Small thing to make life better.
Various Template Improvements with C++20
by Rainer Grimm
From the article:
Admittedly, I present in this post a few small improvements to templates and to C++20 in general. Although these improvements may seem not so impressive to you, they make C++20 more consistent and, therefore, less error-prone when you program generic.

An interesting read.
Thirty Years C++. Interview with Bjarne Stroustrup
by Roberto V. Zicari
From the article:
“If you keep your good ideas to yourself, they are useless; you could just as well have been doing crossword puzzles. Only by articulating your ideas and making them accessible through writing and talks do they become a contribution.” –Bjarne Stroustrup
Back in 2007 I had the pleasure to interview Bjarne Stroustrup, the inventor of C++ programming language. Thirteen years later…, I still have the pleasure to publish an interview with Bjarne...

Motivation behind reference_wrapper and common use cases.
std::ref and std::reference_wrapper: Common use cases
by Hitesh Kumar
From this article:
An std::reference_wrapper is a copyable and assignable object that emulates a reference. Contrary to its name, it does not wrap a reference. It works by encapsulating a pointer (T*) and by implicitly converting to a reference (T&). It cannot be default constructed or initialized with a temporary; therefore, it cannot be null or invalid.

A few days ago, one particularly ambitious victim student of mine asked for assistance in tracking down a bug.
A plea for order
by Philipp Lenk
From the article:
I know I promised to talk more about emulation, about chess and operating systems, but I have to get something off of my chest first. This is not going to be one of my would-be grand and elongated epics trying to cover far too much in far too many words. Instead, I shall focus on one very small, very self contained thing: the order of #include directives in C++ source code

Quick A: there is no guarantee for a container to work with incomplete types.
Recently on SO:
Recursive unordered_map
STL containers are not required to work with incomplete types. If you don't mind extra indirection, then the workaround is
std::map<int, std::unique_ptr<Node>>.
