At the bottom of the page there's a link, "When ‘if’ slows you down, avoid it" [1], that discusses these exact questions. It's basically what @josephg said, but it also shows the assembly language for each version.
A year or so ago I bought a Hisense 65U88KM, which comes with Google TV. During the setup procedure it asked me if I wanted to enable the "smart" features, such as Google TV, the camera and microphone, or connect it to a network. I said no to all of them, and that was that.
Now it just acts as a dumb screen for my Apple TV box.
I did the same with a Sony A80L, which also runs Google TV. I even uninstalled the bundled streaming apps for good measure, although I never see the home screen.
It behaves like a monitor. I never see the TV UI unless I ask for it.
My LG could be configured to behave like this (and believe me, I am thinking about going that way).
I have a cheap FireTV which cannot be made to behave this way. If you disconnect it from the internet, it will still require you to interact with the (slow-ass clunky) OS in order to select a different input.
Your best case scenario with some of these smart TV's is the ones which run Android to replace the launcher. Possibly, this gets reset periodically, meaning you have to keep doing it.
Apparently there's a few Fire devices which can be flashed with LineageOS - I might try researching that and see if it is doable. A FireTV stick with LineageOS would be the best case scenario.
I find that most of those reset to some nonsense occasionally or whenever the power goes out. I make sure they have no internet connectuon, but I usually have to dig up the remote to get back to hdmi1 so my device interface will come back up. I accept the annoyance because I accepted the discount that they give to have all of the spyware crap on there that I am blocking. I wish they could sell something cheaper that is just a display, buy product managers will be product managers.
Brian Haidet (Alpha Phoenix) shows how he made a video of a laser beam travelling across his garage. From his description:
I'm using the technique from the electricity waves video where I used repeated oscilloscope measurements synced after the fact to produce "videos" of electricity moving down a wire. The only difference is that instead of measuring electricity waves, I'm measuring light emitted by a laser, bouncing off the wall, traveling to my camera, and landing in the window of a photomultiplier tube.
The January 16, 2024 edition of the CBC radio show "As It Happens" has an interview with Gerry Vogrincic, the doctor who bought the book in 2007 and just sold it.
There's a transcript of the interview here [1]. Search for "Old Anatomy Book".
The audio for the entire episode is here [2]. I don't recall how far into it this interview occurs. (I've sometimes found their interviews split into separate clips, but if that's the case here I don't know where to find it.)
