Every crypto channel pins the same frantic warning: the admins will never DM you first. This is the field guide to the scam economy behind that line — impersonated admins, deepfaked founders, pig-butchering, and entire synthetic communities — traced across three eras, from spam to crypto to AI, and the one question that ends it: who is in the room?

Python development has changed dramatically in recent years, and keeping up with the growing ecosystem of tools can be challenging. Modern Python Development in 2026 brings everything together in one practical reference, covering package management with uv, pip, Poetry, and PDM, code quality with Ruff, Black, mypy, and Pyright, testing with pytest and Hypothesis, performance optimization with Cython, Numba, and PyO3, plus build systems, documentation, CI/CD, and security. With clear explanations, real-world examples, benchmarks, and migration guidance, this book helps you choose the right tools and workflows for modern Python projects, whether you are starting from scratch or updating an existing codebase.

Software design is the last craft that never got standardized, so the same problem yields a different structure in every shop and every sprint. Process-First Design is the method for it: design around the process, not the entity, and the dozen small structural decisions you re-litigate every time become engineering, leaving your judgment for the architecture and the domain. One running example carries it from a single use case up to a multi-tenant platform.

A direct route from the basics to real-world Haskell. Master functions, types, and effects, structure real projects, and ship a working blog engine. Along the way, you learn design principles that make you a stronger engineer in any language.

Your first AI integration is usually simple: one provider, one SDK, one model. Then production happens. Costs rise. Rate limits appear. Teams need access control. Security wants API keys centralized. Product wants to test better models. Finance wants to know who is spending what. Suddenly, the real problem is not calling an LLM. The real problem is operating AI as shared infrastructure. The End of AI Vendor Lock-In shows how LiteLLM helps teams build provider-agnostic, resilient, cost-aware AI systems that can route across models, manage fallbacks, track spend, enforce budgets, and reduce dependency on any single provider. If you are building AI products that need to survive real-world production pressure, this book is for you.

The best compliment a reader can pay your code is not "this is impressive" — it is "this was exactly what I expected." Beautiful but Boring teaches the discipline of writing Python that earns that compliment: precise naming contracts, type annotations that say what a function actually requires, and a framework for maintaining those standards consistently across a codebase, a team, and a career.
