On my PC and all my home servers I keep my root partition at 10GB and haven’t had any issues (although I keep everything that isn’t hardware related or a system utility in home).
On my PC I crammed arch, all of KDE (+extra KDE utilities), and some other system stuff like LACT and distrobox in the 10GB root partition and run almost everything else as a flatpak installed to home.
On my servers I do the same thing but all my services are in podman containers in /opt.
Having all the software needed to make the machine work be isolated from my custom home junk makes me feel better, and I like that I can mount root as read-only to make it immutable
Idk I haven’t seen an AI that writes acceptable C/C++ yet (to be honest I haven’t looked that hard)… So as long as my projects focus is low level, thin, maintainable code, I can still do things AI won’t be able to for a long time.
I recognize that being free to write code however I want makes me privileged, and others don’t have that freedom.
Despite that, I am afraid of what will happen to the open source tools I depend on. None of us write our code alone.
