The beginning of each entry is marked by a colon (`:') at the left margin. This convention helps out tools like hypertext browsers that benefit from knowing where entry boundaries are, but aren't as context-sensitive as humans.
In pure ASCII renderings of the Jargon File, you will see {} used to bracket words which themselves have entries in the File. This isn't done all the time for every such word, but it is done everywhere that a reminder seems useful that the term has a jargon meaning and one might wish to refer to its entry.
In this all-ASCII version, headwords for topic entries are distinguished from those for ordinary entries by being followed by "::" rather than ":"; similarly, references are surrounded by "{{" and"}}" rather than "{" and "}".
Defining instances of terms and phrases appear in `slanted type'. A defining instance is one which occurs near to or as part of an explanation of it.
Prefixed ** is used as linguists do; to mark examples of incorrect usage.
We follow the `logical' quoting convention described in the Writing Style section above. In addition, we reserve double quotes for actual excerpts of text or (sometimes invented) speech. Scare quotes (which mark a word being used in a nonstandard way), and philosopher's quotes (which turn an utterance into the string of letters or words that name it) are both rendered with single quotes.
References such as `malloc(3)' and `patch(1)' are to Unix facilities (some of which, such as `patch(1)', are actually freeware distributed over Usenet). The Unix manuals use `foo(n)' to refer to item foo in section (n) of the manual, where n=1 is utilities, n=2 is system calls, n=3 is C library routines, n=6 is games, and n=8 (where present) is system administration utilities. Sections 4, 5, and 7 of the manuals have changed roles frequently and in any case are not referred to in any of the entries.
Various abbreviations used frequently in the lexicon are summarized here:
abbrev. abbreviation adj. adjective adv. adverb alt. alternate cav. caveat conj. conjunction esp. especially excl. exclamation imp. imperative interj. interjection n. noun obs. obsolete pl. plural poss. possibly pref. prefix prob. probably prov. proverbial quant. quantifier suff. suffix syn. synonym (or synonymous with) v. verb (may be transitive or intransitive) var. variant vi. intransitive verb vt. transitive verbWhere alternate spellings or pronunciations are given, alt. separates two possibilities with nearly equal distribution, while var. prefixes one that is markedly less common than the primary.
Where a term can be attributed to a particular subculture or is known to have originated there, we have tried to so indicate. Here is a list of abbreviations used in etymologies:
Amateur Packet Radio A technical culture of ham-radio sites using AX.25 and TCP/IP for wide-area networking and BBS systems. Berkeley University of California at Berkeley BBN Bolt, Beranek & Newman Cambridge the university in England (*not* the city in Massachusetts where MIT happens to be located!) CMU Carnegie-Mellon University Commodore Commodore Business Machines DEC The Digital Equipment Corporation Fairchild The Fairchild Instruments Palo Alto development group FidoNet See the FidoNet entry IBM International Business Machines MIT Massachusetts Institute of Technology; esp. the legendary MIT AI Lab culture of roughly 1971 to 1983 and its feeder groups, including the Tech Model Railroad Club NRL Naval Research Laboratories NYU New York University OED The Oxford English Dictionary Purdue Purdue University SAIL Stanford Artificial Intelligence Laboratory (at Stanford University) SI From Syst`eme International, the name for the standard conventions of metric nomenclature used in the sciences Stanford Stanford University Sun Sun Microsystems TMRC Some MITisms go back as far as the Tech Model Railroad Club (TMRC) at MIT c. 1960. Material marked TMRC is from "An Abridged Dictionary of the TMRC Language", originally compiled by Pete Samson in 1959 UCLA University of California at Los Angeles UK the United Kingdom (England, Wales, Scotland, Northern Ireland) Usenet See the Usenet entry WPI Worcester Polytechnic Institute, site of a very active community of PDP-10 hackers during the 1970s WWW The World-Wide-Web. XEROX PARC XEROX's Palo Alto Research Center, site of much pioneering research in user interface design and networking Yale Yale UniversitySome other etymology abbreviations such as Unix and PDP-10 refer to technical cultures surrounding specific operating systems, processors, or other environments. The fact that a term is labelled with any one of these abbreviations does not necessarily mean its use is confined to that culture. In particular, many terms labelled `MIT' and `Stanford' are in quite general use. We have tried to give some indication of the distribution of speakers in the usage notes; however, a number of factors mentioned in the introduction conspire to make these indications less definite than might be desirable.
A few new definitions attached to entries are marked [proposed]. These are usually generalizations suggested by editors or Usenet respondents in the process of commenting on previous definitions of those entries. These are *not* represented as established jargon.
