We have three keynotes this year: Wednesday morning, Thursday morning, and the closing keynote Friday afternoon.
We invited Andy because he deals with peta-scale data warehousing, big databases and all that fun stuff. I love hearing talks about big big big data. There are always plenty of surprises when things get that big. As conference co-chair, I can't wait to meet him in person!
Usenix LISA 2011 is Dec 4-9 in Boston. You can register any time, but you get a discount if you register by Nov 14. I look forward to seeing you there!
