Raspberry Pi is releasing an add-on that will let you use many of its tiny, inexpensive computers to control certain Lego robot motors and sensors. The add-on is called the Build HAT (HAT stands for Hardware Attached on Top), and slotting it onto a Raspberry Pi’s GPIO pins will give you four ports that you can use to control Lego Education’s SPIKE components, which the HAT and its software are specially designed for. It’ll also connect to most other parts that use an LPF2 connector, including the components from the Lego Mindstorms robot inventor kit.

When it comes to image manipulation and editing, there are many tools available. However, options like GIMP are not necessarily the solution to everything. Yes, GIMP offers plenty of features for beginners and advanced users, but it could be time-consuming to learn something and apply visual enhancements to any image you want. Annotator is an impressive open-source tool that lets you do a lot of things in a couple of clicks.

The troubled .NET Foundation was intended to "borrow as much as possible from the GNOME Foundation," according to Miguel de Icaza, co-founder of GNOME and now at Microsoft, who was involved in its original design. De Icaza's remarks were triggered by a post from Reed Copsey, president of earth science research company C Tech and executive director of the F# Foundation.

In my programming work, I often need to know the memory used by web applications. A rough estimate is usually enough before getting down to details and browser profiling tools.

This article explains how to transition a typical container setup from Raspberry Pi OS to Fedora Linux at the example of the Traefik reverse-proxy. We start with an already setup Fedora Linux to keep this one to the point, which is getting to know fundamental differences and options when first touching down on Fedora Linux and podman.

Canonical has released Ubuntu 21.10, or "Impish Indri" as this one is known. This is the last major version before next year's long-term support release of Ubuntu 22.04, and serves as a good preview of some of the changes coming for those who stick with LTS releases.

As the Podman machine function becomes more used—particularly on Macs—there have been many questions about how this all works. Some of what is tossed around on the internet is pure speculation, so this article aims to eliminate any speculation.

There are plenty of Linux-based laptops available. There are also mini-PCs preloaded with Linux. A few Linux-based smartphones are also present in the market. How about tablets? Are there some good Linux-based tablets? The answer is not straightforward.

We've been wondering what Valve had planned to show off Steam Deck compatibility for games and now they've launched Deck Verified as their answer.

Recently, the helloSystem devs released the newest version of their operating system. helloSystem is a newer project that wants to create a simple and easy to use operating system and is based on FreeBSD. Let’s take a look at what that means to you and me.

If you’ve just got your Raspberry Pi, you probably noticed it lacks a power button. This might leave you wondering how to turn the miniature computer on and off. Let’s walk through it all, step by step.

I play a lot of tabletop role-playing games (RPGs), in terms of both frequency and variety. Generally, I prefer playing RPGs in person with friends, but over the past two years, I've been playing online. At first, I wasn't sure how to run a long-term game online. I knew there were a lot of tools out there to make it possible, but none of them interested me until I discovered the world of open source online tabletop gaming. With a small collection of open source applications, I've been able to run all my games exclusively on open source.

The Mastering Linux and Git Certification Bundle offers insight into the open-source operating system, even if you’ve never touched a line of Linux code before. Everybody knows about Windows and MacOS. But everybody doesn’t know serious computing. While those operating systems may run all the personal PCs you see, the world’s most powerful computers run on the operating system real experts swear by: Linux.

TCL, which has a habit of showing off display technology that may or may not ever see the light of day, has released a video showing a concept for a set of augmented reality smart glasses with micro LED displays.

Finding a good open source code editor is not hard these days, choosing one can be. Microsoft’s Visual Studio Code and GitHub’s Atom are two of the most popular, feature-rich, IDE-like code editors that have a huge user base and fan following.

There's apparently absolutely no stopping the Blender train, with the developer announcing that Apple has now joined their development fund.

While there is quite an array of Arduino boards to choose from, the Nano is a versatile board suitable for almost all DIY electronic projects. These tiny micro controllers make compact DIY hardware development available to more people than ever before. In the past we have covered reasons you may not want to choose a genuine Arduino for your projects, but today lets take a look at the positives and negatives of the Arduino Nano.

Some people find out about Linux, dive in, then walk away feeling like Linux is a waste of time. That's a pretty broad brush to paint the entire operating system with, but there are some use-cases where Linux is great and others where you might run into some challenges. Here are some frustrations people have expressed about Linux and what you can do about it if you decide that Linux is still for you.

Open source arrived in the pen-and-paper RPG industry back at the turn of the century, when Wizards of the Coast, publisher of Magic: The Gathering and Dungeons & Dragons, developed the Open Game License (OGL). Many publishers have since adopted the OGL themselves or use similar licenses, such as Creative Commons.

Pine64 today announced its latest Linux-powered device, the PinePhone Pro, an update to the original PinePhone which sees a more powerful device running mainline Linux (Manjaro in this case) on a mobile device that works as a cell phone and a desktop computer.
