And the average sugar intake is 65 lbs/year. You don't have to eat that many cookies, just as you don't have to spend that much on a car if you don't want to.

They're including new cars (20-30% value gone in the first year) and large vehicles like SUVs and trucks (Ford F series is the best selling vehicle in America) in those statistics, along with average mileage (13k/y) numbers for average fuel and maintenance costs, which would be much less for a minimal use vehicle.
The author needs to re-run the analysis using only deaths, or deaths plus hospitalizations (if those figures are available). I fear that all the model reveals as currently written is how well states are getting a handle on their testing, and paradoxically showing states with better testing as worse off because of the growing number of cases.
That's nonsense. I've purchased one new car so far. At the time of purchase I needed reliability; no maintenance issues, no shop time fixing anything. Zero. If anything did come up the dealer would have me covered with a good loaner for however long was necessary (which did actually happen.) This was worth many times the value of the vehicle to me. Working wheels, no excuses: it was an important time for me during my career.

I paid off that vehicle in 3 years and I still have it 18 years later. I know everything there is to know about it. I know what to expect, what's been neglected, how it's been treated and what the state of everything is. I've acquired tools necessary to do the bulk of both maintenance and repairs on it, and I know to whom I can turn for the stuff I shouldn't be touching. I have all that and I haven't had to make a car payment in 15 years. I estimate it's good for at least 5 and possibly 10 more years, at which point parts will become difficult to acquire and/or questionable in quality.

The narrow minded 'finance' view of the cost of a new vehicle misses the real value. I imagine the CR model will be the typical bonehead that jumps back on the new car debt treadmill about the time the second set of tires are needed, but we're not all that idiot.
> High prices will redirect scarce resources to those who have the means and desire to pay for them.

That's true. Don't you think it's also true that those who need a good more have a greater desire to pay for that good? I understand that not everyone has the same ability to pay, but we can't crucify the market on the cross of equity. History shows that when you try to allocate goods based on feelings (some random official's idea of "need") and not prices (which reflect true preferences), you create shortages, black markets, and misery. Command economies just don't work.

There are ways of addressing monetary inequality (e.g., a stipend) in an emergency that don't break the fundamental resource allocation function of the market.
The article and my comment are not about rationing. The article is about anti-"price gouging" laws.

> If prices are very high then hospitals may be the only ones who can afford them, versus people on the street.

Outlawing price gauging alone just ensures masks go to people who don’t need them as much as doctors.

The problem is that doesn't seem to reflect the reality of the situation. Why are hospitals still experiencing shortages? What stops manufacturers and sellers from limiting supply to drive up prices? This is why governments are stepping in and forcing medical supplies to go to healthcare. They wouldn't get there otherwise.

Solution: (Company name), the first platform & community for employees starting new jobs. The platform has 3 value components: #1 a community for support/ideas, which also will include matching to an accountability partner (grouped by job similarity and start date), #2 best-in-class downloadable resources like 1:1 meeting templates, 30/60/90 day start plans, OKR templates, problem solving templates (hundreds of docs), #3 private coaching sessions from the executive team.

Pricing: $19/month for community + resources; $39/month for all that + 1:1 coaching sessions from team

[Caveat] I recognize HN is an overly-technical audience, so please consider you in your earlier career or family/friends who are at the beginning of their journey.
Oh I was asking if they( monoids, monads ect) are everywhere like GP claimed then how come monads isn't something that talked about in clojure or python conferences.
Wrote a lengthy post supporting, but decided it’s not worth the overall sentiment here. Will just say this - you are not alone in liking WFH :)

Like most things, it’s a deeply personal choice and making claims about who can and cannot be productive in that environment is just projecting ones own personal biases. Do what works for you!
They are a mafia monopoly in the most classical sense.

For starters answer the question 'why everyone uses Ticketmaster'?

What's the value again?

Because there is no obvious value-creating reason.

