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.
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.
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?”.
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.
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.

If you're ready to stop passively consuming information and start truly mastering it, this book is for you.
Mastering Modern Time Series Forecasting is your all-in-one guide to building real-world forecasting systems that work — from classical stats to deep learning and beyond. Whether you're modeling retail demand or energy loads, this book gives you the tools, intuition, and code to go from zero to production. You'll cover ARIMA, ML, deep nets, transformers, and even the rise of FTSMs (Foundational Time Series Models). Written by a practitioner who’s built forecasting solutions for multibillion-dollar businesses, this is the hands-on, honest guide every data scientist, analyst, or forecaster needs.

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.
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.
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 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.
