So refusing to provide service is "intolerant"? Does this only works on "protected groups", or does it work in general? How about the baker is willing to provide service to the gay…

I actually think you are more possibly to make mistakes in R than in Excel. Because in Excel you always see the results directly, and you can even easily catch an anomaly in a sing…

So you think all Google needs to do is just filtering out websites blocked by the Chinese government? Really? You have a underlying lack of understanding how censorship works. They…

Imagine this is an online discussion board for doctors, and now we are having a discussion on this topic in the news: "China is harvesting organs from detainees, tribunal concludes…

Anybody realize how pathetic it is to have this comment on the top on this website?

This is definitely not enough. There still need to be an thorough investigation into the history of the project, at least include but not limited to: 1) the internal decision makin…

This number does not mean much. In the old days, more Chinese students rely on full scholarship to study in the US. Now, more and more rich Chinese kids (mostly come with very poor…

I don't follow. Do they match faces to crimes or match faces to faces of criminals?

"if 1 in a million are criminals"? NYC population is 8.6 million in 2017, so there are only 8~9 criminals in NYC? Wow. Come on, you should give a much better estimate.

data.table can handle millions of rows easily, as long as the data can fit in the memory.

The second example should be written like this: diamondsDT[cut != "Fair", .(AvgPrice = mean(price), MedianPrice = as.numeric(median(price)), Count = .N), cut][order(-Count)] There …

"cherry picked"? There is no doubt that data.table is generally way faster than dplyr, unless you cherry pick a few use cases. The problem is that dplyr is much slower than data.ta…

"cows the population into authoritarian submission" ? I don't see this happening at all. There have been countless protests against the Trump administration, and the main stream me…

When I say another 911 I didn't mean another exact repetition, I meant another terrorist attack on large scale.

30 hypothetical death is for 1 terrorist attack. Why would terrorists only attack once?

How many are arrested because of mass surveillance captures the person criticizing Trump / Obama, Or the Republican / Democratic party?

This is a silly comparison. Terrorist can kill 30 people in one attack or even break down a whole building with a bomb. When did 30 people choke by one piece of food? And we don't …

Your assumption that AI should be compared to average human driver is simply wrong. There are all sorts of human drivers, some of them drive under influence, some have slow reactio…

It's a bs comparison. The Chinese government surveillance is purely for dictatorship, and they do put political opponents and human rights lawyers in jail at a massive scale. The N…

If the US government started doing this, there definitely will be lawsuit and most probably the government will be defeated in the court. But in China, things do not work this way.…

It's simply misleading. You try make it sounds like the value a company contributed to the society is the tax they paid, in reality it's just not.
