During CppCon I noticed how well AMA sessions went and that they are a great feature for an online conference. And for some time I knew that this years conference has some extra space for content due to its online nature.

std::exchange Patterns: Fast, Safe, Expressive, and Probably Underused
by Ben Deane
From the article:
This blog post has been a long time in the making. I gave a lightning talk on std::exchange at CppCon 2017; Jonathan first asked me to write something about std::exchange in January 2019; now here we are in the strange days of the second half of 2020. But although much has changed in the outside world, I would guess that not much has changed in most C++ codebases and in the minds of many C++ programmers with respect to using std::exchange. It could still do with more publicity and more recognition of potential use cases...

New C++ features in GCC 10
by Marek Polacek
From the article:
The GNU Compiler Collection (GCC) 10.1 was released in May 2020. Like every other GCC release, this version brought many additions, improvements, bug fixes, and new features. Fedora 32 already ships GCC 10 as the system compiler, but it’s also possible to try GCC 10 on other platforms (see godbolt.org, for example). Red Hat Enterprise Linux (RHEL) users will get GCC 10 in the Red Hat Developer Toolset (RHEL 7), or the Red Hat GCC Toolset (RHEL 8).
This article focuses on the part of the GCC compiler on which I spend most of my time: The C++ front end. My goal is to present new features that might be of interest to C++ application programmers. Note that I do not discuss developments in the C++ language itself, although some language updates overlap with compiler updates. I also do not discuss changes in the standard C++ library that comes with GCC 10.
We implemented many C++20 proposals in GCC 10. For the sake of brevity, I won’t describe them in great detail. The default dialect in GCC 10 is -std=gnu++14; to enable C++20 features, use the -std=c++20 or -std=gnu++20 command-line option. (Note that the latter option allows GNU extensions.)...

CLion 2020.3 EAP: CTest, Set Execution Point in Debug, Qt project templates, and MISRA Checks
by Anastasia Kazakova
From the article:
There are many useful changes and improvements planned for CLion 2020.3, and today we are ready to share some of them with you. CLion officially starts the 2020.3 Early Access Program today!
For those who just joined us, EAP builds are free and valid for 1 month, so you don’t need an active subscription to try them out. However, the quality of EAP builds is usually lower than that of releases. If you are wondering why taking part in an EAP is worth your while, please see this nice explanation by the WebStorm team...

CppCon 2020 Trip Report
by Conor Hoekstra
From the article:
This was my second time attending CppCon. The first time I attended was in 2019, when I gave my first CppCon presentation in two parts, Algorithm Intuition - although I personally recommend the C++Now 2019 version which is 30 minutes shorter.

CppCon 2020 Trip Report
by Shafik Yaghmour
From the article:
CppCon 2020 was online this year due to Covid-19. I was not sure what to expect from an online only conference. I had heard mildly positive feedback from recent online only conferences but this would be my first experience. For the most part the experience exceeded my expectations. There were were technical problems here and there but mostly it ran smoothly. It was fatiguing to watching videos for so long but since I was home I was able to stretch in between sessions and move around and that usually helped...

Qualifiers
by Barbara Geller and Ansel Sermersheim
About the video:
In this video we explore the many different kinds of qualifiers available in C++ and explore how they interact. We also cover why you would want to qualify your methods, and a surprising corner case in the way assignment is defined which can lead to very subtle bugs.
