focuses on user interface and "convention over configuration"; meaning, developers can focus on the unique qualities of their Web site or program rather than the building blocks that every application may require. Released in 2004, Ruby on

partner for Web-based software development firm 37signals. Joining the company in 2003, he has helped develop Basecamp, Campfire, Backpack and other Web-based applications. Working in similar ways like Web-based e-mail services like Yahoo!
