Could be c't magazine accidentally played the mp3 version louder. Human's have a known preference for louder music, and will tend to prefer louder samples over quieter samples. Rumor in the industry is that this was a trick MS used to try to push the WMA format, that they encoded some WMA samples used in some publicized tests at +3dB above the source sample.
I was suprised to see the use of wiremesh in sand castle building some years ago. Same concept though. You add something that helps with shear strength and you can build much taller sand buildings. It’s really counter intuitive to see too, since the sand could clearly sieve through the mesh.
Ha! just looked up the video, seems it’s another practical engineering video I was thinking of
Most likely that’s the nitric oxide (not to be confused with nitrous oxide) that is a biproduct of vitamin d synthesis which requires UV light. It is a natural muscle relaxer and is generally considered good for blood pressure and heart health in general.
Having lived near the US border most my life, the way it was explained to me years ago, is that there is a strip of land at the border crossing, where you are in neither country. In this space, you are not privy to any of the protections you would be allowed were you in either the US or Canada. This is where you are taken when you are forced to leave your car. Part of the current controversy is that the US government is trying to treat this literal no man’s land as both international land as as federal land with the disparate charges they are applying.
Fun fact. Lack of parking is not a legitimate reason to attempt to drive past this region. I was once flagged crossing into canada on a day they were interviewing a lot of travelers. I spotted parking in what looked to me like an overflow lot on the other side of a fence, and when I slowly drove that direction sirens blasted and guns were drawn. Nothing gives you clarity like a gun pointed at you.
Whoever explained this to you has done you a terrible disservice. The border is the border - on one side you are in the USA and on the other side you are outside it.
If there was a strip of land where you are not in a country then how can CBP assert any authority? No, you must be in America. There is no "no man's land," and there is no such thing as "international land" at America's borders where no law exists.
This is generally true. What I find fascinating is the application of information that is not present in the data but that can be confirmed by the data. I’m thinking specifically of deblurring algorithms people use to recover text. If you can guess what font is being used in a screengrab with, say, someone’s bank account blurred out, you can take the i formation contained in the downloaded font and try combinations until you match the blur algorithm that may also be information not contained in the image.
What’s also crazy, is that even if all you do is black out the text, kerning alone can still be used to guess the correct text with some degree of accuracy. I worked on redaction software at one point, and these were very much the types of things we thought about when dealing with text.

I would argue that high frequency information is not missing in a blurred image, rather it's spread out spatially. Every sample in the blurred image is a convolution of multiple samples (i.e. high frequency data) from the originating source. Theoretically, it should be invertible, provided the exact function is known that does the convolution, but there are practical limitations, such as knowing how to apply the inverse operations at the edges and dealing with the extreme sensitivity to errors.
