If you have a smartphone, a car, a SatNav device, a TV, a PVR, a security camera, a power smartmeter, a smartwatch, a games console, you have nine copies of SQLite. If you have a Windows/Apple computer too, you have another four or five copies. Some of the less expected devices I have found SQLite in: * the machines in carparks (parking lots ?) which record entry/exit/payments * the hand-held devices some parking inspectors use to print tickets * a lathe which you can program with curve profiles * a hand-held gas detector used to spot leaks * the smartmeter connected to my power supply
