      While I don’t need it (and thus don’t buy it): the PineTab is a pretty interesting device.

      I’m hurt again. A torn muscle fiber. At least 4 weeks no running 😭💩

      I’m seriously considering to switch again to a different distribution. Maybe back to Arch or something like that.

      I get why Canonical hypes Snaps that much. But seriously, why do they have to be so fucking slow to start? A simple application I already use for ages, Hexchat, now takes more than 20 seconds to start. It feels like being back on spinning disks again, and worse, even slower.

      „Die Zerstörung der Presse“ – Ich finde den Stil zwar anstrengend (bin vermutlich einfach zu alt), aber er hat Recht. Viele Kritik-Punkte gehen mir auch schon seit Jahren gegen den Strich. Danke, Rezo.

      Meh. Had to skip training today because of a pulled right adductor

      Today’s training: 2km warm-up, six 1500m intervals at 03:45 min/km and 400m rest at 04:30-05:00 min/km, 4km cool down. Purpose of this training: practise to metabolize lactate.

      I love these long intervals 😍

      Call me immature, but I actually enjoy Shera. I just started watching season 5.

      Oh, the Microformats2 parsing specification has been updated. Guess I have something to do for the next few evenings.

      I’ve been running 78km this week. After my injury last year I never thought I would get this far again. I’m more than satisfied with this progress 😁 while I can’t run the competitions I was planning to run I aim for a 3 hours marathon next year (I just assume that running competitions are possible next year again).

      I just love running. 💖

      Seems like the bathing season has begun… I walked along a local bathing lake on during the dog walk. There were at least 20 cars parking. That‘s ridiculous… global pandemic my ass.

      I have to admit: I’m bored. Due to the „stay at home“ policy and most of the things being closed I need a new side project. Something which gives me the opportunity to learn Rust would be nice. Has anybody a good idea?

      Note to myself: UPDATE tbl SET foo = fun(id) in a trigger is a bad idea 😜

      TIL: in Emacs you can persist the helm-rg result list with M-b. This opens a persistent buffer with the list of search results.

      Too many people have joined the chorus of cacophonous conversations online about booting Richard Stallman from the free software movement. They claim that his social behavior has prevented more people from joining. There are conspiracy theories claiming a hit job by an evil corp. The point that everybody misses is that Stallman’s views on software don’t matter anymore.

      A very interesting article about how the views of the FSF and Stallman completely ignore the essential problems in IT and society in current day and age.

      Whoever thought it would be a good idea to use email as a second factor should be punished. And whoever thought it would be a good idea to use email as a second factor and let the code be only valid for five minutes should be punished even more.

      Whether you’re coming to Haskell from another language, or if you’re interested in writing programs that, y’know, actually do things, participating in the Haskell community can feel like you’re a second class citizen. […] If you’ve already learned another language, you can learn Haskell. And even if you haven’t, learning Haskell is no harder than learning any other programming language.

      My experience when learning Haskell was that it is a really hard language to learn. A lot of very foreign concepts with a lot of foreign words.

      But in hindsight it wasn’t that hard; the documentation I tried to learn with was just not very good.

      Today I learned: you can specify a binding position in an Ecto query via parameter:

      def apply_some_filter(query, binding_position, field_name) do
        from([{rel, binding_position}] in query, where: field(rel, ^field_name) == "foo")

      This works thanks to pattern matching 😍

      I’m glad I used Ansible for deploying my servers a few years ago. This allowed me to move my current setup to a new Digital Ocean droplet with minimal effort. Just a few changes due to new system versions. 🎉

      It’s fascinating to see how Rammstein still manages to create controversy and attention, even though they are in the business that long. First there „Deutschland“ video, where a lot of mainstream media weren’t able to see the criticism on German history and called fascism. And now „Radio,“ a homage to the German band „Kraftwerk,“ a nostalgic view back on DDR history and, again, criticism on German history. And again all media is reporting.

      Well done, Rammstein! 👍

      Public service announcement: Math.max(...[]) returns -Infinity - took me about an hour of debugging to locate this problem.

      Currently I am working on a TypeScript project. During this project I wanted to give the TypeScript compiler the hint that I expect a class object as a parameter. I couldn’t find something in the documentation. But since you can use expressions as type declaration I tried to use typeof:

      class Bar {}
      function foo(val: typeof Bar) {}

      Surprisingly this works. Now after I knew what I had to look for I could find a hint in the documentation as well:

      Next, we then use the class directly. Here we create a new variable called greeterMaker. This variable will hold the class itself, or said another way its constructor function. Here we use typeof Greeter, that is “give me the type of the Greeter class itself” rather than the instance type.

      Maybe this saves you a few headaches.

      EmacsCast: A journey into Emacs is a podcast of a programmer diving into Emacs. While I didn’t listen to it, yet, I thought I should share it because there is not very much Emacs content out there. In the first episode he introduces hilself and explains why he, as a SublimeText user, dives into Emacs.

      After a pause of 14 days it is surprisingly easy to get back into running. 17,8km in 01:21:33, 04:35 per km 🏃
