Networking and Asynchronous Design

Chris Kohlhoff is a networking expert (among other expertises, including C++), creator of the Asio library and initial author of the C++ Networking Technical Standard (TS). Asio is available here as well as at Chris' GitHub site. Asio forms the basis for the C++ Networking Technical Standard (TS), which will be standardized in C++ 23 or C++ 26 (or thereabouts). Currently the Chops Net IP library uses the stand-alone Asio repository from Chris' GitHub account.
Vinnie Falco is the author of the Boost Beast library, available at Boost.org. Beast is an excellent building block library for asynchronous (and synchronous) HTTP and WebSocket applications. The Beast library uses Asio. Vinnie is proficient in C++ including presenting at CppCon and is also active in blockchain development and other technology areas. Vinnie has a GitHub site. While Chops Net IP does not depend on Beast, the choices and design rationale made by Vinnie in implementing Beast are highly helpful.
Kirk Shoop is a C++ expert, particularly in the area of asynchronous design, and has presented multiple times at CppCon. He is a co-author of the Unified Executors Proposal for C++ and has a GitHub site.

Anthony Williams is the author of Concurrency in Action, Practical Multithreading. He is a recognized expert in concurrency including Boost Thread and C++ standards efforts. It is highly recommended to buy his book, whether in paper or electronic form, and there is now a second edition of Concurrency in Action. Anthony has a web site and a GitHub site.

Martin Moene is a C++ expert and member and former web editor of accu-org. He provides an excellent set of header-only libraries that implement many useful C++ library features, both C++ 17 as well as future C++ standards. These include std::optional, std::variant, std::any, and std::byte (from C++ 17) as well as expected and ring_span (possibly in a future C++ standard). He also has multiple other useful repositories including an implementation of the C++ Guideline Support Library (GSL). Martin has a GitHub site.
Justas Masiulis provides a nice circular buffer implementation used in the Utility Rack wait_queue unit test.

Andrzej Krzemieński is a C++ expert and proficient blog author. This blog is influential, well written, and a significant portion of the Chops code is directly influenced by it.
Bjørn Reese blogs about many topics in C++ at the expert level and is active with the Boost organization.
Richard Hodges is a prolific C++ expert with over 1,900 answers on StackOverflow as well as numerous discussions relating to C++ standardization and has a GitHub site.
Vittorio Romeo is a blog author and C++ expert with a web site and a GitHub site. Vittorio's blog is excellent and well worth reading.
Blitz Rakete is a student software developer who has the user id of Rakete1111 on many forums and sites (including Stackoverflow) and has a GitHub site.
Anders Schau Knatten has a C++ blog and is the creator and main editor of the C++ quiz site. One of the best overviews of lvalues, rvalues, glvalues, prvalues, and xvalues is available here.
Jonathan Müller is very active in the C++ universe and is well known as "foonathan". His has a blog and his article Rvalue References in APIs is a must read for library designers.

Modern CMake design is important, although not a lot of reference material is available. See Daniel Pfeifer's C++Now 2017 talk on Effective CMake and Manuel Binna's GitHub page.
An excellent book is Professional CMake, A Practical Guide by Craig Scott.
Effective CMake, by Kai Wolf, is under development. Another book is under development on GitHub.

Phil Nash is the author of the Catch C++ unit testing library. The Catch library is available here.

Sy Brand's article on writing clear documentation has been invaluable. In addition, Sy is a well known C++ expert and presenter, known as TartanLLama, and his blog is available here.
Diagrams in the Connective C++ documentation are created using draw.io.

The Boost libraries collection is a high quality set of C++ libraries, available here.
