Google: A Behind-the-Scenes Look

(This is a 55:39 minute video presentation)

Search is one of the most important applications used on the internet
and poses some of the most interesting challenges in computer
science. Providing high-quality search requires understanding across
a wide range of computer science disciplines. In this program, Jeff
Dean of Google describes some of these challenges, discusses
applications Google has developed, and highlights systems they've
built, including GFS, a large-scale distributed file system, and
MapReduce, a library for automatic parallelization and distribution
of large-scale computation. He also shares some interesting
observations derived from Google's web data.
