You'll start with the basics-types, data structures, and control flows - and progress to advanced features like blocks, mixins, metaclasses, and beyond. more »
Jump Start Sinatra
This short SitePoint book provides readers with a fun and yet practical introduction to Sinatra, a framework that makes web development with Ruby extremely simple.

Computer Science Programming Basics in Ruby
If you know basic high-school math, you can quickly learn and apply the core concepts of computer science with this concise, hands-on book. Led by a team of experts, you'll quickly understand the difference between computer science and computer programming, and you'll learn how algorithms help you solve computing problems.

Each chapter builds on material introduced earlier in the book, so you can master one core building block before moving on to the next. You'll explore fundamental topics such as loops, arrays, objects, and classes, using the easy-to-learn Ruby programming language. Then you'll put everything together in the last chapter by programming a simple game of tic-tac-toe. more »

Understanding Computation
Finally, you can learn computation theory and programming language design in an engaging, practical way. Understanding Computation explains theoretical computer science in a context you'll recognize, helping you appreciate why these ideas matter and how they can inform your day-to-day programming.

Rather than use mathematical notation or an unfamiliar academic programming language like Haskell or Lisp, this book uses Ruby in a reductionist manner to present formal semantics, automata theory, and functional programming with the lambda calculus. It's ideal for programmers versed in modern languages, with little or no formal training in computer science. more »
