An aircraft's Flight Management Computer uses a Kalman filter to combine the data from all available sensors (GPS, IMU, altimeter, ADC, VOR, DME, etc.) to compute the position of the aircraft.
But they're also in the business of responding to search with facts.

I love what sia is doing, however I was never clear why sia wouldn't have made siacoins inflate proportional to MB*seconds available?

It seems like producing some public dataset (the blockchain so far for instance) and some proof of work that is reasonable to do once and store, but unreasonable to produce for each proof of storage, make the proof of work tied to a private key and then give each user the ability to mint new coins at some discount rate for storing the blockchain.

There are a couple constants there (the cost of the proof of work, the discount rate for storing the public info as opposed to a file contract) that need to be set correctly, but for some values the cost of the token should be pushed down to the cost of storing a certain amount of data for a given time.

This would give a coin that is pegged to roughly what you want the contracts denominated in and would encourage network utilization.

Are the constants too hard to choose (you'd probably need to modify the proof of work and discount rate)?

What are y'alls thoughts?

EDIT: sorry this is not the best description, I can try and find some of my older better write ups of the idea if it's not clear what I am trying to say.
> Is the experiment really over when politically-adjacent threads are still getting flagbombed and removed?

Yes; that was happening before the experiment, too. Most general political news has been officially OT on HN long before the experiment, and remains so under the general guidelines. The experiment was effectively a ban on that small subset of political content that would otherwise be generally within the guidelines.
Google doesn't have anything pertinent, although there are plenty of cases of the fellow at the lotto counter stealing tickets. That's why you always, always sign the back of the ticket and keep copies.
Good critic, well done.
This is a positively fantastic explanation. One of the best I've seen despite being so short.

Minor nitpick: It might be a bit more clear if the terms "F", "s", "v" were explicitly defined, as well as a sentence explaining the matrix M inversion. It's really great, but when I read "our prediction formula F could be as simple as s = v*t_dot" I immediately think "F? was F defined earlier? Did I miss it? Also what is s?".

[overall, really great explanation, bookmarked]
Because recent buyers are among the prime suspects for abuse, since some people will exploit retailers' lenient return policies as a free rental service. They'll buy something expensive, use it a handful of times during the conventional 30-day return window, and then return the used, depreciated item to the store for a full refund.

This item then has to be liquidated or refurbished, but even if it didn't, you've still probably lost the margin you made on it just by handling the return. Margins per unit are in typically in the realm of a few bucks, at best. Pennies count in retail.

You can get away with this a few times, but more than that, and a backend system like this will flag you as a "serial returner" and instruct the staff to refuse your return.

It'd be great if they could make it easy to allow managerial override, but unfortunately, many managers or other store employees work in cahoots with civilian accomplices to rip off the retailers with this type of scheme.

For them to be wrong, they'd have to have an opinion. Why do you think people watching a video like this have a strong opinion one way the other? Maybe they don't and are just looking around.

"Last year, McDonald’s said it employed 235,000 people, including corporate and restaurant workers. Each of those people generated $97,000 in revenue, compared to about $65,000 the year before."

I don't understand the problem, McDonalds is not in the business of helping its employees, it is not in the business of creating quality, healthy food. Its business is squeezing as much work and money as it possibly can out of its workers and customers. This is a huge success by that metric, and I am sure it is the only metric the upper management really cares about.
Not really. Sure, it is proof of purchase, but we are talking fraud. Lots of folks throw receipts away.

These folks searched the trash cans. Got receipts out that said method of payment was cash, stole the item and "returned" it. Yet another scam is to take such receipts from the trash, buy the item at a discount, and then return it to a more expensive store.

Sure, the store can see the item was paid for by someone, and even see the store it was bought from. But it can't know if the person just found the receipt and is returning stolen goods or goods bought elsewhere so long as the barcode matches up.

It's good. Let's make sure the following conspiracy theories and extreme views are highlighted:

Anything about men's rights, "rape culture", white "oppression", "72 genders", marxism, neoliberalism, fascism, Antifa, conservatism, libertarianism, white nationalist, black nationalism, "Irish" nationalism, hindutva, islamophobia, islamophilia, Catholic church paedophilia, pizza gate, Russia collusion, 9/11 was an inside job, 9/11 was by Al Qaeda, George Soros, Koch brothers, uranium one, Castro Trudeau, PewDiePie, Alex Jones, Rachel Maddow, Sean hannity, morning Joe, ... Just to begin with.

It would be nice if the list of conspiracies and extremist views was a open source list so that we get an honorable and democratic process of deciding it as a people and community. I am sure we as good human beings will be able to peacefully maintain such a list. I wouldn't mind the great overlords of YouTube to maintain such a list either.

No, I definitely wouldn't say that that follows.

It sounds like you might want a different kind of forum than HN. If every political outrage made the front page, that would change HN into a forum about "what is currently happening in the United States". Such a site could be valuable, but wouldn't be HN. HN has a different mandate, which it's our job to stick to.

There's room for lots of kinds of website. I think a forum dedicated to intellectual curiosity has a right to exist, among others; and if HN is to be that, it has to be preserved actively, since the default forces all point the other way. User flags are part of how HN preserves itself. Yes, there are exceptions, but those need to be infrequent and have some unusual quality that raises them out of the category of latest outrage.

The supply of outrages outweighs the capacity of this site to accommodate them. Rather than calling that disgusting and despicable (as happened a lot today), it would be better to find a different kind of site that can accommodate them, or perhaps even to start one.

