Disable Bluetooth. Use a cabled connection if you need headphones/mic.

If you need Bluetooth then check whether your phone has the same Broadcom driver - you might be fine depending on hardware. Or check if you can install open source firmware that includes a fixed driver.

There are other things you can do depending on device.
> The false positive rate of lockdowns is 100%.

If that were true lockdowns would make absolutely no difference in R0. Clearly, they do make a difference.
I had to search out one of these TP startups in order to find any. My house is in full isolation mode: not trips to supermarkets, we piece together our grocery shopping from multiple online options since most are out of stock on at least 1/3 of our orders, and shopping online like this we can never get any toilet paper. None at all.

So about 4 weeks ago I orders from gono2. They aren't taking more subscriptions, but will allow one-off pre-orders for when they have stock. I have an order coming in about 2 weeks, and we hopefully have just enough to make it til then. If not, we have baby wipes for our young'un in diapers that will see us through.
On the other hand, we found boardgamearena.com very, very polished after trying out yucata.de and brettspielwelt.de.
I've found that if you delete /etc/netplan (just making sure this is at least empty seems to be the most important part) and /var/run/systemd/network netplan doesn't really seem to do anything. My org has been using systemd-networkd directly after doing that for about a year and it's working fine for us.
I also don't think this particular test is an antibody test? It seems that this test detects viral particles based on:

"The most proven and ready to scale technology is based on surface plasmon resonance. It’s able to detect even a very small number of viral particles, which is very important because we want to detect everyone who is contagious"

(6th paragraph in the "A third solution" paragraph)
I feel like FLCL is about a hell of a lot of things, it just is not very interesting in really articulating them in great detail.

It's still a hell of a thing worth watching, I should really get around to watching the sequels sometime.
...or add exterior air bags, perhaps?

edit: upon googling the subject, apparently some companies are already working on it. I'm not surprised.
I totally agree with you. In fact, some branches of software engineering do have equally high standards as other engineering fields. If you write the software for a medical device or an airplane, you better make sure it doesn't have any critical bugs, otherwise people will die. If you write audio software for professional musicians, you better make sure that it doesn't have any critical bugs, so you don't ruin a live show. I think people claiming that nobody can write bug free code and you shouldn't even try simply work in environments where failures don't cause irreversible harm.
It's a great apple - they're popular in England. My own favourite is probably Worcester Pearmain. England is blessed with a huge variety of apple types, it's just a shame that the supermarkets concentrate on a fairly small selection.

Well... That's truly unfortunate, but on a pragmatic level it really shouldn't be an issue; Void, by necessity, is no longer dependent on any one person after the last time he left. I'd only worry if it implied deeper organizational issues, which is possible but I don't see any obvious evidence.
In C++, you can use templates to pattern match/duck type interfaces at compile time.

So "template<typename PrincType> void princOk(PrincType& p, Stuff& stuff) {p.doThing(stuff); }" would map properly as long as doThing was implemented in all the different classes. You don't actually need an interface or base class for it to work.

The rest of the dynamic mapping is faster by calling switch() on an enum class member and than static_cast rather than relying on dynamic_cast.
I don't think this tracks.

What do you do if someone denies the test? You can deny them entry, but if they protest or decide to force the issue, then the police have to deal with it. Then if the police get sick, they have to self-quarantine, and what do you do when you don't have the power to enforce the test?

Even if we managed to dress up our entire police force in hazmat suits to reduce the risk of infection, they can still infect people out and around the building. Turning away someone doesn't mean we're reducing the R0, we're just moving someone that's infected around. Given that there are asymptomatic people (and a certain number of people that would likely claim the test is a false positive or fake), all we're really doing is encouraging more people to gather in a single location as a potential infection vector.

Let's assume next then that somehow we had an automated solution. All the doors to said buildings are locked unless you complete a saliva test to go through. Barring the huge logistical concerns, we're still dealing with potentially infected people spreading the virus on surfaces and areas that people are travelling to and from.

