Photo-Based Calorie Tracking Is a Lie. Here’s the Unsolved Physics Problem.

Photo-based calorie tracking apps promise effortless dietary logging, but they are built on a fundamental physics flaw. A 2D image cannot capture hidden caloric densities like oil or dressing. By replacing educated guesses with a confident illusion of precision, these apps don’t solve portion estimation—they just mask it with fake math.

Why Your Phone’s Scanner Is Lying to You (And the 9-Year Fix That Changes Everything)

You’ve spent more time than you’d like straightening crooked document photos. Most scanners fail on real-world conditions — crumpled receipts, glossy pages, whiteboard glare. After nine years of development, Perspec 1.0 solves the hidden geometry problem of automatic corner detection, turning a frustrating manual tweak into a single click. It’s a quiet revolution in productivity that reveals how much we’ve been settling for broken workflows.

This Solo Hacker Built a Pool Training System That Will Make Human Referees Obsolete

A solo developer spent months training a custom computer vision model to build a pool training system that projects perfect aiming lines onto the felt. The technology is a stark example of how accessible AI toolkits now allow individuals to create augmented reality tools that once required corporate R&D budgets—and it hints at a future where human referees and subjective coaching become obsolete.
