Chapter III: Front Matter (3)

Short for `application program', as opposed to a systems program. Apps are what systems vendors are forever chasing developers to create for their environments so they can sell more boxes. Hackers tend not to think of the things they themselves run as apps; thus, in hacker parlance the term excludes compilers, program editors, games, and messaging systems, though a user would consider all those to be apps. (Broadly, an app is often a self-contained environment for performing some well-defined task such as `word processing'; hackers tend to prefer more general-purpose tools.) See killer app; oppose tool, operating system.

Node:arena, Next:arg, Previous:app, Up:= A =

arena n.

[common; Unix] The area of memory attached to a process by brk(2) and sbrk(2) and used by malloc(3) as dynamic storage. So named from a malloc: corrupt arena message emitted when some early versions detected an impossible value in the free block list. See overrun screw, aliasing bug, memory leak, memory smash, smash the stack.

Node:arg, Next:ARMM, Previous:arena, Up:= A =

arg /arg/ n.

Abbreviation for `argument' (to a function), used so often as to have become a new word (like `piano' from `pianoforte'). "The sine function takes 1 arg, but the arc-tangent function can take either 1 or 2 args." Compare param, parm, var.

Node:ARMM, Next:armor-plated, Previous:arg, Up:= A =

ARMM n.

[acronym, `Automated Retroactive Minimal Moderation'] A Usenet cancelbot created by Dick Depew of Munroe Falls, Ohio. ARMM was intended to automatically cancel posts from anonymous-posting sites. Unfortunately, the robot's recognizer for anonymous postings triggered on its own automatically-generated control messages! Transformed by this stroke of programming ineptitude into a monster of Frankensteinian proportions, it broke loose on the night of March 31, 1993 and proceeded to spam _news.admin.policy_ with a recursive explosion of over 200 messages.

ARMM's bug produced a recursive cascade of messages each of which mechanically added text to the ID and Subject and some other headers of its parent. This produced a flood of messages in which each header took up several screens and each message ID and subject line got longer and longer and longer.

Reactions varied from amusement to outrage. The pathological messages crashed at least one mail system, and upset people paying line charges for their Usenet feeds. One poster described the ARMM debacle as "instant Usenet history" (also establishing the term despew), and it has since been widely cited as a cautionary example of the havoc the combination of good intentions and incompetence can wreak on a network. Compare Great Worm; sorcerer's apprentice mode. See also software laser, network meltdown.

Node:asbestos, Next:asbestos cork award, Previous:armor-plated, Up:= A =

asbestos adj.

[common] Used as a modifier to anything intended to protect one from flames; also in other highly flame-suggestive usages. See, for example, asbestos longjohns and asbestos cork award.

Node:asbestos cork award, Next:asbestos longjohns, Previous:asbestos, Up:= A =

asbestos cork award n.

Once, long ago at MIT, there was a flamer so consistently obnoxious that another hacker designed, had made, and distributed posters announcing that said flamer had been nominated for the `asbestos cork award'. (Any reader in doubt as to the intended application of the cork should consult the etymology under flame.) Since then, it is agreed that only a select few have risen to the heights of bombast required to earn this dubious dignity -- but there is no agreement on which few.

Node:asbestos longjohns, Next:ASCII, Previous:asbestos cork award, Up:= A =

Notional garments donned by Usenet posters just before emitting a remark they expect will elicit flamage. This is the most common of the asbestos coinages. Also `asbestos underwear', `asbestos overcoat', etc.

ASCII /as'kee/ n.

[originally an acronym (American Standard Code for Information Interchange) but now merely conventional] The predominant character set encoding of present-day computers. The standard version uses 7 bits for each character, whereas most earlier codes (including early drafts of of ASCII prior to June 1961) used fewer. This change allowed the inclusion of lowercase letters -- a major win -- but it did not provide for accented letters or any other letterforms not used in English (such as the German sharp-S or the ae-ligature which is a letter in, for example, Norwegian). It could be worse, though. It could be much worse. See EBCDIC to understand how. A history of ASCII and its ancestors is at http://www.wps.com/texts/codes/index.html.

Computers are much pickier and less flexible about spelling than humans; thus, hackers need to be very precise when talking about characters, and have developed a considerable amount of verbal shorthand for them. Every character has one or more names -- some formal, some concise, some silly. Common jargon names for ASCII characters are collected here. See also individual entries for bang, excl, open, ques, semi, shriek, splat, twiddle, and Yu-Shiang Whole Fish.

This list derives from revision 2.3 of the Usenet ASCII pronunciation guide. Single characters are listed in ASCII order; character pairs are sorted in by first member. For each character, common names are given in rough order of popularity, followed by names that are reported but rarely seen; official ANSI/CCITT names are surrounded by brokets: <>. Square brackets mark the particularly silly names introduced by INTERCAL. The abbreviations "l/r" and "o/c" stand for left/right and "open/close" respectively. Ordinary parentheticals provide some usage information.

