Operational Tempo Under Drone Dominance by Alessio Faccia
English | November 22, 2025 | ISBN: N/A | ASIN: B0DCG42DDH | 135 pages | EPUB | 1.83 Mb
Operational tempo in drone-saturated conflict follows a rhythm driven by timing pressure rather than force size or weapon range. Modern units face continuous observation, rapid sensor refresh, and short engagement windows. This book analyses how timing governs every action on the field, from detection and movement to fire support, logistics, electronic warfare, and command decisions. Classic doctrine assumed predictable cycles built on staggered reconnaissance, slower communications, and human-paced judgement. Drone dominance removes those buffers. Feeds update many times per minute, networks crowd under heavy imagery flow, and crews must act before the next frame reshapes the picture.

Operational Research in War and Peace : The British Experience from the 1930s to 1970 By Maurice W. Kirby
2003 | 400 Pages | ISBN: 1860942970 | PDF | 25 MB
This invaluable book provides an account of Operational Research in Britain, the country of its inception, from the late 1930s to 1970. Originating in response to the country's air defence needs against the Luftwaffe, Operational Research had outstanding achievements as part of the 'secret war' against Nazi Germany. After 1945, the discipline began to be adopted in an increasing range of industries and services. In the 1960s - by which time it was being incorporated in to university curricula - the discipline began to penetrate into civil government departments. The history of Operational Research provides unique insights into the conduct of modern warfare, the professionalisation of business management and the modernisation of the civil service. The chronological coverage, from the late 1930s to 1970, coincides with 'golden age' of Operational Research, when the discipline was presented as a means of achieving optimum solutions to complex managerial problems. The book will be of interest to military and business historians, as well as to historians of public administration and higher education.

Barnes Carr, "Operation Whisper: The Capture of Soviet Spies Morris and Lona Cohen"
English | ISBN: 1611688094 | 2016 | 338 pages | MOBI | 10 MB
Meet Morris and Lona Cohen, an ordinary-seeming couple living on a teacher's salary in a nondescript building on the East Side of New York City. On a hot afternoon in the autumn of 1950, a trusted colleague knocked at their door, held up a finger for silence, then began scribbling a note: Go now. Leave the lights on, walk out, don't look back. Born and raised in the Bronx and recruited to play football at Mississippi State, Morris Cohen fought for the Loyalists in the Spanish Civil War and with the U.S. Army in World War II. He and his wife, Lona, were as American as football and fried chicken, but for one detail: they'd spent their entire adult lives stealing American military secrets for the Soviet Union. And not just any military secrets, but a complete working plan of the first atomic bomb, smuggled direct from Los Alamos to their Soviet handler in New York. Their associates Julius and Ethel Rosenberg, who accomplished far less, had just been arrested, and the prosecutor wanted the death penalty. Did the Cohens wish to face the same fate? Federal agents were in the neighborhood, knocking on doors, getting close. So get out. Take nothing. Tell no one. In Operation Whisper, Barnes Carr tells the full, true story of the most effective Soviet spy couple in America, a pair who vanished under the FBI's nose only to turn up posing as rare book dealers in London, where they continued their atomic spying. The Cohens were talented, dedicated, worldly spies―an urbane, jet-set couple loyal to their service and their friends, and very good at their work. Most people they met seemed to think they represented the best of America. The Soviets certainly thought so.

Operating Modern Data Systems: Architectural Control, Reliability, and Evolution in Production Distributed Systems
English | December 28, 2025 | ASIN: B0GCXF2M9D | 462 pages | EPUB (True) | 6.36 MB
Operational architecture for long-lived data systems. Modern data systems rarely fail because of broken code. They fail because architectural intent erodes under time, pressure, and continuous change. Operating Modern Data Systems is a deep, architecture-first examination of what happens after systems leave the whiteboard and enter production. It reframes operations as an architectural discipline-where guarantees are defended or lost, authority is exercised under stress, and reliability is proven over years rather than releases. This book is not about tools, dashboards, or incident checklists. It focuses instead on the structural forces that shape real production systems: failure as a normal condition, time and ordering ambiguity, load and pressure propagation, migration risk, cost as a signal, security as operational trust, and the human and organizational realities embedded in every system. Written for experienced practitioners, the book develops architectural judgment rather than prescribing solutions. It examines how systems drift, how meaning degrades silently, and how design decisions are continuously rewritten through operational action. What This Book Covers Why correct designs still fail after deployment How operational shortcuts quietly become architectural commitments Reliability as preserved meaning-not just uptime Failure as a continuous condition, not an exceptional event Time, ordering, and partial truth in distributed systems Recovery, migration, and change as extended failure modes Load, pressure, backpressure, and containment Observability as the ability to explain behavior Cost, security, and governance as architectural signals Human judgment and organizational structure as part of the system How systems age-and what allows architecture to hold over time What Makes This Book Different Operations treated as architecture Production behavior, failure, and recovery are examined as structural concerns, not operational afterthoughts. Decision- and consequence-focused The book emphasizes how choices accumulate, constrain future change, and shape long-term reliability. Tool-agnostic and durable Concepts are designed to remain relevant as platforms, frameworks, and AI systems evolve. Reliability redefined Availability alone is not success. Reliability is the preservation of meaning, guarantees, and trust under stress. Written for the AI era without hype The book situates modern data and AI-driven systems within the same architectural forces, showing where automation amplifies risk and responsibility. Who This Book Is For This book is written for: Software engineers operating backend and platform systems Data engineers responsible for production pipelines and storage Senior, staff, and principal engineers shaping system architecture Architects and technical leaders accountable for long-term reliability Practitioners working with distributed data systems and AI platforms It assumes familiarity with production systems and distributed environments. Who This Book Is Not For Beginners seeking introductions or tutorials Readers looking for step-by-step guides or tool-specific instructions Those expecting quick fixes, patterns, or checklists Order now to develop architectural judgment for systems that must endure pressure, change, and time.
