I only see a list if four "Don'ts". Would have been nice to have some "Do instead's". Of course I can try to think about "good" ways to access my secret other way than hard coded, but then I may not be the audience.

For articles like "X mistakes in topic Y" I expect some solutions to solve the problems. The other way is only pointing at fools for me.
