In 2009, I was working hard at a startup in Pittsburgh, and in the late evenings of coding, I developed a GNU Emacs habit. The thing about Emacs is that it's just too versatile to close. Whether you're writing code, writing articles about open source, jotting down a task list, or even playing music, you can do it all from within Emacs. And every time you think you've found a task outside of Emacs, you discover an Emacs mode to prove you wrong. One of my favorite reasons to not close Emacs is its file manager, called directory editor or just Dired.

Applying the open source development paradigm to software results in faster innovation, better products, and lower costs.

Over the last six years, I’ve been able to contribute to Private Browsing, Tracking Protection, Containers, Monitor, […]

I tend to enjoy lightweight applications. They're good for low spec computers, for remote shells, for the impatient user (OK, I admit, that's me), and for the systems we scrap together to fight the inevitable zombie apocalypse. In my search for a perfect blend of a lightweight application with all the modern conveniences we've learned from experience, I stumbled across a file manager called nnn.
