An anonymous reader writes "A teenager found in possession of a stolen bicycle was given probation, with a whole bunch of computer-related restrictions. He wasn't allowed to use social networks or instant messaging. He wasn't allowed to use a computer that had 'encryption, hacking, cracking, scanning, keystroke monitoring, security testing, steganography, Trojan or virus software.' The kid appealed, noting that the restrictions on social networking seemed overly broad, and restricting him from using a computer with a virus was difficult since viruses and trojans and the like tend to try to stay hidden, so he might not know. While the court overturned the restrictions on social networking, and changed the terms of computer restrictions to include the word 'knowingly,' it did keep the restriction on against using any computer with encryption software. Remember, this isn't someone convicted of malicious computer crimes, but of receiving a stolen bicycle. So why is perfectly reasonable encryption software not allowed? And what computer these days doesn't have encryption software?"

Explore the architecture of Ceph and learn how it provides fault tolerance and simplifies the management of massive amounts of data."

New York State's Attorney General, Andrew Cuomo, has subpoenaed a number of online retailers, including GameStop, Barnes & Noble, Ticketmaster and Staples, over the way they pass information to marketing firms while processing transactions. MSNBC explains the scenario thus: "You're on the site of a well-known retailer and you make a purchase. As soon as you complete the transaction a pop-up window appears. It offers a discount on your next purchase. Click on the ad and you are automatically redirected to another company's site where you are signed up for a buying club, travel club or credit card protection service. The yearly cost is usually $100 to $145. Here's where things really get smarmy. Even though you did not give that second company any account information, they will bill the credit or debit card number you used to make the original purchase. You didn't have to provide your account number because the 'trusted' retailer gave it to them for a cut of the action." While there is no law preventing this sort of behavior, Cuomo hopes the investigation will pressure these companies to change their ways, or at least inform customers when their information might be shared.

eldavojohn writes "MIT researchers have built and demonstrated the first room-temperature germanium laser that can produce light at wavelengths suited for communication. This achievement has two parts: '[U]nlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data — and maybe even perform calculations — using light instead of electricity. But more fundamentally, the researchers have shown that, contrary to prior belief, a class of materials called indirect-band-gap semiconductors can yield practical lasers.' While these are only the initial steps in what may become optical computing devices, the article paints it as very promising. The painful details will be published in the journal Optics Letters."
