What is a Dojo Day? Rooted in the Software Craftsmanship principles of repeated, deliberate practice, this will be a day of coding exercises in your language of choice to enhance your software development skills. It will be a great way to experience Pair Programming and different forms of Test-Driven Development (TDD).

Coding kata are derived from the idea of martial arts kata: a slow series of movements that when repeated sufficient times instill "muscle memory". Coding kata are simply-stated, interesting exercises such as a Ten-Pin Bowling Game, calculating Prime Factors, or converting a number to Roman numerals that instill "coding memory" to practice and improve your skills in TDD, object orientation, solution design and implementation.

The day will run a number of sessions of roughly 90-minutes each focussing on a different exercise. Each exercise will be completed in pairs. Please bring a laptop.

UPDATE: Please note the change in venue. Many thanks to Granta Design Ltd. ( for volunteering to host this event!
