The Jargon File is a glossary and usage dictionary of slang used by computer programmers. 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 (BBN), 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).
The concept of the file began with the Tech Model Railroad Club (TMRC) that came out of early TX-0 and PDP-1 hackers in the 1950s, where the term hacker emerged and the ethic, philosophies and some of the nomenclature emerged.
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. [1] [2] 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 last term was coined by Eric Raymond.
In 1976, Mark Crispin, having seen an announcement about the File on the SAIL computer, FTPed a copy of the File to the MIT AI Lab. He noticed that it was hardly restricted to "AI words", and so stored the file on his directory, named as "AI:MRC;SAIL JARGON" ("AI" lab computer, directory "MRC", file "SAIL JARGON").
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 1983. Richard Stallman was prominent among the contributors, adding many MIT and ITS-related coinages. The Incompatible Timesharing System (ITS) was named to distinguish it from another early MIT computer operating system, Compatible Time-Sharing System (CTSS).
In 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 Steele's 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). It included all of Steele's Crunchly cartoons. The other Jargon-1 editors (Raphael Finkel, Don Woods, and Mark Crispin) contributed to this revision, as did 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 ease 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 associated proprietary 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 [3] 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' ITS. [4]
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 DEC. 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. [5]
As mentioned in some editions: [6]
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's; the content exerted a strong and continuing influence on hackish slang and humor. Even as the advent of the microcomputer and other trends fueled a tremendous expansion of hackerdom, the File (and related materials like 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 passed from living document to icon and remained essentially untouched for seven years.
A new revision was begun in 1990, which contained nearly the entire text of a late version of Jargon-1 (a few obsolete PDP-10-related entries were dropped after consultation with the editors of Steele-1983). It merged in about 80% of the Steele-1983 text, omitting some framing material and a very few entries introduced in Steele-1983 that are now only of historical interest.
The new version cast a wider net than the old Jargon File; its aim was to cover not just AI or PDP-10 hacker culture but all of the technical computing cultures in which the true hacker-nature is manifested. More than half of the entries derived from Usenet and represented jargon then current in the C and Unix communities, but special efforts were made to collect jargon from other cultures including IBM PC programmers, Amiga fans, Mac enthusiasts, and even the IBM mainframe world. [7]
Eric Raymond maintained the new File with assistance from Guy Steele, and is the credited editor of the print version of it, The New Hacker's Dictionary (published by MIT Press in 1991); hereafter Raymond-1991. Some of the changes made under his watch were controversial; early critics accused Raymond of unfairly changing the file's focus to the Unix hacker culture instead of the older hacker cultures where the Jargon File originated. Raymond has responded by saying that the nature of hacking had changed and the Jargon File should report on hacker culture, and not attempt to enshrine it. [8] After the second edition of NHD (MIT Press, 1993; hereafter Raymond-1993), Raymond was accused of adding terms reflecting his own politics and vocabulary, [9] even though he says that entries to be added are checked to make sure that they are in live use, not "just the private coinage of one or two people". [10]
The Raymond version was revised again, to include terminology from the nascent subculture of the public Internet and the World Wide Web, and published by MIT Press as The New Hacker's Dictionary, Third Edition, in 1996.
As of January 2016 [update] , no updates have been made to the official Jargon File since 2003. A volunteer editor produced two updates, reflecting later influences (mostly excoriated) from text messaging language, LOLspeak, and Internet slang in general; the last was produced in January 2012. [11]
Despite its tongue-in-cheek approach, multiple other style guides and similar works have cited The New Hacker's Dictionary as a reference, and even recommended following some of its "hackish" best practices. The Oxford English Dictionary has used the NHD as a source for computer-related neologisms. [12] The Chicago Manual of Style , the leading American academic and book-publishing style guide, beginning with its 15th edition (2003) explicitly defers, for "computer writing", to the quotation punctuation style – logical quotation – recommended by the essay "Hacker Writing Style" in The New Hacker's Dictionary (and cites NHD for nothing else). [13] The 16th edition (2010, and the current issue as of 2016 [update] ) does likewise. [14] The National Geographic Style Manual lists NHD among only 8 specialized dictionaries, out of 22 total sources, on which it is based. That manual is the house style of NGS publications, and has been available online for public browsing since 1995. [15] The NGSM does not specify what, in particular, it drew from the NHD or any other source.
