Abstract: Data can be serialized in such a manner as to facilitate later delta encoding, even when the serialization is performed using a lossy compression algorithm or an algorithm in which portions of the serialized data are encoded relative to other portions which may be modified. This can be achieved by approaches including preserving keyframe information across modified versions of a file, duplicating information from a previously created compressed file when serializing a later version, or adding change information showing differences between versions of a file during the serialization process.

Abstract: A storage drive and associated system and method for storing data locally at the storage drive and/or at cloud storage may buffer, in a local storage buffer, data to be stored at the cloud and upload the data to the cloud storage from the local storage buffer. Upon receipt of an acknowledgement, from the cloud storage, that the data was successfully uploaded, the storage drive may delete the data from the local storage buffer. The storage drive may provide a ghost file representation of the uploaded data through the storage drive, through which the data uploaded to the cloud storage may be accessed. The storage drive may access multiple cloud storage accounts, each corresponding to a file folder on the storage drive, allowing the user to easily access different cloud storage accounts. The storage drive may recover data that was deleted from either local persistent storage or the cloud storage.

Abstract: A central node/database receives from each mth one of a plurality of M user devices at least one of geographic location information of the mth user device and type information of the mth user device. The node/database registers the M user devices to different groups according to at least one of location criteria based on the received geographic location information and type criteria based on the received type information. Then the node/database sends to each mth one of the plurality of M user devices a set of parameters that define a periodic time window that is specific to the group to which the mth user device is registered. The time window restricts times at which the mth user device can access a data source of spectrum use information. Balancing the number of user devices among the groups, spreads database accesses in time and overloads are less frequent and less severe.

Abstract: Techniques are described herein for automatically selecting the compression techniques to be used on tabular data. A compression analyzer gives users high-level control over the selection process without requiring the user to know details about the specific compression techniques that are available to the compression analyzer. Users are able to specify, for a given set of data, a “balance point” along the spectrum between “maximum performance” and “maximum compression”. The point thus selected is used by the compression analyzer in a variety of ways. For example, in one embodiment, the compression analyzer uses the user-specified balance point to determine which of the available compression techniques qualify as “candidate techniques” for the given set of data. The compression analyzer selects the compression technique to use on a set of data by actually testing the candidate compression techniques against samples from the set of data.
