I have continued working through the Programming Phoenix book.

Currently I am at the end of Chapter 10.
This has introduced using websockets in Phoenix to interact with the page.
The application allows annotations to be made to a video that playback in real time.
I am having some trouble with the actual Youtube API since it now complains about cookies not being on the main site. I intend to finish working through the book and return to fix this issue.
Chapter 11 is about refactoring the application to use an Umbrella Application. This will split the Rumbl and RumblWeb applications apart. Having a real demo of refactoring is useful.
