I don't follow. I'm sending (or trying to send) messages to my contacts. If I know their phone number, I'm going to try to initiate a Signal conversation with them. So I ask the Signal server for a signed prekey. Your argumen

Solution A does not compose well with how Signal does encryption. In order to make this indistinguishable, Signal would basically have to man-in-the-middle all non-existent users. And if one of those users signed up for Signal it would have

How would a messaging app work without contact discovery? You try a friend's number, and see if the message goes through? Well if that's what you want, then you can do this for all your phonebook numbers, and all the ones that go

All this is technically true. As long as you believe that you will never ever under any circumstance send the same video chunk twice under the same key, you get all the security guarantees of a real CPA-secure (=> non-deterministic) sy

Do you think it should be restricted to SaaS? I know of some desktop software with free or discounted licensing that I'd like to share too

I agree there are complications that e2e adds that makes it pretty much unfeasible for something like Zoom. But why is client-side compression not a solution to the problem statement here?

Aha, looks like it's using a salt and iterated hashing under the hood. Thanks for the link.

It looks like you're storing an unsalted hash of the database's password in the plaintext header of the database itself. Is that correct? If so, this is a really really bad idea

Finite implies algebraic. The other comment says that the converse isn't true.

A nit: "reals are a field extension of ℚ. They could be considered an algebraic number field..." This is not an algebraic extension. Pi is a "useful real number" and it is not algebraic over Q.

Microphones pick up harmonics of the input frequencies. So if the ultrasound white noise is a multiple of the human voice range, it'll get let through.

Why would you prefer this over, as another commenter already pointed out, a web standard like the CSS `prefers-color-scheme` media feature? A web feature like that works across websites, is better equipped to deal with user accessibility is

Abstract: Cryptography rearranges power: it configures who can do what, from what. This makes cryptography an inherently political tool, and it confers on the field an intrinsically moral dimension. The Snowden revelations motivate a reasse

But being an ordinary relay means you are still being used as a hop for people to connect to hidden services. Do you think hidden services are less ethically dubious than clearnet services?

This is not reliable for paywalled links. I can sometimes download paywalled content from my console because I'm behind a university IP block.

I like the idea behind this list. But is it seriously suggesting that I buy a Galaxy S3 in 2019? Does it even get OS updates anymore?

Where's the UB? It casts a boxed closure to a raw pointer, and then back to a boxed closure. There's no tricky introspection being done here.
