Followup: Athens bombing

As more details come out, it looks like I was spot-on last night in my analysis of the embassy bombing in Athens. Hot damn!

It turns out one of my coworkers used to work for Evolution Robotics, which made the ER1 I used in my robotics research a year and a half ago. It’s nice to know that he agrees with me that the ER1 could have been a great product except the basic software, power converter, and marketing department were crap (though apparently if we had sprung for the $1,000 software it would have worked better). Intriguingly, he also thinks that adding a laptop and camera to a Roomba is a good way to get a cheap robot, which is what Prof. Dodds is doing now (he was my robotics research prof). Nifty!

We Are The Champions, My Friends

As Ricco mentioned in a comment to my previous post, it turns out that we won the scavenger hunt with flying colors. We took first place in the scavenger hunt, and Sony gave us an Aibo for that (this was unexpected; we didn’t know that there were any prizes). We also got a Technical Merit award for “Overall Excellence in an Autonymous System,” which I’m really happy about – all robots at the conference were eligible for technical merits, so we apparently beat Sparticus to that one, (though it got awards for being awesome too). We’re dubbing our awards the “ghetto-badass” award and the “holy shit – it worked!” award, irrespectively. As Ricco also mentioned, our robotics lab now has 2 Aibos, and they need names (the one we currently have is called something like AIBO1 right now). At first, we were thinking of naming them Homebrew and Budget (or various spellings thereof), since that phrase has become a bit of an inside joke for the four of us (perhaps only the three of us, since Ben was out of town when we wrote the abstract). However, we might call one of them AMBR (Alan, Mac, Ben, Ricco) instead, since some people think it’s wrong to call a commercially-made robot Homebrew. Any feedback here would be appreciated.

Wednesday night, Dodds took us out to dinner to celebrate. It was hilariously like he was back in high school – since he’s spending a year on sabbatical at CMU, he has moved to Pittsburgh and is living with his mother in a 3-story penthouse above an office building. To pick us up, he borrowed his mother’s car. We went to the City Grill, which was great, and we then rode an incline, to get an historical perspective of Pittsburgh (inclines are like trolleys that go up the sides of mountains). While trying to find a parking spot, Dodds drove for a bit half on the sidewalk and half on a gravel parking lot, and since the Prius sits so low, we scraped the bottom against the corner of the sidewalk, eliciting “OOH”s from the dozen or so people walking by. When we finally got to the incline, Dodds didn’t have enough money to pay the fare for the 5 of us, so he borrowed money from both Mac and Ben. We then took the robot to Dodds’ mom’s house, where he will keep it until school starts up again. However, the building was locked and Dodds had forgotten his keys. He borrowed Mac’s cell phone to call up and see if someone could let us in, but there was no answer. So what does he do? He scales the fire escape! He also claimed to have done this several times before. It was hilarious – he was wearing suit pants and a nice, collared shirt. Our estimed professor – climbing the fire escape as though he were sneaking back home after curfew. Mac had the foresight to recommend that we get pictures of this, which we took profusely. He finally gets up there and gets his mom to come let us in. Then, to pay back Mac and Ben, he borrows money from his mom! It was just like we imagined he would have acted in high school.

On the whole, this has been the best week of the year, and I hope to go to AAAI again next year. If you’re interested in anything remotely related to AI, I strongly suggest you look into going, too.

Also, we were apparently mentioned in Wednesday’s edition of the Pittsburgh Tribune (the 2nd page of the local section, I think). Unfortunately, we don’t have any copies of this paper. If anyone can find one, we’d like it, or a scanned copy of it, or something. On a related note, we forgot to videotape the robot scavenging for the judges. If anyone happened to have been at AAAI and taped it, we’d like a copy of that too.

Back in the midwest

Well, I’m now home in Minnesota. Research went OK. The last day was a lot of work though – Friday morning, we had a meeting to make sure that everything was ready and done. Then, Prof. Raugh decided to tell me that he had looked through my part of the report and had some changes for me to make. I spent all afternoon making changes, and getting the final copy ready. I put the entire thing in a .zip file (just over 3MB zipped – quite a large piece of work!), and I was about to mail it off! I decided to check my email just in case anything unusual had happened at the last minute, but forgot how to do that from the terminal room. So I skateboarded back to my room, and check my mail. Lo and behold, Sarah has also made some major changes to her part of the report, and could I add them to the final copy? Mind you, this was at 6:00. I was about to be done. So I save her changes and go back to the terminal room and put them in the final report, rezip the whole thing, and send it out. I also put a copy in the directory Claire made for this project so that we can all access it on the math computers. It’s now about 3.1 megs (we had a lot of changes, apparently!). I finish work up at 6:30. :-P But it’s now done.

