From Ruby to Golang by Joel Bryan Juliano Pdf

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!

Learning Go by Jon Bodner Pdf

Go is rapidly becoming the preferred language for building web services. While there are plenty of tutorials available that teach Go's syntax to developers with experience in other programming languages, tutorials aren't enough. They don't teach Go's idioms, so developers end up recreating patterns that don't make sense in a Go context. This practical guide provides the essential background you need to write clear and idiomatic Go. No matter your level of experience, you'll learn how to think like a Go developer. Author Jon Bodner introduces the design patterns experienced Go developers have adopted and explores the rationale for using them. You'll also get a preview of Go's upcoming generics support and how it fits into the language. Learn how to write idiomatic code in Go and design a Go project Understand the reasons for the design decisions in Go Set up a Go development environment for a solo developer or team Learn how and when to use reflection, unsafe, and cgo Discover how Go's features allow the language to run efficiently Know which Go features you should use sparingly or not at all

Ruby in the Sky by Jeanne Zulick Ferruolo Pdf

A Washington Post KidsPost Summer Book Club Read Twelve-year-old Ruby Moon Hayes does not want her new classmates to ask about her father. She does not want them to know her mother has been arrested. And she definitely does not want to make any friends. Ruby just wants to stay as silent and invisible as a new moon in the frozen sky. She and her mother won’t be staying long in Vermont anyway, and then things can go back to the way they were before everything went wrong. But keeping to herself isn’t easy when Ahmad Saleem, a Syrian refugee, decides he’s her new best friend. Or when she meets “the Bird Lady,” a recluse named Abigail who lives in a ramshackle shed near Ruby’s house. Before long Ahmad and Abigail have become Ruby’s friends—and she realizes there is more to their stories than everyone knows. As ugly rumors begin to swirl around the people Ruby loves, she must make a choice: break her silence, or risk losing everything that’s come to mean so much to her. Ruby in the Sky is a story of the walls we hide behind, and the magic that can happen when we’re brave enough to break free.

Practical Object-Oriented Design in Ruby by Sandi Metz Pdf

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. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus 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

The Go Programming Language by Alan A. A. Donovan,Brian W. Kernighan Pdf

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.

Design Patterns in Ruby by Russ Olsen Pdf

Praise for Design Patterns in Ruby "Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work." —Steve Metsker, Managing Consultant with Dominion Digital, Inc. "This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read." —Peter Cooper "This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book." —Mike Stok "Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby." —Rob Sanheim, Ruby Ninja, Relevance Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code. After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse. Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks. Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.

Letters From Ruby by Adam Thomas Pdf

When the newly ordained Episcopal priest Rev. Calvin Harper arrives in Victory, West Virginia, to be the pastor at an ailing parish, he has no idea how much he still has to learn about being a priest. Thankfully, Ruby Redding takes the young man under her wing and teaches him everything she has learned throughout her long, storied life. Seminary never taught Calvin that the only true way to be a witness to God's presence in this world is to remain in relationship with people no matter what life throws at them. His studies never taught him that detachment is the bane of ministry. He never learned that deep grief comes only from deep love. But in his first year in Victory, Calvin learns all this and more from Ruby, a woman so full of God's light that it can't help but spill onto the people around her.
