Abstract: Using persistent party rooms, including: initializing, via a computing device, a global array according to a hierarchical server architecture; determining, via the computing device, whether or not to create a new persistent party room or to join a previously bookmarked persistent party room; creating, via the computing device, the new persistent party room within a position indexed in the global array; and joining, via the computing device, the previously bookmarked persistent party room by searching for the previously bookmarked party room utilizing the global array.

Abstract: In an embodiment, a method includes identifying, in a defragmentation scheduling logic of a first system of a data center, a first virtual machine (VM) of a first server of the data center to select for migration based on a cost determined according to a source algorithm, identifying a second server of the data center to select for receipt of the first VM based on a cost determined according to a destination algorithm, where the second server has available free space to receive the first VM and the available free space has been scrubbed prior to the identification, and migrating a substantial plurality of VMs between servers of the data center based on cost according to the source and destination algorithms, to defragment the data center.

Abstract: A portable electronic device comprises a display facing in a first direction, a video camera facing in a second direction substantially opposite to the first direction, and a wireless communications receiver operable to receive supplementary image data from a remote image source, the supplementary image data comprising an indication of where a supplementary image is positioned with respect to a reference image. The portable electronic device is arranged in operation to display a captured image from the video camera on the display of the portable electronic device. When the captured image comprises all or part of the reference image as displayed on a separate display associated with the remote image source, the portable electronic device is arranged in operation to display the supplementary image positioned with respect to the reference image, instead of the corresponding part of the captured image.
