·1 views

A bit of terminal trivia for your next coffee break. All five are true, I promise. Before grep existed, you'd search a file in the ed editor with: g/re/p global · regular expression · print. Ken Thompson turned that one command into its own program, and the name stuck. $ date -u -d @2147483647 Tue Jan 19 03:14:07 UTC 2038 2147483647 is the biggest number a signed 32-bit integer can hold.

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Tap 📍 Use my location. You get the best 2-hour window before sunset (scored from the hourly forecast), real parks, gardens, trails and viewpoints nearby on a map, and a short plan with a mini mission ("spot a crow and three kinds of leaves").
