Most cs degrees I’ve seen, including my own include an operating systems course.

“How a computer works”

It really depends what you mean, and at what depth; theres a tone of stuff in there. Even then I think your mostly wrong, you just notice/remember the ones who are inept at using their computer.

If you mean run program x on os y, well then sure

This is a two for one deal then

I don’t actually care, but when I have in the past (around 2006 era) it “just worked”, while other distros i was using required more hand holding (gentoo, redhat, slackware). I suspect most distros are just fine now a days (using debian now and it seems just fine).

I am not currently using it but it’s always been fine whenever I have. What’s broken?
