What if the behavior you don’t want is reliance on the technology?

You could probably get something that looks very close by 3d printing forms and casting it in tinted concrete.

No one in Congress, no TSA administrators, no President, and no judge has ever consciously had the thought that airport security was beneficial to them because it enhances state authority.

The TSA exists because it

1. Made some people look good

2. Made some people money

3. Was thought necessary by some true believers

The incentive structures aren’t aligned in a way that any individual cares about reinforcing state power like that. Mostly the people in charge care about getting reelected, keeping their jobs, making money, or in some cases doing good.

TSA lines suck because you have a bunch of hourly workers directing a a crowd of clueless people through a multi step process.

I just got back from Disney World with the family. We flew out of an airport with TSA, went through dozens of security lines at the parks, and flew out of an airport that doesn’t use TSA.

There was no meaningful difference interactions with any of the security personal. Some were nice some were annoyed, some were bordering on mean.

You clearly do have expectations if you are classifying people who don’t meet them as assholes.

People aren’t assholes just because they don’t accommodate your every preference.

> Why is it unreasonable to say, "I'd prefer something other than USian"?

Because all I’ve done is to fix my minor annoyance by making it the speaker’s minor annoyance.

And many people don’t like the term American, so now the speaker has to decide whether to please me or other people in the group, or come up with some ridiculous compromise like Citizen of the United States.

A big part of being an adult is dealing with minor annoyances.

Maybe you shouldn’t sort people into allies and assholes based on whether they are willing to change decades of language use to accommodate something that doesn’t even offend you (or as you say anyone else).

I try my best not to offend anyone at work, but policing my language to match the preferences of everyone around me would be exhausting. I grew up speaking a non-prestige dialect. I have a lifetime of experience policing my words. It can be exhausting. It’s easy to underestimate the mental cost if you speak a prestige dialect.

I spent a few decades being made fun of for saying y’all. I now find it a bit weird people who would have made fun of me for using it 20 years ago now use it themselves. I’m not offended by it, but my preference would be that non-southerners don’t use it.

However, I realize that it would be a bit much to ask that of everyone I interact with. And if I did it would be insane to label people who didn’t comply assholes.

I prefer that people that people don’t use learnings instead of lessons. I prefer not to be referred to as a USian. But I don’t expect people to follow my preferences.

My wife wasn’t sad because he was no longer getting free books.

My 5 year old just got his last imagination library book. It showed up right after Dolly passed away.

There was a letter from Dolly to him that ended “I will always love you”. Made my wife tear up.

> It did control for SAT scores through, so the one thing this study is definitely not doing is examining the effectiveness of public vs private schools at effectively educating children

Run that statement through AI and ask it if it says that private education can’t impact SAT score.

> Look, I’m not going to rebut each of your points one by one. Ask AI

Why are you even here? I think you’d be happier just going back and forth with AI all day.

Look at this guy over here with his math and his statistical literacy you guys. He doesn’t even spend all day talking to AI.

They don’t have to produce an optimizing compiler to claim a win though.

The study you’re referencing didn’t examine elite schools just non-religious.

And if you’re only counting elite schools there are so many uncontrolled confounders that this is a patently stupid argument.

Elite schools are selective, a large part of what they are selecting for is kids who are likely to get into elite colleges to keep their success rates up.

Of course kids who are screened for being likely to get into an elite college are more likely to get into an elite college.

The only realistic way to control for this is to look at kids who got into elite schools but decided not to go.

>check with AI

Kick rocks. I’m not normalizing this shit. Why didn’t you check with AI. It would have told you that omitting key information to save a few keystrokes was a bad move.

It didn’t control for wealth though just income. It also didn’t control for parental education or familiarity with elite colleges. It didn’t control for parental expectations (seems likely that a parent who spends money on private school will be more likely to expect their child to attend an elite college).

It didn’t control for the value parents put on education in general.

It didn’t control for children’s expectations (seems likely that a high school student who wants to attend an elite college will be more likely to push to attend private school).

It didn’t control for extracurricular activities (it seems likely that private school parents will be more likely to encourage their kids to participate in extracurriculars that look good on an elite college application).

It did control for SAT scores through, so the one thing this study is definitely not doing is examining the effectiveness of public vs private schools at effectively educating children.

>P(C | private elementary) = 5P(C | affluent public schools) = 35 P(C)

That can’t be true. A group’s probability cannot exceed the overall probability by more than the reciprocal of its population share. A 35× ratio therefore requires the group to represent at most 2.86% of the relevant population. For comparison, NCES reported that 9.3% of students in grades 1–5 attended private schools in 2016.

SQLite at its core is a compiler, and a higher level one than C, so I don’t think that’s likely.

Have they released this publicly? This seems about on the same order of difficulty to anthropic’s C compiler project, which ultimately failed. I’m surprised if they can do SQLite they wouldn’t show up Anthropic with a real working C compiler.
