An electronic book distribution system includes electronic devices that reset their passcodes after specified authentication failures. The passcodes of an individual electronic device is reset to a value that is generated using a predefined function of a randomly generated support code. The support code is displayed to the user, and the user is instructed to contact a support service in order to obtain the new passcode. The support service independently authenticates the user, calculates the new device passcode using the same predefined function used by the electronic device, and provides the new passcode to the user.

Assigning new passcodes to electronic devices

A machine-readable code rendering device may include an electronic paper display and a machine-readable code rendering module that dynamically renders machine-readable codes on the electronic paper display. The electronic paper display may be configured so that the machine-readable codes are read by a light-based code reader off of the electronic paper display.

A sharing service receives a request to store a media item stored on an electronic book reader device for sharing with one or more other content rendering devices. In response, the sharing service associates a pass phrase with the request. The sharing service then provides the media item to those devices (e.g., eBook reader devices) that provide the pass phrase to the sharing service within a predetermined amount of time.

Sharing media items with pass phrases

A windowing system for an electronic device that uses an electronic paper display may include a compositor, a frame buffer, and a display controller manager. One or more applications running on the electronic device may request multiple changes to windows. The compositor may determine multiple update areas, where an update area indicates the smallest area of the electronic paper display that should be updated as a result of changes being made to a window. The update areas may be stored in the frame buffer. The display controller manager may create a cumulative update area based on the update areas that are determined between a begin update instruction and an end update instruction. The display controller manager may instruct a display controller to update only the portion of the display corresponding to the cumulative update area.

Tools and techniques for creating presentations via dynamic digital content (DDC) tools using a display dependent markup language interface facilitating dynamic content are described. The markup language, 'DXyml', identifies content elements, including dynamic content elements, for display and specifies pixel locations at which to position the content elements on a client device. Pixel locations are selected for particular screen configurations, allowing the presentations to be created in advance of being served to specific types of devices with the particular screen configurations.

A method and a structure for providing electronic mail, facsimile transmission and file transfer maintain a data base in which the communication parameters of a local computer are maintained separately from the communication parameters of a remote computer which communicates the local computer. The data base includes an electronic address book in which a method and a structure are provided for specifying person, group, computer, calling card and service data. The person type data includes specification of a preference for data, or facsimile transmission. Service information are efficiently added because of modularly designed application programming interface. A method and a structure are also provided to allow synchronization between files residing on different computers.

A window server communicates with clients and creates, destroys and modifies window objects. Objects are created in response to parameters provided by clients. Clients can obtain a variety of information regarding windows managed by the window server. Hardware windows are supported by subclassing objects, which provides polymorphic screen objects. Therefore, it does not matter whether the window is created by a hardware or software entity. Clients may be notified by the window server in response to certain events occurring with respect to particular windows, such as a configuration change. The window server also dynamically manages a default window layering scheme which takes into account the parameters specified, or not specified, by clients as well as the characteristics of the windows currently being managed by the window server. The window server also supports window clustering, which allows a window to span monitors. The window server also allows extensive changes to the characteristics of the desktop in response to configuration programs.
