There use to be a mythological creature on irc from south America (sorry forgot the specifics) who was both a 10x dev and a 10x mathematician. One day he showed a picture of his computer. It was a low end laptop with a tft monitor and an external keyboard because the screen and the keyboard didn't work. It explained everything, the machine was just good enough to write code, do math, read stack exchange and lurk irc with his ghosts.
