I can't remember the first time I was introduced to the term, I'm guessing it was via The Waterboy and Mama Boucher:
Bobby Boucher: [after Reading A Question About Benjamin Franklin] Ben Franklin Young Bobby Boucher: [Flashback To Bobby's Childhood] Mama, When Did Ben Franklin Invent Electricity? Mama Boucher: That's Nonsense, I Invented Electricity. Ben Franklin Is The Devil!
Today I posted something to the effect on Twitter. I've decided to start adding things I would consider The Devil, in Mama Boucher's terms, here.
Cary Millsap is The Devil. Why? A year or 2 ago he posted a link on Twitter about why we don't need to double-space anymore after a period. Each and every time I go to double-tap the space bar, I think of that post and curse Cary appropriately.
Triggers are probably The Devil. Rarely have I seen them implemented in a halfway decent manner. Usually, they're used as some work-around because someone was too lazy to update their PL/SQL...or just couldn't figure out a way to accomplish their goal without them (say, like removing direct INSERT/UPDATE/DELETE privileges on the source table...?).
From that last post, tnsnames.ora can be The Devil.
I would say that commas in front of the line are The Devil.
My friend Jason Baer is The Devil. Go to 2:40 in:
That's all I have for now.
What do you consider The Devil?
Update Me. I can think of at least 47 people who believe I am The Devil. Man...how could I forget something like that.
