These folks [1] are working on an open Covid-19 test. There is a pretty significant logistical train that I haven't seen systematically addressed yet in the project, though lots of those pieces have open projects that can be picked up, adapted and integrated. Even failing will be valuable: that identifies gaps to address.

Option<T> is conceptually easier because:

1) It applies exactly the same way to any type, not just char.

2) You don't need to read the man page for every single function that returns an int on the off chance that said int actually contains a bool, a char, or a short plus additional flags.
At least some N95 respirators have small amounts of zinc and copper for this reason.

You are making a perfectly reasonable argument, yes. :)
cross platform mostly works.
>No. There are instances of people testing negative and then testing positive again, but the strong consensus is that this probably results from faulty testing and/or changes in how viral material manifests at different stages in a person's infection. The chance is very small that people are truly getting re-infected.

This is also why testing everyone and anyone is a bad idea. Half or more of positive tests of people without symptoms being tested because they are in close contact with infected seem to be false positives. https://www.ncbi.nlm.nih.gov/pubmed/32133832 I've seen something else I can't find at the moment that says that only about 10% of those with both potential COVID19 symptoms and a contact history indicative of possible contact are positive. It's both pointless and dangerous to have someone get a false positive reading, perhaps do self-quarantine for 14 days, then go out and promptly get (not re)infected.

The US government (and I think UK too) is getting a lot of criticism for restricting testing to those who meet the requirements of symptoms and contact history, but it's almost certainly because the CDC is aware of this. The Canadian government, too; Prime Minister Trudeau is not being tested, although his wife is positive, because he is asymptomatic. https://www.usatoday.com/story/news/world/2020/03/12/sophie-...
The whole world benefits from these things. The rewards far outweigh the risks.
Why Do Raindrops Make Bubbles?
People don't need numbers any more. It's only going to matter to some people if someone they view as a 'healthy, normal' person tests positive. Even more of a freak-out if someone like that dies. If a famous celebrity or athlete gets were to die from this, it would set off a lot more worrying
Do you know of anything worth reading for CMake?

The official docs are too sparse to be useful to me and the results of googling mostly give stale advice.

I also have being easing into CMake recently - I was initially impressed as getting a "hello world" example was simple and the CMakeLists.txt was clear. As the project has progressed - simple additions like unit tests, external dependencies, specific aspects for debug builds, handling basic cross platform differences, etc. have made the CMakeLists.txt almost unreadable and really quite brittle.

I'm not quite at the stage of abandoning it but I have wondered whether an old fashioned Makefile wouldn't be simpler. At least there is a logic, if convoluted, to make and the documentation is top class. CMake seems to lack a clear design and just seems like hack on hack but this could be my ignorance.

I've no real idea of what I'm dealing with when working with CMake - it's wears declarative clothing but actually it isn't at all. The ordering of CMakeLists.txt is significant and you have to be aware of whether what you add will be "executed" during cmake or gets executed with cmake --build.
Good point. the only reason i list discord as a contact is because my platform doesn't offer private messages yet.

For anything that doesn't need to be private you can simply ask around on the public chat on the platform :)

I thought the same thing and it must be that when you have a family, you can go through tp pretty quickly. Roughly four times as fast for two adults and two kids, and twice as fast if you live with your partner, compared to just living alone.

I think this is similar to what everybody else is doing -- using a thermocycler to run PCR. It can run 96 samples in parallel and takes 3-4 hours to run through 30-40 cycles. But there are a lot of manual steps, and I'm not sure how much the SK company automates them.

This article does explicitly discuss pre-symptomatic transmission, specifically it being worse than SARS but better than flu in that regard.

I'd love to see some. I looked quite hard into two topics, gravity models of trade and the Philips curve, and I never found much I thought was convincing.

I think the culture of academic macro doesn't appreciate just how hard it is to thoroughly test a model. It's not as simple as writing down some dynamics, estimating via maximum likelihood, and drawing conclusions based on the parameters that pop out.
>If you're not bothered reading about the topic being posted, why are you weighing in on it?

