The difficulty and the required run time vary a lot starting from problem 150 or so. This one seems particularly difficult (it's rated at 85% difficulty, which is also the highest I've managed to solve). The problem here is that the search space is not 10^10, but higher, since if you iterate over k you don't know which values of m or n need to be tested. For m=1 it's clear that you can just use Pythagorean triples, but for bigger values I don't know if there is a reliable procedure to generate solutions.
The fundamental problem is that the narrative of the current administration is that globalization and global co-operation has been bad for the United States and that this policy has resulted in the U.S. being taken advantage of.
However, the correct response to this pandemic would go against this narrative completely. It is a common foe faced by all nations, and is an ideal situation for being tackled through global co-operation!

The current administration is continuing to try to solve this problem without turning to global co-operation. If the vaccine is developed in Germany, or the UK or China, the U.S. would then need to license this technology, and it would reveal that the U.S does in fact need the world, and that global co-operation is, at the very least, needed in some situations. It would lose face. If on the other hand, the administration can claim "Look! We developed the vaccine here in the U.S. .. I told you we didn't need those other guys. We will take care of Americans first, and then we will help the others." then it would validate the "America first" narrative.
I disagree with your second conjecture. The polarization of United States has been largely due to bankcrupting its middle class of its industry, paying off executives(not literally, but due to allure of making cheaper goods in China), social media and Russian interference in the election of Trump.

This is a grand plan of Russia and China to divide western nations, increase internal anti-US propaganda to bolster their authoritarian regimes.

You're pointing to the symptoms, not root cause. And this is exactly what the communist regimes want the west to do - fight against each other. Just wait before Canada get's roped in all of this as well.

Ouch. Good luck trying to get the timing right.

The earlier you start with countermeasures, the longer you can try them and see how they affect the spread rate. If you wait to impose them at the last minute, you will have to choose erring on too expensive measures or on letting your people die.
To offer a little feedback: Focusing on an immediate deliverable that solves a finite problem was good, but I think the proposal was structured in such a way that it asked for too much commitment too fast.

A "hackathon" has a short time horizon. At the end of the hackathon you'd have some idea as to whether or not you'd want to continue, regardless of whether the goals of the hackathon had been achieved. Give people a chance to try out contributing in small amounts, and to evaluate whether they want to continue contributing.
> Why should a disease that is less bad in every conceivable way be so much more panic inducing?

Because it's worse in every way: the initial containment has failed, the base immunity does not exist, the transmission rate is much higher, and the virus is more deadly.
“Can prove”. “May not be liable”. Sounds like a hassle, and uncertain. Especially given the prevailing mob mentality against raising prices in an emergency.
Ask HN: Mark yourself infected in social media?
Are any of you planning on adding a feature to your product where you can mark yourself infected? Somewhat opposite of the facebook "mark yourself safe" feature?

I think the data would be tremendous. The obvious ones would be twitter/facebook but I think anyone that has a popular app that tracks your location could also benefit.

Part 2 of this question is what is currently available right now around this data that I could analyze currently?
It's also a great way to encourage people who may, for example, be skeptical of everything to take actions they otherwise wouldn't.

Think you just have the common cold and won't be doing any harm by going out like normal? Well... out of an abundance of caution, stay home anyway.

Your point is well taken that this is probably the least anybody could be doing, but nonetheless, the actual actions being taken and the end result seems to be positive, which is far more important than the language behind it, IMO.
This is very well phrased. I've been thinking similar thoughts, but it's hard to put them into words. Democracy and freedom of expression is fantastic, but this crisis reveals the failings of modern democracy in a spectacular fashion.

Especially in the places that have had the most spectacular demonstrations of this recently; the UK and the USA. It's tragic, but as you said, this is a mild wakeup call. Hope it's heeded, but I'm not too optimistic.
Did not know that, thanks. I searched for dc inside bc and could find a reference to /usr/bin/dc, so I think bc still is just a wrapper.

> According to a "parasite stress" hypothesis, authoritarian governments are more likely to emerge in regions characterized by a high prevalence of disease-causing pathogens

This predicts that governments will become more authoritarian during and in the aftermath of the pandemic. This is unsurprising given the widespread demand for large scale government interventions. Among the major damage Covid-19 leaves behind may be to give authoritarianism a better reputation.
EVERY country puts itself first. International cooperation happens either when they have capacity to spare, or when it is mutually beneficial. Your demonization of China based on its political system is based on stereotypes of what "evil communists/authoritarian states" are in theory, not on what they actually are in practice. China is not comparable to the Soviet Union.

