Highly available ladies, for a fee, at Oracle conferenceLarry Ellison didn't provide escorts for attendees at this week's Oracle OpenWorld at San Francisco's Moscone Center. Well, certainly not for all of them. But with 45,000 geeks — the kind of geeks who can afford Oracle's software — in town, it's bonus week for local working girls. "Jet-setting adventuress" Kimberlee Cline eyed a few obviously scalable women gliding in and out of the W Hotel, a short stiletto strut from the show. Thanks, Kimberlee — and whatever you do, don't say "exponentially" to a DBA unless you're sure it's not more of a step function.
