Featured Leanpub Book

Docker for React.js developers

Kristiyan Velkov

The "It Works on My Machine" Excuse Ends Today. Understand Docker. Ship with Confidence. Own Production.

This book is written for front-end developers who are tired of using Docker without truly understanding it. Instead of abstract theory or backend-centric explanations, it teaches Docker in a clear, practical way—aligned with how front-end engineers think and how real front-end applications are built and shipped.

You’ll work with a real GitHub repository, follow real production workflows, and learn how to build, run, and deploy a React.js application using Docker—ending with a full deployment to Amazon EC2. Every step is explained with purpose, so you understand not just what to do, but why it works.

By the end of the book, Docker will no longer feel like a black box. You’ll know how to create reliable builds, debug problems with confidence, and take ownership of your production environment as a front-end developer.

If you want to stop guessing, stop copying commands, and finally ship front-end applications with confidence—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.

  • 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?”.

  • System 3: Towards Fluent Autonomy

    Hani Al-Shater

    What could a billion-parameter reasoning machine learn from a camel trying to lick its own ear?More than you'd think. Less than you'd hope.System 3 is the journey between those two answers. It argues that we are obsessed with making AI models "think harder" (System 2), when we actually need them to "check better" (System 3).This book isn't just theory. It documents real-world experiments in agent architecture, including: * The Epistemic Experiment: A head-to-head battle on SWE-bench Verified where adding a "trust stack" to an agent reduced code patch size by 57% compared to the baseline. * The Algorithm Vortex: How an autonomous agent, using zero framework code, researched and invented a "Diagonal Layering" strategy for circle packing that matched DeepMind's AlphaEvolve benchmark. * Vibe Coding & Deep Mode: Moving beyond "copy-paste" coding to an architecture where agents research, evaluate, and verify their own work.Written for engineers, researchers, and anyone tired of the hype, System 3 offers a blueprint for building agents that are fluent, grounded, and trustworthy.
