That would not be the effect of a false positive.

In any case, these tests would be used to confirm or rule out SARS-CoV-2 as the cause of someone's symptoms. They wouldn't be used for routine screening of asymptomatic people.

"Qualatative detection of COVID-19’s IgM and IgG antibodies"

I hope their test kits are more carefully made than their website.

I mean, normally I know it's in poor taste to criticize someone's spelling, since what really matters is their ideas, not their educational background or learning disabilities. But I think this case is an exception: we're talking about a company who's claiming to offer a solution to the biggest problem in a century — a solution that requires extreme and exacting quality-control processes to make sure it functions correctly. An obvious spelling error on the front page of their website could, of course, be a fluke; but it bespeaks a company whose expertise does not include extreme and exacting quality-control processes.

> I'm sure a lot of vocalists at the time were going for that style.

Well, that's the thing. It's not identifiably any band that I have heard before, but it's generically like a lot of them. What's the point of listing all the influences of this band that didn't make it to the big time?

It sounds familiar because it's derivative of lots of things that were happening at the time. New bands take a while to find their own voice, so in the early demos you hear the bands and songs that influenced them. Some (maybe most) never make it past that.

I can picture it as a band played gigs for a year around their home town, made a demo or two, one of which got played on local radio and there it is. It's not in any way uncommon.

I've had an idea for a while now to have a website that only has a text input like this to allow simultaneously building a website and a voice assistant (Alexa/Google Home) plugin. The development is much faster because it's the same back end for both apps, gives a standardized UI, and the auto fill on the website teaches what is possible on the voice assistant.
Why did US govt not adopt WHO's Covid-19 Test kit?
My theory: In USA healthcare system is optimized to enrich big pharma, healthcare system is not optimized to get care to those who need it, as fast as possible.
If a drug company that is owned by investors on Wall-street makes test-kit, the company will charge customers in USA hundreds of dollars more than the one designed by WHO. This will enrich all share-holders of that company.
The delay between rejecting WHO's test kit and developing own test kit, would have caused undetected spread of virus for few weeks or months.
Is it as simple as this?
I'm curious what you're basing the 1 week off of?

As far as I can tell the company isn't reporting any data about how long it takes, but they think that it is likely to be similar to SARS per their manuscript: https://coronachecktest.com/wp-content/uploads/2020/03/Devel...

> It was reported that after SARS infection, IgM antibody could be detected in patient blood after 3-6 days and IgG could be detected after 8 days. Since COVID-19 belongs to the same large family of viruses as those that cause the MERS and SARS outbreak, we assume its antibody generation process is similar, and detection of the IgG and IgM antibody against SARS-CoV-2 will be an indication of infection.
Notice that the CA style shelter in place has an uptick at the end. Once you let people out it starts right where it left off. My assumption is that this thing is not going to be eradicated and is highly contagious, so the only way it will stop is once there are enough people vaccinated or previously infected so the exponential decays. Under those assumptions, slowing it serves two purposes. One is to prevent deaths due to overwhelmed treatment facilities. The other is to prevent it from just hitting everyone. Maybe only 20-60 percent of the population needs immunity to stop it, but if it runs rampant we could overshoot that. I'm sure there are other reasons to slow it, and other models, other assumptions, etc...
Scientists make mistakes. Scientists change their mind in the light of the evidence. Your distrust of this scientist is distrust of science. Please, don't do this.

> For good and for ill, it is Constitutionally problematic to "lock down" an entire state

Not particularly, curfew and similar restrictions are common emergency measures, and their is no Constitutional difference for greater scale except that it reduces the possibility of it being covert discrimination. And, even if it was, Cuomo had one of the most pressing needs to do it of any state, and was slower than some others. Now, I'm not arguing he was negligent, but he's not a head-and-shoulders above everyone else standout the way he's been portrayed upthread, either.

> On the other hand, the state can totally shut down businesses

Cuomo was slow at that, too.

> I will further note that for Cuomo to be criminally prosecuted, he would need to commit some crime

Untrue. People are criminally prosecuted (and even convicted) without committing crimes all the time. He'd have to be accused of a crime, though.
Mob rule killed Socrates
"Strong" is usually defined in terms of output. And I think we tend to forget that economy is literally people going around their day-to-day things - we tend to forget about that because our abstract models of it are, well, abstract. But if you, say, tell half of your population to not work, that's half of your economy. Not only that, but it's the half that actually produces physical goods. Take a strong man, and paralyze them waist down - are they still strong? Does it mean they weren't strong before?

The more interesting question is how much of our economy is literally waste. I suspect we'll find out.

