Even California tap water varies immensely depending on where you are. SoCal is generally bad, which is probably related to most of their water being imported. My hometown, on the other hand, is in the Sierra's and fed by spring water that's pretty identical to the Crystal Geyser water they bottle a few mountains down. San Francisco has pretty great water too, though they did flood what was reportedly the most beautiful place in California to secure it.
It depends on the study, I've been using their reported confidence intervals. The two California studies (Santa Clara and Los Angeles) used the same kit, which has 2 false positives of 371 tests, and 10-20% false negative rate.
I'd guess smoking rates are very high in prisons. It seems smokers (even former) are much better off than non-smokers.
I use this as part of my daily workflow as a frontend developer. It saves me a ton of time instead of messing around with chrome windows. I prefer this over Sizzy because of frequent updates and better synchronized scroll support.

I do wish the reloading time would be faster but I understand that when you reload 7-10 chromium windows at the same time, it's bound to be a bit slow.
I don’t think neither of these sayings are in themselves contradictory. The first could be translated as “I trust your work ethics, but I also know that your human nature will lead you to perform better under supervision”. The second basically says: “God has my back on a number of things, but She also expects me to do my part”.
Tangent, but this reminds me of this great talk by Matt Godbolt from CppCon 2017: “What Has My Compiler Done for Me Lately? Unbolting the Compiler's Lid”

I need this on my desk.
Does anybody know the false positive rate of the test?

Could this be an artifact of that plus low actual incidence like:

- False positive rate of 10%

- 100 tests

- 1 true positives. All with symptoms

- 9 false positives. All without symptoms (duh!)

Headline: "90% asymptomatic!"

Truth: "Shitty test procedure!"

Yes, yes, I know you know this. Do you think people doing tests and writing headlines know this?

What is the false positive rate?

You have to account for events like the Diamond Princess, if you want to run with that story.
Not sure I follow. I confess I'm biased in thinking we could have locked down nursing homes and shaved a large chunk of deaths. Catch is, we should have done that in January.
The WHO says that we can't assume someone is 100% guaranteed to be immune when they have antibodies. That's true, and it's an important flaw in the idea of immunity passports that they're tackling - you couldn't send people with immunity passports into quarantined nursing homes or allow them to attend potential superspreading events.

Herd immunity doesn't require perfect immunity or a 100% guarantee of it. No reasonable expert doubts that herd immunity is possible, although some argue it's too costly.
The benefit they could derive is perhaps the same. However, they cannot prioritize it the same way as others with a higher budget.
It’s not like this is the first population that has been nearly exhaustively tested. There was the cruise ship, there was the navy ship, etc. Those have shown between <20% (among the elderly cruise ship demographic) to 60% (among healthy soldiers) asymptomatic.

This certainly adds another data point, but I wouldn’t throw conventional wisdom out the window yet.

I disagree. I negotiate all the time, and often even get companies to use my contract or at least incorporate many of my terms.

Edit: If you aren't ready to say "sorry we couldn't make a deal" and bail, you'll never know what finance is willing to do. They have a lot more time than you.

Edit 2: biggest lesson for me: "these are our standard terms, we don't negotiate them" is just words! You get to use your words back. That's negotiating. I can say "I always accept payment in full prior to starting". Neither are laws of physics, right?
Plugging the 96% into New York numbers results in 155,000 / 4 * 100 = 3,875,000 infected people in NYC, or about half the population.

This is assuming that tests in NYC currently include every infected and symptomatic person. Considering the official advice for people with mild symptoms is to stay home (and not seek a test), that assumption is ... optimistic.

It also wouldn't fit with the anti-body tests that have been done in NYC that showed figures closer to 15-20%.

So I'd expect about 1/2 to 2/3 of these 96% to develop symptoms within the next week.

The other possibility is the prison population not being representative of the general population. That's probably true in terms of fatality rates, because they are younger. I'm not entirely sure if that age imbalance is just as strong for any symptoms as it is for risk of hospitalisation and death.
Not sure why I am getting downvoted, I guess covid-19 shaming is a thing. From what I've read people who appear to get it again is actually just a relapse of the original infection[1].

