Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to get wg21 telecom video recording?
https://github.com/cplusplus/LEWG/wiki/2021-Telecons I want to learn some proposal and I found there're some telecons, but when I clicked the URL, it showed that I need to be invited...But how?

C++23: Near The Finish Line
This post only covers what is, and could have been, for consideration in the next two months of time before C++23 is considered feature complete. It doesn't cover proposals that where already discussed. If you look at the linked telecons schedule (https://github.com/cplusplus/LEWG/wiki/2021-Telecons) you'll see that constexpr math was discussed in June. You would need to further search in the papers status list (https://github.com/cplusplus/papers/issues) to see where each one is at in the road to C++23.

Thoughts on adding 'libraries' as a language concept
On 2021-05-11, hopefully. I haven't gotten confirmation from the authors yet.

Comparing asio to unifex
I'm curious what led you to this conclusion. If you ran into scalability issues with its static_thread_pool, then that's a known issue. If it's something else, the authors (of which I'm one) would love to know.

How does one actually build a C++ project
Instead of calling add_executable you will call add_library. Here is a (only moderately complicated) production example of a library that can be built standalone (along with tests and example executables), or as a subproject, where it builds only the library

How to write networking code now that will be easiest to adapt to the upcoming standard?
My original thought was to build my DDS implementation on top of libunifex in anticipation for standardization: https://github.com/facebookexperimental/libunifex

Executors/libunifex example project
I'm trying to understand how to work with the proposed executors in a project, but after watching Eric Niebler's cppcon talks (https://youtu.be/xLboNIf7BTg) and looking at the libunifex examples (https://github.com/facebookexperimental/libunifex/tree/main/examples) I still have a hard time wrapping my head around how to employ the sender/receiver pattern in a larger project.

Async/Await pattern in C++
You have coroutines in C++20 but there is also the executives proposal that's making it's way into C++23 that is available as a library under the name unifex that only requires C++14

Using Asio for asynchronous gRPC clients and servers
Asio-grpc makes exactly that possible by providing an Asio execution_context compatible interface to the CompletionQueue. It supports all types of RPCs (including generic ones), completion tokens, cancellation, as well as libunifex sender/receiver (if you want to try out what might become std::execution). The latest release (v1.7.0) also introduced a GrpcStream class for writing Rust/Golang select-style code.

"C++ makes it harder to shoot yourself, but when you do it blows your whole leg off"
All the network handling for Instagram and all other Meta apps on all platforms is handled by their own C++ library https://github.com/facebookexperimental/libunifex.

State of the art for CPOs (customization points) in C++?
This. I'd also like to mention libunifex. It's entirely based on tag_invoke and is a testament as to how much power it actually provides. On the other hand, it also proves how cumbersome it is to define CPOs with tag_invoke. But IMO it's a lot better than anything else anyone has ever created, and users usually don't need to define new CPOs, only library writers do, so there's that.

Why do we need networking, executors, linear algebra, etc in the Standard Library?
