This project is an educational operating system kernel designed to demonstrate the fundamental architectural principles of memory paging and process management. It is implemented as a minimal kernel that serves as a practical reference for building a functioning system from the ground up. The implementation features a preemptive multitasking kernel that switches execution contexts between threads to share a single CPU. It includes an x86 virtual memory manager that uses paging to map virtual addresses to physical memory and isolate processes. The system covers low-level hardware interfacing

This project is a comprehensive educational framework and curriculum designed to transition beginners into proficient security engineers. It provides a self-taught hacking curriculum centered on mastering system internals, programming, and attack techniques through structured pedagogical paths and recursive learning. The framework distinguishes itself by integrating a productivity system specifically for engineers, which combines block-based time scheduling and incremental task management to prevent burnout and overcome procrastination. It further connects technical growth to professional adv

Kernel is an educational hobby operating system and low-level systems programming project written in Rust. Designed for students and hobbyists, the project provides a minimalist environment to explore computer architecture, CPU design, and kernel development directly on hardware without relying on a standard library or underlying operating system. The implementation features a freestanding language runtime and a custom target specification that replaces standard library components for bare-metal execution. It includes a multiboot bootloader interface to parse early-boot hardware handoff stat
