memnus: Dave Davenport and Lovelace with quotes from Alice In Wonderland (We're All Mad Here (Narbonic))
There's something about the sky after an evening snowstorm. The clouds linger low, lit from below by city lights and above by a full moon, and somehow it's nothing like the nights I got so used to in Claremont. Maybe it's the cleanness of the air and ground, before the snow has had a chance to get dirty and everything is still white. Maybe it's the mountains so close, rising up against the clouds. Maybe I just feel different this year. Whatever it is, it's about damn time we got some snow.

In honor of my perpetual boredom and neglect of aerobic exercise, I walked down to GameStop to look for a dance pad. Computer gamers take note: a "universal" connector includes Playstation, X-Box, and Wii. Note a distinct lack of USB qua USB - although an X-Box plug is the same pins in different plastic, and Nintendo may well be, no appropriate converter is included in GameStop's store brand pad. Even worse, the store in question doesn't carry anything from Ignition.

They did, however, have Wiis in stock.

No, I didn't get one. I was prepared to spend a certain amount for the reasons listed, but not six times that much. If I get a job next semester, I'll revisit that decision. There's a couple possibilities on the table, two jobs that have about as little to do with each other as penguins and pandas. Disappointingly, they're utterly incompatible.

I'm going to be off the grid for a while.

My family on my mom's side has their giant reunion at Thanksgiving every year, in Virginia Beach. I'm still making up for missing for of those in a row - not to mention forming impressions of the gathering as more of a grownup than a teenager - so that's where I'll be Thursday.

But! I am also maintaining a long-distance relationship with a lover in southern California, and any long weekend is an excuse to snag some Frances time. So I will head there as well!

The end result, five flights in five days (SLC-ATL, ATL-ORF, ORF-CVG, CVG-LAX, LAX-SLC). It'll be exciting, and give me plenty of time to grade midterms. Will it be worth it?

Hell yeah.

There should be more afternoons like this.

Chipotle opened its third Utah location today - this one under a mile from my house. Addict that I am, I headed down into the lunchtime crowds (and quite a crowd it was); by signing up for some spam I seem to have won myself a coupon for a free burrito. Taking my loot to go, I headed a few doors down to the new Sugarhouse Coffee location, settling in with a large hot chocolate, the latest Poly Weekly episode, and a geometry textbook, thoroughly relishing all but one of the above. That, and I may have some progress on the latest assignment (out yesterday, due tuesday, dammit). From there I headed down to the range and got nearly two hundred shots in. From here I think I'm off to bike around the park a while.

Did I mention it's warm and sunny? I can't imagine that it'll last.

ahh.

Is anyone else having issues with AIM this week? I'm using Pidgin 2.2.2, and keep getting "socker error #10060" (connection timeout) on AIM and ICQ. GTalk, LJTalk, and everything else are working fine, so it's not a firewall issue; older Gaim on my laptop is having a similar problem.

Man convicted for sex with bicycle (BBC News)

The headline would grab anyone's attention. The charge, "sexually aggravated breach of the peace by conducting himself in a disorderly manner and simulating sex," makes it sound like he was in the middle of the street at the time, which would be a different matter entirely. This turns out to be far from the case.

The act itself doesn't faze me. I've learned well that people do some bizarre stuff with their genitals. No, what weirds me out and makes this entirely fucked up is that this "breach of the peace" was performed in the man's own bedroom, behind a locked door. And for it, this gentleman has been placed on a sex offenders registry for three years.

Three years. For fucking his own bicycle, in his own locked bedroom. The hell???

(In the interest of fairness, this was a bedroom at a hostel. There may be rules in place at hostels regarding what is and isn't private space, but somehow I suspect that if the cleaners had walked in on him with another consenting adult, there would have been nothing more than a few blushes and a quickly closed door. Feel free to correct my assumptions here.)

Sex offenders registries help no one, when the innocent bicycle fetishist and the high school senior that happened to turn 18 before his high-school-senior girlfriend are lumped in with the serial stalkers and baby-rapists. That's a big gap, here, but two years from now nobody's going to look at this guy and see a guy caught in an embarrassing, but harmless situation. No, they'll see a sex offender, and treat him accordingly.

Sense of perspective, anyone?

I officially work in retail now! Well, at the archery range anyway. I'm the one holding down the register 12-6 on Sundays. All you local folks should come rent bows and stuff from me. :-) (And no, I don't work on commission. Sundays are apparently really slow days all the time. Yesterday there were all of ten people between noon and four, then no one for an hour. Just as we finished closing up the cash register, a crowd of eight piled down the stairs, with half an hour until closing. Never mind that Larry has a bus to catch...

I dropped my bus pass somewhere as I was running around today. Since I checked the lab spaces where I was sitting, that means it either fell out on the bus itself, or as I was walking across campus ... neither of which bodes well for getting the damn thing back. I got it replaced, and if it does turn up after all I can get a refund, but arg. Not making me happy, that. That and trying to build a UI in Matlab (that's right) have made for a tear-your-hair-out day, even though I spent the whole time convinced it was Tuesday. No such luck, apparently.

