Overview of this book

Often referred to (incorrectly) as Golang, Go is the high-performance systems language of the future. Mastering Go, Second Edition helps you become a productive expert Go programmer, building and improving on the groundbreaking first edition. Mastering Go, Second Edition shows how to put Go to work on real production systems. For programmers who already know the Go language basics, this book provides examples, patterns, and clear explanations to help you deeply understand Go’s capabilities and apply them in your programming work. The book covers the nuances of Go, with in-depth guides on types and structures, packages, concurrency, network programming, compiler design, optimization, and more. Each chapter ends with exercises and resources to fully embed your new knowledge. This second edition includes a completely new chapter on machine learning in Go, guiding you from the foundation statistics techniques through simple regression and clustering to classification, neural networks, and anomaly detection. Other chapters are expanded to cover using Go with Docker and Kubernetes, Git, WebAssembly, JSON, and more.

Exercises

  • Develop a File Transfer Protocol (FTP) client in Go.
  • Next, try to develop an FTP server in Go. Is it more difficult to implement the FTP client or the FTP server? Why?
  • Try to implement a Go version of the nc(1) utility. The secret when programming such fairly complex utilities is to start with a version that implements the basic functionality of the desired utility, before trying to support every possible option.
  • Modify TCPserver.go so that it returns the date in one network packet and the time in another.
  • Modify TCPserver.go so that it can serve multiple clients in a sequential way. Notice that this is not the same as being able to serve multiple requests concurrently. Put simply, use a for loop so that the Accept() call can be executed multiple times.
  • TCP servers, such as fiboTCP.go, tend to terminate when they receive a given signal, so add signal handling code to...
