If an object started off as a 10-km rock, and was pulverised to a dust cloud, that dust cloud will disperse across thousands of kilometres, some of it likely missing earth entirely.

Area of impact for original rock: 78.5 km2
Area of impact for a 1000-km dust cloud: 785,398 km2

Asteroids that struck 65 million years ago had 3×10 ^23 joules
In case of dusk cloud, that's 382,000 Megajoules per square meter impacted

A column of air with a cross-sectional area of 1 square centimetre (cm2 has a mass of about 1.03 kilogram
A square meter of air column weighs ~10 tons
Heat capacity of air is 1.0035 joules per gram per degree centigrade
So it's 10 MJ to heat up 1 m^2 of atmosphere by 1 degree

So if all the energy was absorbed, converted to heat, and evenly distributed vertically (unrealistically), it the atmosphere would heat to 38,000 degrees. If this is in the right ballpark, then radiation will dominate this equation, which I can't estimate. Upper atmosphere will be heated to a glow, and will radiate away most of this energy. Whatever happens, not a happy scenario.

For a dust cloud 5,000 km in diameter, situation is quite different: 3,821 megajoules per square meter, that's 382 degrees rise per square meter. For comparison, the Sun provides 115 Mj/m2 per day.

I would anticipate that in case of 5000 KM dust cloud there wouldn't be a major loss of life - the atmosphere doesn't conduct heat very well, so most of it would be stuck in upper atmosphere and radiated away. I think a realistic 'space dust cloud' would disperse very quickly to greater than earth radius, but it's not going to be uniform dust.
Innovation is inventing something new; imitating others and catching up with the rest of the world a decade late is not it.
It's quite easy but it depends how you want to do it. Would you want to take an existing PWA codebase and deploy it in the best possible way to mobile, or do you want to wrap the existing externally hosted PWA? Both are possible but the former will be more likely to be accepted into the app stores.

Capacitor can be added to an existing web app codebase and acts as a library with cross-platform APIs for functionality like Camera/etc and that would be compiled/linked into your app like any JS library. But it can also be used to wrap an externally hosted app by changing the server.url config value https://capacitorjs.com/docs/config
Pure dread, when you have signed up for a new gig and open an existing code base for the first time. Starring at hundreds of unknown files and folder with no idea what anything is and how it all works. No going back, you're a new maintainer, so better get to it. Usually after a few days you start getting a grasp, and it's not so bad though :)
What are you, some sort of nigger?
I was confused by all the products also, until a family that owned a landscaping company moved in next door to me.

Their yard was basically a dirt lot with no grass. A month or so later and it was a lush green landscape.

It seemed like all they did was cover the yard completely with manure. After seeing their success I did the same and my yard turned green too.

Was it the manure? Yes, but also no. I moved across country and manure doesn't work like it used to. It was really the expert knowledge that did it.
I remember those arguments and races - and it all fell aside when people just hearthstones you Dalaran which was faster than both.
I was in a similar situation a few months ago.
I had previous positive experience with k8s and some negative experience with nomad, so I was torn between k3s/k0s and just docker stack+swarm.
I didn't want to install anything as I started with a minuscole node (5$ digital ocean node).

In the end I went with docker stack + machine + swarm + docker flow proxy and it's been pretty smooth sailing.

I don't need anything else installed on the machine, I can develop stacks locally with docker compose, deploy them to swarm and I can even add replication on multiple machines for services that need it.
I manage secrets with stackoverflow's blackbox and the secrets live in the repository encrypted.
I can easily run commands on the local or remote stack via docker machine.
I cheated with cron jobs and I just synchronise /etc/cron on all hosts with a directory in my repo. The commands are mostly running commands inside containers.

I have one stack for redis, postgres, docker registry and multiple stacks for other applications.
The flow to deploying stuff is basically: generate id from git hash, build docker image, push to self hosted registry, stack deploy with the git hash as version.

A few caveats I found:

- Dependencies with docker health checks will take the duration of the health checks to become available to services needing them. Either you skip health checks or setup things so that infra is running before your services.

- In order to use docker-machine on multiple machines / with different contributors you need to export the key used to setup the machine and export it (there is a npm package that works very well, but it would be nice to have it natively).

