Linux

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.

Ever wondered what really happens inside the Linux kernel when a program runs? Go beyond the surface and explore the code, data structures and hardware mechanisms that make Linux work. From system calls to CPU instructions, this book takes you deep into the kernel’s inner workings, giving experienced programmers a closer look at the system they rely on every day.

From the Linux basics to advanced development workflows, this practical guide shows you how to turn Linux into a powerful software development environment. Learn the command line, work with popular programming languages, use containers and CI/CD, debug and profile applications and build skills you can use every day.

Build your Linux foundation through visual explanations of processes, files, permissions, networking, storage, and system operations.

Aren't you curious about Linux? Do you want to try it out and step into its vast world, but prefer to learn it in a way that is smooth rather than academic?

Learn Bash the way it should be taught: by building one real, tested backup tool — not toy examples — one Git commit at a time.

Ever wondered what really happens inside a terminal? Go beyond the command line and explore the systems that make modern terminals work. From TTY and PTY internals to Unicode, GPU-accelerated rendering and terminal protocols, this book takes you under the hood and brings it all together with a fully working terminal emulator built in Rust.

This book teaches you to build and run one application together. We will be creating Azure Linux node pools with Bicep, debugging nodes with tdnf, shipping slim images, securing pods with workload identity, scaling with KEDA, patching without fear, monitoring with KQL, delivering through GitOps and even training a model on a GPU.Instead of a mysterious layer beneath your containers, it becomes a platform you understand, inspect and trust.

In this 2nd edition, I'm going to be working with you on a single app called OrderDesk. We'll build its inventory, roles and secrets, and then we'll patch its servers, provision its cloud resources and deploy it to Kubernetes. Later, we'll watch it with Prometheus, heal it with Event-Driven Ansible and diagnose its failures with playbooks that collect evidence in seconds. Then, in the last few chapters, we'll start inviting AI agents through tools and MCP servers, while approvals and check mode make sure that everyone keeps control of the decisions. You don't need to be a pro programmer to follow along.

Your own AI assistant at home: private, local, and safe. Ten step-by-step chapters, each one tested on a fresh machine before publishing.

HAProxy Essentials is a practical guide to building, running and troubleshooting HAProxy in production. From core concepts to advanced architecture, it explains how the pieces fit together and what can go wrong. Based on HAProxy 3.4 LTS, with clear notes on 2.8 and Enterprise-specific features.

Self-hosting from home sounds simple until CGNAT, changing IPv6 prefixes and double NAT get in the way. This book shows you how to build Linux infrastructure that actually works on the real Internet, with practical architectures, working configurations and troubleshooting techniques that help you understand what is really happening to your packets.

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.

A Comprehensive Engineering Guide to Linux Kernel Graphics Architecture, DRM/KMS, GPU Memory Management, Command Execution, Scheduling, Virtualization, and Driver Development...

Build Linux from the ground up and see what really happens under the hood. From firmware and bootloader to kernel, libc, init, networking and security, this book strips the system down to its essentials while explaining why every piece exists, what depends on it and how far you can push minimalism.
