  • The article doesn’t make it clear (it could be better written) but my guess is that the card was actually found intact in the wreckage that they recovered back when the sub went down.

    The various documentaries by Netflix, Nat Geo, etc. only came out a few months ago as the USCG investigation wrapped up. Those revealed new details, like that they had recovered personal belongings from the pockets of one or two of the victims. I don’t think those details were publicly known (or at least reported on) until the documentaries came out. This is likely just a similar case of more evidence coming to light.


  • My wife has a dog boarding business, and a good number of the dogs have air tags attached to their collars. Most of the owners geofence around our home/boarding facility so that we don’t get constantly nagged by them. But when we drive one of these dogs somewhere (usually to walk/exercise them on a hiking trail etc) we often get alerts on our iPhones about unrecognized air tags that have been nearby us for a prolonged time. It will include a map showing our track and where/when the air tag was detected each time along the way.

    So while I don’t use them personally I’ve seen that they do indeed work quite well. Maybe next time I travel I’ll get one for my luggage.




  • Biometrics are not usernames. They are physical identifiers and unlike usernames you can’t change them.

    I used to work in a datacenter that required you to go through a mantrap to access. It required three things:

    1. Something you have (a card key)
    2. Something you know (a PIN)
    3. Something you are (biometrics)

    To get to the datacenter floor you use a card key to open the door to the mantrap. It’s a small vestibule about the size of a phone booth. Once inside the door closes. You then enter your PIN on a keypad and place your hand on a biometric scanner. Once your hand is recognized the inner door opens and lets you into the datacenter. I was told the mantrap also weighed you and compared that with previous trips through to make sure somebody else didn’t sneak through with you.




  • Lots of people forget that Tesla is much more than cars at this point. Musk now claims it’s an AI company, but aside from that vaporware they also build & sell utility grade battery storage systems for electric grids, Powerwall batteries for home solar systems, vehicle insurance for the cars they sell, etc. They also run virtual power plants for electric utilities that consist of Powerwall owners who opt-in to the program and are paid a premium for the power they supply. Just a month or so ago they tested a VPP in California that consisted of 100,000 individual PowerWalls.

    And then there’s their attempt at robotics…
