+## Title: Advanced Debugging Techniques in Practice
+
+### Abstract 
+
+It's been ten years since the first release of "rr", an open-source
+record-and-replay debugger with many real-world users. It's been five years
+since the release of "Pernosco", a commercial omniscient debugger with some
+real-world users. I'll give an overview of these tools and the technology
+behind them. I'll explain why users adopted these tools and how they are used
+in practice. Just as importantly, I'll present my understanding of why users
+have NOT adopted these kinds of tools and what we might be able to do about
+that.

+### Bio 
+
+In 2001 Robert graduated with a PhD in computer science from Carnegie
+Mellon University, supervised by Daniel Jackson and Jeannette Wing, on
+polymorphic type inference for context-sensitive alias analysis for Java code.
+From 2001 to 2004 he worked at IBM Research on dynamic program analysis tools.
+From 2000 he moonlighted as a volunteer working on the Mozilla open source
+project, which became Firefox. In 2005 he moved back to New Zealand to work
+full-time on Firefox's browser engine; Mozilla awarded him the title of
+Distinguished Engineer. In his last few years at Mozilla he led the development
+of "rr", a practical record-and-replay debugger supporting reverse execution,
+used by many developers inside and outside Mozilla to the present day. He
+continues as an rr maintainer to this day. In 2016 he left Mozilla to co-found
+Pernosco, a startup working on cloud-based, omniscient debugging leveraging rr.
+In 2022 he joined Google Research to work on various projects mostly unrelated
+to debugging. He lives in New Zealand and enjoys hiking, board games and lay
+preaching.
