Really? There are many ways of generating PRS. There are trade-offs
with each one. If you don't need the speed or small size an LFSR has
disadvantages compared to many others.

I hesitate to get into this, err, "discussion", but in
software at least, an LFSR has one nifty advantage over the
simpler and more-common linear congruential approach: You
can run it backwards!

You can run a linear congruential backwards it's just a matter of
using different factor and addend constants.



I've never seen that. I would like to.
