I am using it for memorizing Vietnamese words in my endeavor to learn Vietnamese.</p> <p>I am currently running Anki 2.1.16 on OpenBSD 7.1. Unfortunately, quite often Anki freezes after using it for some time, without any advance notice. When this happens, I can no longer do anything except moving the mouse pointer. I cannot switch windows and not even switch to the console in order to forcefully quit Anki. Apparently, it crashes the whole system, and the only way out is a forceful reboot.</p> <p>I do not know what causes this behavior or if there is any fix for it. It seems that I am not the only one experiencing this, but I have not yet found a solution to this behavior.</p> <p>I did find a workaround, however: Running Anki inside of <a href="https://man.openbsd.org/Xephyr">Xephyr(1)</a> (a nested X server that runs as an X application and is part of OpenBSD base) seems to prevent it from freezing. The workaround involves three steps:</p> <ol> <li>Launch <code>Xephyr</code> on display <code>:1</code> (or any other display differing from your main display, which is usually <code>:0</code>).</li> <li>Launch <code>cwm</code> inside the <code>Xephyr</code> window just created (it is necessary to run a window manager since Anki employs multiple windows in general; of course, any other window manager can be used as well).</li> <li>Lauch Anki inside the <code>Xephyr</code> window.</li> </ol> <p>For convenience, I have created a small shell script for executing these steps:</p> <pre><code>Xephyr -br -ac -noreset -screen 1920x1080 :1 &amp; cwm -c .cwmrc_xephyr -d :1 &amp; DISPLAY=:1 anki &amp; </code></pre> <p>Of course, the value of the <code>screen</code> command line parameter of <code>Xephyr</code> needs to be adjusted to your screen size. Also, I run <code>cwm</code> in the <code>Xephyr</code> window with a specific configuration file.</p> <p>It works well, but strangely, after a while <code>cwm</code> seems to stop running inside <code>Xephyr</code>. This is inconvenient because it makes it impossible to switch between different Anki windows. The solution is to simply restart <code>cwm</code> by manually executing the second line of the script again.</p> <p>Obviously, this is not a real fix to the problem, but it works. Hopefully, Anki will get more stable in the future so that this workaround will no longer be needed.</p> <p>The Melancholy of the Day</p> https://thorstenzoeller.com/day 2023-02-11 2023-02-11 <h1 id="the-melancholy-of-the-day">The Melancholy of the Day</h1> <p>2023-02-11</p> <p>A new day begins, in the dark, in silence. Everything is still asleep; there is barely any activity, any motion. It is a state of peace and serenity. There is nothing to accomplish, no hustle and bustle; everything is immersed in stillness.</p> <p>Then, the sun begins to rise, and slowly the world awakens from its sleep. Not much is happening yet, but the new day is full of potential, full of opportunities. An atmosphere of departure prevails. Everything seems possible, nothing impossible. As the sun continues to rise, a tension develops, as the inactivity of the night wants to release itself into activity.</p> <p>Around noon, when the sun is highest in the sky, the day is most powerful. Glittering light falls from the outside into the rooms; light which is so strong that it blinds. The day is now bursting with energy. Everything is possible, and no end of this state is conceivable.</p> <p>But then comes the afternoon, and slowly, very slowly, the sun begins its descent. At first barely visible, it does not take long until it becomes clear that the day cannot maintain its power. First shades emerge, and the light is no longer as glittering as it was before; it is slightly dimmer now than just a short time ago. And it is constantly changing. It becomes ever softer and warmer the deeper the sun is in the sky. It still fills the rooms, but instead of dominating them, it becomes tender. The light immerses everything in dim, warm colors, and the shades become longer and longer. It is a mystical, almost magical atmosphere which now accrues.</p> <p>But this change of light, of the mood, is accompanied by a certain melancholy, and the melancholy grows the longer the day lasts and the fainter the light becomes. The steady change of light, proceeding faster and faster, leaves no doubt that the end of the day approaches. Some time still remains, but it seeps away quickly, second for second, minute for minute. The time when the day seemed invincible is now long gone; long gone is the time when it seemed that the day would prevail forever. It is absolutely clear now that it will be over soon. It had just brimmed over with power, with self-confidence, with energy–but now it becomes weaker and ever weaker, and very soon it will be history and forever, irretrievably gone.</p> <p>Michael W Lucas: “Ed Mastery”</p> https://thorstenzoeller.com/ed-mastery 2024-09-29 2024-09-29 <h1 id="michael-w-lucas-ed-mastery">Michael W Lucas: “Ed Mastery”</h1> <p>2024-09-29</p> <p>The average user may not think a lot about which text editor to use. For us, however, the choice of a text editor is a very serious matter.</p> <p>I’ll admit it: I have always felt a little proud to be a <a href="https://man.openbsd.org/vi">vi(1)</a> user (I even have a dedicated <a href="/vi/">vi page</a> on my website). After having read <a href="https://mwl.io/nonfiction/tools#ed">Ed Mastery</a> by <a href="https://mwl.io/">Michael W Lucas</a>, however, I feel somewhat whimpy about it.</p> <p>Only recently did I stumble across the book, and I was surprised that a book about <a href="https://man.openbsd.org/ed">ed(1)</a> – “the standard Unix text editor” – even exists. Yet, I knew immediately that I would have to read it. The mere existence of a book about <a href="https://man.openbsd.org/ed">ed(1)</a> was enough to convince me that it will be worth it.</p> <p>And I was not disappointed (not that I had expected that…). Michael W Lucas’ style of writing is hilarious, and first and foremost, it is simply a pleasure to read.</p> <p>Admittedly, I never really looked past <a href="https://man.openbsd.org/vi">vi(1)</a> in the history of Unix text editors. I roughly new that <a href="https://man.openbsd.org/ex">ex(1)</a> and <a href="https://man.openbsd.org/ed">ed(1)</a> are predecessors of <a href="https://man.openbsd.org/vi">vi(1)</a> and that they are line editors, but they always seemed a bit too peculiar and exotic to me to justify looking into them in more detail (mostly because they are line editors, stemming from a time when monitors were not yet common or even available – one cannot take a line editor seriously these days, can one?). While I always felt that no real progression has taken place in editor development since the advent of <a href="https://man.openbsd.org/vi">vi(1)</a> (which explicitly includes editors like <a href="https://www.vim.org/">Vim</a> or <a href="http://neovim.io/">Neovim</a>), I always implicitly assumed that <a href="https://man.openbsd.org/vi">vi(1)</a> <em>was</em> in fact a progression from <a href="https://man.openbsd.org/ed">ed(1)</a> and <a href="https://man.openbsd.org/ex">ex(1)</a> (reflecting the progression from line printers to monitors for displaying output). After reading <a href="https://mwl.io/nonfiction/tools#ed">Ed Mastery</a>, though, I am not so certain about it anymore. I thought <a href="https://man.openbsd.org/vi">vi(1)</a> was the pinnacle of simplicity, beauty and efficiency, but maybe I was wrong all along.</p> <p>A while ago, there was a great post titled <a href="https://stackoverflow.com/a/1220118">Your problem with Vim is that you don’t grok vi.</a> on Stack Overflow (read it if you haven’t yet!). It basically states that many of the features of <a href="https://www.vim.org/">Vim</a> that are generally considered improvements over <a href="https://man.openbsd.org/vi">vi(1)</a> (<em>Vi IMproved</em>, you know?), making it more “user friendly”, are in fact feature creep (visual mode? why?) and simply exist because users don’t want to take the time to get really familiar and acquainted with <a href="https://man.openbsd.org/vi">vi(1)</a>. It is the antidote to Antoine de Saint-Exupéry’s famous statement “Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.”<sup id="fnref:1"><a href="#fn:1" class="footnote" rel="footnote" role="doc-noteref">1</a></sup></p> <p>I am wondering if something similar could not be said about <a href="https://man.openbsd.org/ed">ed(1)</a> as well: “Your problem with vi is that you don’t grok ed.”</p> <p>In any event, after reading <em>Ed Mastery</em>, many known features from <a href="https://man.openbsd.org/vi">vi(1)</a> will make more sense. And even though it is rather unlikely that most users will ditch their editor of choice right away in favor of <a href="https://man.openbsd.org/ed">ed(1)</a> after reading the book, I am convinced that it will improve your editing skills (if you use an editor descending from <a href="https://man.openbsd.org/ed">ed(1)</a>, that is – otherwise, all hope is lost anyway).</p> <p>In summary: Experiencing joy while reading the book and learning profound things along the way: What more could you wish for from a book?</p> <p>Therefore my recommendation: <a href="https://mwl.io/nonfiction/tools#ed">Get the book</a>, read it and grok <a href="https://man.openbsd.org/ed">ed(1)</a>, now!</p> <p><em>Note:</em> Peter N. M. Hansteen has already written <a href="https://nxdomain.no/~peter/ed_mastery_is_a_must_for_real_unix_person.html">a great review</a> of the book several years ago, and actually I feel that there is not much I could add to it (apart from my casual ranting you spent the last couple of minutes reading).

A big “thank you” to Hyde for coming up with this great idea, organizing the carnival and hosting the <a href="https://lazybea.rs/vim-carnival-202509/">first one</a>!</p> <p><em>Note: In the whole article, I am mostly using “Vim” as a general term referring to any Vim-like editor (i.e. it encompasses in particular both <a href="https://www.vim.org/">Vim</a> and <a href="https://neovim.io/">Neovim</a>), unless otherwise stated.</em></p> <h2 id="my-history-of-using-vim----a-personal-account">My History of Using Vim – A Personal Account</h2> <p>When I first grappled with Linux in the mid-to-late 1990s, I was inevitably confronted with the question of which editor to use. There was a huge amount of editors to choose from, but I quickly learned that there were two editors which were mentioned much more than others, and those two editors obviously were vi and Emacs. I started playing around a little bit with Emacs, but soon I realized that it was not the right editor for me. I was looking for a tool which allowed me to edit text files, and nothing else. And Emacs definitely allows one to do <em>a lot more</em> than just editing text files.</p> <p>Now it is certainly not my intention to revive one of the most famous holy wars ever. I completely understand if people use Emacs if this is the right editor for them (or any other editor, for that matter). For me, however, vi (or rather Vim at that time) turned out to be the right editor.</p> <p>Its simplicity and minimalist appearance appealed a lot to me. I liked that the mouse played no role in using it. And I knew that there was no need for me to look any further.</p> <p>I guess I was drawn to vi for the same reasons I was – albeit many years later – drawn to the <a href="https://www.openbsd.org">OpenBSD</a> operating system: I like things to be minimal. In particular, tools should do one thing only and do it well (the core of the <a href="https://en.wikipedia.org/wiki/Unix_philosophy">Unix philosophy</a>, by the way).<sup id="fnref:1"><a href="#fn:1" class="footnote" rel="footnote" role="doc-noteref">1</a></sup></p> <p>Once I started using Vim, I never felt any desire to switch to another editor, and it is now my editor of choice since more than a quarter of a century (and I am so fond of it that I even maintain a dedicated <a href="/vi/">vi page</a>).</p> <h2 id="so-how-do-i-actually-use-vim">So, How Do I Actually Use Vim?</h2> <p>I do basically all my editing and writing in Vim, from e-mails to my PhD thesis (and, obviously, this very article as well). I also do all of my programming in Vim (no need for fancy IDEs). It is suitable for minor editing tasks just as well as for large writing or programming projects, and it has never failed me. It is fast – <em>really</em> fast –, and plain vi is available on basically every Unix installation out there – no matter what flavor of Unix or what age it is.</p> <p>I love that it is a modal editor. In contrast to most other editors, pressing a key does not automatically make the corresponding character appear on the screen – it only does if you happen to be in insert mode. Otherwise, it is interpreted as a command. This allows for pretty easy key combinations for most simple and elementary commands (in contrast to non-modal editors, where one always has to escape entering characters, which necessarily leads to more complex key combinations). I also love that commands are very logical in a specific way; one could argue that they form some sort of a language. I will not dive into the details here; that would make for an entire new article (or two or three…). It has been claimed that editing text in Vim is an almost Zen-like experience, and while I feel that this does not really do justice to Zen, I completely get what is meant by that statement.</p> <p>I do not use any plugins, although there is a huge ecosystem of plugins available for Vim (and Neovim even declares itself a “hyperextensible Vim-based text editor” on its <a href="https://neovim.io/">website</a>). I simply do not have any need for them. While there are certainly plugins which aim at improving the <em>editing</em> experience, my impression is that many plugins try to make Vim into something more than an editor. As mentioned earlier, though, that was one of the major reasons for me <em>not</em> to use Emacs. I do not want Vim to be more than an editor. I want to have an editor – no more and no less, period.</p> <p>Actually, I do not even care much about many of the <em>improvements</em> of Vim over plain vi (Vim is “Vi IMproved”, after all…). For instance, I never use visual mode. While it may be helpful when one is new to Vim<sup id="fnref:2"><a href="#fn:2" class="footnote" rel="footnote" role="doc-noteref">2</a></sup> – and in particular when one is used to GUI editors allowing one to mark text –, it is probably not the most efficient way to accomplish most of the things it is used for. In fact, I would argue that it would be a good idea to use plain vi for quite some time before (potentially) moving on to Vim. Many people probably do not even know how to accomplish things in vi without resorting to the <em>improvements</em> Vim offers. Yet, I am convinced that many of those <em>improvements</em> are improvements only in a superficial way. All this is elaborated extremely well in a reply on Stack Overflow, <a href="https://stackoverflow.com/a/1220118">Your problem with Vim is that you don’t grok vi</a>. I suggest reading it to everyone who is using Vim.</p> <p>So, in a perfect world, I would be using plain vi instead of Vim<sup id="fnref:3"><a href="#fn:3" class="footnote" rel="footnote" role="doc-noteref">3</a></sup>, and actually this is what I did for a couple of years.<sup id="fnref:4"><a href="#fn:4" class="footnote" rel="footnote" role="doc-noteref">4</a></sup> There are some reasons, though, why I switched to using Neovim for most things. One reason is that multiple levels of “undo” <em>is</em> in fact a real improvement over vi. Besides, I hail from one of those strange countries where people like to draw little dots above the letters, so Unicode support is practically non-negotiable for me. Also, I do use syntax highlighting, though I consider it by no means necessary (contrary to what I used to believe before using plain vi exclusively for a while).</p> <p>My <code>.vimrc</code> is very simple as well. While I am quite impressed by all the config files one can find on the Internet which are hundreds of lines long, and while I have a tendency myself to tweak config files way too much, I prefer to keep things simple here as well. Setting a few options fully suffices to make Vim behave the way I like.</p> <p>Now, while one might get that impression, it is certainly not my intention to argue against using Vim and in favor of vi. While I do think that Vim has become rather bloated over time, I use it on a daily basis and am most happy with it. My point is to direct the focus on the beautiful core of Vim – which is pretty close to plain vi in my opinion, yet extends it in certain ways. I sometimes like to compare vi and Vim to C and C++:<sup id="fnref:5"><a href="#fn:5" class="footnote" rel="footnote" role="doc-noteref">5</a></sup> There is this beautiful, rather small and well-defined, yet immensely powerful language C. And then there is C++, which extends C by far, adding feature over feature to it. Both are used heavily, and there are certainly reasons for both; but in most cases, I would rather use C instead of C++ (if I used them at all…).</p> <p>So, coming back to the subject of this article, the question of how I use Vim: I use it mostly the way I would use plain vi, but I also happily make use of those extensions I find useful – which are rather few, though. While I have used Vim for decades, I am sure I only employ a small fraction of the possibilities Vim – or even vi – offers. I might become more efficient by putting work into learning more subtle and intricate features, but I feel no real need for it. I know that, should I need a particular feature, I will most certainly find it – if not in vi, then in Vim. Most of the time, though, I am happy using a select set of commands in a more or less efficient way.</p> <p>There is so much more to say about Vim (maybe in the context of another Vim Carnival?), but for now, I will close my ramblings about Vim with one last observation: I do not just <em>use</em> Vim – I <em>enjoy</em> using it, a lot.</p> <h2 id="further-reading">Further Reading</h2> <p>There are a lot of great text about Vim out there (for a selection, see my <a href="/vi/">vi page</a>), so I would just like to mention two particular ones here:</p> <ul> <li><a href="https://moolenaar.net/habits.html">Seven habits of effective text editing</a> by Bram Moolenaar, author of <a href="https://www.vim.org/">Vim</a>.</li> <li><a href="http://www.viemu.com/a-why-vi-vim.html">Why, oh WHY, do those #?@! nutheads use vi?</a></li> </ul> <p>There once was another nice article called “Grokking the Zen of the Vim Wu-Wei”, but unfortunately the original link is broken, and I cannot find it anywhere else.

Therefore, the action in both cases is sending an e-mail to me reminding me of the given event. Since the e-mail needs to be sent non-interactively when the given time is reached, the <code>mail</code> utility is invoked, and the reminder text is passed to it as the mail subject (since they are usually short, I only specify a subject and leave the body empty; then I don’t even have to open the e-mail).</p> <p>In order not to have to specify the non-changing details (like the e-mail address) for sending the mail each time, I employ a small script called <code>mailrem</code> which is basically a wrapper around <code>mail</code> which takes the reminder text as its argument:</p> <pre><code>#!/bin/sh from="John Doe &lt;john.doe@email.com&gt;" subject="$1" echo | mail -r "$from" -s "$subject" "$from" </code></pre> <p>Finally, in order for <code>mail</code> to be able to send mails to a remote SMTP server, <code>smtpd</code> needs to be xref:smtpd-relay[configured such that it relays outgoing mail to a remote server].</p> <h2 id="usage">Usage</h2> <p>E-mail reminders are sent by calling <code>mailrem</code> with the specific reminder text as its argument, e.g.</p> <pre><code>$ mailrem "Prepare tax statement" </code></pre> <p>In order to schedule reminders for a specific time, <code>mailrem</code> is not invoked directly as above, but either by <code>cron</code> or by <code>at</code>, depending on whether the reminder is to be sent on a regular basis or just once.</p> <h3 id="recurring-reminders">Recurring reminders</h3> <p>Recurring reminders are scheduled by <code>cron</code> via corresponding crontab entries.

A very simple system which does its job and is easy to setup and maintain.</p> <h2 id="caveats">Caveats</h2> <ul> <li>The system is certainly not suitable for time-critical reminders. This is obvious, since by nature the reminders are sent in an asynchroneous way (i.e. via e-mail).</li> <li>There is no easy way to get a consolidated overview over all currently scheduled reminders. For recurring reminders, <code>crontab -l</code> could be used. Similarly, <code>atq</code> displays the queue of atjobs. However, the output of <code>atq</code> is pretty much unparseable (at least in the version which ships with OpenBSD). So one would have to manually extract the job ID from the output of <code>atq</code> and then do <code>$ at -c &lt;id&gt;</code> in order to see the content of the job.</li> <li>Failures cannot easily be discovered in general, and there is no recovery mechanism.

It was a static website, just like this one. I wrote the content in AsciiDoc and created a small script which rendered the pages to HTML.</p> <p>I was very proud of it.</p> <p>The content was basically plain text with a little bit of markup and some meta data – a beautifully clear separation of form and content.</p> <p>The script generating the site consisted of about 200 lines of Ruby code. It was simple, and it did its job.</p> <p>But it turned out that I would spend far more time tweaking the script to generate the site than to write content. After all, it was easier and more fun than to think about what to write.</p> <p>Also, the barrier to publish was too high: There were always a few steps to be done before any change could be published. Not many steps, really: Make some change, run the script, clone the respository for the site, delete its content, copy the output of the script to the repository, commit and publish it.</p> <p>Yet too many, as it turned out.</p> <p>So I ditched the script for generating the site and started anew.</p> <p>This time, it’s just plain HTML. Everything is created manually. Sounds like more work, but it’s not. It’s a profound simplification.</p> <p>This approach has its drawbacks, of course. The content is interspersed with markup – HTML is not really lightweight. It is not possible to make a change in the template which is immediately reflected in all pages using this template.</p> <p>But it’s definitely worth it.</p> <p>I thought my site was simple, but it wasn’t. Or at least not simple enough.</p> <p>Lesson learned.</p> <p>Pretended Intentionality</p> https://thorstenzoeller.com/pretended-intentionality 2021-10-21 2021-10-21 <h1 id="pretended-intentionality">Pretended Intentionality</h1> <p>2021-10-21</p> <p>I have recently become aware of an interesting – and somewhat concerning – behavior of mine in relation to my phone: In those spare moments when I am waiting for something, for instance, and the inevitable compulsion to check my phone arises, I often do manage to resist that urge. But after that first little victory over myself, something interesting happens: My mind, unable to accept that it is denied the diversion it so much craves, is trying to come up with suggestions for things that would be worth doing with my phone while waiting:<sup id="fnref:1"><a href="#fn:1" class="footnote" rel="footnote" role="doc-noteref">1</a></sup></p> <p><em>What was it again that makes Ridge A such a special place?

It is full of wisdom, packed even more densely with insights than Dereks’ previous writings.</p> <p>The title of the book asks one of the most important questions of life – maybe the single most important one –, and it implies that the book sets out to answer this question.</p> <p>Instead of answering the titles’ question, however, the book presents us with <em>twenty-one</em> ways how to live. Each of the 21 short chapters explains how to live a life according to a certain guiding principle. It describes how to live in complete accordance with that principle, to adhere to it with the utmost consequence.</p> <p>But: All of the 21 ways to live are completely incompatible with each other, due to their conflicting guiding principles.</p> <p>So does this book answer the question posed in its title? No. Instead, it presents possibilities. Every single chapter is convincing and persuading, yet every one is completely different than any other.</p> <p>To me, the core statement of this book is that there are no definite answers, at least not to the really important questions of life. We humans yearn for answers, for recipes, for certainty – yet at some point, everybody has to face the fact that there are no simple, universal answers to the truly important questions. Life is contradictory, often messy, rarely proceeding along a straight line. And, most important: Each life is absolutely individual, and everyone has to find his own answers.</p> <p>Just as remarkable as the books’ content is its form. It is incredibly dense. Derek somehow manages to picture the different ways to live in often not more than three or four pages. Most sentences are very short, often fitting on a single line, and new sentences always start on the next line. His writing is never pleasing, but always sharp and to the point, and with “How to Live” he has perfected his style. To me, it is supremely elegant.</p> <p>Two quotes come to my mind when thinking of “How to Live”:</p> <p>“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” by Antoine de Saint-Exupéry. It seems to me that this was Dereks’ personal guiding principle in writing this book.</p> <p>The second one is by Michelangelo: “The sculpture is already complete within the marble block, before I start my work. It is already there, I just have to chisel away the superfluous material.” I can imagine how Derek spent hours and hours chiseling away the superfluous words, finally achieving something which comes very close to the perfection as it is defined in the quote by Antoine de Saint-Exupéry above.</p> <p>Making a point using many words is easy; making a point using very few words is exceedingly difficult. Derek has succeeded in every aspect.</p> <p>If you have not read the book yet, buy it and read it, immediately. Then, after some time, read it again, and again.</p> <p>Derek Sivers: “Useful Not True”</p> https://thorstenzoeller.com/sivers-useful-not-true 2025-07-06 2025-07-06 <h1 id="derek-sivers-useful-not-true">Derek Sivers: “Useful Not True”</h1> <p>2025-07-06</p> <p><a href="https://sive.rs/u">Useful Not True</a> is another gem by Derek Sivers. Whenever he publishes a new book, I order it immediately, no matter what it is about. I know from experience that everything he writes is packed with wisdom and insights I don’t want to miss.</p> <p>Let me start with the form of the book (I am referring to its physical version here): It is short, as Derek’s books usually are. Most chapters are one or two pages at most, very few are longer. The font size is pretty large, as well as the distance between lines, and the lines are rather narrow, which makes the reading a very pleasant experience. This is in contrast to many other books which look as if they were laid out with the goal to pack as many words as possible on each page. With Derek’s books, it is the exact opposite, with respect to both form and content: They look as if the goal was to use as <em>few</em> words as possible (and it was!). They are a perfect example for James Altuchers’ maxim “<del>To</del> increase the value of <del>your</del> words, make them <del>as</del> few <del>as possible</del>.”</p> <p>The content of the book perfectly matches its form: It is distilled to the bare minimum of what is necessary to convey its point. Nothing is superfluous; every word serves a purpose. One could certainly easily inflate the books’ content to 1000 pages, but it would not be possible to reduce it to fewer pages without losing content.</p> <p><em>Useful Not True</em> is a book about perspective. Everything is relative; nothing is absolute. There is no “right” or “wrong”, just “useful” or “useless”. While reading it, so many associations popped up in my mind:</p> <p>To Zen Buddhism with its belief that everything is made up by the mind alone and its seeking for looking at things as how they are, without making up things about them in our mind.</p> <p>To phenomenology and its concept of <em>epoché</em> (and similar concepts in Stoicism and other philosophies), a method for refraining from subjective judgements of things or situations.</p> <p>And even to physics and mathematics, in different aspects: In gauge theories, there are intrinsic unphysical degrees of freedom. By fixing the gauge, those unphysical degrees of freedom can be removed. And this can be done in different ways, depending on what is most useful in the respective situation.</p> <p>Also, physical theories are formulated as models which describe (physical) reality. They never do it perfectly, though, because they cannot capture every aspect of reality. And yet, good models are extremely useful (and a good model is not necessarily one that describes reality most accurately; it may be perfectly sufficient to describe a very particular aspect of reality with a certain coarseness if it still captures the relevant physical mechanisms). As George E. P. Box put it: “Essentially, all models are wrong, but some are useful.”</p> <p>The importance of the book lies in the fact that, while its statement seems perfectly plausible, we very often tend to ignore it. Ask two people standing opposite each other where the river is. The one says: “On the left.” The other says: “On the right.” Who is right? It is remarkable how firm our belief is that there is “right” and “wrong”, while it is so obvious that this is usually not true, if we just looked at things as they are. While the consequences may be trivial as in the example above, they can be arbitrarily grave in other situations.</p> <p>So, on the one hand, recognizing there are no absolutes can prevent us from making mistakes in judging situations. But there is another aspect, which is hinted at in the title of the book: We can turn this realization to our advantage. You can face a wall, or you can turn around and look at a serene beach. Both perspectives are “right” or valid. Why not choose the one you like better? There lies power in not being confronted with the one “true” perspective, but instead being able to choose ones preferred perspective, and this power can be harnessed – provided we know that we can simply turn around.</p> <p>I will end with my usual recommendation of Derek’s books: Buy it, read it, and digest its content as fully as possible!

This will highlight the word, and it is then in the primary selection of the X Window System and can be pasted elsewhere.</p> <p>Characters are grouped into <em>character classes</em>. Words are defined in <code>xterm</code> as strings of characters belonging to the same character class. Therefore, what <code>xterm</code> interprets as a word depends on the mapping of characters to character classes.</p> <p>In the default mapping, alphanumeric characters and the underscore belong to one character class, space and tab belong to another character class, and all other characters have their own character class. This definition works well when dealing mostly with prosaic texts, since it more or less corresponds to the usual definition of a word (i.e. certain characters separated by whitespace). In other cases, it is less convenient though. For instance, it is not possible to select a path consisting of several directories by double-clicking on it, since directories are separated by a slash, which belongs to a different character class than alphanumeric characters and the underscore.</p> <p>Interestingly, the mapping can be changed via a certain <code>xterm</code> resource called <code>charClass</code>. Its value is a list of key-value pairs, where the key is either a single character code or a range of character codes, and the value is a character class. A given key-value pair then defines that the character(s) specified by the key belong to the character class specified by the value.</p> <p>Character classes are identified by numbers (which in turn correspond to the character code of a representative of that character class). The default mapping of characters to character classes is given in the <a href="https://man.openbsd.org/xterm.1#CHARACTER_CLASSES">respective section of the manpage</a>. In the default mapping, alphanumeric characters and the underscore belong to character class 48 (the character code of the character <code>0</code>), and space and tab belong to character class 32 (the character class of <code>space</code>).</p> <p>Therefore, in order to add e.g. the characters <code>!</code> (character code 33) and <code>:</code> (character code 58) to character class 48, add the following line to <code>~/.Xresources</code>:</p> <pre><code>xterm*charClass: 33:48,58:48 </code></pre> <p>To add all “regular” characters to character class 48, add the following line to <code>~/.Xresources</code>:</p> <pre><code>xterm*charClass: 33-126:48 </code></pre> <p>Activate the change:</p> <pre><code>$ xrdb -merge ~/.Xresources </code></pre> <h2 id="xterm-knows-more-than-just-words">xterm Knows More Than Just Words</h2> <p>Words are just one kind of character grouping in <code>xterm</code>. The full list is:</p> <dl> <dt><code>word</code></dt> <dd>As defined above.</dd> <dt><code>line</code></dt> <dd>The entire line to which the character under the pointer belongs to.</dd> <dt><code>group</code></dt> <dd>Basically the paragraph the character under the pointer belongs to, i.e. all lines above and below up to the next blank line. Does not extend outside the current page.</dd> <dt><code>page</code></dt> <dd>All visible lines on the current page.</dd> <dt><code>all</code></dt> <dd>All lines, including i.e. saved lines.</dd> </dl> <p>Even that is not all there is, though. On top of that, it is even possible to define custom groupings via regular expressions (basically, all other predefined groupings are just shortcuts; they could just as well be defined via a corresponding regular expression). Also, there is the pseudo-grouping <code>none</code> which specifies that no selection should occur in the respective case.</p> <p>So it is possible to specify in a very fine-grained way what will be in the primary selection when double-clicking on some character. But it can be specified just as well what happens when clicking multiple (i.e. more than two) times in rapid succession. This is useful since one may be interested in selecting different character groupings depending on the respective case. For instance, in the default configuration, triple-clicking usually selects the entire line. Which character grouping is selected when clicking 2, 3, 4 and 5 times in rapid succession is specified by assigning one of the character groupings defined above to the <code>xterm</code> resources <code>on2Clicks</code>, <code>on3Clicks</code>, <code>on4Clicks</code> and <code>on5Clicks</code>, respectively.</p> <p>As an example, in order to specify that double-clicking should select words defined as a string consisting of alphanumeric characters, the underscore, the exclamation mark and the colon, that triple-clicking should select words defined as a string consisting of all regular characters except whitespace (defined via a corresponding regular expression), and that clicking four times in rapid succession should select the entire line, add the following lines to <code>~/.Xresources</code>:</p> <pre><code>xterm*charClass: 33:48,58:48 xterm*on2Clicks: word xterm*on3Clicks: regex [^[:space:]]+ xterm*on4Clicks: line </code></pre> <p>Even when using the mouse sparingly, it is very convenient to be able to specify what gets selected on multiple clicks in <code>xterm</code>, and it certainly does save some time.</p> [Stream] 2021-05-01 https://thorstenzoeller.com/stream/#_2021_05_01_1 2021-05-01 2021-05-01 <p><a href="https://www.openbsd.org/69.html">OpenBSD</a> released – the 50th OpenBSD release!</p> [Stream] 2021-05-02 https://thorstenzoeller.com/stream/#_2021_05_02_1 2021-05-02 2021-05-02 <p>Switched from Vim to nvi.

Actually, it mostly references a recent interview with him, citing some passages from it and featuring his comments to them. In particular, he further stresses the importance of boredom in his remarks.</p> <p>Boredom is an issue I also find highly interesting, and I am convinced – as Craig is – that it is really important to experience boredom and to be able to stand it and cope with it, and that we currently live in an age where we are trying very hard to do everything we can to not be bored, mostly by resorting to various kinds of ever more intricate and sophisticated (and not so sophisticated) distractions and diversions.</p> [Stream] 2022-03-26 https://thorstenzoeller.com/stream/#_2022_03_26_1 2022-03-26 2022-03-26 <p><a href="https://www.nytimes.com/2018/02/16/opinion/sunday/tyranny-convenience.html">The Tyranny of Convenience</a> by <a href="http://www.timwu.org/">Tim Wu</a> – an important article to which I was pointed by the article <a href="https://seths.blog/2022/01/harder-easier-and-more-convenient/">Harder, easier and more convenient</a> by Seth Godin. Both articles emphasize the importance of doing things which are <em>not</em> convenient, in the face of the general trend towards ever more convenience in practically all areas of life. The last paragraph of Tim Wu’s article provides a good summary:</p> <blockquote> <p>So let’s reflect on the tyranny of convenience, try more often to resist its stupefying power, and see what happens. We must never forget the joy of doing something slow and something difficult, the satisfaction of not doing what is easiest. The constellation of inconvenient choices may be all that stands between us and a life of total, efficient conformity.</p> </blockquote> [Stream] 2022-03-27 https://thorstenzoeller.com/stream/#_2022_03_27_1 2022-03-27 2022-03-27 <p>Just rediscovered this impressive depiction of depths: <a href="https://xkcd.com/1040/">xkcd: Lakes and Oceans</a>.</p> [Stream] 2022-04-02 https://thorstenzoeller.com/stream/#_2022_04_02_1 2022-04-02 2022-04-02 <p><a href="https://www.nature.com/articles/d41586-022-00453-4">Turning off my phone improved my science</a> – insightful article by PhD student Adam Weiss.

While tensors are at the foundation of much of the mathematics of physics today, they are still not usually being introduced and taught as the geometrical objects they are. Sure, when working in a space which is endowed with sufficient structure, many objects can be transformed to either vectors or scalars, but that completely conceals their true geometrical nature.</p> <p>It is really remarkable (in a sad way) that the focus of teaching today is so much on what is likely considered to be some kind of pragmatism or practicality. This may make it easier to quickly get enabled to calculate stuff, but this ease comes at the expense of developing a real understanding. I think this is a very shortsighted approach.</p> <p>Furthermore, and just as important in my opinion, students are deprived of experiencing the full beauty of these objects in favor of providing them with a mere tool whose sole purpose it is to be able to somehow obtain correct results (not that this is not important, but it is only one aspect).</p> <p>So what to do about this? For beginning undergraduate students, I recommend reading <em>Geometrical Vectors</em> by Gabriel Weinreich (which basically contains no formulae at all and instead completely focuses on conveying a grasp of the objects themselves). When I first read <em>Geometrical Vectors</em> sometime during my undergraduate studies, it did not speak to me at all (I guess I was already too much indoctrinated by the traditional, orthodox way of teaching vectors and tensors). The second time I read it, however, was a profound experience, almost like an epiphany.</p> <p>After having developed a basic understanding of these matters, <em>Gauge fields, knots and gravity</em> by John Baez and Javier P. Muniain is a great resource (it contains much more and advanced material though). <a href="https://math.ucr.edu/home/baez/">John Baez</a> is a master of conveying physical and mathematical ideas, and I would recommend basically everything he writes.</p> <p>Read on <a href="https://exquisite.social/@thorstenzoeller/112745177106216414">Mastodon</a>.</p> [Stream] 2024-07-12 https://thorstenzoeller.com/stream/#_2024_07_12_1 2024-07-12 2024-07-12 <blockquote> <p>Human beings used to witness<br /> 25,000 sunrises during their lifetime.<br /> Have you seen 25 in the last year?<br /> Or were you too busy?</p> <p>– The Minimalists, <a href="https://www.theminimalists.com/unbusy/">Unbusy</a></p> </blockquote> <p>Read on <a href="https://exquisite.social/@thorstenzoeller/112773291187369088">Mastodon</a>.</p> [Stream] 2024-07-14 (1/2) https://thorstenzoeller.com/stream/#_2024_07_14_1 2024-07-14 2024-07-14 <p><a href="https://medium.com/the-art-of-software-development/why-functional-programming-matters-63e92ac959ca">Why Functional Programming Matters</a> by Minh Quang Tran.</p> <p>Read on <a href="https://exquisite.social/@thorstenzoeller/112786034522255176">Mastodon</a>.</p> [Stream] 2024-07-14 (2/2) https://thorstenzoeller.com/stream/#_2024_07_14_2 2024-07-14 2024-07-14 <p>Finished reading <em>Der Zen-Affe und die Lotusblume</em> (<em>The Zen Monkey and the Lotus Flower</em>).

But while man was not able to sit quietly in a room alone already several hundred years ago, in our times it has become incomparably harder – knowing that the much sought-after distraction – and thereby salvation – from his aloneness is not waiting somewhere outside his empty room, but beckoning right next to his fingertips.</p> <p>Read on <a href="https://exquisite.social/@thorstenzoeller/114145031336183336">Mastodon</a>.</p> [Stream] 2025-03-13 https://thorstenzoeller.com/stream/#_2025_03_13_1 2025-03-13 2025-03-13 <p>Finished reading <em>A System for Writing</em> by <a href="https://bobdoto.computer/">Bob Doto</a> (yes, I’m a very slow reader…).

It is a typesetting system for creating documents which has a lot of features, including advanced facilities for typesetting mathematical formulae. I have only started diving into it, but it looks <em>really</em> promising, and as far as I can tell so far, it may even have the potential to replace LaTeX (though it is probably a little early to assess).</p> <p>Currently, I use <a href="https://docs.asciidoctor.org/pdf-converter/latest/">Asciidoctor PDF</a> for simpler documents and LaTeX for more complex documents, in particular documents involving mathematical formulae (though this happens rarely these days). <em>Typst</em> might very well be able to satisfy both these use cases. And there is even an OpenBSD package for it!</p> [Stream] 2025-10-01 https://thorstenzoeller.com/stream/#_2025_10_01_1 2025-10-01 2025-10-01 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Hunter’s Moon”)</a>:</p> <blockquote> <p>hunter’s moon shining<br /> brightly over reddish woods –<br /> autumn time has come</p> </blockquote> [Stream] 2025-10-02 https://thorstenzoeller.com/stream/#_2025_10_02_1 2025-10-02 2025-10-02 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Grain”)</a>:</p> <blockquote> <p>heaps of grain filling<br /> the storage chambers, a mouse<br /> delights in its share</p> </blockquote> [Stream] 2025-10-03 https://thorstenzoeller.com/stream/#_2025_10_03_1 2025-10-03 2025-10-03 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Frost”)</a>:</p> <blockquote> <p>frost-covered meadows<br /> let fall in oblivion<br /> a summer long gone</p> </blockquote> [Stream] 2025-10-04 https://thorstenzoeller.com/stream/#_2025_10_04_1 2025-10-04 2025-10-04 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Yellow Leaves”)</a>:</p> <blockquote> <p>yellow leaves dancing<br /> wildly in the air, stirred up<br /> by harsh autumn wind</p> </blockquote> [Stream] 2025-10-05 https://thorstenzoeller.com/stream/#_2025_10_05_1 2025-10-05 2025-10-05 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Flour”)</a>:</p> <blockquote> <p>no trace of the mouse –<br /> except footsteps in the flour<br /> scattered on the floor</p> </blockquote> [Stream] 2025-10-06 (1/2) https://thorstenzoeller.com/stream/#_2025_10_06_1 2025-10-06 2025-10-06 <p><a href="https://mastodon.world/@dailyhaikuprompt">Daily haiku (prompt “Night Chill”)</a>:</p> <blockquote> <p>as the moon rises<br /> on a starry sky, autumn’s<br /> night chill slowly spreads</p> </blockquote> [Stream] 2025-10-06 (2/2) https://thorstenzoeller.com/stream/#_2025_10_06_2 2025-10-06 2025-10-06 <p>Thanks to <a href="https://adam.omg.lol/">Adam Newbold</a>, today I learned that one’s <a href="https://social.lol/@adam/115328017911416358">Mastodon posts are automatically published via an RSS feed</a>, where the URL of the feed is obtained by simply appending <code>.rss</code> to the URL of one’s Masotodon account (so, for instance, my feed is available under <a href="https://exquisite.social/@thorstenzoeller.rss">https://exquisite.social/@thorstenzoeller.rss</a>) – <a href="https://sive.rs/obvious">Obvious to others.
