A privacy-first website refresh

We gave nexacoreos.com a refresh that puts our money where our mouth is. The three typefaces are now vendored and served from our own origin — no request ever leaves for a font CDN, so no visitor's IP is handed to a third party. Analytics is cookieless and first-party: the measurement script and its event endpoint are served same-origin, so in your browser's dev tools you'll see requests to nexacoreos.com and nowhere else.

Under the hood: WOFF2 fonts (~68% lighter than the raw TTFs), a stricter Content-Security-Policy, proper social-share cards, a security.txt, and a press kit for journalists. An operating system built on privacy by construction should have a website to match.

Phase 1: the microkernel runs on real hardware

Phase 1 is a proof of concept you can boot on real hardware, not just an emulator. The Ring 0 microkernel is written in Rust with a frozen system-call ABI, and the operational layer — five capability-isolated system agents — is taking shape above it.

See the technology deep dive for how the pieces fit together, or the status section for what runs today versus what's still ahead.
