Focus on Linux

Focus on Linux is a different way to look at Linux. A lot of Linux’s power is already built into the system itself, but many features stay hidden behind commands, configuration files, and concepts that are not always easy to understand. Because of this, people often depend on extra tools or complicated scripts, not because Linux lacks functionality, but because the core system feels difficult to approach.

In 2007, I switched entirely to Linux and have been using it every day ever since. Through years of working with Linux, both on the desktop and in system administration, I have learnt just how powerful the built-in tools and underlying concepts are. That practical experience forms the basis for these articles. I’ll show you how Linux works, why certain choices have been made, and how a good understanding of the system can help you solve problems independently.

These "Focus on Linux" articles help you better understand how Linux works under the hood. When you understand the logic behind the operating system, you can solve more problems using the tools that are already available. The software and utilities you do add will also integrate more naturally with the Linux ecosystem, instead of fighting against it.

These articles are not simple copy-and-paste tutorials. They focus more on the structure and ideas behind Linux. Every article explains one core concept step by step, not only how to use it, but also why Linux works this way and what becomes possible once you understand the system better.
