This is bad. I've been graphing the exp curve for Italy, UK and USA and the USA curve is fearsomely steep. Italy has more cases now but the USA is growing fastest and looks like it will match Italy's on ~March 28th (looking at the most recent 10 points, see below)

The rate of growth in the USA, extrapolated, is just huge. Looking at the whole curve it does not match an exponential well, I think the early part is skewing it. If we take the last 10 data points, they fall very well onto the curves for all 3 countries, and that curve for the USA is horrific. I'm not an epidemiologist nor statistican so it would be irresponsible to put my predicted figures here, but christ, if I'm right the US is going to be reeling in just a few day.

Edit: @mnl below has pointed out that infection is not an exponential but on the whole a logistics curve (s-shaped curve https://en.wikipedia.org/wiki/Logistic_function). He is correct. However in early stages I believe an exponential MAY be a decent approximation (and I'm reading up on it now). However, the inflection in the 'S' (where new infections would start to slow down) would be expected to be at far higher figures than those I'm looking at - a few tens of thousands of reported infections per country currently - and it's not even close to that (populations of multiple millions in each country).

Most people (and most people who advice the public in the US) doesn't take this serious enough.

One of the foremost experts in epidemiology in the US Michael T. Osterholm said on Joe Rogan (AFAIKR) 6-12 months for the virus to go away, up to 5 years for a vaccine and that it would return in China when people start behaving normally again. This isn't something that will go away in a few weeks or months.

In "Deadliest Enemy: Our War Against Killer Germs" he also predicted a Corona virus coming from China.

In a months time the US will take the place of Italy and see the healthsystem crash.
I'm a little confused at your calculations.

With a population size of 1000 and with 0.01% of the population infected (i.e. 1 individual) with this test we'd get 82 false positives and 0.979 true positives.

For every true positive result in your population, you'll have 8 false positive results and 0,021 false negatives.

Being one of those reasonable people who has not fallen for the complete lockdown argument, I feel that the ball is rolling and no argument can reduce the measures right now.
In Denmark there are 42 people requiring ICU care and 13 deaths. Just two years ago more than 1.600 died due to the common flu, but that hardly got any coverage nor any of the counter-measures being employed right now.

If I should find some positive in this over-response, that would be the benefit for the environment due to less pollution.
If we could reduce emissions to the current level, the climate would be so much better for it.
I think the iPad is the single most polarising product in the Apple ecosystem. I think the 'not a computer' marketing is pretty well judged. For many people it really can't replace a laptop, but for others like me it's so much better than a laptop could ever be due to the form factor and the situations I can use it in.

When writing this I wrote some phrases like "It's just not good at many of the tasks people use laptops for", then had to try and rewrite that a few times. The thing is there are a whole slew of tasks that sound like they are the same, but how and where you do them makes a huge difference. How you do them on an iPad is completely different to how you do them on a laptop, and that breaks some people's work flow or simplifies and streamlines otherwise very painful work flows for others. I use my iPad heavily for writing and scripting, but I do a lot of that on the train or in all sorts of ad-hoc situations where a laptop would be a real nuisance. Hence I don't use a keyboard case either. It works for me but absolutely would not work for a lot of others.

Saw this a few times on HN, but immediately thought of it and feel its an appropriate response to your friend.

"I thought using loops was cheating, so I programmed my own using samples. I then thought using samples was cheating, so I recorded real drums. I then thought that programming it was cheating, so I learned to play drums for real. I then thought using bought drums was cheating, so I learned to make my own. I then thought using premade skins was cheating, so I killed a goat and skinned it. I then thought that that was cheating too, so I grew my own goat from a baby goat. I also think that is cheating, but I’m not sure where to go from here. I haven’t made any music lately, what with the goat farming and all."

Yes I love having to pay Apple to distribute my apps with a manual review at every update, to get them reject updates for reasons such as "you mentioned Android" or "we need an user account to test your app to check whether you write Android anywhere".

If you really believe theres nothing more to be learned in those two years left then absolutely drop out but remember that everyone who didn't will have those extra two years and the qualification that proves they actually know what they're talking about.

That's nice, but one such person can shut down the entire production line in some factory, or the hospital department. (happened already in my country) Such people have disproportionate effect on the economy.
Give it time. It takes about a week to bootstrap a starter. You need to feed it every day by giving it equal amounts fresh water & flour and discarding about half of the starter.

Once you have a stable starter, it's very forgiving. I tend to use pretty much all of it and then toss some flour/water into the container it used to be in. The little starter left behind in the container mixes with the flour and water and it lives on. I keep it in the fridge when I don't need it.

I used to agree with that sentiment.

Then one day I saw a stock clearance offer and bought an Ipad because the price was so good it was a steal.

Then another day I added three pdf books to ibooks so I could read it on vacations, then three more, then ten, then twenty.

I also use it for note taking and sketches. The pencil and the ipad is an old model now but I love it.

Then I stated using it for programming with my own side loaded apps that connect with a big computer.

Then for minor things like controlling my 3D printers, for showing something to someone(work colleagues) you can do it while walking which is very useful.

So the thing only does three things for me, but in those things the thing is essential.
Testing should perhaps not be done at home, at all.

True positives could be sent for PCR testing to confirm whether they are infected or already cleared.

Negatives that show symptoms could likewise be sent for PCR testing.

This way, you'd massively reduce the strain on PCR testing resources.
Coming to a Country Near You: A Russian Nuclear Power Plant
From what I read in this article and other sources, performing more tests seems to be a very promising approach to get this pandemic under control.

The number of positive tests and death rates are published every day on all channels. I wish the number of performed tests would be also published daily. What gets measured gets managed.

