AS37··on Daniel Gross: Why Energy Is the Best Predictor of Talent
This is a promotional piece for a new book that comes out May 17th (https://www.amazon.com/gp/product/B08R2KNYVX)

One of the authors is known for being a YCombinator partner. The other is known for responding to every email. I'm not sure which is more impressive.

Bet sizing, maybe? It's certainly destroyed some big funds.

AS37··on How the ancient Romans managed their toilets
IIRC they eventually figured out to soak the sponges in soured wine (a.k.a. vinegar) as an antiseptic.

Which may add some depth to this passage:

> About three in the afternoon [while being crucified] Jesus cried out in a loud voice, “Eli, Eli,[c] lema sabachthani?” ... Immediately one of [those standing near] ran and got a sponge. He filled it with wine vinegar, put it on a staff, and offered it to Jesus to drink.

AS37··on Ask HN: Messed up my education, now 30 and regretting it. What to do?
Yeah, OP is basically the perfect candidate for WGU. With transfer credits and work knowledge they could probably get a bachelors in a year and go on to OMSCS.
AS37··on CBT Harmed Me: The Interview That the New York Times Erased
Joke aside, harm is well-defined and distinct from hurt. That "torture" will hurt, but should not harm.
AS37··on Ask HN: Is there any way that using pinch-to-zoom could change/add pixels?
A defense lawyer gave an example - if you have red pixels and blue pixels, would the added pixels between be purple, a color not present in the original image?

The answer is: bicubic, yes; bilinear: yes; nearest neighbor, no.

AS37··on Against Persuasion
> The intellectual left loves to pump out articles and books trying to explain right-wing thought: ... https://en.wikipedia.org/wiki/The_Righteous_Mind

> Every time liberals lose elections, there is hand-wringing about understanding the other side. But I've never seen the equivalent worry about how conservatives can understand liberals.

One of the big theories in The Righteous Mind can be used to explain this. The Moral Foundations Theory lists 5 drivers of moral judgments, 5 reasons why people may feel things are 'right'. Then it gives data showing that liberals feel 2 of these strongly and 3 weakly, while conservatives feel all 5 about as equally strongly.

By that theory, the reason that conservatives need not work as hard to understand liberals is that they feel all the same moral impulses liberals do, and more, while liberals only feel 2/5ths of the conservatives' impulses.

The same theory suggests that conservative persuasion will be more effective on liberals than liberal persuasion on conservatives. This then leads to election losses, which leads to hand wringing about how liberals don't understand conservatives, so they can't convince them to vote liberal.

AS37··on Show HN: I discovered a trading algorithm that returns ~24.85% annually
There are still parameters here.

On {day/week/month} n, determine which {n} product(s) of {product brand}'s {product type} of {underlying asset type} gave the {highest/lowest/some of each} return.

At n + {a number} {days/weeks/months} go {short/long/some of each} at {market price/limit price} at {market open/market close/time in day} the previously identified securities. Close your position on day n + {a number} afterward at {market price/limit price} at {market open/market close/time of day}.

Overfitting, even on a 20 year dataset.

> At the very least they are paid very very well... to state only the information consistent with what the person paying them wanted to them to say

Anecdotally, if you replace 'paid' with 'incentivized' my understanding is the same.

And here's a totally unrelated Wikipedia link: https://en.wikipedia.org/wiki/Michael_Baden

Interestingly there's an area of psychology called Naturalistic Decision Making which studies how experts make decisions that they can't explain. (Example: a firefighter may be able to pinpoint where a fire is before they enter a house and see it.)

I'd like to encourage you, 5 minutes after you learn about someone's existence, not to wish for their death, execution, imprisonment, and /or disenfranchisement. The real world is too complicated to judge correctly in that time.

> a forensic pathologist was giving fake prosecution evidence

The doctor handled thousands of cases in his career, and a well-funded inquiry found issues with less than 1% of them.

Sure we'd like that to be 0%, and society should spend time thinking of how much they rely on complicated processes of reasoning, but that's a really good accuracy.

There are private MRI businesses, but not many. When a friend of mine had some hard to diagnose brain malfunction his family drove to NY to get one.
AS37··on Ask HN: What is the best book you read in 2020?
Alchemy - Rory Sutherland. Written by an advertising executive, it's filled with little gems, especially about signaling.

Honorable mention to The Elements of Eloquence - Mark Forsyth, which is a delightfully light read about the patterns in English phrases, but I finished it 2 days before the start of 2020.
