``*buf`` means "unpack everything in `buf` as if it where written as 
positional arguments".  It is not some "pointer dereferencing" syntax, as 
Python doesn't have pointers as data types.  After argument unpacking it 
is not allowed to have other positional arguments.  That's the syntax 
error.

>From where do you get `recv()` anyway?  And what is `my_socket`?  Most 
certainly not an instance created with `socket.socket` because then you 
would use the `recv()` method of that object.
