The antibody titre, a test to see if you have antibodies against a number of antigenic molecules that your own immune system used to defeat Covid-19 can be done. It is not a Covid-19 test.https://en.wikipedia.org/wiki/Antibody_titer.
A Covid-19 test has been created to see if you have RNA from the virus in your blood OR other molecules that are given off by cellular lysing as the virus reproduces and breaks open infected cells (killing them) and releasing infectious virus particles as well as many defective particles (DIPs) and excess functional viral subunits that were also made in the cell but were not used in building a virus. The virus does not have an inventory control mechanism and keeps making virus building particles as well as completed functional viruses as well as partially build particles - until the cell is lysed(broken apart and killed, releasing the whole mess)
There are several tests that look for your titer as well as several Covid-19 tests that look for Covid-19 infection indicators. If you knew the exact test you took, you can read about what it tests for and this may help you.
In theory, if you have antibodies they will resist a future infection by the same virus - the titer fades with time and the rate of fade varies,
Not so surprising. You have also the same outliers with Hong Kong and Taiwan.

- In Japan, people naturally respect social distancing. Touching someone is considered rude, everyone bows instead of shaking hands and nobody kiss.

- Almost everybody wear mask when they are sick to avoid contaminating others. They do that since way before Cornavirus and on voluntary based.

- Washing hands is common, being clean (bath culture) is part of common minimal respect.

- People listen and obey to their government.

- Last but probably very relevant: they have a completely different place of the elders in society. In Japan, the elders often live alone, sustain their life by themselves: it's a matter of proud. Even contact with their own kids is often sparse. Meaning, probably also lower risk of infection.
The people who are going to die are already in very poor health. The median age of deaths in Italy is 80 from yesterday's data. [1]

Previously it has been communicated that 99% of deaths are to people with existing health problems.

https://www.reuters.com/article/us-health-coronavirus-italy-...

There are two people in my life I expect to die of the virus: my sister who is in her late 20s, with a lifetime history of Anorexia/Bulimia, who is currently in stage 5 kidney failure. Secondly my Aunt, a lifetime smoker, who currently has terminal lung cancer.

Both of these people, speaking personally, are going to die sometime this year. Will their deaths be accounted against the Coronavirus death toll or to their underlying conditions?

Is there any point to shutting down everything for 18+ months so that they can live another few months, doing so under lockdown conditions and general panic, with nobody able to visit them? And at the end of it all, many of the people who care for them will be unemployed.
That's part of it but it's also highly popular and densely populated, both contributing factors.

I would advise you to never say to a Chinese or a Japanese that they are alike.

Excepted if you want to enrich your vocabulary with new insults in a foreign language. Many of them are nationalists, and not really appreciating each other.
I played it for about 5 hours and I just don't have any motivation to keep going. The trickle of new cards is super slow and I don't really feel like much depends on my skill at all. But I also have friends who rave about it, so maybe it's an acquired taste thing.
If it's publicly available open source, it can't contain ITAR.

If there is existing open source that doesn't contain ITAR, then that's fine because it's beyond the scope of ITAR, so ITAR doesn't apply to that scenario. [Maybe this is the case you're mentioning?]

If it is ITAR, it can't possibly be publicly available open source. [How could it be possible to have publicly-available open source software that is also restricted to being only shared with U.S. citizens?]

Of course an ITAR project could pull in publicly available open source (e.g., dependencies), but that doesn't sounds like what's being discussed here.
Not true at all. You can build two sites that look completely different without changing the CSS at all if the API of the CSS framework is low level enough, like Tailwind, Tachyons, etc.

In the end, all that matters to them is if they get a good laugh out of it, as it always has been.
The technical details are a complete mess too.

A Backpacker's Guide to Maps
Wow I'm so happy to have found this. Have you considered clubs, restaurants, cafes etc as a target market? If you wanted to start earning some revenue to host it I think there could be an opportunity more so than home users.

We had started down the track of building a basic version of this for our ski club using MS "Power Apps". Our basic process is:
1. Pre-season: estimate requirements based on previous years and do a few large orders with various suppliers for delivery to coincide with the annual food lift (we can't drive all the way to our club). Primarily this is meat and non perishables such as tinned/packaged items, toileteries and cleaning products.
2. Every few days during the season: perform a stock take of what's on-hand in the club. Send to the catering officer.
3. Catering officer orders according to his/her assessment of requirements. Mainly this will be perishables such as fruit/veges, eggs, bread, milk but later in the season may include other items
4. Items are delivered to common stock room and carried up the mountain by club members. Items are checked off the order list provided by the catering officer and added to various storage areas (fridges/freezers, store room, kitchen pantry etc).

