@dang curious, is this post getting heavily downvoted or flagged?

I get that the geopolitical angle is sensitive, especially with the backdrop of today's big news - but I thought this was a really well-researched technical deep dive, right up HN's alley. (TIL: you could fingerprint gpu hardware just from an llm weights!)

I need to double check PyTorch code, I am not sure how robust this fingerprinting is without PyTorch "bug". Parallel philox based PRNG is a well-researched area and I am surprised (even if it is not secure-PRNG) it can fingerprinting like this. But obviously there are more people who are more knowledgeable on this can give their perspectives here.
