Patent number: 9934301Abstract: Methods and systems for efficient file replication are provided. In some embodiments, one or more coarse signatures for blocks in a base file are compared with those coarse signatures for blocks of a revised file, until a match is found. A fine signature is then generated for the matching block, of the revised file and compared to a fine signature of the base file. Thus, fine signatures are not computed unless a coarse signature match has been found, thereby minimizing unneeded time-consuming fine signature calculations. Methods are also provided for determining whether to initiate a delta file generation algorithm, or whether to utilize a more efficient replication method, based upon system and/or file parameters. In accordance with additional embodiments, the lengths of valid data on physical blocks are obtained from physical block mappings for the files, and these lengths and mappings are utilized for delta file generation, to minimize unnecessary signature computations.Type: GrantFiled: October 2, 2012Date of Patent: April 3, 2018Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Piyush Kumar Srivastava, Madhusudhana Honnuduke Srinivasa Murthy

Publication number: 20130311556Abstract: Methods, system and computer readable medium for generating a dynamic group includes defining a theme for the group. A group is initiated for the defined theme and plurality of users are invited to join the group. The activities of the plurality of users that have joined the group are monitored over time, wherein the activities are directed toward enriching information associated with the defined theme or one or more sub-themes of the defined theme. User dynamics of the group are adjusted dynamically based on the monitored activities of the users. The adjusted user dynamics define a strength value of the theme for the group of users.Type: ApplicationFiled: May 18, 2012Publication date: November 21, 2013Applicant: Yahoo!

Publication number: 20130311258Abstract: Techniques are provided for offering a deal to a group of users, and for determining differential discounts for the users of the group that participate in the deal. A deal is offered to users of a group of users formed in association with a corresponding topic. Each user of the group is enabled to selectively accept the deal. The deal is confirmed with a plurality of users of the group that accepted the deal. Discounts for the deal are differentially assigned to the plurality of users based on at least one parameter such that at least two users that accepted the deal have discounts that are different from each other.Type: ApplicationFiled: May 16, 2012Publication date: November 21, 2013Applicant: YAHOO!

Publication number: 20130103496Abstract: A computer-implemented method for generating user profiles based on future locations of a user includes receiving one or more future locations along with time duration of a user at each of the one or more future locations. The computer-implemented method also includes identifying a plurality of attributes associated with the one or more future locations. Further, the computer-implemented method includes inferring future interests of the user. Moreover, the computer-implemented method includes dynamically generating user profiles in accordance with the time duration of the user at each of the one or more future locations.Type: ApplicationFiled: October 19, 2011Publication date: April 25, 2013Applicant: Yahoo!
