Editing binaries

This article explains the concept and practical utility of directly editing binary files. It argues that while often seen as unconventional, binary patching is a powerful technique for fixing bugs in closed-source software, ensuring compatibility with non-standard CPUs, or resolving emergencies like a faulty auto-update. The author provides a rationale for the practice and begins a practical demonstration using basic tools like lldb and a hex editor.
