    Many exercises are presented to help reinforce the lessons learned, and answers to the exercises are given in a new appendix.Most of the remaining chapters are dedicated to the reference material, which describes in detail the standard features of Scheme included in the Revised$^5$ Report on Scheme and the ANSI/IEEE standard for Scheme.Numerous examples are presented throughout the introductory and reference portions of the text, and a unique set of extended example programs and applications, with additional exercises, are presented in the final chapter. Reinforcing the book's utility as a reference text are appendices that present the formal syntax of Scheme, a summary of standard forms and procedures, and a bibliography of Scheme resources.The Scheme Programming Language stands alone as an introduction to and essential reference for Scheme programmers. it is also useful as a supplementary text for any course that uses Scheme.The Scheme Programming Language is illustrated by artist Jean-Pierre Hébert, who writes Scheme programs to extend his ability to create sophisticated works of digital art.R. Kent Dybvig is Professor of Computer Science at Indiana University and principal developer of Chez Scheme.

    With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. With this book, you'll learn specific ways to write command-line applications that are easy to use, deploy, and maintain, using a set of clear best practices and the Ruby programming language. This book is designed to make any programmer or system administrator more productive in their job. Now updated for Ruby 2.Writing a command-line application that's self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, because it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Plus, Ruby has the support of a rich ecosystem of open source tools and libraries.Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason why a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users.With Ruby, the command line is not dead. Long live the command line.

    With this guide, pioneering Go programmer Mark Summerfield shows how to write code that takes full advantage of Go's breakthrough features and idioms. Both a tutorial and a language reference, "Programming in Go" brings together all the knowledge you need to evaluate Go, think in Go, and write high-performance software with Go. Summerfield presents multiple idiom comparisons showing exactly how Go improves upon older languages, calling special attention to Go's key innovations. Along the way, he explains everything from the absolute basics through Go's lock-free channel-based concurrency and its flexible and unusual duck-typing type-safe approach to object-orientation. Throughout, Summerfield's approach is thoroughly practical. Each chapter offers multiple live code examples designed to encourage experimentation and help you quickly develop mastery. Wherever possible, complete programs and packages are presented to provide realistic use cases, as well as exercises. Coverage includes:-- Quickly getting and installing Go, and building and running Go programs -- Exploring Go's syntax, features, and extensive standard library -- Programming Boolean values, expressions, and numeric types -- Creating, comparing, indexing, slicing, and formatting strings -- Understanding Go's highly efficient built-in collection types: slices and maps -- Using Go as a procedural programming language -- Discovering Go's unusual and flexible approach to object orientation -- Mastering Go's unique, simple, and natural approach to fine-grained concurrency -- Reading and writing binary, text, JSON, and XML files -- Importing and using standard library packages, custom packages, and third-party packages -- Creating, documenting, unit testing, and benchmarking custom packages

    "I like how the author builds quite high expectations in the introduction of the book, and manages to fulfill them fully throughout the book.""I am amazed at his ability to focus on teaching people, like me, who have done basically nothing with cameras other than point and shoot. There is a wealth of useful and understandable information in this book,...""I've been photographing for years since first SLR in 1960s and yet I found much of interest and some I was unfamiliar with. I especially appreciated the clear, concise presentation."" Even us 'know-it-alls' are surprised by the information that cleared-up some uncertain items that had existed too long.""As a former photography student who learned almost nothing over a two year period, I can now say that I fully understand the terminology and possess the technical skill to take better photographs and possibly revisit my dream of becoming a sports photographer." Whether You are New to Photography,making the transition from Film to Digital Photography, or just want to improve your skills, this book will save you TIME and MONEY! No more intimidation! If you understand how Digital Cameras work, every photo becomes a learning experience. Many people are walking around with expensive cameras that they barely know how to use and others are missing great photo opportunities because they have been misinformed by well-meaning friends. This book is based on the premise that a solid understanding of photographic equipment results in a faster learning curve and better photos. The technology is actually quite simple when it is broken down and clearly explained.Without an understanding of cameras, you are at the mercy of others in all your buying decisions. You will only scratch the surface of your camera's capabilities until you take on its manual settings. You need to read this book because: It will take the confusion out of Photographic terminology by clearly defining every important term used. Your learning will be enhanced by 120 charts and photos that will simplify discussions and help you to remember what you learned. You will learn why buying a camera based on Megapixels alone is a bad idea. You will learn how sensor size and lens selection affect image quality more than any other factors.
