This document outlines the principles and format of coding dojos, which are meetings where programmers practice coding skills together in a collaborative and non-competitive environment. The goals are to continuously learn, teach, and discuss concrete coding problems. Formats include katas, where a presenter demonstrates a solution step-by-step, and randori, where participants take turns pairing on time-boxed coding problems while others observe and provide feedback. Retrospectives are held at the end to discuss learnings and improvements. The aim is to practice skills through failure and redundancy rather than rushing to finish or competing against others.

2. Motivation
Programers don't practice!

3. Background
Kata » Coding Dojo

4. Principles
 Continuous Learning
 Safe environment:
– Non Competitive
– Collaborative
– Inclusive
 Fail & Redundancy
 Baby steps

5. General Rules
 Computer + Projector
 TDD (red » green » refactor)
 Everyone should understand
 ALWAYS
start from
scratch

6. Retrospective
 At the end of all meeting:
– “What did we learned?”
or “What did we liked?”
– “What could have
been better?”
– Discussions or comments

7. Formats
 Kata
– Presentation of a solution
– Everyone should be
able to reproduce
– Interruptions are
allowed at any
moment to ask
questions

8. Formats
 Randori
– Pair Programming
– Time-boxed rounds
– After each round (5-7 min.):
• The co-pilot becomes pilot
• The pilot goes back to the audience
• A new co-pilot is invited from the audience
– Comments and critics only on green
– Silence on red

9. Goals
 Practice
 Learn
 Teach
 Discuss with
CONCRETE
basis

10. Don't...
 Rush to finish the problem
 Use a real problem
 Go into flamewars on discussions
 Compete with other participants
 Allow people to get lost

11. Schedule
 14h00 14h50 Dojo presentation
 15h00 15h20 Problem presentation
 15h20 16h30 Programming
 16h30 17h00 Retrospective
 17h00 ... More programming?
