It was really nice to be in Portugal last week for #SPLASH2023, but it is also nice to return to a wintry Boulder!

1/2 At OOPSLA? Come hear @cuplv student @meiershawn speak on "Historia: Refuting Callback Reachability with Message-History Logics," 4pm, Room II. In an event-driven app, some bugs can only be fixed by changing what callbacks are enabled at different times.

📣Two CUPLV papers at OOPSLA this year! 1. @MeierShawn and co-authors Sergio Mover, @GowthamK, and @bechang demonstrate how to do scalable reachability analysis in presence of callbacks. The tool Historia has analyzed 2M lines of android app source code and found real bugs!

I’m honored to have been invited by the PC to share some work of @cuplv student @MeierShawn and connect it with past work of @b1ackd0g. “There is no ‘program’ analysis.”
