Go Systems Programming

Overview of this book

Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code. Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management. This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.

This chapter taught you some advanced Go features, including error handling, pattern matching and regular expressions, reflection, and unsafe code. Also, it talked about the strace(1) and dtrace(1) tools.

The next chapter will cover many interesting things, including the use of the new sort.slice() Go function, which is available in the latest Go version (1.8), as well as the big O notation, sorting algorithms, Go packages, and garbage collection.
