You could implement NOPASS for the specific commands you need for a service user. Still better than just using root.

Imo this would be impossible to implement. The user can just remove whatever mark was inserted.

I'll also leave this here: https://github.com/ggerganov/llama.cpp

I've also gone down that rabbit hole and found Vivictpp pretty good. It allows you to play two videos so you can swipe between them like imgsli you mentioned.

There's a whole range measurements trying to approximate quality differences between a video source and encode. PSNR, SSIM, VMAF, MS-SSIM
All of them with some strong areas and tricks you can use to cheat them.

*every application using xWayland looks like crap.

Native Wayland apps work great with fractional scaling.

There are reports of issues with creating an account, as Hetzner also has some form of protection against fraud.

That being said I myself never had any issues and been renting a dedicated server for years now. Their cloud is also amazingly cheap (in Europe).

The EU doesn't include a bunch of countries on the continent of Europe

Then Europe is a bunch of countries wearing a bikini and lots of accessories. There's no one part that covers all of it, some accessories strongly clash with each other and you have random bracelets everywhere.

The Thunar bulk renamer is relatively good, but recently I wanted to name images based on the capture date. Probably very tedious without the right GUI tool, while it's just one line using exiftool in the terminal. (I don't know it off the top of my head)

Similarly, I just extracted the audio only from a video using ffmpeg in like 10s.
ffmpeg -i video.mkv -c:a copy out.mka

Interesting, Firefox did crash more often for me on Wayland, but I hadn't dug into it further yet.
Let's see if this reduces crashing again.

Maintaining a vacuum over long distances is really fucking hard.
You'd be better served utilising existing rail infrastructure and improving that to make high speed trains possible.

Because streaming on mobile is a huge usecase for many people

Streaming a full 4k movie rip takes more bandwidth than most people would have available on the go. Plex/Jellyfin can offer transcoding on the server for such usecases.
