Functional Reactive Programming with RxJava • Ben Christensen • GOTO 2013 

One of the best presentations on this topic; especially if you are getting started on RxJava

I've recently been learning RxJs and this presentation was almost entirely applicable to me. I love that these concepts cross language barriers.

One of the best rxjava usage example :)

Very helpful presentation, thank you!

Very good talk, thanks for sharing!

Great presentation!

Great presentation to watch to start my day. :)

Great talk, thx to share !!

What are vector and scalar response mentioned at @15.000?

Strange, the talk is about rxjava, but the examples are in the unused groovy language. There are 5% of java devs using groovy.

Why are all the examples in Groovy vs simply Java? This is RxJava after all but finding actual Java usage is proving to be difficult.

compose functions in a reactive manner - you can take a flow of data, transform it as they asynchronously flow through the system and more interestingly combine them together functional - lambdas, closures, mostly pure, composable (similar to IO monad in haskell) reactive - asynchronous, values, events, push rxJava - a library for composing asynchronous and event-based programs using observable sequences Netflix reached the limit of RESTful API (generic, optimized for nobody) one network request instead of many to minimize network latency, client logic pushed to the server nested logic on the server needs to be done concurrently to be performant enough allow anybody to create endpoints owner of the API should retain control of concurrency behavior rx enhancement to observer pattern (from imperative synchronous to declarative asynchronous) observable allows to achieve higher order functions for transformation and composition on both vectors and scalars implementation details are abstracted away from how data is consumed (client treats all operations as async but implementation can decide whether it is blocking or what resources it uses) marble diagrams - a visual representation how data is flowing reactive programming can be thought as pipes of data flowing together with HOF as connectors

Am I the only one who's wondering what was that 'bracket bird' question about?
