title: Ruby without Rails
body: <p>I already developed some simple applications in Rails (just to test) without any knowledge of Ruby, but now I want to change my life. I'm going to start learning Ruby (and never learn Rails for some personal reasons) and focus only on it, but before doing this I need tp know some things:</p>
  
  <ul>
  <li>How can I build GUI applications with it?
  
  <ul>
  <li>It's possible to use GTK with it?</li>
  <li>Where to download?</li>
  </ul></li>
  <li>Pros and cons of Ruby compared to Perl and Python?</li>
  <li>Pros and cons compared to C# and other .Net languages?</li>
  <li>How is the market of Ruby (without Rails) today?</li>
  <li>Where to be updated with the latest news (podcasts and blogs) of the Ruby world?</li>
  </ul>
