What if, instead of customizing an existing operating system, I tried to build my own?

That's the idea behind SEA OS, my personal operating system development project.

I'm building SEA OS as a custom operating system, with the long-term goal of creating its own kernel, drivers, and user interface.

Why I'm Building SEA OS

I don't just want to use computers. I want to understand how they work underneath the applications we use every day.

How does a computer boot?

How does a kernel communicate with hardware?

How does keyboard input reach an application?

And how do you turn low-level code into a complete operating system?

SEA OS is my way of exploring these questions by building things myself.

The Technology

My current development work involves:

C and C++ for low-level system programming

Assembly for architecture-specific code

GRUB for booting the system

QEMU for testing in a virtual machine

Make for building the project

I'm working on the kernel bootstrap and experimenting with hardware input…
