Part 24
(For more about the legendary foo counters, see TMRC.) This definition used Bill Holman's nonsense word, only then two decades old and demonstrably still live in popular culture and slang, to a ha ha only serious analogy with esoteric Tibetan Buddhism. Today's hackers would find it difficult to resist elaborating a joke like that, and it is not likely 1959's were any less susceptible. Almost the entire staff of what later became the MIT AI Lab was involved with TMRC, and the word spread from there.
Node:foobar, Next:fool, Previous:foo, Up:= F =
foobar n.
[very common] Another widely used metasyntactic variable; see foo for etymology. Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972. Hackers do not generally use this to mean FUBAR in either the slang or jargon sense. See also Fred Foobar. In RFC1639, "FOOBAR" was made an abbreviation for "FTP Operation Over Big Address Records", but this was an obvious backronym.
Node:fool, Next:fool file, Previous:foobar, Up:= F =
fool n.
As used by hackers, specifically describes a person who habitually reasons from obviously or demonstrably incorrect premises and cannot be persuaded by evidence to do otherwise; it is not generally used in its other senses, i.e., to describe a person with a native incapacity to reason correctly, or a clown. Indeed, in hackish experience many fools are capable of reasoning all too effectively in executing their errors. See also cretin, loser, fool file.
The Algol 68-R compiler used to initialize its storage to the character string "F00LF00LF00LF00L..." because as a pointer or as a floating point number it caused a crash, and as an integer or a character string it was very recognizable in a dump. Sadly, one day a very senior professor at Nottingham University wrote a program that called him a fool. He proceeded to demonstrate the correctness of this assertion by lobbying the university (not quite successfully) to forbid the use of Algol on its computers. See also DEADBEEF.
Node:fool file, Next:Foonly, Previous:fool, Up:= F =
fool file n.
[Usenet] A notional repository of all the most dramatically and abysmally stupid utterances ever. An entire subgenre of sig blocks consists of the header "From the fool file:" followed by some quote the poster wishes to represent as an immortal gem of dimwittery; for this usage to be really effective, the quote has to be so obviously wrong as to be laughable. More than one Usenetter has achieved an unwanted notoriety by being quoted in this way.
Node:Foonly, Next:footprint, Previous:fool file, Up:= F =
Foonly n.
1. The PDP-10 successor that was to have been built by the Super Foonly project at the Stanford Artificial Intelligence Laboratory along with a new operating system. (The name itself came from FOO NLI, an error message emitted by a PDP-10 assembler at SAIL meaning "FOO is Not a Legal Identifier". The intention was to leapfrog from the old DEC timesharing system SAIL was then running to a new generation, bypassing TENEX which at that time was the ARPANET standard. ARPA funding for both the Super Foonly and the new operating system was cut in 1974. Most of the design team went to DEC and contributed greatly to the design of the PDP-10 model KL10. 2. The name of the company formed by Dave Poole, one of the principal Super Foonly designers, and one of hackerdom's more colorful personalities. Many people remember the parrot which sat on Poole's shoulder and was a regular companion. 3. Any of the machines built by Poole's company. The first was the F-1 (a.k.a. Super Foonly), which was the computational engine used to create the graphics in the movie "TRON". The F-1 was the fastest PDP-10 ever built, but only one was ever made. The effort drained Foonly of its financial resources, and the company turned towards building smaller, slower, and much less expensive machines. Unfortunately, these ran not the popular TOPS-20 but a TENEX variant called Foonex; this seriously limited their market. Also, the machines shipped were actually wire-wrapped engineering prototypes requiring individual attention from more than usually competent site personnel, and thus had significant reliability problems. Poole's legendary temper and unwillingness to suffer fools gladly did not help matters. By the time of the Jupiter project cancellation in 1983, Foonly's proposal to build another F-1 was eclipsed by the Mars, and the company never quite recovered. See the Mars entry for the continuation and moral of this story.
Node:footprint, Next:for free, Previous:Foonly, Up:= F =
footprint n.
1. The floor or desk area taken up by a piece of hardware. 2. [IBM] The audit trail (if any) left by a crashed program (often in plural, `footprints'). See also toeprint. 3. RAM footprint: The minimum amount of RAM which an OS or other program takes; this figure gives one an idea of how much will be left for other applications. How actively this RAM is used is another matter entirely. Recent tendencies to featuritis and software bloat can expand the RAM footprint of an OS to the point of making it nearly unusable in practice. [This problem is, thankfully, limited to operating systems so stupid that they don't do virtual memory - ESR]
Node:for free, Next:for the rest of us, Previous:footprint, Up:= F =
for free adj.
