WebAssembly
Debugging WebAssembly in browsers has historically been painful — you were staring at raw WAT (WebAssembly Text format) with cryptic variable names like $var0 and $var1. That's changed dramatically. Chrome 90+ and Firefox support DWARF debug information, letting you set breakpoints in your original Rust, C, or AssemblyScript source.
Testing
Webhook failures in CI are some of the most frustrating bugs to debug. The test passes locally but fails in CI. The webhook arrives but nothing happens.
Testing
JTAG and GDB together give embedded engineers precise, non-invasive control over firmware execution on real hardware. This guide covers JTAG protocol fundamentals, connecting via OpenOCD, remote GDB debugging, breakpoints and watchpoints for test validation, inspecting memory and peripheral registers, and scripting GDB with Python to run automated test assertions
