[sdiy] power rail decoupling?

[Matthias.Herrmann at jeppesen.com]

both the positive and the negative voltages from the supply go right 
through a bead (or a 10-20R resistor) to the circuit. the positive and the 
negative rails then are connected to ground via the caps. the ken stone 
circuits sometimes show caps and/or polarized caps. 

you won't necessarily have to decouple the circuits on the breadboard. i 
never did yet but i think it would be a kind of good practice.