Aside from these guides and the Encyclopedia of New Media, the Jargon file, especially in print form, is frequently cited for both its definitions and its essays, by books and other works on hacker history, cyberpunk subculture, computer jargon and online style, and the rise of the Internet as a public medium, in works as diverse as the 20th edition of A Bibliography of Literary Theory, Criticism and Philology edited by José Ángel García Landa (2015); Wired Style: Principles of English Usage in the Digital Age by Constance Hale and Jessie Scanlon of Wired magazine (1999); Transhumanism: The History of a Dangerous Idea by David Livingstone (2015); Mark Dery's Flame Wars: The Discourse of Cyberculture (1994) and Escape Velocity: Cyberculture at the End of the Century (2007); Beyond Cyberpunk! A Do-it-yourself Guide to the Future by Gareth Branwyn and Peter Sugarman (1991); and numerous others.
Time magazine used The New Hacker's Dictionary (Raymond-1993) as the basis for an article about online culture in the November 1995 inaugural edition of the "Time Digital" department. NHD was cited by name on the front page of The Wall Street Journal .[ when? ] Upon the release of the second edition, Newsweek used it as a primary source, and quoted entries in a sidebar, for a major article on the Internet and its history.[ when? ] The MTV show This Week in Rock used excerpts from the Jargon File in its "CyberStuff" segments. Computing Reviews used one of the Jargon File's definitions on its December 1991 cover.
On October 23, 2003, The New Hacker's Dictionary was used in a legal case. SCO Group cited the 1996 edition definition of "FUD" (fear, uncertainty and doubt), which dwelt on questionable IBM business practices, in a legal filing in the civil lawsuit SCO Group, Inc. v. International Business Machines Corp. [16] (In response, Raymond added SCO to the entry in a revised copy of the Jargon File, feeling that SCO's own practices deserved similar criticism. [17] )
The book is particularly noted for helping (or at least trying) to preserve the distinction between a hacker (a consummate programmer) and a cracker (a computer criminal); even though not reviewing the book in detail, both the London Review of Books [18] and MIT Technology Review [19] remarked on it in this regard. In a substantial entry on the work, the Encyclopedia of New Media by Steve Jones (2002) observed that this defense of the term hacker was a motivating factor for both Steele's and Raymond's print editions: [20]
The Hacker's Dictionary and The New Hacker's Dictionary sought to celebrate hacker culture, provide a repository of hacking history for younger and future hackers, and perhaps most importantly, to represent hacker culture in a positive light to the general public. In the early 1990s in particular, many news stories emerged portraying hackers as law-breakers with no respect for the personal privacy or property of others. Raymond wanted to show some of the positive values of hacker culture, particularly the hacker sense of humor. Because love of humorous wordplay is a strong element of hacker culture, a slang dictionary works quite well for such purposes.
PC Magazine in 1984, stated that The Hacker's Dictionary was superior to most other computer-humor books, and noted its authenticity to "hard-core programmers' conversations", especially slang from MIT and Stanford. [21] Reviews quoted by the publisher include: William Safire of The New York Times referring to the Raymond-1991 NHD as a "sprightly lexicon" and recommending it as a nerdy gift that holiday season [22] (this reappeared in his "On Language" column again in mid-October 1992); Hugh Kenner in Byte suggesting that it was so engaging that one's reading of it should be "severely timed if you hope to get any work done"; [23] and Mondo 2000 describing it as "slippery, elastic fun with language", as well as "not only a useful guidebook to very much un-official technical terms and street tech slang, but also a de facto ethnography of the early years of the hacker culture". [24] Positive reviews were also published in academic as well as computer-industry publications, including IEEE Spectrum , New Scientist , PC Magazine , PC World , Science , and (repeatedly) Wired.
