Update: Pernosco
In the two years since I left Mozilla I've been working on a new debugger (with Kyle Huey, most of that time). We call it Pernosco — "know thoroughly". Pernosco takes rr recordings of failing runs, analyzes them in the cloud, and provides a Web interface for developers to debug them. It uses components of rr but the debugger implementation is completely different. Pernosco's data-oriented approach has features and performance that rr's approach cannot match — and nor can any other debugger. We've reached the point where external users have used Pernosco to fix real bugs, and their response has been very enthusiastic. It's exciting!
Developers spend a lot of time figuring out bugs. We think Pernosco will create a lot of value for software development organizations. We intend to capture some of that value by offering Pernosco as a paid cloud service. We have many ideas for making debugging easier and more fun, and we need a sustainable business model to make them happen. It's especially important because debugging is an area that has been chronically under-invested in across the industry.
