Abstract: An operating system service for persistently executing programs comprises a registration service configured to register a manifest defining a persistence mode of a user-controllable program. The operating system service further comprises a runtime service configured, based on the persistence mode defined via the manifest, to detect and reject termination requests for the program, and to detect that the program has terminated and restart execution of the program.

Abstract: An oil lubricated compressor having a universal motor, efficient starting and re-starting characteristics, and a long operating life. The oil lubricated compressor can have a brushed or brushless universal motor which can drive a cooling fan and a pump. The universal motor can achieve a high torque to voltage ratio, as well as a high torque to current ratio, upon starting or re-starting of the compressor. Optionally, the oil lubricated compressor can use a single cooling fan disposed in the compressor at a location which is between the universal motor and a cylinder head of the pump.

Abstract: A computer device is provided that includes a processor and non-volatile memory including stored instructions executable by the processor, the stored instructions being configured to cause the processor to execute an operating system including an application programming interface for an on-demand installer that is callable by installed application programs during run-time. The on-demand installer is configured to receive a request from an application program to install a target resource package of the application program, query an installer server that is a source of an application program package of the application program to retrieve the target resource package from the installer server, and install the target resource package of the application program.

Abstract: A client computing device, including a processor and non-volatile memory. The non-volatile memory may store instructions that cause the processor to receive an application program package. The application program package may include an application program package binary file and an application program package manifest file. The processor may install the application program package in the non-volatile memory at a file system location indicated in the application program package manifest file. The processor may receive a modification package including a modification package binary file and a modification package manifest file. The modification package manifest file may indicate the file system location. The processor may install the modification package in the non-volatile memory. Installing the modification package may include modifying the application program package binary file and/or the application program package manifest file based on the modification package binary file.

Abstract: A computing system is provided that includes a distribution endpoint including one or more processors configured to receive a request from a developer computing device to update a program managed by the distribution endpoint, the program being previously packaged and signed. The one or more processors of the distribution endpoint are further configured to receive a code file including a change to the program, retrieve a package of the program that has not been updated with the change to the program, generate an updated package of the program by adding the code file to the retrieved package of the program such that the updated package of the program logically represents a package of the updated program, and distribute the updated package of the program to an end user computing device.

Abstract: An air compressor assembly can include a support structure with a compressor mechanism, at least one fluid tank, a pair of wheels, and a handle attached thereto. The air compressor assembly can be configured with the compressor mechanism having a perpendicular orientation relative to the at least one fluid tank so as to provide a relatively narrow assembly and to facilitate servicing and/or maintenance of the assembly. Furthermore, the wheels and handle can be configured so that the assembly can be relatively easily located in a balanced transport position. Additionally, an accessory support plate can be attached to the top of the assembly to serve as a dolly.
