Gregory's Server@murks Like vacuum tube based?
I always wondered if any physical object can be considered truly digital. We can't have ones and zeroes in real world, we just consider e.g. voltage above certain level one and below that a zero, but it's not really discrete, there is noise, it fluctuates, we just don't care about that. That is why we have to use certain techniques like checksumming to make sure the information was transfered correctly from physical media.

 @m0xee @murks @safiuddinkhan things built with vacuum tubes are still digital. intentional discretization may be imperfect but it's an abstraction nonetheless. op amps are an example of analog

@m0xee @safiuddinkhan You are of course right about the abstractions that happens. I guess what I had in mind was UNIX running on a computer that does not do this discretion step.
