🛰️ How GPS works
-
An article that starts by showing you the raw data your phone receives from satellite. Plot twist: it does NOT include a position! It just includes time.
-
I want to walk through exactly how you can find your location from these raw GPS signals, by hand if possible, without dumbing it down.
-
Most people are not aware that GPS (1) can work without internet access, or cell towers, or any kind of large terrestial infrastructure (2) it's controlled by specific countries, and they can choose to turn it off (and it has happened)

❄️ Snow Yourself
-
You play as a pile of snow, you can reshape yourself to solve puzzles & explore the world
-
It's also an exploration of questions about consciousness like, if you replace every cell in your body, are you still you? If you split in half, which part is "you"? What does it feel like to have multiple "you"'s? How does an octopus feel with a distributed brain? etc
