Leveraging Fine-grained Data Flows in Web Applications

A modern web page contains megabytes of HTML, CSS, images, and JavaScript. Loading such a page requires a browser to evaluate a complex dependency graph involving those resources; once the page is loaded, subsequent interactions between those resources and the user can lead to tricky-to-diagnose bugs. In this talk, I’ll describe how tracking fine-grained data flows can allow us to reduce page load times by prioritizing the loads of the highest ancestors in the data flow graph. I’ll also describe initial work in using data flows to assist with time-travel debugging (in which developers use a logging-and-replay framework to analyze buggy program executions).

James Mickens is an associate professor of computer science at Harvard University. His research focuses on the performance, security, and robustness of large-scale distributed web services. Mickens received a B.S. degree in computer science from the Georgia Institute of Technology in 2001. In 2008, he received a Ph.D. in computer science from the University of Michigan. Before coming to Harvard, he spent six years as a researcher at Microsoft. He is also the creator of Mickens-do, a martial art so deadly that he refuses to teach it to anyone (including himself).
