First, Pandora does have an oxygen atmosphere, or how else could you explain the burning torch that Jake Sully lights up in self-defense against the wulf-like creatures at night?

Second, the floating mountains are explained by assuming that the rock is made up of superconducting material ("Unobtainium") and that the flux they keep talking about is actually a strong magnetic field. Superconductors tend to hover in magnetic fields, you know.

An Open Source Compiler From CUDA To X86-Multicore 71

Posted by timothy on Wednesday December 23, 2009 @03:06PM from the abstraction-gains-a-layer dept.

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."

An anonymous reader writes: A month ago, ticalc.org reported smart factoring of the 512-bit RSA key used by TI to sign their TI-83+ OS, which opens the door to seamless installation of open-source third-party OS on TI-83+ calculators. Since then, two other keys found in other TI calculators have been factored by a distributed effort. Several days ago, TI sent DMCA takedown notices to several sites mentioning the keys and their factors. All three keys factored so far have been posted to Wikileaks, and the effort to factor the remaining ones is going on.

Getting an accurate world elevation map essentially for free is really cool. Previously you had to get one of the commercial scenery DVDs that would set you back at least $50.

After all, having realistic mointain terrain makes flying much nicer and recognizing land features will be much easier. Then map some Sat terrain on top, for example with the Tileproxy application and everything will look just real.
