HCoV-19 Strains and What Does This Mean?
https://nextstrain.org/ncov

I came across this strains chart and was wondering what they effectively mean. Is the virus significantly different, is it like flu and will have many versions? They listed no amino acid mutations towards top of detail, is this a key detail?
Not necessarily. If the primary vector is respiration but the reception can be through mucous membranes, then a mask that doesn’t cover the eyes (or doesn’t protect hands which later rub your eyes), then a mask would be more effective on those infected than it would be for those not infected.

Defining jobs as "bullshit" requires imagining you can design large chunks of society from scratch. Sometimes you can, but more often you end up with a system as complicated at the current system.

In utopia, we wouldn't need any lawyers. But we have lawyers now because we have disputes. Utopian planners always skip to the part where all the disputes are magically settled, or invent a mechanism only tested within their own minds. They leave the messy work of actually making working systems to the rest of us.
^This (which is the same thing both the original article and the RHS article said). Grass will out compete wild flowers if the fertility of the soil is too high. Either:

- get rid of the grass

- mow it very short

and then plant wild flowers. Just throwing seeds onto the lawn will do nothing.

To get rid of grass either:

- dig it out (easy in the right soil; very hard in clay which is a lot of the UK)

- cover it with cardboard, cover the cardboard with soil, and plant on top.

I'm currently converting our front lawn to wild flowers. Luckily we don't have clay so I'm able to dig out the grass.
How big of an area do you need to see this effect? I've never heard of this kind of pricing difference on a city, county, or state basis.

And the stock market varies wildly on a daily and monthly basis without affecting the prices of almost anything.

It seems clear to me that money is not even close to affected by consumer confidence the way the stock market is.
The acceptable solution is for society to adapt. That includes everyone accepting their lives will change, and rich people in particular accepting they'll be poorer for a while. And if we have to move to a war footing to stop people dying, then that's what we have to do. To say 'it's either continue as close to normal or people will die' is a false dichotomy.

Also: there's this 'oh well' attitude afoot here in the UK that we can't enforce curfews etc. because the people won't have it. To this I say: we lock people up here for hurty words on the Internet. The only reason it can't happen is because some people in power don't want it to happen.
And I definitely don't owe David Graeber better. He is a public menace who actively removes understanding from the world.

Creator of the site here. As recently reformed long-time mask denier who lives in Hong Kong, I wanted to get the word out to people in the rest of the world that wearing a mask in public is not only okay but likely helpful in reducing or slowing transmission of SARS-CoV-19.

My main motivation for this weekend project was the challenge I’ve had convincing family and friends in the USA to change their behavior over the past month in preparation for this virus.

Probably, because the US wars on behalf of Israel.

How I wrote the fastest directory crawler ever
Lots of open source is paid for, or at least the developers have real jobs as developers, and therefore they shouldn't be called amateurs.
Another "paper and pen" cipher that was published a few years ago is ElsieFour (a modified version of RC4)[1].

One of the nice things is that it even offers a form of authenticated encryption, though it is a very string-and-staples approach. The idea is that you would append every message with some secret text that the recipient would know to look for (if the ciphertext is modified with ElsieFour/RC4 all subsequent characters become garbage). In theory you would include the hash of the plaintext but humans aren't great at computing hash algorithms in their head.

Obviously these kinds of ciphers have lots of serious problems (awful timing attacks for instance :P) but I think they are a key example we can point to when arguing that banning (or restricting) encryption software is a fruitless measure to stop "the bad guys" from using encryption.

The essence of this article might not be hugely surprising to anyone, but it's still good that they did all the FoI requests and everything.
This ignores several things. For one thing we might get a reprieve due to seasonality. For another, better treatments will almost certainly be found in the near future. Some are undergoing trials as we speak. Then there's the issue of people who will acquire immunity and therefore cease to be transmission vectors. And then there's the most glaring issue: less than 6K people are likely to die in the _very epicenter_ of the epidemic: in China. Out of 55M people in that region. People are returning to work there now. So this can be contained, with drastic measures. And you can bet drastic measures will be taken if we even begin to approach seven figure casualty counts. Extrapolated from 55M Hubei population to 331M of US population, this would be less than 40K dead: on the order of a severe flu season, but compressed into 3 months. That's in the absence of any advanced treatments, and with a healthcare system arguably inferior to what you'd find in the West.
I've heard so many times from sources that I've thought to be reputable that the simple kind of face mask don't provide any proven protection. Not sure what to believe in.
You’d think that if the west gets the concept of condoms this wouldn’t be that far fetched...
For another example of doing this, see this one from a couple of years back:

Most butterflies will mate, make territories and remain in the flowered area. As they have yet all that they want, the need to move on and cross the road will decrease. Many butterflies will lay in weeds also so the area is safe for they for most of this live cycle. And in winter they simply will migrate. Is much better than the other option, safer for bikers and cheaper for the government.
It's hard, but I don't think it's impossible. Layers of bullshit accrue, much like layers of bloat. We could do more to combat the incentive structures that lead to those layers.

For instance, European countries have lawyers too, but they're not used or involved anywhere near as much as in the US. Societies there run fine without lawsuits as the default method of conflict resolution.

As I understand it, (not an expert myself)

- Sars-1 and Sars-2 (COVID-19) are related enough to bear the same name, thus having researched a virus for the former would be incredibly informating to finding a virus for the latter.

- As it stands, we know so little in that regard that we do not know if there is a possible vaccine for COVID-19. If I take an average between 3-10 years (the range of guesstimates floating around in some circles apparently), that's 2026-7 to have a definitive answer on that (it also depends a lot on the behavior of the virus, and we are only 10 weeks into this mess, we just don't know).

