References are not made to learn from, they are made to refer back to. If you look at the URL you will see that this reference in particular is on the page for CS229, which lists knowledge of basic linear algebra as a prerequisite. I really don't think this was made with the intention of anyone using it to learn linear algebra.

Just to be clear, unless you're in the margin account beta, "free-riding" is impossible in Robinhood, so users will never be breaking any day trading rules.

>Day trades can occur in a cash account (only) to the extent the trades do not violate the free-riding prohibition of Federal Reserve Board's Regulation T. In general, failing to pay for a security before you sell the security in a cash account violates the free-riding prohibition. If you free-ride, your broker is required to place a 90-day freeze on the account.

>the concept of "dinosaur" becomes nothing more than a fanciful way for paleontologists to come up with predictions about which fossils they will discover next.

I'm having a hard time understanding this criticism. What use do we have for the concept of "dinosaur" other than as a means of predicting future discoveries and building a predictive theoretical model for our environment?

If you are in a MMJ state it shouldn't be too hard to find a clinic with edibles or pills no?

Sure, maybe those facts imply that developers at Amazon have it worse than developers elsewhere, but I wouldn't exactly characterize any of them as Amazon being "terrible" to employees.

I can't . Can you?

>These persons life aren't at risk because they can't express opinions, isn't that what is meant by FoS ?

No

The idea of intuition is explored in psychology through Dual Process Theory. See "Dual-process accounts of reasoning" below.

Kahneman and Tversky spent a good deal of time trying to identify the major heuristics employed (and biases caused) by the more "intuitive" of the two systems used for thinking.

(You may note that at the time this paper was published there was no concept of Dual Processes and the phrases "System 1/2" are never used.)

Without self-driving cars, there's not a good way to have contract drivers who can just work whenever.

In this scenario, Uber should be able to maintain their own cars at a lower cost than individual car owners can, due to their scale. They would also probably be able to buy the cars for less to begin with.

Keeping in mind that Hypercar would have to pay car-loaners at least the amount that the car loan is costing them in maintenance & depreciation (or else who would loan their car), Uber would come out ahead.

Maybe in the short-term, this Hypercar company could rely on car-loaners to underestimate maintenance/depreciation costs but surely that would only last so long.

I think the fact that they are paid less, in the context of the video, implies there is less demand for them (probably much less as I assume they are also in shorter supply. Could be wrong about that though). If there is less demand, and their value in this context is their appearance, that means their appearance is seen to be less valuable in impressing customers. Hence, the conclusion that black people are seen as less good looking than white people.

I don't actually know how iOS deals with this, but judging by the fact that iOS says "turning on wifi will improve location accuracy" when wifi is off makes me think it's really off for all purposes.

It could also be said that mechanical watches are rubbish for keeping time compared to their digital counterparts. Always gradually moving away from accurate timekeeping, they must be rewound to keep proper time. They don't sync with the official time distribution services so are not guaranteed to be accurate.

Mechanical watches don't move continuously because movements of the hands are controlled by gears with a finite number of teeth. As for the "simulacrum" comment, don't forget that watches are just a mechanical simulation of a sundial.

How is arguing an empirical or theoretical point "off putting"? You say you don't know the paper well enough to criticize it, but I suggest you read the introduction. It is not technical at all and I'm not sure how you could come away from reading that fairly straightforward explanation of the paper's intention still thinking that it is "off putting".

The overall message of Piketty's book is that capital's share of income will rise due to the difference between capital returns and growth. It may be true that capital accumulation is and will continue to be driving inequality, and is certainly valuable to know if so, but you can't accept the assumptions on which that argument is based blindly.

This paper is not nitpicking a small point, but arguing against the main message of the book.

>If we took every actuary working 9 to 5, and instead threw all of their tens of thousands of daily working hours at coding a program to do their job, how soon do you think we could automate an entire industry?

Not very soon? If that were possible, don't you think insurance companies would have long ago jumped at the chance to drastically reduce their labor costs?

>The moral of the story is we should automate jobs that people don't like doing.

As you say, you can see this happening today. This is already how the economy works. No company is going to pay workers if they can avoid it. So what's the problem?

Telemarketing may not be useful, but now the goalpost seems to have moved from "prove most jobs are actually useful" to "prove no jobs of questionable utility exist"

I'll admit I'm not familiar with healthcare in Europe, but surely there are people whose job it is to estimate the cost of providing healthcare and estimate the probability of certain health events occurring.

Why does that make sense?

Right, I think a good way to draw that line is to not include employees who work for more than just the one company. Foxconn manufactures products for more companies than just Apple.

The value you add to the company is not based on how many customers were gained from your completion of task X or similar metrics. If you decrease hosting costs by $15k per month and only get paid $5k per month but dozens of others would do the job for $3k, you aren't in a good position to ask for a raise.

Your value to the company is how much it would cost, in time, effort, and money, to find a replacement(s).

I found this video useful.

Just fyi, the word you're looking for is "tenured professors could keep up..."

If a subset of these inferences are shown to be wrong, wouldn't you want to make a conscious effort to stop making them? It would seem that becoming less biased in your evaluation of people would benefit both you and those you're evaluating.

I don't know whether you were implying this, but paying for "unlimited" services when you wouldn't otherwise spend the monthly (or annually, etc.) fee on that product isn't necessarily irrational. It may be that a person isn't willing to spend $5 a book on 2 books because a book is only worth, say, $1 to them. But given that returns diminish at a low rate, that person could be willing to buy, say, 20 books at $1 a piece. In that case, paying for an unlimited service that effectively lets them do so makes sense.

I don't understand the distinction between creators and publishers. When you create a video for youtube don't you publish it yourself?

Edit: After looking at other articles, I assume the pie chart refers to situations where a copyright claim has been filed for a video. In that case, it seems the filer is the "publisher" and the video uploader is the "creator"
