A C172 rents (including fuel) for $155/hr with steam gauges and $175/hr with a glass panel at my local flight school. Way less than half of that is fuel, and no one's getting rich leasing C172s to flight schools.

I think you might see rentals come from $155/hr to $125/hr. I doubt you'd see them go under $100/hr, and I'm not sure that's enough of a difference to drive a material increase in student traffic or affordability.

Believe me, I wish it would. I started flying almost 25 years ago and it was much nicer when the airports were busy and when trade professionals (plumbers and electricians) could afford to fly. Now, I mostly see doctors and tech people at the airport as new student starts and that's not enough to really sustain vibrant airport businesses.
s/we/I

I chose to use "we" both because it fits with the semi-formal tone better, but more importantly because I want to give others a chance to open PRs if they choose to do so, so I was basically future-proofing for a possible scenario where I wasn't the only contributor.
> In an Institutional Review Board approved study performed at a single, tertiary care academic medical center, the medical records of COVID-19 patients were retrospectively reviewed. Subjects were included for whom serum 25-hydroxycholecalcifoerol (25OHD) levels were determined. COVID-19-relevant data were compiled and analyzed. We determined the frequency of VDI among COVID-19 patients to evaluate the likelihood of a VDI-COVID-19 relationship. Results: Twenty COVID-19 patients with serum 25OHD levels were identified; 65.0% required ICU admission.The VDI prevalence in ICU patients was 84.6%, vs. 57.1% in floor patients. Strikingly, 100% of ICU patients less than 75 years old had VDI.

Does this mean they have checked 20 people, 13 (65%) of them were severe and all in the below-75 subset of these 13 people were deficient in vitamin D? Doesn't seem credible to me, I'd prefer some hundreds of people from completely different parts of the country.

By the way, isn't almost everybody deficient in vitamin D anyway? (see doi:10.1101/2020.04.24.20075838)

“Think of the children” is almost always cover for a lack of a rational argument.

In this case, it is distracting from the fact that, compared to smoking, the harm from vaping is so ridiculously tiny as to be deemed “harmless” on that scale.

Smoking kills half of its users (seven million smokers a year dead), and additionally kills OVER A MILLION non-users each and every year from proximity to smokers.

Your hate is misplaced. This is the pinnacle of whataboutism.

Vaping is a huge net benefit to society.
We will never know the answer to that.
I'm not sure Juul in particular contributed all that much to that. Other vaporizer companies had already made great strides on that front by the time Juul came on the scene. It seems like their USP was marketing toward children.
Even in New Zealand the definitions of each level aren't entirely clear. To the point that our Health minister has been caught out multiple times breeching our lockdown conditions.

A few days ago we reduced alert level and many people and businesses have been witnessed breaking the conditions. Some people were always going to do whatever they want, but there are many other that have been confused by rules that change day to day.
As a byobu user, the only difficulties I've had getting it working was when I tried to get it on Android/termux, which doesn't provide Python/etc packages through apt (default termux repos also don't provide gcc). It works fine for me on fedora and other full distros. As far as working well, byobu doesn't work well on windows WSL1, but I think that's more related to the process model being different and the missing (filesystem, init) functionally for status bar applets.
There will always be excuses. At the end of the day it's always capitalized profits, socialized losses.
Juul and similar salt nicotine vapes are only way to get a cigarette like nicotine buzz without having a leaky pipe bomb in your pocket where you have to regularly use ohms law to change your coils.

> Indicator 3 (test capacity) has a very aggressive target. 200 tests a day per 100k? Why must it be this high? (Germany by comparison, opening schools now, is at 80 per 100k). Santa Clara County is already at a 3% positive rate week to date (Korea level during their Feb epidemic)

To actually be able to control the outbreak while people are out and about you need to be able to test lots of people whenever a new case is discovered to see if they actually passed it on to anyone. Each new case will trigger many cases especially if they're showing up sick at the hospital/doctor which means they've potentially been spreading the disease for 2 weeks.
Unfunded pension obligations have seemed to be a ticking time bomb for quite a long time now. Some of the per household pension debt ranges are really quite spectacular[1].