- You have to cleanup the docker registry manually every once and then (I had to write a cron job for that)

- I'm unsure about the future of docker, albeit things work pretty well as they are.
Here's the medium post the BBC team put together last year. We're huge fans of what they've built! https://medium.com/bbc-design-engineering/shipping-progressi...
Recently I looked into this subject and talked with a postdoc researcher. It is interesting to see this discussion on HN.

C elegans is far more complicated than the connectome abstraction used in these projects. There are all kinds of ion channels, including new ones recently discovered (https://pubmed.ncbi.nlm.nih.gov/34388373/ ), that are regulated by genes and other physical/biochemical factors in the body that are very poorly understood. We only have slightly better understanding of its brain development recently ( https://www.nature.com/articles/s41586-021-03778-8 ). The in vivo research on C. elegans neural system mostly uses the concentration of Ca+ as the neuron activity indicator, which lefts out other details.

According to the postdoc that I talked with, we are still very very far from even accurately understanding a single neuron, let alone simulating any neural network completely.

You can not easily create more land, as a country.
Every 2-syllable word means something in some language. I don't see why people get so hung up on it.

If Facebook needs different branding in Israel, they'll do it. But they probably don't need to worry about it because Israelis speak excellent English and have a great sense of humor.
How many planes land & take off every day though? Over the course of a decade, sitting in small quantities on literally ever outdoor surface...

Comparing it to lead paint is the wrong comparison. Take a look at what lead in the water supply, even at small concentration, can do to people. That's more comparable to air dispersal.

As a city slicker who understands nothing of modern agriculture, can I get an explanation of what is going on here?
Interesting point! And in fact, since you can pass along most assets to your heirs without taxation, even your death won’t prompt a sale.
A Georgist[1] land value tax, perhaps paired with a citizen's dividend (i.e. UBI), has long been the economically optimal solution to this problem. I've yet to see any proposal with better math behind it.

Again, no. Try writing Netflix and ask if they can add something to their "library", they won't. Libraries adds stuff based on user requests all the time, and even have 3rd party loans so you can borrow books from another library via the one you have access to.

All Netflix cares about is profits. All libraries care about is sharing. They are two very different entities except for the fact that they deal with media. They are more different than they are similar.
Also, the boom of affordable, basic amenity new construction post-war was subsidized for (white) veterans by the federal government[1].

I'd be curious to know more about the average cost of this setup over a few months, and how scaling up/down affects the cost.
Regarding your last sentence, I think technical jobs, and especially people who write code as part of their job, are forced to develop a special kind of humility. Engineers, scientists, technicians, deal with the law of physics everyday. As a developer particularly you get immediate feedback dozens if not hundred of times a day. You can't bullshit your way out of a bug. The computer is cold, rational and executes the piece of code you wrote. You can't convince it to run your program with pretty words.

This is in contrast to other jobs, for example marketing specialist. As a marketing specialist you spend weeks or months on a well crafted marketing campaign, then you launch and the results are not bad but yet not great either. There could be millions of reasons for your campaign to have failed. You could job-hop thinking you did a great job and blame the lukewarm success on external factors.

There are people who spends their whole career failing at what they do who would never know otherwise because their job lacks this sort of cold instant feedback.
As I was reading this all I could think was that this should be popped up before any stackoverflow post is allowed to be submitted.
All modems were compatible with Linux until very late in the piece, when so-called WinModems appeared commercially IIRC ~1998.[0] In these, processing done in hardware on other modems was offloaded to the CPU via closed source systems. This was probably only possible as CPUs had become faster, and was likely done to save cash and PCB space in Y2K-era laptops. I think they were eventually largely supported under Linux, but basically by this time nobody needed them anymore. The reason modems were all so well supported was that a stable serial interface was largely supported across the board by all vendors. After serial line configuration, only vendor-specific extensions and a slow evolution of additional features such as caller ID differed.

It's interesting that you didn't correct me on Liberia, which actually merely had its currency pegged to the US dollar temporarily. I must have mixed up Liberia with another country.

El Salvador is a fun case because they didn't exactly switch to the US dollar because their economy was doing so great but because it was either that or massively devaluing their already dodgy currency because they are a very small country and their economy heavily relies on international trade.

They introduced Bitcoin as "legal tender" on top of the US dollar against the will of the majority of their citizens but the law was part of a program to lure in foreign investments. This too followed earlier economic problems, so it's more of a cashgrab than a genuine interest in crypto currencies.

