CALU photos, day 2

Day 2 started (late) with the keynote speech and then the first threesessions of short talks/papers. We ordered 120 pizzas for dinner andafterwards went off for the BOF sessions.

Saturday was sponsored by TPC, the local distributors of Cyclades products.
Conference organisers Rusty (left) and Nathan prove conclusively that even a late morning (10:30) doesn't mean you'll have everything ready.
Meanwhile staring down at them is this fairly congenial mob who were waiting for the Keynote speech by John "maddog" Hall.
John claims that "Venimus, Vidimus, Dolavimus" translates to "I came, I saw, I hacked", but since my latin is non-existent I'll have to take his word for it.
"Take No Prisoners" was one of the most inspiring things I've ever heard. I'm sure I saw a tear in the eye of many an attendee at a couple of stages.
Favorite "Take No Prisoners" quote: There are 5.6 billion people in the world, and approximately 400 million installed operating systems. That means that 5.2 billion people have yet to choose their operating system, and we have to get to them before Bill does.
Another cool quote: The next Albert Einstein of computer science is out there somewhere, and getting Linux to as many people in as many countries as possible is our best chance of finding them.
How can you call a Taiwanese man an evil pirate when he is feeding and clothing his family on $1 per day and is then told he'll have to pay $600 for Microsoft Office?
Ken McDonell from SGI gave a fascinating talk on "System Level Performance Management". They have developed some great monitoring and system performance visualisation software, but it's SGI internal use only at the moment. They are still looking at the possibilities for open sourcing it.
Running Linux on the L4 microkernel, presented by Andrew O'Brien.
Graeme Cross took time out from his busy schedule presenting "Scientific Linux" to pose for the camera. I've heard bits of this talk before, it's good stuff.
Paul Mackerras did a great fill-in job presenting "PowerPC Linux" after Cort Dougan (who was originally scheduled to present "Linux/PPC Goes 64-Bit") got lost in transit somewhere between Alberquerque and Denver (I kid you not!) and never made it to the conference.
Duncan Grove told a cluster of soon-to-be number crunching listeners how to build a Beowulf system.
Tridge was back for round two, this time giving everone a complete run down of rsync and his plans to get it into the http protocol. Tridge is getting a factor of 5 speed-up using rsync - this is really exciting!
Kernel hacker extrordinaire and Red Hat employee David Miller gave an energetic presentation on the scalability of the Linux networking stack and what they're doing to improve it in 2.3.
I doubt there would have been more than half a dozen people who understood everything David said (and those people were probably the other kernel hackers in the audience), but it was fascinating nonetheless. Linux is apparently moving towards an implementation where tcp is done in a user space context, an idea which came originally from the great Van Jacobson.
The clever thing about user space TCP is that if your performance drops and you're having trouble processing packets then it looks to the other end exactly like network latency or bandwidth problems, and they will back off appropriately. How cool is that?
