Spring Security 7 from the inside out. Trace requests through the filter chain, build a custom identity provider with Spring Authorization Server, secure reactive WebFlux services, and ship production hardened systems backed by JWT, OAuth2, OIDC, SAML2, WebAuthn, and zero trust microservice patterns. Built around CineTrack on Spring Boot 4 and Java 21. Written for engineers who already ship Spring Boot in production.

Postgres woke you up at three in the morning. Same code. Same hardware. Something changed. This book explains what changed and why, starting from the one idea that makes everything else legible: MVCC.

Navigate the architectural discontinuity of the Foundation Model Era with this comprehensive guide designed for professionals sitting at the intersection of technology and leadership. Master the intersection of technical precision and strategic oversight through the RACE framework, robust ethical principles, and the operational realities of MLOps. From the legal mandates of the EU AI Act to the emerging risks of agentic AI, this guide empowers you to lead AI transformation with intention and accountability.

Most books about ChatGPT explain the magic. This one shows you the math. Inside Large Language Models, Volume I takes a curious beginner from "what is an LLM" to a complete, trained GPT, with nothing more than high-school algebra, a working laptop, and a willingness to read carefully. Every formula is walked through by hand. Every line of code comes with a plain-English explanation. By the end you will have built, trained, and run your own transformer from scratch, and you will know exactly what is happening inside. No PhD or Data Science required. No prior machine learning needed. Just curiosity and a calculator.

Stop being a 'Syntax Coder' and start becoming a 'Diagnostic Architect' by mastering the hidden mental models of software failure. This book teaches you how to own every logical branch of your system and eliminate bugs before they even happen. Stop guessing and start diagnosing.

If you've ever wondered what the quantum computing stack actually looks like from top to bottom, this is the book.

如果惯性可以被编程会怎样？本书在 11 种编程语言中实现了 NKTg 定律 = f(x, v, m)，并通过真实 ESA 火星数据验证，误差仅为 0.208% —— 从 Python 到 Assembly，从人工智能到量子计算。

From the "original sin" of the stateless web to the looming threat of quantum-powered breaches, Something You Don't Know decodes the thousands of years of human ingenuity behind the login box. You will master modern engineering essentials like passkeys, Zero Trust architecture, and ML-KEM while learning to secure the next frontier: autonomous AI agents. It is the definitive guide for senior engineers who want to understand the physics of identity and build systems that are truly unshakeable.

Most developers treat Hibernate as a black box that turns objects into rows. This book opens the box, shows you exactly what happens inside, and teaches you how to make it work for you at scale.

Great data analysts are not defined by the software they use. They are defined by how they think about data.

Working with PySide6 should not depend on trial and error. This book replaces fragmented learning with a structured approach, combining in-depth explanations and dependable code examples that move you forward with confidence.

Exploring Java Libraries: A Developer’s Guide, Volume II is a hands-on guide to Java’s text-processing, desktop GUI, and accessibility libraries. Through practical examples, structured explanations, and real-world coding scenarios, it helps developers move beyond theory and master Java’s AWT, Swing, and java.text ecosystem.

Claude Code users routinely spend more on tokens than they expect, and cannot see where the money goes. Chapter 8 catalogues 48 diagnostic symptoms — what each one looks like, what it costs you, and what to change — with a fix where a fix exists, and an honest "unresolved" where none does yet. Chapter 7 puts before-and-after numbers against the changes, measured on the author's own unattended runs, and Chapter 9 collects the settings templates.

Learn how to build Kubernetes Operators from scratch using Kubebuilder, step by step. You will create real controllers, work with CRDs, and understand how reconciliation works in practice. By the end, you’ll know how to design, test, and run your custom operator.
