  • Seedless grapes already exist, but I suppose you could now insert the gene into other plants/varieties to make those seedless as well.

    I’m thinking more about how big ag companies could use this to prevent farmers from saving seeds/propagating a copyrighted variety (though I don’t know if that’s common with any crops where the seed itself isn’t the end product) or maybe more charitably, preventing their copyrighted plants from cross pollinating neighboring fields of the same species (e.g. ruining that neighbor’s non-gmo status).

    Finally, this could be useful if it can be “switched on” i.e. by deliberately polluting an invasive plant’s gene pool with this gene and then switching it on to stall the invasive’s population growth. But I think most invasives are perennials, so would still need to be removed some other way.





  • In practice, I believe the private key should contain the public key (or at least sufficient data to recover it): https://superuser.com/questions/814409/gnupg-opengpg-recovering-public-key-from-private-key#814421

    I believe you only need your private key to sign files so, technically you only need to back up the private key, but you should test this to be sure it fits your use case.

    Depending on how you’re backing things up, and what your security goals are, remember that backing up a private key may involve putting that private key on somebody else’s computer - i.e. if you use a remote git repo, or cloud backup service, or even send the key to your own (different) machine over an insecure network. Make sure that you’ve got a way of securely backing up your private key, otherwise you may undermine the whole cryptography thing anyways :).

    As always, you should test by backing up your key(s) and then testing that you can actually restore them and successfully sign a file. Backups are only as good as the last time you tested restoring from them.




  • Zigbee mostly uses 2.4Ghz, so it’s not helping remove congestion from that band anyways but I guess the other protocols do. Can’t the devices phone home as soon as they’re connected to a hub that’s internet connected? Even if the hub has to cooperate with the device, they’re made by the same manufacturers so I wouldn’t trust tleither of them.

    With wifi I can spin up a separate iot vlan that cannot access the internet. That vlan doesn’t require my ISP, it’s entirely local. I get to control exactly who connects and even who they connect with. I don’t see that same control with the alternatives.

    I guess I do see an argument for very low power devices using a lower power protocol, but I guess I just don’t have any of those devices so it hasn’t been an issue for me. And like you said traffic congestion is a valid problem, I’ve just never experienced it.
