This document discusses test-driven development (TDD) coding practices using the dojo method. It introduces concepts like the Shu-Ha-Ri learning stages, legacy code without tests, and test-driven practices like red-green-refactor. Specific examples covered include the bowling game kata, Conway's Game of Life simulation, and randori pair programming. Links are provided to online resources for further information.

11. Rules
• Any live cell with fewer than two live neighbours
dies, as if caused by under-population.
• Any live cell with two or three live neighbours
lives on to the next generation.
• Any live cell with more than three live neighbours
dies, as if by over-population.
• Any dead cell with exactly three live neighbours
becomes a live cell, as if by reproduction.

12. Randori
• Two people at a time
• One person at keyboard
• The other assists
• Every 5 minutes keyboarder moves off,
assister goes to keyboard, new person assists