This is a myth. Authism is a spectrum disorder and you don't meet the more disfunctional cases very often. A few percent are also savants but not everyone in the spectrum has some superpower. The severe cases are very crippling and place a heavy burden in the family (specially because the life expectancy is normal so you will not be always available to care for your autistic son).

Well then, I must have been unlucky with the brand I attempted to use as a flag for an opto interrupter - it definitely passed enough IR for the thing to not trip.

This looks like a good example of the 80/20 rule: 80% of our brain matter is dedicated to the hardest last 20% of IQ points. (Only being slightly tongue-in-cheek here.)

Also, there's probably usually a lot of brain matter dedicated to redundancy, memories, and enabling connections between ideas to foster creativity, and this person may be lacking in these areas in hard-to-measure ways. If most of our brain truly had no purpose, evolution would have selected against it forever ago. (Instead, evolution went through large lengths to keep our heads so big.)
That’s probably because it’s fairly widely known (in Australia) that if you’re bitten by a red-back or funnel-web spider that you seek medical attention, as you would for a venomous snake. A quickly treated bite is almost never fatal.

Manipulative people copy commonly know (often stereotypical) stories as cover to whatever they're really doing.

Real stories, and manipulative fake stories , would be almost exactly the same, because one is copying the other. The manipulative stories are often slightly more realistic or interesting as the person telling it has had a second chance to refine it from the original version.

> under the hood

Surely, we don't have to work with raw quantum electrodynamics when designing an FPGA, even though that's what's going on "under the hood".

Thinking that way, gets me wondering about different layers of abstraction along with the benefits and drawbacks of each. With FPGA programming, what levels of abstraction are available and what simplifying assumptions does each model make?

I've got in mind things like Kirchhoff's laws, where we assume perfectly conducting wires, discrete elements, a conservative ambient B field, and essentially DC current over the size of circuit elements. When those assumptions start breaking down, then we can drop down a layer of abstraction.
I think it’s because some people just like to help things get better. And there is no problem about this.

I made $3.35 and worked my ass off in 1985. I was genuinely tired, though not stressed at shift end. That 10x thing is pure bullshit. The extra stress is solely because their paycheck is needed to survive, versus for some extra money. I didn't have much idle time. Wendy's had a salad bar then and other things (manual cash registers, less automation, no credit cards, less prefab food, etc) that were arguably more work than today's world. Other stuff, like degreasing the floor at shift end can't be any better or worse now. Didn't need health insurance or other benefits though, and my paycheck went to clothes, booze, and computer/electronic crap. Stuff my Mom wouldn't buy. I wasn't stressing about how much my paycheck was.
I would imagine that the at system at MSG is similar to Ingenuity Sun Media's system that's been deployed across NASCAR[0]. (The NYT article doesn't identify the vendor, but how many are there?) ISM's system specifically looks at the number of people in the crowd and how many are looking at the screen. Additionally, it tries to identify demographics in the crowd. Which makes sense, because this is meant for mass advertising. Although, I wonder how much more accurate you're going to get with some geewiz face scanner, than traditional demographic information sources. (Lots of middle aged white men at NASCAR? You don't say!)

Update:
Apparently, you can get better info.

How do you start up these containers so quickly anyways? Do you keep some running hot, or delegate the startup to something like amazon's ECS? I've long wanted to run integration tests en masse in containers, but never figured out how to solve issues around long startup times.
The philosophical difference between the two groups is very interesting. I tend to agree with your take, and would greatly prefer to see advances made in reversible vitrification so it can be widely used.
Wow what a coincidence, I actually just had a terrible experience at McDonald's yesterday. I tried ordering through the mobile app and they got my order wrong. When I went to get this fixed, the employees were busy fixing 3 other orders they had wrong. There's a ton of room for human error when electronic ordering allows for more customization.

I can also see the reason for slowdown. Before, they had a cashier queue to control the flow of orders. Now with mobile and kiosk orders, they've pretty much tripled their traffic of orders while keeping fulfillment the same.

Slightly off topic, but to your last point: I've done some thinking about this, and the idea that a civil liberty granting you access to firearms will help in a government coup or if the government really comes for you seems laughable on it's face. Your best bet is not a wild-west style shoot out, but alliances. Local government, corruption in the national guard or local sheriff's dept. When the federal government comes for you, you don't need one (or 15) firearms. You need friends in high places.

Especially when you think about the studies on split-brain patients.

Well as a user of Amazon you have a vested interest in the documentation being correct. It is what other members of your team and organization will be referring to.

Well, the very idea that there is some timelimit on mitigation before the flaw is disclosed anyways is that "very weak tea".

However, overall, I agree with you. Person with exploit needs to compare the probable consequences of disclosing at time N vs. disclosing at time N+1.

If it's being exploited in the wild and users can meaningfully self-protect, disclose now!

If the vendor will probably have a patch in 2 weeks, there is not widespread exploitation of the vulnerability, and disclosing now will cause widespread exploitation, disclose in 2 weeks.

If the vendor seems like they will never issue a patch on their own (because significant time has elapsed), such that at some point in the future there's going to be widespread exploitation and you're only hastening that a bit, go ahead and disclose now.
It is neither the vendor nor the researcher’s place to make those sorts of decisions on behalf of the end user, while keeping the end user ignorant of the fact that such a decision has been made for them.
