> Autocoding straight to embedded

I used this twenty-something years ago. It worked, but I would not have wanted to use it for anything serious. Admittedly, at the time, C on embedded platforms was a truly awful experience, but the C (and Rust, etc) toolchain situation is massively improved these days.

> Plotting still better than anything else

Is it? IIRC one could fairly easily get a plot displayed on a screen, but if you wanted nice vector output suitable for use in a PDF, the experience was not enjoyable.
