I gave a talk at the Interface Symposium on reproducible research in practice. I went first in the session, so the slides have a bit more background and philosophy. It was a great session; one of Jon Claerbout's colleagues spoke, Sergey Fomel, a founding author of Madagascar; Sorin Mitran from UNC Chapel Hill talked about reproducible research using virtual machines. Here is the Interface 2011 program. Here are my slides: shotwell-interface-2011.pdf

By the way, the symposium is sponsored by SAS and held on the SAS campus, in Cary, NC. I accidentally met John Sall at a mixer, and was apparently the only one who didn't know that he co-founded SAS! 🙂