[common] Said of a capability of a programming language or hardware that is available by its design without needing cleverness to implement: "In APL, we get the matrix operations for free." "And owing to the way revisions are stored in this system, you get revision trees for free." The term usually refers to a serendipitous feature of doing things a certain way (compare big win), but it may refer to an intentional but secondary feature.
Node:for the rest of us, Next:for values of, Previous:for free, Up:= F =
for the rest of us adj.
[from the Mac slogan "The computer for the rest of us"] 1. Used to describe a spiffy product whose affordability shames other comparable products, or (more often) used sarcastically to describe spiffy but very overpriced products. 2. Describes a program with a limited interface, deliberately limited capabilities, non-orthogonality, inability to compose primitives, or any other limitation designed to not `confuse' a naive user. This places an upper bound on how far that user can go before the program begins to get in the way of the task instead of helping accomplish it. Used in reference to Macintosh software which doesn't provide obvious capabilities because it is thought that the poor lusers might not be able to handle them. Becomes `the rest of them' when used in third-party reference; thus, "Yes, it is an attractive program, but it's designed for The Rest Of Them" means a program that superficially looks neat but has no depth beyond the surface flash. See also WIMP environment, Macintrash, point-and-drool interface, user-friendly.
Node:for values of, Next:fora, Previous:for the rest of us, Up:= F =
for values of
[MIT] A common rhetorical maneuver at MIT is to use any of the canonical random numbers as placeholders for variables. "The max function takes 42 arguments, for arbitrary values of 42." "There are 69 ways to leave your lover, for 69 = 50." This is especially likely when the speaker has uttered a random number and realizes that it was not recognized as such, but even `non-random' numbers are occasionally used in this fashion. A related joke is that pi equals 3 -- for small values of pi and large values of 3.
Historical note: at MIT this usage has traditionally been traced to the programming language MAD (Michigan Algorithm Decoder), an Algol-58-like language that was the most common choice among mainstream (non-hacker) users at MIT in the mid-60s. It inherited from Algol-58 a control structure FOR VALUES OF X = 3, 7, 99 DO ... that would repeat the indicated instructions for each value in the list (unlike the usual FOR that only works for arithmetic sequences of values). MAD is long extinct, but similar for-constructs still flourish (e.g., in Unix's shell languages).
Node:fora, Next:foreground, Previous:for values of, Up:= F =
fora pl.n.
Plural of forum.
Node:foreground, Next:fork, Previous:fora, Up:= F =
foreground vt.
[Unix; common] To bring a task to the top of one's stack for immediate processing, and hackers often use it in this sense for non-computer tasks. "If your presentation is due next week, I guess I'd better foreground writing up the design document."
Technically, on a time-sharing system, a task executing in foreground is one able to accept input from and return output to the user; oppose background. Nowadays this term is primarily associated with Unix, but it appears first to have been used in this sense on OS/360. Normally, there is only one foreground task per terminal (or terminal window); having multiple processes simultaneously reading the keyboard is a good way to lose.
Node:fork, Next:fork bomb, Previous:foreground, Up:= F =
fork
In the open-source community, a fork is what occurs when two (or more) versions of a software package's source code are being developed in parallel which once shared a common code base, and these multiple versions of the source code have irreconcilable differences between them. This should not be confused with a development branch, which may later be folded back into the original source code base. Nor should it be confused with what happens when a new distribution of Linux or some other distribution is created, because that largely assembles pieces than can and will be used in other distributions without conflict.
Forking is uncommon; in fact, it is so uncommon that individual instances loom large in hacker folklore. Notable in this class were the GCC/EGCS fork (later healed by a merger) and the forks among the FreeBSD, NetBSD, and OpenBSD operating systems.
Node:fork bomb, Next:forked, Previous:fork, Up:= F =
fork bomb n.
[Unix] A particular species of wabbit that can be written in one line of C (main() {for(;;)fork();}) or shell ($0 & $0 &) on any Unix system, or occasionally created by an egregious coding bug. A fork bomb process `explodes' by recursively spawning copies of itself (using the Unix system call fork(2)). Eventually it eats all the process table entries and effectively wedges the system. Fortunately, fork bombs are relatively easy to spot and kill, so creating one deliberately seldom accomplishes more than to bring the just wrath of the gods down upon the perpetrator. See also logic bomb.
