Further, it's not an ad hominem to insult somebody while arguing with them. It's only an ad hominem if the insult is the basis of your argument.

The entire basis of the argument I am replying to is that people shouldn't be criticizing because "meanwhile back in their own lives, they still have to argue with project managers over the "right" way to get code done."

So that is the very definition of an ad hominem. The comment had no actual rebuttal to said 'shitting' that it was attacking.
