I'm a troubleshooter; when I solve problems, I try to solve classes of problems, not just the one instance presented. This means when I fix a problem, it stays fixed, it doesn't merely stop being broken. I know the pain of entering a legacy system without a map of the territory, so I always leave behind documentation for "the next guy."
I spend much of my time "teaching" the mechanical servants that are autistic, illiterate, but hard-working; computers can be valuable servants, but they need to be taught how to do what you want of them.
My roommate in college called me 「莫在」, and the name stuck.
