In Italy I saw a replication of Fra Angelico's Annunciation as a sculpted relief intended for the blind.

if you work from home, a sticky note with a strong password might be safer than a memorized employee-chosen password

"Just" is used in chess commentary frequently and usually a bit too flippantly as the speaker hasn't gone through all the necessary calculations as the players have to. Sam Shankla…

I haven't used this for large deployments but I use it for my personal server and it works perfectly. Almost everything is built in and I can easily write my own custom operations …

Having played around with Clojure and Scheme for a while (but never got too serious), I always thought homoiconicity and macros were extremely cool concepts, but I never actually r…

I think both the idea and execution are great. These games would be useful even just as problem statements. I like that each problem clearly defines the desired tone and goals, and…

Yes, that's exactly what we both agreed on 6 comments ago. The question is, is the ability to delete messages critical enough to require in any possible secure messaging solution, …

>The premise of cryptographically secure messaging is that you have an adversary recording all your message traffic. Agreed. >Lack of forward secrecy implies, logically, that if yo…

Your argument is that forward secrecy is important in messaging because forward secrecy is important in messaging? I'm not trying to be argumentative here, I actually don't underst…

I agree with you there. But is your point that any secure email system must critically have forward secrecy, or its insecure? Even though forward secrecy really only gives you any …

But this only applies for messages that are deleted on your local device (either manually or through an automatic timer). Otherwise, whatever adversary stole your keys can steal yo…

Assuming you don't want to keep any "chain state" in between messages (which seems reasonable), you can always consume a fresh one-time key of the recipient for every message. The …

There's this old picture from a 1986 MIT lecture: https://miro.medium.com/max/4448/1*-yaqXNO1tUwVkUpyOqTT7Q@2x... .

I don't think people want forward secrecy for their email. If they get a new computer, they probably want all their mail on there, right? Isn't porting over their email efficiently…

Thanks for the reference. Haven't looked into this in a few years, cool to see something has shown up about it now. I guess Sweedler was just having some fun then? Still curious ab…

When doing some research for a final project about using Grobner bases for cryptography, I came across an interesting paper titled aptly titled "Why You Cannot Even Hope To Use Gro…
