It appears to depend a great deal on the all of those factors and more, for example viruses become inactive (unable to infect) over time outside a suitable host environment (depends on the exact kind of virus, surface, and environment.)

There was a recent twitter thread by Palli Thordarson that covers some of the chemistry. The most readable version is: https://www.targetliberty.com/2020/03/everything-you-should-... (HN discussions: [0], [1])

I recommend reading the whole thing, some highlights relevant to your question:

"Most viruses, including the coronavirus, are between 50-200 nanometers – so they are truly nanoparticles. Nanoparticles have complex interactions with surfaces they are on. Same with viruses. Skin, steel, timber, fabric, paint and porcelain are very different surfaces."

"Now it is time to introduce a powerful supramolecular chemistry concept that effectively says: similar molecules appear to interact more strongly with each other than dissimilar ones. Wood, fabric and not to mention skin interact fairly strongly with viruses. Contrast this with steel, porcelain and at least some plastics, e.g. teflon. The surface structure also matter – the flatter the surface the less the virus will “stick” to the surface. Rougher surfaces can actually pull the virus apart."

"So why are surfaces different? The virus is held together by a combination of hydrogen bonds (like those in water) and what we call hydrophilic or “fat-like” interactions. The surface of fibres or wood for instance can form a lot of hydrogen bonds with the virus. In contrast steel, porcelain or teflon do not form a lot of hydrogen bond with the virus. So the virus is not strongly bound to these surfaces. The virus is quite stable on these surface whereas it doesn’t stay active for as long on say fabric or wood."

"The skin is an ideal surface for a virus! It is “organic” and the proteins and fatty acids in the dead cells on the surface interact with the virus through both hydrogen bonds and the “fat-like” hydrophilic interactions. So when you touch say a steel surface with a virus particle on it, it will stick to your skin and hence get transferred onto your hands. But you are not (yet) infected. If you touch your face though, the virus can get transferred from your hands and on to your face."

I don't think it's a lot to ask that I'm informed how much I'm going to be charged before I pay for something, which is the process for every sale I make currently works.

What if the item is marked as on sale but the database hasn't been updated so I don't get the sale price?

What if the price on the item is correct but someone fat fingered the price in the database?

What if a different customer moved an item from one shelf to another so the price on the shelf is for a different product?

What if I want to know the total with tax?

What if a camera sees me pick up a $500 item to look at but doesn't see me put it back on the shelf?

I don't want to go home, wait an hour+, see I've been mischarged, and then have to spend a week waiting for a refund to process.
What is the end game with this strategy? If you sell the puts today to capture the profits, do you also sell your equities? If you don't sell your equities isn't there a chance the slide further? If you hold the puts to maturity why buy them at all?
Huh, this was a ton of speculation in 3 paragraphs. Could you expand on what are the huge positions that are looking to sell? Are there any examples of overpriced equities?

I think your second paragraph makes sense given some large cap companies holding so much cash on hand due to inability to find anything useful to invest in (and stock buybacks)./
Hmm, the problem with analogies is that they are analogies. I don't think NYSE or ICE has the same kind of impact on the market as a stamp collectoe. Hell, NYSE is almost literally the market. Thus any rules enforced by it are, for all practical purposes, market rules. They may agree with themselves that saving the market is the right thing to do, but guiding it does not make it free. It makes it not free.
If you’re the first to panic, you get out with most of your money. Panicking first is kind of their job.

This advice is both common and crazy. Each individual does not live the average life. Being able to recognize once-in-a-lifetime events, and act on them, is a rational strategy, even if it seems like it is not the optimal strategy for the perfectly spherical portfolio belonging to a person with infinite lifetime.

* Does twitter sell ads?

* Do ads work better with high-engagement content?

* What does creating a platform optimized for high-engagement content look like?

Therein we have the problem of twitter.

Perhaps Im reaching here but conceptual defense of anything left-leaning is always emotional appeal and not weighing the totality of incentives.

Stated more simply: The left has low-resolution arguments and claims always degrade to shame-attempts -- misogynist, xenophobe, nazi. Memes easily 'parroted'.

So in order for the sh!t-storm to continue, the lefties need someone who'll grant them handicaps. Because the most informed among them is some short-male syndrome with a manbun.

And the left-leaning, socially-docile males employed in tech are happy to parrot their dogma.

Protect the stupid, so that the rage-machine can perpetuate ad-sales.

All the while the average male still seeks something to defend in their life, so they adopt the most accessible social-narritive.

