Does anyone know to what kind of books or reference is the author talking about when talking about the "15 years of free literature on how to run large-scale online projects" I've seen in the comments that damian2000 (http://news.ycombinator.com/item?id=4781706 http://news.ycombinator.com/item?id=4781706) has suggested "Peopleware: Productive Projects and Teams" by DeMarco & Lister. any other suggestions?
