Bloom and cuckoo filters provide fast approximate set membership while using little memory. Engineers use them to avoid expensive disk and network accesses. The recently introduced xor filters can...

The tech giant said providing encryption keys was a standard response to a court order. But companies like Apple and Meta set up their systems so such a privacy violation isn’t possible.

what if the new meta is decentralized storage with fhe (already allows working at acceptable speeds in stream)?​​​​​​​​​​​​​​​​

let’s revisit this topic in a couple of months

For quality of life, it is better to err on the side of being an optimist and wrong, rather than a pessimist and right

Quantum computing and blockchains: Matching urgency to actual threats

we added one of the final tests to ensure that the signal and noise are structurally indistinguishable:

easy to run test: "make test-struct-v2"

this paper demonstrates practical lpn attacks up to n approx. 200 (solved in 290 mins), hfhe uses n = 4096 (which puts us well beyond the practical attack boundary with complexity exceeding 2^200)

“prompt engineers” can't even solve a system of equations…
