Is the ShiftOut tutorial on the official Arduino website really wrong regarding the capacitor? I'm talking about this tutorial "Serial to Parallel Shifting-Out with a 74HC595" from the official Arduino website. It provides the following schematic:



I've read a couple of times now, that the placement of the capacitor is wrong:


  This is a well known shit tutorial which for some unknown reason they refuse to fix.
  That capacitor should be connected between the Vcc pin and ground, NOT the latch pin.

They recommend this placement:



Who's right? Please explain where to place the capacitor. Can the arduino even be damaged?
You can figure out the impedance of that capacitor for high frequency signal....

What they have there is really a low pass filter.

Terrible ideal to out that big of a capacitor there.
