Can someone point me to a helpful beginners resource explaining some Linux basics? Like what is the difference between “distro”, which is what, like Ubuntu, fedora, Debian (? Or is that a category of distro?) And desktop environment which is what, KDE, Lubuntu, gnome? Like I don’t even know I have these categories right let alone understand why I’d pick one over another and what practical effects it will have- which apps will I/won’t I be able to install, etc…
I’m not expecting anyone to answer these questions for me, but if you could point me to something already written, I’d appreciate it.
The biggest shake-ups in a while outside we-don’t-use-X (no systemd, etc.) are the declarative distros like NixOS & Guix. You do the whole system setup & config thru a single file (or broken into multiple). Learning curve is very high for the config but the payoff is less things changing out from under you & setting up new machines & rolling back to working states without resorting to FS snapshots. They are good languages to learn for software development too where you want repeatable software.
