  8. Agentic Programming
    From Prompts to Production: A Path to Al Fluency
    Jerod W. Wilkerson

    The most important impact of AI on software development isn't that it writes code faster — it's that it changes what you can delegate. Agentic Programming is a practical roadmap for climbing the AI Fluency Ladder: from prompting to agentic workflows, verified execution, and ultimately autonomous software development.

  9. Beginning Game Programming with Go
    A hands-on, project-based guide to 2D game development in Go
    Luigi Vanacore

    Build a game from scratch in Go, no engine magic, just code you understand. You'll create Gopher Survivor, a Vampire Survivors–style action game, one concept per chapter: enemies, weapons, XP and level-ups, particles, a state machine, and a build you can ship.

  10. The Hundred-Page Language Models Book
    hands-on with PyTorch
    Andriy Burkov

    Master language models through mathematics, illustrations, and code―and build your own from scratch!

  12. CISSP: The Last Mile
    Your guide to the finish line
    Pete Zerger

    The book covers every topic in the latest CISSP exam syllabus, organized in a format that makes it easy to drill down on specific exam domains and concepts at-a-glance, making it an essential exam resource for anyone who aims to prepare for the exam without wasting time or money.

  13. The Sovereign Engineer
    AI Literacy for Software Professionals
    Russ Miles

    AI is an amplifier. It magnifies whatever engineering discipline — or lack of it — already exists, which means the bottleneck was never AI's capability; it is the collaboration space you design around it. This book is a six-level progression from early AI panic to sovereign engineering: the discipline of designing the environment in which human and artificial intelligence produce work worth keeping. It moves past prompting into the practices that compound — verification, habitat engineering, specification-first development, and the platform discipline that scales the practice across teams. The habitat is yours to design. Let's build it well.

  14. CISM: The Last Mile
    Your guide to the finish line
    Pete Zerger

    This book covers every topic in the latest CISM exam syllabus, approaching topics from the ISACA perspective. It's 325+ pages organized in a format that makes it easy to drill down on specific exam domains and concepts at-a-glance, making it an essential exam resource for anyone who aims to prepare for the CISM exam without wasting time or money.

  15. Make Bugs (nearly) Impossible
    Resisting human and AI slop in an LLM age.
    Jason Turner

    With the advent of LLMs and AI coding assistants, we are generating code at an ever-accelerating rate. How do we manage this influx of code without getting fatigued and overwhelmed? How do we ensure coding standards are maintained? What practices and tools can we put in place to amplify our efforts while not introducing more bugs?
