Raspberry Pi is a quite powerful, versatile board and it offers a lot for the $35 price. I bought & configured one for a NAS + miniDLNA server and it works surprisingly well.

As a presenter at Timisoara .NET Meetup #2 I thought it would be interesting to share with the local community some of my experience with a not so known technology from the .NET stack: Windows Workflow Foundation. For this purpose, I built a demo app (source code available on github) and a short introductory presentation for the topic.
