Even though the service only costs about $0.50 USD/hour the price still doesn't seem justified by any potential cost savings. Unless the store is averaging two or more stolen sodas per hour and the service is reliable enough to catch/prevent those two stolen sodas every hour I don't really see the value proposition to the store owners other than employee surveillance.
Valid points, but also you don't have to pay maintenance expenses or property taxes on your REIT.
I like the idea of the lemonade stand representing different parts of a business.

COGS are the parts of a product that can be relatively easily tracked per unit. So lemons, water, sugar are your COGS (cost of goods sold).

If you sell lemonade at $1, your revenue is $1 per lemonade bottle.

If your COGS is $0.40, your gross profit is $0.60, also known as "gross margin", or a 60% margin (IIRC, I always kind of forget how these things are calculated)

Operating profit gets trickier: you add in all the bits of your business that you're amortizing over every sale. If you have a $10,000 juicer that squeezes lemons for you, and you EXPECT the juicer to last for 1-million units of lemonade, that's $0.01 per lemonade, so you subtract that out of operating profits.

This $10,000 juicer, is what Nick87633 calls "capital expenditure", or CapEx as it is sometimes known. You need to buy this to "start" the business. In theory, you can sell the juicer for a depreciated value if your business goes under. (Ex: If you sell 500-thousand lemonade and then go out of business, you could make the argument that you can sell the juicer for $5000 as your business goes bankrupt).

As you can see, Operating Profit has a lot of "opinion" in it: you estimate the value of your equipment if it were sold and/or the cost of replacement if it were damaged. (Ex: hurricane wipes away your lemonade stand and juicer. How much will it cost to replace the juicer?)
Not really. Plus that’s exports - so it’s other countries buying it.

>No Amazon definitely destroys most returns. I was informed that anything you can take to a Kohl’s is destroyed after return.

I don't think the existence of a Kohl's dropoff option means Amazon destroys 51%+ of their returns. Examples of people buying pallets of Amazon returns that are not destroyed: https://www.youtube.com/results?search_query=amazon+returns

Like many retailers, Amazon outsources many reverse logistics[1] operations. Some returned product is sold off. Some is destroyed.

There exists a second hand market online, Amazon just don't want to feed into it.

Probably the scarcity by waste leads to more profits than trying to recycle, as the environmental costs of waste aren't paid by Amazon.

That's not true -- you were informed wrong, sorry.

Tons of items on Amazon list "Amazon Warehouse" as a cheaper buying option, which are literally the returned items they're reselling, with a listed condition determined from inspection. This includes items that were returned at Kohl's.

Amazon destroys some returns, but that happens after the inspection process, if they determine the specific item was damaged enough that it's not profitable to resell.

I thought Miranda/Haskell were much more in the vein of Lisp/Lambda Calculus than Backus's ideas, which were more radical and not widely adopted to this day [1]. I always thought of Haskell as simply what Lisp would be if it had implemented a typed lambda calculus rather than an untyped one.

All this is assuming you have liquid funds to invest or have some other access to credit. The only realistic shot your "average joe" has at any sort of reasonable leverage is getting a mortgage and buying some property.

Obviously if you're already rich then you have lots of better options to become even richer (like the ones you've mentioned), but they're not really open to your "average joe", if for no other reason than that most of them require you to be an accredited investor or require a high minimum investment.

Is anyone else here being asked about their opinions on UFOs a lot at the moment? I know I've been finding people in my family and friends suddenly becoming convinced that aliens are visiting Earth, and have been for a while.

This past year, more and more frequently, I've had to explain that just because the US government has a small UFO program and just because there has been some odd reports of UFO sightings this doesn't mean aliens are actually visiting Earth, or that this explanation is even remotely likely.

Given how politicians, the media and tech companies have been putting so much time and money into cracking down on "conspiracy theory" content recently it strikes me as odd how this conspiracy is apparently perfectly fine by the standards of the very same media companies and tech companies cracking down on other conspiracy content. Some influential figures have even gone so far to simply declare on platforms like YouTuve that they believe aliens are probably visiting Earth and that the government is likely actively trying to cover this up. In some cases I've seen people suggesting that the aliens are trying to send us a message about (global warming|nuclear weapons|[some other potential dangerous technology]) and as far as I can tell this content is never restricted. Additionally, warnings or links to Wikipedia are never added to the content as you might see when it's content about 5G, COVID or flat Earth theory.

Does anyone know why so many people in power are encouraging conspiratorial thinking when it comes to UFOs while seemingly holding a completely different perspective when it comes to other government conspiracies? To be clear, I'm personally fine with people believing and discussing whatever they want to online, but there seems to be a double standard when it comes to alien conspiracy theories.

