Isn't the only difference between rotors, as defined in this article, and quaternions the sign of the second 3d component?

And this only happens because the planes are defined as "xy", "xz" and "yz", rather than the more consistent "xy", "yz" and "zx"?

If you just changed the definition of the planes at the start of the derivation, it seems you would end up deriving the exact same operations as you would use with quaternions? I'm not sure if there is a good argument for not doing that.

Math on Wikipedia is just absolutely atrocious.

I mean, no, they didn't actually occur, that is the good part.

That doesn't let Ross off the hook for attempting to make them occur.

Because there was no need to, the other charges were enough to put him away for life.

There's really very little reason to doubt he did it, either.

If Bezos tried to have six people killed, then yeah, he should be in jail.

The cost is the countermeasure, by design.

So: Short a large amount of bitcoins, 51% attack until value plunges, earn massive amounts of money.

Of course, the problem with this is that there is no exchange that you can trust enough to actually do this.

There are many more ways to make money off a 51% attack than just altering transactions.

> If a big crypto-community notices an attack, the cost of a 51% attack would rise

Would it though, really? Why?

On the contrary, someone performing a 51% attack can and will freeze out all other miners, leaving them operating at a pure loss. If the attacker manages to keep up the attack, he will be able to bankrupt the competing miners, forcing them to turn off their hash power, and thus lowering the cost for himself.

WebGPU is a simpler API for doing modern rendering, with less tradeoff.

OpenGL is not simple if you want to actually do useful things with it.

I mean, that is exactly what WebGPU is, so I am not understanding why you are so determined to complain about it.

And it became increasingly less of a good fit with each one. By now, it is ridiculously mismatched to the task it needs to perform.

Just leave it to die.

Why would that make things better, rather than the fairly obvious "worse"?

What's so "surely" about it?

That API is under development, it is WebGPU.
