A Chinese supercomputer known as Tianhe-2 was today named the world’s fastest machine, nearly doubling the previous speed record with its performance of 33.86 petaflops. Tianhe-2’s ascendance was revealed in advance and was made official today with the release of the new Top 500 supercomputer list . Tianhe-2 was developed at China’s National University of Defense Technology and will be deployed in the country’s National Supercomputing Center before the end of this year. “The surprise appearance of Tianhe-2, two years ahead of the expected deployment, marks China’s first return to the No. 1 position since November 2010, when Tianhe-1A was the top system,” the Top 500 announcement states. “Tianhe-2 has 16,000 nodes, each with two Intel Xeon Ivy Bridge processors and three Xeon Phi processors for a combined total of 3,120,000 computing cores.” The combined performance of the 500 systems on the list is 223 petaflops, up from 162 petaflops in the previous list released six months ago. A petaflop represents one quadrillion floating point operations per second, or a million billion. Read 3 remaining paragraphs | Comments

The ten fastest supercomputers on the planet, in pictures
On the Guardian right now NSA whistleblower Edward Snowden is answering live questions from the world at large. 1) First, the US Government, just as they did with other whistleblowers, immediately and predictably destroyed any possibility of a fair trial at home, openly declaring me guilty of treason and that the disclosure of secret, criminal, and even unconstitutional acts is an unforgivable crime. That’s not justice, and it would be foolish to volunteer yourself to it if you can do more good outside of prison than in it. Second, let’s be clear: I did not reveal any US operations against legitimate military targets. I pointed out where the NSA has hacked civilian infrastructure such as universities, hospitals, and private businesses because it is dangerous. These nakedly, aggressively criminal acts are wrong no matter the target. Not only that, when NSA makes a technical mistake during an exploitation operation, critical systems crash. Congress hasn’t declared war on the countries – the majority of them are our allies – but without asking for public permission, NSA is running network operations against them that affect millions of innocent people. And for what? So we can have secret access to a computer in a country we’re not even fighting? So we can potentially reveal a potential terrorist with the potential to kill fewer Americans than our own Police? No, the public needs to know the kinds of things a government does in its name, or the “consent of the governed” is meaningless. The whistleblower behind the biggest intelligence leak in NSA history will be live online at 11am ET/4pm BST to answer your questions about the NSA surveillance revelations 
That’s the claim from TechCrunch, which says that Facebook’s special press event on June 20 will be focused in part on video and Instagram. [Read more] 
bill_mcgonigle writes with this news from from CNET: “Rep. Jerrold Nadler (D NY) disclosed that NSA analysts eavesdrop on Americans’ domestic telephone calls without court orders during a House Judiciary hearing. After clearing with FBI director Robert Mueller that the information was not classified, Nadler revealed that during a closed-door briefing to Congress, the Legislature was informed that the spying organization had implemented and uses this capability. This appears to confirm Edward Snowden’s claim that he could, in his position at the NSA, ‘wiretap anyone from you or your accountant to a federal judge to even the president.’ Declan McCullagh writes, ‘Because the same legal standards that apply to phone calls also apply to e-mail messages, text messages, and instant messages, Nadler’s disclosure indicates the NSA analysts could also access the contents of Internet communications without going before a court and seeking approval.’ The executive branch has defended its general warrants, claiming that ‘the president had the constitutional authority, no matter what the law actually says, to order domestic spying without [constitutional] warrants,’ while Kurt Opsahl, senior staff attorney at EFF claims such government activity ‘epitomizes the problem of secret laws.'” Note that “listening in” versus “collecting metadata” is a distinction that defenders of government phone spying have been emphasizing. Tracking whom you called and when, goes the story, doesn’t impinge on expectations of privacy. Speaking of the metadata collection, though, reader Bruce66423 writes “According to the Washington Post, the Bush administration took ‘bulk metadata’ from the phone companies under voluntary agreements for more than four years after 9/11 until a court agreed they could have it compulsorily.” Related: First time accepted submitter fsagx writes that Brewster Kahle of the Internet Archive has calculated the cost to store every phone call made in the U.S. over the course of a year: “It’s surprisingly inexpensive. It puts the recent NSA stories (and reports from the Boston bombings about the FBI’s ability to listen to past phone conversions) into perspective.” Read more of this story at Slashdot.
