Abstract: A messaging system in one embodiment includes a messaging app and a polling extension app. The polling extension app is configured to create data for a polling context that is displayed in a view hosted by the messaging app to allow voting by users selected for the poll and to update the polling context with the votes from the users. The messaging app launches the polling extension app, and the polling context is communicated between the polling extension app and the messaging app through an interprocess communication.

Abstract: A data storage device includes storage media with multiple media zone attributes of storage performance. The storage device includes a data channel that is connectable to a host system. The data channel receives an object from the host system that has a requested storage attribute attached to the object. The storage device comprises an object-based storage interface that couples between the data channel and the storage media. The object-based storage interface schedules the object for storage in a selected zone of the multiple media zones based on the attributes and requested attributes.

Abstract: The disclosure is related to systems and methods for checking the integrity of a data transfer to or from a buffer or other data storage medium. Check values can be added to a data object in a data object based file system. From the check values, a device receiving the data object may determine an integrity or validity of the received data object based on the check values. In a particular embodiment, a hash value may be determined based on the check values. The hash value may be stored in the metadata of the transferred data object. The receiving device may re-calculate the hash value from the check values and compare it to the stored hash value to determine an integrity of the received data object.

Abstract: A data storage device comprises storage media including physical data blocks. The data storage device comprises a storage circuit. The storage circuit compresses a user data block into a compressed user data block before storing the compressed user data in one of the physical data blocks, leaving an unused block portion of the physical data block. The data storage device comprises a remapping circuit that remaps the unused block portion to an opportunistic block address. The data storage device comprises a circuit that stores data in the unused block portion.

Abstract: A storage device comprising has a storage medium, a read-write mechanism, an object-based file system interface, and a controller. The read-write mechanism is adapted to read and to write data from and to the storage medium. The object-based file system interface within the storage device is adapted to organize and access data on the storage medium as objects and to access attributes of each data object. The controller is adapted to generate redundancy data for each data object to be stored on the storage medium according to the associated attributes and to store the data object and its associated redundancy data on the storage medium.

Abstract: A method comprises: storing data for a plurality of objects in a plurality of physical blocks on a storage medium, using information about the objects to identify logical addresses for the physical blocks used to store the data, pre-fetching the data from particular ones of the physical blocks based on the identified logical addresses, and storing the pre-fetched data in a memory. Apparatus that performs the method is also included.

Abstract: A method for processing requests for information from a disc drive comprising: (a) receiving a plurality of requests, wherein each of the requests has application level information associated with it; (b) identifying a first group of the requests that fit within a time interval; (c) using a scheduling algorithm with disc information to schedule one of the requests in the first group; (d) adjusting the length of the time interval; (e) identifying another group of the requests that fit within the adjusted time interval; (f) using the scheduling algorithm to schedule one of the requests in the other group; and (g) repeating steps (d), (e) and (f). An apparatus that processes requests for information in accordance with the method is also provided.
