Whilst I’m sure there are opsec protocols that can do something to protect you from modern (military style) drones, it’s very very very hard to stop an adversary with a nearly unlimited amount of money and incredible technological superiority from keeping their eyes on you once you’re in their sights.

Yet, the US has pretty much been kept at bay from Irak and Afghanistan, go figure... In general, the US army is not equipped for guerilla-style warfare, and especially not on US soil. Local PD are another story on this point, but far less equipped.

In general, maybe. Here's a specific case: https://news.ycombinator.com/item?id=24520757

Agreed. To me the most disturbing part of the video is how the soldiers have become distended and desensitized from killing. They talk as if they are playing a video game.

I mean, they are, since murdering a human has exactly the same consequences to them as playing a videogame (none).

Even in the old days, I believe Lyudmila Mikhailovna was fairly desensitised, at least after the first hecatomb.

Bonus clip: https://www.youtube.com/watch?v=fuPX8mjeb-E (IIUC the song backing this patriotic video was, as composed in the 1980s, anti-war)

Detection and Localization of Multiple R/C Electronic Devices Using Array Detectors [1] Locating Noncooperative Radio Receivers Using Wideband Stimulated Emissions [2] A Practical Superheterodyne-Receiver Detector Using Stimulated Emissions [3] 1. https://ieeexplore.ieee.org/abstract/document/6857348 2. https://ieeexplore.ieee.org/document/6329437 3. https://ieeexplore.ieee.org/document/5699393

The book Spycatcher details how, in the 50s, MI5 developed systems to detect radio receivers. They fitted out vans and drove past embassies to determine the frequencies different embassies were tuned into. I think they also tested with fitting out aircraft, but it’s a long time since I read the book.

Of course there is also the opinion that tv detector vans were a hoax and would never work, so ymmv :)

https://www.theatlantic.com/technology/archive/2011/12/top-s... It was also known by the likes of William Safire that our satellites could "read the license plates on the cars of Kremlin officials." -- If untrue, please provide a counter source to many of the like statements as cited above. (You may be right, but it seems that many believe you are wrong)

I don't know if it would be effective at hiding you beyond the next few years when more comprehensive systems are in place, but I think a simple circuit that randomly blinks an IR LED would be handy. Something like an an LED throwie, but with random cycling. Put a bunch of them around and you'll probably screw up most cheap CCDs by forcing them to constantly adjust their exposure. Sure, a cheap filter can defeat them…

a) Having a large blinking marker draw attention to your area would already be highly noticeable.

b) that IR LED would have to be extremely powerful to overwhelm a camera that is looking at a larger area

That video was taken from far distance because the drone had to operate unnoticed in enemy territory; pretty sure that they had much better optics and transmission capabilities even back then, but it had to be very far from action. The distance can be roughly measured, if the bullets speed is known, by counting the time between the shots audio (assuming it's properly synced) and when they're seen hitting the area. To…

One thing which bothers me is satellite imagery. In the 80s, 30+ years ago, license plates were discernible from orbit. I often wonder, what if you had two distinct lenses, each with separate transmit? EG, both operating at once. Or multiple lenses? Now you could do things, potentially, such as use a high-fidelity lens to tag individuals. EG, license plates. Facial recognition. That sort of thing. Once tagged, anothe…

This tech is available to private corporations, and almost to individuals. If you've called a solar company to get an estimate recently, they have full 3-D LIDAR maps of your house from orbit. They can map out the trees down to the branch level and then model how much sunlight will hit a given spot on your roof if you trim them. I was on the phone with a sales rep from LG yesterday and it was a bit surreal: I knew she was looking at a satellite image of my house, so I was like "We're planning to cut that whole branch off the middle tree that's shading the south roof of our house, and we're going to thin the branches of the corner tree" and she could follow along.

Much of this is also available to private citizens on Google Maps too - my home is not visible from the street, so when we were buying it, we used the satellite imagery to determine how big a back yard it had, how much parking was available, roughly how big the decks were, and we could even see the previous owner's patio furniture.

That is one of those sentences in an article where you wonder...

"Did the author know very little about the subject, or does he know exactly what he has written?"