This appears to be an issue for what seems like well more than half of all HN comments. It's common on reddit, too, but seems more common here, for some reason. So many people just respond to the HN title and don't click the link.

>People who post their dirty laundry on an app in a time when we know everything online is recorded, tracked, sold off to others, hacked and stolen or archived in a government database and then have the gall to complain about that dirty laundry getting out should have their internet access removed from them. Parents who let their children put themselves in this situation should be monitored by CPS.

This is completely absurd. People expect public social media information to be public and anonymous secret-sharing app information to be anonymous and private. And the information does seem to have been treated as private by the company, with the issue being this unintentionally exposed database.

There was no agreement they signed saying their secrets weren't actually secret. They were under the impression this information wasn't public. The company is 100% at fault and users are 0% at fault.

Parents also shouldn't be responsible for every single thing their children say to their friends and classmates. You think parents should be monitored by CPS if they don't tyrannically ensure their children aren't using any sort of messaging apps? That's insane. Education around potential security issues with services is important, but the fault here is still entirely on MediaLab.

They don't "have the gall" to complain; it's people like you who have the gall to blame customers for entrusting private information to an application designed for private information. Blaming victims and parents and saying they should be blocked from using the internet, or having kids, is one of the worst takes I've ever heard.

And there are plenty of things that are (almost certainly) not in fact recorded, tracked, sold, hacked, or archived by governments. If you just want to give up on anything on the internet possibly being usable or trustworthy whatsoever, why are you still using it? You should be removing your own access to it.
This can't be the only option for testing. Korea has tested hundreds of thousands of people so far. By far the largest number of any country, including China. Such high throughput does not seem achievable with these machines unless you already have a ton of them, and all the reagents are stockpiled.

https://www.worldometers.info/coronavirus/covid-19-testing/

Everyone else seems fairly low throughput, with the US being on the "ridiculously low" end of that spectrum if you consider tests per million of population.

I wasn't making any claim about the actual causes... I was simply stating that the statistical effect you see can be completely explained by random variance, so you can't use the result as an argument for a cause. You have to search elsewhere for that evidence.

It's almost entirely teenagers who don't know better. The parents don't even know about it. And if they do, they don't know any better either.

The problem here is not people. The problem is this bit:

There is a question I usually ask when I meet new colleagues and want to get to know them better: “If you had a crystal ball and it could answer a single question about the future, the past or the present. What would you ask?”

The most exciting answer I got so far was: “I would ask it to show me life on a another planet.” So cool to imagine...
The kind of batteries that we're talking about simply do not operate outside of the 0-35 degree Celsius temperature range. It will never be "ICE to charge batteries" because the batteries will not cycle in those conditions. North of 16C is optimal. The limitation is the chemistry.

If you look at the temperature variance across the planet, you'll realize that there's vast numbers of people for whom batteries are never going to be an option.
Hmm, not your typical RADAR. This is basically using the RF emissions of the plane, and their detection at multiple RF detection stations with synchronized clocks, to determine the difference in arrival time. The radio emissions all travel at the same speed through the air, the difference in arrival time can be used with some simple trig to figure out where the RF emitter is. There are a number of Time Difference of Arrival or TDOA systems out there. It is why I expect aircraft stop using their radios when they are about to engage their targets.

That said, they are "easy" to jam in the sense that when you have two radio signals on the same frequency, they will interfere with direction finding. And there is a lot of noise in the RF spectrum out there, especially during thunderstorms.
I'm a daily reader of Matt Levine for probably four years now and I have to admit I've come to precisely the opposite conclusion about how he writes. He points out quirky situations that may appear superficially stupid, but in reality are somewhat justified given the way the system exists. And he does a superb job in pointing out the humor of these situations while still breaking them down to show why things are not as simple as they seem.
> was literally insulted on YouTube when I advised to keep water in your mouth while cutting onions to avoid crying

The reaction is unsurprising. Anyone who has ever cut onions gained an understanding that irritating gas (http://enwp.org/Syn-Propanethial-S-oxide) wafts up into the eyes. The hypothesis that water in the mouth is supposed to help runs counter to intuition.

