Sean Cribbs will be previewing his presentation for QCon New York entitled "Membership, Dissemination and Population Protocols" (https://qconnewyork.com/ny2016/speakers/sean-cribbs). Sean has extensive experience in distributed systems as well as Erlang and Elixir, so this could be a really enlightening talk for anyone who hasn't taken advantage of Elixir's (and Erlang's) parallel and distributed nature.
Sean's talk will be a bit advanced and/or architectural, so we'd also like to see if anyone else would be willing to present a more "introductory talk" as well? Or, if you're not ready to speak, propose ideas for presentations and we'll see if anyone else can speak about it!
I might suggest on a talk on tail optimizing functions, which might be preceded by talking about Elixir's idea of lists and how they're created/handled.
Also, a talk on ExUnit might be good.
Any other ideas?
