Exponential growth for a short period is seen in every epidemic, even small ones, because they all follow the same bell-curveish sort of shapes. Having observed that by itself doesn't mean anything - all epidemics grow slowly, then quickly, then slowly again as they approach their natural saturation point, then go into decline.

The idea that COVID-19 would grow exponentially starting from zero until a saturation of 100% was reached was only ever the outcome assumed by simulations, which have - as far as I can tell - a perfect track record of total failure. At least the sort of models created by universities in the modern era do.

To make this clear, the UW model driving much US policy response was updated several times in real time yet despite that managed to make wrong predictions for the exact same day it was updated.

And not just wrong, but reality fell far outside this models own uncertainty bounds too, so according to the modellers observed reality was not just unlikely but almost completely impossible.

(note how wide the uncertainty bounds are, yet that it's still wrong)

The Imperial model that drove the UK ignored the possibility of hospital capacity increases entirely, and comes from a team that has (as far as I could find out) never successfully predicted an epidemic.

Real diseases don't play out like unending exponential growth until the whole world is infected - they go into decline far before that.

Quite why this is so is unknown. The dark secret of epidemiology is nobody really understands viral spread. Every model is wrong and nobody can explain why. Germ theory must have a major gap, so what is it? My guess is a combination of much higher asymptomatic spread than currently understood (asymptomatic infection not being a phenomenon that's really been investigated much as only academic modellers care about it), and perhaps some forms of natural immunity to viruses that aren't based on antibodies.

Whatever the cause, it'd be wrong to compare the observed outcomes vs the predictions from models that are known to be completely useless and say, there's been a decrease.

US Covid-19 Test Results: Making Progress
Good time to buy some Facebook stock then.
How many flights does NYC receive per day?

How many does Seattle receive?

The current state of both cities has nothing to do with what they did or didn't.

Same thing with Europe. The most affected countries are the most visited ones. Which also makes me question about the effectiveness of lockdowns.
Okay, then, argue it.
Hustling and the art of not scaling in order to scale
Lots of amazing SDF examples run at 60Hz, are you thinking of some specific examples that run at 3fps and below?

It’s not really fair to compare SDF with rasterizing using a game engine that has bounding volumes. They are different things.

Some of the terrain & grass SDF examples run faster than any raster engine can ever do it.

> you’d still arguably be better running it on 4 quads

Nothing about the article precludes doing that, right? The technique would work without modification if you attach it to some quads and leave out the middle. Probably even better yet, just exclude the middle from any calculations in the shader and use 1 quad...
Absolutely disagree. This was the case for me at average high school and college in the midwest. I'd say ~50% of the populations had those pressures.

Going to a upper tier college for grad school showed me that only the percentage changes, going from maybe ~50% to ~75%
“The government” should use their surveillance facilities to penetrate companies like that and destroy them before they start hemorraging taxpayer money.

I am surprised they still haven’t used that as a way to justify surveillance policies.
I don't see it as ambiguous but I see what you are referring to.
San Francisco is around 60% of the density of NYC. Outside of the US, cities like Taipei, Hong Kong, and Seoul are all similarly densely populated and have largely avoided the problems that have befallen New York due to quick responses and smart planning.
Virginia isn't doing it either. Northam (a doctor) doesn't have a clue as to what he is doing.
We're not stopping the spread of covid, with or without "hoaxers", this is going to run its course.

We're just slowing it to a manageable rate with fairly extreme measures like lock-downs (which will likely be loosening soon anyways), and I don't see small pockets of uncooperative people making a sizable difference in the general outcome, not at this stage.
> That and the ability to install a package in a shell, use it, then exit the shell and not have it installed globally is amazing.

I can't even count the number of packages I have installed because I needed them once. I have an entire Node.js ecosystem installed because I needed to run a frontend from another team for 20 minutes. Could I have done all that in a single shell, then had it automatically cleaned up when I was done? My current solution is to spin up a container, but that becomes a pain and I end up getting lazy and just globally installing everything again.
Asking as a non-native speaker, how would you write this sentence instead? I tried but cannot produce any syntactically correct alternative better than this.

In the german wikipedia edition 814 mSv/a is mentioned (based on the linked study) for Ramsar, Iran. To be fair, a comment has been added stating:

"Allerdings dürfte bei etwa 33.000 Einwohnern Ramsars die Kohortengröße von weit unter 5 % für die über 100 mSv/a Exponierten wahrscheinlich zu gering sein, um statistisch signifikante Gesundheitsfolgen festzustellen."

Translated:
The size of the measured cohort of 33.000 inhabitants of Ramsar of less than 5% for >100 mSv/a exposed participants is probably too small to allow to derive statistically significant health-related conclusions.
Yes, NYC had factors that made it particularly susceptible in a global pandemic of Covid-19: (1) high density (as you say), (2) lots of international travel to and from NYC, (3) heavily used public transit (covid virus lifespan on metal surfaces -- like poles people hang on to in subway trains -- is long).
That goes back to the 1980s, with UCLA Locus. This was a distributed UNIX-like system. You could launch a process on another machine and keep I/O and pipes connected. Even on a machine with a different CPU architecture. They even shared file position between tasks across the network. Locus was eventually part of an IBM product.

A big part of the problem is "fork", which is a primitive designed to work on a PDP-11 with very limited memory. The way "fork" originally worked was to swap out the process, and instead of discarding the in-memory copy, duplicate the process table entry for it, making the swapped-out version and the in-memory version separate processes. This copied code, data, and the process header with the file info.
This is a strange way to launch a new process, but it was really easy to implement in early Unix.

Most other systems had some variant on "run" - launch and run the indicated image. That distributes much better.
That's not how amplitude and phase work, you don't "set them" on a microphone.

Filtering sources isn't new, of course, and doing it manually fiddling around with a recording you already made is one thing.

But doing it in automatically in real-time on equipment with unknown characteristics that leaves zero ghost signal behind... is, yes, insanely hard.
I read this article long back and it really resonated with me https://threader.app/thread/1218724150312751104 . It explains why people solving problems proactively before they become huge issues get much less credit than people doing it reactively when the problem has become much worse and putting heroic efforts.
Why do you find it interesting that they didn't switch? What is the compelling reason to switch if you don't care about Oracle owning MySQL?

The only difference I remember from having been forced to use MariaDB in the past was that one of the 5.x releases didn't support NOT NULL virtual columns when the equivalent 5.x MySQL release did support them... to me, MariaDB is just a strange, slightly incompatible fork, but maybe someone else here has more experience with both. (I prefer postgres)
> The hoaxers

A minor but salient point: in common usage, a hoaxer would be a person perpetrating a hoax, not a person who believes (incorrectly) that someone else is perpetrating a hoax. The people who you are referring to hear are better labelled "denialists" than "hoaxers".
It's nice to see people re-discover old school tech. In cluster computing this was generally called "application checkpointing"[1] and it's still in use in many different systems today. If you want to build this into your app for parallel computing you'd typically use PVM[2]/MPI[3]. SSI[4] clusters tried to simplify all this by making any process "telefork" and run on any node (based on a load balancing algorithm), but the most persistent and difficult challenge was getting shared memory and threading to work reliably.

It looks like CRIU support is bundled in kernels since 3.11[5], and works for me in Ubuntu 18.04, so you can basically do this now without custom apps.

I am just amused at all the gravity assist loop de loops portrayed in The Expanse. That seems to take just 10 minutes at a time...

At any rate I suppose computers in the future can calculate these multiples of assist trajectories on the fly...
Vast simplification that undermines working-class people. Tens of millions of people have lost their job and income, while bills continue to accumulate. It's fair to acknowledge the potential risks of contracting COVID-19, and still decide, I'd prefer to work, observing sanitization & social distancing measures, than to have my entire financial life ruined.

We just had the NFL draft this week. Plenty of these players will have their bodies seriously harmed in the next few years, while others will get multiple concussions and potentially set themselves up for CTE or other brain damage. Not once did anyone raise any alarms about, maybe these young people shouldn't go into this line of work...
We had Pink Floyd and lawn darts. Damn I'm old.
The world isn't software engineering; if anything, it's philosophy.

I look at it this way, and it sounds harsh but it's big-time decision-making life:

1. You could compel people to listen to something to ensure their safety by force, and then have a riot.

OR

2. You could urge sensible people do something for their own safety while letting the idiots commit suicide and clean-up the gene pool in the process.

I say take option #2 all-day, everyday because it's easier, cheaper, and better for others who do listen to have one less fewer, stupid liability in the world who would otherwise put others in danger.
To be a truly scientific study, we need to look at more than two instances of scientists leading and not leading.

What we should do instead is try to make sure other people can understand what we are trying to say.
I think it's worth noting that the UNSCEAR report also said 5000 more deaths among less exposed people (so 9000 in total), it's all rather arbitrary.

New York already has an underground steam system. They're constantly digging that up for maintenance. While they're in there maybe this could be installed.
I think this kind of retrospective look at these two datapoints is probably not focused on the right thing at this point.

This article picks on DeBlasio / Cuomo and indirectly DeBlasio’s health commissioner heavily for encouraging continued going out to restaurants and events and riding the subway in late Feb and into mid-March. But remember in late Feb the President was still saying it was going to just magically go away. Bay Area politicians including the speaker of the house Pelosi were encouraging lots of people to come to Chinatown parades. Florida even left their beaches open all the way through mid March for spring breakers to come. While those events have almost certainly led to additional cases and deaths, other areas of the country seem to have largely gotten away with a less proactive and later response than Seattle.

