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.

The xG24 Explorer Kit is a low-cost embedded platform based on the EFR32MG24 Wireless System-on-Chip. This compact board integrates a 2.4GHz radio in addition to one mikroBUS socket, one Qwicc connector and a SEGGER J-Link onboard debugger. According to the datasheet, this development kit integrates the Silicon Labs EFR32MG24 Wireless Gecko SoC with the following […]

The end-of-life (EOL) for PHP 7.4 was Monday, November 28, 2022. If you’re like me, that date snuck up much faster than anticipated. While your PHP 7.4 code isn’t going to immediately stop working, you do need to begin making plans for the future of this codebase. What are your options?

It also boasts MemTest86+ 6, which now can boot and run on UEFI machines. SystemRescue 9.06 may only be a point release, but it has some good stuff including the newly released Xfce, MemTest86+ version 6, and a new USB-key-writing tool.…

GoCD is an open-source continuous delivery and automation system. GoCD excels at modeling complex CD workflows for fast feedback with its modeling constructs, parallel execution, and dependency management. This tutorial will teach you to install and configure GoCD on a Ubuntu 22.04 server.

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.

Ghost is an open-source blogging platform to help you create a professional-looking blog. This tutorial will explore how to install Ghost CMS using Nginx and MySQL on a server powered by Rocky Linux 9.

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.

The lions shall lie down with the lamb on 'cross-industry' Speedometer v.3. Apple, Google and Mozilla are teaming up to develop a new version of the Speedometer browser benchmark that they say will score web browser performance in a novel way: one that reflects user journeys, not under-the-hood streamlining. …

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.

Introduction Fedora IoT is a foundation for Internet of Things (IoT) and Device Edge ecosystems. It’s a secure, immutable, and image-based operating system that supports the deployment of containerized applications. We’ll discuss how you can run Fedora IoT on a Raspberry Pi to deploy a rootless Podman container. Running Fedora IoT on Raspberry Pi Prerequisites: […]

Dragonfly Navigator is a general-purpose file manager written in Python and Qt. It's easy to install, easy to use, and a great example of what Python can do.

SB Components just launched a user-friendly DIY modular laptop on Kickstarter. The LapPi 2.0 is being offered with the Raspberry Pi 4 board, but the company mentioned that the product should be compatible with other SBCs i.e., RockPi, Asus Tinker, etc. LapPi 2.0 components include a pair of 5 Watt 8 Ohm speakers, a 7” […]

Every so often, I find myself needing to calculate complementary colors. For example, I might be making a line graph in a web app or bar graphs for a report. When this happens, I want to use complementary colors to have the maximum "visual difference" between the lines or bars. Many online resources explain how to do this and offer formulas, but I think it's high time for a Groovy color calculator. So please follow along.

Open source software projects often have a very diverse user group. Some users might be very adept at using the system and need very little documentation. But other users may be beginners. These users need more help in setting up the system and learning how to use it. Writing documentation that suits both user groups can be daunting. ... consider a third option — dynamic documentation.

In the late 1980s and throughout the 1990s, there was a popular file manager for DOS called Norton Commander. It was beloved by many computer users of the day, but it fell out of favor as graphical file managers became the default. Fortunately for fans of the original commander, and those who missed out on the original, an open source file manager with a similar design was released, called Midnight Commander or, more commonly, just mc.

Every year, Itch.io hosts Open Jam, a game jam where developers build an open source video game over a weekend. This year's Open Jam ran from October 28th to October 31st. Open Jam is a friendly competition with no prizes, which makes it a great opportunity to try new things, experiment with a new game idea, or learn a new programming language.
