Hands-On System Programming with Go (實戰 Go 系統程式設計)

• 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

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
