Remember 1965? 58 years ago? The first official government report on #globalwarming for US president Lyndon B. Johnson? 1/2

@virtulis Let me try to restate what you're saying to make sure I'm understanding it correctly.

You are looking for
(a) a system that lets you quickly get yourself into a state where you can convincingly claim that you are physically unable to unlock it
(b) to an adversary who might be well-informed on this system
(c) but is otherwise unsophisticated and only has a limited amount of time and resources to spend on you.
(d) Crucially, you do not need to hide the fact that you're using this system or the fact that your inability to unlock it is a direct consequence of your intentional actions.

You are proposing what is basically a passphrase lock, except that the passphrase is intentionally impractical to remember and designed to be entered via QR code, which the user can quickly destroy when necessary to lock themselves out until they can access a backup copy.

If my reading is correct, I think your proposal is pretty good! You probably want to actually use the QR code to encrypt the app's database (as opposed to relying on it solely as a UI-level locking mechanism) to avoid making this easy to bypass via adb. For ergonomics, maybe consider supporting NFC tokens as well (I hear Russian banks are handing those out like candy, I wonder how easy those are to rip).

For related prior art, check out 1password's Travel Mode (https://support.1password.com/travel-mode/).

If you were to implement this, it would be crucial for you to be very very clear that this is your threat model. "Plausible deniability" has a bad reputation among modern cryptoengineers mostly because of overly ambitious/naive proposals that purported to address a stronger threat where (c) and (d) are not true or because (d) sounds implausible to much of the Western audience, but if people on the ground are telling you they're willing to live with (d) this seems reasonable.

First paragraph: "once upon a time, in a world not to different from ours, handmade clothing was the norm."

Comrade. Friend. I really need to tell you that clothing is still hand made. We just exploit people in the global south to make tons of it cheaply.

Having listened to Macron and Scholz at #MSC2023 yesterday and as much as I appreciate their support to Ukraine today, I can’t help thinking that just a year ago they believed Putin more than they believed some of their allies. Trust takes time to build.

This is Oleh Fedirets.

He is a Ukrainian University professor with a PhD in economics.

Because of Putin, he is now an anti-aircraft gunner near Bakhmut, risking his life 24/7.

War changed us all. Putin must be held accountable for Oleh not teaching at Uni this morning!

Folks who do _not_ use GNOME, a question for you!

This is a UI for switching between two options. Which one is currently active/selected?
