Most of you still have one final presentation. Try to make it crisp and clear. Take it as your goal to teach the class enough about the system you are explaining so that they could develop a simple application on their own. That means that you have to explain both the overall framework that the system you are discussing offers along with enough of the details so that someone can get started with it on their own.

Since we have quite a few people still to go we will have to be quite strict on time. I'll minimize my interruptions but will hold you to a limit of 25 minutes.