Which words say things in China are still out of control, and why do you trust those words? I have family in China, if things are out of control instead of getting better, I would know it.

You say all of this right after China donated tons of medical equipment and medical teams to Iran and Italy.

I saw how things were in China during the early days of the lockdown, how both people and government cooperated. I will believe my own eyes.

Of course, no government is perfect. Mistakes will be made. And some people are corrupt. But none of that means that throwing the baby out with the bathwater -- being overly cynical and declaring all governments as evil -- is the right answer. Now is the time for both people and governments to learn about what cooperation and good governance is about.
> I don’t see much reason to give his voice any more weight

It is the US that is putting itself first in this case though. In addition to that i would claim that pretty much every single government right now is quite authoritarian.

Angela Merkel and many others. You have to know that we don't have the 1 guy is all principle.

A leader here is a communication channel after internal discussion in their party. If there's a rotten egg ( eg. Like in Hungary) the democratic system will adjust to filter him out after a while.

It's slower, yes. But it's less confusing and I think it's a good thing. No wild bull situations like in the US.

I would say that I very much liked Obama. A lot of charisma, he also notified the EU about some things but he did it with a sense of decenty. Which shows clear intellect and respect.
Just remember that parsing text files (big for me) is glacially slow in Powershell due to all the object mess. I enjoy most other things.
That is probably completely dependent on the infection you are treating. Sometimes it may be better to reduce stress on the patient, sometimes higher temperatures help stop the infection. After all, someone got a Nobel prize for infecting people with malaria to cure them of syphilis https://en.m.wikipedia.org/wiki/Pyrotherapy
China is a country with unconstrained capitalism. U.S. has constrained capitalism. Before you go down that rabbit-hole, please consider that capitalism is not a policy engine. It is a means of production, and in fact the only meaningful system of production left in whole world.

That doesn't make it good or evil. People are good and evil. The policies they apply can have good and evil effects. Capitalism can be employed to raise the poor out of poverty, or to keep them there. It can be used to effectively help the sick, or ignore them.

Constrained capitalism coupled with sensible policies, kind, honorable people to administer them, and communities with a sense of charity to share the benefits produce some of the best results the world has ever seen. But it is the quality of people in which we're lacking. Confiscation and coercion won't improve things, it always makes bad situations worse. We need administrators more interested in making the government work for the governed than for the governing. We've not had that for quite some time.
The story is outrageous. However, how many of you here on HN throw up a red flag when an article uses the word "poach" around scientists and engineers?

I'm permanently distrustful when I start to hear this word. I think this was a result of being an engineer in Silicon Valley from the late 90s through 2010 or so. The large Silicon Valley employers (the ones lobbying congress about a shortage of engineers) were clearly involved in an absolutely loathsome no-poach collusion to suppress wages.

This doesn't mean I automatically reject the possibility of bad faith when I read stories about "poaching". For example I do agree that USC crossed a line and acted reprehensibly when it "poached" UCSD's Alzheimer's research lab. But I still want to know how much the UCSD scientists were getting paid relative to the housing market nearby (in this case, La Jolla, CA). This info is almost never included in the articles (just like the press is willing to report about how a tech CEO is experiencing hiring difficulties without once mentioning the salary offered).

This article suggests something more akin to the USC/UCSD scenario, where it's more than merely hiring away talent. I'd just like a little more information about what they mean by "poached". What were the working conditions and salaries for the German scientists getting "poached"? Are these scientists superstars? You know what large law firms, investment banks, tech companies (post-collusion), and sports teams pay superstars to keep them from being "poached"?

The word "poached" implies that engineers and scientists, among others, are not truly free agents, but are owned in some way by their employers - and this worms its way into policy (for example, in how H1B visas are actually controlled by the employer, not bestowed directly onto the employee and/or would-be immigrant). I reject this.

UK Policy is a speculative lunacy.

Actually this is modeled quite well in "Plague Inc" (the game) if you mutate the virus towards being too lethal it will not spread fast enough to annihilate the entire population.
To put a positive light on this disturbing news, I, like many here, am deeply grateful to the scientists and engineers (including at CureVac) working tirelessly around the clock and around the world to help develop a vaccine, save millions of lives, and let us all return to normal life.

