Microsoft started internal demos of its dual-screen Surface hardware, codenamed Centaurus, including an “all-hands” event for its device team, said sources. The company allowed employees to get up close to the prototype hardware, and also showed a sizzle reel. Centaurus, in development for about two years, is intended to be the showpiece of the company’s upcoming assortment of dual-screen tablet/laptop hybrids. Sources also said that Centaurus is more similar to the Courier tablet than the prior Andromeda project. Read more

Facebook-owned photo- and video-sharing app Instagram announced yesterday that it plans a change to its advertising strategy that involves more sponsored ads from social influencers. Instagram will offer brands the ability to promote creators’ branded content in users’ feeds, regardless of whether or not those users follow the influencers creating the content.

U.S. tech giants are expected to become targets of in-depth antitrust investigations to determine if any companies have become too large and may be stifling competition.

Most of the time, the bots played a capture-the-flag video game better than human game testers who are professional. DeepMind researcher Max Jaderberg said that the work, first described in the company blog last year, is moving towards “developing the fundamental algorithms” that could in the future lead to a “more human intelligence.” Not every lab, however, can afford the compute power required.

Determining the impact of screen time isn’t easy. It’s almost impossible to put together a “control group” of people living non-digital lives, and there are no baselines for such factors as “average daily Facebook usage.” Stanford University professor of communication Byron Reeves, in a paper in Human-Computer Interaction, suggested a new approach that eschews the term “screen time” as hopelessly ambiguous. Instead, he argued, scientists should analyze what people are watching — but this data doesn’t exist. Read more
