2013 leak gaming terrorist propaganda training tool ars

  • But those leaked documents also include an in-depth report on the potential for games to be used as recruitment, training, and propaganda tools by extremist organizations.
  • Even if, as the report says, "the line between the ‘virtual’ world and the ‘real’ world is blurring, and to some users may be non-existent," most of the game-related terrorist training and planning scenarios laid out here seem a lot less likely than plain old non-game-related options. In any case, the leak of this report and the scenarios it outlines show that the security apparatus is interested in online games as more than just a place to spy on potential enemy communications.

  • “In the same way that a laser is a hell of a lot more powerful than a light bulb, room-temperature superconductivity would completely change how you transport electricity and enable new ways of using electricity,” said Louis Taillefer, a professor of physics at the University of Sherbrooke in Quebec.
  • ripples of electrons inside the superconductors that are called charge density waves. The fine-grained structure of the waves, reported in two new papers by independent groups of researchers, suggests that they may be driven by the same force as superconductivity. Davis and his colleagues directly visualized the waves in a study posted online in April, corroborating indirect evidence reported in February by a team led by Riccardo Comin, a postdoctoral fellow at the University of Toronto.
  • Taken together, the various findings are at last starting to build a comprehensive picture of the physics behind high-temperature superconductivity. “This is the first time I feel like we’re making real progress,” said Andrea Damascelli, a professor of physics at the University of British Columbia who led two recent studies on charge density waves. “A lot of different observations which have been made over decades did not make sense with each other, and now they do.”

  • The community remained divided until 2012, when two groups using a technique called resonant X-ray scattering managed to detect charge density waves deep inside cuprates, cementing the importance of the waves. As the groups published their findings in Science and Nature Physics, two new collaborations formed, one led by Damascelli and the other by Ali Yazdani of Princeton University, with plans to characterize the waves even more thoroughly. Finishing in a dead heat, the rival groups’ independent studies appeared together in Science in January 2014. They confirmed that charge density waves are a ubiquitous phenomenon in cuprates and that they strenuously oppose superconductivity, prevailing as the temperature rises.
  • y applying Sachdev’s algorithm to a new round of data, Davis and his group mapped out the structure of the charge density waves, showing that the d-wave distribution of electrons was, indeed, their source.
  • The waves’ structure is particularly suggestive, researchers say, because superconducting pairs of electrons also have a d-wave configuration. It’s as if both arrangements of electrons were cast from the same mold. “Until a few months ago my thought was, OK, you have charge density waves, who cares? What’s the relevance to the high-temperature superconductivity?” Damascelli said. “This tells me these phenomena feed off the same interaction.”
  • In short, antiferromagnetism could generate the d-wave patterns of both superconductivity and its rival, charge density waves.

Lights out: The dark future of electric power - opinion - 12 May 2014 - New Scientist - 0 views

  • We tend to think of such events as occasional, inconvenient blips. But in fact they are becoming increasingly common, and will only get more frequent and severe. This is because our electricity systems are more fragile than is commonly supposed, and are getting frailer. Unless we act, blackouts will become a regular, extremely disruptive part of everyday life.
  • The vulnerability of such systems is demonstrated by the Italian blackout of 2003. The event began when a falling tree broke a power line in Switzerland; when a second tree took out another Swiss power line, connectors towards Italy tripped and several Italian power plants failed as a result. Virtually the whole country was left without power. It says something when a nation can be brought to a halt by two trees falling outside its borders.
  • We predict that blackouts will occur with greater frequency and greater severity due to trends in both electricity supply and demand. Supply will become increasingly precarious because of the depletion of fossil fuels, neglected infrastructure and the shift toward less reliable renewable energy. Demand, meanwhile, will grow because of rising populations and affluence.

  • Between 1940 and 2001, average US household electricity use rose 1300 per cent, driven largely by growing demand for air conditioning. And such demand is forecast to grow by 22 per cent in the next two decades.

    While not a green energy story, it is relevant.  The reality is that our demand for power is growing quicker than the volume of power we can produce.

New Zealand Launched Mass Surveillance Project While Publicly Denying It - The Intercept - 0 views

  • Documents provided by NSA whistleblower Edward Snowden show that the government worked in secret to exploit a new internet surveillance law enacted in the wake of revelations of illegal domestic spying to initiate a new metadata collection program that appeared designed to collect information about the communications of New Zealanders.
  • Those actions are in direct conflict with the assurances given to the public by Prime Minister John Key (pictured above), who said the law was merely designed to fix “an ambiguous legal framework” by expressly allowing the agency to do what it had done for years, that it “isn’t and will never be wholesale spying on New Zealanders,” and the law “isn’t a revolution in the way New Zealand conducts its intelligence operations.”
  • Snowden explained that “at the NSA, I routinely came across the communications of New Zealanders in my work with a mass surveillance tool we share with GCSB, called ‘X KEYSCORE.”" He further detailed that “the GCSB provides mass surveillance data into XKEYSCORE. They also provide access to the communications of millions of New Zealanders to the NSA at facilities such as the GCSB facility in Waihopai, and the Prime Minister is personally aware of this fact.”

  • Top secret documents provided by the whistleblower demonstrate that the GCSB, with ongoing NSA cooperation, implemented Phase I of the mass surveillance program code-named “Speargun” at some point in 2012
  • Over the weekend, in anticipation of this report, Key admitted for the first time that the GCSB did plan a program of mass surveillance aimed at his own citizens, but claimed that he ultimately rejected the program before implementation. Yesterday, after The Intercept sought comment from the NSA, the Prime Minister told reporters in Auckland that this reporting was referring merely to “a proposed widespread cyber protection programme that never got off the ground.” He vowed to declassify documents confirming his decision.
  • That legislation arose after it was revealed in 2012 that the GCSB illegally surveilled the communications of Megaupload founder Kim Dotcom, a legal resident of New Zealand. New Zealand law at the time forbade the GCSB from using its surveillance apparatus against citizens or legal residents. That illegal GCSB surveillance of Dotcom was followed by a massive military-style police raid by New Zealand authorities on his home in connection with Dotcom’s criminal prosecution in the United States for copyright violations. A subsequent government investigation found that the GCSB not only illegally spied on Dotcom but also dozens of other citizens and legal residents. The deputy director of GCSB resigned. The government’s response to these revelations was to refuse to prosecute those who ordered the illegal spying and, instead, to propose a new law that would allow domestic electronic surveillance.

      The Dotcom raid was ruled illegal.  Yet the Dotcom spying was exactly the type of activity of this plan.
  • n high-level discussions between the Key government and the NSA, the new law was clearly viewed as the crucial means to empower the GCSB to engage in metadata surveillance. On more than one occasion, the NSA noted internally that Project Speargun, in the process of being implemented, could not and would not be completed until the new law was enacted.
