C++20 String Formatting Library: An Overview and Use with Custom Types
by Marc Gregoire
Summary of the talk:
C++20 introduced a nice formatting library with std::format(). This session will explain what the formatting library provides, how to use all of its functionality, and most importantly, how you can customize it so that you can use formatting strings that include your very own custom types and custom formatting parameters, and of course, how to handle errors.

Coercing deep const-ness
by Barry Revzin
From the article:
In C++, template deduction doesn’t allow for any conversion. A type matches the pattern, or it’s a deduction failure. But there’s one sort-of exception to this rule, and it’s an exception that everyone has taken advantage of...

A C++ Approach to Physical Units
by Mateusz Pusz
Summary of the talk:
This talk presents a new C++20 library for Dimensional Analysis and Physical Units handling. The essential requirements of the library are user-friendliness, compile-time safety, no runtime overhead, and easy extensibility. The syntax of the library is built around a few easy to learn concepts and strictly checked at compile time, which makes it easy to learn and very forgiving for the novice.
The talk presents motivating examples of why we need such a library, compares the library with other similar products on the market, describes the basic usage and interface, and highlights the benefits of the design choices made.
The talk is also a great showcase of practical usage of new C++20 features that make the library interface easier to use, maintain, and extend. Concepts, contracts, class types provided as non-type template parameters, and other C++20 features make a huge difference in how we can design Modern C++ code.

Ordering asynchronous updates with coroutines, part 1, part 2, part 3, part 4, part 5
by Raymond Chen
From the article:
I opined some time ago on the perils of holding a lock across a coroutine suspension point. But say you have a bunch of asynchronous activity that you want to serialize. How can you do that without a lock?
There are a few different scenarios in which you may need to protect asynchronous activity. We’ll look at them over the next few days...
