How would that be able to work? - as it doesn't write the same character exactly the same twice, with both random variation and adapting the letters either side.

I'm guessing Rushdie is the only specific case referred to in the article because they can assume that the vast majority of their audience will consider what happened to him abhorrent. However, they then slip into much more general ter

This whole discussion is rather vague from the start - the only specific example given in the article is Rushdie, but the quote I responded to was much more general. The point I made is that inciting harassment of people's children at

Okay, so it sounds like you do agree with what I actually wrote.

Who said anything about a friend-enemy distinction? I'm talking about when someone writes things which reveal that they hold values or beliefs which make them unsuitable for a role they hold.

To clarify - say a schoolteacher writes expressing their strongly held personal racist beliefs (without specific reference to how this relates to their teaching role) would you consider that a reason?

"There is a difference between valid criticism, which should be part of free expression, and this kind of backlash, ugly personal insults, putting addresses of homes and children's schools online, trying to make people lose their

An elastica curve doesn't depend on the stiffness of the material - as long as it is linearly elastic.

Both types are used - pinning and sliding. See figure 3.19 in https://www.levien.com/phd/thesis.pdf

An interesting question, since you could record the positions of the whales, but that alone doesn't fully determine the curve. I guess you'd have to also record the distances along the spline between those pinned points.

Talking of ducks, some think that the spline weight 'ducks' could be the origin of the expression 'have your ducks in a row'.

There is a neat connection between a rolling hyperbola and an elastica though: https://twitter.com/KangarooPhysics/status/14337538508177858...

Excellently integrated pun!

That's incorrect. That curve is Bernoulli's elastica, which is different from a parabola (though for small deformations they can be a reasonably close approximation).
114.
by Jarmsy 4y ago
No - it's an elastica , which cannot be represented exactly as a bezier. Raph Levien's work is a great read on this https://www.levien.com/phd/thesis.pdf and https://www2.eecs.berkeley.edu/

I'm right with you there. Hating and boycotting FB and all their products is the clear ethical choice. I sincerely hope the company goes out of business.

I'm disappointed they didn't also look at the odds of hitting someone, aside from what happens if it does. If it's landing somewhere random within an 800 ft radius, and there are 100 people within that range, how likely is it

First of all - my sympathies - it's hard enough managing this condition in yourself, and controlling it for someone too young to communicate must add a whole extra level of difficulty. What's the current thinking on a low carb die

It's funny how the two most idiotic and repulsive replies in this thread (this one and the pro-eugenics one - ah HN, you keep surprising with new lows) both include "forgive me".
