How do you do it?
Destructing outside the lock when removing items from C++ standard containers
by Raymond Chen
From the article:
Last time, we saw that object destruction is a hidden callout that can cause you to violate the rule against calling out to external code while holding an internal lock...

Quick: in order to make x a dependent name, so that lookup is deferred until the template parameter is known
Recently on SO:
Why do I have to access template base class members through the this pointer?
If the classes below were not templates I could simply have x in the derived class. However, with the code below, I have to use this->x. Why?
template <typename T> class base { protected: int x; }; template <typename T> class derived : public base<T> { public: int f() { return this->x; } }; int main() { derived<int> d; d.f(); return 0; }

Taking a look at next weeks keynote by Teresa Johnson
Teresa Johnsons Center Keynote: ThinLTO Whole Program Optimization: Past, Present and Future
by Jens Weller
From the article:
Whole program optimization enables higher performance in C++ applications, because of the expanded scope for analysis and optimization. Traditionally, whole program optimization is not scalable in memory or time, and doesn't support effective incremental builds. ThinLTO (Thin Link Time Optimization) is a new compilation model that...

Jonathan Boccaras Meeting C++ 2020 opening keynote: meta-polymorphism
by Jens Weller
From the article:
When you hear polymorphism you may think virtual functions, but this is just one speck of dust in the polymorphism universe.

The book "C++ Move Semantics - The Complete Guide" is now done and out as ebook or printed.
C++ Move Semantics - The Complete Guide
by Nicolai Josuttis
About the book
On 260 pages (yes, it is that complicated if you want to deal with all the details), Nicolai Josuttis introduces and explains all aspects of C++ move semantics:
- Intuitive motivation
- Compelling examples
- Tricky details
The book covers all aspects of move semantics:
- From std::move() and rvalue references
- Over reference qualifiers, invalid moved-from states, and value categories
- Up to tricky details in generic code using std::forward(), universal/forwarding references, auto&&, and decltype(auto).
Additional chapters about move-only types and the support of move semantics in the C++ standard library help to understand and use standard types in practice.
See cppmove.com for a detailed list of all topics covered.

During CppCon I noticed how well AMA sessions went and that they are a great feature for an online conference. And for some time I knew that this years conference has some extra space for content due to its online nature.

The new book by Nico Josuttis is now available as an ebook draft.
C++ Move Semantics - The Complete Guide
by Nico Josuttis
About the book:
Having 200 pages, the description of move semantics is feature complete now. Only a few chapters about the use of move semantics in the C++ standard library are missing.
The book teaches all aspects of C++ move semantics. Starting from the basic principles it motivates and explains all features and corner cases (such as perfect returning with
decltype(auto)) so that a C++ programmer can understand and use move semantics right in application code, when implementing classes, in generic code, and in foundation libraries.
