And the trillions of loss in economy could have been much lower if everyone wear a mask ( Surgical or not ) and kept business opening. It will also greatly flatten the curve in public health services, while buying time to find a vaccine or improve health services capacity.

There is no reason why Mask's supply problem could not be solved when you are looking at a comparatively speaking trillion of dollars package not to save the economy, but barely holding it up so it doesn't fall.

I am still baffled at the insistence that mask are useless, surgical or not. When there are ample of evidence to suggest it is the best tool to help and stop virus from spreading.

They keep talking about how masks does help and show Taiwan can produce a lot and then show pictures from the US of people with respirators - not masks.

If you don't understand the difference between a mask and a respirator I'm not surprised you misunderstand the surgeon general. Masks is to keep spit and the likes away from others (no it doesn't filter viruses), respirators are for filtering viruses, etc. in both directions (unless it has a valve, then it only filters air in, not out).

Unless you use sterilisation for your masks and respirators they need to be used only for short amount of time and you need to wear gloves when you take it off. If you just use it as most people outside of healthcare does all you are doing is wearing a Corona bomb on your face. Keeping alittle distance is much better and won't cause respirator shortage.
Coronavirus Stimulus Payments: When Will They Be Sent and Who Is Eligible?
> A "shit job" is by definition one that creates little value because value is defined as what is lost when someone exits the picture.

There are two people involved in the transaction: the worker and the employer. The employer will value the work at a value greater than the wage, otherwise they would be more profitable just by firing the worker. Similarly the worker will value the wage more than the job, because otherwise they would quit.

When most people talk about the "value" of a job, they tend to not use either local definition, but from a more global definition of "how bad off would society be if nobody did this job" and that more closely aligns with the employer's value than the worker's (e.g. for services jobs the employer makes money on the spread between what customers will pay and what workers will work for, so clearly customers value the job at some margin above the wage, and we can use customers as a proxy for "society")

Without UBI, the wage is what lets the worker not end up homeless and starving (or begging), so someone with no better job prospects will value the wage very highly. Once you add UBI into the mixture though, maybe it's "move into a larger apartment" or "eat out somewhere nice once in a while" and suddenly they value the wage much less.

Of course they did—the same way they bought things at the local mom & pop stores before Walmart came in, undercut them, and drove them all out of business.

Companies like Amazon and Walmart massively distort the market, and do so quite deliberately. It's hopelessly naïve to think that if they vanished tomorrow, everyone would be able to just shrug and switch their purchasing to a drop-in replacement.

That's only possible in, as someone else described it, the "spherical cow in a vacuum" type of hypothetical free market. We live in the real world, where an arbitrary number of fully equivalent businesses can't actually continue to compete perfectly for everyone's money.

Ask HN: Advice for Raising from Family Offices?
Hi! We're working on an esports brand that we previously raised pre-seed for by doing traditional VC.

However, for our seed round, we've received some advice to look into raising from family offices and UHNW individuals. This is completely out of my expertise. Are there any strategies/guidelines/suggestions for doing so?

Thanks!
Another thread on HN [22705511] points to a press release from
a company making a product that uses UVc light to disinfect
breathing air. What kind of UVc light is not disclosed, but a
search of the website hints at their product using 254 nm light.

Making clean air sounds good, but we should ask: Does it also
make ozone? I thought this might be worth checking.

Ozone is pretty toxic even in low concentrations. The recommended
and permissible exposure limit is 0.1 ppm [1] as set by both OSHA
(Occupational Safety and Health Act) and the NIOSH (United States
National Institute for Occupational Safety and Health).

In looking for information about ozone generation by UVc
I found the explanation on the Oxidation Technologies website.
They wrote a clear explanation for non experts that answers
our question. It appears 254 nm light dissociates ozone to
pure oxygen. That would be a statistical result rather than
absolute. That is want I want to share here without interfering
with the HN discussion on disinfection.

Honestly, a grotesque carbon tax of 300% on a barrel of oil would only put prices back to where they were before the Russia/Saudi dump.

You’ll find that people will adapt quite quickly as the price ramps up (we can smear over a year if we need to). Carpooling, switching to electric, or just getting a closer job will all suddenly seem very feasible when the numbers are concrete.
Any thoughts on how it can be improved, any part of the message that is unclear etc is appreciated.

Mr. Stoll, do you agree?
Define "removed".

There are three possibilities that could be considered "removed":

1) the post fell off the 'new' posts page. This is normal, the 'new' posts page is simply a reverse time ordered list of posts. So a sufficient number of new posts arriving quickly will push any given post off the first page of new items onto subsequent pages of the new list.

2) the post made it to the HN front page, but then disappeared from the HN front page. Posts make it onto the HN front page by receiving up votes from users, and the algorithm has some time based considerations that it uses to decide if a post qualifies to be one of the posts listed on the first section of the front page. The speed with which upvotes arrive, and how many upvotes in total, seem to have a bearing on a post being on the main page. So if this is the case, it is possible it got enough upvotes rapidly enough to make it to the main page, but did not receive enough additional upvotes once there to remain eligible to be on the front page. This is also normal, and is just how HN's front page algorithm works.

