Defcon Ride Share
Jul. 28th, 2009 12:40 pmIs anyone driving down to Defcon on Thursday-ish, and going from or through the SF Bay Area? I have a dear close friend who needs a ride down. I'm leaving for Black Hat today, so I can't provide one.
DEFCON 16 [Part 1]
Aug. 13th, 2008 09:46 amA few photos from this weekend. The ones of the clouds are part of a panorama I shot on top of a mountain, at sunset, with a large thunderstorm on the side opposite the sun. It should be awesome looking — it certainly was in person.

Travel Plans
Jul. 24th, 2008 10:20 amSo, Aug 1-3, I'm going to be up in Eugene, OR for Faerieworlds 2008, and then next week, from 08/08/08 to Aug 10 I'll be in Las Vegas, NV for DEFCON 16, I think I'm going to skip Black-Hat this year, cause I'm just not getting enough out of it for the price. (The next time I go, I'll probably be presenting my research.)
And then… Aug 25-Sep 1 is Burning Man!
Back in June, a button got pressed somewhere, and I started to obsess over Burning Man; I was having dreams every night about it for several days in a row. This year I plan on taking it easy, and not building anything big, and not camping with a theme camp, and basically not doing any physical labor, or having any great responsibilities. I'm thinking that my contribution to Burning Man this year will be documenting it through photography.
Stuff to bring:
I'm considering rigging up some kind of plastic covers for my cameras (mostly the lenses), so that they don't get completely impregnated with dust. (If you saw my old D200 you know what I mean.) The D300 body is dust and water-proof, but my 50mm f/1.4 lens isn't — It started making crunching noises when autofocusing by about Wednesday of burn. I saw another photographer on the playa a year or two ago, who had their camera inside a plastic shower cap, with rubber bands around the lens and stuff. The only part exposed was the objective surface of the lens. I might do that.

Stuff to bring:
- Food that doesn't require cooking, and 35 Gal. of water
- Fur coats, furry boots, and brightly colored clothes that I'll never be able to use for anything else again.
- Bicycle(s) and parts.
- Camera gear.
- Goggles and dust masks. (Sunscreen, Lip gloss, garbage bags, etc.)
- Bright blinking flashing glowing things.

I didn't take all of these photos obviously; ![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
buckminst was my surrogate photographer. I probably should have brought my other camera up on stage, for shots from up there too, but oh well...
( I'll take alcohol poisoning for $400... )
