If you want the Gory Details, see my /CurriculumVitae.
In brief: I've been working with Unix since 1979, hacking Unix kernels since 1982, and started using Linux with the Manchester Computer Centre distribution in 1989. At that time there were legal reasons not to contribute --- I was, or could be said to be, `mentally contaminated' by seeing AT&T's source code. Fortunately that's no longer an issue, as I now hack Linux kernels part-time for a living with the SSRG group.
Old work is described in /OldWork. Current work is not public.
My publications are on my SSRG home page.

I'm now full time with NICTA in the Software Systems Research Group (SSRG) --- see http://www.nicta.com.au/articulate/ for one cool thing I worked on a couple of years ago.
Just for fun I've been attempting to modify the firmware of an WNDR3700 wireless router.
