Ruby is one of the most important programming languages in use for web development. It powers the Rails framework, which is the backing of some of the most important sites on the web. The Pickaxe Book, named for the tool on the cover, is the definitive reference on Ruby, a highly-regarded, fully object-oriented programming language. This updated edition is a comprehensive reference on the language itself, with a tutorial on the most important features of Ruby - including pattern matching and Ractors - and describes the language through Ruby 3.3. Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way instead of helping you get the work done? Are you using Rails and want to dig deeper into the underlying Ruby language? If so, then we've got a language and book for you! Ruby is a fully object-oriented language. The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of programmers that want to get things done quickly and cleanly. This comprehensive reference manual for Ruby includes a description of the most important standard library modules, built-in classes, and modules. It also includes all the new and changed syntax and semantics introduced through Ruby 3.3, including pattern matching and Ractors, and describes the language through Ruby 3.3. What You Need: This book assumes you have a basic understanding of object-oriented programming. In general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs. Ruby runs on Windows, Linux, and MacOS.

Summary Get Programming with Haskell leads you through short lessons, examples, and exercises designed to make Haskell your own. It has crystal-clear illustrations and guided practice. You will write and test dozens of interesting programs and dive into custom Haskell modules. You will gain a new perspective on programming plus the practical ability to use Haskell in the everyday world. (The 80 IQ points: not guaranteed.) Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Programming languages often differ only around the edges—a few keywords, libraries, or platform choices. Haskell gives you an entirely new point of view. To the software pioneer Alan Kay, a change in perspective can be worth 80 IQ points and Haskellers agree on the dramatic benefits of thinking the Haskell way—thinking functionally, with type safety, mathematical certainty, and more. In this hands-on book, that's exactly what you'll learn to do. What's Inside Thinking in Haskell Functional programming basics Programming in types Real-world applications for Haskell About the Reader Written for readers who know one or more programming languages.

Software applications have taken over our lives. We use and are used by software many times a day. Nevertheless, we know very little about the invisibly ubiquitous workers who write software. Who are they and how do they perceive their own practice? How does that shape the ways in which they collaborate to build the myriad of apps that we use every day? Coderspeak provides a critical approach to the digital transformation of our world through an engaging and thoughtful analysis of the people who write software. It is a focused and in-depth look at one programming language and its community – Ruby - based on ethnographic research at a London company and conversations with members of the wider Ruby community in Europe, the Americas and Japan. This book shows that the place people write code, the language they write it in and the stories shared by that community are crucial in questioning and unpacking what it means to be a ‘coder’. Understanding this social group is essential if we are to grasp a future (and a present) in which computer programming increasingly dominates our lives. Praise for Coderspeak 'Heurich perfectly captures the generous camaraderie, quirky spirit and intellectual curiosity at the heart of the Ruby world. Packed with tidbits of Ruby history, code snippets, and fascinating conversations, this book has something to teach every Rubyist.' Jemma Issroff, Ruby Core Team
