Recently I came across a delightful article on idiomatic Ruby. I’m not a good Ruby developer by any means, but I realized, that a lot of the patterns are also quite common in Rust. What follows is a side-by-side comparison of idiomatic code in both languages. The Ruby code samples are from the origi… More »
In December 2015 I was looking for static analysis tools to integrate into trivago's CI process. The idea was to detect typical programming mistakes automatically. That's quite a common thing, and there are lots of helpful tools out there which fit the bill. So I looked for a list of tools... More »
October is the perfect time to contribute to Open Source — at least according to Github and DigitalOcean. Because that's when they organize Hacktoberfest, a global event where you get a free shirt and lots of street cred for creating pull requests. More »
What’s the simplest Unix command you know? There’s echo, which prints a string to stdout and true, which always terminates with an exit code of 0. Among the series of simple Unix commands, there’s also yes. If you execute it without arguments, you get an infinite stream of y’s, separated by a newlin… More »
My website is reasonably fast. There was one thing left which really annoyed me: layout reflow after images got loaded. The problem is, that the image dimensions are not known when the text is ready to be displayed. As a result, the text will be pushed down on the screen as soon as an image is loaded above. I decided to fix that once and for all. More »
Rust or Go, which one should I choose? is a question I get quite often. Both languages seem to be competing for the same user base and they both seem to be *systems programming* languages, so there must be a clear winner, right? More »
In the last few years, I've had the pleasure to work with a lot of talented Software Engineers. More »
Recently, I tried to implement a binary tree data structure in Rust. Each binary tree has a root value, a left, and a right subtree. I started from this Python implementation, which is quite straightforward. More »
I’ve written most of my code in dynamically typed languages such as Python or PHP. But ever since dabbling with Rust, I’ve developed a passion for static type systems. It began to feel very natural to me; like a totally new way to express myself. More »
When I was around 12, I set myself the goal to become a professional programmer. I can tell, because at this time I made the conscious decision to use my right hand to control the mouse — even though I’m left-handed. My reasoning was, that if I ever had to help out a colleague with a computer proble… More »
