Node:gnubie, Next:GNUMACS, Previous:GNU, Up:= G =

gnubie /noo'bee/ n.

Written-only variant of newbie in common use on IRC channels, which implies specifically someone who is new to the Linux/open source/free software world.

Node:GNUMACS, Next:go flatline, Previous:gnubie, Up:= G =

GNUMACS /gnoo'maks/ n.

[contraction of `GNU EMACS'] Often-heard abbreviated name for the GNU project's flagship tool, EMACS. Used esp. in contrast with GOSMACS.

Node:go flatline, Next:go root, Previous:GNUMACS, Up:= G =

go flatline v.

[from cyberpunk SF, refers to flattening of EEG traces upon brain-death] (also adjectival `flatlined'). 1. To die, terminate, or fail, esp. irreversibly. In hacker parlance, this is used of machines only, human death being considered somewhat too serious a matter to employ jargon-jokes about. 2. To go completely quiescent; said of machines undergoing controlled shutdown. "You can suffer file damage if you shut down Unix but power off before the system has gone flatline." 3. Of a video tube, to fail by losing vertical scan, so all one sees is a bright horizontal line bisecting the screen.

Node:go root, Next:go-faster stripes, Previous:go flatline, Up:= G =

go root vi.

[Unix; common] To temporarily enter root mode in order to perform a privileged operation. This use is deprecated in Australia, where v. `root' is a synonym for "fuck".

Node:go-faster stripes, Next:GoAT, Previous:go root, Up:= G =

go-faster stripes n.

[UK] Syn. chrome. Mainstream in some parts of UK.

Node:GoAT, Next:gobble, Previous:go-faster stripes, Up:= G =

GoAT //

[Usenet] Abbreviation: "Go Away, Troll". See troll.

Node:gobble, Next:Godwin's Law, Previous:GoAT, Up:= G =

gobble vt.

1. To consume, usu. used with `up'. "The output spy gobbles characters out of a tty output buffer." 2. To obtain, usu. used with `down'. "I guess I'll gobble down a copy of the documentation tomorrow." See also snarf.

Node:Godwin's Law, Next:Godzillagram, Previous:gobble, Up:= G =

Godwin's Law prov.

[Usenet] "As a Usenet discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one." There is a tradition in many groups that, once this occurs, that thread is over, and whoever mentioned the Nazis has automatically lost whatever argument was in progress. Godwin's Law thus practically guarantees the existence of an upper bound on thread length in those groups. However there is also a widely- recognized codicil that any intentional triggering of Godwin's Law in order to invoke its thread-ending effects will be unsuccessful.

Node:Godzillagram, Next:golden, Previous:Godwin's Law, Up:= G =

Godzillagram /god-zil'*-gram/ n.

[from Japan's national hero] 1. A network packet that in theory is a broadcast to every machine in the universe. The typical case is an IP datagram whose destination IP address is [255.255.255.255]. Fortunately, few gateways are foolish enough to attempt to implement this case! 2. A network packet of maximum size. An IP Godzillagram has 65,536 octets. Compare super source quench, Christmas tree packet, martian.

Node:golden, Next:golf-ball printer, Previous:Godzillagram, Up:= G =

golden adj.

[prob. from folklore's `golden egg'] When used to describe a magnetic medium (e.g., `golden disk', `golden tape'), describes one containing a tested, up-to-spec, ready-to-ship software version. Compare platinum-iridium.

Node:golf-ball printer, Next:gonk, Previous:golden, Up:= G =

golf-ball printer n. obs.

The IBM 2741, a slow but letter-quality printing device and terminal based on the IBM Selectric typewriter. The `golf ball' was a little spherical frob bearing reversed embossed images of 88 different characters arranged on four parallels of latitude; one could change the font by swapping in a different golf ball. The print element spun and jerked alarmingly in action and when in motion was sometimes described as an `infuriated golf ball'. This was the technology that enabled APL to use a non-EBCDIC, non-ASCII, and in fact completely non-standard character set. This put it 10 years ahead of its time -- where it stayed, firmly rooted, for the next 20, until character displays gave way to programmable bit-mapped devices with the flexibility to support other character sets.

Node:gonk, Next:gonkulator, Previous:golf-ball printer, Up:= G =

gonk /gonk/ vi.,n.

1. To prevaricate or to embellish the truth beyond any reasonable recognition. In German the term is (mythically) `gonken'; in Spanish the verb becomes `gonkar'. "You're gonking me. That story you just told me is a bunch of gonk." In German, for example, "Du gonkst mich" (You're pulling my leg). See also gonkulator. 2. [British] To grab some sleep at an odd time; compare gronk out.

