Do you want to push Ruby to its limits? The Ruby Cookbook
is the most comprehensive problem-solving guide to today's hottest
programming
language. It gives you hundreds of solutions to real-world problems,
with clear explanations and thousands of lines of code you can use in
your own projects.

From data structures and algorithms, to integration with
cutting-edge technologies, the Ruby Cookbook has
something for every programmer. Beginners and advanced Rubyists
alike will learn how to program with:

Strings and numbers

Arrays and hashes

Classes, modules, and namespaces

Reflection and metaprogramming

XML and HTML processing

Ruby on Rails (including Ajax integration)

Databases

Internet services like email, SSH, and BitTorrent

If you need to write a web application, this book shows you
how to get started with Rails. If you're a system administrator who
needs to
rename thousands of files, you'll see how to use Ruby for this and
other everyday tasks. You'll learn how to read and write Excel
spreadsheets, classify text with Bayesian filters, and create PDF
files. We've even included a few silly tricks that were too cool to
leave out, like how to blink the lights on your keyboard.

The Ruby Cookbook is the most useful book yet
written about Ruby. When you need to solve a problem, don't reinvent
the wheel: look it up in
the Cookbook.
