Georgia Institute of Technology Researchers Bridge the Airgap 65

An anonymous reader writes Hacked has a piece about Georgia Institute of Technology researchers keylogging from a distance using the electromagnetic radiation of CPUs. They can reportedly do this from up to 6 meters away. In this video, using two Ubuntu laptops, they demonstrate that keystrokes are easily interpreted with the software they have developed. In their white paper they talk about the need for more research in this area so that hardware and software manufacturers will be able to develop more secure devices. For now, Farraday cages don't seem as crazy as they used to, or do they?

Brain Implants Get Brainier 45

the_newsbeagle writes "Did my head just beep?" wonders a woman who just received a brain implant to treat her intractable epilepsy. We're entering a cyborg age of medicine, with implanted stimulators that send pulses of electricity into the brain or nervous system to prevent seizures or block pain. The first generation of devices sent out pulses in a constant and invariable rhythm, but device-makers are now inventing smart stimulators that monitor the body for signs of trouble and fire when necessary.

Anonymous No More: Your Coding Style Can Give You Away 213

from the leaving-your-mark dept.
itwbennett writes Researchers from Drexel University, the University of Maryland, the University of Goettingen, and Princeton have developed a "code stylometry" that uses natural language processing and machine learning to determine the authors of source code based on coding style. To test how well their code stylometry works, the researchers gathered publicly available data from Google's Code Jam, an annual programming competition that attracts a wide range of programmers, from students to professionals to hobbyists. Looking at data from 250 coders over multiple years, averaging 630 lines of code per author their code stylometry achieved 95% accuracy in identifying the author of anonymous code. Using a dataset with fewer programmers (30) but more lines of code per person (1,900), the identification accuracy rate reached 97%.

I thought the included (pre-installed) Microsoft Windows Defender (or Windows Security Essentials) was already good enough.

That, plus not installing every stupid piece of malware-studded "freeware" I come across and being a bit conservative in my browsing, has always been enough since Windows 7.

Windows after 7 also has a built-in software firewall, so wouldn't seem like you'd need one of those either.

I just can't picture needing anything beyond that.

The first rule of business economics club is never talking about business economics club.

The second rule of business economics club is that you never take all costs into consideration. As much as possible, make those someone else's problem: your minions', your successor's, another division's, the great big greater economy, the ecology, whatever. But keep all the success/credit/profit for yourself.

Then cash out and find another place to pillage.

Yes, business economics club is kind of like piracy, but more boring and venial.

I see later down in this discussion that the engine steering is done with pressurized fuel, which is presumably then dumped into the exhaust stream to burn. And the other actuators are too far from there to make it practical to extend the fuel-based hydraulic system to them.

Weird set of engineering compromises, but they make sense. Too bad about underestimating the capacity needed for the upper hydraulic reserve.
