Abstract: To manage channel ownership in a publish-subscribe data processing environment, a determination is made at a first server that a subscription request from a client relates to a channel, the channel having a channel identifier. At an exchange component in a messaging middleware, a session queue associated with the client is bound to the channel. A mandatory delivery message is configured to be routed using a publisher identifier by the exchange component, the publisher identifier being related to the channel identifier. The mandatory delivery message is communicated from the first server to the exchange component to indicate an intent of the first server to become a publisher of the channel. The mandatory delivery message causes the channel ownership of the channel to be limited to a single publisher.

Abstract: To provide client-side fault-tolerance in a publish-subscribe system, a message is received on a channel from a server. At a function executing using a processor and a memory, a determination is made whether the message contains a heartbeat data. When the message contains the heartbeat data, a determination is made whether a content signature contained in the message matches a last known content signature saved from a previous message. When the content signature contained in the message does not match the last known content signature saved from a previous message, a refresh message is sent to the channel.

Abstract: Techniques are described for a real-time prioritization of service tasks. In one example, a method includes receiving one or more customer activity inputs associated with one or more service tasks for performing in a service establishment on behalf of customers of the service establishment. The method further includes receiving one or more metadata items associated with the one or more service tasks. The method also includes determining a prioritization of the one or more service tasks based on the one or more customer activity inputs, wherein determining the prioritization includes generating a prioritization value for the one or more service tasks based at least in part on at least one of the one or more metadata items or the one or more customer activity inputs, and updating the one or more service tasks based on the prioritization value.

Abstract: Disclosed embodiments provide an approach for sharing media items between mobile devices that are in proximity to one another. A device ID is generated and shared with nearby devices. Media items are uploaded to a data server and then sent from the data server to other devices that request them based on a shared device ID. Users do not need to know each other or be connected to each other in any social media sense, and yet can still share media items. Thus, disclosed embodiments provide a new level of crowd-sourced coverage of an event based on sharing of media items.

Abstract: For location-based communication with mobile devices, a condition is received, at a device associated with a caller, where the condition has to be satisfied by a callee at a past location, the past location being a place where different callees with different mobile devices are present at different times. At the device associated with the caller, an instruction is received for making a telecommunication call to a mobile device of a potential callee in a set of potential callees, where each mobile device associated with each potential callee in set of potential callees was present at the past location at a past time, and where each potential callee in the set of potential callees satisfies the condition at the past location. Using a processor and a memory in the device associated with the caller, the telecommunication call is initiated to mobile devices associated with a subset of potential callees.

Abstract: For current location-based telecommunication, an instruction is sent from a caller communication device to initiate a telecommunication with a set of destination communication devices. The instruction includes identifying information for a reference device but does not include any identifying information for the set of destination communication devices. Telecommunication data is received at the caller communication device from a destination communication device in the set of destination communication devices, where a server has established a communication channel between the caller communication device and the destination communication device based on a geolocation proximity of the destination communication devices relative to the reference device.

Abstract: For location-based communication with mobile devices, a set of callee conditions is received at a caller's device, which has to be satisfied by a callee according to information descriptive of a condition of the callee. The state information is distinct from the location and a time of the callee's presence at the location. An evaluation is made that each device associated with each potential callee in a first subset has been present at the location at a specified time, and that each potential callee in the first subset satisfies the set of callee conditions. At the caller's device, an instruction is received for making a telecommunication call to a device of a potential callee in a first subset. The call is initiated from the caller's device to mobile devices associated with the first subset of potential callees.

The mandatory delivery message causes the channel ownership of the channel to be limited to a single publisher.

Abstract: A respective sequence of tracks of Internet content of common subject matter is queued to each of a plurality of stations, where each of the tracks of Internet content resides on a respective Internet resource in textual form. In response to receiving a sample input, snippets of each of multiple tracks queued to a selected station among the plurality of stations is transmitted for audible presentation as synthesized human speech, where each of the snippets includes only a subset of a corresponding track. Thereafter, one or more complete tracks among the multiple tracks for which snippets were previously transmitted are transmitted for audio presentation as synthesized human speech.

Abstract: A method, system, and computer program product for scalable and self-healing architecture for client-server operations in transient connectivity conditions are provided in the illustrative embodiments. An application in a second system receives a request from a first system, the request requesting data from a type of service. A first response responds to the request. The request is queued in a service queue corresponding to the type of the service, to make the request available to a third system that provides the type of the service. A notification is received that a second response from the third data processing system has been posted into a session specific queue, the second response being responsive to the request. In response to another request received from the first system, a third response is sent to the first system, the third response including the data from the second response from the session specific queue.

Abstract: An instruction for making a call to a location is received at an application executing in a service provider system. The location is a place where different callees with different mobile devices are present at different times, and a callee is present with a mobile device at the place at a given time therefore the call is made to the mobile device of the callee in order to call the location. Using the application, a set of locations corresponding to a set of subscribers is detected. From the set of subscribers, a set of potential callees is identified. Each mobile device associated with each callee in the set of potential callees is present at the location at the given time. Using the application, the call is established between a caller's device and the mobile devices of a subset of potential callees, the subset of potential callees including the callee.

Abstract: A web site page has a reference for providing an address for a next page. The web site is crawled by a crawler program, which parses the reference from one of the web pages and sends the reference to an applet running in a browser. The address for the next page is determined by the browser responsive to the reference and is sent to the crawler. The crawler selects non-hypertext-link parameters from the web page of the web site server by performing a programmed action sequence, including selecting items from lists of the web page in a particular sequence. The crawler sends the applet running in the browser, for the query to the web server for the next page referenced by the one web page, the selected parameters and a context arising from the particular sequence.
