Learn Bash the way it should be taught: by building one real, tested backup tool — not toy examples — one Git commit at a time.

Learn Python the way professional developers actually do. Build real projects, solve practical problems, master debugging, and develop the mindset of a software engineer with this beginner-to-intermediate guide designed for lasting skills—not just syntax.

Turn a static class hierarchy into a real semantic graph: object properties, inverse properties, property characteristics, and domain and range, all hands-on in Protege.

Master Ontology Engineering with Protégé and the EKA Framework—Volume 1 of a multi-volume series that teaches ontology engineering hands-on through the Pizza.owl tutorial and connects it to a modern framework for building executable semantic systems.

Another Production Field Manual: protect APIs before overload becomes an outage with rate limiting, throttling, and tenant fairness.

Mastering Qdrant for RAG Applications is your practical guide to building production-ready RAG systems with the leading open-source vector database. Learn how to design, optimize, and scale high-performance vector search using Qdrant through clear explanations, real-world examples, and hands-on code.

Designing software is only the beginning.The true challenge lies in transforming well-designed systems into reliable, scalable, secure, and maintainable solutions that solve real-world business problems.That is precisely where System Analysis and Design: Concepts, Techniques, and Real-World Applications (Vol-II) begins.

Writing TypeScript is only the beginning.Mastering TypeScript means learning how to design software that is scalable, reusable, maintainable, and capable of supporting applications used by millions of users.That is where The TypeScript Way: A Developer's Guide to Modern Web Development (Vol-II) begins.

Modern web development has evolved dramatically over the past decade.Applications have become larger, more interactive, and increasingly complex. As projects grow, maintaining reliable JavaScript code becomes more challenging, leading to bugs that are often discovered only after deployment.What if many of those errors could be detected before your application even runs?

30년을 엔지니어로 살며 손에 익은 단어들을 하나씩 꺼내, 그 단어가 처음 다가왔던 자리를 적었다. 일터 한구석에 토막토막 남겨 둔 글들이, 어느새 한 권으로 쌓였다.
