Abstract: A technique is disclosed herein for editing centralized digitally encoded content using a stateless client on a client machine. A repository on a central server is accessed by a user. The repository has a plurality of compilation units stored therein. One or more compilation units selected by the user are provided to the user via a stateless client on a client machine. The client is in communication with the repository over a network. Information associated with the one or more selected compilation units is programmatically sent to the repository at spaced time intervals.

Abstract: A method for visualizing web service interactions includes invoking a remote operation that causes a plurality of messages to be sent between two components in a connected system. The method further includes visually identifying a swim lane for each of the two components in a graphical display. For each message, a vector is plotted in the graphical display, where the vector extends from the swim lane of the message sender to the swim lane of the message recipient. The relative position of each vector depends on the time when the message was sent. A machine readable medium and an integrated development environment for representing asynchronous web service execution are also provided.

Abstract: Methods and apparatus are provided for controlling navigation guidance in a vehicle. The method includes: a) determining a re-route instruction based on a non-executed guidance instruction; b) presenting the re-route instruction; c) determining a non-execution of a re-route instruction; d) repeating steps a) through c) for a pre-determined number of re-route attempts; e) prompting for cancellation of navigation guidance after the pre-determined number of re-route attempts; and f) altering navigation guidance upon acceptance of the prompt for alteration.
