Wow that's huge.
The beat frequencies in the first sample are really annoying.
That is a fair description of what is going on...
Drums make multiple non-harmonic overtones (long story) related to tension at each lug... Conventional drum tuners just measure and tune the lower first overtone note, or maybe the fundamental note. All the slightly different pitched higher overtones from each lug beat against each other causing the cluttered dissonant sound. When all the upper overtones are also in tune with each other, you only get the one clean series of overtones, AKA "clear"... hard to describe what it is, but easy to hear.
On the tuned/cleared sample instead of hearing a beat there's smooth decay of the overtones vs the fluttering beat of the first one.
yup, why ain't I rich?
Going back to the Rustoleum...
Walmart's security cams were tracking you when you took the product off the shelf.
they are actually working on using robots to keep shelves stocked and manage inventory turns. AFAIK the robots only roll around and scan the shelves looking for low or sold out SKUs, they don't actually physically restock stuff.. (I haven't seen any robots locally).
They performed facial recognition, without a match then.
doubtful
The cams, using that facial recognition, watched you buy it with cash and knew based on the time stamp what specific Rustoleum SKU you bought.
they surely have cameras recording the self-checkout area to help ID thieves after the fact... I would bet against them having (paying for) serious facial recognition, but that might be the first place that makes sense to ID repeat offenders with even crude facial recognition. Steal from me once shame on you. Try again, gotcha.
The parking lot security cams then tracked you all the way to you car and read your license plates.
From the license plate read they got your email.
From that point they knew where to send the spam email.
Sound far-fetched? Conspiratorial?
Sure it does.
I was in a hurry this week because it was about to rain (cats and dogs)... the door monitor stopped me because one item was not in a plastic bag... (their tell for perhaps pilfered goods. If I was actually going to steal something it would be easy enough to stick it into a plastic bag.. but i don't roll that way). The new puke who didn't recognize me stopped and scanned the barcode on my receipt, then scanned the suspect item, and saw that it was already paid for, all in a matter of seconds... In the past the door monitors were like airport security putting on a show and pretending to be effective. At least walmart is using that barcode technology effectively.
But the Chinese do this tens of millions of times a day to track their citizens every single move.

Full 24/7/365 surveillance with a social credit score assigned to everyone.
Rustoleum at Walmart is just the beta test.
Yes, that isn't all china is doing, they are working on some re-education (cough) and perhaps ethnic cleansing if that doesn't work with their uighur population.. They don't have gun control laws, they have knife (dagger) control laws for them.
But my local walmart isn't in china, and presumably they are smart enough to not try to sell me something I just bought?
