Hello all,
Can anyone advise on the theoretical basis for the
unpredictableSeed method in std.random? I've tried googling
around for the theory of good thread-safe seed generation
methods but haven't really found anything. :-(
Thanks & best wishes,

You can use the real time clock, which should have nanosecond
precision. It should be very hard to predict because the clock
will fluctuate based on environmental factors. I don't know if
all architectures have an adequate real time clock however if
portability is needed.

Maybe you can try to connect an external hardware device (e.g.
arduino) and read some params from real world... :)
