Abstract: Technologies are provided in embodiments to monitor and analyze networks. The embodiments can cause a bit in a first bit sequence of a device filter to indicate a failure state based on not receiving a message from a node in a network during a reporting time interval, and upon the reporting time interval expiring, to combine the first bit sequence with a corresponding bit sequence of a shadow filter. The combination preserves, in the shadow filter, an indication of the failure state from the bit in the first bit sequence and any other indications of failure states from bits of the corresponding bit sequence of the shadow filter. More specific embodiments cause, upon the reporting interval expiring, a bit in a second bit sequence of the device filter to indicate a no failure state based on an indication of another no failure state in the first bit sequence.

Abstract: In one embodiment, a method includes receiving, from a client system associated with a first user of the online social network, an indication of a check-in at a geographical location by the first user, generating multiple reaction-cards based at least in part on the check-in, each reaction-card being associated with a structured query referencing the geographical location, each reaction-card including one or more search results matching the structured query associated with the reaction-card. The method also includes sending, to the client system, in response to receiving the indication of the check-in, instructions for presenting one or more of the reaction-cards, wherein the reaction-cards are presented in ranked order based on a relevance of the structured query associated with the respective reaction-card to the geographic location.

Abstract: Updating computer program(s) installed on a programmable device using a distributed ledger that is based on cryptography and blockchain technology is described. A distributed ledger logic/module can commit, to the distributed ledger, a first configuration of a computer program installed on a device. The logic/module can also receive requests to apply a first update and a second update to the first configuration. The logic/module can receive a second configuration of the computer program that is based on the first update and the first configuration, and also commit the second configuration to the distributed ledger. Furthermore, the logic/module can determine that the second update cannot be applied to the first configuration and receive a third configuration of the computer program that is based on the second update and the second configuration. The logic/module can also commit the third configuration to the distributed ledger. Other advantages and embodiments are described.

Abstract: A server system obtains markup code for a native application for client devices. The markup code is agnostic regarding types of client devices. The server system translates the markup code into a set of primitives. Client devices of multiple types running a native application send a request for content for the native application to the server system. The server system provides the set of primitives to the client devices of multiple types, and the client devices render the set of primitives in the native application.

A method suitable for software implementation is presented in which indels may be readily identified in a computationally efficient manner.

Abstract: A method uses web servers to promulgate information from one server to another, instead of promulgating the information by the user to each server individually. A first server receives a first request for promulgating web-information from a user, locally promulgates the web-information, and sends a second request to at least one second website server to instruct the second website server to locally promulgate the web-information. The selection of the second server is done according to a preset configuration file which includes a relationship mapping between the first website server and the second website server. The relationship mapping may provide the user information related to the second website server based on the user information related to the first website server. The present disclosure further discloses a communication apparatus and a communication system.

Abstract: The present disclosure provides a method and apparatus for providing website authentication data for a search engine, the method comprising: receiving website authentication data from a plurality of authentication data sources; storing the website authentication data; and transmitting the stored website authentication data to the search engine when a request from the search engine for retrieving the website authentication data is received. By virtue of the method, the search engine may quickly retrieve complete website authentication data, thereby facilitating the search engine's search speed.

Abstract: An industrial visual stethoscope system and a detecting method are provided. The system has a base, a workpiece support, a single-color lighting device, a camera module, a rotating device, and an analyzing device. When the single-color light irradiates the workpiece, if the single-color light irradiates into the crack which is relatively deep and narrow, the single-color light is rarely to be reflected out of the crack. But if the single-color light irradiates into the scar, the single-color light is reflected out of the scar due to the specular reflection. During the relative rotation, when the reflected light enters the camera module in parallel, the energy of the light is concentrated, causing overexposure and forming obvious white light. Thus, the analyzing device can identify the recess is a scar formed by hit rather than a crack formed by heat.

Abstract: In one embodiment, a method includes accessing a social graph by a social-networking system. The social graph includes a plurality of nodes and a plurality of edges connecting the nodes. The social-networking system may receive a trigger action from a first user. In response to the trigger action, the social-networking system may generate reaction-cards based at least in part on the trigger action where each reaction-card is associated with a structured query referencing nodes and edges of the social graph. The social-networking system may calculate a reaction-card score for each reaction-card, where the reaction-card score is based on a relevance of the structured query associated with the reaction-card to the trigger action and user-engagement factors. The social-networking system may then send each reaction-card having a reaction-card score greater than a threshold reaction-card score to the first user for display on a page currently accessed by the first user.

Abstract: Techniques for repair and/or recovery of computer program(s) installed on a programmable device using a distributed ledger that is based on cryptography and blockchain technology are described. One or more self-reliance logic/modules can commit, to a distributed ledger that resides on interconnected devices, records of watchdog communications between the devices. One or more of interconnected devices may include a respective self-reliance logic/module. The logic/modules can use the records of the distributed ledger to check that computer program(s) on the interconnected devices are operating as expected. When a self-reliance logic/module fails to respond to a watchdog communication, the distributed ledger can be updated to include this failure. A self-reliance logic/module can determine, based on the distributed ledger and/or the failure, that an installed computer program is faulty. Furthermore, a self-reliance logic/module can initiate one or more software recovery services based on the determination.
