C++20 Concurrency: part-3 request_stop and stop_token for std::jthread
by Gajendra Gulgulia
From the article:
In this article, we explore the latest feature of C++20’s std::jthreadthat allows one to signal a stop or cancellation to an already executing thread in certain situation...

More convenience.
C++20 Concurrency — Part 2: jthreads
by Gajendra Gulgulia
From the article:
In this part of the issue, I’ll discuss about the new std::jthread that helps us avoid the boilerplate code for joining the conventional std::thread in the first section. In the end, I’ll also mention about the std::swap algorithm’s specialization introduced in C++20 to swap the underlying thread handles associated with std::jthread ...

20 Smaller yet Handy C++20 Features
by Bartlomiej Filipek
From the article:
C++20 is huge and filled with lots of large features. Just to mention a few: Modules, Coroutines, Concepts, Ranges, Calendar & Timezone, Formatting library.
But, as you know, that’s not all.
Depending on how we count, C++20 brought around 80 Library features and 70 language changes, so there’s a lot to cover
In this article, I’ll show you 20 smaller C++20 things that are very handy and good to know. Ten language elements, and ten more for the Standard Library. Most of them with a cool example.
Let’s jump right into the text!

Improving Stability with Modern C++, Part 4 — Memory Management
by Ralph Kootker
From the article
When we started learning C++, we were all taught that every
newneeds a correspondingdelete. But sometimes we'd forget, or some code might throw an exception we weren't ready for, and then we'd leak memory. [...] With rare exceptions, C++ programmers should not have to writenewordeleteever again.

constexpr is one of the magic keywords in modern C++. You can use it to create code, that is then executed before the compilation process ends. This is the absolute upper limit for software performance.
Design and evolution of constexpr in C++
by Evgeny Shulgin
From the article:
The authors suffered greatly from the inability to use STL containers and wrote the std::vector and std::map analogues. Inside, these analogues have std::array that can work in constexpr. Proposal [P0784] Standard containers and constexpr studies the possibility of inputting STL containers in constexpr evaluations. Note. It's important to know what an allocator is. STL containers work with memory through it. What kind of an allocator — is specified through the tempte argument. If you want to get into the topic, read this article.

Outcome enters sustaining phase, goes ABI stable
by Niall Douglas
From the article:
After three years of maturing, I am pleased to announce that the Spring release of Outcome, an alternative error handling framework, will enter its sustaining phase and thus it will be able to formally guarantee ABI stability going forth. ABI stability is tested per commit by CI and the specifics of the guarantees is documented here...

The Interesting Evolution of std::equal_range
by Jonathan Boccara
From the article:
The good old std::equal_range STL algorithm, which has been in the STL since C++98, has evolved along with the versions of C++.
Starting from a poor interface and now a much better one, its story is an interesting example of how to improve the abstraction of an interface...

2021 C++ Standardization Highlights
by Botond Ballo
From the article:
The ISO C++ Standards Committee (also known as WG21) has not met in person since its February 2020 meeting in Prague, which I wrote about here.
However, the committee and its subgroups have continued their work through remote collaboration, and a number of notable proposals have been adopted into C++23, the next language version, in this way, with many others in the pipeline.
In this post, I will outline some of the highlights of the committee’s work in 2021. (The post will also cover some material from the latter part of 2020, a period when remote collaboration was already underway but which I have not covered in any previous post.) I’ve been less involved in the committee than before, so this post will not be as comprehensive as my previous trip reports, but I hope to share the proposals I’ve found most notable...
