Is there a typical state machine implementation pattern?
...ended to support multiple state machines, etc. Transition actions can be accommodated as well:
typedef void transition_func_t( instance_data_t *data );
void do_initial_to_foo( instance_data_t *data );
void do_foo_to_bar( instance_data_t *data );
void do_bar_to_initial( instance_data_t *data );

Why should we typedef a struct so often in C?
...int_new(int x, int y)
{
Point a;
a.x = x;
a.y = y;
return a;
}
becomes cleaner when you don't need to see the "struct" keyword all over the place, it looks more as if there really is a type called "Point" in your language. Which, after the typedef, is the case I guess.
Also note that whil...
Java generics type erasure: when and what happens?
...he constraints are etc. But when generics are used, they're converted into compile-time checks and execution-time casts. So this code:
List<String> list = new ArrayList<String>();
list.add("Hi");
String x = list.get(0);
is compiled into
List list = new ArrayList();
list.add("Hi");

What is the difference between encode/decode?
...ow). It is mainly there for historical reasons, i think. In Python 3 it is completely gone.
unicode().decode() will perform an implicit encoding of s using the default (ascii) codec. Verify this like so:
>>> s = u'ö'
>>> s.decode()

Here's a really simple example in JavaScript that illustrates the point:

var inner = function() {
console.log(a);
}
return inner; // thi...

Read text file into string array (and write)
