>At Google, no code, for any product, for any project, gets checked in until it gets a positive review. I can't believe that's true as stated. I am guessing "No code is put to a branch which is used by others without review or "No code is put into production without review". I can't imagine "You aren't allowed to check in things without getting signoff of others" working period.
Don't believe all of it.
