  • Ah a fellow perun addict.

    Honestly I think he oversold the effectiveness of the systems. The work I did is still ongoing so I’m up to speed on the available systems, though mostly on the RF side. If you watch the stuff coming out of Ukraine the drones aren’t really being impeded all that much and if you know how to use ardupilot and selectively enable your data link you can pretty much get away with whatever you want because the US isn’t gonna allow anyone to jam GPS right next to multiple major airports. If you want to avoid even relying on GPS there are starting to be mature solutions out there too.








  • Yeah the FPV community is way better because they actually have to know what they’re doing mostly. They’re mildly noncompliant but only regarding the regs that shouldn’t apply to the size of stuff they fly; RID, registration, and BVLOS don’t make sense for airframes lighter than a goose. They tend to avoid other people because they understand the public is wary of drones and they’re wary of Karens and untrained cops. They put far more hours on their airframes than any of the other amateur operators but every single time I’ve been near a drone doing something dangerous, stupid, or annoying it was a DJI.





  • I used to do some work with Qualcomm and ARM IP. They both need to die. ARM is holding back all manner of technologies with their absolutely insane and byzantine licensing scheme and Qualcomm is one of the most evil tech companies in existence, you just don’t hear about them because their particular evil is constrained to B2B interactions.






  • Did you read the article? There were a couple cases were very early Android phones were modified to appear to be off but stayed on. This is fairly common knowledge, but it’s not particularly hard to defeat.

    Everything your phone does requires a deterministic amount of power. Spying on people in particular requires even more power than normal because you need to run the power hungry gps in addition to the modem and cpu.

    If you turn off the device it should be significantly cooler to the touch, not a degree above ambient. If it’s at 100% charge but a power bank with a read out is showing it still charging, that’s a problem. Is the bootloader image different? You can verify that to some extent. When you turn it back on has it been drawing down the battery anyway? Does it require an unlock password instead of biometrics as it normally would (assuming a particularly sloppy setup)?

    This isn’t rocket surgery, in reality nobody is modding everyone’s phone to stay on forever because unless you’re an absolute troglodyte (aka the fucking old school mafia bosses they did this to) it’s going to be painfully obvious your phone is acting weird.