Tech isn't going to save us from COVID-19.
>> This is still a common design pattern for satellites, referred to as the "bent pipe" model since

If it is a communications satellite. It is also a common design pattern for military satellites to be mislabeled as "communications" when they actually do other things. So too is it common for "communications" to also cover intercept of enemy communications.

What happens when scientists admit error
There's a bit of gish gallop and vitriol here.

First, the .75% mortality rate is a one-time hit. It likely pulls some deaths forward, so the incremental death rate is maybe .5% in a single year. Again, this is terrible, and sad, but we should be mindful and accurate with numbers.

Second, people make lots of choices that increase their mortality risk by .5%. For example, lots of people eat at McDonald's on a regular basis, which certainly increases your lifetime mortality risk by .5%. And other people don't exercise at all. 30 minutes of jogging a day will lower your mortality by at least 1%, likely a lot more [1]. But we don't pass laws to force everyone to jog for 30 minutes a day.

With the new data, which is showing that mortality rates from covid-19 are not like smallpox 2.0, we should adjust our response to be more in line with responses to comparable risks.

The median Bay Area household cannot afford to buy a house, yes, but that does not mean that those buying houses are significantly wealthier. The Bay is far, far richer than you can imagine.

Buying a house for $1M is firmly middle class status. True lower class people simply cannot afford to live in the Bay at all.

To be in the top 1% in the Bay Area you have to make close $1M per year.

Indeed! And this is not necessarily a downside, sometimes you want to preserve the flags.

Intell added the MULX instruction that is similar to MUL, except that it doesn't touch the flags. It's very useful in bignum math.
I still remember when a PM distributed this diagram as recipe for ultimate happiness. I only could think "are you kidding?". when you look at details nothing makes sense or it's just a bunch of words that sound and look good.

Tech guys like to do the same. One director once showed the "architecture" of the next big thing in our department. It was a bunch off boxes with "authentication", "JSON", "distributed", "NOSQL", "JSON", "Roles", "reliability" and twenty other buzzwords. He asked for estimates how long it would take. after asking what this means and what it's supposed to do I was out of the planning. Two years later there are still two guys developing it but nobody knows what it does.

Even if the percentage of women in STEM has gone up do you disagree with the assertion that: "Women on average are more interested to work with people than men"?

I believe that while societal factors have contributed to women pursuing specific career paths, if one was to factor that out or course-correct in some way you'd still see less women in engineering due to their preferences.

Is it wrong to feel like on average men and women are different in their preferences? This is not to say that there are not men who exhibit traditionally female preferences and vice versa. If we could undo the last 2000 years of societal programming (and run a new experiment) I think we'd see different preferences in men and women then we see today, but I seriously doubt you'd see 50/50 engagement across the board because men and women are distinct - although they certainly share a common set of attributes.

That question is banned until a board meeting comes up and your owners asks you "What are your plans for the products the next quarter, misters CEO and CTO"?

If you babble around saying plans and deadlines are for suckers and that things will happen when they will happen, I am not sure they will keep paying you and your team's salaries for long. This new contrarian cargo cult of waving away any kind of medium-term planning or estimation is hurting businesses as much, if not more, as when all projects were waterfalled and timeboxed to death.

Yes, estimating is hard to get right. No, it does not mean we should simply get rid of it. Because engineers do not live in a little bubble of code: there is usually a whole company around them who need insight into what is getting built and when they can expect it. And anybody who believes that asking this question is too much or intrusive has never worked in a non-engineering position, or think of themself too much.
not only critical-- lots of jobs are critical (janitor) but don't pay much. This is also hazardous right now. Look at some of the worst states like NJ & NY right now: There's mini outbreaks at a lot of supermarkets.
> I think that people's fears of a lack of food in first world countries are overblown, but people are still afraid.

