The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

CIAdditionCompositing - Adds color components to achieve a brightening effect. This filter is typically used to add highlights and lens flare effects.
CIAffineClamp - Performs an affine transform on a source image and then clamps the pixels at the edge of the transformed image, extending them outwards. This filter performs similarly to the CIAffineTransform filter except that it produces an image with infinite extent. You can use this filter when you need to blur an image but you want to avoid a soft, black fringe along the edges.
CIAffineTile - Applies an affine transform to an image and then tiles the transformed image.
CIAffineTransform - Applies an affine transform to an image. You can scale, translate, or rotate the input image. You can also apply a combination of these operations.
CIAreaAverage - Calculates the average color for the specified area in an image, returning the result in a pixel.
CIAreaHistogram - Calculates a histogram for the specified area in an image, returning the result in a 1D image.
