A lot of the links you provide have alarmist titles and big claims and confusing evidence. Which is strange since the twitter authors are clearly well educated virologists/epidemiologists. But the style of language makes it difficult for me to trust what they are saying. So far I am sticking to research papers and This Week In Virology [0], where there is a lot less dramatic clickbait language and a lot more skeptical analysis of statistics. My conclusion so far is that no one knows how this will play out, but the fear seems to be more dangerous than the actual disease in many places.

That is counter to nearly everything I've read from equally intelligent, cautious, subject matter experts over the past couple days.
I'm not even sure that the movies underperforming is that significant. The are making boatloads with merchandise, and with every new movie they've introduced at least one new cute character that everyone seems to gobble up (BB8, the mini-peguin-like thing, now baby-yoda). They've also opened up Galaxy's Edge at one of their parks which brings in a lot of visitors.

Yes, they had to relax their movie timeline a little bit, but they're operating Star Wars close to their monetizable limit.
There is a non-negotiable entropy cost associated with removing CO2 from the atmosphere: you need to either pump it, so P0 = 0.0004 atm; if P1 = 5 atm (liquid CO2) then E = M R T ln(5 / 0.0004) / 44 => E/M = about 500 J/kg, or you need to absorb it chemically, which requires a chemical with a vapor pressure of CO2 < 0.0004 atm, (e.g. NaOH) itself generally energy-intensive to produce.

I expect that we will eventually develop technology for CO2 extraction, but it's not going to be easy or convenient. 500 joules per kilogram is a lot and I doubt chemical methods will beat it. Currently there are about 3.5 trillion tonnes of CO2 in the atmosphere, or about 3.5 * 10^15 kg. To decrease the concentration by 1/3, returning us to preindustrial CO2 levels, you'd need about 600 petajoules or 170 terawatt-hours of input energy assuming thermodynamically perfect isothermal compression (which is impossible to actually achieve). Global world electricity consumption per year is about 21000 TWh.

No current method of CO2 extraction comes close to this limit and it's very unlikely that any ever will. Nonetheless, we have several orders of magnitude of wiggle room to let real-life methods work out okay. But the energy cost is not small and the negative effects of present-day CO2 emissions should not be considered easily curable.

And just for the fun of it, a human being releases about 4 * 10^5 kg of CO2 during their lifetime, requiring about 2 * 10^8 J. So the most efficient CO2 pump possible would require at least 200 million watts of power (about a thousand Tesla Roadsters at maximum output) to confine this CO2 within a second.

Drug interactions are basically the perfect type of thing to automate. It's just a lookup.

For usage questions, how many parameters does that vary on? Amount, frequency symptomm? Seems very easy to automate as well.

The only thing not able to be automated is law abidance. This would require changing of the law.
Not accurate. Deep approaches work better.

Indeed, if you control over DNS you have to advertise your own DNS server than blocking outgoing DNS requests for everything except you nameserver (UDP and TCP).

I know a guy who went to work as a post-doc at Harvard. He left behind experimental samples of human blood that were unlabelled, which I had to inform his former supervisor about. He also had a number of other professional failings. The takeaway is that just because someone has "Harvard" on their resume doesn't mean they are even remotely competent.
If you can capture the CO2 using transient power from wind or solar and use it to make a synthetic fuel, then you have a potentially viable option. Carbon Engineering in Squamish BC is doing this for $100 a tonne. Their synthetic fuel costs about $2/L to make - still too expensive, but not if the carbon price rises to about $100/T.
> As important as health is, and as much as Americans spend on it, it is shocking to me how gated everything is.

Agreed I had this issue as an uninsured university student with an Xray, and as one covered by my employer's insurance with an MRI.

In both cases I was stone walled to just get either, in the former I had to go to a clinic see an MD, come back get a physical and then get a referral for imaging off-site. And in the latter, I had to see 3 specialists, get a physical, have several weeks of Physical therapy and Xray imaging before the Insurance would cover it.

> Again, I pay for health insurance, but I still feel like if I want a quick EKG, it will take me 3 weeks to see a doctor, and by then I might be dead.

It was so exhausting just trying to make all the appointments and follow ups with a full work schedule that I haven't been able to get that MRI after all. I just assumed the worst and started to take matters into my own hands and started to do my PT exercises into my daily gym routine and will monitor the results myself.

> What am I missing? Are there legitimate safety reasons these mundane diagnostics are so locked down?

Its a protected Industry, the very supply of MDs is drastically capped in this country, its a controlled cartel.

There's nothing nonsensical about it. That's a very poor analogy as well, comparing a startup's growth to the spread of a highly-infectious virus.

COVID19 spreads by default. If you leave it alone, it will spread uncontrollably. China went from 0 to 79,000 confirmed cases in 2 months, despite running the largest and most extensive quarantine in human history. If there was no quarantine, you could expect truly exponentially higher number of infections.

The problem with these things is, if the rate of spread is >1, then it becomes exponential. That is, if the average person infects more than one person, then the rate of spread is going to get completely out of control. Unless of course, you can impose measures that reduce the rate of spread to below 1.

With coronavirus, it's not possible to do this. The reason is that many people are asymptomatic for weeks, while at the same time passing the virus to other people. If you cannot identify infections before they have the chance to spread at a rate of >1, then the spread of the disease will by default be exponential.

A startup does not grow exponentially by default. Many actions need to be done correctly to continue growing. A business's default state is death.
> We kill people because it's "what they deserve," as if the state has any right to decide whether its own citizens live or die.

Sounds about right.

True justice is to undo the damage caused by the perpetrator. Unfortunately, it's impossible to do that. There's no way to restore a murdered person back to life or restore people's ability to feel safe in their own homes after it's been violated. Some damage always remains and it just can't be completely fixed.

So it's all about revenge, making people pay for what they've done and causing just as much if not more damage in return. For some reason, people can't just accept that things happened and that there's no fix. There must be balance in the universe and they can't move on with their lives if something isn't done to the people who hurt them. So we have judges, people who literally count infractions and calculate punishment. People who perpetrate sanctioned violence.
> The lessen for an average here is, imo, is give to homeless people but don't give more on a sob story, don't give only to a sob story.

My solution has become to give food if I want to give something.

Unless they are honestly trying to sell something legally or perform music or something (I really have a soft spot for anyone actually trying to work):

- If someone plays music I might once in a while give something along the lines of $5-10 if it isn't too bad. It actually brightens my day to walk by someone playing.

- Recently I also bought a magazine from a friendly old chap. I don't know how common this is elsewhere but in Oslo severely disadvantaged people can apply for jobs as salespeople for "=Oslo" which is a monthly magazine that is only sold by people like them. Based on my first impression (this months edition) I might very well buy again. The price is 100NOK which translates to just above $10 and for that price I got some actual journalism and I get to support a person who is in a rough spot but actually want to work.
There’s a WIP pull request for it, so it should be here soon.
> There is no magic powder we can mix that'll cause CO2 to precipitate out of the atmosphere and fall to the ground like snow; it's a grueling energy intensive process to filter that out of the air around us.

Why not to cool down air so that CO2 would fall off? Cooled air can be used for pre-cooling incoming "dirty" air stream?

The biggest impact will be on global supply chains. Also paints into sharp contrast our over reliance on China.

A side project I'm working on uses a key component from a Chinese manufacturer. Their factory has been shut indefinitely and we are 40 days behind schedule. My rep told me that while they've been working on the marketing/tech side of things from home, the factory can't open since workers are simply refusing to show up, and neither coercion or incentives seem to help.

> That’s why I believe that Australia and the southern hemisphere will not see any great infections rates because they have lots of sunlight and they are in the middle of summer. And Wuhan and Beijing is still cold which is why there’s high infection rates.

Wouldn't Singapore already have shown this by now? They've had to devote considerable effort towards management and it's basically summer year-round there and it's quite humid..

Winter also means people wear gloves, touch their face less, and don't sweat as much.
Research data tends to trump personal anecdotes, both yours and mine included. Several separate studies on the homeless have consensus.

I did not say I was part of the “good homeless”. What I said was that the vast majority of the homeless aren’t chronically homeless and I was part of that non-chronic population. I’m also saying that for the chronically homeless, homelessness is just the symptom of the underlying problem of mental illness. This is another way of saying, “they didn’t get the right kind of help that they needed”. When people still can’t be high functioning with all the social safety nets available, we have to re-examine the strategy that isn’t working for them. I don’t feel the half measures you’ve described is enough for the mentally ill

We’ve had this discussion before months ago. We can just agree to disagree.
Vaccines can involve a number of techniques that can provoke a stronger immune response than a natural infection.

>1st party ads aren't blocked. So if that developer wanted to monetize with ads, they're totally free to do so.

They're only free to do so in Brave's eyes if they roll their own ad solution, which is an option but not _always_ the best option. The "easy" (and, arguably, more featureful/secure/"better") route to monetize across the Internet (especially on hobby projects and small businesses) is third-party ads. There's lots of reasons someone might weigh the options and make the decision to go with a third party ad provider; Brave takes that decision away. Whether that's better or worse for the Internet as a whole is debatable.
We also have to keep in mind that that 2% rate is in a fairly developed country with robust medical infrastructure and a decently young population.

You can't expect the same death rate in a country with poor medical infrastructure (say, Afghanistan) or an old and vulnerable population (say, Japan)

If this thing truly hits the predicted scale, even good medical infrastructure won't help if it is stretched too thin.
At a nearly 2% mortality rate even for younger people, I think the odds are high enough to be worried. It's obviously not as deadly as the bubonic plague, but this disease is very infectious...
Fujifilm X-T4 announced with in-body image stabilization and flip-out screen
As much as I hate to say it like this, a pandemic is only going to kill something like 5% of the population at the top end. The Spanish flu in 1918 infected 500 million people, which was 27% of the population (according to Wikipedia). The death toll was about 40-50 million (possibly up to 100 million at worst). It was one of the most deadly worldwide infections in the history of the world, but probably killed less than 3% of the population.

