The Day GPS Went Public: Midnight Without the Blur

Late on May 1, 2000 (UTC May 2), the U.S. government turned off Selective Availability (SA)—the intentional signal distortion that kept civilian GPS readings fuzzy. Overnight, backyard receivers tightened from ~100 meters to ~10. What changed wasn’t the satellites in orbit but the policy governing their signals. That one decision unlocked consumer navigation, geocaching, app‑based mapping, precision farming, and global logistics at scale. (more…)

Why Door Handles Are Brass: Hygiene Before UX

Before “user experience” became a product discipline, buildings made quiet design decisions in the name of public health. The humble brass door handle is one of them. Hospitals, schools, and civic buildings installed copper‑alloy hardware not for prestige but for a simple promise: it might stay cleaner, longer, between cleanings. That logic traveled from 19th‑century germ theory debates to 20th‑century building codes, and eventually into the ordinary places where we spend our days. The gold tone is a side effect of a material that balances machinability, durability, and a reputation for hygiene. (more…)
