I made a joke on Facebook a few years back about true 'full stack' development. It was a post talking about some code I was writing to do some math computation on a simple OS I had written, running on a CPU I designed using my own custom instruction set, implemented in logic on a physical PCB I also designed and assembled. Of course even this is really only 'partial stack', since I didn't do the VLSI design of the 74x series ICs I was using. So when I think full stack, I think high level code all the way down the transistors. Anything else is weak sauce. ;) ;).
