This was on hacker news a few days ago but there wasn't much interest, which is surprising. Setting a data breakpoint, then rewinding time, then fixing the error in code (while game is running), hot-reloading code and continuing the run with it fixed. All from a recording of a panic dump from another user. This is next level stuff. Extremely impressive.
