How can we spot the "silent spreaders" of SARS-CoV-2 -- the people who are infected and contagious, but have no symptoms? [1] Our digital medicine group at Scripps Research Translational Institute has just launched a health study [2] to explore one possible approach: crowdsourcing data from wearable devices like the Apple Watch and Fitbit, and then attempting to use machine learning (or less grandly, linear regression) to identify COVID-19 infections.

In January, my colleagues at Scripps published a study in the Lancet that used heart rate and sleep data from about 47,000 Fitbit users in the U.S. to predict which areas would be hardest hit by flu. [3] The correlation with actual reports from the Centers for Disease Control was very high: 0.9.

We’re hoping that we can do something similar for COVID-19 infection. In particular, elevated resting heart rate appears to be a reliable indicator of viral infection. [4] We’re wondering whether it might also be a leading indicator, i.e, spiking to a detectable degree before any measurable fever. If it were, we might be able to identify COVID-19 infections in individuals -- and areas with outbreaks -- before people even have any symptoms.

To figure this out, we’re going to need a lot of participants. And that’s really the greatest challenge for us now. A similar project in Germany [5], which was inspired by our Lancet flu study, already has more than 160,000 volunteers. But they have the advantage of being sponsored by a national research institute. We don’t.

If you have suggestions about how we might reach people with wearables who want to help out -- or if you have questions about the DETECT study -- please add them to the comments.

Thanks,
Danny

Lemme guess, are you one of these people?

If so - lol for now.

If not, why is this mental gymnastics?
Why do people in the US limit themselves to SMS or Apple's proprietary messaging platform? That's sounds bizzare to me.

In Europe everyone texts on WhatsApp so nobody is left out.

I certainly neither said, implied, or agreed with that concept, no.
I'm aware that comparison of fingerprints is done by extracting/storing/comparing features. But in 2020 the digitization of fingerprints can/should go without saying and the details of how fingerprints are compared are just a distraction at best for most of the general public.

As for 'digital fingerprint' being a good term for that, I disagree. I think that's a term that's very likely to confuse the layperson. If you search that term on wikipedia you'll find a disambiguation page that lists six options, none of which have anything to do with fingers: Message digest, Device fingerprint, Digital video fingerprinting, Acoustic fingerprint, Canvas fingerprinting, Content ID (algorithm) https://en.wikipedia.org/wiki/Digital_fingerprint

If you search the same on google in a private window, the first two or three pages of results are all about the same computer-related topics as that wikipedia page (the first result is that wikipedia page, and the second is a blog post from Mozilla about browser fingerprinting.) After a few pages I started to find pages about digitized prints of fingers, so I don't doubt that people in the fingerprinting industry use this terminology. Nevertheless I can easily see laypeople being mislead.
How ironic that reading this, I jumped to the Errors of TeX link, something I've read parts of in the past, and then found myself wondering was I in that file?

I am.
I think what really destroyed people was a complete inability to perceive the page as a series of nodes all interconnected with various relationships.

Fair enough. :) I've experienced a similar issue with interview questions where they often floundered on the question because they hadn't ever spent time digging under the surface. For example, I notice that a lot of (typically junior) developers seem to only think of JSON as a representation for hierarchical objects but never really spent time thinking about the typed-ness of its keys/values or the limits of what JSON can actually represent. An interview is a bad time to be confronted with that realization.

I cannot remember if I specifically mentioned refreshing on the DOM methods or not.

Well, it was a long time ago, so I'll give you the benefit of the doubt and just talk about what I've experienced. I go back and forth about how specific I should be about the type of questions I might ask. On the one hand, it seems kind of foundational that someone writing web frontends is aware of the DOM and how it works, even if they never directly interact with it. On the other hand, I think questions need to control as much as possible for the "preparation" factor because some people simply interview better or have more time to study.

It doesn't seem too crazy to me today that a competent FE dev these days might have spent their whole career in React, and therefore they don't really have a strong grasp on the DOM. If you had asked when I first started doing web FE development, that would have been crazy! But frameworks got a lot better and a lot more comprehensive since then.

I recently had an interesting experience asking a question involving dealing with UTF-8 encoding. I figured "everyone knows about UTF-8 right?" I retired the question pretty quickly once I realized that bit manipulation is not actually something you have to be even remotely familiar with in order to be a functional developer today in the vast majority of programming tasks, and therefore it wasn't even a good fizzbuzz-type test.

You're not wrong, but seriously, what is wrong with the world?
Maybe it will be discontinued, now that the loudest promoter of hydrochloroquine has decided to pull their WHO funding...

By that logic, you could just not do the study at all and claim it as evidence of absence. Statistically, it's the same problem. You need data (and lots of it, relative to the noise) to provide evidence of anything.
It was by chance. First, I started teaching English as a foreign language in Europe: that provided a useful background in pedagogy, although has nothing to do with computers. Second, I was offered an adjunct position at a university where I was a student, which gave me a taste of teaching CS.

You'll probably need at least a Master's degree if you want to teach, but a strong industry background might be enough. You might try approaching a local university (don't discriminate, even community colleges need teachers) about teaching one class a semester. If you like it, you can try a better school or go for a full-time position.

