Please RSVP on OUDL's Meetup page.
This is the scaling talk you've been waiting for.
Folks have been asking for it on UserVoice, so come and get it. Yongwen Xu and George Lee have volunteered to share their experiences scaling web applications using Heroku.
This is part of the UH Hackathon prep schedule, but the attendance is open to OUDL members as well.
Like I said, the scaling talk you're looking for.
