Plan 9 n. In the late 1980s, researchers at Bell Labs (especially Rob Pike of Kernighan & Pike fame) got bored with the limitations of UNIX and decided to reimplement the entire system. The result was called Plan 9 in ?the Bell Labs tradition of selecting names that make marketeers wince.? The developers also wished to pay homage to the famous film, ?Plan 9 From Outer Space?, considered by some to be the worst movie ever made. The source is available for download under open-source terms. The developers and a small fan base hang out at comp.os.plan9, where one can occasionally hear ?If you want UNIX, you know where to find it?

Plan 9 (Named after the classically bad, exceptionally low-budget SF film "Plan 9 from Outer Space") An operating system developed at Bell Labs by many researchers previously intimately involved with Unix. Plan 9 is superficially Unix-like but features far finer control over the name-space (on a per-process basis) and is inherently distributed and scalable. Plan 9 is divided according to service functions. CPU servers concentrate computing power into large multiprocessors; file servers provide repositories for storage and terminals give each user of the system a dedicated computer with bitmap screen and mouse on which to run a window system. The sharing of computing and file storage services provides a sense of community for a group of programmers, amortises costs and centralises and hence simplifies management and administration. The pieces communicate by a single protocol, built above a reliable data transport layer offered by an appropriate network, that defines each service as a rooted tree of files. Even for services not usually considered as files, the unified design permits some simplification. Each process has a local file name space that contains attachments to all services the process is using and thereby to the files in those services. One of the most important jobs of a terminal is to support its user's customised view of the entire system as represented by the services visible in the name space. ( (2005-02-15)
