Tamper-sensing meshes are electronic layers that detect an attacker drilling or cutting into a device. There isn’t a lot of public information about their construction, so I did a survey of about 30 devices with such meshes. In this talk, I’ll share the results of that survey.


This talk tells the story of how I tried to solve a problem - and in doing so, understood how push notifications actually work. Why my first approach didn’t scale. Why almost every app uses Firebase or APNs. Why even Signal knocks at Google’s door. And why, since the Wyden letter of 2023, this is a documented privacy problem: “We kill people based on metadata.”

Creativity is that which seeks to enrich the individual (and perhaps others) without intruding upon or limiting the choices of others. Destruction is that which seeks to enrich the individual (and perhaps others) by intruding upon or limiting the choices of others. Creativity requires and nurtures self-discipline. Destruction seeks control. The cost of that control often comes in the form of disorder. Or at least that is how it would be experienced by everybody outside of the destructive force.

It is therefore authority over others which is the destructive force of the universe.
