The Jargon File, Version 4.2.2, 20 Aug 2000
Chapter 16
1. The operator's station of a mainframe. In times past, this was a privileged location that conveyed godlike powers to anyone with fingers on its keys. Under Unix and other modern timesharing OSes, such privileges are guarded by passwords instead, and the console is just the tty the system was booted from. Some of the mystique remains, however, and it is traditional for sysadmins to post urgent messages to all users from the console (on Unix, /dev/console). 2. On microcomputer Unix boxes, the main screen and keyboard (as opposed to character-only terminals talking to a serial port). Typically only the console can do real graphics or run X.

console jockey n.
See terminal junkie.
Node:content-free, Next:control-C, Previous:console jockey, Up:= C =
content-free adj.
[by analogy with techspeak `context-free'] Used of a message that adds nothing to the recipient's knowledge. Though this adjective is sometimes applied to flamage, it more usually connotes derision for communication styles that exalt form over substance or are centered on concerns irrelevant to the subject ostensibly at hand. Perhaps most used with reference to speeches by company presidents and other professional manipulators. "Content-free? Uh... that's anything printed on glossy paper." (See also four-color glossies.) "He gave a talk on the implications of electronic networks for postmodernism and the fin-de-siecle aesthetic. It was content-free."
Node:control-C, Next:control-O, Previous:content-free, Up:= C =
control-C vi.
1. "Stop whatever you are doing." From the interrupt character used on many operating systems to abort a running program. Considered silly. 2. interj. Among BSD Unix hackers, the canonical humorous response to "Give me a break!"
Node:control-O, Next:control-Q, Previous:control-C, Up:= C =
control-O vi.
"Stop talking." From the character used on some operating systems to abort output but allow the program to keep on running. Generally means that you are not interested in hearing anything more from that person, at least on that topic; a standard response to someone who is flaming. Considered silly. Compare control-S.
Node:control-Q, Next:control-S, Previous:control-O, Up:= C =
control-Q vi.
"Resume." From the ASCII DC1 or XON character (the pronunciation /X-on/ is therefore also used), used to undo a previous control-S.
Node:control-S, Next:Conway's Law, Previous:control-Q, Up:= C =
control-S vi.
"Stop talking for a second." From the ASCII DC3 or XOFF character (the pronunciation /X-of/ is therefore also used). Control-S differs from control-O in that the person is asked to stop talking (perhaps because you are on the phone) but will be allowed to continue when you're ready to listen to him -- as opposed to control-O, which has more of the meaning of "Shut up." Considered silly.
Node:Conway's Law, Next:cookbook, Previous:control-S, Up:= C =
Conway's Law prov.
The rule that the organization of the software and the organization of the software team will be congruent; commonly stated as "If you have four groups working on a compiler, you'll get a 4-pass compiler". The original statement was more general, "Organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations." This first appeared in the April 1968 issue of Datamation. Compare SNAFU principle.
The law was named after Melvin Conway, an early proto-hacker who wrote an assembler for the Burroughs 220 called SAVE. (The name `SAVE' didn't stand for anything; it was just that you lost fewer card decks and listings because they all had SAVE written on them.)
There is also Tom Cheatham's amendment of Conway's Law: "If a group of N persons implements a COBOL compiler, there will be N-1 passes. Someone in the group has to be the manager."
Node:cookbook, Next:cooked mode, Previous:Conway's Law, Up:= C =
cookbook n.
[from amateur electronics and radio] A book of small code segments that the reader can use to do various magic things in programs. One current example is the "PostScript Language Tutorial and Cookbook" by Adobe Systems, Inc (Addison-Wesley, ISBN 0-201-10179-3), also known as the Blue Book which has recipes for things like wrapping text around arbitrary curves and making 3D fonts. Cookbooks, slavishly followed, can lead one into voodoo programming, but are useful for hackers trying to monkey up small programs in unknown languages. This function is analogous to the role of phrasebooks in human languages.
Node:cooked mode, Next:cookie, Previous:cookbook, Up:= C =
cooked mode n.
[Unix, by opposition from raw mode] The normal character-input mode, with interrupts enabled and with erase, kill and other special-character interpretations performed directly by the tty driver. Oppose raw mode, rare mode. This term is techspeak under Unix but jargon elsewhere; other operating systems often have similar mode distinctions, and the raw/rare/cooked way of describing them has spread widely along with the C language and other Unix exports. Most generally, `cooked mode' may refer to any mode of a system that does extensive preprocessing before presenting data to a program.
