copied!<h2>The Language</h2> <p><em>Ruby</em> is a recent programming language that shares most of its heritage with Perl and Smalltalk. You can see what Ruby looks like (and try it yourself) at <a href="http://tryruby.org/" rel="nofollow noreferrer">tryruby.org</a>. </p> <p>Just like you can use PHP to write web pages, you can do the same thing with Ruby.</p> <h2>The Framework</h2> <p><em>Ruby on Rails</em> is a set of software devices that help you to more easily write a website in Ruby. The primary things they try to facilitate ("make easy") are:</p> <ol> <li><strong>Storing related data</strong> (e.g. blog posts and the comments on them) to a database.</li> <li><strong>Accepting web requests</strong> and respond to them programmatically (e.g. check a user's password)</li> <li><strong>Composing HTML</strong> using your data, with layouts and templates to make it easier.</li> </ol> <p>"Rails," as it's called for short, is built with extreme prejudice towards certain application models, particularly MVC. What this means is that unlike PHP, where any <code>.php</code> source file is fair game for any bit of code, most code in a Rails application is written in a particular, conventional place. When people compare Rails to PHP, they often point this out.</p> <p>There's a lot I didn't cover, but these are Rails' most basic features. To see what it looks like, I'd suggest watching the infamous, <a href="http://rubyonrails.org/screencasts" rel="nofollow noreferrer">"Creating a Weblog..." screencast</a>.</p>
