The Go Programming Language is the authoritative resource for any programmer who wants to learn Go. It shows how to write clear and idiomatic Go to solve real-world problems. The book does not assume prior knowledge of Go nor experience with any specific language, so you’ll find it accessible whether you’re most comfortable with JavaScript, Ruby, Python, Java, or C++. The first chapter is a tutorial on the basic concepts of Go, introduced through programs for file I/O and text processing, simple graphics, and web clients and servers. Early chapters cover the structural elements of Go programs: syntax, control flow, data types, and the organization of a program into packages, files, and functions. The examples illustrate many packages from the standard library and show how to create new ones of your own. Later chapters explain the package mechanism in more detail, and how to build, test, and maintain projects using the go tool. The chapters on methods and interfaces introduce Go’s unconventional approach to object-oriented programming, in which methods can be declared on any type and interfaces are implicitly satisfied. They explain the key principles of encapsulation, composition, and substitutability using realistic examples. Two chapters on concurrency present in-depth approaches to this increasingly important topic. The first, which covers the basic mechanisms of goroutines and channels, illustrates the style known as communicating sequential processes for which Go is renowned. The second covers more traditional aspects of concurrency with shared variables. These chapters provide a solid foundation for programmers encountering concurrency for the first time. The final two chapters explore lower-level features of Go. One covers the art of metaprogramming using reflection. The other shows how to use the unsafe package to step outside the type system for special situations, and how to use the cgo tool to create Go bindings for C libraries. The book features hundreds of interesting and practical examples of well-written Go code that cover the whole language, its most important packages, and a wide range of applications. Each chapter has exercises to test your understanding and explore extensions and alternatives. Source code is freely available for download from http://gopl.io/ and may be conveniently fetched, built, and installed using the go get command.

THE NEW YORK TIMES BESTSELLER Transform your life using the Bullet Journal Method, the revolutionary organisational system and worldwide phenomenon. The Bullet Journal Method will undoubtedly transform your life, in more ways than you can imagine' Hal Elrod, author of The Miracle Morning In his long-awaited first book, Ryder Carroll, the creator of the enormously popular Bullet Journal organisational system, explains how to use his method to: * TRACK YOUR PAST: using nothing more than a pen and paper, create a clear, comprehensive, and organised record of your thoughts and goals. * ORDER YOUR PRESENT: find daily calm by prioritising and minimising your workload and tackling your to-do list in a more mindful and productive way. * PLAN YOUR FUTURE: establish and appraise your short-term and long-term goals, plan more complex projects simply and effectively, and live your life with meaning and purpose. Like many of us, Ryder Carroll tried everything to get organised - countless apps, systems, planners, you name it. Nothing really worked. Then he invented his own simple system that required only pen and paper, which he found both effective and calming. He shared his method with a few friends, and before long he had a worldwide viral movement. The system combines elements of a wishlist, a to-do list, and a diary. It helps you identify what matters and set goals accordingly. By breaking long-term goals into small actionable steps, users map out an approachable path towards continual improvement, allowing them to stay focused despite the crush of incoming demands. But this is much more than a time management book. It's also a manifesto for what Ryder calls "intentional living": making sure that your beliefs and actions align. Even if you already use a Bullet Journal, this book gives you new exercises to become more calm and focused, new insights on how to prioritise well, and a new awareness of the power of analogue tools in a digital world. *** This book has been printed with three different colour designs, black, Nordic blue and emerald.
