None of the images will load in the article. I am getting gnarly timeouts with the NYT CDN. Anyone else having trouble there?
As has already been talked about on HN, during Ebola, research was done into any mask.

And yes normal masks do work.

Once again the medical community needed 100% and people thinking of they are clever because they know a factoid are hurting reality.

Everything about this story is awesome, especially the fact that you used the same logo from the punk band.
Why wouldn't you as an investor, borrow against your equity holding at a low interest rate? Using the companies balance sheet seems like a mechanism to avoid liability/long-term obligations on the loan rather than producing a net economic benefit.
Even the N95 are not 100% proof, even if used correctly. Any barrier helps, and the claim that mask use promotes false confidence is highly dubious.
You do know what they would prefer, you just can't accept that there are other ways of humans relating to each other than usury
It seems to me that this is a pretty good opportunity for remote companies to have a competitive advantage in the job market. The question is, how many remote jobs exist and how many can be created in a recession?
Business Idea that can fight Covid
Take a look at this:

If a proper kit like this can be designed that uses positive air pressure, can be installed in various makes/models of cars, and priced at $99, this could sell hundreds of thousands of kits to all the Uber/Lyft drivers out there. It would also go a long way in helping public health. This seems like a no brainer to fund this-- I'm thinking that a couple smart engineers could do this fairly quickly. It doesn't have to last for years or anything-- just a couple months and it would pay for itself for the drivers (and Lyft/Uber could reimburse for it potentially as a service to riders).
A “superpower” who can’t seem make enough masks to protect its own medical professionals from a pandemic. It’s an interesting situation.
How can you in once sentence say we can employ workers previously displaced by automation, and in the next sentence assert that we can produce these goods at a competitive price with automation?
They lost me at the first sentence:
"If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection."

Without being tested, how can you possibly know if you are healthy?..

What a harmful, irresponsible guidance!
Who is being replaced by automation and becoming forced to rely on the gig economy?
I am not so sure because the cost of keeping the in-house manufacturing is also high. Consider military industrial complex, a bunch of companies had been kept alive through exclusive government contracts for 60+ years [1]. The result are companies optimizing for lobbying for maximum government dollars instead of efficiency or innovation. For example spreading the supply chain across every state: https://twitter.com/VP/status/971876888447725568?ref_src=tws...

I believe fragmentation costs of the supply chain are incredibly high. Especially when the supply chain is top down and sources complex components. A problem with the supplier causes the whole project to be delayed. I think this is a major contributing reason of some recent mega-project delays (SLS, F35, James Webb [2], your favorite mega-project here[3]...)

1. Since 1961 per Wikipedia, https://en.wikipedia.org/wiki/Military%E2%80%93industrial_co...

2. Nobody built one before, but I feel like a lot of the screw ups could have been avoided.

3. Being a little facetious, mega-projects are hard.

Does one of the n95 cotton candy machines even exist in the US?

I would love to see the specs for them made free and open so anyone could attempt to produce one and then have it vetted.

Contributing to e.g. firmware code for the thing is like the only meaningful thing I could put my skills towards in this epidemic. It would be an honor to do so.
This statement: "Just because you can breed fragile animals for narrow purposes does not mean you can breed a better human."

> The income from the landlord is payment for his/her obligations

Read my post again. The rent holiday goes hand in hand with a debt holiday. That's the only way this works. Tenants don't have to pay rent, and landowners don't have to pay a mortgage.

Sure some businesses will fail as a result of this, but far more (on a massive scale) will fail if you don't do this.
Just send mail with any advice you have to the address at the bottom of the site. He may not agree with you, but he's more than reasonable about responding (everything in the inbox is read), and it will do more good (and probably get you more goodwill) than campaigning for policy changes in the middle of random threads.

It's also worth considering, when thinking about why it hasn't been banned, whether or not the main value from the threads (assuming the perfect source) would be from the link or the comments.

