title: Remove the date from a string
body: <p>Looking for some Regex help in Ruby.</p>
  
  <p>I have a string that is formated as so:</p>
  
  <pre><code>YYYY-MM-DD-title-of-post.markdown
  </code></pre>
  
  <p>I'm looking to use <code>gsub</code> or <code>sub</code> to remove the <code>YYYY-MM-DD</code> portion of the string and do further processing to it.</p>
  
  <p>I would like a Regular Expression to remove the date from the string. The date will never be in a different format.</p>
  
  <p>Thanks for the help!</p>
