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
Yeah, it used to be just web servers in a data center. Bigger systems used mainframes. Consumer electronics used custom RTOSes or other custom boards. Now it’s everywhere. It’s used in the biggest systems, like the computers that power virtually every Google product, and the smallest systems. It’s almost not worth it not to use Linux when building a tiny device because it makes the dev cycle so much shorter.
