While I am posting this, i disagree with its conclusion. A seperate repo for your config is neither the only solution, nor is a particularly comprehensive one. For one, your deployment scripts, and other things that can escape the container

Generally I am copy-pasting code out of a WIP package to test out an idea as I go. So the code is already being written in a file. Or I am using Juno/VS-Code/Vim-Slime to simplify the copy-paste. Other times I have the package I a

I am guessing it is the thing where if you look at `@code_typed` you will see sometimes annotated not just with types but with `Const(42)` which shows where constant folding is occuring

The main equation may not really be anywhere near so simple as that. E.g. for the kind of stuff I do for work the main equation is something like output a vector which is the instructions for every powerplant in Texas of how much power to p

Correct. sin and cos was merely an example. Every real AD system has a primative for sin and cos. but they do not have every single operation you might ever implement (else what would be the point), and it is unlikely they will have every o

anyone one know why of the 7 AD's tried (8 including the one implemented at the start) there are the different answers? 0.4999999963909431 vs 0.4999999963909432 vs 0.4999999963909433 I assume if is some kind of IEEE math thing. given t

Occationally, there are a few places where you want arbitary high derivatives. But in general there are specialized solutions for those (though very few things implement them. E.g. Jax's JETs and TaylorSeries.jl in julia implement tayl

Correct, which is mentioned at the end of the post. I am not sure how well it generalizes, e.g. to multivariate functions that are defines as solutions of some thing like a differential equation. Maybe it does? I don't know.
