Storage

A hands-on guide to building a complete FAT12 filesystem driver in C — from reading your first sector to running code in QEMU. Write everything yourself, boot sector to cat command.

Go beyond the NTFS API and learn how the filesystem really works. This book explains NTFS from its on-disk structures to a complete working implementation, giving you the knowledge to understand and build one of the world's most sophisticated filesystems.

The Linux ext4 filesystem is one of the world's most widely used filesystems, but its internal design is often difficult to understand. This book provides a practical, implementation-focused guide to ext4, covering its on-disk structures, algorithms, and core subsystems with detailed explanations, production-quality code, and references to the Linux kernel source.

Build OpenStack with confidence, from your first deployment to production at scale. This hands-on guide walks you through planning, configuration, security, daily operations and troubleshooting with practical examples and proven techniques. A dependable resource for admins, DevOps engineers and cloud architects.

Build smarter AI applications with Redis at the core. This practical guide shows you how to use vector search, RAG, semantic caching, agent memory and real-time inference to create fast, scalable systems. With runnable Python examples throughout, you’ll learn how to take AI projects from prototype to production.

Go beyond the basics and learn how to get the most from RocksDB. This practical guide explains the architecture behind its speed, shows how to tune it for real workloads and helps you solve performance issues with confidence. Packed with code examples and production-focused advice, it is built for developers who need storage that scales.

DuckDB has changed how people work with data by bringing fast analytical queries to a lightweight embedded database. Whether you are exploring Parquet files, building data pipelines or embedding analytics into your application, this handbook shows you how to get the most out of DuckDB with practical examples and real-world techniques.

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

Slow SQL queries waste time, increase costs, and limit scalability. Mastering SQL Performance Optimization teaches you how to analyze execution plans, optimize queries and indexes, and solve real-world performance bottlenecks across today's leading database platforms.

This book is all about having a deep understanding of every configuration decision, every index design, every backup policy, and every failover drill. All the recipes in this book are for real-life tasks that you'd actually do, with all the exact commands and configurations that work on a production linux server running MySQL.

Hyperscale Data Center Management reveals the architecture, operations, and strategy behind the world’s largest computing facilities. Discover how power, cooling, and network fabrics are engineered to serve billions; how automation and reliability principles keep services running through constant hardware failure; and how sustainability and economics shape every decision. From foundational definitions to the new demands of AI and GPU workloads, this is the complete guide to managing infrastructure that never sleeps. Essential reading for architects, operators, and leaders building for the future.

Evolve from building static applications to architecting sophisticated cognitive systems. Master the Microsoft Semantic Kernel to bridge deterministic C# code with LLM reasoning. Build autonomous agents that plan, execute, and adapt using advanced enterprise patterns. Stop writing scripts and start engineering the future of intelligent .NET software.

Transform your data layer into an intelligent brain using EF Core and C#. Bridge the gap between traditional SQL and Vector Databases to power RAG and semantic search. Master secure, multi-tenant architectures that provide your AI applications with memory and context. Stop building prototypes and start architecting production-ready intelligent systems today.

This series of test-driven small coding puzzles lets you code a database from scratch (no dependencies).We'll cover KV storage engines, LSM-Tree indexes, SQL, concurrent transactions, ACID, etc.