El Salvador replaced its currency with the US dollar. It did not replace its currency with Bitcoin. It also didn't replace the US dollar with Bitcoin, it just added it as a form of legal tender. It also suffered almost immediate consequences when the price of Bitcoin crashed and they had to dump additional money into it to compensate for this.

It's too early to say but at the moment this doesn't sound like a wise political move for El Salvador rather than a risky publicity stunt for the president.

When I first read Snow Crash, I thought (perhaps wrongly) that there was also an advertising model to supplement the real estate business - and one that went hand-in-hand with it.

I love the passage that introduces "the Street", and it's the last sentence of it that gave me the impression of an advertising business model.

In the real world - planet Earth, Reality - there are somewhere between six and ten billion people. At any given time, most of them are making mud bricks or field-stripping their AK-47s. Perhaps a billion of them have enough money to own a computer; these people have more money than all the others put together. Of these billion potential computer owners, maybe a quarter of them actually bother to own computers, and a quarter of these have machines that are powerful enough to handle the Street protocol. That makes for about sixty million people who can be on the Street at any given time. Add in another sixty million or so who can't really afford it but go there anyway, by using public machines, or machines owned by their school or their employer, and at any given time the Street is occupied by twice the population of New York City.

That's why the damn place is so overdeveloped. Put in a sign or a building on the Street and the hundred million richest, hippest, best-connected people on earth will see it every day of their lives.
And we are adding 1% to our population each year, making housing that much more scarce even if nothing else changes.
At least notifications, if nothing else.

Hello,

I would like you guys to post ideas for technologies which still require more processing power than is currently available.
The causation will be more like if you have two neighboring school districts, the one with higher house prices will tend to be the good school district because the kids’ will be coming from

Video: Wolfram on "What is space (and time)". Does compute underly everything? @37:10 https://youtu.be/qoDZKlcdPNM
No.

It should be taken into account, but it shouldn't be considered "definitive" evidence (compared to something like a video footage).
You are right, netflix is better. Netflix has to earns its money, netflix has a serve its customers, Netflix has to provide value to each individual subscriber.

The government does not have do any of these things, they just seize money via threats of violence. There is no comparison.
There are two things in life that bring me joy like no other, and they're basically the same: completing a physical fabrication project and successfully implementing something in code.

The elation I get when it comes out exactly the way I imagined is unrivaled.
Yeah everyone loved it when Bezos did that...
Yeah I don't know if it's the same everywhere, but the concept of how medical residency is handled in the US is just insane.
There are two big problems with your statement:

1. You ignore the big problem that buying a house shouldn't be the only way of finding somewhere to live. Like, that's just not realistic. You're 18 and you want to move out of your parents' house. Is your only option really to buy a house while working at Dairy Queen?

2. The idea that a market can be cornered like this is overly simplistic and history is littered with the bodies of those that have tried. Like anything, the pendulum swings back and forth on this. You only have to go back to 2008 to a time when the market was flooded with available units. What you have now is people who 100% have legitimate concerns that I support but tend to overstate the doom and gloom as being forever. Obviously that doesn't help them now but the idea that someone can forever lock people out of the housing market just doesn't hold water. Structural changes in the market will come along and change the equilibrium.

IMHO one of the most damaging things to the housing market has actually been AirBnB.
Is there any github list with this ?

I had a security dog in an airport come and sit next to me while I was standing in line. Thought for sure my day was over, really freaked me out because of stories like this. Nothing happened, I think the dog just figured me for the dog person that I am. You are not supposed to pet working dogs while they are working but that didn't stop me.
Apartments and condos in the United States are built as cheaply as possible. Developers love the 4 over 1 style which is the most they can get away with. Combined with hideous "developer modernity" styling.

Neighbor noise is the top issue with this style of housing, but it goes completely unaddressed during building. I've always wondered why nobody has tried to differentiate on that.

I would be happy to live in a condo instead of a house if I felt really comfortable that I wouldn't have to deal with noise. But as it is now even if your neighbors are quiet at first, they could sell to someone with a new baby and you're screwed.
You bring up an interesting point. But even at the peak of slavery in the US, there were "white" people who believed all people are created equal and deserve equal rights, some even helped free slaves.

I think it is more of a worldview thing which is influenced by local culture. You beliefs about answers to fundamental questions like why do people exist? What are valid authority systems and structures? What is the origin of humans? And more questions like this, makes the difference.

