Comment summary (Score 4, Informative) 35

LIGO has two 4km arms, in an L shape, Europe's version has 3km arms. They are sensitive to black hole mergers up to 10 billion light years away.
Einstein Telescope would have three 10km arms, in a triangle instead of an L-shape. 10x the sensitivity, to 45 billion light years "to the edge of the observable universe."
Cosmic Explorer would have two L-shaped 40km arms to get 10x sensitivity.

Comment Re:AMD vs NVDA (Score 1) 35

I don't know, but here's what the article says:
"NVIDIA relied on Turing and Ampere's tensor cores to accelerate an AI model using temporal and spatial data to weave in detail where it isn't. The effect is pretty convincing, but it absolutely requires NVIDIA's proprietary core technology. That by itself has limited adoption. Instead, AMD uses just spatial data, meaning FSR relies solely on information related to the current frame instead of trying to blend multiple frames together as NVIDIA does. "

It comes a little surprise then: "We think that DLSS 2.0 does a better job, at least right now, but it's not possible to give a definitive answer until a few games support both upscaling techniques and we can do some side-by-side comparisons." and "DLSS 2.0 is sharper but hardware support is more limited, while FidelityFX Super Resolution seems a bit softer, but has much wider hardware support. "

As an example, take a situation involving four investors. Annie owns shares of GameStop, and Annie and her broker have an agreement that allows the broker to lend Annie's shares to short-sellers. It lends them to Bob, who subsequently sells those borrowed shares short in hopes that GameStop's share price will fall.

An investor named Chris ends up buying those borrowed shares from Bob. However, Chris has no way of knowing that those shares have been borrowed from Annie. To Chris, they're just like any other shares.

More importantly, if Chris has the same kind of agreement, then Chris's broker can lend out those shares to yet another investor. Diane, another GameStop bear, can borrow those shares and sell them short.

In this example, the same shares end up getting borrowed and sold twice. The short interest volume these transactions add to the total is twice the number of shares actually involved.

Comment Seems Jameson tried to call "cannibals" bluff... (Score 5, Interesting) 101

  Jameson writes that the whole thing started as a joke, and that he wanted to see if cannibalism was a real thing after one of his guides started telling him about cannibal tribes in the area they were traveling in.

“I sent my boy for six handkerchiefs, thinking it was all a joke, and that they were not in earnest, but presently a man appeared, leading a young girl of about ten years old by the hand, and I then witnessed the most horribly sickening sight I am ever likely to see in my life. He plunged a knife quickly into her breast twice, and she fell on her face, turning over on her side. Three men then ran forward, and began to cut up the body of the girl; finally her head was cut off, and not a particle remained, each man taking his piece away down the river to wash it. The most extraordinary thing was that the girl never uttered a sound, nor struggled, until she fell.

Until the last moment, I could not believe that they were in earnest. I have heard many stories of this kind since I have been in this country, but never could believe them, and I never would have been such a beast as to witness this, but I could not bring myself to believe that it was anything save a ruse to get money out of me, until the last moment.

The girl was a slave captured from a village close to this town, and the cannibals were Wacusu slaves, and natives of this place, called Mculusi. When I went home I tried to make some small sketches of the scene while still fresh in my memory, not that it is ever likely to fade from it. No one here seemed to be in the least astonished at it.”

nerf
To weaken or make less dangerous. Taken from the "Nerf" brand name, which makes sports equipment toys out of a soft foam (e.g., the Nerf football is soft foam rather than the hard leather of a real football). Used frequently in the context of computer game balance changes.
