I'd bet on a bad update or configuration change. (likely one that prevents the affected systems from reaching the internet and being automatically rolled back)

That's really just photography in general. Mapping an analog input (photocurrent) to a pixel brightness.

> Are the bands too wide for this to work? For wideband filters used for stars and galaxies, yes. Sometimes the filters are wider then the entire visible spectrum. For narrowband filters used to isolate emission from a particular element

The problem with hyperspectral imaging is that it ends up throwing away 99.9% of all the light that hits your camera. It's been done for the sun and some very bright nebulae, but really isn't practical for most of the stuff in spa

That's common in high end astophotography, and almost exclusively used at professional observatories. However, scientists like filters that are "rectangular", with a flat passband and sharp falloff, very unlike human color v

Importantly, the planets aren't actually lined up nicely like on the site. Right now, Mars is ~5 times further then shown. That's why so many people were taking pictures of Mars back in January, when it was actually possible to ta

Except finding '-45 dB' is frustratingly common. Have a look at this random microphone datasheet from DigiKey: https://www.sameskydevices.com/product/resource/cmm-3125at-4... They do state the test condi

Another day, another LLM generated blog post on the front page. I'm not opposed to AI tools on principle, but why does this article exist? It's not because the author had anything interesting to say. It's not because the AI h

Just about all humor derives from some degree of suffering. Compared what the core could have done, the three deaths from the accident are nothing. Even things that are joked about often have much higher death tolls like wars and natural di

This is just a 185 stage device, but later ones would have thousands of stages, and could be chained together for even longer delays. Sample rates could also be much lower then 40 kHz as low as 6 kHz was used for echo effects.

Competition is generally good for consumers, forcing companies to make a better product then the other guy, rather then the crappiest thing people will buy.

I'm not an expert on this, but there don't seem to be any reported cases of hearing loss from sounds above 30 kHz, but there are documented cases of unpleasant effects. In any case, I'd keep some distance, just to be safe.

Easy, the natural angle of attack is determined by the elevator position. Flying upside down is totally possible with the right inputs.

Almost none of this is intuitive without hundreds of years of hindsight. The more subtle aspects of stability, such as avoiding oscillation mostly had to be determined experimentally. Then there is also the matter of actually constructing a

That's the trick, you invert the logic. If you hear the word vegan, assume the person saying it is not.

NVIDIA and one step down the chain OpenAI are making lots of money, mostly by convincing people that LLMs solve all problems. LLMs are perfect for this, super flashy, with a ton of hype. In reality, LLMs are really bad at most applications,