I believe racism is wrong because I don't believe race is a thing beyond a social classification system. I believe in ethnicities and diffrences between them, but humans share a common origin. Even if some humans have less or more capability to do certain things than others, in order to be just, one must evaluate others as individuals not groups. Even if some statistic about a group can predict behavior of all but one members of a group, prejudice against that one member is still unjust and unfair, We should treat others the way we want to be treated ourselves.

But back to the topic, I think I agree with you that why we believe privacy is important is critical to make any improvements or changes. Simply put, privacy is power. When someone deprives you of privacy against your consent (where expectation of it is readonable), they are excercising power over you. They are excecising a claim that for whatever reason, information about you now belongs to them. If all or most information about you belongs to someone, you are now their subject.

It could be as simple as a lack of understanding of the implications of privacy deprivation.
LA is, however, building more condos than most other areas. They tear down an old 1950s or early single family and put in four ~$1m units... that's better than the Bay area that refuses to do that. This is of course neighborhood by neighborhood so it may not be at the necessary scale to provide relief.

I love LA though but the housing situation really does suck.
I think they might have meant "crap to develop for"?
I got Disneyland vibes from central Prague, probably for that reason that nobody really lives there. A lot of people say it’s their favourite place in Central Europe, but the short visit I had to the central areas just didn’t click for me. I’d be interested in seeing more of the normal areas where people actually live
Unfortunately the article is extremely sloppy with the numbers and that makes it very hard to understand what is really going on.

Primarily, they keep mentioning "average house-price-to-income ratio" but appear to be using average home price and median income. Both housing price and income distributions are enormously skewed. In the Unites States average income is almost double median income and that difference has been increasing over time. So right there, even if median house price to median income has stayed constant, you would notice the pattern pointed out.

I don't doubt the central premise that housing prices are rising faster than income within household, but unfortunately the article does nothing to show it.
Dropbox Acquires Command E
I think that’s the point everyone replying seems to miss. Finding the right question to frame the problem can be as hard as the problem itself.
People that think housing prices can never be solved remind me of the infamous we ‘can’t drill our way to lower gas prices’ quote.

Well.. it didn’t age well, fracking was invented in the context of a policy framework that only exists in the US, and now America has 7x lower gas prices than the EU/APEC and can’t export fast enough due to liquification capacity.

This is to say that there is likely a technology/policy innovation pathway to disrupt this current situation, but people aren’t thinking on a large enough scale yet… and investors, unfortunately, aren’t aligned to fix this because they own existing assets.

This means, the policy framework required to fix this tragedy of the commons looks something like making it profitable for investors to make money by 10x’ing the housing supply, 10xing the manufacturing speed, etc.
It does not beg the question. It raises the question.

Any form of argument where the conclusion is assumed in one of the premises. Many people use the phrase "begging the question" incorrectly when they use it to mean, "prompts one to ask the question". That is NOT the correct usage. Begging the question is a form of circular reasoning.

Logical Form:

Claim X assumes X is true.

Therefore, claim X is true.
Going down the list:

- Apple: next...

- Samsung: supports unlocking the bootloader (enable developer options, enable OEM unlock, boot into download mode and follow the on-screen instructions for "Unlock Bootloader")

- LG: supports unlocking the bootloader (see http://developer.lge.com/resource/mobile/RetrieveBootloader....)

- Lenovo: supports unlocking the bootloader (see https://www.zui.com/iunlock)

- Motorola: supports unlocking the bootloader (see http://motorola-global-portal.custhelp.com/app/standalone/bo...)

In other words, all devices in your list support unlocking the bootloader.

I've used devices from many different manufacturers from around 2010 onwards, none of them run vendor distributions. It used to be difficult to install new distributions but this has not been the case for more recent devices. I'm in Europe but often source devices from elsewhere since they are not 'officially' sold here.

Can you address the point without reference to Trump? We were talking about Clinton, not Trump. If it helps, I think they both were self-serving, full stop. But. Whenever a criticism of Clinton hits the mark, a supporter invariably pops up talking about Trump. It comes off as an attempted diversion from Clinton herself.

So, to the point, she was not even implying that those who were on the fence about her were motivated by racism, sexism, Russian manipulation, etc? She acknowledged there could be principled reasons to disagree and not vote for her?

This +1. Housing I the US is broken in a fundamental way, it needs to be seen as a bad investment to get better. If we targeted say 2% annual price decreases in housing, the world would be better off.
