The determinant of a polynomial mapping is a polynomial, which is the subject of the conjecture. To get the Jacobian determinant, all you need to do is compute partial derivatives …

No. This is about polynomials. The assumption that the Jacobian is nowhere zero is what is doing so much of the work. This means the Jacobian must in fact be constant. But obviousl…

"At present, no language can rival, let alone surpass, Fortran when it comes to implementing long-lived, large-scale, massively-parallel scientific and engineering applications; no…

So far as we know, consciousness only takes place in biological organism. A computer isn't a biological organism, therefore the burden of proof for claiming that an LLM is extraord…

There's a reason so many cab companies have fleets of Priuses.

"Serious delirium!"

He didn't pooh-pooh anyone's careers.

"Legibility" here just means something that is visibly important/useful/scrutable/not a waste of time to (i.e. "is legible to") a manager.

This is what the field of numerical analysis exists for. These details definitely have been treated, but this was done mainly early in the field's history; for example, by people l…

This is just subdivision of Bernstein polynomials. The unifying way of looking at this is via the blossom of the Bezier curve (Bernstein polynomial). You can derive all manner of s…

It could easily be both.

The truck would come by once a week to pick up all of our dirty diapers and drop off a new set of clean diapers. The service provided a bucket with a cloth bag inside of it that ha…

With the service we used, they picked up and dropped off diapers once per week using a big truck. They also drove around to do the same for many other people at the same time. You …

What do you find confusing about the idea of a diaper service? It seems too unsanitary for you? The idea that it might cost slightly more than disposable diapers is intolerable to …

The energy saving is clear and gets better year after year as the grid continues to green. You can also line dry cloth diapers which saves a lot of energy. I never had any trouble …

They really do! Anyone who's thinking that a set of cloth diapers begins and ends with a single family has really got a pretty limited imagination.

Cloth shopping bags are a really bad comparison here. Some things working in favor of cloth diapers here are general greening of the grid, mitigating issues with electricity consum…

This study has issues. Take a closer look at it. See my other comment on here responding to someone else who linked to it.

This study has serious methodological issues. I would encourage you to carefully peruse it yourself before citing. This is far from the only issue, but the fact that someone who wo…

Oops, talked to my wife and realized I got a detail wrong: we did not keep the diapers from the service, we gave them back. And the diapers we got from the service were almost sure…

We kept the diapers from our diaper service and the covers. The washing machines used by the service are much beefier and can handle these kind of loads easily, and will generally …

Cloth diapers are good. We used them for our last kid with a diaper service and are going to do it again washing them ourselves with our next who is due at the end of the month. Re…
