摘要： Embodiments of the present invention relate to detecting and rectifying corruption in a distributed clock in a distributed system. Aspects may include receiving a sequence number used as part of the distributed clock at a node and determining if the sequence number is corrupt. In order to provide an effective mechanism for determining a sequence number is corrupt and taking corrective actions, a valid sequence number range may be determined, a propagation count associated with the sequence number may be evaluated, an estimated sequence number may be calculated, and an epoch number associated with the sequence number may be evaluated. Additionally, in exemplary aspects node with a corrupt trusted sequence values may self diagnosis and terminate associated processes to prevent further propagation of the corrupt sequence number.

摘要： A file system which is enabled to use a Metadata Partition instead of VAT for write-once discs, is provided by a pseudo-overwrite method. On applying this invention to a drive apparatus which supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append. When the data is newly written to a logical sector, the drive apparatus writes the data to a physical sector to which the logical sector corresponds. When the logical sector is overwritten the data is written to another unrecorded physical sector in the volume space, and remapping information that specifies the original address, and the remapping address are stored in the remapping table.

摘要： A file system is enabled to use a Metadata Partition instead of VAT for write-once discs, and is provided by a pseudo-overwrite method with a plurality of tracks especially for metadata and file data. On applying this invention to a drive apparatus that supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append (S1701). When the data is newly written to a logical sector, the drive apparatus writes the data to a physical sector to which the logical sector corresponds (S1703). When the data being overwritten is data stored in the logical sector, the data is written to the other unrecorded physical sector in the volume space (S1704), and remapping information is written (S1705). The remapping information specifies the original address of the physical sector, and the remapping address of the physical sector in which the data is written.

摘要： A system and method for sharing information between users based on recognition of the users and their associated processing devices in a scene. Interactions can be physical, verbal or a combination of physical and verbal gestures. Movements of the user and other users are tracked and interactions detected between them. User processing devices are connected by detecting users within view of a capture device, the capture device detecting motion tracking data for the user, such as a skeletal model. Information sharing may be controlled by the processing devices directly, by an intermediary server, or by a combination of the processing device and an intermediary server.

摘要： Systems and methods that create a virtual name space of Universal Naming Convention (UNC) over a local file system (e.g., drive letter based names), via employing a UNC provider and filter arrangement that changes a name in the file object to reparse it to a volume where the local file exists. A name in the file object is changed to a local name (e.g., morphed name); subsequently reparsed and forwarded to a Name Space Owner component (NSO). As such, a request can originate from a UNC stack and reparsed on the local stack. The name space is presented to an application in UNC format, while the underlying file write occur in the file system.

摘要： In response to a request to a file system to perform a requested update, a lock of a first node in a file system can be acquired, and an update of the first node can be performed while the lock of the first node is held. Also in response to the request, a lock of a second node can be acquired, and an update of the second node, which reflects the update of the first node, can be performed while the lock of the second node is held. The update of the first node can be independent of acquiring the lock of the second node. A file system can allow a pair of update operations to be performed in parallel where both operations include updating the same container node. Additionally, while a file system is running, new namespace types can be defined, and the file system can be extended to manage nodes within the new namespace types.
摘要翻译： 响应于对文件系统执行请求的更新的请求，可以获取文件系统中的第一节点的锁定，并且可以在保持第一节点的锁定的同时执行第一节点的更新。 另外响应于该请求，可以获取第二节点的锁定，并且可以在保持第二节点的锁定的同时执行反映第一节点的更新的第二节点的更新。 第一节点的更新可以独立于获取第二节点的锁定。 文件系统可以允许并行执行一对更新操作，其中两个操作包括更新相同的容器节点。 另外，当文件系统正在运行时，可以定义新的命名空间类型，并且可以扩展文件系统以管理新命名空间类型中的节点。

摘要： For each of one or more existing nodes in a file system, pending notifications of updates that have been performed on the node can be identified and sent to one or more other nodes. The file system can be opened for use, and one or more other nodes can be updated in response to the pending notifications while the file system is open for use. For example, this may be done in an operation for recovering from a crash of the file system. Also, a process for dealing with stale data in container nodes in a file system can include processing access requests according to a stale data scheme.
摘要翻译： 对于文件系统中的一个或多个现有节点中的每一个，已经在节点上执行的更新的未决通知可以被识别并发送到一个或多个其他节点。 文件系统可以打开使用，并且可以在文件系统打开使用时响应于挂起的通知来更新一个或多个其他节点。 例如，这可以在用于从文件系统的崩溃中恢复的操作中完成。 而且，处理文件系统中的容器节点中的陈旧数据的过程可以包括根据陈旧的数据方案处理访问请求。
