Read more |Programming projects in 2021
It has again become time to summarize the top FOSS projects I've been involved with during the past year. Not all projects I worked on are listed; I've tried to limit it to the ones where I spent the largest amount of time, or where I consider the project/work done to be particularly interesting for one reason or another.
Read more |The dangers of referential equality in Java
In this post I'll write about referential equality (ie the == operator) and why it can be very dangerous to use this operator incorrectly in Java. I made this mistake today, and it is my hope that this blog post will help you to avoid doing the same mistake yourself (or at least get a good laugh). 
Saying goodbye to an old friend: Decommissioning a Raspberry Pi web server

Read more |Java for C# programmers
In this post I'll write about a number of differences between Java and C# that I've experienced at my current job. First a bit of a background: Before I switched jobs in August 2018, I had been working with C#, Ruby and other programming languages for the last 15 years; Java was pretty much out of the picture for me.

Read more |GDB tracepoints
Many of us have been using GNU GDB for debugging to some extent, but at least for me personally, I know that there is a lot more to learn about how to use it effectively. In this blog post I go through something I call tracepoints and why they can be invaluable in debugging complex problems.
Read more |Linux kernel compilation as a benchmark tool
Back in the days, compiling the Linux kernel was a rough (but still remotely useful) measure of the performance of a machine. How long does it take to compile a modern Linux kernel on a modern piece of hardware? Let's find out!
