Last week our department drama queen was showing off Visual Studio’s ability to create a visual code map.
He focused on one “ball of mud”, vilifying the number of references, naming, etc and bragging he’s been cleaning up the code. Typical “Oooohhh…this code is such a mess…good thing I’m fixing it all..” nonsense. Drama queen forgot I wrote that ‘ball of mud’

Me: “So, what exactly are you changing?”
DK: “Everything. It’s a mess”
Me: “OK, are any of the references changing? What exactly is the improvement?”
DK: “There are methods that accept Lists. They should take IEnumerables.”
Me: “How is that an improvement?”
<in a somewhat condescending tone>
DK: “Uh…testability. Took me almost two weeks to make all the changes. It was a lot of work, but now the code is at least readable now.”
Me: “Did you write any tests?”
DK: “Um…no…I have no idea what uses these projects.”
Me: “Yes you do, you showed me map.”
DK: “Yes, but I don’t know how they are being used. All the map shows are the dependencies.”
Me: “Do you know where the changes are being deployed?”
DK: “I suppose the support team knows. Not really our problem.”
Me: “You’re kinda right. It’s not anyone’s problem.”
DK: “Wha…huh…what do you mean?”
Me: “That code has been depreciated ever since the business process changed over 4 years ago.”
DK: “Nooo…are you sure? The references were everywhere.”
Me: “Not according to your map. Looks like just one solution. It can be deleted, let me do that real quick”
<I delete the solution+code from source control>
Me: “Man, sorry you wasted all that time.”

I could tell he was kinda’ pissed and I wasn’t really sorry. :)
