Jafar Husain's ACM keynote presents Netflix's JSON Graph and Falcor, which let web developers treat all cloud data as one virtual JSON model. It combines reactive programming with REST principles.

David Nolen presents Om Next, the redesign of the ClojureScript Om library, drawing on Relay, Netflix's JSONGraph and Datomic. He covers the tradeoffs in handling the client-server boundary over immutable data.

A talk by Yuri Iozzelli at a WebAssembly meetup on CheerpX, an x86 virtual machine running in the browser. It uses a JIT compiler that emits WebAssembly at runtime to run real native applications. It covers the architecture and demos such as porting a multiplayer C++ game.
