Google Indexing gets high on Caffeine

Last August, I wrote about Google testing the new Caffeine infrastructure. Today, Carrie Grimes announced on their blog that the new indexing system is complete.
Caffeine provides 50 percent fresher results for web searches than our last index... Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally...
My congratulations to the search infrastructure team. It sounds like a significant milestone!

SIGMOD 2010 live stream

Just a quick note to say that I'm back from holiday. I'm settled in Barcelona for the summer, so the posting time schedule may be slightly shifted.

The SIGMOD 2010 conference is underway this week. The papers are online at the ACM DL, SIGMOD page. The keynote talks are being streamed live. Today is a keynote talk by Jon Kleinberg at 8:30am EDT.

Also, in case you've been living under a rock (like me), you can catch up on the WSDM 2010 videos that have been online for awhile.
