API foundations in Go (Engineer)
API foundations in Go
You've mastered PHP and are looking at Node.js? Skip it and try Go.
About the Book
This book is the distillation of more than a decade of web development experience. The knowledge behind it is powering some of the top-tier web sites in the world, serving millions and billions of requests. If you're thinking of writing an API today, and want to start with your right foot forward: this is the book which should give you all the tools you need. When you choose Go, you're ready to scale from the start.
In general it was quite easy to follow and gave me a good bunch of confidence to attack some more web dev with golang. Including copying all the code, writing it for practice, it took about 4 hours of focused effort.

C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.
