We learned a lot about Kubernetes in 2022. It seems every year, Kubernetes gets better and better. For all those beginners out there, this year's coverage is wide-ranging and detailed, including a couple of new eBooks. This article covers what I found to be the best Kubernetes articles of 2022.

n the beginning, there was the command line. While modern Linux distributions include graphical desktops like GNOME and KDE, the command line remains one of the power features of every Linux system. With the command line, you can leverage a rich set of instructions to edit and manipulate files, control your system, and automate processes. This year, our contributors wrote a lot of great articles about the Linux command line. Here are five of my favorite topics.

Meanwhile the next-gen Linux filesystems are going nowhere fast. The forthcoming Linux kernel 6.2 should see improved filesystem handling, including performance gains for SD cards and USB keys, as well as FUSE. As for the next-gen storage subsystems… not so much.…

Double Commander is a graphical dual-pane file manager for Linux, in the tradition of Midnight Commander (mc). While Midnight Commander (like the DOS application Norton Commander before it) has its fans, its audience is limited by the fact that it only runs in a terminal window. Not everyone wants to use a "flat" interface embedded in a terminal to browse their file system, and so Double Commander provides a similar interface in a way that feels familiar to many desktop users.

While developing with Python as a student, I found that I needed some private centralized storage. This was so I could store binary and text data files, as well as Python packages. I found the answer in Artipie, an open source self-hosted software repository manager.

SpaceFM is a tabbed file manager for Linux using the GTK toolkit, so it fits right in on desktops like GNOME, Mate, Cinnamon, and others. SpaceFM also features a built-in device manager system, so it's particularly good for window managers, like Fluxbox or fvwm, which typically don't include a graphical device manager. If you're happy with the file managers on Linux, but you want to try one that's a little bit different in design, SpaceFM is worth a look.

I started getting requests to "turn my camera on" when video calling people. This was a problem because I didn't have a webcam. I thought about buying one, but then I realized I had a perfectly good Canon EOS Rebel XS DSLR from 2008 lying around on my shelf. This camera has a mini-USB port, so naturally, I pondered: Did a DSLR, mini-USB port, and a desktop PC mean I could have a webcam? There's just one problem. My Canon EOS Rebel XS isn't capable of recording video. It can take some nice pictures, but that's about it. So that's the end of that. Or is it?

In a previous article, I showed how the Rexx scripting language is both powerful and easy to use. It uses specific techniques to reconcile these two goals that are often considered in conflict. This article walks you through two example Rexx scripts so you can get a feel for the language.
