title: Definition of debugging, profiling and tracing
body: <p>Being new to systematic debugging, I asked myself what these three terms mean:</p>
  
  <ol>
  <li><strong>Debugging</strong></li>
  <li><strong>Profiling</strong></li>
  <li><strong>Tracing</strong></li>
  </ol>
  
  <p>Anyone could provide definitions?</p>