“A vitamin is an organic molecule (or related set of molecules) that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.”

I have no directly relevant credentials whatsoever and don't claim to. (I actually considered saying as such in the writeup but it's already so verbose that I felt it wasn't worth it).

I'm just a dude that likes to read research papers. As an aside, there is totally an archetype of the software engineer that thinks they're equipped to dive into unrelated fields, and I definitely match that trope. I will say in my defense though, that I try to build simple mental models and take them to their logical conclusion, which is a quality that I see in people I admire, and conversely a quality that I find lacking in people that I feel don't have a lot of insight.

Many might disagree but I am a very strong believer that arguments should be evaluated on their merits, rather than credentials. Indeed having credentials makes it that much easier to fall prey to cognitive distortions.

The other issue is that we don't know what concentration of antibodies is required for immunity. We know these things for other diseases, like influenza, chickenpox, etc. We have no point of reference, so we can only test for the presence of antibodies.

I think antibody tests are still likely to be useful, especially in collecting data on the pervasiveness of the disease and getting information to find out what threshold immunity occurs at. The messaging around them is rife for misuse, though.

Everyone is looking for a silver bullet, but all we can do right now is the long, slog of science to get to a place where it's truly safe to try to return to a semblance of normalcy.

> I'm curious what the author things a good resolution for this would be.

Files created by an app (app1) that is being controlled by another app (app2) should inherit the security context of app2, not app1 (or better yet, where privileges differ, apply the lesser of the the two). The fix should be applied where the security characteristics of a file are written. Perhaps that would mean introducing a new primitive that tracks when an app is being controlled by another app -- not sure.

Also, perhaps have special exceptions for files written to places like /Library/Application Support/app1/ -- an app's own working files are unlikely to present privilege escalation opportunities unless app2 is able to exploit a vulnerability in app1.

> Also, who would think controlling a text editor is innocuous?

I can think of several family members who might think "um why?" but not have any idea of the security implications.

I've also been wondering if this is a factor in the high death rates of people who've already been hospitalized, or in their rapid/unexpected deterioration. In a quarantine unit there must be a large amount of the virus all over everything.

If I were to make one request of people, it'd be that they re-read their own writing before posting it--even to Slack or a code-review.

I feel like it's a daily occurrence that I have to read between the lines of what people say and construct my own reply that does the heavy lifting of moving the ball forward by outlining the different possibilities based on what was said.

There's a sense in which lazy writers are offloading thinking onto others. This sort of drive-by writing is pretty annoying IMO. And when there's not someone in the room willing to do the meta-thinking of clarifying, it can lead to misunderstanding or arguments.

It would work if the option was for people to purchase health insurance on healthcare.gov or pay the equivalent amount in extra taxes. Then people wouldn't have any reason not to purchase it. But also, everyone would have to be directed to healthcare.gov without exception to create the appropriate mix of healthy and sick lives for a viable marketplace, which means banning employer involvement in health insurance.
This is it, precisely.

In this same article, the tobacco-powered sources of nicotine use are down this in 2019 to 5.8 for high school students. It's up to 2.3 for middle school users, though.

e-cig (nicotine and some liquids to make it a vape) is up quite a lot; but, it looks like children are not converting from e-cig use to tobacco use, which was a fear that I had when I was earlier considering e-cigs.

My fear was basically that if enough people start using e-cigs and want to "graduate" to tobacco use, then over all tobacco use will increase. That does not seem to be happening in high school students.

It's definitely not good that a quarter of highschoolers are indulging in a highly addictive substance; but, I think there are other means of managing that than making the product illegal or tasteless.

I agree. Languages have different fits for different problem domains. If you're trying to use a language in a domain where it doesn't fit, it's going to be a bad experience, no matter how good the language is.

