> I fail to see how it's wrong. If you call Math.sin(x) it will return a numerical approximation of sin().

Right. Now what's being argued here is that instead of measuring an angle X, calculating the sine of X, and then (probably) rounding the result to a convenient decimal approximation, we should measure an angle X, round it to an angle Y with a convenient non-repeating decimal representation, and calculate the sine of Y. (That's the whole point of Mansfield's and Wildberger's analysis of the tablet; that it was a trig table that only gave answers for angles with convenient answers, rather than, as modern trig tables do, giving it for all angles.)

So instead of measuring an angle as 29.88 degrees, calculating the sine of 29.88 as 0.49818510533, then rounding to 0.4982 or whatever, we should instead calculate the sine of 30 degrees, and get the wonderful totally accurate "exact fraction" 1/2.

1/2 is totally accurate representation of the sine of 30 in a way that 0.4982 is not a totally accurate representation of the sine of 29.88, yes... But 0.4982 is a much more accurate representation of the angle you've actually measured.

From an engineering point of view (which offhand seems like the only one where accuracy matters), normal trig is obviously, obviously better than rational trig, because normal trig is more accurate in the ways that matter. The more sigfigs I have in my measurement of my angle, the more decimal places I can leave in my numerical approximation of the answer. It may always be inexact in a way that 1/2 is not, but it'll also always be exact in a much more important way. :)

> Such as? 60 has more prime factorizations than 10

So it does, but that's not the claim being made. Rather, the claim was:
"We count in base 10, which only has two exact fractions: 1/2, which is 0.5, and 1/5."

To which one might note that:

1. All fractions are exact, by definition. 1/3 is an exact fraction; it's exactly 1/3, in exactly the way 1/2 is exactly 1/2. The fact it's decimal representation is repeating does not impact this.

2. Mansfeld apparently means "fractions with terminating decimal representations" when he says "exact", which is a weird and non-standard usage. But even so, you can construct tons of fractions in base 10 that have non-repeating decimal representations, like 2/5ths, or 5/8th.

3. Possibly he means "...which only allows you to construct two fractions using a numerator of 1 and a denominator consisting of a number smaller than the size of the base which has non-repeating decimal representations..." (which would be a pretty weird thing to focus on) it's still wrong; it's missing, eg, 1/4th.

4. Finally, he reckons that in base 60, 7/60 + 30/3600 aka 1/8 aka 0.125 is an "exact fraction". That sort of factorization is legitimate, but obviously if that's an exact fraction so is 2/10 + 5/100 aka 1/4th. Or come to that, 6/10 aka 0.6.

In short, the claim is gibberish. It's using a phrase with no clear definition in a way which is internally inconsistent. There is no way that 1/8th is an "exact fraction" in base 60, but only 1/2 and 1/5 are "exact fractions" in base 10.

(Also, you're using the word "irrational" wrong.)
Has there ever been a "ancient tablet unravels secrets undiscovered" that contributed to science and not history? I think everyone can safely eliminate this sort of thing in a Bayesian sense.
There have been cases where you can't tie products together if you're considered to have a dominant market position. See e.g. https://supreme.justia.com/cases/federal/us/473/908/ In this case, a minicomputer manufacturer was deemed to be prohibited from refusing to sell an OS to a clone manufacturer. Long time ago and I suspect it would not go the same way today if Apple were to refuse to sell its OS to a clone maker. (And, yes, Hackintoshes etc. but they've never reached this level of the legal system.)

It would certainly make it more common. The cost in American soldiers is the main thing that slows down the US from starting minor wars: the population are not tolerant of losing soldiers.

Other countries are more willing to lose soldiers but refrain from war for other reasons: the economic cost, fear of losing, loss of standing in the international community, or simply having no enemy they particularly want to fight.
This seems much broader than diversity, it's really just an industry problem.

"It's just a de-facto commercial zoning grant to all residential areas"

Sure, thats kinda what it is. I'd argue that this isn't a bad thing though.

The solution that cities should take is to try and lower the cost of commercial zones and commercial property.

