What's it about?

Today is about shooting for code perfection, not results & output.
  • 5 sessions
  • Same exercise, different constraints
  • Pair programming
  • Retrospectives at end of each session
  • It's a day for you, constraints are just a guide

The rules

  1. Delete your code at the end of each session
  2. No really, do #1

Conway's Game of Life

  1. Live cell && live neighbours <2 -> die
