Why doubt? Why imagine? You know that, for data on big corporation's servers, the NSA already gets a copy of everything - and everything is recorded forever without you really being able to delete it. Why would this be so different for voluntary self-espionage devices (Alex, Dot etc.)?

It a reasonable assumption that a lot more recording happens than is claimed.

Sending a copy of all data to the NSA is apparently a great business decision, especially when National Security Letters demand it.

In the advertising industry harming you is often a great business decision. Dissatisfaction breeds demand.
In Germany insurers are required by law to provide a minimum standard of coverage comparable to some of the best employer-provided healthcare in the US, insurance costs are heavily regulated and progressive, all employers are required to cover part of the cost, treatment price is heavily regulated, and no one can be rejected.

Absolutely none of this is true in the US.
Another study on homemade masks: https://www.researchgate.net/publication/258525804_Testing_t...
"Both masks significantly reduced the number of microorganisms expelled by volunteers, although the surgical mask was 3 times more effective in blocking transmission than the homemade mask. Our findings suggest that a homemade mask should only be considered as a last resort to prevent droplet transmission from infected individuals, but it would be better than no protection."
You're skipping half the recommendation though:

Fwiw, for anyone who’s dabbled with Haskell this is SOP. Any result that could be undefined is returned as a Maybe (Haskell’s version of Option). If this seems odd to anyone, understanding it in Haskell will probably help understand it better in Rust too:

> but Singapore and Honk Kong took significantly more measured approaches which ultimately have also been successful in limiting exposure.

I think Singapore and Hong Kong (and South Korea) were able to aggressively test (e.g. temperature readings at airports), contact trace (e.g. grab location data off phones), force mobile apps for tracking and checking in, etc. All of that gave them the option of a measured approach.

China had to go full in because they realized they had a uncontrolled pandemic brewing for a month before they took any significant action.
I don’t entirely get the cognitive dissonance of worrying about a microphone+speaker sitting on your table when you probably have a microphone+speaker+camera+face-scanner etc... in your pocket.
Same story for most laptops.
You could buy 0.018 Tomahawk missiles for that or treat 54 people for every Tomahawk missile fired.

All of the Tomahawk missiles fired since 2001 would have provided 119.000 people with free Corona treatment.

I am thinking that countries with free healthcare care more about keeping their own people healthy than dropping missiles and misery on other countries people.
It doesn't even matter how sincere they are. False negatives hurt the perception of the product, because then people need to repeat the key word. False positives do not hurt the perception of the product, because the recording occurs silently. Their incentives are aligned against privacy, and so privacy will suffer.
This. Something ridiculous like 95% of surgical masks and 75% of N95 masks are normally imported from China, because theirs were slightly cheaper. Almost all of them have been diverted to domestic use. Now the US, with almost no manufacturing capabilities, has doctors and nurses who are forced to use dubious improvised masks whilst China increases its international influence by selling a small fraction of its output at inflated prices to desperate countries in Europe. I've seen a load of dumb takes on social media blaming this on a lack of "leadership and competent diplomacy", but having a leader who grasps the diplomatic advantage of doing this is no good if your country can't make the damn masks in the first place.
Obviously, any device which is mic'd and connected is a risk. And devices like the echo or whatever google and apple sell have a permanent hot mic' since they keep trying to match the keyword so a "live" indicator would be of very limited use.

Unless the trigger-matching was performed by some sort of tamper-resistant secure module which would also trigger the indicator and not feed any data to the rest of the system, but then you'd have to trust that that is properly implemented as well.

I guess a suspicious mind could be able to check that by looking whether there is traffic between the device and the cloud servers. And the paranoid mind (who wasn't paranoid enough to not have such a device, oddly enough) could only allow the device 'net access when desiring to use its capabilities (though obviously there's no guarantee said device wouldn't have been buffering hours of conversation while offline).