Common: <tilde>; squiggle; twiddle; not. Rare: approx; wiggle; swung dash; enyay; [sqiggle (sic)].

The pronunciation of # as `pound' is common in the U.S. but a bad idea; Commonwealth Hackish has its own, rather more apposite use of `pound sign' (confusingly, on British keyboards the pound graphic happens to replace #; thus Britishers sometimes call # on a U.S.-ASCII keyboard `pound', compounding the American error). The U.S. usage derives from an old-fashioned commercial practice of using a # suffix to tag pound weights on bills of lading. The character is usually pronounced `hash' outside the U.S. There are more culture wars over the correct pronunciation of this character than any other, which has led to the ha ha only serious suggestion that it be pronounced `shibboleth' (see Judges 12:6 in an Old Testament or Tanakh).

The `uparrow' name for circumflex and `leftarrow' name for underline are historical relics from archaic ASCII (the 1963 version), which had these graphics in those character positions rather than the modern punctuation characters.

The `swung dash' or `approximation' sign is not quite the same as tilde in typeset material but the ASCII tilde serves for both (compare angle brackets).

Some other common usages cause odd overlaps. The #, $, >, and & characters, for example, are all pronounced "hex" in different communities because various assemblers use them as a prefix tag for hexadecimal constants (in particular, # in many assembler-programming cultures, $ in the 6502 world, > at Texas Instruments, and & on the BBC Micro, Sinclair, and some Z80 machines). See also splat.

The inability of ASCII text to correctly represent any of the world's other major languages makes the designers' choice of 7 bits look more and more like a serious misfeature as the use of international networks continues to increase (see software rot). Hardware and software from the U.S. still tends to embody the assumption that ASCII is the universal character set and that characters have 7 bits; this is a major irritant to people who want to use a character set suited to their own languages. Perversely, though, efforts to solve this problem by proliferating `national' character sets produce an evolutionary pressure to use a smaller subset common to all those in use.

Node:ASCIIbetical order, Next:astroturfing, Previous:ASCII art, Up:= A =

ASCIIbetical order /as'kee-be'-t*-kl or'dr/ adj.,n.

Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. This lexicon is sorted in something close to ASCIIbetical order, but with case ignored and entries beginning with non-alphabetic characters moved to the end. "At my video store, they used their computer to sort the videos into ASCIIbetical order, so I couldn't find `"Crocodile" Dundee' until I thought to look before `2001' and `48 HRS.'!"

Node:astroturfing, Next:atomic, Previous:ASCIIbetical order, Up:= A =

astroturfing n.

The use of paid shills to create the impression of a popular movement, through means like letters to newspapers from soi-disant `concerned citizens', paid opinion pieces, and the formation of grass-roots lobbying groups that are actually funded by a PR group (astroturf is fake grass; hence the term). This term became common among hackers after it came to light in early 1998 that Microsoft had attempted to use such tactics to forestall the U.S. Department of Justice's antitrust action against the company.

This backfired horribly, angering a number of state attorneys-general enough to induce them to go public with plans to join the Federal suit. It also set anybody defending Microsoft on the net for the accusation "You're just astroturfing!".

Node:atomic, Next:attoparsec, Previous:astroturfing, Up:= A =

atomic adj.

[from Gk. `atomos', indivisible] 1. Indivisible; cannot be split up. For example, an instruction may be said to do several things `atomically', i.e., all the things are done immediately, and there is no chance of the instruction being half-completed or of another being interspersed. Used esp. to convey that an operation cannot be screwed up by interrupts. "This routine locks the file and increments the file's semaphore atomically." 2. [primarily techspeak] Guaranteed to complete successfully or not at all, usu. refers to database transactions. If an error prevents a partially-performed transaction from proceeding to completion, it must be "backed out," as the database must not be left in an inconsistent state.

Computer usage, in either of the above senses, has none of the connotations that `atomic' has in mainstream English (i.e. of particles of matter, nuclear explosions etc.).

Node:attoparsec, Next:AUP, Previous:atomic, Up:= A =

attoparsec n.

About an inch. `atto-' is the standard SI prefix for multiplication by 10^(-18). A parsec (parallax-second) is 3.26 light-years; an attoparsec is thus 3.26 * 10^(-18) light years, or about 3.1 cm (thus, 1 attoparsec/microfortnight equals about 1 inch/sec). This unit is reported to be in use (though probably not very seriously) among hackers in the U.K. See micro-.

Node:AUP, Next:autobogotiphobia, Previous:attoparsec, Up:= A =

AUP /A-U-P/

Abbreviation, "Acceptable Use Policy". The policy of a given ISP which sets out what the ISP considers to be (un)acceptable uses of its Internet resources.

n. See bogotify.

Node:automagically, Next:avatar, Previous:autobogotiphobia, Up:= A =

automagically /aw-toh-maj'i-klee/ adv.

Automatically, but in a way that, for some reason (typically because it is too complicated, or too ugly, or perhaps even too trivial), the speaker doesn't feel like explaining to you. See magic. "The C-INTERCAL compiler generates C, then automagically invokes cc(1) to produce an executable."

This term is quite old, going back at least to the mid-70s in jargon and probably much earlier. The word `automagic' occurred in advertising (for a shirt-ironing gadget) as far back as the late 1940s.

Node:avatar, Next:awk, Previous:automagically, Up:= A =

avatar n. Syn.

[in Hindu mythology, the incarnation of a god] 1. Among people working on virtual reality and cyberspace interfaces, an avatar is an icon or representation of a user in a shared virtual reality. The term is sometimes used on MUDs. 2. [CMU, Tektronix] root, superuser. There are quite a few Unix machines on which the name of the superuser account is `avatar' rather than `root'. This quirk was originated by a CMU hacker who found the terms `root' and `superuser' unimaginative, and thought `avatar' might better impress people with the responsibility they were accepting.

Node:awk, Next:B5, Previous:avatar, Up:= A =

awk /awk/

1. n. [Unix techspeak] An interpreted language for massaging text data developed by Alfred Aho, Peter Weinberger, and Brian Kernighan (the name derives from their initials). It is characterized by C-like syntax, a declaration-free approach to variable typing and declarations, associative arrays, and field-oriented text processing. See also Perl. 2. n. Editing term for an expression awkward to manipulate through normal regexp facilities (for example, one containing a newline). 3. vt. To process data using awk(1).

[common] Abbreviation for "Babylon 5", a science-fiction TV series as revered among hackers as was the original Star Trek.

Node:back door, Next:backbone cabal, Previous:B5, Up:= B =

back door n.

[common] A hole in the security of a system deliberately left in place by designers or maintainers. The motivation for such holes is not always sinister; some operating systems, for example, come out of the box with privileged accounts intended for use by field service technicians or the vendor's maintenance programmers. Syn. trap door; may also be called a `wormhole'. See also iron box, cracker, worm, logic bomb.

Historically, back doors have often lurked in systems longer than anyone expected or planned, and a few have become widely known. Ken Thompson's 1983 Turing Award lecture to the ACM admitted the existence of a back door in early Unix versions that may have qualified as the most fiendishly clever security hack of all time. In this scheme, the C compiler contained code that would recognize when the `login' command was being recompiled and insert some code recognizing a password chosen by Thompson, giving him entry to the system whether or not an account had been created for him.

Normally such a back door could be removed by removing it from the source code for the compiler and recompiling the compiler. But to recompile the compiler, you have to use the compiler -- so Thompson also arranged that the compiler would recognize when it was compiling a version of itself, and insert into the recompiled compiler the code to insert into the recompiled `login' the code to allow Thompson entry -- and, of course, the code to recognize itself and do the whole thing again the next time around! And having done this once, he was then able to recompile the compiler from the original sources; the hack perpetuated itself invisibly, leaving the back door in place and active but with no trace in the sources.

The talk that suggested this truly moby hack was published as "Reflections on Trusting Trust", "Communications of the ACM 27", 8 (August 1984), pp. 761-763 (text available at http://www.acm.org/classics). Ken Thompson has since confirmed that this hack was implemented and that the Trojan Horse code did appear in the login binary of a Unix Support group machine. Ken says the crocked compiler was never distributed. Your editor has heard two separate reports that suggest that the crocked login did make it out of Bell Labs, notably to BBN, and that it enabled at least one late-night login across the network by someone using the login name `kt'.

Node:backbone cabal, Next:backbone site, Previous:back door, Up:= B =

backbone cabal n.

A group of large-site administrators who pushed through the Great Renaming and reined in the chaos of Usenet during most of the 1980s. During most of its lifetime, the Cabal (as it was sometimes capitalized) steadfastly denied its own existence; it was almost obligatory for anyone privy to their secrets to respond "There is no Cabal" whenever the existence or activities of the group were speculated on in public.

The result of this policy was an attractive aura of mystery. Even a decade after the cabal mailing list disbanded in late 1988 following a bitter internal catfight, many people believed (or claimed to believe) that it had not actually disbanded but only gone deeper underground with its power intact.

This belief became a model for various paranoid theories about various Cabals with dark nefarious objectives beginning with taking over the Usenet or Internet. These paranoias were later satirized in ways that took on a life of their own. See Eric Conspiracy for one example.

See NANA for the subsequent history of "the Cabal".

Node:backbone site, Next:backgammon, Previous:backbone cabal, Up:= B =

backbone site n.,obs.