Node:forked, Next:Fortrash, Previous:fork bomb, Up:= F =
forked adj.,vi.
1. [common after 1997, esp. in the Linux community] An open-source software project is said to have forked or be forked when the project group fissions into two or more parts pursuing separate lines of development (or, less commonly, when a third party unconnected to the project group ). Forking is considered a Bad Thing - not merely because it implies a lot of wasted effort in the future, but because forks tend to be accompanied by a great deal of strife and acrimony between the successor groups over issues of legitimacy, succession, and design direction. There is serious social pressure against forking. As a result, major forks (such as the Gnu-Emacs/XEmacs split, the fissionings of the 386BSD group into three daughter project, and the short-lived GCC/EGCS split) are rare enough that they are remembered individually in hacker folklore. 2. [Unix; uncommon; prob. influenced by a mainstream expletive] Terminally slow, or dead. Originated when one system was slowed to a snail's pace by an inadvertent fork bomb.
Node:Fortrash, Next:fortune cookie, Previous:forked, Up:= F =
Fortrash /for'trash/ n.
Hackerism for the FORTRAN (FORmula TRANslator) language, referring to its primitive design, gross and irregular syntax, limited control constructs, and slippery, exception-filled semantics.
Node:fortune cookie, Next:forum, Previous:Fortrash, Up:= F =
fortune cookie n.
[WAITS, via Unix; common] A random quote, item of trivia, joke, or maxim printed to the user's tty at login time or (less commonly) at logout time. Items from this lexicon have often been used as fortune cookies. See cookie file.
Node:forum, Next:fossil, Previous:fortune cookie, Up:= F =
forum n.
[Usenet, GEnie, CI$; pl. `fora' or `forums'] Any discussion group accessible through a dial-in BBS, a mailing list, or a newsgroup (see the network). A forum functions much like a bulletin board; users submit postings for all to read and discussion ensues. Contrast real-time chat via talk mode or point-to-point personal email.
Node:fossil, Next:four-color glossies, Previous:forum, Up:= F =
fossil n.
1. In software, a misfeature that becomes understandable only in historical context, as a remnant of times past retained so as not to break compatibility. Example: the retention of octal as default base for string escapes in C, in spite of the better match of hexadecimal to ASCII and modern byte-addressable architectures. See dusty deck. 2. More restrictively, a feature with past but no present utility. Example: the force-all-caps (LCASE) bits in the V7 and BSD Unix tty driver, designed for use with monocase terminals. (In a perversion of the usual backward-compatibility goal, this functionality has actually been expanded and renamed in some later USG Unix releases as the IUCLC and OLCUC bits.) 3. The FOSSIL (Fido/Opus/Seadog Standard Interface Level) driver specification for serial-port access to replace the brain-dead routines in the IBM PC ROMs. Fossils are used by most MS-DOS BBS software in preference to the `supported' ROM routines, which do not support interrupt-driven operation or setting speeds above 9600; the use of a semistandard FOSSIL library is preferable to the bare metal serial port programming otherwise required. Since the FOSSIL specification allows additional functionality to be hooked in, drivers that use the hook but do not provide serial-port access themselves are named with a modifier, as in `video fossil'.
Node:four-color glossies, Next:frag, Previous:fossil, Up:= F =
four-color glossies n.
1. Literature created by marketroids that allegedly contains technical specs but which is in fact as superficial as possible without being totally content-free. "Forget the four-color glossies, give me the tech ref manuals." Often applied as an indication of superficiality even when the material is printed on ordinary paper in black and white. Four-color-glossy manuals are never useful for solving a problem. 2. [rare] Applied by extension to manual pages that don't contain enough information to diagnose why the program doesn't produce the expected or desired output.
Node:frag, Next:fragile, Previous:four-color glossies, Up:= F =
frag n.,v.
[from Vietnam-era U.S. military slang via the games Doom and Quake] 1. To kill another player's avatar in a multiuser game. "I hold the office Quake record with 40 frags." 2. To completely ruin something. "Forget that power supply, the lightning strike fragged it. See also gib.
Node:fragile, Next:fred, Previous:frag, Up:= F =
fragile adj.
Syn brittle.
