It is probably what some call "noise backfeeding" and/or signal noise egress or leaking. It is a very common problem with cable internet (docsis). The time element might be a signal drop from too many customers on the neighborhood leg. We had a tech back when we had cable at work (in a city) who joked that 4pm work break basically tanked the whole neighborhood. You may be in an area with older equipment and/or insufficient filtering or isolation. The solution at work (and home) was to get off cable internet.

because you are thinking of the whole image where smaller parts of the image will run up against non-integer values when computing the pixels. This is similar to how moire patterns appear in a picture of a brick wall in perspective: the bricks reach a limit where they start aliasing. I think this is the missing part that the earlier commenters were trying to intimate. You are confused because you haven't understood the fundamentals. No offense meant. Look at, for example moire and shannon-nyquist sampling, aliasing in general.

In other words: what you are asking assumes a perfect scenario. integers are step-wise values so an integer scaler needs to round up or down when the actually computed pixel size is 2.5 in motion this will appear jittery and when not in motion will cause e.g. a straight line to meander

I think in the specific case of an integer-scaled full-screen capture it will look basically identical, but you will very quickly run into quantizing problems with anything moving or anything that computes to a real number rather than an integer.

I think you still have a minor clarity issue, since some of the comments here and meta seem to assume the 8k screen is larger. You are talking about two identically sized monitors (e.g. 24 inch diagonal 16:9 aspect) at an identical viewing distance where one is 720p and one is 8k. "The physics" is about subtended viewing angles, which is addressed by your stipulating identical dimensions. Lead with that.

probably closest is "caught with their pants down" but doesn't quite capture the spirit of what the OP is saying as it is often used to imply wrong-doing.

Look into Host Memory Buffer. As far as I know, HMB does not work over USB, and many SSD drives use this so as to avoid having their own memory buffer. Since you are using an "internal use" SSD with an enclosure, this might be a source for your problem.

"need glasses to see" is a common thing heard, but the vast majority of people who need glasses can actually see. In a pitched battle, on a horse, the opposition would be fairly well color coded. Consider: I cannot see my feet clearly, but I can distinguish road signs at a block distance at least.

I find the question extremely odd. ("How do you recognize and remember what you can't analyse and don't have words for?") Is it even plausible that one would be able to apply any kind of analysis to something they cannot remember? Isn't recall basically an axiom of any system of analysis?

I've done that already. I can only assume you think his use of the phrase is in keeping with primes as a countable set.
Yorik
Jun 30, 2021 21:23
A quote in the Q "The hypothesis was important to prove as it would enable mathematicians to exactly count the prime numbers" is attributed to Eswaran. I am not a mathematician, but this statement stood out to me. Primes are infinitely countable (I think), but "exactly count" does not seem to use the mathamatic definition of countability. Can you comment on that?

Depends on equipment, but if that Apple device had a combo chip e.g. realtek wifi/lan that also handles bluetooth or other netwroking such as near field etc., then an Apple Watch connecting via bluetooth (etc) might affect throughput in some manner. My wife's Win10 laptop requires that bluetooth functionality be disabled to even use WIFI: downloads are in the sub 1Mbit while uploads are normal. To the question: perhaps there are other devices or protocols that share hardware that are also switching to "max performance" and competing for time.

@JeffLambert: there are a lot of sources quoted, but the author is defending her book called "War on Police." The glaring issue I see here is that using the total black population is insanely disingenuous. A truer picture would require at least an interaction requirement: stop-and-frisk, etc.

Note that hinting is still useful when you consider zooming, pinching etc.
Yorik
Oct 30, 2017 14:50
@Vun-HughVaw: If you consider that a "point" is a word for "1/72nd of an inch," then it is completely unremarkable that increasing the number of pixels while keeping a fixed inch, by necessity, must imply a larger number of pixels per point. In other words: 72px per 1in is the same as 72px per 72pts. 9pt @ 72ppi = 9px; 9pt @ 144ppi is 4.5px. "4.5 pixel type" (not really possible, since it is not an integer) is probably unreadable. When the density goes up, they must choose larger point sizes, for the type to be readable.

