I wonder if there’s already a git extension to automatically stash the working tree on every clean/reset/checkout operation…

you can make it sort the first k elements and it will still be O(1). Set k high enough and it might even be useful

If this is about line endings, surely a simple shell or python script could correct them?

Young and impressionable kids? I started playing the original MW2 when I was 11.

Any Linux distro should work for the setup you want. I have radarr, sonarr, sabnzbd, deluge and jellyfin running on an Arch setup, but something more accessible like Ubuntu or Debian should work fine (although I’m not familiar with whether the Pi4 can power those heavier distros). If you’re comfortable with the command line, it doesn’t matter much which distro you pick since you can install and configure all those apps over ssh.
