Scientists May Have Decoded One of the Secrets to Superconductors | Science | WIRED - 0 views

  • “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.

Massachusetts Man Charged Criminally For Videotaping Cop... Despite Earlier Lawsuit Rej... - 0 views

  • You may remember a high-profile, landmark ruling last year in Massachusetts, where charges against Simon Glik -- arrested for violating a state law that said it's "wiretapping" to record a police officer in public without his permission -- weren't just dropped, but the arrest was found to be both a First and Fourth Amendment violation. In the end, Boston was forced to pay Glik $170,000 for violating his civil rights. You would think that story would spread across Massachusetts pretty quickly and law enforcement officials and local district attorneys would recognize that filing similar charges would be a certified bad idea. Not so, apparently, in the town of Shrewsbury. Irving J. Espinosa-Rodrigue was apparently arrested and charged under the very same statute after having a passenger in his car videotape a traffic stop for speeding, and then posting the video on YouTube. Once again, the "issue" is that Massachusetts is a "two-party consent" state, whereby an audio recording can't be done without first notifying the person being recorded, or its deemed a "wiretap." This interpretation, especially when dealing with cops in public, is flat-out ridiculous and unconstitutional, as the Glik ruling showed.

How Covert Agents Infiltrate the Internet to Manipulate, Deceive, and Destroy Reputatio... - 0 views

  • “The Art of Deception: Training for Online Covert Operations.”
  • Among the core self-identified purposes of JTRIG are two tactics: (1) to inject all sorts of false material onto the internet in order to destroy the reputation of its targets; and (2) to use social sciences and other techniques to manipulate online discourse and activism to generate outcomes it considers desirable. To see how extremist these programs are, just consider the tactics they boast of using to achieve those ends: “false flag operations” (posting material to the internet and falsely attributing it to someone else), fake victim blog posts (pretending to be a victim of the individual whose reputation they want to destroy), and posting “negative information” on various forums. 
  • Critically, the “targets” for this deceit and reputation-destruction extend far beyond the customary roster of normal spycraft: hostile nations and their leaders, military agencies, and intelligence services. In fact, the discussion of many of these techniques occurs in the context of using them in lieu of “traditional law enforcement” against people suspected (but not charged or convicted) of ordinary crimes or, more broadly still, “hacktivism”, meaning those who use online protest activity for political ends. The title page of one of these documents reflects the agency’s own awareness that it is “pushing the boundaries” by using “cyber offensive” techniques against people who have nothing to do with terrorism or national security threats, and indeed, centrally involves law enforcement agents who investigate ordinary crimes:

  • it is not difficult to see how dangerous it is to have secret government agencies being able to target any individuals they want – who have never been charged with, let alone convicted of, any crimes – with these sorts of online, deception-based tactics of reputation destruction and disruption.
    • John Lemke
       
      Not only are you now guilty until proven innocent but, if you are guilty enough, we shall create a situation so that you are.
  • Government plans to monitor and influence internet communications, and covertly infiltrate online communities in order to sow dissension and disseminate false information, have long been the source of speculation. Harvard Law Professor Cass Sunstein, a close Obama adviser and the White House’s former head of the Office of Information and Regulatory Affairs, wrote a controversial paper in 2008 proposing that the US government employ teams of covert agents and pseudo-”independent” advocates to “cognitively infiltrate” online groups and websites, as well as other activist groups. Sunstein also proposed sending covert agents into “chat rooms, online social networks, or even real-space groups” which spread what he views as false and damaging “conspiracy theories” about the government. Ironically, the very same Sunstein was recently named by Obama to serve as a member of the NSA review panel created by the White House, one that – while disputing key NSA claims – proceeded to propose many cosmetic reforms to the agency’s powers (most of which were ignored by the President who appointed them).
    • John Lemke
       
      So one of the guys who advocates this and approves of it, gets to be on the NSA review committee?  Isn't that like Ted Kennedy on the Ethics Review Committee or the Warren Commission?
  • Whatever else is true, no government should be able to engage in these tactics: what justification is there for having government agencies target people – who have been charged with no crime – for reputation-destruction, infiltrate online political communities, and develop techniques for manipulating online discourse? But to allow those actions with no public knowledge or accountability is particularly unjustifiable.

Hackers charged with stealing Xbox, 'Call of Duty,' and US Army secrets worth over $100... - 0 views

  • Four hackers have been jointly charged with conspiracies to commit computer fraud, copyright infringement, wire fraud, mail fraud, identity theft, and theft of trade secrets. Individually, they have been charged with counts of aggravated identity theft, unauthorized computer access, copyright infringement, and wire fraud.
  • The defendants, aged between 18 and 28, are believed to have stolen more than $100 million in intellectual property and other proprietary data from the likes of Microsoft Corporation, Epic Games, Valve, and even the US Army. This includes pre-release versions of Gears of War 3 and Call of Duty: Modern Warfare 3, Apache helicopter simulation software developed for the US army, and information about the Xbox One console. Two of the suspects have pleaded guilty, one of which is 22-year old David Pokora. His plea represents what may be the first conviction of a foreign-based individual for hacking into US businesses to steal trade secret information.

Swedes may soon exchange postage stamps for SMS codes - 0 views

  •  
    that ritual is about to be replaced with a more high-tech one: people may soon be able to pay for their postage via text message, thereby eliminating the need for a stamp. The system works like this: Swedes will be able to send a text message to the postal service saying that they want postage for a letter. The postal service will then presumably charge an account on file, then respond with another text that contains a code. The letter-sender will then write the code on the envelope to show that postage had been paid.

Personal file-sharing is legal in Portugal, prosecutor says | Ars Technica - 0 views

  • Portugese prosecutors have declined to press charges against individuals accused of file sharing
  • “From a legal point of view, while taking into account that users are both uploaders and downloaders in these file-sharing networks, we see this conduct as lawful, even when it’s considered that the users continue to share once the download is finished.” The prosecutor adds that the right to education, culture, and freedom of expression on the Internet should not be restricted in cases where the copyright infringements are clearly non-commercial. In addition, the order notes that an IP-address is not a person.

FBI Arrested CEO of 'StealthGenie' for Selling Mobile Spyware Apps - 0 views

  • The Federal Bureau of Investigation (FBI) has arrested the CEO of a UK-based company for allegedly advertising and selling a spyware app to individuals who suspect their romantic partners of cheating on them.
  • The dodgy cell phone spyware application, dubbed as StealthGenie, monitors victims’ phone calls, text messages, videos, emails and other communications "without detection" when it is installed on a target's phone, according to the Department of Justice.
  • Once installed on the phone, it allows conversations to be monitored as they take place, enables the purchaser to call the phone and activate it at any time to monitor all surrounding conversations within a 15-foot radius, and collects the user’s incoming and outgoing email and SMS messages, incoming voicemail, address book, calendar, photographs, and videos. All of these functions are enabled without the knowledge of the user of the phone.

The White House Big Data Report: The Good, The Bad, and The Missing | Electronic Fronti... - 0 views

  • the report recognized that email privacy is critical
  • one issue was left conspicuously unaddressed in the report. The Securities and Exchange Commission, the civil agency in charge of protecting investors and ensuring orderly markets, has been advocating for a special exception to the warrant requirement. No agency can or should have a get-out-of-jail-free card for bypassing the Fourth Amendment.

  • an example of this in Boston, which had a pilot program to allow residents to report potholes through a mobile app but soon recognized that the program was inherently flawed because “wealthy people were far more likely to own smart phones and to use the Street Bump app. Where they drove, potholes were found; where they didn’t travel, potholes went unnoted.”
  • The authors of the report agree, recommending that the Privacy Act be extended to all people, not just US persons.
  • metadata (the details associated with your communications, content, or actions, like who you called, or what a file you uploaded file is named, or where you were when you visited a particular website) can expose just as much information about you as the “regular” data it is associated with, so it deserves the same sort of privacy protections as “regular” data.
    • John Lemke
       
      What is Metadate... then discuss
  • The report merely recommended that the government look into the issue.
    • John Lemke
       
