writes For the first time, scientists have taught computers to figure out the direction of time in videos, a result that could help researchers better understand our own perception of time. Regardless of any possible applications, "we just thought it was a great problem," says one of the study's authors. Teaching computers to see the arrow of time combines computer science, physics, and human perception to get at the heart of the question, "How do we understand the visual world?"
The researchers "broke down 180 YouTube videos into square patches of a few hundred pixels, which they further divided into four-by-four grids. Combining standard techniques for discovering objects in still photographs with motion detection algorithms, the researchers identified 4000 typical patterns of motion, or 'flow words,' across a grid’s 16 cells. ... When they tested their program on the remaining 60 videos, the trained computers could correctly determine whether a video ran forward or backward 80% of the time

Last fall, Newegg lost a case
against patent troll TQP for using SSL with RC4, despite arguments from Diffie of Diffie-Hellman key exchange
. Intuit was also targeted by a lawsuit for infringing the same patent, and they were found not to be infringing
. mpicpp (3454017)
sends this excerpt from Ars: U.S. Circuit Judge William Bryson, sitting "by designation" in the Eastern District of Texas, has found in a summary judgment ruling (PDF) that the patent, owned by TQP Development, is not infringed by the two defendants remaining in the case, Intuit Corp. and Hertz Corp. In a separate ruling (PDF), Bryson rejected Intuit's arguments that the patent was invalid.
Not a complete victory (a clearly bogus patent is still not invalidated), but it's a start.Read Replies (0)

writes in with news about a new dating opportunity for Mensa members. It takes a special person to join Mensa. For one, the elite society only takes individuals with IQ scores in the 98th percentile, meaning just 1 in 50 Americans is eligible. This exclusivity — some might say snobbery — is part of Mensa's lore. Early Mensans in Britain walked around with yellow buttons, organizational publications once referred to non-Mensa members as "Densans," and last year, a top Mensa member and tester called anyone with an IQ of 60 a "carrot." In short, you don't always join Mensa because you think you're smart. You join to be set apart from most people, who are, as one member put it: "mundane." But a new partnership between American Mensa and online dating giant Match.com offers a new, enticing reason to join the society of geniuses: true love. Beginning this week, members of the brainiac group can connect through a separate, exclusive dating service called Mensa Match. In addition, Match.com members can add a special Mensa badge to their profiles, signaling a specific interest in connecting with a single person with a confirmed genius-level IQ score.Read Replies (0)
