    I am not sure that "Dante is clearly writing in the expectation that his audience will know these references" as claimed in the article. He put a lot of learning into the work, and…

    A couple of issues that came up for me when porting from x86 to ARM recently: 1. The x86 architecture gives programmers a lot of memory ordering guarantees, so that communication o…

    This bit of speculation goes back at least to David Eugene Smith (1925), "History of Mathematics", volume II, page 59: "There is a possibility that the Romans avoided IV, the initi…

    A warning heuristic needs to have a low false positive rate; a low false negative rate is nice but is not necessary. The purpose of a warning is to detect some common errors withou…

    Here's the letter from Chris Boardman and the other commissioners, which doesn't seem to be linked from the Guardian story: https://www.greatermanchester-ca.gov.uk/media/2145/19-13…

    This seems like a good idea to me, since there's evidence that programmers are making this mistake, and the proposal is to add a warning only for the expressions that are most like…

    This is a well-known principle of urban transport. If driving is faster than the alternative transport mode (whether that's public transport, if any, or walking), then at the margi…

    The difficulty of Chaucer for modern English speakers is exaggerated because of the unfamiliar spelling. The reason that modern editions don't modernise the spelling is that if you…

    This one-line shell script is a bit simpler: base64 /dev/urandom | head -c 16 (Vary the number of characters according to the desired entropy: you get 6 bits of entropy for each ch…

    It's slightly more efficient to squeeze non-alphabetic characters first and then convert to lowercase, rather than vice versa, because in the former case most of the non-alphabetic…
