The data comes from 4 prisons. It is theoretically possible that all 4 of them happened to be in the same window after an initial infection, but it doesn't seem very likely.
I guess the only way to be sure is to do follow up tests every week or so, hopefully that will happen.

Ask HN: Who are you. Please give hubris, examples from me below;
1. Im the guy who, when working in DRG (developer relations group) proved out Celeron processors, SIMD, APG, and the multi core could be a thing (i was taking a piss next to andy grove in 1997 in SC5 and i said why cant we just stack cores on top of another.(later in 2004 on a hike with a researcher to learn we had 64 cores, stacked.

I teied to work with the primary MIPS dev to do (some things) and it later became what we think of as a cabinet.

I was the prime designer of the the presidio lucas film project.

Sf “zuckerberg” stupid fucking hospital - zuck actually paid to pit his name on the fucking hospital i designed then wh i workekef on helping with his open concept menlo campus, rio office and the sydney office they fired me for and i am being very specic and accurate and direct “being too social” — to fucking social for facebook?!

I have a tone of war stories, what ate yours?
I agree with this. I think people don't mind text being there, as even all so called Visual Languages have text in their boxes. People want to understand "what" their program does in a more clear way, and Structured editing, lines or arrows, highlighting just the relevant information, and more simplicity do just that.
You can use Nix on your Linux (Ubuntu, maybe Gentoo) for the projects you want without going full NixOS.
> The alternative is to travel by car. But people can only tolerate a certain amount of time in the car

We routinely drive 2000 miles round trip to visit family. People can tolerate lots of time in the car if they really want to go somewhere.
It's nice to have another source on this. I saw a similar comparison from an Italian site:

New York has been criticized for retroactively adding older cases. The Johns Hopkins data just tacks it on to the end of their time series, creating a weird spike and screwing up what the data represents:

I wish they would simply remove every second seat and charge twice the price. That would mean the same revenue for the airline and a much more comfortable flight for me. Win win.

And they would probably still have some wiggle room. Because 50% less customers would mean at least some reduction in costs.

What about the HN gang? Would you keep flying if prices doubled?

I recently had some fun writing arm64 assembly. My experience is that hand written assembly is faster if you apply the same cheats that the compiler uses. 3 things to keep in mind: 1) Make use of the registers; 2) Avoid branches; 3) Get familiar with the instruction set and make good use of them.

My family (child, spouse) and I live car free in Oslo, Norway. It’s amazing.

We used to own two vehicles when we lived in the States. I did take public transportation during the week, but still had to drive almost everywhere else. When everything is designed around cars, it can be extremely difficult to try and go without.

Oslo was mostly built before cars, so roads are smaller and highways go below or around the city. Oslo is slowly making it harder for cars to be within the city, and actually changing streets to be car-free. Having a car here is not a need, but a want. I like that.

There is precedent - losing a war. Economies do recover. Germany recovered from being bombed/burned/bankrupted flat in WW2 to become the economic powerhouse of Europe.

Other countries did not recover so well, mainly because they chose more socialist economic polices.

No, it wasn't because of the Marshall Plan. Most of the MP money went to other countries, not Germany.

I am on you with this, sure English de facto language for many things. I don't believe it's just for business or research many things but most of rural areas or less educated areas all over the world has little amount of English speakers or even not at all.

For instance, let's take Spain or Italy not even Africa or Asia. I mean Europe, Spain, if you asked 20 people in Barcelona or Rome you'd end up being understood. On the other hand if you asked 20 people in Naples or Granada, the chances are they wouldn't understood you.
>For example, there seem to be multiple events where people get sick even after it has been established that they have antibodies.

Do you have a source for that?

Will that help with the virus? It is less than six feet and you will be with that person for hours or so.
If I wanted to pay ~double for a more comfortable flight, I'd be flying first class everywhere.
I've used NixOS, it's a great project and has some benefits that can't be overstated, however if you're going to give it a try completely you kind of have to go down the rabbit hole. You will basically be learning a programming language that will let you configure your system. It took quite a bit of getting used to to understand how the language nix works, as it wasn't familiar to something I had used before. One might not have as much difficulty getting used to it as I did if they are experienced with functional programming, which I've only dipped my hands into before.

I'd recommend giving it a try if you have some time on your hands to get used to it, but you shouldn't be expecting a quick switch.
The election isn't simply between those two parties, and with just a handful of seats going differently Labour could have had its first Prime Minister since 2010. That's a win.

I agree! Showing a bit of the markdown in the rendered text really gives the page a nice hacky feel. I'm doing something similar on my website[1] but this blog looks a lot nicer then mine!

The biggest problem on my version I think is that links aren't obvious enough in dark mode, but I like the links used here so I'll look into that.

After a certain point, the more well-off could own a VCR and record off TV; that is, time shifting, which is something Universal made a Federal case out of.

