Halloween Documents: n. A pair of Microsoft internal strategy
memoranda leaked to ESR in late 1998 that confirmed everybody's
paranoia about the current Evil Empire. These documents
(http://www.opensource.org/halloween/) praised the technical
excellence of Linux and outlined a counterstrategy of attempting
to lock in customers by "de-commoditizing" Internet protocols and
services. They were extensively cited on the Internet and in the
press and proved so embarrassing that Microsoft PR barely said a
word in public for six months afterwards.
