kszxgz··on Porsche Taycan [video]
My impression is that German car brands usually do not focus as much on 0-60 accelaration as much as Tesla does. Especially for a Porsche, it's more about handling than drag race performance.

kszxgz··on Blood sugar patterns to master as a type 2 diabetic
Glycemic Load = GI * carbohydrates (g) ÷ 100. Accordingly, the GL in the example would only decrease if fat replaced some of the sugar. GL does not consider the totality of food intake but can be calculated for individual foods. (https://www.gisymbol.com/what-about-glycemic-load/)

What you are referring to may be the glycemic response, which, apart from GL, also depends on the intake of fat and protein among other things. Adding fat and protein does indeed reduce the glycemic response:

"It is generally accepted that adding fat and protein to carbohydrate reduces glycemic responses by delaying gastric emptying and stimulating insulin secretion (1,2). These effects have a number of possible implications for human nutrition, such as supporting the role of high protein or high fat diets in the management of diabetes (3,4) or being a source of criticism for the application of the glycemic index to mixed meals (1,5)." https://academic.oup.com/jn/article/136/10/2506/4746688

kszxgz··on Aphantasia: 'My mind's eye is blind'
So which characteristics do you describe when you're asked to describe a person? Which features do you imagine? The shape of their head?

I would assume that most people have some form of non-visual, database-like memory for each person.

(I sometimes lose the ability to recognize people when they change their haircut, when they wear a different type of clothes, or when they meet me in an unfamiliar setting.)

kszxgz··on Aphantasia: 'My mind's eye is blind'
While I previously thought I might have aphantasia, I now tend to think that most people lack the ability to imagine face or other complex objects. HN threads tend to confirm this.

In other words, while I can't imagine my family members' faces, I also don't think many people can.

If not proven otherwise, I now assume that most people forget the visual memory of faces after a few seconds while preserving the ability to recognize people.

Obviously this excludes people with photographic memory.

kszxgz··on Canada's New Food Guide
For comparison: Harvard Healthy Eating Plate https://www.hsph.harvard.edu/nutritionsource/healthy-eating-...

At least among the Harvard faculty, there appears to be a consensus that healthy fats are important, which the Canadian guide doesn't seem to stress that much.

Comments on the Harvard Healthy Eating Plate (https://www.pbs.org/wgbh/pages/frontline/shows/diet/intervie...):

INTERVIEWER: Some nutritionists have criticized your pyramid as "floating on a lake of olive oil."

WILLETT: The formal studies that had compared a more moderate fat intake as we've suggested, with low-fat diets, have actually consistently shown that people did as well or better controlling their weight on a moderate-fat diet compared to a high-carbohydrate, low-fat diet.

INTERVIEWER: Even good fats are more fattening than good carbs. So they think you're contributing to the obesity epidemic, or there's a risk of that. A tablespoon of olive oil is 14 grams of fat.

WILLETT: There are all kinds of beliefs about the amount of fat in a diet, tremendously strong opinions. What we really need is sound data, and the studies that have been done show that people actually end up controlling their weight at least as well, and usually better, on moderate-fat diets compared to low-fat, high-carbohydrate diets.

INTERVIEWER: Is it okay to get more than 30 percent of your calories from fat?

WILLETT: The evidence is quite clear that it's perfectly fine to get more than 30 percent of your calories from fat, and probably, in fact, it's even better to be getting more than 30 percent of calories from fat, if it's the healthy form of fat. ...

kszxgz··on The blind mind: No sensory visual imagery in aphantasia
That's my own experience as well. I would guess that this is how most people experience 'imagination'.

Same with faces: I guess nobody can really 'see' a face in their imagination, at least not for more than a few seconds of high-resolution short-term memory. They can, however, use their knowledge about nose shapes etc. to construct a symbolic model of the face in their mind.

kszxgz··on Apple self-driving car in accident: California DMV filing
If Apple doesn't expect to achieve a satisfactory return on investment they shouldn't enter a new business area, regardless of their liquid assets ('money reserves').

If expected ROI is too low they should return the money to investors (share buyback or dividends) and let investors choose a different investment with better prospects by themselves.

> By the way - 10% in 3 years would be a perfect milestone to 100% in 30 years.

That would be a reduction to about 35% of the original after 30 years.

kszxgz··on McDonald's Says Goodbye Cashiers, Hello Kiosks
Why do they not replace the kiosks with QR codes on the dining tables? You scan the code and order directly from your smartphone.