You’re totally right!

Everyone here is just making things up!

Egregious sarcasm aside: I owned the 6s after the 5s and it was too large to use comfortably, I kept dropping it, it meant that I had to _only_ use the phone when I wanted to check something- maybe I could get away with just a glance but a quick reply required far too much time unless I used two hands.

So I got a Samsung Galaxy S8 which felt superb in the hand, but was still wayyyy too big, and it saw the pavement in a similar way; I got rid of it because Samsung’s Android is horrible and on the S8 it wasn’t removable and went back to the old form factor SE.

I haven’t dropped this phone once, it’s comfy, it’s light- easy to carry around and very easy to use in one hand while I wait and sip a drink or something.

Anecdote: my girlfriend has an iPhone X and due to the size of the thing she leaves it hanging around the apartment and has to go searching for it each time she wants to use it. It’s simply too uncomfortable to keep in her pocket.

> Some countries like Italy saw a much higher mortality rate, nearing 15% in Italy, I believe, but that was due to the breakdown of the overwhelmed health services

That's one factor. France and Britain have such extreme mortality rates vs case counts because of their very poor testing rates (which has been openly admitted by both nations, this isn't my opinion). Germany's mortality rate is so relatively low in part because of their vast testing program caught a lot more cases.

Britain has probably had between 5x-10x the positive cases that they've reported up to this point. They were only able to test 12,750 people per day as of a week ago. That's a minimum of 1/10th the rate they needed to be at. If the US has had 600,000 positive cases, it really has had 3+ million cases, given the poor rate of testing.
I dont fully agree with this statement, but perhaps the sentiment. I think there are those who are on the fence and doing it monthly can always help. However, I think the bigger struggle is that those interested but not major collectors still get sticker shock whether or not its monthly or not. This is the challenge with all rental models. They advertise "only $25/mo" however when that person says yes I like this, its still $2000 and they are like no thanks.

I took that to mean they obviously weren't suggesting something so conversational as the actual title, but the takeaway is the same and shouldn't be a conclusion taken from the OP comment.
Ask HN: Recommended tutorials or online courses to remote manage Windows PCs?
The small business I work as uses LogMeIn for employee work and system maintenance. (We also started using ConnectWise after this HN post [1])

Does anyone have recommendations of online courses (Coursera, Edx, Pluralsight, etc.) or even blog posts describing the problems which you can recommend?

Of course in this time most of the staff are working remote. And for the most part, everything is working well. But there are a few outliers who are running slow and need TLC.

I know there are electrical outlets which can be controlled remotely. I'd like to hear more about the problem of just not being in the room to pull the plug or see the problem to deal with it.

He was a B-17 navigator during WW2 for 32 missions. After the war, he left the military and went to college. After that he rejoined to become a fighter pilot (what he wanted originally anyway). He flew P-51s, and later transitioned to jet fighters. Flew combat in the Korean War, mostly ground attack missions.

I would have joined the Air Force too, but with my thick glasses the AF told me no way I would be a pilot. So I wound up as a compiler nerd instead :-)
I mean the people who got torched had their freewill removed without warning, death by direct action of God. The issue is not with boundary setting, the issue is with Jesus seemingly calling himself (God) unjust, since freewill doesn't seem like an inviolable issue, if God doesn't have a hard restriction on effecting freewill (which seems to be the case) then he is seemingly the same as the unjust judge? I understand the argument from Job that people aren't to question God because we are simple clay to him, or the argument that people are evil and deserve nothing less than eternal suffering, but since Jesus set the expectation and made the connection directly in Luke it seems like a non-upheld internal measure/standard of God's own?

When I schedule a meeting with more than a few people, the number of open slots within business hours quickly converges to zero. So I have to manually make the decisions as to who is most important to have in that meeting (based on the topic), and who will be conflicting.

Curious how an automated algorithm can make that decision.
Bear in mind that different countries have different interpretations. I'm guessing you're all arguing about a US view. In the UK, "fired" would mean that you lost your job because you did something seriously wrong.

Apple has had a silicone advantage for a while, most androids are 1-2 years behind. :/
I'm not sure "driving an older car" is a very niche case. 3.5mm jacks on car stereos go back literal decades, and my 2019 Jetta still has one (even though it also has Android Auto + CarPlay). Even as far back as cars with cassette players saw people buying cassette tape adapters so people could route 3.5mm audio through the tape deck.

Even in newer cars, it's the same kind of choice reduction you see on phones, though. With a jack you can choose whether you want wired or wireless audio; without a jack you're still with wireless all the time, even when wired would be more convenient.
Watching TV is, for some people, a Very Important Activity

I don't get it myself, but for whatever reason a lot of people do enjoy this. I'm guessing as a coping mechanism. Probably in the same vein as reading books/news, or playing video games etc.

I have an old friend who every night picks out some criterion collection DVD to watch, and posts about it on social media before/during/after.

That said, I have a tablet I use for long-form reading/youtube (90%+ reading) during train/ferry rides > 10 min, but obviously haven't had to use it much recently. Mostly reading.
That there are some factual basis to your assertions, but in aggregate you are missing the boat.

Chinese labor is cheap because it has been a poor country, lacking capital to raise its productivity and labor standards to western levels.

Comparative advantage means both sides benefit when Chinese labor makes goods for the west. They get better paying work, and we get to make our goods cheaper.

Working for Foxconn is a huge improvement in living standards over the rural jobs most of the Chinese workforce comes from.

Environmental protections cost money. It’s far easier for wealthier first world countries to bear those costs without significantly reducing their living standards.

Poor countries, whether it be China, first half 1900s USA, or as we saw previously with the USSR, are more likely to prioritize economic output over environmental protections.

Economic growth is why environmental standards improve over time. It costs proportionately less to increase them, and new technologies also lower costs of enacting tougher restrictions.

As China continues to grow wealthier, it will likely continue to increase its environmental protections. Especially if it ever turns into a real democracy.
This is what I use it for.

As a counterpoint, nearly everyone in my family in medicine still loves it. My parents are surgeons in their sixties who don’t need to work any more. My uncles and aunts are GPs, radiologists, and anesthesiologists. My cousins are GPs, nurses, and anesthesiologists. So that’s a spectrum from 21-65 and almost all of them enjoy their jobs. The things that really bother them are poor administrators etc. They’ll quit jobs over that, but not out of burnout.

I think it’s easy for this to be a fulfilling career if you’re the kind of person who doesn’t get early filtered out.

Yep, plus my phone is just one of many devices that I connect headphones to and I can't be bothered to maintain a collection of adapters. Also, did you know that the firmware on the Lightning->3.5mm adapter can crash?

My basic point about Bluetooth audio is usually this:

In the absence of hardware failures, audio cables are almost 100% reliable. In the absence of hardware failures, Bluetooth still suffers from a variety of random issues.

Bluetooth has its place (I find it useful to walk around the house listening to stuff without carrying a device), but it's certainly not - and won't ever be - a replacement for audio cables.

The reason why you get better yields from being a landlord or investing in shares than from keeping it in the bank is because you also accept risk. These people accepted the risk, and their reward during normal times is a better yield. By bailing them out (and specifically only the ones who also get income tax)
So what happens when we end quarantine in 6 months? We'll just have a COVID epidemic 6 months from now. Isolation does not stop the spead, it only slows the spread.

As soon as isolation is lifted, whether that be in a month or 10 years, the spread will resume. Unless of course either a) herd immunity is developed or b) a vaccine is developed.

We've only ever eradicated one infectious disease in all of human history (smallpox) and we had a vaccine for that. See: https://www.historyofvaccines.org/index.php/content/articles...

I'm not really sure what you mean by "constantly impending obsolescence", but as one anecdote in the face of that: I have plenty of core JS code in production that was written 3-4 years ago. I've gradually improved or changed parts of this codebase but that had absolutely nothing to do with external libraries of which I use very few... this feels very unchanging to me, my code is not about to implode due to any external reasons.

I write my own UI/MVC type code from scratch just because that's the way I roll and my requirements there are a combination of minimal, extremely performance sensitive and in many cases esoteric where I have to write the UI anway so it's not much work compared to forcing existing libraries to do what i want... but if had to I could replace it with some hip and upcoming UI + MVC library and still keep 95% of my core code completely independent and intact.

I think JS world feels like massive churn if 90% of what you are doing is UI UX etc, because that's the interface that can never sit still in the name of progress... either that or you (not you necessarily) are doing it wrong and not separating UI code from your application code (I've seen this happen quite a bit in ye olden angular days where everything becomes attached to angular for no apparent reason, and angular itself is the worst of OOP + MVC where everything is convoluted and difficult to follow).
Defense vs Offense is the quintessential cat & mouse game. If the offense comes up with a new weapon, the defense is forced to come up with a counter. If the defense comes up with a better shield, offense comes up with a bigger bomb.
If I am understanding this correctly, there is no money flowing to rich Americans, but they will have additional opportunities to deduct losses on their 2020 taxes (basically paying less in taxes after a major stock market rout) that would normally need to be spread over future tax returns indefinitely.

However, this will only occur if they took losses, so it is really a discount of ~35% on negative income. This would also apply to someone who is not rich, i.e. a software dev sole proprietor who cashed out big losses in March in the stock market and then applied those losses against their normal income to end up reporting 64k in income instead of 100k (normally 36k in losses would have to be stretched over 12 years of tax returns).

I understand this doesn't fit the narrative, but please comment if it is incorrect instead of downvoting.

That is, not every pharmacy in every country is out, and sometimes a pharmacy is out of a medicine. If that's what you mean by "universal" and "local shortage before" then you're being absurd.

The first 10% to be infected, are also likely to be the highest spreaders (people in close contact with a high amount of strangers). The effect should hopefully be higher than 10% reduction in the reproduction rate.
Ramraj, if you just want it to look good in your room, are you really going to pay several hundred dollars more over time for what you could get a beautiful poster from art.com? This is the challenge all online platforms (not so much galleries) face - people just want something to look good, and that can cost fully framed $120 from art.com. If you're going to spend $400, $1000, $1800, etc you have to care about the artist.