I'm sick with something viral at the moment, and I hope to do my part by social distancing, disinfecting public surfaces I'm touching, and working pretty much exclusively from home. Flatten the curve, and let those who truly need it take the ICU beds and hospital spaces. One way or another, it'll be over before we know it :)
If you watch the press conference from a few days ago they say that their aim is the complete opposite.
> Does it make sense that a virus would evolve to favour these conditions?

I strongly doubt that COVID-19 has been exposed to NSAIDs long enough to result in evolution of any type. The paper suggests that NSAIDs make us more biocompatible, so it really is just a coincidence. Lots of medications have contra-indications.
So you are saying ESR has a conflict between a virtuous principle which led him to use obscene language (is that autonomy?) and the upper class virtuous principle of courtesy, and he's subordinated courtesy because he's working class?
The Soviet Union ended 30 years ago and reducing China's government to "communist regime" is at best naive and ignorant and at worst deliberately misleading.
You realize the person in charge doesn't know what the Marshall Plan is and only know "the art of the deal."
You seriously want to have a county that is touting America First for the last 4 years in control over medicine that might cure or at least protect your fellow citizens instead of your neighbor and biggest trading partner that is also part of the same governing organization?

You have to be a troll or have a very strange agenda, seriously.
I don't think they are afraid. There have been a series of protests. When he was first starting in office there was a march for science,for example, I went to that one. I (like many others, I'm not special) at the 2016 election I left my city and went out in the countryside to door bell for a us representative in a close race, turning over the seat to dems - that was a little scary.

But I'd like for there to be public demonstrations, I was hoping somebody else would organize. I should have done something of course. Now it's too late, at least a little unsafe to assemble in large crowds.
Well in the case of Italy it seems to have led to strikes by food workers who would like to go home https://www.politico.eu/article/coronavirus-sparks-nationwid...
This is my understanding, but I'd love to hear what others have to say:

My understanding is that the coronavirus is viral, not microbial, so we don't have any medicine to cure it directly (antibiotics don't work on it).

In addition, the risk is from having a respiratory problem, either from this or from something else (like pneumonia).

So if you get coronavirus then the basic treatment is to put you in a hospital to help your body live through the respiratory problem until your body can fight off the virus on it's own.

That's why there's so much emphasis on slowing the growth and flattening the curve. If (when) all the hospital beds fill up then whoever doesn't get in will have a much tougher time surviving, and there's no treatment other than having people lay in a hospital bed for a couple weeks.

tl;dr: It's not a chronic condition, but you'll need several weeks of intensive care to survive. ERs themselves just diagnose, treat what they can in the moment, and then send people home or on to the hospital.
That's not the elephant in the room. That some obvious speculation over the contents that everybody will understand but has no place in a scientific paper.

Or, in other words, the paper's title does mean "hey, we got some more evidence that poverty causes authoritarianism (or the other way around)", it's just encoded in Academish.
This is a nice reminder that some things just aren't amenable to automation. Things shift too often and/or the number and type of exceptions just aren't worth automating.
> What's more "America First" than making sure only America gets a vaccine?

America developing a vaccine first and sharing it with the world for free would be more "America First."

That such an idea sounds laughable shows the effects of 20 years of neoliberal wankery mushing the brains of Americans.
You are correct, but the government is saying "4 weeks". Terrifyingly.

UK is completely unprepared for what's about to hit.
First hit on google "coronavirus ibuprofen"

https://www.theguardian.com/world/2020/mar/14/anti-inflammat...

>French authorities have warned that widely used over-the-counter anti-inflammatory drugs may worsen the coronavirus.

>The country’s health minister, Olivier Véran, who is a qualified doctor and neurologist, tweeted on Saturday: “The taking of anti-inflammatories [ibuprofen, cortisone … ] could be a factor in aggravating the infection. In case of fever, take paracetamol. If you are already taking anti-inflammatory drugs, ask your doctor’s advice.”

This is HN right? I'm sure when you find an ImportError you know how to look things up on SO, how come people have trouble transferring this very simple knowledge-learning process to other domains?
You're right, I'll edit to to "authoritarian" regimes. What I meant was that authoritarian goverments cannot afford dissent and try everything to supress.
I come from FreeBSD where we have an amazing package manager but a “keep it lean” mentality. If a package isn’t on the package manager (the repo is great but nowhere near as expansive as Debian or Fedora) or if I want to build from source, I shouldn’t need to install such a huge system dependency.
Good point on Marshall Plan. But "Modern Europe nearly owes its existence to the herculean efforts of Americans" - really? If you're talking about ww2, Soviet union had a far more important role to play. https://www.vox.com/2014/6/16/5814270/the-successful-70-year...

