    Understanding Polycystic Ovary Syndrome (Now Officially Renamed PMOS), Getting a Real Diagnosis, and What Actually Helps

    You were told it was stress. Then that you just needed to lose weight. Then you got a prescription for birth control that masked the symptoms without explaining anything, and a name - polycystic ovary syndrome - that never quite fit what you were actually experiencing: exhaustion, skin and hair changes, a body that didn't respond to effort the way everyone said it should. In 2026, the condition ... Leer más

  • Computer Vision with Python and OpenCV

    Database Administration and Decision-Making for the Era When "Just Use Postgres" Won

    'Just use Postgres' used to be a slightly contrarian opinion. Now OpenAI is on record describing how it serves 800 million ChatGPT users off a single Postgres database, and the r/Database and r/PostgreSQL communities are openly debating not whether Postgres won, but what's left for a specialized Oracle or MongoDB deployment to justify itself. The DBA career track built around specializing in one ... Leer más
