This is exactly how I feel about the recent ChatGPT models. It feels like I'm working with an incredibly enthusiastic junior student who listens to everything I say, checks it against my entire codebase, and thinks through all of the p

This is a very rough approximation of what the strong bots on chess.com do.

Yep. In accessibility research, they call these "situational disabilities". When you need to open a door with your arms full of groceries, you aren't so different from someone who is never able to open a door. Accommodations

Same here in Canada. The solution is that the machines accept a Canadian quarter to run the press, but an American penny to be pressed. No Canadian currency is harmed!

Yep, this is exactly what I thought of too... If you believe negative lines of code is the goal, then they've gotten 8x _worse_!

Sub 3 is incredible, congrats!

I suspect that they might have switched away from the booster separation on purpose. That's probably a risky moment of the launch, and they may have wanted to avoid televising a disaster like in the Challenger launch. Aside from that,

The conference organizers are very much aware of this possibility. Prompt injection for the sake of getting a positive review is explicitly banned.

Same here. If you shouldn't design for the average dimensions, what _should_ you design for?

Oof. I had a great time cracking the top 100 of Advent of Code back in 2020. Bittersweet to know that I got in while it was still a fun challenge for humans.

This is all right, but it just kicks the intuition into the assumption that the function is convex. As far as I can tell from the paper, this turns out to be exactly the argument they use to prove that (1/2, 1/2) is the optimal gu

Sure, I think it makes intuitive sense to me that you should play riskier when you're behind. The surprising part to me is that when you're ahead, even if you know that your opponent will play "sub-optimally", that doesn

I know that it minimizes the expected number of moves. But, the goal is to maximize the probability that you win in fewer moves than your opponent, not minimize the expected number of moves. Given that your opponent is playing some riskier

I find it somewhat surprising that the optimal play when you're ahead is still just binary search. Is there an intuitive reason why it's not productive to make riskier guesses? Why not use my lead to have some chance of sealing my

Wow. You reminded me of a computer engineering class years ago where we wrote assemblers and emulators for a simple architecture. I tested mine by writing a solution for one of the first Project Euler questions!

I wonder if it would show up on the heart rate (or heart rate variability) tracking from an Apple Watch or similar. My Garmin picks up stressful events all the time.

Incredible work! I recently gave a talk about TASing to an audience of CS grad students, and of course I had to mention your SMB3 runs. Your videos are phenomenal at making this stuff accessible outside of hardcore gaming circles.

The entire TAS file takes about 16 MB, far more than the 4 KB of RAM on the NES. During the audio + video playback, the TAS is streaming via the controller by making inputs roughly 500 times per frame (15 kHz).

I'm not sure about Gurobi or how the author used it in this case. But in general, yes: these combinatorial solvers construct proof trees showing that, no matter how you assign the variables, you can't find a better solution. In si

Wow, incredibly interesting to see what one of these manuals looks like! Thanks for sharing.

Yes: the reason why some data can be compressed is because many of its bits are predictable, meaning that it has low entropy per bit.

I think it is. Latency was just one of the problems he described. A physical controller sometimes adds "phantom inputs" as the joystick transitions between two inputs. Physical actuators also slow down with wear. A physical Atari-

I watched the talk live. I felt that his main argument was that Atari _looks_ solved, but there's still plenty of value that could be gained by revisiting these "solved" games. For one, learning how to play games through a ph
