Another explanation why const is a really powerful tool.
Please declare your variables as const
by Bartlomiej Filipek
From the article:
When using const the resulting code will be more verbose, explicit, cleaner (with probably smaller functions) and safer. Not to mention that you’ll get additional help from the compiler.

A good question with a good answer.
When noexcept?
by Edouard of quasardb
From the article:
In a previous post, we had a look at the new constexpr keyword that has been introduced in C++ 11. Today we'll study another new fancy specifier: noexcept...

Episode 41 of C++ Weekly.
C++17's constexpr Lambda Support
by Jason Turner
About the show:
In this episode Jason demonstrates how C++17's support for lambdas in a constexpr context can clean up many constexpr use cases.

The new if constexpr will change a good part of our code for the better!
Simplifying templates and #ifdefs with if constexpr
by Simon Brand
From the article:
if constexpris a C++17 feature which allows conditionally compiling code based on template parameters in a clear and minimal fashion. It is essentially an if statement where the branch is chosen at compile-time, and any not-taken branches are discarded without being instantiated...

Does [x = std::forward<decltype(x)>] behave like you expect?
capturing perfectly-forwarded objects in lambdas
by Vittorio Romeo
From the article:
Perfect forwarding and forwarding references allow developers to write generic template functions that retain the lvalueness/rvalueness of passed arguments [...] Let's try to use auto&&, std::forward and C++14's generalized lambda capture syntax to implement our desired semantics. [...] What we really want to do is:
- Capture by copy if a is an rvalue reference.
- Capture by reference if a is an lvalue reference.
[...]

More interesting facts about captureless lambdas.
Technical Debt
by Adi Shavit
From the article:
The series on captureless lambdas generated some interesting comments.
The articles discusses converting captureless lambdas into function pointers without explicitly specifying the cast-to type, calling conventions and standard conformance and a special callbackizing function for capturing lambdas.

Hi all, I have been on airplanes for the last 10 weeks in a row, starting with CPPCON 2016 on September 16 2016. But first, I wanted to update everyone on the latest status of the C++ Standard meeting from Issaquah on Nov 7, 2016. Here is a blog post where you can see a video of what is coming for C++17 and download the slides. You can also see what happened in Issaquah for Evolution, Parallelism, Concurrency, and the latest status of the National Body Comments:
