  • They occupy a strange niche full of contradictions.

    Entering the code on the device itself should increase security as opposed to entering it on a compromised computer.

    But plugging it into a compromised computer means the data is compromised anyway.

    Their security is way harder to audit than a software solution like PGP. The actual “encryption” varies from actual decent setups to “entering the code connects the data pins with no actual encryption on the storage chip”

    Not having to instal/use software to use them means they are suitable for non-technical users which in turn means more support calls for “I forgot the pin, it wiped itself, can you restore my data”

    They are kind of useful to check the “data is transported on encrypted media” box for compliance reasons without having to manage something bigger.













  • Well I doubt this can match the supersports acceleration ;) but I get what you mean.

    It’s actually interesting from a design standpoint. How do you handle a lead vehicle that has much better acceleration. Do you artificially slow down the lead vehicle so it can’t abandon the “towed” trailer? What does the follower do when it loses the leader. This basically needs nearly fully autonomous driving.


  • Eh, even If it does, it shouldn’t be a problem. Relying on a wireless link that could fail due to interference or jamming for actual control would be Musk-level insane.

    The hitchbot would need to be capable of visually following the lead vehicle, possibly using something like a big QR code for identification and tracking.

    The wireless link could be for telemetry like range and non-critical controls like “stay here” and “start following”.

    If the link fails, you get a big warning to stop ASAP but the bot keeps following.


  • The good thing is that you don’t need to know which ports to block. You just set your firewall up to deny by default and then start whitelisting the things you want to allow.

    Even easier if you put your “smart” devices in a separate network, then it’s just:

    • Allow traffic from home net to Internet
    • allow traffic from home net to iot-net
    • drop the rest

    Now you can surf the internet, control your devices and they can’t phone home
