Internet Censorship Arms Race Gets New Weapon From Georgia Tech 75

Posted by timothy from the encode-it-in-your-drawlings dept.
coondoggie writes "Trying to get out in front of what they call a censorship arms race, a team of researchers has come up with technology that lets users exchange messages through heavily censored networks in countries such as China and North Korea in hidden channels via user-generated content sites such as Twitter or Flickr. Researchers with the Georgia Tech School of Computer Science will demo the technology known as Collage for the first time at next month's Usenix security conference and ideally have a working package the public can download by the end of August."

Pakistani Lawyer Wants Mark Zuckerberg Executed 1318

Posted by kdawson from the just-cut-the-wires dept.
Earthquake Retrofit sends along a piece from The Register reporting on a nightmare scenario of legal jurisdiction on the Internet: a Pakistani lawyer has filed blasphemy charges, carrying the death penalty, against Mark Zuckerberg and other Facebook executives (and the pseudonomous user who initiated the "Draw Muhammad" contest last month). Pakistani police have apparently opened an investigation, according to this Google translation of a BBC Urdu report."

Jupiter Is Missing a Belt 187

Posted by CmdrTaco from the what-holds-up-its-pants dept.
mbone writes "Jupiter just went through Superior Conjunction (i.e., went behind the Sun as seen from the Earth), so it has been out of view for a while. Now that it has returned, it is different — the South Equatorial Belt (SEB) is missing. The SEB has about 10 times the surface area of the Earth, so this is not a small change. Here are a series of photos of Jupiter's new look. The Great Red Spot typically inhabits the southern border of the SEB, but it doesn't seem to be affected by the change. It's a pity that this happened at Superior Conjunction, and that there is no satellite in Jupiter orbit, so details of the change are largely missing. The SEB has previously gone missing in 1973 and 1990. Since no one really knows what makes the Jovian belts, no one knows why they disappear either. If the belts are really just material from deeper layers coming to the surface, it is possible that the convection has stopped for some reason, or that high-altitude clouds have covered it over."

Oil Leak Could Be Stopped With a Nuke Screenshot-sm 799

Posted by samzenpus from the lesser-of-two-disasters dept.
An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

New Metamaterial Means More Efficient Solar Cells 94

Posted by CmdrTaco from the harness-this-stupid-sun dept.
ElectricSteve writes "Metamaterials are man-made substances designed to do some very weird things that natural materials don't. The path of a beam of light through a natural material like glass is predictable, but scientists from the California Institute of Technology have engineered an optical material that bends light in the wrong direction. This new negative-index metamaterial (NIM) could have several valuable uses including invisibility cloaking, superlensing (imaging nano-scale objects using visible light), and improved light collection in solar cells."

Cell Phones Could Sniff Out Deadly Chemicals 136

Posted by timothy from the feature-creep-could-be-nasty dept.
Hugh Pickens writes "Science Daily reports that Homeland Security's Science and Technology Directorate's Cell-All is an initiative to equip cell phones with a sensor capable of detecting deadly chemicals. A chip costing less than a dollar would be embedded in cell phones and programmed to alert either the cell phone carrier to the presence of toxic chemicals in the air, and/or a central station that can monitor how many alerts in an area are being received. While one alert might be a false positive, hundreds would indicate the need for evacuation. 'Our goal is to create a lightweight, cost-effective, power-efficient solution,' says Stephen Dennis, Cell-All's program manager. Does this always-on surveillance mean that the govenment can track your precise whereabouts whenever it wants? On the contrary, DHS says; Cell-All will operate only on an opt-in basis and will transmit data anonymously."

Photoshop CS5's Showpiece — Content-Aware Fill 378

Posted by timothy from the it's-like-stalin-was-never-there dept.
Barence writes "If you're looking for reasons to upgrade to Photoshop CS5 when it arrives, a new demo video might just persuade you. Narrated by Bryan O'Neil-Hughes, a product manager on the Photoshop team, the video shows the new content-aware fill tool, which has the potential to revolutionise the way you clean up photos. If you're not happy with an item in your picture, select it, delete it, and Photoshop will analyse the surrounding area and plug the gap as if it never existed."

