Session 1: The Joy of Functional Programming
It's been around for a long time, but everyone's talking about it all of a sudden. But why and why now? We've been programming in languages like Java for a while, quite well. Now we're asked to change and the languages themselves are changing towards this style of programming. In this keynote, a passionate polyglot programmer and author of _Functional Programming in Java: Harnessing the Power of Java 8 Lambda Expressions_ will share the reasons we need to make the paradigm shift and the pure joy, the benefits, we will reap from it.

Session 2: The Power and Perils of Parallel Streams
If streams can be parallel, why not make them parallel all the time?—is a common question from developers getting introduced to Java 8 streams. In this talk we'll take on three separate topics. 1. When to consider parallelization and when not to. 2. How to parallelize, how to decide on number of threads, and how to control the threads pool. 3. Learn about some common mistakes people make when using parallel streams. The goal of this talk is for us to learn when and how to make good use of parallel streams.