US game designer Steve Jackson, writing for Boing Boing magazine in its pre-blog, print days, described NHD's essay "A Portrait of J. Random Hacker" as "a wonderfully accurate pseudo-demographic description of the people who make up the hacker culture". He was nevertheless critical of Raymond's tendency to editorialize, even "flame", and of the Steele cartoons, which Jackson described as "sophomoric, and embarrassingly out of place beside the dry and sophisticated humor of the text". He wound down his review with some rhetorical questions: [25]
[W]here else will you find, for instance, that one attoparsec per microfortnight is approximately equal to one inch per second? Or an example of the canonical use of canonical? Or a definition like "A cuspy but bogus raving story about N random broken people"?
The third print edition garnered additional coverage, in the usual places like Wired (August 1996), and even in mainstream venues, including People magazine (October 21, 1996). [12]
The terms foobar, foo, bar, baz, qux, quux, and others are used as metasyntactic variables and placeholder names in computer programming or computer-related documentation. They have been used to name entities such as variables, functions, and commands whose exact identity is unimportant and serve only to demonstrate a concept. The style guide for Google developer documentation recommends against using them as example project names because they are unclear and can cause confusion.
A hacker is a person skilled in information technology who achieves goals by non-standard means. The term has become associated in popular culture with a security hacker – someone with knowledge of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them. In a positive connotation, though, hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques to collect evidence on criminals and other malicious actors. This could include using anonymity tools to mask their identities online and pose as criminals.
The Knights of the Lambda Calculus is a semi-fictional organization of expert Lisp and Scheme hackers. The name refers to the lambda calculus, a mathematical formalism invented by Alonzo Church, with which Lisp is intimately connected, and references the Knights Templar.
Lisp machines are general-purpose computers designed to efficiently run Lisp as their main software and programming language, usually via hardware support. They are an example of a high-level language computer architecture. In a sense, they were the first commercial single-user workstations. Despite being modest in number Lisp machines commercially pioneered many now-commonplace technologies, including effective garbage collection, laser printing, windowing systems, computer mice, high-resolution bit-mapped raster graphics, computer graphic rendering, and networking innovations such as Chaosnet. Several firms built and sold Lisp machines in the 1980s: Symbolics, Lisp Machines Incorporated, Texas Instruments, and Xerox. The operating systems were written in Lisp Machine Lisp, Interlisp (Xerox), and later partly in Common Lisp.
Maclisp is a programming language, a dialect of the language Lisp. It originated at the Massachusetts Institute of Technology's (MIT) Project MAC in the late 1960s and was based on Lisp 1.5. Richard Greenblatt was the main developer of the original codebase for the PDP-6; Jon L. White was responsible for its later maintenance and development. The name Maclisp began being used in the early 1970s to distinguish it from other forks of PDP-6 Lisp, notably BBN Lisp.
Structure and Interpretation of Computer Programs (SICP) is a computer science textbook by Massachusetts Institute of Technology professors Harold Abelson and Gerald Jay Sussman with Julie Sussman. It is known as the "Wizard Book" in hacker culture. It teaches fundamental principles of computer programming, including recursion, abstraction, modularity, and programming language design and implementation.
The hacker culture is a subculture of individuals who enjoy—often in collective effort—the intellectual challenge of creatively overcoming the limitations of software systems or electronic hardware, to achieve novel and clever outcomes. The act of engaging in activities in a spirit of playfulness and exploration is termed hacking. However, the defining characteristic of a hacker is not the activities performed themselves, but how it is done and whether it is exciting and meaningful. Activities of playful cleverness can be said to have "hack value" and therefore the term "hacks" came about, with early examples including pranks at MIT done by students to demonstrate their technical aptitude and cleverness. The hacker culture originally emerged in academia in the 1960s around the Massachusetts Institute of Technology (MIT)'s Tech Model Railroad Club (TMRC) and MIT Artificial Intelligence Laboratory. Hacking originally involved entering restricted areas in a clever way without causing any major damage. Some famous hacks at the Massachusetts Institute of Technology were placing of a campus police cruiser on the roof of the Great Dome and converting the Great Dome into R2-D2.
