11/05/2015, 3:06 PMwhy does JetBrains use a coding style in which there are bazillions of tiny commits? I don’t think I’ve seen this in other projects. - m

11/05/2015, 3:12 PM@mikehearn: most of the commits aren’t so tiny in fact. I guess the reason is that we don’t spend the time on squashing commits before merging them into master - n
