I got 'persuaded' to record a couple of talks on video recently. They
cover the same kind of stuff as I did at techadventure - performance
and availability - but in a rather more formal setting.
If you're interested, they're here:
http://xdelta.blip.tv/file/2247136/ - system performance
characteristics
http://xdelta.blip.tv/file/2233391/ - design of high-availability
systems
I think I much preferred the informality and interaction we had at
techadventure! It was good fun.
Cheers, Colin.
