In this guide, you will learn how Docker volumes interact with containers. You will do this by creating new containers and using volumes to store and share data between them. Then, you'll discover how to clear up space that is left behind by anonymous volumes that are automatically generated by the containers. Finally, you'll learn how to back up your Docker volumes data.

The primary goal of firewall penetration testing is to prevent unauthorized internet access to your organization's internal network, or check to make sure your security policy is doing what you think it's doing. In order to successfully test your organization's firewall, you must think like the adversary. Collecting intelligence on the network, such as operating system and firewall type, are important to know in order to proceed with the penetration test.

Firefly has posted specs for an “ITX-3588J” Mini-ITX board with an octa-core -A76 and -A55 Rockchip RK3588, up to 32GB RAM and 128GB eMMC, 4x SATA, 3x HDMI, 2x GbE, PoE, 2x M.2, and PCIe Gen3.

There are lots of reasons to build your own Linux distribution. Some projects strive for license purity, others for performance, and some for a multitude of features. Then there are projects which aim to present a certain look, whether it is unique or a copy of another operating system. This week we begin with a look at XeroLinux, a project which strives to offer lots of eye candy on top of an Arch Linux base. Are you interested in developing your own operating system?

Container platforms and edge computing continue to grow, powering major networks and applications across the globe, and Java technologies have evolved new features and improved performance to match steps with modern infrastructure.

A groupware solution is a must-have, whether you're working in a small organization, a medium-sized company, or a large enterprise. It promotes collaboration and glues teams together. Are you looking for an open source alternative to the big players? Maybe EGroupware can replace Microsoft 365 or Google Workspace in your team soon.

Argon Forty loves releasing cases with names that have permutations of the word “ONE.” So far we’ve had the Argon ONE (and M.2), NEO and now we have the EON. But rather than another wedge shaped Raspberry Pi case bound for our desktop, the EON is bound for our living room, office or small business where it helps turn your Pi into a network-attached storage drive (NAS).

The National Science Foundation (NSF) wants to grow the community of researchers who develop and contribute to open source and enable pathways for collaboration that lead to new technologies that have broad impacts on society.

If you’ve ever tried to run a script from the command line in Linux and gotten an error message saying that it’s not executable or attempted to enter a directory only to be blocked by the system, you probably don’t have permissions to do those things. Fortunately, if you have the proper rights or the ability to act as a super user (accessible by using sudo), you can change the permissions on files and directories.

Details have emerged about a now-patched high-severity vulnerability in the Linux kernel that could potentially be abused to escape a container in order to execute arbitrary commands on the container host.

I’ve recently explored some of the differences between Java and Groovy when creating and initializing lists and building lists at runtime. I observed the simple facilities provided by Groovy for these purposes in comparison to the complexity required in Java.

If you're a fan of customization and on the lookout for ways to boost your productivity on Linux, then Cerebro is a must-have app for your computer.

Adlink and Congatec have each unveiled Linux-ready COM-HPC Server and COM Express Type 7 modules based on Intel’s Ice Lake-D Xeon D-2700 and D1700 SoCs with up to 20x and 10x cores, respectively, and support for up to 48x PCIe and 8x 10GBASE-KR.

An update that fixes 14 vulnerabilities is now available.

The Linux kernel has spawned an entire family of operating systems known as Linux distributions. There are close to a thousand (or maybe more) distributions that you can install on your computer for free. But when it comes to ease of use and beginner-friendliness, Ubuntu is the name that pops up the most. Why is this so? And why do people recommend Ubuntu as the first distro to Linux beginners? Let's find out.

Are you prepping up for an interview where you may face Linux-related questions? Then read through. This article takes you through 17 important Linux questions with answers that will make you interview-ready. So, let’s begin!

MangoPi has opened $39 preorders for a 40 x 40mm “MangoPi-Nezha MQ” SBC that runs Linux or RT-Smart on a 1GHz, RISC-V based Allwinner F133-A SoC with 64MB DDR2. The SBC supplies 2x Type-C, WiFi, MIPI-DSI, RGB touch, DVP camera, GPIO, and audio I/O.

It’s not every day that an open-source, portable Linux handheld computer gets announced, so I couldn’t resist placing an order for the DevTerm by ClockworkPi back when we first learned about the stylish little terminal, which includes a 1280 x 480 screen (double-wide VGA) and a modular little thermal printer.

In our recent review of the Steam Deck portable console from Valve, we noted that continued updates to the company's Proton compatibility layer would help many games designed for Windows run well on the system's Linux-based SteamOS. For a handful of popular online multiplayer games, though, inherent limitations to anti-cheat support on Linux may prevent compatibility with SteamOS (and the vanilla Steam Deck) indefinitely.