For some types of submission, it's the link: personal blog updates, academic papers, interesting technical achievements, detailed research, so on.

For others, it's the comments: company updates, interesting world news, most things happening in real-time, obituaries, so forth.

For others still, it's tied: blog posts on historical subjects, 'Show HN:' posts, submissions about different ways of doing things than mainstream methods.

Product launches, from my perspective, fall in the "Value in Comments" category. So then you have to decide whether it's worth the trade-off. By banning TechCrunch, would the site lose comment value?

Looking at this one, you'd really be missing some good comments by getting rid of TechCrunch links; there are all sorts of anecdotes about the product in this thread, and there are a bunch of interesting anecdotes about competing products as well.
Would be much less of a problem if we actually stockpiled enough masks like we were supposed to.
As an independent dev team working with Microsoft Games in 2002-2003, we used RAID to ship Rise of Nations. It was great! Rockin' fast compared with any web tool now and batch operations were near instant. Sadly it was utterly insecure for remote use and it went away after that game.
Oh come on, "nobody cared last month"?

The problem is that there's lots of regulatory capture in the medical industry and that lots of people don't mind it so long as they get to elect people that say the things they want to hear. Plenty of people care, just not a voting majority.
It was torture. Bimodal is right.
The bug puns were everywhere!

When I started working at Industrial Light and Magic in 1998, there was no bug tracker in regular use. I ended up building a bug tracker in Python called "Roundup" (inspired by a program by Alan Trombla, who came up with the name). To create the thinnest veneer of plausible deniability in case the bug spray lawyers came after us, the icon was a little spinning GIF animation of a cowboy on a horse, lasso curled in the air.

I only stayed at ILM for two years, but Roundup remained still in use as the ILM software department's main issue tracking system long after I left, at least 6 years later. It was one of the early issue tracking systems that made it easy to subscribe to any issue, so you'd get e-mail notifications whenever the issue was updated.

The issue identifiers were numbers prefixed with a code to indicate the affected software project, like "REN003" for a bug in the rendering system. Three digits, of course, because I could hardly imagine that a single project could ever have more than a thousand bugs!

I remember that along with statuses like "in progress" and "done", we had a status I've never seen anywhere else: "cbb". As in "done, but could be better." What optimistic software engineers we were back then!
I believe so, yes.

When the hard constraint is not losing profit, many things are difficult to do.
To bad this requires nightly.
Let's imagine you are a medical professional at a drive-through Corona testing facility, like the ones they just announced will be in Walmart parking lots across the country. You get fully suited up head to toe including N95 mask, googles, etc. You take a sample from ONE person, that person leaves, you now take off every piece of gear and put on a new set. You can sanitize your goggles, but the N95 mask has to be disposed of.

Let's imagine you're a nurse at an ICU. You have two patients, as is customary for most ICUs. Every 15-20 mins you have to suit up, check your patient, unsuit, resuit, check other patient. Every 15-20 mins you are using two N95 masks. You do this 3-4 times per hour 24 hours a day. And you're just the nurse. You also have doctors, respiratory therapists, techs, and other people coming in and out of the room, all of whom will be disposing of an N95 mask.
This makes me feel gross. I know what they're doing is totally legal, but it just feels wrong in this circumstance.

A business that was going to fail due to low margins without COVID19 shouldn't suddenly get to live because COVID19 destroyed the world economy.

It has to be a pause in collection (and interest), but at the end of the day the lender also has to get their money back.

I would wear an N95 mask sometimes in Asia, to mitigate the pollution. I didn't throw it away after each use. I imagine their use by medical professionals to be a much different case though.

I think a lot of Asian people wore the cheap cloth ones. I have learned recently that these sometimes have replaceable inserts inside them.
The article mentions this Florida company as one of the suppliers of such machines. They have a reasonably informative website.

According to OSHA

"Fit factor is a quantitative estimate of the fit of a
particular respirator to a specific individual, and typically estimates the ratio of the concentration of a
substance in ambient air to its concentration inside
the respirator when worn."

