Container image short names in Podman | Enable Sysadmin
This new feature, pulling images with Podman by using short names, includes more security, greater convenience, and is another step forward for container management.
[...]
When people approach me to talk about Podman and containers, I usually ask if they are familiar with Docker. Most people are, and the conversations quickly move beyond the fact that Podman can act as a drop-in replacement for Docker. In fact, there are many useful and innovative features that make Podman special. Podman has excellent rootless support, it can generate systemd unit files for easily containerizing systemd services, and it has a powerful RESTful API that allows for running Podman on macOS and Windows. Those are just a few of the great features.

The Ultimate Guide to Dolphin Emulator. - Make Tech Easier
Today you can find hundreds of emulators for dozens of old systems for multiple platforms. However, Dolphin manages to stand out from the crowd by achieving something almost impossible: combining advanced features and a high degree of compatibility with ease of use.
With Dolphin, which is available for Windows, macOS, Linux, and Android, you gain access to the vast majority of titles for Nintendo’s GameCube and Wii consoles. Theoretically, since it’s easy to use, you only have to run it, add some games, and play. Practically, though, it’s worth investing some time to customize and configure Dolphin to your liking. This way, you’ll be able to take advantage of its advanced features and play your games better than you would on the actual hardware.

Terminal Vitality
Ever since Douglas Engelbart flipped over a trackball and discovered a mouse, our interactions with computers have shifted from linguistics to hieroglyphics. That is, instead of typing commands at a prompt in what we now call a Command Line Interface (CLI), we click little icons and drag them to other little icons to guide our machines to perform the tasks we desire.
Apple led the way to commercialization of this concept we now call the Graphical User Interface (GUI), replacing its pioneering and mostly keyboard-driven Apple // microcomputer with the original GUI-only Macintosh. After quickly responding with an almost unusable Windows 1.0 release, Microsoft piled on in later versions with the Start menu and push button toolbars that together solidified mouse-driven operating systems as the default interface for the rest of us. Linux, along with its inspiration Unix, had long championed many users running many programs simultaneously through an insanely powerful CLI. It thus joined the GUI party late with its likewise insanely powerful yet famously insecure X-Windows framework and the many GUIs such as KDE and Gnome that it eventually supported.

If you want a home security system to tell you if someone is lurking around your property, you don't need an expensive, proprietary solution from a third-party vendor. You can set up your own system using a Raspberry Pi, a passive infrared (PIR) motion sensor, and an LTE modem that will send SMS messages whenever it detects movement.

Create a machine learning model with Bash | Opensource.com
Machine learning is a powerful computing capability for predicting or forecasting things that conventional algorithms find challenging. The machine learning journey begins with collecting and preparing data—a lot of it—then it builds mathematical models based on that data. While multiple tools can be used for these tasks, I like to use the shell.
A shell is an interface for performing operations using a defined language. This language can be invoked interactively or scripted. The concept of the shell was introduced in Unix operating systems in the 1970s. Some of the most popular shells include Bash, tcsh, and Zsh. They are available for all operating systems, including Linux, macOS, and Windows, which gives them high portability. For this exercise, I'll use Bash.
