    • Christian Kruse,

      A repost of https://williamyaoh.com/posts/2019-10-05-you-are-already-smart-enough.html

      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.

    • Christian Kruse,

      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")
end

      This works thanks to pattern matching 😍

      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.

    • Christian Kruse,

      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) {}
foo(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.

      Over the weekend my good friend Jeena was visiting me. We had a lot of fun and tons of interesting talks. It was a pleasure, Jeena!

      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.

      Enjoy!

      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 🏃

      Quick tip: use gsettings set org.gnome.desktop.interface show-battery-percentage true to show the battery percentage.

      I hate running in the winter. The first 15 minutes it‘s fucking cold. Then up until about 10km its warm enough. Then for the rest of the run it is cold again. ❄️

      I have started to work with React during the last few months. I have to say, I am really impressed how well everything works and how easy it is to create good, working UIs with it.

      I understand now why so many users hate Windows 10… doing some support for relatives, fuck, this is unbearable. Windows seems to get worse every release.

      Resume for 2017: I ran about 1000km, lost 38kg, gained some muscles and had a lot of fun while trying to achieve this. A good year. 👍

      Wow. According to this about 50% of the top 500 websites take up to 14 seconds to „get interactive” with 4s alone spend for parsing and compiling JS. That’s insane.

      It’s ridiculous that we are not able to make a disruption free phone call on a train in 2017. Call gets cancelled every few km…