Node:cookie, Next:cookie bear, Previous:cooked mode, Up:= C =
cookie n.
A handle, transaction ID, or other token of agreement between cooperating programs. "I give him a packet, he gives me back a cookie." The claim check you get from a dry-cleaning shop is a perfect mundane example of a cookie; the only thing it's useful for is to relate a later transaction to this one (so you get the same clothes back). Compare magic cookie; see also fortune cookie. Now mainstream in the specific sense of web-browser cookies.
Node:cookie bear, Next:cookie file, Previous:cookie, Up:= C =
cookie bear n. obs.
Original term, pre-Sesame-Street, for what is now universally called a cookie monster. A correspondent observes "In those days, hackers were actually getting their yucks from...sit down now...Andy Williams. Yes, that Andy Williams. Seems he had a rather hip (by the standards of the day) TV variety show. One of the best parts of the show was the recurring `cookie bear' sketch. In these sketches, a guy in a bear suit tried all sorts of tricks to get a cookie out of Williams. The sketches would always end with Williams shrieking (and I don't mean figuratively), `No cookies! Not now, not ever...NEVER!!!' And the bear would fall down. Great stuff."
Node:cookie file, Next:cookie jar, Previous:cookie bear, Up:= C =
cookie file n.
A collection of fortune cookies in a format that facilitates retrieval by a fortune program. There are several different cookie files in public distribution, and site admins often assemble their own from various sources including this lexicon.
Node:cookie jar, Next:cookie monster, Previous:cookie file, Up:= C =
cookie jar n.
An area of memory set aside for storing cookies. Most commonly heard in the Atari ST community; many useful ST programs record their presence by storing a distinctive magic number in the jar. Programs can inquire after the presence or otherwise of other programs by searching the contents of the jar.
Node:cookie monster, Next:copious free time, Previous:cookie jar, Up:= C =
cookie monster n.
[from the children's TV program "Sesame Street"] Any of a family of early (1970s) hacks reported on TOPS-10, ITS, Multics, and elsewhere that would lock up either the victim's terminal (on a time-sharing machine) or the console (on a batch mainframe), repeatedly demanding "I WANT A COOKIE". The required responses ranged in complexity from "COOKIE" through "HAVE A COOKIE" and upward. Folklorist Jan Brunvand (see FOAF) has described these programs as urban legends (implying they probably never existed) but they existed, all right, in several different versions. See also wabbit. Interestingly, the term `cookie monster' appears to be a retcon; the original term was cookie bear.
Node:copious free time, Next:copper, Previous:cookie monster, Up:= C =
copious free time n.
[Apple; orig. fr. the intro to Tom Lehrer's song "It Makes A Fellow Proud To Be A Soldier"] 1. [used ironically to indicate the speaker's lack of the quantity in question] A mythical schedule slot for accomplishing tasks held to be unlikely or impossible. Sometimes used to indicate that the speaker is interested in accomplishing the task, but believes that the opportunity will not arise. "I'll implement the automatic layout stuff in my copious free time." 2. [Archly] Time reserved for bogus or otherwise idiotic tasks, such as implementation of chrome, or the stroking of suits. "I'll get back to him on that feature in my copious free time."
Node:copper, Next:copy protection, Previous:copious free time, Up:= C =
copper n.
Conventional electron-carrying network cable with a core conductor of copper -- or aluminum! Opposed to light pipe or, say, a short-range microwave link.
Node:copy protection, Next:copybroke, Previous:copper, Up:= C =
copy protection n.
A class of methods for preventing incompetent pirates from stealing software and legitimate customers from using it. Considered silly.
Node:copybroke, Next:copycenter, Previous:copy protection, Up:= C =
copybroke /kop'ee-brohk/ adj.
1. [play on `copyright'] Used to describe an instance of a copy-protected program that has been `broken'; that is, a copy with the copy-protection scheme disabled. Syn. copywronged. 2. Copy-protected software which is unusable because of some bit-rot or bug that has confused the anti-piracy check. See also copy protection.
Node:copycenter, Next:copyleft, Previous:copybroke, Up:= C =
copycenter n.
