Social media recommendation engine
Embodiments disclose a recommendation engine that implements a system and method for classifying users and media content, and for determining which media items a particular user will most likely enjoy. By organizing users and media content in a 3 dimensional virtual space and assigning x, y, and z coordinates to each, their relationship and affiliation with/to one another is defined by their distances from each other. When a user rates a media item highly, both that user and that media item move closer together. When a user gives a negative rating to a media item, they move farther apart. Further multiple users who rate the same media item similarly move closer together to form clusters of similar interest groups. This terraforms the virtual space into a natural attraction/separation of like-minded/different-minded users and similar/dissimilar media content. |

Sharing a process in a web client
Configurations for sharing an instance of an executing process for a plug-in based on a session and a cookie data store associated with the session are disclosed. A cookie data store can be associated with a tab running in a corresponding security mode.

If this is the case, the subject technology can then determine whether the previous tab is running in the same security mode (e.g., protected or unprotected) as the new tab. The subject technology then shares the existing plug-in process in the previous tab without instantiating a new plug-in process in the new tab. |

Disaster recovery for split storage cluster
A method, computer program product and/or computer system assigns access to a quorum disk in a split-storage cluster environment when a communication link between storage systems fails. Access to the quorum disk is based on storage system I/O performance. Priority is given to the storage system that has a higher performance before the link failure. When the communication link fails, both storage systems attempt to access the quorum disk. If the system that first attempts to access the quorum disk is the non-priority storage system, a timer is started. If the priority system attempts to access the quorum disk within a predetermined time interval, the priority system locks the quorum disk and forms the cluster. If the priority system does not attempt to access the quorum disk within the predetermined time interval, the non-priority system locks the quorum disk and forms the cluster. |

Application cache replication to secondary application(s)
Replicating a primary application cache that serves a primary application on one network node into a secondary application cache that serves a secondary application on a second network node. Cache portions that are within the primary application cache are identified, and then identifiers (but not the cache portions) are transferred to the second network node. Once these identifiers are received, the cache portions that they identify may then be retrieved into the secondary application caches. This process may be repeatedly performed such that the secondary application cache moves towards the same state as the primary application cache though the state of the primary application cache also changes as the primary application operates by receiving read and write requests. |
