Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design.
Coderetreat is our chance to practice outside of work constraints.
Day format Intro (15 min) - We are doing it now 3 sessions Nice long lunch 2 sessions If you have enough energy - one additional session Closing circle
Delete your code!
For each session Find a new pair partner! Avoid pairing with colleagues you work daily It is advisable to try other languages. But one in the pair should be experienced with chosen language Do not try to finish the problem Focus on practicing
Four Rules of Simple Design / TDD cycle Passes the tests No duplication Reveals intention Fewest elements Write a failing test (make it red) Write minimal amount of code to pass it (make it green) Refactor - improve design without changing functionality
Game of Life 1. Any live cell with fewer than two live neighbours dies, as if caused by under- population. 2. Any live cell with two or three live neighbours lives on to the next generation. 3. Any live cell with more than three live neighbours dies, as if by over- population. 4. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
We are here to have fun - be awesome to each other
Closing Circle What, if anything, did you learn today? What, if anything, surprised you today? What, if anything, will you do differently in the future?