[play on `copyright' and `copyleft'] 1. The copyright notice carried by the various flavors of freeware BSD. According to Kirk McKusick at BSDCon 1999: "The way it was characterized politically, you had copyright, which is what the big companies use to lock everything up; you had copyleft, which is free software's way of making sure they can't lock it up; and then Berkeley had what we called "copycenter", which is "take it down to the copy center and make as many copies as you want".
Node:copyleft, Next:copyparty, Previous:copycenter, Up:= C =
copyleft /kop'ee-left/ n.
[play on `copyright'] 1. The copyright notice (`General Public License') carried by GNU EMACS and other Free Software Foundation software, granting reuse and reproduction rights to all comers (but see also General Public Virus). 2. By extension, any copyright notice intended to achieve similar aims.
Node:copyparty, Next:copywronged, Previous:copyleft, Up:= C =
copyparty n.
[C64/amiga demoscene ]A computer party organized so demosceners can meet other in real life, and to facilitate software copying (mostly pirated software). The copyparty has become less common as the Internet makes communication easier. The demoscene has gradually evolved the demoparty to replace it.
Node:copywronged, Next:core, Previous:copyparty, Up:= C =
copywronged /kop'ee-rongd/ adj.
[play on `copyright'] Syn. for copybroke.
Node:core, Next:core cancer, Previous:copywronged, Up:= C =
core n.
Main storage or RAM. Dates from the days of ferrite-core memory; now archaic as techspeak most places outside IBM, but also still used in the Unix community and by old-time hackers or those who would sound like them. Some derived idioms are quite current; `in core', for example, means `in memory' (as opposed to `on disk'), and both core dump and the `core image' or `core file' produced by one are terms in favor. Some varieties of Commonwealth hackish prefer store.
Node:core cancer, Next:core dump, Previous:core, Up:= C =
core cancer n.
[rare] A process that exhibits a slow but inexorable resource leak -- like a cancer, it kills by crowding out productive `tissue'.
Node:core dump, Next:core leak, Previous:core cancer, Up:= C =
core dump n.
[common Iron Age jargon, preserved by Unix] 1. [techspeak] A copy of the contents of core, produced when a process is aborted by certain kinds of internal error. 2. By extension, used for humans passing out, vomiting, or registering extreme shock. "He dumped core. All over the floor. What a mess." "He heard about X and dumped core." 3. Occasionally used for a human rambling on pointlessly at great length; esp. in apology: "Sorry, I dumped core on you". 4. A recapitulation of knowledge (compare bits, sense 1). Hence, spewing all one knows about a topic (syn. brain dump), esp. in a lecture or answer to an exam question. "Short, concise answers are better than core dumps" (from the instructions to an exam at Columbia). See core.
Node:core leak, Next:Core Wars, Previous:core dump, Up:= C =
core leak n.
Syn. memory leak.
Node:Core Wars, Next:corge, Previous:core leak, Up:= C =
Core Wars n.
A game between `assembler' programs in a machine or machine simulator, where the objective is to kill your opponent's program by overwriting it. Popularized in the 1980s by A. K. Dewdney's column in "Scientific American" magazine, but described in "Software Practice And Experience" a decade earlier. The game was actually devised and played by Victor Vyssotsky, Robert Morris Sr., and Doug McIlroy in the early 1960s (Dennis Ritchie is sometimes incorrectly cited as a co-author, but was not involved). Their original game was called `Darwin' and ran on a IBM 7090 at Bell Labs. See core. For information on the modern game, do a web search for the `rec.games.corewar FAQ' or surf to the King Of The Hill site.
Node:corge, Next:cosmic rays, Previous:Core Wars, Up:= C =
corge /korj/ n.
[originally, the name of a cat] Yet another metasyntactic variable, invented by Mike Gallaher and propagated by the GOSMACS documentation. See grault.
Node:cosmic rays, Next:cough and die, Previous:corge, Up:= C =
cosmic rays n.
Notionally, the cause of bit rot. However, this is a semi-independent usage that may be invoked as a humorous way to handwave away any minor randomness that doesn't seem worth the bother of investigating. "Hey, Eric -- I just got a burst of garbage on my tube, where did that come from?" "Cosmic rays, I guess." Compare sunspots, phase of the moon. The British seem to prefer the usage `cosmic showers'; `alpha particles' is also heard, because stray alpha particles passing through a memory chip can cause single-bit errors (this becomes increasingly more likely as memory sizes and densities increase).