- human testing on Sars-1 may have been impossible or rather unethical, but models on animal species are just about the way we do it for everything all the time, so having a 15-year body of research + associated datasets would have been the reasonable, cautious thing to do. Having a vaccine for e.g. mice on Sars-1 available now would help a lot.

- There is no valid reason to have stopped Sars-1 vaccine research, especially given the fact that numerous experts were certain that new coronaviruses would cross again to the human race in the future (this is still true today).

- Because of all this, we are now forced to rush tests on "best guesses" for vaccines, with nowhere near enough data to make a really "educated" guess, far from the usual. Meaning, increased risk to the patients in those trials, but most dramatically for all: we have cornered ourselves into making moonshots in a hurry in the quest for a vaccine.

There is a possibility that we've gotten so good at molecular biology and modelling that we'll actually overcome these obstacles that we've created for ourselves, but the gist is that had we been a little more forward-thinking (including hoarding stocks for medical supplies, etc), the ultimate death count could have been orders of magnitude smaller, possibly anecdotal.
No, no, please no. Practically every health agency in the world is trying to discourage the general public from stockpiling masks right now. They will not prevent you from contracting COVID-19. They will prevent people who actually need masks from being able to acquire them.

The rest of the advice on this page is good. The premise that everyone should wear a mask is not good. It is harmful.

If masks contain spread and everyone wore one, it would lead to less cases.

The problem is that there are not enough masks to go around. But if there were, i would recommend everyone wears them. Just so it would make it socially acceptable to wear one if you are sick.

The compiler doesn't know it is doing unexpected things. The compiler is doing what's expected given the axioms it has to work with. It would be nice if the compiler added assertions in place to validate that the axioms hold, but that would often be very expensive. Recently I have been using the sanitizers extensively and has been a huge improvement, but of course they are too expensive to leave on in prod. Would be nice if a cheaper, although less exhaustive version were available.

Labs go quiet as researchers brace for long-term coronavirus disruptions
I think the easy answer here is that there’s no culture of wearing masks in public and it’s very visible and easy to ridicule.

This isn’t Tokyo, where everyone was wearing masks before this crisis and you get one for 400 yen at any convenience store, even inside the rail station.

Authorities in a democracy work mainly by persuasion, and they have a limited budget of how much they can educate and bend people’s behavior. This is what you would expect a system that takes citizen feedback into account, where citizens have a very strong prior that is inappropriate to the current situation.

Note most people in a democracy are strongly against government propaganda, but propaganda is basically state-owned tax on citizens’ attention. Think about how much attention it would take to educate people until they all voluntarily wore masks, whether that education would be politically popular, and also how many dollars in ad revenue that would have cost in the private attention market (ads).
Some of these exact techniques, but far more in-depth, have been used to track down and locate child predators who have uploaded images to the internet.

Science is one of the essentials. Music and art can and should be done remotely. Pets are fine but if you need pretty vest for your dog this season you might make it yourself instead of paying amazon to force people to crowd by hundreds over sawing machines.

The standard just declares an interface, to be added to a C library (maybe?). It's not the job of the compiler to check for programmer's faults. The compiler doesn't care and it shouldn't.
Ask HN: Dataset version control for ML / data science?
To data scientists, machine learning engineers and data engineers -- how do you manage your datasets? What tools and workflows, if any, do you use to version your data alongside your code?

Currently, my workflow for data analyses / modelling is essentially:

1. Write SQL query for desired dataset

2. Run query to produce CSV

3. Hash the file as an identifier

4. Upload the file to S3

5. Reference the file in Jupyter notebook / scripts etc.

6. Return to step 1 or 2 (depending on if I'm updating a report, or creating a new experiment with new data).

I'm curious if people have experience using tools such as DVC [0] for managing experiments. Git LFS could be useful, but it seems to be aimed more at binary assets, not large datasets of many GBs.

Artificial scarcity of hospital beds due to certificates of need
I wish they would repeal this requirement. Also if they’d loosen up the regulations against doctors owning hospitals, you would have a lot more to serve the public during these kinds of outbreaks. With limited capacity our current system just turns away people during a spike in demand.

It's skill, but I would hardly call it professional. Anons on 4chan do regularly much more impressive stuff. The gas station in this case made it particularly easy, anyone with a bit of experience from stuff like geoguesser and similar quizzes can find it easily. That's why I too consider calling this a "case study" pretentious.
In Asia, where mask-wearing is common (part of the culture, nothing to do with COVID), sick people wear masks. It's very practical, and also a social signal that "I am ill". As a manager of a business in SE Asia, people coming in sick but wearing masks was awesome. The mask-wearing reduced their infectiousness (because the mask stops saliva-borne virus communication) and made it OK to come in to work if you're feeling well enough to work. It's socially acceptable to not shake a mask-wearer's hand or otherwise touch them. It's as much social signal as anything ("I might be infectious, I'm not going to be offended if you treat me as a walking virus bomb").

Part of the problem for the West is that we wear masks when we don't want to get sick. Masks don't really work for this (the rest of the mask-wearer still gets covered in virus). And if we're diagnosed sick, then we stop wearing masks. Again, that's not how the mask thing works, because this is when masks are most useful. Both as a social signal and practical way of reducing infectiousness.

To use masks effectively, we need to stop wearing them when we're scared, and start wearing them when we're infected. But I think the social change to do this will be difficult.
Yes we've already extracted all the value we could extract from them. Better get rid of the useless husks asap.
