Low power application-configurable Operating System
langOS is an open-source Operating System for Tiny Scale Devices. It supports platforms based on the MSP430 and AVR microcontrollers and is fully written in C.
langOS aims to be simple, easy to configure and independent of the development host platform. It should be comfortable on Windows, Linux and MacOS platforms.
ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Tiny Alien is presented as a micro web server platform that can deliver dynamic websites securely.
Backed by a ultra-light server sided scripting ability Tiny Alien packs a very powerful punch into the smallest of spaces.
This rendition allows you to host a tor based web service that is highly resilient and easily deployed thanks to http://www.floodgap.com/httpi/ for their excellent webserver. ;)
This is not for the faint of heart as you will be required to understand shell commands throughout to get the best from this Tiny Alien platform.

Nemesis is a tiny real time operating system kernel based on x86 PCs.
Its main purpose is to serve as a simple but realistic example of an real time OS kernel running on real hardware..the purpose of this is that it can be embedded in small devices lik
