Looking for a really handy function to calculate the distance between 2 points on torus (think 2-dimensional grid that wraps around)?
Here is a simple C# implementation:
public static double Distance(Point a, Point b, int size)
{
    int x = Math.Abs(b.X – a.X);
    int y = Math.Abs(b.Y – a.Y);

    int minX = Math.Min(x, (size – [...]

// handy c# snippet I often use for sorting generic collections
// using generic List of type Foo

list.Sort(delegate(Foo foo1, Foo foo2) {
    return foo1.bar.CompareTo(foo2.bar);});
Short and sweet;)
