Abstract: Various embodiments of the present technology include an improved system for measuring the impacts of feature rollouts on machine utilization and service performance. More specifically, embodiments of the present technology include an exposure control system based on randomized machine assignments and a corresponding score card for comparing machine utilization metrics. In an embodiment, a computing apparatus identifies a new feature in a codebase, wherein the codebase has been updated with the new feature across multiple resources, enables the new feature for a target group of the multiple resources while keeping the new feature dormant for a control group of the multiple resources, collects performance information for the target group and the control group for a time period, and generates a visualization of one or more differences between the performance information for the target group and the performance information for the control group for the time period.

Abstract: Systems, components, devices, and methods for transferring files are provided. An example file is a container file comprising a plurality of component files. A non-limiting example method is a method for transferring a container file over a network to a remote device. The method includes the step of accessing a container file, the container file comprising a plurality of components. The method also includes the step of transmitting metadata information for the plurality of components to the remote device. The method further includes the step of determining components from the plurality of components to transmit to the remote device. The method additionally includes the step of transmitting component data items for the determined components to the remote device.

Abstract: The embodiments described herein generally relate to methods and systems for using a token as a bi-directional parameter of a long polling request for state updates. A client polls a server for state updates, in which updates may be the result of a server event. Server state data is hashed to generate a token/hash representing the current state data. The server compares this token/hash to the token/hash received from the client in the polling request. If the tokens differ, the server sends the actual state data with the server token to the client. By using tokens as request parameters, unnecessary state updates are avoided, and client/server synchronization is achieved more quickly by restricting the pushing of data to state updates. Further, the client may force a response to a poll by sending an empty or random/default value for the token request parameter.
