Guy Steele, The Hacker's Dictionary, Harper and Row, 1983.
A funny and quite accurate guide to the jargon of the best of the best of computer scientists. This dialect is to programmers what Chuck Yeager's drawl is to test pilots. I thought the book was a joke until I joined an artificial intelligence lab and found everybody really did talk that way.
In this context, incidentally, "hacker" has a much broader and more respectable meaning than its popular use as a synonym for "computer criminal". Virus weenies and digital peeping Toms do not deserve so honorable a label.
