Node.js cross-origin POST. You should response for OPTIONS request first. Something like this.
if (req.method === 'OPTIONS') {
console.log('!OPTIONS');
var headers = {};
// IE8 does not allow domains to be specified, just the *
// headers["Access-Control-Allow-Origin"] = req.headers.origin;
headers["Access-Control-Allow-Origin"] = "*";
headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";

The Liang-Barsky algorithm for line-rectangle collisions

The Liang-Barsky algorithm is a cheap way to find the intersection points between a line segment and an axis-aligned rectangle. It's a simple algorithm, but the resources I was pointed to didn't have particularly good explanations, so I tried to write a better one.

Consider a rectangle defined by x_min ≤ x ≤ x_max and y_min ≤ y ≤ y_max, and a line segment from (x_0, y_0) to (x_0 + Δ_x, y_0 + Δ_y). We'll be assuming at least one of Δ_x and Δ_y is nonzero.

Image depicting the situation

(I'm working with Flash, so I'll be using the convention that y increases as you go down.)

We want to distinguish between the following cases:
