As it does every year, Google is sending users on a geeky goose chase to learn details about its upcoming I/O 2018 Developer's conference. The first clue, posted on Twitter, is a bunch of binary code that (spoiler) reveals a website address, google.com/io. That leads you to a splash screen and Google Maps, where you're positioned in front of a Google office building ready to enter into a reception area.
Update: Well, the mystery didn't last long. The conference will run May 8th-10th. In Mountain View, naturally.
