Abstract: A file system with distributed resource caching that includes cache volumes and agents that may be associated with clients of the file system may be provided. A cache allocation for each agent may be determined based on a capacity of the cache volumes and a number of the agents such that each cache allocation is associated with tokens that each represents a reserved portion of free space in the cache volumes. Storage jobs may be provided to the agents. Data associated with the storage jobs may be stored in the cache volumes. The cache allocation for each agent may be reduced based on the data stored for each agent.

Abstract: Embodiments are directed to a file system engine that provides a file system that includes a plurality of blocks on a file storage tier with portion of the blocks associated with a cache storage tier. A cache engine provides heat extents that include a heat score and a run length value such that the heat extents are represent activities associated with the blocks. Heat extents associated with file system activities are determined based on a position of the blocks that corresponds with the run length values of the heat extents and sectors on the file storage tier. Heat scores associated with the heat extents may be modified based on the activities and distribution models to conform the heat extents with the distribution models. Blocks associated with heat scores that are less than a threshold value provided by the distribution models may be disassociated from the cache storage tier.

Abstract: A facility for managing filesystem object storage quotas (i.e., size limits) in a storage environment is disclosed. The facility enables users to establish, modify, and remove quotas on directories and files within a filesystem. Each quota acts as a soft limit on the size of the associated filesystem object, including any child objects of the filesystem object. The facility improves the speed at which the system can test for and identify violations of quotas established for individual filesystem objects by using aggregation and reconciliation techniques rather than constantly traversing a filesystem in its entirety to test for violations of quotas.

Abstract: Embodiments are directed to managing data in a file system over a network. A file system that includes a master node and client nodes may be provided. A master quorum value and a client quorum value having the same value may be provided. A profile catalog associated with the master node that includes parameters may be provided. Profile registers associated with the client nodes may be provided. Change actions may be executed on each client node based on change information provided by the master node. In response to errors, access to the file system may be suspended; the master quorum value may be modified to indicate that the file system is out of quorum; recovery actions may be executed; the client quorum value at each client node may be modified to correspond with the master quorum value; and access to the file system may be restored.

Abstract: A method described herein includes receiving data that identifies a web page, wherein the data that identifies the web page is desirably displayed to a first individual and resolving the web page to generate a markup language document, wherein the markup language document comprises unstructured data. The method also includes extracting portions of the markup language document and generating a structured data object, wherein the structured data object includes the portions of the markup language document. The method further includes causing a summary of the web page to be displayed to the first individual, wherein the summary of the web page is based at least in part upon the structured data object.

Abstract: Within a social network, a user may establish a set of contacts who share with the user various content items and comments related thereto. However, these content items are often hosted by a content source outside of the social network, and the user may have to transition to the content source to view the content item, and then transition back to the social network to submit a comment. Instead, a device may monitor the social network to record shared content items. When the user requests a presentation of the content source, notifications of the content items hosted by the content source that have been shared with the user, including an identifier of the contact sharing the content item with the user (e.g., a depiction or avatar representation of the contact and a link to a social profile of the contact) may be included in the presentation.
