LISA has often conflicted with my birthday but not this year. That doesn't mean I can't be tempted into throwing a party, but I think I'd rather just attend the BoF (Birds of a Feather) sessions at night.
What is a BoF? Suppose you are really interested in a particular topic: CFEngine, Ubuntu, TCP/IP on 8-bit computers, system administration at companies with non-English speaking users, etc. You can sign up for a 1-hour timeslot and gather people to talk about it.
BoFs are one of the absolute best ways to make connections at LISA. This is a very valuable service.
There are many timeslots and many rooms available. Some people pre-register their topic, others wait until the last minute. The list of pre-registered BoFs is online here. (Oh, and some BoFs are officially sponsored by vendors. You can guess which one I'll be involved with.)
This year's conference is in San Jose, so all my silly-cone valley friends should have no excuse. See you there!
