A method, system, and computer program product that includes a processor assigning a network connection to an application, based upon the application requesting the network connection from a pool of network connections for connecting applications to a network resource, the assigned network connection for communicating a message with the network resource. The processor replaces the assigned network connection in the pool with a placeholder comprising configuration data of the assigned connection. The processor determined a period of inactivity of the assigned network connection, and the processor returns the assigned network connection to the pool, based upon the period reaching a defined threshold of inactivity.

Embodiments of the present invention disclose a method, computer program product, and system for class splitting in object-oriented environments in which objects are created by classes. Data is analyzed, in response to generating an instance of an original class in a code component. Fields are separated into sets based on the code paths that access the fields. A split class is generated for a set of fields which shares a common interface with the original class. Cells are replaced in the code component to the original class with a split class.

A system connected to an existing computer includes a unit for monitoring the screen and provides input, a storage unit that stores data that pairs screen buffer regions with authentication details, wherein the system learns new pairs via user training and presents stored authentication details when the screen buffer regions match a related stored region which is paired with a region of the screen, and a unit that determines which of stored passwords need to be presented to the system by a pattern matching of regions of screen pixels.

Automated password authentication

Providing feedback on a musical performance performed with a musical instrument. An instrument profile associated with the musical instrument used to perform the musical performance is identified. The instrument profile comprises information relating to one or more tuning characteristics of the instrument. The pitch of notes of the musical performance are analyzed based on the instrument profile to determine a measure of tuning of the musical performance. A feedback signal is generated based on the determined measure of tuning.

A method and computer program product is disclosed for managing a message broker and subscriber application programs in a publish/subscribe messaging system so as to maintain the state of the subscriber application program on the broker subscriber application program.

Managing a message subscription in a publish/subscribe messaging system

A publish/subscribe messaging network in which a distributed set of publish/subscribe brokers comprises a first subset of publish/subscribe brokers, each arranged to store proxy subscription information for the whole of the distributed set of brokers; and a second subset of publish/subscribe brokers, each configured to send subscription information for local subscribers to one or more brokers within the first subset of publish/subscribe brokers, and configured to request, from a broker within the first subset of brokers, proxy subscription information following receipt of a message.

Scalable publish/subscribe messaging systems and methods

An apparatus for validating a value of a variable data item in a software routine in execution includes a profile set generator that generates a profile set of typical values of the variable data item, a profile rule generator that generates a profile rule representing the profile set, and a profile checker that determines if a value of the variable data item satisfies the profile rule.

Validating a variable data item in a software routine

Improving scalability and throughput in publish/subscribe messaging systems by allowing the spoke systems to vary the member of the hub collective that it attaches to. The scalability is improved because the spoke systems do not have to have a long lasting attachment to a specific hub system. Instead, the spoke systems can be redistributed more evenly when new spoke systems are added or removed. The throughput is increased by distributing workload and fan-out responsibilities within hub collectives. Availability is improved because single points of failure are removed. Ease of administration is also improved over a hierarchy by allowing child nodes to automatically change parent nodes if a parent node is modified or removed.

Improving scalability and throughput of a publish/subscribe network

A method of automated password authentication by pattern matching regions of screen pixels against a repository of previously captured regions, and submitting a username and a password stored with the regions of the screen pixels for authentication includes triggering an autorunnable application to startup by inserting a memory stick by a user, challenging the user for a master password to access an encrypted database held on the memory stick, running the autorunnable application as a background task following a successful authorization of the user, and checking whether the user has triggered the autorunnable application by a pre-defined key sequence. If the user has triggered the autorunnable application, then the method proceeds with prompting the user to highlight at least one rectangle around a text or an image which uniquely identifies a login panel, capturing a username and a password when entered by the user, and returning the autorunnable application to a background task. If the user has not triggered the autorunnable application, then the method proceeds with monitoring a screen buffer for a matching signature based on the rectangle drawn by the user.
