Submission + - Hidden Image Found in Da Vinci's Last Supper (telegraph.co.uk)

Tech.Luver writes: "Telegraph reports, " New claims that Leonardo da Vinci's The Last Supper contains a hidden image of a woman holding a child are provoking a storm of interest on the internet. The figure allegedly appears when the 15th Century mural painting is superimposed with its mirror image, and both are made partially transparent. According to Slavisa Pesci, an Italian amateur scholar, the resulting composite picture shows a figure clutching what appears to be a young child. ""

Submission + - objective rankings for CS departments

John Regehr writes: "Students, prospective students, and professors care about how their department is ranked relative to other departments. Current ranking schemes for computer science departments are subjective: they are compiled, for example, by asking department chairs to rank other departments. An alternative, objective way to rank research departments is the meta h index, which we have compiled for a number of computer science departments. The h index, a measure of productivity of an individual researcher, is "the number of papers with citation number higher or equal to h." So to have an h index of 5, one must have written 5 papers that are each cited at least 5 times. The meta h index, then, extends this idea to measure the number of researchers in a department with h index higher than or equal to h. Of course it is easy to find flaws in this way of measuring research departments, but it has the advantages of being simple and of having no parameters to tune. Also, perhaps surprisingly, the meta h index correlates rather well with the ranking produced by US News."

Penguin Car Earns Indy500 Spot 244

strredwolf writes "Despite generating over $12K in funds, well short of the $250K goal, the Tux 500 Project was able to secure a spot in the Indy 500 with driver Roberto Moreno piloting the Linux #77 Indy car. He's back in the pack in 31st place (only 5.5 MPH separates 31st place from 1st) but was able to secure it by re-qualifying with an average speed of 220.299 MPH. Will Moreno be able to pilot the penguin-tipped Indy car to victory next week at the 91st Indianapolis 500?"