Node:fred, Next:Fred Foobar, Previous:fragile, Up:= F =
fred n.
1. The personal name most frequently used as a metasyntactic variable (see foo). Allegedly popular because it's easy for a non-touch-typist to type on a standard QWERTY keyboard. In Great Britain, `fred', `jim' and `sheila' are common metasyntactic variables because their uppercase versions were official names given to the 3 memory areas that held I/O status registers on the lovingly-remembered BBC Microcomputer! (It is reported that SHEILA was poked the most often.) Unlike J. Random Hacker or `J. Random Loser', the name `fred' has no positive or negative loading (but see Dr. Fred Mbogo). See also barney. 2. An acronym for `Flipping Ridiculous Electronic Device'; other F-verbs may be substituted for `flipping'.
Node:Fred Foobar, Next:frednet, Previous:fred, Up:= F =
Fred Foobar n.
J. Random Hacker's cousin. Any typical human being, more or less synomous with `someone' except that Fred Foobar can be backreferenced by name later on. "So Fred Foobar will enter his phone number into the database, and it'll be archived with the others. Months later, when Fred searches..." See also Bloggs Family and Dr. Fred Mbogo
Node:frednet, Next:free software, Previous:Fred Foobar, Up:= F =

Used to refer to some random and uncommon protocol encountered on a network. "We're implementing bridging in our router to solve the frednet problem."
Node:free software, Next:freeware, Previous:frednet, Up:= F =
free software n.
As defined by Richard M. Stallman and used by the Free Software movement, this means software that gives users enough freedom to be used by the free software community. Specifically, users must be free to modify the software for their private use, and free to redistribute it either with or without modifications, either commercially or noncommercially, either gratis or charging a distribution fee. Free software has existed since the dawn of computing; Free Software as a movement began in 1984 with the GNU Project. See also open source.
Node:freeware, Next:freeze, Previous:free software, Up:= F =
freeware n.
[common] Free software, often written by enthusiasts and distributed by users' groups, or via electronic mail, local bulletin boards, Usenet, or other electronic media. At one time, `freeware' was a trademark of Andrew Fluegelman, the author of the well-known MS-DOS comm program PC-TALK III. It wasn't enforced after his mysterious disappearance and presumed death in 1984. See shareware, FRS.
Node:freeze, Next:fried, Previous:freeware, Up:= F =
freeze v.
To lock an evolving software distribution or document against changes so it can be released with some hope of stability. Carries the strong implication that the item in question will `unfreeze' at some future date. "OK, fix that bug and we'll freeze for release."
There are more specific constructions on this term. A `feature freeze', for example, locks out modifications intended to introduce new features but still allows bugfixes and completion of existing features; a `code freeze' connotes no more changes at all. At Sun Microsystems and elsewhere, one may also hear references to `code slush' -- that is, an almost-but-not-quite frozen state.
Node:fried, Next:frink, Previous:freeze, Up:= F =
fried adj.
1. [common] Non-working due to hardware failure; burnt out. Especially used of hardware brought down by a `power glitch' (see glitch), drop-outs, a short, or some other electrical event. (Sometimes this literally happens to electronic circuits! In particular, resistors can burn out and transformers can melt down, emitting noxious smoke -- see friode, SED and LER. However, this term is also used metaphorically.) Compare frotzed. 2. [common] Of people, exhausted. Said particularly of those who continue to work in such a state. Often used as an explanation or excuse. "Yeah, I know that fix destroyed the file system, but I was fried when I put it in." Esp. common in conjunction with `brain': "My brain is fried today, I'm very short on sleep."
Node:frink, Next:friode, Previous:fried, Up:= F =
frink /frink/ v.
The unknown ur-verb, fill in your own meaning. Found esp. on the Usenet newsgroup _alt.fan.lemurs_, where it is said that the lemurs know what `frink' means, but they aren't telling. Compare gorets.
Node:friode, Next:fritterware, Previous:frink, Up:= F =
friode /fri:'ohd/ n.
[TMRC] A reversible (that is, fused or blown) diode. Compare fried; see also SED, LER.
Node:fritterware, Next:frob, Previous:friode, Up:= F =
fritterware n.
An excess of capability that serves no productive end. The canonical example is font-diddling software on the Mac (see macdink); the term describes anything that eats huge amounts of time for quite marginal gains in function but seduces people into using it anyway. See also window shopping.
