Instead of just downvoting, how about refuting my claim? I'm seriously curious what is the disagreement. These guys already established atomic clocks are unnecessary. Very interested in which use cases require them.

Read and learn: https://research.google.com/archive/spanner.html https://research.google.com/archive/spanner.html Serializability is all about ensuring a single consistent ordering of events. Lots of algorithmic shortcuts you can take if all your nodes' clocks are precisely in sync.

  I'm very familiar with the literature since I'm a distributed database developer. If you investigate high frequency trading you will understand that the quantum phenomena that I'm talking about is not just me high on mushrooms but a real world thing. The only "time" relevant is the time when the cluster agrees an atomic, isolated transaction is time to commit from its own perspective.

Am I wrong in remembering that the HN guidelines used to say that you should not downvote someone's comment simply because you disagreed with it? I went looking, and I don't see that in the current guidelines. I could be wrong about it being there before, but I was almost certain that it was at one point. Seems like it used to say that you should only downvote comments that you think don't contribute anything of value to the conversation. Just curious, because it seems to me that for quite a while now there have been a lot of comments that appear to get downvoted just because people don't agree with what the person said (and often there are no responses to counter, the person just gets downvoted).

  I think you're thinking of somewhere else. The up/down votes are a way of agreeing or disagreeing without cluttering up the comments with a bunch of "me toos" or "nuhuhhs"

    I'm certain that I'm not thinking of somewhere else. I'm completely open to the possibility that I just remember it wrong, but I'm sure that it was HN that I was thinking of, and not another site.

      You're thinking of Reddit.

        Reddit, we did it again.

        No, you did not "do it again". I almost never read anything on Reddit. So that was not the source of confusion.

        Nope, I know I'm not thinking of Reddit (as I said in reply to another comment, I've spent almost no time on Reddit, and would not have seen their guidelines at all).
