Abstract: Disclosed are various embodiments for transmitting a plurality of files of a plurality of file systems associated with a corresponding plurality of users to each one of the users. In one embodiment, a jukebox service identifies files from file systems associated with each user requesting to consume the transmitted content. In one embodiment, the jukebox service identifies the files based in part on a plurality of disc jockey preferences provided by a disc jockey. The jukebox service then generates a jukebox playlist of the identified files having an order that is generated based at least in part on a playback profile associated with each one of the files. For instance, the playback profile may describe a playback frequency of the respective file. The jukebox service may then transmit the files over a network to clients of requesting users according to the order established by the jukebox playlist.

Abstract: Disclosed are various embodiments for replicating service requests. A service request is obtained from a client. A primary service and a secondary service are determined based at least in part on the service request and a routing configuration. The secondary service corresponds to another version of the primary service. The service request is routed to the primary service and potentially replicated to the secondary service. A service response to the service request is obtained from the primary service and then sent to the client.

Abstract: Disclosed are various embodiments for facilitating a user to design and test a layout to a network merchant site. One embodiment of such a method describes presenting at a display device a graphical interface to edit a layout of a network page in at least one graphical pane; receiving a selection of parameters to a trial experiment of one or more modifications made to the layout of a version of the network page designed in the graphical pane(s); and tracking at least one metric for the version of the network page designed in the graphical pane(s) based on interactions with the first sample class of users.

Abstract: In accordance with one or more aspects, multiple folders are generated each corresponding to one of multiple levels of an image pyramid, and each of the multiple levels including one or more tiles. In each of the multiple folders, one or more files are stored, each file including image data for a tile of the level corresponding to the folder. In accordance with other aspects, a first version of an image is generated, the first version of the image having a lower resolution than the image. The image is compressed using a first compression process, and the first version of the image is compressed using a second compression process, the second compression process being a higher quality process than the first compression process. Both the compressed image and the compressed first version of the image are stored as an image pyramid for the image.
