That makes sense. In this case I think it would be interesting to analyze the state space for the network protocol involved.

Signal is applying SGX secure enclaves to engineer a new contact discovery server design. This is doubtlessly promising and innovative. My only question is the following: what prot…

I want to understand how this story makes sense, and I can't. If you put the facts together, they don't add up. First, here's the chronology. 1. Original Note 7 phones were blowing…

Ugh, thank your for posting this, I opened up the comments section to post exactly the same thing. It's incredibly annoying how misleading this article is. I don't know what the HN…

> Money? That's harder, unfortunately. It's hard to innovate when people want to cling on to what they already know. This is a core element of my questions that other answers are u…

My question sounds overly generalized, but indulge me: Can you think of any worthwhile/interesting software that is desktop-specific (Windows/Linux/Mac) and that does not already h…

Of course, I was only referring to vulnerabilities I could verify are real. Steve was paid two separate bug bounties and invited to a Cryptocat hackathon in NYC. I also consider hi…

I am the original author of the software you refer to. Before its complete rewrite (released two months ago), Cryptocat was based on a codebase that I wrote starting in my early un…

> Complaints about Signal are, unsurprisingly, getting dumber and more venomous. For instance, last week, Nadim Kobeissi (the author of Cryptocat, a competing secure messaging syst…

Oh, not at all. I've been thinking this through for some time. I don't regret it. It's rather the case that I don't think much good discussion ever comes out of Hacker News specifi…

This is Nadim (someone just pointed this link out.) Please don't upvote this. I'm not appreciating the attention, not looking for drama. Just needed to set the record straight on s…
