n<pre class=\"text\"><code>console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p3 rootfstype=ext4 elevator=deadline rootwait cgroup_memory=1 cgroup_enable=memory\r\n</code></pre>\r\n<p>Reboot:</p>\r\n<pre class=\"bash\"><code>[k100c]$ sudo reboot\r\n</code></pre>\r\n<p>Once the Pi is back up, verify that yo

(3442,'2021-10-12','What is this thing called science',790,'Critical thinking is only part of the equation. Here\'s the other part.','<hr />\r\n<h3>Counter Point</h3>\r\n<p>This show is a counter point to: <a href=\"https://hackerpublicradio.org/eps.php?id=3414\">hpr3414 :: Critical Thinking may make You Critical of the Covid Crisis</a>\r\n</p>\r\n<hr />\r\n\r\n<p>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?</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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.</p>\r\n<p>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!</p>\r\n<p>Yeah it turns out that computers are the product of science, and in fact building computers and programming comput

(3443,'2021-10-13','Neuton battery replacement',593,'Rho`n describes replacing the battery in his Neuton EM 4.1 electric lawn mower','<h1 id=\"audio-notes\">Audio Notes</h1>\r\n<p>During the audio I repeatedly called it the Neutron mower instead of the Neuton mower. I was too lazy edit those mispronunciations.</p>\r\n<h1 id=\"introduction\">Introduction</h1>\r\n<p>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.</p>\r\n<h1 id=\"replacing-parts\">Replacing Parts</h1>\r\n<p>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 <a href=\"https://www.neutonpower.com/\">Neuton website</a> 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.</p>\r\n<p>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.</p>\r\n<h1 id=\"conclusion\">Conclusion</h1>\r\n<p>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.</p>\r\n<h1 id=\"references\">References</h1>\r\n<ul>\r\n<li>Neuton CE5.4 24 volt rechargeable battery CASE ONLY - <a href=\"https://www.ebay.com/itm/114952181341\">EBay item</a></li>\r\n<li>Mighty Max Battery 12V 10AH Replaces HE12V127 HGL1012 LCRB1210P NEUTON CE5 POWPS12100 Battery - 2 Pack Brand Product - <a href=\"https://www.amazon.com/gp/product/B00K9713L4/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1\">Amazon item</a></li>\r\n</ul>\r\n<h1 id=\"attribution\">Attribution</h1>\r\n<p>The transition sound used between audio clips is found on <a href=\"https://freesound.org/\">freesound.org</a>:<br />\r\nName: <a href=\"https://freesound.org/people/DanJFilms/sounds/529064/\">Harp Transition Music Cue</a><br />\r\nAuthor: <a href=\"https://freesound.org/people/DanJFilms/\">DanJFilms</a><br />\r\nLicense: <a href=\"https://creativecommons.org/publicdomain/zero/1.0/\">Creative Commons Zero</a></p>\r\n',293,0,0,'CC-BY-SA','electric lawnmower,lawnmower,rechargeable battery',0,0,1),

This is a follow up to <a href=\"https://hackerpublicradio.org/eps.php?id=3443\">episode 3443</a>. 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.</p>\r\n<h2 id=\"testing-the-mower\">Testing the mower</h2>\r\n<p>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.</p>\r\n<h2 id=\"references\">References</h2>\r\n<ul>\r\n<li>DR Neuton Cordless Walk Behind 14\" Lawn Mower CE2 CE3 CE5 Reset Security Key - <a href=\"https://www.ebay.com/itm/184176055409?ViewItem=&item=184176055409\">EBay item</a></li>\r\n</ul>\r\n<h2 id=\"attribution\">Attribution</h2>\r\n<p>The transition sound used between audio clips is found on <a href=\"https://freesound.org/\">freesound.org</a>:<br />\r\nName: <a href=\"https://freesound.org/people/DanJFilms/sounds/529064/\">Harp Transition Music Cue</a><br />\r\nAuthor: <a href=\"https://freesound.org/people/DanJFilms/\">DanJFilms</a><br />\r\nLicense: <a href=\"https://creativecommons.org/publicdomain/zero/1.0/\">Creative Commons Zero</a></p>',293,0,0,'CC-BY-SA','electric lawnmower,lawnmower,rechargeable battery',0,0,1),

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.</p>\r\n',129,0,0,'CC-BY-SA','podcasts, dowloads',0,0,1),

