Imagine that you like to learn a new programming language, and you start by leveraging what you already know and bridge the gap in learning specific parts of the new language. This book was created on that idea, it starts with using my existing language knowledge and experience to breakdown Go into familiar Ruby concepts and implementations. The first thing I did to learn Go professionally is to relate to what I know in Ruby. I’ve been a professional Ruby programmer since 2009 and in over a decade of professional experience working as a software engineer, I have worked on multiple programming languages. And proven personally that it’s easier to learn a programming concept from something familiar to me. This helps me to learn the new language faster, which also means being productive much faster as well. This book was created on my first-hand experience of learning Go from my existing knowledge and experience in Ruby. The book was carefully thought from ground-up, collecting familiar patterns, abstracts, and analogs in Ruby, and relate it with a proper implementation in Go. By teaching familiar implementations found in Ruby, you will see the correlation between the two languages, establishing familiar concepts to give you enough knowledge to be comfortable with Go and to start programming with it. Go is an easy language to work with, it’s modern, flexible, powerful and fast. It compiles to binary which gives it an ability for a binary distribution that runs on different platforms, and Go has almost in par performance with C, with package support, memory safety, automatic garbage collection and concurrency built-in. And you get all the nice features from a statically typed language, which IDEs can make use of, and so also improving your development workflow. Notable open-source projects are built using Go (i.e. Docker, Kubernetes, Etherium and Terraform to name a few), this gives you an advantage because those platforms have APIs and SDKs readily available in Go natively for you to use. And many global companies have been using Go in production (i.e. Google, Netflix, Dropbox, Heroku and Uber to name a few), proving that it has been battle-tested and powerful mature language to based your work into. Go is created by an interesting mixed of people. Google is the company that funded Go’s development, and the authors of Go who designed the language are mainly Robert Griese- mer (worked on V8 Javascript Engine, Java HotSpot VM, and the Strongtalk system), Rob Pike (known for Plan 9 and UTF-8), and Ken Thompson (known for Unix, C programming language, Plan 9, UTF-8 and Inferno to name a few). This book will definitely help you get started with Go from your existing Ruby knowledge, and start to hit the ground fast, running!

It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness. Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. This book focuses squarely on object-oriented Ruby application design. Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

Based on the bestselling first edition, Beginning Ruby: From Novice to Professional, Second Edition is the leading guide for every type of reader who wants to learn Ruby from the ground up. The new edition of this book provides the same excellent introduction to Ruby as the first edition plus updates for the newest version of Ruby, including the addition of the Sinatra and Ramaze web application frameworks and a chapter on GUI development so developers can take advantage of these new trends. Beginning Ruby starts by explaining the principles behind object-oriented programming and within a few chapters builds toward creating a full Ruby application. By the end of the book, in addition to in-depth knowledge of Ruby, you'll also have basic understanding of many ancillary technologies such as SQL, XML, web frameworks, and networking. Introduces readers to the Ruby programming language Takes readers from basic programming skills to web development with topics like Ruby-based frameworks and GUI programming Covers many ancillary technologies in order to provide a broader picture (e.g., databases, XML, network daemons)
