asgard4 writes "In recent years GPUs have become powerful computing devices whose power is not only used to generate pretty graphics on screen but also to perform heavy computation jobs that were exclusively reserved for high performance super computers in the past. Considering the vast diversity and rapid development cycle of GPUs from different vendors, it is not surprising that the ecosystem of programming environments has flourished fairly quickly as well, with multiple vendors, such as NVIDIA, AMD, and Microsoft, all coming up with their own solutions on how to program GPUs for more general purpose computing (also abbreviated GPGPU) applications. With OpenCL (short for Open Computing Language) the Khronos Group provides an industry standard for programming heavily parallel, heterogeneous systems with a language to write so-called kernels in a C-like language. The OpenCL Programming Guide gives you all the necessary knowledge to get started developing high-performing, parallel applications for such systems with OpenCL 1.1."

writes "SOPA has been sent back to the drawing board. 'The move came shortly after the Senate postponed a key vote on the companion PIPA bill scheduled for next week and amid calls for consensus before Congress moves forward on any legislation to address the problem of foreign piracy websites,' as written by the Los Angeles Times today. Hopefully the next draft of this bill will create a better foundation to stop piracy and not just assert control over the internet."
Support for the bill eroded on Wednesday as several of its co-sponsors withdrew their support
. The issue is not over, however; statements were issued by both Senator Patrick Leahy
and Rep. Lamar Smith
indicating that they still want to find solutions to online piracy, and Smith also wrote an editorial piece for CNN to explain why he thinks such legislation is necessary
. The SOPA issue was raised at the recent GOP debate, and all four candidates spoke against it

writes "Megaupload's shutdown poses an interesting question: What happens to all the files that were stored on the servers? XDA-Developers, for example, has more than 200,000 links to Megaupload — and this morning, they're all broken, with very little hope of them returning. What happens if a similar service, like Dropbox, gets shut down — either through bankruptcy, or federal take-down? Will you be given a chance to download your files, or helped to migrate them to another similar service? What about data stored on enterprise services like Azure or AWS — are they more safe?"
And if you're interested, the full indictment against Megaupload is now available
