Abstract: A method and apparatus for replicating a data container of a source storage server at the logical level in an unordered stream of individual data units are described. In certain embodiments, the replication operations can be performed without regard to the differences in geometry of physical persistent storage of the source and destination storage servers and without regard to the differences in data container format of the source and destination storage servers. An initial replication operation of the source data container is performed by transferring the data objects within the source data container to a replica data container in the destination storage server as an unordered stream of individual data units while preserving data object identifiers of the source data objects. Afterwards, incremental replication operations can be performed to capture modifications to the source data container over time after the initial replication operation.

Abstract: A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

Abstract: A system is disclosed that improves the ability for users to select links and/or other display elements via a touch screen, such as the touch screen of a smartphone, tablet, or other mobile device. The system achieves this effect by adjusting the sizes and/or shapes of the touch targets associated with particular display elements. For example, if a particular link on a web page is determined to be difficult to select via a touch screen (based on monitored user behaviors and/or based on an automated analysis of page content), the touch target associated with the link may be increased in size.

Abstract: Approaches enable three-dimensional (3D) display and interaction with interfaces (such as a webpage, an application, etc.) when the device is operating in a 3D view mode. For example, interface elements can be highlighted, emphasized, animated, or otherwise altered in appearance, and/or arrangement in the renderings of those interfaces based at least in part on an orientation of the device or a position of a user using the device. Further, the 3D view mode can provide for an animated 3D departure and appearance of elements as the device navigates from a current page to a new page. Further still, approaches provide for the ability to specify 3D attributes (such as the appearance, action, etc.) of the interface elements. In this way, a developer of such interfaces can use information (e.g., tags, CSS, JavaScript, etc.) to specify a 3D appearance change to be applied to at least one interface element when the 3D view mode is activated.

Abstract: An analytical system and method for periodically monitoring an injection water distribution pipeline for the presence and concentration of formaldehyde or other aldehyde-functional biocide includes pumps, one of which provides a predetermined volume of injection water drawn from the pipeline at a sampling point and another of which provides a predetermined volume of a reagent, preferably a buffered solution of dimedone, from a reagent storage vessel, wherein the injection water and reagent are mixed and then heated in a chamber to a predetermined temperature to promote formation of any reaction products. The heated reaction mixture is passed to a detection cell and exposed to light of predetermined wavelength which, in accordance with the Hantzsch reaction, molecules having an aldehyde functional group that reacted with dimedone produce a fluorescence-emitting reaction product, the intensity of which is measured and compared to data previously obtained from standard aldehyde-containing solutions.
