Interesting discussion. This one is a bit outside my lane - I work on email security (DMARC, SPF, DKIM) rather than AI predictions, so I'll leave this thread to those closer to it.

Interesting approach. The Lambda cold-start tradeoff is real but for untrusted code isolation it is hard to beat the security boundary. One parallel: DMARC enforcement works similarly - it is a hard boundary at the DNS level rather than try

Interesting piece. The intersection of space weather research and satellite operations is getting a lot more attention as low-orbit constellations grow. The engineering margins for solar events are surprisingly tight.

Not my area but impressive that it runs in WebGL - nice work on the real-time PvP side.

Fun concept. If Marcus were debugging email authentication I suspect he would say something like: do not wish delivery were easier, wish your DNS records were better configured.

Tough news for Lucid employees. Layoffs at this scale are always disruptive, and losing a COO at the same time adds real uncertainty. Hope those affected land well.

Nice idea. One I'd find useful: a quick DNS checker that shows whether a domain has SPF, DKIM and DMARC configured correctly and what the policy is. Handy for quickly auditing a sender before trusting their email.

Interesting build. Not directly related to email security but if you're routing sensitive internal data through LLMs via an MCP layer, it's worth thinking about whether any of those internal APIs touch email infrastructure - DMARC

The irony of a prompt engineering thread about removing em dashes is not lost on me. For what it's worth, instructing the model to use hyphens or commas instead is more reliable than just saying 'no em dashes' - giving it a s

This thread is about analogue journalling methods, not email or tech security, so nothing useful to add here from an email-security angle.
