On the heels of its agreement to buy Tumblr, Yahoo on Tuesday relaunched photo service Flickr. “There are no more bits of text or blue links, but rather a grid layout of huge pictures in full resolution,” TechCrunch notes. Also, “Stemming from the updated iOS app recently … the company is also announcing a brand new Android experience, catching the Google version of the Flickr app up to the iOS version.”

Adding to suspicions that Apple is losing its luster, new data shows that customers are not as happy with the company’s phones as they were a year ago. “According to an American Customer Satisfaction Index report issued today, Apple received a score of 81 (on a scale of 100) in terms of customer satisfaction,” CNet reports. “But the company dropped 2 percent from its 2012 position, and the iPhone lags the customer satisfaction rating of 86 for Apple's desktop, laptop, and tablet business.”

After a short pause, Chinese hackers have reportedly resumed their attacks on various U.S. targets, including some of the nation’s top consumer brands. “Three months after hackers working for a cyber unit of China’s People’s Liberation Army went silent … they appear to have resumed their attacks,” The New York Times reports. 

In honor of its eighth birthday, YouTube has released some viewership data worth celebrating. “Most staggeringly, over 100 hours of video are now uploaded to YouTube each and every minute,” The Verge reports. “One year ago on this day, that figure stood at 72 hours per minute (it was 48 hours in 2011).” More broadly, more than 1 billion users now visit Google’s video hub every month. 

Don’t call it advertising, but Pinterest just debuted a new type of pin, which is seen as a first step in integrating images with associated brands, making it easier for users to click through links and purchase items. “The move could be the start of a change in consumer perception of the site from a place for wishful thinking to a site where one can purchase those wishes,” GigaOm reports. Launch partners include eBay, Etsy, Home Depot, Neiman Marcus, Overstock, REI, Sephora, and Sony. 

In what has become a necessary step for any successful operating system, Google Glass is starting to attract its own app ecosystem. Google’s ambitious wearable computer will soon have seven new apps, “including breaking news alerts from CNN, fashion features from Elle, Twitter, Tumblr and Facebook posts and reminder notes from Evernote,” The New York Times’ Bits blog reports. Google, in case you were wondering, calls the apps “Glassware.” 

Speaking of Groupon, the deal site says it’s unlikely to name a permanent new CEO until next year. “The company, which stumbled badly after going public in 2011, has been looking for someone to fill the top job since it ousted Andrew Mason in February following a string of missteps and disappointing results,” The Wall Street Journal reports. “The long search means it will fall to temporary CEOs Ted Leonsis and Eric Lefkofsky to put the company on more stable footing.” 

What’s Andrew Mason been up to since being booted from the top spot at Groupon? Well, he just joined Y Combinator as a part-time partner, TechCrunch reports. Also, Mason explains in his own blog post, he’s moving to San Francisco, releasing an album of “motivational business music” (a joke, we assume), and starting a new company. “If there’s a silver lining to leaving Groupon, it’s the opportunity to start something new,” he writes. “I’ve accumulated a backlog of ideas over the last several years, my favorite of which I’ll be turning into a new company this fall.” 

Yahoo is reportedly considering partnering with, investing in, or buying Tumblr. “Sources said the talks were serious, but any kind of deal -- of course -- could come to naught,” AllThingsD reports. Any such deal is part of a broader effort to make Yahoo “cool again,” as Yahoo CFO Ken Goldman put it earlier this week. 

Google and NASA are creating a laboratory to study artificial intelligence. Their focus, as The New York Times’ Bits blog reports, will be “computers that use the unusual properties of quantum physics.” Sometime later this year, the partners’ quantum computer, which performs complex calculations thousands of times faster than existing supercomputers, is expected to be up and running.
