> You still keep it all in your head, but the compiler errors protect you from small mistakes.

It is interesting how "protecting from small mistakes" is touted as "solving our API woes", innit?

At some point it is liberating to admit that static vs dynamic is a matter of personal preference and nothing more. If I like it, I will find a thousand reasons to justify it, and vice versa.

I just wish everybody would be open about it: I like "type safety" and the warm fuzzy feeling it gives me, and nothing you unwashed heathens can say about tight coupling, increased incidental complexity, over-engineered APIs and productivity loss can sway my opinion! Why, my productivity is _increased_ with static typing, because I make up for hours of bikeshedding about which type better conveys the underlying intent with writing less null checks and unit tests! Take that, type haters!

Meh, wishful thinking.
Yes. Thank you so much for saying this. It seems like there is only a handful of people who are trying to keep the focus on the truth in the midst of this partisan battle of competing narratives.
Oh those 5G conspiracy theories are now an inch less crazy..still crazy but contact tracing is indeed big brother. Though for now it's only opt in until there's an outbreak in a city or state then the government will recommend then mandate it in those areas. Then as time goes on it becomes the norm and the majority are fine with being monitored and watched by the government. Public health vs. human rights/privacy.

There was a depression in 1920/21. Of course, there were multiple factors that led to that not the least of which were lots of soldiers returning from WWI.

Also, lots of people worked from home in 1918. 40% of people lived on farms in 1900 so probably not much change from that by 1918.

The cpu just takes a bunch of numbers and applies the same operation on them in one instruction instead of a bunch single ones. E.g. if you are writing some simulations/game code where you deal with 3d vectors a lot the use case is there a lot. Is it worth writing the custom instruction intrinsics yourself? Most likely no as the compiler often (!) does a good job at auto vectorizing or the underlying library already uses them (I think c# vector types does).
TLDR:

"Stanford researchers are looking into the possibility that coronavirus first hit California undetected last year, much earlier than anyone realized, and was only seen at that time as a particularly nasty and early flu season.

As a result, the theory says, many Californians have already unknowingly been exposed to the coronavirus and have developed immunity to it.

To investigate that idea, researchers are testing people for antibodies that indicate a previously undiagnosed infection that was defeated by the body's immune system.

The Stanford researchers tested 3,200 volunteers at three testing sites in the Bay Area. They are expected to publish the conclusions of their study in several weeks."
Can anyone offer an LCD alternative?
I doubt people alter their behavior for long. Certainly not more than 6 months after the crest is over.

The 1957 flu pandemic killed 100,000 Americans, which adjusted for population is where current models estimate Covid will land. And it had virtually zero lasting impact on culture of behavior.

Keep in mind that basically nobody else uses the word "crash" to mean "goes to zero and stays there". Traditional economy is generally a reference to the act of exchanging money for goods and services.

You can use words however you want, but if you want to be understood it's helpful to use the common definition.
You've called people rude for feeling strongly about their objections to this change, you've denied that Mozilla would have shipped a negative change, you've accused the detractors of this change of not understanding that it could pose a maintenance burden to keep it optional, and you've asserted that said maintenance burden outweighs the usability benefit of letting existing users keep the existing behavior.

You've done everything except provide an actual argument in favor of why Mozilla should introduce this new UI behavior that breaks existing conventions and interferes with other features in ways that are as-yet unresolved.

And you're doing similar stuff elsewhere in the thread about other questionable Mozilla UI decisions.

> Leaving the entire population with lasting immunity

Based on what we know, I don't see how you could carve a large enough population group out where you have < 1/300 chance of death and < 1/50 chance of being hospitalized. Your timeline is realistically years to not overrun hospitals, if this is even an acceptable death rate [which it won't be in developed countries]
> We have to allow these enterprises to fail and have their equity be wiped out to have a functioning capitalist economy.

That is utterly absurd.

COVID-19 isn't the fault of an airline or hotel company. There is zero reason these enterprises need to fail, any more than your local restaurant ought to go out of business and be replaced by another in a few months.

And people's savings for retirement aren't part of any "program". They're spread over all sorts of investments. Trying to let corporations go bankrupt yet somehow "make up the different" in a fair way to individuals would be convoluted and frankly impossible.

So no. Punishing corporations is the wrong target. Corporations aren't rich people. Keep the corporations going together with the corner restaurant... and tax the rich.

Seeing COVID-19 as some kind of solution to economic inequality is dangerous confusion, and frankly bizarre. You want to lessen inequality? Bankrupting companies is one of the absolute dumbest ways to do it. Just tax the rich directly. Institute a wealth tax. It's simple, targeted, effective, and doesn't have the horrible side effects that bankrupting major corporations has.
You can! Right now you can upload a PDF and that becomes your story.
1. It's old people AND people with comorbidities, which is a ton of people.

Yep, and they should shelter in place. Nobody else should.

2. Lots of old people, which for Covid is about 65, still work full time jobs. Some of them fly every week. These aren't 95+ year olds.

