Not self hosted but look at your local library, I am in the US and my library has Mango Languages for free, and Duolingo does not seem to be the recommended way to really learn a new language.

Also faircamp and mirlo.space

Also check out Adresilo which uses Maps api to find a location then can feed it to the app of your choice.

His book Degrowth is great.

Indeed

I requested my library order it, hopefully they do. Checked my account and saw, "Your suggestion has been approved! The library will acquire the following Book: “Slow Down, The Degrowth Manifesto, by Kohei Saito”. "

I love my public library.

I know and Subsonic too. I used to love last.fm back before they were bought out, I could pick 3 bands and create a station, I have not been able to create anything as good since, paid or not.

thanks!!

It works now, I have only used Navidrome for like 30min and did not know about the web UI switches, that was the issue!

Nice, I setup a small VPS for it as a test, I need to redo it at home, its pretty neat.
