If a test takes longer than 1 second it doesn't exist

Master the future of AI-powered software development with Claude Code. In this hands-on course, you'll learn how to harness Anthropic's agentic coding system to build software faster, write better code, and automate complex development workflows. Starting with the fundamentals and progressing to advanced techniques like prompt engineering, multi-agent collaboration, automation, and security, each lesson includes practical, working examples you can apply immediately. Whether you're just getting started with AI-assisted development or looking to take your engineering workflow to the next level, this course will give you the skills and confidence to use Claude Code effectively in real-world projects.

Transform AI from a buzzword into a business advantage. This course equips leaders with the frameworks, tools, and confidence to identify high-impact AI opportunities and implement them responsibly.

Build powerful AI agents without relying on the cloud. In this hands-on course, you'll learn how to create intelligent, production-ready agents that run entirely on your own hardware using Ollama. Starting with the fundamentals and progressing to advanced topics like RAG, tool calling, long-term memory, and multi-agent systems, you'll develop real-world applications through practical, copy-and-run examples. Whether you're building personal assistants, automation tools, or sophisticated AI workflows, this course gives you the knowledge and code to build fast, private, and reliable AI agents with confidence.

Stop building fragile AI demos. Learn how to design, test, and operate AI agents like real software systems.

Explore the foundations of American law through a structured introduction to legal systems, constitutional principles, and legal reasoning. Learn how courts interpret laws, how legal arguments are constructed, and how the law influences everyday life.

Learn Python asyncio from zero by building the event loop by hand. Six fetches go from 12 seconds to 3 on one thread, and you understand every line. Most asyncio tutorials throw async and await at you on page one. This course builds the event loop by hand first, in plain Python, so the keywords finally click. Six fetches drop from 12 seconds to 3, on one thread, and you understand every line. No magic. This interactive course has a companion book, Asyncio Without the Magic, on Leanpub at https://leanpub.com/asyncio . The book is the deep, cover-to-cover read; the course is where you make it stick with quizzes, build-it-yourself exercises, and runnable notebooks. They are built to be used together: read the idea in the book, then drill it in the course until it is yours. You get a lot from either one on its own, and the most by far from both together.

Go beyond basic tutorials and learn how to design, deploy, and defend production-grade environments. This comprehensive blueprint bridges the gap between system administration, network architecture, and proactive cybersecurity.Whether you are setting up robust server infrastructures, orchestrating enterprise networks, or integrating cutting-edge defense systems like Wazuh and Fortigate, this course provides the exact, hands-on steps needed to implement secure and highly available digital infrastructures. What you will master inside:• Advanced Systems & Server Administration• Secure Network Design & Routing Orchestration• Active Threat Monitoring & Infrastructure Defense Blueprints

Ever wondered how configuration libraries work under the hood?Most C++ courses teach you how to use libraries. But in this course, you'll build one—from scratch. You'll discover:Why header-only libraries are the gold standard for C++ distributionHow compile-time reflection with CRTP eliminates repetitive mapping codeWhy dot-notation makes nested JSON access elegant and intuitiveHow to provide crystal-clear error messages that save hours of debuggingAnd how to build a production-ready library that you can actually use in your projects No black boxes. No magic. Just C++23 at its best. By the end, you won't just know how to use a configuration library—you'll know exactly how it works, why it's designed that way, and how you can build your own. Ready to build your own typed JSON configuration library in modern C++?

This book takes you straight into the Compose compiler, runtime, and UI layer, all about Compose performance tuning, reading the source line by line and explaining the why behind every design decision, then connecting each internal mechanism back to the code you write every day. With four in-depth chapters, 40+ original diagrams, dozens of "In Practice" sections, and "Pro Tips for Mastery" sidebars, it turns Compose from a set of APIs you memorize into a system you can reason about from first principles, debug with confidence, and optimize with intent.

ChatGPT's memory. AI search. RAG. Recommendation engines. All of it stands on ONE idea — and almost nobody using AI actually understands it. This course takes you from absolute zero (no code, no math, no fees) to building your own AI search engine that finds things by meaning. In the age of AI, this is the line between people who prompt and people who build. Which side are you on?
