Ruby Cookbook

This is a book of recipes: solutions to common problems, copy-and-paste code snippets, explanations, examples, and short tutorials.
This book is meant to save you time. Time, as they say, is money, but a span of time is also a piece of your life. Our lives are better spent creating new things than fighting our own errors, or trying to solve problems that have already been solved. We present this book in the hope that the time it saves, distributed across all its readers,
will greatly outweigh the time we spent creating it.
