As far as I can tell, the only way to contain this would've been if every county on the planet had cut off travellers from China in January and tracked down and quarantined those already in the country - something China actively campaigned against with the support of the WHO. All of the countries that have contained this relied on that combined with contact tracing and testing once one became available, even China itself. Just testing and tracing alone hasn't worked anywhere. So it's less "wasted all the time China gave us" and more "trusted what China was saying, not what they were doing".
Am Dutch, can confirm the article is reasonably summed up with the title. From the article:

4x resources delay a crisis by 2 doublings.

If a doubling takes 7 days, that’s just 2 weeks.

R0 (reproduction rate) overwhelms everything. The only way out safely is to greatly reduce R0:

- social distancing: 6-9 feet away from everyone

- avoiding crowds

- Never share utensils; no buffets

- hygienic routines: wash hands, use wipes, close toilet lid before flushing (see Amoy Gardens), etc.

And convince others to do the same.

Italy closed schools when they had just 150 confirmed cases but still in a tragic crisis because people kept socializing.

Just as with crypto mining, I'd recommend to set up a new Folding profile on your GPU settings. You want to be controlling GPU power limits eg reduce it by a bit and adding a more aggressive fan setting.

I applied this strategy when bitcoin mining on my 1080ti which I got shortly after release. I was aiming for sub 60c temps. The results paid for the GPU, and I didn't fry it either - still my daily driver today.

(The 1080TI is / was such a beast, with exceptional value for money.)

It's not just live or die you know. Reduced quality of life is a possible out come too:

>Similar to patients with SARS-CoV and MERS-CoV, some patients with 2019-nCoV develop acute respiratory distress syndrome (ARDS) with characteristic pulmonary ground glass changes on imaging. In most moribund patients, 2019-nCoV infection is also associated with a cytokine storm, ... in those who survive intensive care, these aberrant and excessive immune responses lead to long-term lung damage and fibrosis, causing functional disability and reduced quality of life.

Instead of banning them, how about Amazon work with these guys to find an agreeable price to sell these at? They have what we need. They've incurred costs. Maybe there's a win-win.

This guy's a moron, but here's a cautionary tale:

A relative in Florida was complaining after a hurricane that he was being gouged. Building materials were a lot more expensive as was labor. However, he was able to get his house repaired pretty quickly given the scale of damage in the area. The higher prices incentivized the movement of goods to the area, and also caused a lot of tradesmen to travel hundreds of miles to the area for the work.

Florida passed an anti-gouging law.

The next hurricane came through, and my relative could not get his house repaired for almost a year. There was no incentive for tradesmen to relocate to the area, so there was a huge shortage. The cost of moving material to the area could not be covered because you couldn't charge more. He finally resorted to driving around and talking to crews doing work. He eventually found a crew that would work for him on their off time "off the books" - for a high price.

Absolutely. From the WHO page [0]

> Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

The problem is that some people forget that between "common signs" and "severe cases" there's a vast area of very uncomfortable symptoms until you get to the severe cases, and we're currently still learning about this very gray area.

What kind of wicked education you had for this to be the case?

My dad taught me about bits and bytes and words when I was a kid, and by 16 I had a quite solid grasp of it (without any textbook). Then I studied several years and got a phd in applied math (mostly numerical pde, and that involved a lot of programming). Then I have spent 15 more years doing math and programming in several languages (mostly C and Python) and getting paid for teaching data science and signal processing to people who got on to have fruitful jobs in industry. Today, I read the wikipedia page about "option type" [1] and the one about about type theory [2], which seems a prerequisite, and couldn't understand a word.

No, this is worse than a cold. Worse than the flu as well.
For 18 to 49, the death rate for flu last year was 1.8 per 100,000 people. Corona virus's death rate is unknown but even among 20 somethings they are talking about an estimated .2% death rate. That's 200 per 100,000 https://www.cdc.gov/flu/about/burden/2018-2019.html

In numbers, yes, but, quoting from reddit:

```
I agree AOM is the best quality now. But between Rav1e and SVT-AV1 it's not so clear for me. When you look metrics, SVT-AV1 is clearly the winner. But when I do side to side comparison ( e.g with online comparison tool like https://svt.github.io/vivict/ ) for me SVT-AV1 blur too much and don't have the same details retention than rav1e and I found rav1e much more pleasant ( my opinion) . I hope at some point there will be some real human a/b testing study.
```
To be fair YouTube isn't (or wasn't a few months ago) at the stage where AV1 was earning it's place. They project that it will save them money in the future (widespread hardware decoder will let them send bigger encodes to more people) but at their video symposium they said that they were doing this at the moment as in investment for the future.

