Line 2: ==Programming== The kernel is written primarily in [[C]], with a minimum of assembly for greater portability. The user-level applications are mostly in [[C]] or the [[rc]] shell. Plan 9 is designed in such a way that the "everything is a file" metaphor extends very well. Network connections can be accessed through /net/tcp, for example, and mouse events are written in plain text to /dev/mouse. Every [[process]] has a separate namespace. Available languages include: C (Plan 9 dialect) rc [[sh]] ([[POSIX]] emulation) [[Perl]] [[Python]] [[Haskell]] [[Assembly]] (all platforms share the same syntax; less machine-specific) ==GUI== The creators of Plan 9 took the opportunity to build graphics capabilities into the system from the ground up, unlike UNIX. The most frequently-used "window manager" for Plan 9 is called rio, as seen in [http://csplan9.rit.edu/users/john/rosettacode.png this image]. ==Compatibility== Plan 9 is not [[POSIX]]-compliant, although it shares similarities with POSIX systems. The architects decided to create a new operating system without backwards-compatibility baggage, which allowed them greater freedom in implementing whatever they thought was important. There is, however, a POSIX emulation layer which allows compilation of some POSIX programs. ==External Links== [http://en.wikipedia.org/wiki/Plan_9_from_Bell_Labs Wikipedia: Plan 9 from Bell Labs] * [http://plan9.bell-labs.com/plan9/ Plan 9 homepage]
