True. Building Linux from scratch will teach you everything in a modern CS curriculum, including the `cut' operator in Prolog, Boyce-Codd Normal Form, and alpha-beta pruning. \end{snark}

All of those "very" "useful" in huge variety of CS related jobs /s

Could someone explain to me USian school schema pls ? Especially what difference collage vs university. For comparision in Poland we have schema (+- 1 year):

- 0 - 6 preschool

- 7 - 15 basic school (mandatory)

- 16 - 19 middle school

- 20+ university or polytechnique

And middle school generally divides into: a) 3 year of craft school, workforce after; or b) 4 years of general learning school, no craft knowledge after, expected to go to university after or be clerk, or ..., unspecified; or c) ~4 years technical school in specific craft with "qualified technik" diploma quasi low level "engineer" (have some knowledge to be responsible for things), maybe polytechnique after or uni

At unis typical degrees: master, phd, professor.

So where in such schema collage is located ?

College is tertiary education, ie university or similar. My understanding is that the distinction between college and university is an organizational one, not the curriculum. But I’m not from the US.

What you call middle school they call high school.

I have a similar background and got a lot out of my CS program, its about what you put into it. Sorry you had a bad experience, that can absolutely make it harder to invest.

Perhaps you missed the point of college if all you did were things within your comfort zone

I would guess GP meant "about Linux."

I had the same experience with college. I'd been using Linux for years and learned nothing new about Linux in college. It was nice because the class moved fast and a lot of people who had never Linuxed or CLIed in their lives really struggled to get through it and keep up.

Maybe they missed your point, but plenty of people with expertise go to college in order to get a piece of paper that allows them to work. Making it a middle-class spiritual rite of passage isn't the only way to do college right.

They could've taken other classes then? Lift the lid a bit, learn about computer architecture, VLSI, transistor physics, fabrication, analog devices, MEMS, antenna design. If you already know a lot about computer science, it's unsurprising that you wouldn't learn too many radically new things just computer science classes, but you don't have to do that. Stay curious and seek out things you don't know.

If you approach college or any education with the attitude that you know everything already, you will likely learn about as much as if that were actually true.