Airbnb and similar companies exist because these things are expensive and there is an arbitrage opportunity.

The best solution is to make these things LESS expensive so that consumers can benefit.

These silly laws on zoning, ect are extremely detrimental to consumers and should be removed. Airbnb and friends are just helping us push the needle so that these terrible laws are either eliminated or rendered de-facto unenforceable.

If you think rent prices are too high, then let's make the government allow us to build more houses, so as to solve the root of the problem.
Downvoters: this is literally true. Quote from Nixon policy chief John Erlichman, also in the sibling comment's link:

"You understand what I'm saying? We knew we couldn't make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin. And then criminalizing both heavily, we could disrupt those communities," Ehrlichman said. "We could arrest their leaders. raid their homes, break up their meetings, and vilify them night after night on the evening news. Did we know we were lying about the drugs? Of course we did."

I'm no optimisation expert, but I'm wondering if the FMAs are slow because the result of each one is dependent on the previous one? The dependency on the result may mean that the processor can't pipeline the operations. Could it be faster if the two chains of FMAs on either side of the division are interleaved and use different registers?

z := x * x

z = z * fma(fma(fma(fma(P0, z, P1), z, P2), z, P3), z, P4) / fma(fma(fma(fma((z+Q0), z, Q1), z, Q2), z, Q3), z, Q4)

z = fma(x,z,x)

No, that isn't why. I worked in insurance. Not homeowners insurance, but I had a certificate and processed claims.

The reason is that most human settlements occur in flood plains because we cannot live without water. We drink it. We bath in it. We irrigate crops with it. Flood plains have fertile soil. We use rivers and oceans for essential cargo transit.

Insurance is about risk management. It is a form of betting. And there is no bet here because there is no question of if it will flood. The question is only when will it flood?

That's a fool's bet to say "I will pay you X amount of money if it floods" when it is guaranteed to flood sooner or later. That amounts to charity, not insurance.
That's a strong possibility, as I have definitely come to associate programming with every negative emotion over the past few years.

The problem is that the person who judges the probability at 1-in-500 doesn't have any skin in the game.

The judgement of the US meteorological office affects where people can build houses and how much they pay for government insurance. Homeowners have a strong financial interest in underestimating the probability of a severe flood, so there is likely subtle political pressure applied to the met office assessments.

For a more accurate assessment, the government should buy a sizeable insurance policy from several reinsurance companies and use it to calculate the implied probability.

I wish the author took more seriously the warnings around patient health and safety. Yes, they may not apply to his particular project, but that doesn't make asking about them useless. To take past abuses lightly undermines his overall point.

It's done precisely to avoid a situation like the way he delegated responsibility to his PI: "Dr. W had vaguely hoped that I was taking care of it. I had vaguely hoped that Dr. W was taking care of it." The review board shouldn't make vague assumptions about something as critical and necessary as ethical study design.

It seemed like you were enumerating things that would be considered a cost, as if to imply something like "my costs are so and so because I need to afford X and Y, and my rate is based on my costs". Now that I'm reading it again, I guess it's indeed not the most obvious interpretation.
I think the android market has proved that there are a lot of users who don't pay attention to that. Otherwise we wouldn't have so many comments and stories about the lack of updates or how long it takes vendor X.

I'm just thinking about your average person who goes into at Best Buy or cell phone store and wants a new android phone. Given to similar phones, one with the extra hardware and the other cheaper, if they don't see the point they'll probably go with the cheaper one.

If they got to use software only AR stuff on their previous phone that may change that decision.

Or maybe the first one wasn't successful yet, or you realize your upside is capped, and you've identified an opportunity that will be potentially more lucrative or have a smaller downside risk. Changing what you're doing doesn't necessarily mean you can't make the original plan work - it might just mean you came up with a better place to put your effort.

One of my favorite business stories is that of the Nintendo Playing Card Company of Kyoto, whose CEO came to the US to visit the US Playing Card Company. He realized that even if he captured the entire world market for playing cards (this is before MtG) he still wouldn't have a very big business, and set out to find something better.

