Yes, for some reason people complaining about the supply-demand economics of price gouging laws seem to think Clorox, Charmin, Kleenex, etc are the ones jacking up the prices of supplies...

Manufacturers producing enough quantities to sell is not the issue. The assholes that swoop in and buy out all the stock in a store temporarily to quickly turn around and sell the items for much more are doing the gouging. It's like going to the gas station right after a refill with a big-rig tanker during a time of high demand, filling up all the gas from the station, and then sitting next to the now-empty gas station all day and charging people 500% more for gas.

That is why stores are now implementing quantity limits for certain supplies, so people don't just hoard them for profit and to deny everyone else access to buying the supplies.

Organizations that really need it probably aren't going to be buying from a sketchy Amazon marketplace seller.
This recipe is a fantasy.

And it is not what has happened in any population except maybe a few groups of medical workers who were treating patients in outbreak zones.

But it's a fantasy because of how slow the controlled spread would have to be.

Some of the best medical systems in the world have been pushed into chaos with less than 1/1000th of the population infected. This level has increased the mortality rate by two to ten fold, depending on age group (with younger groups seeing a much greater increase).

If each 1/1000th of the population takes weeks to be infected and recover, then this plan will take at least a decade to reach the levels of exposure required for herd immunity. And by that point, the virus will likely have mutated into something that those previously infected can catch, destroying the benefit of the plan.

The only solution right now is total quarantine. Even maintaining infection rates of 1/1000th of the population is going to require that.
Google the "Bullwhip Effect" to get an idea of how disruptive this bahiour can be, for everyone. And if individual behaviour has negative impacts on others, yes it's selfish.

Supply will be kept open, quarantine or not. Italy and China are the best examples, groccery stoes and pharmacies remained open. It is much harder to do that, so, if everybody goes panic shopping before. So please, don't do that.

I had actually used EMI shielded wires - but, I think I must have had a faulty connection from shield to ground. Practically speaking, EMI shielding is hard to get right if you're not a pro. I only recently got an Oscilloscope and was able to measure what the EMI noise actually looks like on a wire. That helped a lot in getting rid of it, too. VFDs are pretty awful - the one in my machine nominally outputs 8amp,220v, 500hz power, containing that is a matter of extreme care. My previous CNC (now sold) really just didn't make any attempt and just counted on physical separation of wires and software filtering of signals.
Except no one normally says that. Also inactivate connotates it can be reactivated, destroy would probably be the better word for something not considered alive at least for lay people. I know some people worry inactive viruses in vaccines can reactivate and infect you.

Then again most people will just say kill since the same agents that kill bacteria and other fully agreed upon microscopic life forms tend to work similarly on viruses.

Launching a product in the midst of Covid19 pandemic – what are your thoughts?
I've seen some concerns in the founder community about whether to hold off on launching or expanding the launch of their products, given the COVID19 pandemic. My thinking is that it depends on what people are building, what industry they are in and who their customers are. If you are developing any tool related to remote working - I'd think this is possibly a good time to launch given a lot of people are working from home now and are likely to be open to new and improved remote working tools. If you are developing anything relatively new which requires you to launch in parts, get feedback, iterate etc. (like we are) - I don't see any harm in launching or expanding the launch. In our case (for example), we are still getting the same customer engagement as we were before the pandemic.

May I ask your age? You sound a bit young. The things you talk about are well-within the purview of the government.

If this were happening in the 1980s, I think that we would have kept our calm better. I was a child then, and my grandparents were in their 50s/60s and had seen the Great Depression and World War II. My parents' generation (the boomers) were full of well-trained doctors and nurses. There was a general level of competence and a willingness to give of oneself then that I believe was higher than today, even though we have more access to information now.

What I'm saying is that we need central solutions. Scientists and medical experts should be directing this. Like they used to, before several decades of being undermined by political and religious dogma.

> Even if you can, why would you?

It's always a trade-off. You can take less equipment with you but be less effective when you get to wherever you're going, or you can take more equipment but have a harder time getting there.

