I posted an example. y=cuberoot(x^3) and y=x should give different derivatives at x=0 in, I'm guessing, all autodiff approaches you'll get your hands on.

It's good to question what we teach. Like I never learned any methods for computing a square root, to arbitrary precision, whereas my parents did. But autodiff doesn't replace symbolic differentiation. Consider the derivative of c

I look at https://en.wikipedia.org/wiki/Formal_system and I don't really see much resemblance to how mainstream programming languages are defined. Some mainstream programming languages do not even a formal grammar

I thought about using `[]`or `indexOf` as examples of operations, but my question still remains: what is implicit about it? It's part of the public interface of `List`. Not at all like the private members of an object, which I think wa

This conversation reminds me of https://en.wikipedia.org/wiki/Expression_problem . I don't understand: "but the existence of the data structure implies that some operations must exist." Grounding it out

Unless your camera is a 3CCD camera, then CCD cameras usually have lower color resolution than luminance resolution, too! https://en.wikipedia.org/wiki/Three-CCD_camera https://en.wikipedia.org/wiki&#x2

The process seems fairly DSP intensive. If I recall, the IQ modulated color signal would leave a dot pattern in the luminance signal. I wonder how many frames it could process a second, if written in BASIC.

One thing missing from this rethinking, as far as I can tell, is names. You can't move pointers between different processes in general, because each process has its own "memory address namespace". But an absolute path generat

I don't disagree with you, but I think your statement is roughly like: all ordinary composers are writing music theory, or all ordinary language users are doing linguistics. Math is a way to add structure and understand the activity th

The microarchitectural side-channel attacks that have received a lot of attention lately really challenge the idea of a "sandbox". Also the poster said that webpages shouldn't be blank without having, not that they should b

Thanks to distributed version control, you can commit all sorts of trash in your own branch while figuring things out. These commits should not clutter the project source, though if you like hoarding data like I do, you might still preserve

The same trick is used by some oscilloscopes for high-time-resolution sampling of periodic signals. I wonder if they also average the same phase-out shift multiple times to reduce noise (improving the bit depth of a single frame).

C also doesn't have a standard package manager. I think that's the big problem. Built-in functionality is less important if you can easily use packages.

I might be missing the point, but from a quick glance at the article, it's about geographic location, and not race. Is there some second-order effect?

Do you mean they are simpler to use? Because those are just models of parallel computation. A little like saying Turing machines are simpler than python.

I understand and appreciate striking a balance between precision and a good story. But I thought in this case, perhaps this was a big deal. I thought one of the reasons why 2D graphics and 3D graphics are so different is because of ... is i

I am not sure if I understand the objection. Is that that you don't agree with the use of "2D graphics" and "3D graphics" to mean what they mean in the article?

"Without getting too into the math weeds, at a high-level, we call approaches like Bezier curves and Hobby splines implicit curves" I don't think of Bézier curves as implicit in any way. There's an explicit equation for

Is it true that plotters were the first graphical device to be controlled by computers? before oscilloscopes? Doesn't really make a difference to the point in the article. Both are "vector" devices. But I'm curious about

Thanks for pointing this out. I can't think offhand of an example to illustrate when you would like this "call back" functionality in a way that you can't anticipate when you design the component object. Do you have a ki

That doesn't sound right. What about all the other websites with ads, like recipe sites, guitar chords, porn, diy, etc.? or apps on the Google play store with ads?
