Time Travel Debugging - It’s Time to Debug Different
summary
Demos show a recorder + reverse debugger workflow that captures non‑deterministic inputs, replays execution and lets developers step backwards to the root cause; example: test 2011 asserts because a sqrt of -1 is cast into an unsigned char producing 0 instead of expected 15. Tools demonstrated: UDB, a 1 GB ring buffer default, ~2–5x runtime hit and serialized threads; Live Recorder for CI artifacts and portable captures; RR as an open source alternative.