Factual note: Alpha particles cause bit rot, cosmic rays do not (except occasionally in spaceborne computers). Intel could not explain random bit drops in their early chips, and one hypothesis was cosmic rays. So they created the World's Largest Lead Safe, using 25 tons of the stuff, and used two identical boards for testing. One was placed in the safe, one outside. The hypothesis was that if cosmic rays were causing the bit drops, they should see a statistically significant difference between the error rates on the two boards. They did not observe such a difference. Further investigation demonstrated conclusively that the bit drops were due to alpha particle emissions from thorium (and to a much lesser degree uranium) in the encapsulation material. Since it is impossible to eliminate these radioactives (they are uniformly distributed through the earth's crust, with the statistically insignificant exception of uranium lodes) it became obvious that one has to design memories to withstand these hits.
Node:cough and die, Next:courier, Previous:cosmic rays, Up:= C =
cough and die v.
Syn. barf. Connotes that the program is throwing its hands up by design rather than because of a bug or oversight. "The parser saw a control-A in its input where it was looking for a printable, so it coughed and died." Compare die, die horribly, scream and die.
Node:courier, Next:cow orker, Previous:cough and die, Up:= C =
courier
[BBS & cracker cultures] A person who distributes newly cracked warez, as opposed to a server who makes them available for download or a leech who merely downloads them. Hackers recognize this term but don't use it themselves, as the act is not part of their culture. See also warez d00dz, cracker, elite.
Node:cow orker, Next:cowboy, Previous:courier, Up:= C =
cow orker n.
[Usenet] n. fortuitous typo for co-worker, widely used in Usenet, with perhaps a hint that orking cows is illegal. This term was popularized by Scott Adams (the creator of Dilbert) but already appears in the January 1996 version of the scary devil monastery FAQ. There are plausible reports that it was in use on _talk.bizarre_ as early as 1992. Compare hing, grilf, filk, newsfroup.
Node:cowboy, Next:CP/M, Previous:cow orker, Up:= C =
cowboy n.
[Sun, from William Gibson's cyberpunk SF] Synonym for hacker. It is reported that at Sun this word is often said with reverence.
Node:CP/M, Next:CPU Wars, Previous:cowboy, Up:= C =
CP/M /C-P-M/ n.
[Control Program/Monitor; later retconned to Control Program for Microcomputers] An early microcomputer OS written by hacker Gary Kildall for 8080- and Z80-based machines, very popular in the late 1970s but virtually wiped out by MS-DOS after the release of the IBM PC in 1981. Legend has it that Kildall's company blew its chance to write the OS for the IBM PC because Kildall decided to spend a day IBM's reps wanted to meet with him enjoying the perfect flying weather in his private plane. Many of CP/M's features and conventions strongly resemble those of early DEC operating systems such as TOPS-10, OS/8, RSTS, and RSX-11. See MS-DOS, operating system.
Node:CPU Wars, Next:crack, Previous:CP/M, Up:= C =
CPU Wars /C-P-U worz/ n.
A 1979 large-format comic by Chas Andres chronicling the attempts of the brainwashed androids of IPM (Impossible to Program Machines) to conquer and destroy the peaceful denizens of HEC (Human Engineered Computers). This rather transparent allegory featured many references to ADVENT and the immortal line "Eat flaming death, minicomputer mongrels!" (uttered, of course, by an IPM stormtrooper). The whole shebang is now available on the Web.
It is alleged that the author subsequently received a letter of appreciation on IBM company stationery from the head of IBM's Thomas J. Watson Research Laboratories (then, as now, one of the few islands of true hackerdom in the IBM archipelago). The lower loop of the B in the IBM logo, it is said, had been carefully whited out. See eat flaming death.
Node:crack, Next:crack root, Previous:CPU Wars, Up:= C =
crack
[warez d00dz] 1. v. To break into a system (compare cracker). 2. v. Action of removing the copy protection from a commercial program. People who write cracks consider themselves challenged by the copy protection measures. They will often do it as much to show that they are smarter than the developper who designed the copy protection scheme than to actually copy the program. 3. n. A program, instructions or patch used to remove the copy protection of a program or to uncripple features from a demo/time limited program. 4. An exploit.
Node:crack root, Next:cracker, Previous:crack, Up:= C =
crack root v.
[very common] To defeat the security system of a Unix machine and gain root privileges thereby; see cracking.
Node:cracker, Next:cracking, Previous:crack root, Up:= C =
cracker n.
One who breaks security on a system. Coined ca. 1985 by hackers in defense against journalistic misuse of hacker (q.v., sense 8). An earlier attempt to establish `worm' in this sense around 1981-82 on Usenet was largely a failure.
Use of both these neologisms reflects a strong revulsion against the theft and vandalism perpetrated by cracking rings. While it is expected that any real hacker will have done some playful cracking and knows many of the basic techniques, anyone past larval stage is expected to have outgrown the desire to do so except for immediate, benign, practical reasons (for example, if it's necessary to get around some security in order to get some work done).
Thus, there is far less overlap between hackerdom and crackerdom than the mundane reader misled by sensationalistic journalism might expect. Crackers tend to gather in small, tight-knit, very secretive groups that have little overlap with the huge, open poly-culture this lexicon describes; though crackers often like to describe themselves as hackers, most true hackers consider them a separate and lower form of life.
Ethical considerations aside, hackers figure that anyone who can't imagine a more interesting way to play with their computers than breaking into someone else's has to be pretty losing. Some other reasons crackers are looked down on are discussed in the entries on cracking and phreaking. See also samurai, dark-side hacker, and hacker ethic. For a portrait of the typical teenage cracker, see warez d00dz.
Node:cracking, Next:crank, Previous:cracker, Up:= C =
cracking n.
[very common] The act of breaking into a computer system; what a cracker does. Contrary to widespread myth, this does not usually involve some mysterious leap of hackerly brilliance, but rather persistence and the dogged repetition of a handful of fairly well-known tricks that exploit common weaknesses in the security of target systems. Accordingly, most crackers are only mediocre hackers.
Node:crank, Next:crapplet, Previous:cracking, Up:= C =
crank vt.
[from automotive slang] Verb used to describe the performance of a machine, especially sustained performance. "This box cranks (or, cranks at) about 6 megaflops, with a burst mode of twice that on vectorized operations."
Node:crapplet, Next:CrApTeX, Previous:crank, Up:= C =
crapplet n.
[portmanteau, crap + applet] A worthless applet, esp. a Java widget attached to a web page that doesn't work or even crashes your browser. Also spelled `craplet'.
Node:CrApTeX, Next:crash, Previous:crapplet, Up:= C =
CrApTeX /krap'tekh/ n.
[University of York, England] Term of abuse used to describe TeX and LaTeX when they don't work (when used by TeXhackers), or all the time (by everyone else). The non-TeX-enthusiasts generally dislike it because it is more verbose than other formatters (e.g. troff) and because (particularly if the standard Computer Modern fonts are used) it generates vast output files. See religious issues, TeX.
Node:crash, Next:crash and burn, Previous:CrApTeX, Up:= C =
crash
1. n. A sudden, usually drastic failure. Most often said of the system (q.v., sense 1), esp. of magnetic disk drives (the term originally described what happens when the air gap of a hard disk collapses). "Three lusers lost their files in last night's disk crash." A disk crash that involves the read/write heads dropping onto the surface of the disks and scraping off the oxide may also be referred to as a `head crash', whereas the term `system crash' usually, though not always, implies that the operating system or other software was at fault. 2. v. To fail suddenly. "Has the system just crashed?" "Something crashed the OS!" See down. Also used transitively to indicate the cause of the crash (usually a person or a program, or both). "Those idiots playing SPACEWAR crashed the system." 3. vi. Sometimes said of people hitting the sack after a long hacking run; see gronk out.
Node:crash and burn, Next:crawling horror, Previous:crash, Up:= C =
crash and burn vi.,n.
A spectacular crash, in the mode of the conclusion of the car-chase scene in the movie "Bullitt" and many subsequent imitators (compare die horribly). Sun-3 monitors losing the flyback transformer and lightning strikes on VAX-11/780 backplanes are notable crash and burn generators. The construction `crash-and-burn machine' is reported for a computer used exclusively for alpha or beta testing, or reproducing bugs (i.e., not for development). The implication is that it wouldn't be such a disaster if that machine crashed, since only the testers would be inconvenienced.
