UNIX
/yoo'niks/ [In the authors' words, "A weak pun on
Multics"] n. (also `Unix') An interactive time-sharing system
originally invented in 1969 by Ken Thompson after Bell Labs left
the Multics project, originally so he could play games on his
scavenged PDP-7. Dennis Ritchie, the inventor of C, is considered
a co-author of the system. The turning point in UNIX's history
came when it was reimplemented almost entirely in C during
1972--1974, making it the first source-portable OS. UNIX
subsequently underwent mutations and expansions at the hands of
many different people, resulting in a uniquely flexible and
developer-friendly environment. In 1991, UNIX is the most widely
used multiuser general-purpose operating system in the world. Many
people consider this the most important victory yet of hackerdom
over industry opposition (but see
UNIX weenie and {UNIX
conspiracy} for an opposing point of view). See
