I remember only one huristic: unary operators have higher precedence than others.

Do you know how many the clinic has tested since then? The ratio between the confirmed cases vs the test count seems about 3% in US, and the total tested number in US is 472 according to CDC.

It appears US is better than Indonesia in reporting, but worse than Singapore, according to their preprint [1].

AFAIK, the coronavirus test is not being conducted for people who have no history of visiting China or traveling outside, and the virus can be transmitted before symptoms could appear. Based on the article, it is conceivable that the virus could soon be found from a person who has no travel history outside US, but only when the person gets dangerously sick.

Yep. I still have a Windows machine for banking and gov websites in SK. Things got much better lately thanks to mobile apps and relaxed regulations, but I see Windows-dependency is still strong on some websites.

This is a question of the causality between the family dinners and the socio-economic indicators of a kid. Just like most of similar questions, it is healthy not to assume causality until proven there is.

IMO, having regular family dinners is just one of many characteristics of stable and healthy families.

IMO, Netflix is at the stage where it collects mass preference to produce better movies by themselves, which creates a virtuous cycle for their bottom-line -- addiction to the platform of the mass & quality production.

I would think they will start charging more if the growth stalls AND enough stickiness of the platform is proven. Currently, they are making profits and growing in terms of revenue, so as long as the founder keeps the control and the company is profitable, I think it might make sense to pursue more subscription at the cost of short-term profitability.

I would like to learn more about practical cryptographic issues, and I need some help: what are the tests that can prove or disprove stronger guarantees for cryptographic security of a PRG than diehard? A wikipedia page doesn't give me much info about which one provides stronger guarantee and in which criteria:

https://en.wikipedia.org/wiki/Randomness_tests

Also, which level of security of a PRG is sufficient for keys like this?

Much of Samsung's production happens outside SK so I don't think the influence of SK labor policies on Samsung is not as significant as one might think.

If anything, such labor policies as well as this kind of prosecution and sentencing for those powerful people would help the long term health of the country and even Samsung itself.

If you see the results, you can also find negative correlation between stroke and the density of the western restaurants (french/italian or fast foods). What conclusions can you draw out of that? I'd probably just think this is just an interesting study that can't say anything with the results alone.

Could this article explain why?

What about two? The probability would be much lower when IID is assumed?

Literally speaking, I don't know what is not true about my statement above.

But your point is well taken; it is also applicable to this article as well: maybe Go is not the game people can beat machines, but StarCraft 6 could be. Or maybe I can fold my laundry more efficiently than any machine available.

Before cars, there were horses. We humans are well aware of the fact that our physical ability is not our competitive edge.

What about Go? No animal or machine could play it as well as humans do.. until AlphaGo came along. I think that is where the sense of loss comes from.

Does anyone know what led him to be such a productive engineer? I would love to hear about his design principles and his routines.

As a South Korean, I think most of the things described here are not exactly true, but I might be wrong. Could you provide any source?

AFAIK the history of Korean educational system is the history of Hakwon superiority in adapting to new rules. A hakwon crackdown was something the gov did in 80s and failed miserably.

Also there are now very diverse channels for univ entrance. I would think some channels still allow many of those banned criteria. Maybe they cannot be used in some prestigious public ones?

Neither. It is just a rarity.

For those who wonder, the Nature article is here: https://www.nature.com/articles/d41586-019-03298-6

Given that your symptom is related to hydration, I wonder if the pain could be related to kidney stones. An internet search gives me an article that says the pain location may move as the stones move around: https://www.healthline.com/health/symptoms-of-kidney-stones#...

Could the collected DNS info be used for their own proprietary investment? I was reading a book about Koch industries and it made me think about the potential that most of the infrastructure companies could have outsized profit out of the derivative investment based on the information gathered from the business they are better known at.

Suppose a narrow field where only two human beings can understand. How could the society judge the progress of the field or the merit of a new project? I don't think it is possible to avoid collusion or groupthink in such a field and it would be difficult to differentiate the two.

So does it mean we should curb some superhuman thinking and let them explain better to other human being? I'd think so. It is all about balance or trade-off, but at some point, a field would become too esoteric for a society and it might need to slow down the short-term progress to ensure consistent long-term progress.

It seems the math field as a whole (or more specifically the number theorists?) needs more of good communicators who can link the cutting edge and more general public. The math academia could give incentives to such activities in addition to pushing the boundaries.

I was answering to the comment (paywalled by the article), and I believe a few companies do hold onto the cash when they see the opportunity, but probably not many would have the gut or the data.

Or, when a better investment opportunity is on the horizon. If an economic recession serious enough to affect good companies is looming, and if some savvy people with capital know it coming by the data or instinct, they might hold off their investment until the time comes so that the can "invest" or acquire those good companies at a better term.

The one who fails later could get the market share and monopolistic power. The void will be filled as soon as it gets created. That is how the market economy normally works.

Do you think this is an important enough issue for a Senate hearing or a bill? I honestly do not.

I have suspicion that these politicians know what they are doing and they are doing these stupid things with the fullest knowledge that the bill does not help the addicted people. Also probably they know these things don't even threaten the tech giants. Then why are they spending their precious time for such a meaningless bill?

This makes me think of McConnell gaining support or lobbying from tobacco industry. Maybe this is a thinly veiled threat or request to the tech giants?

"Health" is a loosely defined word and there are many goals and metrics. We can definitely study some metrics of "health" and study them with high confidence if the goal is well defined and it can be monitored with fine granularity. For example, if many people exercise and then the blood glucose drops for the next day, we can see its good effect, and probably it's easier to figure out what hormonal mechanism or neural pathway affect them.

If the goal is higher-level health issue, like longevity, it is trickier because of, as you said, many confounding issues. I suspect there would be cyclic causality between exercise and longevity/overall health, and it would be quite difficult to separate the cause and the effect. IMO, maybe the best way is, making educated guess based on the studies with clearer metrics.

I'd say the dividing line is how much control you have. If there is short burst of stress for the amount of work you are sure to be capable of, the stress is nothing. The problem is with the duration and the uncertainty.

There is also a genetic factor: I remember there was a gene (or a base pair?) that is called "worrier or warrior", and if one has the warrior one, one performs worse without stress than with stress whereas the worrier one is the opposite.

US median household income is about $60k, which is stagnant for about 15 years despite GDP growth [1]. The median listed housing price has increased by ~50% for the same time[2]. What could a good financial management education teach with these trends in mind?

For a newly-minted median-income household, what is a good financial decision between buying a house or renting? Buying a house with much debt and mortgage payment is risky (remember 2008?) but maybe it is a good investment until that time. Or, not buying a house and continue to pay the rent and helping someone else paying their mortgage may be the safest bet. In either case, there seems growing housing cost anyways that no financial education could help.

Maybe moving to an area where no job exists but house or rent is cheap could be an alternative that no education suggests?

IMO, financial education without considering external environment is easy. It's always like, save more and keep some cash for the risk. But what it doesn't tell people is that the risk is getting higher for the same return and more and more people deplete their income paying the premium.

I agree with your general points: this article over-emphasizes negative aspects of a few people and the picture it paints is not representative of overall planned cities, even Songdo.

Just one nit: 4855:1 came from an article in 2007 about the initial applications for an office-tel (basically a high-rise building with offices and apartments). After 12 years, I believe Songdo has a new problem of too many ongoing housing projects and not enough people to fill the apartments to be built.

The boundary between drugs and non-drugs is murky. Even refined salt, sugar, and flour could be classified as "drugs" -- your brain gets affected by them, potentially permanently, and they are hardly natural -- and even less people consider them as drugs.
