魔法少女プリティジューリャ

Let's see, there's "Fourth of Juplaya", Toorcamp (kinda late to go now), Anthrocon, "Skeleton Key: A Steampunk Cabaret", a rave somewhere, and a party at veedub's. What else am I missing?

Completely unrelated, a friend of mine's startup needs to hire a backbone networking person. Someone who know about BGP, and how to diagnose major network problems, and knows who to call at what providers to get things fixed. You don't have to be in the bay area for this one.

I don't have time to format this into a table and stuff.

I just now realized that Black Hat Europe and CodeCon overlap.

So that I don't forget…

Stuff going on this weekend:
The Alternative Press Expo
The California Steampunk Convention
Reclaiming's 29th Annual Spiral Dance

So, here's my current plan:

Fly out to Baltimore on Oct 18, rent a car and drive up to Connecticut.
Spend the next few days with my old girlfriend.
Around Oct 23 or 24 (Thursday or Friday) Drive back down to the DC area and visit people.
Attend wedding on Oct 25.
Oct. 26: Return car, and jump on plane for California.

If you are anywhere near Connecticut or the Washington DC area, and you would like to see me, please tell me now.

Gotta get organized…
12:00-20:00 Market & 2nd St. San Francisco Love Fest
14:00-14:45 Mission Dolores Park Mp3 Experiment San Francisco
14:00-23:00 345 Spear St. SuperHappyDevHouse
20:00-? Party at nasu_dengaku's house.
Outside San Francisco:
10:00-18:00 Hollister, CA Ren Faire
00:00-23:59 San Jose, CA Silicon

And then a bunch of parties like this one.

So, 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:

• 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.

Ok, so, what am I forgetting? I'm deliberately not going to bring a tent this year, as every single year I set one up — and then never sleep in it.

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.

Ok, so I can jump on a plane tonight or tomorrow and fly out to GAIAN MIND SUMMER FESTIVAL. If I was going to drive out, I'd have needed to have already started two days ago — and I don't have the time with crazy work deadlines. I've been dithering on going so much, that plane tickets are now about ~$600 to the DC area, and ~$700 to the Pittsburgh area. Plus $145 for registration; and ~$100 for a rental car or something. Also, the site where the event is held, also seems to have an outbreak of the Norwalk virus or something, so I just have to do the burner-thing of bringing all of my drinking and washing/bathing water onto the site with me. And I'm still kinda a tiny bit ill from this whatever I've had for the last two weeks.

…Not that any of this has ever stopped me…

If I took next week off, I could visit friends on the East Coast, and then go to Anthrocon next weekend. (Which means that I'd miss San Francisco LGBT Pride.) If I fly back Sunday or Monday, that only really gives me a day or two at Gaian Mind, and an almost equal amount of time sitting on airplanes or driving around. Which is not very relaxing.

I can't really telecommute right now, because I'm currently building another server farm at work (it's a small simulation of the Internet.) So I'd get another week behind on stuff at work.

If I stay in the Bay Area, there are several parties I could attend:
feyandstrange and digitalsidhe's Housewarming party (Sat. Jun 21 19:00-)
Kallisticon, and tyrsalvia and metaphorge's Housecooling party (Sat. Jun 21 21:00-)
veleda's Solstice ritual, and Burning Man thingy, the web site is down, it's supposed to be here: http://www.temple08.com/AwakeningSun.html And the party is apparently on (Fri. Jun 20 19:30-)
And then veedub is teaching a class on Feri tomorrow (Fri Jun 20 19:00-), and wants me to show up to help teach the newbies.

I think that's it… other than the zillions of other things in my personal life I have to attend to.

This version contains a lot of info that I found on fliers at Pantheacon. No, I'm really no going to all of these.
