[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.

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.

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".

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

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.

beam vt.

[from Star Trek Classic's "Beam me up, Scotty!"] 1. To transfer softcopy of a file electronically; most often in combining forms such as `beam me a copy' or `beam that over to his site'. 2. Palm Pilot users very commonly use this term for the act of exchanging bits via the infrared links on their machines (this term seems to have originated with the ill-fated Newton Message Pad). Compare blast, snarf, BLT.

bells and whistles n.

[common] Features added to a program or system to make it more flavorful from a hacker's point of view, without necessarily adding to its utility for its primary function. Distinguished from chrome, which is intended to attract users. "Now that we've got the basic program working, let's go back and add some bells and whistles." No one seems to know what distinguishes a bell from a whistle. The recognized emphatic form is "bells, whistles, and gongs".

It used to be thought that this term derived from the toyboxes on theater organs. However, the "and gongs" strongly suggests a different origin, at sea. Before powered horns, ships routinely used bells, whistles, and gongs to signal each other over longer distances than voice can carry.

Node:bells whistles and gongs, Next:benchmark, Previous:bells and whistles, Up:= B =

[techspeak] An inaccurate measure of computer performance. "In the computer industry, there are three kinds of lies: lies, damn lies, and benchmarks." Well-known ones include Whetstone, Dhrystone, Rhealstone (see h), the Gabriel LISP benchmarks (see gabriel), the SPECmark suite, and LINPACK. See also machoflops, MIPS, smoke and mirrors.

Berkeley Quality Software adj.

(often abbreviated `BQS') Term used in a pejorative sense to refer to software that was apparently created by rather spaced-out hackers late at night to solve some unique problem. It usually has nonexistent, incomplete, or incorrect documentation, has been tested on at least two examples, and core dumps when anyone else attempts to use it. This term was frequently applied to early versions of the dbx(1) debugger. See also Berzerkeley.

Note to British and Commonwealth readers: that's /berk'lee/, not /bark'lee/ as in British Received Pronunciation.

berklix /berk'liks/ n.,adj.

[contraction of `Berkeley Unix'] See BSD. Not used at Berkeley itself. May be more common among suits attempting to sound like cognoscenti than among hackers, who usually just say `BSD'.

Berzerkeley /b*r-zer'klee/ n.

[from `berserk', via the name of a now-deceased record label; poss. originated by famed columnist Herb Caen] Humorous distortion of `Berkeley' used esp. to refer to the practices or products of the BSD Unix hackers. See software bloat, Missed'em-five, Berkeley Quality Software.

Mainstream use of this term in reference to the cultural and political peculiarities of UC Berkeley as a whole has been reported from as far back as the 1960s.

Node:beta, Next:BFI, Previous:Berzerkeley, Up:= B =

beta /bay't*/, /be't*/ or (Commonwealth) /bee't*/ n.

1. Mostly working, but still under test; usu. used with `in': `in beta'. In the Real World, systems (hardware or software) software often go through two stages of release testing: Alpha (in-house) and Beta (out-house?). Beta releases are generally made to a group of lucky (or unlucky) trusted customers. 2. Anything that is new and experimental. "His girlfriend is in beta" means that he is still testing for compatibility and reserving judgment. 3. Flaky; dubious; suspect (since beta software is notoriously buggy).

Historical note: More formally, to beta-test is to test a pre-release (potentially unreliable) version of a piece of software by making it available to selected (or self-selected) customers and users. This term derives from early 1960s terminology for product cycle checkpoints, first used at IBM but later standard throughout the industry. `Alpha Test' was the unit, module, or component test phase; `Beta Test' was initial system test. These themselves came from earlier A- and B-tests for hardware. The A-test was a feasibility and manufacturability evaluation done before any commitment to design and development. The B-test was a demonstration that the engineering model functioned as specified. The C-test (corresponding to today's beta) was the B-test performed on early samples of the production design, and the D test was the C test repeated after the model had been in production a while.

See brute force and ignorance. Also encountered in the variants `BFMI', `brute force and massive ignorance' and `BFBI' `brute force and bloody ignorance'. In dome parts of the U.S. this abbreviation was probably reinforced by a company called Browning-Ferris Industries who used to be in the waste-management business; a large BFI logo in white-on-blue could be seen on the sides of garbage trucks.

The act said to have been performed on trademarks (such as PostScript, NeXT, NeWS, VisiCalc, FrameMaker, TK!solver, EasyWriter) that have been raised above the ruck of common coinage by nonstandard capitalization. Too many marketroid types think this sort of thing is really cute, even the 2,317th time they do it. Compare studlycaps.

Node:B1FF, Next:BI, Previous:BiCapitalization, Up:= B =

B1FF /bif/ [Usenet] (alt. `BIFF') n.

The most famous pseudo, and the prototypical newbie. Articles from B1FF feature all uppercase letters sprinkled liberally with bangs, typos, `cute' misspellings (EVRY BUDY LUVS GOOD OLD BIFF CUZ HE"S A K00L DOOD AN HE RITES REEL AWESUM THINGZ IN CAPITULL LETTRS LIKE THIS!!!), use (and often misuse) of fragments of talk mode abbreviations, a long sig block (sometimes even a doubled sig), and unbounded naivete. B1FF posts articles using his elder brother's VIC-20. B1FF's location is a mystery, as his articles appear to come from a variety of sites. However, BITNET seems to be the most frequent origin. The theory that B1FF is a denizen of BITNET is supported by B1FF's (unfortunately invalid) electronic mail address: [email protected].

