    Abstract: A device determines, based on location verification data that has been received, that the device is indoors at a first geographic location. The device determines a base measured barometric pressure, and an initial floor that the device is located on in a structure that includes the first geographic location. The device determines an adjusted measured barometric pressure for a second geographic location based on a second measured barometric pressure for the second geographic location and one or more reference barometric pressures that are associated with a reference location. The device determines an altitude for the second geographic location based on the base measured barometric pressure and the adjusted measured barometric pressures. The device causes a server to predict a floor that the device is located on at the second geographic location and to provide floor data that identifies the floor to an interface that is accessible to the device.

    Abstract: A device receives a user election of participation in a distributed cache service, and receives user selection of one or more devices, that are each associated with the user, to register with the distributed cache service as participant nodes. The device determines an amount of available storage offered to the cache service for each of the one or more participant nodes, and determines an available bandwidth of a respective network connection associated with each of the one or more participant nodes. The device admits selected devices of the one or more participant nodes into the distributed cache service based on the available storage and the available bandwidth, and interleaves storage of multiple chunks of content across a subset of the participant nodes admitted into the distributed cache service. The device enables client access to the multiple chunks of content interleaved across the subset of the participant nodes.
