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."

fortapocalypse writes "Yohanes Nugroho just released WiiApple, an Apple IIe Emulator for Wii. While the sound doesn't work, some games are playable (he shows a screenshot of Epyx Winter Games as well the execution of a program he wrote in BASIC). He's also released the source code. Using WiiApple requires the Homebrew Channel, which we have discussed in the past."

subcomdtaco writes with this snippet from a story in the NYTimes: "Dr. [Robert] Gaskell, with software he developed over a quarter-century of trial and error, can process hundreds of images in a few hours, slap them atop one another electronically like coats of paint and produce a topographical map so detailed that you often need a pair of 3-D glasses to appreciate what he has done. At 63, Dr. Gaskell has become the Captain Cook of space. Dr. Gaskell calls what he does 'stereophotoclinometry.' [PDF] Ideally he needs at least three images of the target landscape, usually taken by an orbiting spacecraft or a probe on a flyby to another destination. Only in rare cases can telescope images provide enough detail. The sun angle must be different for each exposure so each image shows different shadows. By comparing the shadows, the software calculates slopes, which yield the altitudes of target features. The computer solves the equation in three dimensions, producing a patchlike topographical maplet."

Vrst1013 notes a Business Week account of a government report examining fraud in the H-1B program. The US Citizenship and Immigration Services just released a report to members of the Senate Judiciary Committee examining issues with fraud and technical violations within this program. Based on a sample size of 246 H-1B petitions, 13.4 percent showed fraud and 7.3 percent showed technical violations, for an overall violation rate of 20.7 percent. There was slso evidence of payment below the prevailing wage, offers of non-existent jobs, and fraudulent documentation. "'The report makes it clear that the H-1B program is rife with abuse and misuse,' says Ron Hira, [a professor] at the Rochester Institute of Technology ... However, both Presidential candidates, Senator Barack Obama and Senator John McCain, have said they support expanding the program."