Quantization error will probably never go away, the magnitude of errors only get smaller with respect to the size of the signal. A high res picture of a screen door can still suffer from aliasing even at 8k if the screening pattern is small enough with respect to the pixel size.
Yorik
Oct 30, 2017 14:50
@Vun-HughVaw: I purposely used pixel units, since points must be resampled to the pixel grid. Originally at least, Windows used 72 as the logical ppi measurement (logical, since the actual inch measurements of screens vary quite dramatically). The side effect of this is that 1 pixel was 1/72 of a logical inch, which happens to be the definition of a point. This meant that 9px type is 9pts, and since an em is the point size, 9px type is 1 em. In any event, the problem that hinting means to solve is how to handle quanitzation error.
Yorik
Oct 30, 2017 14:50
What I am noting is just an expansion or explanation of what @LateralTerminal states int he very last sentence. The fact is, hinting is a trick for handling those cases where the size of the quantizing errors of the pixel grid is at or near the size of the signal (glyph) being rendered. With high resolutions, the trend is towards larger type sizes since 9opx and below is approaching unreadable for anything above 2k screen resolution
Yorik
Oct 30, 2017 14:50
@Vun-HughVaw: you are still confusing the overall resolution of the monitor with the actual bounding box of the glyph. Given a fixed physical screen size, a 9px glyph will appear smaller on a high resolution monitor, but the number of pixels available to describe a curve etc. remains the same. So in this case, the low reolution device is the bounding box. One trend these days is to masquerade as a 1080p monitor but actually be rendering @ e.g. 2k. This trick will give twice as many pixels, but then you 9px thing is actually 18px. In other contexts this is called 2x full-scene anti-aliasing.
Yorik
Oct 30, 2017 14:50
The overall resolution/pixel sizes for the output device is actually not relevant and never was, the relevant point is: the number of pixels in the bounding box of the glyph at the set size. This hasn't changed at all over the years: with the obvious exception of "retina-style" output (which is one resolution claiming to be another), 9px type is still 9px type and will benefit from hinting.

RE: Camden NJ: they may have "thrown money" at their schools via Charters etc, but that was at the cost of gutting the public schools. They were about to evict the kids from the highest performing public school and give the building to a charter. It appears that they gave up, or delayed the decision.

@Dave: just browsed some literature and I see one item that speaks to what you say: the "instant impulse" acts in a way that is different than a longer impulse "plectrum" strike. The same paper shows a pulse during the linear case that they think is a (reflected) transverse wave. I can imagine this would act as some form of dampener. One other paper though shows that the thicker the pick, the larger the initial pitch variation (upwards of 300 cents). They all settle out after about 200ms, but there is a very high quaver that contributes to dampening of the waves (gentler plucks ring longer)
Yorik
May 27, 2016 12:54
I don't see how the time of contact of the pick has anything to do with the problem. The contact time and pick flexibility is going to define the amount of initial transverse displacement, but how does the time-scale of the impulse that gets the string to this maximum displacement contribute anything?

"I would like to construct and algebric theory of Western music." This has been done, several times. Notation seems to be based on a dozenal/duodecimal/(base12) system, perhaps mainly because of base-12s ease of use with fractions (ratios).

I explained how to do tinting. The actual swatch colors used are immaterial, but if you look at a greyscale when placed, the content is tinted black by default. The reason I explained tinting is because the OP was asked to make it look like sepia. Sepia usually involves tinting the content.

Jun 4, 2015 18:22
As an aside, if you are tinting all pages, you might get a more elegant book if you simply specify a cream-colored paper. (If you still need a true white, this probably isn't an option)

I see "white and gold" when given the binary choice. There is, straight up, no black in this image. The white is accepted because it is fed into the question. The dress is objectively "periwinkle and brown". The actual blue dress is a red herring.
Yorik
Mar 1, 2015 21:45
There is no black in this image at all.
Yorik
Mar 1, 2015 21:45
while the interpretation(s) of what is going on is not wrong, this particular image has major curve manipulation. Compare the sampled colors with the photo of the "actual" blue and black dress going around. The question "is this white and gold" is part of the distraction also. It leads people to accept the light blue as "white under lighting."