"Promoting simple do-it-yourself masks: an urgent intervention for COVID-19 mitigation" (Svara et al. 2020)

Pre-print available at https://link.medium.com/LY7RRNr2X4

Summary: "We demonstrate that widespread use of masks by the general population could be an effective strategy for slowing down the spread of COVID-19. Since surgical masks might not become available in sufficient numbers quickly enough for general use and sufficient compliance with wearing surgical masks might not be possible everywhere, we argue that simple do-it-yourself designs or commercially available cloth masks could reduce the spread of infection at minimal costs to society."

> great having the butter melt into warm bread

If you plan on keeping it (i.e. you don't eat it all at once) its best to leave it to cool before cutting it open. Even after it comes out the oven the dough in the middle continues to cook from the steam. If you cut into it too early the steam will be released leading to somewhat soggy bread.

Who should decide what we see online?
I don't think the parent's point was that we ignore evidence but that in the absence of evidence (as opposed to evidence suggesting the contrary), we should use priors to guide what we do. In this case, while there are no double blind randomised studies that suggest that widespread mask use reduces R0, priors tell us that masks use protect against infection in other settings.

If we were to weigh the priors, the existing evidence would be leaving towards mask use having a protective effect. The question that we should ask ourselves is, what if the reality turns out to be different? There are 2 scenarios. First, mask use is harmful and the second, mask use has no effect on transmission. The first is very unlikely given what we know and the second will mean that if mask use is encouraged, it will be wasted resources for no gain. If these resources that were wasted were easily obtainable i.e. masks made of old clothing etc, then the downsides aren't serious at all but could have very good upsides if the priors were right.

So I agree, that we should encourage widespread home-made masks use and leave the disposable ones to the healthcare workers.
Fair, but the author is about as well-respected an epidemiologist as you will find.

The article is explaining what the default assumption should be. Empirical data might change that view.

As I wrote elsewhere, my money would be on the opposite if anything. Yes, there are base level science courses in high school. But you can sign on as a chemistry, physics, or mechanical engineering major with very little beyond some basic aptitude and interest.

At many schools, on the other hand, if you're following the CS curriculum you're starting off with topics like algorithms and effectively teaching yourself programming and maybe even how to use computers in parallel. This has changed a lot over time. When I got my non-CS engineering degree way back when, the one computer course I took was really a programming (FORTRAN) course that assumed zero prior knowledge.
Both. First on the device, then in the cloud. The latter determines if it's a "false positive" or not. AFAIK there is no way to remotely start recording up to the cloud.
This person is actually going to pay less than many people who are insured precisely because they’re uninsured.

Someone who is insured in the US is not allowed to negotiate.

This person can call the billing department and say “I can’t pay” and watch that bill plummet.

The 50% or so of Americans who get their healthcare from solid employers will exhaust their deductible but otherwise be generally fine. Then there’s another chunk of people on Medicaid and Medicare (government healthcare for elderly or poor) who would be fine in this situation.

The group of people in the United States who are screwed fall into a few categories: hourly workers who aren’t offered insurance or who are offered bad insurance from their employers, or business owners that have to self insure.

The ACA (Obamacare) attempted to help this situation by making health insurance mandatory and essentially going the route of Germany, but the mandate has been handicapped by numerous compromises in the bill itself, court rulings, and political turmoil. Also the high unregulated cost of drugs doesn’t help. It was not able to defeat the for-profit health insurance industry.

It’s wild to me that these political parties that claim to be pro-business don’t support separating healthcare coverage from employment. This is probably because of status-quo lobbying and a desire to keep people wage enslaved until retirement age.
How many questions did you do with pen and paper, without access to any outside help (book/tutors/videos)? If you start with trivially easy questions (d(x^2)/dx = 2x) and do 1000-2000 questions with very minutely increasing difficulty level, I am sure you would ultimately pass the course.

Questions you do with others, or examples from the book are useful for conceptual clarity, but that clarity can only be guaranteed to be solidified if you successfully do questions without help.

I'm wondering if the claim that we will have two times the number infections after the inflection point is seen will actually be worse. I have a feeling when people see there is an inflection point, they will relax their precautions and make it worse.

