This book provides the reader with a comprehensive overview of the new open source programming language Go (in its first stable and maintained release Go 1) from Google. The language is devised with Java / C#-like syntax so as to feel familiar to the bulk of programmers today, but Go code is much cleaner and simpler to read, thus increasing the productivity of developers. You will see how Go: simplifies programming with slices, maps, structs and interfaces incorporates functional programming makes error-handling easy and secure simplifies concurrent and parallel programming with goroutines and channels And you will learn how to: make use of Go's excellent standard library program Go the idiomatic way using patterns and best practices in over 225 working examples and 135 exercises This book focuses on the aspects that the reader needs to take part in the coming software revolution using Go.
Danny thinks he must be the only seventeen-year-old guy in Cape Breton—in Nova Scotia, maybe—who doesn't have his life figured out. His buddy Kierce has a rule for every occasion, and his best friend Jay has bad grades, no plans and no worries. Danny's dad nags him about his post-high-school plans, his friends bug him about girls and a run-in with the cops means he has to get a summer job. Worst of all, he's keeping a secret that could ruin everything.
With stunning visuals and encyclopedic insight, the author of The Heights and The Works reveals how humans move across the globe by land, sea, and air In our digital age, it’s easy to forget that almost everything we enjoy about modern life depends on motion. We ride in cars and on buses and trains to work; enjoy food shipped over oceans; fly high in the sky to any point on the planet. Over the last century, the world has come to rely on its ability to move just about anywhere effortlessly. But what prompted this transformation? What inventions allowed it to happen? And how do the vehicles and systems that keep us in motion today—airports, trains, cars, and satellites—really work? Exploring our incredible interconnected world is the task of Kate Ascher’s The Way to Go: Moving by Sea, Land, and Air. Lusciously illustrated and meticulously researched, The Way to Go reveals the highly complex and largely invisible network of global transportation. How is cargo moved from inland factory to seaside port, and how is it transferred from shore to ship? How do ships and planes navigate their routes without landmarks? What happens under the hood of a car or in the undercarriage of a people mover? How did planes become cheaper than ships or trains? Why are some spaceships reusable and others not? What tools are needed to build today’s immense bridges and tunnels, and what ensures they don’t collapse? How does a helicopter really stay aloft? What happens when lightning strikes an airplane or when one satellite crashes with another? What will the car of tomorrow look like? Focusing on the machines that underpin our lives, Ascher’s The Way to Go also introduces the systems that keep those machines in business—the emergency communication networks that connect ships at sea, the automated tolling mechanisms that maintain the flow of highway traffic, the air control network that keeps planes from colliding in the sky. Equally fascinating are the technologies behind these complex systems: baggage-tag readers that make sure people’s bags go where they need to; automated streetlights that adjust their timing based on traffic flow; GPS devices that pinpoint where we are on earth at any second. Together these technologies move more people farther, faster, and more cheaply than at any other time in history. As our lives and our businesses become more entwined with others across the globe, there has never been a better time to understand how transportation works. Indispensable and unforgettable, Kate Ascher’s The Way to Go is a gorgeous graphic guide to a world moving as never before.

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.
This publication examines a variety of cases that demonstrate the aesthetic quality of transportation projects. These range from the relatively inexpensive painted "Gus Bus" in Grand Rapids to the large-scale project of designing the Montreal Metro. The purpose is to develop a fresh perspective on ways the visual appeal of transportation can be identified as a distinct element for consideration, and on the degree to which quality design contributes to the economics and function of transportation systems. A second purpose is to develop guidance and examples to assist transportation planners and citizens in dealing with these issues. The projects presented represent a wide range of costs and circumstances encountered in transportation planning. The study shows that the aesthetic benefits provided by quality materials, sensitive design, careful maintenance, and appropriate inclusion of works of art translate directly into increased patronage, cost efficiencies, and a better public environment.
In our digital age, it's easy to forget that almost everything we enjoy about modern life depends on movement.

So what does it really take to keep our world constantly moving? Exploring our incredible interconnected world is the task of Kate Ascher's The Way To Go. Lusciously illustrated and meticulously researched, The Way To Go reveals the highly complex and largely invisible network of global transportation.
"In this wickedly humorous book, Geoffrey Abbott describes the effectiveness of instruments of torture and reveals the macabre origins of familiar phrases such as 'gone west' or 'drawn a blank'. Covering everything from the preparation of the victim to the disposal of the body 'What a Way to Go' is everything you ever wanted to know about the ultimate penalty--and a lot you never thought to ask."--Publisher's description
