Abstract: An approach is provided in which a set of provision information is generated from a set of provisioners that are in process of fulfilling a client's provision request. The approach creates a set of provision events based on the set of provision information and, in response to detecting a failure of the provision request, the approach generates a provision chain from the set of provision events. The provision chain links the set of provision events based on correlation rules and identifies at least one isolation point of the failure. The approach informs the client of the at least one isolation point of the failure identified in the provision chain.

Abstract: A data storage system stores historical statistical data in a statistics hierarchy that is a tree of nodes. The data storage system receives a metric request from a remote requesting device through a Representational State Transfer (RESTful) Application Programming Interface (API), including a metric path that is a delimited list of list elements separated by delimiter characters. In response to an aggregation special character in the metric path, the data storage system i) obtains a category name immediately preceding the aggregation special character in the metric path, ii) identifies a branch of the statistics hierarchy indicated by the category name, iii) aggregates values of leaf nodes contained in the branch of the statistics hierarchy indicated by the category name that match a leaf type in the metric path to generate an aggregated value, and iv) transmits a metric response containing the aggregated value to the remote requesting device.

Abstract: Methods, systems, and apparatus for optical communications. One of the apparatuses includes a spool comprising a spool wheel, one or more separate spool portions positioned on the spool wheel, and one or more bearings positioned on the spool wheel, wherein the one or more spool portions and the one or more bearings are configured such that an optical fiber ribbon can be wound through the spool; and a spring coupled to the spool wheel such that the spring provides a rotational force on the spool in a direction that winds the optical fiber ribbon.

Abstract: Embodiments relate to preview serving of content previews from a preview service for a component having associated content. A filter of a layered preview service executing on a processor receives a request from a client consumer for a feed from the component. The filter identifies a content reference returned by the component in response to the request for the feed. The filter establishes an association between the content reference and a user identifier of the client consumer as an authorization record. A preview service receives a preview request including the user identifier and a content identifier. The authorization record is checked to determine whether the content identifier matches the content reference for the user identifier. A content preview of the associated content as identified by the content identifier is served based on determining that a match exists.

Abstract: A power amplifier with noise shaping function is provided. The power amplifier includes a differential mode integrator, an integration and adjustment unit and a switch unit. The differential mode integrator is used for receiving a differential mode input signal and a differential mode output signal, and outputting a differential mode first signal. The integration and adjustment unit is coupled to the differential mode integrator for receiving the first signal and an output signal and outputting a single-end mode second signal. The switch unit is used for receiving the second signal and outputting the differential mode output signal to drive the load. The present invention uses a common mode input signal instead of the single-end input signal to eliminate the common mode noise, and uses a 2nd-order (or more than that) integrating circuit instead of the conventional filter to achieve a preferred effect of reducing the off band noise.
