I don't go to r/programming anymore since they censor things like the github CoC submission
If you want to learn about things like the github CoC go to r/KotakuInAction.
If you want to learn out about cool programming things go to r/programming.
If you don't understand this advice or are convinced that you are Making a Stand against the SJW Menace, go to r/KotakuInAction and stay there.
