Dr Hjkl on the Command Line

The first time I used vi was in a college programming course. It was the default editor on the computer lab's UNIX systems we used to compile our assignments. I remember when our professor first introduced vi and explained that you used the hjkl keys to move your cursor around instead of the arrow keys. more>>

Infinite BusyBox with systemd

Lightweight virtual containers with PID 1. In this article, I demonstrate a method to build one Linux system within another using the latest utilities within the systemd suite of management tools. The guest OS container design focuses upon BusyBox and Dropbear for the userspace system utilities, but I also work through methods for running more general application software so the containers are actually useful. more>>

Chrome-Colored Parakeets

I personally like Google's Chrome interface. It's simple, fast, elegant and did I mention fast? Unfortunately, I don't like how locked down the Chrome OS is on a Chromebook, nor do I like its total dependence on Google.
