Obscura is a personal microkernel project designed as a learning ground for low-level operating systems. Its initial aim is to lay the foundations for a minimalist kernel, then gradually evolve towards a modular, stable and simple operating system. ## 🧭 Objectives - Learn and master : - Low-level C language - x86/x86_64 assembler - Modern processor architecture - Fundamental principles of operating systems - Develop a microkernel : - Lightweight and modular - Able to handle hardware interrupts (keyboard, timer) - Support minimal user space - Evolve to a simple OS: - With a rudimentary shell - Isolated user processes - A basis for experimenting with system concepts ## ⚙️ Project status > 🚧 Project under development - Learning phase (year 1) Short-term planned features : - [ ] Multiboot-compatible GRUB bootloader - [ ] Text mode display (VGA) - [ ] Interrupt management (IRQ / keyboard) - [ ] First task manager loop

onix is a minimalist educational operating system written in Rust, created to demonstrate low-level system design in a safe and modern language. It covers kernel essentials such as interrupts, memory management, and multitasking, and includes a tiny Unix-like shell for user interaction. onix is tailored for x86_64 systems and runs in QEMU, making it ideal for learning OS internals while benefiting from Rust’s type safety and concurrency guarantees. It’s a great project for students or...

Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M, STM8. It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.

rc.stupid a Linux daemon that: - repeatedly runs a start script at system startup until this script exits with zero status - regulary runs a check script - runs a stop script at system shutdown Why ? Because startup systems like systemd and upstart are sometimes hard to tune in many situations, like MySQL data directory on a networked filesystem. As rc.stupid does nothing other as running scripts (or anything that may be executed) you may find other use cases like simple clustering.

Super lightweight task scheduler aimed at 8 bit AVR ATmega micro-controllers (perfect for Arduino), although it can easily be used on other hardware like Microchip PIC. It uses simple round-robin scheduling so no priority levels can be set. You choose the time interval by calling dispatchTick(), this is usually in a timer interrupt. Range for number of tasks: 0 to 255 tasks Range for delay: 0 to 65535 ticks Each task only uses 5 byte of RAM. The one task LED blink example only uses 5 bytes of RAM and 476 bytes of program memory for the whole program.

A simple Embedded System Framework that allows rapid development of applications build for AVR family. System is based on a super-loop architecture with check and skip (no-wait) flag event driver system. Supports: UART, SysTick Timer, ADC, SPI, EEPROM, PWM. Also supports: Xilinx FPGA configuration, FPGA SSI interface, smart card reader etc.

The idea behind 'repeat' is to make things easier in the Linux command line environment. Instead of having to script repeats in you're shell of choice - you have a command that repeats things. Use repeat for all you're repeating needs!

Implementation of virtual threads for the XS-1. Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.
