The main thing that frustrated me about the SAT, at least when I took it, was that it essentially boiled down to an IQ test, not a true "scholastic aptitude" test. I did barely any prep (aside from, I think, a flip calendar with questions), but I scored 1510 out of 1600 at the time which qualified me for a prestigious program in my university.

Then I narrowly avoided flunking out because I'd never actually learned to study or manage my time properly in high school because I'd never needed to until college. Study skills and time management seem like pretty important factors in a true measure of scholastic aptitude.
I mean it depends, you could 3D print a lower receiver and fill in the rest with regular stock gun parts. The lower receiver basically holds ammo, and the trigger. In the case of a Glock for example it's the metal slide that does most of the work of actually shooting, the polymer frame is just there to hold everything in place.

This is why some guy was able to 3D print part of a Glock.

It's an antibiotic. Severe patients will be dealing with secondary (bacterial) infections, so it makes sense to use both. But on its own, I expect it would have little effect.
The dependencies is the trick.

Given I have this layout:

bin/bin.pro # specify bin/bar/ as subfolder
bin/bar/bar.c
bin/bar/bah.h
bin/bar/bar.pro
lib/lib.pro # specify lib/foo/ as subfolder
lib/foo/foo.c
lib/foo/foo.h
lib/foo/foo.pro
project.pro # specify bin/ and lib/ as subfolders

And I have a fresh checkout, how do I compile "bin/bar" and all of its dependencies automatically? I want to run ONLY "bin/bar". I don't want to compile the entire repo. I don't want to have to investigate "bin/bar" and learn all of its transitive dependencies. I just want to run "bin/bar".

Honest to god, I have wanted this for over a year and it does not seem possible.
These lessons seem very logically sound to me.

I wonder, if we were to think of (realize) human minds as nodes of a supercomputer, connected via wires and human "biology" (data to screen to eyeballs to cpu (brain), cpu to fingers to keyboard to central controller), and designed a system to optimize away the obvious efficiencies, what could mankind be capable of?

If we could wire in all the nodes from HN, SSC, LW, IDW, [insert communities/professions of your choice], and then pointed this "thing" at the problems we have on this planet, what might be the result?

But first, I wonder if you have to believe it's possible, if that makes any sense. I have a strange feeling that might be the hardest part.

EDIT: assume this is workable. What should be the first two problems to address?
Prisma provides a really solid approach for a GraphQL project. https://www.prisma.io/features/graphql-api/ . Graphile(https://www.graphile.org/) is another really nice library for a more advanced approach. IMO the big pay-off of a GraphQL service is the clarity of how the frontend describes data dependencies. To capture that full benefit, you've gotta go with Relay. Facebook designed Relay and GraphQL in tandem to work nicely together. Apollo and Redux are mediocre, but people argue they have a "more approachable learning curve".
>But this is exactly what SAT is intended to measure, scholastic potential.

But if you define the variable like this, you end up opening a can of worms.

Do rich kids have more scholastic potential because they have better access to resources? Or should scholastic potential be the measurement of how a child performs assuming they had the same access to resources? Should children who belong to a racial/ethnic group that have social stereotypes of having more scholastic potential be defined as having more scholastic potential because of the effect of stereotypes and labels, or should the measure of scholastic potential be of the underlying potential if the effects of stereotypes and labels were equal?

Normally measurements of potential aim to be to measure the factors least impacted by other factors, because if we account for those factors we are measuring actual instead of potential.
Companies typically make up their creation stores after the fact because a nice crisp story gives people something to hang onto.

If I understand, xiphias2 is agreeing with you - that Gmail went "behind" the abstractions, and was the better for it. That is, when you pushed the abstractions as far as GMail needed to, the abstractions leaked.
Those tiny square alcohol prep pads (e.g. for diabetics and others who need daily injections) are sold out everywhere. I suspect people who couldn't find hand sanitizer or Clorox just grabbed whatever sanitizing products they could.
These advantages are more subtle than even that.

I was shamed by some older fellow alums when I told people that my parents had hired someone to go over my application and essays. Their stance was that my parents gave me an unfair advantage (note, both of my parents are immigrants who did not even finish high school). My retort to them was point out that most of them didn't exactly grow up in the crime ridden rural parts of the world (quite the opposite in fact). Their parents paid a higher tax rate to support the world class public education they got, which they just assumed is the norm. That shut them up rather quickly.

SAT prep classes or not, coming from a more advantageous social-economic background grants you so many benefits in many ways. My parents wouldn't have to hire someone to review my applications if my school had a good college counselor (50% of my classmates do not go on to college).

She did not suggest anything about the intention. Only that wide-open testing would yield many more positives than tightly controlled testing. And if they're going to tighten testing that will reduce growth in positive cases.

