The FOSS4G (Free and Open Software for Geospatial) conference is currently happening in Portland, OR.  They’ll be live streaming all the keynotes and sessions 9/10-11 if you see any of interest.

FOSS4G is a pretty awesome organization, and the conference usually features at least a few really cool projects plus introductions to the latest and greatest tools of open source GIS.  Check out their schedule at https://2014.foss4g.org/schedule/sessions/