Formerly, a key Usenet and email site, one that processes a large amount of third-party traffic, especially if it is the home site of any of the regional coordinators for the Usenet maps. Notable backbone sites as of early 1993, when this sense of the term was beginning to pass out of general use due to wide availability of cheap Internet connections, included _uunet_ and the mail machines at Rutgers University, UC Berkeley, DEC's Western Research Laboratories, Ohio State University, and the University of Texas. Compare rib site, leaf site.

[1996 update: This term is seldom heard any more. The UUCP network world that gave it meaning has nearly disappeared; everyone is on the Internet now and network traffic is distributed in very different patterns. Today one might see references to a `backbone router' instead --ESR]

Node:backgammon, Next:background, Previous:backbone site, Up:= B =

backgammon

See bignum (sense 3), moby (sense 4), and pseudoprime.

Node:background, Next:backreference, Previous:backgammon, Up:= B =

background n.,adj.,vt.

[common] To do a task `in background' is to do it whenever foreground matters are not claiming your undivided attention, and `to background' something means to relegate it to a lower priority. "For now, we'll just print a list of nodes and links; I'm working on the graph-printing problem in background." Note that this implies ongoing activity but at a reduced level or in spare time, in contrast to mainstream `back burner' (which connotes benign neglect until some future resumption of activity). Some people prefer to use the term for processing that they have queued up for their unconscious minds (a tack that one can often fruitfully take upon encountering an obstacle in creative work). Compare amp off, slopsucker.

Technically, a task running in background is detached from the terminal where it was started (and often running at a lower priority); oppose foreground. Nowadays this term is primarily associated with Unix, but it appears to have been first used in this sense on OS/360.

Node:backreference, Next:backronym, Previous:background, Up:= B =

backreference n.

1. In a regular expression or pattern match, the text which was matched within grouping parentheses parentheses. 2. The part of the pattern which refers back to the matched text. 3. By extension, anything which refers back to something which has been seen or discussed before. "When you said `she' just now, who were you backreferencing?"

Node:backronym, Next:backspace and overstrike, Previous:backreference, Up:= B =

backronym n.

[portmanteau of back + acronym] A word interpreted as an acronym that was not originally so intended. This is a special case of what linguists call `back formation'. Examples are given under BASIC, recursive acronym (Cygnus), Acme, and mung. Discovering backronyms is a common form of wordplay among hackers. Compare retcon.

backward combatability /bak'w*rd k*m-bat'*-bil'*-tee/ n.

[CMU, Tektronix: from `backward compatibility'] A property of hardware or software revisions in which previous protocols, formats, layouts, etc. are irrevocably discarded in favor of `new and improved' protocols, formats, and layouts, leaving the previous ones not merely deprecated but actively defeated. (Too often, the old and new versions cannot definitively be distinguished, such that lingering instances of the previous ones yield crashes or other infelicitous effects, as opposed to a simple "version mismatch" message.) A backwards compatible change, on the other hand, allows old versions to coexist without crashes or error messages, but too many major changes incorporating elaborate backwards compatibility processing can lead to extreme software bloat. See also flag day.

BAD /B-A-D/ adj.

[IBM: acronym, `Broken As Designed'] Said of a program that is bogus because of bad design and misfeatures rather than because of bugginess. See working as designed.

Node:Bad and Wrong, Next:Bad Thing, Previous:BAD, Up:= B =

Bad and Wrong adj.

[Durham, UK] Said of something that is both badly designed and wrongly executed. This common term is the prototype of, and is used by contrast with, three less common terms - Bad and Right (a kludge, something ugly but functional); Good and Wrong (an overblown GUI or other attractive nuisance); and (rare praise) Good and Right. These terms entered common use at Durham c.1994 and may have been imported from elsewhere; they are also in use at Oxford, and the emphatic form "Evil, Bad and Wrong" (abbreviated EBW) is reported fromm there. There are standard abbreviations: they start with B&R, a typo for "Bad and Wrong". Consequently, B&W is actually "Bad and Right", G&R = "Good and Wrong", and G&W = "Good and Right". Compare evil and rude, Good Thing, Bad Thing.

Node:Bad Thing, Next:bag on the side, Previous:Bad and Wrong, Up:= B =

Bad Thing n.

[very common; from the 1930 Sellar & Yeatman parody "1066 And All That"] Something that can't possibly result in improvement of the subject. This term is always capitalized, as in "Replacing all of the 9600-baud modems with bicycle couriers would be a Bad Thing". Oppose Good Thing. British correspondents confirm that Bad Thing and Good Thing (and prob. therefore Right Thing and Wrong Thing) come from the book referenced in the etymology, which discusses rulers who were Good Kings but Bad Things. This has apparently created a mainstream idiom on the British side of the pond. It is very common among American hackers, but not in mainstream usage here. Compare Bad and Wrong.

bag on the side n.

[prob. originally related to a colostomy bag] An extension to an established hack that is supposed to add some functionality to the original. Usually derogatory, implying that the original was being overextended and should have been thrown away, and the new product is ugly, inelegant, or bloated. Also v. phrase, `to hang a bag on the side [of]'. "C++? That's just a bag on the side of C ...." "They want me to hang a bag on the side of the accounting system."

