the GRE

I doubt anyone will care, but I just wanted to get this out there:

The GRE book I had (and probably most other ones) will tell you that you can’t copy in the essay editor, only cut and paste, and that you have to click some buttons to do those things. This is false: I noticed that Shift+Ins and Ctrl+Ins perform copy and paste as usual. I suspect that Shift+Del will cut, but I couldn’t remember that one to try it during the test.

This has been your DZHU™ PSA for the day. Thank you.

Games

So today I went to the Google Games, an event at the Google Cambridge office involving a bunch of geeky competitive events.

Highlights:

• There was a music-identification round (part of a larger trivia round), during which they rickrolled us and played awesome music like the Firefly theme, Korobeiniki, Do You Wanna Date My Avatar, and Dragostea Din Tei. Unfortunately, I was unable to correctly name Korobeiniki, as I have long held the misconception that it is called Kalinka. (I’ve been disabused of the notion before, but still couldn’t remember the right name.)
• There was a puzzle round; I spent the last half hour or so working through about 70 cases of one puzzle, looking for the one that satisfied certain conditions. At the one-minute-remaining mark, I had three cases left. I managed to eliminate one more of them, and then sent in the other two as answers, feeling sure that I had missed the answer. Instead, one of them was correct! I was both happy and sad.
• I was really excited to play Wii Sports Resort (there were supposed to be rounds in rowing, basketball, skydiving, and swordplay), and I was the only one on the team who’d played before, so we kind of figured I’d do them all. Then they said each person should only do one event, so we decided to be good competitors (they almost definitely wouldn’t've noticed had I done them all), and two other people did the first two events (I wanted to do swordplay). Then time ran short and the last two rounds were canceled. I was and remain severely disappointed.
• We were the highest-ranking Harvard team (the first five spots went to MIT). Success!
• Foosball. Playing with new people was fun. There was a left-handed table there (you shoot left instead of right); interesting, but it was also a really bad table.

interview

I had a phone interview with D.E. Shaw today (I’m applying for a summer internship there). I was kind of afraid I’d get asked about what I wanted to get out of it and where I wanted to be in ten years, which I would’ve had an awkward time answering (that is, arguably, a bad thing in its own right, but never mind). It turned out to be basically fact-based, so that was okay. I talked about the work I did with an astronomy professor last term; the interviewer had me talk about how we processed the data, then asked me some questions about the statistics of it. I remembered the process pretty well, though I guess I wasn’t very clear and had to retry some of it. I remembered the Poisson distribution, but he asked about the conditions for one to be approximated by a normal distribution, which I didn’t really remember. I said it’s acceptable when the expected number of events is at least 20, which turns out to be about right.

After that he asked how to do quickselect, which I answered fairly well, and how to partition an array in place, which was okay, though I didn’t say it very smoothly. Then he asked a pretty simple probability question, which I sort of figured out how to do pretty quickly in kind of a neat way, but it was different from what he was expecting and I didn’t explain it very well, so that kind of fell down. I got the expected method with some prompting, but I really should’ve made it more clear that I actually knew what I was doing. I think he did somewhat recognize what I was saying, at least. Still, I think that was quite a trip-up.

A silly post. Happy ‘teens, Blandfill!

I’m making a silly post! This is so I can make a more thoughtful post later without having any backlogged sillyness to interfere.

I’ve been playing Diablo 2! I finally beat Duriel. I’m a necromancer and I summon skeletons. That game is hard and sometimes repetitive so I’m gonna lay off for a while.

There was a robotics kickoff! I didn’t sleep last night! Instead I played Diablo 2 with Nico. Nico has returned to school, to the best of my knowledge. So, today I am pulling an all-day-er. I made up this term; it describes when you have been up all night for some reason and, if you were a rational person, you’d go to sleep as soon as you were done with whatever was keeping you up all night. But I decided I want to stay up so that my sleep clock (totes not a biology person, someone explain why it exists) isn’t all screwed up, and I’m trying to make it all the way to normal-people’s-bedtime so I can be set all right and stuff. It’s about 9:20 PM as I’m writing this sentence so I think I’ve been mostly successful! Also hugely sleep deprived, which is why this post is a collection of words that lack logic or intelligence behind them.

Here’s a silly video to break up the pace:

I have been playing the xkcd game for like two whole hours without ending. (The xkcd game is something we made up, I think, where you click “random” until you get a repeated comic.) Usually it doesn’t take more than 20 minutes, but I’ve been going really slow and leisurely, analyzing the details of each drawing, trying to make sure I don’t miss any of the jokes. (Like backslash escape sequences, for example — something I wouldn’t catch in a handcuffs reference even if I was vaguely familiar with the idea when comic 234 came out). I think my patience to do it so slowly is very related to my sleep-dep-ness; reading xkcd endlessly is trance-like.

I am reasonably sure that I haven’t been just forgetting which ones I’ve seen since I began playing, since my browser cache would load previously seen images instantly but all the comics I come across load noticeably slower than instantly.

I imagine this blog post is pretty boring. I’m streaming all over my consciousness right now.

This comic is funny.

To come, two posts (which I might combine into one) on less playful topics: A) New year’s resolution (1240×1480? ^_^), B) What happens to me when I am at home.
