  • That’s not how physics works. If you are really interested in such issues read a book on foundations of physics or history of physics to see how physicists arrived at the most famous equations (Einstein,Dirac, Schroedinger or Newton), they are basically “bets” guided by physical and mathematical assumptions, but that is far from being “proved” or “derived”, there are no rigorous proofs or derivations involved. The uncertainty remains until an experiment or observation confirms it or rejects it. There’s no such a thing as “proving” a physical theory, for the simple reason that any physical theory works in a limited regime or range of validity. Newtonian gravitation and General Relativity are both valid and succesfull theories within their range of validity, but they contradict each other mathematically, in one theory gravity is a scalar field and in the other is a tensor field, so you could use the mathematics of one theory to refute the other, so it makes no sense the concept of proving a physical theory mathematically. You only try to axiomize a theory once is well established, but it’s irrelevant concerning its validity.

    The carrier can track a phone without sim card but it’s not the case if you turn on airplane mode. The whole point of airplane mode is to prevent the phone from emitting any signal to avoid interference with critical aircraft instruments. I don’t see any company risking to circumvent such a critical security feature, it would be easily verifiable.




  • Twelve years ago Moto X was launched by Motorola, at that time controlled by Google. I had it and at any moment you could say “Hello Google, what time is it?” and it responded. I was constantly listening. All the time. And it was a perfectly normal phone regarding battery life or data usage. TWELVE years ago, imagine how much easier would be to implement that now, with more powerful and efficient chips and bigger batteries.

    From an article about Moto X back then: “If you want to take a selfie, you should be able to simply say “Take a selfie!” In short, your smartphone should live up to its name. That’s the goal with the Moto Voice and Moto Assist software integrated into the second generation Moto X smartphone. And to do that, the Moto X is always listening, for verbal commands from the user and also ambient cues of the context. That emergent behavior is spawned by complex interactions between the software and hardware”

    Only much latter I came to the conclusion that with Moto X Google was making its first tests on using the microphone for mass surveillance.


  • It gives me exactly the same message but I’m not using a VPN. When I use the external viewer option with mpv using yt-dlp I only get video without audio. I can download the video fine using yt-dlp and then watch it with mpv, but if I try to stream to mpv while downloading to watch it real-time it gives an ffmpeg error: can’t recognize format… weird.
