Last week, I attended a DevNation talk, “Getting Started with C# on Red Hat Enterprise Linux and OpenShift”, given by Scott Hunter from Microsoft. The first thing Scott asked was, “Does anyone know how to recover from hitting CTRL-ALT-F8 in Red Hat Enterprise Linux?”

At DevNation, Red Hat’s Galder Zamarreño gave a talk with a live demo, Building reactive applications with Node.js and Red Hat JBoss Data Grid. The demo consisted of building an event-based three tier web application using JBoss Data Grid (JDG) as the data layer, an event manager running on Node.js, and a web client. Recently, support for Node.js clients was added to JDG, opening up the performance of a horizontally scalable in-memory data grid, to reactive web and mobile applications.

On Tuesday night at DevNation, Eurotech sponsored an evening of IoT hacking. The object was to create a laser tag-style game. Participants were given a TI SimpleLink SensorTag development kit and a laser pointer. The sensors use Bluetooth Low-Energy (BLE) to communicate with the Eurotech IoT gateway running Red Hat Enterprise Linux.

At DevNation, Red Hat developer Henryk Konsek, gave a talk on an open source gateway for Internet of Things (IoT), using Apache Camel, Eclipse Kura, Much of the focus of the talk was on the scalability needed when IoT is really embraced by organizations. The key take away from the talk is that IoT in reality is all about messaging. Successful implementations will rely on the things we’ve already learned from Enterprise Integration Patterns (EIP).

Red Hat’s Peter Larsen, the OpenShift Domain Architect, gave a talk at DevNation, “Developing on OpenShift without the build waits”. Developing with the OpenShift Platform-as-a-Service can be very compelling: developing and deploying software without having to worry about the infrastructure. When you first try OpenShift, it’s quite impressive to see how easy it is to develop and deploy software using the built-in templates that include preconfigured components such as databases and application servers. This allows developers to start coding right away.