      Did the report give a strong enough recommendation? "looking into" and doing are much different
  • several other government reports have taken a much stronger stance and explicitly stated that metadata deserves the same level of privacy protections as “regular” data.
  • We think the report should have followed the lead of the PCAST report and acknowledged that the distinction between data and metadata is an artificial one, and recommended the appropriate reforms.
    • John Lemke
       
      I very strongly agree.  The report failed in this area.
  • the White House suggested advancing the Consumer Privacy Bill of Rights, which includes the idea that “consumers have a right to exercise control over what personal data companies collect from them and how they use it,” as well as “a right to access and correct personal data.”
  • Consumers have a right to know when their data is exposed, whether through corporate misconduct, malicious hackers, or under other circumstances. Recognizing this important consumer safeguard, the report recommends that Congress “should pass legislation that provides a single national data breach standard along the lines of the Administration's May 2011 Cybersecurity legislative proposal.”
  • While at first blush this may seem like a powerful consumer protection, we don’t think that proposal is as strong as existing California law. The proposed federal data breach notification scheme would preempt state notification laws, removing the strong California standard and replacing it with a weaker standard.
    • John Lemke
       
      In other words, it failed at what can be done and it would actually lower standards when compared to what California has in place currently.

      WTF? how did he get in this group?
  • two big concerns
  • First, whistleblowers are simply not comparable to an Army officer who massacres his fellow soldiers
  • Secondly, the real big-data issue at play here is overclassification of enormous quantities of data.
  • Over 1.4 million people hold top-secret security clearances. In 2012, the government classified 95 million documents. And by some estimates, the government controls more classified information than there is in the entire Library of Congress.
    • John Lemke
       
      Don't leave this stat out.  More classified documents than LOC documents.  WTF? A "democracy" with more secret documents than public?
  • The report argues that in today’s connected world it’s impossible for consumers to keep up with all the data streams they generate (intentionally or not), so the existing “notice and consent” framework (in which companies must notify and get a user’s consent before collecting data) is obsolete. Instead, they suggest that more attention should be paid to how data is used, rather than how it is collected.
    • John Lemke
       
      This is the most troubling part perhaps,  isn't the collection without consent where the breech of privacy begins?
    • John Lemke
       
      "notice and consent"
  • An unfortunate premise of this argument is that automatic collection of data is a given
  • While we agree that putting more emphasis on responsible use of big data is important, doing so should not completely replace the notice and consent framework.
  • Despite being a fairly thorough analysis of the privacy implications of big data, there is one topic that it glaringly omits: the NSA’s use of big data to spy on innocent Americans.
    • John Lemke
       
      If we ignore it, it will go away?  Did they not just mostly ignore it and accept it as a given for corporations and completely ignore it regarding the government? Pretty gangster move isn't it?
  • Even though the review that led to this report was announced during President Obama’s speech on NSA reform, and even though respondents to the White House’s Big Data Survey “were most wary of how intelligence and law enforcement agencies are collecting and using data about them,” the report itself is surprisingly silent on the issue.2 This is especially confusing given how much the report talks about the need for more transparency in the private sector when it comes to big data. Given that this same logic could well be applied to intelligence big data programs, we don’t understand why the report did not address this vital issue.

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.”
  • ...4 more annotations...
  • 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.
    • John Lemke
       
      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.

Cops Seize Car When Told To Get A Warrant, Tell Owner That's What He Gets For 'Exercisi... - 0 views

  • Officer Hatch spent most of his time trying to talk Zullo into allowing him to search the vehicle without a warrant. Hatch seemed to be convinced that Zullo was involved with the heroin traffickers he was searching for. Hatch tried everything, including lying.
  • As the officers and Zullo waited for the tow truck, they continued to try to get his permission for a search. Zullo held firm, so the cops ditched him miles from home in 20-degree weather. Mr. Zullo asked Hatch if he could retrieve his money and cell phone from his car, because he did not know how he would get home without either item. Hatch refused, saying that getting home was “not my problem,” and warned Mr. Zullo that if he attempted to retrieve those items from the car he would be arrested. When Mr. Zullo walked towards his car, Hatch placed his hands on Mr. Zullo to restrain him from reaching the car. After the tow truck arrived and took Mr. Zullo’s car, Hatch and the second state trooper left the scene, leaving Mr. Zullo stranded on the side of Route 7.
