Constexpr all the things.
constexpr Dynamic Memory Allocation, C++20
by Bartlomiej Filipek
From the article:
constexpr has become a major feature for compile-time programming in C++. Introduced in a simple form in C++11 evolved into almost another “sub-language”, an alternative to regular template code. In C++20 you can even use std::vector and std::string in constexpr context!
In this article, I’d like to discuss constexpr memory allocations, a building block for std::vector. Let’s see how this feature works and see its limitations...

New video on the CopperSpice YouTube Channel:
Mutex + Lock = CsLibGuarded
by Barbara Geller and Ansel Sermersheim
About the video:
Our newest C++ video looks at a better way to lock a mutex. We look at making the data part of the solution. The video walks through several variations of an example to explain why the data, mutex, and lock should be tied together and the benefits that result from this change.

Introduction to OpenCV with VcPkg and CMake
by Richard Thomson
From the video description:
OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.
This month, Richard Thomson will give us an introduction to OpenCV and walk us through some examples of using the library. OpenCV is a large library, so not every detail can be presented at once. However, we'll try to get a feel for what it looks like to use components from the library and perform some simple image manipulation tasks.

Should we use almost always auto parameters?
Don't automatically use auto parameters in C++
by Lesley Lai
From the article:
Since C++14, we can create lambda expressions that take auto parameters. C++20 generalizes this idea by allowing us to do the same thing for regular functions. With this feature's advent, the programming style where all parameters are auto becomes popular among some C++ programmers. However, I think we should not use it if we had to. The more specific the type of the parameter is, the better.
