In this episode I talk with Riccardo Carlesso, Google developer advocate and co-founder of Rubycon, a Ruby conference held in Rimini, Italy in May 2026. Riccardo explains how a joke about PyCon became the conference's name.

In this episode I talk with Travis Dockter, organizer of Blastoff Rails in Albuquerque. When Sin City Ruby and RailsConf both ended, Travis decided to start his own conference.

Roy explains how its first customers came from co-founder Thijs biking around Amsterdam, why usability was the big selling point, and why aiming for "80% of what competitors have" works. We also talk about brand marketing for small companies: sponsoring conferences like Rails World, ha...
