Note that this file hasn’t been updated in years and it’s not meant as a “stop every exploit” solution. It helps, though.

Pinchflat looks good indeed! Self-contained, no dependencies, unlike Tube Archivist which depends on Elastic which has a shitty licensing model (not in the spirit of OSI open source).

If you say it quickly enough it may sound plausible to some but this is not how battery technology works, as explained by @skilltheamps@feddit.de

Perhaps CryptPad fits your needs. It’s an open-source privacy-aware collaborative office suite and storage solution. It’s end-to-end encrypted, so even if it gets hacked no usable information is leaked.

A bit of clarification about the quantum might help calm your nerves: to observe something means something such as light must interact with the particle you try to observe, and that very interaction changes the result of the observation. It collapses the wave function, and what you observe is just one of the possible outcomes. It’s not as crazy as you may think, but it’s very understandable that it may at first seem magical.