PROTEC THE WAMEN!
Don’t forget “loss prevention officers” (i.e. security.) In the bad parts of my city, and especially at night, convenience store staffing is 50% security (= one clerk at the counter; one guard at the door.) And that staffing, unlike the clerks, can’t be done on minimum wage.

K Readme: A spreadsheet in a couple lines of K
With zero or negative growth looming both in China and Germany in the coming quarter, it is a safe assumption that this market has much lower to go to reflect those new realities.
On the one hand we argue the Internet should be global and not get Balkanized and on the other hand we arbitrarily select certain countries to place lesser or higher trust in. Someone in China could legitimately have a similar low level of trust for US root certs and he/she would not be far wrong given that NSLs can gag companies into complying with arbitrary dictums that no one ever knows about.

Are you referring to a health share program? In order to spend your health stipend tax-free, you must be enrolled in a plan that has Minimum Essential Coverage. Paired with an MEC plan, you could pay for medical expenses tax-free as part of a health share.

hopefully this will make the actual costs of private health insurance more clear. right now right-wing media emphasizes the cost of public health insurance, which sort of works because the cost of private health insurance is hidden in the company's balance sheets instead of individuals'.
Would you want to get into the market if it wasn't a system built around increasing market value?
IIUC, there’s no denying coverage for any reason during open enrollment. Are you referring to applying to get insurance mid year? If so you’re likely out of luck even if you’re healthy as there’s no mandate to force selling it to you.
I don't think getting rid of the people who know the system best will help anything. Some new guy who comes in with no clue of what happened or any of the codebase is not going to do a better job. It's just going to reduce long term productivity and increase risk.
>I have a pessimistic view on Apple and Macs based on how this product line has been neglected for years

Which is unfortunately true. They still have this idea that every update needs to be "meaningful". That would have been true if the Mac were still targeting consumers. But most consumers have moved on to Tablet and Phones. The Mac market is only left with "Prosumers" and Professionals.

It took them 6 years for a Mac Pro replacement and 3 years to admit their Keyboard mistake. And the new magic keyboard may be more reliable, but honestly its shallow typing feels still sucks.

The rate of AirPod, Apple Watch, Services's growth would mean Apple no longer give a damn about the Mac.

While it was all very bitter, they will continue to milk the market, after all there are over 20M iOS developers, that is nearly 20% of Active Mac users. I am not sure if that number is iOS developer account or individual numbers, but it is clear if you want the 1.2B iOS Devices Market you will have to develop on the Mac. And you will have to continue to pay the premium for it.

It makes sense to also post your role if you're posting your meeting hours here.

Because if you're a VP or senior director then yeah, your life is probably meetings and that's normal. If you're an engineering team lead spending 16 hours a week in meetings, well maybe not so much.

Without that info your post doesn't really tell us much, other than some people have more meetings than others :)
"Thinking I had the symptoms" ... this is why the shortage of test kits is so critical - you can't (easily) dismiss those with similar symptoms in a way that leaves them feeling as though you cared for them. You'll get some small percentage of hypochondriacs who show up repeatedly but most people will hunker down and watch their symptoms disappear.

I ended up with bronchitis after a trip to Cuba in January, so how will I even know if I end up with a lung illness related to COVID-19? Let's get those tests into mass production.

P.S. I saw the link to the Wired article which quotes Trump as saying the tests are all perfect (and available). I wish/hope/pray that this is true.

Smart devices are eating the market for accessibly-priced watches
You guys keep saying you hate saying this and feel bad saying this, yet you've each posted repeatedly and your comments already make up a third of the thread as I write this. That's because reflexive comments on divisive topics (like healthcare) are the easiest to write and tend to fill up the threads early on.

Let's not have yet another predictable flamewar about U.S. healthcare. It will just turn into the same flamewar as the other flamewars, which is something we try in general to avoid on this site. Meanwhile there's something specific to discuss about this startup's particular model, regardless of where one stands on the brokenness of the overall system.

You'd use chain pulleys. I work for a company making (among other things) rudder steering machines, and they are typically engineered to never fail.

As a first-order approximation, that holds true. (In the event of a black-out, there are redundant power supplies and mechanical fallback controls (think big, geared control wheel) - or also hand-crank pumps and hydraulic valves.

It is far more common for the rudder to fall off than for the steering machine to fail catastrophically.
Market makers are buying - their job is to always buy or sell stock from everybody. They (generally computers, but humans traditionally) will always buy your stocks, or sell you stocks. Their algorithm is simple: buy for $.10 (or some other tiny number) less than you sell - if the amount of stock owned is too low raise the price, if the amount is too much lower the price. They pretty much always make money in the long run.

