  • They could make it difficult to open up the camera and extract its signing key, but only one person has to do it successfully for the entire system to be unusable.

    In theory you could have a central authority that keeps track of cameras that have had their keys used for known-fake images, but then you’re trusting that authority not to invalidate someone’s keys for doing something they disagree with, and it still wouldn’t prevent someone from buying a camera, extracting its key themselves, and making fraudulent images with a fresh, trusted key.



  • The primary reasoning I’ve heard is that it’s easier to do arithmetic with numbers that are factors of your numeral base and 12 has more factors than 10 (1, 2, 3, 4, 6, 12 vs. 1, 2, 5, 10)

    Base 12 seems a little impractical to me since humans have 10 fingers, which makes base 10 easier to teach to children, but it’s a matter of opinion i guess

    τ is equal to 2π, which allows the formula for the circumference of a circle to be written more concisely (τr vs. 2πr or πd) but complicates most other places where π is used, like in the area of a circle (τr^2/2 vs. πr^2)






  • Sometimes when I get a call from an unfamiliar number with my area code (I don’t live there anymore so it’s always a scam spoofing a nearby number) I roleplay as a 911 operator and don’t drop the act until they hang up, threaten them with penalties for wasting public resources and such. It’s probably not strictly legal but they’re calling me illegally too so i think it pretty much evens out :)










  • Personally I would rather they had to make phones a little thicker again to include a properly sealed battery compartment, the new ones look very nice but it’s too hard to get a decent grip without accidentally bumping the edge of the screen.

    Maybe the whole back side of the phone is the battery, and the two sides are independently watertight? The charger port and usb controller could be on the battery too, that way you can replace it if it breaks or you want to be compatible with a new fast charging specification, and you could charge it independently if you have more than one.




  • The pancreas is an organ which produces a hormone called insulin, which regulates the intake of sugar from the blood.

    In type 1 diabetics, the pancreas has been damaged by an autoimmune reaction, so they need to monitor their blood sugar and administer insulin to the blood using external equipment.

    This can be done manually with a needle and glucose tester for measuring blood sugar, and a syringe for administering insulin, or an insulin pump and continuous glucose monitor, which adhere to the skin and have continuous access to the blood through a cannula.

    Being able to administer insulin without a needle or cannula would eliminate a common point of failure in this system. The cannula of an insulin pump can easily become dislodged from the skin when disturbed and leak insulin onto the surface, resulting in high blood sugar and wasted insulin.
