Software engineer. I write here mostly so future me can find how I did something. Expect notes on Linux, shell and dev tooling, the occasional PCB, and how I organize my notes.
Upgrading a small server from Debian 12 to 13
Moving a small server from bookworm to trixie. The upgrade itself was uneventful. Preparing for it and checking afterwards took most of the time.
One year of Obsidian: what actually stuck
I started with a complicated folder hierarchy and a dozen plugins. A year later the vault is simpler, and I find things faster. Here鈥檚 what survived.
Notes from my first KiCad board
I designed and ordered my first PCB, a small USB-C powered sensor board. It worked on the first spin, mostly. These are the mistakes I鈥檇 like to not repeat.
A small restic backup setup for a Debian box
Encrypted, deduplicated nightly backups with restic, a systemd timer, and a retention policy. About 20 lines of config, and I actually tested the restore.
Replacing five version managers with mise
nvm, pyenv, goenv, a manually downloaded terraform, and a shell script for direnv. I replaced all of it with mise and one small config file per project.
Giving fish shell a real try
After years of bash and a growing pile of zsh plugins, I switched my interactive shell to fish. Here鈥檚 what I kept, what I changed, and the few things that still trip me up.
