I think this isn't your paper! (though it's easy enough to see in the picture)

If one is mainly interested in gender proportions, wouldn't it be better to just do one with 0 to 1 on the y axis? Presented this way it's not super clear to me what's happening with the proportions

Thought I proved something last week. Got shown a fatal flaw by my collaborator on Monday, got very disappointed and came up with another proof on Tuesday and sent it off to just to realise myself it was also wrong. Now I think I have a legit proof but what a rollercoaster it's been πŸ˜… (and no sleep)

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

A question: In your recent posts, you showed that there is (good ?) progress in rep code. Why is rep code a good metric for progress? It can't protect against phase-flip errors, right? Wouldn't it make sense to track codes that can protect against arbitrary noise. Is it just that there's no data?

Apart from transitions from/to a Gaussian fixed point, are there any other examples where field theory is actually useful?

Is there an existing *random* construction of 'good' quantum LDPC codes similar to the classical case? The only ones I've seen around are highly structured i.e Cayley graphs

It's always a sigmoid

Surprisingly LLMs have only recently surpassed the usefulness threshold for me: Generating an iCal file from a pdf or a website. Few months ago they would fail miserably, but now they can do it, with some back and forth. Now I'm fully convinced that they're going to enslave us all

Is there an example where generating randomness is the bottleneck?
