= D =
dusty deck n.
Old software (especially applications) which
one is obliged to remain compatible with, or to maintain (DP
types call this `legacy code', a term hackers consider smarmy and
excessively reverent). The term implies that the software in
question is a holdover from card-punch days. Used esp. when
referring to old scientific and number-crunching software,
much of which was written in FORTRAN and very poorly documented but
is believed to be too expensive to replace. See fossil;
compare crawling horror.
