P1169 “static operator()”
(Barry Revzin and Casey Carter, August 2021) proposes that we should be able to define
operator() as a static member function. This is a very good idea.
As of this writing, it also looks likely to get into C++2b. So instead of e.g.

While learning how to use the new C++ Standard, I encountered several intriguing cases with smart pointers. Casting? Array handling? Passing to functions?
Let’s review some common concerns so that we don’t shoot yourself in the foot :)
I created this post back in 2013, and I updated it in 2014 and recently in 2021.

Самый долгожданный выпуск про C++ уже на канале! В гостях Lead Core Developer World of Tanks Blitz из компании Wargaming- Леонид Чайка.
Мы проговорили без малого три часа, и вам есть что почерпнуть из этого интервью: история становления обычного парня, который не хватал звезд с неба; детальный разбор языка c++ и сфер его применения; разработка игр от 2D-Марио до Triple-A "World of Tanks"! И это далеко не все затронутые темы 😊
Так что, заваривайте чаинский/кофеинский - будет интересно 😉

One of the biggest new features of C++20 are concepts. Concepts define requirements on template arguments which are enforced by the compiler. This leads to more readable code which clearly expresses intent. Error messages are improved since violations of the constraints defined by concepts can be detected in the early stages of the template instantiation.
This talked is aimed at people with little or no experience with concepts and will introduce generic programming with concepts (constraining templates, writing your own concepts and overloading functions which are constrained by concepts)

I probably could have generated more clicks by titling this “How I Improved std::unordered_map Performance By 50x With This Little Trick”. In reality, this post is mostly about my journey crafting the following snippet that allows you to measure the quality of your hash function on a concrete std::unordered_map: template

Modern C (2019)

This blog post describes the optimizations enabled by -ffast-math when
compiling C or C++ code with GCC 11 for x86_64 Linux (other languages/operating
systems/CPU architectures may enable slightly different optimizations).

In my C++ training classes, I often explain the meaning of =delete as


 The library author is saying, “I know what you’re trying to do,
and what you’re trying to do is wrong.”
