I've traveled worldwide promoting #FOSS & #copyleft for 30 years. > 2 million miles BIS (Butt In Seat) — 1.3mil on #Delta. But today I ponder hotels. I've stayed at 100s of hotel worldwide of all sizes — from “dives” to (very occasionally) 5⭐ — & from B&Bs to 25 floors w/2 towers. In 30 years,only *twice* could I not get 🚿 hot water (at least after 30-80 seconds). Is there some solved temp/#OfRooms/liter equation for this magic to happen all over the world? Esp. at peak 🚿⏰? #SCaLE2026 #SCaLE