Invisibility Cloak Created In 3-D 113

Posted by kdawson from the can-you-see-me-now dept.
An anonymous reader writes "Scientists have created the first device to render an object invisible in three dimensions. The 'cloak,' described in the journal Science (abstract; full text requires login), hid an object from detection using light of wavelengths close to those that are visible to humans. Previous devices have been able to hide objects from light travelling in only one direction; viewed from any other angle, the object would remain visible. This is a very early but significant step towards a true invisibility cloak." The "object" hidden in this work was a bump one micrometer high. The light used was just longer than the wavelengths our eyes detect. To get a visible-light cloak, the features of the cloaking metamaterial would need to be reduced in size from 300 nm to 10 nm.

Intel's Core i7-980X Six-Core Benchmarked 179

Posted by CmdrTaco from the faster-harder-better dept.
Ninjakicks writes "Although they won't hit store shelves for a few more weeks, today Intel has officially unveiled the new Core i7-980X Extreme processor. The Core i7-980X Extreme is based on Intel's 32nm Gulftown core, derived from their Nehalem architecture and sports six execution cores. The chip runs at a 3.33GHz clock frequency, that can jump up to 3.6GHz in Intel's Turbo Boost mode. This processor has a max TDP of 130W, which amazingly is the same as previous generation Core i7 quad-core CPUs. Of course, it's crazy fast too. Some may say that the majority of applications can't truly take advantage of the resources afforded by a six-core chip capable of processing up to 12 threads. However, the fact remains there are plenty of multi-threaded usage models and applications where the power of a CPU like this can be put to very good use."

We're all thinking it, so I'll say it: "Hey, let's let our government handle healthcare to increase effeciency"

uh, no. Some of us are thinking "hey, let's let our government handle healthcare because it's fucking criminal that for-profit entities are allowed to literally and figuratively bleed us dry in order to please their stockholders. And a big contributor to inadequacies in things like Medicare and the VA system stem from a lack of funds for improvements, either because people are too cheap and shortsighted to raise taxes or they have screwed up financial priorities like funding instead the biggest military on the planet so it can go bomb people overseas."

But then again I'm one of those filthy Commies who wants a single-payer healthcare system in the US, so feel free to disregard anything I say.

New Material Sets Stage For All-Optical Computing 53

Posted by timothy from the good-ping-times dept.
An anonymous reader writes with this excerpt from the International Business Times: "Researchers have made a new material that can be used to guide waves of light, a breakthrough that could lead to ultra-fast computing. Georgia Tech scientists are using specially designed organic dyes that can process and redirect light without the need to be converted to electricity first. ... 'For this class of molecules, we can with a high degree of reliability predict where the molecules will have both large optical nonlinearities and low two-photon absorption,' said [Georgia Tech School of Chemistry professor Seth] Marder." According to the article, using an optical router could lead to transmission speeds as high as 2,000 gigabits per second, five times faster than current technology.

Comcast Shoots For New Image, Rebranding As Xfinity 356

Posted by ScuttleMonkey from the what's-in-a-name dept.
artemis writes "Comcast is making efforts to repair and restore its 'former glory' by the act of transformation, rebranding itself as Xfinity. Hopefully step 2 is an actual change in quality and customer service. 'Comcast will use the Xfinity rebranding to talk up its improved customer service as well as its technical upgrades. “There’s a lot to be proud of,’’ said Steve Hackley, Comcast’s senior vice president for the Greater Boston region. “We want to take credit for it.’’ W2 Group’s Weber said such a rebranding is “a bit old-fashioned’’ and a new name is unlikely to impress consumers. “I think the public is smarter than that now,’’ he said.'"

DARPA Aims for Synthetic Life With a Kill Switch 295

Posted by ScuttleMonkey from the things-not-to-backport dept.
jkinney3 writes to mention that DARPA's mad scientists have undertaken a new program designed to create synthetic organisms, complete with a "kill switch." The project, dubbed BioDesign, is dumping $6 million into "removing the randomness of evolutionary advancement" by creating genetically engineered masterpieces. "Of course, Darpa's got to prevent the super-species from being swayed to do enemy work — so they'll encode loyalty right into DNA, by developing genetically programmed locks to create 'tamper proof' cells. Plus, the synthetic organism will be traceable, using some kind of DNA manipulation, 'similar to a serial number on a handgun.' And if that doesn't work, don't worry. In case Darpa's plan somehow goes horribly awry, they're also tossing in a last-resort, genetically-coded kill switch."
