A computer implemented method and system for optimizing diagnostic data collection for a computerized issue tracking system. The method and system includes receiving a problem description from an origination system communicating with an issue tracking system. The problem description is analyzed for missing diagnostic data. A data collection scheme is identified to collect the missing diagnostic data. The data collection scheme is in accordance with a criteria for minimizing disruption of the origination system to collect the missing diagnostic data. The method and system includes communicating the missing diagnostic data to the issue tracking system.

For browser cache cleanup, to consider for eviction a data item stored in a cache of a browser application in a device, a probability that the data item will be needed again during a period after the eviction is computed. A type is determined of a network that will be available at the device during the period. A cost is computed of obtaining the data item over a network of the type, from a location of the device during the period. Using the probability and the cost, a weight of the data item is computed. The weight is associated with the data item as a part of associating a set of weights with a set of data items in the cache. The data item is selected for eviction from the cache because the weight is a lowest weight in the set of weights.

To identify a source of a memory leak in an application, a pattern of objects is identified in an object hierarchy of a heap dump, the pattern including an indication of the memory leak. The pattern is matched with a metadata of the application. A static entry in the metadata describes a relationship between a component of the application and an object of a class used in the component. A flow entry in the metadata describes a relationship between a pattern of instantiation of a set of objects corresponding to a set of classes and an operation performed using the application. When the pattern matches the flow entry in the flow section of the metadata, a conclusion is drawn that the memory leak is caused in the operation identified in the flow entry. A portion of a code that participates in the operation is selected for modification.

A system and method for reducing data usage for wireless subscription plans. An email and an attachment are downloaded to a first device of a first recipient. An attachment is identified on the email by an attachment processing service that ensures that sharing from the first device is based on a credit policy. That there is more than one recipient for the email and attachment is determined. That a second device of a second recipient is in the vicinity of the first device is determined. Verification of the second device is established with an email fingerprint exchange handshake based on a fingerprint of the email for the second recipient that is computed from a hash of content of the email, an identifier of the attachment, and an email id of the second recipient. A second network is utilized to copy the attachment from the first device to the second device.

A technique for assigning a user workload to an application server includes receiving a user request to initiate execution of a workload assigned to a user. An application server is selected, from among multiple application servers, to execute the workload based on compatibility between respective current states of the application servers and the workload.

A computer implemented method, apparatus, and computer usable program code for deploying packages. In response to a request to deploy a package for a software application containing metadata, a first portion of the metadata describing the package is processed. A second portion of the metadata relating to modification of a database is processed for the software application after processing the first portion of the metadata. A third portion of the metadata describing all other content for the software application is processed after processing the second portion of the metadata.
