Abstract: A client device accesses an online system using an authentication process when it is connected to a public network and not a private network. The client device requests access using an authentication broker via the public network. The authentication broker determines an authentication system and transmits identification information for the client device to the authentication system via the private network. The authentication broker receives an authentication vector generated by the authentication system via the private network, and receives a verification response from the client device via the public network. The verification response corresponds to a verification challenge generated based on the authentication vector by the authentication broker. The authentication broker determines the client device is authorized to access the online system based on the authentication vector and verification response and transmits an authorization to the client device via the public network allowing access to the online system.

Abstract: In one embodiment, a method includes sending, by a client device, a request to a computer server system for a target structured document. In a first response phase, a first response portion from the computer server system is sent in response to the request. The first response portion includes a first resource associated with the target structured document, wherein a likelihood that the first resource will be included in a response to a future request for the target structured document exceeds a first predetermined threshold. Further in a second response phase, a second response portion from the computer server system is sent in response to the request. The second response portion includes a second resource associated with the target structured document, wherein a likelihood that the second resource will be included in a response to a future request for the target structured document exceeds a second predetermined threshold.

Abstract: A method of performing equalization of audio signals to be provided to the speakers of a client device is based on determining a target position for the client device in the environment. Sensors in the client device may capture data of the environment. The sensor data is analyzed to determine location information associated with one or more target individuals in the environment. Audio signals that are to be provided to an audio output system of the client device are equalized based on the target position to compensate for an expected loss in the audio signal between the client device and the determined target position. The equalized audio signals are provided to the speakers of the client device for audio playback.

Abstract: Various client devices include displays and one or more image capture devices configured to capture video data. Different users of an online system are associated with client devices that exchange information captured by their respective image capture devices. A user of a client device may provide a message to an additional user of an additional client device for asynchronous presentation to the additional user. The message includes information identifying the additional user and one or more privacy settings. When the additional client device identifies the user via captured video data, the online system determines whether the message has previously been presented to the additional user. Subject to the privacy settings included in the message, the additional client device presents the message to the additional user after detecting the additional user and determining the message has not previously been presented to the additional user.

Abstract: In one embodiment, a method includes receiving from a client system a search query, identifying a first place-entity based on the search query, accessing a place-entities graph comprising a plurality of place-entity nodes, each place-entity node representing a particular place-entity associated with a particular geographic location, wherein the first place-entity is represented by a first place-entity node, accessing a redirection graph comprising the plurality of place-entity nodes and a plurality of place-entity clusters, each place-entity node in a place-entity cluster having a redirection edge connecting the place-entity node to a canonical place-entity node of the respective place-entity cluster, and sending a response to the search query, wherein if the first place-entity node is connected to a canonical place-entity node by a redirection edge within the redirection graph, the response comprises a reference to the canonical place-entity node, else the response comprises a reference to the first place-entity node.

Abstract: A floating-point number in a first format representation is received. Based on an identification of a floating-point format type of the floating-point number, different components of the first format representation are identified. The different components of the first format representation are placed in corresponding components of a second format representation of the floating-point number, wherein a total number of bits of the second format representation is larger than a total number of bits of the first format representation. At least one of the components of the second format representation is padded with one or more zero bits. The floating-point number in the second format representation is stored in a register. A multiplication using the second format representation of the floating-point number is performed.

Abstract: An online system presenting content items to a user generates a model that predicts a latent metric describing user actions that occur at least a reasonable amount of time after presentation of content items. To determine the latent metric, the online system retrieves one or more models predicting likelihoods of the user performing various interactions when presented with the content items and determines weights associated with different retrieved models. Combining the weighted retrieved models generates a model for determining the latent metric. As the retrieved models are based on data accessible to the online system in less than the reasonable amount of time after presenting content items, weighing the retrieved models allows the online system to predict the latent metric describing user actions occurring after content items are presented. When selecting content items for the user, the online system accounts for the latent metric determined by the generated model.

Abstract: An online system may identify content with which a user has an interest. For example, the online system may determine that a user has an interest in the content based on interaction information indicating that the user interacted with the content. In a particular example, the online system may identify image concepts included in the content based on computer vision techniques that recognize the image concepts. The online system may model probabilities that image concepts will appeal to users. Based on the modeled probabilities, the online system may automatically recommend image concepts for inclusion in candidate images, automatically generate candidate images, or assess candidate images to determine a probability of user interaction with the assessed candidate images.