This article is a real failure in the rule of Profile Before Optimizing. Changing your editor or whatever is a micro-optimization. Among professions where typing is involved, programmers type the least number of keystrokes. Secretaries and data entry clerks type much more and often much faster than programmers. Also, a lot of typing is not even characters into the editor but keyboard shortcuts.

The real time killers are mental--fatigue, boredom, procrastination, anxiety, and so on. How many hours do you spend a week on HN or social media? How long are you going to take to do that big refactor you've been putting off? How long do you spend in useless meetings or chats you're not persuasive enough to get out of? At what point is RTFMing too long procrastination? How long do you spend watching N*tflix at home if you really want to get that side project done?

The bottleneck is never your typing speed or your editor commands. That is snake oil by script kiddies trying to sell you something.

Yea, I agree that the case counts are very different between regions. I think the more interesting column is the IFR estimate based on the antibody study results, since dead is dead as you say.

It is interesting though that the median undercount is converging to ~10-20x. Perhaps the protocols across regions are similar enough that the confirmed case counts are somewhat comparable.
I wanted to create something that would help people get paid for creating the things they love.

Why would a real-time OS help at all with latency? All RT means is that the latency can be reliably upper-bounded (but note that that upper bound might be very high/slow), it doesn't mean that the latency will be reduced. Real-time OSs aren't faster.
During times when the world isn't falling apart, I teach Scratch to kids on weekends: https://scratch.mit.edu/

I don't pretend that Scratch's drag-and-drop block paradigm is a viable replacement for text-based programming, but I do think it demonstrates that there might be a text-like system we could create that would free us from keyboards, without reducing our source code to piles of spaghetti.

Also, is declarative programming typically mappable to a visual paradigm without severe compromise? Think of all the applications that produce non-executable documents; don't they factor into the visual programming discussion?

UK accused of paying too much attention to epidemiologists over other experts
I'm in a high risk category with an incurable respiratory condition. I'm convinced I've already had it and I'm mostly recovered now.

I was mostly asymptomatic. The biggest thing going on was that I was very tired, which was also something easily explained by other things going on, so I was basically already on the mend before I concluded I must have had it.

I believe we are barking up the wrong tree. We are looking for respiratory distress because it leads to low oxygen levels. I think we need to be looking more at what it does to the blood. Fortunately, some doctors are looking in that direction, but I think not enough, probably.

My symptoms were similar to anemia. It's easily missed because you mostly lack energy.

Again, there can be lots of reasons a person has low energy. It can be quite hard to say "Clearly, this symptom is indicative of Coronavirus."

So I suspect a lot of people will never be overtly symptomatic in the ways the world is looking for with its huge focus on lung issues.
Applied for EIDL 3/18 w/ application number 20001.... was in the first group.

Applied again, twice, as two successive systems had to be deployed after the first crashed.

I've received $15,000 as an advance. The EIDL loan is critical to our survival, but my guess is the program will be void of funds soon, and well before I see any money.

I did get PPP funds. This will keep my people on the payroll another two months though its my sense - and I want to be wrong - that the economic crisis will continue for much longer.

Congress (namely Sen. Rubio who managed the Cares legislation) was a Miami lawyer for an influential law firm there who soon after starting practice entered politics having been groomed for the role (as I understand it). He has next to zero business experience.

The administration had the right priorities, but Congress is incompetent. The administration will get all the blame. Nobody will hold Congress accountable, and even fewer will hold China accountable.

The whole chain of responsibility is hopelessly broken.
I've done a lot of work testing this type of latency in web browsers: https://google.github.io/latency-benchmark/

On Windows, DWM's display compositing adds one frame of latency to every window on screen. It's not possible to render a dragged object in any window that sticks to the mouse cursor without at least one frame of latency.

But when you drag whole windows around they do stick to the mouse cursor with apparently zero frames of latency; how does DWM do it? Easy, they cheat by disabling the hardware mouse overlay during window dragging so that the mouse cursor gets that extra frame of latency too. You can prove this by enabling "Night light" in settings; watch the mouse cursor change colors as it transitions from hardware overlay to software rendering when you start dragging a window.
I've read that asymptomatic carriers are though to be less infectious than those with symptoms because of the lower concentration of virus in the saliva. Also, many virologists mentioned in recent texts that the initial concentration of the virus you receive can affect how sick you'll get - the more viruses you're exposed to, the faster they can invade the body and the more severe it will get.