That's the experience I know from China. Are there any restaurants in the US that do it similarly? Or perhaps not due to the lack of WeChat and suitable payment providers?

kszxgz··on The brain may clean out Alzheimer’s plaques during sleep
"According to the new book Why We Sleep, by Matthew Walker, the director of the Sleep and Neuroimaging Lab at the University of California, Berkeley, the sleep people get on sleeping pills like Ambien is not true sleep. Drugs like these simply “switch off the top of your cortex, the top of your brain,” he explained to New York Magazine, “and put you into a state of unconsciousness.” That’s not sleep; that’s cryogenics. According to Walker, sleeping-pill sleep doesn’t have the same restorative powers—and there are lots, from an immune boost to emotional resilience—as good, old-fashioned zzzzs."

kszxgz··on Ask HN: What has the past 12 months taught you?
(1.) Peace through humility.

* The humble live in continuous peace, while in the hearts of the proud are envy and frequent anger.

(2.) Establish constructive, rational ways of thinking.

* Constructive thinking is defined as "the degree to which a person's automatic thinking ... facilitates solving problems in everyday life at a minimum cost in stress."

* The more constructively you think, the happier you feel, and the better your emotional adjustment.

(3.) Strive for joy and contentment, not happiness.

* It’s important to make a distinction between joy and happiness. Happiness is circumstantial, like the pleasure that comes from eating ice cream on a sunny day at the beach. Such happiness is slippery and can vanish in a second. But joy is different. At the very least, it isn’t based on circumstances, which means it can’t be taken away

(4.) Enable contentment.

* “Though a good dinner is not to be despised — yet it is not worthy to be compared with a contented mind, which is a continual feast.”

* Contentment may be particularly useful for counteracting problems that stem from fear and anxiety.

(5.) Be patient.

* That’s what patience is. It’s being able to have this sense, in the middle of craziness, that all is not necessarily well according to circumstances, but all is well. Patience is being rooted in something outside of yourself, even when our hearts are weak and frail.

* Listen patiently and with an open mind.

(6.) Reduce negative emotions.

* Distorted evaluation of our performance in front of other people is the reason for depression and anxiety.

* Most negative emotions are completely useless. Resentment, bitterness, hate, and jealousy have never improved the quality of life for a single human being.

(7.) Purity and simplicity give freedom.

* “Purity and simplicity are the two wings with which man soars above the earth and all temporary nature.”

* The happiest homes in the world are not those in which are the finest carpets, the costliest pictures, the most luxurious furniture — but those in which glad, peaceful hearts dwell.

(8.) Build beautiful habits.

* Most of the choices we make each day may feel like the products of well-considered decision making, but they’re not. They’re habits.

* Create healthful, beautiful habits to live sustainably and achieve long-term goals.

(9.) Exercise regularly.

* Regular cardio exercise can help you sleep better, feel more alert and energetic, and enjoy reduced risks for cancer, diabetes and osteoporosis.

(10.) Eat healthily.

* The key public health challenge today is to reduce intake of all highly processed carbohydrates in favor of whole carbohydrates (fruits, vegetables, legumes and minimally processed grains) and healthful fats (like nuts, avocado and olive oil).

kszxgz··on After 10 Years, Nathan Myhrvold's $3B of Private Equity Funds Show Big Losses
"Hate when companies not doing well try to dodge by blasting 'traditional accounting rules' when these rules have been crafted over the years to accurately reflect the value of said company."

I agree that criticism of traditional accounting methods often points to inherent risks and even corruption, see Enron.

However, as I understand it, measuring firm value is not the primary goal of accounting. The way depreciation is calculated, for instance, may be convenient for other reasons, but it doesn't say much about real values at all. Accounting numbers are quite artificial.

When analysts calculate firm values, through methods like DCF, they use accounting numbers from the financial statements as their inputs to calculate cash flow etc., but that's just for lack of a better alternative. In fact the numbers don't make sense by themselves and many of the accounting rules just make the estimation of firm values more difficult.

kszxgz··on YouTube’s top creators are burning out
This sentiment seems to be strongly related to the 'paradox of hedonism'. In short: Pursuing happiness itself may not lead to happiness. Pursuit of something other (greater?) than happiness may in fact result in higher levels of happiness.

"Unfortunately for the hedonist, constant pleasure-seeking may not yield the most actual pleasure or happiness in the long run—or even in the short run, when consciously pursuing pleasure interferes with experiencing it."

https://en.wikipedia.org/wiki/Paradox_of_hedonism

John Stuart Mill: "Ask yourself whether you are happy, and you cease to be so."

Isn't face blindness the inability to recognize people? What about the case where you recognize people but you can picture no human face in your head?

Why do you think there's an implied causal relationship? In my eyes, this statement is an analogy between two separate observations. The author is probably aware that correlation does not imply causation.
kszxgz··on The Sound of Madness
"He cannot picture his mother's face."

How common is the ability to picture people's faces in their heads? Is it more close to 60%, 90% or 99% of the population? I'm asking because I also don't have that ability. I think I lose the ability to picture people's faces a couple of seconds after seeing them, while preserving the ability to recognize them if I have seen them often enough.

"He can't recall his life."

What type of recall are you referring to? May I assume that factual recall is still present while visual, auditory and emotional recall is inactive?
