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, Third 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. 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. What You'll LearnDiscover the fundamentals of Ruby and its object-oriented building blocksUse the Ruby libraries, gems, and documentationWork with files and databasesWrite and deploy Ruby applicationsHarness the various Ruby web frameworks and how to use themDo network programming with Ruby Who This Book Is ForBeginning programmers, programmers new to Ruby, and web developers interested in learning and knowing the foundations of the Ruby programming language.

This book is for anyone who wants to master Linux from the command line. When writing it, I had in mind system administrators, software developers, and enthusiastic users who want to get things going from the Linux command line. For beginning users, this may be a daunting task, as Linux commands often have many options documented only in pages that are not that easy to understand. This book is distribution agnostic. That is, while writing it, I've checked all items against Ubuntu, Red Hat, and SUSE. Since most distributions are quite similar to one of these three, this book should help you with other distributions as well. There is only one item in the book that is not distribution agnostic: the Appendix, which explains how to install OpenSUSE. I've chosen to cover installation of just one distribution, because if you don't have any Linux installed yet, you probably don't care what you install. If you do care what distribution to work with, you probably have it installed already.
