My research area is on malware detection, so I usually follow the Giraffe Chapter talks and their slides.
Slides #1 in Kuala Lumpur, Malaysia[PDF]
Slides #2, dated 2012 for CCC [PDF]
I personally met the speaker when he came to KL in 2009, but of course the discussion was not whether he's using Beamer or not. It's just a tool :)
