If you know Manning, you'll know us as a publisher of high quality technical books. We've tried to bring some of the experience of books to video though. Primarily wanted to make it easier to navigate than having to scrub across a 10 minute video to find what you want by allowing you to click on the transcript to get to exactly the topic you're interested in. We also have support for executable code in almost any language, right in your browser, as well as quiz-questions to help you make sure you get what you're learning.
