I understand the gist of this research: pulsars emit radio waves at regular frequencies, so by monitoring radio waves received from pulsars in the sphere surrounding us, we can measure correlated anomalies in their frequencies and infer that they were caused by large gravitational waves that effectively changed the shape of the transmission medium. That makes sense.

But this is not measuring the gravitational wave itself. It's measuring the change in trajectory of the radio signals that are "riding" the wave. In the ocean analogy, it would be as if we were surrounded by a circle of floating turrets that each emitted floating darts at regular intervals in all directions. Then we would measure the time it took the darts to reach us, and from that we could infer the size of the waves the darts encountered along the way. But we never actually see the waves, only the darts.

So my question is: how can we tell the difference between one really big wave, and many really small waves that would sum to the same effect? In other words, we know there is some waveform(s) that changed the velocity vector of the radio signal. But if there are multiple arrangements of waves that would produce the same change in signal, how do we pick the right arrangement?

Today, I don't think the tools are good enough to make a material difference. It may help a bad engineer tread water, but it won't take you from good to great. It may save you time writing basic boilerplate and individual functions, but I suspect 99% of engineers don't struggle with that. What's hard about our jobs is knowing how to orchestrate the whole thing and put structure around complexity. AI can't do that yet.

When I use it personally, it feels like a harder context switch trying to describe in english what I already know how to code. Then I still have to review the function to make sure it's accurate. It feels like a waste of time and an additional context switch.

Whenever the AI gets better, we'll have to use it to be productive I have no doubt. But the pool of engineers will change too - there will be a categories of engineers who can't debug the AI output and who still write crazy prompts.

Maybe I'm old, but I'll only be worried about AI when it can write and maintain a full app with no human intervention.

There's an implicit assumption that the risks are somehow reasonable, or at the very least, that the other party isn't being reckless or negligent.

If you ride a roller coaster after signing such a disclaimer, it's still reasonable to expect that people are tightening the damn bolts. And it's insane to expect both roller coasters to remain a viable business and individual riders to check that they are safe. At best, your attitude makes it nigh impossible to conduct business.

When I was growing up ('90s, 00s), that was the "movement" and teaching that was going on. It's colloquially known as being "colorblind". It has radically shifted the opposite direction. It's the difference between equality and equity, equality of opportunity vs. equality of outcome.

I don't know what's right or wrong really but I can say that the rapidness of the shift was definitely shocking to me. There's a lot of disagreement between Gen X, Millenials and Gen Z on the topic because of it.
Look at grade averages for med schools over time.

Also if the school is willing to bend their standards on admissions, who’s to say they won’t bend their standards on grading? It’s also almost impossible to get fired from a residency program once you get in, graduation rates are near 95%…

I already don’t trust MD’s compared to DO’s because MD schools nearly all got rid of grading and all classes are pass/fail which encourages doing just well enough to pass. DO schools meanwhile continue to grade students which encourages excellence.
And that system would pay for itself at the first event.

> Many universities have for too long wrongly concluded that the touchstone of an individual’s identity is not challenges bested, skills built, or lessons learned, but the color of their skin.

This conflates whether racial discrimination is legal, with how much people base their identity on race. Because on the latter question, the universities have concluded correctly - 74% of Blacks, 59% of Hispanics, and 56% of Asians (but only 15% of Whites) say their race is extremely or very important to their identity:

This is something that actually got Harvard in trouble as alumni interviews rated Asians roughly similar to Whites, but the personality scores that the admissions offices gave Asians were lower even though they never met the candidates.

"Alumni interviewers give Asian-Americans personal ratings comparable to those of whites. But the admissions office gives them the worst scores of any racial group, often without even meeting them, according to Professor Arcidiacono."

Getting into the weeds of defining who is and is not deserving of wealth redistribution is just going to waste society’s resources by pitting tribe versus tribe, and ironically mostly helps those at the top.

“Poor” is easier to define and rectify, and at the end of the day, I think the goal should be to provide a floor to members of society and maximize opportunities to all.

I had no impostor syndrome. Many of my peers didn't either; it's certainly not the case that almost everyone feels it. There seemed to be little correlation between ability and impostor syndrome too, so it's not a question of ability. But I digress.

Decades out, and understanding university admissions in-and-out:

1) At least an order of magnitude more people "belong" at MIT than there's space for. Elitist universities manufacture scarcity.

2) It's a pretty random process if you get in or not. The level of noise in admissions is huge.

3) It's not a meritocracy otherwise. There isn't a single axis of "quality," and if there were, it's not what admissions selects for. A lot of this became public with the Harvard lawsuit, where it turned out close to half of white students at Harvard got in through back doors (alumni, legacy, children of faculty, athletics, etc.). MIT is different, but no better.

4) Where you go matters a lot less than we make it out to. So much of MIT (and other elite schools) is about building out alumni as brand ambassadors. It's like the magic of Disney -- manufactured by PR departments to fool people. MIT builds itself on being hyper-elite, but there's no difference in quality of individuals at MIT, Georgia Tech, or many other good schools.

5) The elite school advantage is mostly in having a brand stamp and a power network when you graduate, not educational. That helps a lot of you're trying to be a CEO, faculty member, or similar, but not so much for the jobs 90% of my MIT-graduating peers are in. The educational outcomes are the same.

