Residuality Theory is a new way to think about the design of software systems that explains why we experience design the way we do, why certain things seem to work only sporadically, and why certain architects get it right so often regardless of which tools they use. A new, scientific approach is defined that fuses Software Engineering, Complexity Science, and Philosophy to produce an entirely new way to think about how to design software. The result is a theoretical base that allows architecture to finally become its own discipline.
An introduction to philosophy for software engineers and architects that will help them understand their design process. This book helps to answer the question “Why are we like this?”.

Where did modern computing really come from? Not from garages in California, but from bootleggers, codebreakers, and Cold War air‑defense engineers. This book reveals a lineage that almost no computing history traces: Prohibition‑era encrypted radio → Elizebeth & William Friedman → OP‑20‑G → MIT Whirlwind → SAGE → Engineering Research Associates → Control Data → Seymour Cray. From Capone’s smugglers to Cray’s supercomputers, the story of U.S. large‑scale computing is a straight line, just one that has been forgotten. Combining deep historical research with firsthand experience from the CRAY‑1 era, this book shows how cryptology, radar, and national‑security urgency created the machines that defined modern computing. If you think you know the origins of the computer revolution, this book will change your mind.
What does it really mean to work among “wizards”?At Cray Research, the machines were legendary, but the culture behind them mattered just as much. Living Amongst the Wizards of Cray Research offers an insider’s view of a place where problems resisted clean explanations, debugging was a way of life, and expertise emerged from sustained exposure to failure, uncertainty, and responsibility.Rather than celebrating genius or heroics, the book focuses on method: how engineers learned to reason about complex systems, argue ideas into existence, use humor as pressure relief, and recognize patterns long before tools could make them obvious. The stories are grounded, sometimes uncomfortable, and often quietly funny.This is not a nostalgia piece or a technical manual. It is a reflection on how rare expertise is formed, how demanding cultures endure, and what it actually feels like to live inside work that cannot be simplified.
A Cray Research veteran narrates how pioneers handled overwhelming complexity: pattern recognition anticipating Midway, systems thinking inventing magnetic core memory. Experience from one domain, applied in a new way, shaped supercomputing.
Learn to think like AI through a working LLM you build yourself. Battle-tested systems thinking from Cray Research applied to modern AI. Accomplish what others consider impossible.
The Corporate Sabotage Field Guide is a satirical manual for embedded operatives in the Office of Strategic Systemic Decay (OSSD). Framed like a classified black-ops dossier, it catalogs subversive managerial tactics designed to erode clarity, stall momentum, and sabotage culture — all under the guise of professionalism. Equal parts dark humor and painfully accurate critique, it’s a field manual for those who know that sometimes, dysfunction wears a lanyard.
