Regardless of the field! This is a lecture that covers the core fundamentals that developers must know in practice in an easy + code-oriented way. I highly recommend this lecture to all junior developers and job seekers who want to grow.

Welcome to AWS? First Time? Let's learn together, from the basics of modern web systems to cloud deployment. It's not just simple AWS usage or following along with code; you can learn deeply how even difficult CS concepts are applied in the Cloud!

This course is a master class that teaches Kotlin's 🌺 Coroutine, covering everything from theoretical foundations to practical application in a standard manner. It systematically covers core principles and structure, the necessity of asynchronous programming, Coroutine builders and scopes, exception handling, channels, Flow, and other key features frequently used in practice, step by step. Each concept is explained with hands-on examples, making it easy for beginners to understand and immediately apply them. This is the best introductory and practical course for developers who want to build strong Coroutine skills for real-world use.

We will develop a web app that collects data using concurrent/parallel programming in Python, loads it into MongoDB, analyzes it, and visualizes the collected data using FastAPI, a modern web framework. In the process, you will learn and understand Python concurrent/parallel programming using coroutines, multi-threading, and multi-processing, and understand how to use them to improve Python's performance. We will help you apply Python concurrent/parallel codes directly to your work. We will not only teach you how to develop and end, but also how to deploy and operate an actual app on the AWS cloud.

✅ Out of the entire series (1) ~ (7), (4) data structure, algorithm, object-oriented, programming language ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

This course will guide you through the complexities of the Linux operating system, from a strong understanding of the Linux kernel to invoking system calls, process management, and file operations. You will also learn threading and interprocess communication techniques.

Concurrency Programming - Covers the concepts of synchronous and asynchronous programming required in iOS development, as well as everything related to GCD and Operation, which are extensions of those concepts.

I have been working in the IT field for 20 years in development and construction. I would like to be a good guide for those who are entering or starting out in the development field.

This course provides an in-depth study of multithreading and concurrency, from basic principles to practical applications.

Linux is an operating system widely used on various platforms worldwide, including servers, the cloud, and IoT devices. Through this course, you can enhance your competitiveness in the IT field based on a deep understanding of Linux. Furthermore, by acquiring expertise in open-source technology, you can prepare for the future technological landscape and stand out in a high-demand job market.

We explain the core concepts of computer architecture and operating principles that SW developers need to know, using easy-to-understand illustrations.

You can quickly learn about virtual threads supported from spring boot 3.2.0 (+ JDK 21) and get hints on performance improvement in just 1 hour for free.

A course where you can understand core data structure concepts and train to explain them verbally for interviews.

✅ This is an introductory lecture (0) that introduces the entire series of lectures (1) to (7). ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

This course does not teach fashion. It structurally interprets how retail works. Revenue is not merely the result of sales; it is the outcome of a system where KPI design, goal management, inventory turnover, workforce operations, and the gap between headquarters and field strategies are all interconnected. Stagnant sales and organizational conflict are not issues of emotion, but issues of design. Through the interpretation of revenue structures, the principles of KPI operation, the design of operational frameworks, and the analysis of strategic conflicts, this course redefines retail from the perspective of data and structure. It is a process of moving beyond simply understanding retail to gaining a perspective for designing retail.

You need to have a solid understanding of the basic principles of operating systems to understand advanced programming techniques. This lecture is a specialist-level lecture on the dinosaur book, which can be called the bible of operating systems.

This lecture is expected to help students build a foundation in computer architecture.

Through this course, students will learn the overall concepts and flow of databases and operating systems.
