Since I had read a lot of books around programming and software management practices I never read Joel On Software seriously. I happened to read a lot of old articles by Joel (since 2001) recently. Each and every article taught me something new in software project management or programing in general. I actually grabbed the book that compiles all the articles., so I can read them offline. Highly recommened for any software developer, even if you have read the Mythical man month, the code complete and the pragmatic programmer series .
