David R. MacIver
David is a long time PyCon UK speaker. Past talks include one about Hypothesis, a neat testing library that you should all be using, successfully trolling the PyCon UK organizers into using linear programming for scheduling, and a keynote introducing 800ish Python programmers to anarchist social theories. He's not very good at taking talks, or biographies, seriously, but somehow he keeps getting allowed back and people keep attending his talks anyway.
You are a robot tasked with mapping a maze, but a lot of these rooms look weirdly similar. What do you do? A light hearted introduction to some neat algorithms.
