A test might have a high false positive rate, ie “low specificity”, but can still have “high sensitivity”.

That would mean that while you catch most cases of the virus, you’d also get a bunch of false positives. Flipping a coin as a hypothetical test would give false positives and negatives, or low specificity and low sensitivity.
You can make your own pcr machine with thermometers, 3 pots of water on your stove, and a stop watch
Assuming immunity, you could take care of your parents, grandparents and other high-risk people. You’d have to balance the risk of a false-positive test and wrong assumptions about immunity against the risk of someone from a high risk group running errands.

So the 24% of the US population aged 0-18 is just as likely to die as the "confirmed" cases of COVID-19 in Italy? If anyone does anything but dismiss this stupid ass math, they should panic.
> People who are elderly or have health conditions that put them at high risk could isolate themselves for the next several months while the virus makes its way through the population... High risk individuals have a personal responsibility to isolate and protect themselves.

What people don't seem to get is that this was best-practice even before COVID-19. Influenza also disproportionately affects people with high-risk health profiles and there are millions of cases in the US every year, already, with thousands to tens of thousands of deaths.
Coronavirus Testing in the U.S.: What You Need to Know
While corporate farming gets trotted out as the Boogeyman anytime subsidies are discussed, and is indeed an issue, there's still a lot of non-corporate farming.

And it's a hard life.

You go into debt to buy machinery and raw materials (seed, fertilizer, pesticide) you need to generate competitive yields...

Then it doesn't rain. Or it rains too much. Or the weather is too good in Asia, depressing the global price.

And all it takes is a few years of the above, and the bank is foreclosing on property that may have been handed down to you through generations of family,

How does that make you feel as a person? And even if everything goes right, what does worrying about that constantly do to you?

Farm subsidies are a messy business, fraught with peril, but farmers can't just up and move like most of us. So I'm not unsympathetic to the underlying compassionate goal (even if the realization may be perverted).

I guess the closest analogy for many would be being a web dev, if browsers decided to randomize their compatibility with all standards every year. And you needed to take out a loan for a laptop and tooling.

>A test needs to be materially more accurate than the odds of having the disease to be worth anything.

Shouldn't it just need to be better than 50/50?

>Classic thought experiment: if 0.0001% of the population has a disease and a test is 99% effective and you test positive, what are the odds you have the disease? Answer: 1%.

My odds still changed dramatically and the cost of a false positive is just me hanging out at home and not visiting my parents. I'm not getting a biopsy or taking expensive medicene.

The resolution on Netflix is not a useful indicator of anything (other than an upper bound on image quality). The "1080" Netflix for me usually looks nothing like the average FHD encode of a movie through other channels. A Netflix "4k" stream downscaled to 1080p would probably be closer to normal FHD encode quality.

This is not really surprising as most of the audience is very insensitive to quality.

(Disclaimer: No medical training. Former analytical chemist.) Rapid test kits like these are your best bet if you want to go the DIY route. The only caveats I have are:

1) Unsure of the amount of blood required for this test. If it's just a pin prick you're fine, but if it requires a whole vial of blood, you will end up with some pretty nasty cuts trying to withdraw enough blood for the test.

2) Antibody tests such as these are inherently limited in their reliability. Not as reliable as the PCR tests, and that goes doubly so for these field litmus style tests. All it's really telling you is you how your body has reacted to potential exposures. A near-miss infection would show a false positive. It also takes time, so recent infections can give you a false negative.

3) If everyone on HN buys one of these because of this post, we will be depleting the available stock of these tests that could otherwise be used to save lives. Anything medical is going to be very scarce for the next several months, and we all need to do our part to help assuage the problem.
I call bullshit on this.

Ask any user if they would prefer an upgradeable device to one that cannot be, they will opt for the upgradeable one.

That is why they were forced to bring back the RAM slots after the failure of Mac Mini 2014 (which had soldered RAM).

Apple does this purely to make more money - they have to spend less on parts if everything is soldered, they can charge an obnoxious amount for more memory and it helps with planned obsolescence.

The current mac mini would sell more if they had user upgradeable SSD. But it is obviously more profitable for Apple to offer soldered one's even if it sells less.
As others have noted, the problems are with specific ISPs and their underdimensioned last mile network and/or backhaul.

A modern submarine cable, like Google's new Dunant transantlantic cable, has 250 Tbps of bandwidth. For reference, the largest Internet Exchange in Europe, DE-CIX, just reported a new traffic record of 9 Tbps.

So, no, anything using fiber isn'ta bottleneck. You can fit all of DE-CIX traffic on a single strand of fiber with off the shelf gear.
Neat project!

I was hoping of building a similar one using a simple LCD [https://robu.in/product/3-5-touch-screen-lcd-raspberry-pi/] display, with a way to even showcase urgency/priority - and list at least next three events lined up for the day.

Our service (feeder.co) got banned in China last week. We didn’t make the connection regarding the timing immediately, but it makes sense that they are on the offensive with regards to restricting the free flow of information.

As another slap in the face, Apple also removed our app from the China app store, citing that our app was deemed illegal in China (an RSS reader???). Further cementing my opinion of the dangers Apple’s monopolastic position. We asked to see the legal complaint from the government that triggered this, but have not complied.

This is pure bullshit. If Netflix won't commit to it's part of the deal (FULL HD and 4K) then why should I commit to my part (13.99 monthly)?

You cannot decide by yourself to lower the quality of your services and keep the price same.

Sometimes I wish I had enough money and time to seek "legal retribution" from these type of situations. I would love for this case to make it to the European Court in Strasbourg.

