Abstract: Implementations are provided herein for non-disruptive upgrade including rollback capabilities for a distributed file system within a cluster of nodes. To continue availability of the file system to external clients during the upgrade process, nodes can be upgraded piecemeal, for example, in one implementation, one node at a time. When a node is undergoing certain stages of the upgrade process, external clients can be directed toward the remaining nodes of the file system that are not currently being upgraded, including already upgraded nodes, to perform client activity. During the upgrade process, a first subset of nodes can be running in an upgraded state while a second subset of nodes can be in a non-upgraded state, both providing access to external clients in a seamless manner. During the upgrade process, an administrator can decide to rollback any upgrades and return the distributed file system to its previous version (e.g.

During the upgrade process, a first subset of nodes can be running in an upgraded state while a second subset of nodes can be in a non-upgraded state, both providing access to external clients in a seamless manner. In one implementation, a second namespace can be established at the onset of the upgrade process that reflects the new version of the operating system.

Abstract: Enhanced computer- and network-based methods, techniques, and systems for an enhanced file server that provides search and recommendations “in-band” as part of a request to the file server are provided. Example embodiments provide a Enhanced File Server (“EFS”), which enables file servers and the like, to search for and/or to recommend information (e.g., content, data, or the like) based upon a file request to the file server. This enables a user of the EFS to avoid the use of a separate search or recommendation system, such as a search engine, to find information. An Enhanced File Server implements its own search and recommendation capabilities and allows users to search for and obtain recommendations for information through its standard file-access mechanisms. Searches and requests for recommendations are performed using especially constructed file names The EFS may present results to the user using synthesized content.

Abstract: Methods, systems, and techniques for recommending content using a measure of security group based similarity are provided. Embodiments described herein provide enhanced computer- and network-based methods, techniques, and systems for a recommender system, e.g., for content servers, that uses security group membership as the basis for determining user similarity. In particular, upon request for a recommendation, an enhanced content provider, through the use of the Security Based Recommender (SBR), provides indications of similar content based upon the security group membership of the requestor. The SBR determines similar content by determining what content was accessed by others within the security group membership of the requester. The recommendations may be ranked or filtered or combined with other types of recommendations, such as social network filtering, statistical based filtering, or the like.

Abstract: The customized viewing of an event, such as a sports event, includes identifying an object in the sports event with an identification device, capturing visual media such as photograph(s) or video of said sports event and marking the visual media upon the recognition of the object by a camera. The captured visual media is encoded into a variety of display formats for easy viewing on any selected display device. Electronic information tags include real-time and/or historical information specific for the object and is stored on a database and linked with a unique identification used to identify the object. A user selects items such as object(s) and tag(s) from selection matrixes for the captured visual media and produces a filtered visual media that is customized to the viewing desires of that user.
