Hack everything without fear

A call to action for developers to embrace open source by actively reading, debugging, and patching unfamiliar codebases rather than shying away from them. The author argues that all open source code is accessible with the right mindset and tools like gdb and git grep, and that learning just enough of an unfamiliar language to fix a specific bug is both practical and valuable. Overcoming the fear of foreign code is framed as a core skill of effective programmers.