Can those two facts be combined into a theory that asymptomatic carriers are more likely to produce more mild and asymptomatic cases?

Don't know if it makes any sense (probably not), but it would certainly explain how in some closed environments there's a prevalence for mild cases, while in others there's a plenty of very sick people, regardless of the age.
No they are not. They are for revenge and punishment!

The downvote keep the party line with what majority is saying is the most annoying thing about this site, but I don't know the alternative. Certainly trolls and the ill informed need to be discouraged but it's always annoying to see a legitimate reasoned opinion greyed out.

Does anyone know if there's been any studies on those who have taken no medications at all in past X days vs those that take any (either OTC or otherwise) and those with and without symptoms?

I ask because I'd assume drug use would be lower in prisons, and among those in poorer countries. I'm just wondering if a particular set of drugs could accelerate/make this worse?

That said, I'm not sure this is even possible to obtain metrics on, it'd just be interesting to see if there's any type of correlation to rule out. I realize there's been conflicting studies on whether certain heart meds may accelerate, but I've not been able to find anything about any drugs use whatsoever.
I didn’t have the patience to read all the way through this article. Something about the writing really drove me crazy. I just want a basic explanation of what this is. This TechCrunch article gets to the point much more quickly. https://techcrunch.com/2020/04/18/clubhouse-app-chat-rooms/
As a Canadian, I'm shaking my head at our officials who said "we do know that asymptomatic people are not the key driver of epidemics" as a response to concerns back in January of the potential for the virus to grow in our country via incoming travelers who came from hot spots and were not screened or forced to isolate if they expressed no symptoms.

Now our long term care facilities are being overrun with cases potentially because we waited until deaths piled up before testing asymptomatic caretakers for the virus.
The asymptomatic rate being that high and that many people being infected implies three things.

1) that the asymptomatic rate for this Coronavirus is much higher than other Coronaviruses.

2) but at the same time, it's more deadly than most Coronaviruses.

3) and it's also the R0 is much higher than other Coronaviruses.

Isn't it more likely there's a testing issue? This seems a lot like a person that runs a SQL query that overturns all established data at a business, and instead of first assuming that their query is wrong, they instead assume everyone at the business is wrong.

I'm not saying the tests are inaccurate. I'm saying when you get highly conflicting data that has critical implications, you shouldn't jump to conclusions. And you should prepare for the worst case, not assume the best.
Is it? I don't have a retail shop and a menu or anything; I need to have some conversation to propose the work and timeline. That's all I'm saying. A couple of free hours of estimating and discovery.

This is correct. I post the same thing every time one of these JS dependency hell issues pops up, but it's the case because it's true: The problem is the lack of a standard library. It's not that people don't know how to write a left-pad function, it's that it's dumb to rewrite it in every project and then remember what order you put the arguments in, etc. So people standardize, but they're standardizing on millions of different little packages.

I think the effort that goes into all the JS syntax and module changes would be better put into developing a solid standard library first.

Looks like a solid survey of the state of the art, as one would expect from Boneh and Shoup. Given that this is about applied crypto, I would like to see a chapter or sub-chapter devoted to discussing the usability of some real world cryptosystems and their implications. I think it’s something of a “black art” in crypto, but often ends up with as large a practical impact in practice as what crypto algorithms are being used. Would be nice to see it treated with the same kind of rigor as the more technical aspects of cryptography.

Not sure why you are being downvoted:

https://www.oxfordbiosystems.com/COVID-19-Rapid-test

"In order to test the detection sensitivity and specificity of the COVID-19 IgG-IgM combined antibody test, blood samples were collected from COVID-19 patients from multiple hospitals and Chinese CDC laboratories. The tests were done separately at each site. A total of 525 cases were tested: 397 (positive) clinically confirmed (including PCR test) SARS-CoV-2-infected patients and 128 non- SARS-CoV-2-infected patients (128 negative). The testing results of vein blood without viral inactivation were summarized in the Table 1. Of the 397 blood samples from SARS-CoV-2-infected patients, 352 tested positive, resulting in a sensitivity of 88.66%. Twelve of the blood samples from the 128 non-SARS-CoV-2 infection patients tested positive, generating a specificity of 90.63%."

