Interactive Metaprogramming Shell based on Clang
by Ábel Sinkovics
From the talk description:
Developing metaprograms is hard and painful. Templight (http://plc.inf.elte.hu/templight/) supports the development and debugging of template metaprograms, but the code has to be recompiled after every minor change and tricks are needed to retrieve useful information about the result...

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:
Data-Oriented Design and C++
by Mike Acton
Summary of the talk:
The transformation of data is the only purpose of any program. Common approaches in C++ which are antithetical to this goal will be presented in the context of a performance-critical domain (console game development). Additionally, limitations inherent in any C++ compiler and how that affects the practical use of the language when transforming that data will be demonstrated.

Expression Templates Revisited
by Klaus Iglberger
From the talk description:
Since their invention in 1995, Expression Templates (ETs) have proven to be a valuable tool for many C++ template libraries. Especially numerics libraries quickly embraced them as salvation for the performance deficiencies of standard C++. This reputation as performance optimization...

C++ SIMD parallelism with Intel Cilk Plus and OpenMP 4.0
by Georg Zitzlsberger
From the talk description:
Performance is one of the most important aspects that comes to mind if deciding for a programming language. Utilizing performance of modern processors is not as straight forward as it has been decades ago. Modern processors only rarely improve serial execution of applications by increasing their frequency or adding more execution units.

Implementing Wire Protocols with Boost Fusion
by Thomas Rodgers
(watch on YouTube) (watch on Channel 9)
Summary of the talk:
There are a number of common serialization formats available which work well for marshaling C++ types into messaging protocols, e.g. ProtoBufs, Thrift, JSON, XML, FIX, etc. Unfortunately, not every protocol uses one of these popular encodings and instead implements a unique binary protocol. The classical "C" way of handling binary protocols is to use packed structs, unfortunately there are many binary protocols which are not particularly friendly to using this approach due to things like nested variable length data structures, etc.. The packed struct approach is also fairly limited in that it only generally supports primitive POD types.
This talk will explore an approach that uses Boost's Fusion library to implement an easily extensible serialization mechanism for on a non-trivial binary financial exchange protocol which exposes the underlying data in terms of "modern" C++ types. The talk will also cover aspects of general use of Boost Fusion and Boost MPL, type traits, enable_if, SFINAE, and other members of the C++ type system bestiary.

The Canonical Class
by Michael Caisse
Summary of the talk:
It was a simpler time. A period in which every college student and learn-C++-in-a-weekend duffer could write a class with the assuredness that it would behave as desired when assigned and copied. There was a check list. Complete the checklist, add some domain specific behaviour, bake in the regression oven, and you were done.
Enter C++11 with its fancy new use of the delete keyword, additional applications of explicit, rvalue references, and some perfect forwarding. How are you to write a "simple" class? Should you include a swap? What does movable mean and are there expected semantics? When is the noexcept specifier used?
During this session we will explore the boilerplate of a C++11 class. The session will touch on rvalue references, move semantics, perfect forwarding, explicit, noexcept, initializer lists, and more as it applies to producing the desired semantics for our classes and structs.

Generic parallel programming for scientific and technical applications
by Guntram Berti
From the talk description:
Technical and scientific applications dealing with a high computational load today face the challenge to match the increasingly parallel nature of current and future hardware. The talk shows how the increased complexity of software can be controlled by using generic programming technologies. The process and its advantages are introduced using many concrete examples...

Testdriven C++ with Catch
by Phil Nash
From the talk description:
C++ has been notorious for being a second class citizen when it comes to test frameworks. There are plenty of them but they tend to be fiddly to set-up and ceremonious to use. Many of them attempt to follow the xUnit template without respect for the language environment they are written for. Catch is an attempt to cut through all of that...

C++11 library components to make a programming scientist happy
by Peter Gottschling
From the talk description:
This talk presents a survey over components of the C++11
standard library which facilitate the life of a programming scientist.
It will provide a gentle introduction to the random number generator
and evolve this to a complete application: the stochastic simulation
of share price development.

The C++ Memory Model

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++...
