Share what you've learned about C++.
Call for Submissions
by CppCon
From the announcement:
Have you learned something interesting about C++, maybe a new technique possible in C++14/17? Or perhaps you have implemented something cool related to C++, maybe a new C++ library? If so, consider sharing it with other C++ enthusiasts by giving a regular program talk at CppCon 2017.
The submissions deadline is June 11 with decisions sent by July 12.

Jakie Kay explores in her recent blog post the borders of nearly unknown C++ features:
Fun with Reflection in C++
by Jakie Kay
From the article:
In my previous post, we learned about the current and future state of reflection in C++. But I left a few questions unanswered. Indeed, you may still be wondering why I care so much about reflection and if it has any useful applications for the average programmer. In this post, I’ll try to answer that question with real code examples using the two reference implementations of C++ reflection. I’ll explore the strengths of the two implementations, as well as the major limitations. These examples make heavy use of metaprogramming and C++17 features, so if you find yourself in unfamiliar territory while reading the code, I suggest supplementing this article with other resources.
When I refer to the reflexpr implementation, I’m talking about Matúš Chochlík’s fork of Clang which implements P1094, by Chochlík, Axel Naumann, and David Sankel.
When I refer to cpp3k, I’m talking about Andrew Sutton’s fork of Clang which implements P0590R0, by Sutton and Herb Sutter.

Episode 100 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Bjarne Stroustrup, designer and original implementer of C++ to discuss the current state of C++, his vision for the future as well as some discussion of the past.
CppCast Episode 100: Past, Present and Future of C++ with Bjarne Stroustrup
by Rob Irving and Jason Turner
About the interviewee:
Bjarne Stroustrup is the designer and original implementer of C++ as well as the author of The C++ Programming Language (Fourth Edition) and A Tour of C++, Programming: Principles and Practice using C++ (Second Edition), and many popular and academic publications. Dr. Stroustrup is a Managing Director in the technology division of Morgan Stanley in New York City as well as a visiting professor at Columbia University. He is a member of the US National Academy of Engineering, and an IEEE, ACM, and CHM fellow. His research interests include distributed systems, design, programming techniques, software development tools, and programming languages. To make C++ a stable and up-to-date base for real-world software development, he has been a leading figure with the ISO C++ standards effort for more than 25 years. He holds a master’s in Mathematics from Aarhus University and a PhD in Computer Science from Cambridge University, where he is an honorary fellow of Churchill College.

Quick A: They behave differently, it depends on what you need.
Recently on SO:
When should you ever use functions over functors in C++?
Functions support distributed overriding. Functors do not. You must define all of the overloads of a Functor within itself; you can add new overloads of a function anywhere.
Functions support ADL (argument dependent lookup), permitting overloading in the argument-type associated namespace. Functors do not.
Function pointers are a kind of type-erased stateless functor that is a POD, as evidenced by how stateless lambdas convert into it. Such features (POD, stateless, type erasure) are useful.

An interesting article as well as a nice demo!
A true heterogeneous container in C++
by Andy G
From the article:
Oftentimes I see questions StackOverflow asking something to the effect of
“Can I have a std::vector that holds more than one type?”
The canonical, final, never-going-to-change answer to this question is a thorough“No”
C++ is a statically-typed language. A vector will hold an object of a single type, and only a single type.“But…”
Of course there are ways to work around this...