Which is cool, but means other orgs that are only interested in cost savings may not want to jump in quite yet (though they should probably be preparing so they can switch it in when that point arrives).

For middle age people, if you are unlucky and get other virus at the same time(because you met with lots of people in a place), like the flu, it can be extremely dangerous.

Last year I catched two virus at the same time and it was so painful. My body reacted too strong with an autoimmune reaction, attacking my own body, my joints, my muscles.

It took me two months to properly recover, and I live a very healthy lifestyle. I sleep and eat well and exercise. The doctor told me that someone in the same situation that smokes for example could develop lots of complications.

Do as I say, not as I do. Hear hear.
What always annoyed me about C is that it has all the tools to simulate something approaching this, save for some purely syntactical last-mile shortcomings. We can already return structs; if only there were a way to neatly define a function returning an anonymous struct, and immediately destructure on the receiving end. Something like:

#include <stdio.h>

struct { int err; char c; } myfunc() {
return { 0, 'a' };
}

int main(int argc, const char *argv[]) {
{ int err; char c; } = myfunc();
if (err) {
// handle
return err;
}
printf("Hello %c\n", c);

return 0;
}

This is (semantically) perfectly possible today, you just have to jump through some syntactic hoops explicitly naming that return struct type (because among others anonymous structs, even when structurally equivalent, aren't equivalent types unless they're named...). Compilers could easily do that for us! It would be such a simple extension to the standard with, imo, huge benefits.

Every time I have to check for in-band errors in C, or pass a pointer to a function as a "return value", I think of this and cringe.
We don't have to focus on every crisis. The context here is zoonotic spillover, which has killed millions of people historically, and it keeps happening again and again.

It's still okay that we didn't listen to experts like this last time. But this serves as a good wake up call. Avian flu didn't wake us. Swine flu didn't wake us. We were distracted when Spanish Flu came around. But let's not have this repeat too many times.

Further, that assumes that the healthcare system can perform heroic efforts. In cases where the system is overloaded, such as seen in Italy, mortality numbers can get much worse. Now add that some/many patients have lung scarring that can hold with them for life.

With all of the information available demonstrating that it clearly is pretty serious, I've come to identify people downplaying it as essentially the exercising of wishful thinking: If I tell everyone it's nothing, maybe it will be.

I hope it's nothing. At the same time I understand the responses that have occurred.

“Do not log specific things, just pay for a service that logs everything”

The false dichotomy between monitoring and logging here is so bizarre, they’re not mutually exclusive. When an alert wakes you up on a weekend, having a log statement with useful context is not going to kill you...

Also:

> Isn’t it a bit too hard?! Look, I just want to write strings into stdout. And then store it somewhere.

So do that? Why is the author pretending you need to use ELK stack?

And what about their example is “too hard”, if you’re deploying your own application that’s the least of your complications, and if you aren’t and already paying a premium for it, there’s plenty of managed ELK and ELK-like products (and I’d also be surprised if your managed deploy platform doesn’t already support you just logging to STDOUT)

A vaccine dose proactively creates memory cells (memory B cells) in the body, which allow the body to IMMEDIATELY create fighter cells (plasma cells) when the body is infected with the actual virus, thus stopping it in its tracks. Without vaccine, when virus infects, the body takes times to learn the virus and create the memory cells and fighter cells, and hence the infection gets worse.

The weapons the fighter cells use are antibodies. In this case, the discovery has directly produced antibodies, which are helpful in fighting the virus (but cannot be used to proactively create memory cells). Antibodies have the advantage that they don't trigger the body's immune system, which means less issues to deal with.

Hope this (and other efforts being done) pass testing and get in the field as soon as possible.
For any sufficiently large organisation, they will have parts of the business that are in "wartime" and parts that are in "peacetime".

