DX11 Tested Against DX9 With Dirt 2 Demo 201

Posted by Soulskill from the shadows-with-shadows dept.
MojoKid writes "The PC demo for Codemasters' upcoming DirectX 11 racing title, Dirt 2, has just hit the web and is available for download. Dirt 2 is a highly-anticipated racing sim that also happens to feature leading-edge graphic effects. In addition to a DirectX 9 code path, Dirt 2 also utilizes a number of DirectX 11 features, like hardware-tessellated dynamic water, an animated crowd and dynamic cloth effects, in addition to DirectCompute 11-accelerated high-definition ambient occlusion (HADO), full floating-point high dynamic range (HDR) lighting, and full-screen resolution post processing. Performance-wise, DX11 didn't take its toll as much as you'd expect this early on in its adoption cycle." Bit-tech also took a look at the graphical differences, arriving at this conclusion: "You'd need a seriously keen eye and brown paper envelope full of cash from one of the creators of Dirt 2 to notice any real difference between textures in the two versions of DirectX."

The State of Ruby VMs — Ruby Renaissance 89

Posted by Soulskill from the take-your-pick dept.
igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Phoronix Releases Linux Benchmarking Distribution 31

Posted by timothy from the medium-infrastructure dept.
Bitnit writes "Phoronix has released a major update to their automated Linux benchmarking software, the Phoronix Test Suite, and more interestingly they have released their own distribution that's designed for hardware testing and benchmarking on Linux. With PTS Desktop Live they provide this Linux distribution that's to run only from a live environment off a DVD / USB key and then allows their benchmarking software to run — and only that — on this standardized software stack, which makes hardware comparisons a lot easier."

Facebook Lets Advertisers Use Pictures Without Permission 260

Posted by kdawson from the controlling-rights-to-your-face dept.
Krokz sends in an LA Times piece that begins "A warning is bouncing through cyberspace today, landing on the Facebook statuses of many of the social networking site's users. The message: 'Facebook has agreed to let third party advertisers use your posted pictures without your permission.' It continues with a prescription of how you can protect your photos." The attention-grabbing incident in this furor involved a married woman, whose photo appeared in an ad for a dating service that was presented to her husband to view. Fortunately, both husband and wife had a sense of humor about it.

Toys You Control With Your Brain 83

Posted by samzenpus from the but-thinking-is-hard dept.
Kaliann writes "Toys that respond to brainwaves are the next generation of unique user interfaces. The Washington Post looks at the current market appeal and future uses of technology that can meaningfully respond to the thoughts of a user. Currently the toys have a fairly simple basic idea: the harder you concentrate the more the object moves. A sensor on the forehead picks up brain waves that are associated with concentration, then levitates a ball in response: basic biofeedback. While this may seem to be a rather humble beginning, progress in this field could have astounding consequences in the advancement of technologies devoted to thought-controlled devices. As the author points out, Jedi Beer Pong is within our grasp."

Analyzing YouTube's Audio Fingerprinter 116

Posted by timothy from the streeeeeehtch-thiiiiingsss-ouuuuuut dept.
Al Benedetto writes "I stumbled across this article which analyzes the YouTube audio content identification system in-depth. Apparently, since YouTube's system has no transparency, the behaviors had to be determined based on dozens of trial-and-error video uploads. The author tries things like speed/pitch adjustment, the addition of background noise, as well as other audio tweaks to determine exactly what you'd need to adjust before the fingerprinter started mis-identifying material. From the article: 'When I muted the beginning of the song up until 0:30 (leaving the rest to play) the fingerprinter missed it. When I kept the beginning up until 0:30 and muted everything from 0:30 to the end, the fingerprinter caught it. That indicates that the content database only knows about something in the first 30 seconds of the song. As long as you cut that part off, you can theoretically use the remainder of the song without being detected. I don't know if all samples in the content database suffer from similar weaknesses, but it's something that merits further research.'"

Scientists Discover Exoplanet Less Than Twice the Mass of Earth 201

Posted by Soulskill from the it's-so-small dept.
Snowblindeye writes with this excerpt from the European Southern Observatory: "Well-known exoplanet researcher Michel Mayor today announced the discovery of the lightest exoplanet found so far. The planet, 'e,' in the famous system Gliese 581, is only about twice the mass of Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist. Planet Gliese 581 e orbits its host star — located only 20.5 light-years away in the constellation Libra ('the Scales') — in just 3.15 days. 'With only 1.9 Earth-masses, it is the least massive exoplanet ever detected and is, very likely, a rocky planet,' says co-author Xavier Bonfils from Grenoble Observatory. Being so close to its host star, the planet is not in the habitable zone. But another planet in this system appears to be. ... The planet furthest out, Gliese 581 d, orbits its host star in 66.8 days. 'Gliese 581 d is probably too massive to be made only of rocky material, but we can speculate that it is an icy planet that has migrated closer to the star,' says team member Stephane Udry. The new observations have revealed that this planet is in the habitable zone, where liquid water could exist. '"d" could even be covered by a large and deep ocean — it is the first serious "water world" candidate,' continued Udry."

Developing Battery Replacement Infrastructure For Electric Cars 369

Posted by Soulskill from the not-free-of-charge dept.
FathomIT sends in a NY Times profile of Shai Agassi, owner of a company named Better Place, who is working to build the infrastructure to support large numbers of small-scale charging spots for electric cars, as well as fast, automated battery swap stations. "The robot — a squat platform that moves on four dinner-plate-size white wheels — scuttled back and forth along a 20-foot-long set of metal rails. At one end of the rails, a huge blue battery, the size of a large suitcase, sat suspended in a frame. As we watched, the robot zipped up to the battery, made a nearly inaudible click, and pulled the battery downward. It ferried the battery over to the other end of the rails, dropped it off, picked up a new battery, hissed back over to the frame and, in one deft movement, snapped the new battery in the place of the old one. The total time: 45 seconds."
