The Hacker's Dictionary by - (sneezy the snowman read aloud txt) 📕

miswarts might be clarified by the following hypothetical exchange between two hackers on an airliner:

A: "This seat doesn't recline."

B: "That's not a bug, that's a feature. There is an emergency exit door built around the window behind you, and the route has to be kept clear."

A: "Oh. Then it's a misfeature; they should have increased the spacing between rows here."

B: "Yes. But if they'd increased spacing in only one section it would have been a wart --- they would've had to make nonstandard-length ceiling panels to fit over the displaced seats."

A: "A miswart, actually. If they increased spacing throughout they'd lose several rows and a chunk out of the profit margin. So unequal spacing would actually be the Right Thing."

B: "Indeed."

`Undocumented feature' is a common, allegedly humorous euphemism for a {bug}.

:feature creature: [poss. fr. slang `creature feature' for a horror movie] n. 1. One who loves to add features to designs or programs, perhaps at the expense of coherence, concision, or {taste}. 2. Alternately, a semi-mythical being that induces otherwise rational programmers to perpetrate such crocks. See also {feeping creaturism}, {creeping featurism}.

:feature key: n. The Macintosh key with the cloverleaf graphic on its keytop; sometimes referred to as flower',pretzel', clover',propeller', beanie' (an apparent reference to the major feature of a propeller beanie), {splat}, or thecommand key'. The Mac's equivalent of an {alt} key. The proliferation of terms for this creature may illustrate one subtle peril of iconic interfaces.

Many people have been mystified by the cloverleaf-like symbol that appears on the feature key. Its oldest name is `cross of St.

Hannes', but it occurs in pre-Christian Viking art as a decorative motif. Throughout Scandinavia today the road agencies use it to mark sites of historical interest. Many of these are old churches; hence, the Swedish idiom for the symbol is kyrka', cognate to Englishchurch' and Scots-dialect `kirk' but pronounced /shir'k*/ in modern Swedish. This is in fact where Apple got the symbol; they give the translation "interesting feature"!

:feature shock: [from Alvin Toffler's book title `Future Shock'] n. A user's (or programmer's!) confusion when confronted with a package that has too many features and poor introductory material.

:featurectomy: /feech*r-ek't*-mee/ n. The act of removing a feature from a program. Featurectomies come in two flavors, therighteous' and the `reluctant'. Righteous featurectomies are performed because the remover believes the program would be more elegant without the feature, or there is already an equivalent and better way to achieve the same end. (This is not quite the same thing as removing a {misfeature}.) Reluctant featurectomies are performed to satisfy some external constraint such as code size or execution speed.

:feep: /feep/ 1. n. The soft electronic bell' sound of a display terminal (except for a VT-52); a beep (in fact, the microcomputer world seems to prefer {beep}). 2. vi. To cause the display to make a feep sound. ASR-33s (the original TTYs) do not feep; they have mechanical bells that ring. Alternate forms: {beep},bleep', or just about anything suitably onomatopoeic. (Jeff MacNelly, in his comic strip "Shoe", uses the word eep' for sounds made by computer terminals and video games; this is perhaps the closest written approximation yet.) The termbreedle' was sometimes heard at SAIL, where the terminal bleepers are not particularly soft (they sound more like the musical equivalent of a raspberry or Bronx cheer; for a close approximation, imagine the sound of a Star Trek communicator's beep lasting for 5 seconds). The `feeper' on a VT-52 has been compared to the sound of a '52 Chevy stripping its gears. See also {ding}.

:feeper: /fee'pr/ n. The device in a terminal or workstation (usually a loudspeaker of some kind) that makes the {feep} sound.

:feeping creature: [from {feeping creaturism}] n. An unnecessary feature; a bit of {chrome} that, in the speaker's judgment, is the camel's nose for a whole horde of new features.

:feeping creaturism: /fee'ping kree`ch*r-izm/ n. A deliberate spoonerism for {creeping featurism}, meant to imply that the system or program in question has become a misshapen creature of hacks. This term isn't really well defined, but it sounds so neat that most hackers have said or heard it. It is probably reinforced by an image of terminals prowling about in the dark making their customary noises.

