China Is Becoming a Supercomputing Powerhouse
U.S. tally of world’s most powerful supercomputers is at its lowest since Top500 list began
WSJ. Nov. 16, 2015
For the past two years, the country has been home to the world’s most powerful supercomputer, the National University of Defense Technology’s Tianhe-2 machine.
… Over the past decade, companies such as Alphabet Inc. ’s Google, Amazon.com Inc. and Facebook Inc. have spent billions building massive data centers that operate as supercomputers for the Internet. These systems, however, aren’t optimized for the type of calculations that the Top500 list’s benchmarks test for.
… The Top500 results are important because they serve as a shorthand way of viewing international competitiveness in computer simulations. Originally used for scientific modeling in physics and chemistry, these systems are increasingly used to simulate consumer products—everything from automobiles to diapers.
… Tianhe-2, which has been ranked the world’s most powerful supercomputer since June 2013, is capable of performing 33.86 quadrillion calculations a second. The system ranked second on the list, Oak Ridge National Laboratory’s Titan, can perform 17.59 quadrillion calculations a second.

Unified School District’s newly implemented courses.
they pair computer science professionals with classroom teachers. This enables the teachers to get the professional development necessary to oversee these sometimes-complex computer science courses.
high school students are applying computer science concepts like variables and loops to build classic games using Berkeley’s drag-and-drop Snap programming language
The future of cryptocurrencies: Bitcoin and beyond
The digital currency has caused any number of headaches for law enforcement. Now entrepreneurs and academics are scrambling to build a better version.
30 September 2015
Today, there are some 14.6 million Bitcoin units in circulation. Called bitcoins with a lowercase ‘b’, they have a collective market value of around US$3.4 billion. Some of this growth is attributable to criminals taking advantage of the anonymity for drug trafficking and worse. But the system is also drawing interest from financial institutions such as JP Morgan Chase, which think it could streamline their internal payment processing and cut international transaction costs. It has inspired the creation of some 700 other cryptocurrencies. And on 15 September, Bitcoin officially came of age in academia with the launch of Ledger, the first journal dedicated to cryptocurrency research.
the community of developers and academics behind it is unique. “It’s a remarkable body of knowledge, and we’re going to be teaching this in computer science classes in 20 years, I’m certain of that.”