I wonder what limits the number of tests that can be performed. How much would it cost to ramp up testing capabilities so that every person with symptoms can be tested? How much to increase it to a level that everyone can be tested?
I had to give it 3-4 days before I got some activity. Any flour should work as long as it is unbleached. I've had good success with just Sainsbury's strong white bread flour. It has given me a fragrant peachy starter.
Amancio Ortega, Spanish self made billionaire (started as shirts delivery boy at 13yo, now 6th in Forbes list), has announced he will deliver 300k masks per week, will use his huge worldwide logistic network to support the government provisioning, and will start producing protective vests in his factories.
For the right combination of budget, application and team you can get a custom solution with much lower latency. Back in the days my team beat Solarflare hands down, but only for a single application. Don't remember the total number, but each additional 4 bytes of the payload added 5-7ns, IIRC.
Yes - absolute criminal negligence in the US and UK. Possibly Australia too.

The problem isn't just that a lot of people will die because the health system is swamped. That's hardly good news, but when you have a high peak you have a lot of people ill at the same time. And that means you run the risk of losing a significant percentage of critical workers in essential services including food, utilities, logistics, and IT.

Some will die, some will "just" be very ill and unable to work for 2-4 weeks. If you're lucky the numbers of seriously ill will be low enough to keep things running. Beyond that you're on a scale from frightening inconvenience and breakdown in some locations to the economic equivalent of critical organ failure.

Pushing any country through this is a huge and utterly irresponsible risk.

According to npr there is a shortage of melt blown fabric to make the masks, and it takes six months to build the machine to produce such product. I'm skeptical of all these places claiming to produce masks, that they are actually the quality and performance they claim.

TP + FN means true positives plus false negatives, that is the number of deseased people. P should be the number of people that gives positive in the test, since TP means true positive in that sense.

Also TP + FN = Prevalence of the desease, but using P for prevalence and for positive creates a lot of confusion in a wikipedia page to explain a concept.

My plea is that I don't want people to get confused. On top of it there is a warning on that page of wikipedia: This article may be too technical for most readers to understand. I couldn't understand why they used that notation. So I ask to delete that page because is going to confuse people.

> The most important thing is that you have a consistent way of measuring yeast amounts

Well, when sharing recipes, it certainly help if _we_ have a consistent way of measuring amounts. 1/12th teaspoon sounds very hard to actually measure in real life and some teaspoons have different sizes. Using grams (weight) or milliliters (volume) would make it much easier to replicate + it gets easier to multiply the recipe in your head.

So I agree, let's start using international measurements for recipes please!
> There's nothing sad about it.

Why? It's a drop-in replacement for Objective-C that allowed you to dip into C and C++ code in the same code file, even in one function.

Now Swift is faster for most higher level scenarios a front-end developer deals with but it's slower than the C performance Objective-C allowed.

It does in the overwhelming majority of real cases.
That's a very good point, and the lack of tests had a secondary effect. Nobody here took it very seriously at first, because the numbers were very low.
When I was at university, the head of admissions position at the school of physics was forced on someone who didn't want it. So he used it as an opportunity for an experiment.

He offered a place to everyone who applied. People with low grades, people without the maths prerequisite, anyone really.

Our intake swelled from about 60 students to almost 100. The ones without maths really struggled. Many dropped out.

But to him that was the whole point: if you're smart/hungry/hardworking enough to pass you'd pass. If you weren't, you'd drop out or fail. Either way, why should he try to "pick winners"? This way winners without math prereq (or whatever) still hey a chance.

That changed the way I thought about admissions as 2 of the extra 30 got a degree they never gave had a chance at otherwise.

As a moral issue, we are choosing to continue to pay our every-other-week house cleaner to not clean our house. Everyone else is getting paid iff they provide current goods/services. We have our own financial survival to look out for until more is clear about the economic outlook.
This is key. We really can't compare countries confirmed case numbers directly because they are operating very different testing programmes. Just look at Germany. More confirmed cases than the USA, but a quarter of the deaths. Germany also has 80% as many cases as Spain, but about 5% as many deaths. All that, without a severe lockdown.

Clearly something completely different is going on there than in many other countries, and it seems they have an extremely effective and well organised testing system. They're testing about 160,000 people a week. In comparison, the UK to date has only tested around 50,000 people in total so no wonder our case numbers are far lower, even though we have double the number of deaths.

So Germany is an outlier, but it just goes to show even for other countries you can't just compare the curves and draw any definitive conclusions without also looking at the testing regime. This is where the experts with their detailed population models and simulation tools come in.

I think D didn't gain the momentum because of GC. O/B system is interesting but makes the syntax ugly (at least in Rust's case).

If you read the article, Dr Brilliant [sic] says 12-18 months most likely for a vaccine?
Which is scary because Japan seems to have had the virus for a long time and is hardly testing at all. Really makes me wonder how the Olympics will or won't look.
I personally strongly disagree with:

Functions or instructions that can cause the code to panic at runtime must not be used.

First of all, they kind of dodge this later by saying "Array indexing must be properly tested" (else it can panic) -- everyone thinks they write code which is "properly tested".

Personally, I often write panicing code -- if the code gets in a state where I have no idea how to fix it, I panic. For some code it is important it does quit, but I'd much prefer more code paniced than tried to carry on and ended up creating other problems.

Also, in rust if we don't want to panic we need to never use array indexing and never use integer division, just to start.

Of course, it's fine to write code which plans to never panic, but I think it would be better to say "Have a formal 'panic plan'", where either one panics early, or tries to never panic.
