🤖 Prove this photo is real

Roc Camera

AI has blurred the line. Now, how we take, share, and create images has changed. Social media has made sharing images easy. Generative AI now creates any image we can imagine…By combining attested sensor data, zero-knowledge proofs, and a tamper-proof environment, we've built Roc Camera to capture verifiably real photos.

This is a technical solution for what I think is more of a social and cultural problem. It suggests a dystopian future where any form of media is assumed to be fake unless it is verified. I hope that trust and accountability can remain at the center of our social contract, but tools like this may find a place in certain contexts.

A system to organize your life

Johnny.Decimal

Johnny.Decimal is designed to help you find things quickly, with more confidence, and less stress. You assign a unique ID to everything in your life. These IDs help you stay organised. They impose constraints that make it harder to get lost. And you create your own index to link everything in your life together. The system is free to use and the concepts are the same at home, work, or that club you manage.

I've followed this project for many years. I was immediately drawn to the sheer ambition to organize everything, helping you “find things quickly, with more confidence, and less stress.” The system is robust, walks you through every step, and addresses every scenario. There seems to be a rich community to support your journey. The site itself is beautifully rendered, bolstered by the irresistibly exacting typeface Berkeley Mono.

A few days ago, the proprietor made the workbook free. Check it out if you've ever felt stressed about losing track of something in your life.
