It is my pleasure to announce that kernelthread.com now has experimental Forums, with the theoretically unapproachable goal of fostering "zero-zealotry, high SNR" discussions on technical and strategic topics in operating systems and related areas. Current forums include Mac OS X, Unix, and Virtualization.
Here is a link to the Mission Statement.
gbaunix is a rather contrived experiment in which we run an ancient version of the UNIX operating system on a popular hand-held game system using a simulator. Specifically, it is 5th edition UNIX (1974) running on Nintendo's Game Boy Advance, with SIMH as the core simulator.
