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.

Cost sensitive browser cache cleanup based on weighted probabilistic cached item usage

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.

Assigning user workloads to application servers

A method to authenticate an identity of a responder. The method includes receiving a request and determining, by one or more computer processors, a reviewer for the request. A custom key is generated for the reviewer and the request, and at least one URL is generated that contains the custom key. At least one URL is sent, along with the request, to the reviewer. Upon receiving a response to the request that includes a selection of one URL, it is determined whether the response was received from the determined reviewer for the request.

A system and method of controlling a portable radio may involve tuning a first receiver of the portable radio to a first broadcast from a first station, where the first broadcast includes specific program content. A switching event can be detected at the portable radio, where a second receiver of the portable radio may be tuned to a second broadcast from a second station in response to the switching event. The second broadcast can include the specific program content.

Program code generates on a first computer within a computer system a unique key for a computer software application, wherein the computer software application is on a second computer within the computer system. The program code generates on the first computer an authorization code that grants a designated end user access to implement a change to a configuration item on a second computer during a configurable time period. The program code verifies the authorization code inputted into the second computer to determine if the end user has authority to implement the change on second computer, wherein the authorization code is separated into a first string and a second string each having a fixed number of bits. The program code grants access to the end user to implement the change to the configuration item on the second computer if the end user has the authority to implement the change.

Techniques for assigning user workloads to application servers

A method and apparatus for locating errors is disclosed. A computer inserts an object reference into program code suspected of causing an error, the object reference having an initial class name. Responsive to execution of the program code, the computer generates a new class name for the object reference comprising the context information. The computer sets an object with the new class name as the object reference inserted into the program code suspected of causing the error, wherein the new class name of the object is located in computer memory in use by the executing program code. The computer then creates a record of the computer memory in use by the executing program code, the record including the context information in the form of the new class name of the object.

Identifying errors using context based class names

A first telephone number assigned to the first telephone is cryptographically hashed to generate a first message digest, and the first telephone sends a signal to a second telephone over a communication network, wherein the signal includes the first message digest. The second telephone receives the first signal and searches its contact records to determine whether a telephone number in one of the contact records generates a message digest that matches the message digest received. Then, in response to the second telephone determining that a telephone number in one of the contact records generates a message digest that matches the first message digest, the second telephone identifies the contact record that generates the matching message digest and provides audible or visual output of content from the identified contact record.

Enhanced privacy caller identification system

A method, system and computer-usable medium are disclosed for reducing overhead associated with exporting remote objects. A session context is generated when a remote or local session is respectively established by a remote or local client with a bootstrap remote object. The session context is then determined to be either remote or local and marked accordingly. If the session context is marked as remote, then the bootstrap remote object is exported as remote objects. However, if the session context is marked as local, then the bootstrap remote object is not exported as remote objects. Instead, they are provided for use by the local client as non-exported remote objects.

Method for optimizing remote object implementations

A system and method is disclosed that utilizes a Voronoi diagram to position and/or control perforated ventilation tiles in rooms of equipment requiring cooling air. The Voronoi sites used for constructing the Voronoi diagram are the air inlets of the equipment, and the Voronoi edges of the computed Voronoi diagram are used as the locations for placing (or controlling) perforated tiles.
