Hugh Pickens DOT Com writes "Tom Simonite reports at MIT Technology News that a new research group within Facebook is working on an emerging and powerful approach to artificial intelligence known as deep learning, which uses simulated networks of brain cells to process data. Applying this method to data shared on Facebook could allow for novel features, and perhaps boost the company's ad targeting. Deep learning has shown already potential to enable software to do things such as work out the emotions or events described in text even if they aren't explicitly referenced, recognize objects in photos, and make sophisticated predictions about people's likely future behavior. Facebook's chief technology officer, Mike Schroepfer, says that one obvious place to use deep learning is to improve the news feed, the personalized list of recent updates he calls Facebook's 'killer app.' Facebook already uses conventional machine learning techniques to prune the 1,500 updates that average Facebook users could possibly see down to 30 to 60 that are judged to be most likely to be important to them. 'The data set is increasing in size, people are getting more friends, and with the advent of mobile, people are online more frequently,' says Schroepfer. 'It's not that I look at my news feed once at the end of the day; I constantly pull out my phone while I'm waiting for my friend, or I'm at the coffee shop. We have five minutes to really delight you.'"Read Replies (0)

cold fjord writes with this Business Week report: "LinkedIn Corp. ... was sued by customers who claim the company appropriated their identities for marketing purposes by hacking into their external e-mail accounts and downloading contacts' addresses. The customers, who aim to lead a group suit against LinkedIn, asked a federal judge in San Jose, California, to bar the company from repeating the alleged violations and to force it to return any revenue stemming from its use of their identities to promote the site ... 'LinkedIn's own website contains hundreds of complaints regarding this practice,' they said in the complaint filed Sept. 17. ... LinkedIn required the members to provide an external e-mail address as their username on its site, then used the information to access their external e-mail accounts when they were left open ... 'LinkedIn pretends to be that user and downloads the e-mail addresses contained anywhere in that account to LinkedIn's servers,' they said. 'LinkedIn is able to download these addresses without requesting the password for the external e-mail accounts or obtaining users' consent.'"
"This puts an interesting twist on LinkedIn's recent call for transparency

R3d M3rcury writes with the story that "NASA and Boeing, along with other nations, are studying the feasibility of keeping the International Space Station in orbit until 2020
and possibly until 2028 — the 30 year anniversary of the launch of the first module." From the article: "To assess the long-term structural health of the station, Boeing engineers developed detailed computer models based on NASA's projected use -- the expected stresses caused by future dockings, reboosts, crew activity and thermal cycles -- and combined that with actual data from on-board accelerometers and strain gauges. ... "What we're looking at is theoretical crack growth," Pamela McVeigh, the engineer in charge of the Boeing structural analysis in Houston, told CBS News. "So the failure mode would be you'd have a crack beginning, probably (at) a bolt hole, and the crack would grow to another edge. So you'd lose like a flange on a C-beam, or an I-beam. The stiffness of your structure would then change, the bolt hole you that you were growing the crack out of, now that bolt wouldn't be effective."Read Replies (0)

Taco Cowboy writes "'NASA is calling off attempts to find its Deep Impact comet probe after a suspected software glitch shut down radio communications in August, officials said on Friday.' Last month, engineers lost contact with Deep Impact and unsuccessfully tried to regain communications. The cause of the failure was unknown, but NASA suspects the spacecraft lost control, causing its antenna and solar panels to be pointed in the wrong direction. NASA had hoped Deep Impact would play a key role in observations of the approaching Comet ISON, a suspected first-time visitor to the inner solar system that was discovered in September 2012 by two Russian astronomers. The comet is heading toward a close encounter with the sun in November, a brush that it may not survive."
Deep Impact has had a pretty good run, though: from its original mission to launch a copper slug at a comet
(hence the name), to looking for Earth-sized planets
