This talk will provide an overview of several Java 8 features including lambdas, default interface methods, and the Date/Time API. It will also cover reactive programming, CQRS, event sourcing, and front-end technologies like AngularJS. The talk aims to inform the audience about these topics at a high level without going into depth on any single topic, and will include discussions, Q&A, and pizza.
