Jargon File

The Jargon File is a glossary and usage dictionary of computer programmer slang. The original Jargon File was a collection of terms from technical cultures such as the MIT AI Lab, the Stanford AI Lab (SAIL) and others of the old ARPANET AI/LISP/PDP-10 communities, including Bolt, Beranek and Newman, Carnegie Mellon University, and Worcester Polytechnic Institute. It was published in paperback form in 1983 as The Hacker's Dictionary (edited by Guy Steele), revised in 1991 as The New Hacker's Dictionary (ed. Eric S. Raymond; third edition published 1996).

1975 to 1983

The Jargon File (referred to here as "Jargon-1" or "the File") was made by Raphael Finkel at Stanford in 1975. From that time until the plug was finally pulled on the SAIL computer in 1991, the File was named "AIWORD.RF[UP,DOC]" ("[UP,DOC]" was a system directory for "User Program DOCumentation" on the WAITS operating system). Some terms, such as frob, foo and mung are believed to date back to the early 1950s from the Tech Model Railroad Club at MIT and documented in the 1959 Dictionary of the TMRC Language compiled by Peter Samson. The revisions of Jargon-1 were all unnumbered and may be collectively considered "version 1". Note that it was always called "AIWORD" or "the Jargon file", never "the File"; the latter term was coined by Eric Raymond.
