Linux as a work environment (Desktop and servers)
From 75.25 $ /h
Introduction to Linux as a work environment course.
This course is designed for people who want to use Linux productively in their daily work, whether as an alternative to Windows or macOS, or as their first introduction to free and open-source operating systems. We start from scratch and explain in an easy-to-understand way how a Linux system works, how the desktop, file system, and user management are organized, and how to install and use common software for everyday tasks. The goal is not just to learn how to "use" Linux, but to understand it well enough to work independently, securely, and efficiently.

Extra information
For online classes, you need a computer with Linux installed. If it's in-person, we can install the system together.

About Me
I trained in philosophy and history, but I've been working in computer science for over thirty years. This combination shapes my understanding of technology: not as a set of tools, but as a system that influences how we think, decide, and work. Technology is never neutral, and that's why it demands a critical and responsible perspective.
I founded Mercerik IT-Consulting SLU to support small and medium-sized businesses that need clarity, stability, and control over their IT. I carefully analyze each environment, design precise solutions, and create systems that work reliably and easily. I don't impose trends or create dependencies; I strive to ensure that technology once again serves people.
Artificial intelligence is part of my work because I know it's transforming our world. I don't treat it as something new, but as a historical process that demands understanding and critical thinking. My role is to help navigate this change with serenity and purpose.
I work in three languages (Spanish, English, and German) and live in Barcelona. I believe in honest conversations and straightforward solutions. If you're looking for a thoughtful and responsible approach to your IT, I'd be happy to hear from you.

This course is designed for individuals who want to learn how to use ChatGPT effectively and consciously, both personally and professionally. It explains the system's basic operation, the different available models and their differences, as well as the tool's capabilities and limitations. We cover environment configuration, the correct use of prompts, adapting language to the objective, and creating custom GPTs. We also introduce image generation and the responsible use of AI in daily work. The approach is practical and critical: it's not about "automating everything," but about learning to use AI as a genuine support for thought and work processes.
