Learn Enough Ruby to Be Dangerous Write Programs, Publish Gems, and Develop Sinatra Web Apps with Ruby (Michael Hartl)

Learn Enough Ruby to Be Dangerous teaches you to write practical and modern programs using the elegant and powerful Ruby programming language. You’ll learn how to use Ruby for both general-purpose programming and for beginning web-application development. Although mastering Ruby can be a long journey, you don’t have to learn everything to get started… you just have to learn enough to be dangerous. You’ll begin by exploring the core concepts of Ruby programming using a combination of interactive Ruby and text files run at the command line. The result is a solid understanding of both object-oriented programming and functional programming in Ruby. You’ll then build on this foundation to develop and publish a simple self-contained Ruby package, or Ruby gem. You’ll then use this gem in a simple dynamic web application built using the Sinatra web framework, which you’ll also deploy to the live Web. As a result, Learn Enough Ruby to Be Dangerous is especially appropriate as a prerequisite to the Ruby on Rails Tutorial, a bestselling web- development tutorial by the same author.