Node:bagbiter, Next:bagbiting, Previous:bag on the side, Up:= B =

bagbiter /bag'bi:t-*r/ n.

1. Something, such as a program or a computer, that fails to work, or works in a remarkably clumsy manner. "This text editor won't let me make a file with a line longer than 80 characters! What a bagbiter!" 2. A person who has caused you some trouble, inadvertently or otherwise, typically by failing to program the computer properly. Synonyms: loser, cretin, chomper. 3. `bite the bag' vi. To fail in some manner. "The computer keeps crashing every five minutes." "Yes, the disk controller is really biting the bag."

The original loading of these terms was almost undoubtedly obscene, possibly referring to a douche bag or the scrotum (we have reports of "Bite the douche bag!" being used as a taunt at MIT 1970-1976, and we have another report that "Bite the bag!" was in common use at least as early as 1965), but in their current usage they have become almost completely sanitized.

ITS's lexiphage program was the first and to date only known example of a program intended to be a bagbiter.

Having the quality of a bagbiter. "This bagbiting system won't let me compute the factorial of a negative number." Compare losing, cretinous, bletcherous, `barfucious' (under barfulous) and `chomping' (under chomp).

Node:baggy pantsing, Next:balloonian variable, Previous:bagbiting, Up:= B =

baggy pantsing v.

[Georgia Tech] A "baggy pantsing" is used to reprimand hackers who incautiously leave their terminals unlocked. The affected user will come back to find a post from them on internal newsgroups discussing exactly how baggy their pants are, an accepted stand-in for "unattentive user who left their work unprotected in the clusters". A properly-done baggy pantsing is highly mocking and humorous (see examples below). It is considered bad form to post a baggy pantsing to off-campus newsgroups or the more technical, serious groups. A particularly nice baggy pantsing may be "claimed" by immediately quoting the message in full, followed by your sig; this has the added benefit of keeping the embarassed victim from being able to delete the post. Interesting baggy-pantsings have been done involving adding commands to login scripts to repost the message every time the unlucky user logs in; Unix boxes on the residential network, when cracked, oftentimes have their homepages replaced (after being politely backedup to another file) with a baggy-pants message; .plan files are also occasionally targeted. Usage: "Prof. Greenlee fell asleep in the Solaris cluster again; we baggy-pantsed him to git.cc.class.2430.flame."

balloonian variable n.

[Commodore users; perh. a deliberate phonetic mangling of `boolean variable'?] Any variable that doesn't actually hold or control state, but must nevertheless be declared, checked, or set. A typical balloonian variable started out as a flag attached to some environment feature that either became obsolete or was planned but never implemented. Compatibility concerns (or politics attached to same) may require that such a flag be treated as though it were live.

Node:bamf, Next:banana label, Previous:balloonian variable, Up:= B =

bamf /bamf/

1. [from X-Men comics; originally "bampf"] interj. Notional sound made by a person or object teleporting in or out of the hearer's vicinity. Often used in virtual reality (esp. MUD) electronic fora when a character wishes to make a dramatic entrance or exit. 2. The sound of magical transformation, used in virtual reality fora like MUDs. 3. In MUD circles, "bamf" is also used to refer to the act by which a MUD server sends a special notification to the MUD client to switch its connection to another server ("I'll set up the old site to just bamf people over to our new location."). 4. Used by MUDders on occasion in a more general sense related to sense 3, to refer to directing someone to another location or resource ("A user was asking about some technobabble so I bamfed them to http://www.tuxedo.org/jargon/".)

[from the story of the little girl who said "I know how to spell `banana', but I don't know when to stop"]. Not knowing where or when to bring a production to a close (compare fencepost error). One may say `there is a banana problem' of an algorithm with poorly defined or incorrect termination conditions, or in discussing the evolution of a design that may be succumbing to featuritis (see also creeping elegance, creeping featuritis). See item 176 under HAKMEM, which describes a banana problem in a Dissociated Press implementation. Also, see one-banana problem for a superficially similar but unrelated usage.

Node:binary four, Next:bandwidth, Previous:banana problem, Up:= B =

[Usenet] The finger, in the sense of `digitus impudicus'. This comes from an analogy between binary and the hand, i.e. 1=00001=thumb, 2=00010=index finger, 3=00011=index and thumb, 4=00100. Considered silly. Prob. from humorous derivative of finger, sense 4.

Node:bandwidth, Next:bang, Previous:binary four, Up:= B =

1. [common] Used by hackers (in a generalization of its technical meaning) as the volume of information per unit time that a computer, person, or transmission medium can handle. "Those are amazing graphics, but I missed some of the detail -- not enough bandwidth, I guess." Compare low-bandwidth. This generalized usage began to go mainstream after the Internet population explosion of 1993-1994. 2. Attention span. 3. On Usenet, a measure of network capacity that is often wasted by people complaining about how items posted by others are a waste of bandwidth.

