I'll be speaking at the next SoCal Python meetup! http://www.meetup.com/socalpython/events/230329648/ If you want to go, sign up soon, there are only a few spots left.
This talk is mostly about Functional Programming in the Python world. FP is great for testing, but it can be a bit mysterious at times. I highlight the awesomeness of FP, the dangerous bit, and how it is related to Django QuerySets.
I've given this talk a few times, and people always get excited about it. FP is not magic! It's a clean and graceful way to write code.
Here's a link with my previous version's slides, notes, and other references: http://johntellsall.blogspot.com/2014/05/talk-functional-programming-and-django.html
Each time I give a talk I change it up a little or a lot. This time I'll probably add more cat photos.
