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

The most famous [1284]pseudo, and the prototypical [1285]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 [1286]talk mode

abbreviations, a long [1287]sig block (sometimes even a [1288]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, [1289]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:

[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 [1290]Jeff K. --ESR]

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,

What faces a [1302]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 [1303]VMS. Often contracted to `Gray

[IBM] The power switch on a computer, esp. the `Emergency Pull' switch

on an IBM [1313]mainframe or the power switch on an IBM PC where it

really is large and red. "This !@%$% [1314]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 [1315]TLAs, this is often abbreviated

as `BRS' (this has also become established on FidoNet and in the PC

[1316]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 [1317]molly-guard).

[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 [1332]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 [1333]little-endian, [1334]middle-endian,

[1335]NUXI problem, [1336]swab. 2. An [1337]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 [1338]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 [1342]moby, sense 4). See also [1343]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 [1344]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:

computer, language, operating system, editor, or other tool (see

[1348]religious issues). 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. It is

truly said "You can tell a bigot, but you can't tell him much."

[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.

A bit is said to be set' if its value is true or 1, andreset' or

`clear' if its value is false or 0. One speaks of setting and clearing

bits. To [1354]toggle or `invert' a bit is to change it, either from 0

to 1 or from 1 to 0. See also [1355]flag, [1356]trit, [1357]mode bit.

The term `bit' first appeared in print in the computer-science sense

in a 1948 paper by information theorist Claude Shannon, and was there

credited to the early computer scientist John Tukey (who also seems to

have coined the term software'). Tukey records thatbit' evolved

over a lunch table as a handier alternative to bigit' orbinit', at

a conference in the winter of 1943-44.

B =

bit bang n.

Transmission of data on a serial line, when accomplished by rapidly

tweaking a single output bit, in software, at the appropriate times.

The technique is a simple loop with eight OUT and SHIFT instruction

pairs for each byte. Input is more interesting. And full duplex (doing

input and output at the same time) is one way to separate the real

hackers from the [1361]wannabees.

Bit bang was used on certain early models of Prime computers,

presumably when UARTs were too expensive, and on archaic Z80 micros

with a Zilog PIO but no SIO. In an interesting instance of the

[1362]cycle of reincarnation, this technique returned to use in the

early 1990s on some RISC architectures because it consumes such an

infinitesimal part of the processor that it actually makes sense not

to have a UART. Compare [1363]cycle of reincarnation.

(alt. `bit diddling' or [1367]bit twiddling) Term used to describe any

of several kinds of low-level programming characterized by

manipulation of [1368]bit, [1369]flag, [1370]nybble, and other

smaller-than-character-sized pieces of data; these include low-level

device control, encryption algorithms, checksum and error-correcting

codes, hash functions, some flavors of graphics programming (see

[1371]bitblt), and assembler/compiler code generation. May connote

either tedium or a real technical challenge (more usually the former).

"The command decoding for the new tape driver looks pretty solid but

the bit-bashing for the control registers still has bugs." See also

[very common] 1. The universal data sink (originally, the mythical

receptacle used to catch bits when they fall off the end of a register

during a shift instruction). Discarded, lost, or destroyed data is

said to have `gone to the bit bucket'. On [1377]Unix, often used for

[1378]/dev/null. Sometimes amplified as `the Great Bit Bucket in the

Sky'. 2. The place where all lost mail and news messages eventually

go. The selection is performed according to [1379]Finagle's Law;

important mail is much more likely to end up in the bit bucket than

junk mail, which has an almost 100% probability of getting delivered.

Routing to the bit bucket is automatically performed by mail-transfer

agents, news systems, and the lower layers of the network. 3. The

ideal location for all
