I did not. Post-conditioning by your comment and the other one,I can see some signs such attempting to be unusually comprehensive. The 'atoms in your liver' could be an awkward human trying to be poetic about scales.

I still don't see idiomatic markers of AI so that's scary if your claim is correct.

I can roughly guess the train of thought and I am a bit surprised that Claude is failing you.

That said, I am puzzled at the algorithms that Claude & GPT "get" and ones that they do not.

(former physicist here. would love to know the kind of things you're working on. email on my profile)

I wonder how many completely u related applications have that interval check logic coded up somewhere. I'm pretty sure I wrote one for my work codebase. Would I bet my life that the < and <=s are correct? Nope.

Yes that's a brilliant article. I do not think it is in the book yet?

I used a poor man's version to solve a puzzle where one arranges polymino pieces on a grid spelling out the date [1]. No pointers, just keeping track of deleted rows and columns in the recursion.

It is not at all obvious that all 366 days can be solved. To my dismay all of them can be solved in multiple ways - as a human I find some days quite tricky.

Hey I am trying to get back into German. What are some of the good channels that you've found? I remember Fokus Deutsch.

Spent 4 years in Germany but never took a course out of sheer laziness. I can read children's books but every native speaker sounds like they are zipping along at 2x speed.

Ah this is great.

I wrote my own solver in Python+Numba. You've probably seen Robot Reboot https://www.robotreboot.com/challenge. I had a parser that could take a screenshot of the daily puzzles and feed them into my engine. Your post might just give me the kick in the pants to put it up online.

Curious if think this made you better at RR. I started out absolutely terrible, and actually got to the point where I could occasionally match the best scores on Reboot (but not their times of course!).