Node:bang, Next:bang on, Previous:bandwidth, Up:= B =

bang

1. n. Common spoken name for ! (ASCII 0100001), especially when used in pronouncing a bang path in spoken hackish. In elder days this was considered a CMUish usage, with MIT and Stanford hackers preferring excl or shriek; but the spread of Unix has carried `bang' with it (esp. via the term bang path) and it is now certainly the most common spoken name for !. Note that it is used exclusively for non-emphatic written !; one would not say "Congratulations bang" (except possibly for humorous purposes), but if one wanted to specify the exact characters `foo!' one would speak "Eff oh oh bang". See shriek, ASCII. 2. interj. An exclamation signifying roughly "I have achieved enlightenment!", or "The dynamite has cleared out my brain!" Often used to acknowledge that one has perpetrated a thinko immediately after one has been called on it.

Node:bang on, Next:bang path, Previous:bang, Up:= B =

bang on vt.

To stress-test a piece of hardware or software: "I banged on the new version of the simulator all day yesterday and it didn't crash once. I guess it is ready for release." The term pound on is synonymous.

Node:bang path, Next:banner, Previous:bang on, Up:= B =

bang path n.

[now historical] An old-style UUCP electronic-mail address specifying hops to get from some assumed-reachable location to the addressee, so called because each hop is signified by a bang sign. Thus, for example, the path _...!bigsite!foovax!barbox!me_ directs people to route their mail to machine _bigsite_ (presumably a well-known location accessible to everybody) and from there through the machine _foovax_ to the account of user _me_ on _barbox_.

In the bad old days of not so long ago, before autorouting mailers became commonplace, people often published compound bang addresses using the { } convention (see glob) to give paths from several big machines, in the hopes that one's correspondent might be able to get mail to one of them reliably (example: _...!{seismo, ut-sally, ihnp4}!rice!beta!gamma!me_). Bang paths of 8 to 10 hops were not uncommon in 1981. Late-night dial-up UUCP links would cause week-long transmission times. Bang paths were often selected by both transmission time and reliability, as messages would often get lost. See Internet address, the network, and sitename.

Node:banner, Next:banner ad, Previous:bang path, Up:= B =

1. The title page added to printouts by most print spoolers (see spool). Typically includes user or account ID information in very large character-graphics capitals. Also called a `burst page', because it indicates where to burst (tear apart) fanfold paper to separate one user's printout from the next. 2. A similar printout generated (typically on multiple pages of fan-fold paper) from user-specified text, e.g., by a program such as Unix's banner({1,6}). 3. On interactive software, a first screen containing a logo and/or author credits and/or a copyright notice. This is probably now the commonest sense.

[warez d00dz] A FTP site storing pirated files where one must first click on several banners and/or subscribe to various `free' services, usually generating some form of revenues for the site owner, to be able to access the site. More often than not, the username/password painfully obtained by clicking on banners and subscribing to bogus services or mailing lists turns out to be non-working or gives access to a site that always responds busy. See ratio site, leech mode.

1. [very common] The second metasyntactic variable, after foo and before baz. "Suppose we have two functions: FOO and BAR. FOO calls BAR...." 2. Often appended to foo to produce foobar.

Node:bare metal, Next:barf, Previous:bar, Up:= B =

bare metal n.

1. [common] New computer hardware, unadorned with such snares and delusions as an operating system, an HLL, or even assembler. Commonly used in the phrase `programming on the bare metal', which refers to the arduous work of bit bashing needed to create these basic tools for a new machine. Real bare-metal programming involves things like building boot proms and BIOS chips, implementing basic monitors used to test device drivers, and writing the assemblers that will be used to write the compiler back ends that will give the new machine a real development environment. 2. `Programming on the bare metal' is also used to describe a style of hand-hacking that relies on bit-level peculiarities of a particular hardware design, esp. tricks for speed and space optimization that rely on crocks such as overlapping instructions (or, as in the famous case described in The Story of Mel (in Appendix A), interleaving of opcodes on a magnetic drum to minimize fetch delays due to the device's rotational latency). This sort of thing has become less common as the relative costs of programming time and machine resources have changed, but is still found in heavily constrained environments such as industrial embedded systems, and in the code of hackers who just can't let go of that low-level control. See Real Programmer.

In the world of personal computing, bare metal programming (especially in sense 1 but sometimes also in sense 2) is often considered a Good Thing, or at least a necessary evil (because these machines have often been sufficiently slow and poorly designed to make it necessary; see ill-behaved). There, the term usually refers to bypassing the BIOS or OS interface and writing the application to directly access device registers and machine addresses. "To get 19.2 kilobaud on the serial port, you need to get down to the bare metal." People who can do this sort of thing well are held in high regard.

