The New Hacker's Dictionary

The New Hacker's Dictionary is written by Eric S. Raymond,   an American software developer, author of the widely cited 1997 essay and 1999 book The Cathedral and the Bazaar and other works, and open-source software advocate. This document is a collection of slang terms used by various subcultures of computer hackers. Though some technical material is included for background and flavor, it is not a technical dictionary; what we describe here is the language hackers use among themselves for fun, social communication, and technical debate.
