#370 July 15, 2014 – China’s Computer is Fastest

This week’s headline story: China’s Computer is Fastest


China continues to lead the benchmark list of the 500 most powerful computers. Last week, the country’s Tianhe-2 supercomputer was cited as the world’s No. 1 system, capable of speeds of up to 33.86 petaflops. Powerful supercomputers like the Tianhe-2 enable higher resolutions for modeling and simulations, supporting more complex science and improving the possibility of researchers making breakthrough discoveries. Because of the research power supercomputers can provide a country, global competition in supercomputing has really ramped up in recent years. Still, the U.S. needn’t become overly concerned over China’s recent victory. While China may claim the fastest supercomputer, 90% of the top 500 supercomputers are made by U.S. vendors.

  • Forget the Shortest Route Across a City; New Algorithm Finds the Most Beautiful [TechnologyReview]

    The “shortest path” algorithm has been a favorite puzzle for computer science student for decades, and has valuable application in navigation systems. Google Maps, Bing Maps, Yahoo Maps and Mapquest are all very efficient at suggesting the shortest route for drivers. Some can even take into account current traffic congestion. But can any of these suggest the most beautiful route? Thanks to the work of Daniele Quercia at Yahoo Labs in Barcelona, Spain, this may become a popular new navigation feature. Daniele and his team have worked out how to measure the “beauty” of specific locations within cities and then designed an algorithm that automatically chooses a route between two locations in a way that maximizes the beauty along it. “The goal of this work is to automatically suggest routes that are not only short but also emotionally pleasant,” they say.

Security firm Avast Software bought 20 used Android smartphones, and was able to recover tens of thousands of personal files.
