    Much faster than the Fast Fourier Transform if the signal's frequency content is sparse, which is commonly the case for many real signals.

    Yep, I was told already a few months ago from Storn that this is indeed the best adaptive DE ever made. It is already in the road map for pagmo 1.2. According to pagmo it humiliates CMAES !!!

    Analysis of a recent Java flaw exploited by the Flashback Trojan reveals that more than 550,000 Macs were affected in the U.S. and abroad, according to anti-virus vendor Doctor Web. "This once again refutes claims by some experts that there are no cyber-threats to Mac OS X," Doctor Web said in a Tuesday blog post. lol :)

  • A new form of encryption allows you to compute with data you cannot read
  • The technique that makes this magic trick possible is called fully homomorphic encryption, or FHE. It’s not exactly a new idea, but for many years it was viewed as a fantasy that would never come true. That changed in 2009, with a breakthrough discovery by Craig Gentry, who was then a graduate student at Stanford University. (He is now at IBM Research.) Since then, further refinements and more new ideas have been coming at a rapid pace.

    A new quasicrystal formation has been discovered using computer simulations. The formation consists of hard triangular bipyramids, each composed of two regular tetrahedra sharing a single face, and is described in a paper in Physical Review Letters by Sharon Glotzer and colleagues at the University of Michigan in the US. Great for Luis coming paper .....

INF hardware NRG energy data mining

shared by Luís F. Simões on 07 Nov 11 - No Cached
  • For Hewlett Packard Fellow Chandrakat Patel, there’s a “symbiotic relationship between IT and manure.”
  • Patel is an original thinker. He’s part of a group at HP Labs that has made energy an obsession. Four months ago, Patel buttonholed former Federal Reserve Chairman Alan Greenspan at the Aspen Ideas Festival to sell him on the idea that the joule should be the world’s global currency.
  • Data centers produce a lot of heat, but to energy connoisseurs it’s not really high quality heat. It can’t boil water or power a turbine. But one thing it can do is warm up poop. And that’s how you produce methane gas. And that’s what powers Patel’s data center. See? A symbiotic relationship.

  • Financial house Cantor Fitzgerald is interested in Project Moonshot because it thinks HP’s servers may have just what it takes to help the company’s traders understand long-term market trends. Director of High-Frequency Trading Niall Dalton says that while the company’s flagship trading platform still needs the quick number-crunching power that comes with the powerhog chips, these low-power Project Moonshot systems could be great for analyzing lots and lots of data — taking market data from the past three years, for example, and running a simulation.
