  * Eric Raymond, [The Art of Unix Programming](http://www.catb.org/esr/writings/taoup/html/index.html): also explains a lot of design
  * Mark Pilgrim, [Dive Into Python](http://diveintopython.org/): "a Python book for experienced programmers"
  * Eric Raymond, ed., [The Jargon File](http://catb.org/~esr/jargon/): a lot of hacker terminology and lore, plus quite a few interesting articles near the beginning.
