gust5av writes "I'm working on a little script to provide very simple and easy to use steganography. I'm using bash together with cryptsetup (without LUKS), and the plausible deniability lies in writing to different parts of a container file. On decryption you specify the offset of the hidden data. Together with a dynamically expanding filesystem, this makes it possible to have an arbitrary number of hidden volumes in a file. It is implausible to reveal the encrypted data without the password, but is it possible to prove there is encrypted data where you claim there's not? If I give someone one file containing random data and another containing data encrypted with AES, will he be able to tell which is which?"

Freddybear writes "University of Pennsylvania's GRASP lab posted new video of their scary fast maneuverable quad-rotor drone. It can now fly through openings (hoops) which are themselves moving." The entire list of GRASP projects is worth crawling through.

telomerewhythere writes "A helicopter commissioned by Audi to film its autonomous Audi TT climbing Pikes Peak crashed early this morning. Four people on board were hurt, the pilot seriously. It's a surreal story — a manned vehicle crashes while the one climbing a mountain driven only by computers and sensors carries on. Here's more on the autonomous Audi, a project undertaken with the help of Stanford University."

MBCook writes "Turnkey CPU upgrades aren't just for mainframes anymore. According to Engadget, OEMs (including Gateway) are selling computers with the Intel Pentium G6951, which can have extra cache and hyper-threading enabled through a $50 software unlock called Intel Upgrade Service."

Zombie Puggle writes "Enterprise Storage Forum has an article contending that solid state disks will stay stuck at 20-25nm unless the materials and techniques used to design Flash drives changes, and soon. 'Anything smaller and the data protection and data corruption issues become so great that either the performance is abysmal, the data retention period doesn't meet JEDEC standards, or the cost increases. Though engineers are working on performance and density improvements via new technologies (they're also trying to drive costs down), these are fairly new techniques and are not likely to make it into devices for a while."

wooferhound writes "A portable laser backpack for 3D mapping has been developed at the University of California, Berkeley, where it is being hailed as a breakthrough technology capable of producing fast, automatic and realistic 3D mapping of difficult interior environments. ... The backpack is the first of a series of similar systems to work without being strapped to a robot or attached to a cart. At the same time, its data acquisition speed is very fast, as it collects the data while the human operator is walking; this is in contrast with existing systems in which the data is painstakingly collected in a stop-and-go fashion, resulting in days and weeks of data acquisition time. It utilizes novel sensor fusion algorithms that use cameras, lasers range finders and inertial measurement units to generate a textured, photo-realistic, 3D model that can operate without GPS input and that is a big challenge."

burnin1965 writes "Usually news articles about remote operated UAVs involve blowing people up. NASA's application takes a different path and uses the utility of the aircraft for scientific research that will benefit humanity. I haven't read much about NASA's Global Hawk lately, but they have been busy providing up-close access to the recent string of hurricanes."

An anonymous reader writes "Kawada Industries and the National Institute of Advanced Industrial Science and Technology have unveiled their new humanoid robot, HRP-4. The new humanoid stands 151cm tall and is much thinner than its predecessors. For Japan, HRP-4 is another step forward in creating useful mechanical workers to deal with a forthcoming shortage in the labor force and care for an aging population. HRP-4's creators expect to start selling the robot to universities and other research institutions as early as January 2011 for a price tag of $300,000, which is not that bad for a humanoid." The HRP-4s are a whole $100,000 cheaper than Willow Garage's PR2 (non-humanoid) robots, which became available earlier this month. The difference really adds up when building your robot army. Ron Moore could not be reached for comment.

holy_calamity writes "Pittsburgh startup Dynamics Inc has unveiled gadget-like credit cards with buttons, lights and even displays built into the same space as a conventional card. One card has two buttons on the front, which, when pressed, rewrite the data on the card's magnetic stripe, allowing it to act as multiple bank or credit cards in one. Another has several buttons and a display in place of the card's number. Only after entering a PIN is the magnetic stripe populated and the full card number revealed, and after a short time both go blank again for security." I wonder how long it'll be until somebody builds onboard biometrics into one of these things.

kkleiner writes "Honda has created two walking exoskeletons based on Asimo research that assist humans in walking. The Bodyweight Support Assist exoskeleton is a set of thin legs attached to a seat. Users sit on the seat and slip their feet into shoes on the robotic legs. This system supports bodyweight to assist people in walking and moving up and down steps. The other, Stride Management Assist, is a brace worn around the hips and thighs that provides added strength when flexing that joint. It's currently under development and being tested by 130 patients in the field. Both devices may prove to be valuable tools in helping the elderly maintain their mobility, assisting the disabled, and easing the stress on physical laborers."

adeelarshad82 writes "Intel has confirmed that the leaked HDCP master key protecting millions of Blu-ray discs and devices that was posted to the Web this week is legitimate. The disclosure means, in effect, that all Blu-ray discs can now be unlocked and copied. HDCP (High Definition Content Protection), which was created by Intel and is administered by Digital Content Protection LLP, is the content encryption scheme that protects data, typically movies, as they pass across a DVI or an HDMI cable. According to an Intel official, the most likely scenario for a hacker would be to create a computer chip with the master key embedded it, that could be used to decode Blu-ray discs."

