Background

I posted this gist a few years ago as a quick memo for myself. I never expect this little gist to rank up in top 3 search result and getting so many helpful feedbacks. Since it gets viewed quite often, I decided to revise this post so that it may be a little more helpful. Thank you again for the feedback!
