Abstract: A computing method receives a shopping list, a GPS location, and products offered at a store. The computing method classifies each shopping list item into one or more hierarchies with an associated confidence level. The computing method determines one or more items corresponding to hierarchies where confidence level that exceeds the predetermined threshold level. The computing method determines a user location and a store within a predefined range of the user location. The computing method determines whether the store includes any of the one or more items and sends a notification to the user including an identification of the store and the item at the store.

Abstract: Providing user software feedback and conflict resolution from a kiosk device. A computer of the kiosk captures audio and visual data from a user during an interaction between the user and software of the kiosk device. The computer analyzes the audio data and visual data to determine at least a sentiment of the user relative to the interaction and determines a score for the interaction. If the score is greater than a threshold, the computer determining at least a portion of the software needs improvement based on the score and the determined sentiment of the user during the interaction.

Abstract: A geographically distributed highly available mailbox system that includes at least first and second data centers servicing different geographical locations. A payload is received by at least one server of the first data center from a first user to be later accessed by a second user. A server from a second data center replicates the payload from the server of the first data center and the first server of the first data center sends notification to the first user that a payload has been uploaded successfully and sends out notification to the second user that the payload has been uploaded. When the second user sends a request to access the payload, the second user is directed to either the first data center or the second data center based on which data center can provide the second user with the quickest access to the payload.
