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.

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

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.

Method and system are provided for management of a touchscreen interface of a device. The method includes monitoring touchscreen interface function by logging data relating to user interaction with locations of the touchscreen interface. The logged data is then analyzed to identify one or more areas of the touchscreen interface which are inactive. The remaining active areas of the touchscreen interface are modeled to form a modified touchscreen interface. An original touchscreen interface is then mapped to the modified touchscreen interface resulting in only use of the remaining active areas.

Method and system are provided for software application execution including switching between optimized code for use profiles. The method includes: accessing an application having multiple executables for the same function for multiple use profiles. The method includes: executing code for a first use profile; receiving a prompt to change to a second use profile; suspending the execution of the code for the first use profile; retrieving switching code from a pre-computed data structure, wherein the switching code is for carrying out operations to transfer from executing code for a first use profile to executing code for a second use profile; performing the operations of the switching code; and resuming executing the application by executing code for the second use profile.

A computer-implemented method includes a display. The display is for displaying a document, including a plurality of document parts. The method includes an image capture device. The method categorizes each of the plurality of document parts based on a content of each of the plurality of document parts. The method captures images of a user using the image capture device. The method determines a plurality of reading speeds for each of the plurality of document parts. The plurality of reading speeds based on the images of the user for each of the plurality of document parts. The scrolling speed for each of the plurality of document parts is based on the plurality of reading speeds and the content for each of the plurality of document parts. The method scrolls the document via the display based on the plurality of scrolling speeds for each of the plurality of document parts.

A method is provided for deforming one or more touch screen activation targets associated with respective representations of items displayed on a display of a touch screen device. The method includes: displaying one or more representations corresponding to each of the one or more items displayed on a display of a touch screen device; providing, for each displayed representation, an activation target defining boundaries within which a touch input is processed as corresponding to selection of the corresponding item; receiving information indicating the orientation or movement of the touch screen device; and responsive to the received orientation or movement information, deforming the activation target of the item with respect to the representation of the item. The items may be a plurality of keys forming a virtual keyboard; and each of the representations may be one of the plurality of keys on the display of the touch screen device.

The present disclosure relates to techniques for processing messages at an enterprise service bus in a distributed computing system. An example method generally includes receiving, at an enterprise service bus, a first message. The enterprise service bus uses a preprocessing agent to identify a message fragment, compute a hash value of the message fragment, and using the hash value as a key, to receive an existing parse tree from a cache. A parsing agent generates a message parse tree representing the first message, where the message parse tree incorporates the existing parse tree to represent the message fragment portion of the first message. A transforming agent generates a second message from the message parse tree where the second message has different format from the first message, the transforming agent transmits the second message to a receiving system.

Validation and parsing performance using subtree caching

Methods and systems are provided for processing messages for retrieval from a message queuing system. The method may be carried out at a message sending component, and may include: receiving requests from multiple clients, where a request includes at least one required record; forming a union of requests, such that a common record of multiple requests is handled once; providing the common record with an associated reference count of requests requiring the record, and associated metadata listing the client requests in the record; sending a record response to a queuing system when processed including the reference count and the metadata listing the client requests; determining when all records in a request have been sent; and notifying a client that the request can be retrieved from the message queuing system, including a response list indicating to the client the identifier of the requested records retained at the message queuing system.

A method of optimizing software source code, where the source code is for execution as compiled bytecode using a just-in-time compiler. The source code is compiled to generate corresponding compiled bytecode. The bytecode is then executed using a just-in-time compiler. Run-time optimization actions performed by the just-in-time compiler during execution of the bytecode are determined, and analyzed to determine corresponding optimization data for the source code.

Optimizing software code

Embodiments of the present invention disclose a method, computer program product, and system for recognizing patterns in log files with unknown grammar. A computer replaces one or more alphanumeric strings with a first alphanumeric character to generate a first resulting string. The computer then replaces one or more identical pairs of characters of the first resulting string with a second alphanumeric character to generate a second resulting string. The computer then replaces one or more consecutive instances of the second alphanumeric character, in the second resulting string, with one instance of the second alphanumeric character to generate a compressed string.
