CppCast Episode 6: Fit and Tick with Paul Fultz II

by Rob Irving

Paul Fultz II has developed in C++ professionally and personally in a variety of fields including DSP, web development, and desktop applications. He has developed in other languages as well such as Java, C#, Python, and Javascript but focuses most of his attention on C++ which combines correctness, expressiveness, and performance together.

Adventures In Updating A Legacy Codebase

by Billy Baker

(watch on YouTube) (watch on Channel 9)

Still maintaining a legacy application? Do you have strdup()'s crying to be replaced with std::string? Do pre-standard headers such as iostream.h litter your code? Do boost libraries no longer compile with your favorite C++98 compiler? From GUIs to kernel drivers, this talk will look at some of the adventures taken while updating a codebase with more than 20 years of history to C++11.

Viewing The World Through Array-Shaped Glasses

by Łukasz Mendakiewicz

(watch on YouTube) (watch on Channel 9)

It's agreed among experts that the most performant data structure in C++ is an array. Or a vector. Or a dynarray. Indeed, until recently there was no standardized approach in C++ to view these types in an uniform manner. It was even murkier when the data had logically more than one dimension. This talk is an introduction to the new features proposed for C++17 in N3851 [TBD: update after Rapperswil] bringing all contiguous data into harmony and lifting it to higher dimensions: index, bounds, array_view and more. Attendees will also learn how indexable algorithms differ from the traditional elemental ones, and what does it mean for parallelism.

An Overview of C++11/14, Part II

by Leor Zolman

(watch on YouTube) (watch on Channel 9)

This accelerated introduction to C++11/14 surveys most of the key additions to the C++ language, including support for increased code clarity (lambdas, uniform initialization, auto, new OOD control) and improved performance (rvalue references, move semantics and perfect forwarding.)

The presentation is designed for those who truly need a quick overview of the new C++, so the focus is on breadth rather than depth. Whenever feasible, new language features are presented in a style showcasing how they improve over their "Old C++" counterparts.

CppCast Episode 5: Exploring CLion with Anastasia Kazakova

by Rob Irving

Being a C/C++ fan since University Anastasia has been creating real-time *nix-based systems and pushing them to production for 8 years. She has a passion for networking algorithms (especially congestion problems and network management protocols) and embedded programming, and believes in good tooling. Now she is a part of the JetBrains team working as a Product Marketing Manager for CLion the upcoming cross-platform C/C++ IDE.

Generic Programming with Concepts Lite, Part II

by Andrew Sutton

(watch on YouTube) (watch on Channel 9)

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.

Metaprogramming with Boost.Hana: Unifying Boost.Fusion and Boost.MPL

by Louis Dionne

(watch on YouTube) (watch on Channel 9)

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).
