After looking at the multi-level replies to your original question, it
    appears that Eduardo was was not reponding to you.  I think that he was
    responding to someone (Matt K) who responded to a Spice Girls joke that
    *I* had made.

If it makes anyone feel any better, this probably left a good fraction of
the americans confused as well - at least, I had no idea what they were
talking about...

(Somehow, I don't think "The Spice Girls" are experts in computer
simulations of analog circuitry OR starship pilots...)