Live Nation owns 200 venues, and 300 major artists. With enough control over the value chain, you have to pay their tax, or go out of business as the artists they control - or other artists they can bully - avoid your venues entirely.

Their power is entirely based on anti-competitive practice - they don't actually do anything of real merit.

Plainly 'selling tickets' is not hard.
Is the bar "large profit" or is there more too it?

I think there is more than "large profit" at work here when people talk about disaster profiteers.
Oh I was asking if they( monoids, monads ect) are everywhere like GP claimed then how come monads isn't something that talked about in clojure or python conferences. But its always talked about in scala conferences.
It makes sense to use SRI to control the subresources which get loaded, but there is a clever trick which can be done to ensure that an entire webapp uses a fixed bundle of code.

The trick was discussed on Hacker News some time ago[1], but the basic idea is to use a bookmarklet (or saved local page) which contains a single <script> tag with an integrity hash baked into it. The loaded script (once the hash check passes) then acts as a bootloader for all the other resources that it pulls in, eval'ing them only if their hashes (or perhaps signatures) match a hardcoded list (or public key).

Of course there are some UX issues with this, such as the location bar not containing an actual domain (and reassuring padlock), although it might be possible to fix this depending on how the proposed <portal> tag[2] interacts with SRI. Also, the process of creating the bookmarklet is more awkward than just clicking a link, and it may have to be repeated every time a new version of the webapp is released (or rather, when the new version has been audited by one or more trusted entities).

To all of the disparate opinions in this thread: what about a compromise of 2-3 days of WFH a week?
What's being decried here is reselling essential disaster supplies at a large profit, not just being part of a supply chain. The key words are 'essential disaster supplies' (ie. things that we suddenly have a large inelastic demand for) and 'at a large profit' (ie. taking advantage of an adverse situation to price gouge).

Your local supermarket making 30% on loaves of bread isn't doing either of these things. Healthcare is the closest to fitting the bill, if we're talking about the U.S., and you guys should look into that even without a pandemic as impetus.

Is this redundant, since 0.0.0.0 should include the 192.168.1.0/24 subnet? Not being a smart alec, I'm actually asking: I have an okay-ish understanding of networking stuff but not an expert.
There's a temporal aspect that your comparison misses. That is, after the disaster is done, re-selling supplies like masks, hand sanitizer, etc for a large profit will be just fine. Profits incentivize risk and innovation.
Thank you. The reality is that in 2020 the people buying the ads usually (not always, but more often than not) are expected to account for the return on investment. There’s a little bit of a holier than thou attitude on HN - but if you go deep enough and talk to the people responsible for these budgets, they aren’t stupid and what they are doing is very much scrutinized.

It's fairly difficult to detect a well-made honeypot.

>even just detect latency from their connection being proxied elsewhere

Not if the attacker is legitimately placed far away from you. Also, from my experience these bots have very large timeouts set.
Not to mention, charging hospitals at the front-line of saving us all exorbitant rates (just to stop masks from going to randos on the street who don't need them) is grotesque. You're gouging our first responders just so people who don't need masks don't get them? Are you kidding me? There must be a more effective answer in a pandemic.

This has to be one of the most late-stage capitalist things I've heard all pandemic.
I did a fair bit of hiking all through the park in my youth. We'd go days/weeks without seeing anyone else up there. Most of the Sierras and the west coast/southwest parks are like this. You are very much alone if you choose to be.

There really isn't much else like hanging out with your best friends, fishing for dinner, all alone in the wilderness for days/weeks at a time, hiking and sleeping out under the stars. It's so unique and intoxicating, I have trouble remembering it back home. I transmogrify in the dust of the trail.

I can't wait for this all to be over so I can get back out there like that again.

I started seeing a therapist about a year ago and went through a similar mental switch. I used to think of them as, like "mind doctors" to fix you when something is going wrong. But now I realize therapists are much more like personal trainers for your mind.

