||Beginning Ruby, 3rd Edition|
Learn the principles behind object-oriented programming and within a few chapters create a fully functional Ruby application. You'll also gain a basic understanding of many ancillary technologies such as databases, XML, web frameworks, and networking - some of which are needed as part of a fully functioning Ruby application.
Based on the bestselling first and second editions, Beginning Ruby 3rd Edition is a leading guide to learn Ruby from the ground up. The new edition of this book provides the same excellent introduction to Ruby as the previous editions plus updates for the newest version of Ruby 2.3 which includes new garbage collection support of symbol type objections, a new incremental garbage collector, memory management, vfork(2) with system and spawn functions and much more. This book can also be used as a textbook or companion to a textbook on beginning Ruby programming.
The light and agile Ruby programming language remains a very popular open source scripting option for developers building today's web and even some enterprise applications. And, now, Ruby also has applications using the Raspberry Pi, popular among hobbyists and makers. Many former Java developers still use Ruby on Rails today, the most popular framework for building Ruby applications.
||Rails 5 Revealed|
This short early adopter book details both how you'll upgrade existing web and other applications from Rails 4.2 to 5 and how to create new applications in Rails 5. The headline features, Rails API and ActionCable, are each looked at in detail, building small example projects to demonstrate how to build a JSON API, add real-time notifications to a page and how to create a single-page application.
All the breaking changes are shown, along with how to fix your app to work with the new API, and the improvements to ActiveRecord and the testing framework are fully detailed. After reading and using Rails 5 Revealed, you'll be poised to move forward with building your apps with the new Rails 5 as it stands now and when it finalizes.
This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake.
The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the reader's ability to make well-informed decisions on their own.
||Ruby Performance Optimization|
You don't have to accept slow Ruby or Rails performance. In this comprehensive guide to Ruby optimization, you'll learn how to write faster Ruby code - but that's just the beginning.

Alex Dymo will guide you through perils of memory and CPU optimization, profiling, measuring, performance testing, garbage collection, and tuning. You'll find that all those “hard” things aren't so difficult after all, and your code will run orders of magnitude faster.
