  • I agree it’s not a blockchain, (although it has chain properties) but it is kinda decentralized. By convention projects almost exclusively have a single remote, and by convention that single remote is treated as an ultimate source-of-truth… But you can absolutely have the same repo with multiple remotes defined, and one could establish different schemes to determine which branches on which remotes represent what in terms of “truth”.




  • Metric and imperial don’t change the way carpenters work because in the case you mentioned of a sub-mm dimension, that’s in the 64th of an inch range. Carpenters don’t ever measure to that precision because of the fluidity of the material. Craftsman will at that point just cut to fit.

    My point with those hard numbers wasn’t that metric would make those numbers easier, only that your examples were intrinsically favouring imperial measures. Maybe it’s easier to say:

    What’s easier to figure out, 1/3 of 3cm or 1/3 of 1 93/512 inches? You can easily construct scenarios for a measure that are easy in one and obscene in the equivalent. It’s less about the notation and more about the measure. If you assume all of the initial measures are round in imperial units, then the math will automatically be easier. If your designs were designed in metric, they’ll be round to metric. If they’re in imperial, they’ll be round in imperial.

    And when this degree of precision is actually important, imperial craftsmen (engineers, machinists) already use decimal. A “Mil” is a milli-inch.

    Anyhow, again, I agree that for some very specific scenarios dealing with fractions is easier, especially when you’re doing any base 2 operation.

    I just think that you would be surprised how infrequently the issues you’re imagining would actually manifest themselves, working with intrinsically metric designs, and that you’re underestimating the number of scenarios where not dealing with fractions actually would make your life easier.


  • I understand the underlying principle, but I’m not sure if it actually shakes out that way for a few reasons:

    If you asked a carpenter to cut something to 1/24", they’d be like “what?”. Sure, the math was easier, but the result is unusable. No measuring instrument has divisions of 24ths. The person making a cut would need it in terms of 8ths, 16ths, etc. Any time saved at the initial stage is lost when they need to convert it again to a useable denominator.

    Secondly, what’s 3/32nds of 17/128ths?

    The examples you give are harder in decimal form because nobody is going to make metric carpentry designs for things that are to the tenth of a millimeter, so 1.25cm isn’t even real.

    I admit, there are a lot of specific scenarios where fractional convention is helpful. I just personally think they don’t outweigh the drawbacks.
