Concepts in C++20: An Evolution or a Revolution?
by Rainer Grimm
From the article:
Let me conclude my series to concepts with this meta-post. Are concepts an evolution or a revolution in C++? The answer to this question bothered me quite a time...

Quick A: It is possible.
Recently on SO:
Setting a vector equal to {};
It's valid (since C++11).
std::vectorhas an overloaded operator= takingstd::initializer_list.

Various Ways of Applying a Function to the Elements of a Collection in C++
by Jonathan Boccara

C++20: Define the Concept Regular and SemiRegular
by Rainer Grimm
From the article:
When you want to define a concrete type that works well in the C++ ecosystem, you should define a type that "behaves link an int". Formally, your concrete type should be a regular type. In this post, I define the concepts Regular and SemiRegular...

SG-11, the study group charged of all things concurrency and parallelism made forward progress and sent the proposal to LEWG - with the hope of landing a future revision in the C++23 draft. This is rather big news given that this work has been brewing for about a decade.
A Universal I/O Abstraction for C++
by Corentin Jabot
From the article:
The year is 2020 and even consummer CPUs feature double digits number of cores, storage offers 10GB/s read speeds and networks have to accommodate ever-growing traffic.
For a long time, the C++ committee seemed to think that either async file I/O didn’t make sense or was fundamentally irreconcilable with networking. This belief would lead to two inter-incompatible APIs in the standard, which would be a nightmare in term of usability (aka ASIO and AFIO).
It seems that there is finally a way to resolve these divides:
io_uring offers very high performance I/O which doesn’t discriminate on device type.
Sender Receiver provides the composable, low-cost, non-allocating abstraction while offering a simple mental model for asynchronous operations lifetime.
Coroutines make asynchronous i/o dead simple for the 99% use case.
Asynchronous Networking is nice.Asynchronous I/O is better.
AWAIT ALL THE THINGS!

C++ in 2020
by Jens Weller
From the article:
Now where the year is a few weeks old, lets see whats ahead for C++ in 2020!
I'll cover the Meeting C++ Community Survey, Conferences, Libraries & Releases, ISOCPP and C++20.
This blog post is based on a newsletter, which is based on a talk I gave at my User Group in Düsseldorf two weeks ago. Come and visit our meetings at the 3rd Wednesday of the month! My C++ User Group is also still looking for speakers in 2020, contact me if you're in town!

A taste of functional stack of effects.
Decorating with a side effect
by Krzysztof Ostrowski
From the article:
Logging is one of such overused features, that leads to costly side effects (consider distributed logging, a DLT, prevalent in automotive industry). This article describes a technique that is used to extract side effects brought by logging, and then compose with them back in a well defined manner.

C++20 Reference Card
by Bartlomiej Filipek
From the article:
While the C++20 Standard is still being finalised and polished, we know all of its core features. At first, the new specification of the language might sound complex and overwhelming. That’s why, if you want to have an overview of the core elements and get the bigger picture, you can have a look at my new reference card...
