While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:
Generic Programming with Concepts Lite, Part II
by Andrew Sutton
Summary of the talk:
In this talk, I will give an overview of the Concepts Lite language extension for C++ and present examples of its use in design and implementation of real-world generic libraries. Concepts Lite provides the ability for programmers to directly state constraints on template arguments as part of the template declaration. These constraints are predicates which determine whether or not a template argument can be used with that template. Constraints are checked by the compiler at the point of use, meaning that that effectively constrained generic libraries will not suffer from the usual problems of insane diagnostics. Libraries written using concepts will be far more readable and maintainable than the status quo. This talk will focus on generic programming, proposed language features, and their use in building real-world libraries.
Concepts Lite is a forthcoming ISO Technical Specification (TS) aimed at publication alongside C++14. Concepts Lite is implemented in a branch of GCC, which will be made available to the audience for experiments and experience.

The STE||AR Group has released V0.9.10 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.
HPX V0.9.10 Released
The newest version of HPX (V0.9.10) is now available for download! Please see here for the release notes.
HPX now exposes an API fully conforming to the concurrency related parts of the C++11 and C++14 standards, extended and applied to distributed computing.

PL22.16/WG21 draft agenda: 4-9 May 2015, Lenexa KS/US
by Clark Nelson
Excerpt:
At this meeting we will address ballot comments on the Transactional Memory PDTS (N4302), and discuss whatever comments are available on the Concepts PDTS (N4377). We also aim to bring several projects to their next ballot stage, potentially including the following:

Metaprogramming with Boost.Hana: Unifying Boost.Fusion and Boost.MPL
by Louis Dionne
Summary of the talk:
Template metaprogramming sucks. No, seriously; you might like the imposed purely functional paradigm, but not the templates themselves. While C++11 has made our life easier, even simple metaprograms are often hard to write, impossible to maintain and slow to compile; we need better abstractions. In this talk, I will present Boost.Hana[1], an experimental C++14 library for heterogeneous computation. The library takes metaprogramming to a whole new level of expressiveness by unifying the well-known Boost.MPL and Boost.Fusion libraries under a single generic, purely functional interface. The library incorporates some of the most recent advances in C++ metaprogramming; I will give an overview of the most interesting implementation techniques used internally. Finally, I will show concrete ways to use the library so you, as a developer, can write less template black magic, increase your productivity and spend less time in coffee breaks waiting for the compiler (sorry).

Episode 4 of CppCast, the only podcast by C++ developers for C++ developers. In this episode David Sankel joins Rob Irving to talk about his upcoming C++Now! talk where he will be discussing the use of Cmake and Git in large C++ projects. We also touch on David's expertise with functional programming.

From a totally unnecessary blog (we beg to differ):
Range comprehensions with C++ lazy generators
by Paolo Severini
From the article:
Lazy evaluation is a powerful tool and a pillar of functional programming; it gives the ability to construct potentially infinite data structures, and increases the performance by avoiding needless calculations ...
... Functional languages like Haskell have the concept of list comprehensions ... In C#, of course, we have LINQ ... It would be nice to have something similar in an eager language like C++ ... now the lazy, resumable generators proposed by N4286 seem perfect for this purpose ... We can use the VS2015 CTP prototype to experiment with this idea ...

Quick Game Development with C++11 / C++14
by Vittorio Romeo
Summary of the talk:
Modern C++ has made game development a much more pleasurable experience. Features such as smart pointers and variadic templates are invaluable in speeding up the development process and in making the code cleaner and more robust. New easy-to-use multimedia libraries such as SFML, SDL and Cinder make dealing with graphics, sounds and input very easy, and work well with modern code principles. This talk guides the audience through the creation of an Arkanoid/Breakout clone in under 200 lines of code, using C++11/C++14 features and idioms. Chronologically sequential code segments, compiled and executed one by one, will show the attendees how a game is created from scratch, slowly becoming a playable product, step by step. The end result will be a small game, completely written in modern C++ code. Topics covered will range from basic graphics programming to entity management and collision detection/response.

Max Khiszinsky describes in his recent blog article different approaches to develop concurrent containers.
Lock-Free Data Structures. The Evolution of a Stack
by Max Khiszinsky
From the article
Describing the known algorithms would be quite boring, as there would be a lot of [pseudo-]code, plenty of details that are important but quite specific. After all, you can always find them in the references I provide in articles. What I wanted was to tell you an interesting story about exciting things. I wanted to show the development of approaches to designing concurrent containers.
