The only real way to celebrate the 30th anniversary of Linux is to write about Linux itself – not the agglomeration of software we know as a Linux distro, but the real Linux – the beating heart in the center of it all: the Linux kernel.

The D-Bus architecture creates a powerful channel for applications to communicate. A deeper understanding of D-Bus will help you with troubleshooting. Also, if you know how D-Bus works, you can customize the interaction of audio tools, text editors, and other apps to save time and simplify your life.

The classic vision of random access memory is just the beginning of the story. Modern hardware – and modern operating systems – manage memory in ways that old-school programmers could only have imagined. This month we take a look at virtual memory in Linux.

KDE's classic Plasma desktop can be as simple as you need it to be or as complicated as you want to make it. This month we explore the powerful Plasma 6 release that is making its way to your Linux distribution.

You don't need a fancy appliance to watch for intruders – just Suricata and a Raspberry Pi.

A crypto mining rig is built for math. Can an old rig find a second life solving science problems? That all depends on the problem. Also this month, we explore a few popular data analysis techniques and stir up some analysis of our own with the R programming language.

Experienced programmers are hard to find. Wouldn’t it be nice if subject matter experts and occasional coders could create their own applications? The low-code revolution is all about lowering the bar for programming knowledge. This month we show you some tools that let you assemble an application using easy graphical building blocks.

Everybody's talking about ChatGPT, and ChatGPT is talking about everything. Sure you can access the glib and versatile AI chatbot from a web interface, but think of the possibilities if you tune in from the Linux command line.

The worst case scenario is when the attackers know more than you do about your network. If you want to stay safe, learn the ways of the enemy. This month we give you a glimpse into the mind of the attacker, with a close look at privilege escalation, reverse shells, and other intrusion techniques.

Are you looking for a Linux to run on old hardware, or you just want a simpler system that is more responsive and less cluttered, how about a special Linux tailored for a special purpose, you’re sure to find inspiration in our look at small and specialty Linux systems.

On the Internet, you don’t have to wait for permission to speak to the world. Podcasting lets you connect with your audience no matter where they are. Whether you’re in it to build community, raise awareness about your skills, or just have some fun, the tools of the Linux environment make it easy to take your first steps.

This month we bring you snapshots from the quest for open data. A new generation of tools, policies, and advocates seeks to keep the data free, available, and in accessible formats.

Smart home solutions will save you time and energy – and, did I mention, you can amaze your friends. This month we show you how to take charge of your home environment with smart devices and open source automation software.

A sustainable world will need more sustainable programming. This month we tell you about some FOSS initiatives dedicated to energy efficiency, and we take a close look at some green coding techniques in Go.

Social media tools connect the world, bringing us the latest news and commentary from politicians, movie stars, community leaders, and remote friends. But the tracking and data mining of the commercial social media platforms has left many users searching for a better option. This month we dive down into the alternative universe for social media users: The Fediverse.

Think computers don't make mistakes? If you slip some doctored-up training samples into the mix, you can get a fancy machine-learning system to think a dog is a cat or a 1 is an 8 – and you can trigger this bad behavior through a hidden signal no one else will notice.

In theory, everyone could use the same backup tool, but the best way to build regular and systematic backups into your life is to find a solution that fits with your own habits and methods. This month, we preview some popular backup apps in the Linux space so you can find one that works for you.

What is the secret behind the recent explosion of computer art and fake videos? One neural network lies to another neural network...

Most Linux users know that this futuristic technology leverages the weird power of quantum mechanics. But how does it really work? What can I do with it? Are there tools available today that will help me experiment? This month we take a deep dive into quantum computing.

Machine learning remains shrouded in mystery even though it is now an integral part of our everyday world. This month we look behind the curtain at some popular techniques for supervised and unsupervised learning.

The most amazing thing about Linux is its flexibility. Linux systems run on the biggest computers in the world – and on many of the diminutive devices that populate your home environment. If you’ve always wondered how developers adapt Linux to run on tiny tech, you’ll appreciate this month’s stories on Buildroot and the Yocto project.

Behind the scenes, the cellular phone network has always been the preserve of highly specialized and proprietary equipment, but some recent innovations could be changing that. This month we explore the Open RAN specification, which could one day allow more of the mobile phone network to operate on off-the-shelf hardware.

Live boot was such an exciting idea 15 years ago – just carry a CD with you and boot from anywhere. But old-style boot CDs had some limitations. For one thing, they came in a fixed size. Then there was the problem that you couldn’t save anything. Today’s USB boot tools solve those problems plus offer a feature that no one even thought about back then: access to several boot images on a single stick.

If you are really serious about privacy, you’ll need to lean on more than your browser’s no tracking button. Those who need anonymity the most depend on the Tor network – a global project offering safe surfing even in surveillance states. We also look at Portmaster, an application firewall with some useful privacy features.

Twenty Years ago, everyone thought a gateway firewall was all you needed to stay safe from intruders, but recent history has told a different story. Today, the best advice is: Don’t trust anyone. Your internal network could be just as dangerous as the Internet.

Most people know you can save energy by changing to more efficient light bulbs, but did you know you can save energy with more efficient software? This month we examine the ongoing efforts to bring sustainability to the IT industry.

This month, we survey the state of encryption in Linux. We look beyond the basics to explore some of the tools and technologies that underpin the system of secrecy – and we show you what you need to know to ensure your privacy is airtight.

Biometrics got a boost recently with the arrival of Microsoft’s Hello technology. Now the open source world is catching up, with an innovative tool appropriately called Howdy. Facial authentication might not be ready for the CIA yet, but we’ll help you get started with Howdy and explore the possibilities of authenticating with a glance.

Fuzz Testing: Ever wonder how attackers discover those "carefully crafted input strings" that crash programs and surrender control? Welcome to the world of fuzz testing. We introduce you to the art of fuzzing and explore some leading fuzz testing techniques.

Eventually phone manufactures just give up on supporting old hardware. If you're not ready to abandon that hardware yourself, you might find a better alternative with LineageOS -- a free Android-based system that supports more than 300 phones, including many legacy models that are no longer supported by the vendor. We also explore PostmarketOS, a community-based Linux distribution that runs on several Android devices.

BSD Unix has been around longer than Linux, and it still has a loyal following within the Free Software community. This month we explore the benefits of a leading BSD variant from the viewpoint of a Linux user.