The numbers you see on dashboards have A LOT of lag from the moment of infection. There's incubation. There's "nah, this is just a regular cold". There's calling the doctor. There's looking for a test kit. There's processing the test. There's reporting. Then the numbers show up on the dash.

Plus, there will be a lag between the moment the order is issued and the moment you see material changes in patterns of social interaction.

It's definitely not 1 week, and even 2 seems a little sunny side up.
Probably the only time it's appropriate for outrage culture and to focus on the negative is exactly right now.

Honestly, if I was black, I would just lay down with my hands behind my back anytime I was asked to be searched and never consent. It's certainly a rights violation, but I'd rather fight an illegal search/seizure case than a resisting arrest case. If they want to arrest you, they will, and I'd rather make that as easy as possible.

However, since I'm white and relatively well off, I'll try my chances with talking my way out of the search.
"And last, but certainly not least: I know we are making this announcement during the COVID-19 pandemic. We had already been planning to make this change, and decided to announce as soon as possible in part because we wanted to make sure no one was spending more time or energy studying for tests they wouldn’t have to take for us, especially during a public health emergency. "

Riiiiiiiight. 'Cuz nobody that applies to MIT ever applies to a back-up school. You know, just in case they don't get accepted. I've heard that can happen.

And that something may turn out to be noise.
There is another implication as a consequence of the statement "the influence of test prep, cramming, test coaches, etc. is minimal for the subject tests." That is, I first read thag the students don't suffer under these conditions. It is a valuable trait no doubt, to be able to cram swaths of loosely associated facts. I'd argue that it's a vital trade for study, but perhaps it is less severe than only twenty years ago, because very powerful memory aids have become ubiquitious.

> predict performance about equally well

having no tires or no engine predicts performance of a car--or rather the lack thereof--equally well. Yet grip and horsepower are independent variables. I think that means SAT scores don't predict success too well at all beyond a certain threshold.

Having the right motivation (haha, a pun) for a certain disciplin might make a huge difference. So you can test e.g. vocabulary learning in general, or top9cal knowledge, which requires precise choices of vocabulary nonetheless, but one not found in a general dictionary. It's more like knowing which dictionaries exist, and what texts are referenced therein.
Couldn't cities just limit the number of people in the park, and presumably couples live together or are in contact anyway?
100 points isn't that much. The average score is 1000-1100. The elite universities expect 1500. Tutoring, even if it gave you 100 points, isn't going to cross that gap.

I'd say it's still relatively fair. Fairer than essentially any other admissions criterion: grades aren't comparable across schools, extra-curriculars are much more about money spent, etc.
Quinine is amazing stuff and quite easy to make, but the poison is in the dosage. Controlling that when you're making your own with cinchona bark isn't something you want to do trial and error style, serious side effects.

> Who cares what the conventional wisdom says? The psychometric results are that SAT I scores and SAT II scores predict performance about equally well in isolation and don't have more predictive value in combination than they do in isolation. In other words, they measure exactly the same thing.

This is point where you take a step back and conclude that if this is your measured result, you may have been measuring nothing at all.

There is a long discussion about this study with the virologist Christian Drosten on a German podcast (transcript here: https://www.ndr.de/nachrichten/info/coronaskript134.pdf), though in german only.

He was quite skeptical about the study, in particular as it doesn't have randomized groups, and e.g. the age difference between control and treatment group was very large. He also didn't consider the virus concentration in the throat to be a good endpoint to measure as from their experiments they know that it goes down over time anyway, and the virus tends to move to the lungs.

eBay is a fascinating story for their early impact to the commercial internet. It is also fascinating to see how they've fared: it is still around but now it is being eaten up by competitors like Facebook Marketplace in the US, MercadoLibre in Latin America and others.

PayPal is on a somewhat similar trajectory.

The lesson here is to keep your customers happy or someone else will.

Also found it interesting to read about the people and companies who thought eBay wouldn't work for various - good - reasons. You can always make something work!

I don't think authoritarian tactics like that, while effective, would fly in the US. I for one would not be ok with that. Once the government takes that authority once, who knows what they end up doing with it when they see they can get away with it.

The federal government is in charge of managing interstate commerce under the Commerce Clause of the Constitution, so legally CA probably doesn't have the right to close its borders (this was used in Katzenbach v McClung as legal justification for the federal government banning seperate whites and colored sections in restaurants https://en.wikipedia.org/wiki/Katzenbach_v._McClung). Additionally some of the border traffic is for critical items such as food, medical supplies, gas, etc.
This is interesting, but I would have thought that gigabit ethernet would have higher latency than 100 megabit, because with spread-spectrum communication, latency tends to go up as bandwidth goes up. So ethernet must use a more discrete encoding.

