The AI Lab culture had been hit hard in the late 1970s by funding cuts and the resulting administrative decision to use vendor-supported hardware and software instead of homebrew whenever possible. At MIT, most AI work had turned to dedicated LISP Machines. At the same time, the commercialization of AI technology lured some of the AI Lab's best and brightest away to startups along the Route 128 strip in Massachusetts and out West in Silicon Valley. The startups built LISP machines for MIT; the central MIT-AI computer became a {TWENEX} system rather than a host for the AI hackers' beloved {ITS}.
The Stanford AI Lab had effectively ceased to exist by 1980, although the SAIL computer continued as a Computer Science Department resource until 1991. Stanford became a major {TWENEX} site, at one point operating more than a dozen TOPS-20 systems; but by the mid-1980s most of the interesting software work was being done on the emerging BSD UNIX standard.
In April 1983, the PDP-10-centered cultures that had nourished the File were dealt a death-blow by the cancellation of the Jupiter project at Digital Equipment Corporation. The File's compilers, already dispersed, moved on to other things. Steele-1983 was partly a monument to what its authors thought was a dying tradition; no one involved realized at the time just how wide its influence was to be.
By the mid-1980s the File's content was dated, but the legend that had grown up around it never quite died out. The book, and softcopies obtained off the ARPANET, circulated even in cultures far removed from MIT and Stanford; the content exerted a strong and continuing influence on hackish language and humor. Even as the advent of the microcomputer and other trends fueled a tremendous expansion of hackerdom, the File (and related materials such as the AI Koans in Appendix A) came to be seen as a sort of sacred epic, a hacker-culture Matter of Britain chronicling the heroic exploits of the Knights of the Lab. The pace of change in hackerdom at large accelerated tremendously —- but the Jargon File, having passed from living document to icon, remained essentially untouched for seven years.
This revision contains nearly the entire text of a late version of jargon-1 (a few obsolete PDP-10-related entries were dropped after careful consultation with the editors of Steele-1983). It merges in about 80% of the Steele-1983 text, omitting some framing material and a very few entries introduced in Steele-1983 that are now also obsolete.
This new version casts a wider net than the old Jargon File; its aim is to cover not just AI or PDP-10 hacker culture but all the technical computing cultures wherein the true hacker-nature is manifested. More than half of the entries now derive from {USENET} and represent jargon now current in the C and UNIX communities, but special efforts have been made to collect jargon from other cultures including IBM PC programmers, Amiga fans, Mac enthusiasts, and even the IBM mainframe world.
Eric S. Raymond <eric@snark.thyrsus.com> maintains the new File with assistance from Guy L. Steele Jr. <gls@think.com>; these are the persons primarily reflected in the File's editorial `we', though we take pleasure in acknowledging the special contribution of the other coauthors of Steele-1983. Please email all additions, corrections, and correspondence relating to the Jargon File to jargon@thyrsus.com (UUCP-only sites without connections to an autorouting smart site can use …!uunet!snark!jargon).
(Warning: other email addresses appear in this file *but are not guaranteed to be correct* later than the revision date on the first line. *Don't* email us if an attempt to reach your idol bounces —- we have no magic way of checking addresses or looking up people.)
The 2.9.6 version became the main text of `The New Hacker's Dictionary', by Eric Raymond (ed.), MIT Press 1991, ISBN 0-262-68069-6. The maintainers are committed to updating the on-line version of the Jargon File through and beyond paper publication, and will continue to make it available to archives and public-access sites as a trust of the hacker community.
Here is a chronology of the high points in the recent on-line revisions:
