Real-time messaging
A dumb pet peeve I have is the use of the term "real time".<p>What on earth do you even mean by that?<p>Talk to a controls engineer about real time operating systems and PLC programming, and you get a very solid definition. Talk to a software developer and it means something like "as fast as we can, without any purposeful delays or buffers".<p>Maybe I'm just a pedant, but the entire article has graphs with no numbers, no defined service level objectives, and vaguely mentions 500ms at the end.<p>What is real time?