Node:barf, Next:barfmail, Previous:bare metal, Up:= B =

barf /barf/ n.,v.

[common; from mainstream slang meaning `vomit'] 1. interj. Term of disgust. This is the closest hackish equivalent of the Valspeak "gag me with a spoon". (Like, euwww!) See bletch. 2. vi. To say "Barf!" or emit some similar expression of disgust. "I showed him my latest hack and he barfed" means only that he complained about it, not that he literally vomited. 3. vi. To fail to work because of unacceptable input, perhaps with a suitable error message, perhaps not. Examples: "The division operation barfs if you try to divide by 0." (That is, the division operation checks for an attempt to divide by zero, and if one is encountered it causes the operation to fail in some unspecified, but generally obvious, manner.) "The text editor barfs if you try to read in a new file before writing out the old one." See choke, gag. In Commonwealth Hackish, `barf' is generally replaced by `puke' or `vom'. barf is sometimes also used as a metasyntactic variable, like foo or bar.

[uncommon; prob. from the nuclear military] An unexpectedly large quantity of something: a unit of measurement. "Why is /var/adm taking up so much space?" "The logs have grown to several barns." The source of this is clear: when physicists were first studying nuclear interactions, the probability was thought to be proportional to the cross-sectional area of the nucleus (this probability is still called the cross-section). Upon experimenting, they discovered the interactions were far more probable than expected; the nuclei were `as big as a barn'. The units for cross-sections were christened Barns, (10^-24 cm^2) and the book containing cross-sections has a picture of a barn on the cover.

In Commonwealth hackish, `barney' is to fred (sense #1) as bar is to foo. That is, people who commonly use `fred' as their first metasyntactic variable will often use `barney' second. The reference is, of course, to Fred Flintstone and Barney Rubble in the Flintstones cartoons.

baroque adj.

[common] Feature-encrusted; complex; gaudy; verging on excessive. Said of hardware or (esp.) software designs, this has many of the connotations of elephantine or monstrosity but is less extreme and not pejorative in itself. "Metafont even has features to introduce random variations to its letterform output. Now that is baroque!" See also rococo.

Node:BASIC, Next:batbelt, Previous:baroque, Up:= B =

BASIC /bay'-sic/ n.

A programming language, originally designed for Dartmouth's experimental timesharing system in the early 1960s, which for many years was the leading cause of brain damage in proto-hackers. Edsger W. Dijkstra observed in "Selected Writings on Computing: A Personal Perspective" that "It is practically impossible to teach good programming style to students that have had prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration." This is another case (like Pascal) of the cascading lossage that happens when a language deliberately designed as an educational toy gets taken too seriously. A novice can write short BASIC programs (on the order of 10-20 lines) very easily; writing anything longer (a) is very painful, and (b) encourages bad habits that will make it harder to use more powerful languages well. This wouldn't be so bad if historical accidents hadn't made BASIC so common on low-end micros in the 1980s. As it is, it probably ruined tens of thousands of potential wizards.

[1995: Some languages called `BASIC' aren't quite this nasty any more, having acquired Pascal- and C-like procedures and control structures and shed their line numbers. --ESR]

Note: the name is commonly parsed as Beginner's All-purpose Symbolic Instruction Code, but this is a backronym. BASIC was originally named Basic, simply because it was a simple and basic programming language. Because most programming language names were in fact acronyms, BASIC was often capitalized just out of habit or to be silly. No acronym for BASIC originally existed or was intended (as one can verify by reading texts through the early 1970s). Later, around the mid-1970s, people began to make up backronyms for BASIC because they weren't sure. Beginner's All-purpose Symbolic Instruction Code is the one that caught on.

Node:batbelt, Next:batch, Previous:BASIC, Up:= B =

Many hackers routinely hang numerous devices such as pagers, cell-phones, personal organizers, leatherman multitools, pocket knives, flashlights, walkie-talkies, even miniature computers from their belts. When many of these devices are worn at once, the hacker's belt somewhat resembles Batman's utility belt; hence it is referred to as a batbelt.

Node:batch, Next:bathtub curve, Previous:batbelt, Up:= B =

batch adj.

1. Non-interactive. Hackers use this somewhat more loosely than the traditional technical definitions justify; in particular, switches on a normally interactive program that prepare it to receive non-interactive command input are often referred to as `batch mode' switches. A `batch file' is a series of instructions written to be handed to an interactive program running in batch mode. 2. Performance of dreary tasks all at one sitting. "I finally sat down in batch mode and wrote out checks for all those bills; I guess they'll turn the electricity back on next week..." 3. `batching up': Accumulation of a number of small tasks that can be lumped together for greater efficiency. "I'm batching up those letters to send sometime" "I'm batching up bottles to take to the recycling center."

Node:bathtub curve, Next:baud, Previous:batch, Up:= B =

bathtub curve n.