I think we are probably going to see that the real challenge on NY is that we just don’t have another city in the US with New York’s density, air travel volume, and high utilization of public transit. Comparing NY to Seattle just because they are both in the US is probably not as relevant. Given what we know now about the propensity of high volume super spreader events to drive the bulk of the R0, NY can probably only really fairly be compared to London and Paris in the Western world, at least.
Has Labour ever been in coalition with anyone for an extended period?

Reality is Labour lost the election despite going up against an incredibly weak opposition and basically refusing to discuss or take a position on Brexit, which was an irresponsible form of electioneering. When faced with a competent opposition they took the same approach and were wiped out. That's on Corbyn.
No but the Feds have already shipped supplies, built hospitals and closed travel to China & Europe.

NYC has the economy of some small countries and they do have the backing of the Fed, no matter what excuses Cuomo gives.
They could have started pushing social distancing measures earlier. Also, they might not be able to close airports on their own but if I am not mistaken screening and quarantining is something they could have started enforcing(or more strictly if they were already doing it).
I would rather take 100 "idiots" in the gene pool for genetic diversity

Of course, "idiot" is pretty relative, and not everyone going out is an idiot, but that would undermine your eugenics argument
> basically three groups of people now

I can imagine more groups. For example people might need to get out of the city/house for psychological reasons. Taking a small chance to get/spread the virus might be better than hurting oneself/others.

> OK, correcting you since you're wrong: It's not just New York City that's done badly, but smaller cities and areas of upstate New York that are quite similar to large parts of the rest of the country (that have done comparatively better).

If by upstate NYC you mean Westchester County, that's still largely affected by the spread of the virus in NYC given how interlinked the two communities are.

Going by https://www.nytimes.com/interactive/2020/us/new-york-coronav..., NYC is the most affected per capita, with Westchester placing #3
> other areas of the country seem to have largely gotten away with a less proactive and later response Seattle.

This assessment is really premature.
No, I'm sorry, you're missing the point of the article. One of those places had politicians using more economic and political considerations leading to their choices. Seattle has those forces but generally acceded to the guidance of scientists.
Option 2 doesn't really work with an exponential process. There are people who have to work for society to continue functioning who have no choice but to be exposed to the "idiots", and even people able to self-isolated generally cannot completely remove encounters that could cause infection, but instead just greatly reduce them.
More specifically, NYC/NJ had lots of flights from the European epicenter. The west coast has more flights from Asia, which had a comparatively small number of cases.

I think for various reasons that population density metric does a bad job of capturing density as a metric relevant to infectious diseases. The percent of the population that uses public transportation is a probably a more relevant metric, and in NYC that might be over 100%, since so many non-residents use it.

I didn't mean to imply that DeBlasio might have locked down NY City 10 days earlier; just that he probably would have done so a couple days earlier. And even a couple of days might have helped.

I think he would have because DeBlasio implemented quite a few restrictions earlier. On the 13th, he cancelled large gatherings and limited smaller venues to 50% capacity.

https://www1.nyc.gov/office-of-the-mayor/news/138-20/mayor-d...

On the 15th, he issued an order closing bars and restaurants,

https://www1.nyc.gov/office-of-the-mayor/news/152-20/stateme...

and closed schools.

https://www1.nyc.gov/office-of-the-mayor/news/151-20/new-yor...

Even San Francisco didn't issue a lockdown order until the 16th, and Washington state was even later than NY. I don't remember anyone considering a lockdown on the 10th.
Yet there has never been a global bank that supports verifying identities in almost every country.
I went to a school with similar dynamics, and if it's any comfort, I can assure you that the bullshit doesn't pay off. Those of us that pursued our interests deeply had our pick of college, those obsessed with simple metrics like AP count and SAT score got to what you call second-tiers if they were lucky, and those chasing leadership positions in do-nothing clubs got sweeping rejections. The system is not fair by any means, but it's not stupid, it can recognize people trying to game it.

Not really, not in a prison: Droplets exist in a continuum, and while most are large enough to drop out of the air, as they get smaller they stay in the air longer, and require less air current to stay aloft. [0]

As such, while the small particles may not exists in sufficient quantities when it is just one infected, or a few infected inmates, but with each infected inmate the concentrations of those small particles will increase. Let's say they're normally 0.5% of the total particle exhalations: 10 inmates get sick through direct contact, and their combined exhalations bring the quantity of smaller, longer lived particles up to an equivalent of 5%. More get sick through contact, bringing it to 20%. At some point, you hit a critical mass where there is a sufficient concentration to infect people, and creates a downward spiral from there.

There is an app on the google play store that claims to be an “antivirus/cleaner” app that abused Androids accessibility API’s to access WhatsApps media files. The developer called it a “WhatsApp cleaner”. The app was removed from the Play store for several weeks but was allowed to return. The developers now claim to PROTECT unauthorized access to WhatsApp’s media files. App is affiliated with China’s Qihoo that was booted long ago from the Play store for hijacking users WebView with fake virus warnings to boost installs. As this app has been doing every day since 2013.
