The entire 6-DVD Making Better Software series, which was produced after Aardvark'd, is now free on YouTube as well: https://www.youtube.com/watch?v=qXZ75Ds5vOs&list=PLXOSex6PRP...

I remember when Fog Creek first announced that series and it cost a jillion dollars. A Fog Creek sales rep at the Fog Creek World Tour in 2010 in Atlanta gave me an "extra" copy of the DVD set and I felt like I had stolen something.
