As applications become more distributed, traditional monitoring and security tools are failing to keep pace. This article explores how eBPF, when utilized by the graduated CNCF Cilium and its sub-project Tetragon, combined with Software Bills of Materials (SBOMs), can provide insights and a security feedback loop for modern systems. We’ll create a container image and its SBOM. We’ll then launch it, simulate a breach, and see how our eBPF-based setup with Tetragon captures the issue. This will show how the SBOM can be used to debug and understand the incident.

As a Linux SysAdmin working in a production environment, your daily routine is all about keeping systems stable, secure, and performing at their best. From troubleshooting issues to monitoring resources and ensuring uptime, you wear many hats, and time is always of the essence.

While Linux offers thousands of commands, not all of them are part of your day-to-day toolbox. However, there’s a core set of powerful, reliable commands that you’ll find yourself using every single day, often multiple times.

In this article, I’ll walk you through the 20 most essential Linux commands every system administrator should master. These aren’t just commands, they’re your go-to tools for monitoring performance, managing logs, controlling services, debugging problems, and much more.

Managing Linux servers daily can be fun and stressful, especially when you’re dealing with unexpected downtimes or service failures. One thing I’ve learned in my 15+ years as a Linux sysadmin is this: Prevention is better than a cure.

You don’t want to wait for users to report issues. As a sysadmin, your goal should be to detect problems before they affect users or production workloads.

That’s why I always recommend automating daily health checks for your system. If you know ahead of time that disk space is running low or a service has failed, you can fix it before users start shouting.

Linux users have always preferred AMD over Intel – at least, this is what I’ve seen and read since the beginning of my Linux journey in 2014. TUXEDO Computers confirms once again that it is listening to feedback, as Linux users continue arguing against Intel and demanding more AMD hardware. Therefore, the German-based hardware manufacturer has unveiled the TUXEDO InfinityBook Pro 14 Gen10 Linux Laptop with more red power! So, what does this new generation of elegant Linux laptops offer?

In this blog post, we will explain how to install Java 21 on Debian 13 OS in detail. Java is a high-level, object-oriented programming language with a syntax similar to C and C++. It was developed to let programmers write code in Java once and compile it everywhere, making it compatible with multiple platforms without recompiling. Java comes in three different editions: JRE, JDK, and OpenJDK.

JRE stands for Java Runtime Environment. It is a software layer that runs on top of a server operating system and provides class libraries and other resources.

JDK stands for Java Development Kit, a distribution of Java technology by Oracle Corporation. It implements the Java Language Specification and Java Virtual Machine and provides a standard Java Application Programming Interface edition.

OpenJDK or Open Java Development Kit is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

Installing Java 21 on Debian 13 is straightforward and may take up to 15 minutes. Let’s get started!

Backups are like insurance; you don’t need them every day, but when disaster strikes, such as accidental file deletion, a disk failure, or a ransomware attack, it’s enough to ruin everything if you’re not prepared. That’s where smart backup planning comes in.

In this guide, I’ll show you how to schedule incremental backups using rsync and cron. I’ll explain what incremental backups are, how rsync works under the hood, and how to automate the whole process with cron.
