Linux is one of the best decisions you can make for your computer — but knowing where to start is the hard part. This guide walks you through everything: choosing a distribution, installing it, and using it confidently every day. It was written by Jay LaCroix of Learn Linux TV, for complete beginners. No prior experience required.

Whether you're upgrading, deploying, or simply exploring Ubuntu 26.04 LTS, this book is your essential guide to Canonical's most ambitious long-term support release. From installation and desktop features to security, performance, and enterprise deployment, it provides clear, practical coverage of everything you need to get the most from Ubuntu.

The Linux Virtual Filesystem is the abstraction that unifies every filesystem in Linux behind a single interface. This book explores its architecture, kernel implementation, and modern applications, giving system administrators, developers, and kernel engineers the knowledge to understand, troubleshoot, and extend the VFS.

Go from an empty cluster to a self-deploying GitOps pipeline, doing every step yourself: Applications, sync policy, hooks, RBAC, Helm, ApplicationSets, and a setup that ships every branch on push. You finish with a pipeline you can explain line by line, not a demo you watched run.

BGP security is more than a set of filters and policies. This book takes a practical, systems-level look at securing routing infrastructure, from RPKI and route filtering to monitoring, automation and incident response, with real configurations, code examples and lessons from incidents that have shaped how the Internet is secured.

A practical look at how the modern Internet edge really works. Explore DNS, BGP, TLS, HTTP/3 and the architecture behind content delivery, then apply that knowledge to building, securing and optimizing Cloudflare in production. No marketing fluff, just the engineering behind the edge.

Building fast LLM inference is about far more than turning the right knobs. This book takes you inside vLLM and the systems behind it, showing how memory, scheduling, GPUs and distributed serving shape real-world performance. Learn how to measure what matters, find bottlenecks and build inference infrastructure that scales without wasting money.

Infrastructure gets complicated fast. Mastering Terragrunt shows you how to bring order to growing Terraform and OpenTofu environments without adding unnecessary complexity. Learn practical patterns for managing multiple accounts, regions and teams, streamline deployments and build infrastructure that stays maintainable as your organization scales.

Go beyond basic Linux tuning and learn how performance really works under the hood. Explore kernel internals, hardware behavior, benchmarking and production optimization with practical tools, real trade-offs and copy-paste-ready examples. Build the skills to diagnose bottlenecks and solve performance problems with confidence.

Stop treating PostgreSQL like slightly broken MySQL and start using it the way it was designed.

Build your TCP/IP foundation through clear diagrams of layers, addressing, routing, transport, and end-to-end network communication.

Understand DNS through clear visual explanations of name resolution, zones, records, caching, security, and practical operations.

Learn Microsoft Intune through visual explanations of enrollment, device configuration, applications, compliance, and endpoint operations.

Build AI inference systems that run fast, use less memory and keep your data where it belongs. This hands-on guide walks you through model deployment, performance tuning, security and production engineering with practical code and real benchmarks. No cloud dependency, no surprise bills, just efficient AI systems you control.

This book is not just a Python course with a networking flavour or a networking course with a few scripts attached. You already know how routing converges, why VLANs leak, and what a half-open TCP session looks like on the wire. What this book adds is the ability to transform that knowledge into code that runs across hundreds of devices, reports accurately on its findings and never makes changes that cannot be undone.
