Your thoughts echo mine very closely. Uncontained spread seems fairly well unavoidable at this point.

By all accounts, the Chinese have so far done a good job of containing the spread inside their borders (outside of Wuhan). But I feel there's a significant lesson to be learned from how the virus exited Wuhan in the first place: containment measures applied too late, after the scale of the problem became too obvious to ignore. I fully expect this response to be the norm, across all scales from community to city to nation.

I think that China and other large (in terms of area) countries like the US will come out of this "OK", modulo the economic impact. For the most part, intranational travel is funneled through long-distance rail and air routes, which are relatively easy to monitor and control. I have more concern for e.g., Western Europe, where there is not a significant geographic separation between the major population centers, and where there is a strong expectation of free & untracked movement.

Multiple doctors in their late 20s or early 30s have died from the coronavirus. If you are under 18 and have good health, then you are pretty safe.
Heh, well I just wanted an idea on scale. It doesn't take millions of years, but less than 100.

Certainly it wouldn't likely be 100% every 30 years, but 3.3% every year. As far as geo-engineering significant climate change this looks like one of the easier approaches actually.

Of course it's much more feasible with the continued migration towards solar, wind, hydro, and related.

Sadly I think Nuclear got the short end of the stick for mostly political reasons. Things like putting a nuke plant in a known tsunami zone, without protection, because of political lobbying.

So all in all, agreed.
The docs list WASI as currently experimental[1] and has missing features[2]. I understand how the sandboxing approach can add security, but if using experimental technology to enable this, doesn't it potentially open up more new holes than it closes? I'd love to hear more detail about what exact parts of WASI are used here, and what happens if you compile C code that targets a "rough edge" or "missing feature" of WASI by accident?

If people around you are going without food for 7 days or longer, you still have a problem, and it’s directly proportionate to the number of very hungry people that live around you.

“Safe is anywhere a hungry person can't walk in three days.”

can you use code directly from shadertoy for a new preset?
This, unfortunately
And sometimes you just fall on your own as well. Out of the few times I’ve met the ground while biking, I’d estimate roughly half to be because I lost balance after hitting a pothole I didn’t see or ice/snow/rain making my bicycle slide. I was glad to have a helmet in these cases.
How do you calculate how much energy is required?

You would use cooled separated products to pre-cool incoming stream of "dirty" air. CO2, having low concentration, won't fall off at -79C (or we'd have that effect in Antarctica today), but if you go to ~-140C, you'll have some results.

Why cooling process will produce greenhouse gas? You'd use energy from "green" sources to compensate for required expenses.
? The people providing healthcare today, are as you described, except they have huge, fat, ridiculous margins. They commit what would be point blank fraud in any other country, all day, every day.

Walmart is a massive machine that operates by design on thin margins. They force out surpluses all the way down the value chain and in their own operations and instead of selling at max margin, they sell at low margin, because they know they win in the long run.

Walmart might be exactly what you'd invent if you wanted to provide healthcare at the best price to the most people. There's the possibility they could be more efficient than any system anywhere as most public systems are full of fat as well ... certainly more than the 5% or so margin Walmart might take in.
Yes. I wanted to keep things simpler for people who don't speak Haskell; and show off composition of simpler combinators to build more exciting things at the same time.

In eg OCaml you have to use something like zipIndex (but implemented differently) or mapWithIndex, because they don't do lazy data structures by default. (And in eg Python their lazy sequences come with lots of caveats because they are not referentially transparent.)
Why not just postpone it for the same time next year? It's still possible and not a complete cancellation either.

I'm not sure what this is? You might be thinking of solar radiation management or other "geoengineering" techniques to try to make the earth shiner and reflect more sunlight, making us cooler at a constant CO2 concentration. Theres a ton of interesting topics within that to write about, I mention it briefly as "things I didn't include"
Totally agree. Plus this feature is just an “extension” in Firefox, and you don’t need to sacrifice “the future of the web” for yet another gimmick.

PS the only place I hear about Brave now that their clickbait articles on tech sites all but disappeared is here. Yes. The verY sites their revenue we are suppose to want to protect so they can sell us infomercials pretending to be content.

It’s obvious we can’t leave the web in the hands of corporations, neither Microsoft, or google and definitely not brave? which is ran by a morally questionable and compromised Brenden Eich to begin with.

Perhaps you could enlighten me instead of being arrogant?

The state of prisons is avoidable and due to society not caring enough. Is that a false and ignorant claim? Why? I think you should explain because I think that may claim is patently observable and a matter of fact.
Why do contemporary designers fall for the following trends over and over:

- Magenta/Purple colors

This seems the trend these days.
Agreed.
If you’re interested, there’s a book called The Kasinomic Revolution by GG Alcock that dives into the potential (and importance) of the informal sector of South Africa’s economy. It doesn’t go into the employee exploitation that the article covers but has some truly amazing insights.
This! When I was in China the experience was as described by your parent comment except the doctor insisted she give me a prescription for herbal medicine since it's better for me... (Had the flu, REALLY wanted nyquil, but it's illegal there it seems).
Yes, but that argument would prove too much. People get very anxious just from browsing medical information on the Internet and matching up their easily observable symptoms.
Everyone here saying “hunger goes away after 3 days” should read more about what desperate people do during prolonged famines.

If it comes to that, your “neighbors” aren’t going to be sitting around doing yoga to feel less hungry.
Viruses don't live for long periods of time outside their hosts, so rations could still be delivered if quarantined.

Instant Pot is great for cooking food and it not spoiling too fast (e.g. meal prepping), but overkill when we're worried about viruses.

I did a quick inventory today and estimated we have enough calories from sugar, rice, beans/pulses and oil alone to live for 2+ months at normal function without weight loss. And enough other things for nutrients and many more calories. And that wasn't even planning for anything. Maybe I buy more than we need...
Thanks. You've calculated the energy required to pressurize the gas. You can get that energy back if you make the gas doing work; if you pressurize it quasi-statically, you at least won't lose energy while compressing...

I didn't get your last line though. I assume you compress "dirty" air.
> not including people who returned on evacuation flights.

This bit seems important. The “only 400 tested!” statistic people are citing seems much more reasonable in this context.
But they only need to be right once.

Software development never gets that abstract. Yes there are abstractions, but compared to college math, they're extremely simple. The most complex abstractions I've come across in software engineering don't hold a candle to some of the abstractions you would see in a typical undergraduate math degree. Heck, my university used Baby Rudin [0] for its introductory analysis class, which was often taken by freshmen or sophomores.

"Doesn't apply to healthcare."

Yes, it absolutely does. The vast majority of 'healthcare' is operationally mundane, and not hyper-specialized such as those who are in car accidents might require.

Most public systems are quite inefficient, and without any possible market pressures (Canada healthcare act makes it technically illegal to sell healthcare services that are provided by the gov.) then those inefficiencies sink in.

Because there's a weird inelastic demand for certain services, pure market-oriented solutions won't work for 'car crashes' but they definitely could for most other things.

Walmart taking on healthcare is a very meaningful event, they could feasibly operationalize the more mundane issues to the point wherein it's the cheapest in the world for such services. This is hugely positive news.
I see what you did there:

"for content marketing [...] now we do longer, more comprehensive guides, and we cross-launch those to Product Hunt and Hacker News"
I agree. Back in the day when I used Ruby, I remember one of the arguments for Python being their belief that there should be one way to do things. Found one reference:

> There should be one-- and preferably only one --obvious way to do it.

Thanks for the recommendation. One thing for sure is that exercise if a massive factor considering the time we spend sitting still in front of screens. Our bodies aren't meant for that.
> relatively low-traffic countries like Nepal and Sri Lanka seeing cases very early on

Sri Lanka is/was already in season and a significant amount of their tourists are Chinese. Or would be, as Visas are now cancelled so there aren't any anymore.

Wouldn't call that low traffic or put it into a two items list.

Can anyone just explain how in hell it takes so long to develop a vaccine?