We're down to four weeks of classes. I have the Matlab UI and related stuff (though the group has left the coding to me), the Fleck model (for which I finally have a face template), and in theory some geometry homework (which will be scheduled exctly backward - written work this weekend, programming over Thanksgiving). No finals, and three assignments and a midterm to grade. That doesn't seem like much, at all.

So for my Human-Computer Interaction class, I'm working on a project related to color-blindness. I'd like a few volunteers that I can show some pictures to, and ask for opinions - either whether two things look the same, or if a modified image looks hideously ugly even though the colors have better contrast. Also, if you have any examples of websites with poor color choices, links would be awesome.

First set of images )

Frances was here and gone. Rocky's half done. I have a week left in this house until I have to move, and simply have not started packing (though the aforementioned Frances took away some kitchen stuff I won't need). This would be the perfect time for a power cycle and reset ... would that I could do that on command.

I'd like to take a moment to be grateful for my instinctive sense of balance, that stays with me even when drunk. As I was jumping around on stage last night, the (five-inch) heel on my left boot broke, hanging on by just a flap of pleather. I managed to hang on through the scene and the credits, but now it's got superglue splashed into it and I don't know if I can trust it.

I vaguely want something mindless to do. NWN2 would take too much thought, I'd rather not play DMC3 on the keyboard again, and I beat Half-Life. Currently working on downloading Half-Life 2, but it's huge. I do want to see what Skylark can do with it, though.

Monte Carlo estimator says:

- Numbers in D are skewed toward smaller values.
- Approximate size of D is 1.7n.

And I had my characterization of the problem slightly wrong, which caused some confusion: the terminating condition should have been "when you cannot choose any more numbers" as [livejournal.com profile] zane314 guessed.

I'd like your thoughts on a problem. (Here, all "randomly chosen" numbers are taken from the same continuous real distribution.) Suppose you have a set S of n randomly-chosen numbers, and a set D, initially empty. Begin by removing the largest number from S and placing it in D, and adding another random number to S. Now take the largest number from S that is smaller than the last number you chose, place it in D, and replace it with a random number. Repeat until you've taken the smallest number from S.

- What is the distribution of numbers in D?
- What is the expected value for the size of D?
- Bonus question (I know the answer to this one!): Why is Brian thinking about this problem?

I'm about to start in on a Monte Carlo estimator of the problem, but I'd like some theoretical input.

Tournament report: Desert Open 2007
Single FITA

There's a strange impression that I'm starting to get about archery people, at least the Powers That Be: they seem to fetishize The Rules, even moreso than most of the fetishists I know. As such, the USC star that put on a surprisingly good show at the olympic trials last week was not considered a college division archer.

He was a hundred points ahead of me, while I was another hundred points ahead of the official second-place finisher.

Despite the silly little belt buckle I now have (belt buckle? the hell?), I don't want to consider this a competive victory. Rather, I hit some important personal milestones, and hardly noticed them until they'd passed. I opened up scoring with an X at 90 meters, anchoring a 51, and followed that up with a 48. Things were downhill from there, but the resulting 250 will be my new standard for that distance. 70 started off iffy, but I pulled it together at the end. The next day I set my goals high and nearly had them: only one point from my personal best prat 50, and five at thirty. Grand total came to 1148, only twelve points below the personal best that felt so astounding at the time and that I'd previously not come close to matching. If that doesn't even feel like a spectacular day anymore, I must be getting better without really noticing. From here it's a matter of:
  • Equipment upgrades. I need a new cushion tip on my plunger at the very least, and probably a new v-bar block. New strings would be nice; I've also been offered a new riser, which would be the ultimate big change.
  • Wind practice. This is awkward, because it's going on winter season, and starting to snow in Utah.
  • Fine-tuning my grip. Since I stopped shooting with a glove, there's been a spot on my handle that can press into my palm painfully. I either need to file that off, or just get that new riser.
  • Poundage increase. This will also help with wind.
  • More tournaments. The next one in SoCal is November 10th, in Van Nuys, which is not particularly accessible from anywhere I've previously stayed. From there it's solidly into indoor season, with the Utah Open in December.
I'm now in San Diego for the week, but with homework and without a car, so not looking too hard for anything to do.

It's the last week of school before fall break. Somehow, I don't have any major homework - just a meeting after HCI today to hammer through the latest assignment in that class - but I feel antsy to Do Something. I want to go climbing, I think. Or I want to throw some rope, tie something up. Or I want to take down the new riser I've had my eyes on and start setting it up (nothing like being told a week before a tournament that your hardware needs replacing). Something, anything but sitting around school all day.

Office hours are going to be crazy busy today. Not only do people have their first threads assignment (with STL thrown in for the hell of it) due tomorrow, but they also have a midterm on Thursday to add to the panic! I might also have a midterm of my own coming up; I honestly don't know. Would be good to be warned about it.

I'll be in the LA area next weekend. Anyone going to be bored?