Ask HN: What is the best Covid-19 dashboard?
I found some online, but many of them lack some important numbers? Do you know any dashboards that 1) are regulary updated, 2) show the numbers over time, 3) show the rate per 100.000 inhabitants, 4) show the number of people tested?
This blows my mind. This is probably a naive thought; This technique looks like it could be combined with robotics to help it navigate through its environment.

I'd also like to see what it does when you give it multiple views of scenes in a video game. Some from the direct pictures and some from pictures of the monitor.

The "Best endgame" you describe is exactly the goal. We lockdown now so that we can buy time to get tests and tracing systems setup. Then we can start to open up everything again and control hotspots with aggressive testing and individual quarantine (as opposed to the blanket quarantine we are doing now). With good testing/tracing coverage, we can stop the virus from spreading exponentially for more than a few hops.

Also locking down everything DOES stop the exponential spread. That's the whole point. If you don't see other people, you aren't spreading the disease, reducing the rate of new infections. If each infected person infects less than 1 other person on average, we'll have stopped the spread. China and SK have already succeeded in this.

Yes, and more to the point, the doubling of the price appears to be before it was known (to the manufacturer) it was a potential treatment for COVID-19.
One reason people seem to be missing for why antibody tests are very useful is it will allow us to confirm those that are now immune. We can’t get this from the RNA testing because it’s primarily being used on only symptomatic people at the time they have symptoms (and then only if they can get the test which typically means severe symptoms)

But if we start to test widely for antibodies we can start to clear people from this effective quarantine/lock down situation we are going through. Those people can then start to go back to regular life (what’s left of it), moving around as normal, doing work helping others, so on, and that will help all of us (and of course the economy).

I don’t know if this is something that anyone official is talking about yet, but it seems like it should be.
It's completely relevant. The original Debian issue was the same general thing, with the distro packaging QL alongside an incompatible gstreamer leading to bug reports for the dev: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=421167#15
They need to be free, universal, and possibly mandated in some areas.

Given the 'cost' is shutting down the economy and 1 trillion Fed bailout, it's probably worth widespread distribution of these things, and nailing down 'everyone' who has it, just as S. Korea is doing. They have not 'shut down' their country, they're just aggressive at going after cases.
Why? That's how the test kit works. It develops colored stripes that you QUALITATIVELY interpret. There is interpretation in the meaning of the saturation of the strip color.

Developers paying attention to keyboard shortcuts is a fit-and-finish metric. I'd even go so far as to suggest it's a good indicator of whether the developer actually cares about their users.

Windows itself did a great job of keyboard shortcut consistency through Windows 7. Windows 8 and beyond, however, have been less so.

Pressing ALT-F4 while Windows Explorer has focus on Windows Server 2019 and finding that you're rudely logged-off with not warning (which has something to do with UAC settings, and can be replicated on Windows Server 2012 R2 w/ the "Desktop Experience" feature enabled) gave me a very "Gee, these guys really don't care about me" kind of feeling. There are others, but they're not coming to me right now.
GPA is difficult, because there's no uniform standard. A 3.9 GPA from Caltech is much more impressive than a 3.9 GPA from Harvard (where there's serious grade inflation), but then again, you have to look carefully at which specific courses went into that GPA. But how do you compare those numbers to a grade of 15/20 from a French university, or a 1.1 from a German university, or some other country whose system you don't know?

Undergrad research (including a published first-author paper) is almost a requirement now for entry into many top programs. But you have to know the research group the student worked with, and you get applications from all over the world.

The subject GRE is a uniform quantitative baseline. It isn't everything (or even most of everything), but it is a somewhat objective standard that can at least flag applicants who might have real difficulty in a top program.

The thing is, I've heard "equity" arguments for disregarding not only the subject GRE, but also published research ("Not everyone has the opportunity to do research as an undergrad") and letters of reference ("Letter writers suffer from implicit bias"). The "equity" advocates seem to want to throw out every piece of relevant information. Of course, that makes it easier to hit whatever targets "equity" requires.
It also means that, if that number is correct, 8.23% of not-yet-infected people will test positive. At a time when only 0.01% of people are infected, that means that 8.2301% of people will test positive, and of those people, on average one person† of every 82301 people will have the infection; the other 82300 are all false positives. They'll need to improve that for this to be useful, since at the time 1% of the population is infected, you're already suffering the worst catastrophe in a century.

† (well, precisely 0.979 out of every 82300.979 people, but the difference is not significant in this context)
Always good to see companies put some effort into good keyboard navigation!

