gray2transparent

This small C++ program converts a grayscale OpenEXR image to an image with transparancy.

behaviour

• takes only red channel of RGBA into account, prints message if color isn't gray
• ignores pixels with transparancy already set tot a non-opaque value
• makes lighter colors more transparant: alpha = 1 - red

Badass git pull alternative

Add this in your path as git-up and git-reup (symbolic link) and it amps up your git pull by means of git up

1. Adds in a list of the commits you're pulling down
2. Auto-prunes remote branches
3. Defaults to pull --rebase - gets rid of unnecessary merge commits. If you don't know what rebase does, this is probably safe for you. If you know what rebase does, you should know where this will not be safe for you.

Kyle Neath, Ryan Tomayko and then Zach Holman basically figured out how to do this. TheSpyder found a small error on case sensitive file systems.
