:braino: /bray'no/ /n./ Syn. for {thinko}. See also
{brain fart}.

:branch to Fishkill: /n./ [IBM: from the location of one of the
corporation's facilities] Any unexpected jump in a program that
produces catastrophic or just plain weird results. See {jump
off into never-never land}, {hyperspace}.

:bread crumbs: /n./ Debugging statements inserted into a
program that emit output or log indicators of the program's
{state} to a file so you can see where it dies or pin down the
cause of surprising behavior. The term is probably a reference to
the Hansel and Gretel story from the Brothers Grimm; in several
variants, a character leaves a trail of bread crumbs so as not to
get lost in the woods.

:break: 1. /vt./ To cause to be {broken} (in any sense).
"Your latest patch to the editor broke the paragraph commands."
2. /v./ (of a program) To stop temporarily, so that it may
debugged.
The place where it stops is a `breakpoint'. 3. [techspeak]
/vi./ To send an RS-232 break (two character widths of line high)
over a serial comm line. 4. [Unix] /vi./ To strike whatever key
currently causes the tty driver to send SIGINT to the current
process. Normally, break (sense 3), delete or {control-C} does
this. 5. `break break' may be said to interrupt a conversation
(this is an example of verb doubling). This usage comes from radio
communications, which in turn probably came from landline
telegraph/teleprinter usage, as badly abused in the Citizen's Band
craze a few years ago.
