Nuttx is a real-time embedded operating system (RTOS). It has a small footprint that is usable in micro-controller environments. It is fully scalable from tiny (8-bit) to moderate embedded (32-bit) systems. It also aims to be fully compliant to standards, to be fully real time, and to be totally open.
PSX is a PHP framework for creating RESTful APIs. It helps you to build clean URLs serving Web standard formats like JSON, XML, Atom, and RSS. It includes a handler system that abstracts away SQL queries from domain logic, a routing system that executes correct controller method for the location of the controller and the method annotation, and a flexible data system that converts database records into formats like JSON, XML, Atom, and RSS. A lightweight DI container handles dependencies. The controller supports request and response filters that can modify the HTTP request or response, and filters are provided for Basic and Oauth authentication.
The Whole Platform is a technology for engineering the production of software. It provides an Eclipse-based Language Workbench for developing new languages, manipulating them using domain notations, and transforming them using a generative model driven approach. The languages bundled with the Whole Platform include: modeling languages; query and transformation languages; integration languages for grammars, XSD, RDB, and Java libraries; and popular languages such as Java and XML.
