I'm not sure "self-styled" is quite right here, he is a card mechanic, that's the term for someone who cheats at card games by manipulating cards, and he demonstrates exactly those techniques.

Ah, thanks. I didn't know that was a common term.

To illustrate just how common it is, the first deck hold most card magicians learn is called the "Mechanic's Grip" [0]

> And unlike with object recognition that uses cameras, there are no privacy concerns, or need to maintain line-of-sight or good lighting conditions. Radar works through different materials and in the dark as well as the light. Wait, what? The ability to see through walls and not require line of sight leads to fewer privacy concerns? Seems to me the privacy concerns are significantly greater for radar than facial rec…

Firstly, I think (though I could be wrong) that when they talk about privacy concerns they mean the sort of concerns the average person would have about having a camera about... I.e. naked or compromising pictures of themselves getting leaked. I would guess this wouldn't be a problem with radar as it doesn't create images. Out of curiosity though, not having much knowledge on the subject myself, what would be your se…

Creating images with radar sounds like a fun GAN project. I mean we are already coloring animes [1] and line-arts [2, 3].

I've noticed this competency in google photos as well. Though surely it is using the photos of her in between those ages to extrapolate(?)

I don’t think so. It managed to recognize an old baby picture of myself and the only other pictures of me are as a mid thirties adult.

Well props to the team behind it!

If the technology were fetishised, the tech itself would acquire the status of fetish, which isn't the same as the tech being used to ends of fulfilling a fetish (e.g voyeurism). Some brands arguably promote technology fetishism, but fetishism isn't necessarily sexual, for instance the theory of commodity fetishism.

Just to be clear, I'm talking about weird dudes with prurient motivations scanning unconsenting people through the walls of their homes.

You mean cops?

Can a low power 50Ghz signal penetrate a wall?

with patience and if designed to detect below the noise floor the power level should not matter

If a sheet of paper is roughly .1 mm, then this must be running over 300GHz, or what is more commonly called infrared light, no?

good catch, probably it's not actually resolving the individual card layers, but using the Lambert-Beer law of attenuation, after callibrating on a deck of known number of cards?

Crazy fast video that is hard to follow, but thanks for the link.

It is difficult to cramp everything into a 3 minutes video that's why. The first part is just the summary so it might be really fast but the next part should be slower.

Inane gos, but I see a Monzo card at 1:35. That means this was very probably developed in the UK? I have to say the branding choice for the colour of that card was a pretty brilliant move.

Great spot, the blue card is Barclays, black card is CIMB and red card is Maybank.
