- Udo 13y agoI'm not sure you actually meant it as a joke, but that's hilarious in a cynically-detached kind of way. So these machines are not bought but licensed and they will fail as soon as the manufacturer becomes unable to continually grant usage rights, i.e. during a region-wide catastrophe.
- superuser2 13y agoI'm merely pointing out that GPS outage would be no more than an annoyance. . If the machinery experiences significant acceleration in an earthquake, it's not necessarily intact or safe to operate afterwards. The enclosing machine shop is also not likely to be in any state to continue operations if something as large as the pictured CNC machine has been thrown across the room. I don't buy that this issue is a big deal either. From a software freedom standpoint, yes, this is terrible. But I don't think it's as much of a problem for the owner as the parent suggests.
- yaddayadda 13y agoI have no idea how many of these machines are in a given area, but assuming it is an IMU [1] triggered lockdown, an earthquake could lock down many (10?, 100?, 1,000?) in a single geographic area very, very quickly. That seems like a big problem. If the lockdown mechanism is GPS, then it should be clear where the actual machine is, so there shouldn't be any need to lock it down unless it's in a black zone. And what happens if the manufacturer goes belly-up? [1] https://en.wikipedia.org/wiki/Inertial_measurement_unit https://en.wikipedia.org/wiki/Inertial_measurement_unit
