With wild and crazy shape lines. Ultra futuristic fashion here we come!
Time to carry a WiFi jammer
Well of course the Sapienza scientists would figure this out, Agent 47 keeps killing everyone in the labs
Reminds me of the Christian Bale batman movie where he could spy on everywhere from the bat cave. Seemed so far fetched it almost ruined the movie
No-one suspected Bruce Wayne's "free WiFi for Gotham City" initiative
It was very much not even far fetched at that point. 1984 wrote about the same kind of surveillance, and at that time it would have been pretty far fetched. It was published in 1949; the video camera was only 24 years old at that point.
You know, this, and the using wifi to see through walls stuff to me just immediately seemed to fall into "don't research this, it can only be used for evil".
I don't get why we bother studying these types of things.
We study it because EVERYTHING can be used for good or evil.
If we'd stopped researching anything that could be used for evil we'd never have gotten into the stone age
Yeah, like, why learn how to split the atom if all we can do is splode stuff. It's not like we can cure cancer or power things without emitting planet killing gasses or anything.
But, but, splosion make line go up. Splosion good...?
And this here folks is the true ending. No one there is going to stop it as always.
Congratulations! You are now fully fucked!
There is the draft dodger, he is located in building #52556 in this city, info updated 125 milliseconds ago. He left his phone at his house 5 states away, go get him.
you can also take a picture of a person with a camera that senses light beams
The most primitive of physics concepts, the transmission/absorption/reflection of energy, is completely unknown to most people it would seem.
95.5% accuracy is abysmal for any use case these people want to use it for
what if you combine it with other types of imaging

Wait… so the guys with tinfoil hats were on to something?
Except that the tinfoil hats don't work
Maybe wearing a different tinfoil hat every day would mess up a person's "fingerprint"
you might be onto something.
take a mylar square and place it somewhere random on your body every day.
Yep it has to be random to mess with the algorithm. You could have fun and cut different shapes each day.
Eat a piece of spinach and increase the iron in your body.
This is all beyond stupid and hysterical.
instructions unclear, I have glued spinach to my skin and the rabbits won't stop chasing me.
need further instruction.
Actually you've gone far enough to baffle the system.
I would say have fun frolicking with the rabbits?
Can I become obese in a day to avoid being fingerprinted?
I did that over 40 years.
Doesn’t help.
This has me wondering how my sack of potatoes body would look 🤣
Why would someone research something like this? God damn, like use your life for good, homie
You think if people who publish their work publicly didn't research things like this, they would just never be discovered?
At least this way, we all know about the possibility, and further research can be done to see what can mitigate it.
Everything is incremental progress in some way.
I remember years back someone doing experiments with Wi-Fi to see if a room was occupied based on signal attenuation.
This just looks like an extension of that.
Not everything is a giant leap
Well I heard about this and thought "this will be great for home automation", but I also know that someone was equally excited about using this to rob people of basic freedoms or being a fucking creep or both.
