This site is written by one person who runs the servers described in the guides: a handful of VPS instances in Europe, a small Kubernetes cluster, a Nextcloud install, an internet radio and a few voice gadgets on a desk.
Every command in a guide here was run on a machine that someone pays for, usually me. When something broke, the guide says so. When I have not tested a step, the guide says that too.
What this site is not: a news aggregator, a reprint of vendor documentation, or a place for sponsored posts dressed up as reviews. Some links are affiliate links, always marked as such: see the affiliate disclosure.
