Luiz Barroso talks about the concept of Energy Proportional computing and how he thinks DRAM and disk manufacturers could do a better job creating devices consume energy in proportion to the computing to perform. Barroso and Holzle analyzed 5000 servers at Google over six months and found the average CPU utilization was between 15-45% - the region in which a computer operates the least efficiently. At issue is the fact that most manufacturers maximize efficiency to SPECpower which assumes that the computer is running at 100% utilization.
Search engine indexers are aware of (X)HTML and know what to look for when indexing those documents, but if the indexers were tuned to look for RDFa and WAI-ARIA Roles, would the semantics of the document be quite so important? If arbitrary XML on the web is ever going to happen then machine-readable annotations will be an important driving factor for content indexing, and the explosion in client-side XSLT that will follow.
Big Buck Bunny is 3d animated movie created entirely with open source software.
Schema design may seem an odd candidate for consideration as an agile technology, yet with a slight change of emphasis (from agile "development" to agile "design") agile techniques can actually make schema development reasonable and even ... fun.
Brian Cox talks about the scientific and technical challenges as well as some of the LHC-related computing efforts. Cox makes the case for the importance of continued commitment to pure scientific research calling the LHC the Earth's "first Apollo Mission of the 21st Century". He compares life as a rock star to life as a high-energy physicist, and debunks some of the FUD surrounding the possible creation of black holes. The Large Hadron Collider will collide up to 600 million protons every second, and it will produce 2 GB of data every 10 seconds requiring a globally distributed network of petabyte-scale storage and thousands of CPUs.
