Yet another little nodeshell leaps out of the ether of everything screaming out "Fill me! Fill me!"
There are two types of individual who can suffer from exhaustive programming disorder, and they lie at the two opposite ends of the spectrum of people who make computers work.
The first is the obssessive hacker, coding (and maybe noding) through the night and on into the early hours of the morning, fuelled by the obligatory diet of Coke, caffeine and nicotine. This kind of EPD sufferer labours away in front of his screen for love, for the sheer pleasure that comes from altering this line just so, tweaking that function like that, and ultimately producing a product that millions will find useful.
The other EPD sufferer is probably far more common. It is the Corporate software engineer, stuck in his cubicle, trying to iron out the latest bugs in the mass-market, high-cost product that the marketing droids promised would be shipping last Tuesday. Possibly also fuelled by the same combination of junk food and cigarettes, this person's motivation is not pride in his work, or pleasure, or a will to do good for the community, but motivated instead by fear of unemployment, bankruptcy and homelessness.
I've swung between both of these roles at various points in my life, and know I think (at least I like to hope) that I've struck a happy medium -- I neither work too hard nor play too hard.
