By age 17, he published 10 peer-reviewed manuscripts in quantum field theory and particle physics. At 19 he got his PhD in particle physics from Caltech. Age 21, youngest ever recipient of what they used to call the MacArthur "genius" grant. Then struck it rich founding a mathematical software company. So, to be fair, he's done ok for himself.

The links that are included shed more light on things. The write-up linked is a little light on details, and I also expected an actual "flaw". What the other links show is a series of anecdotal reports that the k-series intel processors have been found by end-users to become unstable, and that setting more conservative power management settings in the BIOS helps these chips regain stability.

The argument is that Intel is selling chips that at their out-of-the-box recommended use patterns can wear out extra quickly, and by default are over-volted. So it's not a "flaw" so much as not having a great engineering safety margin for premature wear.

If you assume labor is 50% of the cost of a coffeeshop, and maybe only 30-40% of the cost when you factor out management, prices would have to go up only 6-7%.

And remember, you are assuming a zero-net-revenue change.

Maybe your former non-tipping customers would see that 6-7% increase and leave, but your former tipping customers (who may be price sensitive, but tipped because they believe in it) would see a decrease in pricing, from a 20% gratuity reduced to a 6-7% price overhead. And some of them would probably still tip anyway.

On the flip side, I remember reading a story of a parent listening to their child bark orders at Siri/Alexa, and thinking that even though there's no need for politeness, they felt that maybe they should teach their child to treat it kindly and politely for the sake of the child's emotional development in terms of empathy.

I can't browse twitter anymore with my iOS 3rd gen ipad. It was impossibly slow as recently as three years ago, and sometime in the last year they blocked my OS/browser version altogether with a "not supported" page.

This is a site that hosts 148-character text strings.

For the US, they've forgotten a few:

Archer-Daniels Midland, oils, feed, ethanol, corn syrup (rev $65 B)

Sysco, restaurant supply (rev $55B)

Tyson, chicken (rev $44B)

Cargill, like ADM, oils, feed, ag products (rev $113B)

I don't know a whole lot about this, but I seem to remember that there was one design decision, that, while not wrong, was different from the generation before, and that is that the airplane yokes were not mechanically coupled to one another. If they were mechanically coupled, the experienced pilot could have felt the other pilot pulling back on the controls, but what was happening was that the two pilots were pulling the controls in different directions AND the plane was averaging the control inputs and giving no feedback to the pilots that what each was doing was wildly inconsistent or contradictory.

My math was fine, but I did get the base numbers wrong. Should have been 120L as mentioned in the article, which equates to 88.577 m^3 at 15C, which is pretty chilly. 20C is more like room temp.

But, I'm not sure your math is quite on the money either.

This article isn't great.

First, it illustrates an MRI story with a (mislabeled) picture of a CT scanner.

Then, it overestimates the volume of gas expelled by a factor of 1000.

170L X 750 = 90k L = 90m^3.

This would fill a 35m^2 (about 350 sq ft) room, maybe the size of a living room, with pure helium.

I don't follow you at all. If the information available to the market is provided at the point the insider executes the "sell" then it is the B trader who provides his information later, and all the B traders will tend to act nearly at once.

In the A scenario, the A traders sell immediately, and act upon receipt of the inside information, rather than react to each other, so the information is furnished to the market gradually by all A traders.

Please tell me in more detail what you think of the scenario that I posed, and how it makes the point of the article.

Wow. I remember that back in the day, it was commonly argued that derivatives trading would reduce volatility in the markets. This is no different. Under certain assumptions, insider trading would lead to a more efficient market, and under others, a far less efficient market.

Quick question: which of these scenarios do you think captures the mentality of an inside trader?

A: I NEVER hold shares in companies that I do not fully believe in, and I ALWAYS take a long position. If I get inside information that a company is in trouble, I will immediately liquidate my position-- it may not blow up on me today, or tomorrow, or even this year, but I trust that sooner or later the stock price will take a dive, and I want to be long gone when that happens.

B: I have inside information that a company is in trouble. I don't know when it will blow up, but I do know that I have an edge on everybody else who doesn't know what I know. So, I should ride the stock all the way up, as long as it keeps going up, and short it on the first sign of trouble on the technical indicators. This way, I can make my money on both ends-- the up and the down.

One of these strategies will act to reduce volatility, and the other will enhance it.
