So, once you create a multi-thousand-node storage cluster, if you need to change some configuration, replace the whole thing? Even if you replace onto the same machines - because that's where the data is - that's an unacceptable loss of availability. Maybe that works for a "stateless" service, but for those who actually solve persistence instead of passing the buck it just won't fly.

I know of children demanding iPhones because with an Android is impossible to iMessage(or video chat) with their friends.

I also know cases where a child from a modest family spent the money he earned on Fortnite cash. There is a group pressure to own certain things otherwise you are excluded.

Anyway my main point is about some regular citizens fighting a giant PR(propaganda) campaign is not easy. I follow some of Louis Rossman videos where he shows how politicians debate the right to repair and it is so clear how Apple and big companies PR succeeded in having those politicians putting more importance on copyright over repair schematics(because trade secrete). preventing repairing consoles(because pirates) and preventing replacing bateries(because fires and explosions). How much money and effort is needed to make a contra PR move to show people that batteries don't just explode if the repair person does not a paper that he is Apple genius or that making repair components accessible and repiar schematics accessible will not make video games more easy to pirate. Then there is also the idea that if you have access to rep[air your tractor then you can do dangerous stuff , thing that is ridiculous considering you can repair your car and then use it on a public road (not like tractors that are mostly used on private property)
If heat is an concern, you'd probably want to spec a thicker gauge wire.
Many believe that one of the most important innovations of the last 10 years is the Rust programming language and in particular its borrow checker, which is the result of a long investigation by programming-languages designers into "linear" or "use-once" variables. The main inspiration for this long investigation was probably a paper published in 1987 by a French logic professor:

https://plato.stanford.edu/entries/logic-linear/#Int

(I read many thousands of papers on programming-language design in the 10 years before 1987 and don't recall anyone investigating "use-once" variables or related ideas whereas soon after 1987 many designers were investigating that part of the "design space" and citing the French logic professor.)

Also it was Scandinavian professors who invented object-oriented programming (via the language Simula in the late 1960s). So Europe remains more innovative than most of the world (and remains wealthier than most of the world as a result).

Ask HN: Is USA testing enough people for Covid-19?
They are an incredibly homogenous people as well, so generally, most are in favor of the same types of social programs, as they almost all benefit from them. Income inequality is incredibly low, some of the best in the world. So yes, most of the ruling class are the people.
Why are people like this? Everyone knew more testing (the subject at hand) was needed. The second the first case was detected in the US (January 22) there was instant coverage of the inability of people in Seattle to get tests. And there were no tests. And there remained no tests. And only now, as the US clusters have started to spread out of control, are we seeing a significant acceleration in test availability (c.f. the linked article, about quick approval for a new test mechanism). And we know this wasn't impossible, because many nations (South Korea, Taiwan, Japan) got this right and managed extensive testing.

Why are people resistant to this argument? We. Fucked. Up. It's maybe not productive to argue about recriminations at this point, but if so it's even worse to try to excuse it away or pretend that it didn't happen. It was a terrible mistake, and right now it looks like lots of people are going to die because of it.
So Taiwan had testing, central coordination and planning, and perhaps most important, had continuity in their health planning from SARS till now so they didn't lose that institutional knowledge gained over time.

> haven't seen evidence that e.g. Charmin is saying, "Thanks to higher prices, we're able to see more toilet paper"

Do you honestly believe that manufacturers are currently at 100% capacity, and have been at 100% capacity for years?

That's ridiculous.

Manufacturers always have spare capacity. One simple solution is that they can increase hours that the factory runs (ex, by giving overtime pay). Or they can delay upgrades/maintenance to keep things running longer, or any number of things.

> If you disagree with that, please present evidence of decreases in production

You are the one who is making the claim that manufacturers have somehow been in a perpetual state of 100% capacity. That is an insanely strong claim to make.

The idea that it is impossibility for manufacturers to take any action at all to increase capacity is the actual claim that would require evidence.

You are also ignoring things such as the amount of supply that manufacturers have stocked up. If demand temporarily increases, then they can sell that stocked up supply, that is in warehouses, until they increase capacity.

The world is not running out of toilet paper. Instead, what we are seeing, is temporary, local shortages, at stores, until the next shipment comes in.

Those stores will just increase the number of shipments.
Then the state of the superproject would depend on when the checkout occurred. That would be disastrous for consistency, you’d be unable to replicate a checkout later or elsewhere. The state of a repo after a checkout should only depend on the commit that was checked out.

Compiler writers are too hooked on loop optimisations now to give up on undefined signed overflow. I'm afraid the only clean fix is to augment the language with an actual `for` loop, with an immutable loop index and well defined start and finish values. Stuff like:

for (size_t i : 0..10) {} // Will go from 0 to 9 included.
for (size_t i : 10..0, -1) {} // Will go from 10 to 1 included...
// ...or maybe from 9 to 0 included?
// Not sure which is best.
> Mr. Colvin does not believe he was price gouging. While he charged $20 on Amazon for two bottles of Purell that retail for $1 each, he said people forget that his price includes his labor, Amazon’s fees and about $10 in shipping. (Alcohol-based sanitizer is pricey to ship because officials consider it a hazardous material.)

If it's FBA, he only has to pay to ship the items in bulk to Amazon. If it's FBM, Amazon actually gives you a shipping credit (though when I was doing it years ago, it often wouldn't cover the full cost to ship it).
I watched the entire thing, but I know close to nothing about Go. I found it frustrating that they didn’t attempt to explain what was so unexpected about some of the specific moves, but just focused on everyone’s reactions to them.

> Two problems; factories cannot surge up immediately and all of the actual gouging here is not actually making it to the manufacturers, it's people mass buying out stocks and reselling. So the supply side isn't actually seeing any increased price to increase their supply. The Econ 101 pro price gouging logic breaks down here because of that.

