Those PHP developers that live around the Columbia, MD area might want to drop in to the PHP user group meeting that Theo Schlossnagle mentions on his blog today:
Just a friendly reminder that we'll be having our first meetup [on 05.14.2008] as planned. I thought as a good kick-off we could all collaboratively share what we do with PostgreSQL. We'll start off with a whirlwind tour of how OmniTI uses PotsgreSQL, taking a brief look at ZFS, DTrace and large datasets.
The event will be happening here and will start at about 6:30pm.
