  • I have a wacom-type pen for a tablet that uses one of those. It was a total pain in the ass the time I was traveling and accidentally discharged it by jamming the button in a tight-packaged bag. Turns out, they are pretty much only available online. No normal shop ever stocks them, not even electronics shops nor radio shacks. Barely anyone even heard of them. Tried disassembling a few 9V’s, but all of them were the stacked kind. And with international shipping going 2-6 weeks and me changing locations more often than that, it was an extremely difficult to get hold of them.









  • No, you shouldn’t really be downloading exe’s from github. It is widely being used to spread malware and to pretend that the software is open source when it is not. At least look for a link to the store page(including microsoft store), a distro-specific package or build instructions. Those usually have an AV scan or at least harder to fake.




  • I think you are misunderstanding things or don’t know shit about cryptography. Why the fuck are y even talking about publicly unlockable encryption, this is a use case for verification like a MAC signature, not any kind of encryption.

    Calm down. I was just dumbing down public key cryptography for you

    The actual answer is just replace the sensor input to the same encryption circuits

    This will not work. The encryption circuit has to be right inside the CCD, otherwise it will be bypassed just like TPM before 2.0 - by tampering with unencrypted connection in between the sensor and the encryption chip.

    For your scheme to work, personal ownership rights would have to be severely hampered.

    You still don’t understand. It does not hamper with ownership rights or right to repair and you are free to not even use that at all. All this achieves is basically camera manufacturers signing every frame with “Yep, this was filmed with one of our cameras”. You are free to view and even edit the footage as long as you don’t care about this signature. It might not be useful for, say, a movie, but when looking for original, uncut and unedited footage, like, for example, a news report, this’ll be a godsend.


  • You must be severely misunderstanding the idea. The idea is not to encrypt it in a way that it’s only unlockable by a secret and hidden key, like DRM or cable TV does, but to do the the reverse - to encrypt it with a key that is unlockable by publicly available and widely shared key, where successful decryption acts as a proof of content authenticity. If you don’t care about authenticity, nothing is stopping you from spreading the decrypted version, so It shouldn’t affect consumers one bit. And I wouldn’t describe “Get a bunch of cameras, rip the sensors out, carefully and repeatedly strip the top layers off and scan using electron microscope until you get to the encryption circuit, repeat enough times to collect enough scans undamaged by the stripping process to then manually piece them together and trace out the entire circuit, then spend a few weeks debugging it in a simulator to work out the encryption key” as “trivial”



  • Oh, they’ve actually been developing that! Thanks for the link, I was totally unaware of C2PA thing. Looks like the ball has been very slowly rolling ever since 2019, but now that the Google is on board (they joined just a couple days ago), it might fairly soon be visible/usable by ordinary users.

    Mark my words, though, I’ll bet $100 that everyone’s going to screw it up miserably on their first couple of generations. Camera manufacturers are going to cheap out on electronics, allowing for data substitution somewhere in the pipeline. Every piece of editing software is going to be cracked at least a few times, allowing for fake edits. And production companies will most definitely leak their signing keys. Maybe even Intel/AMD could screw up again big time. But, maybe in a decade or two, given the pace, we’ll get a stable and secure enough solution to become the default, like SSL currently is.






  • I have never been on Instagram, only joined last year because apparently doing business over it’s messenger is now a norm. Subscribed to a few of my friends and was terrified. I know them, I know they’re not living like that, but the amount of effort they put into trying to appear more successful than they actually are is astounding. It’s not just showing the good things and hiding the bad ones like people on e.g. facebook do, but spending hours every day into faking it and outdoing each other. Two have actual depression and should seek help ASAP, but on Instagram they are trying to twist it in some kind of brag/motivation/skit to show how better they are than others. This is absolutely unhealthy, and I am now advising everyone to get off it and stay away for the sake of their own mental health.
