It would be ad hominen argument if it was an argument, not a side note. Whereas, in your case, you used to dismiss my position as "no real programmer needs to consult the Wikipedia for definitions" (according to whom, you?).

Since you failed to cite any third party source for definitions, whether your definitions are actually conventional depend solely on your authority as a programmer, in contrast to me, who cited Wikipedia (and there are many others I can cite too). An attack on your authority is no longer a fallacy, but, towards me, it is, since I never relied on my authority as a programmer.

Never mind the fact that being a good programmer doesn't mean you know the definition of technical terms.
