  • android uses digital signatures as kind of a security measure. a digital signature is basically supposed to confirm that the apk was actually built by the developer, and most of the files in it were not tampered with.
    besides being able to make permissions depend on it, you cannot install an app update that was signed with a different key to what you have already installed, because that basically means you are replacing it with a version that was built by someone else.

    all apps are digitally signed. when an app becomes reproducibly built, from that point the app will be built by f-droid with their own digital signature.

    also note that since google play has forced all developers to hand over their signing keys, when making app bundle based publishing mandatory, the security of this signature has been… less useful







  • i still don’t understand. is it easier in python or JS to make getters and setters? with python my experience has been the opposite, with the decorator based solution in mind.
    or if the problem is that they exist, as an option to be used, why is that a problem? they can be implemented in any other language, and it can be useful.

    then yeah, you should check for nulls. just like for None’s in python, or if you have the correct type at all, because if it’s entirely different but ends up having a function or variable with the same name then who knows what happens.
    then in javascript besides null, you also have undefined and NaN!
