Simply explained: Akka Streams Backpressure

|

Backpressure Food for thought Very simply put, the idea behind backpressure is the ability to say "hey slow down!". Let's start with an example that has nothing to do with software: Imagine you own a factory that produces doughnuts (lucky you!) and just signed a contract with the largest grocery chain in the Northeast US. To increase output, you decided to overhaul your existing factory and open a new one. Late Monday evening you get a text "Emergency! Get to…

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.
