Submission + - Scientists break the speed of light? (

pedramnavid writes: ...two German physicists claim to have forced light to overcome its own speed limit using the strange phenomenon of quantum tunnelling, in which particles summon up the energy to cross an apparently uncrossable barrier. Their experiments focused on the travel of microwave photons — energetic packets of light — through two prisms. When the prisms were moved apart, most photons reflected off the first prism they encountered and were picked up by a detector. But a few appeared to "tunnel" through a gap separating them as if the prisms were still held together. Although these photons had travelled a longer distance, they arrived at their detector at the same time as the reflected photons. This suggests that the transit between the two prisms was faster than the speed of light.

Dr Gunter Nimtz, of the University of Koblenz, told the magazine New Scientist: "For the time being, this is the only violation of special relativity that I know of."


Submission + - New Tool Automates Webmail Account Hijacks (

An anonymous reader writes: A pair of software tools demonstrated at the Black Hat security conference today automate the interception of cookie files transmitted over a wireless network that allow attackers to hijack accounts for Gmail, Hotmail, Facebook and a number of other Web 2.0 services,'s Security Fix reports. From the story: "the attack works even if victims subsequently change their passwords, or actively sign out of their accounts. However, attackers would be unable to change the victim's password, as all of the above-named services force the user to reenter the current password before changing it to a new one."

Judge Permits eBay's "Buy It Now" Feature 139

stalebread points to a Reuters story reporting that a federal judge refused to issue an injunction against eBay's "Buy It Now" feature. Quoting: "Judge Jerome B. Friedman of Federal District Court denied a motion by the Virginia company, MercExchange, for a permanent injunction to stop eBay from using the feature. The Supreme Court ruled last year that, although eBay infringed upon MercExchange's patent for the service, it was up to the lower court to decide whether eBay had to stop using it. 'MercExchange has utilized its patents as a sword to extract money rather than as a shield to protect its right to exclude or its market share, reputation, good will, or name recognition, as MercExchange appears to possess none of these,' he wrote."

Submission + - Abuse??? What abuse?

An anonymous reader writes: Last Friday I opened an account on the website of a large company (herein referred to as xx). From the beginning, I was unable to complete a normal transaction, so I wrote to the customer service department asking for assistance in getting started. The response came the next day: Abusing xx — Your xx account has been suspended ... your account was acting inconsistently with the letter or spirit of our policies. Somewhat flabbergasted, I wrote asking what on earth this was about. A brief but intense email correspondence ensued, with two principal issues neither of which could be successfully addressed: the company refuses to give any information as to the nature of the alleged violation, and refuses to consider reinstating the account. The only further detail I could obtain was that the nature of the complaint is such that restoring service is not considered an option. Given this kind of treatment, the latter may be no great loss; but still, in the interest of protecting my good name, I'd like to ask if there are people out there who've had similar experiences, and what, if anything, they did about them.

Submission + - "Bong Hits 4 Jesus" student loses SCOTUS r (

Fudgefactor7 writes: The U.S. Supreme Court ruled 5-4 Monday that students can face limits on their rights to free speech. Schools can rein in students' speech if it can be interpreted as promoting illegal drug use, Chief Justice John Roberts wrote in the court's opinion. The case stemmed from an incident in January 2002 in which a crowd of students, townspeople and teachers gathered on a public street in Alaska across from a high school to watch the Olympic torch relay pass in front of them as part of a parade in support of the upcoming Winter Olympic Games. Student Joseph Frederick wanted to make a statement about his First Amendment rights in front of the television crews covering the event. As the crowd thickened, he unfurled a banner with the message "Bong Hits 4 Jesus."