If you want a keyboard-first interface for your web browser I can recommend Vimium (which I'm sure a lot of you have already heard of). I'm not actually a Vim user (at least not yet), but I rely pretty heavily on Vimium's shortcuts in Firefox nowadays. I started using it when I had a school-provided laptop which had an awful trackpad which was way too slow and annoying to use for my taste.

Is there any evidence beyond the layperson analysis you are submitting here in this comment?

My critique of this analysis is that there is no way you are controlling for all of the factors: different starting dates for community spread, uneven testing / reporting of cases, random luck due to super-spreading events, differences in behaviors between regions, and so on.

Those regulations are buying down risk.

Sure, they could buy them from Home Depot without those regulations. But how do they know they were manufactured to spec? How do they know the manufacturer used the correct alloy?

You aren’t paying for “regulations” you’re paying for quality pedigree. This is also why aerospace work is so expensive. The industry has determined the supply risk is too great without a verifiable level of quality. Quality is expensive, but not as expensive as failure in these industries.
What about your experience with medical professionals, mechanics, etc.? It's all relative.
The Imperial report suggested this exact thing, but by their estimations, we'd still need to have lockdown in effect about 2/3 of the total time to prevent healthcare systems from getting overwhelmed in US and UK.

Okay, but as companies shut down, supply chains are disrupted and employers implement measures to enact social distancing, why wouldn't supply also go down?

Does the GPD going down necessarily mean that there is less demand and not less supply?
Dell's site is a nightmare. Shopping for monitors has been one of the most inexplicably complex affairs I've ever seen. It also doesn't help that any link to their US site redirects to the dell.ca front page, making it extremely difficult to follow links from forums, google searches, etc.
Yeah, but it doesn't enter the public consciousness, and people pretend not to understand.

It's one of the glorious fudges that we all collectively engage in.
Is this a serum or antibody test? If so, this is very good news.

If mass testing occurs we will know very soon the true nature of the disease. For example, after serum testing for H1N1 we learned -- to our horror -- that 1.4 billion people had it. However, it also meant that H1N1 wasn't as dangerous as we thought it was.

I hope this will give the medical community and our governments the clear data we desperately need. The decisions our governments are making are based on unsound data -- we are flying blind.
Hepatotoxic is the correct word. Same root with the meaning liver for the words hepatitis and hepatology.
It is probably useful for getting population statistics and directing higher level actions, or even at some point overquarantining people based on positives and false positives, but people that get a false sense of security are a risk. There was an article about a village leader who tested negative and had 200 villagers come to congratulate him, then he tested positive on a subsequent test.

What I am trying to say is that AirBnb is a solid business that is not at any risk of disappearing. I am moderately sure that they could have turned profitable any minute if they wanted to.

There was a subject on HN yesterday were people were posting offers from AirBnb in excess of 400k per year and from what you are telling me they have 15k+ employees now. Fact is, they're burning money for the sake of growth and metrics.

Can they sustain this and sustain it forever? No, but there are pretty much no business in the world who could, so that's not a reasonable metrics to say they're doing poorly and in danger.

They might get a reality check and cut some fat, like most unicorns playing the VC game get sooner or later, but the company is not at risk of dying.

We don't know.

The period of immunity following infections varies, and this virus is not well understood.
This is an antibody test which will only be positive days after the onset of symptoms.

This is principally useful for several purposes:

1. Figuring out who to isolate in hospitals if the RNA test isn't available in sufficient quantity

2. Understanding who has already recovered from COVID-19 and is thus immune with all that implies in terms of inability to spread the disease and reduced need for PPE

3. Enabling us to confirm continued immunity later this year and understand how long the recovered will remain immune

This is not unique to this company. It's unclear to me whether the price is meaningfully less than competitors.

This thread is helpful for further understanding of the test and its utility:

It's a very memorable experience when a doctor thinks he is helping by telling a person they are recovering from a terminal illness and they and their loved ones take him at his word and then go nuts trying to figure out why symptoms are getting worse.

I've had the FSD computer (HW3) freeze in my X once. The autopilot/TACC, gps location and even the wipersn which are controlled by this even if you're not using auto-wipers (deep rain), stopped working. I had to stop and power off the car for a few minutes to make it work again.

Everything else was fine though so I think they have isolated the driving itself quite well.

I've also had the MCU crash 2-3 times but the two finger salute always fixes it.

My car is 8 months old so these events are quite rare.

Just to clarify a little bit... "At the time, very few object detection models had public implementations" - this is wrong. Almost all object detection models had public implementations starting from 2014, most notably Detectron (Caffe), GoogleNet/SSD (Tensorflow and matlab). Post 2015 when TensorFlow was released, one can find even more implementations.
