Some good children's book recommendations from Erik Hoel: https://www.theintrinsicperspective.com/p/books-to-stoke-the-soul-of-a-young I would add to the list Seacrow Island and Ronja by Astrid Lindgren. What are your favorite off-the-beaten-path books to read to your kids?
TIL both Intel and AMD include an additional microprocessor in their computers that has privileged access to the system: https://itsfoss.com/fact-intel-minix-case/
Nostr was mentioned on my favorite cryptography podcast today, Security, Cryptography, Whatever — they didn't spend a lot of time on it, but here are some highlights: > It’s federated and it’s European. I bet it sucks. > It’s some Ayahuasca inspired initiative from. From Messrs. Dorsey et al. > Yeah, sure, it’s decentralized and federated, but like their proposal for encrypted end to end encrypted DMs was just bad by itself. > When I reviewed this, my description of this was it looks almost exactly like Nebuchadnezzar [ https://nebuchadnezzar-megolm.github.io/] , which is like a fractal of things that could have gone wrong with like a complete ecosystem of like a secure messaging system. They found flaws in almost every component of that system and then tried to leverage them as far as they could. You can read/listen here: https://securitycryptographywhatever.com/2025/07/29/vegas-baby/ They also mentioned a talk that's going to be delivered at blackhat on August 9th which sounds super interesting: > In this session, we unveil the first comprehensive security study of Nostr and its popular client applications, demonstrating how subtle flaws in cryptographic design, event verification, and link previews allow an attacker to forge "encrypted" direct messages (DMs), impersonate user profiles, and even leak the confidential message from "encrypted" DMs. Here's the link to the agenda entry for the talk: https://www.blackhat.com/us-25/briefings/schedule/#not-sealed-practical-attacks-on-nostr-a-decentralized-censorship-resistant-protocol-45726 I'm looking forward to learning how we've screwed up — there aren't a lot of cryptographers here, and I know that open protocols make security even harder to maintain. Maybe we've screwed up irretrievably, but I'd rather know now than later.
