Curtin development on uvt-kvm

uvtool (uvt-kvm) provides the ability to easily launch an ubuntu guest of kvm.

This can be used for testing curtin from bzr or from the Ubuntu archive.

For more information on getting started with uvtool, see Ubuntu doc. Once that is set up you can follow along here.

Note that much of this document is not uvt-kvm specific. That is just used as an easy way to get an Ubuntu vm with a spare disk. You could just as easily do this on a cloud instance (OpenStack, Azure, DigitalOcean).

This example shows how we might blur and unblur 4x4 images. Let b0 through b15 be pixels in a blurred image. For example, the pixel at coordinates (2,3) is b14, since 14 is 2+3*4. Likewise, let the pixels of an unblurred image be x0 through x15.

Whenever we blur an image x into a blurred image b, we average each pixel of x with the pixels around it, giving the corresponding pixel of b. For example:

b5 = 1/5*x1 + 1/5*x4 + 1/5*x5 + 1/5*x6 + 1/5*x9

The output pixel b5 is at (1,1), so we compute it by averaging the pixels at (1,0), (1,2), (2,1), (0,1), and (1,1). This formula is similar for all the other pixels. Thus, we get:

//Given this:
NSArray *objects = @[@1, @2, @3]

//These are equivalent in behavior
NSNumber *first = [objects objectAtIndex:0]
NSNumber *second = (NSNumber *)CFArrayGetValueAtIndex(objects, 0)

//But is the code that runs the same? Not so much… in the first one we do…
