For the first time, a commercially available quantum computer has been pitted against an ordinary PC – and the quantum device left the regular machine in the dust.
The bitcoin network speed estimate on bitcoinwatch.com passed 1 exaFLOPS (1,000 petaFLOPS) this week - over 8 times the combined speed of the top 500 supercomputers.

IBM announced this past November that its Blue Gene/Q Sequoia supercomputer could clock 16 quadrillion calculations per second, and could crudely simulate more than 530 billion neurons. What they did not advertise though, is that to do this, Blue Gene consumes nearly 8 megawatts, enough to power 160,000 homes. Boahen has now developed a new computing platform he calls Neurogrid, that runs around 100,000 times more efficiently. Each Neurogrid board, running at 5 watts, can simulate detailed neuronal activity of one million neurons — and it can now do it in real time.
I needed a couple of new GPU's for the computers in the house... but this was ridiculous.
Some questions I have that have absolutely nothing to do with beer.
If you, like us, once relished walking a video store's aisles and picking up giant VHS clamshell cases of ridiculous-looking sci-fi action movies with titles like Hell Comes to Frogtown, Immortal Combat or Ghost Warrior, you're going to get a massive smile pressing play on the trailer for Far Cry 3: Blood Dragon.
I know, I know, you are probably thinking oh no not again. However, most articles on this subject seem to be very biased towards Python, using flawed arguments that do more to expose the author’s lack of understanding of Perl rather than shedding any new light on the subject. Hopefully this article will do better and help redress the balance

The Hybrid Memory Cube Consortium, which consists of such silicon luminaries as Micron, Samsung, and IBM (but not Intel), has finally finished hammering out the Hybrid Memory Cube 1.0 standard. The HMC is a complete paradigm shift away from conventional DDR1/2/3 SDRAM, offering up to 15 times the performance of DDR3, while using 70% less energy. Just to whet your appetite, HMC 1.0 has a max bandwidth of 320GB/sec to a nearby CPU or GPU – PC3-24000 DDR3 SDRAM, on the other hand, maxes out at just 24GB/sec.
There’s a “Perl is Dead” meme floating around. It’s been around for a while, long enough that it’s picked up steam and plows along despite all evidence to the contrary. It’s so common, I won’t bother providing links, because you’ve seen more of them than I can count. It’s so common, I even heard it recently from a young MBA graduate, who was so entirely non-technical that he didn’t even know what HTML and CSS were, while working in sales for a web startup. But, he knew what Perl was, and he “knew” it was dead. Weird, but that’s how memes work. So, how did this meme start?
PHP is an embarrassment, a blight upon my craft. It’s so broken, but so lauded by every empowered amateur who’s yet to learn anything else, as to be maddening. It has paltry few redeeming qualities and I would prefer to forget it exists at all.
The cyber attack used against south korea recently has a component that targets *nix machines and wipes them. Only if the infected windows machine has mRemote setup with root access to the *nix machine, which is the kind of stupidity that deserves to be punished
It’s an immensely exciting time for anyone interested in small form factor hardware. Whether you’re gaming and performance focused or interested in gear perfect for an HTPC, there’s plenty of new stuff arriving on shelves at the moment.

Even though dual, quad, and octo-core CPUs have been around for a while, it's a far cry from truly massive parallel computing platforms. The chip manufacturer Adapteva is looking to put dozens of CPUs in a small package with their Parallella project.
The real-world tests are stunning. Not only does Calxeda’s array of “wimpy” cores outperform Xeon processors in web server tests, it beats them in both raw performance and performance-per-watt. De Gelas writes that “the Calxeda’s ECX-1000 server node is revolutionary technology.” After seeing the performance figures, I agree. There’s a place for ARM products in the datacenter. This also makes AMD’slong-term bet on an ARM server solution look like a good idea.
Nanophotonics researchers at Arizona State University have created the world’s first electrically powered room-temperature nanolasers. These lasers are the single most important step towards building computer chips that use light instead of electricity for ultra-fast and efficient on- and off-chip communications.

With much fanfare, eminent brain scientist Miguel Nicolelis recently declared that the brain is not computable. What does it really mean to ask if the brain is computable, and why do we care?

Feb. 28, 2013 — Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart -- one in Durham, N.C., and one in Natal, Brazil.

Michael Dell is buying back the personal computer manufacturer he founded and that carries his name for $24.4bn (£15.5bn).
Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing.
What you're looking at here is a piezoelectric cooling device, called a DCJ. By rapidly vibrating, it can force jets of cool air over hot surfaces quietly and efficiently, and GE says that it'll soon be taking the place of noisy, dirty, power-sucking fans in laptops and other electronics.
The cooler works by rapidly expanding and contracting in response to electricity. It's really just two flat plates, and when the plates expand, they suck in cool air at the sides. Contracting forces the air out the front. Do this a hundred times a second, and you've got a very small, very flat (the size of two quarters) cooling solution. In fact, it's 50% smaller than a traditional fan, and it operates nearly silently while consuming half the amount of power to move the same amount of air. Sold!
In a rare showing of bipartisanship, the House unanimously passed a resolution to ban UN regulation of the internet at the hands of the ITU (International Telecommunication Union).

After the US and Israel cooked up Stuxnet—a potent cyber weapon aimed at Iran's nuclear facilities—whenever a virus targets Iran, it could be something major. This time around, the web threat wants to erase Iranian banks.
