Advent of Go Microservices
Advent of Go Microservices
About the Book
Are you stuck writing boilerplate code for your microservice?
The book takes you on a 24 chapter adventure where you'll learn how to get rid of the chore work that is keeping you from actually writing your microservices. We'll resort to automation for taking care of your data structures, SQL migrations, API endpoints and routing, updating your documentation, along with CI and monitoring - all the things you need, but at the same time don't need to do by hand.

C++20
Rainer GrimmC++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.
