Show HN: Free Java Lambdas Screencasts

I got back in to Java a last year for work and was really pleased by some of the features added in Java 8. I decided to make a screencast series covering some of the new features (lambdas, streams, etc) and have finished the first section on Lambdas: http://bitpress.io/learning-modern-java/

As I said, I have been out of the Java world a while, since college in fact, so I would love some feedback on these screencasts (if you don't want to download the zip with the videos and code samples, there is a preview chapter under "What's Inside"). You can also sign up to get announcements about other screencasts my partner and I are doing (we are covering PHP, APIs, Docker, Java, and more)

I am currently in the process of recording a direct follow up to these screencasts covering Java 8 Streams and will send out an announcement via newsletter, so sign up if you are interested!

Thanks for your time!
