“I am announcing the formation of the Super Intelligence Force (SIF). The Super Intelligence Force is tasked with coordinating the effort of the Federal Government to ensure that America continues to lead the World in Super Intelligence, which many say is bigger than the Industrial Revolution, and the Internet, and will protect the interests, and improve the lives, of all Americans.” - President DONALD J.

Where did your email actually land - inbox or spam?

APRF is a new IETF draft: publish one DNS record, get daily placement + engagement reports by email. Like Google Postmaster Tools, but from any mailbox provider.

TLS certificate lifetimes are already down to 200 days. 100 in Mar 2027. 47 in Mar 2029.

Everyone read this as a web story. It's also an email story.

MX, MTA-STS, TLS-RPT, DANE and BIMI all sit on that clock.

And unlike the web, mail fails quietly.

A "PayPal invoice" hits your inbox.

DKIM: ✅ valid
DMARC: ✅ passed
It genuinely came from PayPal's servers.
And it's a scam. The attacker never touched PayPal.
Here's how that's possible 🧵

The fix:

Long term - DKIM2 (an IETF draft) binds each signature to its intended recipients.

Today - set a short DKIM signature expiry, so a captured message can't be replayed forever.

Developing self-discipline in the contemporary world can be an overwhelming task. Self-discipline can be built from a routine practice of journaling, mindfulness, exercise, or finding a mentor.

One of the most annoying things about Gmail is that the "View Original" option DOES NOT actually show you the original version of the email.

It shows you the HTML and plain text parts but not any other MIME parts. And it doesn't even tell you it's hiding them.
