Abstract: Systems and methods for providing web service instances to support traffic demands for a particular web service in a large-scale distributed system are disclosed. An example method includes determining a peak historical service load for the web service. The service load capacity for each existing web service instance may then be determined. The example method may then calculate the remaining service load after subtracting the sum of the service load capacity of the existing web service instances from the peak historical service load for the web service. The number of web service instances necessary in the large-scale distributed system may be determined based on the remaining service load. The locations of the web service instances may be determined and changes may be applied to the large-scale system based on the number of web service instances necessary in the large-scale distributed system.

Abstract: One or more frames sampled from a first media item of an event are analyzed to identify one or more candidate event periods within the one or more frames. For each of the one or more frames, whether a candidate event period of the one or more candidate event periods satisfies one or more conditions is determined. Responsive to determining that the candidate event period of the one or more candidate event periods satisfies the one or more conditions, the candidate event period is identified as an actual event period used to divide a time the event. Mapping data that maps the actual event period to a timestamp associated with a respective frame of the one or more frames of the first media item is generated.

Abstract: The present document describes techniques for safe battery charging during high ambient temperatures. These techniques extend device runtime during peak use periods when ambient temperature is high by increasing the possibility for battery charging during high ambient temperature conditions. In an example, a device, during high ambient temperatures, checks future ambient temperatures over a network to identify if the minimum future ambient temperature over a block of time within the next N number of days is predicted to be sufficiently low that, when combined with device-performance throttling, is estimated to reduce the temperature of the battery to below the maximum charge temperature to enable the battery to be safely charged. The device can also use the future ambient temperatures to budget current battery usage by implementing and/or adjusting device-performance throttling.
