Pre-Registration for Penguicon will be open until Friday April 8, 2005, and yes if you miss the pre-reg date you can register at the door. Penguicon has a full schedule of Linux and Sci-fi related panels slated for this year so don't miss it (we have panels for everyone from the beginner to the l33t h4x0r). Penguicon will be held on April 22-24, 2005 @ the Novi Sheraton in Novi Michigan." I don't usually plug local stuff, but this show is a truly unique blend of Linux & Scifi and one of my favorites. This will be my third year speaking, and I'm really looking forward to it. I'll post more in my journal as I figure out scheduling. At the very least, we should pack the hotel bar with Slashdot readers for some quality beer time after my session.
