Live Webinar: A Playful Introduction to Rx, July 18th

Learning Rx does not have to be boring or painful, working your way through theoretical sermons about esoteric concepts like category theory and duality. Life is too short for that kind of abstract nonsense.

Join us Friday, July 18th, 14:00 – 15:00 GMT (10:00 AM – 11:00 AM EDT), for our free webinar featuring Erik Meijer, A Playful Introduction to Rx.

So what is a better way to spend a hot summer day with an ice-cold drink, or a cold winter night with a piping hot drink, than to learn Rx by writing an awesome platform game? In this talk, I will walk you through many of the features of Rx by way of scripting a friendly bug to run across a lush grassy meadow and jump for the stars. In just a few tens of lines of code, we will leverage operators like ‘map’, ‘flatMap’, ‘filter’, ‘scan’, and many more to react to the keyboard, animate jumps, and perform collision detection. We will even use a test scheduler to make the game run at a speed we determine so we can easily debug and test our game.

We will use RxScala and IntelliJ IDEA to develop the game, but since Rx is language- and platform-agnostic, we’ll show snippets of the same game implemented using RxJs and Rx .NET as well. Of course, all the source code will be available for your entertainment on GitHub.

Once you have mastered elementary game development using Rx, you are more than ready to go on and build reactive, event-driven, scalable, and resilient enterprise systems for your pointy-haired boss. But until then, devs just wanna have fun.

Space is limited, so please register now. There will be an opportunity to ask questions during the webinar.

    I see that the clip has already been published:
    However the clip is private. Is this temporary or will it stay this way?
