> Note that functions like sin and cos have exactly the same type signature, yet it is disastrous if you mix them up. Static type checking doesn't help. I agree with you. I am hard-pressed to imagine types (where it's static an

I assume you say it at least a bit in jest, and with a good deal of sincerity. Did you ever know an interactive environment for producing Fortran code? Anything like a REPL?

We should be careful to appreciate the “types” in Julia for what they are at their essence: a way to direct dispatch of methods. Certainly the Julia compiler reasons about types in order to generate efficient code. But Julia types also affe

I really want more interfaces like this, with diagram representations of source code, and convenient and interactive plotting. Thank you! Can you speak to why a scatter plot and a line plot are distinguished using `(xs, ys, zs)` and `[xs, y

Did you ever develop a crush on someone you never really interact with, and who had no positive impact in your life? Perhaps someone who has had a less-than-positive impact? You don't know the person that well.

Seems like the rub is "The main requirement of a heterogeneous list is that it can hold any type." when I think I would colloquially say, and use as a working definition, that they need to hold different types. Also the rub is tha

This is just begging the question, I think! Transference being real requires the idea that the caregiver is a blank slate onto which projection occurs.

I'm not sure they were suggesting using type-specific sentinel values (like null and nan), but to always use null or point to a value. I like wrapping the information in a data structure exactly as you suggested, and if you never mutat

I like to remember "plans are useless but planning is indispensable". The plan is useless because of the challenge of predicting the future. But the planning is useful because trying to predict the future gets you asking good ques

I love that example of the lua error message, but aren't there non-arithmetic functions that also error? What's the message in that case? What's nice about Python's message is how compositional or "orthogonal"

You can do that in the same way that you can upscale a raster image to arbitrarily high resolutions by interpolating. In my mind, it's not just that you can zoom into vector graphics without seeing pixels. It's also that you can m

Surely you can see that rasterizing defeats the purpose of a vector graphics representation.

Wonderful example, and this is why signed-distance functions/fields (SDF) are used. The diagram in https://en.wikipedia.org/wiki/Level-set_method might help explain how such a representation can "uniformly&qu

Thanks for re-highlighting this point, and for doing it with a pun! While not directly related to the differentiability question, the idea that you can resolve spatial movement to well below the spatial resolution of pixels in an imager is

By the way, the term for this kind of biomedical measurement modality is Photoplethysmography (PPG). The HRS3300 is an example of a PPG sensor used in a few devices, including the PineTime.
