If you are driving something that really should not be a transmission line for your application from fast enough driver that makes it look like a transmission line then source termination (or just placing random resistor there as who the hell knows what the characteristic impedance of the thing really is) is the main thing that everybody should get from Handbook of Black Magic. Ferrite beads are for when you are driving external cables that should conform to some kind of interface standard and you have slew-limited driver.
