We have all been there: you spent more time than you are willing to admit reverse engineering a few functions, only to discover that you were looking at the wrong functions. Your entire weekend wasted, or so you think. But, did you really? This talk dives into mistakes I have made in the past, along with commonly attempted shortcuts by many. The focus is not (only) on my mistakes, although you are free to laugh at my expense, but more so on the lessons learnt from them. In short, I hope that I can share the mistakes I made, so you don’t have to!
