I've noticed, recently, that literally every major chain store I go into blocks my cell signal. I get full bars outside, perfect LTE, and about 5 ft past the glass doors, I'm suddenly cut off. Specifically, Meijer grocery stores and Home Depot are the worst offenders. Coincidentally they offer free in store WiFi to track me with, so I turn off my wifi radio on both smartphone and smartwatch before walking in the door…

Most businesses use metal studs to support interior walls, though I doubt their ~2 foot spacing would block wifi or cellular RF.
In terms of active cellular jamming, that should be pretty easy to detect -- by standing in an outside doorway where you'd be exposed to inside AND outside signals, and then checking if your cellular bars fade out. That should indicate that you've been exposed to an internal jamming signal, since the external signal should still remain.
It's hard to imagine that the advantage to a corporation of isolating the customer's phone would be worth the risk of FCC prosecution.

#85I'll repeat it again. - Machines that see through walls are coming - Microscopic drones are coming - Mind-reading machines are coming - Private key cryptography will become obsolete Fighting for privacy is backward. It's unsustainable. We must work toward a post-privacy world. The sooner we do it, the smoother the transition will be.
I'm scared. What is a post-privacy world?
A world where people freely share knowledge and resources.

#88Awesome. I was playing Batman Arkham City yesterday and this is "Detective Mode" in the real life!

#89Love it. This is a game mechanic / movie superhero device that's been around a long time, just love the fact that this does it so simply and with so much promise. As sensitivity and the quality of the neural net increases, combined with AR, this is going to make super soldiers out of SWAT teams.
And this is why you build a shipping container house -- free Faraday cage, built right in. Not mention that it's not hard to convert shipping containers to meet California earthquake code, or so I've read.
Other than bolting crap down wouldn't that basically consist of making sure it won't tip over?

The skeletons appear to have very long legs, but no torsos. I wonder if it was made intentionally that way to make them look less serious.
I suspect the articulated pose and motion of their animated stick figures were extrapolated from progressions of articulations of limb poses that were learned from the light-based training videos, and then they were overlaid onto the wifi-based signal of only the moving trunk.
All that animation does look cool, though.
