What was the inspiration for cyber-dojo?
In 2009 I (Jon) was consulting in Norway. A user-group organized an evening coding-dojo (in a local pub). An exercise, language, and test-framework was picked, and participants split into teams of about 5 people. After ~90 minutes everyone gathered for a review...
  • two teams had nothing to show since they were still trying to install the language and test-framework (using the pub wifi)
  • the other teams spent a long long long time trying to connect their laptops to the projector (Linux, Mac, & Windows)
I became convinced an online coding-dojo was a worthwhile project
  • practising programming deserves more attention
  • effective development is a team activity
I think there is real benefit not practising in a professional IDE:
  • cyber-dojo is about learning — an IDE about development
  • cyber-dojo is for working together — an IDE typically alone
  • cyber-dojo aims to improve skills — an IDE to finish products
  • cyber-dojo promotes coding & testing — an IDE, mostly coding
  • cyber-dojo helps you work slower — an IDE faster