So then I guess the next question is if it's worse than caffeine or sugar or alcohol; and, if that's enough to require legislation to regulate what people put into their bodies.
That's always going to be the risk until we have a working vaccine though and it's really hard to reopen without childcare in place. Without it a lot of people will have to choose between losing their jobs when their employer reopens or getting adhoc in home childcare.
At any rate, it's a great time to do road construction! I noticed it pick up a bit here in New Hampshire.
That's recently been narrowed down to 98.7% and really only applies to microorganisms, definitely not the definition used for species with sex. Furthermore, the DNA-DNA hybridization technique is considered outdated at this point so one has to take it with a grain of salt. Also, viruses aren't even organisms so I'm not really sure you can even talk about species with them. I have heard the term quasispecies used for them however.

This oversimplifies. The kernel is the same in the jail and the host. But FreeBSD has a Linux syscall emulation layer, and you can definitely install a Linux userspace in a jail and run essentially Linux-but-the-kernel in the jail.

"People get really gung-ho about reusing code and creating shared libraries, but reusing code is actually bad most of the time. You should strive to only depend on things that you can reasonably expect to not change" -- things changing is one of the main reasons you want to share code.
On the plus side, a compound closely related to remdesivir (the drug to which remdesivir is the prodrug) showed great promise in curing this disorder (also known as FIP, Feline Infectious Peritonitis). Gilead stopped the trial because it might have interfered with marketing for human diseases, but if remdesivir goes into large scale production, as now seems likely, cats and their owners will benefit.
The local government is doing what the majority of its citizens want it to do. This is exactly the purpose of having a government.

Every libertarian I know believes governments should provide intervention in these kinds of situations. If you don't, that makes you an anarchist (or whatever).
Why was this flagged?

I don’t even necessarily agree with the author’s arguments and conclusion, and honestly I have no clue what to think with all the information I hear that is constantly changing from the various tribes.
But when something gets flagged simply because he advocates for ending the lockdown, I go from thinking the lockdown is probably necessary and trust the decision is made for reasons I don’t understand, to thinking like the paranoid conspiracy theorist that this is just a totalitarian power grab, and figure the need to suppress dissent means that it is more likely his position is the right one. If the ideas he is presenting are so stupid then people can decide that for themselves and don’t need some moral busybody protecting us from thinking for ourselves by flagging anything that states the opposite of what their tribe thinks is true.
That's true, I think a lot more can be done for the WFH perspective. If companies offered all employees a good home setup, good desk, chair, screen, keyboard, mouse, headphones, good mic, good webcam, a good whiteboarding solution as well like maybe an iPad + pencil. And there was an app allowing remote share, remote control, remote whiteboard, and subsidize cost of a good internet. I feel I'd be even more productive at home with all that in place.
It can saturate 1Gbps with the TUN driver, sure. 10Gb is harder with TUN. Linux's native driver is lower overhead, although as siblings point out, there is work in progress on a native FreeBSD kernel driver.
Is taking up vaping bad for youth that are under the age of 18? Is taking up vaping bad for adults over the age of 18? And I do mean, when they otherwise were not smokers? If so, has Juul actively tried to market their products to non-smokers in any range? Have they actively tried to inform the public about the potential harms of starting to vape when you are otherwise a non-smoker?

There is no doubt that Juul is safer than a pack of cigarettes. But Juul can't make it as a start up selling to only smokers who want to reduce their risk of death, as has been seen by their sales numbers. They are actively marketing to groups of people who are in zero current harm from first hand nicotine. And nicotine does harm those people. Here's a peer reviewed article just to make the point.

It could be argued that governance is better in other countries at least in part because there are more parties. After all, it enables alternative voices to be represented better, and it reduces the power of centralised party structures.

On the other hand, too many parties becomes unwieldy, and I'd argue that 10 is already going to be too many in practice.

Historical experience in the early 20th century led many countries to develop minimum bars, e.g. parties with fewer than 5% of the vote not getting any seats in parliament.
I have never seen this scale of sacrifice for this scale of Quality Adjusted Life Years. Just the impact on the kids missing school will be worse than the impact from the virus.