Node:gonkulator, Next:gonzo, Previous:gonk, Up:= G =

gonkulator /gon'kyoo-lay-tr/ n.

[common; from the 1960s "Hogan's Heroes" TV series] A pretentious piece of equipment that actually serves no useful purpose. Usually used to describe one's least favorite piece of computer hardware. See gonk.

Node:gonzo, Next:Good Thing, Previous:gonkulator, Up:= G =

gonzo /gon'zoh/ adj.

[from Hunter S. Thompson] 1. With total commitment, total concentration, and a mad sort of panache. (Thompson's original sense.) 2. More loosely: Overwhelming; outrageous; over the top; very large, esp. used of collections of source code, source files, or individual functions. Has some of the connotations of moby and hairy, but without the implication of obscurity or complexity.

Node:Good Thing, Next:gopher, Previous:gonzo, Up:= G =

Good Thing n.,adj.

[very common; often capitalized; always pronounced as if capitalized.] 1. Self-evidently wonderful to anyone in a position to notice: "A language that manages dynamic memory automatically for you is a Good Thing." 2. Something that can't possibly have any ill side-effects and may save considerable grief later: "Removing the self-modifying code from that shared library would be a Good Thing." 3. When said of software tools or libraries, as in "YACC is a Good Thing", specifically connotes that the thing has drastically reduced a programmer's work load. Oppose Bad Thing.

Node:gopher, Next:gopher hole, Previous:Good Thing, Up:= G =

gopher n.

A type of Internet service first floated around 1991 and obsolesced around 1995 by the World Wide Web. Gopher presents a menuing interface to a tree or graph of links; the links can be to documents, runnable programs, or other gopher menus arbitrarily far across the net.

Some claim that the gopher software, which was originally developed at the University of Minnesota, was named after the Minnesota Gophers (a sports team). Others claim the word derives from American slang `gofer' (from "go for", dialectal "go fer"), one whose job is to run and fetch things. Finally, observe that gophers dig long tunnels, and the idea of tunneling through the net to find information was a defining metaphor for the developers. Probably all three things were true, but with the first two coming first and the gopher-tunnel metaphor serendipitously adding flavor and impetus to the project as it developed out of its concept stage.

Node:gopher hole, Next:gorets, Previous:gopher, Up:= G =

gopher hole n.

1. Any access to a gopher. 2. [Amateur Packet Radio] The terrestrial analog of a wormhole (sense 2), from which this term was coined. A gopher hole links two amateur packet relays through some non-ham radio medium.

Node:gorets, Next:gorilla arm, Previous:gopher hole, Up:= G =

gorets /gor'ets/ n.

The unknown ur-noun, fill in your own meaning. Found esp. on the Usenet newsgroup _alt.gorets_, which seems to be a running contest to redefine the word by implication in the funniest and most peculiar way, with the understanding that no definition is ever final. [A correspondent from the Former Soviet Union informs me that `gorets' is Russian for `mountain dweller'. Another from France informs me that `goret' is archaic French for a young pig --ESR] Compare frink.

Node:gorilla arm, Next:gorp, Previous:gorets, Up:= G =

gorilla arm n.

The side-effect that destroyed touch-screens as a mainstream input technology despite a promising start in the early 1980s. It seems the designers of all those spiffy touch-menu systems failed to notice that humans aren't designed to hold their arms in front of their faces making small motions. After more than a very few selections, the arm begins to feel sore, cramped, and oversized -- the operator looks like a gorilla while using the touch screen and feels like one afterwards. This is now considered a classic cautionary tale to human-factors designers; "Remember the gorilla arm!" is shorthand for "How is this going to fly in real use?".

Node:gorp, Next:GOSMACS, Previous:gorilla arm, Up:= G =

gorp /gorp/ n.

[CMU: perhaps from the canonical hiker's food, Good Old Raisins and Peanuts] Another metasyntactic variable, like foo and bar.

Node:GOSMACS, Next:Gosperism, Previous:gorp, Up:= G =

GOSMACS /goz'maks/ n.

[contraction of `Gosling EMACS'] The first EMACS-in-C implementation, predating but now largely eclipsed by GNUMACS. Originally freeware; a commercial version was modestly popular as `UniPress EMACS' during the 1980s. The author, James Gosling, went on to invent NeWS and the programming language Java; the latter earned him demigod status.

