Abstract: This Sampling Object Cache System (“SOCS”) estimates the size of an in-memory heap-based object cache without the need to serialize every object within the cache. SOCS samples objects at a user-determined rate and then computes a “sample size average” for each type of class—whether a top class, type of top class or non top class. Using these sample size averages, a statistically accurate measure of the overall size of the cache is calculated by adding together the total size of the objects in the cache for each class type.

Abstract: The invention provides an apparatus, system and method for allowing multiple television (TV) sets to communicate with each other in synchronizing their audiovisual signal output (when set to the same TV channel) to allow simultaneous viewing of common programming content.

Abstract: A method for providing secure access to a virtual machine includes dispensing an image corresponding to a virtual machine from a management appliance to a distributed computing system such that the virtual machine is implemented by at least one of a plurality of interconnected physical computing devices in the distributed computing system; establishing a trusted relationship between the management appliance and the virtual machine; and providing a user with access to the virtual machine from the management appliance without further authentication credentials from the user.

Abstract: An Ajax proxy indirection technique enables a local, front-end proxy server to handle Ajax requests from an Ajax client that must be serviced by an external Ajax server in an external domain, instead of a local Ajax back-end server exposing itself to the external domain. The front-end proxy server accepts the Ajax client's request and forwards it to the local Ajax back-end server. The proxy server asks the local AJAX server for the credentials to be used in the “external” AJAX request. The local Ajax back-end server then responds to the proxy server with meta-data for the external domain request that the proxy will make to the external domain. The proxy server uses the credentials of the “external” AJAX request to make the external request to the external Ajax server in the external domain. The proxy server performs any authentication and necessary domain mapping with the external Ajax server before sending a response from the external Ajax server back to the client.

Abstract: A method for allocating processing of an application performed by a computing system made up of a plurality of interconnected physical computing devices includes executing an application on a first application server associated with the computing system, the application having a number of modular software components; while executing the application, measuring processing resources consumed by one of the modular software components; and in response to one of the modular software components consuming an amount of processing resources defined by a criterion, deploying the one of the modular software components to a second application server associated with the computing system.

Abstract: A method of proactively monitoring the coherency of distributed cache. A cache comparison utility selects a set of cache keys from a replica cache connected to a main cache via a network. The cache comparison utility selects a first cache key from the set of cache keys and fetches a first cache value from the replica cache that corresponds to the first cache key. The cache comparison utility generates a first checksum value corresponding to the first cache value and the first cache key and stores the first checksum value in a first checksum table. The cache comparison utility creates a first total checksum value that corresponds to the first checksum table and compares the first total checksum value with multiple total checksum values that correspond to the main cache and one or more additional replica caches, thereby identifying replica caches that are not identical to the main cache.
