Why Type Systems Matter

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 »

Being a Professional Programmer

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 »

The Future of Rust

Let me first point out the obvious: yes, the title is a little sensationalist. Also you might be asking why I should be entitled to talk about the future of Rust. After all, I'm neither part of the Rust core team, nor a major contributor to the Rust ecosystem. To that I answer: why not? It's fun to … More »

Are you a Programmer?

My geography teacher once told the story of her first lecture at University. As an introduction, her professor asked the class to draw a map of Germany without any help and as accurate as possible.

Overkill – Java as a First Programming Language

I recently talked to a student in my neighborhood about his first programming experiences. They started learning Java at school, and it soon turned out to be horrible. A lot of us learned to code in languages like BASIC or Pascal. There was no object orientation, no sophisticated file I/O and almost… More »
