I’m having difficulty understanding why SPR would be more scalable than LFAs for this type of frequent screening? And what does the ROC look like for this startup’s SPR assay?

Frankly, I don’t understand how this test is supposed to work, and I’ve used a Biacore! It might be helpful to have a technical explanation available, for domain experts to evaluate.
Not sure that's quite the right model. Everyone can pile into looking up entries in the yellow pages online, and the more people find businesses, the more value the yp has in it's base product vs the costs of buying an entry.

The more people pile into a gym there becomes a point of declining value because you can't get on a machine and the room gets stuffier, conditions worsen.

I think not finding other value enhancing propositions for the yellow pages is mostly about brand stagnation.
Alright so lets unpack this argument, because (1) this is a pretty extreme oversimplification, and (2) the unstated suggestion you make is to quite literally let millions of people die world-wide who wouldn't have otherwise:

> Data is showing that the infection fatality rate is around 0.5%-1%, and is concentrated in older people.

right, "old" (65+?) people are going to die anyway, lets just let them die sooner. How much sooner? Years? Decades? Does this really sound like a cogent counterargument to not letting people die?

Let's ignore the morality aspect of this, which I don't think is in your favor, to put it mildly. I don't really like people suggesting that millions of people should die because "this is sad, but at some point, everyone has to die." Yikes.

But lets pretend we live in a very nauseating reality where older people don't really matter very much. You should still want society shut down to prevent this spreading out of hand because this will easily and thoroughly overwhelm all of our healthcare resources, which will mean hundreds of thousands of people you actually do care about (i.e. non-older people) will also die from lack of medical care either from COVID, pre-existing medical conditions, new medical conditions, etc.

Dang, that really sucks. I was planning on updating my desktop to 20.04 but after reading about Canonical pushing snaps and now this thread basically claiming that moving or renaming the directory is impossible because what is in my opinion a design flaw in the entire system design, I think I'll switch to Manjaro or Arch for my desktop instead.

I am on the rolling releases already but I'm not going to install an LTS version that is so deeply integrated with the distributor while at the same time ignores the directory standards so incredible blatantly.

For controls: development, and especially, standardization.

For aircraft, there's the matteer of movement in three dimensions, with speed, yaw, pitch, and roll controls, as well as communication, navigation, and cabin environment controls. Autos have only two dimensions of freedom and less complex requirements generally, but orders of magnitude more operators with orders of magnitude less training and oversight. Addressing user-base scale is its own complex problem.[1]

To be clear, my list of key elements wasn't asserting equivalence between land vs. air craft, but adding them to fuels and engines as crucial enabling technologies.

A lot of microcontrollers fall into that category. The Cortex-M0 ARM core doesn't have integer multiply or divide, for instance, and it's almost always absent on 8-bit cores like AVR and PIC.
Everyone says "we need more testing", but there's actually very little discussion of how that testing would translate into lower transmission. I'm skeptical any program less aggressive than the one proposed here would get R0 < 1.

Haha, no wonder the dial markings don't match up at all. Now he's telling me what kind of makes & models he's hearing about over the air...)
Strange that the commit is from 2018 but it was only included in the patch level of February 5?

At least Samsung is pretty good about updating patches. Not android versions, no, but at least I still get monthly patches. My S8 already has this one.

Debian has its own set of problems. Like the Chromium package maintainer deciding unilaterally several years ago that installing extensions remotely shouldn't be allowed and gated that standard functionality behind a command ling flag.

There was zero documentation on the change and the error you received attempting to install an extension was basically "operation failed". I discovered the cause only because there was an open bug about it on the Debian bug tracker where the maintainer refused to acknowledge the problem. Eventually, sane minds prevailed and that stupid patch was reverted.

So, unfortunately - you'll end up having to deal with people that refuse to look at things from the user's perspective no matter what distro you use.

And yes - I'm still bitter. :-/

> If it's the owners of these buildings, who checks to ensure compliance?

Who checks to make sure every restaurant follows the standards of cleanliness? They have inspectors who (theoretically) show up randomly, so it ensures most places comply voluntarily, because the cost of getting caught is very high.

A combination of random inspections and steep fines would solve the compliance problem.

Edit: I just had another idea. Offer cash rewards to people who can prove they they weren't tested when entering a public place (which the business pays for via fines). You'd have people running around trying to find missed testing for the cash reward.

Thank you Paul. Two questions :

Does this approach bypass the reagent shortages ?

What are the specificity / sensitivity metrics ?
This is not an analogy. It's just math - the risk of dying from COVID19 if you got it is comparable to the risk of dying this year all things other than COVID19 considered. (approx 0.1% in your twenties, approx 15% in your eighties).

If getting it confers lifelong immunity (a question that does not yet have a definite answer), that means getting it means you compressed the overall risks of two years into one[0], or reduced your life expectancy by one year.

Now, one year is a lot. But the difference in life expectancy between the US (78) and Japan (84) is already six times as much, so the lockdown in that context is about 6 times more expensive (per day, per person) than moving to Japan[1] would have been before COVID19, and no one would have preached the latter.

Here's a conundrum: you can (a) lock yourself at home for 6 months, likely losing your job, potentially keeping in touch through the internet; then come back to "normal" life. (b) give up 6 months of your life expectancy, but go back to your normal life tomorrow. That is, w.r.t life expectancy, you can pause for 6 months and keep those 6 months; or fast forward those 6 months (and thus lose them). Almost everyone I know would pick (b) if there aren't any exception circumstances such as terminal disease. But the western world at large chose (a).

[0] That's not exactly true - depending on some other model parameters; reduction of life expectancy by 6-9 months is more accurate.

[1] It's not guaranteed that moving to Japan would grant you Japanese life expectancy. It is also not guaranteed that the lockdown as practiced really buys you more than a year either.
Eh, I think I found the one you're talking about, and it still looks like a somewhat legitimate looking news site, and according to other sources still gets thousands of pageviews a day. Also, that's such a specific topic, by page 10 most of the results are just somewhat related news articles. Try searching something more general, and the results on page 10 are things that could easily be on the frontpage, probably just don't have dedicated SEO.
I want to see what the other 90% of the internet looks like.
But also, I think they should break traffic down by domains, not pages. For example, does each article on HN count as a new page?

Those bugs seems to be in open source part though. While I agree that open hardware including open drivers are nice to have, it's a much tougher requirement.

What I miss, personally, is some kind of ecosystem along with guides, etc where I can learn how to build Android from sources, put some binary drivers from official image and run it on my phone. May be even some guides how to reverse engineer proprietary drivers and rewrite them as open source.

I am saying the drive for revenue and the programming model of the web have created an abuse vector for user experience. That's all. We know it's true because platforms that have grown dominant on the web (indexing it, for instance) have to build scores and filters as a layer to protect the user from this. AMP is another example of investing in the protection of users. If it hand't been tainted, the user experience wouldn't need this level of protection from it.
This.

I worked on the customer delivery side of a $750M software project that was a steaming pile of shit, with critical defects that were known for a year with zero effort to address. The integrators were paid to deliver a spec, and it took about a year to get change orders created to diverge from the spec.

The old school waterfall outsourcing models are truly awful, but you don’t really understand how bad unless you’ve lived it. Stupid agile religious practices are dumb for any startup type org, but are probably better than the alternatives in many big enterprise scenarios, where the goal is chunk up the work so marginally qualified people can do something.
As I pointed out elsewhere, you're ignoring that Covid-19 is highly infectious, meaning that lots of people get it. Low fatality rates with wildly infectious diseases still mean lots of people dieing.

Of course, as others point out, there's also the enormous strain on the hospital system. Which, I am very curious: are you not aware of what has been going on with the NYC hospitals? Or parts of Italy?
Ask HN: Breaking into data science after years in public sector
I'm 34 years old, have a degree in economics and have worked my entire career in the public sector running the occasional linear regression and doing mainly data wrangling and data cleaning tasks.

I would like get data science role in the private sector, but feel I have nothing tangible to show. I have zero experience working on projects for ‘clients’ or with large datasets or relational databases. I've also never used AWS/Azure or any cloud platform nor had to scale any process. Last but not least, no experience ‘training’ neural networks or any ML algorithm in Python.

Instead, most of my coursework and work experience has focused on working with academics and non-profits. The tool of choice was always Stata (and very rarely R). Small datasets and files saved locally and shared via email have been the norm. I have dabbled with Python/Pandas for basic data cleaning tasks and created a few Tableau databases, but nothing major or ‘scalable’.

I do have a sense that if given a data science role, I could learn on the spot after putting in the hours, especially in the beginning. (I mainly say this because of my econometrics coursework, but of course, there's a lot I would still have to learn.) However, I lack real world data science experience and have nothing to show to convince someone to let me get there in the sense that I would easily be screened out. My age doesn't help either.

Any advice would be welcome. Thank you!
If outsiders want to see whats going on in an Agile team, all they need to do is run the "working software". They don't need to see all the ugly bits under the covers.