I'd love to think that, but as I follow supply chain news these days, it dawns on me that economy is surprisingly complicated. Just as a random example from today, I wouldn't ever think that there may be issues in food production in the US because of shortage of carbon dioxide, ultimately caused by ethanol manufacturing shutting down, which is tied to all the oil being dumped on the market. Or another example, shortages of flour and yeast in stores were not caused by the shortage of actual product, but of commercial-sized packaging.

I like to think that my region will be fine, food-wise. But I worry that some non-obvious links in the food supply chain get broken and the situation will rapidly deteriorate. So even as we bake our own bread and pizzas now, I'm slowly increasing the supply of flour anyway (among other foodstuffs).
>How do you feel to find yourself as the subject of such rhetoric

I'm the son of immigrants and if anyone implied that most of the immigrants from my third world country of origin were, let's say, underachievers, I wouldn't have any problem with it, because this hypersensitivity to anything remotely critical of people from other nations or cultures is an inane western cultural norm. I assure you that liberal white people are far more offended on anyone's behalf than actual minorities.

>How do you feel to find yourself as the subject of such rhetoric? I'm guessing, not very good. You're probably feeling something along the lines of 'what did I do to you, I'm just living my life and you come along and start saying these things about me.'

This is absolutely childish reasoning. What Trump says about the general state of immigrants coming from my country of origin does not reflect on me personally.

Moreover, what he's saying is objectively true, in that the people crossing the border illegally are not exactly doctors and scientists with post graduate degrees. They are mostly a burden on our infrastructure and all that about how they contribute more than they take is absolute hogwash...but that's another discussion.

>What he's 'fighting back' against appears to the plain reports of his own behavior.

>I formed my negative opinion of Trump's remarks at his press conference yesterday based upon listening to them on the White house's youtube channel.

Do you honestly think it's reasonable that some 95% of headlines about Trump are negative? Do you truly believe that every single thing he does is negative? I challenge you to find a single positive headline from CNN or MSNBC or the like from the last few years that isn't an editorial.

>Seems like you might be experiencing a little cognitive bias of your own.

My cognitive bias is that statistically for Trump to make the wrong call as often as the media claims he does, he'd have to do so deliberately. As in it would take effort and skill to be wrong this often.

>What hatred

Please. You want to pretend people online aren't rabidly against Trump? Even this latest gaffe, coverage of which is exclusively negative, could trivially be interpreted as listening and deferring to suggestions from experts. But you won't find that valid take on "reputable" media.

I'm not sure new state powers would be required. The state already can (and does and should) compel people who are known to be infected to be quarantined, or at least self-isolated. As far as testing, companies can already require employees to be tested as a requirement to work. A lot of companies already do drug testing of employees, something I actually don't agree with in most cases, but it's already a norm. In normal times they likely won't have sufficient incentive to do virus testing though, and so probably wouldn't given the cost.

But during an outbreak, the ability to roll that kind of thing out, especially in workplaces with vulnerable populations (like senior care homes and hospitals) or necessarily close working conditions (like restaurant kitchens or some factories) could certainly be a game-changer. And that just seems entirely reasonable to me. There's a outbreak happening, so in order to enter [place where transmission would likely occur] you have to be tested first. If found to be infected, you must isolate. Otherwise, you'd be knowingly exposing others, which already isn't something considered acceptable.

So to me this simply looks like an effective use of existing powers in this situation. I'm not sure how it would slide down a slippery slope. The government decides to keep doing virus screening? I mean, I doubt they would incur the cost, but if they do, good! Maybe as Paul mentioned, we could significantly knock down cold and flu as well. If people are worried about infringing on the rights of people with viruses to live normally, I would ask what about the rights of others not to be infected by them? That besides the fact that if these measures are effective very few people will be getting sick in the first place.
I doubt people are going to want to do this everywhere they go. It's definitely good though to have more testing options.

I've seen posts of using drones to detect 'sick' people... could they create a drone w/ some sort of scanner and microscope that could actually detect covid19 in the air?

Imagine if it could spot it on surfaces, air, etc...might be a bit dystopian, but at least it'd have a further reach than voluntary testing enmasse.

Really interesting read and sounds like it could be a game changer for testing - I know in NY we've been clamoring for increased testing for a while to help us reopen. I've got two questions I'm curious about:

0) Sensitivity/specificity:
Any data yet on what the sensitivity and specificity of this form of test for SARS-COV-2 will be? And, is work in characterizing all of that far enough along that we can expect to see emergency authorization by the FDA and scale up happening sooner rather than later?

1) Reagent supply:
The biggest problem with PCR tests and all seems to have been reagent shortages and supply chains dependent on manufacturers not able to scale. Assuming the test is approved, are there any operational advantages to this approach in terms of securing reagents to overcome that problem?

Thanks for the fascinating read!

Most PC-style drives can't read the second side of "flippy" disks

That's baloney. The whole idea of a 'flippy disk' was to be able to read the second side of a single-sided disk. To make a flippy-disk you merely had to make an index hole in the correct position of the floppy's envelope and a write-enable notch in the correction position of the envelope also.

I made a cardboard template to mark those positions and used a hole-punch of this kind:

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

to make the holes themselves. Note that for the index hole, you had to carefully punch a hole in the envelope only, not the actual magnetic media itself.
"we prefer the term ‘resources"

I so hate the use of the word "resources". so dehumanizing.
The saliva stays inside the tube for that very reason. The test specifically identifies the virus, not the antibodies, again for the reason you identify.

Currently most public buildings are closed, so adding ten minutes is a big improvement relative to that. Also, it probably took them more than ten minutes to drive to work, so I don't think it's completely implausible.

Yep, 4 months. I don't mean they'll actually get that annual salary, just that if they were making less than that annual salary before losing their job then their weekly pay will be more with unemployment + $600. As such, there's no reason to take an unsecured gig-worker job without benefits and with a higher risk of exposure. This is what I means when I say that the millions of new unemployed workers might not be flocking to instacart's 250k hiring binge.

The latest on the COVID-19 R0 is a median of 5.7, up from the previously thought range of 2.2 - 2.7.

https://wwwnc.cdc.gov/eid/article/26/7/20-0282_article

This means herd immunity kicks in at 82% of the population.

Antibody testing appears to be showing infection rates are a lot higher than previously thought as well.

Both of those things together mean that 1) "there's no way to stop it" 2) "it might not be as dangerous as we thought".

But who knows, right? There's a ton of science that needs to be done to find out what's really going on. Large-scale, accurate, randomized testing will hopefully fill out the data picture.

Because the US has an awful medical system where access to care comes through your job, it seems to me that more people will die (from non-virus causes) than from the economic damage than from the virus itself.

I guess we'll know more in a few years.
I can understand risk per time period, but what does "0.5% lifetime mortality risk" mean? Does my lifespan get 0.38 years shorter?
I don't follow your reasoning. Maybe we use a term differently? Here's how I understand them:

- A false positive means that a test shows someone is infected when they are not. For most tests that's somewhere between 0.1% and 2%.

- Lockdown means everyone stays at home. Different from PB's plan, where only people with a recent positive test stay home.

- R0 (technically Re) is the expected number of people each newly infected person spreads it to.

When I say a lockdown has a false positive rate of 100%, it means a lockdown is the same as if you tested everyone but the test always (100%) reported positive, so everyone had to stay home every day.

> people who are antibody-positive have a standardized note confirming recovery

How do you prove recovery if you were never proven sick first?

As an example, I had all the symptoms of Covid in late February, the same severity many people in my age group described, yet was never tested since our health authority dropped the ball and claimed community transmission wasn't a thing back then.

If I tested positive for antibodies, would I get treated like someone newly infected? The only way to prove recovery is to prove you have antibodies and don't have the virus, so we'd essentially have to test every single member of society.