Proportionality frequently seems to escape journalists, why be satisfied with reports being confined to the qualitative and non-quantified realm? Give us some background please. In this molecular diagnostics domain what are typical figures for sensitivity and specificity? FDA lays down requirements for such things right? Anyone know off-hand what percentages are required for a diagnostic testing product to be released? For these tests in question how far off from those marks are we exactly?
Among smokers juul is about the only vape that size that delivers a cigarette like hit. Those little blu vapes? Poor draw and not strong enough to make a smoker switch without vaping a ton or supplementing with a patch. If you are worried about vapes with too much nicotine, look at the people blowing plumes of steam from what looks like a pipe bomb. A big hit like that could make you fall to the ground if you didn't have a tolerance, encountered that first hand.
Based on the false positive and false negative rates of some of the tests out there, he's not wrong.

There were several tests rushed out the door. It's hard to make the right call when you can't trust the results of your test.

Interesting. The Zinc supplement that I started taking a couple times of week due to COVID-19 exceeds all upper limits listed on Wikipedia when taken at the recommended daily dose (50 mg).

https://en.wikipedia.org/wiki/Zinc#Dietary_recommendations

> In the case of zinc the adult UL is 40 mg/day (lower for children).

> The EFSA reviewed the same safety question and set its UL at 25 mg/day, which is much lower than the U.S. value.
This statement was the source of widespread criticism and I in fact criticized it myself in the writeup.

I considered going for a deeper debunking but held off for the initial draft. I might circle back if people feel it's valuable. Let me take a quick stab though:

When we talk about immunity we need to realize the term is used imprecisely by laypeople (btw I'm totally a layman if it's not already clear).

I think of it simplistically as two components:

(1) The presence of actively circulating antibodies in the bloodstream. This is what the (oddly controversial) serology studies are measuring. It is thought that having a significant quantity of these antibodies prevents infection - i.e., what most people envision when they talk about immunity.

(2) Even after the antibodies have faded, there are still Memory B Cells, which lay dormant up to decades, waiting for exposure to the characteristic antigen (in this case, an antigen telling them that they have encountered SARS-CoV-2), at which point they resume and rapidly scale up production of antibodies.

The thinking here is that reinfection is likely possible after a sufficient length of time - whether that's a couple months or a couple years isn't yet known - but when you do get infected, your immune system will respond sooner, more strongly, and thus you will achieve a far lower peak viral load meaning a less serious infection with reduced transmisibility.

This is a robust mechanism that we see across tons of disease, including common cold coronaviruses. In my completely uncredentialed opinion, this effect is so common and well-supported that we should essentially assume it happens until we really have proof that it doesn't. I know that might sound backwards, but it really is such an enduring mechanism.

--

Here's another argument you might prefer. We know that at least hundreds of thousands of people have successfully recovered from COVID-19. Loosely, we can divide the immune system into the "non-specific" and the "adaptive" subsystems. Given that we have seen extensive recovery from this illness and that those who have recovered have detectable levels of antibodies, and furthermore that there is a case of a women who could not manufacture antibodies due to a rare auto-immune disorder who failed to recover, it stands to reason that the same mechanism that provides medium-term immunity is the mechanism responsible for recovery.

That is to say, that it's very farfetched to think that people are recovering purely from non-specific immune responses and that the detectable presence of circulating antibodies is just a red herring. But I suppose you could try arguing that if you wished.
> The most extreme example is a secret that if I shared with you, I'd die painfully. You can't threaten me with death or torture because that's what's going to happen to me if I share it with you.

I say this regretfully because I really like the slogan "technology that allows you to say no to things is great", and, of course, it's not what you meant; but, taken to its extreme, the combination of this paragraph with the logic from your first paragraph:

> This is a fantastic feature … technology that allows you to say no to things is great.

means that an imaginary Zoom feature by which it would kill you painfully if you leaked sensitive data would be fantastic.
True, but that still doesn't preserve root.
