Abstract: Each of a plurality of virtual machines (VMs) is stored in a halted form in a library for retrieval from the library and re-starting on a host. Each re-started VM includes a plurality of software constructs, each of which is at least potentially non-current and requires a software update. To update a non-current VM, such VM is retrieved and re-started on a maintenance host, and each non-current software construct is allowed to be updated by obtaining the required software update from a corresponding update source as a patch. Alternatively, the VM is mounted to a computing device, constituent components of the mounted VM are examined to determine whether each software construct thereof is current, and each non-current software construct is updated by obtaining the required software update from the corresponding update source as a patch and applying same to the mounted VM.

Abstract: A facility for receiving an embedded policy is provided. The facility checks an application program image for the presence of an embedded policy. If an embedded policy is detected, the facility extracts the policy from within the application program image. The facility may then apply the extracted policy to the application program image before the application program image is loaded and/or executed. Moreover, the facility may check the application program image's integrity prior to extracting the embedded policy.

Abstract: A facility for automatically processing software patches is described. The facility receives in a computing system a distinguished patch package for modifying the behavior of a programmatic entity. The facility automatically extracts from the distinguished patch package (1) patch application information that identifies a distinguished programmatic entity against which the patches to be applied, and (2) patch behavior information that specifies a manner in which to modify the behavior of the distinguished programmatic entity. The facility automatically adds to a patch table a distinguished entry containing the extracted patch application information and patch behavior information.

Abstract: A facility for providing access authorization is provided. The facility initially enforces a first, less restrictive policy when making its access control decisions. Subsequent to detecting an anomaly, the facility enforces a second, more restrictive policy when making its access control decisions. The facility returns to enforcing the first, less restrictive policy when the anomaly no longer exists. In another embodiment, the facility enforces a policy after detecting an anomaly and until the anomaly has ended.

Abstract: A facility for augmenting software in a target computer system is described. The facility receives and augmentation specification in the target computer system. The augmentations specification specifies: (a) a function to be augmented, (b) a parameter of the function to be tested, (c) a test to apply to the specified parameter, and (d) and modification to perform to the behavior of the function if the specified test is not satisfied by the specified parameter. When the specified function is invoked on the target computer system, if the specified tested is not satisfied by the specified parameter, the facility performs the specified modification to the behavior of the specified function.

Abstract: A method and a system for determining a depth of a space, the system includes: a scanner for scanning, by a single broadband light beam, the structural element and the area of the surface of the object, wherein the area at least partially surrounds the structural element; a sensor for detecting interference patterns generated when the single broadband light beam concurrently illuminates a portion of the area and at least a portion of the structural element; and an analyzer for analyzing the interference patterns to determine the height difference between the area and the structural element.

Abstract: A facility for setting and revoking policies is provided. The facility receives a request from a controlling process a request to set a policy on a controlled process, and determines whether the controlling process has privilege to set the policy on the controlled process. If the facility determines that the controlling process has privilege to set the policy on the controlled process, the facility sets the policy on the controlled process, which causes the policy to be applied to the controlled process to determine whether the controlled process has authorization to access one or more resources.

Abstract: A scanning system for use in inspecting or writing on a substrate minimizes vibrations by applying movement-actuating forces directly between a carriage and a countermass which are both free to move along parallel tracks. Forces for decelerating and accelerating the scanning carriage are preferably applied along a minor part of a length of movement of the carriage. The carriage is then isolated from forces applied parallel to the track while moving along a major part of its length of movement. As a result, the carriage travels smoothly with approximately uniform speed during it's operative pass, without suffering from vibrations introduced by direct closed-loop feedback control.
