Go Socket Programming Made Simple
Go simplifies C's socket system calls into fewer, more usable APIs. TCP programming uses net.Listen with interfaces that abstract connections and listeners. UDP works through net.ListenPacket. Handle port conflicts with socket options like SO_REUSEADDR.

How Defer Works Under the Hood
Go's defer statement creates linked lists of functions to run before a function returns. The compiler inserts special calls at defer declarations and before returns. Understanding this mechanism helps explain why defer runs in LIFO order and how it interacts with return values.
