I am a PCB designer and C programmer, which means I spend my days persuading electrons to behave and my nights arguing with compilers about whose fault it really is. I design intricate copper runes that occasionally turn into functioning circuits, and write C code that works - either by skill, luck, or mild intimidation. When things go wrong (which they never do, except when they do), I bravely debug systems that were definitely working five minutes ago. I have a deep and abiding respect for datasheets, though I suspect they are written to test human endurance.
Please remain calm while I make things worse.
