It depends...

• Using https://cyber-dojo.org in a commercial organization requires a licence.
• Non-commercial use is free, but please
  
• 100% of the licence fees and donations help children learn about software.
• The cyber-dojo Foundation is a Scottish Charitable Incorporated Organisation.

It's up to you!

• Large companies/organizations typically pay ~ £1000.
• Smaller teams/individuals, less.

That's also up to you!

• You can pay a larger amount once.
• You can pay a smaller amount every year.

There are two ways:

• Email license@cyber-dojo.org with much you would like to pay, and how often.
• 
  If you would like a license document, email license@cyber-dojo.org.
• Thank you.

They are generously paid by our sponsors:

• Praqma, Cucumber Limited, and CodeEntropy.
• If you are interested in being a sponsor, please email sponsor@cyber-dojo.org

Two reasons:

• To provide identity without requiring a login.
• To provide anonymity during reviews.

Yes. The repositories are split across four github organizations:

• cyber-dojo-languages holds the Dockerfiles for the images where the tests run.
• cyber-dojo holds the microservices for the server.
• cyber-dojo-tools holds custom tools.

Yes. Instructions and scripts for running on...

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.
