Ultimate Go Notebook

The Ultimate Go Notebook is the official companion book for the Ardan Labs Ultimate Go class. With this book, you will learn how to write more idiomatic and performant code with a focus on micro-level engineering decisions. This notebook has been designed to provide a reference to everything mentioned in class, as if they were your own personal notes.Our classes challenge every student to think about what they are doing and why and so does this book.- The first chapter helps you prepare your mind by establishing the mental models and design philosophy for the material you are about to review.- You will learn about the mechanics and semantics behind types, decoupling, error handling, concurrency, and more.- GENERICS! Learn about the new syntax coming to Go 1.18 for writing generic functions and types.- Four chapters on profiling, tracing, and stack traces help you learn critical debugging skills that will make you a more productive Go developer.- The last chapter features the many blog posts that are referenced throughout the book. If you have taken the class before, this notebook will be an invaluable resource for reminders on the content. If you have never taken the class, there is still tremendous value in this book as it covers more advanced topics not found in other books today."If you want to be a better Go developer, code reviewer, designer and architect, this is the book you want."When coming from another language, developers often struggle to grasp the fundamentals that make Go useful and unique. This book builds layers of foundational knowledge that will give you a deeper understanding into data semantics, decoupling, concurrency and tooling that is provided with the language.

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.

NEW YORK TIMES BESTSELLER • Being a Lazy Genius isn't about doing more or doing less. It’s about doing what matters to you. “I could not be more excited about this book.”—Jenna Fischer, actor and cohost of the Office Ladies podcast The chorus of “shoulds” is loud. You should enjoy the moment, dream big, have it all, get up before the sun, track your water consumption, go on date nights, and be the best. Or maybe you should ignore what people think, live on dry shampoo, be a negligent PTA mom, have a dirty house, and claim your hot mess like a badge of honor. It’s so easy to feel overwhelmed by the mixed messages of what it means to live well. Kendra Adachi, the creator of the Lazy Genius movement, invites you to live well by your own definition and equips you to be a genius about what matters and lazy about what doesn’t. Everything from your morning routine to napping without guilt falls into place with Kendra’s thirteen Lazy Genius principles, including: • Decide once • Start small • Ask the Magic Question • Go in the right order • Schedule rest Discover a better way to approach your relationships, work, and piles of mail. Be who you are without the complication of everyone else’s “shoulds.” Do what matters, skip the rest, and be a person again.

Discover an introduction of the CSP concurrency model by explaining GoRoutines and channels. Get a full explanation, including comprehensive text and examples, of all known GoF design patterns in Go. Who This Book Is For The target audience is both beginner- and advanced-level developers in the Go programming language. No knowledge of design patterns is expected. What You Will Learn All basic syntax and tools needed to start coding in Go Encapsulate the creation of complex objects in an idiomatic way in Go Create unique instances that cannot be duplicated within a program Understand the importance of object encapsulation to provide clarity and maintainability Prepare cost-effective actions so that different parts of the program aren't affected by expensive tasks Deal with channels and GoRoutines within the Go context to build concurrent application in Go in an idiomatic way In Detail Go is a multi-paradigm programming language that has built-in facilities to create concurrent applications. Design patterns allow developers to efficiently address common problems faced during developing applications. Go Design Patterns will provide readers with a reference point to software design patterns and CSP concurrency design patterns to help them build applications in a more idiomatic, robust, and convenient way in Go. The book starts with a brief introduction to Go programming essentials and quickly moves on to explain the idea behind the creation of design patterns and how they appeared in the 90's as a common "language" between developers to solve common tasks in object-oriented programming languages. You will then learn how to apply the 23 Gang of Four (GoF) design patterns in Go and also learn about CSP concurrency patterns, the "killer feature" in Go that has helped Google develop software to maintain thousands of servers. With all of this the book will enable you to understand and apply design patterns in an idiomatic way that will produce concise, readable, and maintainable software. Style and approach This book will teach widely used design patterns and best practices with Go in a step-by-step manner. The code will have detailed examples, to allow programmers to apply design patterns in their day-to-day coding.

You’ll understand how Go chooses to model concurrency, what issues arise from this model, and how you can compose primitives within this model to solve problems. Learn the skills and tooling you need to confidently write and implement concurrent systems of any size. Understand how Go addresses fundamental problems that make concurrency difficult to do correctly Learn the key differences between concurrency and parallelism Dig into the syntax of Go’s memory synchronization primitives Form patterns with these primitives to write maintainable concurrent code Compose patterns into a series of practices that enable you to write large, distributed systems that scale Learn the sophistication behind goroutines and how Go’s runtime stitches everything together

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.
