Episode 50 of C++ Weekly.
Inheriting Lambdas vs Generic Lambdas
by Jason Turner
About the show:
The last episode of C++ Weekly showed why and where we might want to inherit from lambdas and create a merged lambda with the signatures of two or more other lambdas. In this episode Jason compares a merged lambda with a generic lambda and what the pros and cons might be.

Episode 88 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Stephan T. Lavavej to talk about Microsoft's STL and some of the changes to the Library coming in the VS 2017 release.
CppCast Episode 88: Microsoft's STL with Stephan T. Lavavej
by Rob Irving and Jason Turner
About the interviewee:
Stephan T. Lavavej is a Principal Software Engineer at Microsoft, maintaining Visual C++'s implementation of the C++ Standard Library since 2007. He also designed a couple of C++14 features: make_unique and the transparent operator functors. He likes his initials (which people can actually spell) and cats (although he doesn't own any).

A first posting about working with Qt and Visual C++ in QtCreator
Using QtCreator together with the Visual Studio Build Tools
by Jens Weller
From the article:
For a while I've been using QtCreator as my IDE, mostly because its deep integration with Qt, as most of my projects are Qt related. With this, I also preferred (and still do a little) to use the MinGW builds of Qt on Windows. In the past, as GCC was a little bit better with the newer standards, today, well, never change a running system...

Zebedee Mason discusses in his recent article some GOF idioms and analyzes them with his tool DeepsEnds.
Dependencies in the Gang of Four examples
by Zebedee Mason
From the article:
The example C++ code from the GoF (Gang of Four) book Design Patterns has had its dependencies analysed with DeepEnds. Certain examples have been refactored to remove circular dependencies enabled by pre-declaration of classes. These cycles in the graph serve to reduce the ability to subsequently modify the code with ease.

Fold Expressions
by Rainer Grimm
From the article:
With fold expressions you can implement the from Haskell known functions

Using futures with callbacks.
Wrapping Callbacks with Futures
by Anthony Williams
From the article:
Libraries the perform time-consuming operations, or network-based operations, often provide a means of running the task asynchronously, so that your code can continue with other things while this operation is performed in the background...

Giuseppe D'Angelo explains how the Qt project deprecates APIs, a challenge every library project faces.
Un-Deprecate Your Qt Project
by Giuseppe D'Angelo
From the article:
Any product needs to evolve if it wants to remain competitive. If the development bandwidth is finite, from time to time there is the need to drop some ballast. This does not necessarily mean dropping working functionality and leaving users in the cold. At least in Qt most of the time this actually means replacing working functionality with better working functionality.
This process has being going on in Qt since forever, but since Qt 5.0 we’ve started to formalize it in terms of documentation hints and macros in the source code. This was done with a precise purpose: we wanted Qt users to discover if they were using deprecated APIs, and if so, let them know what better alternatives were available.
And since the very release of Qt 5.0.0 we’ve officially deprecated hundreds of APIs: a quick grep in QtBase alone reveals over 230 hits (mostly functions, but also entire classes).
