In one embodiment, a server computing device receives a message indicating a current notification mode of a mobile computing device of a user. The received message comprises information from one or more sensors of the mobile computing device. The current notification mode is based at least in part on the information from the one or more sensors of the mobile computing device. The activity of the user is determined based at least in part on sensor information of the mobile computing device. The current notification mode of the mobile computing device is determined based on the user activity or the information from the one or more sensors of the mobile computing device. The server computing device determines whether to transmit a communication to the mobile computing device based on the current notification mode of the mobile computing device.

Device actions based on device power

Particular embodiments of a gateway computing device may provide a provisioning service for access credentials for a restricted network. The gateway computing device may receive, from a client device, a request for the access credentials, wherein the request was sent over an open network using a restricted-packet-size protocol designed to limit power usage by devices sending messages using the protocol. The gateway computing device may segment data comprising the access credentials into a plurality of packets, wherein the plurality of packets conform to the restricted-packet-size protocol. Finally, the gateway computing device may send, over the open network to the client device, the segmented data using the restricted-packet-size protocol.

Managing a device cloud

In one embodiment, a method includes receiving a command message from a client device associated with a user; parsing the command message; identifying, based on the parsed command message, one or more of a number of connected devices; determining, based on the parsed command message, one or more instructions for the identified connected devices; and providing the instructions to the identified connected devices.

Controlling a device cloud

In one embodiment, a method includes determining one or more bandwidth constraints on a bandwidth of a communication channel available to a first computing device; determining a plurality of data items to transmit from the first computing device; ranking each data item based at least in part on an affinity between a user and an originator of the data item in a social-networking system; selecting, based at least in part on the ranking of the data items, one or more particular ones of the data items to transmit from the first computing device from the first computing device; and writing the particular ones of the data items to a queue for subsequent transmission.

Content prioritization based on packet size

Particular embodiments of a gateway computing device provide a provisioning service for access credentials to a restricted network, wherein the provisioning service is accessible by an open network. A messaging protocol for the open network may only recognize messages relating to one of a set of services provided by the gateway computing device, including the provisioning service. The gateway computing device may receive, from a client device, a request to connect to the restricted network, wherein the request was sent using the open network. Upon determining whether the client device is authorized to access the restricted network, the gateway computing device may send a response to the client device using the open network.

In one embodiment, a method includes receiving a natural-language message including an authorization request to authorize a first user access to one or more of a number of connected devices associated with a second user; parsing the natural-language message; identifying, based on the parsed natural-language message, the first user and one or more of a number of connected devices; implicitly determining that the first user is authorized to access the identified one or more of the number of connected devices based on a calculated strength of a relationship between a node representing the first user in a social graph and a node representing the second user in the social graph satisfying a pre-determined threshold; and providing, based on the implicit authorization, access to the identified one or more of the number of connected devices.

In one embodiment, a method includes receiving notifications of events associated with the connected devices, evaluating a plurality of event sequences that include two or more events occurring within a particular time period, and generating a plurality of rules based on the evaluated event sequences. The method further includes receiving a notification of a first event associated with a first connected device on the network, determining that a first rule of the plurality of rules is based on the first event, and sending one or more instructions to connected devices in accordance with the first rule.

Rules engine for connected devices

In one embodiment, one or more computing devices determine, substantially in real time and locally at a mobile device, one or more current dynamic operating conditions of the mobile device related to energy consumption by the mobile device. The computing devices identify a pre-determined device state that corresponds to the current dynamic operating conditions of the mobile device and determine, based at least in part on the pre-determined device state, an action for the mobile device to take, the action being related to energy consumption by the mobile device.

In one embodiment, a method includes a server receiving activity data from a plurality of computing devices, wherein the activity data is associated with running a particular application; identifying, based on the activity data, a pattern of execution related to executing one or more sequences of instructions associated with running the particular application; determining, based on the pattern of execution, a clocking policy for running the particular application, wherein the clocking policy is configured to modify a clock speed of one or more processors of a particular computing device while running the particular application; and sending the clocking policy to the particular computing device.

Processor clocking policies for mobile computing devices

In one embodiment, a first computing device determines a number of data packets available to transmit from the first computing device to a second computing device. The determination is based on an available bandwidth and a payload capacity, and each of the data packets has a payload with the payload capacity. The first computing device determines a plurality of data items to transmit from the first computing device to the second computing device. The first computing device then ranks the data items and selects, based at least in part on the ranking of the data items and the payload capacities of the data packets, one or more particular ones of the data items to transmit from the first computing device to the second computing device in the data packets. The first computing device writes the particular ones of the data items to the payloads of the data packets.

In one embodiment, a processor of a computing device executes a sequence of instructions that depends on one or more external operations. Software of the computing device determines a clocking policy for the processor during execution of the sequence of instructions. The clocking policy is based at least in part on a pattern of execution involving the sequence of instructions and the external operations, and the clocking policy modifies a clock speed of the processor. The software of the computing device applies the clocking policy to the processor during execution of at least a portion of the sequence of instructions.

Systems, methods, and non-transitory computer-readable media can receive an indication that a drive included in a set of drives has experienced an error. Acquiring first data associated with the drive can be attempted. The drive can be prompted to undergo a power-cycle. Acquiring second data associated with the drive can be attempted. At least one of the first data or the second data can be analyzed to determine that the drive is remediable. At least the drive included in the set of drives can be remediated, such as by being rebuilt or reconfigured.
