I'm one of the organizers of the ArrrrCamp Ruby conference which is taking place on the 1st and 2nd of October in Ghent, Belgium. I wanted to post about our call for proposals which will remain open for another month (until the 21st of June).
We have a focus on technical Ruby talks, but we'll always consider talks on different technologies, motivational or inspirational talks as well. Not all selected talks will be Ruby and not everything will be technical per se.
We have no "official" mentorship program in place, mostly because everyone's needs are so different. That said, if you get in touch we'll help you with anything you need, from giving a guiding hand writing the proposal to talk/slide creation to travel arrangements. If we feel we're not the right people to help out, we'll reach out to people in our community instead.
