While P/NP is indeed pretty way offtopic here, P vs. NP doesn't necessarily apply solely to decision problems. Furthermore, many problems can be rephrased as decision problems; e.g. Does the cannonball need more than 10 second to complete its flight?

For a traditional P/NP example: the traveling salesman problem is about finding the shortest path, which is also not a decision problem.

According to KPN, the hacked website was not part of the CA's issuing system. Assuming they're being wholly truthful, this article is pure sensationalism: A company has a non-critical website that's hacked: whooptie.

Of course it's bad PR: it doesn't inspire confidence in their other security matters. However, its just as likely that they're concentrating on their actual business (managing certificates), and the site was an afterthought. In any case (maybe I'm just cynical) it doesn't surprise me that a very low traffic, low volume site is negligently secured.

Totally misleading headline.

Linux 3D Games Run Faster On PC-BSD 298

koinu writes "Phoronix has published benchmarks comparing 3D game performance on Ubuntu Linux 11.04 with the FreeBSD Linux ABI emulation on the 8.2 release of PC-BSD, which is a desktop variant of FreeBSD. Most results show that the emulated Linux layer on FreeBSD performs better than Linux natively. It's pretty interesting, because most people would expect that an additional abstraction layer would generally slow down the execution of binaries."