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

Incidentally, the practice of time shifting is a reason VHS caught on and other home video formats didn't:

LaserDisc didn't offer time shifting at all, so it wasn't even in the running here; as a result, its pitch wasn't as compelling.

Betamax did, but its tapes only held one hour to begin with, which isn't enough for a sports game or a TV movie. It was only arguably of higher quality on the TVs of the era, and the fact its time shifting capability was half of what VHS could offer in the same time period made it a less attractive option.

(Both Betamax and VHS increased recording times as the format war wore on. However, after a certain point, merely being the entrenched winner has an impact on how the competition goes.)
Basically, digital technology. We now have access to so much raw data, with such immediacy, and the capability to process it, that we can identify and work around problems and find more efficient solutions faster and better than ever. The main way this shows up in society is probably the maximization of profits that leads to increased wealth/prosperity. That doesn't describe who is getting that wealth of course :), but it's there. So we have a better opportunity and capability to solve problems than ever before. The trick is getting society to adopt it properly.

WRT the logistics of scaling a supply chain, we have the capability to identify supply chain inefficiencies and provide fixes. As a store sells out of toilet paper, it's possible for the store's database to be linked up to the toiler paper distribution company, so they know when a shortage is happening in real time. But how long does it take the manufacturer they buy from to spin up more TP? Too long. To fill the gap immediately, the store would need to detect that the original distributor won't be able to fulfill the projected increased capacity, and start filling orders with some other distributor somewhere else in the world to get more TP. But we also may be assuming that the whole world isn't having a shortage... if it is, is there enough cargo plane capacity to ship from these remote places? If not, more logistics is needed.

The capability to automatically perform that logistical ninjutsu at each stage of the supply chain is now easier than ever. But nobody ever programmed their systems (much less signed the right business agreements) to actually do it, because nobody really needed TP to "scale". And this is the actually hard logistics problem: it's not enough to have the capability to do something, you have to actually implement it in your system. They haven't done that, so the supply chain doesn't automatically scale.

But all of that ignores the impact of a global trade network on logistics. Assume you did this for coffee, and a shortage of beans (or price increase) from one country led you to automatically buy from another country with cheaper/more plentiful beans. The impact would be to automatically penalize one country's farmers for trade embargoes, drought, war, or some other issue. So while logistics are a very useful tool, they should be balanced against their potential side-effects if we really want to maximize their benefit on a global scale.
Toronto has a huge road violence problem, on top of an enforcement problem. Traffic laws are almost never enforced, the police is complacent, and road violence goes unpunished. It is absurd and hard to believe, you have I see it to believe it. Drivers know that and have no problem intimidating pedestrians and cyclists because they know absolutely nothing at all will happen. Either the police won’t even bother to take the complaint seriously, they’ll turn a blind eye (can’t count the number of times I’ve seen someone break the law in their car right next to a patrol car and the cops just carried on), or they’ll get caught but not see a judge because the system is overloaded and so the charges automatically dropped. I’m not even mentioning drivers using bike lanes as a stopping lane. Toronto is pure madness and is has terrible quality of life as a result.

They do however have once a year, for about 8h, car free streets (only 4/5 but still). It’s such a delight on these days. Everyone is out and about, cops are at every intersections to turn cars away, and you can even hear the birds sing!!! But yeah that for a grand total of maybe 10 km of main streets, 16h a year.
Losses reduce the taxable income, they are not tax credits. If you're paying a 20% tax rate, you still lose 80% of those losses.
The framing of this city planning problem in my mind is like this:

The appeal of a big city is potential to connect with lots of people from different backgrounds, skills and culture. This enables richer commerce and social interactions.

This doesn't happen without huge amount of commute and lots of social gathering places like offices, schools, restaurants, malls, bars, sports, gaming, park etc.

A city fundamentally has to make it possible for a lot more number of N x k connections – where N is city population and k is number of people any one person can potentially meet – for much larger N and much larger k.

THis is the fundamental difference between a big city vs a cluster of small towns/villages which are fairly disconnected from each other. Basically, towns and villages scale down both N and k.

Okay, so the question is how do we make it possible for such a large number of N x k commutes to happen? To support large N and large k the commute has to be faster and over longer distance. It has to solve for flexibility of hours of the day and also be accessible for young/old, men/women, kids, disabled etc. There are cost affordability considerations too.

In some countries, like US, they have social culture where young and old don't live together, those with kids have different lifestyle than those without etc. Then in others like India, young and old do live together along with kids.

Solving for high N x k for mixed demographics in a large urban sprawl is fundamentally more challenging.
They are more likely to commit suicide as well.
Ok, so you’ve successfully reduced the problem space from 2^n to 2^(kn) + 2^(n-kn) , where k is the ratio of options in the two categories. That’s better, but still clearly exponential growth.
Do they? I thought they do max(3 years from launch, 18 months after sales ends in Google store), which usually amounts to 3 years.

Edit: J"ust like their predecessors, they'll get Android security updates for three years, until October 2022." says Android Police.

