Ansible is an agentless IT automation tool that unravels the mystery of how work gets done. Many sysadmins run Ansible ad hoc commands or playbooks daily to handle their automated tasks. They rely on Ansible's default command-line interface (CLI) output to visualize and understand what happens after their command or playbook finishes running.

Networked computers are so common these days that most of us take it for granted that a computer on one side of a room can contact one on the other side of the room, much less the other side of the world. When it works as designed, networking is what makes the Internet, the cloud, file shares, media streaming, remote administration, printing, and much more possible. When something goes wrong, it can sometimes be challenging to diagnose. One of the most fundamental diagnostic tools for networked connectivity is the ping command.

In June of 2020, we published an article related to running Docker and Fedora 32. We described various workarounds that were required to run Docker, and we explained the bothersome situation at that time. But Docker has evolved, and it’s time to return to our previous tutorial. Thus, today we’ll talk about using Docker on Fedora Linux 35.

If Linux is your primary working environment, then you might be familiar with the Executable and Linkable Format (ELF), the main file format used for executables, libraries, core-dumps, and more, on Linux. I've written articles covering native Linux tools to understand ELF binaries, beginning with how ELF binaries are built, followed by some general tips on how to analyze ELF binaries. If you are not familiar with ELF and executables in general, I suggest reading these articles first.

The refreshed Juno lineup includes the budget-oriented 15-inch Nyx models with AMD Ryzen 7 5700U processors and integrated Vega 7 graphics, the Saturn mid-ranger with intel COre i7-11800H and RTX 3050 / 3050 Ti dGPU options, and the Neptune high-end solutions with i7-11800H and Max-Q variants of the RTX 3070 / 3080 dGPUs.

Pandemic-driven supply chain problems have prompted the first-ever price increase for a Raspberry Pi product, according to Raspberry Pi founder Eben Upton. Acknowledging that the 2GB configuration of the Raspberry Pi 4 and the Raspberry Pi Zero had been particularly hard-hit by shortages, Upton announced that the price of the 2GB Pi 4 would increase from $35 to $45 and that a previously discontinued version of the Pi 4 with 1GB of RAM would be reintroduced at $35.

Microsoft has issued a stark warning to system administrators, advising them of the importance of updating PowerShell 7 as soon as possible. Versions prior to PowerShell 7.0.8 and PowerShell 7.1.5 are vulnerable to a .NET Core Information Disclosure flaw that is being tracked as CVE-2021-41355. There is a degree of urgency to upgrading to a non-vulnerable version of PowerShell, as the flaw could expose credentials in plain text in Linux.

The major US TV vendor Vizio stands accused of failing to fulfill the basic requirements of the General Public License (GPL) in its TV source code. The Software Freedom Conservancy (SFC), a non-profit organization that promotes open-source software and defends the free software General Public License (GPL), has sued major TV vendor Vizio for abusing the GPL.

Linux users like to game, too, and the Juno Neptune 17-inch V3 laptop announced this week ensures that people on Ubuntu can play their favorite titles on the go. Keeping up with the Alienwares, Asus ROGs, and other Windows-focused gaming brands, the new portable packs up to an RTX 3080 discrete graphics card and the 8-core Intel Core i7-11800H. And it lets you experience all the action on a spacious, 17.3-inch screen with a 144 Hz refresh rate. A colorfully backlit keyboard completes the package.

Intel has teased a new tech it calls "Software Defined Silicon" (SDSi) but is saying almost nothing about it – and has told The Register it could amount to nothing. SDSi popped up around three weeks ago in a post to the Linux Kernel mailing list, in which an Intel Linux software engineer named David Box described it as "a post-manufacturing mechanism for activating additional silicon features".

Visual Studio Code has become one of the most popular IDEs for coding. This tutorial will teach you how to install Visual Studio Code IDE using the code-server application on your Rocky Linux 8 server. You will also expose it via a public domain along with SSL support.

Halloween decor seems to get more intense every year for makers. Hel Gibbons' latest project demonstrates this annual phenomenon with a huge, eerie 3D-printed doll modelled on the "Red Light, Green Light" game from the popular Netflix series Squid Game. Not only is this project beautifully crafted from scratch, but it also features our favorite Raspberry Pi microcontroller, the RP2040.

I got introduced to the markdown format a few years ago when I began to explore Jupyter Notebooks. Many of the other writers at Opensource.com knew markdown, but it was a skill that was unfamiliar to me. Markdown is a standard way of writing text, in which you use minimal notation to markup how you want the text styled. For instance, instead of clicking a button to make a word bold, you surround the word with two asterisks (**word**).