So I guess 100% would be like if the test aerosol had an ambient concentration of 100 µg/cubic meter, inside the mask the concentration would be < 1 µg/m3.

67% would be 33 µg/m3.

Doesn't seem like a fool proof mask but there is prelim evidence that the initial virus load has an effect on symptom severity. If you could cut exposure to 1/3 i suppose that is better than nothing.
Now you're picking winners and losers. These people get to work but those people can't. Bad situation.
so wait, is it OK to use masks now? last time I went out with a mask I got chewed out by a clerk. It was... deeply weird. (I mean, I understand the guy had probably had a hellish day and that probably had more to do with it than anything, and I apologized and did what I could to diffuse the situation. But it was deeply weird, 'cause normally the economic inequality here in the bay area means that I'm treated really well.)
Is personal charity to business owners really an effective way to help prevent a recession? What if you're supporting one of the weaker businesses that could barely survive anyway? Those are usefully killed off in a recession, improving overall efficiency. The more that close down, the better business will be for the survivors.
I like the thought of this idea, but it won’t work. If the business spends the money from the cards now then it will be on the hook for the meals later. It is basically just an interest-free loan to the business that will have to be paid back. The party that is really being bailed out here is the landlord.

A better approach would be to let the restaurant go under and have some way to pledge that you will support the new restaurant that opens when things return to normal.
I don't think it is sad. Attractive people are, by definition, attractive. They are nice to look at. This is not everything, but it isn't nothing. In the same way, some people have massive innate talent, or disposition, or intelligence. They can be fun to watch or listen to or just be around.

Perhaps it feels sad because much of attractiveness is "unearned". Some people are born more or less attractive than others and that is unfair - but I think most human attributes are like this. A smart person didn't earn their intelligence, and while they may feel they earned their knowledge, and perhaps they're right, they'd never have been able to earn their knowledge and intellectual accomplishments if they had been born mentally deficient. Famous basketball players work hard, but it wouldn't matter if they were born into 5'5" bodies, etc.

That some people are more attractive than others is unfair, but that fundamental unfairness shouldn't prevent us from appreciating attractive people in my view. I don't see anything wrong with promoting more attractive TikTok users provided it does actually result in a better user experience. In the same way I don't see anything wrong with selecting attractive people to be actors in your movie or film. If you want people to like the main character then it is probably smart to cast an attractive person.
Seems pretty similar to a tax break though no? I think UBI and taxes need to be intertwined. I could get behind UBI if coupled with a flat tax as a simpler system than progressive taxation (that has the same effect, but without all the loopholes).
There is quite is quite a bit of information readily available about sterilizing disposable N95 masks with UV-C light. While not nearly as good as a fresh mask, this might be a preferable alternative to reusing the same mask unsterilized.

TikTok is like Twitter in that you can follow people.

Something not trending on Twitter isn't the same as not existing or not showing to one's followers. Likewise, something not becoming a suggested TikTok isn't the same as not allowing the post wholesale.

Avoiding cache line overlap by replacing a 256-bit store with two 128-bit stores
Off the top of my head I would say open a Shopify store and find a module that creates a unique order code(Assuming Shopify doesn't do this already). From there build your products for different gift card amounts and then have people redeem the order in store. Most POS f&B systems I assume will let you keep a note for order customization's. In that field I would enter the order code after verifying that the order hasn't been marked delivered in Shopify.

The note keeping isn't super necessary but it can be helpful when trying to track down the order being given to a customer.

In this I'm also assuming Shopify lets you mark orders as pending, delivered, etc. I've only used competitors to it so I'm not 100% sure.

> The coronavirus is an upper respiratory virus

I thought it was a lower respiratory virus. I have no idea if that changes the efficacy of masks but...
https://www.health.com/condition/cold-flu-sinus/surgical-mas...

