Plan 9

Bell Labs look like they’ve just opened up a little more of their source-code in the shape of some system commands.

• http://plan9.bell-labs.com/sources/plan9/sys/src/
• http://plan9.bell-labs.com/sources/plan9/sys/src/cmd/

It’s worth a browse just to have a look at how some of these things were implemented.

A quick update, seems that someone has Plan9 running on a raspberry PI.
