A system for managing access to a shared resource includes a plurality of nodes is described. The system may determine a quota for each of a plurality of nodes in view of one or more factors associated with a respective node and set a local counter stored in a memory of each of the nodes to the value of the relevant quota. In response to a request to access a resource made by an end device, the system may serve the request with a first node in the nodes, wherein the local counter stored in the memory of the first node is more than zero, and decrement the local counter stored in the memory of the first node by one after serving the request. Synchronization data is sent from each of the nodes, including the value of the local counter stored in the memory of the relevant node.

An embodiment of the present application provides a user matching method, which includes: receiving first personal information sent by a current user; generating a first candidate peer information list according to the first personal information and providing the first candidate peer information list to the current user for selection; receiving at least one piece of first peer information selected by the current user from the first candidate peer information list; searching for a recommended user according to an information peer exchange principle, wherein the information peer exchange principle comprises that personal information of the recommended user matches with the at least one piece of first peer information selected by the current user, and the first personal information matches with at least one piece of first peer information selected by the recommended user; and providing information of the recommended user to the current user. A user matching apparatus is also provided.

Described are methods, systems and computer readable media for data source refreshing.

A computer program product having a computer readable non-transitory storage medium. The storage medium having encoded thereon a computer code for instructing at least one hardware processor to automatically: (a) intercept a plurality of data packets transported over a computer network; (b) analyze said plurality of data packets to identify at least one secure connection request to an unsecure domain hosted on at least one web server; (c) retrieve a digital security certificate for the unsecure domain from a trusted certification authority; (d) associate the digital security certificate with the unsecure domain, thereby converting the unsecure domain to a secure domain; (e) send the digital security certificate to at least one second client terminal. Thereby the computer program product facilitates a secure connection between the at least one second client terminal and the secure domain.

An account adding method is performed by a social networking application running at a mobile terminal when communicating with a second terminal (e.g., using a chat session). The method includes: recording voice information from the second terminal using the social networking application; extracting character string information and voiceprint information from the voice information; sending the character string information and the voiceprint information to a server; receiving an account that matches the character string information and the voiceprint information and that is sent by the server; and adding the account to a contact list of the social networking application. For example, the social networking application is started before starting a telephone call with the second terminal and the voice information is recorded during the telephone call.

Systems and methods for communicating data from off-vehicle data sources to a vehicle are provided. In one embodiment, a method for obtaining data for a vehicle comprises: initiating an information request from on-board a vehicle; formatting the information request onboard the vehicle into a data file format to generate a request file; performing a wireless file transfer of the request file from the vehicle to a data center, wherein the request file is transferred to a file system location; polling the file system location for creation of a response file corresponding to the request file; when the response file is detected within the file system location, retrieving the response file from the data center to the vehicle; and displaying at the vehicle information responsive to the information request from the response file. In some embodiments, the file system location is a file system location uniquely associated with the vehicle.

A system, a method, and a computer program product for scalable processes for write-order preserving data stream consumption. A data partition in a plurality of data partitions of data stream is selected based on a request received from a client processing node. The plurality of data partitions are distributed among a plurality of broker nodes in a distributed messaging system. A broker node in the plurality of broker nodes hosting the selected data partition is identified. The identified broker node provides the selected data partition to the client processing node for performing at least one function.

Systems and methods for neutral application programming interfaces are disclosed. In one embodiment, the disclosure relates to a system for neutral application programming interfaces. The system may comprise a device. The device may be configured to receive a request. The request may comprise an outer payload and an inner payload. The device may be further configured to parse the outer payload based on a common definition of the outer payload. The device may be further configured to extract information of an action from the outer payload. The device may be further configured to parse the inner payload based on a definition of the action. The device may be further configured to process the action.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing contextual information for a displayed resource that includes an image. In one aspect, a method includes providing, by a user device to a contextual information server, a query-independent request for contextual information relevant to an active resource displayed in an application environment on the user device, wherein the request specifies content of the active resource and further specifies that the active resource displayed on the user device includes an image, but does not include the image in the request, receiving a request for the image from the contextual information server, providing the image to the contextual information server, receiving a user interface element that includes contextual information regarding the image, and displaying the user interface element on the user device with the active resource.
