Fractions of an acre.

The house is almost entirely unpacked. All that remains is the office, which is a big mess, and half of the garage, which is filled with empty boxes. I haven't bothered to set up the office since Comcast is seriously dragging their feet on our internet service. It's kind of sad that I don't feel much need to set up the computer in the absence of connectivity.

Emma's first birthday party was Sunday, and we had a bunch of people over. (Well, about 14 people, but that's a lot for us.) One person saw our back yard and said "Whoah, it's like I'm back in the midwest!" That was either hyperbole or a very bad memory. Ours is a very nice yard by the standards of this area, but it's nothing compared to elsewhere. The bay area has lots of ways of distorting your perception, and this is one of them.

Five fingers, five binary digits, 0-31. Obviously.

Not normally the kind of thing I go for, and quite a bit later than everyone else, but I finally got around to taking The Geek Test. Some friends of mine scored in the 30's and 40's, so I figured I should find out where I fall.

I'm at 23.27416%: Geek. I scored high in the computer-heavy sections, but a lot of the rest was left blank. A few random things like "I watch documentaries" and "I've read [Asimov/Lovecraft/Tolkien]" and "I've studied a language on my own."

'Course, there was only one check-box next to "I program." I suspect that, if I could put the appropriate number of checks next to that, I'd score much higher.

And they didn't even include "I have a weblog", "I've written my own weblog framework", or "I've created a programming language specifically for web programming", all of which should rightly cast me into the bowels of Pathetic Geek Hell.

Unless "I'm married" and "I have a kid" can reduce your score. Dunno.

Ah, homeownershiphood.

I've discovered a surefire way to make it rain. All I have to do is move.

Earlier this year we moved from a one bedroom apartment to a two bedroom apartment in the same complex. We asked two friends to help, and they generously obliged. On moving day, it rained.

This past weekend, we moved into our new house. We had scheduled a truck and one of the aforementioned friends to help us move. On the day (Saturday), it rained. A lot. We moved quickly, though, dodging raindrops, so there's no water damage to speak of.

The funny thing is that it doesn't rain very often around here.

Anyway, we're sleeping at the new house now. We're still battling to get phone service hooked up, which is worrisome since we have all sorts of deliveries and service installations coming in the next few days. Plus we need to hire an electrician to deal with crappy wiring and pest control to deal with minor dryrot and some engineers to do seismic retrofitting (all of which which we knew about when we bought). Plus we should figure out what's up with the garage door (it doesn't open consistently).

On the plus side, the baby seems to love the new house, and has had no trouble adapting. 'Course, maybe she just thinks we're on vacation and is expecting to return "home" soon. Or maybe she's too distracted by all the boxes and general disarray, and the fact that her parents are too busy to say "Emma, don't climb on the pile of CD's, DVD's, VHS tapes, and casettes! Stop throwing them on the tile floor, I don't care how cool the sound is." It's like a field day for her.

Plus the stairs. She loves the stairs. And she's surprisingly good at using them, for somebody who can't even walk consistenly yet. We still stand nearby as she goes up and down, but we pretty much never have to intervene. Survival instinct: check.

It's a good thing you happened to hire them, then!

It's a month old and has been covered elsewhere, but this quote can't get too much coverage:

"The best way to get the news is from objective sources. And the most objective sources I have are people on my staff who tell me what's happening in the world."

An ugly blue tarp, as seen from space.

I'm a big fan of aerial and satellite photography, and was thrilled to discover the original TerraServer several years ago. Though its datasets are black and white and a bit dated, it's still amazing to see familiar areas as photographed from above.

There's now another site called TerraServer, with more recent datasets, including some in higher resolution and color. I'm not sure if it's a successor to the old one or a competitor, but this one offers access to very high resolution data (1 foot in some areas) for a fee. Still the same basic interface, though: web form that lets you search for an address and then click to pan or zoom.

It occured to me that the web is hardly the optimal platform for applications like this. (I happen to believe that it's not the optimal plaform for any application, but that's another discussion.) Specifically, I suspected that a local application could let you zoom and pan smoothly over datasets like this, by fetching image tiles on demand from a server. It's such an obvious idea, I figured somebody must have done it.

Turns out I was right.

I asked a friend of mine if he knew of such an application, and it he grinned. "I worked on one once." TerraVision is a cool open source app that does exactly what I expected: it lets you browse multiresolution image/elevation datasets on the earth interactively. You can load more than one dataset, to provide coarse data over a large region, and more detailed data in specific areas. It all works in a small memory overhead by managing a multiresolution cache of tiles.
TerraVision can fetch tiles on demand from a server or operate from datasets on the local disk. Unfortunately, there don't seem to be any active TerraVision servers out there, so you're left to download the handful of datasets they provide (or convert your own from USGS data.) In the bay area, for example, I was only able to browse 25 meter terrain data, which isn't enough to resolve individual houses. Still, very cool, especially for an open source app.
Kiril also pointed me to a more polished commercial app that does the same thing. Last night I tried a free 7 day trial of Keyhole LT, and was blown away. Because it's a commercial app, they provide a server with really high resolution data over most major cities, and coarser (but decent) data elsewhere. If you live anywhere near a major city, you can probably zoom in to see your house.
Keyhole also lets you do address queries (like MapQuest), which makes it easy to find familiar places. I spent several hours last night exploring all the places I've been, continually amazed at the detail in their dataset.
For example, the house we just bought is easily discernable in Keyhole. In fact, behind the house there's a bright blue rectangle, which I realized is the blue tarp on top of the awning in the back yard. As seen from space!
If you have a Windows machine with any half-decent graphics hardware I highly recommend you check out Keyhole LT. (It works on my laptop with Intel i815e, so it'll probably work on your computer too.) Find your house. You'll thank me for it.

Mi casa es mi casa.



Things are finally falling into place. We made an offer on a house two weeks ago, and only now are we done with inspections. Things were touch-and-go for a while because inspection did turn up a zombie infestation.



Well, not zombies, but still something creepy. In the crawlspace under the house, our inspector noted an unusually thick layer of efflorescence (salt deposit). That's a sign of moisture leaching out of concrete (or in our case soil), evaporating, and leaving mineral deposits behind. A little efflorescence is common in basements the world over, but this is a thick layer. Two inches deep in some places. We were concerned that it represented a serious drainage problem under the house, or an adverse condition of the soil.



Some other issues came up as well, and we ended up extending the inspection period so we could bring out some specialists. Things were stressful for a while, but as of last night all of the issues have been resolved. The house, its foundation, and the supporting soil appear to be in great shape, so we're going through with it. We'll close escrow on October 30th, and move in soon thereafter. We're psyched.



The pictures at the right are of the front, back, and two shots of the backyard. These were taken during the general inspection (hence the ladders), and so the cars and paraphernelia are not ours. The house is 4 bedrooms, 3 baths, 2-car garage, 1867 sq. ft.



(For the curious: the soil expert says the house was built in the wettest year ever, and the moisture probably worked its way out over the next season or two. Though he's "never seen anything like it", he claims it's of academic interest and little else. Whew.)

Insert Arnold Joke Here.

Ack! While I wasn't paying attention California flipped out and elected Arnold as Governor! At least, that's CNN's projection, already reported as fact. (I actually was paying attention: I voted today, even though we're in the midst of house inspection hell.)

My only hope is that Arnie is as socially liberal as he claims. The pundits claim he'd never survive the scrutiny of the right wing in the primary of a normal election. That gives me some hope.

As for fiscal policy, it's mostly voodoo to me. Lowering taxes and spending pretend money doesn't sit well with me, but since I'm one of the ones that benefits (in the short term, at least) from lower taxes, I'd love to be proven wrong. Plus, I have no choice--Bush is already doing it to us.

Serve us well, Mr. Schwarzenegger.
