Books

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

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.

Ready to take your infrastructure skills to the next level? Mastering Pulumi shows you how to build, deploy and manage real-world infrastructure across multiple clouds using familiar programming languages. From your first project to complex enterprise platforms, discover practical techniques and proven patterns to make infrastructure more reliable, secure and easier to maintain.

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.

What if a 125B-parameter AI model could run locally on a gaming GPU with just 12 GB of VRAM? Strata makes it possible. This book takes you inside the techniques that make it work, from MoE sparsity and memory tiers to PCIe pipelining and speculative decoding, then shows you how to install, tune and troubleshoot it yourself.

Inference engineering is now its own discipline, with unique challenges around speed, cost, reliability and scale. This practical guide takes you from core concepts to production systems, showing how modern inference architectures work, how to optimize them and how to make better engineering decisions through measurement and trade-off analysis.

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.

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.

Go beyond the basics of Tor and learn how to build private, resilient services on the dark web. From onion routing and v3 onion services to real-world threats and secure deployment, this book gives you the technical knowledge and practical skills to host privacy-critical services without exposing where they live.

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.

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.
