Watch IBM's Watson On Jeopardy Tonight 293

JohnMurtari notes that the media hype machines are massively promoting tonight's battle between Jeopardy champions and a super computer. Yes it's a PR stunt. But I imagine the actual research probably had a lot of interesting problems to address. Anyway, you can learn about IBM Watson if you're interested. I'm sure the most amusing bits will be on YouTube about 30 seconds after air time.

Geostationary GPS Satellite Galaxy 15 Out of Control 379

Bruce Perens writes "The Galaxy 15 commercial satellite has not responded to commands since solar flares fried its CPU in April, and it won't turn off. Intelsat controllers moved all commercial payloads to other birds except for WAAS, a system that adds accuracy to GPS for landing aircraft and finding wayward geocaches. Since the satellite runs in 'bent pipe' mode, amplifying wide bands of RF that are beamed up to it, it is likely to interfere with other satellites as it crosses their orbital slots on its way to an earth-sun Lagrange point, the natural final destination of a geostationary satellite without maneuvering power."

Appeal For Commuter GPS Logs To Aid Electric Cars 144

holy_calamity writes "A team at Carnegie Mellon University has begun a project seeking to design a kit to cheaply convert secondhand cars into cheap, electric ones suitable for commuting, if little else. They hope to rely heavily on smart management software to extract as much efficiency as possible from regenerative braking, and knowledge of terrain from GPS tracking. But they are hampered by a lack of public data on how commuters actually drive. Their solution is to appeal to GPS users to upload .gpx log files of their commute to the team's site. The data is plugged into a simulator that reveals how much cheaper an electric car could do your journey, and an anonymized public dataset will be created. A programming contest will award a production electric car to the coder who designs the best management algorithm using it."

Google Street View Wants You to Direct New Tricycle Imager 115

An anonymous reader writes "Google is taking suggestions for where you'd like to see the new Street View Trike go. Your favorite park, hiking trail, zoo, school campus hangout or outdoor mall could be going online thanks to Google Street View's new 250 pound tricycle, complete with camera and GPS. According to the press release: 'The Street View trike began as a 20% project by Daniel Ratner, a Senior Mechanical Engineer on the Street View team. "I began thinking about building a bicycle-based Street View system after realizing how many interesting places around the world — ranging from historic landmarks to beautiful trails to shopping districts — aren't accessible by car," says Dan. "When I'm riding the trike, so many people come up to me and ask where it's off to next or how they can get imagery of their favorite spot, so I can't wait to see what our users come up with."'"

IBM Building 20 Petaflop Computer For the US Gov't 248

eldavojohn writes "When it's built, 'Sequoia' will outshine every super computer on the top 500 list today. The specs on this 96 rack beast are a bit hard to comprehend as it consists of 1.6 million processors and some 1.6TB of memory. That's 1.6 million processors — not cores. Its purpose? Primarily to keep track of nuclear waste & simulate explosions of nuclear munitions, but also for research into astronomy, energy, the human genome, and climate change. Hopefully the government uses this magnificent tool wisely when it gets it in 2012."
