This is great. The pragmatic bit that makes it a bit more challenging (or, perhaps, a bit more of a search optimization problem than analytical) is that most of the cost functions are step functions. Once you need better than 10% tolerance

Get even a basic equation solver in there and I'll be a user! Have it handle units properly and I'll be a happy user. Have it be able to handle both worst-case and RSS tolerance stackups and I'll be in love.

Nope, C on 36 bit machines traditionally used 9-bit chars, packed four per word. C tends to dislike (read disallow) representations where chars, as the primitive type, do not completely tile memory; it makes things like memcpy() fuzzy, as t

Just like "metric" can refer to CGS or MKS, "imperial" can refer to... well, whatever you want. But usually in the US when we say "imperial", we mean statute miles as the mile unit, not nautical miles.

But we know that in the medium term, growth is limited to cubic; and in the long term to quadratic. Building a society that depends on a few centuries or millenia of exponential growth is designing for failure when that asymptote is reached
