SCALE

https://www.socallinuxexpo.org/scale/23x

Just a heads up, we are the largest open source conference in North America completely community run and only 2nd to All Things Open, (which can get 5-6k audience and is not completely community run). If you are looking for community that lives and breathes open source, this is the place to be. Turning down the spot after being accepted would likely keep you off the speaker list moving forward.
