If people have notches in their hearing sensitivity at low or mid frequencies, sounds at those frequencies might fail to mask other sounds as expected. You could simulate this by applying notch filters to otherwise transparent lossy audio a

This. Your ears are not an oscilloscope. Lossy audio codecs are designed to exploit two major weaknesses in human hearing: 1. Poor sensitivity in bass and treble. See: https://en.wikipedia.org/wiki/Equal-loudness_contou

The human agent has a physical body like yours and shares your evolutionary history. They have reasons to care about things like reputation and social status. An AI agent only "cares" about maximizing or minimizing a number. It&#x

But people talking about tools usually mean tools in the concrete sense. Even very complicated tools in the concrete sense, e.g. compilers or CNC mills, only act as multipliers to the operator's ability. A consultant is an agent, not a

Calling humans a "tool" is metaphorical. Humans are not literally tools.

by mrob 2y ago
Modern AI does not act like a tool. Tools behave predictably and deterministically. They act as a multiplier to human ability, not a replacement. Modern AI is a new class of thing that humanity has no experience with.

Dark mode was normal in the early days of CRTs, when most CRTs refreshed at 60Hz or lower. The dark background made the flicker less obvious. Once higher refresh rate CRTs became common (1990s), the flicker became less of a problem and ligh

A 3dB increase is a doubling of a power quantity, but you need 6dB to double a root-power quantity (formerly called a field quantity). Sound pressure is root-power quantity: https://en.wikipedia.org/wiki/Power,_root-pow

I think a more robust approach would be to restrict the generative AI to generating summaries of book texts. First summarize every book (this only has to be done once), and then use vector search to find the most similar summaries to the pr

I found Casino Royal to be a huge disappointment. As far as I'm concerned, the whole concept of "spy action thriller" is inherently ridiculous, so you might as well go all in on the wacky cartoon hijinks and have some fun wit

You need reference materials to learn both of them. The Python example looks more like English, but anybody who assumes it works like English and tries to modify it will quickly find it doesn't work like that. The experience could be m

It's to reduce sample-and-hold blur. Modern displays typically produce a static image that stays visible for the whole frame time, which means the image formed on your retina is blurred when you move your eyes. CRTs instead produce a b

We're getting closer, but 480Hz is still too slow for a convincing simulation of phosphor decay. 1000Hz will probably be enough.

For maximum motion quality the refresh rate needs to match the frame rate. Modern gaming LCDs can beat CRTs in refresh rate, but only a minority of games support such high frame rates. For any given refresh rate the CRT will always have bet

The difference isn't subtle. This is perfectly sharp and clear on a CRT, but blurry on an OLED: https://www.testufo.com/

If I was in charge of a big corporation that still made displays, I would not want to preserve CRTs because it could hurt the narrative that modern technology is strictly superior to old technology. If people thought about CRTs in a positiv

>Isn't motion blur the best workaround to mitigate this problem? Motion blur in real life reacts to eye movement. When you watch a smoothly moving object, your eye accurately tracks it ("smooth pursuit") so that the image

The brightest CRTs were those used in CRT projectors. These had the advantage of using three separate monochrome tubes, which meant the whole screen could be coated in phosphor without any gaps, and they were often liquid cooled. Direct-vie

You're correct, but sadly most games and movies are made with low frame rates. Even 120fps is low compared to what you need for truly realistic motion. Flicker is a workaround to mitigate this problem. The ideal solution would be 1000f

For smooth and fast motion, yes. Although I don't have such fast displays for testing, you can simulate the effect of sample-and-hold blur by applying linear motion blur in a linear color space. A static image (e.g. the sample-and-hold

But the refresh rate needs to match the frame rate to get the best motion quality. If you display the same frames multiple times you'll get ghost images trailing the motion. Lots of games are locked to lower frame rates, and there&#x27

1000Hz is enough to match CRT quality on a sample-and-hold display, but only when you're displaying 1000fps content. A great many games are limited to 60fps, which means you'll need to either interpolate motion, which adds latency

It depends on the CRT. Some use steel bands wrapped around the edge of the faceplate and tightened to keep the glass in compression where it's strongest.

Only the oldest CRTs used leaded glass for the front, because leaded glass gradually turns brown on exposure to X-rays. More modern CRTs used glass with barium and strontium for X-ray shielding in the front. They still used leaded glass for

Unfortunately, the flicker is essential for the excellent motion quality CRTs are renowned for. If the image on the screen stays constant while you eyes are moving, the image formed on your retina is blurred. Blurbusters has a good explanat
