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. Depending on the use-case, reviewing each command the agent wants to run can get tedious and time-consuming very quickly. To safely run a coding agent without review, I wanted a Virtual Machine (VM) solution where the agent has no access to my personal files and where it’s no big de...

Wayland is the successor to the X server (X11, Xorg) to implement the graphics stack on Linux. The Wayland project was actually started in 2008, a year before I created the i3 tiling window manager for X11 in 2009 — but for the last 18 years (!), Wayland was never usable on my computers. I don’t want to be stuck on deprecated software, so I try to start using Wayland each year, and this articles outlines what keeps me from migrating to Wayland in 2026. Historical context For the first few years,...

For every cloud service I use, I want to have a local copy of my data for backup purposes and independence. Unfortunately, the gphotos-sync tool stopped working in March 2025 when Google restricted the OAuth scopes, so I needed an alternative for my existing Google Photos setup. In this post, I describe how I have set up Immich , a self-hostable photo manager. Here is the end result: a few (live) photos from NixCon 2025 : Step 1. Hardware I am running Immich on my Ryzen 7 Mini PC (ASRock DeskMin...

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. As always, I am not a professional laptop reviewer, so in this article you won’t find benchmarks, just subjective thoughts! Back in 2021, I wrote about the MacBook Air M1 , which was the first computer I used that contained Apple’s own ARM-based CPU. Having a silent laptop with long battery life was a game-changer, so I wanted to keep those properties. When the US gove...

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 to go! In this trip report, I want to give you a rough impression of how I experienced this awesome conference :) The bee in the title is a NixCon inside joke ;) Friday I arrived at about 09:30 on a rainy Friday morning, meaning I hurried from ...

The Intel 285K CPU in my high-end 2025 Linux PC died again ! 😡 Notably, this was the replacement CPU for the original 285K that died in March , and after reading through the reviews of Intel CPUs on my electronics store of choice, many of which (!) mention CPU replacements, I am getting the impression that Intel’s current CPUs just are not stable 😞. Therefore, I am giving up on Intel for the coming years and have bought an AMD Ryzen 9950X3D CPU instead. What happened? Or: the batch job of deat...

Passwords and secrets like cryptographic key files are everywhere in computing. When configuring a Linux system, sooner or later you will need to put a password somewhere — for example, when I migrated my existing Linux Network Storage (NAS) setup to NixOS , I needed to specify the desired Samba passwords in my NixOS config (or manage them manually, outside of NixOS). For personal computers, this is fine, but if the goal is to share system configurations (for example in a Git repository), we nee...

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. This seemed like a good example use-case to demonstrate a couple of Nix commands I like to use, covering quick interactive one-off dev shells to fully declarative, hermetic, reproducible, shareable dev shells. Notably, you don’t need to use NixOS to run these commands! You can install and use Nix on any Linux system like Debian, Arch, etc., ...
