Futureboard, a Flipboard-like Scala Futures demo

I’ll write more about this shortly, but yesterday I created a little video of a demo application I call Futureboard. It’s a Scala/Swing application, but it works like Flipboard in that it updates a number of panels — in this case Java JInternalFrames — simultaneously every time you ask it to update.

The “update” process works by creating Scala futures, one for each internal frame. When you select File>Update, a Future is created for each news source, and then simultaneous calls are made to each news source, and their frames are updated when the data returns. (Remember that Futures are good for one-shot, “handle this relatively slow and potentially long-running computation, and call me back with a result when you’re done” uses.)

Here’s the two-minute demo video:
