SpaceSlug writes "The world's largest digital camera is to be used to keep an eye out for asteroids heading towards Earth. The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) has been built by researchers at MIT's Lincoln Lab. At its heart is a 1.4 billion pixel (or 1400 megapixel) camera that will scan the night sky looking for rogue near-Earth objects from atop Mount Haleakala in Maui Island, Hawaii. The system uses something called an orthogonal transfer CCD to remove atmospheric blur from images."

Last July, a research team from the University of Washington released an online tool to analyze whether web pages were being altered during the transit from web server to user. On Wednesday, the team released a paper at the Usenix conference analyzing the data collected from the tool. The found, unsurprisingly, that ISPs were indeed injecting ads into web pages viewed by a small number of users. The paper is available at the Usenix site. From PCWorld: "To get their data, the team wrote software that would test whether or not someone visiting a test page on the University of Washington's Web site was viewing HTML that had been altered in transit. In 16 instances ads were injected into the Web page by the visitor's Internet Service provider. The service providers named by the researchers are generally small ISPs such as RedMoon, Mesa Networks and MetroFi, but the paper also named one of the largest ISPs in the U.S., XO Communications, as an ad injector."
