See the last sentence in the first paragraph: "Yang’s background is in the world of startups, and he is essentially the venture-capital futurist tech guy candidate for president."
educationdata··on To build the cities of the future, we must get out of our cars
No. Car is not just the "culture", car serves our need. If you are young without kids, it may not make much difference for you to ride a car, or take a bus, or a train, subway, etc. But if you have a family, it makes a huge pain without your own vehicle.

If the city of future requires families to abandon their own vehicle, it is not the correct city of future. Just design a better one.

educationdata··on Amazon Pulls Books That Promote Unscientific Autism ‘Cures’
No, in the cake lawsuit the owner was happy to sell the cake to the gay couple. He just refuses to make a customized cake for the wedding.

https://en.m.wikipedia.org/wiki/Masterpiece_Cakeshop_v._Colo...

"Masterpiece's owner Jack Phillips, who is a Christian, declined their cake request, informing the couple that he did not create wedding cakes for marriages of gay couples owing to his Christian religious beliefs, although the couple could purchase other baked goods in the store. "

educationdata··on Amazon Pulls Books That Promote Unscientific Autism ‘Cures’
I think Amazon's action concerns people bc it's strong position in the book market. It's very different from your own private action. I'm not saying Amazon should be forced to sell the book.
educationdata··on Amazon Pulls Books That Promote Unscientific Autism ‘Cures’
Exactly. It shows Amazon is making a bad precedent. If Amazon removes books deemed to be unscientific, does this mean books have not been removed are deemed to be scientific? Should Amazon has a science department to validate all medical books?
educationdata··on Amazon Pulls Books That Promote Unscientific Autism ‘Cures’
You are making a straw-man argument. Nobody here is claiming Amazon should be forced to sell a Book. The concern is whether it is a right thing for Amazon to do, not whether Amazon has the Right to do it.
educationdata··on CERN cuts ties with 'sexist' scientist Alessandro Strumia
This is not the point. The point is that: if your study reach conclusion A, and someone finds flaw in your research method (this will certainly happen) -> you are a *ist. On the contrary, if your study reach conclusion of opposite of A, and someone finds flaw in your research method -> this is fine because no research is perfect.
educationdata··on Taxing Uber and Lyft rides is L.A's latest plan to free up congested roads
Based on the comments here, it appears to me that many people don't understand the economy lose from the inefficiency of public transportation. 1 hour of bus transportation usually take only 20 minutes of taxi ride. It means I can save 40 minutes from the taxi ride. This 40 minutes have considerable value.
educationdata··on Microsoft CEO defends US military contract that employees say crosses a line
I can never understand those protesters. If they can sabotage military in all countries, that may be good. But they must know it is impossible. They know their kind of activism has zero effect on Russian and Chinese military (imagine Huawei employees sign a letter of this kind, which will never happen). So they are volunteerily sabotage U.S. military to help the Russians and Chineses. I'm not sure how they get their head around.
educationdata··on Paul Graham on the Transition to Meat Substitutes
If meat substitutes are pure chemical, why do you stop there? I mean why social pressure only against eating meat not against eating plants? Yes, there is a difference between animals and plants, but they both have life, right? Why don't you just eat 100% chemicals?
educationdata··on Microsoft Workers Protest Army Contract with Tech 'Designed to Help People Kill'
Not sure about this one, but in the Vietnam era, many anti-war activists were Soviet spies, or influenced by Soviet spies, or communists who have no direct connection to the Soviets but want to see communism takes over the world.
educationdata··on Nearly Half of US Female Scientists Leave Full-Time Science After First Child
What evidence do you have that current business practice that parent comment is facing and calling "sexist" is not sexist?

~ Do you have any evidence showing single dads get better treatment than single moms?

educationdata··on Nearly Half of US Female Scientists Leave Full-Time Science After First Child
I think you are wrong to claim current business practice as "sexist". Ideally, it would be nice for single parenting be as easy as traditional family, but in reality, nobody is entitled to easy life.

Traditionally, people can also help each other through big family, church and other local communities. The new generation does not want to be involved in any of these. Now they want the government and their employers to bear more responsibility to support their personal life.

educationdata··on U.S. Accuses Huawei of Stealing Trade Secrets, Defrauding Banks
In China, stealing trade secrets is called “打破技术封锁” (breaking the technical blockade). The U.S. does not even need to collect evidence through investigation. Just by reading Chinese news reports and textbooks, you will find there are lots of Chinese nationalist stories about their hero technician / scientists steal western technologies. They are literally proud of it.