There's logic to this... Most exchanges have most of their funds offline, and only a small portion on their servers (to reduce losses in case of a hack).

When volumes go up, the servers run out of money, and everything grinds to a halt till humans intervene.

The humans typically want to do a lot of checks they aren't being tricked into refilling the online wallet too. Those checks are usually manual and take time.
FYI, when an employer signs up with Savvy this qualifies as a special enrollment period for all employees. This allows them to enroll in health insurance mid-year.

EDIT: The scene I referenced is 13 minutes and 43 seconds in. Also, I had forgotten that there were two shooters in the beginning. I only remembered 'the mailman'.
I think you are misrepresting my argument and attempt to dismiss it in an odd way.

I am arguing that rules set up by the market do not automagically enforce free market. I am arguing that rules explicitly do the opposite by introducing guard rails, which DO restrict movement in that free market.

Do you honestly believe that rules derive its effects from who sets them up?
Market was all screwed up because the interest rate was so low. If bonds pay nothing, where else do you put your money?
"A straw man (or strawman) is a form of argument and an informal fallacy based on giving the impression of refuting an opponent's argument, while actually refuting an argument that was not presented by that opponent."

Saying "but you may as well" gives the impression that you refuted the point the quote was making, but in reality you were refuting a point that, by your own admission, the quote was not making. That is a strawman.

Reading between the lines of a commercial is fine, and encouraged. Dismissing the point of the commercial entirely because of a semi-related tangent is not.

If you meant it differently (perhaps not to dismiss the quote's "argument" but instead to just bring up the privacy implications separately) that's great and I'll take your word for it (and even agree with it), I just found your original quote to be saying something different.

edit: I see that you are not the original poster of the comment. This comment was meant for that person, not you. Apologies.
What? He used the platform to solicit feedback of the platform. How is that not a good thing?
You are wrong about that. See T5, T6, and H10 halts.
The reasons for that, both in private institutions like stock exchanges, and in terms of regulation, have mostly to do with how hideously volatile 'freer' markets tend to be, and the frequent, devastating effects banking crises, panics, etc used to have.
The iMac Pro was released in December 2017. No real comment on the rest of your thesis, just wanted to correct that little bit.

It turns out nobody really trusts the "free market" :)
Exactly. When the virus is at its worst is when the market will start to bounce back because recovery will be priced in. The markets are all about the value of the future. That’s why it’s all kind of a joke to me. Its based on hopes and dreams(or fears and nightmares) instead of how a company is actually doing.

> What? That's how you minimize risk because there's a good chance the markets will continue to slide.

You don't minimize risk by reacting to daily market fluctuations. You minimize risk by choosing an asset allocation that allows you to ignore those fluctuations.
It probably doesn't make sense for an individual actor to stop trading when all the assets it holds are tanking. Everyone's selling to cut their short-term losses. Crashes aren't always feedback loops.
Yes some part of the world still use this term, like some still use body parts to measure lengths, but we should not continue to be racist because of them. You can read the Wikipedia article, there is no good point of using race in science today.
Comparison of Different SQL Implementations
[edit for readability]

Complexity in every sense, at every stage of the design, testing, fabrication, and delivery.

From discerning appropriate tactics for the coming century (which are used to produce design requirements that equipment is designed against) to writing the user's and maintainer's manuals, to the number of people required to get a particular sub-system into production, and so on.

The bottom line is that a modern tank requires more people, more knowledge, more complex (number of parts, functionality, materials selection, fabrication, testing, etc.) and interconnected sub-systems, more complex manufacturing techniques, tighter tolerances (sometimes) (which lead to more complex methods of measure), more exacting specifications, etc., than a modern consumer vehicle.

A standard automobile may have 20 to 50 microcontrollers that talk to each other on one CAN bus. A modern tank has at least 3 independent communication networks, an electrically isolated diagnostics system, distinct optics systems for the commander and pilot and gunner, a fire control sub-system, and so on. Each of these subsystems is immensely complex, designed and manufactured to exacting specifications for durability and maintainability.

The specifications for each are so exact, that any subsystem can be torn out and another designed to the same spec can be swapped in. This is no trivial feat. This isn't like a new set of rims onto your car. It isn't even akin to piggy-backing or changing out the ECU in your car. It is at a whole different level, because each sub-system has to integrate with at least two other sub-systems (power and communications). This is like being able to tear out the autopilot portion of your Tesla and swap in some other company's autopilot, while keeping the rest of the systems intact.
It's an embarassing problem to have a system with "accuracy to high to measure"!
