Abstract: A method for setting permissions for a group of users of a computer system. The method includes receiving data that defines a role for a first group of users, the role including one or more permissions each defining a permitted activity of the first group of users with respect to data of users in a second group of users, and setting the one or more permissions based on the defined role.

Abstract: Disclosed are database-related systems, apparatus, methods and computer program products for processing personal preferences submitted by users regarding feed items of a social network feed of a social networking system. In some implementations, personal preference data received from computing devices associated with users of the social networking system is monitored. The personal preference data indicates personal preferences submitted by the users to apply to selected feed items of the social network feed. The personal preference data indicates that each user feels positive or negative about information indicated by a selected feed item. A characteristic of the personal preference data is assessed. At least one computing action is determined to perform based on the assessed characteristic and on the personal preference data.

Abstract: Disclosed are systems, apparatus, methods and computer-readable media for processing a preference indication for a feed item of an information feed. In some implementations, a preference indication associated with a feed item is received. In some instances, it is determined whether the feed item is associated with a custom rule, where the custom rule defines one or more actions to modify information associated with feed items of designated one more content types. In some instances, one or more actions are selected to perform based on an identified content type of the feed item in response to the determination that the feed item is associated with the custom rule.