I started looking up info related to this, but I'd be curious to hear opinions first. I'm having trouble finding what the potential bandwidth for ethernet would be if it went to spread-spectrum, and how much that might increase latency.
No.

It barely helps is a simple fact. Look at most of the masks being worn. The have huge gaps all around them. They do no cover the eyes. And if you're not used to wearing a mask you'll be adjusting it constantly -- touching your face.

What untrained people are doing is tying a fomite to their face and expecting it to magically protect them, ignoring the fact that most transmission is via your hands.
Look, I don't disagree with you -- other than the score SAT prep is fantastically bad education investment. But I think this is a problem with the testing more than some larger class issue. We've rewarded learning a bunch of useless facts and test taking strategies. You could probably switch out the SAT for an entire test of movie trivia and you'd probably get the same distribution of performance since ACT/SAT just reward the people who study for it the most. You can't accidentally prepare for these tests by other schooling that's not geared for it.

I personally struggled alot in college with the academic stuff. It got so bad that I was kicked out of the engineering department and ended up signing up for a degree in economics. After having gone through 2 years of engineering courses, the econ curriculum seemed like a piece of cake. However, I had a feeling that that would not be enough to land a job post-college (my GPA was also very poor).

Instead, I dove head first into trying to work with other people to build products that people would use. While none of those products ended up going anywhere in terms of financial success, the experience itself really helped me in articulating what sort of value I could provide to a prospective employer. In fact, I would give all credit in getting my first job to the fact that I was able to talk about the challenges I experienced with an on-campus recruiter who signed me up for an interview on the spot.

I really think the learning you gain by doing, building, etc really helps you grok the underlying academic principle. For me, I found that I have to do first and then go back and read up to learn what I've experienced.
That's science though. You have to just try and learn as much as you can, from as many different directions as possible, because we have no idea which approach will lead to useful discoveries until it does.

I bought aquarium chloroquine to use as a last-ditch resort if I basically have to choose between taking it or dying due to hospital overcapacity. No harm to patients there IMO. I spent $60 for the 10 grams recommended for a course (.5 g a day). That was last week, and it's so much more expensive now.
comparing apples to seed pods
Makes sense; doesn't everybody pretty much get perfect scores on these? (at least everyone who is a serious applicant to an institution like MIT) If everyone gets the same (perfect) score then the test doesn't really help the admissions committee select for the best applicants. Tests like AMC 12 may be more useful for this type of purpose.

Modern addiction specialists don't fetishize physical addiction the way many lay people do.

Today's announcement is, as the HN title says, an extension of the filing deadline to match the already-extended payment deadline.

I agree, as alarming as it sounds I think we'd need something much higher than a 2% fatality rate to justify completely giving up our civil liberties.

If anything it should be the elderly and vulnerable that are forced to isolate while the rest of society slows down for awhile, but even that I think is too egregious at this point.
Last time their argument was: "Currently, there have not been any COVID-19 cases in Pennsylvania".
Seconding this. We're 30 miles north of Seattle and there are tons of people still out and about. Beautiful weather isn't helping.
I really hope this virus prompts our disaster management agencies to get their shit together, and specifically to consider supply chain security as part of their threat model (and no, we don't meaningfully do this or we wouldn't have such a pitiful national reserve of respirators and other respiratory treatment devices following SARS and MURS). Not sure exactly what this would look like, but identifying key partners in industry and working with them to enable them to turn-key ramp up production seems obvious.
The problem we are going to have in the US is some states are responding better than others. NY looks bad right now because they are testing a lot. States like Florida, Louisiana and Georgia are already in double digit deaths each and don't have the positive cases to account for them. Going forward the rate of deaths will be far more indicative of what's happening than just the positive cases and that is going to continue to climb for at least 4 more weeks. Will we see a ban on interstate travel? What happens when one state gets the outbreak under control while another state's cases are still increasing? I'm extremely doubtful that any one state in the US will see a significant slowdown in cases in the next 4 weeks. No European country has yet...
Yeah that's the dream for me as well. I want the freedom to choose what I build. I don't ever want to stop building. I don't much care for most of what I build to pay the bills.
Ultimately, even if 60% of people are massively harmed or inconvenienced by the restrictions it is a life-and-death matter for healthcare workers. Viral load is a problem, and keeping down the infections will reduce patient interactions without adequate PPE and mistakes. It is indicative of a collective societal favor that we're asking nurses, PAs, and doctors to risk there lives for a preventable situation. The risk of a systemic failure to the healthcare system would be a catastrophe.
No, it won't. If people mingle and fail to "flatten the curve", the whole mess will be over sooner, albeit with more dead old people. If you believe you can starve the virus of hosts, you're delusional.

That's not relevant to the United States if we eradicate domestically and close borders. That said, Africa managed to contain the Ebola epidemic. Let's not underestimate their resolve.
