I'll be speaking at the FutureRuby conference, which will be held in Toronto from July 9-12. If it's anything like last year's RubyFringe conference (also put on by the hard-working Unspace crew) it will be a great time, and anything but your standard tech conference.
I'm looking forward to hearing some great talks and meeting lots of interesting new people (the evening events alone are worth the price of the ticket!).

UPDATE: Here's my talk.
