Data Engineering

We'll be working on a platform made up of seventy-nine recipes together. It starts off as a simple task, printing a line, but by the last chapter it covers extraction, warehousing, containers, machine learning and incident response. You can't just throw away examples in your work, and you shouldn't be doing that in your examples either. You don't need to be an Airflow expert to get started. What you're really learning here isn't a tool. It's all about making sure work is repeatable, observable and safe to rerun.

Build real-time data systems that can keep up with the demands of production. Streaming at Scale takes you under the hood of Apache Flink, covering state, event time, exactly-once processing, performance, Kubernetes and more. With runnable examples and practical lessons, it shows how to build systems that are fast, reliable and ready to scale.

DuckDB is changing how developers think about analytics. This practical guide takes you from its architecture and SQL capabilities to performance tuning, cloud storage and production deployments. Learn how DuckDB works, where it shines and how to build fast, flexible analytical systems around it.

Passage 1 — Chapter 9, "Data Security": a definition that sets the technical tone immediately A hacker is someone skilled at finding undocumented techniques and loopholes in the tangled architecture of complex information systems; by intent, a "white hat" looks for such loopholes in order to strengthen the system, while a "black hat" uses them to steal or to cause harm. Passage 2 — Chapter 14, "Metadata Management": an image that explains the whole topic in one paragraph A vivid illustration: an enormous document archive with no index at all — the shelves are full, but there is no way to find out what sits on them short of examining every single box by hand. That is exactly what an organization looks like when it has piled up mountains of data without also taking care of metadata — the information physically exists, but it cannot be used systematically, since the only way to find what is needed is to already know where it sits. Knowledge about data is always scattered: in a large company, one person carries the structure of a single database in their head, another the rules of a single integration, a third the history of a single metric, and nobody holds the complete picture. Passage 3 — Chapter 15, "Data Quality Management, Part 1": why "quality" is an empty word without a yardstick A postal address missing an apartment number works perfectly well for a mass catalog mailing and works terribly for a courier who has to knock on the right door — and in both cases it is the very same row in the very same database, only the yardstick applied to it differs. Passage 4 — Chapter 21, "Organizational Change Management": the book's closing summary Data governance, the coordinating hub of eleven knowledge areas this book opened with, stays an empty frame until specific people come to value the new way of working with data through their own experience — which is exactly why a book that began by mapping the circle of disciplines around that hub fittingly closes not with another technique or tool, but with a conversation about the person without whose deliberate participation no structure ever becomes a practice.

A comprehensive technical guide to Python-driven cloud architecture, infrastructure automation, serverless engineering, security, distributed systems, and large-scale AWS operations.Modern cloud infrastructure is more than a collection of virtual machines and managed services. It is a programmable environment in which networking, identity, compute, storage, databases, messaging, and observability must work together as a coherent system. Building reliable cloud platforms requires software engineering discipline, automation, security controls, and a detailed understanding of how these services interact.Mastering AWS: Advanced Python Engineering is a 100-chapter technical reference for senior software engineers, DevOps specialists, cloud architects, platform engineers, and developers seeking to build sophisticated AWS environments with Python.

Passage 1 — Chapter 8, "Data Quality: Can the Board Trust Its Own Numbers": what bad data actually costs a leader Business folklore has long carried a caustic image: a machine that hands back garbage on the way out once it has been fed garbage on the way in — the old saying that poor input inevitably produces poor output, which this book already invoked earlier to explain why data quality went neglected for so long. It is worth taking that image seriously here and translating it into terms a leader can act on: exactly how much the input garbage costs a company, and by what test to recognize the moment a figure on a board slide becomes too risky to trust. Passage 2 — Chapter 9, "Analytics for Business: Data Warehousing and Metadata": a scene that stays with the reader Picture a board meeting: a single figure sits on the screen — quarterly revenue, say, or the share of customers who defected to a competitor — and one of the directors simply asks where that number came from. The pause that falls over the room while someone runs off to fetch an explanation from whoever put the report together says more about the state of trust in a company's analytics than any presentation ever could. Passage 3 — Chapter 11, "Data Management Maturity Assessment": maturity as something measured, not graded The practical conclusion for a leader is this: a maturity rung is not a verdict of "good" or "bad" — it measures how controlled and predictable a company's data work actually is. The higher the rung, the fewer surprises, and the more accurately a leader can forecast the consequences of decisions built on that data. Passage 4 — Chapter 13, "Managing Organizational Change in Data Management": the book's closing argument Taken together, the material across all thirteen chapters gives a leader a coherent view of data — from understanding it as a business asset to a concrete toolkit for leading organizational change. The architectural choices, technological infrastructure, and quality-control procedures examined earlier remain unrealized potential until someone at the most senior level of management personally takes on the work of carrying people through resistance and turning that potential into the company's everyday working habit.

Forecasting is changing fast. This practical guide takes you from ARIMA and exponential smoothing to Transformers, PatchTST and foundation models like Chronos and TimesFM. With clear explanations, hands-on Python examples and an honest look at what works and what fails, you’ll learn how to build forecasting systems that hold up in the real world.

Android Debug Bridge (ADB) is much more than a command for installing applications or opening a shell. It is an interface to Android's debugging, diagnostics, package management, performance analysis, device automation, and system-inspection capabilities. Mastering Advanced ADB Command Line is an 80-chapter technical reference for professionals who need to work beyond basic commands

An advanced technical reference to Qiskit architecture, IBM Quantum hardware, pulse-level control, error mitigation, quantum algorithms, and scalable quantum-classical computing.Quantum computing is moving beyond the construction of theoretical circuits toward the practical challenge of executing workloads on noisy, hardware-constrained quantum processors. This transition requires a detailed understanding of quantum algorithms, compiler architecture, device topology, calibration, error mitigation, and the classical infrastructure that supports quantum execution. Advanced IBM Quantum Computing and Qiskit Architecture is an 80-chapter technical reference exploring the engineering principles behind modern Qiskit development and IBM Quantum systems. It connects quantum programming abstractions with hardware-aware compilation, runtime execution, performance analysis, and the challenges of building reproducible quantum-classical workflows.