That gives us 62% false positive ratio according to (where a study finds the prevalence to be 6% of subjects using the test):

http://vassarstats.net/clin2.html

In some cases we have research being carried out with such low positive results that they can entirely be accounted for by the low specificity. So for example if you took samples from 100 people, based on 90% specificity, even if everyone had never had corona, 10 could be found positive.

What I don't like about P2P is that it depends on peers being online at the same time, and it exposes metadata to the whole network instead of only law enforcement and sophisticated / well-funded attackers.
" Do you think people doing tests know this?"

Probably.

" Do you think people writing headlines know this?"

Maybe, but unlikely that they care, if the result is a flashing headline.
The author picked a case in which compilers can be faster, because it turns out to be the sort of code that compilers are usually optimising for; code that contains plenty of scientific/numerical computations. Thus the result is not so suprising.

On the other hand, with branchy "business logic"/general-purpose code and algorithms that can't really be vectorised, it's pretty easy to beat a compiler with handwritten Asm --- on speed, size, or often both.
> Is anybody following up on stories like this?

The best follow-up we have is from the cruise ship, where at the time of testing more than half of those who tested positive were asymptomatic, but ultimately something like 80% of the confirmed infected ended up with symptoms.
We went to agriculture because otherwise we'd starve. Mechanized agriculture has virtually eliminated starvation. I don't want to live like medieval people did. If you think their lives were better because of no machines, I frankly cannot understand that.

My lawn is mostly wild, I just mow it once a month or so to keep it from being an impenetrable tangle of blackberry pushes about 8 feet high. Cutting those bushes by hand is an exhausting process. I finally got a weed whacker and replaced the string on it with a blade, which knocks them down to a size where the mower can finish them off.

Much as I dislike gardening, I dislike being buried in blackberry bushes even more. I also keep the brush down around the house because it's a fire hazard, and it gives cover for mice to get in the house, and provides avenues for insects to get in the house.

Grass also does a good job of keeping the erosion of the hill I'm on down - blackberries don't. Keeping the grass from going to seed reduces my problems with being allergic to grass pollen.

So yes, there are reasons other than impressing the neighbors.

If I ever do sell the joint, however, I'll have to have it properly landscaped, as I'm sure that'll increase the value of the property far more than it would cost.

Yes, for other minorities, instead of observing the rise in the educational and financial success of Asian Americans and using it as a motivational example, in some ways what Asian Americans took away from Jewish success in America, they point to Asian Americans being too competitive and try to enact racist quotas so Asians only compete with one another.

They took the easy way out. They can make a huge movement out of going into their own communities and educating their members on the value of hard work and knowledge and encouraging their own kids to excel from a very early age in the same way asian parents do. They can attach an underdog narrative to it and show the world that through sheer motivation and will power they were able to, as a community, in a couple generations, rise up and improve themselves in a radical way.
Instead they allocate their time to protesting and complaining that the system is unfair.

Ask HN: What motivated you to get into ML?
I've been 5 years in FAANG, "Jack of all trades, master of none" engineer with frontend/backed experience.

Wanting to get deep into a field, ML seemed like the one with the most potential for positive impact on the world.

I've been struggling with sticking to learning ML as a lot of projects seem to be some clarification (cat vs dogs, etc.) or a regression task (predict sales count, ..).

What was your motivation for sticking to ML? Did you find the projects mentioned above interesting?
You're missing that nearly any purchase of business space will also be funded by debt etc.
Your sheet is interesting. Looking at it, the IFR varies from 1.66% down to .11% and the 0.11% is for the Santa Clara, which many considered rather suspect.

The 1.66%, otoh, seems reasonably in line or at least compatible with what's been observed in Korea and elsewhere.

Given age is going to skew things a good deal, it seems like a picture is emerging but not that new a picture. An IFR of even 1% is pretty bad, especially given these statistics show how infectious this virus is.
No, that can’t be the case here, because a shockingly large proportion of people tested positive according to the article. (Thus, either the false positives are negligible, or the test employed has a an astronomical false positive rate (bad specificity)).
The bill was rushed and people who needed it the least ended up profiting more than people who needed it the most and weren't successful in applying. The fault is on the people who designed that bill. The whole "please give back the money" political posturing, is just that, political posturing.
