I’m conducting my spring cleaning and getting rid of programming books that are no relevant (goodbye J2ME). Garbage collecting, as it were. It’s interesting to see that my oldest books are still relevant (again, the GC analogy applies – older references tend to stick around, newer ones are more likely to be ephemeral). Thanks to Linux especially, but also to MacOSX, the GNU and X Windows stuff is still around (not so much Motif, but it has descendants in KDE, if I recall correctly). Lisp is still around, even though it’s not going as strong as I’d like (I wish I still had my copy of the original Lisp Machine Manual). My collection of Inside Macintosh books – OK, that’s nostalgia. And the Microsoft books? That’s just out of fear that I might have to look at some old code.
