Java has changed. Have your patterns kept up?The Gang of Four wrote their landmark patterns in 1994 — when Java didn't exist, generics were a decade away, and "concurrency" meant carefully managing a handful of platform threads. Thirty years later, Java 21 through 25 has transformed the language: records replace boilerplate classes, sealed interfaces model closed type hierarchies with compiler enforcement, pattern matching eliminates entire categories of unsafe casting, and virtual threads make a million concurrent tasks not just possible but routine.Modern Java Design Patterns bridges that gap. Every classic pattern is shown first in its original form, then systematically rebuilt with the language features that exist today. The result is code that is shorter, safer, more expressive, and immediately recognisable to any team working on a modern Java codebase.
What happens when a quality management graduate discovers that the factory floor doesn't care about her degree? A story about standards, survival, and the real cost of poor quality.
En 1974, una señal salió de la Tierra con dirección fija. No buscaba responder nada. Buscaba decir que estábamos aquí. El mensaje de Arecibo fue breve, matemático y silencioso. Pero su alcance todavía continúa.
Un mensaje viajó hacia el espacio profundo. No contenía palabras. No tenía voz. Solo matemática, símbolos y una estructura diseñada para sobrevivir al vacío. Fue enviado desde Arecibo en 1974. Lo que parecía un gesto científico terminó convirtiéndose en una de las preguntas más persistentes de la astronomía moderna.

¿Qué hace que el dinero sea dinero? ¿Cómo es posible que los bancos creen dinero de la nada? ¿Por qué la inflación destruye los ahorros de unos y beneficia a otros? Este libro responde a las preguntas que nadie te explicó.

What are KPIs? - everyone might think they know but what are they really?And what are these OKRs that look a bit like KPIs?Should I use them both? How should I combine them?Numbers, numbers, numbers, we might be rational but should we apply them everywhere?If everything is a number then what is the meaning of business and work?
You don't need another "intro to LLMs" tutorial. You need patterns—proven architectural blueprints that tell you exactly when to use RAG vs. fine-tuning, how to build agents that don't spiral, and why your retrieval pipeline returns garbage. This book gives you 29 of them, with architecture diagrams and working Python code. Free. No fluff. No vendor lock-in.
The era of cloud-only AI is over. Transition from calling remote APIs to building on-device brains using Gemini Nano, local LLMs, and private RAG pipelines.Master the hardware orchestration and Kotlin architecture needed for privacy, zero latency, and production-grade mobile intelligence.Stop being just a developer—become an Android AI Engineer and lead the 2026 mobile revolution today!
Most blockchain books teach the theory. This one walks you through building a complete Bitcoin-style blockchain in Rust, end to end — cryptography, consensus, networking, persistence, REST API, desktop wallets, and Kubernetes deployment.
One of the key aspects of innovation is its ability to adapt and evolve. What may have been groundbreaking technology a few decades ago may now seem obsolete. This constant cycle of improvement and adaptation is what drives innovation forward, pushing us to think outside the box and find new ways to solve problems. Moreover, innovation is not limited to just technology. It can also be seen in other fields such as medicine, transportation, and agriculture. From life-saving medical treatments to more sustainable farming practices, innovation has the power to create positive change in various industries.
