  • Step away from hardware constraints for a moment, and consider the OS:

    If the OS says a file is deleted, under no circumstances should the OS be able to recover it. Sure, certain tools may exist to pull it back; but it should be unavailable to the OS after that. And yet, apparently a software update was enough to recover these files. Thus, the concerns about data safety in an environment where the OS cannot be trusted to remove data when it says it has been removed.











  • Yep, airships aren’t overpressurized like a balloon - any leak will be extremely slow, as the heavier ambient air gradually displaces the helium inside the airship through whatever hole might be created. As I understand it, one of the big maintenance issues they have is even finding the holes from normal wear and tear. The usual failure scenarios involve storms with huge pressure changes.







  • As a 41 year old, when I call someone in their early-mid 20s a kid, there’s no derision intended. Think about how you relate to someone who’s 12 or 16 when you’re 20 or so - they might be quite capable, even fun to hang out with; but their life experiences also give them a clearly different outlook. And, like as not, you feel a little more interest in making sure they’re getting along all right (at least I do!)

    As you age, that doesn’t really change - but the “target age” where that comes into play follows you up! So at 26, you feel that way about people just coming into high school; at 30-35, about people getting out of college and starting their careers. My oldest kid is 6; and I feel this way now about most of the parents of my kids’ classmates! Makes for a fun juxtaposition, when they have older kids and know more about what we’re in for than I do :p

    It can turn into something condescending, depending on the person; but I think it’s usually more of a statement that “I remember being where you were!”