Unfortunately, the "best-and-brightest" brand-building leads to things like impostor syndrome. It may help if you know you were manipulated, but it probably won't. It's pretty deeply embedded in most graduates, and even if you know everything in this post internally, most people take decades to internalize it.

Breaking conditioning is hard.

It has a surprisingly strong effect as schools get more prestigious / exclusive. At schools like Harvard, which have in incredibly low admission rate (something like 5% of qualified applicants get an offer, I think?), legacies get a massive bump.

https://admissionsight.com/harvard-legacy-acceptance-rate/ says it's 25-35% of students who're legacies at Harvard.

https://www.nber.org/system/files/working_papers/w26316/w263... is analyzing the admissions data that got released from an earlier lawsuit against Harvard about Asian American admissions bias, and says that although being a legacy isn't as good as being a recruited athlete, it still gets you admitted at about 5x the rate of non-legacies.

NUL is a character. It's not there only to support C strings but rather predates C. In principle it's possible to have ASCII and Unicode strings with NULs in the middle.

Now, in practice and because of C, strings with NULs in the middle are a hazard -- a security hazard. And because of that one could forgive a SQL RDBMS doing as you say, but it would not meet the SQL standard.

The language has been "complete" for a long time. If you're actively trying to get something done, I think it's unlikely that some core language work is going to stop you.

It isn't clear what domain the parent wanted to work in; I won't say it's impossible they had problems but ... details are everything at this point.

The academic part of Racket gave rise to `syntax-parse`, a truely fabulous improvement over the standard Lisp/Scheme/whatever you used to work with way to write macros.
This doesn't seem to be the right tack. There's legitimate reasons to favor sellers that use your own logistics. Hard to see that as anti-competitive. Even harder to see why they picked this issue when there's seemingly many more blatant ones going on.

I believe what they don't realize is that many places use RHEL on critical systems, but Cent/Rocky/Alma on non critical systems, because they don't need support and can't afford it even if they did.

I showed of the HL2 experience many times and I was actually quite impressed how easy it was for them. HL2 instantly recognized a new person and I put out the training app along with others.

No books but some experience.
(1) don't try to push things, kids develop at different rates.

(2) eg we didn't potty train until she was just 3. We tried before that but it was stress with no upside. After three she had like maybe 5 'mistakes' over three weeks and that was pretty much it. You mileage may vary.

(3) When your new born is about two weeks start staring in their eyes and stick out your tongue. It takes a few days but in a while they'll stick out their tongue in response. From there the sky's the limit for tongue communication. Way more fun that you think. I did this on my own but there's an early childhood educator who recommends it too and wrote a book (can't recall the name)

(4) Discipline. Use the 'block system' it can eliminate almost all the time outs. For age 2y and 3y use five plastic blocks. Every time (use your judgement) they do something bad put a yellow plastic block in a visible but unreachable place. After they have five blocks up they get no more videos for the day. For age 4y and 5y do the same but use 3 blocks (at the younger age they eventually clue into 'oh, I have five blocks, I can burn three of them with no consequence').

(5) videos are not the tool of the devil. Kids naturally pay attention to the highest source of information that's available. In a boring house with slow changes (unlike, say, moving through the landscape all day long with a nomadic tribe) that information source is videos...but watch out for sunny bunnies no more than three day :)

(6) Between the ages of 2 and 10 kids are good for absolutely nothing except learning languages, at which they are certifiable geniuses. Try not to waste this valuable window in time.

If we neutralize generational economic disadvantage, we also eliminate any merit to the claim to compensation for economic injury to past generations.

I would rather no one bear the economic burden of the myriad of diverse injustices committed by our society in the past than that only specifically the descendants of those enslaved in the past be freed of the economic harm of that particular injustice, even if its effects could be fairly isolated, computed, and compensated.
Yeah I agree it might be tough psychologically. But from the deepest human point of view it is only fair. Why should you be the only person who bears the burden of the 100% result of someone else's actions?
Worms Use Electricity to Jump
All else equal, poor white kids probably get a leg up as well if they can articulate it in some way in their application.

For example, my (white) dad got into Yale and Princeton, and it probably helped that he was from a podunk town in Wyoming.

For a lot of poor white kids though, their situation isn’t obvious from their application.
Laziness? It’s cheap and it gives them a lever they wanted.
Sounds bad, but the WSJ summary makes it seem more reasonable:

It's sounds like total crap.

Yes, the risks are still there even with no safety violations. I bet it didn't say in the waiver forms that the viewport was only certified for 1300m and that they were going way lower than that.

I think it's worth considering how much economic mobility is tied to economic status prior to college. I find a purely race based admission system fails to identify that, and in place gives an easier solution to building diversity compared to giving discounted education to those who can not afford it.

Of course there remains issues of opportunity for students of color, who are more likely than white students from disadvantaged backgrounds. However economic status, or rural/urban based admissions would capture many of these inequalities.

Of course this all comes from a conversation that supposes college should be as scarce as it is, and that the earnings benefit from college should be as large as it is.

So you're saying the SAT gives a bigger advantage to people with resources to prepare, compared to a GPA which is the result of many assignments and tests across four years? That does not sound remotely plausible to me.

SAT + grades is a stronger predictor of college performance than grades alone. AFAIK this is a pretty uncontroversial finding. For a review article, see Frey (2019), "What We Know, Are Still Getting Wrong, and Have Yet to Learn about the Relationships among the SAT, Intelligence and Achievement."