This may be due to the fact that the retailers are heavily threatened by government action, so they take no action to increase prices.

Contrast this with the must-have Christmas toy, which may otherwise be seeing similar unanticipated demand and suddenly the same retailers are incredible pricing experts.

The factories will need to maintain long-term relationships with these retailers and they may also have similar threats from government action.

More likely is that whatever slack there is in the supply chain will be exported to countries which have no such price control policies, because price-control policies do not address the underlying issues of supply and demand.
There’s a certain amount of baseline knowledge in university books that is very helpful such as MPT, DDM, DCF, bond prices vs yields, theoretical relationship between rates and equities, no arbitrage pricing theory, etc.

I remember this guy from China who gave an interview titled "To Hell and back" or something like this... perhaps its just to early for the western media to bring recovery stories. As far as i remember from the things i have read, recovery takes around two to three weeks, add to this the recovery period from a "normal" pneumonia wich can take additional weeks (my father had a light pneumonia last winter, so i remember...).

Perhaps in the chinese media / social media we could find more answers... anyone who can read chinese here?
If china allows those wet markets again I hope there will be international efforts to sabotage those markets, and even have sanctions on china if they do nothing to fight against those practices.

I've heard those farmers who breed those animals lobbied the chinese government to allow those farms. So in the end, they will not prevent those practices entirely. So it might happen again in a region where the government have less control. That's the scary part.

My total loan amount was ~30k for most my loans over 5 years. The initial loans were at 3.25% and whatever the perkins loan rate was, the later loans were at 6.8%, which was super ridiculous and I don’t think they stopped that rate until later. I preferentially paid off the 6.8% loans, the other loans are practically free money (interest rates below 2%) at this point so I pay the minimum.

This seems like a myopic view, like you fell in love with a backpack and built a worldview around it. Modern backpacking gear is extremely light, resilient, and comfortable. You can get packs that ventilate your back. The canvas isn’t really any protection at all from being thrown off a cliff, but a pack filled with soft stuff is. And the external frame is totally unnecessary if your pack weighs 20 total pounds because you have modern gear.

And then mix that in with a jab at disposable culture. You can take good care of a modern pack too, I’ve never had to replace a backpack because it broke.

Sorry to be disagreeable, I just think this comment doesn’t reflect a common reality. I’m no gear head, someone else buys all my gear... but I appreciate modern gear.

Ask HN: Where to go for accurate information on Covid-19?
I consider myself someone who is usually able to discern accurate sources of information. But this pandemic has made me question that, particularly when I hear wildly divergent facts about the virus. Can it survive on surfaces, or is face to face contact needed to transmit an infection? Are there asymptomatic cases or was that mis-reported? Partially want answers to these questions but also am interested in where to go to actually find accurate information.
This kind of comment isn't helpful. Of course, there have been ways to copy large files around since there were networks. What's new in this protocol enhancement is that this works within the context of a Merkle tree-based technology (upon which all DVCS's are based). To use your analogy, yes this is a wheel but it's built with rubber instead of wood and iron.
Is the cost of the old parts being replaced more than the new ones in terms of the technologies being used?

Skeptical that the incumbents like Bosch wouldn't have already tried this in some form they have the OEM EMS / fuel rail industry major market share.

As with all things mass-auto it's down to unit price economics vs how desperately do we need to put this in the cars to meet emissions regs.

About 2-4 seconds is all it takes my samsung 4k 60hz tv. It's the most basic of basic tvs, with probably tons of apps that want to spy on me for hulu, etc. If you don't tell your tv the wifi password it can't use wifi. If you have no-password wifi that's another problem, but you could even block the mac address.

Perhaps eventually tvs will have their own radios to spy on you against your will, but that's not what's been there up to now. The osd on my $300 tv can be turned off, and disappears in a few seconds.

More like “we don’t care about emissions because we only make 20 cars per year.”

It makes no sense to get all up in arms about carbon emissions from sports cars. As a fraction of the market, even if you include more mainstream manufacturers like Porsche, they’re totally inconsequential.

But of course, if you are really just using carbon emissions as a way to preach and brag about your morally superior lifestyle and/or political positions, expensive sports cars are a great target.

Ah, that's a clever workaround.
Sweet. Looked into the KWA's site, seems like a clear use-case. If we were to break down the build into achievable chunks we may have more success, and have a bigger impact along the way.

There's an immediate need for a single source of truth for all the locations where COVID-19 testing is available. Trump said Google was building it, but turns out they are weeks away from an MVP that would only cover the SF Bay Area. I propose we start by solving that problem.

Building on this, we can answer the question: what is the scope of the problem? Today, the CDC doesn't have an accurate count of the # of COVID-19 tests that have been performed because they don't have a way to collect that info from the growing number of labs that are performing the tests. Moreover, there's no way for anybody to know how many people have actually been tested, because the same person can be tested multiple times. We could solve this problem by crowdsourcing that information directly from individuals.

Building on this, we need to know where the sickest people are right now, and predict where they could be in the near future. This is crucial information for healthcare providers (like me) and public health officials alike. Without this information in hand, it's virtually impossible to know where to direct resources (like doctors, nurses, ventilators, medical supplies, testing equipment, etc.). We need to be able to track demand AND supply in real-time --> this is the point at which the project starts shaping itself into an Uber-like platform.

Building on this, we could enable individuals to post offers to help and for others to request assistance. This would allow people like your mom to lend a hand where it is a) safe for her and b) most needed.

The ultimate goal would be to build an open-source platform that could be used by communities around the world with little-to-no deployment overhead. Ideally, it would be possible to clone the repo, customize a few parameters, and deploy instances in less than an hour.

I'll flesh this out a bit more, and submit the idea as an Ask HN topic.
