In some embodiments, a computing system determines, based on stored user information retrieved from a mobile user device and associated with a particular user, a location-specific affinity of the particular user for a product at a particular geographical location. The location-specific affinity indicates an interest of the particular user in the product that increases when the particular user is positioned at the particular geographical location. The computing system designs a geo-fence targeted to the particular user based on the location-specific affinity, where messages are transmitted to the mobile user device if the particular user is within a boundary of the geo-fence. The geo-fence defines a geographical area that includes the particular geographical location and that is associated with a provider of the product. The computing system causes a telecommunication server to transmit the message to the user device when the user device is positioned within the designed geo-fence.

A method for recognizing hand gestures when the hand is held in front of the user's upper body. The method detects dominant features associated with the upper body, including features on the face (eyes and mouth etc.) and the shoulder extremes. Geometrical relations among these features are used to judge whether the face/head has turned to the side relative to the shoulder. If not, a face-shoulder coordinate system is established using these face-shoulder features, and the hand images are transformed into this new coordinate system. This in effect defines hand gestures relative to the user's face and shoulder, thus significantly reducing the dimensions of the feature space for hand gestures. This face-shoulder coordinate transform can be combined either with traditional appearance-based hand gesture recognition methods, or with a conventional or hybrid deep neural network for RGB or RGB-D images.

Change records received from a primary database are applied for a standby database, creating dirty buffer queues. As the change records are applied, a mapping is maintained, which maps timestamps to logical times of change records that were most recently applied at the timestamp for the standby database. On a periodic dirty buffer queue processing interval, the mapping is used to determine a target logical time that is mapped to a target timestamp that is prior to a present timestamp by at least a checkpoint delay. The dirty buffer queues are then processed up to the target logical time, creating an incremental checkpoint. On a periodic header update interval, file headers reflecting a consistent logical time for the checkpoint are also updated. The intervals and the checkpoint delay are adjustable by user or application.

Described is a system for reclaiming unused storage space when distributing backup data to storage performance-based tiers within a clustered storage environment. The clustered storage environment may organize nodes into storage performance tiers, and each node within a tier may be tuned for a particular type of workload. Accordingly, the system implements a file system that provides the ability to reclaim unused storage space (e.g. perform garbage collection) for specific nodes or tiers independently despite implementing a global namespace. The global namespace may group (or co-locate) aspects of file information with the backup files. For example, file information may be stored on the same node that stores the associated backup files. Accordingly, the system may reclaim unused storage space for each node, or set of nodes forming a storage performance tier, independently and efficiently.
