Initially begun as an internal Scala conference, the organizers opened the conference this year to external folks interested in Scala. I learned a lot from this event, gaining perspective on trends in the Scala community and sparking curiosity in several interesting applications of the Scala language.

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. … Read More
This is a continuation of my Internet of Things with Scala posting. In this installment I will go over the assembly of the device that will be used to capture the soil moisture data and send it to an MQTT broker so that it may be picked up by the Scala/Akka based application. The Parts … Read More
