Reverse and time-travel debugging with GDB 15, LLDB 19, rr, and Pernosco; Chrome DevTools 2025 with AI assistance and MCP; built-in inspectors in Bun, Deno, and Node; the pdb / pdbpp / ipdb / pudb / debugpy lineup for Python; Rust dbg! and tokio-console; Go Delve; Java JFR + JMC; eBPF with bpftrace and Pixie; Valgrind, ASan, MSan, TSan, UBSan; the DAP protocol; and AI-assisted debugging. All anchored to hypothesis-driven scientific debugging and to real field reports from Coupang, Naver, Kakao, Cookpad, Mercari, and HSAS.
