Key benefits

Learn how to write Unix and Linux system code in Golang v1.12
Perform inter-process communication using pipes, message queues, shared memory, and semaphores
Explore modern Go features such as goroutines and channels that facilitate systems programming

Description

System software and applications were largely created using low-level languages such as C or C++. Go is a modern language that combines simplicity, concurrency, and performance, making it a good alternative for building system applications for Linux and macOS. This Go book introduces Unix and systems programming to help you understand the components the OS has to offer, ranging from the kernel API to the filesystem. You'll then familiarize yourself with Go and its specifications. You'll also learn how to optimize input and output operations with files and streams of data, which are useful tools in building pseudo-terminal applications. You'll gain insights into how processes communicate with each other, and learn about processes and daemon control using signals, pipes, and exit codes. This book will also enable you to understand how to use network communication using various protocols, including TCP and HTTP. As you advance, you'll focus on Go's best feature - concurrency, which will help you handle communication with channels and goroutines, other concurrency tools to synchronize shared resources, and the context package to write elegant applications. By the end of this book, you will have learned how to build concurrent system applications using Go

Who is this book for?

If you are a developer who wants to learn system programming with Go, this book is for you. Although no knowledge of Unix and Linux system programming is necessary, intermediate knowledge of Go will help you understand the concepts covered in the book

What you will learn

Explore concepts of system programming using Go and concurrency
Gain insights into Golang s internals, memory models and allocation
Familiarize yourself with the filesystem and IO streams in general
Handle and control processes and daemons lifetime via signals and pipes
Communicate with other applications effectively using a network
Use various encoding formats to serialize complex data structures
Become well-versed in concurrency with channels, goroutines, and sync
Use concurrency patterns to build robust and performant system applications

I would really recommend this book to someone starting out, but not completely new to Go. It would be a solid intro into systems programming but also appropriate for any programmers starting to work in Go who is struggling with applying concurrency patterns. It can also serve as a nice refresher for more experienced developers, as it's a more advanced book. Get yourself a good intro book into Go programming (there are plenty out there), and then go for this book to get you into the systems side of it.A basic understanding of programming concepts and of Go are worked through the book from a system's perspective, discovering the details that the usual programming books won't cover. The book is concise and well written, with good examples and can ease you into using Go as a tool to do Linux systems programming.Having picked up this book as a helper for a toy implementation of network accessible file system in Go I am building, the patterns in the third part of the book came pretty handy. It goes and delivers a comprehensive overview of concurrency patterns to ease the transition.Going deeper into these topics is essential for anyone interested in aspects of security, handy if you're trying to design high-performance applications or for someone like me, just trying to expand my knowledge.
