    They don't count the additions or shifts because they're both linear time operations, and thus provably at least as fast as multiplication (both in an asymptotic and exact sense). …

    There could also be some degree of "(5) bandwagon effect" players, who pump money into an outcome specifically to get people talking about its possibility, thereby increasing its p…

    I feel like the section on primality testing with Fermat's test should at least make a shout out to Carmichael numbers and that for some inputs the probability you get a false posi…

    This is so tangentially related to the P vs NP problem that the title is basically pure clickbait. Remove every sentence relating to polynomial anything and the information content…

    What's a concrete threat model here? If you're sending data to an ssh server, you already need to trust that it's handling your input responsibly. What's the scenario where it's fi…

    Capping margins at a percentage also directly breeds inefficiencies. If you could spend $10M to fix a problem that costs you $4M/yr, you're effectively paying $10M now to lose $400…

    It depends on their test dataset. If the test set was written 80% by AI and 20% by humans, a tool that labels every essay as AI-written would have a reported accuracy of 80%. That'…

    TOTP inside a password manager doesn't make much sense to me. What's the point of two factor auth if both factors are stored together?

    Only finitely many values of BB can be mathematically determined. Once your Turing Machines become expressive enough to encode your (presumably consistent) proof system, they can b…

    I don't understand the point of this article, as it doesn't define an objective function. It just states a strategy that is only practically implementable for small board sizes (gi…

    Not specific to this article, but it's tragic that computer science curricula, and discussions of these algorithms, virtually never highlight the tight connection between binary se…

    I think the problem is in going for a Computer Science degree when you really meant to study Software Engineering.

    What counts as a standard formatter? Python one-liners are Turing complete even without semicolons, evals, execs, and with finite stack depth. E.g. some formatters keep this at one…

    This isn't an area I know much about, but wouldn't there be a security risk involved with storing the TOTP seeds alongside the passwords? Or is that not a real concern?
