Abstract: Collaborative help for user applications includes: generating a message, the message being reflective of a user's experience in using a user application; sending the message to a collaborative help server to share the message with other users; and receiving a response from the server providing information regarding one or more other users' experience similar to the user's experience reflected in the message.

Abstract: A method manages substantially continuous delivery of a data stream to a mobile communications device through sequential access thereby to respective receivers from a networked arrangement of wireless transceivers at known locations. A current location and velocity of the mobile communications device is determined. Based on a determined current location and velocity of the mobile communications device, a prediction for a next wireless transceiver to be accessed is generated, and a portion of the data stream is pre-cached at a predicted next wireless transceiver.

Abstract: A method apparatus and computer program product is disclosed for adding instrumentation to a body of code to enable generation of code coverage data for said body of code in which used instrumentation code is arranged to be optimized out by a compiler.

Abstract: A method of performing distributed just-in-time compilation includes sending a first request message from a client platform to a dedicated compilation server requesting just-in-time compilation of a bytecode sequence generated from a set of code for a source program executing on the client platform; compiling the bytecode sequence at the compilation server into a set of machine code instructions executable by the client platform; storing the set of machine code instructions in a repository managed by the dedicated compilation server; sending a notification message indicating that the set of machine code instructions are available from the dedicated compilation server to the client platform; sending a second request message from the client platform to the dedicated compilation server requesting the set of machine code instructions; and accessing the repository to send the set of machine code instructions from the dedicated compilation server to the client platform.

Abstract: A method and system for hosting an online virtual world system on game engine servers, is provided. One implementation involves obtaining a map representing a virtual world in the game, partitioning the map into multiple partitions, and selecting a game engine server for each partition as responsible for executing the game for detected game entities in that partition, wherein the selection is based on load balancing between the game engine servers.

Abstract: A method and apparatus for hosting a virtual world system including clients and game engine servers, is provided. One implementation involves providing a publication and subscription framework, interfacing the clients with the framework using a plurality of client proxies, interfacing each game engine server with the framework using a game engine agent, and decoupling the proxies from the game engine servers using the framework.
