As soon as read "hacking" being used as a synonym for coding/development, I started to get angry. I still read it just in case I was wrong, just to end up being right, and angry.
In the public however, "hacking" is often more used synonymous to "cracking", which I find very unsettling and sad. At least there is nowadays some awareness that there is a different meaning to it. I guess that the word "hackathon" helped to change the public perception.
