Here's a debate that refuses to die: given a choice, would you rather use spaces or tabs? An episode of Silicon Valley last season had a bit on this. Now we have more data to analyze people's behavior. A Google developer has looked into 400,000 GitHub repositories -- 1 billion files, 14 terabytes to find that programmers with interest in specific languages do seem to prefer either tabs or spaces. Spoiler alert: space wins, like all the time.
