The C++ Standard Library: The Third Edition includes C++20
by Rainer Grimm
From the article:
I proudly present the third edition of my book: "The C++ Standard Library". The book includes C++20.
With the current C++20 standard, C++ has many libraries to offer. My book's key idea is to give you the necessary information to all the C++ standard libraries in a concise way.

Introducing ACCU Online - A Local Group With a Global Reach
by Bob Schmidt
From the article:
ACCU London is proud to host an ACCU Online event - a rescheduling of Chris Oldwood's previously cancelled "A Test of Strength" talk.
The event will be hosted virtually, on Remo. This will also give us the social and networking aspect of meet-ups that we miss from the in-person version.
When: Wednesday, 12th August 2020, 19:00 start...

This year, CppCon 2020 is going virtual. The dates are still the same – September 14-18 – and we are aiming for the CppCon live event to have pretty much everything you’re familiar with at CppCon except moved online: multiple tracks including “back to basics” and a new “embedded” track; live speaker Q&A; live talk time zones friendly to Americas and EMEA (and we’re going to try to arrange around-the-clock recorded repeats in all time zones, where speakers who are available can be available for live Q&A in their repeated talks too, and we’ll do that if it’s possible – but we’re still working on it!); virtual tables where you can interact face-to-face online with other attendees just like at the physical event; virtual exhibitor spaces where you can meet the folks on your favorite product’s teams to ask them question face-to-face; pre- and post-conference classes; and even the CppCon house band playing live before every plenary session. All talk recordings will be freely available as usual on YouTube a month or two after the event, but everything else above will be available only live during CppCon week.
To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2020 – all the spirit and flavor of CppCon, this year all virtual and online!
C++20: The small things
by Timur Doumler
Summary of the talk:
C++20 comes with some big new language features: modules, coroutines, concepts, spaceship, and many new libraries. But apart from all those, C++20 also offers many small language improvements, making C++ more powerful and expressive, but also safer and more consistent.
This talk is an overview over all those smaller additions to the core language that will make your life easier. We will discuss much-needed improvements to existing facilities such as lambdas, CTAD, structured bindings, and initialisation, as well as brand-new language utilities that you may not yet have heard about!

How to write a lambda.
Lambda Week: Syntax changes, C++11 to C++20
by Bartlomiej Filipek
From the article:
Let’s start the week with Lambda Expressions. The plan is to have a set of concise articles presenting core elements of lambda expressions. Today you can see how the syntax has evolved since C++11 and what the latest changes in C++20 are.

All about capture.
C++ Lambda Week: Capturing Things
by Bartlomiej Filipek
From the article:
We’re in the second day of the lambda week. Today you’ll learn about the options you have when you want to capture things from the external scope. Local variables, global, static, variadic packs, this pointer… what’s possible and what’s not?

A Unifying Abstraction for Async in C++
by Eric Niebler, David Hollman
Summary of the talk:
Async in C++ is in a sad state. The standard tools -- promises, futures, threads, locks, and std::async -- are either inefficient, broken, or both. Even worse, there is no standard way to say _where_ work should happen. Parallel algorithms, heterogeneous computing, networking & IO, reactive streams, and more: all critically important foundational technologies that await a standard abstraction for asynchronous computation.
In this talk, Eric Niebler and David Hollman dig into the Standard Committee's search for the basis operations that underpin all asynchronous computation: the long-sought Executor concept. The latest iteration of Executors is based on the Sender/Receiver programming model, which provides a generalization of many existing paradigms in asynchronous programming, including future/promise, message passing, continuation passing, channels, and the observer pattern from reactive programming. It also has surprising and deep connections to coroutines, which further demonstrates the model’s potential to be a truly unifying abstraction for asynchronous programming in C++20 and beyond.
Eric and David will present the short-term and long-term directions for Executors in ISO Standard C++, illustrating the design by walking through several implementation examples. They will talk about the direct connection between coroutines and the Sender/Receiver model and discuss what it means for the future of asynchronous APIs in C++. Finally, they will cover how the restrictions imposed by the Executors model should affect the way you write code today so your code is ready for the next big revolution in parallel and concurrent C++ programming.

More Powerful Lambdas with C++20
by Rainer Grimm
From the article:
Thanks to C++20, lambdas become more powerful. From the various lambda improvements, template parameters for lambdas are my favorite ones.

Various Template Improvements with C++20
by Rainer Grimm
From the article:
Admittedly, I present in this post a few small improvements to templates and to C++20 in general. Although these improvements may seem not so impressive to you, they make C++20 more consistent and, therefore, less error-prone when you program generic.
