A computer controls power distribution. The computing system determines a power budget for a portion of a topography for a power delivery system. The computing system generates a pool of worker programs for the portion of the topography. The computing system generates a first number of power management tasks to manage power consumption in the portion of the topography based on the power budget. The computing system sends the first number of power management tasks to at least one worker program included in the pool of worker programs.

Continuously available power control system

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.

Callee condition based communication with mobile devices

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.

Scalable self-healing architecture for client-server operations in transient connectivity conditions

A computer controls power distribution. The computing system determines a topography for a power delivery system that powers a group of computing devices. The computing system determines a number of worker programs for a pool of worker programs based on the topography. The computing system generates the pool of worker programs. The pool of worker programs includes both the number of worker programs and a number of back-up worker programs. The computing system generates a number of power management tasks to manage power consumption through one or more power elements included in the topography of the power delivery system. The computing system sends one or more power management tasks to a worker program included in the pool of worker programs.

A dynamic data distribution system allows publication of data values for hierarchical keys (paths) and subscriptions to key (path) patterns which include wildcard characters. Permission to publish or subscribe is controlled by an access control list associated with each key. An agent receives a publication request from a client, verifies client access permissions on the subject key, and transmits the publication to a data storage server which performs the write. Following a successful write, the agent forwards the publication to a message routing exchange which routes the publication to the session queue for all clients that are permitted to receive the publication and have subscribed to a key pattern matching this publication. For data synchronization, the data storage server assigns a virtual time stamp to each write, and the subscriber verifies the count of updates received for a subscription within a sliding window of virtual time stamps.

Dynamic distribution of persistent data

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.

Client-side fault tolerance in a publish-subscribe system

Each of a plurality of stations has a respective sequence of tracks of Internet content of common subject matter and a respective play pointer indicating a location in the sequence of tracks. In response to a first input, the presentation mode of the station is configured in a continuous play mode in which the play pointer is progressed through the sequence of tracks queued to the station regardless of whether or not the station is presently selected for presentation. In response to a second input, the presentation mode is configured in a pause play mode in which the play pointer is progressed through the sequence of tracks queued to the station only while the station is selected for presentation to a user and otherwise pauses progression of the play pointer. The processor transmits tracks of the station and progresses the play pointer in accordance with the configured presentation mode.

Personalized audio presentation of textual information

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.

Channel ownership in a publish-subscribe system

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.
