Hey guys, I am the author of this screencast series. BitPress is a company made up of passionate engineers who also love to teach. We noticed a lot of Java developers struggle with or are not exposed to Lambdas introduced in Java 8, so we decided to make a concise, entertaining, and reasonably priced screencast series on Lambdas. There will be a Streams series following up soon, continuing to cover the awesome new Java 8 features. This has become even more topical with the support for (some) Java 8 features in Android N. We also think non-java developers could benefit from seeing how Lambdas are used conceptually as well. Please let us know if you have any questions or feedback!
