If anyone has any mathmo/statso friends that I don't know, can you pass them over?

In one place, we have Rabbi A, who rules "a", and Rabbi B, who rules "b". In another place, Rabbi A rules "b", and Rabbi B rules "a". We assume that Rabbi A cannot believe both "a" and "b" simultanously, which begs the question - which place reflects Rabbi A's position, and which one got itself confused? To resolve this, we bring an example from a third place, where Rabbi A rules "a" and Rabbi B rules "b," and take best-of-three. Assume that these three examples are the only ones available.

Now, my teacher says that best-of-three is an unreasonable approach. He uses an analogy of coins, saying "If you tossed three times and got two heads and a tail, it would be incorrect to assume that your next toss would be a head, therefore, if you have two sources showing that Rabbi A thinks "a" and one source showing that Rabbi A thinks "b," it is unreasonable to assume that Rabbi A probably holds "a.""

This just doesn't seem right. Basically because of the difference between a rabbi and a coin; a rabbi has memory, whereas a coin does not. We don't assume that a coin remembers previous heads and is therefore more likely to come down heads, but we do assume that Rabbi A remembers previous "a" judgements and tends to apply similar reasoning. So that is a question that relates to how many coin-tosses you need before you can reasonably conclude that a coin is biased. I only have vague memories of how you do this - but from the start it's a lot more reasonable to assume that Rabbi A is biased, than to assume that a coin is biased. But I can't formulate this sufficiently well to convince my teacher. If one had more samples of Rabbi A's thinking, it would presumably get better - how many more? I can't remember how you do this kind of test.

Paid computer boffin has installed a dinosaur in Pardes, and spotted W pulling the printer out of its back and plugging the printer into his laptop. He got very, very distressed, and solemnly informed W that doing that can result in irreparable damage to the computer, unless you shut down completely before removing the plug. Only if it was a USB printer, he said, would that be safe to do.

OK. I have never, ever, in fifteen sentient years of computer use, had a problem result from pulling out pin plugs while the computer was turned on (unless it was the power). Pulling out USB plugs, on the other hand, frequently causes an interesting range of problems, which often end up destabilising Windows to the point where it doesn't function at all.

Idiot.
