Data At The Speed Of Life – Reactive IoT Applications in Scala with Angular2

I had recently come off of a three year contract and found myself with some time on my hands. I was interested in working on an application that interfaced directly with some sort of small device. The director of our company, Don Coleman, had done a good bit of work with small devices so I spoke to him about the possibility of building a small application around those devices. He agreed to it and offered to assist from the hardware end. Our director of training, Ken Rimple, was researching the Angular 2 JavaScript framework at the time and offered to build the UI for the application. We eventually decided that we would build a demo to display at our booth at the 2016 South by SouthWest conference. This post explains our approach and some lessons learned.

ETE 2015 – Ben Christensen – Applying Reactive Programming to Existing Applications

This talk will leverage the experience of introducing reactive programming into existing imperative, blocking codebases to demonstrate how it can be done and when it can make sense to do so. Not all benefits of reactive programming can be obtained without a greenfield, fully async architecture, but many can. Subjects to be covered will include the mental shift from imperative to declarative, working with blocking IO such as JDBC and RPC, service composition, debugging and unit testing.

Philly ETE 2014 – Jan Machacek – Reactive APIs With Spray

Learn the components of Spray, how they build on each other to offer convenient abstractions, and how you can easily combine the different abstraction levels in your code. Jan will show how Spray makes the implementation of even complex APIs easy and understandable.

Order Out Of Chaos – Maintaining ordered processing of messages in AKKA actors

The reactive paradigm is a wonderful thing. The basic idea is that a reactive application, as much as possible, is asynchronous from beginning to end. It should be event driven, fault tolerant, scalable and responsive. Writing an asynchronous application, however, has it’s own set of unique challenges. In this post I’ll demonstrate an approach we took to solve the challenge of maintaining a definite order, specifically when performing database updates in asynchronous code within an actor.

DevNews #68 – Clouds and Androids abound, reactive ones!

With a week of the gang has a lot to talk about, from reactive programming in Javascript with Bacon.js, to the failure of a startup (so long, and best of luck to the EverPix team, we loved your service) to the brain drain in academia due to data science, to some nitty gritty Javascript, a new reactive project in Spring, we got it all. Don’t forget to post us on the LifeHacker favorite podcasts page!
