This is an antibody test which will only be positive days after the onset of symptoms.

This isn't really what your Twitter link says. That links says: "Both IgM & IgG (those are two different kinds of antibodies, with IgA being a third) were low or undetectable at day 0, but increased by day 5 in nearly all patients (N=16)"

-- Reports strongly indicate there are many infected people who are asymptomatic after five days.

Which is to say, this test could be extremely useful if applied widely and systematically to many people; food service workers, health care workers and so-forth.

Currently the virus test has a week turn around time. So both tests effectively find people with a week's exposure.

One vendor provides an HTML5 “frame”. Sounds questionable.
If the hospital were full, as they are expected to be due to the steep curve of infected, there is a real chance you could have died. Are you saying that is fine? Should we not try to flatten the curve as much as reasonably possible?

Apart from that, it's not like there is no economic help. In Germany, for instance, there is a rather easy process for the employed as well as businesses to get state funding. So it is not like most businesses will go under or people lose their houses.
If the subject test was a thing that everyone was informed about, did not cost extra, and was readily available, if not required alongside standard SAT administration, then I would be more inclined to agree. But here knowing that they even exist is half the battle.
First Airbnb use, I booked a week just outside a national park. While driving, just before I arrived, the host cancelled, leaving me with an option of cancelling my trip, or a $400/night Best Western. Airbnb should have compensated me for that one. I’ll never use them.
Downloading updates for games has been a sore point with me, particularly when I get a new game. Oh great, 8 hours of downloads, so much for that instant gratification of playing it tonight...

What about rounding up all of the 'at risk' people and sending them to FEMA camps to prevent them from coming into contact w the virus? If most people infected with the virus are asymptomatic it seems like we're going at this the wrong way by universally working so hard to avoid it.
There are two sides to an exponential. If R0 is >1, it just keeps going up. However, if R0 is <1, it just keeps going down. The point of the lockdown is to get it <1 so it keeps going down for a while, until the case counts are low enough that we can adopt a different strategy.
As an INTJ, I have been suprised about accuracy of the test + results.

I'm curious about what other people think about it.
The total number of confirmed deaths (~250 in the US) is still incredibly low compared to the normal number of deaths attributed to respiratory problems over the same time range. Anecdotally, I keep hearing from other healthcare professionals about the high number of respiratory-related deaths in hospitals lately - most of which never get tested for Covid. I'd really like to know if there has been a bump in respiratory deaths since January that exceeds the number of Covid cases.

Maybe Airbnb lost in the short term, but maybe it pays off in the long run. I had to cancel bookings both on Airbnb and on Hotels.com (which I used to be a gold member; now silver), and the experience on Airbnb was perfect. Meanwhile, I lost some money and time calling Hotels.com (two hours in total).

I'll definitely consider Airbnb more often from now on after this great costumer experience.
Maybe this is will be seen as radical but I think the best way to end all this gaming is for collegeboard to not release their previous tests to the public. There simply shouldn't be enough data out there to study the test rather than the material. All that should be known in advance is the topics, format (multi choice v. Open ended) and point system. I'm sure the cottage industry of test prep companies would hate it, as would those that prefer studying the test to having merits, but those groups can pound sand.
Not so great if people are using to test to see if they're "immune"
If you're going down that route I recommend Qutebrowser[0].

I'm a pretty staunch advocate of it since it doesn't feel at all like a "hack" of vim in the browser, and because it's chromium basically all websites work. (However, I am contributing to the monopoly of chrome based browsers, which is a bad thing in my personal opinion).

It's also easy to extend, I think it's the ultimate hacking browser.

PS: it takes a little tinkering to get really nice looking on MacOS.

