Vigile writes "A big shift in the way graphics cards and gaming performance are tested has been occurring over the last few months, with many review sites now using frame times rather than just average frame rates to compare products. Another unique testing methodology called Frame Rating has been started by PC Perspective that uses video capture equipment capable of recording uncompressed high resolution output direct from the graphics card, a colored bar overlay system and post-processing on that recorded video to evaluate performance as it is seen by the end user. The benefit is that there is literally no software interference between the data points and what the user sees, making it is as close to an 'experience metric' as any developed. Interestingly, multi-GPU solutions like SLI and CrossFire have very different results when viewed in this light, with AMD's offering clearly presenting a poorer, and more stuttery, animation."
derGoldstein writes "We've seen some very impressive aerobatics performed by quadrocopters before, but this is getting ridiculous. Robohub points to the latest advancement from the Flying Machine Arena, which developed algorithms that allow quadrocopters to juggle an inverted pendulum. One of the researchers working on it said, 'We started off with some back-of-the-envelope calculations, wondering whether it would even be physically possible to throw and catch a pendulum. This told us that achieving this maneuver would really push the dynamic capabilities of the system. As it turned out, it is probably the most challenging task we've had our quadrocopters do. With significantly less than one second to measure the pendulum flight and get the catching vehicle in place, it's the combination of mathematical models with real-time trajectory generation, optimal control, and learning from previous iterations that allowed us to implement this.'"
cylonlover writes "If Joseph Zawodny, a senior scientist at NASA's Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment."
rtoz writes "Ohio State students have come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air. This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory."
First time accepted submitter Lirodon writes "Just when you thought Google's rumored Chrome OS laptop, the Chromebook Pixel, was an elaborate fake, think again. This high-end Chromebook with a 12.85-inch high resolution touchscreen (available in both Wi-Fi only and Verizon LTE versions) and an Intel Core i5 processor under the hood is super fancy, and also super expensive: starting at $1299. Would you want to pay that much for what is essentially a premium netbook?" Engadget has a hands-on with the device.
CES named Eyetech has a solution for this problem: an eye tracker system that can control your computer or TV (or whatever) purely through eye movements. This isn't something you buy on a whim; the system costs $3000. That's a lot, but Eyetech claims they were the first ones to produce a high-accuracy eye tracker for less then $20,000. Obviously, this is a boon to profoundly disabled people. But Eyetech's Keith Jackson says, in the video, that they also have customers who use Eyetech instead of a mouse because of carpal tunnel syndrome, and that with voice recognition and on-screen keyboards -- and Eyetech, of course -- you can use your computer without (literally) lifting a finger.
New submitter sc30317 writes "My house got robbed on Friday, and all of our electronics got stolen. Everything. Now, I have to go out and buy all new electronics with the insurance money. We had five TVs (don't ask), three laptops, a Bose Sound dock with iPod, a digital camera, and a desktop stolen. It's looking like I am going to get around $10K from the insurance company to replace everything. What would you do if you had to replace ALL of your technology in your house at once? I'm thinking: replace TVs; nice Desktop; new speakers; and new, cool stuff I don't know about (suggestions welcome). I already added a DVR security system, so hopefully the new things won't get burgled! Looking for suggestions to utilize my money in order to get the best stuff. Also, no Windows computers allowed in my house."
New submitter Nyder writes "In a move that is sure to bring tears to the eyes of kids everywhere, Connecticut State Senator Toni Harp proposed a bill in January that would ban anyone younger than 18 from playing 'violent point-and-shoot' video games in arcades or other public establishments. 'The bill also called for research into the effects of violent video games on young minds, through a committee called the Violent Video Game Task Force within the Department of Children and Families. The task force would advise the Governor and General assembly on state programs that "may reduce the effects of violent video games on youth behavior," suggesting before the research was done that violent video games have an effect on children's actions.' Hopefully this won't pass; I guess the video game lobby hasn't paid this Senator enough 'funds' for her campaign."
