AndyG shows us how Ranges and Coroutines make lazy expression evaluation easier in C++20.
We don't need no stinking expression templates
by Andy G
From the article:
In C++20, we finally get ranges (po896), which all but deprecates our need for expression templates.

Hi-perf dependency injection revisited
Phantom lambda type, partially applied class template, and deduction guides to support dependency injection
by Krzysztof Ostrowski
From the article:
Hi-perf dependency injection with construction of an injected type out of the user-defined lambda expressions. Minimal overhead, great benefits.

C++20 span tutorial
by Paul Silisteanu
From the article:
According to the latest C++20 draft, a span is a non-owning view over a contiguous sequence of objects. In other words, a std::span is, in essence, a pointer, length pair that gives the user a view into a contiguous sequence of elements. The elements of a span can be, for example, stored in one of the standard library sequential containers (like std::array, std::vector), in a built-in C-style array or in a memory buffer...

C++ 20: The Core Language
by Rainer Grimm
From the article:
My last post C++20: The Big Four started with an overview of concepts, ranges, coroutines, and modules. Of course, C++20 has more to offer. Today, let's continue my overview of the core language...

Executors - of which P0443R11 is one of the latest iterations - is poised to be the most fundamental library addition to C++23.
A Universal Async Abstraction for C++
By Corentin Jabot
From the article:
What is it about?
It is first and foremost a quest to find the most basic building blocks on top of which one could build asynchronous, concurrent and parallel code, whether it be on a small chip or a supercomputer with thousands of CPUs and GPUs.
This is not an easy task and has kept many experts and many companies busy for many years.

Yes. I need the memory management and need it better, than the standard library provides.
WIMSL: advanced memory management.
by Sergey Strukov
From the article:
This article describes some advanced memory management features, badly missed in the C++ standard library.
