Ruby on Rails talent at the Palmetto Open Source Conference It is no secret, there is going to be a lot of Ruby on Rails talent at the Palmetto Open Source Conference this year. This is no coincidence, the Ruby on Rails ecosystem helps define the collective focus of the invited speakers for POSSCON. Each one of the speakers, know for their contributions to the Rails community has had a broader reach in regards to web development in general, and specifically, the ecosystem in which Rails exists.
