I just submitted a change today that affected 266,259 different build targets within google3. I was slightly terrified to make a change of this magnitude, having been at Google for less than three months, but I ran all the affected tests multiple times and it doesn't seem to have broken anything. (Fingers crossed!) Working on the google codebase is pretty awesome. This week I've made changes/improvements to libraries owned by three different teams (not counting my own), in C++ and python, when my main project is all in Java. It's super fun. The code search tool is great - it's ridiculously fast, and makes navigating through the codebase very easy.