The great CEO is able to manage their organisation to handle both. But odd are, you won't see this. Because they know to do that effectively, their "all hands" messaging has to be bland, tending towards peacetime messaging - or risk spooking the peacetime parts of the business. But then when talking to the wartime parts of the business, typically much smaller audiences, they are aggressive, and encourage the single minded focus of the leader of that part of the business.

Simon Wardley has many many good articles on this topic, often with the military angle - because war is the ultimate expression of conflict, and business are always in conflict with something.
A couple things being done to help reduce pressure on medical personel here in Czech Republic:

This article doesn't look at the usecases for logging.

In my mind, there are audit logs, to know what happened during an incident. You don't know what the incident will be, so you should log as much maybe-useful stuff as possible, and you only look at the logs if some incident requires attention.

There also logs to debug an issue that occurs in production but can't be diagnosed any other way. When a customer says "I clicked the log in button, but just saw a blank screen", and you have no other records, the logs will be handy.

> I think the most important part in the article is that with the wave of populism and nationalism sweeping the world it's evident that this mindset is incapable of solving any real problem on any scale.

Less globalism, less ability to freely travel == less risk to spread the virus from country to country. If anything, nationalism does the contrary of what you claim it does. In fact, by closing their border right now, countries are insuring that no foreign traveler is going to bring now CORONA cases to their country.

If nobody could travel to and from China, the global pandemic would not have happened.

What’s Holding Women Back? - Harvard Business Review
The leveldb solution is quite straightforward (running in ipython3 for easy benchmarking with timeit):

import leveldb,hashlib
db = leveldb.LevelDB('db')
def lookup(pw):
m = hashlib.sha1()
m.update(pw)
try: # the leveldb api is a bit minimalist..
db.Get(m.digest())
return True
except:
return False
%timeit lookup(b'password')

Creating the database was just calling db.Put(x) for every entry.

The numpy solution is also quite easy (db3 is essentially your ..|cut|xxd .. file I think:

import numpy as np
db = np.memmap('db3', dtype=np.dtype('S20'), mode='r')
def lookup(pw):
m = hashlib.sha1()
m.update(pw)
idx = np.searchsorted(db, m.digest())
return db[idx] == m.digest()
%timeit lookup(b'password')

And I was running this on a system where not even db3 (which is just the binary hashes concatenated) would fit into my RAM, so for "real world" applications the results would be much worse since it's more limited by the disk IO than what's running on top. I just reran both and got 3us for the leveldb solution and 13us for the binary search/numpy solution.

I think they have handled it pretty well. I'm pretty sure they spent some time talking to experts. I've worked in a research project on crisis management before and have a very high opinion of the Robert Koch Institute which was one of the partners (and am generally quite critical of government organizations).
Given the political infrastructure (states can make the decisions in many areas), I think the reaction was pretty good so far. One of the major concerns is always avoiding panics. I'm pretty sure they are balancing all official statements against that.

Tbh. the most important thing for me is that you listen to experts and don't overreact.
> There's no way to instantly convert the stablecoin back into the collateral asset, you have to find someone with a CDP who is willing to buy the stablecoin from you.

This is incorrect and actually doesn't make sense. An important part of DeFi are DEXes (decentralised exchanges) such as Uniswap and Kyber. There is a liquidity pool where you can instantly buy/sell assets. There is no 'waiting' to find someone (i.e. no problems with coincidence of wants). You definitely do not need to find someone with a CDP. You can hold DAI without opening a CDP. Contracts can hold DAI (as DEXes do).

> Similarly, there's no way to unlock your collateralized asset, you have to find someone who is willing to sell you the stablecoin in order to open up your vault and get your eth out.

Also incorrect. You need to pay back the debt of your CDP with DAI. You can do this easily by buying DAI on a DEX, paying back the debt, then releasing your collateral. Some services exist to do this in 1 transaction, so you don't need to actually 'buy' any other asset. You just send the transaction to a contract and they take care of the details.

The DeFi, specifically the Ethereum space, has moved very quickly in a short amount of time, so there are a lot of new concepts and instruments out there. I think a more traditional finance person will have trouble understanding it all as in some cases, there are no analogies to the traditional finance system (e.g. flashloans).
