The Khronos Group recently announced that the WebGL 1.0.1 specification is compliant across mobile and desktop systems on a number of platforms. Chrome 25 and Firefox 19 support WebGL 1.0.1 on Windows, Mac, and Linux operating systems. Further, mobile devices with Tegra SoCs can tap into WebGL using a WebGL-enhanced Android browser.
Additionally, the WebGL 1.0.2 specification and its extensions have been submitted for ratification, and is expected to be formally released in April. According to the press release, the following features are being rolled into the WebGL 1.0.2 specification:
- "adds many clarifications for specification behavioral precision
- mandates support for certain combinations of framebuffer formats, to ease developer adoption;
- clarifies interactions with the encompassing HTML5 platform, including the browser compositor and high-DPI displays;
- dramatically increases the number of conformance tests to roughly 21,000 to improve both the breadth and depth of test coverage - thanks principally to work by Gregg Tavares at Google and the OpenGL ES working group."
Khronos President and NVIDIA Vice President of Mobile Content Neil Trevett stated that "The close cooperation between browser and silicon vendors to ensure the GPU is being reliably and securely exposed to the Web is ongoing proof that Khronos is a highly productive forum to evolve this vital Web standard." Meanwhile, WebGL Working group chair Ken Russell indicated that WebGL 1.0.2 is "a major milestone in bringing the power of the GPU to the Web.”
Although there are security concerns to consider, WebGL does open up some interesting opportunities for new web services. The full press release can be found here.

The popular, if elusive, Raspberry Pi had the original intent to be a cheap computer capable of introducing kids to programming. In furthering that goal, Adafruit has been working on a programming IDE (Integrated Development Environment) with a simple interface designed to be accessible to beginners. The so-called "WebIDE" is installed on the Raspberry Pi and then can be run on any other networked computers from within a web browser. It syncs your programming code with Github competitor Bitbucket as well.
The Raspberry Pi WebIDE is currently in alpha and can now be downloaded by the public for those Raspberry Pi users adventurous enough to test it out. Adafruit has put together an installation guide as well as made an install script available to simplify installation. The WbIDE acts like any other programming environment in that you can add and edit files as well as test code on the Raspberry Pi hardware. Hitting "Run" on a program will open up a terminal on the Pi and execute your program, allowing you to develop your code on the hardware it will be used on. Further, it has an automatic update feature for the IDE software itself.
Because of its in-development alpha status, the current release is likely to be somewhat buggy and rough around the edges. Adafruit recommends that only experienced users install it at this time. While there is no ETA on a final release, Adafruit has stated that "it is certainly our intention to get this solid and ready for all users, and we will let everyone know when we think it is at that point."
This definitely seems like a useful piece of software if you picked up a Raspberry Pi to learn programming. You can find the full Raspberry Pi WebIDE guide in PDF form on the Adafruit website.

Dell recently announced that it is turning to an open source Linux OS to craft a developer focused operating system. Enabled by Dell’s incubation program (and accompanying monetary funding), the pilot program – named Project Sputnik – is based on Dell’s XPS13 ultrabook and the Ubuntu 12.04 LTS OS.
The Project Sputnik program will run for six months. Its goal is to create the ideal hardware and software platform for software developers. Currently, that means using Dell’s XPS13 laptop and a customized version of the Ubuntu 12.04 Linux OS. The team behind the initiative are working closely with Canonical (Ubuntu developers) to put together a custom Ubuntu image with stripped down software, custom drivers, and only the software packages that developers want.
The team wants to make it easy for software programmers to get a hold of the programing languages and environments that they need to do their jobs. It will have integration with GitHub for coding projects as well.
In the video below Barton George, Director of Marketing for Dell, talks about the Project Sputnik program and how they hope to craft a laptop aimed directly at developers.
It is an interesting program, and I hope that it does well. You can find more information about Project Sputnik and how you can get involved at the Dell website.

During this morning's keynote at the AMD Fusion Developer Summit, Microsoft's Herb Sutter went on stage to discuss the problems and solutions involved around programming and developing for multi-processing systems and heterogeneous computing systems in particular. While the problems are definitely something we have discussed before at PC Perspective, the new solution that was showcased was significant.
C++ AMP (accelerated massive parallelism) was announced as a new extension to Visual Studio and the C++ programming language to help developers take advantage of the highly parallel and heterogeneous computing environments of today and the future. The new programming model uses C++ syntax and will be available in the next version of Visual Studio with "bits of it coming later this year." Sorry, no hard release date was given when probed.
Perhaps just as significant is the fact that Microsoft announced the C++ AMP standard would be an open specification and they are going to allow other compilers to integrated support for it. Unlike C# then, C++ AMP has a chance to be a new dominant standard in the programming world as the need for parallel computing expands. While OpenCL was the only option for developers that promised to allow easy utilization of ALL computing power in a computing device, C++ AMP gives users another option with the full weight of Microsoft behind it.
To demonstrate the capability of C++ AMP Microsoft showed a rigid body simulation program that ran on multiple computers and devices from a single executable file and was able to scale in performance from 3 GLOPS on the x86 cores of Llano to 650 GFLOPS on the combined APU power and to 830 GFLOPS with a pair of discrete Radeon HD 5800 GPUs. The same executable file was run on an AMD E-series APU powered tablet and ran at 16 GFLOPS with 16,000 particles. This is the promise of heterogeneous programming languages and is the gateway necessary for consumers and business to truly take advantage of the processors that AMD (and other companies) are building today.
If you want programs other than video transcoding apps to really push the promise of heterogeneous computing, then the announcement of C++ AMP is very, very big news.
