The sort of program that once set up, just ticks along without fuss or bother forever.
For me, as I’m replacing the vms today which I set up five years ago and haven’t needed to touch since;

- KeepaliveD
Not easy to learn, but once they’re running, they both go on forever.
Big fan of the KDE suite of software. I’ve tried alternatives, but always come back to plasma and associated software
