The featured article implies that Fitbit is in fact being used as a black box, despite not originally having been intended so.
No it didn't. The lawyer looked at historical data of the trainer's fitbit device. It was not the last remaining record of a airliners's demise. Nor was the wearer of the fitbit... you know.... killed.
Here we go, from another news article:
The data will be provided by the plaintiff in a personal injury lawsuit in an effort to show life-affecting reduced activity post injury
Which could honestly just be the trainer not wearing the bracelet as often.
That works for the Fitbit's original intended use but not for the black box use described in the featured article.
Also, I want to point out here that the data from these devices are being used not as originally intended. Hey, it was useful for the client this time. Maybe. But you're argument here is pointing out that your data can be used to show all sorts of things. That's typically something I'd use to point out how bad of an idea it is to have a third party hold onto all this data.
Anyway, regardless of all that, it doesn't matter, someone could actually want some sort of device to act like a blackbox. Like if they were recording cops at checkpoints. I would still want that data backed up to my own computer rather than trusting "the cloud". Most specifically if I had a concern that the police might try and confiscate/lose my phone and it's recorded data.
Over the Internet? Can you seriously not connect to your computer over the Internet?
Not if your computer's Internet connection doesn't allow incoming connections, whether because of CGNAT applied by your home ISP, because of a "no servers" clause in your home ISP's terms of service,
Wow, that sucks balls. Yeah, no, if we're talking about the merits of software architectures, and which way we'd prefer things to operate, I'm going to go ahead and announce that I wouldn't purchase that service. Ever. If I got such a service, and I found I couldn't run a minecraft server, or ssh into my box, or hell, does skype work with that? Yeah, no, if I found out that's what I'd bought, I'd promptly drop it and go get something that, you know, functions.
or because it is in suspend mode to save electric power.
. . . come on dude.
