Here’s a few that I know of. What other things are commonly running Linux that most people may but be aware of?
- Ingenuity (helicopter drone on Mars)
- Smart TVs and streaming devices (Samsung’s TizenOS and Roku devices)
- Smart appliances (Samsung’s smart refrigerator)
- Digital signs and billboards
- My car stereo (Sony XAV-AX6000)
- The Large Hadron Collider
- FAA Air traffic control and radar systems
- Self driving cars
Pretty much everything that’s running on a microprocessor (i.e. larger than a microcontroller) and not from Microsoft or Apple.
