Things are starting to wind down in this series, and as much fun as I've had writing it, mostly I hope it has helped someone out there use start using a Raspberry Pi for education or entertainment. Maybe the articles convinced you to buy your first Raspberry Pi or perhaps helped you rediscover the device that was collecting dust in a drawer. If any of that is true, I'll consider the series a success.

Elasticsearch's parent company, Elastic, calls this move FUD.

Wiki.js is an open source, modern and powerful wiki app based on Node.js, Git, and Markdown. Wiki.js runs on the flamingly fast Node.js engine and is optimized to conserve CPU resources.

SB Components’ open-spec, Raspberry Pi powered “PiArm” robotic arm and gripper kit offers 6-axis digital servos and 360° rotation freedom. SB Components has gone to Kickstarter to launch an open source hardware and software PiArm robotic arm kit aimed at the DIY maker and education markets. The PiArm starts at a super early bird price […]

Matthew Wilcox recently realized there might be a value in depending on C extensions provided by the Plan 9 variant of the C programming language. All it would require is using the -fplan9-extensions command-line argument when compiling the kernel.

BackBox includes a suite of ethical hacking tools, geared specifically toward pentesting. These testing tools include the likes of:

Recently, I shared how upon leaving university in 1994 with a degree in English literature and theology, I somehow managed to land a job running a web server in a world where people didn't really know what a web server was yet. And by "in a world," I don't just mean within the organisation in which I worked, but the world in general. The web was new—really new—and people were still trying to get their heads around it. read more

I am a fan of retro gaming and preserving the computer history that lead us to where we are today. I think most programmers have a machine that helped develop their love for programming; for me that was the Commodore Amiga. I am currently restoring a couple of Amigas to get them back to working order. read more

In the mid-'90s, I started college as a math major, and, even though I graduated with a computer science degree, I had taken enough classes to graduate with a minor—and only two classes short of a double-major—in math. At the time, I was introduced to an application called Mathematica by Wolfram, where we would take many of our algebraic and differential equations from the blackboard into the computer. read more

Linus Torvalds at last made the jump with the recent release of kernel 5.0. Although Linus likes to say that his only reason to move on to the next integer is when he runs out of fingers and toes with which to count the fractional part of the version number, the truth is this kernel is pretty loaded with new features.

A review of open source 3D printers.

More than a year ago we started developing Firecracker, a virtual machine monitor (VMM) that runs on top of KVM (the kernel-based virtual machine). We wanted to create a lightweight VMM that starts virtual machines (VMs) in a fraction of a second, with a low memory footprint, to enable high-density cloud environments. read more

Advantech has launched a $360, Verizon-certified “ICR-3211B” LTE Cat-M1 router with a 1GHz Cortex-A8 SoC, 2x LAN ports, triple SIM slots, “last gasp” supercap, and a user-programmable Linux stack. Advantech has launched a line of industrial routers starting with a compact, highly redundant ICR-3211B model that is pre-certified for Verizon’s new low-power wide-area (LPWA) Cat-M1 […]

Backed by Esperanto, Google, SiFive, and Western Digital, the CHIPS Alliance will foster a collaborative environment for creating and deploying new open-source chip designs. These will be used across the entire spectrum of computing. This will include mobile, computing, consumer electronics, and Internet of Things (IoT) chip and System on a Chip (SoC) designs.

Anchor is a lightweight open source blog CMS written in PHP. Anchor's source code is hosted on GitHub. In this tutorial, we will install the Anchor CMS using PHP, Nginx, MariaDB and Composer on the Fedora 29 system.

If you are following our C programming tutorial series, you should be aware of the concept of variables. While we've discussed the basics of variables, there's another important aspect related to variables that we'll be discussing here: scope of variables.

Are you new to using Fedora, or have a question about using Fedora? Got a story or helpful hint for Fedora that you want to share? You want to check out Fedora Discussion. It is a relatively new place where users and members of the Fedora Community meet to discuss, ask questions, and interact. Fedora […]

I recently discovered a new daily puzzle, known as "spelling bee", that the New York Times offers online. I do pretty well at this puzzle, but I've never managed to find all of the hidden words. Nevertheless, I have become queen bee on a few occasions. How? The answer is simple. I cheated. How? Using Python, of course.
