Why is IoC / DI not common in Python?
...Python, I simply import from a different location using the same name. But now I am thinking if it's also possible the other way round by defining a MyClassInstances class to each MyClass in Java, which contains only static, fully initialized instances. That would be wired :D

How are 3D games so efficient? [closed]

Eeeeek!
I know that this question is old, but its exciting that no one has mentioned VSync!!!???
You compared the CPU usage of the game at 60fps to CPU usage of the teapot demo at 60fps.

How to redirect cin and cout to files?
...
Here is an working example of what you want to do. Read the comments to know what each line in the code does. I've tested it on my pc with gcc 4.6.1; it works fine.
#include <iostream>
#include <fstream>
#include <string>
void f()
{
std::string line;
while(std::getline(...
Foreign Key to non-primary key
... key, otherwise, data-garbage is the result sooner rather than later...
Now what you can do in this case (short of rewritting the entire application) is inserting a CHECK-constraint, with a scalar function checking the presence of the key:

Ruby: extend self
...ways helps to think of extend as include inside the singleton class (also known as meta or eigen class).
You probably know that methods defined inside the singleton class are basically class methods:
module A
class << self
def x
puts 'x'
end
end
end
A.x #=> 'x'

Split a module across several files
...threw out namespacing. Changing one file in a way unrelated to another can now break other files. Your use of 'use' becomes leaky (ie everything is like use super::*). You can't hide code from other files (which is important for unsafe-using safe abstractions)
