the Niagara launcher is still the only app I’ve bought on Play Store, and I’ve been very happy with it for maybe 5-6 years now

This looks like a Jinja template, so definitely supposed so be populated by something else first. Yaml is basically just a prettier Json so it wouldn’t support something like that section on its own.

Check Gentoomen Library and anarcho-copy, both have a huge curated list of books on everything, including networking.

My setup is Navidrome, Soulseek and MusicBrainz Picard, each hosted in a docker container.

Whatever music I can’t or don’t care to buy directly on Bandcamp i find on Soulseek. Then, I run the downloaded files through Picard which tags and renames them automatically for me. After which, I put them into the Navidrome directory, it picks them up and lets you stream it in a browser or any app that supports Subsonic servers. I use Feishin on my desktop and Symfonium on my phone for that.
