The company E2V has developed a prototype device that uses a radio-frequency pulse to shut down a car’s engine at range, according to a report from the BBC. While the range of the device is fairly short, it worked on a handful of cars and motorbikes and could also potentially be used on boats.
A single bitcoin is now worth over $1,000, but the process of mining for the digital currency — in which people devote computing power to facilitate global Bitcoin transactions and secure the currency's network — is growing increasingly expensive. Serious miners have started to build dedicated facilities for the sole purpose of Bitcoin mining. Journalist Xiaogang Cao visited one such center in Hong Kong, the "secret mining facility" of ASICMINER, reportedly located in a Kwai Chung industrial building.
British artist Kyle Lambert spent quite a bit of time creating a digital painting and by the looks of it, it was time well spent. The drawing is an insanely realistic portrait of Morgan Freeman. The image you see above isn't a photo of Freeman photoshopped onto an iPad — that's Lambert's actual work of art.

In theory, Origami is simple: Take a sheet of paper, follow the dotted lines and without the use of scissors or glue, you’ve got a paper crane. It stands to reason that if you’re good at following instructions, you’re good at origami. And that’s true—anyone can fold their way to a simple paper crane. But truly grasping the geometric complexities of that crane? That’s actually pretty brainy stuff.
Somewhere between the turkey and the eggnog, someone in your family is almost certainly going to mention their plans to pick up a cheap tablet or TV set. Or maybe someone will bring up the nearest mall electronics store’s “amazing” deals on HDMI cables.
SuperUser reader KingNestor is curious about how much RAM a 64-bit computer can hold:
I’m reading through my computer architecture book and I see that in an x86, 32bit CPU, the program counter is 32 bit.
So, the number of bytes it can address is 2^32 bytes, or 4GB. So it makes sense to me that most 32 bit machines limit the amount of ram to 4gb (ignoring PAE).
Am I right in assuming that a 64bit machine could theoretically address 2^64 bytes, or 16 exabytes of ram?!
A $500 “nano-camera” that can operate at the speed of light has been developed by researchers in the MIT Media Lab.
The three-dimensional camera, which was presented last week at Siggraph Asia in Hong Kong, could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
The Federal Communications Commission will propose allowing passengers to use their cellphones on airplanes, setting up a debate that will pit the technically possible against the socially tolerable.
While phone use would still be restricted during takeoff and landing, the proposal would lift an FCC ban on airborne calls and cellular data use by passengers once a flight reached 10,000 feet.
Multi-millionaire investment manager, and world's first space tourist, Dennis Tito has been testifying before the US Congress about his plans for a 501-day trip around Mars and back.
He says he'll need government money to meet the planned schedule of a 2018 launch.
In a little booth tucked in the corner of the SC13 supercomputing conference here this week may be the next Intel.
There you'll find Max Shulaker, a Stanford University graduate student, ready to explain carbon nanotube digital circuits to anyone stopping by. Shulaker is part of team of researchers building such circuits, and will be presenting to attendees their research on "the first" computer built using carbon nanotubes, or CNTs.
