Todd Montgomery talks about the Internet of Things: what it is and is not, looking at languages and protocols that will be useful, concurrency, manual memory management vs GC, and much more. Also: Kaazing's Nuklei project.
Felix Klock II explains concepts of the Rust language: the concurrency model, the type system, allocation and ownership models, the macro system, its style of FP and OOP, and much more.
Francesco Cesarini and Viktor Klang explain the motivation behind the Reactive Manifesto and what exactly it brings to the table. Also: what Erlang and Scala/Akka can learn from each other.
