Flywheel Bicycle with regenerative braking mechani->

Submitted by Anonymous Coward
An anonymous reader writes "Regenerative braking mechanisms are actually a new type of energy harvesting method used in vehicles to generates and stores energy everytime you apply brake.This technology has been around there and were used in motor sports but they were not popular until modern hybrid cars began to use it.Here is a similar kind of energy generation mechanism developed by Maxwell von Stein, a 22-year-old graduate of The Cooper Union.He brought the regenerative braking idea to a whole new level — on bicycles."

Facebook steals every number from your smartphone-> 1

Submitted by

destinyland writes "Facebook users discovered this week that every contact number stored on their smartphone may now also be stored on Facebook's servers. One technology site notes "numerous reports from users who claim to have never synchronized their contacts with Facebook's mobile apps, yet still find all of their contact data stored on Facebook's servers." Even if your friends don't have Facebook accounts, Facebook may still have their names and phone numbers. There's a six-click path through each user's "Account settings" which ultimately leads to a page for re-claiming your friends' phone numbers, and "There is probably a clause buried deep within Facebook's terms and conditions that makes this invasion of your privacy OK on paper," this article notes. "But odds are still pretty good that it's not OK with you.""

Researchers use accelerometer to keylog smartphone->

Submitted by
MrSeb
MrSeb writes "Two researchers from the University of California Davis, Hao Chen and Lian Cai, have successfully divined the keystrokes on an Android on-screen keyboard by measuring the wiggles, jiggles, and vibrations picked up by the device’s accelerometer. Every key has a unique pitch, roll and yaw fingerprint that can be identified, and the researchers use this data to accurately infer what the user is typing.

This is significant because the data from accelerometers is not thought of as a potential attack vector, and is thus freely available to any application on any smartphone or tablet. Accelerometer and gyroscope data is also available through the DeviceOrientation API which is present in almost every web browser, including Android 3.0 and iOS 4.2."

Fired IT workers claim discrimination ->

Submitted by dcblogs
dcblogs writes "Eighteen IT employees of Molina Healthcare Inc. who were laid-off after their jobs were offshored, have filed a lawsuit in California claiming they are victims of discrimination after they were replaced with foreign nationals, Indian workers from a outsourcing company. As the company's offshore engagement increased, Indian workers dominated the IT shop so much so that meetings sometimes shifted to an Indian language, which added to a growing sense of isolation among the Molina IT employees. When the IT workers were informed of their layoff at a mass meeting, they went on the attack. "We were being quite confrontational about why they are laying us off and keeping all these H-1B workers," said one of the fired IT professionals."

Understanding Spamming Bad Neighborhoods->

Submitted by Anonymous Coward
An anonymous reader writes "In the same way crime rates change according to the neighborhood in a city, malicious activities rates vary on the Internet depending on the subnet. In a recent study (PDF: http://eprints.eemcs.utwente.nl/20379/) to be presented at CNSM 2011 ( http://cnsm.loria.fr/ ), researchers of the University of Twente have investigated Spamming Bad Neighborhoods. They have showed that badhoods with more spammers are not necessarily the worst ones in terms of spam volume. In fact, 6 of the 10 most criminal badhoods had only 1 spammer. Their results also show that 10% of the badhoods were responsible for most of the spam, and they have identified the "most spam-friendly providers" (those that turn a blind eye to massive spammers ) and the "worst protected" badhoods (the ones with more malware)."

Swarmanoid Robots Work Together to Steal Books->

Submitted by Zothecula
Zothecula writes "Swarms of small, intercommunicating robots are now being eyed up for all sorts of potential uses, including the creation of communications networks for disaster relief, mapping out hazardous environments, or even perhaps helping with the colonization of Mars. Since 2007, a group of European research groups have been collaborating on the now-completed Swarmanoid project, in which a variety of purpose-specific mini robots where programmed to cooperate in order to accomplish a task. Although the bots have been perfecting their book-stealing routine since 2009, a video depicting the task won the Best Video award at last week's 2011 Artificial Intelligence Conference in San Francisco, and was many peoples' introduction to Swarmanoid."
