Stateless Actors

Recently, I was asked an interesting question. If the purpose of an actor is to protect mutable state, is a stateless actor pointless? At first, I thought it was an easy answer. Actors exist to define a little, protective bubble around state. They "isolate" data away from any unsafe accesses. An actor that has nothing to isolate seems like a strange thing. A thing I run into from time ...

A Probabilistic Algorithm for Repairing All Roads in Lebanon via Papal Visits

The viva voce defense is a protocol meant to certify a candidate's independent research capability, but it becomes less sound when the prover has access to a large language model oracle. The protocol's soundness is controlled by transcript distinguishability, and increasing it requires fairness and cost consequences, leading to a soundness-fairness-cost tri-lemma.
