Abstract: In various exemplary embodiments, a system and an associated method for presenting a commerce application to an electronic device of an end-user. The method includes establishing electronic communications from the end-user to a first server (e.g., an electronic marketplace) in response to the end-user accessing a widget presented by the first server, and establishing electronic communications between the first server and a second server. The second server may be another electronic marketplace. The first server sends a chrome to the end-user. Substantially concurrent with the first server sending a chrome, the second server transmits electronically an Iframe to be placed within the chrome on a browser on an electronic device of the end-user. The blending of the chrome and the Iframe is transparent to the end user; thus, the end-user may be unaware that additional information (e.g., in terms of the Iframe and any accompanying metadata) is being received from the second server.

Abstract: Systems and methods for generating tokenized reputation scores are described. In one example, a service provider system receives data describing user activity associated with a service provider account and determines that the user activity is eligible for a reputation reward of reputation tokens. The service provider system initiates a calculation of the reputation reward based on the data describing the user activity. Further, the service provider system verifies a transfer of reputation tokens to a blockchain account address associated with the service provider account, where the reputation tokens are based on the reputation reward calculated. The service provider system generates a reputation score based on an amount of reputation tokens associated with the blockchain account address and generates an indication of the reputation score. The indication of the reputation score is displayed in relation to a representation of the service provider account.

Abstract: An experimentation platform controls testing of features by an application server. Based on a user identifier, the experimentation platform determines which feature should be provided, and the application server provides the corresponding version of a user interface. If the user behavior data shows that using a tested feature results in an improvement, the tested feature will be adopted. To determine whether or not an improvement is observed, a statistically significant amount of data is gathered. The experimentation platform gathers data regarding user behavior for the feature versions and, in response, adjusts the frequency at which each version is served. Providing the proposed version to an increased percentage of users decreases the total number of page serves required to gather statistically significant data. The experimentation platform may provide an updated projected time to completion of testing based on the changed percentage of users receiving the proposed version.

Abstract: Software is increasingly being developed as a collection of loosely coupled applications. Loosely coupled applications exchange data by publishing data to and retrieving data from a data store, such as a database, a file located on a storage cluster, etc. Data produced by one application and consumed by another is referred to as a data dependency. In some embodiments, an application's data dependencies are identified by analyzing cached query plans associated with the application. Query plans include a hierarchical representation of a query, where non-leaf nodes represent commands and leaf nodes identify data dependencies. An application's data dependencies are identified by traversing the hierarchical representation of the query. Data dependencies consumed by the application are identified by finding leaf nodes that descend from a read command, while data dependencies produced by the application are identified by finding leaf nodes that descend from a write command.

Abstract: Described are computing systems and methods configured to detect a small, but meaningful, anomaly within one or more metrics associated with a platform. The system displays visuals of the metrics so that a user monitoring the platform can effectively notice a problem associated with the anomaly and take appropriate action to remediate the problem. An operational visual includes a radar-based visual with a heatmap arranging metrics, and a node representing a state of the metrics. Moreover, the system uses an ensemble of unsupervised machine learning algorithms for multi-dimensional clustering of hundreds of thousands of monitored metrics. Via the visuals and the implementation of the machine learning algorithms, the described techniques provide an improved way of representing and simulating many metrics being monitored for a platform. Moreover, the techniques are configured to expose actionable and useful information associated with the platform in a manner that can be effectively interpreted.