You may simply be doing that something that requires 20 kg + of equipment when you get there, so not much much of a choice.

Weapon systems, communication systems, climbing gear, oxygen, tools, whatever.
Ok but it's not always possible to resupply like that, hence why someone may be carrying more.

For the most part, CVS isn't producing it, they're reselling it. I agree it doesn't matter which reseller is gouging, but it does matter to me whether I'm paying a markup to someone who was clever enough to hoard important goods (and thereby incentivizing hoarding) or whether I'm paying for increased cost of production (and thereby incentivizing production).

Markets are a way of managing information. That's why things like "the stock market went up" or "the stock market went down" matter: it communicates what people believe about whether things are underpriced or overpriced. In turn, those beliefs are only worth paying attention to if participants have some reasonable information about the things they're buying and selling. While my individual purchase of a $50 bottle of hand sanitizer is a small drop in a bucket of information, it is conveying information, and everyone else paying for it absolutely does influence the market. When we communicate that we're willing to pay $50 for a bottle of hand sanitizer even if the cost of production has not gone up, it tells resellers that they should start hoarding. A clever reseller will stop selling their reserves entirely and wait for discovered prices to max out. That does matter quite a bit to me as a buyer!
> A disease center would study known diseases.

Disease centers often study known _pathogens_ in lab conditions/through methods that absolutely can lead to said pathogens mutating into a previously unknown strain.

You're overly focusing on _bioweapon_ as though all pathogens that developed via human influence were due to maliciousness.

In a country of 300 million people, a few semi trucks worth of hoarding isn't doing much of anything to availability of any particular product.

It's the just-in-time nature of distribution. Demand doubles from "normal" and all of the sudden nothing is sitting on the shelf.
Have you subtracted all the losses on the products that didn't sell?

When I sold on Amazon, every so often I'd be able to 10X my money on a product, but it was rare and balanced out by the many more times that I would lose money on a product or have to write off completely because it didn't sell.

You are on another planet. The USSR collapsed, east Germany collapsed, Cuba is a joke, China is capitalist, you are living in fairy land.

The government may support a lot of research but the government’s tax base derives from entrepreneurs who create a healthy free market. No socialist utopia exists and you live in a good society because of economic freedom. None of this is news to most people, and me telling you this I guarantee will make no difference to you given how brainwashed you seem to be.

I think that setting a price on something is best considered as a form of speech, even if it isn't exactly the same thing. A price is a statement of the value you believe that a thing has. As a free speech advocate I believe people should be able to express such value judgments freely with few constraints.

A price signal is similar to other signals we can make with speech, in that it has the potential to change behavior for good or bad. There have certainly been many bad signals via ordinary opinion that have caused harm. But most of us believe that the net benefits are such that bad speech should rarely be suppressed. I think that the same is true of bad price signals.

It isn't that well crafted laws cannot differentiate between good and bad speech or good and bad prices. They can. It's that such laws are the exception rather than the rule. So it's better policy to decentralize such decisions, so that bad ones can't be made for everyone.
Most suppliers cannot simply produce 2Y the goods at the same price. Switching lines involves retooling and, risk, and/or overtime, all of which are expensive.

If that switch can be done for under the price cap, then the price should remain under the price cap anyway due to competition. If it cannot, then shortages will result.
True, and this is a counterexample to my claim that the parent would retain the symmetry. I think it can be refined though:

The parent still has hor/ver mirror symmetries, and the solution rotated is also a solution. So there is a set of (in this case two) parents that is invariant under the same symmetries.

In general, a parent should still be a parent when any of the targets symmetries are applied. (But it wouldn't necessarily be the same parent).

This can be captured in a SAT by insisting that any symmetry of a solution is also a solution, which adds a lot of new constraints and no new variables, so should help with finding.
In other HN threads, we're discussing how to hack up ventilators to meet the anticipated crushing demand. Another option to be pursued in parallel is for existing ventilator manufacturers to ramp up production.

Are there some models which allow for quicker production because they have simpler designs, everything is sourced locally, production lines do not require exotic high-precision tools?

If so, are there ways to get the companies which manufacture such models the capital and anything else they need ASAP?
> Let's say it works, and more homeless people do move here to take advantage of it. That is a good thing. God forbid ol' San Francisco should become a continent-wide renovation center for human lives, eh?

Obviously something is wrong with your calculations, otherwise that would be reality. And the error is in the assumption that a tax base of a single city will sit around and pay the amount of money required to rehabilitate and/or house the mentally ill for the nation.

Labor is extremely expensive, especially labor where one might have to deal with dangerous mentally ill people who may have criminal pasts. It’s ludicrous to suggest a single city could possibly tackle the issue and shoulder the tax burden of the rest of country shipping them it’s most destitute citizens.

This is not even taking into account the legal matters that would need to be resolved on a federal level with involuntary housing of the mentally ill homeless population.
I would argue that the supply/demand pricing isn't responding fast enough to the hoarders. If the price was fully elastic, as people began to hoard lysol wipes, prices would rise on the hoarders and make it much less profitable for them. But prices aren't rising correctly, much like an artificial price ceiling would do, making it possible and profitable for hoarders to create a shortage.
> If, under normal market conditions, producers already make X amount (of , say, toilet paper) due to Y demand at price Z, when the demand spikes to 2Y, if you can produce and sell 2X goods at the same unit cost, you can double your profit without raising the price at all.

This doesn't accurately reflect how the cost would scale. X isn't easily adjustable - it reflects annualized wages, depreciation of production line that is sized for production amount X, etc. Equipment sitting idle is wasted money, so production lines operate close to maximum production already (or at least nowhere near half capacity, that would allow 2X production)

idk if other servers do this, but online-go.com has an LZ instance which analyzes your game, showing how much it thinks a certain move has swung the win/loss probability and where it would have preferred to move.

haven't gotten objectively better from looking at it yet, but its super interesting. the ui is pretty nice, showing estimated probability vs move number - letting you find the places where the game swung one way or another any playing through those sequences.

I guess the only other thing I would ask for studying is move-by-move analysis for alternate sequences
And only in a state of emergency. If you’re in Egypt, that can be thirty years or more. In California, probably not.
>the costs of manufacturer's switching over production is going to wind up much higher then any profit they can make once they're tooled up

This is not necessarily true, especially if we consider that the pandemic may continue for a few months, and people will be using orders of magnitude more hand sanitizer and masks than before.

> the guy with 11,000 bottles of hand sanitizer has no use for them, outside of the extremely limited window of people panicking due to uncertainty.

He distributes supply over time. Instead of everyone panicking and buying up all the supply at time T, the scalper buys up some, and then gradually sells it at times T+1, T+2, T+3... Scalping is arbitrage between current demand and future demand, and ensures more supply is available when people need it in future.

>But really, whether anyone believes this can be viewed through a very different lens: multiple times in the past week, US exchanges have ceased trading due to automatic circuit breakers from 7% drops in the market.

This is comparing apples to oranges. A circuit breaker is not a price floor except in a very limited sense; the price is free to fall further the next day. I don't think many people would object to a rule like "the price of masks can only rise 10% per day".
From the law:

“However, a greater price increase is not unlawful if that person can prove that the increase in price was directly attributable to additional costs imposed on it by the supplier of the goods, or directly attributable to additional costs for labor or materials used to provide the services, during the state of emergency or local emergency, and the price is no more than 10 percent greater than the total of the cost to the seller plus the markup customarily applied by the seller for that good or service in the usual course of business immediately prior to the onset of the state of emergency or local emergency.”

I am glad they included this language, even though it is a bit sloppy. What I am referring to is that yes, costs can increase dramatically during an emergency, however, the “markup customarily applied” could also change in dramatic ways.

