Providing Explicit Specializations for Non-Template Members of Class Template -- Pavel Frolov

By psfrolov | Jan 19, 2015 10:10 AM | Tags: advanced

One of the lesser-known features of C++ templates.

Providing Explicit Specializations for Non-Template Members of Class Template

by Pavel Frolov

From the article:

C++ is full of surprises (albeit not always good ones grin. It is a well known fact that you can provide explicit specializations for function templates and class templates. But it was a total surprise to me, that you can provide explicit specializations for non-template members of class template without specializing the class template itself!

The C++ Memory Model - Valentin Ziegler @ Meeting C++ 2014

A new video from Meeting C++ 2014:

The C++ Memory Model

by Valentin Ziegler

From the talk description:

The C++ memory model defines how multiple threads interact with memory and shared data, enabling developers to reason about concurrent code in a platform independent way. The talk will explain multi-threaded executions and data races in C++...

Pruning Error Messages From C++ Template Code

by Roland Bock

From the talk description:

Many template libraries are regarded with ambivalent feelings by developers: On the one hand, such libraries can offer wonderful functionality. On the other hand, they are dreaded for the sheer amount of error messages spilled out...

A solution to generate code for CUDA and OpenCL with C++:

Generating OpenCL/CUDA source code from C++ expressions in VexCL

by Denis Demidov

From the talk description:

VexCL is an opensource C++ vector expression template library for OpenCL/CUDA. It has been created for ease of GPGPU development with C++ and provides convenient and intuitive notation for linear algebra operations, vector arithmetic and various parallel primitives.

Multiplatform C++ - Edouard Alligand @ Meeting C++ 2014

The latest version of Edouard Alligands talk on Multiplatform development with C++:

Multiplattform C++

by Edouard Alligand

From the talk description:

C++ is a multiplatform language, yet many difficulties arise when you want the same code to compile properly and function identically on different platforms. If you put aside the obvious system programming related obstacles, and the differences you might have between compilers (especially when it comes to supporting C++11 and C++14), you come to the surprising conclusion that what is truly hard is all the “little things” you didn’t anticipate.

Ivan Cukic gave a very good talk on monads at Meeting C++ 2014:

Monads in Chains

by Ivan Cukic

From the talk description:

Monads are scary, and monads are evil. But they are still useful.

In the recent years, the abuse of multi-threading has become apparent and more and more systems started being developed in the reactive, or event-processing style. It allows lowering the number of threads to match the system cores instead of items that are being processed by using non-blocking asynchronous APIs.

Tutorial on Tag Dispatching -- Crazy Eddie

Fresh on Crazy Eddie's Crazy C++ (fortunately not entirely true...):

Tutorial on tag dispatching

by Crazy Eddie

From the article:

... There’s been some confused notions passed around recently that lead me to think there needs to be more information about probably one of the simplest, most powerful metaprogramming techniques that exist in C++: tag dispatching. The reason tag dispatching is powerful is that it leverages the language and the compiler to do work for you so that you don’t have to. It’s a technique whereby you use overload resolution rules to decide between otherwise ambiguous functions.

Concepts and tags

The first part to understand with regard to tag dispatching is the idea of “concepts”...