The Tech Model Railroad Club (TMRC) is a student organization at the Massachusetts Institute of Technology (MIT). Historically, it has been a wellspring of hacker culture and the oldest such hacking group in North America. Formed in 1946, its HO scale layout specializes in the automated operation of model trains.
Incompatible Timesharing System (ITS) is a time-sharing operating system developed principally by the MIT Artificial Intelligence Laboratory, with help from Project MAC. The name is the jocular complement of the MIT Compatible Time-Sharing System (CTSS).
Guy Lewis Steele Jr. is an American computer scientist who has played an important role in designing and documenting several computer programming languages and technical standards.
Richard D. Greenblatt is an American computer programmer. Along with Bill Gosper, he may be considered to have founded the hacker community, and holds a place of distinction in the communities of the programming language Lisp and of the Massachusetts Institute of Technology (MIT) Artificial Intelligence Laboratory.
Tom Knight is an American synthetic biologist and computer engineer, who was formerly a senior research scientist at the MIT Computer Science and Artificial Intelligence Laboratory, a part of the MIT School of Engineering. He now works at the synthetic biology company Ginkgo Bioworks, which he cofounded in 2008.
In Unix operating systems, the term wheel refers to a user account with a wheel bit, a system setting that provides additional special system privileges that empower a user to execute restricted commands that ordinary user accounts cannot access.
Donald R. Woods is an American hacker and computer programmer. He is best known for his role in the development of the Colossal Cave Adventure game.
New Implementation of LISP (NIL) is a programming language, a dialect of the language Lisp, developed at the Massachusetts Institute of Technology (MIT) during the 1970s, and intended to be the successor to the language Maclisp. It is a 32-bit implementation, and was in part a response to Digital Equipment Corporation's (DEC) VAX computer. The project was headed by Jon L White, with a stated goal of maintaining compatibility with MacLisp while fixing many of its problems.
Emacs, originally named EMACS, is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on GNU Emacs, directly descended from the original, is ongoing; its latest version is 29.4, released June 2024.
In computer slang, J. Random Hacker is an arbitrary programmer (hacker).
A mythical figure like the Unknown Soldier; the archetypal hacker nerd. This term is one of the oldest in the hacker's jargon, apparently going back to MIT in the 1960s. may originally have been inspired by 'J. Fred Muggs', a show-biz chimpanzee whose name was a household word back in the early days of TMRC, and was probably influenced by 'J. Presper Eckert' ".
The AI Memos are a series of influential memorandums and technical reports published by the MIT AI Lab, Massachusetts Institute of Technology, United States. They cover Artificial Intelligence, a field of computer science.
TENEX is an operating system developed in 1969 by BBN for the PDP-10, which later formed the basis for Digital Equipment Corporation's TOPS-20 operating system.
Robert Alan Saunders was an American computer scientist, most famous for his involvement with Spacewar. Saunders joined the Tech Model Railroad Club (TMRC) led by Alan Kotok, Peter Samson, and himself. They then met Marvin Minsky and other influential pioneers in what was then known as Artificial Intelligence.
The [MIT] AI lab became a virtual battleground between two sides, and the two firms, especially Symbolics, hired away many of the lab's remaining hackers.
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.
In April 1983, the PDP-10-centered cultures that had nourished the [Jargon] 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.
For related matters in computer writing, see Eric S. Raymond, 'Hacker Writing Style,' in The New Hacker's Dictionary (bibliog. 5).
On 23 October 2003, the Jargon File achieved the dubious honor of being cited in the SCO-vs.-IBM lawsuit. See the FUD entry for details.The correct version number is actually 4.4.7, as given in the rest of the documents there.
