Over time, calling the customer service line back
over and over, she would piece together information.
The name on the account that shipped the product was
different from the one used on the credit card, she
discovered, all of which were different from her name
and address.
Even HTML5 web capturing works in a similar way. Once you give an site like Discord access to your microphone or screen it can pretty much access it whenever the page is open - granted it will show a little badge on screen by default.
A lot of users got tired of the on-screen badge being on all the time and probably set it to hidden (very easy to do) so not everyone is actually aware of when an HTML5 application is accessing a microphone/camera/screen.
A small aside: on the Mac, Micro Snitch [1] can let you know about any app that accesses the mic or webcam. It can use overlays, notifications, and/or just the systray to indicate that an app is using the mic/webcam. It also has an activity log that can you show past use.
It's actually not software at all. They use a glass surface between themselves and the camera with lights piped in the edges of the glass. They then use fluerescent markers to get the bright text effect.
Mirror the video image (or learn to write backwards) and viola.
"The lightboard itself is made up of a heavy duty frame, a 3/8” sheet of low iron glass (commercial name starphire,) and a string of LEDs to wrap the edges of the glass to shoot light inward to make the neon markers pop on camera."
They mention they don't preserve "heads" in specific but rather brains, and go into detail about how they can't separate a brain from a skull so they preserve the entire head. Wouldn't separating the head from the body cause similar problems of destroying information in the brain? Do they keep the entire body?
I know nothing of this field, is there any idea of how long "information" stays in the brain or any metric like that once blood/oxygen flow to the brain has been inhibited?
E.g. people found drowned in icy water with no pulse. "Six of nine survivors (66.7%) had minor neurological sequelae with Glasgow outcome scale (GOS) 5 (low disability)" (the rest worse). It's not clear to me from the table what the longest time with no breathing or pulse was among those six best-off survivors. But here's a popular account of another case: http://www.iflscience.com/health-and-medicine/child-survived...
Those were the top two google hits that came up. It's not my field, but it doesn't seem plausible to me that much of our identity is encoded in evanescent patterns of electrical activity or such. (As opposed to your short term working memory.) If you can nail down the molecules, the information is bound to be there in their arrangement.