It really grates on my nerves how easily people jump from "UFOs" to "extraterrestrials" in this topic. You'll see it everywhere, "OMG, the Pentagon just admitted UFOs are real and nobody cares! How crazy is this pandemic that nobody cares we aren't alone in the universe?!"

Nobody ever denied that there are Flying Objects that are Unidentified. It's just stupid clickbaitism.

Additionally, I find the assertions that "these things move in impossible ways" to be extremely disingenuous. The footage that gets released is universally very bad. It's low resolution, often shot in infrared transformed to visible light, being taken from aircraft moving at a high rate of speed, executing their own aerial maneuvers. "Oh, but these are experts in the field saying this". I know some of these experts. They aren't experts in every single system between camera sensor, tracking systems, and the limits of airframe motion.

There's one particular video (I can't find it right now) that shows a supposedly "impossible" roll and change in direction. Or, it could be that the filming aircraft rolled and the camera tracking system hit a gimbal lock situation, either because the tracking motors aren't able to move as fast as necessary, or because the tracking math wasn't implemented correctly.

But again, "glab glab glab, these are experts, I can't believe they'd make such a basic error as using Euler angles instead of Quaternions to calculate the SLERP." But I've seen some of this code with my own eyes. YES! A lot of control system engineers apparently don't know about Quaternions! Just because game developers do doesn't mean the majority of control system developers do. There are innumerable cases of things that people would consider "cross-domain knowledge" that doesn't actually end up crossing because of institutional momentum and industry insularity.

We like to rah-rah our military industrial complex as "the most advanced in the world". That doesn't mean it's the most high tech, best equipment possible, or that the best equipment was even installed on these aircraft.

Do you know anything about how government procurement works? "Military grade" often means "already 5 years obsolete by the time it hits the field". The tracking camera in something like an F-18 was not built in some Manhattan Project-style operation. It was built by a contracting firm who won the lowest bid. And they probably put their A-team on the avionics and the leftovers on everything else. They probably had just-out-of-grad-school electrical engineers who specialized in camera systems and only took the minimum requirements for control systems. They almost certainly did not hire the best experts in the field just to make a 1% component of the project, especially one that was probably designed to be replaced in 10 years under a new contract.

Currently, each country does its own QR thing, a fair amount of which is just a link to some .gov.* website. Unifying it under one model makes sense. It makes it easier to verify and issue new EU QR codes. Otherwise, when presented with a proof, verifiers would have to know how to properly verify 20+ different QR codes.

So we've got two realistic options: 1) non-EU countries teach people their own and the EU verification method, or 2) non-EU countries offer a way to "convert" EU QR scheme to their own at the point of entry.

It's similar the other way around as well, because non-EU countries could either start issuing EU-compatible QR codes, or recepients could "convert" them to the EU-compatible QR code at the point of entry.

I want to clarify because a lot of people seem to be confused about what's happening here.

"Just run" is tracking your metrics. You can STILL use the treadmill without it, you just won't be getting information on the run like your pace, calories burned, power output, etc. The treadmill isn't bricked, it's just not providing metrics. If you have a garmin watch or insert fitness tracker you can still get info from that.

I can understand why people would be annoyed by this change, and I would hope they add the functionality back in the future. But everyone saying it's "bricked" needs to take a deep breath.

Amazon does sell/auction pallets of products, but it's probably their own inventory (not sure).

So most likely they won't do it for legal/logistical reasons.

Remember that Amazon doesn't move a finger if you don't pay them.

I don't see people paying amazon to have their products auctioned and amazon profiting from it. Neither I see how Amazon would split the bid between sellers. Who would be liable for that item?

You're not naive, you have products being mande and shipped from China to be destroyed in Amazon Fulfillment Centers. It's absurd.

I don't think it's a "belief" but a fact when we have all these conspiracy theories about the vaccine floating around.

1) Imagine if the US government was able to require social media or news sites to take down posts that spread disinformation about the vaccine. We'd be at herd immunity. But alas, an uneducated opinion about the vaccine is equally as important as a scientists with decades of experience in the field. It is a strength, and weakness of freedom of speech.

2) And now imagine that a foreign government can pump misinformation about the mRNA vaccine (China and Russia have been documented to do so) and shape opinions on any topic.

> isn't always a price point that is both low enough that people are willing to buy the cheaper returned item, but still high enough that it's profitable for Amazon to continuing stocking

I don't think this is how the prices on Amazon Warehouse are set... I suspect Amazon or Amazons third party sellers consider most warehouse sales to be a lost sale of the 'new' item. That means it's better to destroy the item than sell it at a discount greater than the production cost of a new item.

Thats why you rarely see discounts >30% in amazon warehouse, despite the fact any price over a few dollars probably pays for the storage and shipping costs.

Remember destroying items costs money - in many countries there is a tax on landfill, which for many items can work out about the same cost as shipping it to someone at amazons scale.
