  • Ok, I’m still not clear on exactly what you’re trying to achieve as I can’t quite see the connection between somehow preventing certain files being duplicated when cloning the disk and preventing yourself from reinstalling the system.

    Bear in mind that reinstalling the system would replace all of the OS, so there’s no way to leave counter-measures there, and the disk itself can’t do anything to your data, even if it could detect a clone operation.

    If what you’re trying to protect against is someone who knows everything you do accessing your data, you could look to use TPM to store the encryption key for your FDE. That way you don’t know the password, it’s stored encrypted with a secret key that is, in turn, stored and protected by your CPU. That way a disk clone couldn’t be used on any hardware except your specific machine.


  • Nothing can prevent a disk clone cloning the data, and there’s no way to make something happen when a disk is cloned as you’re not in control of the process.

    If you wish to mask the existence of the files, use either full disk encryption, in which case cloning the disk doesn’t reveal the existence of the files without the decrypt password, or use a file based encrypted partition such as veracrypt in which case the cloner would just see a single encrypted blob rather than your file names.

    Ultimately encrypting the files with gpg means they have already effectively ‘destroyed or corrupted’ themselves when cloned. If you don’t want to reveal the filenames, just call them something else.

    If you could be a bit more specific about your threat model people may have better ideas to help.


  • I don’t think that’ll do it. The propellant deflagration is so quick that the momentum of the drone means it can’t be accelerated backwards enough to significantly reduce the force on the airframe. Even if it did, that would just end up applying the acceleration to the internals such as the batteries and motors/engine instead. I think you would need a spring damper that would allow the weapon to recoil quickly and dissipate the energy more slowly, and I’m not sure you could make obe effective on something the size of a drone.


  • I was thinking about those, but I understand they tend to suffer from inaccuracy due to even slight imperfections in the manufacturing of the jet openings.

    I think something more like a conventional round, with a heavier casing and more propellant might work. The casing gets ejected backwards and the projectile forwards, without imparting momentum to the barrel. You do need more propellant to get the same muzzle velocity though.


  • I’d imagine the shock loading into the drone’s structure would soon damage it if it was powerful enough to flip it. You’d need a significant damper to spread the shock out over a longer period. Alternatives are either recoilless rifles as suggested or something more akin to rockets, basically a tube that’s open at both ends, with a round that has enough propellant to fire without the need for a breech, and electronic ignition.

    I don’t think foxes typically go for cats around here, and, as far as I’m aware, not much eats them either. We don’t have any of the larger predators that might kill them just to remove competition either, so I suppose foxes are apex predators here too.

    On the other hand, I can see either a cat or a fox being a tasty morsel for a bear, so tge whole apex/meso distinction is certainly location dependent.

    I think that might be geographic dependent, for instance there’s nothing around here that would predate cats, which would suggest they are, locally at least, apex by default.

    There aren’t many wildcats left here though, maybe if there were we’d see larger predators move in and push cats down the food chain, so I can see the mesopredator argument.





  • What was the purpose of that action? To seed shock and “ruffle some feathers”, sow disbalance under the coat of “shaking sleeping people up”.

    A goal at which it has singularly failed. There’ll be a bit of noise in the papers for a day or two, Stonehenge will be cleaned off with “No harm done” and life will move on with no useful change.

    Their stunts were effective the first time or two, but now are largely ignored or even just cause irritation.

    If they, indeed we, want to change the trajectory of human caused climate damage we need to build bridges at the community level and bring people together to force the hand of the political class. These stunts don’t do that, they just give ammunition to those who seek to prevent positive change.


  • This is an approach to life sentences I’ve considered before; I would suggest the prisoner could only petition for execution after being incarcerated for a significant period (20 years or so maybe?) and having exhausted all possible legal appeals. The delay is there to ensure it’s not a decision taken in desperation and haste. By that point, if any new evidence to exonerate them is going to turn up, it probably has, although I acknowledge that’s not always the case.

    I’m not sure I’d equate it to voluntary euthenasia as the prisoner isn’t leaving jail alive either way. On the other hand, I can see why linking the two makes sense too.




  • I don’t know about the shrooms, my reading of the old testament made me think it started with some old guy trying to stop his nomadic desert tribe dying of anything too stupid by telling camp fire stories with some sort of message. The whole ‘god will make the ground open up to swallow you and your family if you screw up’ is a desperate attempt to scare them into not doing stupid things like slaughtering too many of their livestock at once, or eating shellfish whilst wandering around in a desert. The stories get retold, changed and embellished over generations before being written down, and you end up with the weird mess of basic survival tips, animal husbandry, heroic stories and mystic fluff that is the OT.

    The new testament is just the story of a fairly chill guy, with a slight messianic complex, wandering around with his mates and suggesting people be nice to each other, put through a similar transformation.
