No, these are not the hardcore geeky things. These are more properly classified “Geek Culture”. But they’re good reads:
Life With Unix: A Guide For Everyone, by Don Libes and Sandy Ressler: a little dated, written in 1989, but still an enjoyable journey into the world that gave us Unix.
The Mythical Man-Month: Essays On Software Engineering, by Frederick Brooks. This one is really dated (some would say obsolete). It was written in 1975. But there are universal truths buried inside.
The Cuckoo’s Egg, by Cliff Stoll. An early story on tracking a hacker.
The Soul Of A New Machine, by Tracy Kidder. The story of Data General’s attempt to build a 32-bit minicomputer during the late 1970s.
And a fiction work:
The Adolescence Of P1, by Thomas Ryan. The first computer fiction I ever read, if you don’t count “2001”, and still the best. I suspect this might be hard to find, but worth it if you do.