[1993: Now It Can Be Told! My spies inform me that B1FF was originally created by Joe Talmadge <[email protected]>, also the author of the infamous and much-plagiarized "Flamer's Bible". The BIFF filter he wrote was later passed to Richard Sexton, who posted BIFFisms much more widely. Versions have since been posted for the amusement of the net at large. See also Jeff K. --ESR]

To notify someone of incoming mail. From the BSD utility biff(1), which was in turn named after a friendly dog who used to chase frisbees in the halls at UCB while 4.2BSD was in development. There was a legend that it had a habit of barking whenever the mailman came, but the author of biff says this is not true. No relation to B1FF.

What faces a VMS user searching for documentation. A full VMS kit comes on a pallet, the documentation taking up around 15 feet of shelf space before the addition of layered products such as compilers, databases, multivendor networking, and programming tools. Recent (since VMS version 5) documentation comes with gray binders; under VMS version 4 the binders were orange (`big orange wall'), and under version 3 they were blue. See VMS. Often contracted to `Gray Wall'.

[common] Large, expensive, ultra-fast computers. Used generally of number-crunching supercomputers such as Crays, but can include more conventional big commercial IBMish mainframes. Term of approval; compare heavy metal, oppose dinosaur.

Node:Big Red Switch, Next:Big Room, Previous:big iron, Up:= B =

Big Red Switch n.

[IBM] The power switch on a computer, esp. the `Emergency Pull' switch on an IBM mainframe or the power switch on an IBM PC where it really is large and red. "This !@%$% bitty box is hung again; time to hit the Big Red Switch." Sources at IBM report that, in tune with the company's passion for TLAs, this is often abbreviated as `BRS' (this has also become established on FidoNet and in the PC clone world). It is alleged that the emergency pull switch on an IBM 360/91 actually fired a non-conducting bolt into the main power feed; the BRSes on more recent mainframes physically drop a block into place so that they can't be pushed back in. People get fired for pulling them, especially inappropriately (see also molly-guard). Compare power cycle, three-finger salute, 120 reset; see also scram switch.

big-endian adj.

[common; From Swift's "Gulliver's Travels" via the famous paper "On Holy Wars and a Plea for Peace" by Danny Cohen, USC/ISI IEN 137, dated April 1, 1980] 1. Describes a computer architecture in which, within a given multi-byte numeric representation, the most significant byte has the lowest address (the word is stored `big-end-first'). Most processors, including the IBM 370 family, the PDP-10, the Motorola microprocessor families, and most of the various RISC designs are big-endian. Big-endian byte order is also sometimes called `network order'. See little-endian, middle-endian, NUXI problem, swab. 2. An Internet address the wrong way round. Most of the world follows the Internet standard and writes email addresses starting with the name of the computer and ending up with the name of the country. In the U.K. the Joint Networking Team had decided to do it the other way round before the Internet domain standard was established. Most gateway sites have ad-hockery in their mailers to handle this, but can still be confused. In particular, the address [email protected]_ could be interpreted in JANET's big-endian way as one in the U.K. (domain _uk_) or in the standard little-endian way as one in the domain _as_ (American Samoa) on the opposite side of the world.

bignum /big'nuhm/ n.

[common; orig. from MIT MacLISP] 1. [techspeak] A multiple-precision computer representation for very large integers. 2. More generally, any very large number. "Have you ever looked at the United States Budget? There's bignums for you!" 3. [Stanford] In backgammon, large numbers on the dice especially a roll of double fives or double sixes (compare moby, sense 4). See also El Camino Bignum.

Sense 1 may require some explanation. Most computer languages provide a kind of data called `integer', but such computer integers are usually very limited in size; usually they must be smaller than 2^(31) (2,147,483,648) or (on a bitty box) 2^(15) (32,768). If you want to work with numbers larger than that, you have to use floating-point numbers, which are usually accurate to only six or seven decimal places. Computer languages that provide bignums can perform exact calculations on very large numbers, such as 1000! (the factorial of 1000, which is 1000 times 999 times 998 times ... times 2 times 1). For example, this value for 1000! was computed by the MacLISP system using bignums:

Usually found with a specifier; thus, `cray bigot', `ITS bigot', `APL bigot', `VMS bigot', `Berkeley bigot'. Real bigots can be distinguished from mere partisans or zealots by the fact that they refuse to learn alternatives even when the march of time and/or technology is threatening to obsolete the favored tool.

bit n.

[from the mainstream meaning and `Binary digIT'] 1. [techspeak] The unit of information; the amount of information obtained by asking a yes-or-no question for which the two outcomes are equally probable. 2. [techspeak] A computational quantity that can take on one of two values, such as true and false or 0 and 1. 3. A mental flag: a reminder that something should be done eventually. "I have a bit set for you." (I haven't seen you for a while, and I'm supposed to tell or ask you something.) 4. More generally, a (possibly incorrect) mental state of belief. "I have a bit set that says that you were the last guy to hack on EMACS." (Meaning "I think you were the last guy to hack on EMACS, and what I am about to say is predicated on this, so please stop me if this isn't true.")

"I just need one bit from you" is a polite way of indicating that you intend only a short interruption for a question that can presumably be answered yes or no.
