    Seems novel. But from a security aspect, if OpenSSH has security vulnerability that allows an unauthenticated user to login, via whatever means, once you are in the system as a non-privileged user, you are now free to use the same vulnerability to get root.

    Basically this exercise is like using two locks that have the same key to open them. If the same key opens them, then a weakness in one, is now a weakness in the other so why bother with two identical locks?

    hahaah. Ok sure you win. Linux TTY’s are absolutely not terminals. Sure they are called terminals, they are for all intents and purposes modern-day terminals with a long and storied history that directly links them to terminals from the 70’s but since they aren’t a physical piece of hardware that electro-mechanically connects to a mainframe, obviously they aren’t really terminals and they should be be called something else.









  • The length of time an empire existed isn’t really important in the study of history. You need to describe the contextual existence of the empire within history, and you do that by specifying the start and end dates (in whatever calendar system you want to use). Using your example, if you say that empire existed for 101 years, why is that significant? It’s not. But if I say that empire existed in the middle east during the time of Christ and Roman occupation of Palestine, THAT provides the important historical context for why that empire was significant, and what kind of importance it may have had.

    But you are missing the point,. There is no reason to ever start a calendar at year zero. The starting point can be zero, fine, but once the first day goes by, you are in the first day of year 1, not year zero and that is logical and has nothing to do with smart astronomers etc, “not understanding the number zero.”

    At this point I’d say the only person who doesn’t understand zero is you.

    “They,” i.e. the catholic church, or whoever was tasked with coming up with a calendar, absolutely understood the concept of zero in the 1500’s. Yes, Zero took a bit longer to formalize and enter the zeitgeist of the public consciousness, but this myth of zero being some kind of unknowable thing for thousands of millennia is naive.

    I’d go so far as to say that a year zero in a calendar is useless. There should be a starting point of course, but calling it yero zero instead of year 1 is dumb.
