Very interesting articles from famous leaders the Open Source

(Linux), Larry Wall (Perl)... Every programmer should read this book! There's
a lot of philosophy in it.

An article from Eric Raymond about how a software cathedral
can be built more efficiently in a bazaar style, than in a well structured
