How is it designed and by whom?

I got a rapid test after getting the first vaccine -- I was told that there were more than one type of antibodies, the vaccine only provides one, so they can test for the others to see if you had the virus proper.

This is a known process already https://en.wikipedia.org/wiki/Vavilovian_mimicry

Examples of this are Rye and Oats.

Does that have any effect on reducing suicide rates?

College admissions are similarly a blend of different criteria: race, high school grades, did one of your parents go to that school (legacy), did your family donate to the school, are you a good athlete, are you a good musician, and of course what is your ACT or SAT score.

The exact weightings are not known to the students applying, but it's safe to say you can't just minmax on the standardized test.

I don't know if you've picked up the tone of some of the other comments in this thread, but people feel very strongly about what factors should be considered in college admissions. Almost no people will defend legacy admissions, few will defend athletic admissions, some will defend musicians, many will defend GPA and standardized testing.

College admissions are zero sum, and different weightings benefit one group over another. For example, "Asians" (the US does not differentiate South Asian [India, etc] from East Asians [China, Korea, Japan]) have very high test scores in the US. If you base your college admissions just on taking the people with the highest test scores, you would get a massive over-representation of Asians. Schools have decided that isn't what they want, so they take people with worse test scores in order to "balance" the student population.

This infuriates the people passed over in the name of "balance", naturally.

The class grades are made up of some mix of:

* Graded homework

* Papers/Project/Labs

* Midterm/Final Exam

The teacher chooses the exact mix per class, so it's possible you fail even if you ace the exams, or pass even if you fail the exams. This variability is why the standardized tests exist.

The purpose of standardized testing is the standardized part.

It's a convenient way to compare students from different schools. The per school graduation exams have the benefit of allowing customization on a per school (per class, even) basis. This customization is one of the good things about the US education system, IMO. We are not like Germany, with the track set for the student (Gymnasium vs trade school) at middle school age, nor are we like India, China, and Japan (single extremely high stakes test).

US schooling is uneven. Some of the schools are very good (well funded private, religious schools with a focus on schooling instead of dogma, public schools in wealthy areas). Some are terrible (public schools in poor areas, public schools in cities).

Standardized testing, when viewed from one angle, makes the world more even: the test "doesn't care" (debated) what race you are, the wealth of your parents, etc. It "objectively" (debated) measures aptitude, giving equal opportunity to all.

I'm fairly sympathetic to that view, and I'm also skeptical that removing the standardized testing requirements will lead to more equality. Standardized testing seems like the method least susceptible to rigging by rich parents, what will they replace it with that is fairer?

Making laws that target personal liberties in the hopes that they will be selectively applied does not increase justice.

Thank you for this, it’s a wonderful thing and I likely never would have found it without your link. My sister and I are planning a road trip, the only thing it needs is a theme. Surely we can find one in the guides.

Do unified backends mean that the government can't enforce antitrust action? That would be quite the loophole.

Insurance is a tax on everyone, and probably a tax on you specifically.

Even assuming that insurance companies act as naive rationalists believe they do, losses are socialized. In actual fact, insurance companies are able to price discriminate against policy holders likely to cost more than the average cost in the future, especially if likelihood of future losses are as public as court proceedings.

Short answer: reg fd requires companies to disclose information material to investors to all investors. The previous post is suggesting that the close work with the bank analysts is conveying material information without proper disclosure. My hunch is that the legions is compliance lawyers at both the banks and at the companies have deemed this to be within the bounds of the regulation, but we’ll see if the SEC/US Attorneys agree.

"Investemnt people" are reading research reports from banks (and their own analysts), not relying on mass market papers for the news. You can see it on Bloomberg.com sometimes, there will be a link to a story with more economic detail, but it will be gated by a terminal subscription.

Now you've shipped your thing that lasts forever. If it's a mechanical object, maybe you can get continuing revenue from spare parts, but those will bring in less than the original purchase. Worst case, someone brings up a factory copying your part design (without doing any engineering work on them, just copies them exactly), and undercuts you.

If you sell software, do you let the old stuff atrophy and become insecure? If not, you are spending salaries on maintenance without any associated revenue. As time goes on, the maintenance costs increase without bringing in another cent.

A cool thing I learned from watching AvE's channel is that bearing surfaces are meant to last forever if properly lubricated. The oil in them is meant to take all the load, and the metal surfaces should never touch. If you don't replace the oil regularly, or let it get so hot it flows out of the journal, the bearing will wear and need replacing. The design is meant to last a really long time if properly serviced and not overloaded though. (I'd love to hear from a MechE if I misunderstood, I'm just a dumb programmer who watches YouTube).

Are China's out-sized promises or environmental destruction more egregious than the same problems in the US or UK?

The air pollution currently in China is pretty bad, but air pollution goes away pretty quickly after you turn off the coal plants, and oversized promises to pensioners seems like a pretty easy obligation to amend when you have total control over the state.

In the US, you can have your kid run and play outside if you live in a suburb, in fact a better life for their children is what pushes many families to move to the suburbs in the first place.

Why are record companies still attractive to musicians today?

In the past, selling music meant having access to capital equipment (the vinyl presses), access to marketing budgets, and access to the record shop inventories.

Now, music can "pressed" for free by Spotify, Apple Music et all, shelf space is not limited (computer storage is cheap!), and the marketing can be done online more cheaply (I assume).

With all these stories of successful artists in the past (like Erroll Garner) and in the present (like Taylor Swift) being chained by their record companies, why do present day artists sign with a record label?

I'm sure I'm missing some key facet of the business, what is it?

Ulrich Drepper. I know him personally, and respect his contributions to glibc. His writing style on bug tickets was blunt, but in most of the examples I’ve seen I believe he had the correct argument in the end (the exception is his calling ARM a toy instruction set).

It was the second post by the time I got there, but the rankings are fluid so here's a permalink: https://photo.stackexchange.com/a/112702

I think it's just interesting to a lot of the HN audience. A modal HN reader stumbled across the post, they found it interesting, they thought it would be good to post on HN, and it was.

I think it's interesting to the modal HN viewer because although FFTs are pretty neat intrinsically, but most people are exposed to FFTs through sound processing (if they are exposed to Fourier Transforms at all, I don't think they were a required part of the CS curriculum at my university, they were only required for the EE courses), so the application of FFTs to images seems like total magic.

The explanation that jpegs use FFTs is ho-hum if you spend a bunch of time doing signal processing at your day job, but there are many intellectually curious developers who spend their day job gluing together CRUD apps.

That is not what is traditionally referred to as arbitrage. You are betting on an unknown variable (correct discount), not noticing pricing for the same asset being different in the same moment. Arbitrage is “sugar being sold at $2 at shop A, and bought at $3 at shop B, and the shops are next to one another”

I wonder if this is unconstitutional: some private schools are religious.

I think the parent is saying you /can/ use threads, but they will all contend on the GIL.

This is being told from a programmers point of view. Dave was cool from a programmers view. Writing code which enriches the ip owner is cool from the owners point of view.

Arguably defending the right to refuse to testify.

Wait, naked short selling is unrelated to insider trading.

Insider trading is illegally profiting on information that was given to you in trust, while naked short selling is short selling without a documented ability to deliver the stock.

As far as I can gather from english language articles, the regulator has banned short selling in response to an article alleging fraud at wirecard. Bloomberg describes this as "unprecedented".

To be very clear to all readers: front running is illegal. No one in the automated trading industry refers to the non-illegal trading that they do with a reference to illegal trading.