Yep, and they should shelter in place, because they're in a risk category.

3. I'm sure people of all ages think their life is very valuable, and very few people consider themselves candidates for sacrifice. Certainly not for privacy concerns.

That's an unfortunate way of looking at this. The reality is everything we do in life involves risk. There's risk of harm in shutting down the economy, and there's risk of harm in opening the doors. The lifetime risk of death being involved in a car accident is 1%. The lifetime risk of dying of an opioid overdose is 2%. COVID is much lower than both. Locked inside domestic violence is up, alcoholism is up -- liquor stores are considered essential so alcoholics won't come in to hospital due to withdrawal.

What we do know is if we lock things down, then one person flies in from a foreign country with the disease the whole thing starts over. Hiding inside is not a sustainable strategy.

Which is why Sweden remains open for business. And you know what? They're doing just fine [1].

4. 10x deadlier than the flu.

It is not. We do not know how deadly it is, all we know is that of people who go to the hospital (implying that they're showing serious symptoms) between 0% and 9% of people, depending on their age and comorbidities, die.

That's adverse selection sampling bias. Studies show there's huge, huge quantities of people who either show no symptoms at all (which is the thing that makes this disease a challenge) or exhibit mild flu-like symptoms.

The numbers we're seeing are an upper-bound, by an order of magnitude. It's likely in line with the flu, although we should consider in line with the flu is bad -- it kills 650,000 people each and every year we've been alive.

It's also much harder to immunize against the flu (19-60% effective) due to its propensity to mutate and the huge number of strains that show up each season, with different ones being dominant each year.

On the other hand, COVID does not mutate -- or has not yet.

Very true. I retired early (around 50) and not having enough money to be a world globetrotter I found things boring around my town. So I started working again (2x) 4 times per week and that helped a lot.

I agree that older workers not in specific high needs businesses are seen as low wage cogs.

Funny but I live in a town with a lot of people who've retired and so even volunteering is difficult - there's a glut of volunteers. Now with Covid stay at home almost all volunteer opportunities have dried up.
It's sickening how all of these lifetime senators and congressmen can amass such wealth given the salaries of their elected positions.
4. And there's no preexisting immunity, unlike with the seasonal flu. Left unchecked, CoVID-19 will infect a much larger share of the population than flu.
But the current majority, at least in the Senate, seems not to need to care about the appearance of impropriety.
You can actually do that fairly easily, just add the parameters linked to a second boot entry in GRUB.

However, I would very much not advise doing so, as I still am unaware of any task that can both, be done without the need for a network connection, while also being significantly slowed down by the mitigations, after recent improvements to the kernel and software. Basically, the potential benefit is very low in a lot of tasks, whilst requiring additional security measures (ideally fully air-gapped) and that you reboot the system every time you'd do such a task.

Also note that, in theory, just being temporarily offline may not shield from being exploited fully.
TL/DR: Treatment before intubation.

With the DP3T derivable day keys, you could identify that you were actually in contact with the same infected person multiple days.

If the server ships 14 * (# of people infected) every day to every user, instead of just (# of people infected) and have the client generate the 14 keys for each infected person, you would only be able to identify that you were in contact with an infected person. With the DP3T proposal, it looks like you can identify that you were around the same infected user multiple days, which might be slightly worse for privacy (in the sense that it would help you identify who you got it from).

But in either case, because the secret key is reset after being made public, it would not help you identify who was previously infected.

5g, I have heard, allows more fine-grained positioning.
If you were to deliberately go and hangout with someone you know is infected with the attenuated strain then a lot, if you catch it because your neighbour did this then none.

This discussion is really a distraction as I don’t think a “grass roots” spread would be the way any such strain would be spread. I think the regulatory agencies would look at the data collected from the natural spread and use this to approve the strain for use.

Turbines have great power to weight ratios but very poor efficiency at low loads (cruising on the highway is a low load). GM actually seriously considered this along with Chrysler and it was abandoned due to the oil crises.

> General Motors at one time manufactured a bus powered by a gas turbine, but due to rise of crude oil prices in the 1970s this concept was abandoned. Rover, Chrysler, and Toyota also built prototypes of turbine powered cars, Chrysler building a short prototype series of them for real-world evaluation. Driving comfort was good, but overall economy lacked due to reasons mentioned above.

That's not actually true. The seasonal flu affects 45,000,000 americans every year, and in part because it (a) mutates and (b) there's a huge number of strains, and different ones are dominant in different years. The flu shot is not particularly effective for those reasons (19-60% depending on the year).

COVID however, does not mutate, or has not yet. This means herd immunity is on the table, and so is a ~100% reliable vaccine -- like MMR, not like flu shot.
> Yeah exactly, I think of this as "imperative in the small" and "functional in the large". There's no real cost to local state, but there's a big cost to tracking global state.

I think of it as having to deal with the fact that humans only have so much mental space/short term memory.

