Google Talk at UPenn, 3 PM Tuesday

I mentioned this at dinner tonight, and thought I might as well post
it to the list on the off chance anyone can make it tomorrow.

There's no need to register or sign in for this talk; just show up.
Also, while I can't guarantee anything, these afternoon talks often

Levine Hall, by the way, is Penn's shiny new Computer Science
building.  It's somewhat hidden between 33rd St., 34th St., Walnut
St., and Locust Walk.  The building on the SE corner of 34th and

Google faces two large technical challenges: ensuring that our search
results are as relevant as possible, and serving hundreds of millions
of queries in a fraction of a second at a reasonable cost. To solve the
first problem, we perform an offline matrix computation to produce
PageRank, a query independent measure of page reputation, and combine
it with more traditional query-specific scoring. To solve the distributed
computing problem, we use tens of thousands of commodity PCs and highly
fault-tolerant software. I will discuss some details of these solutions,
and also share some interesting statistical tidbits about search and the