It affords testing. Devise an experiment and let us know the result.
I think we (UK) are trying to be too cute about managing the curve, like we can ramp it up to the capacity line then slam on the brakes with the big measures at exactly the right time and keep it ticking along there nicely through the spring and summer and have this thing wrapped up by the end of the year. It could all go very badly wrong.

I get the impression we're being overly influenced by a few gurus of behavioral science, a field which must surely make even experimental psychology look replicationally robust, and in particular by 'nudge theory', for which our politicians have a particular penchant. I also gather we war-gamed this exact scenario two years ago, which may have led to a degree of overconfidence amongst some key players.
> All of which have tiny populations compared to the UK.

Is 66 million really that qualitatively different than 24 million?
> Drop them on a military base

If you can get close enough to drop a bunch of slow drones, you can get close enough to just drop a bomb on the whole thing instead. Much more bang for your buck.

Let's also not forget that small drones might become 'banned' much like chemical weapons did, if they ever became viable.

I can pass parked cars in relative comfort, but stopped buses are way beyond my risk tolerance, and those are ~80% of the bike lane obstructions I meet in SF. Why bother cycling if you’re going to be limited to the bus’s schedule anyway?

8500 is still pretty high for a turbo. most performance cars with turbos don't have a redline that high.
One of my colleagues has been infected, it's another department, so we aren't doing home office yet, but if just one of the people I came in direct contact with was also infected, I have to stay at home for two weeks. I get grounded for 2 weeks, I can't even go outside to buy food. That's a real possibility for me.

No, the world isn't going to end for 2 weeks, but I might run out of food during that time. And I don't want that.

People think it cannot affect them until it does.

Spanish Flu mutated into a far deadlier version over time because it spread faster in hospitals and troop transports than on the streets. We may see a similar situation with corona virus if the quarantines and social distancing are too effective. Ideally, we want most cases to be transmitted from the weak cold-like corona virus cases, not the lung-infesting killer cases.

Seems like the best solution is to take the markets away for these sellers to price gouge, which is what's happening.. and introduce punishments for anyone who tries to get around these measures.
To the extent that car owners are subsidizing the trucking industry, and to the extent that trucking industry subsidies flow through to the cost of goods delivered by trucks (the same thing as saying that increased trucking costs flow through to goods delivered by truck), then shifting the balance necessarily means car owners paying less and non-car owners paying more.

I will admit I stumbled upon this conclusion and felt it was ironically juicy and a bit provocative, but it seems like pretty solid macroeconomics to me!
I don't think "hoarding" is the right term to describe this behavior. "Profiteering", "scalping", "gouging", etc.
This strategy is not insane only if there is also a concerted effort to protect those who are vulnerable while the virus spreads. The problem is there isn't one. At all. None. Zip. Zero. Some care homes are, off their own back, banning visitors but apart from that the old and the vulnerable are not being asked to self isolate or engage in social distancing, only those who have symptoms themselves are being told to self isolate, and not members of their households. Social clubs, churches, pubs, cafes, day centres, restaurants etc. where a lot of older people congregate are all still open. None essential home visits have not been curtailed and people are not being advised to socially distance themselves from the vulnerable.
I found the pictures in this article so interesting I struggled to read it. It’s just too bad they didn’t really tie into the topic well. One would have been enough, but they stole the show.
> I honestly don't get the attitude against a certain level of preparedness. What is wrong with stocking more non-perishable food stuffs at home if those are the things you'd normally buy anyway? You don't need to fill your basements with MREs, just get more of the usual non-perishables than you'd normally do - pasta, wheat flour, oats, etc. Get some yeast to bake bread as well while you're at it. Get butter, put it in the freezer. Dried beans last forever - I had some around which I took with me when I moved from the Netherlands to Sweden about 20 years ago, made a chilli with them, tasted 'like new' - and can make a good meal with a few odds and ends. Get 'canned' (i.e. packaged) tomatoes, frozen vegetables (the power will stay on during this crisis), etc. This is not doomsday prepping, it is common sense.

