Sy Brand’s dive at NDC TechTown 2025 strips the “magic” off native debuggers, revealing how breakpoints are set, registers and memory are poked, debug data is parsed, and stepping, stack unwinding, and expression evaluation really work under the hood. Focusing on x64 Linux, you’ll see you’re not just hitting “pause”—you’re orchestrating a complex dance between hardware and OS.
Most of these core ideas map to other platforms too, so whether you’re on Windows, macOS, or something else, you’ll level up your debugging game with a deeper, more confident understanding of your tools.
