A practical interview reference covering Modern C++ language features, STL usage, concurrency, and performance.

Bad data breaks good code. You’ve written Python that works perfectly in testing, only to watch it fail in production because of a malformed API request, a messy CSV, or a missing config value. That’s the hidden cost of Python’s flexibility: without runtime validation, you’re always one bad input away from a crash. Enter Pydantic. This book takes you from the foundations of data validation to real-world applications in APIs, data pipelines, configurations, and machine learning workflows. Along the way, you’ll explore practical techniques, advanced features, and alternatives like Marshmallow, attrs, and dataclasses, so you’ll always know which tool is right for the job. If you’re a Python developer, data engineer, or FastAPI user, this is your roadmap to writing safer, cleaner, and more reliable code.

Documentation format explains 10 to 127 times more variance in AI-generated code than model choice. We ran 21,462 tests to prove it. This book shows you which formats work, which ones break, and why the industry standard is the worst option for AI consumption.

"Exploitology: Web Apps Exploits" explores web app security, focusing on vulnerabilities, exploitation techniques, and defense strategies. With practical examples and real-world scenarios, this book helps readers sharpen their penetration testing skills and stay ahead in cybersecurity.

This book provides a cookbook of guidelines on designing beautiful (simple to use) and practical (simple to implement) RESTful API.

Much of API security boils down to how you handle identity. In Identity and APIs, we discover the techniques to secure platform access and delegate access throughout a mature API ecosystem.

Most asyncio tutorials introduce async and await on page one and ask you to take the runtime on faith. This book does it the other way around. You build a working event loop in thirty lines of plain Python — no asyncio import — and meet the keywords as labels for parts of a runtime you have already watched run. By the end, async Python stops being intimidating and starts being readable.

The recipes in this book are practical answers to the kind of problems that real Django applications encounter, sometimes on the first day of a project and sometimes deep into the life of a codebase that has grown well beyond its original design. This book is written to guide you to utilize Django 6.0 capabilities in your apps with ease of implementation.
