There was a SDN event recently - 18th May 2010. Fabio Dell'Aria took two sessions on this event: "How to find the exception source line of a just delivered software" and "How to prevent source code bugs and speed-up the testing phase".
I had prepared two presentations for these sessions in OpenOffice Impress and some accompanied text in OpenOffice Writer for this event. And I thought that you may be interested in those materials, so I decided to publish them.
You can download both sessions in one archive here.
