BWQ /B-W-Q/ n.

[IBM: abbreviation, `Buzz Word Quotient'] The percentage of

buzzwords in a speech or documents. Usually roughly proportional

to bogosity. See TLA.

[common] 1. Said of an operation (especially a repetitive,

trivial, and/or tedious one) that ought to be performed

automatically by the computer, but which a hacker instead has to

step tediously through. "My mailer doesn't have a command to

include the text of the message I'm replying to, so I have to do

it by hand." This does not necessarily mean the speaker has to

retype a copy of the message; it might refer to, say, dropping

into a subshell from the mailer, making a copy of one's mailbox

file, reading that into an editor, locating the top and bottom of

the message in question, deleting the rest of the file, inserting

`>' characters on each line, writing the file, leaving the

editor, returning to the mailer, reading the file in, and later

remembering to delete the file. Compare eyeball search. 2. By extension,

writing code which does something in an explicit or low-level way

for which a presupplied library routine ought to have been

available. "This cretinous B-tree library doesn't supply a decent

iterator, so I'm having to walk the trees by hand."

B =

byte /bi:t/ n.

[techspeak] A unit of memory or data equal to the amount used

to represent one character; on modern architectures this is

usually 8 bits, but may be 9 on 36-bit machines. Some older

architectures used `byte' for quantities of 6 or 7 bits, and the

PDP-10 supported `bytes' that were actually bitfields of 1 to 36

bits! These usages are now obsolete, and even 9-bit bytes have

become rare in the general trend toward power-of-2 word

sizes.

Historical note: The term was coined by Werner Buchholz in

1956 during the early design phase for the IBM Stretch computer;

originally it was described as 1 to 6 bits (typical I/O equipment

of the period used 6-bit chunks of information). The move to an

8-bit byte happened in late 1956, and this size was later adopted

and promulgated as a standard by the System/360. The word was

coined by mutating the word `bite' so it would not be

accidentally misspelled as bit. See

also nybble.
