An anonymous reader writes "University of Wahington TV Presents "behind the Scenes With Google." From the site : '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.' "
