Abstract: A potty-training system includes a base, a mounting assembly for mounting the base onto a toilet, an arm extending from the base, a target mounted on the arm, a sensor, and multiple light emitters operatively connected to the sensor to cause the emitters to activate in chronologically ordered succession when the target is struck for a duration of time. The light emitters may be spaced along the arm between the target and the base. The multiple light emitters may be activated in chronologically ordered succession by which at least one of the multiple light emitters closest to the target is activated first. A control input device adjusts a rate at which the multiple light emitters are activated in chronologically ordered succession when the target is struck. A sound emitter may also activate when the target is struck.

Abstract: A system and method for building virtual appliances using a repository metadata server and a dependency resolution service is provided. In particular, a hosted web service may provide a collaborative environment for managing origin repositories and software dependencies, whereby remote clients may follow a simple and repeatable process for creating virtual appliances. For example, the repository metadata server may cache and parse metadata associated with an origin repository, download software from the origin repository, and generate resolution data that can be used by the dependency resolution service. The dependency resolution service may then use the resolution data to resolve dependencies for a package selected for an appliance, wherein the dependencies may include packages that are required, recommended, suggested, banned, or otherwise a dependency for the selected package.
