Abstract: Various embodiments include a method and system for high-volume distributed script error report handling. A group of user terminals may be selected to report errors, where the group of user terminals is a subset of user terminals having open user session and the group of user terminals is smaller than a predetermined threshold value. An error report, generated by a user terminal in response to a script error, may then be received, where the user terminal is in the group of user terminals selected to report errors. The received error report may then be processed to create a processed error report. The processed error report may then be presented to a service user.

Abstract: Methods, systems and media for profiling CPU performance are provided. In one example, a method for profiling CPU performance includes generating a CPU profiling data file using a profiling tool, loading a flame graphing tool into a browser, loading the CPU profiling data file into a profiling page of the browser using the flame graphing tool, converting the loaded CPU profiling data file into an aggregated JSON format, and using the flame graphing tool to generate a flame graph using the aggregated JSON data.

Abstract: Various embodiments include a method and system for high-volume distributed script error report handling. An error report group threshold may be obtained. The error report group threshold may be determined by available computing resources, at an error facility, to receive error reports. A subset of current user terminals with representative user terminal environments may be identified. The subset may have a cardinality less than the error report group threshold. Members of the subset may be notified to report errors for a distributed program.

Abstract: A browser emulator is provided. An example browser emulator system includes a communications module to receive requests for web pages from a browser application, a document object model (DOM) interceptor to intercept an initial document object model (DOM) provided by the web application, an activator to activate a browser emulator, and a DOM manipulator to generate a modified DOM. A marked-up document that corresponds to the modified DOM includes an event interceptor that replaces JavaScript code associated with the original DOM provided by the web application.