Vaccine creators aren't supposed to have billions of USD to make their job? What's the real problem here?
My biggest concern about CO2 is the cognitive impact it has on humans - at levels 800ppm and higher, mental performance is impacted. It will take a while for the atmosphere to reach this level (hopefully it never does), but it is common inside houses and offices. As atmospheric CO2 rises, it becomes more difficult to ventilate buildings, and human mental performance degrades.

In terms of geoengineering, it seems like these two are our best bets:

https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio... to prevent runaway warming. As a side effect, the dispersed sunlight helps plant growth. Solar power generation is negatively impacted though.

https://en.wikipedia.org/wiki/Iron_fertilization to sequester CO2. As a side effect, marine life and fish stocks would be boosted by the greater plankton food supply.

In any case it seems absolutely bonkers that we are still selling fossil-fueled-vehicles and building coal power plants when we clearly have the technology and capability to replace both of them.
It's based on an engine called Milkdrop that is a very popular music visualizer in WinAmp...
So it has nothing to do with ShaderToy.

Have you got a reference for the 800ppm bit? Not being provocative - it'd be genuinely useful to me.

Yes, it does.

GREAT work.

Two (small) comments:
- Perhaps the review of the re-forestation option could mention that this has a number of positive side effects (outside of carbon capture), for example on rainfall and wildlife.

- as there is a time constraint on co2 capture (e.g. 2050), and as the various co2 capture solutions are not all at the same stage of maturity, it could be useful to have a table/chart that summarizes which co2 capture options are deployable now vs. at some stage in the future
Let’s be very clear here since you like making insinuations for my comments.

I wasn't making insinuations. I generally do my damnedest to try to phrase things as neutrally as possible and make sure, to the best of my ability, that I'm not making insinuations.

You aren't required to engage me. If you don't like engaging me, then don't. You don't have to.

You can just let your original comment stand on its own. Nothing I say erases anything you say.

Readers here are generally intelligent people who can draw their own conclusions and can see that "These two people seriously don't agree."

There's zero need to formally state that while continuing to engage.

That's not an insinuation. It's a description of online social dynamics that isn't readily and immediately apparent to a lot of people because it runs counter to how in-person conversation works. (That includes me. It took me eons to figure that out.)

This will be my last comment in reply to you. If you feel the need to reply further, that's up to you. I'm absolutely not looking to have some pointless fight.
The problem with the US is that healthcare is so broken that nobody will want to go to the doctor to get checked because it's too expensive.
HeliumHQ used to be the commercial offering of Helium. We shut down that company at the end of 2019. The GitHub link you see here now is the same code, modernized and open sourced. See the history section at the bottom of the GitHub README.
No, the idea is something similar to this - https://sesinnovation.com/ .

You carefully compress incoming air. Separate water vapors (and liquids, and hopefully not solids) from it. Cool this air in thermal exchanger - at this point CO2 falls off. Then you pass that air through turbo detander, which returns you some energy, and get a pre-liquified air, which pass to the thermal exchanger. Clean air of normal temperature is released to atmosphere.

You have to compress the air - but you also cool air, so compression is easier, and you also get some energy from the turbine where you decrease the pressure. Subject to optimizations. How much energy will you need?

It's not a power the EU has. Health care as well is just not a subject the EU has any role in.
You don't want to do unnecessary transformations, to preserve as much energy as possible (so the turbine, which is needed for cooling, should work on small pressure difference). So, no air liquification - just let CO2 separate and send cleaned air back to the heat exchanger.
I don't really agree. I've had my car broken into twice, none since I pointed two cameras with bright red rings of LEDs at my car.

I find it quite useful to know when a package is left at my door.

My control system for lights can make the house look lived in, but is also really handy for controlling lights where they are hard to reach.

We have no useful front facing windows, it's quite nice to know when friends/family drive up for a kid pick up, visit, whatever without having to wait for them to knock.

It's nice to know when things happen, like a tree falling and landing on your house. Also handy if you have a surprise and your kid/wife/house sitter/plumber needs inside your house and your not there.

I just wanted to point out that home automation and surveillance have quite a bit of overlap and can be useful for more than detecting unwanted intruders.
It's only a matter of time before this becomes a massive problem for the city. I applaud UCSF for not letting the two patients from Santa Clara start a local outbreak.
Japaneses prefer to kill all the population defending their "honour" than being rational.
As someone tangentially attached to the sports community, the olympics is already a bit screwed up anyway, simply because the sports seasons (and thus the qualification pathway) for many events in the games have been significantly disrupted by the coronavirus. Many athletes who were in touching distance of qualifying will not be able to, and other athletes will be sent in their stead (if it happens at all) Olympic qualification in most sports is extremely complicated, and this is having a serious effect.

That being said, sport is not so important (imho) that public safety should be put at risk, and cancelling the games (or postponing them) would seem a sensible option if things continue to get worse.
We all have family, etc. over 70 though.
Not the EU as an institution but single countries. I wouldn't be surprised if Austria closes their border if there are more cases in Northern Italy. Germany, Switzerland and France could also follow. I believe they'd still let freight through (maybe with tests for drivers) to not hurt the economy too much. Ironically, the refugee situation a few years back helped those countries as they now have the infrastructure to patrol borders better and built centers that could as well be used to isolate potentially infected people.

But I also wouldn't count on all of this happening too fast, there's still passenger flights arriving from mainland China in Europe.
That is just power fantasy. Do you have any evidence that shooting people for breaking quarantine has effect? I think it just causes people to avoid doctors if they experience symptoms. People do not want to "disappear" into quarantine. I lived under authoritative government and know how it works.

Initial situation was made much worse because China policed their doctors.

Also I do not think that China actually shoots people. It shutdown transport and pumps money into economy. Other states could do that as well.

I understand that. But I'm not talking about Coronavirus in particular but the threat of a pandemic in the age of antibiotics.

This one might be a virus but past pandemics like the Black Plague were bacterial in nature.
I like the way this is framed in terms of the comparison to a religious experience. A few years ago I had one of those "unified model revelation" experiences in a non-mathematical field, and based on that experience I think I would ask the author how the follow-on learning or application went. In my experience, the intuitive "experience of the knowledge" was much more striking than the eventual unfolding and application of the logic in that case. However in other cases, the intuitive experience of the revelation/knowledge was weak, yet the model turned out to be somewhat randomly selected by others as interesting or applicable.

I thought this was interesting--that the revelatory experience can end up being so subjective and limited in the goes-nowhere-from-here sense, yet it feels so darn amazing at the time. I wondered if it was similar to seeing a Tetris happen for the first time. An emotional reward in the sense of rewarding an organizational triumph of the mind. And seeing it with the intuition is one of those things our mind loves to count as actually seeing it in real life.

(I've also experienced this as a practicing religious person; in religion though, the subjectivity can quickly become a bummer because the question of one's worthiness or lack of discipline is nearly always up for discussion, especially when you ask why the results were disappointing or something like that)
The problem is even that you can't properly prevent catching it if people are isolated at home since masks and disinfectants start being sold out pretty much world wide.
I'm so fucking tired of this perspective. Yes, it's technically correct. Many of us have done the canonical "cancer screening false positive / false negative" example demonstrating the problem in a statistics class.

But at the end of the day, I'm paying a doctor to care for me, not the general public. I may be a member of the general public, but the public interest and my interests are not identical.

If I'm willing and able, I should be able to pay to have a test done (anonymously), and be left alone to deal with the statistics of what the results actually mean for myself.

The fact that I have to fight my doctor to do this is condescending bullshit.
Now you can take NSA's free course for beginners
It's nice to know.

Was it a neighbor, who just hasn't told you yet?

Was it a malicious theft... by someone you know?

How often do such thieves go by? Which car do they use?

What's the risk? Should you pay for a pakmail/pmb/po box?

Raising the bar to package theft, vandalism, stealing cars and similar can help reduce the chances of it happening in the future.
> modulo the economic impact

This is a BIG modulo, China alone was already a disaster but now that we can see the rest of the world will be hit, the economic consequences will be disastrous.

2008 was a walk in the park compared to what may happen.
