+
+This document contains specifics about the workings of the Odin programming
+language, dynamic linking and state management design patterns. These are
+tested and validated findings, for continued reference by me.
+
+## Dynamic Library Memory
+
+When a program loads in a dynamic library, what happens with package globals?
+
+Findings (macOS):
+- The package globals are shared between the host and the lib
+- After hot reloading the lib, the memory of the packge is not refreshed,
+  it keeps pointing to the package global of the host
+
+The clanker states this is due to "flat-namespace symbol interposition".
+
+Linux "ELF has symbol preemption: when resolving references, ld.so searches
+globals scope in order — executable first, then loaded shared objects".
+
+Windows PE has no interposition at all, every module (exe and each DLL) has its
+own symbol table.