The problem with stateful everything is that you can't build a complete understanding of it; there's just too much. However, for short bits of code that don't leak their imperativeness to the outside world, it doesn't matter. You can read the whole function and understand it.
> Q: Wouldn't this list be insanely long? More so if it doesn't have any concept of location?

I don't think such a list would be that long:

1. It's not unreasonable to have some approximate concept of location (e.g. "New York City and surroundings")

2. A contract tracing app is only useful when the number of new infections is low enough, such that all possible contacts can be tested.

3. For a tracing key 32 bytes would suffice. Even for 15,000 relevant infections you're only looking at 0.5 MB of data.
This is an amazing line- I think it transcends fields.

The Russians claim to have made such a system. They also claim nuclear powered torpedoes. It is not 100% clear how far they really are. However, there was detectable accidents, so they are at least really trying. It ain't all bluff.
What is the significance of the distinction?
So I am no expert and I am not the commentor you replied to but...

I thought the idea behind PetroDollar was that countries sold their oil, that gave them big trade surpluses, then they used that to buy US Government Bonds. They chose US government bonds because they are secure, inflation proof, liquid and it gives them geopolitical clout.

The fact that many oil transactions are priced in USD isn't really relevant because if you get paid in Euro\Yuan\Rubble and immediately turn them into USD, then USD is where the demand will actually be. As OPEC members all wanted dollars because that's what you use to by US Govt Securities, that makes the USD the "petrodollar", even if they all insisted on being paid in say Euros and then sold those euros to buy USD it would make no difference.

So that answers why it doesn't really matter what currency oil transactions happen in.

But it represents another problem for the PetroDollar hypothesis: Who is buying US government debt and how much are they buying (net). Because that is where the real strength is, people want US bonds, not US Dollars.

When all this started, there were few countries with long term surpluses, just Opec really. But since then Japan and China (Japan apparently holds more than China as of 2020 I think, but the link says the reverse as of 2017) has eclipsed them. Saudi are minor holders actually, other Opec holders not even making the top 20.

https://en.wikipedia.org/wiki/United_States_Treasury_securit...

Also, oil prices for the last 20+ years have been very unstable. At times (Iraq wars, the 2008 crash etc) the oil price has been high and that means Opec have a lot of cash to purchase bonds. But at other times (like now) the oil price has been low. Right now, Saudi has a trade deficit. So they are SELLING their US securities to fund that. Also, the slow erosion of market share of Opec has meant that even high prices are no longer as big a revenue boon for them.

Similarly, China has become a much bigger purchaser of bonds. That sort of works in favour of the "petrodollar" (should it be petro\sino\japan dollar now?) hypothesis as it makes it easier for the US to run a government deficit. But right now, China is coming out of quarantine so their economic numbers are about to stall right?

So if the Saudis (and Opec) can't afford US bonds and the Chinese and Japanese are not buying them (as their economies stall), just how interest rate resistant is the US deficit? I suspect people know that the treasury will print dollars to maintain the deficit as they have been since 2008. But that only happens without inflation when everyone else (Brits, Eurozone etc) are doing it too. But if they manage Covid-19 better than the US (and respectfully that doesn't seem hard), they wont need the same deficit funding. And similarly EU social structures mean they can deal with disasters like this without the use of central government funds.

So really is this a case of Who Knows what will happen?

I think there are absolute negative effects to just about every change because of reasons like invalidating muscle memory, unintended consequences, documentation synchronisation, config options, and the chance of introducing bugs. If one cares about certain things a lot, these effects may be larger than developers expected. For example, if you are blind, user interface changes may suck a lot more than for sighted people.

Changes can still have net positive effects, however.

Any solution to this problem needs to consider that its not just about getting work done. It's getting the right work done to satisfy the needs of society. Money acts fairly well as a feedback mechanism, because if the work you're doing isn't useful to someone else (or at least believed by them to be useful), you won't get paid to do it.

For example, If I'm feeling generous I might be willing to cut the grass of an elderly neighbor or volunteer to repaint some rooms in a local school. On the other hand, I'm not going to spend thousands of hours learning a trade plus tens of thousands on equipment, licensing, etc so I can build a school or build my neighbor a house for free.

Jobs consist of some mix of fun work and drudge work. If I'm not getting compensated, even if I do need some small amount of work in my life, why wouldn't I focus on the fun work (e.g. writing new software) and skip the drudge work (e.g. software testing, maintenance, planning, work tracking, documentation)?

Also, I'd like to say I've always felt that my jobs took up too much of my time. Even if I decide that some work in my life is valuable, it might be at a much lower level than would benefit society (e.g. 8 hours per week vs. 40 hours per week). Average that over a whole society and that's a lot less getting done.
I actually do address the numbers needed in the post. Yes you would want to sample as widely as possible in the ideal world, but more important is just getting the right samples.

The reason why this would be faster is the process of looking for the strain and identifying it as safe would generate data that would allow the regulatory authorities to approve its use.

Manufacturing would not be the limiting factor here.
