One that I don't recommend is Hackers and Painters. I found it pretty dissapointing. The articles were not well written and all had a pretty shallow point that could have been covered in a page or two. Many of them seemed very self-serving too, with an overtone of "I got rich with my company, so that proves I'm right." Graham has established himself as a LISP expert, but I don't think his musings on things outside of that domain are worth your time.
in reply to Which non-Perl books made you a better (?:Perl )?Programmer?
I know this books is something of a sacred cow in the Perl community, because he tells us things we want to hear, like we're smart and Java programmers are idiots. Nevertheless, I think some of the Java programmers have more to teach you than this book does.
There is an amusing critique of the title essay in the book here.
