  • To give a bit of technical details, the hardware must have a feature to destroy encryption keys for user data whenever a new OS is installed on it; and you have to be able to install a new OS on it at all.

    Like, today, many smartphones have the problem that you can’t install a new OS on them at all, because the bootloader doesn’t allow it. Meanwhile PCs have a different problem, where they do allow installing new OS, but the user data is typically not encrypted and so you can just boot linux from a USB device and read all contents on the internal disk.

    The best solution might be to encrypt all userdata, store the keys in the bootloader on the device, but when a new OS is loaded/installed, the bootloader doesn’t give out the keys so the userdata can’t be decrypted.











  • yeah it’s really really fragile. they show it in the video, one of the panels broke because a cat stepped on it. obviously not very suited for real-world deployment.

    however i do wonder why they use polycrystalline silicon and not just amorphous silicon? I mean 20% efficiency instead of 8% makes a difference but i did some rough maths and it could still work with amorphous silicon if you use the area on the drone better. But amorphous silicon has the advantage of making a very thin and flexible layer that doesn’t break easily. It’s essentially more like a flexible piece of cloth instead of a solid object. Maybe worth a consideration.







  • yeah having the bread be mold-resistant is obviously kinda important. i wonder why it doesn’t spoil immediately when it’s laying around when it’s moist. idk i’m only guessing here but might it have to do with the baking process adding a kind of “coating” layer of dust around the bread? Like, we smoke meat to make it durable for a year, might be the baking doing something similar to the bread?