Based on a quick run through the demo system I think grocy will meet our requirements for managing consumables.

Additionally club members staying on a particular night are assigned duties by the lodge leader e.g. breakfast dishes, vegetable prep, cooking dinner. We may be able to use the "Chores" function to help with that.

Personally for home use I would not use this because it would not be practical for our family.

Regarding an additional feature: I would recommend looking at Cozi which we use for a shared family calendar which is really valuable for us. I imagine it would be fairly trivial to add that feature to Grocy.

I'll let you know how we got on with the club. Thanks and hope that helps.
I’m about to craft my own mask before getting on a 16 hour flight home to Melbourne.

I realise it’s fairly ineffective, but I think it will help me avoid touching my mouth and face.

I have a beard anyway, which I’ve heard makes masks pretty ineffective anyway.

Wish me luck! Haha

Note: I would have bought one... but you know. Everyone else decided their need for them to sit in their cupboard at home was greater.

Even my need is lower than anyone in a medical position.

Optics at this point. Most regions in the US are transitioning to mandatory quarantine with only exceptions for food, pharmaceuticals or essential business. With both NY and CA on de facto lockdown, we will see this impact the National GDP in the coming months.

The federal government is now lifting liability restrictions on construction masks. You should see more of these in Health Care situations as they are much more widely available. [1]

"N100 and P100 Masks for Protection against Avian Flu, Swine Flu and Other Diseases The Centers for Disease Control tested N100 and P100 masks for their efficacy against avian flu, swine flu and other contagious diseases and found them to provide superior protection.

No it’s not just re-interpretation away. From a legal standpoint it’s a whole other ballpark. It breaks the fundamental principle.
Wanting to preserve art† (which people make with an expectation that it will be shared and preserved, even after their death), and waiting to preserve every detail about the minutiae of people’s lives, are very different wants.

Certainly, cultural anthropologists wish we had more preservation of life-minutiae, because it would make their own jobs easier; but most people don’t agree. Meanwhile, basically everyone agrees we should be preserving art.

† Where by “art”, I mean works made in lasting media. The preservation of performance art is... divisive, to say the least.
There's ongoing planning for how to distribute limited resources if hospitals are overwhelmed:

My guess is that the heart rests between each beat.
I've been following the developments of these ventilators pretty closely, particularly of these using a ventilator for multiple patients.

The hard part is not the ventilation mechanism itself, but the specifications.
Those ventilators must be controlled precisely, they must take into account the characteristics of COVID-19 patients. There is some overlap with ventilation for ARDS. The more you read into this subject, the more you realize how absolutely scary it is to actually design such a project.
Lots of parameters have to be taken into account.

Read on mechanical ventilation.
https://en.wikipedia.org/wiki/Mechanical_ventilation

3D printed parts that where the air flow through must be air-tight.
Based on data from China, 97% of the people who need ventilators will die anyway:

https://www.thelancet.com/journals/lancet/article/PIIS0140-6...

The Ventilator just keeps them alive for a few days, but there are other bodily systems failing and causing death.
> Just because you don't and a pre-existing condition doesn't mean you should take this lightly. Stay at home and stay away from people to stop it spreading to those that do.

Correction: known pre-existing condition. Not a lot of people get annual physicals and a lot of heart conditions are asymptomatic.

> That is, signal processing had Nyquist's rates. And typically knows there is an underlying signal. Does ml have either?

What does this question mean? Every band-limited signal has a Nyquist rate. Most signals of interest are well-contained within some finite bandwidth (e.g., human voice). Sampling above this rate will get you very little.

If you're building an ML model to process a certain class of sampled signal and you know, for example, 99% of the signal energy falls within a certain frequency range, that should guide your choice of sample rate. If you're sampling at too high a rate, your input layers may have far more parameters than are needed or useful.

Whether or not a given ML input actually contains a signal of interest doesn't seem relevant to how you sample and preprocess the signal.
The Verboseness starts to get very real when you are dealing with inlined Expressions/Functions. But maybe that's not what a normal VB.NET project has a lot of.

And, for whatever it's worth, it can encourage people to not inline which probably would be more maintainable anyway.

> As for the complaints of something being verbose, I see people constantly adding comments to close braces to indicate what it was they closed.

Lazy commenting. If you are for some reason dealing with code complex enough to need to keep track of it like that, instead take the time to comment what's happening next as a way to help the reader infer.

Because, let's face it, if it's complex enough to need to track those things, there's a decent chance it's worth leaving some explanations of what it's meant to do.
I have not seen any studies that broke it down. The studies out of China only had patients self-report other conditions.

To be fair, it's not so common to make it to your seventies without developing any of these illnesses. Being old is a risk factor for death from any cause.

