    The Europeans have already cooperated with Americans so that each could read each other's citizens' private messaging which would be illegal for the locals. Keeping the data overse…

    Python has LiteralString for this exact purpose. It's only on the type checker level, but type checking should be part of most modern Python workflows anyway. I've seen DB librarie…

    Generally, yes: https://reproducible-builds.org/docs/timestamps/ Since the build is reproducible, it should not matter when it was built. If you want to trace a build back to its s…

    This is a Gmail-specific feature. I'd guess it's there for user convenience and some protection against typos (accidental or malicious). https://support.google.com/mail/answer/7436…
