oh these books there are still pretty much all around 'old' IT companies, displayed in shelves and bookcases, as artifacts that explains what were old languages and systems. I love the retro futuristic vibe of the cover of some of these. And of their content. They invite the reader to leap into the future with bash, explained how Linux used to work, how past versions of .NET and Java were breakthroughs, how to code with XML,... As a junior who has hardly read any of these, I find them pretty poetic, and I like the reflection they bring on IT jobs. The languages and technologies will change, but good looking code is timeless
