Casablanca: C++ on Azure -- John Azariah and Mahesh Krishnan

By Blog Staff | Sep 19, 2012 02:55 PM | Tags: None

Casablanca is a Microsoft incubation effort to support cloud-based client-server communication in native code using a modern asynchronous C++ API design. Think of it as Node.js, but using C++ -- from simple services, to JSON and REST, to Azure storage and deployment, and more.

Casablanca gives you the power to use existing native C++ libraries and code to do awesome things on the cloud server. In this talk from TechEd Australia, John Azariah and Mahesh Krishnan show how it's done.

ASIO: Portable Stackless Coroutines in One* Header -- Chris Kohlhoff

By Blog Staff | Sep 17, 2012 09:01 AM | Tags: advanced

Via C++ Next, hat tip to Dave Abrahams:

Chris Kohlhoff’s ASIO library contains an extraordinary little header, not in the public interface, but in the examples directory, that implements what he calls “Stackless Coroutines” (very similar to Python’s Simple Generators if you’re familiar with those). He does it completely portably, with just a few macros, and considering that there are zero lines of platform-specific code, they work amazingly well.

Dave cites this article that describes how to use the coroutines:

A potted guide to stackless coroutines

Keen-eyed Asio users may have noticed that Boost 1.42 includes a new example, HTTP Server 4, that shows how to use stackless coroutines in conjunction with asynchronous operations. This follows on from the coroutines I explored in the previous three posts, but with a few improvements. In particular:

• the pesky entry pseudo-keyword is gone; and
• a new fork pseudo-keyword has been added.

The result bears a passing resemblance to C#'s yield and friends. This post aims to document my stackless coroutine API, but before launching into a long and wordy explanation, here's a little picture to liven things up...

VC++ 2012 Desktop Express (free)

By Blog Staff | Sep 12, 2012 11:42 AM | Tags: None

Today Microsoft released another free Express version of Visual C++ 2012. In addition to the free Express Visual C++ compiler for building tablet applications, Visual Studio Express 2012 for Windows Desktop directly supports traditional Windows and command-line applications in C++.

This a great free C++ compiler on Windows for everything from hobby development to using and contributing to open source projects. Besides additional C++11 standards conformance with range-for, override and final on the language side (with more to come in the coming months; watch this space) and a complete C++11 standard library implementation, the free compiler also includes unit testing framework for C++, code analysis for C++ (try /analyze today if you haven't already, as John Carmack says so well), C++ AMP for GPGPU programming, and much more.