Node:Gosperism, Next:gotcha, Previous:GOSMACS, Up:= G =

Gosperism /gos'p*r-izm/ n.

A hack, invention, or saying due to elder days arch-hacker R. William (Bill) Gosper. This notion merits its own term because there are so many of them. Many of the entries in HAKMEM are Gosperisms; see also life.

Node:gotcha, Next:GPL, Previous:Gosperism, Up:= G =

gotcha n.

A misfeature of a system, especially a programming language or environment, that tends to breed bugs or mistakes because it both enticingly easy to invoke and completely unexpected and/or unreasonable in its outcome. For example, a classic gotcha in C is the fact that if (a=b) {code;} is syntactically valid and sometimes even correct. It puts the value of b into a and then executes code if a is non-zero. What the programmer probably meant was if (a==b) {code;}, which executes code if a and b are equal.

Node:GPL, Next:GPV, Previous:gotcha, Up:= G =

GPL /G-P-L/ n.

Abbreviation for `General Public License' in widespread use; see copyleft, General Public Virus. Often mis-expanded as `GNU Public License'.

Node:GPV, Next:grault, Previous:GPL, Up:= G =

GPV /G-P-V/ n.

Abbrev. for General Public Virus in widespread use.

Node:grault, Next:gray goo, Previous:GPV, Up:= G =

grault /grawlt/ n.

Yet another metasyntactic variable, invented by Mike Gallaher and propagated by the GOSMACS documentation. See corge.

Node:gray goo, Next:Great Renaming, Previous:grault, Up:= G =

gray goo n.

A hypothetical substance composed of sagans of sub-micron-sized self-replicating robots programmed to make copies of themselves out of whatever is available. The image that goes with the term is one of the entire biosphere of Earth being eventually converted to robot goo. This is the simplest of the nanotechnology disaster scenarios, easily refuted by arguments from energy requirements and elemental abundances. Compare blue goo.

Node:Great Renaming, Next:Great Runes, Previous:gray goo, Up:= G =

Great Renaming n.

The flag day in 1987 on which all of the non-local groups on the Usenet had their names changed from the net.- format to the current multiple-hierarchies scheme. Used esp. in discussing the history of newsgroup names. "The oldest sources group is _comp.sources.misc_; before the Great Renaming, it was _net.sources_." There is a Great Renaming FAQ on the Web.

Node:Great Runes, Next:Great Worm, Previous:Great Renaming, Up:= G =

Great Runes n.

Uppercase-only text or display messages. Some archaic operating systems still emit these. See also runes, smash case, fold case.

There is a widespread legend (repeated by earlier versions of this entry, though tagged as folklore) that the uppercase-only support of various old character codes and I/O equipment was chosen by a religious person in a position of power at the Teletype Company because supporting both upper and lower cases was too expensive and supporting lower case only would have made it impossible to spell `God' correctly. Not true; the upper-case interpretation of teleprinter codes was well established by 1870, long before Teletype was even founded.

Node:Great Worm, Next:great-wall, Previous:Great Runes, Up:= G =

Great Worm n.

The 1988 Internet worm perpetrated by RTM. This is a play on Tolkien (compare elvish, elder days). In the fantasy history of his Middle Earth books, there were dragons powerful enough to lay waste to entire regions; two of these (Scatha and Glaurung) were known as "the Great Worms". This usage expresses the connotation that the RTM crack was a sort of devastating watershed event in hacker history; certainly it did more to make non-hackers nervous about the Internet than anything before or since.

Node:great-wall, Next:Green Book, Previous:Great Worm, Up:= G =

great-wall vi.,n.

[from SF fandom] A mass expedition to an oriental restaurant, esp. one where food is served family-style and shared. There is a common heuristic about the amount of food to order, expressed as "Get N - 1 entrees"; the value of N, which is the number of people in the group, can be inferred from context (see N). See oriental food, ravs, stir-fried random.

Node:Green Book, Next:green bytes, Previous:great-wall, Up:= G =

Green Book n.

