Good article. I like that it was more approachable than a journal paper -- as a developer, I am interested in these kind of algorithms but sometimes I don't even know where to begin searching. And as someone without a math PhD, I appreciate the simplifications and real-world applications.

I don't know what you have planned for the next article in the series, but I would recommend adding code snippets in a language of your choice. I would have liked to see your example implemented in python or ruby to make it more concrete.