Several readers sent word of a new addition to the 3-D printing industry. Most 3-D printers are roughly the size of regular printers, and require design files on the computer to guide the extruder. Now there's a much smaller and much simpler alternative: the 3Doodler pen, which lets you draw 3-D objects by hand. The people making the pen set up a Kickstarter project yesterday with a $30,000 goal. They reached that within hours, and now have pledges exceeding $800,000. "The 3Doodler pen is 180mm by 24mm. The pen weighs less than 200 grams or 7 ounces (the weight of a typical apple), although the exact weight will depend on the final shell specifications once in production. And we are using a universal power supply, so provided you have the correct adapter for your country, 3Doodler will work just fine on 110v or 240v. ... While the plastic extruded from 3Doodler is safe to touch once it has left the pen, the pen itself has a metal tip that can get as hot as 270C." The pen uses the same ABS/PLA plastic as most 3-D printers, and they're planning to host stencil designs on their website so that users have patterns to sketch from.
An anonymous reader writes "Whether or not you're an owner of Microsoft's Xbox 360, chances are you find the Kinect accessory intriguing, since you don't even need the company's console to use it. That's why there's so much excitement surrounding the console's successor, codenamed Durango: it will feature Kinect 2.0, the specifications for which allegedly leaked today. The new device will reportedly be able to track players with a height of one meter, feature a mode for both seated and standing players, detect hand states (such as open or closed), as well as extra and rotated joints. As for improved features, it will be able to supposedly track six rather than two active players, occluded joints, and sideways poses. This will all be possible thanks to an increased field of vision, 1920×1080 color stream, 512×424 depth stream, an added infrared stream, USB 3.0, and 60ms latency."
kkleiner writes "Planetary Resources last year boldly claimed that they would build a futuristic business out of mining space asteroids. To that end, the firm recently completed the Arkyd-100 satellite prototype. The satellite will use its telescope to look for suitable near-Earth asteroids from low-Earth orbit. Later expeditions will rocket out to prospective real estate, do spectral analysis, and if the asteroid contains valuable resources, lay claim with a beacon."
KermMartian writes "The TI-84 Plus C Silver Edition isn't the first color-screen graphing calculator, or even TI's first color calculator, but it's a refresh of a 17-year-old line that many have mocked as antiquated and overpriced. From an advanced review model, the math features look familiar, solid, and augmented with some new goodies, while programming looks about on par with its siblings. The requisite teardown uncovers the new battery, Flash, ASIC/CPU, and LCD used in the device. Although there are some qualms about its speed and very gentle hardware upgrades beyond the screen, it looks to be an indication that TI will continue this inveterate line for years to come." Lots of screenshots and pictures of the innards too.
rtoz writes with a quick bite from rtoz.org about Google's latest news about Project Glass: "Google has released video preview of its forthcoming Google Glass wearable headset, providing a fresh, and more realistic look at the device's user interface. Based on the demo, Google Glass will allow users to receive and execute onscreen directions, send voice-controlled messages, and search the web through speech. The UI also includes voice-controlled photos, and suggests that the device will offer onscreen translation support. And, it looks like the Google Glass will be water-resistant. Google has previously said it is aiming to launch Glass by early 2014, though it is already pushing out developer editions priced at $1,500." They're looking for developers, but only if you're hip enough.
An anonymous reader writes "We've watched patents slow down the smartphone and tablet markets. We've seen patent claims thrown against Linux, Android, and countless other software projects. Now, as 3-D printing becomes more capable and more affordable, it seems a number of patents threaten to do the same to the hobbyist and tinkerer crowd. Wired has highlighted some of the most dangerous ones, including: a patent on soluble print materials that support a structure while it's being printed; a ridiculously broad patent on distributed rapid prototyping, which could affect "every 3-D printing service that has launched in the past few years"; and an 18-year-old patent on 3-D printing using a powder and a binding material, held by MIT."
Vigile writes "NVIDIA's new GeForce GTX TITAN graphics card is being announced today and is utilizing the GK110 GPU first announced in May of 2012 for HPC and supercomputing markets. The GPU touts computing horsepower at 4.5 TFLOPS provided by the 2,688 single precision cores, 896 double precision cores, a 384-bit memory bus and 6GB of on-board memory doubling the included frame buffer that AMD's Radeon HD 7970 uses. With a make up of 7.1 billion transistors and a 551 mm^2 die size, GK110 is very close to the reticle limit for current lithography technology! The GTX TITAN introduces a new GPU Boost revision based on real-time temperature monitoring and support for monitor refresh rate overclocking that will entice gamers and with a $999 price tag, the card could be one of the best GPGPU options on the market." HotHardware says the card "will easily be the most powerful single-GPU powered graphics card available when it ships, with relatively quiet operation and lower power consumption than the previous generation GeForce GTX 690 dual-GPU card."
