This week saw the annual check-in with Linux creator Linus Torvalds at the Open Source Summit North America, this year held in Seattle (as well as virtually). Torvalds took the stage Tuesday in the ballroom at the Hyatt Regency Seattle for the event’s traditional half-hour of questions from Dirk Hohndel, an early Linux contributor (now also the chief open source officer and vice president at VMware) in an afternoon keynote session.

Halloween is coming, and what better way to celebrate the season than by using machine learning and a Raspberry Pi to accomplish something spooky! This year I’ve built a mannequin head that uses person detection and a simple servo motor to detect when a person is walking by and turn the head to follow them. I’m using a simple styrofoam mannequin head with some coloured in eyes from the dollar store, but you’re welcome to dress it up to fit your house’s theme or use a completely different kind of head or object. As long as you can use a servo to rotate it, the result is the same.

Users who have recently migrated from Windows to Linux often wonder if they can run Windows apps and programs on their new system. The answer to this affects a user's perspective of Linux in general, since operating systems should be easy to use and at the same time, welcoming to the idea of running different file formats.

There have been many false dawns for Linux gaming, but in recent years things have been improving unabated. The launch of the Proton compatibility layer meant that thousands of DirectX-only games can now be translated to Vulkan and therefore work on Linux, while new Linux-compatible games continue to be released as well.

Fedora Linux has been recognized as a "digital public good" by the Digital Public Goods Alliance (DPGA), a strategy group set up by UNICEF to promote sustainable development through open-source solutions that contribute to an equitable world.

The Raspberry Pi is an awesome little computer, whose capabilities won't stop increasing. As such, you should make sure that you have the best apps installed on it. Whether you're running Raspberry Pi OS (formerly known as Raspbian) some apps are unmissable.

The Java Development Kit (JDK) provides binaries, tools, and compilers for the development of Java applications. One helpful tool included is jconsole. To demonstrate, I will use the WildFly J2EE application server, which is part of the JBOSS open source application server project. First, I start up a standalone instance.

If hiding the top bar and side panel isn’t enough, and you want everything removed from your Ubuntu desktop, then you’d probably also like to get rid of those pesky icons on its surface. Read on to learn how you can hide desktop icons in Ubuntu.

Nick Rufflio had magic on his mind when he created this interactive ‘Goblet of Fire’ project, inspired by the fourth Harry Potter book of the same name. It’s powered by a Raspberry Pi Pico and does more than just replicate the classic goblet.

Nginx is a fast and popular web server that can be used as a reverse proxy and load balancer for your servers. In this tutorial, we will show you how to install nginx on Debian 11.

Application programming interfaces (APIs) are like fuel for digital transformation, enabling companies to develop applications and microservices quickly. DataTrucker.IO is a new, free and open source (Apache 2.0) no-code/less-code API backend that decreases the time required to build APIs.

A password is like a key to your house. In the online world, your password keeps your house of personal information safe, so a super strong password is like having a superhero in a fight of good vs. evil. In recognition of Cybersecurity Awareness month, we revisited our “Princesses make terrible passwords for Disney+ and every other account,” and took a look to see how fortified superhero passwords are in the fight against hackers and breaches.

Docker is a set of open platforms that provides OS-level virtualization for developing, shipping, and running applications. In this tutorial, you will learn how to install Docker on the Debian 11 Bullseye. Also, you will learn the basic usage of Docker for running containers and managing images.

Inkscape, the most used and loved tool of Fedora’s Design Team is not just a program for doing nice vector graphics. With vector graphics (in our case SVG) a lot more can be done. Many programs can import this format. Also, Inkscape can do a lot more than just graphics.

GitLab is a free and open-source DevOps platform that allows teams to iterate faster and innovate together. In this post, we will show you how to install GitLab with Nginx and Let's Encrypt SSL on Debian 11.

Computer programming, also known as coding for short, is not about which language you use. It's about developing programming logic and learning to think like a programmer. The language you start with should be the one that helps you the most in this endeavor. So you have to ask yourself the question: "What do you want to do as a programmer?"

Linux is an operating system used in everything from phones to cars and complex supercomputers, yet you can also use it to power your personal computer. The desktop may not be the space where you’re most likely to encounter Linux, but it’s more than worth your consideration.

A new kernel option was proposed today called "pkill_on_warn" that would kill all threads in a process if that process provoked a kernel warning. Currently when a process triggers a kernel warning there is no impact on that process by default. The Linux kernel does have a "panic_on_warn" option to cause a kernel panic when a warning happens, but pkill_on_warn would be less of an overkill and at least keep the system up and running.

If you've ever tried writing YAML, you may have been initially pleased with how apparently easy it looks. At first glance, the YAML that's often used for configuration files, Ansible playbooks, and flat-file databases looks more or less as intuitive as a shopping list. However, there's a lot of nuance in YAML's structure, and it conceals a dangerous secret: YAML is actually a highly precise, structured, and surprisingly strict language. The good news is that you only need to understand two things to know how YAML works.

In a previous article, I introduced Elasticsearch, Logstash, and Kibana (the ELK Stack) and the various components that make up this monitoring system. In this article, I'll look at how I use the ELK Stack to monitor my Nginx web server. This requires approximately 16GB of memory to operate.
