Abstract: Techniques for detecting software regression in computing systems are disclosed. One example technique includes fitting data in a dataset into a multiple variable model to obtain a set of estimated coefficients. The dataset having data representing multiple entries each containing an identification of a combination of multiple payloads included in a build of a software product and a corresponding value of a performance metric of executing the build at a computing device. The payloads individually represent a source code change, a feature enablement, or a configuration modification of the software product. The estimated coefficients individually correspond to one of the payloads. The method further includes in response to determining that a corresponding estimated coefficient of one of the payloads has an absolute value that is greater than a preset threshold, indicating that a software defect is likely present in the corresponding payload.

Abstract: Analyzing energy consumption of one or more computer systems based on gathered telemetry data. Telemetry data is accessed from computer systems. The telemetry data includes parameters, each associated with a data type. The telemetry data is organized into data sets that each include at least one of the parameters. Each data set is associated with one computer system, and includes an energy consumption parameter indicative of an amount of energy used. The data sets are organized into data set clusters based on the at least one parameter included in each data set. For each cluster, each data set that satisfies an energy consumption threshold associated with further analyzing the data set to determine a cause of the energy amount used may be identified. The identified data sets are analyzed to find patterns associated with the at least one parameter that are likely cause of the amount of energy used.

Abstract: A device is described that includes a sensor portion and a chassis portion. The sensor portion includes a plurality of sensing devices. The chassis portion is connected to the sensor portion and includes a first track and a second track. The second track is positioned adjacent the first track. The first and second tracks cooperate to substantially cover an entire width of the chassis portion.
