I was amused by a prompt I received from Android Studio, requesting permissions to turn off anti-virus scanning for development directories. Which, of course, speeds up compile time dramatically (4 or 5x faster? A seriously non-trivial amount). Development directories, and SDK directories (including SDK binaries).

No more anti-virus protection for the directories that you as a developer should be most concerned about. What could possibly go wrong?

I'd be more concerned if I hadn't already done that, I suppose. Because compiles run so much faster when you do. But I was amused, nonetheless. :-/