3) the third possibility is the post was flagged. In this case, a sufficient number of users pressed the "flag" link on the post to cause the software to mark it "flagged" and remove it from view. Note that you need a certain level of karma points before you gain the ability to flag a post. If the post was flagged, however, you would see that fact in the 'submissions' section under your account name. The post title will begin with "[flagged]" if this is what occurred. This is also normal, however the guidelines indicate that flagging should generally be used for spam or off-topic posts (https://news.ycombinator.com/newsguidelines.html) so if the post was flagged, you might consider comparing the post's contents with the guidelines to see if it might have been considered off-topic or spam by some.

Yup, I meant primarily small groups. Coarse-level bioweapons have bad payoff for governments - they're as likely to harm the attacker as the target. A targeted weapon, hurting only a specific group of people, would be more useful for a government, but it's still risky business - pathogens tend to mutate rather fast. I'm more worried about the crazy people that have a grudge and/or a point to make, and no regard for their own safety.

You're mistakenly assuming that our only use for oil is energy production.

Oil has many uses besides as an energy source. Even in transportation, oil is still useful as an energy transfer system even if it isn't an energy source.

Net-loss energy systems are very useful. Fuel cells and batteries fall into this category. The latter has already begun to function as a replacement good for oil in the automotive industry.

Unfunded liabilities are future liabilities projected out 75 years.

Much of it will never come to pass. For example, the part that constitutes Social Security can and almost certainly will be mostly wiped away in an instant by increasing the retirement age by a few years and increasing the payroll tax cut-off.

And I'll bet you a beer that the $132 trillion figure is calculated using year-of-expenditure, not constant dollars, which means the predictions are literally inflated.

I tried to confirm but couldn't find the original sources and methodology. AFAIU year-of-expenditure is typical and best practice for long-term budgeting, but laypeople invariably compare it to constant dollar costs, which makes such figures seem larger than they really are, particularly when they include up to 75 years of monetary inflation. For example, California High-speed Rail is always quoted in year-of-expenditure. Much of the difference in the original ~$30 billion figure to the current seemingly insane ~$100 billion figure is because the construction timeline was stretched out by another decade or more since the original proposal. The longer construction takes, the more inflation figures into projections, the greater the figures, the less public support there is, the more construction is delayed by scared politicians, etc. It's a horrible cycle.

I'm worried that bioweapons at present levels of technology/understanding of science are just too risky for sane people to deploy. Even if a vaccine was paired with a pathogen, the risk of mutation making the vaccine irrelevant is too high.

> Is an extra 2 million US deaths in 2 months within your experience?!?

No, but extremely well grounded and understood epidemiological models say that that is the likely result. I accept that things far outside my experience can happen, especially when there are strong scientific grounds for believing so. You don't want to damage the economy with lockdowns, so you're dismissing basic epidemiology. You earlier accused me of intellectual dishonesty, but your basic argumentation here is driven by what you want (not to damage the economy), rather than what the facts indicate (that an unchecked COVID-19 epidemic will eventually infect about 60% of the population and kill about 1% of those infected).

The intellectually honest argument for you to make would be this: "If the choice is between locking down the country for a month and damaging the economy, or letting the epidemic run its course and kill 2 million Americans, then letting the epidemic run its course is preferable." But you're not making that argument openly, and are instead trying to dismiss epidemiology.

> You say that as though it's "just some boomer's 401k"

I haven't said anything about "boomers," and in fact, I find it stupid when young people online dismiss "boomers." Baby boomers are going to be hit especially hard by this epidemic if it goes unchecked, and I think accepting damage to the economy is far preferable to letting the healthcare system collapse and large numbers of elderly people die.

Trick is, nobody is buying ads at the moment because nobody is spending on advertised products. So demand is way down, which means the value of the ads is also way down.

If the numbers work out the right way, they might even be turning a profit by giving ads away.

Oh, how I wish. Dart is no C/C++ with preprocessor insanity, but it has quite a rich grammar.

> The challenge is when the program is _not_ well-formed, i.e. has errors

Being able to format erroneous code has come up as a feature request a number of times. It would be useful because then you can format even in the middle entering code into your IDE. We do have a very robust parser that can handle incorrect, incomplete code and give you a partial AST.

One of the reasons I've hesitated so far is that testing that in any sort of rigorous seems really difficult to me. Not to mention even defining what "correct" formatting is with code like that.

> refers to to code elsewhere, so you can't even decide if it's well-formed or not.

Thankfully most languages are context free, so that's rarely a problem outside of C/C++. :)

Dart does have a couple of semi-contextual syntax corners that could potentially affect formatting. An expression like:

foo.bar();

Could potentially be:

* Call the method "bar" on the local variable "foo".

* Call the top-level function "bar" imported with prefix "foo".

* Call the named constructor "bar" on the class "foo".

Because dartfmt does not do symbol or import resolution (for many reasons), it can't distinguish those cases. In practice, all that means is that we don't have th eability to have different formatting rules for those different cases and they are all formatted uniformly. So far, that seems to be an acceptable limitation (though it would be nice if we could treat import prefixes as stickier).
In a similar vein, a friend of mine released a really simple finger labyrinth app awhile back:
