Curiously, I do buy and read tech books. My hobby is legacy OS kernel research so I bought some second handed books on old Linux (kernel 1.2) and NT (3.1). It is fun to research so I don’t use AI often for side projects.
Are you thinking of getting in to NeXTSTEP 3.3/OpenStep 4.2?
I enjoy reading really old programming books, the 1997 edition of Learning Perl mentioned in the article being a perfect example. I don't fret over the exercises, but if it's well-written it gives a glimpse into how people thought about technology/code/computers at that point in time, like the tech equivalent of flipping through old newspapers.
