I’ve previously written about Snappy and Unity 8’s Snappy Scope, back when I was first getting started on it. Since then, both the scope and Ubuntu Core itself have come a long way, so I thought it was time for an update and a quick demo.

I started on the GUI first, writing a server that received object locations and handed them off to the GUI which displayed them in a nifty way. I was using Qt and QML, which I have used in numerous personal projects, so I was pretty familiar and confident with what I was doing....
