How nerds and geeks contribute to the global killing machine

they think it's a novelty , first thing it will be used for is to kill people in false and illegal wars in the middle east and elsewhere

MIT researchers have developed WiFi technology that is capable of seeing a human through an obstacle ‒ like a wall ‒ and reconstructing the image by analyzing the reflections from the signals. The technology has a variety of practical applications.
The new device, called RF-Capture, is based on previous methods of capturing movements across a house. That technology is currently used by firefighters to determine if they need to save anyone in a burning building, as well as by mothers to see their baby's breathing, Popular Mechanics reported.

It was developed at MIT’s Wireless Center, which is hosted in the Computer Science and Artificial Intelligence Laboratory, or CSAIL. Previous research from the lab developed a wireless system to detect gestures as subtle as the rise and fall of a person’s chest, allowing them to determine a person’s heart rate with 99 percent accuracy.

I thought this was done decades ago.
SWAT, if they don't already, will be getting these.

No more grenades on baby's.

No sir.

Just 20mm depleted uranium.

they also excuse stuff with some fringe purpose like looking for people stuck in rubble, but the main application will be used for killing.

Death and destruction are always the main considerations for the powers that be.

I think what you're seeing here is a cheaper alternative to Thermal Goggles.

Therms, like night-vision filter out everything outside of a narrow infrared band which can but done with a cheap cell-phone camera, but to get the contrast the imaging device needs to be kept at extremely low temperatures, which takes an advanced liquid cooling systems and a lot of power, which ultimately drives the price sky-high.

Thermal imaging's been around forever.

This is radio waves bouncing about. And theoretically they can penetrate what thermal can't. Even a cold-suit can beat thermal but with wifi you'd still see the images.

[Winnson]

Sonar? Radar?

Sorry, I don't exactly see this as mind blowing. It's old technology.

[Winnson]

Bats see this way.

Happy Halloween.

Wifi is actually in the Microwave band. Lower Frequency, Longer Wavelengths means better penetration of solid objects, but this isn't everything. There is a lot of noise in this spectrum and there is no reason you couldn't shield against it.



I wouldn't expect a functionality improvement over Infrared Thermal, the benefit here is low cost because it doesn't require onboard cooling. You can mod your cell-phone camera to do Night-Vision with a couple of cheap plastic film filters.

I read another article about this and it said that the current experiment grabbed the data and then processed it offline later in the lab but not in real time. So it's probably just scare tactics BS.

That's pretty lame.

Nerds are now trying to make robots that solve puzzles
this is what happens when you teach people to "change the world" and "do stuff that's never been done"
