It's a math paper written for mathematicians.

It's not possible for someone who's not a specialist in the field to understand it (unless there are more elementary proofs, of which likely none exist).

They almost certainly pay for tokens, which is absurdly expensive

The pendulum synchronization effect is the opposite of your claim. It has a physical causal reason for why pendulums become synchronized. Your claim is that it was random and independent.

From my rough understanding, tokens are about five to ten times more expensive than the prepaid plans

I interviewed for an internship in 2006 and didn't get any brainteasers, but I got some pretty interesting questions that were somewhat computer science-related:

1. Suppose you have a binary tree (NOT a binary search tree) where each node with pointers to its parent and children. Given pointers to two arbitrary nodes in the tree, find their lowest common ancestor.

2. My favorite: given a uniform random number generator mod 5, create a uniform random number generator mod 7

3. Forgot the exact question, but something along the lines of: suppose you want to keep track of function arguments as you call them. How do you do that?

I got (1) and (2) and utterly failed (3). (3) is entirely trivial and basically a stated fact if you know how anything about how operating systems work, but I was a freshman in college and didn't know that function arguments got pushed on a stack in memory, so I was totally lost.

I think all of Luna's are bad. The only decent one is sol @ xhigh. Even sol @ max is weird. Sol @ high and @ medium are ok, and every other single one across every model is bad.

I'm open to hearing, please elaborate

Do you disagree with any of the data or conclusions?

From this reply, it seems that it has nothing to do with `/effort`: https://github.com/anthropics/claude-code/issues/42796#issue...

I hope you take this seriously. I'm considering moving my company off of Claude Code immediately.

Closing the GH issue without first engaging with the OP is just a slap in the face, especially given how much hard work they've done on your behalf.

I assume they meant that "Claude Code is so good..." and that they cancelled Currsor and just use CC + VSCode.

That's all factually incorrect. The reason that HFT is valuable to society is exactly because it trades at the microsecond scale. That's how it provides the most liquidity.

Flash crash was transient and had no impact long term value. Neither does volatility.

HFT doesn't inflate or deflate any valuations. They operate at the market microstructure level and provide liquidity. HFT firms have no impact on the long-term value of assets.

Thanks for the AMA Peter!

What impacts are you seeing as a result of the $100K H-1B fee which took effect on 9/21/25?

This is different. AI is an existential threat to Google. I've almost stopped using Google entirely since ChatGPT came out. Why search for a list of webpages which might have the answer to your question and then manually read them one at a time when I can instead just ask an AI to tell me the answer?

If Google doesn't adapt, they could easily be dead in a decade.
