They found that the brain's complexity is beyond anything they'd imagined, almost to the point of being beyond belief, says Stephen Smith, a professor of molecular and cellular physiology and senior author of the paper describing the study:
"One synapse, by itself, is more like a microprocessor--with both memory-storage and information-processing elements--than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth."" top
B1oodAnge1 (1485419) writes "ZDNet reports that proof of concept code was released last week that exploits a vulnerability in both the 64 and 32 bit versions of the 2.6.30 and 2.6.18 Linux kernel to gain root access. Apparently this affects Red Hat Enterprise Edition 5, which uses the 2.6.18 kernel.
A vulnerability which, when viewed at the source level, is unexploitable!
But which, thanks to gcc optimizations, becomes exploitable:)
Also, bypass of mmap_min_addr via SELinux vulnerability!
(where having SELinux enabled actually increases your risk against a
large class of kernel vulnerabilities)
"The agreement with Sony Computer Entertainment covers tools and middleware for the PlayStation3. As a result, the binary version of the Nvidia PhysX technology software development kit (SDK) is available to registered PS3 developers for free download and use on the Sony Computer Entertainment developer network, Nvidia said in a statement."
Along with all newer Nvidia graphics cards now supporting PhysX, are we going to finally see a wider variety of games using this technology?"
B1oodAnge1 writes "According to ZDNet, 'In a bit of an awkward and highly unnecessary move, a team at the BBC's technology program "Click" has purchased a botnet consisting of 22,000 malware infected PCs, self-spammed themselves on a Gmail account, and later on DDoS-ed a a backup site owned by security company Prevx (with prior agreement), all for the sake of proving that botnets in general do what they're supposed to — facilitate cybercrime.'"
