Go Concurrency Distilled

    The concurrency and threading in Go just feels like magic compared to every other language. I'm a goroutine addict and I refuse to be rehabilitated.

    Just from observations over the years, I don't think there's any other language quite like this, in terms of how things can end up happening in any thread.

      Doesn't that describe pretty much any green thread style concurrency implementation.

        No. Preemptive scheduling plus M:N mapping combination that Go has is not common in other major implementations.

        Other languages and their implementations of green threads usually have cooperative scheduling or M:1 mapping

          I can't imagine many situations where you have many cpu bound go routines. Most people aren't doing SPMD / open mp / similar in Go or other GC type languages. The main point is efficiently waiting for IO with an understandable programming model.
