Y'all have your rubber duck to debug, but I have my own technic: the SO debugging.

It simply consists as asking your question as you'd normally do, but while doing so, you still think about your issue, and how people not knowing your problem but still knowing about dev would react to your question, making you asking other related question (SO's related question might also help).

IMHO, the most important part is the "related" question, that helps you to think outside the box. It makes your problematic progress a lot, and has the gift of not making you loosing any hope ; and if you ever block for good, your question will look less silly than at the beginning