Bingo. The only instance where I prefer phone calls over text-based communication methods is when I just want to talk about nothing with family members who live far away and who I haven't talked to in a long time, just so I could hear their voice. For anything functional, I prefer text-based methods all the way for a multitude of reasons. Having full logs of the conversation to reference later on is a huge boon when it comes to avoiding misunderstandings and getting things done.
I miss the 90's. Too bad the thing that ultimately made the Internet sustainable also ruined it: the masses.
Maybe, but foldr (:) [] ~ id is an illuminating fact in its own right that is worth pausing to understand.
So if I got that right, the future best practice will be to use foldMap/foldMap' on all data structures unless you require a particular associativity.
The refunds usually come within a couple days of submitting, if it's electronic. Longer if it's paper. State is usually within a week or two for my state, but may be different for yours.
Good test takers are people who have learned things and know them well enough to pass a test on it. There are many kinds of test. The SAT is the kind designed by psychometricians, experts with Ph.D.s building on millions of man hours of research to make tests that are both valid and reliable, that predict success in college and are as close to ungameable as possible.

MIT could drop the real SAT tomorrow and still fill its freshman class with valedictorians who captained their high school sports team and have ten AP 5s. Schools with fewer applicants have the SAT.

> argument that starts "What conservatives are proposing is to privatize the upside of the economy while socializing the downside."?

The thing is, that's not an argument at all. At best, it's demagoguery hiding behind weasel words. The role of the state is to compensate the lack of economic incentives to provide the public with some goods and services in order to ensure that the people has adequate access to them.

The key factor is, obviously, that the role of the state is to bridge the economic gap. Not to profit from a service, but to ensure that a service is provided in spite of not being profitable.

And it is this way by design, isn't it? After all, who in their right mind would argue that the state should turn a profit on selling goods and services back to its own tax payers?

That's a very... naive view of how a GPU works. Particle simulation is done in compute, and ray tracing, as implemented in RTX/DXR, is done on a soup of triangles. The core of rasterization is still done on triangles, and can't easily be done in compute. Have any references to parametric curves on GPUs? All the approaches I know of, like the recent mesh shader work, still output triangle meshes.

I was hearing some doctors saying on the radio that any flu immunity is short lived, this is why we need to have the anti-flu vaccinations every year, that cover the typical/usual strains. If immunization lasted forever there wouldn't be a need for annual vaccination.
On the contrary, we're learning that our economies are incredibly resilient. Nobody's concerned that we'll stop being able to deliver food, water, toilet paper, Netflix - the businesses which provide those basic necessities (and imagine telling someone even 30 years ago that on-demand home video is a basic necessity!) are almost entirely unaffected. This is a success story of capitalism by any reasonable metric - I would not have predicted that Amazon could keep making deliveries and Costco could continually restock their shelves in the middle of a global pandemic.

Unfortunately, even the best economic system can't disguise the fact that fewer people working means fewer products and services are available.
But this is an antibody test, for people who have already recovered from the virus. False positives in this case are precisely what would give people a false sense of security.
Yeah, it just continues a general pattern I've seen between MySQL and Postgres.

MySQL has quite a few "impure" but useful features. Postgres pretty often comes up with a sane, predictable version some years later (which often does not perform quite as well, but I'll happily take that tradeoff).
If my evidence is that I had it, any attempt to flatten the curve should have happened in January. Effects happening now are just as likely from when we weren't doing anything.
Build This 8-Bit Home Computer with Just 5 Chips
The maybe not obvious point is they have two computer systems, one that manages the "edutainment", one for the drive train. The entertainment one is the one they crashed. I want the web browser updated more than any other single thing on the car. The web browser is separated from the drive train. You can reboot the non-drive train even while driving.
My thinking stems from the conclusion that at this point there is no containing this virus, because this whole thing started with a single infection and transmission is asymptomatic so unless we test all humans & quarantine till we get vaccine this going to spread.

If you accept that premise, then the only solution is to manage hospital capacity. So I propose that we use hospital overload as a high watermark for quarantining the local communities. so basically you initiate quarantine when hospitals are say at 50% of their capacity (because they will peak after quarantine begin). Wait & once they fall below say 10% release the quarantine. Repeat the process until you get herd immunity or vaccine.
I think that pretty much every level with bombers available could be solved without one, if you were sufficiently versed in the edge cases of how the game worked. I could be wrong, it’s been decades.
We see a difference that made us change our minimum specification to 16GB for any machine we buy. We do the same for Win 10 these days. The biggest problem are the browsers and the fun educational companies software that does evil, required things.

