Go Systems Programming: Master Linux and Unix system level programming with Go

I had high expectations of this book but it turned out to be a very poorly written material. Supposed to be a systems programming book it very vaguely covers important systems topics. Language used is very confusing especially in chapter two. For instance information about garbage collection is extremely hard to understand. It also seems to be artificially prolonged by splitting every small sample into part 1 - including packages, part 2 - main function and multi-line command output included doesn't help either. I cannot recommend this book to anyone. There are better books to get started in Go and plenty of information online about specific systems programming tasks.