Ya, labels suck. I'm "liberal" in the sense that I support whatever works and embrace change. Adam Smith, Marx, others all made some great points, many of which have been lost, but progress marches on and we must adapt.
>and the virus is more deadly.

Explain this, because this is the part I just can't wrap my head around. How is a disease that's deadly towards a much smaller percentage of the population 'more deadly'. Children aren't affected, anyone under the age of 60 is mildly affected barring pre-existing health problems. How is that more deadly than, a 30% mortality rate for young otherwise healthy individuals in the case of 2009's pandemic?
Right.

I think Worstall is correct that the story only makes sense if the pay decision can be generalised to other companies, otherwise it won't have enough effect on the market.

But there's no good reason to generalise "Ford workers should be able to afford cars" to "company X workers should be able to afford company X products".

Rather it should turn into something like "Factory workers should be able to afford cars".
I live in the UK and volunteer on the front line; current events won't stop me doing so irregardless of the risk to myself or my family. The comments here on the UK's response are disappointing to say the least and just the product of modern day hysteria. No one knows how this is going to play out, so stop pretending to have some great insight - just focus on protecting yourself, instead of spreading fear, if you are that way inclined and let the rest of us get on with handling the situation.
What's your opinion on "libman", also mentioned in the author's blog post?

https://github.com/vector-of-bool/libman

The author defines it this way:

> libman is a new level of indirection between package management and build systems. If a package manager can emit libman files, then any build system that understands them can work with that package manager. If a build system can spit out a libman-export, then a package manager that understands the format can collect the build output and distribute it.

Do you see some values in this? Would that be something helpful for your project? As far as I understand, "dds" is just one emitter and consumer of a libman manifest, but the author seems to that it could also be used in combination with other tools (such as cmake as the build tool, conan as the package manager).
I can’t scroll if any chart is under the scroll point (iPhone).

Anyway, please don’t shade countries by number of cases and use percent of population instead.
The UK is a funny combination of collectivism and individualism. The NHS, BBC, the Blitz spirit, but also small-c-conservatism, almost always slightly-right-of-centre governments, the Monarchy. It's culturally mid-Atlantic - somewhere between the European way and the way in the United States. And that's pretty much how they're responding to this crisis, isn't it?
Congress has the authority to regulate interstate commerce.
I don't think downvotes are happening because "trolls". They're happening because you're engaging in attacks against people instead of ideas.

There are people here having meaningful conversation on both sides, then there are people such as you who are simply spitting venom.

You may be worried by the current events going on, but please remember that everybody here - even those you disagree with - are human beings.
A few ways viruses can cause long term issues:

- You don't get immune due to strains and changes (flu)

- You get it forever latently and it comes back from time to time (HSV)

- malignant tissue abnormalities, Cancer, organ failure over time (some HSV strains, HEP)

- You get immunity but if another strain hits you you bleed from all orifices and may die (dengue)

- It stays with you forever and makes you more vulnerable to tons of other virii (Eppstein-Barr - I know, killer combo, HSV, HEP)

- Chronic fatigue syndrome (Epstein-Barr)

- It depletes your immune system leaving you vulnerable for life (HIV)

- Permanent lung, liver, kidney or heart damage (SARS)

- chronic joint and muscle pain, vision and hearing loss, abdominal pain, bleeding, malaise, and psychological problems (Ebola)

- birth defects, chronic joint pain and inflammation (Zika)

We have NO IDEA right now if this one has such effects or interactions ... it's too early. But we have indication for several side effects from Wuhan that are being studied like permanent lung scarring and T-cell exhaustion.

So this "strategy" (They would all speak German if they used this to save the economy in 1940) is beyond madness.

Please please please do not take this lightly with a I'll get it anyway attitude. More time buys understanding, treatment, lower severity and better survival chances.

(Same reason to be cautious with rushed vaccines (well tested ones are just fine) - especially if they show up unseasonably early for election time. Read up on the Philippines dengue vaccine for the gory details)
This was my interpretation, too. If you watched the presser, it was clearly about a website into which you could enter your symptoms and then be directed to a testing site if needed. Nationwide. Verily’s first set of subsequent statements refuted this.
I wish more ppl would have experienced include files, so that they would see the advantage of lexical scoped namespace module imports. With no shared global scope. So that you can see where all variables come from at a glance. With the ability to import any library anywhere in your code with just "var foo = import lib" and it will just work. (See Dlang and nodejs commonjs modules)
