Yeah, me too. The only time I read the main page is when I'm at a public computer and have to actually type the address.

But I did, sir. Didn't notice the pg. 2 bit.

You call encryption tin-foil-hattery? Blasphemer!

I wouldn't necessarily call this a "bank," actually. I'd rather define it as an investor's pool, or a mutual fund.

From slashdot:
"European researchers have taken a step towards replicating the functioning of the brain in silicon, creating new custom chip with the equivalent of 200,000 neurons linked up by 50 million synaptic connections. The aim of the Fast Analog Computing with Emergent Transient States (FACETS) project is to better understand how to construct massively parallel computer systems modeled on a biological brain. Unlike IBM's Blue Brain project, which involves modeling a brain in software, this approach makes it much easier to create a truly parallel computing system. The set-up also features a distributed algorithm that introduces an element of plasticity, allowing the circuit to learn and adapt. The researchers plan to connect thousands of chips to create a circuit with a billion neurons and 10^13 synapses (about a tenth of the complexity of the human brain)."

Perhaps I'm a bit confused here, but how are they to know their developmental progress without a complete understanding of all the actions and functions of the neuron & synapse? It seems like a chicken vs. egg scenario.

My feeling is that if you research from both fronts simultaneously, one will help understand the other, and in some time the two ends will meet and give you the whole picture. If they say like "our current theory is that the brain works this way" and model that behavior on their artificial setup, they can see what they got right and wrong faster than by looking at the brain. Makes sense?

I was referring to the specific quotes I'd pulled: If they don't have a true simulation, then how more/less powerful than the human brain are their systems? They claim it's 100,000 times faster than the brain, but aren't performing all its duties.

Hey tone... obviously it's all nonsense in that respect. I mean, we don't know exactly enough what a neuron does. but the 100,000x is refering to the propagation speed between neurons... signals in the brain are slow, they can be a lot faster on a chip like this... but you are correct, it's a meaningless comparison and I wish people would stop doing it for the benefit of the mass media.
Note, that when I say this I am not saying anything about the project itself, just the media representation of the project as a "brain". It's a biologically inspired processor, if anything, but I think it can really help us with understanding how to use that massive parallelism to perform useful functions which will in turn help with AI research. And as KBlack said, possibly help the neuroscience at the other end of the spectrum understand how the brain is capable of doing some things.

Something that probably deserves a front page article: Canadian researchers uncover Chinese cyber spy network. They're calling it the GhostNet.
He's the PDF on what they found: Tracking GhostNet: Investigating a Cyber Espionage Network.
| Quote: | Key fndings:
•Documented evidence of a cyber espionage network infecting at least 1,295 computers in 103 countries, of which close to 30% can be considered as high-value diplomatic, political, economic, and military targets.
•Documented evidence of penetration of computer systems containing sensitive and secret information at the private offces of the Dalai Lama and other Tibetan targets.
•Documentation and reverse engineering of the modus operandi of the
GhostNet system—including vectors, targeting, delivery mechanisms, data retrieval and control systems—reveals a covert, diffcult-to-detect and elaborate cyber-espionage system capable of taking full control of affected systems. |
