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 of great additions and changes to make development a bit nicer. These features can't be lumped under an umbrella term like Java 8's lambdas and streams, the changes are scattered throughout the APIs and language features that we regularly use.

In this presentation, Trisha shows via live coding:

  • How we can use the new Flow API to utilise Reactive Programming
  • How the improvements to the Streams API make it easier to control real-time streaming data
  • How to the Collections convenience methods simplify code

Along the way, we'll bump into other Java 9 features, including some of the additions to interfaces and changes to deprecation. We’ll see that once you start using Java 9, you can't go back to before.

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...

Thinking Strategically About IoT

Cool? Useful? Disruptor? All of the above? IoT is having an impact on more and more industries. As the cost of instrumenting things and collecting data drops, the possibilities for what we can control and the kind of insights we can gather increase. Not only is IoT hardware cheaper and more...
