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: 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: 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 providing for display to a user a set of keys within a region of a touch-screen user interface, each key being responsive to a keystroke touch-gesture within an area of the key. The method also includes receiving a pre-defined user input other than a keystroke touch-gesture within an area of a key. The method further includes, in response to the pre-defined user input, providing within the region of the touch-screen user interface a trackpad in place of at least a portion of the set of keys.

Abstract: In one embodiment, a computing device receives input from a user participating in a message session. The computing device detects an emoticon in the received input and identifies an image corresponding to the emoticon. The computing device accesses the image corresponding to the emoticon and replaces the emoticon with the image in the message session.

Abstract: In one embodiment, a method includes providing for display a first set of touch-screen keys corresponding to a first set of symbols. The method also includes providing for display at least partially underneath the first set of touch-screen keys a second set of touch-screen keys corresponding to a second set of symbols. At least a portion of the second set of touch-screen keys are visible through the first set of keys.
