Step-by-step security guides for people who run their own WordPress site.

Make desktop automation practical, reliable, and cross-platform. Discover how to automate real-world applications, record interactions, and build maintainable GUI tests with Python.

Graphs are behind many of the problems software engineers face every day, from finding the shortest route to understanding complex networks. Practical Graph Theory shows you how to turn these problems into working solutions, with clear explanations, Python implementations and real-world examples that help you choose the right algorithm and understand why it works.

The wrong trading platform can cost you before you place your first trade. Zero commission doesn't mean zero cost. An advertised API doesn't mean your account can use it. Discover how to compare brokers, exchanges, forex, futures, crypto, trading software, market data, and true execution costs in this comprehensive 330-page guide—and build a trading setup that works on your terms.

Building AI-powered software takes more than plugging into an LLM. This book explores the engineering principles and architectural patterns behind reliable, secure and scalable AI systems. Learn how to move from prototypes to production with practical techniques that stand the test of time, even as models and frameworks evolve.

What really happens when a container starts? Go beyond Docker and explore the Linux kernel mechanisms that make containers work. Using Rust, you’ll build a container runtime from scratch, learning how namespaces, cgroups and other kernel primitives fit together to create a working system you can run, test and inspect yourself.

Building reliable AI agents takes more than connecting an LLM to a few tools. This book takes you inside the Cursor Agent SDK, showing you how to build, test and deploy agents that hold up in production. Learn the APIs, understand the architecture and turn agentic ideas into systems you can trust.

Las redes de computadoras forman parte de prácticamente todos los sistemas tecnológicos actuales, desde el acceso a Internet y las comunicaciones móviles hasta los servicios en la nube y los centros de datos, gran parte de la infraestructura digital moderna depende de la capacidad de transmitir información de forma eficiente y confiable. NETWORKING - Fundamentos, Arquitecturas y Despliegue Práctico, nace con el propósito de proporcionar una comprensión sólida de los fundamentos que hacen posible dicha comunicación. Más que centrarse en herramientas, fabricantes o tecnologías específicas, esta obra busca explicar los principios que permanecen constantes detrás de cualquier red, independientemente de su tamaño, complejidad o evolución tecnológica. El contenido ha sido organizado siguiendo una secuencia progresiva de aprendizaje. Cada tema se apoya en los conocimientos desarrollados anteriormente, permitiendo construir gradualmente una visión integral del funcionamiento de las redes de computadoras. A lo largo del recorrido se estudian las arquitecturas de comunicación, los modelos por capas, el flujo de información entre dispositivos, los mecanismos de encapsulación y los fundamentos físicos que permiten transportar datos a través de distintos medios de transmisión. Asimismo, se analizan conceptos esenciales como señales, codificación, modulación, ruido, capacidad de transmisión, espectro electromagnético y tecnologías inalámbricas modernas. Estos conocimientos constituyen la base necesaria para comprender posteriormente áreas más avanzadas relacionadas con administración de redes, infraestructura tecnológica, telecomunicaciones, computación en la nube y ciberseguridad.

What if you could make massive Mixture-of-Experts models smaller without retraining them from scratch? This book takes you from the fundamentals of expert pruning to practical implementation, covering proven methods, working code and real-world deployment challenges. Learn how to identify redundant experts, preserve model performance and build pruning solutions that work in production.

Fix common WordPress problems yourself: PHP updates, critical errors, white screens, database errors, missing form emails, server moves, and security notices. Each chapter shows where to look, how to judge what you see, and how to roll back safely.

Python was never built to be the fastest language, but the world it now powers demands more speed than ever. As JIT compilation pushes Python into new territory, old trade-offs are coming back into focus. What does it take to make a language faster without losing what made it popular in the first place?
