20140325498 | SELECTIVE OPERATING SYSTEM PATCHING/UPDATING - An application typically runs on top of an operating system. Some computing device have the ability to reboot and load a different operating system whenever an application or set of applications is run. If an old application requires an old operating system version, it is possible to load that OS instead. Every application can have its own version of the operating system. Only new applications or a small set of applications need to use the new OS—all the old applications may run their own older version of the OS. Patches or software updates can be applied only for particular applications. Other applications that need the same base OS but don't need the patch can skip using the patch. It is possible to determine what version the application is and selectively apply the patch based on the version of the application. | 10-30-2014 |

20110252152 | RELIABLE MESSAGING SYSTEM AND METHOD - A reliable messaging channel is created using multiple independent HTTP requests. In one embodiment, a method (a) establishes a session identifier by exchanging messages with a recipient using an application layer communication protocol (e.g., HTTP); and (b) uses the application layer communication protocol to send ordered data to the recipient by assigning one or more sequence numbers according to the predetermined order in the data. The session identifier may be generated, for example, using a random number of generator. In one implementation, the session identifier is not less than 96 bits long. The sender may receive from the recipient acknowledgements each acknowledging receipt of the data bearing a corresponding sequence number. Data to be sent in the opposite direction may piggy-back on an acknowledgement by including the data in a non-zero length payload. Data received out of order are queued. The sender may limit the rate at which data is transmitted to a “window size” (i.e., no more than a predetermined amount of data is sent within a predetermined time period). The window size is adjusted according to a channel condition (e.g., an amount of data retransmitted or lost during the predetermined time period). In one implementation, the window size is adjusted by doubling or halving, consistent with the channel condition. | 10-13-2011 |
