• $_POST vs. $_SERVER['REQUEST_METHOD'] == 'POST'

  - by Scott

  Some guy called one of my Snipplr submissions "crap" because I used if ($_SERVER['REQUEST_METHOD'] == 'POST') instead of if ($_POST) Checking the request method seems more correct to me because that's what I really want to do. Is there some operational difference between the two or is this just a code clarity issue?

• Is there any way to accomplish something like List<object> list = new List<int>() in C#?

  - by devoured elysium

  That is the question. What I want to accomplish is something similar to the following Java code: class A { } class B extends A { } public class Tests { public static void main(String [] args) { ArrayList<? extends A> lists = new ArrayList<B>(); } } (in which B extends A means B inherits from A) Is it possible at all? Thanks

  - by grep

  Hi, I have this code that works just fine on the development server but when I deploy the application, the session isn't created. What am I doing wrong? HttpSession session = req.getSession(true); session.setAttribute("loggedIn", new String("true")); Edit: The sessions are enabled. What I realized now is that the _ah_SESSION variable is not being created, not even on the development server (although it works).

• Is objective C 2.0 a proper superset of C?

  - by RankWeis

  I've heard that objective-C is a proper superset of C, but is objective-C 2.0? The reason I ask is that either it isn't, or I misunderstand the phrase 'proper superset', because this code is valid C syntax: import int main () { char *nil = "hello"; printf("%s\n",nil); } But does not compile in Objective-C 2.0. Obviously, this is an easily fixable problem, but I'm writing a paper, and feel that this is something that should be pointed out.