I'm not mentally ill or suffering any particular crisis and I still get a ton of my therapy appointments. It's basically an hour with a really smart person deeply trained in psychology who helps me make the most out of my particular brain and personality.
If that's true, it could be an excuse to financialise the money. Let it earn 5% while you don't have to pay it out. Or worse, use it for opex in a big ole ponzi scheme style busines!
Would toilet paper only being affordable to the wealthy be "more important uses"?

That would seem to be the likely end result if it were greatly restricted.

We've already seen that with healthcare in the US. It is expensive, so is it used on more important people?
The difference, generally, is who the gains go to. Societally, we want there to be an incentive and reward to those who will produce the things we need so that they get produced. Giving gains to hoarders who artificially lower supplies and then resell when disasters spike demand does nothing beneficial for society. It's rent seeking at its worst. As an expansion on this, the thing you should _really_ be upset with is people who own land and get massive returns on it. Land's value rarely has anything to do with the owners of the land. Note that I'm speaking of the value of the raw land and not any structure built on top of it. With land ownership, especially in a place like the SFBA, huge economic gains have gone to people who have done nothing than own something and vote down housing.

The broad point of all of this is that society should be structured in a way that rewards act as incentives to people to create more benefit to others. That's the core idea behind an Adam Smith type capitalism.
Yup. Lots of non tech companies (pretty much most) which are still doing tech hiring
That restricts you to 8 bits per color channel, and more importantly, to the RGB color space which is non linear. Comparing colors in RGB color space is nonsense in the first place ('comparing' here is 'judge by human perception'). 'Comparing' colors is just not that easy; in fact, I'd argue that without (much) more definition and clarification, it's impossible to do, because it can mean different things depending on the purpose.
AFAIK, hospitals aren't experiencing a shortage because of lack of money to buy masks. They're experiencing a shortage because there aren't enough masks.

Don't they go hand in hand? If you can't charge as much as you want, that is an obvious incentive to ration.

In part because all the major powers already directed the masks to the hospitals.
It is both immoral and incorrect to measure need based on who has the most liquidity.

It's like you have to constantly keep learning, but nothing you learn really matters in any deep way. It's just new names and APIs for the same stuff, month after month.

Imagine if you were a woodworker making furniture. You make the same furniture every day and love your craft. But every month, someone shows up, takes all your hand tools, and replaces them all with a set that are mostly the same but slightly different and all have completely different names.

Any policy that relies on everyone to just “do the right thing” is not going to be effective in the USA. We’ve seen this for the last month. People are not voluntarily doing the right thing. People think they are being cool and edgy by ignoring. Or they think everything is a media conspiracy. Or they simply value “muh freedum” more than the lives of their loved ones.

These Stay At Home “orders” are pointless because there is no enforcement. They might as well be called Stay At Home suggestions.

How can a confidence interval possibly be calculated without accounting for the number of tests—not just the number of positive tests—and the total population size?

What TFA shows us is the Rt assuming that all cases are known.

The model which knows nothing about testing rate, cannot possibly be used to predict R0 or Rt.

As a simple proof, consider what the model would output I f testing simply stopped. 0 out of 0 tests positive. After several days, the model outputs an Rt=0 with 100% confidence.

If you could account for testing rate, and then attempt to account for missed cases through proxies using hospitalization rates, ILI surveillance data, excess fatality, as well as incubation period, and an asymptomatic rate... maybe then you could draw error bars around an estimate of Rt that would pass the smell test?

If testing was run against 1,000 randomly selected people per geographical area each day, with a positivity rate reported over time, that would provide the perfect basis for making these calculations. The time series of test results that we actually have today require enormous amounts of unpacking before they can be used safely to extrapolate much of anything.
Not totally absurd that animals would have some sort of innate appreciation or sense of beauty -- infants certainly come hard-wired for recognizing symmetry.

Article felt more like "not buy", not "build vs buy".

I just spent an afternoon helping someone to get us to run on-prem. Phone calls! Installs! Vendor management! We didn't even setup TLS b/c gov stuff is complicated! Working with vendor software is so painful!

