Second hand (I wasn't there at the time), but Apple had more than anything a management problem. Managers making a land-grab put everything+kitchen sink into Copland. It was an incoherent mess. Then the VM folks would decide to rewrite the VM subsystem and Copeland would go a month without a single usable build.

Steve and the management team he brought in essentially fired all the MBAs and non-engineering managers. Copeland was doomed by bad management.

No one said anything about only "rich people" "deserving" anything. If you draw the conclusion that only "rich people" will have access to something if the price is higher (notice they didn't specify how much) that's fine, but don't go putting words in other people's mouths.
You need the tools, but you don't have them. So you need the tools that make the tools. But you don't have those either. So you have two layers of tools you need to make from basic tools. Then you need supply chains for all the inputs. It's not as easy as waving a magic wand. But I do suspect that if we had started in January something could have been done.
Easiest way to get this number: estimate actual/confirmed case ratio is 10x, and estimate a 5-day infection doubling time. That hits the projection almost exactly.
I wonder what if there's a straightforward way to make facemasks by hand, or with tools that are generally available?

I'm imagining cutting apart a furnace filter and wrapping the fabric around a wire frame, or something like that. If someone were to develop a process that was simple and reliably repeatable and produced good quality effective masks, that could be a way for otherwise un-busy people to keep hospital staff supplied.

One issue I suppose is whether there are upstream bottlenecks, like not being able to get a reliable supply of the right kinds of filter material.

> ...disliked ZFS because they feel it was designed to be incompatible with Linux...

Ya... That may have just a bit to do with the fact that ZFS is released under a licence that was explicitly designed to be incompatible with Linux.

"Mozilla was selected partially because it is GPL incompatible. That was part of the design when they released OpenSolaris. ... the engineers who wrote Solaris ... had some biases about how it should be released, and you have to respect that."

I can see how that might suggest to Linux maintainers that they are not welcome to use this code. Maybe sorta.
I'm not saying the courts and police will be evicting people if ordered not to, I'm saying I doubt the landlords will be happy about their income suddenly getting slashed. And furthermore, believe that they will still threaten evictions with their trademark red, bolded nastygrams and loanshark-level harassment, even if it doesn't have any legal teeth.

Or are you earnestly suggesting that slashing someone's income will not result in them vocally trying to recover that income? We're under pandemic, not in a bizzaro universe. Landlords are gunna landlord.
You will care if you need treatment but the hospitals are understaffed because all the healthcare workers are sick.

Again severe failure on the govt’s part. Their inaction in when it was needed the most led to all these circumstances that makes it ripe for situations like these. As the number of infections spread and economic situation get worse these kind of things will get really really bad. Once the second and third order effects kick in it’s going to be a catastrophe. And our leaders answer to all of this is to give $1200 checks to people. All they care is about the economy as it gives them higher odds for their reelection. I don’t understand how such incompetence can be tolerated and why they are not fired and instead have to wait till next election.

The Imperial paper said that 2 months doesn't really flatten the curve enough to kill it off, given where we already are. You're just moving that peak to a later date, but it will still vastly exceed the healthcare capacity (we can't upscale it 8x in that amount of time).

Hence their conclusion is that we'll have to basically do this on and off, flattening the curve just enough that we can let it rebound for a while without overwhelming the system, until vaccine is available. Which they estimate as 18 months, out of which 12 will be on lockdown - however you space it out.

So yeah, the economic impact will be massive. But it doesn't have to translate to people dying, if we focus on preventing that. One person could feed themselves and others with the fruits of their labor since the agricultural revolution. It's a question of distribution, not of availability.

nrp can i reach out to you via email? what is your email?
Yes. It would also encourage exactly the kind of resiliency that many commenters here think the government should mandate by law.

If you can legally sell your masks in time of crisis for a hundred dollar a piece, that's a great incentive to keep some spare capacity around that doesn't rely on global supply chains. Price controls dull the edge of that incentive.

(If more people were allowed to raise prices and thus kept spare capacity around, prices wouldn't rise so much in the first place.)
Are you sure you can afford to? A lot of the online services charge per user.

For example we reduced the number of users in our Salesforce instance to 1 user per department and this is saving us approx 30000EUR per year which for our small cash strapped startup is significant.
This. There are barely any covid 19 patients yet hospitals are low on masks due to panic. Beds are still open and ventilators contrary to media claims are not currently on a shortage.

There are a lot of hospitals directing employees to sew them by hand.

There is a simple and reliably repeatable method: having a factory. Not sure what is needed but there are lots of suppliers on Alibaba for this type of item. There are lots of rumors about export controls in China, denials of the same from Chinese officials, and rumors of seizure by US customs.

Never imported medical stuff but anecdotally many US sellers are being solicited by Chinese factories looking to sell masks and other PPE into the US.
Indeed. BeOS would have made Macintosh as successful as the Amiga.
It's not that easy to make N95 masks. Other kinds of masks are better than nothing but if you're in close proximity for hours a day, probably not good enough.
No soup for them!
To be clear, I'm not affiliated in any way with them. I just like to keep track of asset disposition auctions to pick up equipment.

A virus isn't a Bernoulli trial that either kills you or entirely leaves you alone.

You could get sick and require hospitalization.

You could get sick and have permanent lung damage.

You could get sick from something else, or even break your collarbone in a car accident, and be unable to get adequate medical attention because of an outbreak in your region that you helped spread because you had "little reason to fear an infection."

You could infect and kill your mother.

A virus doesn't care how confident you are. It is just a little autonomous machine that uses your body to replicate itself. Don't behave in a way that helps it do that.

Firstly, thanks for your work, and good luck :|

Perhaps theft can explain the reduction, but isn't that equivalent to (for example) a leaky toilet destroying the room that the masks are in? In other words, perhaps it is still indicative a weakness in the hospital's supply chain that they can't make up for a sudden shortage of masks due to rare circumstances.
> native desktop app exposes a much larger attack surface

If we're talking about code executed as a result of, say, buffer overflow attacks, then the impact is the same both for the native app and for the browser. The latter, however, has way much more places where that overflow could happen! And they still happen, security updates for the browsers get pushed all the time.

(And we're not even talking about the world of XSS/CSRF attacks here! Those are pretty much exclusive to the browsers, and widen the attack surface tremendously.)
> First, OpenConnect is just a CDN run by Netflix, they could call it bunny protocol it’s just a name. But, they don’t have unlimited boxes at every ISP, in almost every case you can get P2P connections between specific users with lower network overhead than those users connecting to one of the ISP’s data centers.

They have boxes in a lot of ISPs.

If “P2P” requires you to transit your last mile to your ISPs POP and then back down to another user, and Netflix requires you to transit to the ISP POP and back out again... has P2P gained you much? In most cases downstream throughput is much higher as well, making the in-ISP cache box far better for most.

P2P has its place but it’s hard to argue its better for video distribution.
I had never heard of this framework until this happened, but now I am going to check it out. Probably a very good bit of accidental publicity
This is really neat. It seems a lot of the risk is how specific lung capacities and conditions interact with the ventilator and how much oxygen someone needs. My question to any MDs reading this: how often do you have to tweak ventilator volume for patients using one? What is the feedback loop? Blood oxygen levels?
Cases in Hubei is likely under reported, but this is probably more attributed to early test kit shortages and the fact to ramp up test requires time, etc. We have see the same thing in Italy and other European countries as well, the capacity is limited and testing itself is biased not aiming for coverage.

But what China's data can tell, is that there is a strategy out there to contain the virus, if implemented. And it takes about 2 months of total lockdown. It is probably the most effective containment in human history, but with a cost.

So the exact number of China's data isn't going to be meaningful to others, but the actions taken have implications and we should follow.
The greatest advantage of torrents is also its greatest disadvantage.

It’s distributed by nature but it relies on a network of computers (peers) to always be available. And given the asymmetric speed of most consumer grade internet connections, most peers tend to be greedy and disconnect from the mesh after the download finishes.

This is where private torrent sites stepped in and encouraged sharing ratios. Of course, most of the “peers” ended up being dedicated servers with symmetric gigabit lines rented from some host in a foreign country.

So in the end it, the patterns shifted back to data centers and “dumb terminals”

viruses “die” when they can no longer hold their infectious structure, presumably due to battling the elements (literally elements and molecules, heat, radiation, etc.), not to mention the active defenses of organisms.

it seems this virus dies in a few hours/days outside of a cozy host environment. so yes, get the transmission rate down far enough and it can die out.
The virus doubles in less than a week, so this hack (which is being used extensively in Italy from my understanding) can only by you so much time to stop its spread with mitigation measures.
Facemasks and other PPE are perishable. Also, many were used in 2009, and the stocks have not substantially replenished in more than a decade.
If you are thinking of something like this, I highly recommend switching to a more feature-full programming language -- my favorite is Jupyter notebook with Python.

Sure, the total amount of characters typed will be higher -- but you might end up doing the whole thing faster overall, as it will need less fiddling.

The notebook approach will also ensure you can inspect all the intermediate data, to make sure you parse things correctly.

And finally, if you ever need more functionality, there is always "pip3 install".
I was going to say that. Google voice or project fi is pretty good.
I predict India will be hit very very hard.