Common term for the curve (resembling an end-to-end section of one of those claw-footed antique bathtubs) that describes the expected failure rate of electronics with time: initially high, dropping to near 0 for most of the system's lifetime, then rising again as it `tires out'. See also burn-in period, infant mortality.

Node:baud, Next:baud barf, Previous:bathtub curve, Up:= B =

baud /bawd/ n.

[simplified from its technical meaning] n. Bits per second. Hence kilobaud or Kbaud, thousands of bits per second. The technical meaning is `level transitions per second'; this coincides with bps only for two-level modulation with no framing or stop bits. Most hackers are aware of these nuances but blithely ignore them.

Historical note: `baud' was originally a unit of telegraph signalling speed, set at one pulse per second. It was proposed at the November, 1926 conference of the Comité Consultatif International Des Communications Télégraphiques as an improvement on the then standard practice of referring to line speeds in terms of words per minute, and named for Jean Maurice Emile Baudot (1845-1903), a French engineer who did a lot of pioneering work in early teleprinters.

Node:baud barf, Next:baz, Previous:baud, Up:= B =

baud barf /bawd barf/ n.

The garbage one gets a terminal (or terminal emulator) when using a modem connection with some protocol setting (esp. line speed) incorrect, or when someone picks up a voice extension on the same line, or when really bad line noise disrupts the connection. Baud barf is not completely random, by the way; hackers with a lot of serial-line experience can usually tell whether the device at the other end is expecting a higher or lower speed than the terminal is set to. Really experienced ones can identify particular speeds.

Node:baz, Next:bazaar, Previous:baud barf, Up:= B =

baz /baz/ n.

1. [common] The third metasyntactic variable "Suppose we have three functions: FOO, BAR, and BAZ. FOO calls BAR, which calls BAZ...." (See also fum) 2. interj. A term of mild annoyance. In this usage the term is often drawn out for 2 or 3 seconds, producing an effect not unlike the bleating of a sheep; /baaaaaaz/. 3. Occasionally appended to foo to produce `foobaz'.

Earlier versions of this lexicon derived `baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout `Bazz Fazz!' or `Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

bazaar n.,adj.

In 1997, after meditatating on the success of Linux for three years, the Jargon File's own editor ESR wrote an analytical paper on hacker culture and development models titled The Cathedral and the Bazaar. The main argument of the paper was that Brooks's Law is not the whole story; given the right social machinery, debugging can be efficiently parallelized across large numbers of programmers. The title metaphor caught on (see also cathedral), and the style of development typical in the Linux community is now often referred to as the bazaar mode. Its characteristics include releasing code early and often, and actively seeking the largest possible pool of peer reviewers.

Node:bboard, Next:BBS, Previous:bazaar, Up:= B =

bboard /bee'bord/ n.

[contraction of `bulletin board'] 1. Any electronic bulletin board; esp. used of BBS systems running on personal micros, less frequently of a Usenet newsgroup (in fact, use of this term for a newsgroup generally marks one either as a newbie fresh in from the BBS world or as a real old-timer predating Usenet). 2. At CMU and other colleges with similar facilities, refers to campus-wide electronic bulletin boards. 3. The term `physical bboard' is sometimes used to refer to an old-fashioned, non-electronic cork-and-thumbtack memo board. At CMU, it refers to a particular one outside the CS Lounge.

In either of senses 1 or 2, the term is usually prefixed by the name of the intended board (`the Moonlight Casino bboard' or `market bboard'); however, if the context is clear, the better-read bboards may be referred to by name alone, as in (at CMU) "Don't post for-sale ads on general".

BBS /B-B-S/ n.

[common; abbreviation, `Bulletin Board System'] An electronic bulletin board system; that is, a message database where people can log in and leave broadcast messages for others grouped (typically) into topic groups. The term was especially applied to the thousands of local BBS systems that operated during the pre-Internet microcomputer era of roughly 1980 to 1995, typically run by amateurs for fun out of their homes on MS-DOS boxes with a single modem line each. Fans of Usenet and Internet or the big commercial timesharing bboards such as CompuServe and GEnie tended to consider local BBSes the low-rent district of the hacker culture, but they served a valuable function by knitting together lots of hackers and users in the personal-micro world who would otherwise have been unable to exchange code at all. Post-Internet, BBSs are likely to be local newsgroups on an ISP; efficiency has increased but a certain flavor has been lost. See also bboard.

BCPL // n.

[abbreviation, `Basic Combined Programming Language') A programming language developed by Martin Richards in Cambridge in 1967. It is remarkable for its rich syntax, small size of compiler (it can be run in 16k) and extreme portability. It reached break-even point at a very early stage, and was the language in which the original hello world program was written. It has been ported to so many different systems that its creator confesses to having lost count. It has only one data type (a machine word) which can be used as an integer, a character, a floating point number, a pointer, or almost anything else, depending on context. BCPL was a precursor of C, which inherited some of its features.