A Turing Machine is turing-complete, but it would be inefficient to run Linux on it. We're not talking about raw computability here, but feasibility. And still, I am not aware of anything "running Linux on a GPU", their scheduling engines are not designed for those sorts of workloads.

There was this crazy game ‘Vangers’ that, apart from the most-otherworldly feel I've ever encountered, had terrain in voxel graphics and permanently destructible — and I don't mean shitty Minecraft voxels: https://www.youtube.com/watch?v=P9R7QJ5Sh1o

That was '98. Still wondering why I haven't seen anything like that anymore. I vaguely recall one dude working on a super-detailed engine, down to individual blades of grass and such, but not sure how's the damage model there (that's possibly related to this, but probably not: https://www.youtube.com/watch?v=00gAbgBu8R4). There's also the ‘Teardown’ game: https://www.youtube.com/watch?v=Wc_QC25RM44, and a search for ‘voxel graphics’ on YouTube suggests a few others in this vein. Still not quite the same.

As for mobile Lemmings, the Play store tried to sell them to me just yesterday.
There is a separate computer system. On the S the separate computer system for the drive train has its own screen (in front of the driver). On the 3 they use one display. you can separately reboot the non-drivetrain one.
Had no idea this was possible. I wonder if some more judicious process to make it easier for sellers to use this could stamp out the issue at the source.
4. Measuring what share of people actually develops the disease so we can model forward the spread of the virus.

5. Identify whether there are riskier subpopulations or if everybody is on the same risk level.
It's worth noting, if you either just read the title or are skimming the post, that "never" is used here specifically in the context of a language like Haskell. If your language uses strict evaluation (like most languages), it probably makes sense to use a left fold on lists.
Huh. It has been enabled on every system I've touched so far, didn't realize it wasn't on by default. TIL
My school had a deal where when you signed up for an AP class you had to take the AP test. But if you pass the AP test (3 or higher) the school would reimburse you. I took 5 tests and never paid for one. Including the one where we didn't have a teacher for half a year (long story).

I think this is the fairest way to do it. If you got talent but no money, the opportunity is still there.
you should never trust telemetry or analytics to be unspoofed.
Been following Pigweed for a while now internally. Great testing infrastructure!
How would you outline how you sell your services? What are your complementary strategies to charging more?
> it looks like you the function would be unable to re-use index reads for other column values.

PostgreSQL would have to do a separate sort for each different ORDER BY, yes.

Also, it can't use the the index to scan only some values as it could for DISTINCT ON, because the aggregate is opaque. That may or may not actually matter though.

Another option (though more verbose) is LATERAL plus LIMIT 1.

> Do you have much experience with Postgres WINDOW expressions?

Yes.

SELECT DISTINCT
a,
first_value(b) OVER (PARTITION BY a ORDER BY x),
first_value(c) OVER (PARTITION BY a ORDER BY x DESC)
FROM table

One downside is that I can't use FILTER with those as with aggregates, though sometimes you can hack something together with PARTITION/ORDER BY/RANGE
It depends. If there is competition, things can be good. I live in a place in the US where there are 3 broadband providers, and I pay far less than $100 for a symmetric gigabit connection, and I get it too.

That's too precarious. Once anyone is infected, the whole population goes up. Like that nursing home in Washington.

I'd make more sense to quarantine everyone who gets infected, and then offer to hire those who recover as learn-on-the-job health workers.

We could also have C- and C+ bars, restaurants, theaters, gyms, etc. For lack of a better word, segregation.
Yeah, that doesn't show up anywhere on the page on mobile. Thanks!
You don’t need examples of previous tests to prepare. Even if there was perfect enforcement of no recording devices, no corruption, no breaking in and stealing test papers people would talk about what the test was like, sitting to sitting. Some people retake the test multiple times. This would probably become normative in this case because the practice effect on IQ tests like the SAT is small but real. If people were really motivated you can just pay 100 people to do the test and get them to memorize parts of it, then stitch the parts together afterwards.
This has been my go to as well. Having the log scale is invaluable, as you can get a daily check on if the R value is changing yet (when it drops below a linear fit). I was excited when China was able to kick it. Looking forward to other countries doing the same but looks like we’ll have a few weeks of suffering first.
GPA is already scaled based on income because poor schools give higher GPAs for the same level of knowledge and skill. The study is useless.
They’re not arguing against having an open source spec, they’re just pointing out that you can do the open source ventilator thing while not spreading misinformation.