I have no problem with this, but that's clearly not what GP is advocating for. I doubt most in this thread even comprehend how much food is required for a 30 day supply of your average household. Buying double the amount of perishables doesn't seem unreasonable, stocking up for a month+ is absurd.
Having this with rust could be a very powerful combo.
I saw a teacher somewhere say that he had noticed that kids increasingly have trouble understanding how file paths work in computers. It's something I think is very intuitive and key to use a computer, but I guess when you're only used to smartphones you rarely if ever have to think about files and folders.

This is exactly why the Raspberry Pi was created, to enable kids to get computer experience in a world full of locked down phones and tablets.
> How do you mean combustion being CO2 neutral?

I read elsewhere that they can run the engine on a wide range of fuels, so I think they mean it's CO2-neutral if you run on biofuels.

I'm not a big fan of biofuels, but I think they can have some role in a transition period if you have a mostly battery-electric drivetrain with an engine as range extender... and this car is a pretty good model for that. Remember that the production of batteries is limited, so it might be better to build 2 million cars that use a range extender once in a while, rather than 1 million cars that runs only on batteries (I say this as someone owning a pure battery electric vehicle btw).

But I think the key for this kind of transition vehicle is an ultra-simple and compact generator. Maybe something that is modular and can be swapped with a battery pack later. I think free-piston engines is what we need (I'm guessing they need something like Freevalve though, so maybe Koenigsegg's research contributes there)

Exactly. We have huge debts and our "economy" runs on the assumption that, if very little goes wrong, we might be able to stay afloat.

The time for creating choice on the cornonavirus response was during the last 20 years. They chose rampant financialisation, leveraging future income.

The UK has no energy security. No food security. I feel the corner we have painted ourselves into makes a prolonged shutdown far, far harder.

It's also assumed that anyone not using the "low barrier to entry" platforms is a professional (or else, trying to make a professional product), which, ironically, raises the barrier to entry for anyone trying to get out of the sandbox.

I'm not sure I understand how this herd immunity strategy can work in the current world. Albeit the UK is segregated from the rest with water, there are still a lot of people entering your frontiers and that are not immune.
Unfortunately even if you're starting a new project chances are that your dependencies are using cmake and they expect their dependencies to use cmake... in the end of the day you spend a lot of time fixing the upstream projects build files.

More than that CMake at this point is the ""standard"" and there are many others with a similar share of the market and selling points, it makes it harder to pick one that is not CMake.
The economy wasn't important for Brexit but it somehow is for COVID-19, and we're going to sacrifice half a million people (best case).

Why Large Organizations Trust Kubernetes
In an episode of Curb Your Enthusiasm, the protagonist has to find the total weight of all the passengers for an airplane, but every passenger is uncomfortable sharing their weight. To me this seems like a problem that could be solved cryptographically, as it seems reminiscent of the SMP or distributed key generation. Does anyone from the crypto community know if there exists a solution for a problem like that?
Hello auskje, maybe my post was not clear. The phone acts as a connecting point to the drone, through a manufacurer's SDK.

The camera of the phone is not used nor is the phone flying. Actually the phone is connected to a remote control. See [1].

The role of the phone is not only as a viewer of the live video being captured by the drone, but also as a 4G internet point and a hardware video encoder, that pumps the live video to my platform.

I had the same discussion a few days ago and someone posted https://www.businessinsider.com/wuhan-coronavirus-risk-of-re... [It has a link to a video, but the caption of the video is wrong. The recommendation to the cured patients is not to increasing their physical activity but to enhance their own health safeguards.]

I found two other articles about the same case https://globalnews.ca/news/6623287/coronavirus-multiple-infe... and https://www.reuters.com/article/us-china-health-japan/japane... . t's not 100% clear, but it looks like a continuation of the first infection after a few week of no symptoms. It makes more sense than no immunity (at least at the short time), and a second independent infection.