ElectricSteve writes "Research conducted at the University of Bristol means a number of quantum computing algorithms may soon be able to execute calculations of a complexity far beyond what today's computers allow us to do. The breakthrough involves the use of a specially designed optical chip to perform what's known as a 'quantum walk' with two particles ... and it suggests the era of quantum computing may be approaching faster than the scientific establishment had predicted. A random walk – a mathematical concept with useful applications in computer science – is the trajectory of an object taking successive steps in a random direction, be it over a line (with only two possible directions) or over a multi-dimensional space. A quantum walk is the same concept, but translated to the world of quantum computing, a field in which randomness plays a central role. Quantum walks form an essential part of many of the algorithms that make this new kind of computation so promising, including search algorithms that will perform exponentially faster than the ones we use today."

tcd004 writes "Instead of using Detroit engineers or Silicon Valley bitheads, Virginia-based Edison2 relied on retired Formula 1 and Nascar engineers to build its entry for the X-prize. Relying on composite materials and titanium, the team assembled an ultra-lightweight car that provides all the comforts of a standard 4-passenger vehicle, but gets more than 100 mpg. The custom engineering goes all the way down to the car's lug nuts, which weigh less than 11 grams each. Amazingly, they expect a production version of the car should cost less than $20,000." Earlier today, in a Washington, DC ceremony, Edison2 received $5 million as the X-prize winner. Writes the AP (via Google) "Two other car makers will split $2.5 million each: Mooresville, N.C.-based Li-Ion Motors Corp., which made the Wave2, a two-seat electric car that gets 187 miles on a charge, and X-Tracer Team of Winterthur, Switzerland, whose motorcycle-like electric mini-car, the E-Tracer 7009, gets 205 miles on a charge. Both of those companies are taking orders for their cars."

snydeq writes "InfoWorld's Keith Schultz provides an in-depth comparative review of four data deduplication appliances to vet how well the technology stacks up against the rising glut of information in today's datacenters. 'Data deduplication is the process of analyzing blocks or segments of data on a storage medium and finding duplicate patterns. By removing the duplicate patterns and replacing them with much smaller placeholders, overall storage needs can be greatly reduced. This becomes very important when IT has to plan for backup and disaster recovery needs or when simply determining online storage requirements for the coming year,' Schultz writes. 'If admins can increase storage usage 20, 40, or 60 percent by removing duplicate data, that allows current storage investments to go that much further.' Under review are dedupe boxes from FalconStor, NetApp, and SpectraLogic."

GarryFre writes "It has been said that fusion is 50 years away for quite a few decades, but now work has actually been started. Digging has begun in the south of France on the planned site for France's first fusion reactor. A tokomak is a torus shaped magnetic confinement device which is necessary to withstand the temperatures associated with fusion that are so high, solid materials can't hold them. As such, the building represents the future core of ITER (International Thermonuclear Experimental Reactor.) It will be interesting to see if it takes 50 years to build it."

Barence writes Microsoft will deliver a touchscreen PC that is 'no thicker than a sheet of glass' within the next three years, according to the company's principal researcher. The device will be the next generation of Microsoft's Surface project, which currently houses a touchscreen PC in a deep cabinet that uses cameras to detect hand gestures and objects placed on the screen. According to Microsoft's Bill Buxton, 'Surface will become no thicker than a sheet of glass. It's not going to have any cameras or projectors because the cameras will be embedded in the device itself.' Microsoft is developing a new screen technology to make this possible. 'The best way to think about it is like a big LCD where there's a fourth pixel in every triad. So there's red, green, and blue pixels giving you light, and a fourth pixel which is a sensor that will capture stuff,' Buxton claims in an interview with The Globe and Mail."

Western Pennsylvania's shale oil deposits have lately attracted interest not only from companies who have been extracting some of that oil, but from locals who object to what they perceive as sharp dealing by the companies involved, favorable treatment by the state government, and environmental degradation as a result of the extraction. Some of the most visible of those protesters, it turns out, have been tracked (including "Web traffic") by Pennsylvania's own Homeland Security department, and that information about them has been shared not only within the department, but with the oil companies themselves. Homeland Security director James Powers defended the information shared with the oil companies as part of a triweekly bulletin, saying "We want to continue providing this support to the Marcellus Shale Formation natural gas stakeholders while not feeding those groups fomenting dissent against those same companies."

Last year we discussed news of a court ruling that established a set of guidelines for how investigators can enact search warrants involving electronically stored data. Essentially, it required authorities to specify the data for which they were searching, and to take precautions to avoid the collection of unrelated data, whether it was incriminating or not. Now, a federal appeals court has thrown out those guidelines despite agreeing with the conclusion that investigators must only collect data specified in a warrant. Instead, the ruling (PDF) leaves us with a plea for "greater vigilance on the part of judicial officers in striking the right balance between the government’s interest in law enforcement and the right of individuals to be free from unreasonable searches and seizures."

njkobie writes "Intel has officially unveiled Sandy Bridge, its latest platform architecture, at the first day of IDF in San Francisco. The platform is the successor to the Nehalem/Westmere architecture and integrates graphics directly onto the CPU die. It also upgrades the Turbo Mode already seen in Core i5 and i7 processors to achieve even greater speed improvements. Turbo Mode on Sandy Bridge processors can now draw more than the chip's nominal TDP where the system is cool enough to do so safely, enabling even greater boosts in core speeds than those seen in Westmere. No details of specific products have been made available, but Intel has confirmed that processors built on the new architecture will be referred to as 'second generation Core processors,' and are expected to go on sale in early 2011. In 2012 it is due to be shrunk to a 22nm process, under the name Ivy Bridge."