Now, honestly - is this REALLY a corona victim?
Now check the data from Italy - most deaths were like that, and most of them could have equally died from the flu/common cold/brain stroke/just being old.

I'm also 26, and I definitely relate to the teenage IM experience. I think the problem with phone calls is that it's an unnatural level of focus to give someone you don't know well. when you meet face-to-face, there's always some little distractions available to fill the gaps in the conversation. silence is way worse without context; after fifteen seconds or so, the other person will say "hey, are you still there?" I also find myself missing one word out of every other sentence the person says, so there's a lot of backtracking.

as an aside, I've noticed that my cohort of people who grew up sending hundreds of messages/texts to their friends every night don't really interact that way anymore over text. back then if the person was online, they would usually respond immediately and you could exchange a lot of information really fast. now every response seems to take a few minutes or an hour (I do this myself too, don't mean to blame anyone). it has the weird effect of making text a less useful way to communicate than it was ten or fifteen years ago. I guess when everything is immediate and urgent, nothing is?

> In settings where facemasks are not available, HCP might use homemade masks (e.g., bandana, scarf) for care of patients with COVID-19 as a last resort. However, homemade masks are not considered PPE, since their capability to protect HCP is unknown. Caution should be exercised when considering this option.

https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppe-strategy/f...

This is because the medical industry needs proven methods, and they still suggest homemade masks as a last resort. Maybe we should all be wearing homemade masks in public.

How can China become zeroth world shortly when half of the country is still living in third world conditions? I suppose if you only consider how the wealthiest in Shanghai and other Tier 1 cities live their lives then yes China is approaching parity with the West but that ignores that America's per capita income is almost 5 times higher than China's.

China also has the nasty problem of many of its best and brightest wanting to come to America and the West where they will have political freedom and more broadly freedom of expression, something that cannot be bought in China no matter how wealthy one becomes.

Wrong threat model. Those devices only record maliciously if they're hacked. Smart speakers/home assistants inadvertenly record during normal operation. See: all the news stories about their owners discovering their recordings on their google/amazon account.
For most of the people in the world, Internet is already available through land lines or cellular service. OneWeb has very little ability to extract monopoly rents from them.

But both sides are not relevant to the article - whether the business case is solid or not in the long run, they are running out of money in the short term.
It is a nuanced issue though. There are recommendations from the World Health Organisation which say that in a community setting, for a well person “a medical mask is not required, as no evidence is
available on its usefulness to protect non-sick persons“, but that a person with respiratory symptoms should wear a mask [1].

In a medical setting (or very close contact, like a few metres or so) they do help in both directions, this is standard “droplet precautions” one usually takes with a patient.

So while I agree with you that it does help in the medical setting, there is really no evidence that wearing a mask on the street protects yourself, rather than protecting others.

I would argue the opposite is the case. The disease affects basically all countries, so what matters is the global supply of these goods. So we are better off if countries can specialize on their respective competitive advantages. In the scenario you propose, every country would have their own very inefficient mask industry which would now be just as or even more overwhelmed.

Spocket Dropshipping Review 2020 Everything About US and EU Suppliers
The biggest challenge is to overcome the mental block of decades of onetime use masks that have to be disposed in incinerators and be produced by ISO 9001 certified medical factories.

During world war 2 it was normal to use reusable cotton masks. They just need to be put into boiling water for a few minutes to kill sars-cov-2 at 100%.

You should try to get into touch with C. Drosten from Charité hospital Berlin. He recently stated in an interview that self-made masks could have a certain value, so he is not totally averse to this concept and Spahn [1] will listen to him.

China has been promoting it, now czech republic is doing it. If Germany also starts promoting it, that will help immensely.

The same goes for the hand sanitizer, any +70% alcohol/ethanol will do. No need to be from a factory with medical certifications.

I am in France, there is a total lock down here but police still wears no masks and so does nobody else. Super markets have no hand sanitizer at the entrance so the virus will continue to spread.

Masks cost nothing compared to the economic damage of the shut down.