A pandemic is going to severely hurt the economy, but it won't completely stop it. It will not be the case that nothing will be produced for months on end. People will go to work. Farmers will produce food. There will be shops. But things will also be in short supply. Prices will probably rise. Poor people will be hit harder and there will probably be some famine (or at least more than there is now). But things will still continue.

In an event like an earthquake, entire distribution lines are shut down because you can't physically get somewhere. With a pandemic, things will be in short supply because labour is in short supply.

Basically the programs to "offset your footprint" don't scale.

They do not address the fundamental causes of emissions which are steadily growing.

They have some merits for mitigation of the problem but not as a long-term solution
It's not 2% for younger, it's like <0.5% for less than 40, and something like 10% for older than 70.
Seems worse than the average flu. Not likely that you'll die from it if you're young and not immunocompromised, but just because you don't die doesn't mean there won't be long term health effects. And if you have anyone over age 70 or under age 2 who you care at all about, their lives could be at risk.
"Energy balance" isn't the right diagnosis because the energy balance has not changed significantly: the sun is and has forever been the dominant energy source in climate terms.

Broad-spectrum sunlight hits the earth, and is later emitted as infrared. CO2 is transparent to UV, but absorbs infrared. So global warming is a consequence of the fact that the major fossil fuel emission is opaque to a wavelength of light emitted by the sunlit earth.

"Letting less enter", "stored the excess energy", and "reflected some fraction" are all huge engineering solutions to the global warming crisis. And I support them all! But space mirrors and geo-scale energy sinks are sci-fi, they will not save us any time soon.

Reducing consumption buys time. Switching to renewables buys time too. Maybe you use renewable biofuels and capture the CO2 emissions: now your car is carbon negative, without launching a space mirror!

I think many people here on hackernews are being stupid that they are healthy adults so they don't need to worry. Even if you don't die you will be out of the work force for 2-3 weeks either because you are sick or quarantined. You could pass the infection to your children, parents Grand parents who might not be able to fight off the infection and die. Many people get flu vaccines or over the years have built up some immunity. This virus is new so no one has any immunity most people will get infected only some might die but the many that get sick will be out of the work force. You guys are aware of tech productions shortages but a lot of other goods like garments we wear come from China. If they are unable to start back up soon world will be facing shortages of many other items prices will start going up soon. Other countries have started hitting capacity production for garments as China is out and they still can't meet the demand.
It only has to do it cheaply now because there is NO COST to putting CO2 into the air.

Why are people surprised that if something is free (pumping CO2 into air) demand for it is high?

You are telling me that doing a charge of let's say $10 - $100/ton of CO2 wouldn't have a DRAMATIC impact on emissions? Is $10 - $100/ton too little for a supposed climate emergency?

There is so much funding and lawmaking and finger pointing and shaming - but still - dumping CO2 into the atmosphere if free and dumping remains high and people pretend to be surprised.

On energy: CA curtails (turns off) solar (and wind) power because there is not enough demand. In 2019 CA had 921,000 MWhs of curtailment.

Let's start by charging something for CO2 emissions.
I think it is a case of treating the job like a job. You do a solid days work then go home. Don't worry if you didn't do it as well as the next guy or girl. There are people that know a lot of stuff, and HN in aggregate knows a hellova lot of stuff, but the main concern in a job is being productive, being able to find solutions to their problems. I think an occasional course to refresh on something is fine, but there is no pressure to code at home. There are plenty of people doing valuable work using the C# or python or php skills they have been using for years. Many systems will use frameworks from the 2000s.

> If they want Star Wars to reach similar success, then they need to build a loyal fan base an order of magnitude larger, of which traditional fans make up only a small amount.

That's exactly what they were trying to do, yes. Not just sell a bunch of tickets to people that will watch whatever popcorn flick is showing, but to create and expand a new, young, dedicated fanbase. The problem is, it doesn't seem to have worked. :)

(Some of the most rabid Star Wars fan I know are in their early 20s, were nuts about Star Wars, loved TFA, loved Rogue one, but have been steadily growing cooler as the Disney trilogy advanced. And every time Disney changed course to make one group happy, another got even more outraged, until eventually everyone was upset. I know people who saw TFA in theatres several times, TLJ twice, and then ended up not buying a ticket for TRoS. Anecdotal, of course, but the box office and CinemaScore support it, and the way Disney had cancelled or postponed a ton of projects suggests it's widespread.)

There isn't an issue with the purchase being somehow bad. The issue is they're intentionally destroying the means to authenticate they were the ones who purchased it.

I'm totally on board with purchases being tied to a single company being an issue, but for a lot of people the value of digital books and music is the online availability. You're going to need some sort of auth for that to work.
> They are using the same principles of acquiring randomized samples, so it's still compressed sensing,

See the second part of my comment. This is only in principle. In practice compressed sensing uses a higher frequency basis and more importantly, this basis is generally not learned, preventing common case bias. Ie a rare condition won't be ignored because it isn't statistically common enough for the NN model to learn.
