ITS
/I.T.S/, n.
1. Incompatible Time-sharing System, an influential though highly
idiosyncratic operating system written for PDP-6s and PDP-10s at MIT
and long used at the MIT AI Lab. Much AI-hacker jargon derives from
ITS folklore, and to have been `an ITS hacker' qualifies one
instantly
as an old-timer of the most venerable sort. ITS pioneered many
important innovations, including transparent file sharing between
machines and terminal-independent I/O. After about 1982, most actual
work was shifted to newer machines, with the remaining ITS boxes run
essentially as a hobby and service to the hacker community. The
shutdown of the lab's last ITS machine in May 1990 marked the end of
an era and sent old-time hackers into mourning nationwide (see high
moby). There is an ITS home page.
2. A mythical image of operating-system perfection worshiped by a
bizarre, fervent retro-cult of old-time hackers and ex-users (see
troglodyte, sense 2). ITS worshipers manage somehow to continue
believing that an OS maintained by assembly-language hand-hacking
that
supported only monocase 6-character filenames in one directory per
account remains superior to today's state of commercial art (their
venom against Unix is particularly intense). See also holy wars,
Weenix.