It’s a little weird being back in Minnesota. Marc can now drive, and has a job lifeguarding. So he’s going to be taking the car a lot, I fear. He has also decided to put bumper stickers on the back. He got one of those stickers from WootWear, and one from the USA Fencing Organization. I don’t want my car covered in bumper stickers! Get those off there! Luckily, he hasn’t put the fencing one on there yet, and I’m hoping I can persuade him not to. hm…

Though my computer is at school, it is turned on and the SSH port is open, so I can continue to install programs on it while I’m here. This evening, I started building OpenOffice. We’ll see how that turns out. I also have a copy of Knoppix with me, and have been impressing my dad and brother with its little features (everyone is impressed with the “fuzzy” clock, and Marc really likes the ASCII movie player). Since I have X-forewarding turned on on my machine at school, I can also check my email from there. This is really nice, because I can continue to train the Bayesian spam filter, and keep all of my email in one place. Whee! :-D

In world news, the Darfur Conflict is finally getting some well-deserved attention. The New York Times (free registration required, or go to BugMeNot) has stuff on it here. It even made the local paper here (the Star Tribune), which barely has any news of import. I for one am glad that Darfur is finally getting some attention. I’ve been following the conflict for several weeks, and at first I was quite dismayed that the rest of the world didn’t seem to notice (though perhaps it merely appeared that way because I was living in the college bubble). Well, I just thought I’d try to increase awareness of the issue.

It’s late, so I’m now going to bed. Goodnight!

Well, the 2nd graphics card I got for the new monitor isn’t as great as I had hoped. I can see why the CS department was throwing it out. So this evening, I bought a new one, that should suit my purposes quite well. It’s a GeForce 2, so it’s by no means a bad card, though it’s far from good. But I’m not a high-end gamer, so I’m happy with it. It should arrive Monday-ish, and then I’ll finally have both monitors running at good resolution.

The 4th of July passed fairly uneventfully this year – there were fireworks in the evening, and that was fun, but not much else happened. I’m still slowly moving into the double. about half of the posters/other art is up, and almost all the big things are moved in. It’s really nice that I don’t have to move it all over 1 day, and that I can spread it out over a month. It’ll get done eventually.

Work has turned frustrating once again. I need to write 4 more FORTRAN subroutines, but these aren’t documented in the user manual (they’re mentioned in passing in a table). I have a sample file of what they might look like, but the comments are written in German. BabelFish has helped a bit, but not much, as it doesn’t do technical mathy words. And Prof. DePillis was out of the office, so I couldn’t ask her for help. Hopefully tomorrow. *sigh*…

Bridge Sectionals

On Tuesday, Andrew and I went to the ACBL sectionals tournament. We were in the stratified pairs competition, so we were only competing against other players with less than 20 masterpoints (I have 0 and Andrew has 5). We did pretty well – we took 5th place out of 7 partnerships overall, and took 2nd out of 3 in our stratification. I’d like to go back soon. We’ll see.

Mac bought the car he’s been looking at for a bit – it’s an offwhite Toyota pickup that seats 2 and a half. 4 cylinder engine with a lot of pick-up. I got to ride in it a bit because we did errands and bought stuff tonight. Food, power strips, and some mesh to make screens for the windows. It’s summer, so the bugs are out in force. Being a college student, I’m up late and keep my lights on after dark. Let me tell you, when the windows are open, the bugs come in droves! I figure that with mesh, velcro, and a liberal application of duct tape, I should be able to make screens for the windows and keep the place mostly bug-free. Robert is coming on Friday for Rachel’s birthday, so I hope I can do this by then. I doubt it, but it’s nice to have goals. As Douglas Adams once said, “I love deadlines. I especially like the whooshing sound they make as they go flying by.”

Oh! I now have 2 monitors hooked up to my computer! I got the 2nd monitor from Travis at the start of summer, and had been looking into getting a graphics card. Then, yesterday, Mac mentioned that the CS Staff had been cleaning out the machine room, and were going to throw out a bunch of 2nd-rate graphics cards, and I should go get one first. I only wanted a crappy one anyway, so I got it. The one I picked out happened to not work, but a second card did, and life is good. At 1024×768 it can only support 16bit color, but I don’t really care; I’m not using the 2nd monitor for raytracing or games.

On the academic side of things, Clair finally got DIRCOL up and working yesterday, so I can start building a model in that. Now I just need to talk to Prof. DePillis a little about the finer points of the system. Raugh thinks I will have a paper to publish by the end of the summer, but I’m not so sure. Time will tell. and it would be pretty neat. Tomorrow’s a Stouffer talk, so I won’t get too much done in the morning. Still, I’ll be getting paid to eat food and listen to a prof talk about what they’re doing this summer, which is always interesting.

So… yeah. All in all, life is pretty nice right now. Having said that, I’m going to sleep.
