This years conference is in a new format, spread over three days with a fourth day of tutorials on the schedule, all at the rather nice Radisson Plaza-Warwick Hotel in Philly, courtesy of my boss' budget here at EnterpriseDB (OK, I'm done with the shameless company plugs :-p ). The schedule includes a good mix of topics with varying levels of technical detail for geeks through IT/IS management.
I'll be presenting a new talk in which I'll describe the infrastructure behind postgresql.org, and how it's managed. If you've not been closely involved in a large Open Source project, you may be surprised at just how much there is - certainly far more than a webserver and mailing lists which are probably the most visible things.
Anyway - I'm speaking on Thursday, so if you can get to Philly, it'd be great to see you there.