:feetch feetch: /feech feech/ interj. If someone tells you about some new improvement to a program, you might respond: "Feetch, feetch!" The meaning of this depends critically on vocal inflection. With enthusiasm, it means something like "Boy, that's great! What a great hack!" Grudgingly or with obvious doubt, it means "I don't know; it sounds like just one more unnecessary and complicated thing". With a tone of resignation, it means, "Well, I'd rather keep it simple, but I suppose it has to be done".

:fence: n. 1. A sequence of one or more distinguished ({out-of-band}) characters (or other data items), used to delimit a piece of data intended to be treated as a unit (the computer-science literature calls this a `sentinel'). The NUL

(ASCII 0000000) character that terminates strings in C is a fence.

Hex FF is also (though slightly less frequently) used this way.

See {zigamorph}. 2. [among users of optimizing compilers] Any technique, usually exploiting knowledge about the compiler, that blocks certain optimizations. Used when explicit mechanisms are not available or are overkill. Typically a hack: "I call a dummy procedure there to force a flush of the optimizer's register-coloring info" can be expressed by the shorter "That's a fence procedure".

:fencepost error: n. 1. A problem with the discrete equivalent of a boundary condition. Often exhibited in programs by iterative loops. From the following problem: "If you build a fence 100 feet long with posts 10 feet apart, how many posts do you need?"

Either 9 or 11 is a better answer than the obvious 10. For example, suppose you have a long list or array of items, and want to process items m through n; how many items are there? The obvious answer is n - m, but that is off by one; the right answer is n - m + 1. A program that used the `obvious'

formula would have a fencepost error in it. See also {zeroth}

and {off-by-one error}, and note that not all off-by-one errors are fencepost errors. The game of Musical Chairs involves a catastrophic off-by-one error where N people try to sit in N - 1 chairs, but it's not a fencepost error. Fencepost errors come from counting things rather than the spaces between them, or vice versa, or by neglecting to consider whether one should count one or both ends of a row. 2. Occasionally, an error induced by unexpectedly regular spacing of inputs, which can (for instance) screw up your hash table.

:fepped out: /fept owt/ adj. The Symbolics 3600 Lisp Machine has a Front-End Processor called a `FEP' (compare sense 2 of {box}).

When the main processor gets {wedged}, the FEP takes control of the keyboard and screen. Such a machine is said to have `fepped out'.

:FidoNet: n. A worldwide hobbyist network of personal computers which exchange mail, discussion groups, and files. Founded in 1984

and originally consisting only of IBM PCs and compatibles, FidoNet now includes such diverse machines as Apple ][s, Ataris, Amigas, and UNIX systems. Though it is much younger than {USENET}, FidoNet is already (in early 1991) a significant fraction of USENET's size at some 8000 systems.

:field circus: [a derogatory pun on `field service'] n. The field service organization of any hardware manufacturer, but especially DEC. There is an entire genre of jokes about DEC field circus engineers:

Q: How can you recognize a DEC field circus engineer with a flat tire? A: He's changing one tire at a time to see which one is flat. Q: How can you recognize a DEC field circus engineer who is out of gas? A: He's changing one tire at a time to see which one is flat.

[See {Easter egging} for additional insight on these jokes.]

There is also the `Field Circus Cheer' (from the {plan file} for DEC on MIT-AI):

Maynard! Maynard! Don't mess with us! We're mean and we're tough! If you get us confused We'll screw up your stuff.

(DEC's service HQ is located in Maynard, Massachusetts.) :field servoid: [play on `android'] /fee'ld ser'voyd/ n.

Representative of a field service organization (see {field circus}). This has many of the implications of {droid}.

:Fight-o-net: [FidoNet] n. Deliberate distortion of {FidoNet}, often applied after a flurry of {flamage} in a particular {echo}, especially the SYSOP echo or Fidonews (see {'Snooze}).

:File Attach: [FidoNet] 1. n. A file sent along with a mail message from one BBS to another. 2. vt. Sending someone a file by using the File Attach option in a BBS mailer.

:File Request: [FidoNet] 1. n. The {FidoNet} equivalent of {FTP}, in which one BBS system automatically dials another and {snarf}s one or more files. Often abbreviated `FReq'; files are often announced as being "available for FReq" in the same way that files are announced as being "available for/by anonymous FTP" on the Internet. 2. vt. The act of getting a copy of a file by using the File Request option of the BBS mailer.

:file signature: n. A {magic number} sense 3.

:filk: /filk/ [from SF fandom, where a typo for folk' was adopted as a new word] n.,v.
