Treasure Troves and Portable Companies

A friend of mine is dealing with cancer. When I started building CureCancerMagic - a care coordination app for exactly this situation - I noticed something about how information flows during treatment. Doctors send referrals. Friends text you articles. Your cousin emails a link to a specialist in another city. All of it is valuable. Almost all of it gets lost.

There is no path from a Raspberry Pi’s micro-HDMI output to a Studio Display input. The solution, I thought, was going headless - SSH from the Mac on the same network. But the Pi I bought had all the ports locked down in the configuration, so SSH wasn’t an option either.

Forty-Three Tickets and a Cancer App

I was staring at the CureCancerMagic care team invite system when I realized this was the ninth ticket in a row for an app that didn’t exist last week. Care team invites, email ingestion, AI-powered summarization, document management, notifications, reporting, mobile optimization, multi-case support. By the time I shipped the last fix - a migration that almost overwrote PostgREST’s schema list - the app was real. That was maybe a third of the day. ...
