A good overview. Some of the practical applications felt a little theoretical, but the core concepts were explained well. Overall, a positive learning experience.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.