Considering most people don't buy it at launch, this amounts to 2-ish years of support on average.
I don't get the issue. It's just notation. You could "feel" the same way about the integral sign or fractions or about underused letters in your own alphabet.

When the greek letters are used, they usually give you a clear indication that they are "something different" from the things written. It's much either to understand that alpha, beta, gamma, delta are some counterpart to a, b, c, d than if you had to use i, j, k, l (for example).

Lowercase Xi is indeed always written horribly (like a tornado), but at least in my studies, everyone wrote it equally horribly and all in the same way.
My understanding is that this is based on the Singapore government's TraceTogether app. Vanessa Teague has been blogging analysis about the Australian government's approach:

Not sure where you are flying. In Europe, there usually is no such option. Most of the time, all you can do is pay an additional €30 or so and get a seat with more legroom. And that's it.
They have forebearance of 180 days and you can extend another 180. But this will unwind very badly because it's still due yet the renters and homeowners won't be in a position to pay lump sums. From a Planet Money episode, essentially the mortgage servicers will go bankrupt as they are the only ones that can't defer payments in the flow. You have renters, landlords, banks, mortgage servicers, investors and the federal government guarantees a lot of mortgages. It seems most plausible that homeowners who don't pay will end up with longer mortgages versus a balloon payment they won't be able to handle.
Not at this time of the year if I am reading the chart right.
The days of globalised custom hardware are numbered. Most of the hardware that are used to be customised as we know then, are actually now a commodity. For example, networking vendors always custom made (i.e. ASIC) their networking hardware especially their high end flagship products but not anymore [1]. Most of them now are just targeting commodity hardware since in the long run customization is not technically and economically feasible at the global scale.

Not really. It depends a lot on the habit. Plenty of people in Italy take the car to drive less than a km to go a shop, and then come back, especially in mid-to-small cities
> This reads to me like a person from the northern US weighing in on BBQ

The US is much larger than Italy, you know!

By the way, I qualified as "Northern" exactly for the "southern thing" reason. Pizza is an italian staple and, as such, different regions have different recipes and dough styles - not just trying to imitate the "original" version. Such original version is Neapolitan pizza, which is indeed very good.

But it's hard to bake a true Neapolitan pizza at home. Would you prepare your dough 24 hours before? Have you got the right temperature where to leave it? Does your oven reach 450°C ? So I chimed in with some suggestions to bake a good pizza at home - and, as far as I know, most people use a variation of such recipe when at home. Including people from Neaples!

I wasn't commenting on the perfect dough for the perfect Neapolitan pizza for a pizzeria; that's far beyond my competence levels.

EDIT:
after all, from my comment it COULD look like I was commenting on the "Neapolitan master" pizza recipe; that was not my intention. My bad. My suggestion is valid for HOME BAKING.

Now lets remove 4 of them:

* *

* *

I would say every one has at least a 50% reduction in the number of people close to them. On top of that, minimum distance and average distance both went up. I wouldn't be surprised if the infection rate in the second example is only 10% of the first.

Pair that with everyone wearing a mask. I have read that the infection rate goes down by 95% between two people wearing a mask in comparison to two peole wearing no mask.

Pair that with a 10-minute test [1] which everyone has to take at the airport and let only negatively tested passangers on board.

I think instead of trying to wait it out and print money, we should start to engineer ourselfes out of this crisis.

They are. Look at the stimulus plans all over the world. They’re not printing notes for these.
The alternative in Tokyo (and most other big cities), if everyone felt like cattle on public transport and decided to move to their own personal vehicle, would be an eternal gridlock of the city. You would have your own space, but you would also be stuck in your own space for hours on end barley moving forward.

Indeed! One thing that at least works on zsh is to prefix the command with a space, then the command doesn't go into the history file.

So if you do `date`, it'll end up in the history file but if you do ` date` (one space prefixed), it won't. One `clear` later and it's like the command was never run.
I haven't seen anything confirming that, either weakly or strongly. It's unlikely to be true, since most diseases don't behave that way, but we'll see.

Seems like a pretty risky thing to do.

I've always wondered why they don't do 'assigned seating' in a metro train. It is feasible to know everyone's destination station at the time of boarding. And it is feasible to know current occupancy of each car in the train. So potentially, people can be assigned to a specific car (need not be a specific seat), such that crowding in each car can be capped and more cars per train can be added without having to increase the platform length. Also, even when platform length isn't a constraint, I have seen metros running with less cars and preferring to keep it crowded. Why is that?

The three subscriptions available here in Denmark are:
SD: $11.46, HD: $14.37, UHD: $18.72 (UHD is a bit of a joke with that birate, but that is another matter).

For low income households that can be quite a lot. Combine that with Netflix having significantly less content in Denmark than the rest of the world, and it might not be such a good deal the begin with after all.

So I guess it depends on where you live and your financial situation.
