      Yes, this is probably misleading and imprecise! But we don’t have a coherent account of what’s going on here.https://twitter.com/bombaybornbum/status/862394132261732353 …

      Mostly, what computers do is *mean things*. We have no coherent account of how this works; if we did, maybe we could do software better!pic.twitter.com/AMkG7kGejg

      Is there a link to the whole of this essay?

      I’m afraid it’s just a draft, currently. The stuff I’ve just tweeted is a summary, though! And do check out Brian Smith’s lecture.

      (Natural) numbers have three uses: cardinal, ordinal, and nominal. Nominal is using a number to identify a concept or thing.

      As developers we make use of numbers in all three ways. User experience is dominated by nominal use, almost to the exclusion of the others.

      Ordinal case for, e.g., sorting an array. Cardinal case when we choose to use powers of two. This sentence is a nominal number.

      Often we build additional formal structure using nomination. An interesting and common case are grammatical structures. Interesting because:

      Through nominal use of those formal structures, we can specify both computations, and concepts. That border we call a programming language.

          This abstraction allows us to specify a series of complex cardinal operations (canonically NAND) on integers to, say, deliver a tweetstorm.

          The extensive *formal* use of the nominal property of number explains the fascination with category theory. As well as the sense of humor. ៚