We need much more specific data on younger patients with pre-existing conditions. For example, hypertension or diabetes in your forties, which is less common but not that uncommon.

We need to know who to isolate if this whole social isolation situation has to to go on for several months.

My Android Auto has limited features compared to the app, for example you cannot make a new playlist, only access existing ones.

Ultimately, it comes down to individual behavior.
Italy is looking like a “perfect storm” tragedy no matter what. The older population, combined with rapid, widespread transmission, to the point where critical cases completely overwhelm the health infrastructure, is absolutely a recipe for horrible CFR numbers like that. The fear that healthcare infrastructure elsewhere could be overwhelmed by another sudden outbreak is really the only reason experts are freaking out, as far as I know.

Also just reported today, apparently over 99% of fatalities in Italy were folks who had existing medical conditions, but I have no idea what that really tells us.

Anyway, you could be right too, maybe it’s unreasonable to guess that true IFR is an order of magnitude lower.
I recently bought Ben Eater's 6502 kit. One of the things I've been meaning to do is figure out how to get it to talk to a serial port for terminal access.

A while ago on YouTube, I watched a series where someone was restoring their IMSAI 8080 (the machine from WarGames) and learned it and the original Altair were a lot more capable than their front panels made them seem due to the S-100 expansion slots inside that sit on the bus. The first card the video showed was a terminal connection so he could send/receive commands using a VT-100 terminal (an emulator on a normal PC in this case). The cool thing I learned is that the way this worked is that the terminal board on the IMSAI would simply send the same screen info over and over again across the serial port, and it was up to the terminal to display this data on screen (making terminals like little dedicated computers themselves). I don't know how I thought this worked, but it was cool to see him debugging it.

Seems a lot easier than trying to get a direct-connected display up and running and having to figure out all the signals and colors, etc. That said, I haven't actually done this yet, so the devil may be in the details.

Hi HN, project author here. The source code and design files are on GitHub: https://github.com/74hc595/Amethyst

Documentation is lacking, sadly. My intent was to create a series of in-depth videos describing how various aspects of the system work in detail, but I'm somewhat behind on that.

For folks that say "using an ATMEGA is cheating":... I agree! That was a guiding principle behind my 6809 computer project (Ultim809)--use only period hardware and no programmable chips (apart from EPROM). Amethyst originated a bit differently. Initially it started out as a neat hack to get 8-bit color video from a non-overclocked AVR without expensive external chips. And then I discovered the mechanical keyboard community and was able to source keyswitches and keycaps, and, well, in for a penny, in for a pound.
This kind of idea is being abused to argue that people are way over-reacting to covad19. There are a large number of people with these existing conditions. I don't think this kind of information helps us. There are still lots of people under 50 getting it.
> I've adjusted to always prioritize real-time safety even if it comes at the cost of missing my turn and having to double back to get where I'm going.

This assumes that you can do that. If you are not an expert you can't possibly have the background to put things in the perspective.

This is not the issue of the ability to read and study, it's about missing variables and weighting evidence. If you don't have the background, you must spend weeks studying to get some hold of issues.

Argument from authority is fallacy of reasoning but it's not fallacy when learning and gathering relevant information. We you can reason only after you have learned the subject.

Social media is full of people who learned basic math behind SIR model and are building layman theories based on them.
This is the attitude we need collectively. It no longer matters as much to miss a turn, GPS will optimize the best route moving forward.

Some people are however, still unwilling to be delayed no matter the danger.
You've got it backwards. All non-anonymous accusations should be taken seriously. The problem in the story described by this article was the weight being given to anonymous accusations, which should not be given much weight. As a general rule, justice is well served so long as the accused have certain rights, in particular:

"In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defense."

Anonymous accusations have not played a very large role in the more dramatic cases we've seen over the last two years.

Amber Anderson is a real person. Kate Beckinsale is a real person. Angelina Jolie is a real person. All of them made public accusations against Harvey Weinstein.

E. Jean Carroll is a well-known journalist who accuses President Trump of raping her.

Andrea Constand is a real person. Her accusations against Bill Cosby were not anonymous.

Most of these people are well-known, and are putting their reputations on the line by accusing Weinstein, Trump, and Cosby. Such accusations need to be carefully investigated. In the past, these accusations have not been taken seriously and a new seriousness on these matters is overdue.
As everyone notices their packages stop arriving, comparatively few will buy into the idea that people making $17/hr are being 'exploited', especially as many people find their own working hours being reduced or eliminated.

You know, many people reading this have a pre-existing condition, so even if this is a reasonable way to interpret the data, it's not much encouragement for them.

Also, just because 99% of deaths come from people with pre-existing conditions doesn't mean that someone with no conditions has a 1% chance of dying. That's just bad math.
