Anyone who spends a lot of time in the console knows the classics: cat for quickly viewing files and git diff for checking code changes. Both have served their purpose for decades, but visually they remain stuck in the past. Yesterday, I discovered two modern CLI tools and immediately installed them on my system to replace these classics: bat and delta.

Both tools are written in Rust, extremely performant, and elevate the rendering of code to a whole new level. Here is my tool presentation and how I have seamlessly integrated them into my Zsh and Git configurations.

To be honest, it’s just getting on my nerves: it has become an absolute matter of course that at the beginning of every conference call, there’s a five-minute wait to see if any more people deign to dial in.

I couldn’t help but think of a quote by Horst Lichter (from the German talk show Riverboat) that hits the nail on the head:

“You have irretrievably stolen 20 minutes from my finite life that I could not spend in a self-determined way. That really stuck with me for the rest of my life, so that no matter when, no matter where, I’m always early, because I can determine my own time, but I don’t want to steal other people’s.”

In this post, I take a look at the collected data from my weather station. I have cleaned the CSV exports and transferred them into a SQLite database to create comparative statistics and charts.

It is amazing what you can see when you look at the data over several years (2022 to present). We are again a bit nerdy on the terminal, using Python and Matplotlib for the visualization.

The Chemnitzer Linux-Tage 2026 have come to a close, and it was once again a fantastic weekend of learning, sharing, and community.

In this post, I want to look back at my experiences and highlights of the event.

Start of heading level 2: ## Friday, March 27th End of heading.

My journey to this year’s Linux-Tage began on Friday afternoon. I set off from Grimma at exactly 3:00 PM. The drive took me along country roads via Colditz, Geithain, and Narsdorf before finally hitting the A72 motorway toward Chemnitz.

If you spend a lot of time at barcamps, hackathons, or amateur radio meetings, you know the problem: Am I allowed to post this photo? Who is that in the background? And how do I signal myself what should happen with pictures of me?

This is exactly where Offlinetags come in. They are a social signal for humans – and at the same time, machine-readable markers for algorithms. Since I submitted a Pull Request today to expand the set to 6 symbols, here is the guide for all photographers and tag-wearers (including the new proposals).
