An apparatus, a method, and computer program product are provided that track build identifications of a project to determine when their associated files should be deallocated by a garbage collection system. The method includes receiving, by a continuous integration server, a payload from a source control management (SCM) system. The method also includes detecting at least one build identification (ID) within the payload and analyzing metadata contained within the payload to determine an adjustment to the reference counter for the build ID. The method further includes adjusting, based on the analysis, the reference counter relating to the build ID in a reference table, and passing the table to a garbage collection system for memory management purposes of the continuous integration server. The garbage collection system can then delete files associated with the build IDs that have reference counters at or below zero.

The present disclosure provides for sharing data structure values between applications via messaging in a computer operating system. A plurality of data structures are defined, each with a given topic name, and a data structure including a collection of defined formats of multiple data elements. Interest by applications in topics is registered. Within an application a collection of multiple data elements having the formats of a defined data structure are identified, and an item is stored in association with the given topic name of the defined data structure, where the item is a collection of data values of the identified data elements. The item is made available to an application registered to the topic for input of the values in a corresponding data structure in the application.

Sharing data structure values between software applications

Embodiments of the present invention provide a concept for determining the relevance of a tag within a post. Responsive to receiving a post composed by a first user and containing a tag referring to a second user, a post context based on a topic of the post, a user context based on a record of the first user and a tag context based on a record of the second user are obtained. The post context and the user context are compared to the tag context, and it is determined whether the tag is relevant to the post and the first user based on comparing the post context and the user context to the tag context.

Determining tag relevance

A computer system may modify the user interactions by receiving, by a computer system, a sequence of image frames in a time period, from a camera application on a mobile device, wherein the time period starts before and ends after a shutter is activated on the camera application; monitoring, by a computer system, movement of the mobile device within the time period; calculating a movement score for a user of the mobile device, by analyzing the sequence of image frames and the movement of the mobile device; and using the movement score to modify the user's interaction with the mobile device interface.

A method and apparatus. In response to a first mobile device not being connected to the broker service apparatus, it is ascertained that a second mobile device is connected to the broker service apparatus. A first control signal was received, prior to ascertaining that the second mobile device is connected to the broker service apparatus, by the broker service apparatus from a telephony service. The first control signal includes a first unique identifier and data targeted to the first mobile device. In response to the ascertaining, a second control signal is issued to the second mobile device in order to forward the data to the second mobile device. The second control signal includes an identifier of the first mobile device. The second control signal causes the second mobile device to use the identifier of the first mobile device to forward the data to the first mobile device.

Batch compression management of messages. A message being sent to a batch for transmission is intercepted. The message is assigned to a batch pool, in which multiple batch pools are provided as sub-sets of the batch. The assigning of the message to the batch pool is based on a similarity of properties of the message with other messages and determined by looking up the properties in a batch pool mapping database. The message is added to the batch pool or a new batch pool is created for the message. A batch pool of messages is compressed using a dictionary of the properties common to at least some of the messages in the batch pool. The compressed batch pools are transmitted over an input/output channel.

Batch compression management of messages

A method and system for verifying a user of a computer system are presented. One example comprises observing behavioral characteristics of the user's interactions with the computer system during a current session of computer system usage, the behavioral characteristics being based on command invocation behavioral characteristics. The example further comprises identifying variations between the observed behavioral characteristics and a behavioral profile developed based on prior command invocation behavioral characteristics of the user. A verification procedure for the user to complete to continue the current session is then implemented based on the identified variations between the observed behavioral characteristics and the behavioral profile.

Verifying a user of a computer system

Methods, computer program products, and systems are presented. The methods include, for instance: obtaining a native code having a large number of counters embedded for profiling. Use cases that is serviced by the native code is identified and respective use case profiles representing performance characteristics of a corresponding use case are created. Best predictors identifying one of the use case profiles are determined and variants for a production code is created with only the best predictors instead of the large number of counters. The variants are produced with the use case profiles to to a production environment for performing the use cases.

Static optimization of production code for dynamic profiling

According to one embodiment, a method for lossy data compression is provided. The method may also include determining a length and a plurality of bounding characters associated with each data item within the data message. The method may further include encoding each data item within the data message by replacing each data item with the determined length and the determined plurality of bounding characters. The method may also include transmitting the data message to a recipient.

Aspects of the present disclosure relate to managing power provided to devices. A first set of radio-frequency identification (RFID) power data can be read, by an RFID reader, from a first RFID tag of a first device electrically coupled to a power supply. The first set of RFID power data can specify a first amount of energy required by the first device if a power loss occurs. An indication that a power loss occurred can be received. In response to the indication that the power loss occurred, the power supply can provide the first amount of energy to the first device.

Controlling asynchronous tasks in a transaction system. A request to start an asynchronous child task is obtained, and a resource status of the system is determined. It is determined whether to suspend a parent task associated with the asynchronous child task or to execute the asynchronous child task based on the determined resource status of the system.

Controlling asynchronous tasks

Publish/subscribe messaging using a message structure carried out at a messaging intermediary system is provided. A plurality of lists to which publishing entities can publish messages and to which subscribing entities can subscribe to messages is maintained. A list for messages conforming, at least partly, to a common message structure is provided. A request from a publishing entity or a subscribing entity is matched to one or more provided lists by comparing a message having a message structure or an abstract representation of one or more messages to the provided lists. Messages conforming, at least partly, to the common message structure via the list are shared.
