One of my favorite applications of Org mode and Babel is demonstrated by Howard Abrams’ post and video on what he calls Literate DevOps. The basic idea is that he documents his work in an Org file complete with the actual code that he uses. What Babel makes possible is that he executes the code from inside Org mode and the results are automatically added to his Org file. In the end, he has a complete record of what he did along with the results. That makes the process easily reproducible and he can send to file to a colleague wishing to build on his work or needing a go-by for a similar project.
Vincent Bernat has taken Abrams’ DevOps idea and applied it to network operations. He calls it netops. If you’re working in network operations and want a nice way of documenting your work, take a look at Bernat’s post and the accompanying three videos. As with DevOps, everything you do is documented along with the code and results.
If you aren’t a network engineer you probably won’t understand everything he’s doing but you can still follow his process. My only complaint is that the videos have no audio; Bernat just types in what he is going to do. I find videos like that harder to follow but they’re still definitely worth watching.
