I install and set up operating systems. It's something I do to my own computer regularly, but I'll cheerfully do for someone else because it's fun.
Linux is my favorite, but I can do Windows, Free/Open/Dragonfly BSD, Haiku, and given time to research others as well. I keep meaning to give NetBSD a shot...
It gives me a focused task with a specific end goal that requires some technical knowledge, but mostly preparation, research, and troubleshooting skills. The activity can sometimes lift me out of a depressive episode for a while.
I want to go to there…
