swframe writes “A new object recognition system developed at MIT and UCLA looks for rudimentary visual features shared by multiple examples of the same object. Then it looks for combinations of those features shared by multiple examples, and combinations of those combinations, and so on, until it has assembled a model of the object that resembles a line drawing. Popular Science has a summary of the research. I’ve been working on something similar and I think this accomplishment looks very promising.”

I Don’t Believe in Imaginary Property writes “As of Winter Quarter 2010, UCLA professors will no longer be able to post videos on their course websites. Although they’ve long relied upon fair use protections for educational use, the Association for Information Media and Equipment has made claims that they’re copyright infringers, even though the videos are only available on campus and the students are allowed to watch the videos in the Instructional Media Lab. Even though they believe their use of the materials to be fair, the UCLA has decided to back down rather than face litigation. Many professors have commented that this will hurt students, because they now have to watch all videos at the IML, which isn’t open on weekends, forcing students to try to fit assigned videos between classes.”

elyons writes “Another neat discovery has come from the lab of Larry Lyons at UCLA. As reported earlier on Slashdot, Lyons’ group studies the dynamics of auroras. Their most recent discovery reveals for the first time the sequence of events leading to dramatic space-weather disturbances. Using a network of cameras deployed around the Arctic in support of NASA’s THEMIS mission, they recorded over 200 instances of auroras colliding, causing brilliant displays of northern lights (see time 8:22 for such an example).”

sean_nestor writes with this excerpt from The Register: “Some date the dawn of the net to September 12, 1969, when a team of engineers at the University of California, Los Angeles (UCLA) connected the first two machines on the first node of ARPAnet, the US Department of Defense-funded network that eventually morphed into the modern interwebs. But others — including Professor Leonard Kleinrock, who led that engineering team — peg the birthday to October 29, when the first message was sent between the remote nodes. ‘That’s the day,’ Kleinrock tells The Reg, ‘the internet uttered its first words.’ …A 50kbps AT&T pipe connected the UCLA and SRI nodes, and the first message sent was the word ‘log’ — or at least that was the idea. UCLA would send the ‘log’ and SRI would respond with ‘in.’ But after UCLA typed the ‘l’ and the ‘o,’ the ‘g’ caused a memory overflow on the SRI IMP. … ‘So the first message was “Lo,” as in “Lo and Behold,”‘ Kleinrock says. ‘We couldn’t have asked for a better message — and we didn’t plan it.’”
