Isn't this splitting hairs? The real achievement it seems to me is continuous operation within spec. The watchdog timers (whatever they are) are part of the design that enabled this. I don't think it lessens the achievement at all.
- okcando 7y agoSure, but it's not conventionally what is called "uptime", an uninterrupted period in a normal and responsive state. Voyager has had faults and been rebooted. In any other situation that I'm aware of, you'd have to say that uptime started over or that uptime is <100%.
- segfaultbuserr 7y ago> I don't think it lessens the achievement at all. I was not implying that "the fact that the system has been rebooted lessens the achievement", I said none of it. I was just wondering about details of the system and technical accuracy of the statement, isn't it the point of posting on HN? Running a probe for 15,364 days without even a single bit flip or poweroff would be an extraordinary miracle that exceeded all reasonable expectations, not simply the grestest accomplishment. Please don't assume that every technical statements/questions imply undervaluation, criticism or attack, regardless of how common they are in tech. Thanks.
