I've been doing as many tutorials for BB10 as I can find. The very best I've come across so far?

This tutorial builds the "Quotes" sample app. Why do I like it? It is long, and detailed, and covers a very broad range of programming concepts, including UI layout and coding in Cascades QML, and C++ coding for business logic and data access.
Done any other good ones? Post them here!
