In an approach, a processor detects at least one training message delivered by a user on a social media application, the training message being accessible by an operator. A processor records training feedback performed by the operator on the social media application regarding to the at least one training message. A processor trains an analysis engine module using (i) the at least one training message as input and (ii) the training feedback as output. A processor generates a predicted feedback for a subsequent message based on the trained analysis engine module.

Feedback prediction in a social media application

According to one embodiment, a method, computer system, and computer program product for memory corruption diagnosis is provided. The present invention may include generating a pattern expression (PE) header file, wherein a plurality of common datatypes associated with a software program are pre-defined. The invention may further include generating a PE for each of the plurality of common datatypes, and generating a PE table by merging the generated PEs for each of the plurality of common datatypes. Upon discovery that memory corruption has occurred, the invention may include transmitting a recorded state of the software program as a core dump file to a server, and using a dump utility to identify overlay content of the core dump file. Lastly, the invention may include identifying a possible source program of the memory corruption by matching the PE tables against the illegally-written overlay content.

Problem diagnosis technique of memory corruption based on regular expression generated during application compiling

Embodiments of the invention provide methods, systems, computer program products for managing a call waiting in a queue during a request for staff services provided by a call center. According to the method, a first voice segment received in a call made by a device is recorded first. Next, whether a part of the first voice segment is related to a first predefined voice segment is determined. The volume of device is adjusted in response to the part of the first voice segment being related to the first predefined voice segment. A user of the device is alerted in response to the part of the first voice segment being not related to the first predefined voice segment.

Optimization for a call that waits in queue

A file is transmitted to a plurality of hosts. The hosts are divided into host groups. A host in each host group is selected as a master host. A data block is received by a master host in a host group. The master host sends the data block to both a master host in a next host group and a next host in the host group in order that the next host in the host group sends the data block to a next host of the next host in the host group, and the master host in the next host group sends the data block to both a master host in a next host group of the next host group and a next host of the next host in the next host group.

File transmission in a cluster

A system, method, and computer product for managing a password includes receiving a new password set by a user via a key input interface, generating a diagram based on key positions, on the key input interface, of a plurality of characters associated with said new password, storing a diagram into a memory device coupled to the processing device, and providing said diagram stored in the memory device to the user as a password hint.

Password hint generation mechanism

A mechanism is provided for identifying a performance bottleneck of a transaction in a transaction processing system. At a predefined time point, status information of an interaction between the transaction and a processing component among one or more processing components in the transaction processing system is collected. A duration of the interaction on the basis of the status information is determined. In response to the duration exceeding a predefined threshold, the interaction is identified as the performance bottleneck of the transaction in order to make changes to the transaction processing system thereby improving performance.