In the Battle Against Coronavirus, Humanity Lacks Leadership
Same here - does anyone know which tool produces output like this?
well first, you'd avoid threads like this that throw trumped-up early/misleading numbers around to scare the crap out of people. but realize that everyday risks, like getting into a car, are non-trivial too (~1 in 100 lifetime risk of dying in a car accident), but we do them anyway.

more to the point, epidemiologists will eventually reach concensus that the infection rate is under control (close to linear, R0≈1, i imagine). most 80+ year olds might need to stay cautious for the rest of their lives (depending on both the actual epidemiology and treatment/prevention options we develop), but that's true of a wide array of threats, like cancer, heart disease, or even just falling.

so basically, it depends on your risk tolerance once we have enough information to determine the actual risks of dying (vs the guestimates we have so far).

" Diseases don't magically stop themselves."

No, but they usually stop, when the immune system is done fighting them, either successfully or not. And pandemies usually stop, when enough people build up immunity, or failed doing so. Or when the disease is so deadly it kills quicker than it can spread. Which is here not at all the case.

So even if nobody would be doing anything, this disease would eventually go away.

It is "only" a question of how many casualties it will take. And we are discussing the cost/benefit of the measures to society as a whole.
Shutting everything down has real costs, too.

Open Source Goes Mainstream – How Sharing Is Shaping the Future of Music
Remember that scene from the Chernobyl series where they messure the radiaton and say it is only 3.6 roentgen — which oddly happens to be around the maximum their device can messure?

This is the situation with tested cases now. You can assume that there is no nation on earthq where the number of tested cases is an accurate representation of what is really going on. Deaths are far more accurate but lag behind ehat is going on by two weeks. And two weeks is a long time with something that grows exponentially.

The bad thing about this is, that this logic is flipped on it's head at times: my girlfriend had all the symptoms just like 6 of her alumni — not a single of them could get tested. And while they where still in bed their university proudly issued a press statement stating they have zero cases of Corona. Yeah — if you are not testing you will have zero confirmed cases, that is the way it is.

The dangerous thing here isn't the current number of cases, but the insecurity about it. If you have a huge number of people starting to get ill today your hospitals will fall apart in two weeks time. Doctors will have to send people home to die, like in Italy visitora can no longer be handled, people no lomger be burried — this is not a joke.

I see that note in the comment, but I don't understand how Germany can be a coffee exporter when they don't grow coffee there. They can only export as much coffee as they import.

This sounds like a warehousing and shipping operation to me. Calling Germany an exporter seems like calling an Amazon fulfillment center a "manufacturer" of the products they ship to customers. Or calling Sweet Maria's or Coffee Bean Corral or Happy Mug coffee "growers".

But maybe I don't understand the terminology, and I am definitely out of the loop on mass market coffee.

Actually, Tom of Sweet Maria's did try to grow his own coffee here in California, with hilarious results. Behold, Finca West Oakland:

According to a recent study from Columbia University up to 86% cases are undetected based on pre-lockdown Chinese data. That would bring this number down to ~1.1%. That is in the oldest-skewing population out there, barely any containment (assuming 14 days infection to death), and with overwhelmed healthcare capacity.
Frankly I didn't even expect it to be this low, I thought it was supposed to be closer to 2.5-3% after healthcare collapse and 0.5% before.

Don't you think it's okay for us to be slightly understanding and forgiving that there are some individuals and companies that aren't simply capable of flawlessly and immediately adjusting to major changes in their realities at the drop of a hat? I'm sure their usage is through the roof, and they probably didn't predict a pandemic with quarantines into their infrastructure improvements modeled around predictable usage.

Also, it wouldn't surprise me at all if ISPs are also feeling a bit of a strain, and are putting some degree of pressure on streaming platforms to lighten their loads if possible.
At least in my country (PL), I was told the laboratory needs to be certified for work with infectious material at a certain standard (you don't want the virus to spread to the people running the test). So while most hospitals have a rt-pcr thermocycler, there are only a handful of labs equipped with personal protection systems for working with live viruses and having the established protocols to avoid sample contamination etc.

I suppose some of those restrictions will be relaxed to include research labs when it's necessary to increase capacity.

The test itself could be reliably run by any phd student or lab analyst.
If R0 is driven below 1 the virus will theoretically fizzle out. In practice, it's possible that sub clusters with R0 > 1 will exist that will restart a transmission chain.

"Without contact tracing and isolation of positive cases a lockdown won’t work."

Why? In a total lockdown situation, the positive cases might infect their close people the live with, but not really anyone else.
And in a half lockdown, with still going out/shopping ... the infection rate is much slowed, if a high enough percentage of the infected isolate enough. That is all that we want, I thought.

Keep in mind that if you get an eviction notice in your record, that can make it harder to find a place to stay the next time you want to get a new place. In 2009 when I could no longer afford to pay rent, I chose to leave my apartment voluntary to avoid getting an eviction notice. That was critical a couple months later when I got a dumpy-but-better-than-nothing place to stay that checked to see if I had previously been evicted.

Looks like Apple didn't learn its lesson with the Mac Mini 2014 that had soldered everything and was a FLOP. The later versions reverted to upgradeable RAM again, but soldered SSD.

And that is why these Mac Mini aren't selling as expected - because users want upgradeable computers. And aren't as much of a fool as Apple believes to pay the insane high prices Apple charges for its soldered SSD in these devices.

How does this pair with Netflix's announcement that they're slowing down their streaming in the EU?

Something I've thought about is that Netflix gets paid a single subscription fee, and in return they have to provide unlimited video streaming for a month. There is no incentive to keep you watching other to make sure you stay interested enough in subscribing again for the next month.

Youtube, on the other hand, gets paid for every video you watch through advertisements. There's no limit on how much profit that can be made from a user in a given month, and so there is a heavy incentive to get you to watch as much content as possible, as there's no cap on the maximum profit possible.
