Teresa Johnsons Center Keynote: ThinLTO Whole Program Optimization: Past, Present and Future
by Jens Weller
From the article:
Whole program optimization enables higher performance in C++ applications, because of the expanded scope for analysis and optimization. Traditionally, whole program optimization is not scalable in memory or time, and doesn't support effective incremental builds. ThinLTO (Thin Link Time Optimization) is a new compilation model that...

This post revisits the well-known Insertion Sort algorithm as a way to learn and practice several new C++20 features such as concepts, ranges, and projections.
Programming with C++20's Concepts
by Daniel G Vergel
About the article
The article, written in Spanish, follows very closely the way I introduce these topics to my Computer Engineering students at the European University (Madrid, Spain). As previous posts, it tries to mitigate the lack of educational materials on modern C++ currently available in my native language. Code examples are nevertheless self-explanatory and may be of interest to non-Spanish readers as well.

A Tour of C++ Modules in Visual Studio
by Will Buik
From the article:
C++ module support has arrived in Visual Studio! Grab the latest Visual Studio Preview if you want to try it out. C++ modules can help you compartmentalize your code, speed up build times, and they work seamlessly, side-by-side with your existing code.
This preview only supports C++ modules in the IDE for MSBuild projects. While the MSVC toolset is supported by any build system, Visual Studio’s IDE support for CMake doesn’t support C++ modules yet. We will let you know once it is! As always, please try it out and let us know if you have any feedback...

More concepts.
Semantic requirements in concepts
by Andrzej Krzemieński
From the article:
The word ‘concept’ in the context of C++ generic programming has two meanings. The first is more abstract: it is the notion from the domain of Generic Programming (GP) in general. GP is not tied to any specific language: it is an approach to writing programs, and concepts are part of this approach. In this sense concepts have been with us since the inception of the STL. The second meaning is the keyword concept in C++20 with its associated semantics: its goal is to approximate the more abstract notion of a concept from GP, and this works only to some extent. One notable difference is that concepts in GP specify semantic requirements on types they constrain, and C++ concepts cannot express them directly.
In this post we will see how semantic requirements in concepts can break your program if you don’t pay attention to them, and what can be done in C++20 concepts to account for semantic requirements...

Tricks with Default Template Arguments
by Jonathan Müller
From the article:
Just like regular function parameters, template parameters can also have default parameters. For class templates, this behaves mostly just like default function arguments: if you pass fewer template arguments than required, default template arguments are used to fill the remaining places. However, for function templates, it gets more complicated as template parameters for functions can be deduced by the normal function arguments. This leads to some interesting side-effects. In particular, default arguments of template parameters don’t need to be put at the end!
Let’s take a look at a couple of things we can do with default template arguments...
