The seven deadly sins of software deployment

While reading this, I knew I was missing something, as most of the technical part made sense but some of the form didn't.
I actually had to search this "medieval seven deadly sins" to find I missed some mythological background to get it all.

Now I think I understand a bit more. I had actually encountered it before (though it was in my native language so I didn't do the link before I checked how it translated in my language) but didn't take the time to look it up. Now it's done.
