Raytheon software trolls social networks Raytheon, a Massachusetts defense contractor, has built tracking software that pulls information from social networks, according to a video obtained by the Guardian newspaper in London. The Massachusetts-based company has acknowledged the technology was shared with U.S. government and industry as part of a joint research and development effort, in 2010, to help build a national security system capable of analyzing 'trillions of entities' from cyberspace. The video obtained by the newspaper starts with a demonstration by Raytheon's "principal investigator," Brian Urch, showing how easy it is to track an employee named Nick - a real person - based on all the places he has checked in using his smartphone. "When people take pictures and post them on the Internet using their smartphones, the phone will actually embed the latitude and longitude in the header data - so we're going to take advantage of that," Urch says. Square will handle point-of-sale systems for Blue Bottle's 11 outlets, starting with the stores in San Francisco's Mint Plaza, in Oakland and in Brooklyn, N.Y. Customers at those three outlets can immediately start using the Square Wallet mobile phone app to buy coffee or gift cards. Blue Bottle's reach is just a sliver of the more than 7,000 U.S. Starbucks locations that now accept payment through Square, but revenue for the San Francisco company -with its office in The Chronicle's building - has also been growing through deals with several other smaller regional chains.
