  • System 3: Towards Fluent Autonomy

    Hani Al-Shater

    What could a mighty billion-parameter reasoning machine learn from a camel trying to touch its ear with its tongue? From a cup of coffee? From deleting your entire codebase while you sleep? More than you’d think. And less than you’d hope. Today’s AI is brilliant structure without grounding—a hollow genius. We chase smarter models but ignore the architecture they need. This book is about building that missing layer: the trust chains and systems that turn raw intelligence into reliable autonomy. For builders ready to move beyond prompts.Watch agents solve unsolvable problems. Learn to think in trust chains. Start here.

  • Modern Networking

    Declan Moran

    Modern networks like the Internet — explained as simply as possible — but no simpler.

  • Be a Learning Machine

    Alberto Souza

    You’ll just need the Five Essential Elements of Learning Through five essential elements, you’ll gain the ability to learn anything deeply—no matter how complex the subject. These five pillars of effective learning will become lifelong tools, guiding you every time you set out to truly master new knowledge and retain it permanently. If you're ready to stop passively consuming information and start truly mastering it, this book is for you.

  • From Capone to Cray: Where Computers Really Came From

    Edward W. Barnard

    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.

  • Living Amongst the Wizards of Cray Research

    Edward W. Barnard

    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.

  • Nobody but Us: A History of Cray Research's Software and the Building of the World's Fastest Supercomputer

    Edward W. Barnard

    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.

  • Functional programming in Modern Java

    Jitin Kayyala

    Write code that you can understand without holding the entire system in your head. This book shows you how Java's modern functional features—records, sealed types, lambdas, streams—combine into a powerful approach to design. You'll learn: • How to eliminate race conditions without synchronized blocks • How to write tests that test business logic, not mock frameworks • How to compose complex behaviors from simple, reusable functions • How to manage deeply nested immutable data without boilerplate • How to adopt functional patterns incrementally in existing codebases Written for working developers. Filled with production-ready code examples.

  • Logic for Programmers

    Hillel Wayne

    Logic is the most important branch of math to software engineering. Knowing logic opens up a vast world of development techniques, from everyday tricks of the trade to exotic tools for cracking impossible tasks. This book teaches the basics of logic and nine special logic-powered techniques: property testing, decision tables, constraint solving, and more. Over 50 exercises are provided to help readers master the material. No prior math background required!

  • The Wizard's Lens: Learn to Think Like AI

    Edward W. Barnard

    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.

  • Corporate Sabotage Field Guide

    Stijn Dejongh

    The Corporate Sabotage Field Guide is a satirical field manual examining how organizations quietly undermine themselves from the inside. Framed like a classified dossier from the Office of Strategic Systemic Decay (OSSD), it catalogs familiar managerial practices — subtly weaponized to erode clarity, stall momentum, and sabotage culture under the guise of professionalism. Darkly humorous, uncomfortably accurate, and grounded in real systems behavior, it’s written for those who recognize that dysfunction often wears a lanyard.

  • Ishi: The Discipline of Determined Intent

    Gareth Holebrook

    Capable people drift into failure through accumulated lapses in attention. By the time collapse becomes visible, erosion has been active for years. Ishi is the discipline that interrupts drift before collapse forces correction.

  • The Effective Software Engineer

    Stefan Ellersdorfer

    What makes a software engineer truly effective? Beyond writing code, effectiveness comes from ethics, sustainable practices, collaboration, and the courage to adapt. The Effective Software Engineer guides you from clean coding habits to organizational empowerment, bridging the gap between developers and leaders.

  • Residues: Time, Change, and Uncertainty in Software Architecture.

    Barry M O’Reilly

    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.

  • The Architect’s Paradox

    Barry O’Reilly

    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?”.
