suraj.sun sends this quote from Engadget about improving the Kinect 3D video recordings we discussed recently: "[Oliver Kreylos is] blowing minds and demonstrating that two Kinects can be paired and their output meshed — one basically filling in the gaps of the other. He found that the two do create some interference, the dotted IR pattern of one causing some holes and blotches in the other, but when the two are combined they basically help each other out and the results are quite impressive."

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

An anonymous reader writes "Microsoft's Bing search engine has a vulnerability with its cash-back promotion, which impacts both merchants and customers. In traditional Microsoft fashion, the company has responded to the author of the breaking Bing cash-back exploit with a cease & desist letter, rather than by fixing the underlying security problem. It is possible for a malicious user to create fake Bing cash-back requests, resulting in not only fake cash-back costs for the merchant, but also blocking legitimate customers from receiving their cash-back from Bing. The original post is currently available in Bing's cache, although perhaps not for long. But no worries, the author makes it clear that the exploit should be painfully obvious to anyone who reads the Bing cash-back SDK."
