MoCo is a system that monitors and controls SCADA points, such as temperature, HVAC, power, lighting, sprinkler systems, and more. It has industrial capabilities, but is scalable from very small home systems to enterprise, world-wide ones. It works with inexpensive I/O bridges (including X10, Insteon, and 1-wire) from a number of manufacturers. It has sophisticated history logging and diverse control capabilities, as well as a 117-page implementation manual.
YASP is a simple and open protocol for building networks with small microcontrollers. It is designed to have a small footprint for easy implementation with minimal hardware resources, but without sacrifice advanced features and future growth. The protocol scalability is implemented using variable length fields. The physical layer use the NRZ encoding as in RS-232, but using dominant and recessive bus states to provide a reliable way to detect collisions.
The Discrete Event Calculus Reasoner allows a programmer to add common-sense reasoning capabilities to programs. It supports deduction/temporal projection, abduction/planning, postdiction, and model finding. It allows default reasoning about action, change, space, and mental states. It is based on the event calculus, a comprehensive and highly usable logic-based formalism. It helps applications understand the world, make inferences, adapt to unexpected situations, and be more flexible.
phpMyRecipes is a simple Web-based application for storing and retrieving recipes. It implements security to allow recipes to be searched and viewed by anyone, but all functions involving changes require additional privileges to be granted by the administrator. Recipes are categorized, and new categories are easy to create. Ingredients are added to the database on-the-fly as they are used in recipes. Unit types (such as "cup" or "teaspoon") are also stored in the database, and unit "plurals" are also handled correctly. A robust search feature that supports a wide range of criteria, including words found (or not found) in the instructions, the recipe name, category, and ingredients list is included.
Hocuspocus is a small and extensible Web server for controlling key Linux applications via a Web server. This means you can adjust things like system volume from any browser, including a WiFi enabled PDA such as the iPhone. Multiple such servers can be controlled via a single service manager, enabling whole home remote control.
