Good point. The game has really changed in terms of what kinds of programs we can write now. Perhaps it's too pessimistic to not expect these sorts of optimizing compilers soon. Sounds like a good research opportunity to me.

Ya, the central obstacle is that: 1. for simple and small graph problems, a simple vector-of-vectors adjacency list is easy enough to code up. 2. For complex and huge graph problems, the only way to get performant solutions is to tailor th

chuckke nobody buys a car because they feel like giving a billionaire money. I mean, if you can afford to spend $100k just to simp for Elon Musk, god bless you, but the rest of us want $100k of value when we pay $100k for a car.

The answer is that being a private tutor, on average, pays even less than they make now. You know how I know that? Because they aren’t already doing that. How many families could afford the salary of even one teacher?

I question whether real human beings, in a real work environment, can actually rise to the angelic level of not blaming anybody. Some guy causes you to spend 10 all nighters in a row, because every day for 10 days he moved bad code to prod

The point that we shouldn’t speculate too much about the implications of Neanderthal brain size is well taken. But IMHO it applies just as well when trying to show that Neanderthal’s language was super different from ours. We know virtuall

For all the real work going on, we practically are already extinct. There is a vibe line between doom scrolling and brain death.

True, but if we go extinct, there is nobody left to preserve our genes.

I don't quite follow where you are deriving the reflection of a vector across another vector. You seem to assume that it is the parallel part which needs to be flipped--isn't it the perpendicular part? And the GA derivation does

by rhelz 3y ago
Certainly our capacity for abstract thought is our superpower, but recall, we tried to spread to Europe for 200,000 years, and the Neanderthals always were able to push us back out again. 50,000 years ago, something changed . Maybe it was

Perhaps I would understand your point better if you showed the same derivation both using GA and keeping two books for the two separate products? Honestly, I don’t get why the geometric product is unintuitive and not meaningful: it’s just

by rhelz 3y ago
Hmmm....so basically, you are saying that you prefer to keep two sets of books, one for the inner product and one for the outer product? Its true that when you are, say, proving that two expressions are equal, e.g.: a = b you might have to

Hmmm.... if I understand your post correctly, it seems like you think the geometric product should be canceled ("cancel" as in cancel culture). And it should be canceled because it's really weird to be adding a scalar to a v

It's one possible theory, and no doubt, at the very least, it was part of the reason they died. But that's not the only smoking gun. E.g. For at least 200k years, we can tell by fossils from the middle east that we made many atte
