Adding a Feature to TalkingPuffin

This video is different from the other instructional videos in the Young Programmers Podcast, in that it doesn’t teach step-by-step how to do something. Rather, it shows a professional programmer making an improvement to a real product. The product here is TalkingPuffin, an open source Twitter client written in Scala. Dave Briccetti adds a new feature that allows filtering out tweets (messages) from people not following the user. Inexperienced programmers are not expected to understand everything shown. The point is just to see a professional programmer at work, using great tools and a great programming language.
