Here's a nice talk to end the quarter. It uses Java 8's functional programming capabilities to make certain design patterns much easier to use.

The speaker talks rather fast. You have to listen carefully (or pause the video every once in a while) to keep up. But it's a nice illustration of many of the functional programming ideas we have covered this quarter.

One terminological point: the speaker uses the word reduce for what we have called foldl. Other than that most of the idea carry over fairly directly.