1. One of the three standard PostScript references: "PostScript Language Program Design", bylined `Adobe Systems' (Addison-Wesley, 1988; QA76.73.P67P66 ISBN 0-201-14396-8); see also Red Book, Blue Book, and the White Book (sense 2). 2. Informal name for one of the three standard references on SmallTalk: "Smalltalk-80: Bits of History, Words of Advice", by Glenn Krasner (Addison-Wesley, 1983; QA76.8.S635S58; ISBN 0-201-11669-3) (this, too, is associated with blue and red books). 3. The "X/Open Compatibility Guide", which defines an international standard Unix environment that is a proper superset of POSIX/SVID; also includes descriptions of a standard utility toolkit, systems administrations features, and the like. This grimoire is taken with particular seriousness in Europe. See Purple Book. 4. The IEEE 1003.1 POSIX Operating Systems Interface standard has been dubbed "The Ugly Green Book". 5. Any of the 1992 standards issued by the CCITT's tenth plenary assembly. These include, among other things, the X.400 email standard and the Group 1 through 4 fax standards. See also book titles.

Node:green bytes, Next:green card, Previous:Green Book, Up:= G =

green bytes n.

(also `green words') 1. Meta-information embedded in a file, such as the length of the file or its name; as opposed to keeping such information in a separate description file or record. The term comes from an IBM user's group meeting (ca. 1962) at which these two approaches were being debated and the diagram of the file on the blackboard had the `green bytes' drawn in green. 2. By extension, the non-data bits in any self-describing format. "A GIF file contains, among other things, green bytes describing the packing method for the image." Compare out-of-band, zigamorph, fence (sense 1).

Node:green card, Next:green lightning, Previous:green bytes, Up:= G =

green card n.

[after the "IBM System/360 Reference Data" card] A summary of an assembly language, even if the color is not green and not a card. Less frequently used now because of the decrease in the use of assembly language. "I'll go get my green card so I can check the addressing mode for that instruction."

The original green card became a yellow card when the System/370 was introduced, and later a yellow booklet. An anecdote from IBM refers to a scene that took place in a programmers' terminal room at Yorktown in 1978. A luser overheard one of the programmers ask another "Do you have a green card?" The other grunted and passed the first a thick yellow booklet. At this point the luser turned a delicate shade of olive and rapidly left the room, never to return.

In fall 2000 it was reported from Electronic Data Systems that the green card for 370 machines has been a blue-green booklet since 1989.

Node:green lightning, Next:green machine, Previous:green card, Up:= G =

green lightning n.

[IBM] 1. Apparently random flashing streaks on the face of 3278-9 terminals while a new symbol set is being downloaded. This hardware bug was left deliberately unfixed, as some genius within IBM suggested it would let the user know that `something is happening'. That, it certainly does. Later microprocessor-driven IBM color graphics displays were actually programmed to produce green lightning! 2. [proposed] Any bug perverted into an alleged feature by adroit rationalization or marketing. "Motorola calls the CISC cruft in the 88000 architecture `compatibility logic', but I call it green lightning". See also feature (sense 6).

Node:green machine, Next:Green's Theorem, Previous:green lightning, Up:= G =

green machine n.

A computer or peripheral device that has been designed and built to military specifications for field equipment (that is, to withstand mechanical shock, extremes of temperature and humidity, and so forth). Comes from the olive-drab `uniform' paint used for military equipment.

Node:Green's Theorem, Next:greenbar, Previous:green machine, Up:= G =

Green's Theorem prov.

[TMRC] For any story, in any group of people there will be at least one person who has not heard the story. A refinement of the theorem states that there will be exactly one person (if there were more than one, it wouldn't be as bad to re-tell the story). [The name of this theorem is a play on a fundamental theorem in calculus. --ESR]

Node:greenbar, Next:grep, Previous:Green's Theorem, Up:= G =

greenbar n.

A style of fanfolded continuous-feed paper with alternating green and white bars on it, especially used in old-style line printers. This slang almost certainly dates way back to mainframe days.

Node:grep, Next:gribble, Previous:greenbar, Up:= G =

grep /grep/ vi.

[from the qed/ed editor idiom g/_re_/p, where _re_ stands for a regular expression, to Globally search for the Regular Expression and Print the lines containing matches to it, via Unix grep(1)] To rapidly scan a file or set of files looking for a particular string or pattern (when browsing through a large set of files, one may speak of `grepping around'). By extension, to look for something by pattern. "Grep the bulletin board for the system backup schedule, would you?" See also vgrep.

[It has also been alleged that the source is from the title of a paper "A General Regular Expression Parser" -ESR]

Node:gribble, Next:grilf, Previous:grep, Up:= G =

gribble n.

Random binary data rendered as unreadable text. Noise characters in a data stream are displayed as gribble. Modems with mismatched bitrates usually generate gribble (more specifically, baud barf). Dumping a binary file to the screen is an excellent source of gribble, and (if the bell/speaker is active) headaches.

Node:grilf, Next:grind, Previous:gribble, Up:= G =

grilf // n.

