Versions of a service not reachable by a set of service requestors that use the service are removed. Multiple, different versions of a service are stored, along with metadata associated with the multiple, different versions of the service. The metadata is examined to determine one or more of the multiple, different versions of the service that are not reachable by the set of service requestors that use the service. Those versions are deleted.

A device for providing a messenger-based service may include a template message provider configured to provide a template message including a keyword slot; a keyword determiner configured to determine a keyword corresponding to the keyword slot by using an input message received correspondingly to the template message; and a result message provider configured to provide a result message including information corresponding to the keyword.

According to one embodiment, an apparatus is configured to communicate a first plurality of phishing emails to a first plurality of users, each phishing email of the first plurality of phishing emails is of a first type or a second type. The apparatus is configured to determine a first response rate of the first plurality of users to phishing emails of the first type and to determine a second response rate of the first plurality of users to phishing emails of the second type. The apparatus is configured to determine a second plurality of phishing emails comprising phishing emails of the first type and the second type, wherein an aggregate response rate of a second plurality of users to the second plurality of phishing emails is predicted to be closer to a target response rate than one or more of the first response rate and the second response rate.

A server according to one embodiment includes an information storage unit that store various types of information; a notification information transmission unit that transmits predetermined notification information to a terminal device of an invited user who is invited to a voice chat in response to receiving a voice chat initiation request from a terminal device of a requesting user; a state monitor unit that monitors whether the requesting user and the invited user are in an available state in which they are able to perform a voice chat; and a voice chat control unit that enables a voice chat communication between the terminal device of the requesting user and the terminal device of the invited user when the requesting user and the invited user are in the available state. The server serves as a voice chat management device that manages a voice chat between users who operate their terminal devices.

A method and messaging system comprising a master broker computer system, a plurality of slave broker computer systems, and a plurality of event stores, for a broker computer system to change its status from a slave broker computer system to a master broker computer system.

A nameserver receives a request to access a webpage from a client device. The nameserver generates a blockchain query based on the request for querying a domain registrar blockchain storing domain name registration data in smart contracts. The nameserver sends the first blockchain query to the domain registrar blockchain. In response to receiving a nameserver identifier from the domain registrar blockchain, the nameserver retrieves a DNS record for the webpage using the received nameserver identifier. The nameserver then provides information from the retrieved DNS record to the client device to allow the client device to access the webpage.

The invention provides, in some aspects, a system for rendering images, the system having one or more client digital data processors and a server digital data processor in communications coupling with the one or more client digital data processors, the server digital data processor having one or more graphics processing units. The system additionally comprises a render server module executing on the server digital data processor and in communications coupling with the graphics processing units, where the render server module issues a command in response to a request from a first client digital data processor. The graphics processing units on the server digital data processor simultaneously process image data in response to interleaved commands from (i) the render server module on behalf of the first client digital data processor, and (ii) one or more requests from (a) the render server module on behalf of any of the other client digital data processors, and (b) other functionality on the server digital data processor.

An electronic meeting tool and method for communicating arbitrary media content from users at a meeting includes a node configuration adapted to operate a display node of a communications network, the display node being coupled to a first display. The node configuration is adapted to receive user selected arbitrary media content and to control display of the user selected arbitrary media content on the first display. A peripheral device adapted to communicate the user selected arbitrary media content via the communications network is a connection unit including a connector adapted to couple to a port of a processing device having a second display, a memory and an operating system, and a transmitter. A program is adapted to obtain user selected arbitrary media content, the program leaving a zero footprint on termination. The user may trigger a transfer of the user selected arbitrary media content to the transmitter.
