Machine learning system can ID cities via pics

What makes Paris look like Paris? Hint: it ain't the Eiffel Tower.

It is instead the details woven into the urban fabric that form a pattern, according to a machine learning system that's part of a U.S.-French visual data mining project. Yes, computers are learning to ID your city just by looking at random photos.

Researchers at Carnegie Mellon University and INRIA/Ecole Normale Superieure in Paris had the system look at 40,000 Google Street View images of Paris, London, New York, and Barcelona, as well as eight other cities to find frequent and unique elements. … Read more

Curiosity rover gets chatty, clever on Twitter

Coming off the tremendous success of completing the "seven minutes of terror," the Mars Curiosity rover will now spend the next several weeks getting settled before embarking on its data-collecting two-year mission. So what does a solitary rover in a Mars crater do during its downtime? Chat it up on Twitter with its peeps back home, of course.

Earlier today, the official Sesame Street Twitter account sent a shout-out to the rover on Twitter, amusingly suggesting the children's entertainment company hoped to see its famous fictional Martian Yip Yips characters emerge on camera during the latest ground pictures from Mars.

Curiosity rover quickly tweeted back: "Science is cool. Yip-yip-yip-yip... Uh-huh. Uh-huh. #STEM #MSL" (Even BoingBoing served up a satirical screenshot wonderfully Photoshopped of what a Yip Yip on Mars would look like; see our own vision at right.) … Read more

When Google Street View and ASCII art collide

Long before 1080p video and high-resolution imagery, a special graphic design style known as ASCII art enabled amateur artists to create unique images on computers through specifically formatted text.

The glory days of text art invading e-mails and bulletin boards are mostly gone. But you can at least take a stroll down memory lane with a Web site that automatically converts Google Maps' Street View into a world of colorful ASCII art. … Read more

Google Street View pays visit to U.K. prime minister

Downing Street, the office and home of the British Prime Minister, has cleared the way for Google to map the famous road at street level. Users of Google Maps can now see the powerhouse of British politics on Street View.

With the Olympics in full swing and as an already packed London continues to swell, the Downing Street gates will remain tightly shut, barring anyone from entering the historic roadway. But anyone with a mobile phone, laptop, tablet or otherwise can check out David Cameron's front door. You don't even need a security pass; you can virtually just … Read more

Why Facebook's CEO ought to tell Wall Street to Zuck off

I'm sure Mark Zuckerberg won't lose any sleep about Wall Street's ongoing hissy fit about Facebook -- nor should he. More about that in a moment.

Following the disappointment over the company's second-quarter earnings, Facebook shares fell another 11.7 percent Friday, despite the market-lifting euphoria over the European Central Bank chief's plans to bolster the Euro.

An extreme sell-off, for sure, but not surprising for a stock that's tumbled almost 38 percent since its star-crossed debut on the NASDAQ in May.

Given how this outsize company has infiltrated popular culture, Facebook's fall … Read more

Google oops: Did not delete Street View data as promised

Google, right hand meet left hand?

The company was supposed to scrub all the personal user data its Street View vehicles in Britain and elsewhere had collected in 2010. Somehow, that did not happen.

Google disclosed the information on Friday to the U.K's. Information Commissioner's Office. As part of an agreement signed in November 2010, Google was supposed to have deleted the data by December 2010.

"Google has recently confirmed that it still has in its possession a small portion of...data collected by our Street View vehicles in the UK," Peter Fleischer, Google's … Read more

Twitter appeals ruling in Occupy Wall Street lawsuit

Twitter has decided to appeal a recent ruling in the legal battle between the social network and New York State over the tweet records of an Occupy Wall Street protester. According to All Things D, Twitter announced today that it's not giving up protecting the rights of its users.

Google Maps visits Antarctica's snowy landscape

Antarctica is long known to be an inhospitable place of constant cold and wind and completely void of plant life. It is also supposed to be beautiful -- filled with snowy vistas, blue-tinted glaciers, and penguins.

Google announced today that with the introduction of its new Google Maps feature people don't need to gear up, survive the elements, and make the long journey to explore this corner of the world. They can simply fire up their computers and take a tour with Antarctic Street View. … Read more
