I’m not sure I agree with the diversity argument. That argument is based on the biological principle of natural selection. However, an economy isn’t a biological system: its a man-made system that is designed and run by an intelligence, actually many intelligent agents working together.

Biology is not designed or run by any intelligent agent that we know of. When people apply the diversity argument to non-biological systems, it makes me think they are actually and really arguing for intelligent design of biology.
Elon Musk plans on refueling his rockets on Mars using locally produced methane. Using solar power, he'll create methane and liquid oxygen from CO2 and water. If he then burns the methane and liquid oxygen in a rocket engine you get your CO2 and water back. Thus the process is carbon neutral.

Before he does it on Mars he'll have to perfect it on Earth first. I hope he does more than that and starts using carbon neutral methane for all his Starship flights on Earth.

It's certainly not the general consensus that the heart is the sole driver of circulation in mammals. Your heart drives the flow of blood out through your arteries; it's much less effective at driving blood back through your veins.
Testing near/at boundary conditions is generally good practice.

A minimal size file could easily catch some cases where your code assumes some sort of structure (some flag, header, metadata structure, etc.) exists when it's possible it actually doesn't.

I'd like to take the opportunity to thank lexi-lambda for multiple thoughtful contributions to the programming community. In the world of open source and software in general there are names that are recognizable - some feel more like "brands," intentionally cultivated, but I don't feel like I'm really being sold something when I see a post/article/wall of text from lexi-lambda, rather through repeated examples I've come to feel a bit of excitement that someone who has gone much deeper down an interesting technical path than I has taken the time to meaningfully share their knowledge and experience for the benefit of others. Thank you.

When I lived in a country without clean water, lettuce, etc was washed in diluted bleach.

You then put the lettuce in a spinner to get most of it off. Then you wait a while for most of the rest to evaporate.

We have clean water so I expect we can use clean water to rinse the bleach off.
People can have older style infotainment systems with fewer to virtually no bugs and significantly less performance or they can have what are essentially computers with much better performance and significantly more bugs.

The trend has been towards better performance at the cost of normalizing bugs, but at some point maybe we will normalize poor performance to minimize bugs.

Why do so few people major in computer science? (2017)
There's three types of muscles: smooth, skeletal, and cardiac. They share a lot in common but are very distinct to each other. Might not be an apples to apples comparison because fatigue is a notion taken from our experience of skeletal muscles which is not cardiac muscle. It would be interesting to compare the energy spend of each, or rather the power each is capable of. As enduring as the heart is its likely limited in its power output because its just circulating fluid against resistance and gravity. I don't know how much energy is required for that. Bench pressing a hundred pounds, what's the power in that and how many heart beats would equal that work?
pandemic logistics?
Bingo, we need nonbiased blinded drug trials otherwise the data could be seriously flawed. There's drug trials for reasons, and even in this pandemic we should respect the rationale for why we established those trials.

Also, I'm finding that this forum is full of incredibly intelligent individuals who demonstrate the a little knowledge is a dangerous thing. It amazes me how often y'all will talk about medicine like you're experts but miss fundamental concepts. May points, like the other poster, sound awesome to lay people, but under the scrutiny of any medical professional would be laughed at.
Significantly, and a large part of the reason why is energy efficiency. Humans have large brains that take a lot of calories to sustain, and because of their large brains didn't have nearly as strong evolutionary pressure to maintain musculature.
The Little Schemer with Racket
The ultimate purpose of the shutdown is to not overwhelm healthcare providers, so people who need treatment actually receive it rather than die waiting in an overcrowded ER. So yes, they would fare better in a shutdown with lessened spread of the virus and fewer people putting strain on healthcare.
Cheating in Computer Science
I get that a heart attack hospitalization is expensive, $55k on average. The physician is not pocketing all of that $55k. They aren't the ones charging that, that is the hospital. The physician will get ~$1k of that (look below for the calculation). Please try to be charitable in your evaluation of my ability to reason here.

I'm not trying to change the topic from office visit to heart attack. I provided the RVU calculation for the outpatient visits. That is how much the physicians are getting paid. You said that physicians are making a couple hundred bucks of each outpatient visit, which I don't believe is accurate, and I provided the calculation of why I don't think that is accurate. The total cost of the visit can be $250, but the physician is not getting anywhere near that.

I don't think it's accurate to say that they will be able clear $1000/hr. There is additional time needed to document each patient (often equal to the amount of time seeing the patient). I think seeing 3 visits in that time is plausible, but the physician is not getting that whole $250 (which is the point I'm trying to make). The clinic revenue may be $750 for that hour, but that needs to cover all of the overhead, and the physician will get whatever is left.

Make sure you are looking for sources that compare how much the private insurance pays physicians compared to medicare in particular vs how much they pay hospitals compared to medicare. The numbers will be different.

