From Concurrent to Parallel

As core counts continue to increase, how we exploit hardware parallelism in practice shifts from concurrency — using more cores to handle more user requests — to parallelism — using more cores to solve data-intensive problems faster. This talk will explore the different goals, tools, and techniques involved between these various approaches, and how to analyze a computation for potential parallelism, with specific attention to the parallel stream library in Java.

Real World Java 9

The feature we always hear about whenever Java 9 is in the news is Jigsaw (or modularity). But this doesn't scratch the same developer itch that Java 8's lambdas and streams did, and we're left with a vague sensation that the next version might not be that interesting. Java 9 actually has a lot...

Using FlameGraphs To Illuminate The JVM

FlameGraphs offer us a new way to visualize execution profiles, combined with Linux system profiler perf and the recently added -XX:+PreserveFramePointer option in JDK 8u60 we now have for the first time a way to capture a comprehensive profile for the OS, JVM and your Java code. In this...

Event Sourcing on the JVM

Have you ever wondered about event sourced systems and how they work? How to structure things around a transaction log yet still keep the system stable over time when change arises. In this talk we will look at Event Sourcing as a concept as well as specific JVM based implementations that are...
