btw, Mac OS X also supports ACL. I haven't looked into. Probably works well there just because it's commercial.
to understand bitcoin, is first of all be able to “mine” it. That's my intention of writing a tutorial.
apparently, the best way to match images is to check the color map. This is my guess from seeing the behavior of Google's Image search. When you search a image that's rare or not on the web, you get results that's just images of similar color map.
