I’ve recently given two talks on Revealing Errors at LUG Radio Live USA and at Penguicon. I’ll be giving at least two more in the near future: today (June 18, 2008 — sorry for the late notice!) at MIT for Boston Linux Unix and at OSCON in Portland, Oregon on July 25.
There’s a post on Copyrighteous (my personal blog) with more details and links from my talks page to notes and slides.
So far, they’ve been successful and lots of fun. I travel frequently and am interested in doing more. Contact me if you’d be interested in organizing something.
