Chapter 1
Hello, dRuby

Let’s get familiar with dRuby. dRuby stands for “distributed Ruby.” It’s one of the standard libraries that comes with the Ruby core code, and you can use it to write distributed programming apps without the hassle of installing and configuring additional components. In this chapter (because it’s an unwritten rule), we’ll start with “Hello, World” and then create a small reminder application that you can access from multiple terminals.
