This would be fair if she wasn't arguing that the credibility of healthy skepticism shouldn't be tarnished in science. "Climate believers" attack her credibility, she defends her credibility, but her arguments are invali

Academia has officially decided that it no longer needs science, it needs populism. You won't get funding anywhere and a journal won't publish you. Your peers will ostracize you. Skepticism doesn't need to produce theories or

Perhaps you missed her point about selection bias? Only models confirming climate change can be published, any analysis is just going to confirm that. It's unfortunate because climate change could be happening, but we aren't going

I think the worrying thing is that it's not hard to believe, she's pointing out the breakdown of the scientific process. She cops a lot of flack and hysteria, just for raising reasonable doubts! If climate science is solid, then i

That's ridiculous, why would you need to do a MATLAB implementation after writing it in C? Do you even know what MATLAB is? Do you even understand what abstractions are? If I wrote something in C, I understand it on the MATLAB level. T

The gold standard is a great example of a disagreement - you cited a group that is probably dominated/biased by the Chicago School of Economics, and even then there is no real consensus on anything there. Economists are a lot closer to

The problem is when it criticizes you for criticism. I for one would be happy to know that the other side of every point is properly represented. A scary one is climate change, it is now no longer palatable to question whether it is happeni

Forgive my ignorance: What actually makes it hard to predict a chemical reaction? Can't we empirically deduce them from quantum mechanics?

You had suggested to learn an algorithm in a different order then what you've just written, that's why I suggested it was incorrect. (You put a MATLAB implementation after a C) Computer science is key to all of this, understanding

HFT having a lot of volume is irrelevant, what matters for Julia to be prevalent, is to have a lot of analysts use the toolset. You should measure the amount of analysts working in HFT vs those not working in HFT. Furthermore - HFT is perha

Universities have a vested self interest in controlling who can join a profession, they would prefer it if every worker everywhere needed a degree. Just look at the slow assimilation of vocational studies into uni courses (stuff like wine m

I spent about 2 years reading in my spare time, learning, trying to understand the world and markets in general. All the while applying for jobs. You end up getting a good feel for the job market, what you're actually lacking, what peo

Left to work in equities after 5 years of software dev. I find the work much more stimulating mentally, as you learn about the world and how business works, not just abstractions. Luckily there is still a lot of use from my old skill set, a

You make a distinction between consensual supply and non-consensual supply, but you don't do the same for demand? When prostitution is legalized, the distinction then exists for demand. What has to happen for this to increase trafficki

That's your prerogative and fair enough. Thankfully, GMO will thrive without your support and produce better food to feed the world.

He was right, you implied paying for the news removes the manipulation, which is a ridiculous notion.

Fair enough, there is a slight bit more to the buffet bet than I trivialized. The short portion of the hedge fund will have been losing as we are in a bull market. The full length of a cycle should see this effect reverse (and indeed 2008 s

They only need to go as far as to obfuscate the market data this was derived from, so they don't have to pay exchange licencing fees. It doesn't have to have an exponential time complexity on decryption to qualify as 'encrypt

They could just be normalizing every data point to be between 0 and 1 by dividing by the range. That's a homomorphic encryption.. it passes your weird assumptions. I don't know why you're harping on about sound encryption, th

In his case, these were 5 funds of hedge funds. Which underneath could be much more than 20 funds. You're also forgetting how much the compounding of the fees can cost, and you have two layers of them. This could easily make the S&

The data is homomorphically encrypted, meaning you can do operations (such as add and subtract) on the ciphered message and it will also perform them on the underlying data.

Your constraints are rather simplistic given the people behind this. It is possible, that all of the factors you've just described, are encoded in the data set.

Buffet's wager is a trick, which works on simple people who don't understand statistics. When you take a group of hedge funds, they end up being a very good proxy for the market. At about 20, they will be almost indiscernible. So

The key property that you should be testing for is dependence. It would be surprising if you could identify anything in the descriptive statistics, that would make this all child's play? I can't imagine any serious data scientist
