I attended the Software Development Summit December 2013 in Helsinki.
I was fortunate in being asked to perform a keynote, and asked to fill in for a keynote speaker who unfortunately couldn’t attend, so I did two keynotes. Lucky me.
You can find slides for the talks listed over on my Compendium Developments site.
I did receive a pointer to FreeNest - an open source platform put together by students which is designed to help teams get up to speed with a set of collaboration tools on Ubuntu quickly.
The only downside I had was that I had to miss Gojko’s Keynote because I thought I was flying out early. Of course the London Fog had other ideas so instead of learning from Gojko, I was stuck at the airport instead of enjoying the end of the conference :).
