2.5 years ago: My car's check engine light turns on, I have to drive 40 miles early Saturday morning to get it checked out.

Today: My car's check engine light turns on, I drive 3 miles to drop it off during the middle of the day. (and hitch a ride back with destroyerj) Life is good!


My next project: This guy genetic algorithmed his way to a Mona Lisa with translucent polygons, and then this guy did something similar. I like images and especially genetic algorithms. Hopefully will have pretty results soon!

1 - djedi and I were driving home when I heard a noise coming from under the car that quickly got louder. It sounded like something had fallen under the car and we were dragging it along or something. We were slowing down anyway so djedi poked his head out the door to see that the right front tire was quite flat. I pulled over to the side and we got out. Luckily we were less than a mile from home by this point, so regardless we could walk home or whatever. Anyway, djedi gets out the mini compressor that was a present from djedi's family (thanks!) and starts pumping air into it. After like 5 minutes of this, it's pretty clear it's not filling up, and I find a reasonably sized hole in the side. (I tried applying pressure with my finger while it was filling up, but that didn't seem to help)

So, djedi looks in the trunk and finds no spare tire. Ack! So I call AAA (the fact that I have a membership gives me great peace of mind, as I'm not so good with cars), and after they transfer me to the Maryland office (I hadn't changed my address...) she sends a tow truck out. Luckily we remember there's a Firestone just down the road, and they're only open until 7 (it's around 6:40 by now) but I can drop the car off out front.

While we're waiting, we both think it's awfully odd that the car, which definitely came with a spare tire, doesn't have one now, despite the fact that I've never used it or anything, so we go back to the trunk to check. Turns out all the storage is done origami-style - so you fold up some stuff to get to the jack and stuff, but then if you fold it up again there is a spare tire! Whoops. I read the instructions while djedi changes out the tire, which goes pretty smoothly. Just around the time we finish I see a tow truck driving the other way that honks as it goes by, and sure enough it turns around and stops. I explain to the friendly driver that we did in fact have a spare and so we could drive it ourselves :-)

Anyway, djedi walks home to start dinner and I carefully drive over to the Firestone. It's already 7:10 but they're still around finishing up, so I watch some "Jeopardy!" while I wait and finally tell them the situation, drop off the key and jog home. I don't like jogging, but this wasn't a long way and it was really a beautiful day out so I didn't mind.

Afterword: Since the hole was in the side of the tire, I'm getting four new tires. I needed an oil change anyway, so this works out decently. (and I'm not getting a Firestone charge card despite getting halfway through the application before realizing what the guy was trying to sell me...)


2 - Ever since I got my new computer a year and a halfish ago, it's been slow. Not for doing big computations, but for switching between screens, starting up Firefox, etc. World of Warcraft is particularly bad, as I've noticed a couple of times that when I switch away and from it, it's very slow and jerky, and loading new zones takes fooooorever. This made me kinda unhappy, but I had mostly learned to live with it. A few days ago I was rereading Linux Server Hacks and I got to the tip about using hdparm. Now I had set this up a long time ago but it suddenly occurred to me that maybe it wasn't working, and this was why things were so slow!

I went to my computer and did the timing tests with hdparm -tT /dev/hdc. The "Timing buffered disk reads" came back with 1.67 MB/sec, which even my years-old book says was laughably low. Encouraging! So I tried turning on lots of stuff with hdparm -d1 -u1 -X66 -c3 -m16 /dev/hdc. Unfortunately, it said that turning on DMA was "not supported", but everything else was turned on, and that got the speed up to around 3 MB/sec. (it turns out the old hdparm settings weren't working because my hard drive had changed from /dev/hda to /dev/hdc)

Not bad! But I wondered why I couldn't turn DMA on, as that would in general help the most. So after doing a little research I discovered the problem was that support for the IDE controller wasn't built in to the kernel. I decided to go ahead and download a new kernel anyway and (after eventually finding the right option) turned on the IDE controller supported. After installing it, I was indeed able to turn DMA on, and now the speed is anywhere between 30 to 60 MB/sec! I had to recompile a couple of times to get my sound and iptables filtering working again (I think the options changed between kernels), but I finally got it all up last night. My system is noticeably more responsive, and loading WoW screams (at least comparatively).

This makes me a happy panda!

So as djedi and I were pulling up to our complex yesterday and all of a sudden my Prius freaks out a little and puts up a warning light. No smoke pouring out of the engine, but I pull in to a parking space and djedi checks the manual. Some sort of brake problem, but it's not so serious that the car can't be driven. But it does say to take it in to get checked ASAP. "Crap" is the general thought, since we only have one car right now, so it being out of commission means no easy way to get to work. (and we're not sure what the hard way would be)

We get in and I call the nearest Toyota dealer, who says that they can maybe fit me in on Saturday, but Jeannie isn't in and this guy doesn't want to mess with her appointment book or something. Ooohkay. He tells me to call when they open tomorrow (8 AM).

Ugh...was looking forward to sleeping in, but we need a car! So I get up and call them. Nope, no way they can see it today. Great. So I go down the list of dealerships close to us. Get all kinds of "no"s and the occasional "we can't promise we can see it today but you can leave it here", which is just as bad for our purposes. I'm starting to get annoyed and a bit concerned when I make it down to the tenth one on the list (which by now is really not that close, but I figure it's OK to drive...). The guy is friendly and says I can bring it in, and to hurry. So I throw on some clothes, get directions and head out there.

40 minutes or so later I find the place, and again they're friendly and the guy at the desk says they'll diagnose it within an hour(!). I sit down to read (having planned to be there most of the day in the worst case) and start the David Sedaris book Dress Your Family in Corduroy and Denim, which is absolutely brilliant. Slightly more than an hour later I hear my name being called, and I rush out to see what the verdict is. Turned out they didn't find anything wrong: brake pads were fine, brake fluid was sufficiently present, and the code that set off the master alarm (that sounds like Apollo 13!) was nothing in particular, or something. The best part is that they didn't charge me anything!

So if you're in Maryland and need a Toyota dealer, I recommend Fitzgerald Lakeforest.

Some sort of crab-related product for dinner and then I'm going to another game nightish thing, all in the vain hopes of replacing the one we had in Austin!

Also, I have the theme song (track 3) to House irrevocably stuck in my head. I should buy that.
