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;
- HAProxy
- KeepaliveD
Not easy to learn, but once they’re running, they both go on forever.
The OS itself, Debian. If I have to pick a component, Mate Panel. Compared to the Windows 11 start menu, it’s useful, customizableand has no ads. My IT department at work can’t even figure out how to remove the Windows 11 start menu ads from my computer.
