Abstract: In one embodiment, a method includes receiving a cover feed interaction history from a device associated with a user of a social-networking system. An order for a plurality of content boards may be determined based on the cover feed interaction history (e.g., viewing history, download status, the current order of content boards in the cover feed, user interaction history, whether the user bookmarked or pinned a particular content board), user information related to the user, and device information about device-based events and device status. Finally, the order for the content boards may be sent to the device. The determination of the order for the content boards may be based on the cover feed interaction history, recency of content included in the content boards, popularity of the content, relevance of content to the user, or device-based events.

Abstract: In one embodiment, a method includes determining a power consumption profile for each of multiple devices, where the power consumption profile includes information regarding a typical rate of power consumption by the corresponding device, and receiving status information for a first device of the multiple devices, where the status information includes power status and network connectivity status. The method also includes determining a schedule for sending push events to the first device using a resource-control algorithm, where the determining is based at least in part on a comparison of the power consumption profile for the first device with the power consumption profiles for one or more second devices and the status information for the first device. The method further includes sending the scheduled push events to the first device, where the push events provision content to the first device.

Abstract: A social networking system presents a viewing user with a newsfeed of stories describing actions performed by other social networking system users. In particular, the social networking system provides a pre-fetched set of newsfeed stories to a user device of the viewing user and a presentation order for the stories. The social networking system does not “lock” the set of newsfeed stories or the presentation order. The user device locally stores the pre-fetched ranked set of newsfeed stories upon receipt. When the viewing user later requests presentation of newsfeed stories, the user device retrieves the set of newsfeed stories and presents, to the viewing user, stories from the set according to the presentation order. A request is also sent to the social networking system to “lock” the presented newsfeed stories and the order in which the newsfeed stories were presented.

Abstract: In one embodiment, user information for a user of a social-networking system is retrieved. Device information is determined for a device associated with the user. Based on the device information or the user information, content associated with the user is retrieved. Using the retrieved content, a content board is composed for use in a cover feed displayed on the device The content board may comprise a background image. Finally, the content board is sent to the device. In one embodiment, updated information for content associated with the user is retrieved. The updated information may be associated with content that was included in a previously-provided content board. Using the updated information, an update to the previously-provided content boards is composed. Finally, the updates may be sent to the previously-provided content boards to the device.

Abstract: The present disclosure presents methods, systems, and devices for encrypting and comparing genomic data. The comparison of genomic data allows the owner of the data to ensure security of the data even when the party conducting the comparison is beyond the control of the owner of the data. The encryption of the genomic data enables the transmission, storage, and use of the genomic data in a secure media.

Abstract: In one embodiment, a method includes determining a power consumption profile for a device. Status information for the device may be received, wherein the status information comprises power status and network connectivity status. Using a resource-control algorithm and based on the status information and the power consumption profile, a schedule for sending push events to the device may be determined. Content to be provisioned to the device may be identified, and the scheduled push events may be sent to the device, in order to provision the identified content to the device. The resource-control algorithm may be further based on one or more device-based consumption factors, such as a periodic data usage transfer limit with respect to a specified network and a data usage status with respect to the specified network, or system-wide consumption factors, such as a power threshold that applies across all devices.

Abstract: A system, method, and computer program product for publishing transcoded media content in response to publishing service requests from end users. A user request for media content, is processed intelligently, either by directing the processing of the request to one of a set of transcoding servers so as to effectively balance the load among the servers, or by directing the processing of the request to an appropriate alternative means for satisfying the request. Transcoding tasks can be prioritized. Moreover, the current load on any particular transcoding server can be monitored in conjunction with determination of the load to be created by a transcoding task, in order to facilitate server selection. Transcoding can be performed on-demand or in a batch mode. Alternatively, a request can be satisfied by distributing media content that has already been transcoded and is resident in cache memory in anticipation of such requests.

Abstract: A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.
