The American Wikileaks Hacker | Rolling Stone Culture - 0 views

  •  
    On July 29th, returning from a trip to Europe, Jacob Appelbaum, a lanky, unassuming 27-year-old wearing a black T-shirt with the slogan "Be the trouble you want to see in the world," was detained at customs by a posse of federal agents. In an interrogation room at Newark Liberty airport, he was grilled about his role in Wikileaks, the whistle-blower group that has exposed the government's most closely guarded intelligence reports about the war in Afghanistan. The agents photocopied his receipts, seized three of his cellphones - he owns more than a dozen - and confiscated his computer. They informed him that he was under government surveillance. They questioned him about the trove of 91,000 classified military documents that Wikileaks had released the week before, a leak that Vietnam-era activist Daniel Ellsberg called "the largest unauthorized disclosure since the Pentagon Papers." They demanded to know where Julian Assange, the founder of Wikileaks, was hiding. They pressed him on his opinions about the wars in Afghanistan and Iraq. Appelbaum refused to answer. Finally, after three hours, he was released. Sex, Drugs, and the Biggest Cybercrime of All Time Appelbaum is the only known American member of Wikileaks and the leading evangelist for the software program that helped make the leak possible. In a sense, he's a bizarro version of Mark Zuckerberg: If Facebook's ambition is to "make the world more open and connected," Appelbaum has dedicated his life to fighting for anonymity and privacy. An anarchist street kid raised by a heroin- addict father, he dropped out of high school, taught himself the intricacies of code and developed a healthy paranoia along the way. "I don't want to live in a world where everyone is watched all the time," he says. "I want to be left alone as much as possible. I don't want a data trail to tell a story that isn't true." We have transferred our most intimate and personal information - our bank accounts, e-mails, photographs, ph

'World Wide Mind' - Total Connectedness, and Its Consequences - NYTimes.com - 0 views

  •  
    Imagine, Michael Chorost proposes, that four police officers on a drug raid are connected mentally in a way that allows them to sense what their colleagues are seeing and feeling. Tony Vittorio, the captain, is in the center room of the three-room drug den. He can sense that his partner Wilson, in the room on his left, is not feeling danger or arousal and thus has encountered no one. But suddenly Vittorio feels a distant thump on his chest. Sarsen, in the room on the right, has been hit with something, possibly a bullet fired from a gun with a silencer. Vittorio glimpses a flickering image of a metallic barrel pointed at Sarsen, who is projecting overwhelming shock and alarm. By deducing how far Sarsen might have gone into the room and where the gunman is likely to be standing, Vittorio fires shots into the wall that will, at the very least, distract the gunman and allow Sarsen to shoot back. Sarsen is saved; the gunman is dead. That scene, from his new book, "World Wide Mind," is an example of what Mr. Chorost sees as "the coming integration of humanity, machines, and the Internet." The prediction is conceptually feasible, he tells us, something that technology does not yet permit but that breaks no known physical laws.

25% of US car accidents due to using gadgets | KurzweilAI - 0 views

  •  
    Driving distractions such as cell phones and other electronic devices cause as much as 25% of all U.S. car accidents, researchers at the Governors Highway Safety Association have found, WinBETA notes. A major finding was that being distracted was the cause of 15 to 25% of all accidents, ranging from minor property damage to death. Their findings suggest that distracted driving accidents be reported in accident reports to assist in evaluating distracted driving laws and programs. They propose creating low-cost roadway measures that alert motorists when they are drifting out of their driving lane. They also propose that all cell phones be banned on the road, even hands-free versions. In another report by The New York Times, police in Syracuse and Hartford have handed out nearly 20,000 tickets for illegal use of a phone while driving - either for texting or use of a handheld phone. According to the federal government, these efforts have had the desired effect: distracted driving has fallen sharply. Their research shows that drivers talking on a phone are four times as likely to get into a crash as those not on a phone, and that the risks for motorists who text are at least twice as high. In Syracuse, handheld cellphone use and texting have each fallen by one-third. In Hartford, handheld cellphone use by drivers fell 57 percent while texting fell by 75 percent, the Times reports.

Stressed-DNA repair protein identified | KurzweilAI - 0 views

  •  
    Vera Gorbunova and Andrei Seluanov of the University of Rochester have found that human cells undergoing oxidative stress caused by environmental chemicals or routine cellular processes produce a protein (SIRT6) that stimulates cells to repair DNA double-strand breaks, thought to be associated with premature aging and cancer. The team first measured levels of SIRT6 in stressed cells, then treated a second group of stressed cells with a drug that deactivates the protein. DNA repair in the second group stopped, confirming SIRT6′s role.  The team also found that SIRT6 acts in concert with another protein, called PARP1, to make the repairs. Furthermore, the team found that increased levels of SIRT6 lead to faster DNA repair. They suspect that the protein acts as a "master regulator," coordinating stress and DNA repair activities. Ref.: Zhiyong Mao, Christopher Hine, Xiao Tian, Michael Van Meter, Matthew Au, Amita Vaidya, Andrei Seluanov, and Vera Gorbunova. SIRT6 Promotes DNA Repair Under Stress by Activating PARP1. Science 17 June 2011: 1443-1446. [DOI:10.1126/science.1202723]

Rationally Speaking: The very foundations of science - 0 views

  • The first way to think about probability is as a measure of the frequency of an event: if I say that the probability of a coin to land heads up is 50% I may mean that, if I flip the coin say 100 times, on average I will get heads 50 times. This is not going to get us out of Hume’s problem, because probabilities interpreted as frequencies of events are, again, a form of induction
  • Secondly, we can think of probabilities as reflecting subjective judgment. If I say that it is probable that the coin will land heads up, I might simply be trying to express my feeling that this will be the case. You might have a different feeling, and respond that you don’t think it's probable that the coin will lend heads up. This is certainly not a viable solution to the problem of induction, because subjective probabilities are, well, subjective, and hence reflect opinions, not degrees of truth.
  • Lastly, one can adopt what Okasha calls the logical interpretation of probabilities, according to which there is a probability X that an event will occur means that we have objective reasons to believe (or not) that X will occur (for instance, because we understand the physics of the solar system, the mechanics of cars, or the physics of coin flipping). This doesn’t mean that we will always be correct, but it does offer a promising way out of Hume’s dilemma, since it seems to ground our judgments on a more solid foundation. Indeed, this is the option adopted by many philosophers, and would be the one probably preferred by scientists, if they ever gave this sort of thing a moment’s thought.

5 Things That Internet Porn Reveals About Our Brains | Sex & the Brain | DISCOVER Magazine - 0 views

  •  
    With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

Make plastic objects appear before your eyes - 0 views

  •  
    Everyone has experienced a broken knob or a broken piece off of an appliance. You also know that while trying to get a new one you might have a long waiting period. Well there might be a prototype that is here to solve that problem. The Thing-O-Matic claims to manifest any three-dimensional plastic object in just minutes. The machine was shown first at a Las Vegas trade fair and is meant to make manufacturing more common for the average person.\n\n3,000 have already been sold at $790 a device. This model only makes plastic objects but the manufacturers say that in the future models could make metal and plastic models to make super cool gadgets. The machines make objects that are six by six by seven inches. The machine is not capable of making images but it does make boxes, tubes and get this- even action figures!

The Role of Intimacy in the Evolution of Technology - 0 views

  •  
    by Alessandro Tomasi In this article, Georges Bataille's notion of intimacy will be re-interpreted to show that it has a role to play in the evolution of technology. The specifically human form of intimacy can be experienced through the successful adoption of technological devices that have the qualities necessary to fit in and work out in our life context. If they manage to become part of our life, then we experience them as projections of our psychophysical personality, and, as such, they escape our positing, objectifying consciousness. Intimacy can be seen as the organizing principle that shapes the evolution of technology towards an ideal end that promises at least an approximation to the absolute intimacy that is unique to the gods.

FORA.tv - Steven Johnson and Kevin Kelly at the NYPL - 0 views

  •  
    In a world of rapidly accelerating change, from iPads to eBooks to genetic mapping to MagLev trains, we can't help but wonder if technology is our servant or our master, and whether it is taking us in a healthy direction as a society.* What forces drive the steady march of innovation?* How can we build environments in our schools, our businesses, and in our private lives that encourage the creation of new ideas--ideas that build on the new technology platforms in socially responsible ways?Kevin Kelly and Steven Johnson look at where technology is taking us. One of the co-founders of Wired Magazine, Kelly's new book, What Technology Wants, makes the argument that technology as a whole is not a jumble of wires and metal but a living, evolving organism that has its own unconscious needs and tendencies. Johnson's new book, Where Good Ideas Come From, explains why certain spaces, from 18th-century coffeehouses to the World Wide Web, have an uncanny talent for encouraging innovative thinking.

Guest Post: Tom Levenson on Isaac Newton as the First Cosmologist | Cosmic Variance - 0 views

  • Newton knew what he had done. He was no accidental writer. A parabola, of course, is a curve that keeps on going – and that meant that at the end of a very long and very dense book, he lifted off again from the hard ground of daily reality and said, in effect, look: All this math and all these physical ideas govern everything we can see, out to and past the point where we can’t see anymore. Most important, he did so with implacable rigor, a demonstration that, he argued, should leave no room for dissent. He wrote “The theory that corresponds exactly to so nonuniform a motion through the greatest part of the heavens, and that observes the same laws as the theory of the planets and that agrees exactly with exact astronomical observations cannot fail to be true.” (Italics added).
  • To make his ambitions absolutely clear Newton used the same phrase for the title of book three. There his readers would discover “The System of the World.” This is where the literary structure of the work really comes into play, in my view. Through book three, Newton takes his audience through a carefully constructed tour of all the places within the grasp of his new physics. It begins with an analysis of the moons of Jupiter, demonstrating that inverse square relationships govern those motions. He went on, to show how the interaction between Jupiter and Saturn would pull each out of a perfect elliptical orbit; the real world, he says here, is messier than a geometer’s dream.

Apomediation - P2P Foundation - 0 views

  •  
    Apomediation is a new scholarly socio-technological term that characterizes the process of disintermediation (intermediaries are middlemen or "gatekeeper", e.g. health professionals giving "relevant" information to a patient, and disintermediation means to bypass them), whereby the former intermediaries are functionally replaced by apomediaries, i.e. network/group/collaborative filtering processes [Eysenbach, 2008 [WebCite] and 2007b]. The difference between an intermediary and an apomediary is that an intermediary stands "in between" (latin: inter- means "in between") the consumer and information/service, i.e. is absolutely necessary to get a specific information/service. In contrast, apomediation means that there are agents (people, tools) which "stand by" (latin: apo- means separate, detached, away from) to guide a consumer to high quality information/services/experiences, without being a prerequisite to obtain that information/service in the first place. The switch from an intermediation model to an apomediation model has broadimplications for example for the way people judge credibility, as hypothesized and elaborated in more detail elsewhere [

    RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own.

The Public Values Failures of Climate Science in the US by Ryan Meyer - Minerva, Volume... - 0 views

  •  
    "This paper examines the broad social purpose of US climate science, which has benefited from a public investment of more than $30 billion over the last 20 years. A public values analysis identifies five core public values that underpin the interagency program. Drawing from interviews, meeting observations, and document analysis, I examine the decision processes and institutional structures that lead to the implementation of climate science policy, and identify a variety of public values failures accommodated by this system. In contrast to other cases which find market values frameworks (the "profit as progress" assumption) at the root of public values failures, this case shows how "science values" ("knowledge as progress") may serve as an inadequate or inappropriate basis for achieving broader public values. For both institutions and individual decision makers, the logic linking science to societal benefit is generally incomplete, incoherent, and tends to conflate intrinsic and instrumental values. I argue that to be successful with respect to its motivating public values, the US climate science enterprise must avoid the assumption that any advance in knowledge is inherently good, and offer a clearer account of the kinds of research and knowledge advance likely to generate desirable social outcomes.

Mind-reading scan identifies simple thoughts - health - 26 May 2011 - New Scientist - 0 views

  •  
    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

Social networking's good and bad impacts on kids | KurzweilAI - 0 views

  •  
    Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

  •  
    A University of Zurich study 'proves' that a small group of companies - mainly banks - wields huge power over the global economy. The study is the first to look at all 43,060 transnational corporations and the web of ownership between them - and created a 'map' of 1,318 companies at the heart of the global economy. The study found that 147 companies formed a 'super entity' within this, controlling 40 per cent of its  wealth. All own part or all of one another. Most are banks - the top 20 includes Barclays and Goldman Sachs. But the close connections mean that the network could be vulnerable to collapse

Sociology and History: Shapin on the Merton Thesis « Ether Wave Propaganda - 1 views

  • Shapin observed that the link Merton drew between Puritanism and seventeenth-century English science was a matter of happenstance rather than determinism. According to Merton, science requires certain “values” and “sentiments” allowing intellectual individualism, and fostering not only an interest in the transcendent, but also secular improvement. It so happened that these values and sentiments were to be found in Puritan asceticism and sense of social obligation, which thus provided a social context in which science could develop. Definitively, this was not to say that Puritanism provided a unique source of these values and sentiments, or that science did not have other roots. It was obviously possible for science to develop in Catholic contexts as well, despite the less hospitable value system of Catholicism. The confluence of values simply seemed to promise some insight into the growth of science in a particular time and place.
  • Robert K. Merton’s “functionalist” sociology viewed “science” as a kind of Weberian ideal type — a form of thought that is identifiable by its peculiar, philosophically-defined characteristics. Merton’s sociology of science held that this thought could also be identified with social behaviors, characterized by a set of “norms”, which made the thought possible. The Merton Thesis (which slightly predates Merton’s enumeration of science’s norms) holds that the rise of science in early-modern England could be linked to the social behaviors valued by the Puritanism of that milieu. This was the subject of Merton’s PhD thesis and his 1938 book Science, Technology and Society in Seventeenth-Century England.

Researchers create self-assembling nanodevices that move and change shape on demand | K... - 0 views

  •  
    Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression. This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells. Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.

    What had been lacking until relatively recently was an overarching framework or theory through which to grasp the nature of consciousness. The lack of a general theory of consciousness, of how it comes to be that there is something that it is like to be, was really the last rational bastion of opposition to the scientific assertion that consciousness emerges from the brain.
