  • Their problem:

    So apparently NetHack has a mechanic that slightly changes how the game plays every time it’s full moon according to your system clock

    The model wasn’t trained on a full moon. They had a system to set up the environment for replicable results but it didn’t include modifying the system time.

    It reminds me of another bug with the system time, which a friend of mine encountered. He was working on hardware and he was getting a lot of units that worked fine at the factory, immediately failed at the client’s location, and then worked again when they were returned to the factory. It turned out that when these machines were turned on, their embedded OS automatically queried some server to update the current time. The client’s internet connection had such high latency that the server’s response only came back after the machine was already in use. This generated a huge delta-t value that triggered the sanity checks and shut the machine down. The factory had a much lower-latency connection and so the race condition could never be replicated there.

    As for the weirdest bug I ever encountered myself: a compiler generating bad machine code. I have often said that the worst part of programming is that the computer always does exactly what you tell it to, but that was the one and only time in twenty years that the computer actually didn’t.






  • If you present me with a trolley problem in which the only way to destroy Hamas also kills a million children, I won’t know what the right answer is. I suppose it would depend on what would happen to Israel if Hamas wasn’t destroyed.

    However, the moral calculus for nations is not the same as it is for individuals. The standard established the last time the Western world fought a war it took seriously does seem to be “as many as it takes” and I suspect that this would still be the standard if such a war happened again. (All those nuclear missiles we have ready aren’t precise weapons…) In that context, demanding that Israel should show restraint that other countries haven’t and wouldn’t seems like hypocrisy.



  • If you trust the casualty numbers that the UN Is using, then they imply approximately 3.7 civilians killed for every combatant (with the assumptions that children make up half the population and that children are never combatants). I don’t trust those numbers but I admit that if I did, I would think they didn’t look good for Israel. I suppose we’ll have a better idea of what the truth is years from now when historians reach a consensus, but until then I’m going to reluctantly trust Biden’s judgement because the US government probably has secret information unavailable to the public. (Biden is biased by his need to be re-elected, but I don’t get reports from the CIA so that’s the best I can do.)

    As for justification: Israel should make reasonable efforts to minimize civilian casualties while accomplishing its legitimate military objectives, but Israel should not sacrifice its ability to accomplish those objectives in order to protect civilians. In other words, Hamas doesn’t get to hold Palestinian civilians as hostages against Israel. If they try, then they are to blame for the resulting civilian casualties. The alternative is simply unworkable in practice, because the ability of Hamas to put Palestinian civilians at risk is almost total.


  • over 2/3 being civilians by their own count

    People often bring this up without noting that such a ratio would not be unusual in urban warfare against a well-prepared enemy even when the attacking army is doing what it reasonably can to reduce civilian casualties. Compare it to Mariupol, an example of what happens of the attacking army is unconcerned about civilian casualties: 25/26 of Ukrainians killed were civilians according to Ukrainian estimates. (8/9 were civilians if we use the Ukrainian numbers for how many of their soldiers were killed but the more conservative Human Rights Watch numbers for civilian deaths.)
