  • I spent an hour and a half arguing with my brother about probability, because he asked ChatGPT what the probability that he and his daughter were born on the same day.

    ChatGPT said 1/113465 which it claimed was 1/365^2 (this value is actually 1/133225) because there’s a 1/365 chance he was born on such and such day, and a 1/365 chance his daughter was too.

    But anyone with even a rudimentary understanding of probability would know that it’s just 1/365, because it doesn’t actually matter on which day they both happened to be born.

    He wanted to feel special, and ChatGPT confirmed his biases hard, and I got to be the dickhead and say it is special, but it’s 1/400 special not 1/100000. I don’t believe he’s completely forgiven me over disillusioning him.

    So yeah, I’ve had a minor family falling out over ChatGPT hallucinations.












  • Well, the problem is you don’t know what you don’t know. One of the first example tasks in the paper was regarding implementing a symmetric cipher. Using a weak cipher was recommended by AI tools sometimes, these developers didn’t know that some ciphers were weak. Additionally, even when the AI tool recommended a strong cipher, such as AES, it generated code that screwed up an implementation detail (failing to return the authentication tag), making the result insecure. And the user didn’t know it was wrong because they didn’t know it was incomplete.

    There’s no substitution for domain specific knowledge. Users who were forced to use traditional tools got the answer correct significantly more often because they had to read, process, and understand the documentation for the libraries, which meant they understood why the symmetric cipher was the way it is, and what additional information needed to be reported and why.






  • So please forgive me if this is a rather naive question. I haven’t seriously used Windows in nearly 15 years.

    I seem to recall runas being a lot like su, in that you enter the target user’s credentials, rather than your own as in sudo. This works because sudo is a setuid executable, and reads from configuration to find out what you’re allowed to do as the switched user.

    Is the behavior of windows sudo like unix su or unix sudo with regard to the credentials you enter? Can you limit the user to only certain commands?
