Abstract: Tracer objectives in a distributed tracing system may be compared to identify input parameters that may have a high statistical relevancy. An iterative process may traverse multiple input objects by comparing results of multiple tracer objectives and scoring possible input objects as being possibly statistically relevant. With each iteration, statistically irrelevant input objects may be discarded from a tracer objective and other potentially relevant objects may be added. The iterative process may converge on a set of statistically relevant input objects for a given measured value without a priori knowledge of an application being traced.

Abstract: Periodicity similarity between two different tracer objectives may be used to identify additional input parameters to sample. The tracer objectives may be individual portions of a large tracer operation, and each of the tracer objectives may have separate set of input objects for which data may be collected. After collecting data for a tracer objective, other tracer objectives with similar periodicities may be identified. The input objects from the other tracer objectives may be added to a tracer objective and the tracer objective may be executed to determine a statistical significance of the newly added objective. An iterative process may traverse multiple input objects until exhausting possible input objects and a statistically significant set of input objects are identified.

Abstract: A marketplace for monitoring services providers may configure and deploy monitoring and other services that meet a solution definition for a given application. The services may include monitoring and tracing, analysis, rendering, debugging, optimizing, load generating, and other solution providers. The solution definition may include a schema or other data definitions for parameters gathered during application execution, as well as definitions for parameters or solutions that may be desired. The marketplace may identify those services that may be configured to meet the solution definition, then configure and deploy the selected services. A financial clearinghouse may handle financial payments to the various service providers.

Abstract: A visualization system for a tracer may include a processing pipeline that may generate tracing data, preprocess the data, and visualize the data. The preprocessing step may include a mechanism to process user-defined expressions or other executable code. The executable code may perform various functions including mathematical, statistical, aggregation with other data, and others. The preprocessor may perform malware analysis, test the functionality, then implement the executable code. A user may be presented with an editor or other text based user interface component to enter and edit the executable code. The executable code may be saved and later recalled as a selectable transformation for use with other data streams.

Abstract: A force directed graph may serve as a part of a user control for a tracer. The tracer may collect data while monitoring an executing application, then the data may be processed and displayed on a force directed graph. A user may be able to select individual nodes, edges, or other elements, then cause the tracer to change what data may be collected. The user may be able to select individual nodes, edges, or groups of elements on the graph, then perform updates to the tracer using the selected elements. The selection mechanisms may include clicking and dragging a window to select nodes that may be related, as well as selecting from a legend or other grouping.

Abstract: A force directed graph may display recent activities of a message passing system as highlighted features over a larger graph. The force directed graph may display a superset of nodes and edges representing processes and message routes, then display recent activities as highlighted elements within the larger superset. The highlighted elements may display messages passed or computation performed during a recent time element of a time series. In some embodiments, the effects of activities may be displayed by decaying the highlighted visual elements over time.

Abstract: A force directed graph may display time series data using a set of playback controls to pause, play, reverse, fast forward, slow down, or otherwise control the display of the time series data. The playback controls may be used in a real time or near real time application to which data sets are displayed and the speed with which the data sets may be displayed. In one architecture, the force directed graph may be deployed using a rendering engine that receives data and renders the data into a graph. A playback controller may send updates to the rendering engine according to user inputs from the playback controls.

Abstract: A shower head having a plurality of nozzles capable of attachment to a flexible shower arm. The shower head has a unique nozzle construction that allows for the manipulation of an external flexible nozzle to remove mineral deposits and has an internal, rigid nozzle structure for efficiently forming an aesthetically pleasing water stream. The shower head may have two available flow configurations which are selectable by a valve.

Abstract: Inventory data, including time sensitive inventory data, are used to rank a list of choices presented at a point of sale terminal. Based on the ranked list of choices, the system and method may present one or more of the choices to the consumer through a ranked list, highlighting, promoting, or otherwise accentuating one or more choices. The system and method use a real time inventory system to evaluate the economic benefit for promoting a particular item contained in the ranked list.

Abstract: Disclosed are a device and method for searching and displaying of movie titles, as an aid to helping a customer of a video rental store find an appropriate movie title to rent. A kiosk may be located in the video rental store and available for a customer to search and preview movies. The kiosk may reference the customer's history of rented movies, a database of comparable movies, a database of popular movies, a database of the current inventory of the store, and other factors for providing a search result and other movies that may be of interest to the consumer. The use of the inventory of the current store in a search allows a retailer to offer promotions and special packages instantly while maximizing sales.

Abstract: A sawhorse is constructed with brackets allowing the legs of the sawhorse to fold into a compact unit by having the legs interleave when folded. The legs pivot about a plane that is canted to allow each leg to rotate without interfering with any other leg. The length of the legs are not restricted in any fashion. The legs may also be locked in both the extended, or service position as well as the closed position. The bracket may be constructed of as few as two unique parts, and a pair may be nested together for compact shipping, storage, and display on a store shelf.
