This presentation has a series of coding habits that can cause problems if applied blindly:
I have seen many of these bad habits and I have quite often used them because they are my habits as well. I am unsure how we can lose these habits easily because some are embedded in the team and getting the entire team to change is not easy.
I like that he explains the fact that some of these start small and grow to be a problem. You have to be very attentive and make sure you don’t start on the wrong path.
