I'm wondering how to implement prototypal inheritance in Python. It seems like the way to do this would be to either
use a metaclass to cause instantiations to actually be classes, rather than objects, or
use some magical powers to transform an existing object into a class.
The second method would seem to be more flexible, in that it could be applied to existing objects of varied types, while the first would likely be more convenient for typical use cases.
Insights on the practicality of these two approaches, as well as alternative suggestions, are hereby requested.
This might seem like a bit of a design/css question but i really need some help.

It works on every browsers imaginable except chrome.
By it works i mean it applies a class .error that sets the borders to 1px solid #f00 which is a red border. In chrome for some reason you cannot change it no matter what!
Anybody got any ideas?

Hi all,
I have downloaded the PHP class from github which is the wrapper for their Open Graph API. I can log in and list freinds and images etc. But what I am really struggling with is allowing for extended permissions to allow posting to a users wall.
I know somewhere I need to add "scope=publish_stream" to allow this option and can only assume it is on the getLoginUrl method but I am having next to know joy with it.
Can anyone help me.

What's the main point behind putting variables and method signatures inside ApplicationDelegate.h in Objective-C ? By doing this, all those methods and variables are seen by another view controller classes? Is that the point?
And also: is there only one application delegate class inside each project?
Is it possible to reliably determine the compilation time stamp of a given class for both java applications running locally and as applets and/or JNLP webapps ?
I know that you can get a reference to a static method like this:
typedef void (*pointer)();
pointer p = &MyClass::MyMethod;
But is there a way to get a reference to the class itself?
I develop a game that has a big number of buttons (25).
I want to know if i can access them without initiating them in interface (.h) in my implementation class.
I have developed an application using Eclipse IDE. After creating the application I exported the project in jar format. When I am trying to run this jar file, I get the error: Unable to load main class. Please Help.
I am trying to create new object of other class in a for loop. like
for(int i =0;i<10;i++){
Computer p1=new Computer(10,20);
}
and when I try anywhere to reach p1.someAction(); it say you must declare p1. But if I declare it on top of program how can I create again in loop? I also try only Computer p1; but it gave exeption ..
I use a stateless session and the follow HQL.
CreateQuery("select a from Address a")
My Address Class has many BankDetails but i can't access. If i use a normal session it works. What can I do?
Lets say I have
class Person
{
public Person(int age, string name)
{
Age = age;
Name = name;
}
public int Age{get;set}
public string Name{get;set}
}
and I would like to create a method that accepts a string that contains either
"age" or "name" and returns an object with the value of that property.
Like the following pseudo code:
public object GetVal(string propName)
{
return <propName>.value;
}
How can I do this using reflection?
I am coding using asp.net 3.5, c# 3.5
in the navigator i can only see the current class' members.
is there a way to include the parents' members.
cause it is very useful when working with a framework, then you don't have to look for them in the documentation.
i think this is available in eclipse but not netbeans.
I know Java's generics are somewhat inferior to .Net's.
I have a generic class Foo<T>, and I really need to instantiate a T in Foo using a parameter-less constructor. How can one work around Java's limitation?

I have a table view that gets refreshed two different ways. One is through a button and the other is when I call my refresh method, which is the same method that I use for the button, but for some reason, when I hit the button it works, but when I call it through a different class it doesn't.
Here's the code that I use to refresh the tableview:
Msqv *qv = [Msqv new];
[qv refresh:self]; //refresh is an IBAction that is used by the button