I think I have found a solution to them. Unfortunately, this show was recorded before I discovered it.</p>\r\n<h2>Synopsis</h2>\r\n<p>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.</p>\r\n\r\n<p>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 <a href=\"#dd\">dd</a> to do a sector-by-sector copy)</p>\r\n\r\n<p>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.</p>\r\n\r\n<h2>References</h2>\r\n\r\n<ul>\r\n <li><a href=\"https://clonezilla.org/\">Clonzilla website</a></li>\r\n <li><a href=\"https://unetbootin.org/\">UNETBOOTIN website</a></li>\r\n <li><a id=\"dd\" href=\"https://en.wikipedia.org/wiki/Dd_(Unix)\">dd</a>, command line utility for *nix like operating systems</li>\r\n</ul>\r\n\r\n<h2>Attribution</h2>\r\n\r\n<p>The transition sound used between audio clips is found on <a href=\"https://freesound.org/\">freesound.org</a>:<br>\r\nName: <a href=\"https://freesound.org/people/DanJFilms/sounds/529064/\">Harp Transition Music Cue</a><br>\r\nAuthor: <a href=\"https://freesound.org/people/DanJFilms/\">DanJFilms</a><br>\r\nLicense: <a href=\"https://creativecommons.org/publicdomain/zero/1.0/\">Creative Commons Zero</a></p>\r\n\r\n',293,0,0,'CC-BY-SA','Clonezilla,backup,backups,cloning,hard drives',0,0,1),

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.</p>\r\n<p>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 <a href=\"https://www.baofengradio.com/products/uv-5rtp\">Baofeng UV-5RTP</a> [<a href=\"https://www.amazon.co.uk/dp/B07PWGMT13\">Amazon UK</a>], I joined the <a href=\"https://rsgb.org/\">Radio Society of Great Britain</a> (not a requirement, but I would recommend it), signed up for Essex Ham\'s <a href=\"https://www.essexham.co.uk/train/online-exams/\">Foundation Training Course</a> (not a requirement, but strongly recommended as it\'s geared around the examination, and it\'s free!)</p>\r\n<p>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 <a href=\"https://en.m.wikipedia.org/wiki/Ofcom\">Ofcom</a> (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.</p>\r\n<p>Anyhoo, once I got my Foundation licence, I went out that Sunday to log some contacts, or <a href=\"https://en.m.wikipedia.org/wiki/Contact_(amateur_radio)\">QSO</a>s. 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 <a href=\"https://en.m.wikipedia.org/wiki/CQ_(call)\">CQ</a> - essentially a way of saying \"I want to talk to somebody\" - \"Seek You\". As part of the licence condi

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.

(3486,'2021-12-13','Unleash the true potential of GNU nano text editor',516,'Turn GNU nano text editor into a fancy, good looking & powerful editor','<p>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 <code>GNU nano</code>. So what exactly is this <code>nano</code> text editor? Well, according to documentation available on <code>GNU nano</code>\'s <a href=\"https://nano-editor.org/\">website</a>,</p>\r\n<blockquote>\r\n<p>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\".</p>\r\n</blockquote>\r\n<p>Pico and Pine email suites are still around so what was the need to create <code>nano</code> 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 <code>nano</code>. 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 <code>nano</code> 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 <code>nano</code> is 1000 times larger than pico. In February 2001, <code>nano</code> 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 <a href=\"https://hackerpublicradio.org/eps.php?id=3454\">HPR episode 3453 - Engineering notation</a> by Ken Fallon.</p>\r\n<p><code>nano</code> 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 <code>nano</code> 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. <code>nano</code> 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 <code>nano</code>\'s cool features are disabled by default. This results in <code>nano</code> 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 <code>nano</code> and make it shine. Are you ready? Great! Let\'s do it together then!</p>\r\n<p>First thing we need to to do is create a file with the name <code>.nanorc</code> in the <code>$HOME</code> directory. Open your terminal emulator and run,</p>\r\n<pre class=\"text\"><code>touch $HOME/.nanorc\r\n</code></pre>\r\n<p>We\'d also need to create a directory called <code>Nano_Backups</code> in our <code>Documents</code> directory. To do so run the following command,</p>\r\n<pre class=\"text\"><code>mkdir -p $HOME/Documents/Nano_Backups\r\n</code></pre>\r\n<p>Next open that <code>.nanorc</code> file and simply paste the following content in it,</p>\r\n<pre class=\"text\"><code>set atblanks\r\nset autoindent\r\nset backup\r\nset backupdir "/home/USERNAME/Documents/Nano_Backups"\r\nset boldtext\r\nset constantshow\r\nset cutfromcursor\r\nset indicator\r\nset linenumber
