I used to work as a contract developer for a consulting firm. I kept the project repo in my Dropbox. Everything got uploaded. This was obviously a security issue, but nobody asked, and I didn't tell. Dropbox saved my ass multiple times. The cost of accidentally losing uncommitted changes seems much greater than the probability weighted cost of somebody 1. hacking Dropbox, and 2. giving a shit about the client's project. I would do it again. #thuglife
