What hardware do you use?
My tools for national security consulting are primarily a semi-auto .22 rifle with a silencer. They are virtually completely silent and can pierce car doors and other light armor. They are perfect for urban environments.
My accessory tools are mostly extremely strong espresso and research chemicals from China that are classed as "Smart Drugs". They allow me to solve 2nd order partial differential equations in my head and to spontaneously create 4 dimensional images of software structures that I can mentally manipulate.
