Subject: Cracking Siri Message-ID: <firstname.lastname@example.org> Cracking Siri On October 14, 2011, Apple introduced the new iPhone 4S. One of its major new features was Siri, a personal assistant application. Siri uses a natural language processing technology to interact with the user. Interestingly, Apple explained that Siri works by sending data to a remote server (that's probably why Siri only works over 3G or WiFi). As soon as we could put our hands on the new iPhone 4S, we decided to have a sneak peek at how it really works. Today, we managed to crack open Siri's protocol. As a result, we are able to use Siri's recognition engine from any device. Yes, that means anyone could now write an Android app that uses the real Siri! Or use Siri on an iPad! And we're goign to share this know-how with you. ... http://applidium.com/en/news/cracking_siri/

Subject: Paying by smartphone Message-ID: <HsuWk.A.eoC.-XrwOB@telecom> >Is your wallet the next relic of the digital age? Why pay with cash >or plastic when you can use a smartphone? > >That is what Ainsley Onstott did on a recent afternoon in Cambridge's >Kendall Square. She simply showed her iPhone to pay for a sandwich at >Sebastians Cafe. "They scan it, and I get my receipt e-mailed to >me,'' said Onstott, 26, a special events manager at the American >Heart Association. For the dubious convenience of paying by smartphone (in lieu of cash) for a sandwich, all you have to do is turn over your mobile phone number, email address, and credit card or bank account info. I can't understand people rushing to give up so much private information for so little benefit. -Ed

And the effects don't have to be ionizing to affect human brain cells, which utilize several hundred thousand different organically catalysed (sub electron volt) chemical reactions. But most of the older phones ran in 800-900Mhz range.. Where wavelength is double to triple that of modern phones. Thus maximum field strength for these older phones was lower by a wavelength cubed function. > >I do wonder how much the "experts" in human physiology that create >these reports are also expert in the changing nature of the radiation >sources they are studying?

Subject: For Tech's Elite, Mobile Gaming Is a Big Play Message-ID: <email@example.com> For Tech's Elite, Mobile Gaming Is a Big Play Best and Brightest See the Sector as Chance for Fun and Massive Payoff By JOSEPH WALKER NOVEMBER 15, 2011 Mobile gaming is the new frontier. After Aadil Mamujee graduated from Harvard Business School in 2010, he could have worked anywhere. Rather than join a hedge fund or consulting firm though, he signed up with a small, San Francisco gaming start-up best known for "Tap Pet Hotel," an iPhone videogame that lets users build hotel rooms for animated puppies and pandas. It wasn't a passion for videogames that sent Mr. Mamujee, 29 years old, to Pocket Gems Inc. The Cambridge University-trained engineer saw in mobile-phone gaming, an industry whose products reach tens of millions of consumers-a new Wild West where the multimillionaires of tomorrow are still to be crowned. Mr. Mamujee says Zynga Inc., with its roughly 230 million monthly players and an initial public offering valuation that could reach $20 billion, has "won" the gaming race on Facebook Inc. But no one has conquered mobile, or figured out how to make as much money from it as Zynga has from its social-media games, he says. It's the challenge of becoming as successful as Zynga that drives Mr. Mamujee, he says, with the possibility of becoming wealthy an afterthought. ... http://online.wsj.com/article/SB10001424052970204323904577038462736751448.html
