A good heart rate sensor - If you're getting into REM you should see your heart rate decrease, if not then you're likely not getting the benefits of proper sleep.

I wake up a lot in my sleep, so generally I have been looking to reduce my average sleeping heart rate through exercise, diet, sleeping positions, etc - which has been quite successful. if you chose this route, remember to change one thing at a time and leave enough time to measure the difference.

Another thing that could work is simply having a motion-detection camera. The more time the camera spends active, the more you moved that night.
Most companies aren’t fully remote, so dogfooding the common use of Slack seems smart, where it is still a useful tool even if you are slacking someone 5 feet away.

It also leads to nullifying the advantages of the cloud. The whole point are the proprietary services they offer, and use those instead of building them yourself. Trying to be „cloud agnostic“ is one of the biggest mistakes one could make.
Yup. Two days ago I received an email from someone asking to advertise hxxp://www.masktouch[.]com/ on our site. Compare the masks on there to the masks on the site posted here--they're nearly identical. Compare the source code--same style, similar comments. Even the red buttons on the sites are similar.

I went through all the "certification" docs on both sites. I found nothing that actually certified either of them for anything. Anything that would've been remotely meaningful was censored (blurred).

If I'm making incorrect assumptions based on circumstantial evidence, what choice do I have? There's nothing on these sites substantiating their claims. If this is legitimate, you need to publish a complete paper trail that readers here can verify.

Edit: To clarify: Calling it a "scam" might be a bit harsh, but it's definitely misleading. There's nothing special about these tests, and there's a reason they're cheap and not in widespread use--they're not going to do what most people expect. This post sums it up nicely: https://news.ycombinator.com/item?id=22642421 All these sites are probably just dropshipping the same items from the same factories at heavy markups.
DJI Won the Drone Wars, and Now It’s Paying the Price

Taiwan rapidly built up factories to make 10 million masks a day for its citizens (population: <24 million) as part of its plan.

Masks for everyone in public is a necessary but not sufficient condition. Check out Taiwan's Covid-19 Response Plan published in JAMA for details:

https://jamanetwork.com/journals/jama/fullarticle/2762689?gu...

What is the cost of an automated mask making machine?
< $100,000/set (based on Alibaba data). Each set can make ~100 pieces/min * 60 min * 17 hours > 100,000 / day.

To make a mask daily for everyone in the US would take 3,300 such machines * $0.1 million = $330 million.

Along with all other costs, total capital investment is likely less than a few billion dollars. Costs of capital, materials, operations, and distribution all together would be negligible relative to savings in healthcare, not to mention less misery all around.
While you’re obviously entitled to your opinion, many, many people disagree with you.
This whole argument is frustrating and annoying to me. I know that we're obsessed with "data" and "increase the sample size" on this website, but those things take a lot of time. And, given that my parents are old and have at least one factor that make them "high risk", I've started to reevaluate my priors on constantly insisting on more and more data before I make a decision.

Taiwan, Japan, Singapore, Hong Kong ... they all wear masks to some extent, normally in non-pandemic periods. They now do it at scale. They're at the bottom of the barrel in cases today (Russia is too and I don't really understand why unless they're lying). So, perhaps we should just start wearing masks. It costs nothing, assuming it's possible to get them, though for whatever reason our smartest people - both in the actual elite and here on HN - exclaimed that wearing a mask "does nothing". And one of the results of everyone telling us back in January and February that "masks do nothing" is that we're now 2 months behind procuring a cheap item that could actually do a lot of good. What a damn shame.

Twitter's value proposition is it's community now by far, not the character limit gimmick.

Sanders proposes a wealth tax as well. Not knowing that, coupled with ludicrous fears about him “seizing the means of production”, strongly indicates a questionable origin for your impression of Sanders.

The same thing goes for governments that he’s praised, a completely manufactured controversy. It is not condoning authoritarianism to say, for example, that China outperforms the US in infrastructure. People get hysterical about insufficient condemnation of the Cuban regime; I wonder how many are even aware of the murderous right-wing military dictatorship that the US installed and the communists replaced. It’s a very similar situation with respect to Nicaragua. Somehow the outrage about authoritarianism is missing as long as the US is directly profiting from the oppression. See Saudi Arabia vs Iran.

>Internally, things could be rather mundane

Elite developers often make things mundane. No fires. No explosions. etc.
I think that wearing a mask is good but it is not the silver bullet. Actually any form of physical barrier to stop the transmission will help, including social distancing (God! I hate that phrase but everyone knows what that means).

It is like software development, preventing the cause is much less impacting to our lives than debugging the cause.
I'm on rural wireless broadband about an hour outside of SF. While the service has never been amazing (3Mbit on a good day, 10Mbit at best), it's been sub-1Mbit (and sometimes sub-0.1Mbit) for quite some number of days now. The rural wireless ISPs are swamped.

Holding duration.
Except now there is a serious social stigma against wearing masks. You are seen as taking what rightfully belongs to the hospitals and using it for your own selfish ends.
> our smartest people - both in the actual elite and here on HN - exclaimed that wearing a mask "does nothing".

I'm fairly convinced that the messaging behind the "masks don't do anything" rhetoric is to prevent a shortage to people who need them. Yeah, everyone wearing masks would probably effectively slow the virus but if there's known supply chain issues and everyone stocking up would cause availability issues for doctors & nurses, then we have to take the lesser evil.
Yeah, that's an interesting point as well. Our product is for gamers, who are usually "remote" (if you can call it that), but Slack may trend towards over-fitting to highly-engaged, fully remote work if they were to do this.

