This year using std::cpp includes the following talks:

  • C++17 is (almost) here. J. Daniel García (ARCOS Lab, University Carlos III), member of ISO C++ standards committee and associate professor in Computer Architecture.
  • Get your types to work. Software developer and contributor of several Boost libraries (example, Boost multi-index).
  • C++ and much more. An overview to the available libraries univers. Martin Knoblauch (Indizen Technologies), a software developer in the finance sector.
  • Test Driven Development in C++. Raúl Huertas (TCP Sistemas), a software developer with long background in the telecom business.
  • Using C++ in safety critical embedded systems for railways. Ion Gaztañaga (CAF), another Boost contributor (example, Boost Interprocess).
  • At a Matlab breakdown... Save me C++! Javier Garcia-Blas (ARCOS Lab, University Carlos III), visiting professor in Computer Architecture.
  • Static and dynamic polymorphism in C++11: Flexibility versus performance?. J. Daniel Garcia (ARCOS Lab, University Carlos III), member of ISO C++ standards committee and associate professor in Computer Architecture.
  • Using templates in C++ to design and implement. Jose Caicoya (Hotel Beds), software developer with background in real-time systems, finance and, more recently, hotel reservation systems.
  • Distributed systems: How to connect your real-time applications. Jaime Martin (eProsima), developer of an open source DDS impelementation.
  • Developing an reflection system for C++14. Manu Sanchez (ByTech), software developer and metaprogrammer.

About using std::cpp

The using std::cpp event has been happening every year since 2013 in University Carlos III (Leganes, Madrid, Spain), where every year around 200 developers have gathered to share experiences in using C++ for professional software develpment.

The event is organized by ARCOS Lab (University Carlos III), a research group focused in applications of high performance computing to multiple domains. It is also sponsored by Indizen Technologies.

Visiting variants using lambdas (1) - - Vittorio Romeo

By Vittorio Romeo | Oct 19, 2016 05:11 AM | Tags: c++17

The article covers a technique that allows variant types (both `std::variant` and `boost::variant`) to be visited using lambdas, without having to explicitly create a functor.

visiting variants using lambdas - part 1

By Vittorio Romeo

From the article:

Visiting a variant is usually done by writing a visitor struct/class outside of the scope where the variant is actually being visited. [...] It is possible to build such an object locally in the call site [...] by implementing something similar to `std::overload`.

Are you clear with unsigned?

The “unsigned” Conundrum

by Tony “Bulldozer00” DaSilva

From the article:

A few weeks ago, CppCon16 conference organizer Jon Kalb gave a great little lightning talk titled “unsigned: A Guideline For Better Code“. Right up front, he asked the audience what they thought this code would print out to the standard console:

Even though -1 is obviously less 1, the program prints out “a is not less than b“. WTF?

Following the core guidelines is becoming easier.

C++ Core Check code analysis is included with VS “15”

by Andrew Pardoe

From the article:

Visual Studio “15” Preview 5 now includes the C++ Core Guidelines Checkers. This means you no longer have to install the C++ Core Check package from NuGet to check your code against rules and profiles in the C++ Core Guidelines. Just configure Code Analysis to include the C++ Core Check extensions.