One of the aspects of the theory of pricing is to include in the equation variables to address support, business continuity, expansion, disruptions and other “nonlinear” factors.

In an emergency what might have been simple could become complex. This means it might be impossible for a vendor to maintain an ongoing supply or continue to offer services. And, given the current reality, if the consequence of providing the goods or services could be loosing your entire staff to a quarantine, your ability to maintain a supply might require a very different approach to pricing.

Given the severe consequences, this language could cause vendors to avoid exposure for fear of being destroyed by an uninformed claim. Which means supply would contract and prices would explode.

That said, the guy buying water at Walmart for $1 to then sell it for $5 should get nailed to the wall with rusty nails.
All I want to say is: sure, touch don't touch your face. But don't forget to open up the windows for fresh air, hold your distance to other people

The UK allowed the Cheltenham festival [1] to take place this last week as well, attracting 250.000 visitors.

The mere fact that the UK arrived at the same conclusions as Sweden does not make those conclusions any more valid or wise.

I don't think Keybase is getting a fair shake in this post. The author is using the ChromeOS Android app. This seems like a fairly unusual setup, but maybe Chromebooks are more popular than I think? Plus the low amount of memory in Chromebooks guarantees that this is probably not going to turn out well.

Most people are going to use the Electron App on either Mac, Windows, or Linux on a laptop with a decent amount of memory. Also, the part about no "GitHub integrations" is false too, because I'm looking right at githubbot that is maintained by the Keybase team. Maybe it doesn't support all the things the author is looking to do, but that is different than saying there is no GitHub integration at all.
That's a very good point : I also found that the core feature of configuration management - idempotency - actually becomes mostly useless in this case, as ansible applies a playbook only once.

I still use it as it allows more portability across OS releases and families (as in easier migration), but it also increases the complexity when creating a new task/role/playbook.

In that sense, Dockerfiles with shell-based RUN commands are much easier to manage.

Another advantage of config management over shell might be a better integration with the underlying cloud provider. For instance Ansible supports AWS SSM parameter store, which allows me to use dynamic definitions of some configuration data (RDS database endpoints, for instance) or secrets (no need for Ansible vault)
My colleagues run numerous projects that transfer knowledge between computational research, including molecular simulations, and wetlab research as a routine. Computational and wetlab experiments are reguarly designed to complement each-other.
Examples of numerous bio-phyiscs/bio-chemistry research done around me (ranging from research on ion channel dynamics [1] to drug permeability through the skin barrier [2,3], or cryo-em structure refinement just to name a few) strongly contradicts your experience as well as your final statement -- and than we've not even mentioned the drug binding affinity computations which is these days routinely done using molecular dynamics by both academia a pharma industry.

As an anesthesiologist and hacker, I love the enthusiasm here. I’m less concerned about the hospital use-case. It would be helpful to crowdsource solutions to address the need for ventilators after patients leave the ICU. Based on current practice patterns, some patients will undergo tracheostomy tube placement, and then need to be discharged to respiratory rehab facilities. We will need to increase capacity in this setting, and I’m not seeing or hearing anyone address this area. If we don’t solve this problem, we will find ourselves with a backlog of patients who could be discharged from the ICU, but with nowhere to go.
“While the pricing of consumer goods and services is generally best left to the marketplace under ordinary conditions...”

They forget to mention that the marketplace is highly optimized at the foundation to make this bullshit.

There’s no open marketplace. The government protects concepts like inflation which is the deflation of buying power of the masses to prop up the power of aristocrats.

I have zero qualms with government stepping in to actually create some pricing competition.

Financial “value” is not a property of an objection reality. It’s a human ideology. No one in economics disputes this.

And somehow we’re convinced old gits dumber than us, outnumbered us have sold us on truth of markets.

They pray on confusing and controlling our innate behavior to model our future. “Oh guess my model will be these cube walls forever.”

And I’m talking specifically about the bulk producers of basic human needs, food, material supplies, medicine.

How shallow and self aggrandizing America as a culture is is on display right now.