The $53,384 is what the hospital charges for the heart attack. The physician only gets the wRVUs for the services they provide in the hospital (if they're employed), so the 12.56 wRVU for the cardiac revascularization + the admission history and physical (2.61 wRVU CPT 99222) however many days of progress notes (2.00 wRV 1x each day - CPT 99233) in the hospital and the discharge summary (1.28 wRVU - CPT 99238) they write for the patient. So if a patient got revascularized and were in the hospital for 4 days before being discharged that's 12.56 + 2.61 (admission day) + 2 * 2.00 (2 inpatient days) + 1.28 (discharge day) = 20.45 wRVUs for the admission = $737 for the physician for that hospitalization.

I'm trying to make the distinction here between how much the hospital gets paid vs. the physician who provided the care. It's not accurate to say the physician is making $53,384 for the heart attack hospitalization, that is what the hospital is charging. The physician may make ~$1000 for an admission like that. If the physician is self-employed or in a group, they will charge for the facility RVUs and malpractice RVUs as well, because they need to cover the overhead of having a clinic to see the patient after the hospitalization.

If your bill breaks down the overhead for the clinic separate from the physician charge, then I'll agree that the physician made the $250 straight cash, but I don't think that is in any way the average amount any kind of doctor will make off an outpatient visit. Look at what you're suggesting, that a physician makes $1000/hr * 2080 workable hours in a year (not likely a physician only works 40hrs a week..) = $2+ million a year.
The only generally applicable information form the paper is the viral half-life in aerosols/on surfaces and comparing it to SARS-COV1.

This won't help in determining how long to quarantine packages unless someone finds out what the typical viral transfer is e.g. when sneezing or when handling a package with contaminated hands - and how many/few viral particles "ingested" may cause an infection.

I don't think one can simply conclude at all that "viruses will survive X days on cardboard/steel/plastic" because viral particles go through an exponential decay in the environment -- so more particles == more time to inactivate all the viruses, and the reverse.

As far as I understand it, there's no predetermined "viable lifetime" (a sort of biologic clock and death) of a virus, the environment will just eventually destroy it and that point seems essentially random for an individual viral particle with different probability distributions on different surfaces.

So if you start with a viral load that is higher, you will be able to detect viable viruses longer.

So these numbers, e.g. detectable for 3 hours in aerosol don't mean anything unless the average human sneeze excretes as many viral particles as a "3-jet Collison nebulizer". If we excrete more than more viral particles remain viable longer and the detection threshold is reached later. If less, than those 3 hours don't apply.

i have always wondered if society could get something useful out of gaming other than entertainment (not saying entertainment isn't good or not useful). gamers seem to have this uncanny ability to focus in on a game for hundreds, if not thousands, of hours, becoming skilled well beyond any of the developers' dreams. even when i was younger i could poor hours into games like that. it's pretty amazing, because i don't really feel like i see as many people doing that for other things.

This is the best book review that I've ever read. Or at least, the funniest. And perhaps the most honest.
> You're basically saying, a) should we care less today and let the virus spread more? OR b) should we care less in the future and let the poor bastards dope themselves to death?

I think this is a really callous way of putting it, and it's only valid if you accede to the empathetic framing. The point of my original comment is to show that there is an econometric argument against the empathetic framing, even for one intended to allow empathy to dictate their opinion.

> I feel like half of your problems listed are solved by hiring more therapists and psychiatrists.

Part of any rational decision process asks about the costs of the different options. The cost of this economic recession will be high; the cost of improving mental health infrastructure would have been much lower.

> Perhaps the solution is: Save as many people as you can today then, and when there is an economic downturn we should do a better job helping people get off drugs by talking to them and treating them, helping develop new markets, reaching out to young poor communities.

Why decide to pay both costs when only one needed to be paid?
Making a 2D rasterizer is fairly trivial, making a rasterizer that looks good is insanely difficult. Handling things like aliasing without overblowing and making it work in all possible cases is tricky and one spends 99% of time addressing those tiny little details that "make one fall in love with software".
It doesn't because it can't. Any hearts that got tired died, and their owners did not reproduce.

It's like being Atlas--you're holding up the world. It's not a virtue, a flaw, a conceit, nor anything at all. It is because it must be.
> Right now, as I type this, many hospitals in the United States have had all of their excess intensive care capacity used up by Covid-19 cases. Not all, but many.

Do you happen to have a source for this? I haven't heard much about hospital problems yet.
For me cash isn't so much about privacy (though that's nice) as about control. When you use a credit card or the like you are having a large impersonal corporation that has historically been influenced by both state actors and public opinion deciding who you can enter into transactions with.

It's a long leash but it's still a leash.
Muscle cells don't replicate past early childhood development, they just get bigger and add more nuclei. So muscle cancers are extremely rare compared to cancers of other tissues.

Why though? I find buying one $30 dongle that has 10 inputs for cables I already own is a better deal than buying 10 $20 usbc cables. As a mac user I've been used to dongles for a while, mac laptops never seemed to have the standard AV out aside from that fluke generation with HDMI. Always some weird connector for the sake of being weird, it seemed.
The concept that helped me most understand my own body was realizing the signal and the system are separate. In your car, the oil light is almost entirely separate from the actual oil system.

It's the same with our body. Feeling tired is separate from being tired. Feeling hungry is separate from being hungry.

Drugs work like putting electrical tape over a low oil light. Amphetamines and even caffeine are good at blocking out the signal. The underlying issue is still there.

