C99 library support in Visual Studio 2013
Hello, I’m Pat Brenner, a developer on the Visual C++ Libraries team. In this blog post I want to share some information about the C99 support added to the C run-time library in Visual Studio 2013. To summarize, we added declarations and implementations for missing functions in the following headers: math.h, ctype.h, wctype.h, stdio.h, stdlib.h, and wchar.h. We also added the new headers complex.h

Or, A Heterogeneous Supercomputer in Every Pocket In the twilight of Moore’s Law, the transitions to multicore processors, GPU computing, and HaaS cloud computing are not separate trends, but aspects of a single trend – mainstream computers from desktops to ‘smartphones’ are being permanently transformed into heterogeneous supercomputer clusters. Henceforth, a single compute-intensive application
