British researchers design a million-chip neural network 1/100 as complex as your brain
If you want some idea of the complexity of the human brain, consider this: a group of British universities plans to link as many as a million ARM processors in order to simulate just a small fraction of it. The resulting model, called SpiNNaker (Spiking Neural Network architecture), will represent less than one percent of a human's gray matter, which contains 100 billion neurons. (Take that, mice brains!) Yet even this small scale representation, researchers believe, will yield insight into how the brain functions, perhaps enabling new treatments for cognitive disorders, similar to previous models that increased our understanding of schizophrenia. As these neural networks increase in complexity, they come closer to mimicking human brains -- perhaps even developing the ability to make their own Skynet references.
Palm CFO keeps cards, products, anything interesting close to the vest
We're not certain why Palm CFO Andy Brown was being so cagey about the company's next-gen Linux-based platform during a "fireside chat" at a recent JPMorgan tech conference, but his devotion to secrecy is almost as interesting as if he had dished out some details on upcoming devices. Wait, no, it's not. Of course, Palm's new OS is being developed by Jon Rubenstein, former Apple hardware and iPod veep, so maybe the paranoia is contagious -- but Brown probably didn't convince anyone when he openly compared Palm to Apple because both companies make both the hardware and the software. That's a pretty hard head-to-head to be in when you're talking about the Centro running Garnet -- maybe some actual products might help that pill go down easier, you know? Brown did say that we'd been seeing the fruits of all this labor sometime "this summer," but didn't mention what it might actually be -- let's hope it's got more design behind it than that nasty Zeppelin prototype.
