So, just to illustrate. A "vaccine skeptic" is generally considered to mean someone who is skeptical that vaccinations work at all. This is very different from having specific concerns about specific products, like the COVID &quot

Sorry but you're missing the forest for the trees here. The locality of a bezier, even with symmetric constraints, amounts to the fact that the user's specified positions (the endpoints) and tangent directions are preserved exactl

I wrote the article :). To clarify, I meant B-splines _lack local control_ like Catmull-Rom splines, not that the latter is an instance of the former. Though indeed, all cubic splines are just cubic polynomials. I disagree with your charact

As the post says, beziers are everywhere so we are stuck with them. It's worth trying to improve them for that reason alone. Additionally B-splines (like Catmull-Rom) have the issue that moving one point affects a larger area of the sp

Yes, a linearly parametrized line.

The C1 continuity you refer to is relative to the parametrization t=0..1 per segment. This is useless in practice. For e.g. animation purposes, you need to reparametrize to arc length which destroys the apparent C1 continuity.

Most of those rules are copes, really. Placing points at X/Y extremes is by itself useless because beziers are rotation invariant. i.e. If that's the best place for the control points, then by the same argument if you rotated the

If you like that, then try this. Take a row of pascal's triangle, add a zero in front (shift it to the right by one place), and divide it by the row below it. 0 1 4 6 4 1 / 1 5 10 10 5 1 = ... From this you can

You can try to make the WebGPU API more declarative, but the issue that you still run into is that individual draw calls and passes are a poor abstraction level to express modern rendering in. To reach the quality of a modern PBR renderer w

In 2011 the iPhone was ~4 years old and iPads were ascendant as the only tablet game in town. Google was still playing catch up with Android as a knock-off, having just debuted Android Honeycomb. The actual topics are: - the Apple campus th

Asm.js was never needed as a legacy mechanism, as it was just a compilation target for native code. There was nothing that it needed to remain backwards compatible with, all asm.js code was new code. https://acko.net/blog&#x

Hm so not only is it possible to manipulate scores on HN with weird scripts, but mods only noticed this when users pointed it out in this instance, with no automation or logging there to detect something like this? Do you suppose motivated

It's not that AI can't convince a novice that what comes out is passible. It's that experts in a field generally agree that what comes out is insidiously hollow garbage. This isn't a "semi-religious" belief. It

Homework assignment: make a bode plot of the convolution filters [1 1 1] vs [1 2 1]. Which one turns +1, -1, +1, -1, .. into all zeroes? You ought to know this because the fourier transform of [1 0 1] is a cosine of amplitude 2 on the compl

A binomial is exactly equal to a repeated 2 sample box blur yes. That's exactly how you construct pascal's triangle. For filter sizes > 2, box blurs are ass.
