OPERATING SYSTEMS
Operating systems are the foundation every developer, sysadmin, and IT professional builds on — from the Linux servers that run 96% of the world's top one million websites to the Windows desktops and servers that power most enterprise environments. This category brings together every Dargslan eBook that teaches you how to install, configure, harden, troubleshoot, and operate the major operating systems used in production today.
Inside you will find dedicated subcategories for Linux (the dominant server OS, with deep coverage of Ubuntu, Debian, RHEL, Rocky, AlmaLinux, Fedora, and Arch), Windows (desktop and Windows Server, including Active Directory and Group Policy), and Cross-Platform topics that span both worlds — like SSH, scripting, networking, and DevOps tooling. Each subcategory is curated so you can move from absolute beginner to confident professional without jumping between dozens of disconnected free tutorials.
Whether you are a career switcher heading into DevOps or cloud engineering, a junior developer who needs to deploy your own code to a Linux server, a Windows admin moving toward hybrid cloud, or a security professional hardening fleets of mixed servers, the operating-systems category is where you start. Every book is hands-on, command-line first, and written for the way real production systems actually behave — not the simplified examples you find in academic textbooks.
The most popular learning paths in this category are: (1) Linux Essentials → Linux Administration → Linux Security for the server-side track, (2) Windows Server → PowerShell → Active Directory for the Windows track, and (3) the cross-platform fundamentals — SSH, networking, shell scripting — that every IT professional eventually needs regardless of which OS they specialize in.
