Van Jacobson rocks - 15:13
The next two talks I saw today were David Gibson talking about the new device trees and device tree compiler they are using for all powerpc archs (and could in theory be used for unrelated archs such as arm or x86 variants). Device Trees for embedded systems (lca link)

However the standout talk of the entire conference was probably the next one I saw. Van Jacobson, you know one of the guys that was involved with creating the Internet, and designed protocols in such a way that they do not suck and thus the Internet does not fall over. Anyway he presented a seminar with suggestions for speeding up the Linux tcp stack (lca link).

Van Jacobson had done the code, the tests and the work had really obvious merit for the conclusions, he presented to the likes of Dave M, Linus and Rusty, everyone else liked the talk too.

More trench notes. - 11:12
Last night we had a rather cool Professional Delegates Networking Session, with thanks to IBM and HP for the beers and food, at the Larnarch Castle in Dunedin, neat location. This morning the keynote was from Damian Conway talking about lessons learnt (technical and social) from the perl 6 development process. Next I went to Chris Yeoh's talk about Managing Memory in variable sized chunks. Then I got to see the cool new stuff Wayne Piekarski has done in the augmented reality gear and software he has been presenting about since lca began in 1999.

I have uploaded some notes, not much from Chris' talk but a but from the rest.

Wayne has managed to make the tinmith system a lot smaller now, to the extent the entire system fits in a bum bag sized case with some batteries mounted on the hips (2 8 Amp Hour batteries, I suspect if he used NiMH 4.4 Amp Hour cells he could get the battery packs even smaller and lighter too).

Damian Conway rocked seriously, a great speaker and I am a perl fan so it was fun to see.