Node:frob, Next:frobnicate, Previous:fritterware, Up:= F =
frob /frob/ 1. n.
[MIT; very common] The TMRC definition was "FROB = a protruding arm or trunnion"; by metaphoric extension, a `frob' is any random small thing; an object that you can comfortably hold in one hand; something you can frob (sense 2). See frobnitz. 2. vt. Abbreviated form of frobnicate. 3. [from the MUD world] A command on some MUDs that changes a player's experience level (this can be used to make wizards); also, to request wizard privileges on the `professional courtesy' grounds that one is a wizard elsewhere. The command is actually `frobnicate' but is universally abbreviated to the shorter form.
Node:frobnicate, Next:frobnitz, Previous:frob, Up:= F =
frobnicate /frob'ni-kayt/ vt.
[Poss. derived from frobnitz, and usually abbreviated to frob, but `frobnicate' is recognized as the official full form.] To manipulate or adjust, to tweak. One frequently frobs bits or other 2-state devices. Thus: "Please frob the light switch" (that is, flip it), but also "Stop frobbing that clasp; you'll break it". One also sees the construction `to frob a frob'. See tweak and twiddle.
Usage: frob, twiddle, and tweak sometimes connote points along a continuum. `Frob' connotes aimless manipulation; `twiddle' connotes gross manipulation, often a coarse search for a proper setting; `tweak' connotes fine-tuning. If someone is turning a knob on an oscilloscope, then if he's carefully adjusting it, he is probably tweaking it; if he is just turning it but looking at the screen, he is probably twiddling it; but if he's just doing it because turning a knob is fun, he's frobbing it. The variant `frobnosticate' has been recently reported.
Node:frobnitz, Next:frog, Previous:frobnicate, Up:= F =
frobnitz /frob'nits/, pl. `frobnitzem' /frob'nit-zm/ or `frobni' /frob'ni:/ n.
[TMRC] An unspecified physical object, a widget. Also refers to electronic black boxes. This rare form is usually abbreviated to `frotz', or more commonly to frob. Also used are `frobnule' (/frob'n[y]ool/) and `frobule' (/frob'yool/). Starting perhaps in 1979, `frobozz' /fr*-boz'/ (plural: `frobbotzim' /fr*-bot'zm/) has also become very popular, largely through its exposure as a name via Zork. These variants can also be applied to nonphysical objects, such as data structures.
Pete Samson, compiler of the original TMRC lexicon, adds, "Under the TMRC [railroad] layout were many storage boxes, managed (in 1958) by David R. Sawyer. Several had fanciful designations written on them, such as `Frobnitz Coil Oil'. Perhaps DRS intended Frobnitz to be a proper name, but the name was quickly taken for the thing". This was almost certainly the origin of the term.
Node:frog, Next:frogging, Previous:frobnitz, Up:= F =

1. interj. Term of disgust (we seem to have a lot of them). 2. Used as a name for just about anything. See foo. 3. n. Of things, a crock. 4. n. Of people, somewhere in between a turkey and a toad. 5. `froggy': adj. Similar to bagbiting, but milder. "This froggy program is taking forever to run!"
Node:frogging, Next:front end, Previous:frog, Up:= F =
frogging [University of Waterloo] v.
1. Partial corruption of a text file or input stream by some bug or consistent glitch, as opposed to random events like line noise or media failures. Might occur, for example, if one bit of each incoming character on a tty were stuck, so that some characters were correct and others were not. See terminak for a historical example and compare dread high-bit disease. 2. By extension, accidental display of text in a mode where the output device emits special symbols or mnemonics rather than conventional ASCII. This often happens, for example, when using a terminal or comm program on a device like an IBM PC with a special `high-half' character set and with the bit-parity assumption wrong. A hacker sufficiently familiar with ASCII bit patterns might be able to read the display anyway.
Node:front end, Next:frotz, Previous:frogging, Up:= F =
front end n.
1. An intermediary computer that does set-up and filtering for another (usually more powerful but less friendly) machine (a `back end'). 2. What you're talking to when you have a conversation with someone who is making replies without paying attention. "Look at the dancing elephants!" "Uh-huh." "Do you know what I just said?" "Sorry, you were talking to the front end." 3. Software that provides an interface to another program `behind' it, which may not be as user-friendly. Probably from analogy with hardware front-ends (see sense 1) that interfaced with mainframes.