>“Yes, a surgical mask can help prevent the flu,” Sherif Mossad, MD, an infectious disease specialist at the Cleveland Clinic, tells Health. “Flu is carried in air droplets, so a mask would mechanically prevent the flu virus from reaching other people.” It would work both ways, says Dr. Mossad, preventing transmission of the flu virus to others and for keeping a mask-wearer from picking up an infection.
No country has the manufacturing base to meet the demand for these masks under a pandemic, not even China. That’s what the article is all about. Your thoughts on the merits of trade wars are not applicable.
> Have you lived in China for long periods of time?

I was born there. Have family there. Wife is Chinese.
Your math assumes you are the only person using masks and have daily exposure.

It breaks down when people are in isolation, which many of us now are. You are not out daily, so a 50% reduction is a 50% reduction, and with luck you never accumulate enough to get sick.

If everyone wore masks, then every ones daily exposure would drop dramatically. You get 50% less intake, and infected people are emitting much less too. You have pretty much eliminated air born transmission, and can now focus on hands and eyes.

A couple years back, I watched an osprey pull a three-foot length of steel wire out of a frayed cable on one of a tramp steamer's cranes.

Osprey nests are wild. From the outside they look incredibly messy, and the wire wasn't an aberration; the birds make considerable use of human detritus in their engineering (cf. https://i.imgur.com/R2nO1Zu.jpg), and while I've never seen the inside of a nest due to how high up they build, I gather the end result is quite deep and spacious.
When was this? Last week Trump said this was overblown; yesterday he said he was ringing alarm bells before anyone else. Seems like a lot of tunes have changed in just the last few days.

This comment sums it up: https://news.ycombinator.com/item?id=22611017
The virus is carried in tiny droplets in the air, usually from a cough or sneeze. Any mask that catches those helps prevent virus spread to and from you. So literally a bandana covering your face is going to prevent some. Of course it won't be as effective as a legit N95 or N99 mask, maybe it's only 10% as effective, but that is not the same as being totally ineffective.

Further, any form of masks provides a psychological aid to help people stop touching their face.
I don't think it's fair to criticize all governments (or forms of government) equally.

In our town (New Jersey, USA), several parents decided to keep their kids home from school as the virus spread nearby, even as the school stayed open. Evidently (https://www.nytimes.com/video/world/asia/100000006970549/cor...) in other forms of government, the government itself controls what information is available (and the ability of citizens to make prudential judgments).

That doesn't mean this virus is "China's fault." As you say, all governments demonstrated some form of incompetence (usually starting with the assumption it can't be that bad). There is here an interesting contrast in how two systems respond to incompetence. Since surely how we disseminate information is important to the response to the virus, it seems fair to point out how one system disproportionately impedes how that happens.
So, are condoms, they fail, can be worn improperly, etc... yet they are recommend over and over for safety reason....

Same with masks, they are not perfect, they could be miss-handled, yet they provide some degree of safety and are better than nothing.... otherwise why would health officials wear them at all?
"They were replaced by automation" is a vile anti-worker canard. The manufacturing jobs went to humans in China, not robots.
One of the turning points was to actually work backwards: instead of calculating every ray from a light source, then throwing away anything that doesn’t hit the camera, ray tracing now starts with the ray endpoints that end at the camera, thus saving all that work that needs to be thrown out the other way.
Reflections do need access to the geometry off-camera, but it’s accessible in some for or another by needing to be available when the player looks at it, as well as needing to exist for gameplay interaction (such as an enemy shooting from off-camera)
It's not the same result. Ugly/fat/poor people can make engaging content and that will be recommended on Instagram.

The content you see depends on your interests. Making this up: if you regularly engage with topics that have a majority of fat people posting, say weight loss strategies, you will see a lot of fat people in Instagram Explore.

It's the difference between:

- Instagram: "I mostly see beautiful people" (because that's the content I and many users engage with).

- Tiktok: "I never see ugly people" (because the platform has a guideline that prevents that content from being shown to me)