Please don’t confuse the two. It’s hard enough to fight the misinformation as is without well-intentioned people such as yourself introducing red herrings.

Again, your point is coming from a good place. But we need to be really careful about not accepting misinformation.
The main stupid thing we did was very little testing. Our genius prez kept saying it was no big deal, and they followed policies that in retrospect make it look like they were trying to test less. At least the effective situation in the end was the entire us country has 100 times less testing that the tiny country of S.K.

If we had testing and actively tested 2 months ago we'd have see the problems and started dealing with them more aggressively. We stupidly seemed to follow a policy of no visible harm, no preperations necessary.
Some health professional floated the theory that kids aren’t getting it as much as the rest of the population because they’ve recently been hammered with all the coronaviruses at daycare.

I’m hoping this is true, since it suggests new parents are mostly OK too.
> For the above occupations, the work involved exposes the workers to highly charged/traumatic situations often daily. A good place to start looking for a solution would be how to help these workers regain a balanced view of society.

And clearly, as the GP illustrates, in the cop's case it's at least partially lying by those same cops to fix their own crimes. Or just lying for their own convenience, at the cost of everyone else.

Why do you assume it's any different for the child services worker? They have the power to trade kids, for power, money, or just ego - and are also frequently convicted for doing so. Worse than that, many studies point out that the net effect of child services ... is NEGATIVE for children: there is a lot of statistical proof that children would grow up more successfully if child services didn't exist. Even kids with serious problems at home fare better ... without child services. So it's even worse than the police force, which at least prevents worse.

https://www.theguardian.com/world/2019/jun/27/italian-police...

And why do you assume it's any different for emergency medical worker? In Australia I was blatantly told that I wouldn't get any assistance from an ambulance unless I accepted a morfine injection. That, of course, turned out to be a financial incentive: it allowed them to charge a lot more to insurance. Of course it also prevented treatment (because doctors assumed I had abdominal pain because I was drugged. And, sure enough, I was: by THEM ! Of course that wasn't the cause of the pain, but cause + expected result = just sleep it off and go home. To be hit by terrible pain again the day after. This did not happen once, but THREE times)

And to top it off, when it eventually did get correctly diagnosed, 2 weeks later, that morfine DID cause abdominal pain (morfine stops the peristaltic movement. Therefore, if you're on morfine for more than ~12 hours you're in for a very painful bowel movement. If you're on morfine 3 times for 6 hours in a week, it's no different)

And again, at least the police force and emergency medical worker help. They cause a lot of collateral damage, but at least it prevents worse. Child services ... causes a lot more damage than they fix. So ESPECIALLY that person should shut the fuck up about how bad society is and take a good long look at themselves.
There have been reports, but it’s not to my knowledge clear whether the people who’ve tested positive after being considered recovered were experiencing something else, like a false positive before/after, or weren’t in fact fully recovered.
When I say "replacing" I mean in terms of the weight they carry in admissions.
I'm curious why you needed the absolute smallest PDF file for testing? As an intellectual exercise, golfing the PDF format sounds like a bit of fun, but given that https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pd... is 13KB, I would think you could load that in a test suite on pretty much any reasonable, non-embedded platform. And, why would you want to load it on an embedded platform, anyway?
Inslee is Washington also seems to be doing a good job in similar ways to those too.

Fascinating. In this time when everything is seemingly discoverable online, these odd mysteries that seeking have no link seem vaguely disconcerting. But the pre-internet world was mostly like that. We just didn't know it then.

It reminded me of the search for "The Footage" in William Gibson's book Pattern Recognition.
