Started Blue Prince, but to be honest I haven't gotten past the initial "RNG wall" and I'm sorta over it. I'm 5 hours in and continue to get the same rooms I've documented in detail in my notes with little new to show for it, and while I have some leads and puzzle pieces, nothing fits. Not particularly excited about a lot of the small repeat puzzles anymore either. I get the impression that I just need one or two pieces of knowledge that the game is refusing to provide to me. Kinda hoping that the good old trick of complaining on the internet will make things work out.

Windows prefers to deactivate or minimize the write cache on removable devices, most of the common Linux distros generally don't make such changes. Microsoft has a very good reason for that default: not a lot of people actually use the "safely remove hardware" option and if the cache is enabled, using and waiting for that is a hard requirement for the data to have actually made its way onto the drive.
I don't think it really makes a lot of sense to look for FOSS alternatives based on country of maintainer origin when it's something popular enough to be shipped by a lot of independent Linux distros and supported by local IT consultants in more or less any country. That said, to my knowledge, lighttpd is mostly German in origin and is actively maintained. It definitively lost to nginx in the great popularity contest but I don't think it's really any worse.

Self-hostable, but it seems like an absolute behemoth of an application if their "non-production-use-only" docker-compose file is to be believed, and I couldn't find any production-ready deployment instructions on a quick skim. No obvious signs of federation and I didn't see anything on their roadmap, not sure it would make a lot of sense for this though.
That's what I've been trying, yesterday ended up being a little more fruitful (internet complaining trick worked!) and luckily gave me more interesting rooms, though I'm not convinced it was any action on my part that did it.
