No prior experience required.
Your C# skills are worth more today than they were a year ago — if you know how to put a language model in the loop. This book shows you how, with the Microsoft Agent Framework: real tools, RAG, multi-agent orchestration, plus the hosting, observability, and safety that separate a demo from a system you ship. Nineteen chapters. 120 runnable projects. No Python detours. Just C# and .NET 10.
Skip the black-box frameworks. Build a production-grade AI coding agent from scratch in pure Python - cloud or local, tested with pytest, all in a single file.
Take a look under the hood of your Windows personal computer. Locate and eliminate security problems. This book shows you how to become an amateur digital Sherlock Holmes.
Build a working SQL database engine in C++20 -- from raw pages to a realquery executor -- one compilable, measured challenge at a time. Everyperformance claim is a benchmark you run yourself; every unit ends with areal bug, caught red-handed and fixed. Nothing asserted. Everythingdemonstrated.
Most architecture books teach you how to design systems. This one teaches you how to become the person who designs them. This book covers everything the job actually requires: the mindset, the technical depth, the decisions, and the organizational and human dimensions that no purely technical book addresses.
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.
A best-selling book. The practitioner's guide to Claude Code in production. Thirty-one chapters covering the agent loop, tools, hooks, MCP, the Claude Agent SDK, permissions, multi-agent orchestration, evals, observability, and cost engineering. Includes a full walkthrough of Anthropic's financial services reference agents. Code from real production systems, not toy examples.
One hundred Kaizens. Four phases. One discipline. Kaizen of the Day is a companion to Ishi: The Discipline of Determined Intent, built to turn the Ishi Spiral into daily practice. Each entry is small, bounded and practical. Decide. Forge. Persist. Reflect. Read in sequence or open to the phase that matches the problem in front of you. This is not a book of motivation. It is a book of governed action.
Modern networks like the Internet — explained as simply as possible — but no simpler.
This book teaches harness engineering as a discipline. Not magic prompts. Not vendor tricks. Engineering practice applied to a new substrate.
Claude can write a chapter, a module, or a report section in minutes — that's exactly what makes long projects dangerous. Beyond Chat is a practical system for staying in control of long, complex work: how to define a project so it holds together, keep a memory that survives sessions, and know when things have quietly drifted off course.

As an academic, I like Leanpub because it lets me write and get my ideas out there quickly. Leanpub is simply the best place for publishing my books.
Leanpub's book-creation tools allowed me to focus on creating the types of books I wanted to write instead of worrying how to create my own book publishing toolchain. I have never regretted using Leanpub to publish my ebooks.
Leanpub takes the pain out of publishing. They provide the tools, you provide the books and then magic happens.
I love using Leanpub because I can write my book using simple Markdown notation. Leanpub let's me focus on my content and they handle the rest.
Leanpub is a game changer for independent authors, removing the hassles associated with formatting, book production, and electronic sales, freeing up the time to do what we do best: write.
Leanpub helped me achieve my goal of publishing a book. Its simple, easy to use interface got my book up and making money within weeks, I love Leanpub!
Leanpub helped me gauge interest in my book, get payments early on when it was only a few chapters, and has got me a bunch of sales just from people browsing around the site.
Leanpub helps me see my books as I write them. Even better, I can find readers early, to read my books and offer suggestions. I can pivot, if I see the need.
Leanpub made it simple for me to run with my book idea and build my reputation in the Ruby community. I went from first draft to first sale in days, not months or years.
Four years ago, I joined Leanpub to just give it a try. Today, over 28,000 book sales later, I cannot help but say that I'm the biggest Leanpub fan on this planet!
Leanpub makes publishing your own book super easy. The fact that you can release updates continually helps with the mindset of getting a minimum version out ASAP and then iterating to improve.
I earn more royalties from my books on Leanpub than I do with well established publishers or through Amazon (which I publish on thanks to Leanpub's mobi conversion).
Leanpub allows me focus on content, takes care everything else and offers an amazing author royalty. It’s a fantastic platform for writing and publishing books.
I love that Leanpub makes writing and publishing a beautiful book so simple. I no longer spin my wheels with layouts and formats - Leanpub gets out of the way when it's time to write, and then automates everything when it's time to publish.
With Leanpub, the first person who purchased my book for $9.99 almost two years ago (and only received a preface, and two short intro chapters) has had access to almost every bit of knowledge I've gained in those two years, and *that's* the value.
Simple and lean, forces me to focus on writing and marketing, and pays excellent royalties.
Leanpub forces you to focus on writing and gives you immediate feedback. Allowing Leanpub to take care of the curation and delivery helped me focus on shipping my book.
While most eBook exporter apps today can generate PDF files and many support ePub, there's one tool we recommend above all after trying 8 of the most popular: Leanpub.