But, sort of like you said, the signal comes really early. It's like a low fuel light that comes on when you get to a half tank.
If the business is providing no services or products, then it cannot afford to pay its employees. This is because the economy is built around mutually beneficial exchange, which only happens when people can work.

Example: I go to a clothing store and give them an amount of money that I value less than the clothes they give me in exchange. We are both better off because we have made that mutually-beneficial exchange. If the exchange doesn't happen because the store is closed, then there is no revenue (let alone profit) to divvy up.

The only way to simulate that transaction in a way that gives money to employees is to literally take it from customers who receive nothing in return.
Yeah, I’ve never understood why companies aren’t doing this. Not commingling inventory seems like an easy fix to the increasingly widespread fraud issue.
I wrote a perl script to automate signing up for and downloading the bar code image for my local grocer's discount card without actually giving any name or information. I just print out a new one every month or so.

New employees occasionally get confused by the lack of a name but it's never a problem. I pay in cash, of course.
The 'economic system' is based on fundamentally one thing: people doing stuff. If people can't do stuff, literally, like go out of their houses, then no new economic model can work. It's like, the one requirement for everything.
> it's just the same curves at smaller scales.

It's not that simple unfortunately. Hinting for TrueType fonts is a thing and without properly aligning resulting pixels at their own scale fonts tend to look very ugly when following pure curve definitions. Oversampling at e.g. 8x size is one possible option but then there are other problems that pop up once downscaling to display size.
I've done time in state and federal prisons. While I've never been without soap or water or been in an overcrowded facility, the medical care is very bad.

At an older federal prison, we had to check shoes in the morning for brown recluse spiders. One guy got bit on his foot by one of them and it quickly turned black and blue. He went to medical and they diagnosed him as having a fracture, and set a cast on his foot without doing an x-ray (which would have meant a trip out to a hospital).

Several weeks later they had to amputate his leg below the knee.
> The old landline to landline calls had no more delay than talking to someone in person.

Depends. They had such awful sound quality that they could induce delay while you tried to understand what the other person had said.
This resonates with my understanding: evolution is lazy, not optimal.

Or: evolution is lazily optimising. Survival doesn’t imply perfection, as it is my definition a process.

And the more optimised an organism is the more fragile it’s continued existence.

you don't buy what? they didn't say what you imply.

they didn't say the drivers didn't need skill and only need money. they only said money was an additional and the larger barrier to entry. of course they need skill, but you'll never know if you have skill or not if you don't have money. nearly any type of racing is incredibly expensive.
I realize that the FDA serves a purpose, but in dire situations I think anyone should be able to take any drug if they sign a document stating they will hold no one liable for adverse affects of a drug that might have chance of saving their lives. Why does one have to follow the state's one-size-fits-all rules when their life is at stake and any potential harm is limited to themselves?

My point about relocation is a lot of people relocate for jobs that they could easily do at home or in a satellite office. I get that some people want to move so they aren't stuck in the same town of pop. 1,200 all their life (that's my situation), but I don't think most people are in that situation.

Say you were raised in Wichita, KS. I've never been there, but given its size I assume you can have a pretty good lifestyle living there. However if you want to work in tech, media, journalism, law, finance or a whole bunch of other industries, you would really be limiting your opportunities if you stayed there.
Hypertension, diabetes, obesity? Aren't these all costs of eating terribly?
Why didn't you respond to the actual point? What do you think is going to happen to people with chronic health conditions in a depression, or when supply chains stop functioning? What happens when (random example) e.g. anti-HIV medicine shipments can't be made and we start to get new mutations in those diseases?

Do you just assume we'll treat chronic health issues as a priority in a depression? I'd like to think we do as well, but the point is that things may well just stop working.
each nucleus contains a full genomic content.
muscles are more of a "myosynsynctium" than a group of cells.
there are cohorts of cells that are more prone to becoming cancer due to thier developmental origins and the complement of developmental mechanisms that can be reactivated.

things such as cell adhesion, and cell migration through tissue dermal cells are good at this as they do these things over the course of development.

muscles are built where they will live so these features are inhibited somewhat more completely and harder to "switch on or off"
I just want to stress this again!

I see so many people claiming that you need to quarantine your packages for X days to be safe - this does not seem to be what the study says!

That doesn't seem to be true unless the number of particles they spread on the surfaces is representative of someone handling a package with contaminated hands.

Viral particles seem to decay exponentially with a specific half-life (the environment just seems to break them down/inactivate and it's essentially a random process). So if you start with many more viral particles than this study, then more infectious viral particles will be on the surface after a set amount of time. Viruses do not seem to be like cells with a specific "life-time".

This study essentially shows that this virus behaves a lot like SARS-CoV-1 but spreads more aggressively - it must be something other than longer viability on surfaces/aerosols.

I am hopeful that it comes back through-the-glass in the next iPhone. I was perfectly happy with it on my last iPhone, and there are times (tabletop) where it is better than Face ID.

I tested a few of these in store, and at low heights they were fine, but when raised they were really wobbly. I've used standing desks that wobble when you type, so the monitor wobbles, and it's really distracting to work like that.
