:blow an EPROM: /bloh *n ee'prom/ /v./ (alt. `blast an
EPROM', `burn an EPROM') To program a read-only memory, e.g.
for use with an embedded system. This term arose because the
programming process for the Programmable Read-Only Memories (PROMs)
that preceded present-day Erasable Programmable Read-Only Memories
(EPROMs) involved intentionally blowing tiny electrical fuses on
the chip. The usage lives on (it's too vivid and expressive to
discard) even though the write process on EPROMs is nondestructive.

:blow away: /vt./ To remove (files and directories) from
permanent storage, generally by accident. "He reformatted the
wrong partition and blew away last night's netnews." Oppose
{nuke}.

:blow out: /vi./ [prob. from mining and tunneling jargon] Of
software, to fail spectacularly; almost as serious as {crash and
burn}. See {blow past}, {blow up}, {die horribly}.

:blow past: /vt./ To {blow out} despite a safeguard. "The
server blew past the 5K reserve buffer."

:blow up: /vi./ 1. [scientific computation] To become unstable.
Suggests that the computation is diverging so rapidly that it will
soon overflow or at least go {nonlinear}. 2. Syn. {blow
out}.

:BLT: /B-L-T/, /bl*t/ or (rarely) /belt/ /n.,vt./ Synonym
for {blit}. This is the original form of {blit} and the
ancestor of {bitblt}. It referred to any large bit-field copy
or move operation (one resource-intensive memory-shuffling
