  • Programming Perl, 1st edition by Larry Wall and Randal Schwartz. This is the prototypical O'Reilly animal book, and is so well-known among true geeks that you can identify one just by asking them "Have you read the camel?" Avoid the second edition, which has worse typography and less content... to learn the new stuff in Perl 5, learn Perl 4 and then read the online documentation (see below).
  • Anything by Jakob Nielsen. His web site, useit.com, provides genuinely good advice on interface design backed up by experience. He has a new book out on web design.
  • man perl - It's not a book, but there's no section in Listology for creating a list of the best computer documentation. Perl's man pages suffer from the Unix documentation philosophy ("You already know this, so the documentation is a handy reminder") but still manage to be highly informative.
  • Philip and Alex's Guide to Web Publishing by Philip Greenspun and his dog. Genuinely practical advice on building web sites that require more than just static pages or a JavaScript image rollover. If you're cheap, read it online.