Girlfriend. Like newsfroup and filk, a typo reincarnated as a new word. Seems to have originated sometime in 1992 on Usenet. [A friend tells me there was a Lloyd Biggle SF novel "Watchers Of The Dark", in which alien species after species goes insane and begins to chant "Grilf! Grilf!". A human detective eventually determines that the word means "Liar!" I hope this has nothing to do with the popularity of the Usenet term. --ESR]

Node:grind, Next:grind crank, Previous:grilf, Up:= G =

grind vt.

1. [MIT and Berkeley; now rare] To prettify hardcopy of code, especially LISP code, by reindenting lines, printing keywords and comments in distinct fonts (if available), etc. This usage was associated with the MacLISP community and is now rare; prettyprint was and is the generic term for such operations. 2. [Unix] To generate the formatted version of a document from the nroff, troff, TeX, or Scribe source. 3. [common] To run seemingly interminably, esp. (but not necessarily) if performing some tedious and inherently useless task. Similar to crunch or grovel. Grinding has a connotation of using a lot of CPU time, but it is possible to grind a disk, network, etc. See also hog. 4. To make the whole system slow. "Troff really grinds a PDP-11." 5. `grind grind' excl. Roughly, "Isn't the machine slow today!"

Node:grind crank, Next:gripenet, Previous:grind, Up:= G =

grind crank n. //

A mythical accessory to a terminal. A crank on the side of a monitor, which when operated makes a zizzing noise and causes the computer to run faster. Usually one does not refer to a grind crank out loud, but merely makes the appropriate gesture and noise. See grind.

Historical note: At least one real machine actually had a grind crank -- the R1, a research machine built toward the end of the days of the great vacuum tube computers, in 1959. R1 (also known as `The Rice Institute Computer' (TRIC) and later as `The Rice University Computer' (TRUC)) had a single-step/free-run switch for use when debugging programs. Since single-stepping through a large program was rather tedious, there was also a crank with a cam and gear arrangement that repeatedly pushed the single-step button. This allowed one to `crank' through a lot of code, then slow down to single-step for a bit when you got near the code of interest, poke at some registers using the console typewriter, and then keep on cranking.

Node:gripenet, Next:gritch, Previous:grind crank, Up:= G =

gripenet n.

[IBM] A wry (and thoroughly unofficial) name for IBM's internal VNET system, deriving from its common use by IBMers to voice pointed criticism of IBM management that would be taboo in more formal channels.

Node:gritch, Next:grok, Previous:gripenet, Up:= G =

gritch /grich/

[MIT] 1. n. A complaint (often caused by a glitch). 2. vi. To complain. Often verb-doubled: "Gritch gritch". 3. A synonym for glitch (as verb or noun).

Interestingly, this word seems to have a separate history from glitch, with which it is often confused. Back in the early 1960s, when `glitch' was strictly a hardware-tech's term of art, the Burton House dorm at M.I.T. maintained a "Gritch Book", a blank volume, into which the residents hand-wrote complaints, suggestions, and witticisms. Previous years' volumes of this tradition were maintained, dating back to antiquity. The word "gritch" was described as a portmanteau of "gripe" and "bitch". Thus, sense 3 above is at least historically incorrect.

Node:grok, Next:gronk, Previous:gritch, Up:= G =

grok /grok/, var. /grohk/ vt.

[from the novel "Stranger in a Strange Land", by Robert A. Heinlein, where it is a Martian word meaning literally `to drink' and metaphorically `to be one with'] The emphatic form is `grok in fullness'. 1. To understand, usually in a global sense. Connotes intimate and exhaustive knowledge. Contrast zen, which is similar supernal understanding experienced as a single brief flash. See also glark. 2. Used of programs, may connote merely sufficient understanding. "Almost all C compilers grok the void type these days."

Node:gronk, Next:gronk out, Previous:grok, Up:= G =

gronk /gronk/ vt.

[popularized by Johnny Hart's comic strip "B.C." but the word apparently predates that] 1. To clear the state of a wedged device and restart it. More severe than `to frob' (sense 2). 2. [TMRC] To cut, sever, smash, or similarly disable. 3. The sound made by many 3.5-inch diskette drives. In particular, the microfloppies on a Commodore Amiga go "grink, gronk".

Node:gronk out, Next:gronked, Previous:gronk, Up:= G =

gronk out vi.

To cease functioning. Of people, to go home and go to sleep. "I guess I'll gronk out now; see you all tomorrow."
