The OPEN 2010 conference was very well organized and had many interesting talks.
The side of low level, infrastructure things was presented by people from Red Hat, VMWare and IBM. The buzz words "SaaS", "PaaS" and the likes were all over the place together with recent hot topic of virtualization.
On the application level there were interesting presentations about Django, PostgreSQL. And of course our own presentations on Ruby, Rails, NoSQL along with a longer, 2 hours "Introduction to Ruby" workshop.
