My takeaway is that it draws a lot more power than you'd expect, thanks to the incandescent light source, and unless there's quite a lot of airflow over the sensor, it'll exhibit self-heating at any poll rate under every ten minutes.
You could imagine a deep-infrared mission (longer wavelength, to soften the alignment requirements) launched into deep space (Jupiter+) where both the solar wind density is lower (reducing space weather perturbations) and reduced solar flux would reduce heat loads on the structure, (objects in Jupiter orbit get 3.6% as much light as in Earth orbits) making cooling easier. An interferometer design would also improve resolution. A not-widely advertised feature of the JWST is that, due to the same Rayleigh limits, its far infrared modes have dramatically lower resolution than its near infrared camera. A problem with a 6 meter mirror, less of a problem with a kilometer mirror.
Ceteris paribus, normal trees will always outcompete fruit trees because they don't have to waste any energy on fruit, and use that instead on trunk height, putting fruit trees in their shade and, eventually, starving them to death.
You can, of course, maintain an orchard of fruit trees, manually removing competitor species, but then we're talking about stationary farming, a technology that Plains Indians did not have ten thousand years ago.
Grazing animals can prevent grassland from reforesting by eating the tree shoots, but they can't knock down mature trees. There is some evidence paleoindians would burn down forests to expand grasslands. https://en.wikipedia.org/wiki/Great_bison_belt
Thus, in some parts of the US, you can stand on a hill, look out at miles of apparently untouched land without a single permanent structure, but is as artificial and manmande as a golf course, crafted from thousands of years of invisible labor.
Carrying long guns is legal on all BLM land. Discharging them may be restricted in some areas, though.
In 2003, PV panels were a pretty darn mature technology. The technology was decades old. Modules cost about $5 a watt, one twenty fifth the price they were in 1975. More than two gigawatts of them had been installed worldwide. (Millions of panels!) No way could they fall in price by half, right?
Surprise. By 2010 another 38 gigawatts of solar had been installed, and the price per watt was down to $2.32. No way could they fall in price by half again, right?
Surprise. $1.02 per watt in 2012, and another 61 gigawatts installed. $0.52 a watt in 2017. $0.26 a watt today.
Just in 2022, the world installed 86 times as much solar as existed on the entire planet in 2003.
If you build a lot of something, it can get very cheap indeed.
This is also the problem with Charles Stross' Nightmare Stacks. The concept was kinda funny in 2004, but by book number 10 it just gets tedious. The reader cries out, What is the point of all this, and Stross answers with a shrug.
Draft, Sketch, and Prove from 2022 does something like this: https://arxiv.org/abs/2210.12283
The height is nothing much, but the main factory is 2,607 ft (794 m) along the longest dimension.
Geometry problems have the nice property that they're easy to generate and solve mechanically, but there's no particular reason why a vanilla Transformer LLM would be any good at them, and you can have absolutely huge scale. (Unlike, say, the HumanEval benchmark, which only has 164 problems, which resulted in lots of accusations that LLMs can simply memorize the answers)

The CARES Act passed the Senate unanimously. If Trump caused inflation due to profligate spending, he did so with plenty of help from Democrats. He couldn't have stopped it even if he wanted to, that's far past the veto proof majority.
>In the case of ImageNet, the current state of the art accuracy is obtained by Facebook AI’s weakly supervised ResNeXt-101-32x48 model. It delivers 85.4 percent top-1 accuracy, outperforming by a significant margin the recently published EfficientNet network. . The model is pretrained on one billion public Instagram images, which contain 1,500 ImageNet-related hashtags.
The problem is that operating a two sided marketplace connecting small makers to customers just really sucks as a business. Tons of churn, intractable problems with quality and fulfillment, having to pay for a lot of customer service agents who fundamentally can't solve any problems, since they don't actually work for the person who makes the stuff, and can only hit the "refund" button.
Etsy has every reason in the world to want to get away from small sellers and move to high volume manufacturers, (who have actual QA and customer service departments, which a guy hand carving chess pieces in his basement doesn't have) and nothing to stop them. So the obvious thing happens.
(Except then you're competing directly with Amazon in its area of greatest strength, which historically has been corporate suicide...)
In response, they updated corporate policy so that you don't have to buy anything to occupy a chair: https://www.eater.com/2018/5/21/17375806/starbucks-no-purcha... https://stories.starbucks.com/press/2020/use-of-the-third-pl...
Predictably, every chair is now occupied by a sleeping homeless person.
So now their choice is to either remove all the chairs, or potentially be mean to someone, and receive a firestorm of criticism. You can see which one they chose.

There's some speculation that a net trained for more epochs on more data learns to pack more information into the weights, and so does worse when weight data is degraded.
What does Jia think "CCTV" is, exactly?
A research program for EPFCG pure fusion weapons could be quite small, only requiring a few hundred people and little equipment that couldn't be manufactured indigenously. Test explosions could be done at the kilogram scale, producing no radiation detectable from orbit or seismic effects, then easily scaled to kiloton yields.

It's like analyzing a Swiss watch if the back was welded on. You could send it though a shredder and analyze the fragments and work backwards to determine the size of the gears. But it's impossible to shred just one watch-- you have to shred a hundred thousand at a time, which are inevitably a complex mix of different watch models each with different minute lengths and hour durations.
Something I have felt is undertaught in introductory biology is how unknown human cells still are! No textbooks wants to list off a thousand proteins with "function unknown" next to them, after all. But to surprisingly large extent it's an undiscovered country. Just in the last few years we're discovering entire new species of RNA! https://www.science.org/content/blog-post/enter-glycornas
One fun feature was you could shut off your suit power to go into a stealth mode. This turned off all the HUD elements, and, amusingly enough, turned off most gameplay noises (the explosions and bullets whizzing by) because, in-universe, all those noises are generated by the suit computer, because space is silent!
Yep. https://en.defence-ua.com/weapon_and_tech/drone_carrier_quad...
The drone carrier also acts as a radio relay, the other big thing limiting FPV range, since they both have to use low gain omnidirectional antenna and also operate very low to the ground, which is terrible for reception range.
