“An e-book word-of-mouth bestseller, finally officially published as a print book!”
The definitive guide to essential IT fundamentals for the AI era, completed by Alex of “Tech Note Alex,” a YouTuber with 110,000 subscribers.
“In an age where AI writes the code, why do we still need to understand IT fundamentals?”
With the emergence of generative AI tools such as ChatGPT and Cursor, the era of “Vibe Coding”—creating programs through conversation alone—has begun. Now, anyone can bring their ideas to life without having to memorize every coding syntax individually.
However, when errors occur in AI-generated code, when the database won’t connect, or when the software needs to be deployed to a server, development comes to a standstill if you don’t understand the underlying principles. In the age of AI, the skill you truly need is not the ability to type every line of code yourself, but the technical foundation to understand the big picture of how software is built and executed.
《Technical Notes》 by Alec, a 25-year IT expert who has earned immense love from readers by explaining difficult IT concepts in the simplest way through the YouTube channel “Technical Notes with Alec,” has been published as a print book thanks to the enthusiastic support of readers.

Hello~ This is Alex from Tech Note.
There are many people thinking about the cloud field, right?
It is a promising field that is continuously being used more and more by companies.
For those of you who are unsure about how to prepare
I have prepared a lecture that includes almost everything I know.
There is a lot of content related to development, protocols, architecture, servers, and networking related development and system construction.
Because, after all, the cloud is also a server environment for development.
I don't think it'll work if you only study cloud without knowing development.
I even included a video at the end so you can practice.
I think this will be helpful to developers and those thinking about the cloud field.
