rain dance n.
1. Any ceremonial action taken to correct a hardware problem,
with the expectation that nothing will be accomplished. This
especially applies to reseating printed circuit boards,
reconnecting cables, etc. "I can't boot up the machine. We'll
have to wait for Greg to do his rain dance." 2. Any arcane
sequence of actions performed with computers or software in order
to achieve some goal; the term is usually restricted to rituals
that include both an incantation or two and physical activity
or motion. Compare magic, voodoo programming, black art, cargo cult programming,
wave a dead
chicken; see also casting the runes.
