I'm hoping to run at least one cyber-dojo as a birds-of-a-feather session at the upcoming accu conference. cyber-dojo allows you to perform code-katas using a web browser front end. To make sure it all works as planned I connected a client and a server together via a switch+router. It came together fairly painlessly! cyber-dojo is written in ruby and rails served by passenger and apache2 all running in an Ubuntu VirtualBox inside the MacBook on the right. The client on the left is Firefox on an MSI netbook also running Ubuntu.
