Math is hard, let's... well, let's talk about math. Interesting and mind-tickling talk!
Let's do math in stead of PHP, but in the end you walk away with tons of ideas to try with your own projects!
Very interesting talk with some nice eye openers. Joshua invites the audience for active interaction to hold everyones attention.
It was quiet allover the evening, so people where really thinking about the things.
Would recommend to every developer who's starting with Unittests to visit this talk to open your state of mind.
