Do you know that keyword?
Mutable
by Arne Mertz
From the article:
The
mutablekeyword seems to be one of the less known corners of C++. Yet it can be very useful, or even unavoidable if you want to write const-correct code or lambdas that change their state...

Quick A: To hide implementation details
Recently on SO:
Why would one use nested classes in C++?
Nested classes are cool for hiding implementation details
List:
class List { public: List(): head(NULL), tail(NULL) {} private: class Node { public: int data; Node* next; Node* prev; }; private: Node* head; Node* tail; };Here I don't want to expose Node as other people may decide to use the class and that would hinder me from updating my class as anything exposed is part of the public API and must be maintained forever. By making the class private, I not only hide the implementation I am also saying this is mine and I may change it at any time so you can not use it.
Look at std::list or std::map they all contain hidden classes (or do they?). The point is they may or may not, but because the implementation is private and hidden the builders of the STL were able to update the code without affecting how you used the code, or leaving a lot of old baggage laying around the STL because they need to maintain backwards compatibility with some fool who decided they wanted to use the Node class that was hidden inside <list>.

A follow up on error codes.
error codes — some clarifications
by Andrzej Krzemieński
From the article:
In this post I would like to discuss two issues brought up by the readers regarding previous posts on using <system_error>:
- Storing 0 in error codes, and using non-0 success values.
- Concerns about using globals.

Summary of the articles about C++17, with additional bonus
C++17 in detail: Summary & Bonus
by Bartlomiej Filipek
From the article:
It was a great jurney, 8 articles where we covered most of the new stuff in C++17. As a bonus I merged all of the content into one PDF. That way it might be easier to read. Have a look.

CppCon 2017 Trip Report
by Isabella Muerte
From the article:
It's been a few days since I got back from CppCon 2017. As a millenial, I easily cave to peer pressure and because everybody else is doing it, I figured I might as well write a trip report too.

My CppCon 2017 Trip Report – 10 great talks to watch and learn from
by Quentin Duval
From the article:
The last edition of the CppCon 2017 just ended. As for the previous edition, it was a real pleasure to be there, discussing with talented and curious fellow developers, and watching great talks. In particular, I got the feel that the conference offered more diverse talks than the previous edition...
