This is about UNIX, not Multics. Maybe I\'ll come back to it.</p>\n<h1 id=\"philosophy-implementations-ducks\">Philosophy, implementations, ducks</h1>\n<p>When I think of \"UNIX\", I do not think of the trademark. Instead, I think of the <a href=\"https://en.wikipedia.org/wiki/Unix_philosophy\">Unix philosophy.</a> and the general design principles, interface, and behavior of a UNIX system.</p>\n<p>A better way of thinking about \"UNIX\" is as something \"POSIX-like\" rather than \"AT&T\'s commercial UNIX\". Example: although Linux and GNU are overly complicated, they pass the duck test for being a UNIX. Pedigree or not, you know a nix when you see one.</p>\n<p>Also, when I say \"UNIX\", I mean \"Free UNIX\". I have no interest in proprietary implementations that only exist for the purpose of restricting users and disempowering/discouraging sysadmins from becoming self-reliant.</p>\n<p>So what is the philosophy?</p>\n<ul>\n<li>Do one thing and do it well</li>\n<li>Design programs that work together using text as the common interface</li>\n<li>KISS: Keep it simple, stupid</li>\n<li>Test early, test often</li>\n</ul>\n<p>And additionally:</p>\n<ul>\n<li>everything is a file or a process</li>\n</ul>\n<h1 id=\"design\">Design</h1>\n<h2 id=\"10000-ft-view\">10,000 Ft View</h2>\n<p>UNIX is a multiuser time sharing networked operating system, running as an always online service. A UNIX system is a single mainframe computer running an operating system designed for multiple users to access concurrently over the network, equally (depending on implementation) sharing resources amongst the active users.</p>\n<p>In a traditional network setup, there is one mainframe UNIX machine with multiple dumb terminals connected to it over the network. None of the users touch the mainframe physically. Instead, they interact with it exclusively through their own dumb terms. These dumb terminals have minimal or no computing power of their own because all of the actual computation takes place on the mainframe. Built in networking is a given.</p>\n<p>As for the actual software running on the mainframe, it\'s quite simple to visualize. A Unix system is a flexible but organized stack of concepts, each depending on the concept below, all working together for the sole purpose of enabling the end user to play video games and watch videos online.</p>\n<pre><code> / user applications \\\n / shells \\\n / daemons \\\n / file systems \\\n / kmods/drivers \\\n / syscalls \\\n / kernel \\\n/ hardware \\\n</code></pre>\n<p>In order to fully explain why UNIX is sublime, I will start from the bottom and work my way upward. Before I discuss the shell, I will explain the multiuser aspects of the system. Then, after a long arduous journey of verbosity, explain how to actually use the thing.</p>\n<h2 id=\"kernel\">Kernel</h2>\n<p>The kernel is something the user rarely interacts with. It abstracts all the hard parts away from the user. No more poking random memory addresses to load a program from tape.</p>\n<h3 id=\"multitasking\">Multitasking</h3>\n<p>In order tLine truncated

Bright colors, distracting thumbnails, peanut galleries, etc. I prefer to consume my videos in the same way I consume everything else: via RSS.</p>\n<p>RSS is my favorite way of aggregating things that other people have made because it allows me, the user, to interact with their things</p>\n<p>The only dependencies not on a standard UNIX system are <code>newsboat</code> and a video player. I also use <code>yt-dlp</code> to download videos for later viewing. I like <code>mpv</code> but you can substitute your own.</p>\n<pre><code>$ sudo $pkgmrg install newsboat mpv yt-dlp</code></pre>\n<h1 id=\"getting-rss-feeds-from-youtube\">Getting RSS feeds from youtube</h1>\n<p>Youtube (currently) provides RSS feeds for channels.</p>\n<h2 id=\"finding-youtube-channel-id\">Finding Youtube channel ID</h2>\n<p>Sometimes channels have vanity URLs that can make it difficult to find the channel ID. Other times, the URL contains the channel ID. All youtube channel IDs start with the string <code>UC</code> so we can easily grep for them.</p>\n<pre><code>$ curl https://www.youtube.com/c/RMCRetro | grep --color "href=\\"https://www.youtube.com/channel/UC\\""\n[ lots of nonsense ]\nhref="https://www.youtube.com/channel/UCLEoyoOKZK0idGqSc6Pi23w"\n[ lots of nonsense ]</code></pre>\n<p>In order to turn this channel ID into something useful, we create the following URL:</p>\n<pre><code>https://www.youtube.com/feeds/videos.xml?channel_id=UCLEoyoOKZK0idGqSc6Pi23w</code></pre>\n<p><a href=\"https://takeout.google.com/\">Google takeout can also be used to export youtube subscriptions.</a></p>\n<p>The export format is a CSV that contains the channel IDs for all of our subscriptions.</p>\n<pre><code>Channel Id,Channel Url,Channel Title\nUCLEoyoOKZK0idGqSc6Pi23w,http://www.youtube.com/channel/UCLEoyoOKZK0idGqSc6Pi23w,RMC - The Cave</code></pre>\n<h1 id=\"newsboat-url-list\">Newsboat url list</h1>\n<p>Newsboat reads it’s list of URLs from <code>~/.config/newsboat/urls</code>. Every url we add to this list will be automaticlly fetched. You can make separate URL lists for your list of videos and list of standard text based RSS feeds</p>\n<p>If you have an exported CSV, you can easily modify it so that newsboat will accept it as a list of URLs by deleting row 1, column 1+comma, and replacing the comma between the URL and channel name with a tab character. Doing a <code>sed \'s/channel\\//feeds\\/videos.xml?channel_id=/g\'</code> on the file is an easy way to replace the website URL with the feed url. Newsboat only reads the first field of every row so the channel name can be kept for easier subscription management.</p>\n<pre><code>http://www.youtube.com/feeds/videos.xml?channel_id=UCLEoyoOKZK0idGqSc6Pi23w RMC - The Cave</code></pre>\n<h1 id=\"newsboat-config\">Newsboat config</h1>\n<p>In order to play videos, we need to add some macros to the newsboat config file at <code>~/.config/newsboat/config</code></p>\n<p>Mine looks like this.</p>\n<pre><code># load URLS on launch\nauto-reload yes\n\n# vim binds\nbind-key j down\nbind-key k up\nbind-key j next articlelist\nbind-key k prev articlelist\nbind-key J next-feed articlelist\nbind-key K prev-feed articlelist\nbind-key G end\nbind-key g home\nbind-key d pagedown\nbind-key u pageup\nbind-key l open\nbind-key h quit\nbind-key a toggle-article-read\nbind-key n next-unread\nbind-key N prev-unread\nbind-key D pb-download\nbind-key U bashow-urls\nbind-key x pb-delete\n\n# macro setup\nbrowser linkhandler\nmacro , open-in-browser\n\n# launch video player\nmacro v set browser "setsid -f mpv" ; open-in-browser ; set browser linkhandler\n\n# download video\nmacro d set browser "yt-dlp"; open-in-browser ; set browser linkhandler\n\n# download audio only\nmacro a set browser "yt-dlp --embed-metadata -xic -f bestaudio/best" ; open-in-browser ; set browser linkhandler</code></pre>\n<h1 id=\"video-demo\">Video demo</h1>\n<p>This is a demo of using newsboat with videos.

We\'ve been making\nsmall adjustments to our audio mix each month in order to get the best\npossible sound. Its been especially challenging getting all of our\nvoices relatively level, because everyone has their own unique setup.\nMumble is great for bringing us all together, and for recording, but\nit\'s not good at making everyone\'s voice the same volume. We\'re pretty\nhappy with the way this month\'s show turned out, so we\'d like to share\nour editing process and settings with you and our future selves (who, of\ncourse, will have forgotten all this by then).</p>\n<p>We use the \"Truncate Silence\" effect with it\'s default settings to\nminimize the silence between people speaking. When used with it\'s\ndefault (or at least reasonable) settings, Truncate Silence is extremely\neffective and satisfying. It makes everyone sound smarter, it makes the\nfile shorter without destroying actual content, and it makes a\nconversations sound as easy and fluid during playback as it was while it\nwas recorded. It can be even more effective if you can train yourself to\nremain silent instead of saying \"uuuuummmm.\" Just remember to ONLY pass\nthe file through Truncate Silence ONCE. If you pass it through a second\ntime, or if you set it too aggressively your audio may sound sped up and\nchoppy.</p>\n<p>Next we use the \"Compressor\" effect with the following settings:</p>\n<pre><code>Threshold: -30db\n\nNoise Floor: -50db\n\nRatio: 3:1\n\nAttack Time: 0.2sec\n\nDecay Time: 1.0 sec`</code></pre>\n<p>\"Make-up Gain for 0db after compressing\" and \"compress based on\npeaks\" were both left un-checked.</p>\n<p>After compressing the audio we cut any pre-show and post-show chatter\nfrom the file and save them in a separate file for possible use as\nouttakes after the closing music.</p>\n<p>We adjust the Gain so that the VU meter in Audacity hovers around\n-12db while people are speaking, and we try to keep the peaks under\n-6db, and we adjust the Gain on each of the new tracks so that all\nvolumes are similar, and more importantly comfortable. Once this is done\nwe can \"Mix and Render\" all of our tracks into a single track for exLine truncated

When SystemD was a hot\ntopic of debate, many became irrational over it, but I want to start by\nsaying that I don\'t think it\'s a bad technology. I think it is a rather\ngood technology. I just don\'t want it on my personal computer. So I\nwould like to run things down in this order: what is it (as in, what is\nit really,) what makes it a good technology, why I don\'t want it now\n(but might later,) and a few tips for you if you decide that you don\'t\nwant it currently.</p>\n<p>SystemD Is not an init system. SystemD includes an init system.\nSystemD Init was faster than SysVInit, but SystemD Init isn\'t the\nfastest init system, and SysVInit now has a parallelization helper, at\nleast on Debian.</p>\n<p>So, if SystemD Init is not SystemD, than what is SystemD? To\nunderstand this we must first understand something about Linux. Linux\noperates under a model where there are root processes, and there are\nuser processes. These two kinds of processes are usually called\n\"layers.\" SystemD is actually a third layer, that can be called a system\nlayer. So when SystemD is added to a Linux system, that changes the\nsystem so that there are three layers, a root layer, a user layer, and a\nsystem layer. As such, you now ask SystemD to set how the system runs.\nThis is why SystemD includes things like an init system, because if you\nwant to change what the system is running, you ask SystemD to change it.\nSystemD then messages an appropriate system to implement the change,\nlike messaging its init system to bring up or bring down a system\ndaemon. Once you play out this in your head a bit, you really realize\nthat SystemD acts more like a message passing system in this regard.</p>\n<p>So why do I say SystemD is a good technology? Because this can\nstandardize system control. Without SystemD a fleet of computers becomes\nlike individual fingerprints or unique snowflakes. If you manage many\ncomputers, as many professional IT people do, you want them to all run\nthe same, all have the same profiles and general configurations. So if\nyou have a bunch of computers you are running, you can run a lot more if\nthey are all run the same way. If your job requires you to run 10,000\nwebservers, you want them to run identically because it is impossible to\nkeep an understanding of 10,000 unique configurations in a human\nhead.</p>\n<p>SystemD really shines in its support of virtualization as well. So\nto speak of servers, I used to run an email server for a few friends.\nEach of us had a userid and number as unix users. The mapping of unix\nuserids and postfix userids can get confusing when it gets big. Thanks\nto SystemD\'s virtualization work, you can actually put a service like\nemail into a namespace situation so that it has only the users root and\nthe daemon user id (like \"postfix\"), so SystemD greatly enhances\nsecurity for server installations. This might help explain its\ndominance in linux distributions that have been traditionally\nserver-centric, such as debian and redhat.</p>\n<p>So why don\'t I don\'t want it? Well, I\'ve been doing a lot of talking\nabout professional computer work and corporate work environments, but I\nuse a \"Personal Computer\" as a hobby. I\'ve been out-of-industry for\ndecades now. And when I say \"Personal Computer\" I\'m not talking a\nhardware specification, rather I\'m talking about \"This is my personal\ncomputer where I do things my way, as opposed to my work computer where\nI do things my companies way\". Dear listener, please remember that I did\nthe first community show contribution to HPR, and my topic was about\npersonalization. For me, a hobbyist interested in operating system\nexperimentation, I don\'t want a system layer, I want a traditional\nunix-like system that operates on a two-layer model and does things my\nway, nobody else\'s way.</p>\n<p>So, what advice can I give to those who don\'t want SystemD now? Well,\nrecently I\'ve left Debian. Debian, you see, supports init system\ndiversity, but as you now know dear listener, that is different than\nbeing without SystemD. You may have heard that SystemD is\nlinux-specific, that is to say that it runs only on linux, not anything\nlike a BSD system or a Windows system. But you may be curious to know\nthat it is also Gnu-libC specific. Which means that the C compiler must\nuse GNU\'s libC standard library.

Not for production use.','<p>Show notes</p>\n<ul>\n<li>\n<p>No clear mark of when friendship starts</p>\n</li>\n<li>\n<p>often feels \"right\" when mutual</p>\n</li>\n<li>\n<p>to some people friendship is a persistent state. once you have it, it's forever unless explicitly dissolved.</p>\n</li>\n<li>\n<p>for other people, it's something requiring maintenance. arguable this suggests that there are degrees of friendship, based on when you last spoke to one another.</p>\n</li>\n<li>\n<p>degrees of friendship also suggests progression. friend → close friend → best friend.</p>\n</li>\n</ul>\n<h2 id=\"_how_to_make_a_friend\">how to make a friend</h2>\n<p>friendship requires communication.</p>\n<ul>\n<li>\n<p>start by communicating in some way that makes the other person feel not unpleasant</p>\n</li>\n<li>\n<p>you're not supposed to target a friend. this can be a frustrating rule, because if you're trying to make a friend, you have to target somebody, but the general consensus is that you're not supposed to \"try too hard\". target lots of people in the hopes of stumbling across somebody to befriend.</p>\n</li>\n<li>\n<p>complimenting something they have done, even if it's something simple like wearing a cool shirt, is a very easy start</p>\n</li>\n<li>\n<p>finding ground common allows for repeated communication</p>\n</li>\n<li>\n<p>repetition of this is what builds friendship. this is why friendships often develop at work, but can dissolve quickly after a job change.</p>\n</li>\n<li>\n<p>the situation matters. chatting with someone who's being paid to interact with you, like somebody working at a store, doesn't count because in context they more or less cannot choose to stop communicating with you until you leave the store. chatting with someone who has anything to gain by chatting with you doesn't count (like an intern at work).</p>\n</li>\n<li>\n<p>to speed up a developing friendship, you can invite the person to interact with you on something with a clearly defined goal. You like coding? I like coding! Would you care to collaborate for 4 hours on a script that would help me find my Raspberry Pi on my network?</p>\n</li>\n<li>\n<p>during the activity, continue to communicate. this can be difficult because you're doing an activity that you both claim to enjoy, so in theory the activity should be sufficient to further the friendship. However, the activity doesn't build the friendship, it only builds a partnership. It's the communication that builds friendship.</p>\n</li>\n</ul>\n<p>unfortunately, there's no clear point during this process at which you know you have made a friend. so you have to define what a friend is, to you, and then work toward that goal.</p>\n<p>Here are some examples of definitions for friendship. There is no right or wrong here, it's really just setting your own expectations and requirements:</p>\n<ul>\n<li>\n<p>A friend is someone to hang out with on sundays.</p>\n</li>\n<li>\n<p>A friend is someone I can call when I've got some free time to kill.</p>\n</li>\n<li>\n<p>A friend is someone I can play video games with online.</p>\n</li>\n<li>\n<p>A friend is someone I can call, day or night, when I need help.</p>\n</li>\n<li>\n<p>A friend is someone who has come over for dinner, and has met my family, and who I see at least once a month.</p>\n</li>\n</ul>\n<p>There's no official definition, so you must define it yourself.\nYour definition may differ from the other person's definition.\nYou might say \"we are best friends\" but they might say \"no, I already have a best friend, but you're a <em>good</em> friend\" and THAT'S OK.</p>\n<p>If it helps, classify what kinds of friends you have so you understand what kinds of relationships you are maintaining.\nCommunicate with your friends, even if it's only to let them know that you're bad at communicating on a regular basis, or ask them how frequently they need to communicate to maintain a healthy friendship.</p>\n',78,108,0,'CC-BY-SA','autism,friendship,relationship,social engineering',0,0,1),
