Exposed: inside the intelligence agency's briefing room, where secrets black out mid-sentence

In plain terms. Like a shared Google Doc where some words are classified. People without clearance see black bars, and a manager can take away someone's access while they're typing.

Under the hood. NestJS and Yjs over PostgreSQL row-level security. Hidden text never leaves the server, and open connections are re-authorized before a permission change commits. 600+ tests.

Leak-proof: the messaging app built on the assumption that its own server is already compromised

In plain terms. Private messaging where even whoever runs the server can't read your messages or quietly change them.

Under the hood. Encryption in the browser with libsodium, signed hash-chained history, and a key transparency log with Merkle proofs.

Lighthouse · Infrastructure · The system behind this page

The website that monitors itself, logs its own failures and publishes the evidence

In plain terms. A system that keeps watch over every project, notices when one goes down, records an incident and publishes what happened. It also checks a demo is up before opening it for you.

Under the hood. Go and PostgreSQL with row-level security, SSRF-safe probes, incidents opened by a state machine, property tests and fuzzing. Runs free on Cloud Run behind a Cloudflare edge, deployed without stored credentials.

Off the grid: how a laptop and a tablet share files without ever touching the cloud

In plain terms. A Linux PC shows up in every Android file picker, like Google Drive, but the files never leave your own network.

Under the hood. A FastAPI server on the PC and a native Android DocumentsProvider, built around one rule: the tablet only opens outbound connections.