Except they were originally thinking they'd have to build what we've spent years not only building, but building as GPU / data / etc. specialists, and we've already adopted many best practices for stuff like TLS and navigated other gov systems for them. (It can still be way better, but imagine if you had none of that stuff, and then had to support it!). Even ignore how we're special -- GPUs are magical if you use them right -- just that we have basic stuff built in and with on-going support. That's so key and adds up over the years. We do it for our graph investigation niche, but same deal for almost everything.

As software has matured, and I see more and more orgs dealing with the reality that they're not Google nor Stripe with thousands of the best-paid software engineers, I'm convinced articles should be explaining from the default of "not build".

> less likely that a covid19 death goes unreported

I don't think this is true at all. Many people die at home. Many die without having ever been officially tested. I've read that in some places the death toll is only counted from those who were tested and then died in a hospital.
The article starts by focusing on hoarders, but this is talking past economists focusing on actual producers.

I'd strongly agree that it's economically harmful for people to collect rents without providing any new value, by accident of being in the right place.

Problematic, but murkier, is the case where someone happens to own a mask factory and was previously happy to sell at $0.1, sees that supply is down and demand up, and raises prices to $1. The factory owner is capturing a lot of the surplus, and one could argue this is basically a rent for being in the right business at the right time rather than any sort of economic incentive to act efficiently. But a capitalist would argue this is reaping the rewards of foresight to invest in mask factories, and the chance of this event helped price and incentivize that investment in the first place. Anyway, on the other side of the market, it's not clear that high prices are helping allocate efficiently if places that need supplies most do not necessarily have the most money available to bid high.

The article does get into some arguments about the most interesting case, where actual changes to production and distribution happen because of the crisis and prices' roles in mediating these changes. I like some of what the article says here, but it more argues that the current system is a problem than price-caps are a good solution -- and they have to be combined with other more draconian measures like seizing and redirecting supplies. Maybe a better solution is the government subsidizing all supply purchases massively, and letting prices go wild. (This wouldn't work in isolation either though, we still need some method for mediating between places who gets what.)
If toilet paper was $20/roll, people would think twice before hoarding, and would probably also use less squares overall.
You misunderstand what I'm saying. The more you have to exchange for something, the more you're foregoing other forms of consumption. If toilet paper cost you your entire budget, you wouldn't buy toilet paper at all. You'd buy food instead. In that way, prices redirect your consumption to higher priority things. That's what is meant by "more important."
This is all good an true. But of the two Youtubers I got to talk to at the series finale of MakerFaire in San Mateo, they both whined that advertising rates were going down.

The goal of my discussion was to talk to someone who had "been there, done that" to get an idea of the time investment and the expected returns.

If they want to out themselves here they can. Independently they both have pretty robust tracking software to understand views, view time, clicks from views Etc[1]. Both have systems to measure $/views, and both used extensive "channelizing" to get focused on where the views came from and how their viewer found them. They both observed that if they had been "TV shows", as their ratings and viewer audience expanded their network would get more ad revenue per show, but for them they are consistently getting LESS and less revenue. It puts them on a treadmill of having to produce more videos to get more views to keep their revenue up but that also increases their costs.

It resonated pretty strongly with my experience with AdSense and web pages. We can speculate on why that trend is where it is, but it seems pretty clear that one (or maybe both) things are true; Advertisers don't see as much "value" in advertising on Youtube videos, and the revenue growth curve for at least these two content producers does not seem to match either the slope or the magnitude of the change in revenue that Google reports in its earnings.

[1] I got a good idea of how difficult this path could be when you are your own producer, accountant, and data science company.
Interesting article. In late March I built a simple SEIRD model for a few US states with python. It was very difficult to estimate R0. R0 is essentially Beta/Gamma, where Beta^-1 is is time between contacts and Gamma^-1 is the time until recovery. I think what should be added to this analysis is population density. Each state has a different rate that people come into contact with one another. It would make sense that R0 in NYC is much higher than in Iowa.