Having working software is line two of the Manifesto. They can run it each week and see whats new.

Even better, they can provide feedback on the working software and the team can then quickly respond to that feedback. In a week or two, when the outsider next looks at the working software they will see the software improved.
How Efficient Is EfficientNet?
Actually situations like this are still considered a bug in software. It is always the responsibility of the software to be resilient against externalities.

Oh yeah, I'm not sure how I missed that. Bookmarked that now.
Exactly. While this plan would certainly result in some disruption, it would be a lot less than the current status quo. And you can't really compare it to simply "opening back up" without a plan like this, because the simple fact is that even without government-enforced lockdowns, many (perhaps most) people won't return to a normal level of activity if they don't feel safe doing so.
He's proposing scanning when you enter a public space.

Public spaces generally comply with these types of things because of the fear of getting caught by random inspections and steep fines and penalties.
How can people help you succeed?
Hard to say whether the down votes are because of my attitude or the true belief that PWAs are a viable alternative that should be weighed against native apps.

And yes, I am advocating for a technical regression. I think the web platform has pushed things unnecessarily too far because it cared more about competing with apps then embracing what the web is good for.

If you want proof this is true, look no further than technologies such as AMP that trade away the general usage of these advanced web technologies for something the end user actually wants: a good user experience.

You could also look at the numerous native apps that have mini apps and games that are developed using web technologies. If the web platform delivered features developers needed, these mini experiences could run in embedded web controllers. Instead they are custom webviews with hooks into the native platform to bridge the gap to what developers actually need.

A cultural acceptance of WIP software seems common, in free software communities, in my experience.
Yeah, you make a good point, millions of pages could quite possibly be from the same domain and basically have the same content.

Search by domain, rather than pages, and I think it would be kinda interesting. What kind of websites are up that get barely any visitors? I would be interested in visiting the sites that aren't making any money, and why/how someone is paying for it.

This assumes that "economic activity will restart". Humans won't participate in dangerous activities. They may test the waters e.g. by ggoing to gyms, but as soon as a single case is found they 'll be scared back into their homes. It will happen even more so as the disease spreads and people learn about the death of someone they know. This will happen regardless of how much testing.

If you 're doing contact tracing right, you should need to test very few people per million every day. If you need to do a lot of testing, you ve probably already lost and will be forced to shutdown again. The solution is probably the second: antivirals.

OTOH i wonder what's the effectiveness of optical-based methods to detect viral particles:

Maybe when they tought that none-free drivers opt-in was a good idea, also old kernel / packages.

LTS on Ubuntu was always better than Debian, I mean saying that Ubuntu is just a repackage of Debian is very short sighted, especially on the security side, Canonical security team is top notch.
> If the covid rate equals the regular rate, then the US death rate would effectively double if we simply did nothing.

For one year (or however long it takes to reach herd immunity -- and if longer, then death rates wouldn't double but increase much less). Assuming recovery confers significantly long lasting immunity, which I agree is not a trivial assumption (and one we don't know yet how reasonable).

Definitely not trivial, but -- in context -- means a reduction of life expectancy by less than one year. The US already lags Japan by 6; there's a lot that can be done to improve it by a year, with costs much lower than those currently spent to avoid reducing it by a year.
Romer has called for as much as 30 million tests a day, which I think was based on some simplistic modeling. I think he was targeting everyone in the US being tested every two weeks. I think the two approaches are similar: let's test lots of people all the time, however many X million tests a day that is, so that we can quickly isolate and treat them. People are spreading it before they know they have it, so let's just test everyone all the time and not wait until they have symptoms.
Paul, is there anything HN readers can do to help with this?
It seems like a significant difference -- see how Hong Kong is doing. It needs to be combined with other interventions including social distancing, contact tracing, testing, quarantining. These measures are all additive to each other.

> At most startups, you make less than bigco wages, but have the hope/promise of stock options. But, in ~94% of cases, this is a terrible financial tradeoff.

Ain't that the truth...
Yes, pretty much. But everyone will probably end up writing this at some point. It may as well be in the standard library.
This position truly baffles me. I can understand people who have reservations about tracking everyone with phone apps to do more effective contact tracing. But objecting to widespread, low-cost testing for virus infection as an extension of the surveillance state? I don't even know how to argue against that because it simply doesn't make any sense to me. Right now the population is clamoring for more widespread and effective testing. Why would people rebel against it? You think people would prefer to remain locked down, or to sacrifice 0.5-1%^ of the population, than be regularly tested for infection? Why?

^or whatever the true number ends up being
