This August, I accomplished what I wanted for many years: I deleted the last cgo dependency in Debian Code Search!

For many years, I sometimes discovered that commands I was sure I had run were no longer present in my Z shell history file (~/.zsh_history).

Back in January 2025, multiple different security researchers published a total of 6 security vulnerabilities in rsync, some of which allow arbitrary code execution and file leaks, so naturally I was wondering whether/how my gokrazy/rsync implementation w…

Recently, during a production incident response, I guessed the root cause of an outage correctly within less than an hour (cool!)

I have come to appreciate coding agents to be valuable tools for working with computer program code in any capacity, such as learning about any program’s architecture, diagnosing bugs or developing proofs of concept.

Wayland is the successor to the X server (X11, Xorg) to implement the graphics stack on Linux.

For every cloud service I use, I want to have a local copy of my data for backup purposes and independence.

I have been using a MacBook Pro M4 as my portable computer for the last half a year and wanted to share a few short impressions.

I liked the NixOS meetup earlier this year, and at the end of the meetup they told everyone about NixCon 2025, which would be happening in Switzerland this year, at the very same location, the University Of Applied Sciences OST in Rapperswil, so I decided…

The Intel 285K CPU in my high-end 2025 Linux PC died again!

Passwords and secrets like cryptographic key files are everywhere in computing.

I wanted to use GoCV for one of my projects (to find and extract paper documents from within a larger scan), without permanently having OpenCV on my system.

In this article, I want to show how to migrate an existing Linux server to NixOS — in my case the CoreOS/Flatcar Linux installation on my Network Attached Storage (NAS) PC.

For one of my network storage PC builds, I was looking for an alternative to Flatcar Container Linux and tried out NixOS again (after an almost 10 year break).

Update (2025-09-07): The replacement CPU also died and I have given up on Intel.
