- henrik_w 9y agoI've used the same technique when running randomly generated traffic when testing telecom systems. Very useful to be able to re-run the same random sequence!
- IanCal 9y agoYep, this is a really useful approach, and I highly recommend anyone here who is thinking of trying this stuff out to take a note of the seed (or ensure it's printed) as the first time you realise you want to do this it's often too late!
