The New Hacker's Dictionary by Eric S. Raymond (each kindness read aloud TXT) 📖

words are listed in order to make the jargon senses clear;

where the text does not specify that a straight technical sense is

under discussion, these are marked with `[techspeak]' as an etymology.

Some entries have a primary sense marked this way, with subsequent

jargon meanings explained in terms of it.

We have also tried to indicate (where known) the apparent origins of

terms. The results are probably the least reliable information in the

lexicon, for several reasons. For one thing, it is well known that

many hackish usages have been independently reinvented multiple times,

even among the more obscure and intricate neologisms. It often seems

that the generative processes underlying hackish jargon formation have

an internal logic so powerful as to create substantial parallelism

across separate cultures and even in different languages! For another,

the networks tend to propagate innovations so quickly that `first use'

is often impossible to pin down. And, finally, compendia like this one

alter what they observe by implicitly stamping cultural approval on

terms and widening their use.

Despite these problems, the organized collection of jargon-related

oral history for the new compilations has enabled us to put to rest

quite a number of folk etymologies, place credit where credit is due,

and illuminate the early history of many important hackerisms such as

[36]kluge, [37]cruft, and [38]foo. We believe specialist

lexicographers will find many of the historical notes more than

casually instructive.

Revision History

The original Jargon File was a collection of hacker jargon from

technical cultures including 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 (BBN), Carnegie-Mellon University

(CMU), and Worcester Polytechnic Institute (WPI).

The Jargon File (hereafter referred to as jargon-1' orthe File')

was begun by Raphael Finkel at Stanford in 1975. From this time until

the plug was finally pulled on the SAIL computer in 1991, the File was

named AIWORD.RF[UP,DOC] there. Some terms in it date back considerably

earlier ([42]frob and some senses of [43]moby, for instance, go back

to the Tech Model Railroad Club at MIT and are believed to date at

least back to the early 1960s). The revisions of jargon-1 were all

unnumbered and may be collectively considered `Version 1'.

In 1976, Mark Crispin, having seen an announcement about the File on

the SAIL computer, [44]FTPed a copy of the File to MIT. He noticed

that it was hardly restricted to `AI words' and so stored the file on

his directory as AI:MRC;SAIL JARGON.

The file was quickly renamed JARGON > (the `>' caused versioning under

ITS) as a flurry of enhancements were made by Mark Crispin and Guy L.

Steele Jr. Unfortunately, amidst all this activity, nobody thought of

correcting the term jargon' toslang' until the compendium had

already become widely known as the Jargon File.

Raphael Finkel dropped out of active participation shortly thereafter

and Don Woods became the SAIL contact for the File (which was

subsequently kept in duplicate at SAIL and MIT, with periodic

resynchronizations).

The File expanded by fits and starts until about 1983; Richard

Stallman was prominent among the contributors, adding many MIT and

ITS-related coinages.

In Spring 1981, a hacker named Charles Spurgeon got a large chunk of

the File published in Stewart Brand's "CoEvolution Quarterly" (issue

29, pages 26-35) with illustrations by Phil Wadler and Guy Steele

(including a couple of the Crunchly cartoons). This appears to have

been the File's first paper publication.

A late version of jargon-1, expanded with commentary for the mass

market, was edited by Guy Steele into a book published in 1983 as "The

Hacker's Dictionary" (Harper & Row CN 1082, ISBN 0-06-091082-8). The

other jargon-1 editors (Raphael Finkel, Don Woods, and Mark Crispin)

contributed to this revision, as did Richard M. Stallman and Geoff

Goodfellow. This book (now out of print) is hereafter referred to as

`Steele-1983' and those six as the Steele-1983 coauthors.

Shortly after the publication of Steele-1983, the File effectively

stopped growing and changing. Originally, this was due to a desire to

freeze the file temporarily to facilitate the production of

Steele-1983, but external conditions caused the `temporary' freeze to

become permanent.

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 [45]TWENEX

system rather than a host for the AI hackers' beloved [46]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 [47]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 hacker 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 [48]Some 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 [49]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.
