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 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.

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.

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.

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.
Microsoft's other patent of interest is for "a 3D camera for determining distances to regions in a scene." That's not a new concept by any means, but this new bit of IP integrates all the functions of such an imager on a single chip. Essentially, it claims an image sensor, a light source to illuminate the scene being shot and a controller to gate the pixels on the sensor on and off and correct for inaccuracies caused by other light sources. It works by projecting the light source and determining the distance to various points based upon the time it takes for the light to bounce off the target and reach the camera sensor.

As you can see in the gallery above, each board has extensive plumbing to keep the SPARC silicon running at a manageable 32 - 35 degrees Celsius (90 - 95 Fahrenheit) under load. Underneath that copper cooling system lies four processors interspersed between 32 memory modules (with 2GB per module) and four ICCs lined up next to the board's rack interconnect ports.
Update: Turns out the K's power consumption resides around 13 megawatts, with a max consumption of 16MW at its current configuration. The facility in Kobe, Japan where K resides can deliver up to 24 megawatts, so expansion is possible, but none is currently planned.Permalink | | Email this | Comments
Turns out, when a one millimeter square membrane of gallium arsenide is placed parallel to a mirror in a vacuum chamber and bombarded with a laser beam, an optical resonator is created between them that oscillates the membrane. As the distance between the gallium arsenide and the mirror changes, so do the membrane's oscillations. And, at a certain frequency, the membrane is cooled to minus 269 degrees Celsius -- despite the fact that the membrane itself is being heated by the laser. So, lasers can both heat things up and cool them down simultaneously, and if that confuses you as much as it does us, feel free to dig into the science behind this paradoxical bit of research at the source below.

Immersiva is one of the most icon simulators in any metaverse, Bryn Oh‘s, (Immersiva’s creator), artistic soul flows, breathes, and evolves on a checker board grid that immerses you in lucid dreams and stories. Bryn’s free expression has had a profound effect on the residents of Second Life, and Immersiva is a grid favorite, it’s a place that always surprises.
So, it was such a surprise to hear, (from Bryn herself), that Immersiva was to shut down… with no good reason given. That news hurt, shocked and sadden me. I felt as if one of the last great SL creators was about to disappear from the metaverse, as so many have before her. Too many fantastic virtual artist have move out of SL, either to pursue real life artistic endeavors, or they immigrated to other open spaces. My heart broke at the news of Immersiva’s shutdown, and Bryn herself lamented that the experience was like the image of Marty and his siblings faded in the foreground.
It got me reminiscing on all the times I’ve paid a visit to Immersiva and other Bryn Oh builds around the Second Life grid. I have always been fascinated by her work, and I feel connected to the spirit she evokes. Both of my avatars have modeled with Immersiva in the background, and since Immersiva is a living and breathing simulator there is always something new to experience.
Bryn Oh’s Second Life builds seems like a faded memory now, I will charish these snapshots and archive them, I will not let Bryn’s Oh fade in vain! So Heartbreaking. =[
Huh? What was that Bryn? You found some funding? For another year and six months? Really?? …
YAY! \o/ … Yes! That’s excellent news! Immersiva is not going away yet, and in fact Bryn is asking for support to extend Immersiva’s breath and life. This is a great gift, Byrn! I’m so excited to see what you build, and the experiences you create. Check Out Byrn’s Crowd Funding site!
Byrn Oh is a true artist, she tells stories and brings them to life, she connects to your emotions and makes you think. Immersiva must stay open for as long as Bryn has something to say. Check out The Rabbicorn Story and Anna’s Many Murders.

Immersiva, created by Bryn Oh and donated to Second Life residents by Dusan Writer, is one of the most artistic and existential simulators in world. Byrn Oh’s work strikes deep cords in one’s soul, it opens the cracks into ones dreams and distant memories, while telling the stories of our collective childhood.
Traveling through the simulation and zooming into the detailed builds one gets the sense of slipping in between time and space, stepping through portals of blinding light and falling into voids. Immersiva is the place in our minds that time and space forgot, a place that is both run down and working, a place that allows the visitor to dream up their own reality and sense of what it all means.
The builds and landscape are beautifully crafted and Bryn Oh’s use of particle noise is perfectly executed. I’ve taken several trips to the sim and I will make many more, Ms. Oh likes to keep busy so she’s always adding and taking away from the experience, which keep the simulation exciting and new. Below you will find a slide show of my experience with Immersiva and machinima videos created by Ms. Oh herself.

I’ve made a few trips to AM Radio/IDIA Labs’ sims, and I’ve always found the builds to be surprising and delightful. AM Radio has the ability to create existential, spiritual and relatable sims. His detailed builds and amazing textures illustrate the ideas of falling in between spaces, alternate universes, parallel existences, portals and holes in the fabric of time and space. All the sims emulate rural-urban areas that have profound effects on modern culture, such as Dorothy’s Kansas wheatfields, or The Playa at Black Desert. AM Radio’s work conceptualizes the essence of augmented reality within a virtual world, and plants a seed of creativity on all who experience his series of sims. Mostly every one that explores AM Radio falls in love instantly, it’s simple yet profound landscapes strikes a cord with people from all backgrounds, and being able to slip into cracks of time and space give ones cords a disturbed edge.
The first AM Radio installation that I ever visited in world was
