1. [ITS] A derogatory term for Unix, derived
from Unix weenie. According to one noted ex-ITSer,
it is the operating system preferred by Unix Weenies: typified by
poor modularity, poor reliability, hard file deletion, no file version
numbers, case sensitivity everywhere, and users who believe that these are
all advantages
. (Some ITS fans behave as though they believe Unix
stole a future that rightfully belonged to them. See
ITS, sense 2.)
2. [Brown University] A Unix-like OS developed for tutorial purposes at Brown University. See http://www.cs.brown.edu/courses/cs167/weenix.html. Named independently of the ITS usage.
