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")
endThis 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. 🎉
Stop Scrolling Facebook! A pretty nice talk by Tantek Çelik about taking back the web.
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! 👍
regexpu is a nice little tool to transpile ES6 unicode regular expressions to ES5 👍
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) {}
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!
From What I have learned working 1 year full-time using Elixir:
I do not get why don’t we all just write Erlang programs. You can write them, walk away for 20 years and they will be still up and running. Pure joy.
I can relate 😁
Mein Freund Marc veranstaltet am 19.09.2018 eine Schulung Meine Barrierefreie Website in Köln. Wenn ihr in der Gegend seit: das ist etwas, das sich durchaus lohnt. Der Marc weiß, wovon er spricht.
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 🏃
The day starts bad with bad milk in my coffee. Buärghs.
This is the reason why I use org-mode. If I imagine that I would get locked in like that with my notes I get the creeps…

Just thought the same this week 🤔 Will try to do that, too… especially blogging should have a revival.
It’s one of those days where I want to throw away ten years old code and just rewrite it…
Avengers: Infinity War ★★★★★
Quick tip: use gsettings set org.gnome.desktop.interface show-battery-percentage true to show the battery percentage.
Todays goal: clipping the rest of the hedges
Elixir: Do you have HTTP Requests? You are doing them wrong! is, despite the clickbaity title, a nice comparison of HTTP libraries in Elixir. Good read!
Go: the Good, the Bad and the Ugly is an interesting article about the pros and cons about the Go programming language.
Fuck yeah! Just hit 100kg deadlift 🏋️♀️
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.
Current status: BEAMing due to working with Erlang and Elixir (get it? Get it? BEAMing!)

I’m actually so jealous. I definitely want to attend FOSDEM again
Color Safe - accessible web color combinations. What a great service.
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. 👍
A project I was working on the last couple of months finally hit production 😍
I love that feeling when the muscles begin to burn…
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.
How to pattern match on regular expressions in Elixir: %Regex{} = ~r/pattern/
Achievement unlocked: body weight (80kg) deep squat 🏋️✌️
OH: „Coffee so black it has an event horizon”
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…
Deadlift went up to 90kg at 3x12 (up from 60kg)
With 3500kcal a day I finally make some progress in weight lifting 😍 increased squats to 120kg at 3x12 this week
I hit a new running PR: a pace of 04:20 per km on a distance of 7.5km ✌️🎉

You went to Japan for the food, why am I not surprised? 😂
The second day after a workout is always the worst 💪
I noticed a new behavior. I lost 37kg in 6 months, and now, as I have finished losing weight, every time I eat above my calories I feel guilty. Yesterday I ate about 50 kcal over my need for that day, and I thought about an hour if I should go for another walk just to get rid of that surplus.
Although my goal is to gain some muscle weight (which means I have to have a caloric surplus) I am still in that „eat less!“ mindset. That’s an interesting new behavior for me.
OH: „sweat is fat crying“ 😂
I ordered the Apple Watch Series 3. While it is a lot of money for a silly watch (the most I spent on watches before the Apple Watch was about 80€ for a G-Shock) I noticed that my Series 0 watch is my most used Apple device over the last three years. I use it every day, mainly for activity tracking during sports and for calorie counting. The fitness marketing totally worked on me. I’m even excited for the new device 😝
Apple is using some interesting tech for web pages on the iPhone X (via @ttepasse).
