I've had the privilege to speak at a variety of events - and sometimes these talks are recorded (or I've written up notes) - and then I can list them here. Hopefully they're useful and/or interesting!
Presented at Trampoline in Melbourne, February 2015.
Presented at RubyConf AU in Sydney, February 2014,
and Golden Gate Ruby Conference in San Francisco, September 2014.
Never liked the title - if I had the chance to do this talk again, I'd rename it to Refactoring Community.