Do you think their poor can eat if they self-isolate? If you are hungry then you keep working, you have few choices to avoid social contact, and you have few resources to help you if you are sick.

Do you think India has the capacity to test enough people to effect efficient blocks against transmission? Do you trust their bureaucracy to mostly act decisively and effectively for the majority?

Do they have the social mores to cooperate with rules to prevent transmission? (I’m not judging, I have some very conscientious Indian acquaintances, I’m just unsure about the population on average).

At least they will have some medicine - they produce a lot and they stopped exporting many drugs on the 4th March.

I have also been to the wet markets in two Chinese provinces (Yunnan & Shanghai [not a province, I guess]).

At least in the most dense regions of China that I observed, the state definitely at least seemed to have the ability to enforce some form of effective mandatory social isolation. Even in rural areas, the government seemed to be able to project authority using tech.

Sure, their squat toilets are a mess but I don’t think that really reflects the technological capabilities of the state.
I thought I remembered reading somewhere recently that 2:1 is already in use in some cases (maybe in Italy?), but I can't find a source.

Is there increased risk of ventilator failure with this approach? That seems like it could be an additional terrible factor to weigh, because parts have become so scarce.

IANAL, but it seems like a grey area. He's not passing his test off as a "real" test, dispensing any medication, or otherwise acting as a doctor.

I did edit the post, but my goal was clarity not really a neutral tone. From a public heath perspective it’s important for heathy young people to avoid spreading the disease. But, that’s pushing people to be somewhat deceptive with statistics. So, while I am minimizing contact with others for my personal heath and the general social good I think people may be overestimating their personal risks.

Underlying heath simply seems to play a huge role. In China 10-19 year olds represented 1.2% of the total known cases and 0.9% were 9 or younger. That might have been related to transmission with elderly social circles more widely spreading the disease, or exposure to related diseases etc. However, it’s more likely an indication of untested largely asymptotic cases.

PS: half of the 300 to 400 coronavirus patients treated in intensive care units in Paris were younger than 65

16.8% of the French population is over 65. 50% of their ICU cases are over 65. https://countrymeters.info/en/France That works out to about a 5:1 ratio even including 50-64 year olds at significant risk in the younger population. The avoidance of an age specific breakdown suggests they where aiming to convey a specific message rather than clearly conveying information.

The bare minimum we can do is quarantine for a month until warmer weather arrives. Then we can see if that has an effect.
Oh there's definitely a supply chain issue now; we're not going to be able to re-stock anytime soon is my understanding. So there was absolutely a high degree of unpreparedness at many levels. However, we already nearly depleted our masks and we haven't even had a significant spike in need yet.

If people hadn't been stealing masks for their own personal use outside the hospital, we probably could have had our supplies last another few weeks, which is significant.
definitely raised an eyebrow, first thing I saw and I was like "wow this is gaining consensus on HN?"

If there were really a lot of hidden cases I would have expected a lot more deaths - especially considering Corona mostly affects people in urban areas where hospital access is decent. That being not the case, either there is not too much spread or Indians are somehow immune to most COVID19 effects.

Lidars break. Radars fail. Cameras run into issues. Drive by wire systems malfunction. Computers vibrate to death.

All parts of an autonomous system break. Safety engineering is measuring those breakages, and designing a system that is safe when it inevitably breaks.

If you're the operator, you can choose to only drive on routes that should have sufficient connectivity. If your remote driver is only issuing high level commands (i.e. not responsible for safety) latency starts to stop mattering so much.

The problem here is the availability bias - you've seen your phone fail so you know that telecom links can fail. As a layperson you might not think about how the rest of the system suffers from the same limitations - but they do. You engineer around them.
Yes, I’m saying that the figures on page 10 imply that the blue curve (on its own) is not effective enough to avoid critically overwhelming the hospital system in the UK in the short term.

The guidance towards the measures you see now (nonessential workplace closures, social distancing, restrictions on movement and activity) are what seem to be recommended throughout the rest of the report to suppress the catastrophically high death tolls.

If you read further to Figure 4 (page 12) you’ll see a model for “adaptive triggering” of suppressive techniques (basically staggering to allow a resumption of activity before starting again) which would need to be in place until a vaccine has been successfully verified as safe and inoculation has started.

EDIT:

“Perhaps our most significant conclusion is that _mitigation is unlikely to be feasible_ without emergency surge capacity limits of the UK and US healthcare systems being exceeded many times over. [...]

In addition, even if all patients were able to be treated, we predict there would still be in the order of 250,000 deaths in GB, and 1.1-1.2 million in the US. [...]

We therefore conclude that _epidemic suppression is the only viable strategy_ at the current time.”

Emphasis mine.
This appears to have been quite a thing.
