primary task was.

:demon dialer: /n./ A program which repeatedly calls the same
telephone number. Demon dialing may be benign (as when a number of
communications programs contend for legitimate access to a {BBS}
line) or malign (that is, used as a prank or denial-of-service
attack). This term dates from the {blue box} days of the 1970s
and early 1980s and is now semi-obsolescent among {phreaker}s;
see {war dialer} for its contemporary progeny.

:depeditate: /dee-ped'*-tayt/ /n./ [by (faulty) analogy with
`decapitate'] Humorously, to cut off the feet of. When one is
using some computer-aided typesetting tools, careless placement of
text blocks within a page or above a rule can result in chopped-off
letter descenders. Such letters are said to have been depeditated.

:deprecated: /adj./ Said of a program or feature that is
considered obsolescent and in the process of being phased out,
usually in favor of a specified replacement. Deprecated features
can, unfortunately, linger on for many years. This term appears
with distressing frequency in standards documents when the
committees writing the documents realize that large amounts of
extant (and presumably happily working) code depend on the
feature(s) that have passed out of favor. See also {dusty
deck}.

:derf: /derf/ /v.,n./ [PLATO] The act of exploiting a
terminal which someone else has absentmindedly left logged on, to
use that person's account, especially to post articles intended to
make an ass of the victim you're impersonating.
