Abstract: A computer stores, within a single user account, multiple supervised computing resources and multiple additional computing resources. The multiple supervised computing resources are associated with a security policy. The computer executes a first instance of a specified application that lacks read access and lacks write access to any and all of the multiple supervised computing resources. The computer executes, simultaneously with the first instance, a second instance of the specified application that accesses at least a portion of the multiple supervised computing resources. The computer applies rules from the security policy to the second instance of the specified application while foregoing applying the rules from the security policy to the first instance of the specified application.

Abstract: A computer causes display, at a graphical user interface of a computing machine, of a visual indicator indicating that tracking is ongoing. The visual indicator comprises a border separating at least one first region of the graphical user interface and at least one second region of the graphical user interface. The computer facilitates tracking, by a supervision service, of activity of the computing machine with respect to at least one software application that generates graphical output within the at least one first region. The computer forgoes facilitating tracking, by the supervision service, of activity of the computing machine with respect to at least one software application that generates graphical output within the at least one second region.

Abstract: A computing machine stores supervised computing resources and private computing resources. The computing machine facilitates tracking, by a supervision service, of activity of the computing machine with respect to a supervised computing resource of the supervised resources that is executing on the computing machine. The computing machine supports user privacy, by the supervision service, with respect to a private computing resource of the private computing resources that is executing on the computing machine.

Abstract: A solar tracking apparatus is provided having pivoting struts located proximate the north and south sides of the collector surface. The crossed struts permit the inclination angle of the collector surface to be varied throughout the day without heavy supports. The support frame can be adapted for quick assembly, disassembly and transportation.

Abstract: A hybrid solar collector is disclosed having a passive solar collector unit and active photovoltaic panels. The inclination angle of the photovoltaic panels is optimized by linking the panels to the passive unit and its associated tracking controls.

Abstract: A passive solar collector utilizes a support constructed of precisely machined foam to simplify the construction and calibration of the reflective surface. Further improvements include sensor-based positioning, and a receiver having inflow and outflow conduits adapted to improve thermal efficiency.
