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!

Open Source: Power and the Passion

I was very lucky to present this talk a few times: at RubyNation in Arlington VA, USA, June 2016, at Deccan RubyConf in Pune, India, August 2016, at RubyConf Portugal in Braga, Portugal, October 2016, and at RubyConf AU in Melbourne, Australia, February 2017. The video above is from the last of those.

Presented at Trampoline in Melbourne, February 2015.

The Golden Age of the Internet

Presented at RubyConf AU in Sydney, February 2014,
and Golden Gate Ruby Conference in San Francisco, September 2014.

The C Word

Never liked the title - if I had the chance to do this talk again, I'd rename it to Refactoring Community.
