Oh I'm sure it runs perfectly fine in a container, it's just not my preferred setup.

Last time I checked, radicale and baikal were the sensible options. I went with radicale, no regrets, but not in a container.

I don't know of such an alternative. A quick solution would be to use something like GeoNotes to take geolocated notes.

As far as a self-hosted solution goes, I'd just like to point out that you wouldn't need a self-hosted database of places. You could query Ouverture (or Google, OSM, etc.) for places near you, and you'd just need to store the check-in on your server with a basic API. This is an interesting problem, and not super hard to implement.

I think it's usually invoice in Germany (to patient / insurance). Some psychoanalysts demand to paid in cash which I find hilarious.
