In C++11, std::tuple was introduced. What is it good for? Why would you use it? Isn't it just a simple generalization of std::pair? Come and see why not, and what you can do with tuples!

This talk is about the “Whys” and “Hows” of the DDS-PSM-Cxx standard. The DDS-PSM-Cxx standard is among the family of standards around the core Data Distribution Service (DDS) standard for developing high-performance distributed real-time systems. DDS-PSM-Cxx provides a portable C++ API for programming DDS, which is modern, idiomatic, STL-friendly, expressive, safe, and efficient. DDS-PSM-Cxx targets C++03 but makes special provisions for ensuring forward portability in C++11 environment. The presentation will first describe what DDS is and why it matters. The objectives and the high-level structure of the DDS-PSM-Cxx standard will be described next along with a “Hello, World!” example. The talk will further describe interesting aspects of the standard, such as the support for drop-in replacement of conforming vendor implementations, syntactic cues for vendor-specific API extensions, and the use of various C++03 idioms to provide a clean, safe, and efficient API. We will discuss exception-safety considerations that shaped the standard in important ways. Finally, we will discuss the special rules that allow conforming C++03 applications be forward compatible in C++11 environment.