If you sample the waveforms at 192khz you are still sampling lower sound frequencies at a higher rate which does produce a better quality sampling of the waveform. All digital audio looses information from the original wave that is between the sampling times. You will not have a pure sine wave in digital format with this nethod of sampling.

Stop confusing frequency range and sample rate. Its such a fundamental face palm. Nobody is saying listening to sound at a frequency above 22k is improving anything.

> Such as? 60 has more prime factors than 10, and therefore using it as a numeric base will result in you encountering fewer irrational numbers. You really can't argue against that.

Actually, I can argue with that. Irrationality is a property of the number, not the representation. An irrational number cannot be written as a terminating "decimal" in any base. And, of course, a rational number can be written as an integer fraction in any base.

https://math.stackexchange.com/a/625481

EDIT: Ignoring, of course, doing silly things like saying pi is rational in base-pi... Which I think deserves a spot in some circle of mathematical purgatory. Also, I wonder if every number except pi and its multiples are non-terminating in base-pi...
“YOU LET PEOPLE SIGN CONSENT FORMS IN
PENCIL, HOW CAN YOU JUSTIFY THAT?!”

The funny thing is, contracts are legally binding agreements, whether they are verbal, scribbled on a napkin, signed in pencil, pen or blood, and whether the signature is an easily forged 'X' or elaborate calligraphy. Consent forms are a slightly different use-case, but I think the premise is the same: to show a meeting of the minds.

Knowing this, the pencil signature actually protects the patient more than the institution, since the patient could theoretically forge a revocation of consent by erasing their mark. Meanwhile, ink isn't as binding, without some sort of objective third-party official (e.g. a notary public, beholden neither to patient nor to institution) serving as formal witness, further validating a non-forgery, in the case of a simple 'X' or erasure thereof.

In practical terms, one solution to render the pencil signature binding would be to create a tamper-evident photocopy, with fraud-marks like a UUID moire pattern sprayed by an ordinary desktop printer, for each serialized document, readily detectable in the photocopy but permanently printed into the background of the form (e.g. yes, this is a photocopy of the same piece of paper, and the forger failed to notice the lightly tinted pattern, when erasing their signature), and retain the pencil copy, to ensure a match. In the event of an erasure, the paper might show an abrasion, and the photocopy would act as a snapshot/backup.

Meanwhile, it should be possible to access existing, archived, historical questionnaires and actual clinical diagnoses from normal records, in a de-identified fashion, and compare results, no?

Am I misunderstanding the goal of the study? Didn't he want to compare the assessment of the survey, with actual patient dispositions, and leave the rest of all treatment untouched, undisturbed and otherwise normal? Ask the questions, do the rest, same as ever, but analyze the opinion formed by the score of the answers to the questions, with the opinion of the professional caregiver beyond the scope of the simple Q&A exam?

As to your other stuff, I don't see the point in continuing since it's so subjective. On any feature which Apple clearly copied and improved, your answer is "whataboutism" to trace the lineage and claim long long ago, the seeds of it came from somewhere else. History for you is a long line of incremental, but uninteresting improvements, punctuated by Apple's adoption, which somehow defines a clearly new thing. When Apple makes an improvement, it is not diminished by the fact that other people had worked on something similar and that it's lineage can be traced as accumulated incremental improvements.

But somehow, for everyone else, history diminishes their achievement.

For me, the history of product development is one of hundreds or thousands of actors, researchers, and scientists making publishing incremental improvements that stack. People who diminish the work of others, try to hog all the credit by rebranding the achievements of others, and fail to give back are parasites.

And for the record, I am not an Apple hater. I have a maxed out Mac Pro on my desk, I've owned every Apple product you can think of, including standing in line for one of the very first iPhones sold. I have carried almost nothing but iPhones, and my primary mobile computer is a Macbook pro with touch bar.

CRITICIZING a company's magical reality marketing and the inability of its cult-like fans to admit criticism of it, does not amount to hate.
