C++ moves for people who don’t know or care what rvalues are--Topher Winward

Is it simpler that way?

C++ moves for people who don’t know or care what rvalues are

by Topher Winward

From the article:

When I was first learning about move semantics in C++, I kept reading articles that explained in terms of other scary sounding jargon — lvalues, rvalue references, memcpy, ownership. None of these things are strictly necessary to know about to understand the core of move semantics. (Though, the more you learn about them, the greater your understanding of move semantics will become.)

You may have heard of move semantics, and may know that they’re “faster”, but not why, or even how to move something. (Here “moves” and “move semantics” mean the same thing.)

This article will deliberately simplify or ignore some concepts (like constructors, rvalue references, stack vs heap) to make the core idea of moving easier to follow, so don’t worry if you already know this stuff and see something that isn’t technically correct. I’ll mark clarifications for these with a number. This article is aimed at those writing everyday (non-library) code, with little to no existing understanding of move semantics, to help get over the initial conceptual hurdle...

The pImpl Idiom

by Arne Mertz

From the article:

The pImpl idiom is a useful idiom in C++ to reduce compile-time dependencies. Here is a quick overview of what to keep in mind when we implement and use it...

C++ Weekly Episode 149: C++20's Lambda Usability Changes—Jason Turner

Episode 149 of C++ Weekly.

C++20's Lambda Usability Changes

by Jason Turner

About the show:

C++20 brings many different changes to lambdas, and two of these changes greatly affect the ways in which lambdas can be used. In this episode Jason discusses the use of lambdas in unevaluated contexts and the default constructability of lambdas in C++20.
