I spoke about memcached. I tried to dig a bit deeper into how memcached works. On the mailing list we get a lot of new people that make assumptions about memcached. Most talks I have seen focus on why caching is good, how to use memcached, the performance gain. I kind of assumed everyone knew that stuff already. I guess you could say I gave a talk that was the real FAQs of the project.
Here are the slides. Derick Rethans took video of the talk. When he gets that online I will add it to this post.
