(Mac vs PC) vs Linux

I'm laughing my head off, the Novel spoofs on the Mac/PC ads (here and here) are hillarious. As I mentioned on a previous post, the originals were quite annoying, and this really neatly hits the spot for me... Rock on, Novell !

NetBeans Groovy console

Alright, I didn't think I'd be putting it out there, but since
Geertjan blogged about it, here is the source to what I was doing with
the Groovy console in NetBeans.. I didn't think I'd be putting it
somewhere, since it's a bit of a hack (a proper solution to the
problem would probably use GroovyShell to interpret things and use
purely NetBeans for the creation of the UI end of things). But, since
it's out there in the wild, here is my "New and Improved" NetBeans groovy console.
One cool thing to note is that it picks up the Groovy Console key mappings, thus all shortcuts work exactly the same.
