Alexey Koval has a nice post illustrating some of his devops workflow using Emacs. In a way, devops brings together most of the chores that folks use Emacs for. You edit files on remote machines to adjust configurations, you write scripts and programs, and you write prose in the form of documentation. Emacs, of course, excels in all of these tasks.
Koval embedded some short videos that illustrate these tasks and includes commentary on useful packages that help you get things done. If you’re interested in seeing how Emacs can be used for various tasks, this post is worth checking out.
Oh, and one more thing: Happy New Year from us here at the International Irreal Headquarters