I heard from my Chinese friends who work in the US universities in the field of EE, CS, material, etc.. Huawei actually has personnel monitoring their university webpages. Add working project to your webpage, Huawei could call/email you the next day (in Chinese of course) if they find something they want to buy to get ahead.

educationdata··on Ask HN: Hardware guy needs to learn web application development – what language?
Many times language is not the barrier. It is very likely it will take you less time to learn a new language than to learn a framework in a familiar language.

Personally, I found PHP is the easiest to get into web development. You do not have to use MVC or any framework at all. For other languages (python, js), web development almost always requires using a framework, which can take more time to learn than learn the PHP language. And PHP is also easier for hosting.

educationdata··on To protect kids, don’t send report cards home on Fridays
"In a review of research on emotions and moral development, the psychologist Nancy Eisenberg suggests that shame emerges when parents express anger, withdraw their love, or try to assert their power through threats of punishment: Children may begin to believe that they are bad people. Fearing this effect, some parents fail to exercise discipline at all, which can hinder the development of strong moral standards."

Here is a very good read: Raising a Moral Child. https://www.nytimes.com/2014/04/12/opinion/sunday/raising-a-...

educationdata··on To protect kids, don’t send report cards home on Fridays
Could be. Then the study should report how many were verified as abuse, how many were physical abuse.
educationdata··on To protect kids, don’t send report cards home on Fridays
I am not blaming the high false positive rate (although itself is problem). The problem is that this kind of high false positive rate has a huge impact on the quality of the study. Be aware the followed analysis does not account for the error in reporting and verification. There are simple too many noise.
educationdata··on To protect kids, don’t send report cards home on Fridays
School is not a recent invention. Public school is recent invention.

Also, there is much thought put into schooling. Curriculum (what to teach), instruction (how to teach), school administration, etc.

I am not saying schools are perfect, but claim schools are the same as jails, education is the same as torture, it's just bullsh*t.

educationdata··on To protect kids, don’t send report cards home on Fridays
It is just not illegal, it does not mean the schools or teachers are actually doing it.
educationdata··on To protect kids, don’t send report cards home on Fridays
It is strange that the study does not report raw numbers of instance. How many happened after post card release vs. not after post card release? I can't find the raw numbers of such. Only raw number of breaking down by race.

Also, "Of the 167906 calls to the child abuse hotline for children aged 5 to 11 years, 2017 (6.7%) were verified as physical abuse cases". Only 6.7% verified???

educationdata··on To protect kids, don’t send report cards home on Fridays
What is absolutely insane? The existence of "corporal punishment" or "physical abuse"?

According to the quoted sentence ("prevent corporal punishment that crosses the line into abuse"), corporal punishment is not the same as abuse. The article also says: "Corporal punishment may include pain but is not supposed to result in injury; corporal punishment resulting in injury is physical abuse."

So the line is whether the punishment resulting in injury. But it is not clear what is counted as "injury".

educationdata··on How China could dominate science
That is because the leading scientist of the lab can get lots of funding, and bc of the unique funding mechanism in China he must spend those money as fast as he can. When I was a student in China many years ago, I saw lots of high end Unix workstations in physics lab and nobody knows how to use them. Professor told me they had to spend the money...

China’s Chief Justice Rejects an Independent Judiciary

https://cn.nytimes.com/china/20170119/china-chief-justice-co...

Quote: “We should resolutely resist erroneous influence from the West: ‘constitutional democracy,’ ‘separation of powers’ and ‘independence of the judiciary,’” Chief Justice Zhou, the head of the Supreme People’s Court of China, said in a speech to a group of legal officials in Beijing. “We must make clear our stand and dare to show the sword.”

Even Apple can't read iMessage. I guess in this case they will simply force you to unlock your iPhone to let them read everything in it.
educationdata··on Transparency Report: Government requests for customer data globally
Why would Chinese government ask Apple for help when they can directly get user data from ISP and Tencent? Chinese local police can read people chat messages in real time.
educationdata··on Huawei Could Divide the World
"I think a lot of people (including me) want China to join the club of first world countries, not just economically, but also in terms of respect of human rights. "

-- Really? A lot? I don't think so. My experience is Chinese middle class rarely care about human rights issues. Most of them are extremely cold blood. As long as their own family is not hurt, they don't care about human rights issues at all. As long as they can get rich and stay rich, they will praise the authoritarian regime.

educationdata··on Economic Analysis of Medicare for All
How can they assume this will not change how everything else works?

Yes. You can say statistically we did the comparison by holding everything else the same, but it only means "statistically". It definitely does not mean in reality you can hold everything else the same. There is no way when the policy changes, the system still works as before. This kind of study is totally delusional.

A policy works in other countries does not guarantee it will work in the U.S. For one thing, U.S. doctors make much more money than other countries. There are also other many differences. How can you assume you can simply move a policy successfully from other countries without making other important changes?
