Every time I run a cyber-dojo I learn new things. And new ways to make it simpler. For example in Olve's cyber-dojo one player had to leave early and one of the laptops was their laptop. In a normal code-dojo that would be a problem. But in a cyber-dojo it's not an issue. You just fire up another laptop and carry on where it left off.
Olve also invented a much simpler way to do the musical chairs. Instead of having one timer to rotate the keyboard driver within each group and another timer to shuffle the groups we now have just one timer. When it dings the keyboard drivers in each group have to get up and find a new group - which they then join in a non-driver role. Much simpler!
