  • For IOS devices, by default has “fixed” randomized MAC per network, i.e. each Wireless network you join sees a different MAC, but they’ll stay the same even if you leave and re-join (or even delete and re-add). So, it should not hamper MAC filtering since your AP will see the same MAC from the same device, unless you’re running more elaborate setups like multiple APs (I don’t know how IOS treats that).

    This can be changed on a per-network basis in any case, so it is possible to turn it off on the device just for your home network.




  • Need to input an additional passcode which is unnecessary when using a cash card, and still need to input the PIN. It is remembering 1 more thing in exchange of carrying the card.

    Not as insecure as I first thought as just scanning your face and getting authenticated, nor as convenient as that would be.

    I don’t see it getting so popular that it replaces cash cards. There is not a huge advantage to the user so banks probably cannot convince that many people to give up their biometric data for this service.




















  • Disclaimer: this is not from experience so perhaps someone who do run servers with USB HDDs can comment on long term stability of USB as an interface.

    Technically speaking, even USB 3 gen 1 (5Gb/s (gigabits per sec)) is far more than enough to saturate a broadband connection (probably under 1Gb/s). Assuming you’re going to use mechanical HDDs, best case they can transfer around 200MB/s (that’s megabytes per sec)), so no problem there either.

    You might want to use external 3.5 inch HDDs as they have separate power supplies (less picky on power supplied from USB) and are much more likely to be CMR (which performs better than SMR, best if you check the specific model’s spec to make sure it is CMR) than 2.5 inch ones.
