Seven years ago in Edinburgh, I presented my first ICSE paper Mining Version Histories to Guide Software Changes, co-authored with Peter Weißgerber, Stephan Diehl, and Andreas Zeller. Hard to believe, but at that time I still created slides with Latex (no Powerpoint or Keynote!!!) and I did not use any stock photography.
In 2004 was also the first instance of the Mining Software Repositories series. I had a paper with Peter Weißgerber on Preprocessing CVS Data for Fine-Grained Analysis.
