Cars powered by electricity are going to be cheaper to run per mile than gasoline cars, which provides some comfort to electric vehicle buyers.

The key question for the auto industry is what happens in a few years after the early adopters, the people willing to pay more for new technology and a greener ride, already have their EVs. Here, the economics of fueling and daily driving patterns loom much larger in the decision.

By itself the mere existence of this settlement portal wouldn't really be newsworthy, but this changed when we realized that they had copied it from a competitor.

Instead of coding the site themselves, they had simply copied the code (including the copyright statement) and images from a company in the same line of work.

They are so incompetent and probably blinded by the dollar signs in their eyes, that they can't even put a website together without breaking the law themselves - copyright law.

Exploiting bugs in two different ATM machines, the researcher from IOActive was able to get them to spit out money on demand and record sensitive data from the cards of people who used them.

After experimenting with his own machines, Jack developed a way of bypassing the remote authentication system and installing a homemade rootkit, named Scrooge, that lets him override the machine's firmware.

The machines Jack hacked were, however, based on Microsoft's Windows CE operating system.

Ron Bowles used a piece of code to scan Facebook profiles, collecting data not hidden by the user's privacy settings.

Mr Bowles said he published the data to highlight privacy issues, but Facebook said it was already public information.

Earlier this year there was a storm of protest from users of the site over the complexity of Facebook's privacy settings. As a result, the site rolled out simplified privacy controls.

The document - from May 30, 2007 - claims that insurgents shot down a Chinook transport helicopter over Helmand Province with a surface-to-air missile, or SAM. But a spokesman for the NATO command in Afghanistan, U.S. Army Col. Wayne Shanks, tells Danger Room, "We have no reports of any aircraft being damaged by SAMs."

Easily fired by infantry or a guy on a flatbed truck, MANPADs are capable of locking on to the heat generated by an aircraft within distances of around 6 miles, meaning that helicopters and low-flying fixed-wing aircraft are vulnerable - as are all aircraft at takeoff and landing.
