For those who couldn't join us at the #VotingVillage at #DEFCON33 earlier this month, videos of all the talks are online in this YouTube playlist: https://www.youtube.com/playlist?list=PLltrHIXltfGLotq79TBgIK9QK4O29Z2FF
We had a great program covering a wide range of topics on the theory and practice of US election security.
I'll post a few highlights of more general interest in the thread that follows.
A couple notes: The room audio on the first day was abysmal because the LV Convention Center failed to enable the room speakers. (Sigh.) So if you were there and had trouble hearing, the recorded audio in the videos is much better!
There's an additional talk video in the playlist at the end, provided by a speaker who was unable to obtain a visa to attend in person (double sigh).
These are just a few selected highlights. We had a great (if exhausting) time putting on the Village this year, and we hope you find the program interesting and helpful, whether you joined us in person or online.
