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...

CppCon 2019: C++20: The small things--Timur Doumler

By Adrien Hamelin | Aug 10, 2020 11:58 AM | Tags: community c++20

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!

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.

Everyday Efficiency: In-Place Construction (Back to Basics?)

by Ben Deane

Summary of the talk:

Efficient C++ has always been about minimizing copies. This practically-focused
talk is about how to do that when working with move semantics, perfect
forwarding and STL containers, or non-STL containers that present similar
interfaces.

In-place construction is an easily stated goal, but can be really fiddly to get
right, especially given the foibles of various container interfaces. We'll talk
about copy elision; when to use emplace, insert, or other methods; vectors,
maps, optionals, variants; and how things change from C++11 through C++20.
Attendees will learn why in-place construction is beneficial and exactly how to
achieve optimal efficiency with the various standard container types.
