In October 2013, VICE News was invited to visit the infamous tech mogul and creator of Megaupload, Kim Dotcom, at his palatial property in New Zealand. Even though Kim is under house arrest—since he’s at the center of history’s largest copyright case—he’s still able to visit a recording studio in Auckland. So check out this brand new documentary we made at Kim’s mega-mansion and in the studio where our host, Tim Pool, got to lay down some backup vocals for Kim’s upcoming EDM album while talking about online surveillance, file-sharing, and Kim’s controversial case.

Julian Assange’s 2014 Message to System Administrators

Posted on December 31, 2013 in Culture, Grids, Networks by dulce303

Julian Assange Calls on Computer Hackers to Unite Against NSA Surveillance:

Those high-tech workers, we are a particular class, and it’s time that we recognized that we are a class and looked back in history and understood that the great gains in human rights and education and so on that were gained through powerful industrial work as we formed the backbone of the economy of the 20th century, I think we have that same ability, but even more so, because of the greater interconnection that exists now, economically and politically, which is all underpinned by system administrators. And we should understand that system administrators are not just those people who administer one unique system or another; they are the people who administer systems. And the system that exists globally now is created by the interconnection of many individual systems. And we are all, or many of us, are part of administering that system, and have extraordinary power, in a way that is really an order of magnitude different to the power industrial workers had back in the 20th century.

And we can see that in the cases of the famous leaks that WikiLeaks has done or the recent Edward Snowden revelations, that it’s possible now for even a single system administrator to have a very significant change to the—or rather, apply a very significant constraint, a constructive constraint, to the behavior of these organizations, not merely wrecking or disabling them, not merely going out on strikes to change policy, but rather shifting information from an information apartheid system, which we’re developing, from those with extraordinary power and extraordinary information, into the knowledge commons, where it can be used to—not only as a disciplining force, but it can be used to construct and understand the new world that we’re entering into.

Now, Hayden, the former director of the CIA and NSA, is terrified of this. In Cypherpunks, we called for this directly last year. But to give you an interesting quote from Hayden, possibly following up on those words of mine and others: “We need to recruit from Snowden’s generation,” says Hayden. “We need to recruit from this group because they have the skills that we require. So the challenge is how to recruit this talent while also protecting ourselves from the small fraction of the population that has this romantic attachment to absolute transparency at all costs.” And that’s us, right?

So, what we need to do is spread that message and go into all those organizations—in fact, deal with them. I’m not saying don’t join the CIA. No, go and join the CIA. Go in there. Go into the ballpark and get the ball and bring it out—with the understanding, with the paranoia, that all those organizations will be infiltrated by this generation, by an ideology that is spread across the Internet. And every young person is educated on the Internet. There will be no person that has not been exposed to this ideology of transparency and understanding of wanting to keep the Internet, which we were born into, free. This is the last free generation.

The coming together of the systems of governments, the new information apartheid across the world, the linking together, is such that none of us will be able to escape it in just a decade. Our identities will be coupled to it, the information sharing such that none of us will be able to escape it. We are all becoming part of the state, whether we like it or not, so our only hope is to determine what sort of state it is that we are going to become part of. And we can do that by looking and being inspired by some of the actions that produced human rights and free education and so on, by people recognizing that they were part of the state, recognizing their own power, and taking concrete and robust action to make sure they lived in the sort of society that they wanted to, and not in a hellhole dystopia.

Quantum computing, no cooling required.

ScienceDaily (July 3, 2012) — It’s a challenge that’s long been one of the holy grails of quantum computing: how to create the key building blocks known as quantum bits, or qubits, that exist in a solid-state system at room temperature.

Most current systems, by comparison, rely on complex and expensive equipment designed to trap a single atom or electron in a vacuum and then cool the entire system to close to absolute zero.
A group of Harvard scientists, led by Professor of Physics Mikhail Lukin and including graduate students Georg Kucsko and Peter Maurer and postdoctoral researcher Christian Latta, say they’ve cracked the problem, and they did it by turning to one of the purest materials on Earth: diamonds.
Using a pair of impurities in ultra-pure, laboratory-grown diamonds, the researchers were able to create quantum bits and store information in them for nearly two seconds, an increase of nearly six orders of magnitude over the life span of earlier systems. The work, described in the June 8 issue of Science, is a critical first step in the eventual construction of a functional quantum computer, and has a host of other potential applications.

Quantum computing, no cooling required: Room-temperature quantum bits store data for nearly two seconds.

New 3D printer could create nano-devices in minutes

Researchers at the Vienna University of Technology (TU Vienna) have developed a 3D printing technology that can quickly print detailed objects in nanoscale using a process called two-photon lithography. It’s fast, too: the precision required to print objects with features measured in hundreds of nanometers in width meant the speed of previous attempts at printing nanoscale objects were measured in millimeters per second. In contrast, the TU Vienna team’s 3D printer is capable of printing lines of resin at a rate of five meters per second. In a demonstration shown in the video below, the team was able to print a nanoscale model of a 300-micrometer long Formula 1 racecar—made from 100 layers of resin, each consisting of approximately 200 individual lines—in four minutes.

The new process, developed as part of the European Commision’s PhoCam program for developing “factories of the future,” could make it practical and affordable to print intricate nano-scale structures for use in microscopic machinery and medical applications. One of those is “scaffolds” for promoting the growth of custom-made living tissues from cells, giving cells a structure to stick to. “The technique already showed good applicability for fabricating 3D environments for cells,” TU Vienna researcher Jan Torgersen told Ars in an e-mail exchange about the research.

Torgensen added that since the two-photon process isn’t limited to printing in layers, but can draw lines in three dimensions, it can be used to embed and connect objects as well. For example, he said, the team has already successfully fabricated nanoscale optical waveguides into an existing electrical matrix. “These waveguides are very promising for various optoelectronic applications,” he said.

Power Felt gives a charge

Posted on February 28, 2012 in Grids, Mixed Reality by dulce303

New technology from Center of Nanotechnology and Molecular Materials holds promise in thermoelectrics

When Wake Forest graduate student Corey Hewitt (Ph.D. ’13) touches a two-inch square of black fabric, a meter goes berserk. Simply by touching a small piece of Power Felt – a promising new thermoelectric device developed by a team of researchers in the Center for Nanotechnology and Molecular Materials – he has converted his body heat into an electrical current.

Comprised of tiny carbon nanotubes locked up in flexible plastic fibers and made to feel like fabric, Power Felt uses temperature differences – room temperature versus body temperature, for instance – to create a charge.

“We waste a lot of energy in the form of heat. For example, recapturing a car’s energy waste could help improve fuel mileage and power the radio, air conditioning or navigation system,” Hewitt says. “Generally thermoelectrics are an underdeveloped technology for harvesting energy, yet there is so much opportunity.”

The research appears in the current issue of Nano Letters, a leading journal in nanotechnology. Potential uses for Power Felt include lining automobile seats to boost battery power and service electrical needs, insulating pipes or collecting heat under roof tiles to lower gas or electric bills, lining clothing or sports equipment to monitor performance, or wrapping IV or wound sites to better track patients’ medical needs.

“Imagine it in an emergency kit, wrapped around a flashlight, powering a weather radio, charging a prepaid cell phone,” says David Carroll, director of the Center for Nanotechnology and Molecular Materials and head of the team leading this research. “Literally, just by sitting on your phone, Power Felt could provide relief during power outages or accidents.”

Cost has prevented thermoelectrics from being used more widely in consumer products. Standard thermoelectric devices use a much more efficient compound called bismuth telluride to turn heat into power in products including mobile refrigerators and CPU coolers, but it can cost $1,000 per kilogram. Like silicon, researchers liken its affordability to demand in volume and think someday Power Felt would cost only $1 to add to a cell phone cover.

Currently Hewitt is evaluating several ways to add more nanotube layers and make them even thinner to boost the power output. Although there’s more work to do before Power Felt is ready for market, he says, “I imagine being able to make a jacket with a completely thermoelectric inside liner that gathers warmth from body heat, while the exterior remains cold from the outside temperature. If the Power Felt is efficient enough, you could potentially power an iPod, which would be great for distance runners. It’s pretty cool to think about, and it’s definitely within reach.” Currently Wake Forest is in talks with investors to produce Power Felt commercially.

Congress passes bill giving the FAA $11 billion to get off radar, onto GPS

Posted on February 8, 2012 in Grids by dulce303

It took awhile, and the price tag is quite a bit steeper than previously thought (shocking, right?), but the FAA is finally getting the funding it needs to bring the nation's air traffic control system up to date. Congress just passed the bill to make it happen, allotting $11 billion to the FAA to upgrade the nation's 35 busiest airports air traffic controls from radar to GPS. The deadline for the conversion is June 2015, and when complete, it'll allow for more precise positioning of aircraft -- GPS pings for the planes' locations every second, while radar updates their locations every 6 to 12 seconds. With such technology enabled, airplanes will be able to take-off and land more closely together while utilizing steeper descents than is currently possible to conserve fuel. So, now that we've got the new traffic control system to improve airline punctuality, we just need the FAA and the FCC to team up and eliminate the "Terrible 10,000 feet" and flying might actually be fun.

AMD’s new plan: focus on tablets, cloud computing and developing markets

Posted on February 2, 2012 in Grids, Networks by dulce303

Chipzilla has long been atop the PC chip manufacturing mountain, with AMD running a rather distant second. That's why AMD's new top man, Rory Read, plans to move the company in a more mobile direction. Speaking at the company's analyst day, Read stated that the chipmaker will focus on outflanking Intel in the tablet space and by growing its business in cloud computing and emerging markets like China (read: entry-level PCs and devices). As to whether AMD would venture into the smartphone space, Read was quite clear in stating that there were no plans to do so. But, he did make mention of being flexible when it came to chip architecture, including using 3rd party IP in developing new silicon -- so a switch to ARM may not be out of the question. How will AMD accomplish its new goals? By focusing on execution of its technology rather than trying to be on the bleeding edge -- sound familiar?

MasterCard reveals roadmap for our electronic payment future: EMV in, magnetic strips out

Posted on January 31, 2012 in Grids, Networks, Uncategorized by dulce303

MasterCard reveals roadmap for EMV electronic payments It's been over fifteen years since MasterCard, Visa and Europay developed EMV technology to make your credit cards more secure, but it has yet to really catch on here in the US. However, MasterCard has created a master plan to help usher in the EMV era and sound the death knell for the magnetic strip. Why? The EMV infrastructure is far more fraud-resistant because each transaction is authenticated dynamically using cryptographic algorithms and a user-specific PIN. That's why MasterCard plans to help build out the EMV POS infrastructure by April of next year and have its secure e-payment system functioning at ATMs, online and with its myriad mobile payment options as well. For now, the nuts and bolts of how the credit card firm plans to bring its plan to fruition are few, but more details will be forthcoming, and there's a bit more info at the source and PR below.