Yeah, but if everyone started wearing masks back in early February in New York City there wouldn't be overloaded hospitals in Queens today on March 25th, now would there.
Try selling them anything.
The split of "they don't do anything" and "hospitals need them" made no sense to Americans so they ignored both messages.
Does it really matter if it's N95 or would a bandana work? It would make it harder for a cough to spread from you, for sure. And it would remind you not to touch your face and keep droplets away from your nose.

Maybe the message should be: healthcare workers get the real masks, but the public still needs a covering (bandana or whatever)?
That sounds like a good reason to wear an obviously homemade mask?

No. My default behavior with Amazon is to add things I might want, or sometimes even need, but that aren't strictly necessary, to the cart and then decide on them the next time I find myself in the cart with a purchase that actually needs to be made.

The way this really plays out is my wife says, "Do you want this stuff in the cart?" and then I go and remove most of it.

Yeah but the effect is a diminished trust in experts. Which is why noble lies are toxic. Like, nobody who said that masks can't help has grounds to complain about accusations of "fake news" ever again.

My experiences with liberals while living on the west coast (in the US) was that the general idea of warning a person against somebody else was that people tend to disregard such warnings, and they prefer to see first hand how a person is before dealing with them (even in the extreme case of someone being a known rapist). Is that different in Canada, or do mainstream talking heads on TV take precedence over that convention?

> Everything I have read about or by Ezra Levant has solidified the idea that he is yet another alt-right media personality wannabe who LARPs as a journalist and sues anyone who disagrees with him.

Are you saying that this makes it okay? That's the sentiment the government seems to be relying on in this case, and if that's what you believe, then you're part of the problem.
If we don't take some sort of action to bring essential manufacturing, including pharmaceuticals, back to the US after this, I might entirely lose my mind.

It shouldn't matter where you fall on the political spectrum, or if it's going to cost too much for the labor, or the fact that the whole thing has to be powered by reverse carbon collection or whatever the hell, it just HAS to be done.
Like many others, I started off skeptical about masks due to public health messaging and all the general caveats about how hard it is to wear a respirator correctly. That’s no longer the case.

Wearing a mask of any sort reduces the risk of infection. That’s why hospitals need PPE and are even resorting to using lower-grade protection (e.g surgical masks instead of n95) due to lack of supplies. CDC is even recommending scarves as a last resort. They’re also reusing masks and wearing them for longer than they should. These are all signs that _any_ mask can provide some benefit.

Furthermore, it’s been well cited that wearing masks does more to protect others from the wearer than vice versa. Given that its possible to be an asymptomatic carrier, you should wear a mask to avoid spreading the virus unknowingly.

Obviously, full PPE should go to healthcare and other critical needs right now due to shortage. That doesn’t mean the rest of us shouldn’t wear masks, just that we shouldn’t selfishly hoard a bunch of n95s. I’ll bet lots of Californians have leftover masks from the wildfires that they could use.

My take is that reserving proper PPE for health workers until the crisis peaks is critical. But westerners don’t have a mask-wearing culture like Asian countries, and are more likely to have an all or nothing approach to wearing one (n95 or bust!). So the safest public health messaging is to discourage all mask wearing. Not sure that’s worked.
Can't find the article now but there was two fast tests that got forbidden in Sweden yesterday because they miss a large percentage of the cases making it meaningless in best case or dangerous to others in worst case.

In Norway if you have symptoms but not been tested you are allowed in the shops and work again one day after symptoms subside as "the chance of infecting someone drops drastically at the end of the infection" [1].

If you have a positive test you still have to stay in for seven days but they don't tell you why since the argument for the non-tested should also apply to the ones with a positive test.

However there is no hard data here but I think these anti-body tests are better for statistics than prevention. Maybe you could even get a "corona passport" so that when you have had it and become immune you have more freedom.

I'd use this over cgit. For exposing a read-only view of my repo on a barebones server. This does not include issues, pull-requests etc. and that is useful in some scenarios.
I’ve never stopped wondering if “masks don’t help” messages were given to the public because there aren’t enough masks for the health care workers (and others in helping jobs). I really hope not, because if that turns out to be deliberately misleading messaging, the short term benefit may very well be outweighed by serious long term trust deterioration in public officials, beyond what’s already there.
My sister, a practicing MD, says that cloth masks are worse than nothing because they act as disease reservoirs. N95 masks are single-use. People aren't throwing their homemade masks after every trip outdoors, so any contamination their masks "stopped" is just waiting for the next use to infect the wearer. (She cited a study she'd read, which I can't find, but this Wirecutter article [1] makes a similar argument in the first answer).

That said, that doesn't mean that masks aren't helping in Czechia--they're a potent reminder to everyone to keep their distance, and that their friends and neighbors have bought into the seriousness of the threat. That alone is worth something.

The solution could be to give that option to users; a way to mark a website or app as trusted or not. Apple's approach on the other hand really sets the web apps back, which I (as a privacy concious individual) am more comfortable using compared to apps.

If this encourages more apps to go the native route, we've done more harm than good. Apps can gather a lot more data than websites, such as the dreaded contact list access.
