I have been working on this on the side as a hobby project. It is a Pixel Art "Resident Evil" type game taking place inside and around a pharma corporation (MediTech Pharma). The story is quite grim and the farther you go the darker it gets, even grotesque. It is about the

My new explainer with @CenDemTech covers how ECH closes one of the last major metadata gaps in HTTPS by making hostnames private. It’s been approved as an Internet Standard and is close to getting an RFC number:

Here are seven things I’m looking forward to in the next month. Tomorrow, I’ll be guest lecturing with Kyle Hogan at NYU for Sunoo Park’s class on public interest tech. The theme: bikeshedding and how to get things done in internet standards.

The Internet was built to be open and neutral. ARMOR is about protecting that founding promise by strengthening secure, end-to-end connectivity against today’s adversarial network environment.
